Description

The present invention relates to an elevator guide rail centering device and an elevator guide rail centering method, and relates to an elevator guide rail centering device and an elevator guide rail related to a jig for positioning the guide rail in the work of installing the elevator guide rail in the hoistway. It is suitable for the centering method.

Inside the elevator hoistway, there are two guide rails that support the car from both sides, and the car moves up and down along these guide rails. The guide rail is erected by connecting rails with a length of 3 to 5 meters, and is installed on the wall or beam of the hoistway with brackets. It should be noted that the guide rails are required to be positioned and installed with high accuracy so as to be vertical in consideration of riding comfort while the elevator is running.

Conventionally, the following method is known as a method of positioning the guide rail with high accuracy and centering the guide rail when installing the guide rail. First, lay a piano wire vertically beside the guide rail installation position to use it as the reference position. Then, the worker installs the first rail to be installed at the bottom while using the piano wire as a reference. Next, the remaining rails (rails from the uppermost stage to the second stage) are connected from the ceiling of the hoistway, suspended and temporarily fixed. After that, a worker on the work floor that goes up and down in the hoistway positions the rails of each stage in order from the bottom, using the piano wire as a reference, and fixes the guide rails to the walls and beams of the hoistway with brackets. To go. However, such high-precision positioning of the guide rail by the operator manually requires skill and time.

Here, for example, Patent Document 1 discloses an elevator guide rail centering device for the purpose of executing the guide rail centering work in a short time and shortening the construction period and labor saving of the installation work on the elevator. There is.

According to the centering device disclosed in Patent Document 1, a detection mechanism that measures the misalignment of the guide rail with respect to the reference line and a correction mechanism that corrects and moves the guide rail so as to correct the misalignment measured by the detection mechanism. By providing, the positioning of the guide rails of the second and subsequent stages can be automatically executed.

Specifically, in the centering device of Patent Document 1, the detection mechanism sets the positional relationship between the sensor and the guide rail grip portion and the relationship between the reference line (piano wire) and the guide rail target installation position. The deviation of the guide rail can be calculated from the position detection result of the piano wire. Then, the correction mechanism controls the actuator so that the deviation of the guide rail becomes equal to or less than the permissible value, and moves the jig holding the guide rail. By doing so, the centering device of Patent Document 1 can automatically position the guide rail with reference to the piano wire.

Japanese Unexamined Patent Publication No. 5-278968

As described above, the centering device of Patent Document 1 can automatically position the guide rail with reference to the piano wire, but secures sufficient rigidity in the car frame in which the centering device is installed. There has been a problem that positioning of the guide rail can be difficult because it is expected to be difficult to do.

Specifically, in the centering device of Patent Document 1, a rail gripping mechanism for gripping the guide rail is installed on the upper part of the car frame, and a worker rides on the work floor in the car frame based on the positioning result. Perform work such as fixing the bracket. The car frame is fixed to the fixed guide rail by a support mechanism installed at the bottom of the car frame, but it is expected that it will be difficult to secure sufficient rigidity by itself. If sufficient rigidity is not secured in this way, the car frame will shake when the worker moves on the work floor during the bracket fixing work, and the centering device attached to the upper part of the car frame will also shake. , The problem that the position of the guide rail is not fixed arises.

Further, in Patent Document 1, as a modification, a support mechanism that expands and contracts with an actuator is arranged on a jig that holds the guide rail (the entire cage frame is regarded as a jig), and the support mechanism pushes the hoistway wall. It is also disclosed that the jig is moved. If it is possible to reliably press against the hoistway wall, it is assumed that sufficient rigidity can be secured.

However, the positions of the beams and steel frames of the hoistway on which the above support mechanism can be pressed vary depending on the construction site, and even at the same site, they may differ on each floor. Therefore, it can be used only in a limited field where a beam or a steel frame is always present at the place where the above support mechanism is attached, and as a result, highly accurate positioning of the guide rail is surely performed. There was a problem left for that.

The present invention has been made in consideration of the above points, and an elevator guide rail core capable of reliably performing highly accurate automatic positioning of the guide rail regardless of the position of the beam or the position of the wall in the hoistway. This is an attempt to propose a centering method for a centering device and an elevator guide rail.

In order to solve such a problem, the present invention is an elevator guide rail centering device that is placed on a work floor moving in the hoistway of an elevator and aligns a guide rail installed on the opposite side surface of the hoistway. A jig that grips the pair of guide rails at both ends, and a jig receiver that horizontally presses both ends against the mountable surface on which the guide rails can be installed on the opposite side surfaces of the hoistway. , A positioning mechanism that is arranged between the jig and the jig receiver and electrically changes and fixes the relative position of the jig with respect to the jig receiver, and detects the relative position of the jig with respect to a reference installed in the hoistway. An elevator including a reference detection device and a control device that automatically controls a positioning operation by the positioning mechanism so that the jig takes a predetermined relative position with respect to the reference based on a detection result by the reference detection device. A guide rail centering device is provided. In this elevator guide rail centering device, the positioning mechanism includes a first positioning device that electrically twists and displaces the relative position of the jig with respect to the jig receiver in the vertical axis direction to fix the jig, and the mounting device. A second positioning device that electrically translates and fixes the relative position of the jig with respect to the possible surface or the jig receiver in the uniaxial direction on the horizontal plane, and the relative position of the jig with respect to the jig receiver on the horizontal plane. It has a third positioning device that is electrically translated and fixed in a uniaxial direction, which is different from the second positioning device.

Further, in order to solve such a problem, in the present invention, an elevator guide rail centering device that is placed on a work floor moving in an elevator hoistway and aligns a guide rail installed on the opposite side surface of the hoistway. The following elevator guide rail centering method using the above is provided. Here, the elevator guide rail centering device has both ends on a jig that grips the pair of the guide rails at both ends and a mountable surface on the opposite side surface of the hoistway where the guide rails can be installed. A jig receiver that is pressed and fixed horizontally, a positioning mechanism that is arranged between the jig and the jig receiver and electrically changes and fixes the relative position of the jig with respect to the jig receiver, and a positioning mechanism installed in the hoistway. It has a reference detection device that detects the relative position of the jig with respect to the reference, and a control device that automatically controls the positioning operation by the positioning mechanism, and the positioning mechanism vertically sets the relative position of the jig with respect to the jig receiver. The first positioning device, which is electrically electrically twisted and displaced and fixed in the axial direction, and the relative position of the jig with respect to the mountable surface or the jig receiver are electrically translated and moved in the uniaxial direction on the horizontal plane. A third positioning device that electrically translates and fixes the position of the jig relative to the jig receiver in a uniaxial direction different from that of the second positioning device on the horizontal plane. And have. Then, in this elevator guide rail centering method, after the pair of guide rails is gripped at both ends of the jig, the positioning mechanism does not change the relative position of the jig with respect to the jig receiver. A start step for fixing the third positioning device, a position deviation calculation step for the reference detection device to detect the relative position of the jig with respect to the reference, and a detection result by the position deviation calculation step after the start step. Based on the above, the control device includes a positioning step for automatically controlling the positioning operation by the positioning mechanism so that the jig takes a predetermined relative position with respect to the reference, and is determined by the positioning step. Based on the result of the positioning operation, the guide rails gripped at both ends of the jig are mounted on the mountable surface.

