Description

  The present invention relates to an elevator rope damping device and a rope damping device mounting structure that suppress rope vibrations.

  In the elevator system, a hoisting machine is installed in a machine room above the hoistway, and a main rope hung on the hoisting machine is suspended in the hoistway through a rope guide port on the machine room floor. A car is suspended from one end of the main rope, and a counterweight is suspended from the other end of the main rope.

  By the way, in recent years, the construction of super high-rise buildings has been on the increase, but the length of the main rope for suspending the car becomes longer as the lifting / lowering stroke of the elevator car becomes higher. On the other hand, if for some reason while the car is running, such as minute vibrations in the hoisting machine, the longer the rope length, the more minute vibration transmitted from the hoisting machine propagates over the entire length of the main rope. Big shaking occurs. As a result, the main rope comes into contact with the equipment in the hoistway or gets caught by the mounting bracket of the equipment in the hoistway. In addition, the swinging of the main rope makes the ride comfort in the car worse, and a room (room) such as a hotel adjacent to the hoistway vibrates or causes noise.

  Therefore, in order to prevent the vibration of the main rope, a rope damping device 100 as shown in FIG. 8 for suppressing the swing of the main rope is attached in the hoistway. In the figure, 101 is a hoisting machine installed in the machine room above the hoistway, 102 is a deflecting sheave, and 103 is a main rope that spans the hoisting machine 101 and the deflecting sheave 102. Both ends of the main rope 103 are dropped into the hoistway through the rope guide port 105 of the machine room floor 104, and the car 106 and the counterweight 107 are suspended. 108a and 108b are guide rails arranged on both sides in the hoistway.

The rope damping device 100 is disposed at the upper part of the hoistway where the ascending travel of the passenger car 106 is prohibited, and a main frame that falls from the rope guide port 105 and a support frame 110 that is laid over the guide rails 108a and 108b. A support member 111 installed on the support frame 110 that is equidistant from 103, and pivotally supported by each support member 111 so as to be able to swing obliquely upward so as to sandwich the main rope 103 Arm 112, a roller 113 that is rotatably attached to the tip of these arms 112 and sandwiches the main rope 103 from both sides, and a spring 114. Each spring 114 is attached between the distal end portion of each arm 112 and the support frame 110 and has a structure in which the main rope 103 is always sandwiched by both rollers 113 to suppress vibration of the main rope 103. (Patent Document 1).
Japanese Utility Model Publication No. 51-146648 (see FIG. 2)

  However, since the rope damping device 100 as described above is installed at a lower position separated from the machine room floor 104 by a predetermined distance, the following problems have been pointed out.

(1) At the time of maintenance and inspection of the rope vibration control device 100, the maintenance staff operates the inspection remote controller while riding on the upper part of the car 106, and while moving the car 106 in the upper part of the hoistway, the rope vibration control is performed. Approach the device 100. However, when the car 106 reaches the ascending travel prohibition area 115 determined by an elevator installation rule or the like, the emergency stop switch operates, and the power is automatically turned off so that the car does not run up. In this state, the maintenance person's hand on the car 106 does not reach the rope vibration control device 100. Therefore, a ladder is installed in advance on the wall of the hoistway, and the maintenance staff moves from the car 106 to the ladder and crawls up, moves to the support frame 110 of the rope vibration control device 100 or the rope vibration control device 100 from the upper stage of the ladder. Maintenance inspection is performed. Therefore, the maintenance and inspection work of the rope vibration control device 100 is very dangerous.

(2) In addition, since the scaffolding for maintenance personnel is in an unstable state, satisfactory maintenance inspection work cannot be performed.

(3) Furthermore, since the rope damping device 100 is installed in the hoistway, it is necessary to newly secure a distance from the machine room floor 104 to the rope damping device 100, and the hoistway is lengthened accordingly. In addition, it is necessary to suppress the height of the machine room above the hoistway, and there is a problem that restrictions on installation of elevator equipment arise.

(4) Further, the rope damping device 100 uses the contraction force of the spring 114 to swing each arm 112 in a predetermined direction, and constantly presses the roller 113 against the main rope 103 with a predetermined pressing force. Since it has a structure, there is a problem that the main rope 103 and the roller 113 are easily damaged.

  The present invention has been made in view of the above circumstances, and can be downsized without impairing the vibration damping performance, can be installed using an appropriate space in the machine room, and can be installed and maintained at a safety during maintenance. It is an object of the present invention to provide an elevator rope damping device and a rope damping device mounting structure to be secured.

