Description

  The present invention relates to an elevator wiring structure formed in an elevator.

  BACKGROUND Conventionally, elevators for transporting people and luggage are provided. Such an elevator is a car unit that moves in a hoistway provided in a building, and includes a car unit movable to each position corresponding to each of a plurality of halls provided at intervals in the building.

  Each landing includes a landing that communicates with the inside of the hoistway, and a landing door that opens and closes the landing. The car unit includes a car body in which an entrance is formed, and a car door that opens and closes the entrance. In the elevator, the car door and the landing door facing the car door are interlocked and opened / closed in a state where the car unit is stopped at the position corresponding to one landing.

  Therefore, in the elevator, after the car unit moves to a predetermined landing and stops at a position where the car door and the landing door face each other, when the landing door is opened together with the car door, the entrance of the car body and the landing opening communicate with each other. It is possible for people and luggage to move between the car body and the landing.

  By the way, the wiring structure which has the cable extended from various apparatuses may be formed in the above-mentioned elevators. For example, in an elevator where a sensor (a switch, a detection sensor, etc.) for detecting the presence or absence of a person or a load passing through the entrance of the car body is installed in the car unit, the elevator extends from the car door and A wiring structure having a cable disposed on the outer surface is formed (see, for example, Patent Document 1)

  The cable extending from the detector is connected to another cable extending from a device such as a power supply or removed from the other cable. Therefore, the cable extending from the detector is disposed on the outer surface of the car door in a state where the cable is slackened in advance.

  As described above, in the above-described wiring structure, since the cable disposed on the outer surface of the car door has slack, it is possible to drive the elevator (e.g., raising and lowering the car unit, opening and closing the car door, etc.) As a result, the cable may be separated from the outer surface of the car door, and the cable may be damaged by coming into contact with equipment installed in the hoistway. Such problems may also occur when the cable is disposed on the outer surface of the car body, at the landing door, in the hoistway or the like.

Further, the elevator 1 is provided with a plurality of landings 4 provided at intervals in the building, the landing 4 communicating with the hoistway 3 and having a landing door 40 for opening and closing the landing openings. . Note that only one landing 4 is shown in FIG. 1 for the sake of convenience.

  The car unit 2 includes a car body 20 in which an entrance (not numbered) is formed, and a car door 21 for opening and closing the entrance. Further, in the car unit 2, the pair of car doors 21 are arranged in one direction. Each car door 21 slides in one direction.

  In the car unit 2, the car doors 21 slide in one direction so as to move toward and away from each other, thereby switching between the state where the entrance is closed by each car door 21 and the state where each car door 21 opens the entrance Be That is, the elevator 1 which concerns on this embodiment is a center open type. In the present embodiment, the following description may be made with the direction in which each car door 21 slides as the opening / closing direction. Further, in the present embodiment, an operation in which the car doors 21 slide in a direction toward each other is referred to as a closing operation, and an operation in which the car doors 21 slide in a direction away from each other may be described as an opening operation. .

It will be described more specifically. The connection line 222 is disposed along the outer surface of the car door 21 in a state where the base end is disposed below the car door 21 and the tip end is disposed above the car door 21. Furthermore, the connection line 222 has a slack on the tip end side so that the connection work to the control device 23 (the trunk line 231 of the control device 23) and the removal work from the control device 23 can be performed. It is disposed on the outer surface of the car door 21 in the closed state.

  The control device 23 includes a control unit main body 230 installed above the car main body 20, and a trunk line 231 having a base end connected to the control unit main body 230 and a tip opposite to the base end.

  As shown in FIGS. 2 and 5, the trunk line 231 has a wiring member 231a having a base end connected to the control unit body 230 and a tip opposite to the base end portion, and a tip of the wiring member 231a. And a connection connector 231b to be attached. In the present embodiment, one trunk line 231 has a plurality of wiring members 231a and a plurality of connection connectors 231b individually attached to the plurality of wiring members 231a. The trunk line 231 according to the present embodiment is prevented from swinging in a direction orthogonal to the vertical direction and the opening / closing direction. More specifically, the cable chain is attached to the trunk line 231. Further, the control device 23 according to the present embodiment includes a pair of trunk lines 231.

  In the car unit 2 according to the present embodiment, the detection device 22 and the control device 23 are electrically connected by connecting the connection connector 222 b of the connection line 222 and the connection connector 231 b of the trunk line 231 to each other. Thus, the control unit body 230 is configured to be able to receive the signal transmitted from the detection switch 221 via the connection line 222 and the trunk line 231.