According to the present invention, in the centering work of the guide rail of the elevator, the automatic positioning of the guide rail with high accuracy can be reliably executed regardless of the position of the beam or the position of the wall in the hoistway.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

(1) First Embodiment FIG. 1 is a perspective view of an elevator guide rail centering device according to the first embodiment of the present invention. Further, FIG. 2 is a top view of the elevator guide rail centering device shown in FIG.

(1-1) Structure of Elevator Guide Rail Centering Device 100 As shown in FIG. 1, the elevator guide rail centering device 100 according to the first embodiment includes a jig receiver 1, a positioning mechanism 2, a jig 3, and a jig 3. It is configured to include a control device 4. The structure of the elevator guide rail centering device 100 will be described with reference to FIGS. 1 and 2.

(1-1-1) Jig receiver 1
The jig receiver 1 includes backing plates 5 at both ends, a beam 6, and operation buttons 7 for operating each part of the jig receiver 1.

The backing plate 5 is a plate for hitting the plate (or beam, wall) 9 installed at the bracket mounting position of the hoistway 8, and is configured to include a rod 10 for supporting the plate.

The beam 6 has a built-in push-out mechanism for the rod 10, and the push-out mechanism electrically expands and contracts the rod 10 based on the operation of the operation button 7 to push out and store the left and right backing plates 5. ..

The operation button 7 is a button for operating the movement of the backing plate 5, and when the backing plate 5 is pushed out by operating the operation button 7, the plate (or beam, wall) at the place where the bracket receiver 11b is fixed is fixed. The jig receiver 1 is fixed to the hoistway 8 by hitting 9 and stretching with a predetermined force. Further, when the operation button 7 is operated to return (store) the backing plate 5, the jig receiver 1 is released from being fixed to the hoistway 8.

Here, the bracket receiver 11b is supplemented. Although the detailed procedure will be described later, in the centering work of the guide rail 25 in the present embodiment, after the guide rail 25 is positioned, the bracket 11 for fixing the guide rail 25 is based on the positioning result. Is fixed to the wall of the hoistway 8, so that the guide rail 25 is fixed at a predetermined position.

To explain the fixing of the bracket 11 in more detail, as shown in FIG. 2, the bracket 11 is composed of a bracket main body 11a and a bracket receiver 11b. Then, when the guide rail 25 is positioned, the worker fixes the bracket receiver 11b to the plate (or beam, wall) 9 provided on the wall of the hoistway 8 based on the positioning result. The position where the bracket receiver 11b on which the plate 9 is provided can be attached is referred to as a "bracket attachment position". Further, the worker attaches the bracket body 11a to the guide rail 25 with a clip, and welds the bracket body 11a and the bracket receiver 11b to fix the guide rail 25 to the hoistway 8.

In the following description, such fixing of the bracket body 11a and the bracket receiver 11b will be collectively referred to as "fixing of the bracket 11 (attachment of the bracket 11)". In this case, it can be said that the bracket mounting position by the plate 9 is a position where the bracket 11 can be mounted. Then, in the present embodiment, the guide rail 25 is positioned with the jig receiver 1 fixed to the bracket mounting position (plate 9), so that the state in the hoistway 8 other than the bracket mounting position (beam). Regardless of the position (position, wall position, etc.), the bracket 11 can be reliably fixed to the bracket mounting position (plate 9), and the guide rail 25 can be centered.

Further, in the following description, the fact that the guide rail 25 is fixed to the mounting position (plate 9) of the hoistway 8 via the bracket 11 as described above is defined in a broad sense as "the hoistway 8 (mounting position) of the guide rail 25". , Fixing to plate 9) "and so on.

Further, as will be described later with reference to FIG. 7, in the start preparation work of the guide rail centering work, the elevator guide rail centering device 100 is placed on the handrail portion of the work floor 34, and at this time, the jig receiver 1 is placed. Joints 12 for setting (putting) on the handrail are attached to the left and right of the beam 6. The joint 12 is configured by inserting a spring between the portion for fixing the handrail and the portion for fixing the beam 6, so that the jig receiver 1 is supported in a state of being lifted from the handrail. By mounting the elevator guide rail centering device 100 on the handrail via such a joint 12, even if the work floor 34 shakes, the jig receiver 1 and the jig 3 located above the jig receiver 1 can be moved. The effect can be eliminated. More specifically, the spring of the joint 12 can absorb not only the vertical sway of the work floor 34 but also the sway in the front-back and left-right directions, so that the influence on the jig receiver 1 and the jig 3 is blocked. can do.

(1-1-2) Positioning mechanism 2
The positioning mechanism 2 is a mechanism capable of "positioning the jig 3" that electrically changes and fixes the relative position of the jig 3 with respect to the jig receiver 1, and is attached to the beam 6 of the jig receiver 1. As shown in FIGS. 1 and 2, the positioning mechanism 2 includes a one-axis rotation angle positioning device 13, two orthogonal axis translational direction positioning devices 14 and 15, a rotation angle positioning device 13, and a translational direction positioning device 14. It is provided with a bar 16 to which (and a translational direction positioning device 15) is attached, and an operation button 17 provided on the bar 16 for operating each part of the positioning mechanism 2.

In this description, in order to explain the details of the positioning device for each axis, the left-right direction is the x-axis, the up-down direction is the y-axis, and the front-back direction is the z-axis when viewed from the front of the hoistway 8. At this time, the positioning devices for each axis constituting the positioning mechanism 2 are the rotation angle positioning device 13 around the y-axis, the translational direction positioning device 14 in the z-axis direction, and the translational direction positioning device 15 in the x-axis direction.

First, the structure of the rotation angle positioning device 13 will be described in detail.