  By adopting the configuration as described above, the present invention can reduce not only the height of the rope damping device itself, but also the lateral width, thereby realizing further miniaturization. Therefore, it becomes possible to attach using the appropriate space in the machine room, for example, the appropriate space of the installation structure of the hoisting machine, as in the above (1).

In addition, the rope damping device mounting structure according to the present invention can be mounted on the machine room floor of the machine room by reducing the size of the rope damping device as described above. It becomes possible to improve safety and workability at the time of inspection.

  Further, the rope damping device mounting structure according to the present invention has a damping device mounting bracket attached so as to face each other downward on the lower side of the machine beam installed in parallel in the machine room at a predetermined distance, By attaching the aforementioned rope damping device to these damping device mounting brackets, it becomes possible to improve the workability of attaching the rope damping device and the safety during maintenance.

  Further, the rope damping device mounting structure according to the present invention is orthogonal to the moving direction of the roller that moves when the rope contacts the lower side of the machine beam installed in parallel in the machine room at a predetermined distance. A damping device mounting bracket is attached by a fixing member so as to face each other downward with respect to the long holes of the both machine beams, and the rope control system described above is interposed between the two damping device mounting brackets. By attaching the vibration device, it is possible to improve the workability of attaching the rope vibration control device and the safety during maintenance.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 to FIG. 3 are diagrams for explaining a first embodiment of an elevator rope damping device according to the present invention. FIG. 1 is a configuration diagram of an elevator system including an elevator rope damping device, FIG. 2 is a top view of the rope damping device, and FIG. 3 is a diagram showing details of a damper mounting portion of the rope damping device.

  In these drawings, 1 is a machine room floor at the upper part of a hoistway, 2 is a protrusion (overhang) having, for example, a cross-sectional shape of an arbitrary height projecting on the machine room floor 1 so as to form a square shape, 3 Is a machine beam having a predetermined length, for example, having a cross-sectional shape, disposed in parallel on the protruding portion 2 at a predetermined distance. An anti-vibration stand 5 is disposed on the machine beam 3 via an anti-vibration rubber 4.

  The anti-vibration stand 5 is provided with a hoisting machine 7 connected with a hoisting sheave 6. 8 is a deflected sheave. A plurality of main ropes 9 are stretched over the hoisting sheave 6 and the deflecting sheave 8, and a car 10 that moves up and down in the hoistway is suspended at one end of the main rope 9. A counterweight 11 for balancing the weight with the car 10 is suspended from the section. 12a and 12b are guide rails laid in the vertical direction of the hoistway in order to guide both side portions of the car 10 that moves up and down. A rope guide port 13 is formed in a portion of the machine room floor 1 through which the main rope 9 passes.

  Further, a rope damping device 20 is installed in the space between the machine room floor 1 and the machine beam 3 and in the vicinity of the rope guide port 13 through which the main rope 9 that suspends the car 10 is passed.

  The rope damping device 20 is specifically configured as shown in FIG. The rope damping device 20 has an L-shaped mounting base 21 having a roller mounting surface portion 21a so as to be opposed to a direction orthogonal to the alignment direction of the plurality of main ropes 9 passing through the rope guide port 13 with screws or the like. It is fixed to the machine room floor 1 by attachment means. Two rollers 22 are disposed between the roller mounting surface portions 21a of the mounting base 21 with a substantially equal distance from the aligned main ropes 9. Each roller 22 has a shaft 23 projecting from both ends, and is supported by the mounting base 21 through a long hole 24 (see FIG. 3A) formed in the corresponding roller mounting surface portion 21a. The reason why the long hole 24 is provided in the roller mounting surface portion 21a is that the roller 22 can freely move in a predetermined range in the direction in which the roller 22 can advance and retreat with respect to the main rope 9, that is, in the directions of arrows A and B shown in FIG. This is to make it movable. In FIG. 3, the rope damping device 20 is subject to both upper, lower, left and right, and therefore only a quarter of the rope damping device 20 is illustrated, and the other 3/4 is omitted.

  Further, a reinforcing plate 25 for reinforcing the penetrating portion of each shaft 23 is fixed to the roller mounting surface portion 21a. About the reinforcement board 25, a long hole is formed like the roller attachment surface part 21a, and each axis | shaft 23 can move now.

  A shaft mounting bracket 26 is fixed to the lower end side of each shaft 23 in a direction orthogonal to the longitudinal direction of the shaft 23. A damper 29 such as a hydraulic or pneumatic cylinder is connected between each shaft mounting bracket 26 and a damper mounting bracket 27 fixed to both edges of each mounting base 21 using damper mounting pins 28a and 28b as support shafts. Has been.

