[0005] In Patent Document 1, one end of the lead wire, i.e., the control cable, is connected to a junction box fixed inside the shaft. Although not described in Patent Document 1, there are cases where other equipment is installed below the junction box. In this case, since the control cable passes through the front of the equipment located below the junction box, it presents the problem of difficulty in performing maintenance work on that equipment.

[0030] Implementation method 1.

[0031] Figure 1 This is a side view showing an example of an elevator installation. Figure 2 It is Figure 1 A magnified side view of a portion of the image. Figure 3 From Figure 2 The main view is viewed in the direction of arrow A in the image.

[0032] like Figure 1As shown, the elevator unit 1 includes a position adjustment device 3 capable of adjusting the position of the control cable 2, a car 5, and a counterweight 6. The car 5 moves up and down in the hoistway 7. The counterweight 6 moves up and down in the hoistway 7 in the opposite direction to the direction of movement of the car 5. The car 5 and the counterweight 6 are suspended in the hoistway 7 by means of a flexible elongated body 8. The elongated body 8 can be, for example, rope-shaped or strip-shaped.

[0033] The traction machine 9 is a device used to drive the car 5. A long strip 8 is wound around the main sheave 10 and the deflector sheave 11 of the traction machine 9. Although not shown in the figure, the traction machine 9 includes: a motor that rotates the main sheave 10; an encoder, such as a resolver, that outputs a signal corresponding to the rotation angle of the main sheave 10; and a braking device for keeping the main sheave 10 stationary.

[0034] The traction machine 9 is controlled by the control device 14. That is, the movement of the car 5 is controlled by the control device 14. Figure 1 An example is shown where the traction machine 9 and control device 14 are located in a machine room 16 above the shaft 7. The traction machine 9 and control device 14 can also be located in the shaft 7. When the traction machine 9 is located in the shaft 7, the traction machine 9 can be located at the top of the shaft 7 or at the bottom of the shaft 7.

[0035] like Figure 3 As shown, track 17 guides the movement of car 5. Figure 1 and Figure 2 The illustration of track 17 is omitted in the text. (See example...) Figure 1 As shown, a first device 18 is fixed in the shaft 7. The first device 18 may be installed, for example, on the track 17, on the wall of the shaft 7, or on the beams or columns of the building.

[0036] The first device 18 is electrically connected to the control device 14 via cable 19. The first device 18 may also be a device commonly referred to as a relay box. The first device 18 is not limited to a relay box. When the control device 14 is located in the shaft 7, the control device 14 may also be configured as the first device 18. That is, the control device 14 may also be equivalent to the first device 18.

[0037] The control cable 2 has a first end 20 connected to the first device 18 and a second end 21 connected to the car 5. The control cable 2 may also have at least one conductor (such as a power line or control line), at least one cable, and a sheath covering the conductor and cable. The control cable 2 is also referred to as a lead wire or traveling cable. The control cable 2 in the illustrated example is a flat cable with a flat cross-sectional shape. Not limited to the illustrated example, the control cable 2 may also have a circular cross-sectional shape, for example.

[0038] The control cable 2 is suspended between the first end 20 and the second end 21 by its own weight. The lowest part of the control cable 2 is bent into a U-shape. When the car 5 rises, the length of the portion of the control cable 2 hanging from the first end 20 shortens, and the length of the portion hanging from the second end 21 lengthens. When the car 5 descends, the length of the portion of the control cable 2 hanging from the first end 20 lengthens, and the length of the portion hanging from the second end 21 shortens.

[0039] At the first end 20, the cable of the control cable 2 may be connected to the suspension part located at the lower part of the first device 18, and the conductor of the control cable 2 may be electrically connected to the first device 18. At the second end 21, the cable of the control cable 2 may be connected to the suspension part located at the lower part of the car 5, and the conductor of the control cable 2 may be electrically connected to the car 5.