FIG. 3 is a diagram for explaining the structure of the rotation angle positioning device. The rotation angle positioning device 13 is an electric positioning device that vertically twists and positions the relative position of the jig 3 with respect to the jig receiver 1 in the vertical axis direction (around the y-axis), and as shown in FIG. 3 and the like, the rotation angle positioning device 13 is an electric positioning device. A worm wheel (rotary table) 131 that can rotate around a rotation axis, an actuator 132 for controlling a rotation angle, and a clutch 133 for fixing (locking) or freeing the rotation axis of the rotation table 131. Be prepared.

The actuator 132 includes a motor 134 and a worm gear (reducer) 135. In the actuator 132, by setting the reduction ratio by the speed reducer 135 to be relatively high (for example, about 100), the rotation shaft of the rotary table 131 can be fixed (locked) only by stopping the motor 134.

The clutch 133 is composed of a disc 136 and a brake 137. When the electromagnetic solenoid is energized based on the operation of the operation button 17, the clutch 133 is engaged, and the motor shaft (rotating shaft of the motor 134) and the rotating shaft (rotating shaft of the rotary table 131) are engaged. On the other hand, when the energization of the electromagnetic solenoid is cut off based on the operation of the operation button 17, the clutch 133 is disengaged and the motor shaft and the rotating shaft are free to rotate.

Further, as shown in FIG. 3, in the rotation angle positioning device 13, the brake 137 of the clutch 133 is fixed to the stay 138 attached to the bar 16, and the disc 136 of the clutch 133 is fixed to the worm wheel (rotary table) 131. , The rotation shaft of the worm wheel 131 and the actuator 132 that meshes with the worm wheel 131 are fixed to the beam 6 and are connected to the bar 16 and the beam 6.

By having the above structure, in the rotation angle positioning device 13, when the brake 137 is free (that is, when the clutch 133 is disengaged), the bar 16 can freely rotate with respect to the beam 6, and the brake When the 137 is locked (that is, when the clutch 133 is engaged), the rotation angle of the bar 16 around the y-axis is positioned by the motor 134.

Next, the structure of the translational direction positioning device 14 will be described in detail. The translational direction positioning device 14 is an electric positioning device that positions the relative position of the jigging tool 3 with respect to the jigging tool receiver 1 in the uniaxial direction (z-axis direction) on the horizontal plane by relative translational movement, and is an electric positioning device of the rotary table 131. It is arranged on the rear upper surface of the bar 16 which is fixed on the top and extends in the z-axis direction. Therefore, the arrangement of the translational direction positioning device 14 is deviated from the z-axis direction of the coordinate system set on the hoistway 8 by the angle at which the rotary table 131 is rotated (see FIG. 2).

FIG. 4 is a diagram for explaining the structure of the translational direction positioning device. As shown in FIG. 4 and the like, the translational direction positioning device 14 has a structure in which two upper and lower slider units having sliders that can move in the z-axis direction are connected to each other and can be translated in the z-axis direction.

Specifically, the slider unit of the first stage (lower side) controls the rotation of the linear guide (linear guide) 141, the slider 142 that can be moved by the rotation of the screw shaft 143, and the screw shaft 143. It includes an actuator 144 that controls the movement of the slider 142.

In the first-stage slider unit, the actuator 144 rotates the screw shaft 143 to move the slider 142, whereby positioning can be performed in the direction of the screw shaft 143 (z-axis direction). A second-stage slider unit with a lock mechanism 149 is supported on such a first-stage slider unit.

The second stage (upper side) slider unit includes a linear guide (linear motion guide) 145, a slider 146 (slider portion 146a, main body 146b), and a brake 147.

Each bracket 151 to 153 shown in FIG. 4 has the following roles. The bracket 151 is attached to the bar 16 and has a role of fixing the first-stage linear guide 141 to the bar 16. The bracket 152 has a role of attaching the second-stage linear guide 145 to the first-stage slider 142. The bracket 153 has a role of attaching the translational direction positioning device 15 in the x-axis direction to the second-stage linear guide 145.

Here, in the second-stage slider unit, the lock mechanism 149 for the slider 146 is formed by the brake 147 and the surface of the linear guide 145 on the brake 147 side (brake sliding surface 148).

When the electromagnetic solenoid is energized based on the operation of the operation button 17, the lock mechanism 149 operates the brake 147 by the electric solenoid, and the brake 147 grips the brake sliding surface 148 of the second stage linear guide 145. The second-stage slider 146 is fixed to the second-stage linear guide 145 and also fixed to the first-stage slider 142 (fixing the first-stage and second-stage sliders 142 and 146). Further, the lock mechanism 149 releases the fixing of the first-stage and second-stage sliders 142 and 146 when the energization of the electromagnetic solenoid is cut off based on the operation of the operation button 17.

When the first-stage and second-stage sliders 142 and 146 are fixed by the lock mechanism 149 as described above, the position of the second-stage slider 146 in the z-axis direction is determined by the positioning mechanism of the first-stage slider 142. It is decided. On the other hand, in a state where the first and second stage sliders 142 and 146 are unlocked by the lock mechanism 149, the second stage slider 146 moves in the z-axis direction regardless of the movement of the first stage slider 142. You can move freely in translation.

Next, the structure of the translational direction positioning device 15 will be described in detail. The translational direction positioning device 15 is an electric motor that positions the relative position of the jig 3 with respect to the jig receiver 1 in another uniaxial direction (x-axis direction) on a horizontal plane different from the translational direction positioning device 14 by relative translational movement. Positioning device. The structure of the translational direction positioning device 15 in the x-axis direction may be the same as the structure of the translational direction positioning device 14 in the z-axis direction (see FIGS. 3 and 4), and detailed description thereof will be omitted.

The translational direction positioning device 15 in the x-axis direction is a position rotated 90 degrees around the y-axis between the jig 3 and the translational direction positioning device 14 in the z-axis direction (that is, a position capable of being translated in the x-axis direction). Is placed in. On the lower side of the translational direction positioning device 15 in the x-axis direction, the linear guide of the first-stage slider unit is provided by the bracket 153 in the same manner as the fixing of the linear guide 141 and the bracket 151 in the translational direction positioning device 14 in the z-axis direction. By being fixed, it is connected to the translational direction positioning device 14 in the z-axis direction. Further, the upper side of the translational direction positioning device 15 in the x-axis direction is connected to the jig 3 by fixing the second-stage slider (or the bracket fixed to the slider) to the arm 18 described later of the jig 3. NS.