Next, operation | movement of the above rope damping devices 20 is demonstrated.
First, the rope damping device 20 is installed not in the upper part in the hoistway as in the prior art, but in the space portion between the machine room floor 1 and the machine beam 3. The reason why it is possible to install in this space portion is that the two rollers 22 can be moved in the horizontal direction through each damper 29 and the shaft mounting bracket 26, so that the height of the rope damping device 20 itself is significantly reduced. This is because, as a whole, the downsizing is realized, so that it is possible to install using an appropriate space portion between the machine room floor 1 and the machine beam 3.

  When the rope damping device 20 does not vibrate the main rope 9, the two rollers 22 are set with a certain margin from the main rope 9, as shown in FIG. 9 is not in contact with the roller 22.

  However, if the main rope 9 exceeds a swinging width in which the main rope 9 is vibrated for some reason, the main rope 9 comes into contact with the roller 22 and a force to push outward acts on the roller 22. At this time, the shaft 23 protruding from the roller 22 also receives a force acting outward. As a result, the shaft 23 moves in the direction A or B in FIG. 3A along the long hole 24 formed in the roller mounting surface portion 21a. At this time, the damper 29 absorbs the force of the main rope 9. The roller 22 is gently moved outward while moving. That is, the damper 29 works to suppress the swing of the main rope 9 while contracting the stroke C shown in FIG.

  Further, when the main rope 9 swings in the opposite direction, the damper 29 returns to the original while extending the stroke C according to the swing of the main rope 9.

  And after the main rope 9 leaves | separates from the roller 22, it contacts with the roller 22 on the opposite side, and the force pushed out toward the outside acts similarly. That is, the damper 29 at the end of each roller 22 suppresses the swing of the main rope 9 by alternately repeating the above-described series of expansion and contraction operations. Therefore, the damper 29 functions to suppress the swing of the main rope 9 and gradually release a large load applied to the main rope 9 when the swing of the main rope 9 by the roller 22 is suppressed.

  Therefore, according to the embodiment as described above, when the two rollers 22 receive a force from the main rope 9, the roller 22 is moved in the horizontal direction while expanding and contracting the damper 29. Therefore, the rope damping device 20 itself Therefore, the overall size can be reduced. This makes it possible to install the rope damping device 20 by effectively using an appropriate space between the machine room floor 1 and the machine beam 3. As a result, the maintenance and inspection in the rope damping device 20 can be performed simultaneously with other equipment in the machine room, and the work can be performed safely because the work is performed in the machine room with good scaffolding. In addition, it is possible to carry out maintenance and inspection work that is sufficiently satisfactory.

  Since the rope damping device 20 is installed using an appropriate space between the machine room floor 1 and the machine beam 3, it does not affect the installation of other elevator equipment.

  In the above-described embodiment, the shaft mounting bracket 26 is fixed to the lower end on the front end side of the shaft 23 mounted on both sides of each roller 22. If a hole is formed, the shaft 22 is rotated by 90 ° according to the wear state of the surface of the roller 22 and then the shaft mounting bracket 26 is screwed using the screw hole at the lower end of the shaft 23. May be.

  With such a configuration, the life of each roller 22 can be greatly extended.

  In the above embodiment, the damper 29 is disposed obliquely rearward from the shaft mounting bracket 26. For example, one side of the mounting base 21 from the shaft 23 or the shaft mounting bracket 26, that is, the same direction as the moving direction of the roller 22 is used. Alternatively, the damper 29 may be arranged.

(Second Embodiment)
FIG. 4 is a view for explaining a second embodiment of the elevator rope damping device according to the present invention, and particularly shows details of a damper mounting portion. The figure (a) is a top view, The figure (b) is a figure when seeing the D arrow direction shown to the figure (a). 4 shows only the left and right sides of the rope damping device 20, and therefore only the damper mounting portion related to the left side of the roller 22 is shown, and the damper mounting portion related to the right side of the roller 22 is omitted. .

  The rope damping device 20 includes two rollers 22a and 22b (hereinafter referred to as a movable transmission path of the rollers) between the roller mounting surface portions 21a of the two mounting bases 21 that face each other as in the first embodiment. (For the sake of clarity, subscripts a and b are added for convenience) and shafts 23a and 23b projecting from both ends of the rollers 22a and 22b are formed in the roller mounting surface portion 21a. It is supported by the mounting base 21 through 24a and 24b. The shafts 23a and 23b projecting from the rollers 22a and 22b are movable in the horizontal direction along the long holes 24a and 24b of the roller mounting surface portion 21a. Each shaft 23a, 23b is shorter than the length of the shaft 23 shown in FIG.