[0040] exist Figure 1 In this example, the car 5 is electrically connected to the control device 14 via control cable 2, first device 18, and cable 19. The equipment in the car 5 is controlled by the control device 14.

[0041] In the shaft 7, the second device 23 is fixed at a position lower than the first device 18. The second device 23 is located vertically below the first device 18. The second device 23 is adjacent to the portion of the control cable 2 that hangs down from the first end 20. The second device 23 may also have at least one of, for example, a transformer for voltage transformation, a control panel for operation management, and a backup power supply device in case of power failure.

[0042] exist Figure 3 In this example, the second device 23 is mounted on the track 17 via a bracket 24. As a variation, the second device 23 may be mounted on the wall of the shaft 7, or on a beam or column of a building. Figure 3 In this example, the control cable 2 passes vertically through the front of the housing of the second device 23, which serves as its outer contour. When the car 5 reaches the height position of the second device 23, the front of the housing of the second device 23 faces the car 5.

[0043] The position adjustment device 3 includes an upper vibration damper 25 positioned above the second device 23 and a lower vibration damper 26 positioned below the second device 23. Figure 3 In this example, the upper vibration damper 25 and the lower vibration damper 26 are respectively installed on the track 17. As a variation, the upper vibration damper 25 and the lower vibration damper 26 can be installed on the wall of the shaft 7, or on the beams or columns of the building.

[0044] In the illustrated example, the upper vibration damper 25 is positioned above the upper end of the second device 23. Furthermore, the lower vibration damper 26 is positioned below the lower end of the second device 23.

[0045] exist Figure 2 and Figure 3 In this example, a handrail 27 is provided above the car 5. The handrail 27 is positioned so that maintenance personnel climbing onto the car 5 can grasp it. Figure 1 The illustration of armrest 27 is omitted in the text. Figure 2 and Figure 3 At the position of the car 5, in the vertical direction, the handrail 27 is located between the upper and lower ends of the second device 23. When performing maintenance on the second device 23, for example, the car 5 is stopped at this position. In this position, the maintenance personnel climbing on the car 5 can easily reach the second device 23.

[0046] In the illustrated example, the upper vibration damper 25 and the lower vibration damper 26 have the same or similar structures. Therefore, in principle, the structures of the upper vibration damper 25 and the lower vibration damper 26 are described using common drawings in this invention. However, not limited to the illustrated example, in this invention, the shape or structure of the upper vibration damper 25 may differ from that of the lower vibration damper 26.

[0047] Figure 4 and Figure 6 These are perspective views of the upper vibration damping component 25 and the lower vibration damping component 26, respectively. Figure 5 This is an exploded perspective view of the upper vibration damping component 25 and the lower vibration damping component 26. Figure 9 Is with Figure 4 The corresponding three-view drawing. Figure 10 Is with Figure 6 The corresponding three-view drawing.

[0048] As shown in these figures, the upper vibration damper 25 and the lower vibration damper 26 each have a base 28 and a rotating portion 29 capable of changing its rotational position relative to the base 28. The base 28 is fixed in the shaft 7. Figure 3 In this example, the base 28 is mounted on the track 17. As a variation, the base 28 may also have a structure that allows it to be mounted on the wall of the shaft 7, or on the beams or columns of a building.

[0049] The rotating part 29 is in contact with the control cable 2. The rotating part 29 is capable of changing its rotational position relative to the base 28 between at least a first rotational position and a second rotational position different from the first rotational position. Figure 4 and Figure 9 This shows the state in which the rotating parts 29 of the upper vibration damper 25 and the lower vibration damper 26 are fixed in the first rotation position.

[0050] Under normal conditions without maintenance, the rotating portions 29 of the upper anti-vibration member 25 and the lower anti-vibration member 26 are fixed in the first rotation position. Under normal conditions, the rotating portions 29 of the upper anti-vibration member 25 and the lower anti-vibration member 26 are in contact with the control cable 2, thereby reducing the swaying of the control cable 2 that may occur when the car 5 is raised or lowered.