With the above configuration, the translational direction positioning device 15 in the x-axis direction is in the first stage and in a state where it is not fixed (released) by the lock mechanism based on the operation of the operation button 17. When the second-stage slider can be freely translated in the x-axis direction and is fixed by the lock mechanism, the positions of the first-stage and second-stage sliders are fixed.

As described above, in the positioning mechanism 2, positioning around the y-axis by the rotation angle positioning device 13, positioning in the z-axis direction by the translational direction positioning device 14, and positioning in the x-axis direction by the translational direction positioning device 15 are possible. Is. Then, by arranging the positioning mechanism 2 having such an electric positioning device between the jig receiver 1 and the jig 3, the position of the jig 3 with respect to the jig receiver 1 can be freely changed and positioned. ..

(1-1-3) Jig 3
As shown in FIGS. 1 and 2, the jig 3 includes an arm 18 fixed to a second-stage slider of the translational direction positioning device 15 in the x-axis direction, an attitude sensor 19 for measuring the inclination of the arm 18, and an attitude sensor 19. Spacers 20 attached to the left and right sides of the arm 18, rail gripping devices 21 attached to the left and right sides of the arm 18 via the spacer 20, reference detection device 22 attached to the upper surface of the rail gripping device 21, and jig 3. It is configured to include an operation button 23 for operating each part and a display 24 for displaying the measurement result of the inclination of the arm 18 by the attitude sensor 19.

The arm 18 is a rod-shaped member arranged in the x-axis direction, and is attached near the center of the arm 18 to be fixed to the attitude sensor 19 and the second-stage slider of the translational direction positioning device 15 in the x-axis direction. A part (bracket) is arranged. Further, spacers 20 are attached to the left and right sides of the arm 18 as a member for adjusting the distance between the left and right guide rails 25 gripped by the rail gripping device 21 so as to be a predetermined distance. Supplementally, since the distance between the guide rails 25 differs depending on the width of the car, the spacer 20 having different dimensions can be replaced with the arm 18, so that the guide rails 25 have a predetermined distance (length) based on the width of the car. It is made possible to correspond to the above). Then, the rail gripping device 21 is attached to the outside of each spacer 20.

FIG. 5 is a triangular projection drawing of the rail gripping device. FIG. 5 shows one of the rail gripping devices 21 shown in FIG. 1 (specifically, the rail gripping device 21 attached to the left side of the arm 18 in FIG. 1) in the y-axis positive direction and the z-axis positive direction. A projection from is shown.

As shown in FIG. 5, the rail gripping device 21 grips the guide rail 25 having a so-called “T-shaped” shape by sandwiching it in the x-axis direction and the z-axis direction.

Specifically, the rail gripping device 21 uses a pair of a roller 26 on the top side that abuts the top of the guide rail 25 and a roller 27 on the bottom side that presses the bottom of the guide rail 25 from the back side to x-axis the guide rail 25. Hold in the direction. Here, for example, the roller 26 on the top side is a fixed type, while the roller 27 on the bottom side is a movable type so as to be attracted to the arm 18 side by the linear actuator 28. In this case, by pulling the roller 27 in contact with the bottom of the guide rail 25 toward the arm 18 until the top of the guide rail 25 is sufficiently in contact with the roller 26, the rail gripping device 21 pulls the guide rail 25 in the x-axis direction. Can be gripped.

The above-mentioned combination of the roller 26 and the roller 27 regarding the fixed / movable type is an example of the present embodiment, and may be a replacement combination, or a movable roller that can be fixed / released by each. May be adopted.

In particular, even if the roller 26 on the top side is normally used as a fixed type, it is preferable to have a movable (movable inward) structure when moving the guide rail 25. With such a structure, the dimensions (distance between the guide rails 25) that can be gripped by the rail gripping device 21 are larger than those in the case where the rollers 26 are always fixed in the rail gripping devices 21 on both sides of the arm 18. Since the range is widened, the application target of the guide rail centering work by the elevator guide rail centering device 100 can be expanded so that the work can be performed even when the wall width of the hoistway 8 is relatively narrow.

Further, the rail gripping device 21 grips the guide rail 25 in the z-axis direction by a pair of rollers 30 and rollers 31 that come into contact with both side surfaces of the guide rail 25. As shown in FIG. 5, the roller 30 is arranged so that one side surface of the guide rail is brought into contact with the fixed roller mounting member 29 to which the roller 26 on the top side is mounted in a direction orthogonal to the roller 26. Further, the roller 31 is arranged so as to hit the side surface of the guide rail 25 on the side opposite to the surface on which the roller 30 hits. Here, for example, the roller 30 is fixed, the roller 31 is movable, and the guide rail 25 is sandwiched from both sides by the linear actuator 32, so that the rail gripping device 21 z the guide rail 25. It can be gripped in the axial direction. The above-mentioned combination of the roller 30 and the roller 31 regarding the fixed / movable type is an example of the present embodiment, and may be a replacement combination, or a movable type having a lock mechanism that can be fixed / released by each person. A type of roller may be adopted.

As described above, the rail gripping device 21 can grip the guide rail 25 by sandwiching it in the x-axis direction and the z-axis direction, and such a rail gripping device 21 is provided on both ends of the arm 18 via the spacer 20. By doing so, the jig 3 can grip and release the left and right guide rails 25 based on the operation of the operation button 23 attached to the arm 18.

The reference detection device 22 is a sensor device for detecting the position (reference position) of the piano wire 33 as a reference when positioning the guide rail 25. The reference detection device 22 can fix the positional relationship with the guide rail 25 by being attached to the fixed roller attachment member 29 to which the roller 26 on the top side is attached. Further, for example, as shown in FIG. 1, the piano wire 33 is installed beside the guide rail 25 (see also FIG. 6 described later).

As the reference detection device 22, a conventionally known reference detection device (for example, the detection mechanism 4 disclosed in Patent Document 1) can be used. The description of the specific structure is omitted because it is disclosed in Patent Document 1 (for example, FIG. 4). Here, since the positional relationship between the sensor of the reference detection device 22 and the top of the guide rail 25 is known from the dimensions of the fixed roller mounting member 29 to which the sensor is mounted, the target position of the guide rail 25 and the piano The deviation of the guide rail 25 can be obtained from the difference from the positional relationship of the wire 33.