  Then, when the control unit main body 230 receives the signal transmitted from the detection switch 221, for example, the sliding of the car door 21 in the closing operation is stopped or the operation of the car door 21 in the closing operation is switched to the opening operation. Configured to

  The wiring structure according to the present embodiment is formed in an elevator having a pair of opposing surface portions that can move relative to each other in directions orthogonal to each other and to each other.

  It will be described more specifically. The wiring structure is, as shown in FIG. 2, a cover member 6 which covers a connecting portion to another cable 5 in the cable 5 disposed along one of the pair of facing surface portions, and the cover member 6 The cable 5 is provided with a cable tensioning mechanism 7 capable of adjusting the slack of the cable 5 formed in the vicinity of the cover member 6 by tensioning the cable 5. In the present embodiment, the following description may be made with the direction in which the pair of facing surface portions face each other as the facing direction.

  In the present embodiment, the following description will be made on the premise that the connecting portion with the trunk line 231 in the connecting line 222 disposed on the outer surface of the car door 21 is covered with the cover member 6. Therefore, the one opposing surface portion in the present embodiment is the outer surface of the car door 21, and the other opposing surface portion of the pair of opposing surface portions is in operation of the elevator 1 (for example, in the car unit 2) At the time of lifting and lowering, opening and closing operation of the car door 21, etc., the hoistway 3 passing the outer surface of the car door 21, equipment installed in the hoistway 3, and the landing door 40 and the like.

  Further, in the present embodiment, the cable 5 is a connection line 222 of the detection device 22, and the other cable 5 is a trunk 231 of the control device 23. Therefore, the cover member 6 covers the connection connector 222 b of the connection wire 222 and the connection connector 231 b of the trunk line 231. In the present embodiment, the connecting wire 222 (cable 5) is used as the first cable 5, and the trunk line 231 (the other cable 5) is used as the second cable 5, and the slack of only the first cable 5 is suppressed. The following explanation will be given as a premise.

  As shown in FIG. 3, the cover member 6 is disposed between a pair of facing surfaces (between the outer surface of the car door 21 and the outer surface of the car door 21 passing the elevator 1 during driving). A protective member 60 is provided.

  The protective member 60 includes a protective wall 600 aligned with the one opposing surface via the first cable 5 and the second cable 5, and an attachment 601 for attaching the protective wall 600 to the one opposing surface. Have.

  Further, the protective member 60 has a covering portion 602 which extends from the protective wall portion 600 toward the one facing surface portion and covers the upper side of the first cable 5 held by the protective wall portion 600. The protection member 60 extends from the protection wall 600 toward the one facing surface portion, and is disposed below the first cable 5 and the second cable 5 held by the protection wall 600. Have.

  The protective wall portion 600 has a plurality of through holes 604 penetrating in the opposite direction. Therefore, in the protective member 60, the first cable 5 can be fixed to the protective wall 600 by the strip B inserted into the through hole 604 (see FIGS. 4 and 5). In addition, since the first cable 5 and the second cable 5 are disposed between the protective wall portion 600 and the one opposing surface portion, the first cable 5 and the second cable are separated from the other opposing surface portion. 5 can be protected.

  The attachment portion 601 extends from the upper end of the protective wall portion 600 toward the one facing surface portion. Further, the mounting portion 601 extends from the entire length of the upper end of the protective wall portion 600 toward the one facing surface portion. Therefore, in the present embodiment, the mounting portion 601 also serves as the covering portion 602.

  As shown in FIGS. 6 (a), 6 (b) and 6 (c), the attachment portion 601 is rotatably attached to the one facing surface portion. It will be described more specifically. The mounting portion 601 has an elongated hole 601 a penetrating in the vertical direction. Further, the mounting portion 601 has a lock hole 601 b formed at an interval from the long hole 601 a in the direction along the upper end of the protective wall portion 600.

  In the long hole 601 a, the hole diameter in the direction along the upper end of the protective wall portion 600 (the opposite direction) is larger than the hole diameter in the direction in which the attachment portion 601 extends from the upper end of the protective wall portion 600. In the present embodiment, the mounting portion 601 is rotatably mounted on the one facing surface portion by a bolt S inserted into the long hole 601 a of the mounting portion 601. Therefore, the protective member 60 is rotatable around the axis of the bolt S inserted into the elongated hole 601 a and is also movable in the direction along the upper end of the protective wall 600.