[0051] In the illustrated example, the rotating part 29 includes a first contact part 29a that contacts the control cable 2 from one side, and a second contact part 29b that contacts the control cable 2 from the other side. Located in Figure 4 and Figure 9 In the first rotational position, the first contact portion 29a contacts the control cable 2 from the same side as the second device 23. When located in the first rotational position... Figure 4 and Figure 9 In the first rotational position, the second contact portion 29b contacts the control cable 2 from the side opposite to the second device 23. In the illustrated example, by including the second contact portion 29b in addition to the first contact portion 29a, the position of the control cable 2 can be adjusted more appropriately. In the illustrated example, the second contact portion 29b is a component different from the first contact portion 29a, for example, it is installed on the first contact portion 29a by thread. Alternatively, in this invention, the second contact portion 29b may be omitted.

[0052] In the location Figure 4 and Figure 9 In the first rotational position, the contact surfaces of the first contact portion 29a and the second contact portion 29b are perpendicular to the horizontal plane.

[0053] Figure 6 and Figure 10 The diagram shows the upper vibration damper 25 with its rotating portion 29 fixed in a second rotational position. In the upper vibration damper 25, the second rotational position is the position after the rotating portion 29 has rotated 90 degrees from the first rotational position in the first direction. In the upper vibration damper 25, the second rotational position is the position where the contact surface of the first contact portion 29a faces upwards.

[0054] Although the illustration is omitted, in the lower vibration damping member 26, the second rotational position is the position after the rotating part 29 has rotated 90 degrees from the first rotational position to a second direction opposite to the first direction. In the lower vibration damping member 26, the second rotational position is the position where the contact surface of the first contact part 29a faces downward.

[0055] The upper vibration damper 25 and the lower vibration damper 26 each have a rotation axis 30. The rotating part 29 is capable of rotating relative to the base 28 about the rotation axis 30. The center line of the rotation axis 30 corresponds to the rotation center line of the rotating part 29 relative to the base 28. In the illustrated example, the rotation center line of the rotating part 29 relative to the base 28 is horizontal. That is, the length direction of the rotation axis 30 is arranged horizontally. Furthermore, the rotation center line of the rotating part 29 relative to the base 28 is parallel to the plane of the front of the housing, which is the second device 23. In this embodiment, since the rotation center line of the rotating part 29 relative to the base 28 is horizontal, no twisting of the control cable 2 around the axis occurs when the rotating part 29 is rotated. Therefore, the possibility of twisting of the control cable 2 can be reduced. Alternatively, in this invention, the rotation center line of the rotating part 29 relative to the base 28 can also be parallel to a vertical line.

[0056] like Figure 5 As shown, the rotating part 29 has a first end face 29c adjacent to the base 28. The first end face 29c is perpendicular to the contact surface of the first contact part 29a. A threaded hole 29d is provided at the center of the first end face 29c. An external thread is formed on at least the front end portion of the rotating shaft 30. The front end portion of the rotating shaft 30 is inserted into the threaded hole 29d. In the first end face 29c, a pair of protrusions 29e are provided on both sides of the threaded hole 29d.

[0057] Figure 7 This is a three-dimensional view of base 28. (For example...) Figure 7 As shown, the base 28 is a component with a "U"-shaped cross-section. The base 28 has a mounting surface 28a, a first support 28b, and a second support 28c. In the mounting surface 28a, holes are formed for bolts to pass through to fix the base 28 to the track 17, etc.

[0058] The first support portion 28b and the second support portion 28c are perpendicular to the mounting surface 28a. The first support portion 28b and the second support portion 28c are parallel to each other. The first support portion 28b is adjacent to the first end face 29c of the rotating portion 29.