Then, the control device 4 enables the conventionally known correction control (for example, the control corresponding to the operation of the correction mechanism 5 disclosed in Patent Document 1) to be executed, so that the calculation result (guide) of the reference detection device 22 is executed. The guide rail 25 can be positioned based on the deviation of the rail 25). Specifically, as will be described later in step S25 of FIG. 8, the control device 4 controls the actuator of the positioning mechanism 2 so that the deviation of the guide rail 25 calculated by the reference detection device 22 is equal to or less than the allowable value. By moving the jig 3 that grips the guide rail 25, the guide rail 25 is positioned (which can also be said to be the positioning of the jig 3).

The posture sensor 19 is attached to the arm 18, and when the jig 3 is attached, the inclination of the arm 18 (that is, corresponding to the inclination of the jig 3) is measured, and the measurement result of how many times the attitude sensor 19 is inclined in which direction. Is displayed on the display 24. As the posture sensor 19, a conventionally known tilt sensor can be used, and the description of the specific structure thereof will be omitted. Further, instead of the posture sensor 19, a level or the like may be used.

(1-2) Elevator Guide Rail Installation Work An elevator guide rail installation work using the elevator guide rail centering device 100 according to the present embodiment will be described.

FIG. 6 is a diagram for explaining an elevator guide rail centering device installed on the work floor. FIG. 6 shows two guide rails 25 erected on the hoistway 8, a work floor 34 that moves up and down along the guide rail 25, and an elevator guide rail centering device 100 installed on the work floor 34. ,It is shown.

As described above, the two guide rails 25 that support the car from both sides are erected by joining a plurality of rails. In FIG. 4, the plurality of rails joined in this way are referred to as rails 25a, 25b, ..., 25z in order from the first step at the bottom to the top. That is, the rail 25a is a rail installed at the lowermost stage of the guide rail 25, and the rail 25z is a rail (also referred to as a top rail) installed at the uppermost stage of the guide rail 25.

In the present embodiment, the worker who installs the elevator guide rail is a preparatory work (start preparatory work) such as temporarily fixing the guide rail 25 by the multi-stage rails 25a to 25z and standing it in the hoistway 8. ) (See FIG. 7), the guide rail 25 (each rail 25a to 25z) is centered using the elevator guide rail centering device 100 (see FIG. 8). The specific procedure of the start preparation work and the centering work will be described below.

(1-2-1) Start Preparation Work FIG. 7 is a flowchart showing a procedure example of the start preparation work of the guide rail centering work according to the first embodiment.

According to FIG. 7, first, in step S11, the worker vertically lowers the piano wire 33 from the top of the hoistway 8 and installs it at a predetermined distance from the guide rail 25.

Next, in step S12, the worker installs the first-stage rail 25a to be installed at the bottom of the guide rail 25 with reference to the piano wire 33 installed in step S11.

Next, in step S13, the worker suspends the upper part of the top rail (rail 25z) taken into the pit (not shown) at the lower part of the hoistway 8 by using the lifting machine 35 attached to the ceiling of the hoistway 8. , The next rail (the rail installed one step below the uppermost step) is connected to the lower end of the rail 25z and added. Further, this rail replenishment work is repeated until the second rail 25b from the bottom is connected.

Then, in the next step S14, the worker moves the lower end of the rail group connected in a string from the top rail in step S13 (that is, the lower end of the second stage rail 25b) and the first stage fixed in step S12. The upper end of the rail 25a is connected, and the top rail (rail 25z) is temporarily fixed to the hoistway 8. As a result, the guide rail 25 by temporary fixing is erected in the hoistway 8.

Next, in step S15, the worker uses the lifting machine 35 to assemble a work floor 34 that moves up and down in the hoistway 8 along the guide rail 25.

Next, in step S16, the worker puts the elevator guide rail centering device 100 on the handrail portion of the work floor 34 assembled in step S15.

Then, in the next step S17, the worker gets on the work floor 34 and uses the lifting machine 35 to move the work floor 34 to a predetermined bracket mounting position. More specifically, the jig receiver 1 is positioned at the height of the "bracket mounting position" (corresponding plate 9 provided in the hoistway 8) to which the bracket 11 corresponding to the second rail 25b can be mounted. The work floor 34 is moved to.

The start preparation work is completed by performing the above steps S11 to S17, and after that, the worker performs the centering work of the guide rails 25 (each rail 25a to 25z) using the elevator guide rail centering device 100. be able to.

(1-2-2) Centering Work FIG. 8 is a flowchart showing a procedure example of the guide rail centering work in the first embodiment. Of the operations of each step shown in FIG. 8, the operations of steps S21, S22, S26, and S30 are operations performed by the worker. On the other hand, the operations of steps S23 to S25 and steps S27 to S29 are operations automatically performed by the elevator guide rail centering device 100 based on the operations by the operator (for example, the operations of the operation buttons 7, 17, and 23). Further, the work in step S23 may be performed by an operator instead of the automatic work by the elevator guide rail centering device 100.

According to FIG. 8, first, in step S21, the worker operates the operation button 23 of the jig 3 to grip the guide rail 25 (for example, the rail 25b in the case of the first centering work). As described above in (1-1-3), the jig 3 grips the left and right guide rails 25 by sandwiching the left and right guide rails 25 in the x-axis direction and the z-axis direction by the rail gripping device 21.

In the next step S22, the worker supports the jig 3 so that it is horizontal while checking the measurement result of the inclination of the jig 3 (arm 18) by the posture sensor 19 on the display 24.

Next, in step S23, the elevator guide rail centering device 100 fixes the jig receiver 1 to the hoistway 8 (plate 9) based on the operator operating the operation button 7 of the jig receiver 1. In the initial state when the jig receiver 1 is fixed in step S23, the rotation axis and the translation slider of the positioning mechanism 2 are not fixed. More specifically, the rotation axis (rotation table 131) of the rotation angle positioning device 13 is separated from the actuator 132, and each slider (for example, slider 142,) in the orthogonal two-axis translational direction positioning devices 14 and 15 is separated from the actuator 132. 146 etc.) is also not fixed.

Next, in step S24, the elevator guide rail centering device 100 fixes the rotation shaft and the translation slider of the positioning mechanism 2 which were not fixed in the above initial state.

Then, in step S25, the elevator guide rail centering device 100 performs the positioning operation of the guide rail 25 based on the operation of the operation button 23 of the jig 3 by the worker. More specifically, the control device 4 detects the position of the reference piano wire 33 by the reference detection device 22, and calculates the deviation of the position of the guide rail 25 based on the reference position. Then, the control device 4 controls the actuator of the positioning mechanism 2 so that the calculated deviation becomes equal to or less than the allowable value. That is, by controlling each positioning device (rotational angle positioning device 13, translational direction positioning device 14, 15) of the positioning mechanism 2, the displacement of the position of the guide rail 25 gripped by the rail gripping device 21 becomes equal to or less than the allowable value. To be.