  Bars 31a and 31b are attached to the distal ends of the shafts 23a and 23b so as to extend in the direction of the distal ends of the opposite shafts 23b and 23a and to positions beyond the opposite shafts 23b and 23a. . The front ends of the bars 31a and 31b are bent so as to form an inverted L shape in the opposite direction to the rollers 22a and 22b. Hereinafter, the bent flat surface portions are referred to as roller-side damper mounting bases 32a and 32b. In addition, each roller side damper attachment base 32a, 32b has a vertical positional relationship by making the length of an inverted L-shaped part different. That is, in FIG. 4, the roller side damper mounting base 32a is present at the upper position, the roller side damper mounting base 32b is present at the lower position, and the upper surface of each roller side damper mounting base 32a, 23b is movable on the roller. Transmitters 33a and 33b (33b is hidden below 33a and not shown) are attached.

  On the other hand, base-side damper mounting brackets 34a and 34b whose front ends are erected so as to form a flat portion of a predetermined height on the mounting base 21 opposite to the rollers 22 with the bars 31a and 31b interposed therebetween. Is installed. Dampers 35a and 35b (35b is hidden under 35a) so as to come into contact with the roller movable transmission elements 33a and 33b on the roller side damper mounting bases 32a and 32b from the flat portions of the base side damper mounting brackets 34a and 34b. (Not shown) is provided.

  In such a configuration, when the main rope 9 exceeds the sway width in which the main rope 9 is vibrated for some reason, for example, when the main rope 9 comes into contact with the roller 22a, the force to push outward is applied to the roller 22a. Works. At this time, the shaft 23a protruding from the roller 22a also receives a force acting outward. As a result, the shaft 23a moves along the long hole 24a of the roller mounting surface portion 21a. When the shaft 23a moves outward along the long hole 24a, the bar 31a, the roller-side damper mounting base 32a, and the roller movable transmission element 33a also move horizontally together, so that the damper 35a is pressed by the roller movable transmission element 33a. The As a result, the damper 35a gently moves the roller 22a outward while absorbing the force received from the main rope 9. That is, the damper 35a works in a direction to suppress the swing width of the main rope 9 while contracting. Further, when the main rope 9 swings in the opposite inner direction, the damper 35a works so as to return to the original while extending according to the swing of the main rope 9.

  Further, when the main rope 9 comes into contact with the roller 22b, the damper 35b existing just below the damper 35a expands and contracts similarly to the case where it comes into contact with the roller 22a, and performs the same function as the damper 35a.

  Therefore, in this embodiment, the dampers 35a and 35b are arranged on the mounting base 21 so as to overlap each other, and the dampers 35a and 35b extend and contract in the same direction as the moving direction of the rollers 22a and 22b. Therefore, the lateral width of the rope damping device 20 can be shortened and further reduced in size as compared with the structure in which the damper 29 is disposed in the obliquely rearward direction shown in FIG.

(Third embodiment)
5A and 5B are diagrams for explaining the attachment structure of the rope vibration control device according to the present invention. FIG. 5A is a front view, and FIG. 5B is a side view.
In the first and second embodiments, the description has been made on the premise that the downsized rope damping device 20 is attached to the machine room floor 1. However, in this embodiment, at least a predetermined distance as shown in FIG. For example, a vibration control device mounting bracket 41 having an L-shaped cross section facing each other downward is attached to the lower side of the two machine beams 3 arranged in parallel with each other, and the above-described FIG. Or the rope damping device 20 shown in FIG. 4 is attached by welding or the like.

  According to this embodiment, the rope damping device 20 shown in FIG. 2 or FIG. 4 is miniaturized, so that the two damping device mounting brackets 41 attached to the lower side of the two machine beams 3 are attached to the rope damping device 41. The vibration control device 20 can be attached, and the rope vibration control device 20 can be attached with excellent performance. Also, the rope vibration control device 20 can be maintained and inspected in the machine room, and safety during maintenance inspection can be ensured. .

(Fourth embodiment)
Next, another embodiment of the rope damping device mounting structure according to the present invention will be described.

  In the third embodiment shown in FIG. 5 described above, the damping device mounting bracket 41 having an L-shaped cross section is attached to the lower side of the machine beam 3 in the machine room at the installation site so as to face each other downward. The rope damping device 20 is attached to the damping device mounting bracket 41 by welding or the like. However, this attachment structure has a remarkably narrow range for adjusting the relative position between the rope guide port 13 and the rope damping device 20 caused by a construction error occurring at the installation site.