[0059] In the first support portion 28b, a shaft hole 28d is formed for the rotating shaft 30 to pass through. In the second support portion 28c, a shaft hole 28e is formed for the rotating shaft 30 to pass through.

[0060] In the first support portion 28b, a pair of first positioning holes 28f and a pair of second positioning holes 28g are provided around the shaft hole 28d. The position of the pair of second positioning holes 28g is the position after rotating 90 degrees with respect to the position of the pair of first positioning holes 28f around the shaft hole 28d.

[0061] Figure 8 This is a three-dimensional view of the rotation axis 30. (Example) Figure 8 As shown, a rubber washer 31 is provided at the base end of the rotating shaft 30.

[0062] The front end portion of the rotating shaft 30 passes through the shaft hole 28e of the second support portion 28c of the base 28, then through the shaft hole 28d of the first support portion 28b, and further into the threaded hole 29d of the rotating portion 29. Then, when the rotating shaft 30 is rotated and tightened, the rotating portion 29 is fixed to the base 28. With the rotating shaft 30 tightened, the first end face 29c of the rotating portion 29 contacts the first support portion 28b of the base 28. When the rotating shaft 30 is released, the rotating portion 29 slides in a direction parallel to the rotating shaft 30, and the first end face 29c of the rotating portion 29 moves away from the first support portion 28b of the base 28.

[0063] When the rotating part 29 is fixed in the first rotational position, the protrusion 29e of the rotating part 29 is inserted into the first positioning hole 28f of the base 28. Therefore, the rotating part 29 cannot rotate from the first rotational position, thus reliably maintaining the rotating part 29 in the first rotational position. The protrusion 29e and the first positioning hole 28f correspond to a first positioning unit capable of positioning the rotating part 29 in the first rotational position. The first positioning unit is not limited to the example shown. For example, as the first positioning unit, a protrusion may be provided in the base 28, and a positioning hole or recess into the rotating part 29 may be provided for insertion of the protrusion.

[0064] When the rotating part 29 is fixed in the second rotational position, the protrusion 29e of the rotating part 29 is inserted into the second positioning hole 28g of the base 28. Therefore, the rotating part 29 cannot rotate from the second rotational position, thus more reliably maintaining the rotating part 29 in the second rotational position. The protrusion 29e and the second positioning hole 28g correspond to a second positioning unit capable of positioning the rotating part 29 in the second rotational position. The second positioning unit is not limited to the example shown. For example, as the second positioning unit, a protrusion may be provided in the base 28, and a positioning hole or recess into the rotating part 29 may be provided for insertion of the protrusion.

[0065] In the illustrated example, the rotating portion 29 has a shape with its length direction parallel to the rotation axis 30. The rotating portion 29 has a pair of side edges 29f. The pair of side edges 29f extend along the length direction of the rotating portion 29. The pair of side edges 29f are parallel to each other. A first contact portion 29a is provided between the pair of side edges 29f. The side edges 29f have a rib-like shape perpendicular to the contact surface of the first contact portion 29a. The side edges 29f are perpendicular to the first end face 29c.

[0066] In the illustrated example, holes for receiving portions 29g (not shown) serving as receiving rods are provided on each of the pair of side edges 29f. A rod that can act as an operating lever when rotating the rotating part 29 can be inserted into the receiving portion 29g. For example, a long screwdriver can be used as the rod. The rod inserted into the receiving portion 29g is perpendicular to the rotation center line of the rotating part 29.

[0067] When the rotating part 29 is rotated, the weight of the control cable 2, which hangs downward from the rotating part 29, acts on the rotating part 29. Therefore, when the hoistway 7 is long and the control cable 2 is long, a large torque is required to rotate the rotating part 29. In the example shown, the maintenance personnel can place their hand on a rod inserted into the receiving part 29g and use the rod as an operating lever to rotate the rotating part 29. Therefore, even when the control cable 2 is long, the rotating part 29 can be rotated with less effort.