In step S25, the guide rail 25 gripped by the rail gripping device 21 is positioned at an appropriate position. Therefore, in step S26, the worker brackets the bracket to the bracket mounting position (plate 9) based on the positioning result. 11 is attached, and the guide rail 25 (for example, the rail 25b in the case of the first centering work) is fixed to the hoistway 8.

Since the centering of the gripped guide rail 25 (for example, the rail 25b) is completed by the above step S26, the elevator guide rail centering device 100 moves to the centering of the next rail in steps S27 to S29. Therefore, the operation to return to the initial state is performed.

Specifically, in step S27, the elevator guide rail centering device 100 releases the fixed state of the rotation shaft and the translation slider of the positioning mechanism 2 fixed in step S24 based on the operation of the operation button 17 by the operator. ..

Then, in step S28, based on the operation of the operation button 23 by the worker, the elevator guide rail centering device 100 is the guide rail 25 (for example, the rail 25b) gripped by the jig 3 (rail gripping device 21) in step S21. Release the grip.

Then, in step S29, the elevator guide rail centering device 100 returns all the actuators (actuators 132, 144, linear actuators 28, 32) to the home position (initial position).

By the above operations of steps S27 to S29, the elevator guide rail centering device 100 returns to the initial state. It should be noted that each operation in steps S27 to S29 does not necessarily have to be executed based on the operation of the corresponding operation button performed by the operator. For example, the guide rail 25 (for example, rail 25b) in step S26 does not have to be executed. ) Is completed, the control device 4 may automatically perform the processes of steps S27 to S29 continuously based on the fact that a predetermined operation indicating the completion of fixing is performed by the worker. .. Further, the operation order of steps S27 to S29 may be changed.

Finally, in step S30, the worker uses the lifting machine 35 to move the work floor 34 to the next bracket mounting position. More specifically, the work floor 34 is raised so that the jig receiver 1 is positioned at the height of the "bracket mounting position" where the bracket 11 corresponding to the rail of the step to be centered next to the guide rail 25 can be mounted. Let me.

Here, since the operations of steps S27 to S29 are performed in advance during the work of step S30, the elevator guide rail centering device 100 mounted on the work floor 34 is free with respect to the guide rail 25 (specifically). The rotation axis and translational slider of the positioning mechanism 2 are not fixed, and the guide rail 25 is not gripped by the jig 3), and the jig 3 also moves with the movement of the work floor 34. You can move along.

Therefore, in the guide rail centering operation using the elevator guide rail centering device 100 according to the present embodiment, after centering the guide rail 25 at a certain stage, the jig 3 is not removed from the jig receiver 1. The work floor 34 can be moved as it is to move to the centering of the guide rail 25 in the next stage, which is expected to have an effect of greatly improving work efficiency.

As described above, according to the elevator guide rail centering device 100 according to the present embodiment, the jig receiver 1 fixed to the plate (or beam, wall) 9 provided in the hoistway 8 and the jig receiver 1 on both sides A positioning mechanism 2 (rotational angle positioning device 13, translational direction positioning device 14, 15) capable of electrically positioning in a plurality of axial directions is provided between the jig 3 that grips the two guide rails 25, and the control device 4 By automatically controlling the positioning mechanism 2, the jig 3 is automatically set to a predetermined relative position from the reference position (position of the piano wire 33) regardless of the position of the beam or the position of the wall in the hoistway 8. Can be positioned. As a result, the bracket 11 can be reliably mounted at an appropriate position based on the positioning result at the bracket mounting position (plate 9) regardless of the position of the beam or the wall in the hoistway 8 other than the bracket mounting position. , The guide rail 25 can be centered. That is, regardless of the position of the beam or the position of the wall in the hoistway 8, the guide rails 25 (rails 25b to 25z) of each stage are automatically positioned while keeping the two guide rails 25 vertically and at a predetermined distance. By moving (raising) the work floor 34 and repeating such work up to the uppermost stage, the guide rail 25 can be sequentially centered with high accuracy.

Further, the elevator guide rail centering device 100 is configured to be mounted on the handrail of the work floor 34 via the joint 12. With this configuration, the joint 12 distributes the weight of the elevator guide rail centering device 100, so that the worker can easily move the elevator guide rail centering device 100 on the work floor 34. Further, since the spring of the joint 12 absorbs the sway, even if the work floor 34 sways in the vertical direction or the front-back and left-right directions due to the movement of the worker or the like, the influence on the jig receiver 1 and the jig 3 can be blocked. .. Thus, even on the work floor 34, which is easily shaken, the guide rail 25 can be centered stably, and the effect of improving work efficiency can be expected.

From the above description, according to the elevator guide rail centering 100 according to the first embodiment, the guide rail 25 is automatically operated with high accuracy regardless of the position of the beam or the position of the wall in the hoistway 8. Positioning can be performed reliably.

(2) Second Embodiment FIG. 9 is a top view of the elevator guide rail centering device according to the second embodiment of the present invention.

(2-1) Structure of Elevator Guide Rail Centering Device 200 The elevator guide rail centering device 200 shown in FIG. 9 is compared with the actuator guide rail centering device 100 (see FIG. 1) according to the first embodiment. At that time, the mechanism for pushing out the backing plate 5 of the jig receiver 1 also serves as the translational direction positioning device 15 in the x-axis direction, and the two linear actuators 160a connected between the jig receiver 1 and the jig 3. , 160b (linear actuator 160) is different in that it also serves as the rotation angle positioning device 13 and the translational direction positioning device 14 in the z-axis direction.

The linear actuator 160 may have the same two-stage structure (see FIG. 4) as the translational direction positioning device 14 described in the first embodiment, but will be described here as a one-stage structure. That is, it is a general linear actuator 160 composed of a linear guide 141, a screw shaft 143, a slider 142, and an actuator 144 (with a brake).

The mechanism for pushing out the backing plate 5 includes linear actuators 160c and 160d (linear actuator 160) having the same structure as described above, and a spring 161. The linear actuators 160c and 160d are attached to both ends of the beam 6 of the jig receiver 1, and the rods 161 of the linear actuators 160c and 160d push out the backing plate 5 via the included spring 162. When the rod 161 is extended and pressed against the plate 9 and the spring 162 is contracted by a predetermined pressing force, the edge of the rod 161 can directly press the backing plate 5 for positioning. Here, a force sensor or a limit switch (not shown) is arranged between the backing plate 5 and the rod 161 to detect that the backing plate 5 comes into contact with the plate 9, and the spring 162 contracts to shrink the rod 161 and the backing plate. A means for detecting the contact of 5 is provided. The uses and purposes of these detection means will be described together with the contents of the installation work described later.