  Accordingly, in this embodiment, a slightly wide and long slot is formed in a portion corresponding to the attachment of the rope damping device 20 on the lower side of the machine beam 3 before being brought into the machine room in advance, and then loaded into the machine room. To do. Then, the rear end side of the damping device mounting bracket 41 having an L-shaped cross section for fixing the rope damping device 20 is set to a long hole portion formed on the lower side of the machine beam 3. At this time, when a relative error occurs between the rope guide port 13 and the rope vibration control device 20 due to a construction error or the like, the vibration control device mounting bracket 41 of the vibration control device mounting bracket 41 is formed along the long hole formed on the lower side of the machine beam 3. The position of the bolt hole is moved, the relative positions of the plurality of main ropes 9 and eventually the rope guide port 13 and the two rollers 22 or 22a and 22b of the rope damping device 20 are determined, and the machine beam 3 is bolted and nuted. The damping device mounting bracket 41 is tightened and fixed using

  Thereby, the adjustment range at the time of the construction adjustment of the rope vibration control device 20 is improved, and the rope vibration control device 20 is flexibly aligned and attached to the misalignment of the main rope 9 caused by a construction error. be able to.

(Fifth embodiment)
FIG. 6 is a view showing the details of the rope damping device mounting portion for explaining another embodiment of the rope damping device mounting structure according to the present invention.

  In the above-described fourth embodiment, the size, shape and position of the long hole for mounting the vibration damping device mounting bracket 41 must be determined at the design stage of the machine beam 3, and the rope vibration damping device. The machine beam 3 cannot be shared between the elevator system including the elevator system 20 and the elevator system not including the rope damping device 20. That is, the machine beam 3 used in the elevator system including the rope damping device 20 is treated as a custom-made product, and various inconvenient aspects appear.

  Therefore, in the present embodiment, as shown in FIG. 6, the damping device mounting bracket 41 for mounting the rope damping device 20 is orthogonal to the end of the rope damping device 20 on the side opposite to the rope damping device 20, that is, the right end of the drawing. A long hole 42 is formed in the depth direction of the drawing. The rail clip 43 is meshed with the lower outer edge of the machine beam 3 having a cross-sectional shape and is fastened and fixed with a bolt 44 and a nut 45. 46 is a spacer.

  The rope damping device 20 has a mounting structure in which the bolt 44 is inserted into the rail clip 43 and the long hole 42 of the damping device mounting bracket 41 and temporarily tightened with the bolt 45, and then the rope guide port 13 and the rope damping device 20. When the optimum mounting position is determined, the bolt 44 and the nut 45 are tightened and fixed.

  When the vibration control device mounting bracket 41 is positioned and fixed, and a normal machine beam fixing bolt hole is opened in the lower inner flat portion of the machine beam 3, the bolt hole is used, and the bolt 44 and nut 45 are used. Then, the opposite side of the vibration damping device mounting bracket 41 is fastened and fixed to the machine beam 3. A long hole is formed in the portion corresponding to the bolt hole of the vibration damping device mounting bracket 41 in the same manner as the long hole 42. When the machine beam 3 has no bolt hole, an appropriate portion of the boundary portion between the lower inner flat portion of the machine beam 3 and the vibration damping device mounting bracket 41 is welded 48 and is completely fixed.

  Therefore, in the embodiment as described above, the long hole 42 required for the vibration damping device mounting bracket 41 is processed, but the processing on the machine beam 3 side can be completely eliminated. The adjustment range is expanded beyond the long holes of the embodiment, and the consistency of design and on-site installation can be significantly improved.

(Sixth embodiment)
In the third to fifth embodiments described above, a damping device mounting bracket 41 having an L-shaped cross section is attached to the lower side of the machine beam 3 so as to face downward, and a rope is provided between these damping device mounting brackets 41. This is a structure to which a vibration damping device 20 is attached. In this case, the rope damping device 20 is disposed in the space portion between the lower portion of the second machine beam 3 and the machine room floor 1, that is, the space portion corresponding to the height of the protruding portion 2. Is low, the margin in the height direction between the lower part of the machine beam 3 and the machine room floor 1 is also reduced accordingly. As a result, a state in which the rope damping device 20 and the machine room floor 1 interfere with each other occurs, and the rope damping device 20 cannot be attached.

  Therefore, in the present embodiment, as shown in FIG. 7, damping device mounting brackets 41 having an L-shaped cross section are attached so as to face upward from the lower side of the machine beam 3, and between these damping device mounting brackets 41. The rope damping device 20 is attached.

  According to this embodiment, the protruding portion (overhang) 2 from the machine room floor 1 can be eliminated as necessary, and there is a margin in the height direction between the machine beam 3 and the machine room floor 1. Regardless, the rope vibration control device 20 can be attached.

  In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