[0068] In this embodiment, both the upper vibration damper 25 and the lower vibration damper 26 are equipped with detectors 32, which detect when the rotating part 29 is fixed in a first rotational position. The detector 32 is mounted at the position of the first positioning hole 28f in the base 28. The detector 32 can detect when the rotating part 29 is fixed in the first rotational position. When the rotating shaft 30 is tightened and the protrusion 29e is inserted into the first positioning hole 28f at the first rotational position, the contact of the detector 32 closes. When the rotating shaft 30 is loosened and the protrusion 29e is pulled out of the first positioning hole 28f, the contact of the detector 32 opens. Thus, the detector 32 can detect whether the rotating part 29 is fixed in the first rotational position. In this embodiment, by providing the detector 32, it is possible to automatically detect whether the rotating part 29 is fixed in the first rotational position.

[0069] exist Figure 2 In this configuration, the rotating portions 29 of the upper anti-vibration member 25 and the lower anti-vibration member 26 are each in a first rotating position. In this state, there is sufficient clearance between the control cable 2 between the upper and lower anti-vibration members 25 and the car 5 and the handrail 27. Therefore, even if the car 5 passes the position of the second device 23, neither the car 5 nor the handrail 27 can come into contact with the control cable 2.

[0070] like Figure 2 As shown, let D1 be the distance between the second device 23 and the control cable 2 when the rotating parts 29 of the upper vibration damper 25 and the lower vibration damper 26 are in the first rotating position. Distance D1 is the shortest distance between the surface of the housing of the second device 23 and the control cable 2.

[0071] Figure 11 It shows from Figure 2The side view shows the state in which the control cable 2 is pulled closer to the handrail 27 and the control cable 2 is temporarily fixed to the handrail 27. Figure 11 In the example, control cable 2 is bent into an "L" shape around the portion fixed to handrail 27. When maintaining the second device 23, assuming it becomes... Figure 11 This presents the following problems: The distance between the upper end of the second device 23 and the control cable 2 cannot be adequately ensured. The distance between the lower end of the second device 23 and the control cable 2 cannot be adequately ensured. This results in the need for labor-intensive and time-consuming work to pull the control cable 2 closer to the handrail 27 and temporarily secure it there. When adjusting the vertical position of the car 5 during maintenance, the control cable 2 must be temporarily detached from the handrail 27. Therefore, in... Figure 11 In the example, it is difficult to maintain the second device 23.

[0072] Figure 12 This is a side view showing the state of the rotating portions 29 of the upper vibration damper 25 and the lower vibration damper 26 when they are in the second rotational position. When from... Figure 2 When the state causes the rotating part 29 of the upper vibration damping member 25 to rotate 90 degrees counterclockwise in the first direction shown in the figure, and the rotating part 29 of the lower vibration damping member 26 to rotate 90 degrees clockwise in the second direction shown in the figure, it becomes Figure 12 The state.

[0073] like Figure 12 As shown, let D2 be the distance between the second device 23 and the control cable 2 when the rotating parts 29 of the upper vibration damper 25 and the lower vibration damper 26 are in the second rotating position. Distance D2 is the shortest distance between the surface of the housing of the second device 23 and the control cable 2. Figure 12 The distance D2 is greater than Figure 2 The distance D1 is longer.

[0074] By setting Figure 12 In this way, the position of the control cable 2 between the upper vibration damper 25 and the lower vibration damper 26 can be moved away from the second device 23. Therefore, maintenance of the second device 23 can be easily performed.