A first pin 163 is provided in the center of the jig 3, and second pins 164a and 164b are provided on the left and right sides of the first pin 163. The jig receiver 1 and the jig 3 are connected by engagement with pins 163 and 164 provided on the jig 3.

A bracket 165 is fixed to the beam 6 of the jig receiver 1 with a bolt 166. The tip of the bracket 165 has a first slot 168 oriented perpendicular to the beam 6 to engage the first pin 163 attached to the center of the jig 3. The jig 3 is restrained in the x direction with respect to the jig receiver 1 by the first elongated hole 168, and when the jig receiver 1 is positioned in the x-axis direction by the linear actuators 160c and 160d, the jig 3 is interlocked with this. Is positioned in the x-axis direction. However, because of the elongated hole shape, the jig 3 can move freely in the z-axis direction at the position of the first pin 163.

On the jig receiver 1, the linear actuators 160a and 160b are fixed to the left and right with the bracket 165 in the direction perpendicular to the jig receiver 1. Second elongated holes 169a and 169b oriented parallel to the jig receiver 1 are attached to the tips of the rods 167a and 167b of the linear actuators 160a and 160b, and the second pins 164a and 164b of the jig 3 are engaged with the second elongated holes 169a and 169b. do. The second elongated holes 169a and 169b constrain the jig 3 at the positions of the second pins 164a and 164b in the z-axis direction.

With such a configuration of the linear actuators 160a and 160b, when the rods 167a and 167b are moved in the same direction by the same amount, the jig 3 translates in the z-axis direction. Further, when the rods 167a and 167b are moved in the opposite directions by the same amount, the jig 3 rotates about the first pin 163 around the y-axis, and the jig 3 is relative to the jig receiver 1 in the vertical axis direction. Twist in. In this way, the relative movements of the linear actuators 160a and 160b allow the jig 3 to be positioned with one translational degree of freedom in the z-axis direction and one rotation degree of freedom around the y-axis with respect to the jig receiver 1.

(2-2) Elevator Guide Rail Installation Work An elevator guide rail installation work using the elevator guide rail centering device 200 according to the second embodiment will be described.

First, the start preparation work before the guide rail centering work is performed by the worker in the same procedure as shown in FIG. 7 in the first embodiment, and thus the description thereof will be omitted.

FIG. 10 is a flowchart showing a procedure example of the guide rail centering work in the second embodiment. Of the operations of each step shown in FIG. 10, the operations of steps S31, S32, S35, and S38 are operations performed by the worker. On the other hand, the work of steps S33, S34, and S37 is a work automatically performed by the elevator guide rail centering device 200 based on an operation by an operator (for example, an operation of an operation button or the like). The work of the other steps is the work regardless of any of the above.

Hereinafter, the procedure of the guide rail centering work in the second embodiment will be described with reference to FIG.

According to FIG. 10, first, in step S31, the worker grips the left and right guide rails 25 using the jig 3. In the first embodiment, the operation button 23 of the jig 3 is operated to electrically grip the guide rail 25, but as in the conventional jig, the worker turns the handle by hand to tighten the hook. May be hooked to grip the guide rail 25. In that case, the jig 3 may be separated from the jig receiver 1 and the linear actuator 160 by removing the bracket 165 of the jig receiver 1 to reduce the load held by the worker.

In the next step S32, the worker uses a spirit level or the like to support the jig 3 so that it is horizontal. Here, the operations of steps S31 and S32 may be performed in parallel. For example, after gripping the guide rail 25 on one side to the jig 3, the jig 3 is supported horizontally and the other guide is maintained in that state. The rail 25 is gripped by the jig 3. When the jig 3 is separated from the jig receiver 1 and the linear actuator 160 and the above operation is performed, the jig 3 is connected to the jig receiver 1 again after the operation.

Next, in step S33, the elevator guide rail centering device 200 fixes the jig receiver 1 to the hoistway 8 (plate 9) based on the operator operating the operation button 7 of the jig receiver 1. The control device 4 drives the linear actuators 160c and 160d attached to the left and right of the jig receiver 1 based on the button operation. When the control device 4 detects that one of the backing plates 5 has come into contact with the hoistway 8 by the sensor described above, the control device 4 stops the linear actuator 160 that has come into contact with the backing path 8, and the other backing plate 5 moves up and down. Only the other linear actuator 160 is driven until it is detected to come into contact with the road 8. This prevents the guide rail 25 from being pushed to the opposite side and deviating from the center when the backing plate 5 on one side first contacts the hoistway 8 when the gap between the hoistway and the left and right of the work floor is uneven. do.

Then, when the control device 4 detects that both the backing plates 5 have come into contact with the hoistway 8, it drives the linear actuators 160c and 160d on both sides again. The control device 4 continues to drive the linear actuators 160c and 160d by the sensor described above until the edges of the rods 161 of the linear actuators 160c and 160d directly hit the backing plate 4. As a result, the backing plate 5 presses the hoistway 8 with a predetermined pressing force (applied by the spring 162), and at the same time, the jig receiver 1 is fixed to the hoistway 8.

In the next step S34, the elevator guide rail centering device 200 positions the guide rail 25 based on the operation of the operation button 23 of the jig 3 by the operator. Similar to the first embodiment, the control device 4 calculates the deviation of the guide rail 25 based on the reference position, and controls the linear actuators 160a to 160d so that the deviation becomes equal to or less than the allowable value.

In the next step S35, the worker attaches the bracket 11 to the bracket attachment position (plate 9) based on the positioning result, and fixes the guide rail 25 to the hoistway 8.

Since centering and fixing of the guide rail 25 are completed in step S35, in the next step S36, the worker removes the jig 3 holding the guide rail 25 from the guide rail 25. At this time, the jig 3 may be separated from the jig receiver 1 and the linear actuator 160, and the jig 3 may be moved to a distant position where it does not come into contact with the left and right guide rails 25.