  The lock hole 601 b is formed in a wedge shape opened at the tip of the attachment portion 601 (the end opposite to the end connected to the protective wall 600). It will be described more specifically. The lock hole 601b is a guide groove 601c formed from the tip of the attachment portion 601 toward the base end of the attachment portion 601, and a slide groove 601d continuous with the guide groove 601c and extending in the direction along the upper end of the protective wall 600. And.

  Therefore, by rotating the mounting portion 601, the bolt S can be guided from the guide groove 601c into the slide groove 601d, and further, by moving the mounting portion 601 in the direction along the upper end of the protective wall portion 600, The bolt S is prevented from coming off the slide groove 601d.

  As described above, the cover member 6 holds the first cable 5 of the first cable 5 and the second cable 5 connected to each other by the protective member 60 (protective wall 600). . Therefore, as shown in FIG. 3, the cover member 6 has a holding stand 61 for holding the second cable 5 to be connected to the first cable 5 disposed on the one facing surface portion.

  The holding base 61 has a fixing plate portion 610 attached to the protective wall portion 600 and an extending plate portion 611 extending from the fixing plate portion 610 toward the one facing surface portion. The extension plate portion 611 has a plurality of insertion holes 611 a penetrating in the plane orthogonal direction.

  Therefore, in the holding stand 61, the second cable 5 can be fixed to the fixing plate portion 610 by the band-like material B inserted into the insertion hole 611a.

  The cable stretching mechanism 7 can change the holding position of the first cable 5 by the cover member 6 in the direction orthogonal to the opposite direction. As described above, in the cover member 6 according to the present embodiment, the attachment position of the protection member 60 holding the first cable 5 to the one facing surface portion is changed by the elongated hole 601 a and the lock hole 601 b of the attachment portion 601. Is configured. Therefore, in the wiring structure according to the present embodiment, the cover member 6 doubles as the cable tensioning mechanism 7.

  The wiring structure according to the present embodiment is as described above. Subsequently, how to stretch the cable 5 (in the present embodiment, the first cable 5) in the wiring structure according to the present embodiment will be described with reference to the attached drawings.

  Prior to the description of how to stretch the first cable 5 in the wiring structure, first, the method of arranging the first cable 5 will be described. The first cable 5 (connection line 222 connected to the detection switch 221) is fixed to the outer surface of the car door 21 in order from the base end side to the tip end side. At this time, the first cable 5 is fixed to the outer surface of the car door 21 in a state where the tip end side is slackened.

  Then, by rotating the cover member 6 (protective member 60) in the circumferential direction about the hole center of the elongated hole 601a, the protective wall portion 600 is inclined to the one facing surface portion. Thus, the first cable 5 can be fixed to the protective wall 600. Then, the first cable 5 is fixed to the protective wall 600 by the strip B. Furthermore, the connection connector 222 b of the first cable 5 and the connection connector 231 b of the second cable 5 are connected to each other.

  After this, by rotating the cover member 6 (protective member 60) in the circumferential direction about the hole center of the elongated hole 601a, the protective wall portion 600 is made to face the one facing surface portion. At this time, the bolt S inserted through the one facing surface portion is disposed in the slide groove 601 d through the guide groove 601 c of the mounting portion 601.

  Then, as shown in FIG. 7, when the cover member 6 (protective member 60) is moved in the direction along the upper end of the protective wall 600 (the opposite direction), the first cable fixed to the protective wall 600 By pulling 5 in the direction in which the cover member 6 is moved, the slack of the first cable 5 is suppressed. That is, the first cable 5 is pulled by moving the cover member 6 in a direction away from the portion fixed to one of the facing surfaces (the outer surface of the car door 21) of the first cable 5.

  As described above, when the cover member 6 (protective member 60) is moved in the direction along the upper end of the protective wall 600, the portion where the first cable 5 is fixed to the protective wall 600 and the one opposing surface portion The distance from the portion fixing the first cable 5 is increased, and the slack of the first cable 5 is suppressed.

  In the wiring structure, if the slack of the first cable 5 can be suppressed, tension may be generated in the first cable 5 that has been pulled, and no tension is generated in the first cable 5 that has been pulled. It is also good. However, when tension is generated in the pulled first cable 5, it is possible to more reliably suppress the first cable 5 from being separated from the one opposing surface when the one opposing surface moves. .