In the next step S37, all the linear actuators 160 are returned to the home position. Normally, the home position of the linear actuator refers to a position where the amount of movement is zero, but in the present invention, the home position for efficient work is set. For example, for the linear actuators 160c and 160d, the home position may be set at a position where the gap between the hoistway wall surface and the backing plate 5 is 100 mm. Further, for the linear actuators 160a and 160b, the positional relationship between the plate 9 and the guide rail 25 may be determined from the drawing, and a home position may be given so that the jig 1 becomes an ideal position.

Finally, in step S38, the worker moves the work floor to perform the centering work of the next-stage rail by the conventional work floor moving method.

(3) Third Embodiment FIG. 11 is a top view of the elevator guide rail centering device according to the third embodiment of the present invention. The elevator guide rail centering device 300 shown in FIG. 11 is arranged between the jig receiver 1 and the jig 3 when compared with the elevator guide rail centering device 200 (see FIG. 9) according to the second embodiment. The connection methods of the two linear actuators 160a and 160b are different. On the other hand, the mechanism for pushing out the backing plate 5 of the jig receiver 1 also serves as the translational direction positioning device 15 in the x-axis direction, and the two linear actuators 160a connected between the jig receiver 1 and the jig 3. It is the same as the second embodiment in that 160b also serves as the rotation angle positioning device 13 and the translational direction positioning device 14 in the z-axis direction.

According to FIG. 11, two rotary shafts 170a and 170b (rotary shafts 170) are provided on the jig receiver 1, and two linear actuators 160a and 160b are pivotally supported. On the other hand, the linear actuator 160a is provided with a connecting shaft 171a at a predetermined distance from the rotating shaft 170a on the tip side of the rotating shaft 170a. The other linear actuator 160b is provided with a connecting shaft 171b at a predetermined distance from the rotating shaft 170b on the rear end side of the rotating shaft 170b. The two connecting shafts 171a and 171b are connected by a connecting rod 172.

The jig 3 is provided with two rotary shafts 173a and 173b (rotary shafts 173), and is pivotally supported by the tips of the rods 167a and 167b of the linear actuators 160a and 160b. The jig receiver 1, the jig 3, and the two linear actuators 160a and 160b have a four-node link structure, but the connecting rods 172 form a brace and their respective positions are constrained. Therefore, if the linear actuators 160a and 160b are not expanded and contracted, the rotation shafts 170 and 173 do not rotate. Due to the relative movement of the linear actuators 160a and 160b, the shape of the 4-section link changes, the relative positions of the jig receiver 1 and the jig 3 change, and the position of the rotation angle of the jig 3 around the y-axis and the z-axis Positioning in the translational direction of the direction.

FIG. 12 shows the hoistway 8 and the bracket 11 in order to explain the operation of positioning the rotation angle around the vertical y-axis by the elevator guide rail centering device shown in FIG. 11 in the third embodiment. It is the top view which showed the state of the deformation of the 4th section link by omitting the part, and taking out only the apparatus main body part.

With reference to FIG. 12, the operation of the elevator guide rail centering device 300 when the jig 3 is rotated around the y-axis without changing the position of the center point P of the jig 3 will be described. When one linear actuator 160a connected to the jig receiver 1 and the jig 3 is extended and the other linear actuator 160b is contracted, the jig 3 rotates about the y-axis. At this time, as the jig 3 rotates, the rotating shafts 173a and 173b approach the center line 174, so that the two linear actuators 160a and 160b rotate around the rotating shaft 170 so that the tips approach each other. The direction changes. By the action of the connecting rod 172, the linear actuators 160a and 160b rotate on the rotation shafts 170a and 170b with the same amount of rotation (the magnitude of the angle is the same and the direction is opposite). As described above, since there is a structural restriction on the amount of rotation of the linear actuators 160a and 160b on the rotation shaft 170, the center P of the jig 3 moves slightly in the x-axis direction. In order to cancel this, it is necessary to move the linear actuators 160c and 160d attached to the left and right of the jig receiver 1 to correct the position of the jig receiver 1 as a whole in the x direction.

On the other hand, when the jig 3 is translated in the z-axis direction while maintaining the rotation angle of the jig 3 as described above, the target position can be obtained by simply extending or contracting the linear actuators 160a and 160b by the same length. The jig 3 cannot be positioned. Structurally, there is a restriction on the amount of rotation of the linear actuators 160a and 160b on the rotation shaft 170. Therefore, if the lengths of the linear actuators 160a and 160b are different, the linear actuators 160a and 160b are moved from that state. Even if the jig 3 is expanded and contracted by the same length, the center P of the jig 3 moves slightly in the x-axis direction.

From the above, in the elevator guide rail centering device 300, the rotation angle of the jig 3 and the translational direction in the z-axis direction are positioned by the relative operation of the linear actuators 160a, 160b, 160c, 160d. The control device 4 performs a geometric calculation in consideration of the length dimension of each part, and positions the jig 3 at the target x-z coordinate position and the y-axis rotation angle of the linear motion actuators 160a to 160d. Calculate the amount of movement.

The elevator guide rail installation work using the elevator guide rail centering device 300 according to the third embodiment is performed in the same procedure as that shown in FIG. 10 in the second embodiment. , The description is omitted.

As described above, according to the elevator guide rail centering device 200 (or the elevator guide rail centering device 300 according to the third embodiment) according to the second embodiment, the first embodiment. Similar to the elevator guide rail centering device 100 according to the above, the jig 43 is set to a predetermined relative position from the reference position (the position of the piano wire 33) regardless of the position of the beam or the position of the wall in the hoistway 8. , Can be positioned by automatic control. Therefore, the same effect as that obtained by the elevator guide rail centering device 100 according to the first embodiment can be obtained.

Specifically, for example, the elevator guide rail centering device 200 keeps the two guide rails 25 vertically and at a predetermined distance regardless of the position of the beam or the position of the wall in the hoistway 8, and the step of each step. Since the guide rail 25 (rails 25b to 25z) can be automatically positioned, the work floor 34 is moved (raised) and such work is repeated up to the uppermost stage to achieve a highly accurate core of the guide rail 25. It is possible to carry out the delivery in sequence.

Further, for example, the elevator guide rail centering device 200 can be placed on the handrail of the work floor 34 via the joint 12 to block the influence of the shaking of the work floor 34, and even on the work floor 34 which is easily shaken. , The guide rail 25 can be centered stably, and the effect of improving work efficiency can be expected.

From what has been described above, according to the elevator guide rail centering 200 (or the elevator guide rail centering device 300 according to the third embodiment) according to the second embodiment, the beam in the hoistway 8 Regardless of the position of the guide rail or the position of the wall, the guide rail 25 can be reliably automatically positioned with high accuracy.