  As described above, the wiring structure according to the present embodiment includes the cable stretching mechanism 7 capable of adjusting the slack of the first cable 5 formed in the vicinity of the cover member 6 by stretching the first cable 5. When the first cable 5 is tensioned by the cable tensioning mechanism 7, the first cable 5 is restrained from loosening and becomes difficult to separate from the outer surface of the car door 21 which is the one opposing surface portion.

  In the wiring structure according to the present embodiment, the cover member 6 for holding the first cable 5 disposed on the one facing surface also serves as the cable tensioning mechanism 7, and the cover member 6 further faces the one facing The mounting position with respect to the surface portion can be changed.

  Therefore, in the wiring structure according to the present embodiment, when the mounting position of the cover member 6 with respect to the one facing surface portion is changed, the holding position of the first cable 5 is also changed. As a result, since the first cable 5 is stretched, the slack of the first cable 5 is suppressed and it becomes difficult for the first cable 5 to be separated from the outer surface of the car door 21 which is the one opposing surface portion.

  Therefore, the first cable 5 is separated from the one opposing surface portion even if the pair of opposing surface portions move relative to each other along with the driving of the elevator (lifting operation of the car unit 2 and opening / closing operation of the car door 21). Can be reduced. Thereby, the first cable 5 disposed on the outer surface of the car door 21 which is the one opposing surface portion is the other opposing surface portion (the hoistway 3, the equipment installed in the hoistway 3, the landing, The door 40 and the like are prevented from coming into contact and breaking.

  In addition, the protection member 60 of the cover member 6 is in the closed state inaccessible to the first cable 5 from the open state accessible to the first cable 5 held between the cover member 6 and the opposite surface portion. The first cable 5 is configured to be able to be pulled in a switched state.

  Therefore, in the closed state, the protective member 60 of the cover member 6 can be prevented from being separated from the one facing surface portion by restricting the movement of the first cable 5, and in the open state, the first member By releasing the restriction on the movement of the cable 5, the connection to the second cable 5 and the removal from the second cable 5 can be performed. In addition, the protection member 60 of the cover member 6 prevents the first cable 5 from blocking the rotation of the protection member 60 by preventing the first cable 5 from being stretched while the protection member 60 is in the open state. It can also be prevented.

  Further, by rotating the protective wall 600, the protective member 60 inclines the posture of the protective wall 600 with respect to the posture (closed state) facing the one facing surface and the one facing surface. Since it can be switched to the posture (open state), the work on the first cable 5 can be performed while the protective wall 600 is attached to the one facing surface. Therefore, the protective member 60 is prevented from falling off when performing the work on the first cable 5.

  Then, in the protective member 60, the covering portion 602 (attachment portion 601) covers the upper end of the first cable 5 held by the protective wall portion 600 and the tip end portion of the second cable 5. The first cable 5 and the second cable 5 can be protected from raindrops and dust falling from above.

  The wiring structure according to the present invention is not limited to the above embodiment, and it goes without saying that various changes can be made without departing from the scope of the present invention.

  In the said embodiment, although one said opposing surface part was an outer surface of the cage door 21, it is not limited to this structure. For example, the one opposing surface may be the outer surface of the car body or the inner surface of the hoistway. Further, each of the pair of opposing surface portions may be configured to move only one of the one opposing surface portion and the other opposing surface portion, as long as they can move relative to each other. Both the one opposing surface portion and the other opposing surface portion may be configured to be movable.

  That is, in the above embodiment, the wiring structure is premised on suppressing the slack of the first cable 5 disposed on the outer surface of the car door 21 of the car unit 2, but the present invention is not limited to this configuration. For example, the wiring structure may suppress the slack of the first cable 5 disposed on the outer surface of the car body 20 of the car unit 2.

  Further, the wiring structure may suppress the slack of the first cable 5 disposed on the inner surface of the landing door 40, the inner surface of the hoistway 3 or the like. In this case, the cover member 6 may be attached to the inner surface of the landing door 40, the inner surface of the hoistway 3, or the like.

  In the above embodiment, the cable tensioning mechanism 7 is capable of changing the mounting position of the cover member 6 with respect to the one facing surface in the direction along the upper end of the protective wall 600, but is not limited to this configuration. For example, the cable tensioning mechanism 7 may change the mounting position of the cover member 6 with respect to the one opposing surface in the vertical direction.

  That is, if the cable tensioning mechanism 7 can suppress the slack of the first cable 5, the cable tensioning mechanism 7 with respect to the one opposing surface portion of the cover member 6 in any one of the directions in which the outer surface of the one opposing surface portion spreads. The mounting position may be changeable.

  In the said embodiment, although the cable tensioning mechanism 7 was comprised so that the 1st cable 5 could be tensioned by making the attachment position of the cover member 6 changeable, it is not limited to this structure. For example, the cable laying mechanism 7 may move the first cable 5 itself relative to the protective member 60. In this case, as shown in FIG. 8, a strip B attached to the first cable 5 is formed with a movable hole 605 extending in one direction (direction along the upper end of the protective wall 600) with respect to the protective wall 600. Can be fixed at each position of the movable hole 605.

  In the above embodiment, the cable laying mechanism 7 is configured to stretch the first cable 5 by changing the holding position of the first cable 5, but the present invention is not limited to this configuration. For example, as shown in FIG. 9, the cable tensioning mechanism 7 may include a pressing member 70 that presses the first cable 5 held by the cover member 6.

  The pressing member 70 has, for example, a pressing portion 700 extending in one direction, and a shaft member 701 that rotatably connects the pressing portion 700 to the protective wall portion 600. The shaft member 701 is arranged such that the axial direction corresponds to the surface orthogonal direction of the protective wall 600.

  Therefore, the pressing member 70 can press the first cable 5 with the pressing portion 700 by bringing the pressing portion 700 rotated about the axis of the shaft member 701 into contact with the first cable 5. . As a result, the first cable 5 is pulled in the direction in which it is pressed by the pushing portion 700, so that the slack of the first cable 5 is suppressed.

  In the above embodiment, the cable laying mechanism 7 is configured to stretch the first cable 5 by changing the holding position of the first cable 5, but the present invention is not limited to this configuration. For example, as shown in FIG. 10, the cable laying mechanism 7 may include a pull-in member 71 that pulls in the cable 5 whose end is held by the cover member 6. The pull-in member 71 has, for example, a rotating portion 710 capable of holding the first cable 5, and a rotating shaft 711 rotatably connecting the rotating portion 710 to the protective wall portion 600.

  Therefore, when the pull-in member 71 rotates the rotating portion 710 holding the first cable 5 around the axis of the rotating shaft 711, the first cable 5 is pulled in by the rotating portion 710, whereby the first cable 5 is pulled in. The slack of the first cable 5 is suppressed. In this case, the first cable 5 may be fixed to the outer peripheral edge of the rotating portion 710 by a strip B inserted through an insertion hole 710 a formed in the rotating portion 710.

  Thus, the cable tensioning mechanism 7 only has to be capable of tensioning the first cable 5 in the length direction. Also, the cable tensioning mechanism 7 may be configured by the cover member 6 or may be configured separately from the cover member 6.

  In this case, the protective member 60 may have a lock portion 606 for maintaining a state in which the protective wall portion 600 and the one facing surface portion are opposed to each other. The lock portion 606 shown in FIG. 11 has an extension piece 606a extending from the protective wall portion 600 toward the one facing surface portion, and a concave notch 606b formed in the extension piece 606a.

  Then, by rotating the protective wall portion 600, the extension piece 606a of the lock portion 606 can be made to pass through the concave portion 210 formed in the car door 21, and the protective wall portion 600 can be in the opposite direction. By sliding in a direction orthogonal to the direction, a part of the car door 21 can be passed through the notch 606b. Therefore, by hooking the lock portion 606 to the car door 21, the protective wall portion 600 can be maintained in the state of facing the car door 21.

  In the above embodiment, the first cable 5 is arranged to extend from one end side of the cover member 6 in the opening and closing direction, and the second cable 5 is arranged to extend from the other end side of the cover member 6 in the opening and closing direction. However, for example, as shown in FIG. 12, each of the first cable 5 and the second cable 5 may be arranged to extend from one end side in the opening and closing direction of the cover member 6.

  In this way, by moving the protective member 60 in the direction along the upper end of the protective wall 600, the slack of the first cable 5 and the second cable 5 can be suppressed. Thus, the wiring structure may be configured to suppress slack of each of the pair of cables 5 (first cable 5 and second cable 5) connected to each other.