[0075] Figure 12 The distance between the upper end of the second device 23 and the control cable 2 is greater than that between the two devices. Figure 11 The distance between the upper end of the second device 23 and the control cable 2 is large. Figure 12 The distance between the lower end of the second device 23 and the control cable 2 is greater than... Figure 11 The distance between the lower end of the second device 23 and the control cable 2 is large. If it is... Figure 12In this example, the distance between the second device 23 and the control cable 2 can be sufficiently ensured from the top to the bottom of the second device 23. Therefore, by setting it to... Figure 12 In that way, with Figure 11 Compared to the previous example, maintenance of the second device 23 is much easier. Furthermore, in Figure 12 In this example, when the rotating portions 29 of the upper anti-vibration member 25 and the lower anti-vibration member 26 are in the second rotating position, the length direction of the control cable 2 located between the upper anti-vibration member 25 and the lower anti-vibration member 26 is parallel to the vertical line. Therefore, sufficient distance can be reliably ensured between the control cable 2 and the device 2 over the entire area from the upper end to the lower end of the second device 23.

[0076] exist Figure 12 In the example described above, control cable 2 is not fixed to handrail 27. In this embodiment, it is not necessary to fix control cable 2 to handrail 27 when maintaining the second device 23. Therefore, labor and work time can be reduced. Furthermore, when adjusting the vertical position of the car 5 during maintenance, Figure 12 In this state, the car 5 can also be moved manually.

[0077] In this embodiment, the control cable 2 is sandwiched between the first contact portion 29a and the second contact portion 29b of the rotating part 29. The portion of the control cable 2 sandwiched between the first contact portion 29a and the second contact portion 29b rotates together with the rotating part 29. Therefore, in Figure 12 In this example, the control cable 2 that contacts the rotating part 29 is approximately horizontal. As a result, the distance D2 between the second device 23 and the control cable 2 becomes larger, thus making it easier to maintain the second device 23.

[0078] Figure 13 This is a side view showing the state in which the rotating portions 29 of both the upper and lower vibration damping members 25 and 26 are in a second rotational position, in a structure where the second contact portion 29b is not present in either of their respective rotating portions 29. Figure 13 In the example, the control cable 2 is in contact with the side edges 29f of the rotating portions 29 of the upper and lower vibration damping members 25 and 26, respectively, and the first contact portion 29a of the rotating portions 29 of both the upper and lower vibration damping members 25 and 26 is not in contact. Figure 13 As shown, even if the rotating part 29 does not have the structure of the second contact part 29b, by fixing the rotating parts 29 of the upper anti-vibration member 25 and the lower anti-vibration member 26 to the second rotating position, the distance between the second device 23 and the control cable 2 can be sufficiently ensured from the top to the bottom of the second device 23. Therefore, maintenance of the second device 23 can be easily performed. Figure 13In the example, the control cable 2 is temporarily fixed to the handrail 27. Figure 13 In some cases, the control cable 2 may not be fixed to the handrail 27.

[0079] If the rotating part 29 does not have the structure of the second contact part 29b, then when the car 5 rises to its highest point, the control cable 2 can disconnect from the upper anti-vibration member 25 and the lower anti-vibration member 26. Therefore, the upper anti-vibration member 25 and the lower anti-vibration member 26 can also be arranged at a position lower than half of the lifting stroke of the car 5.

[0080] Figure 14 This is a diagram showing an example of elevator assembly 1. (As shown...) Figure 14 As shown, the traction machine 9, the detector 32 of the upper vibration damper 25, the detector 32 of the lower vibration damper 26, the changeover switch 33, and the control device 14 are electrically connected. The changeover switch 33 is operated by maintenance personnel. The changeover switch 33 is used to switch between automatic and manual operation. Automatic operation is the operating mode in which the control device 14 automatically controls the movement of the car 5. Automatic operation is the normal operating mode when no maintenance work is performed on the elevator device 1. Manual operation is the operating mode in which the car 5 is moved manually by maintenance personnel during maintenance work on the elevator device 1. During maintenance work, the maintenance personnel switch the changeover switch 33 from automatic to manual operation. When the maintenance work is completed, the maintenance personnel switch the changeover switch 33 from manual to automatic operation.

[0081] Figure 15 This is a flowchart illustrating an example of the operation of the control device 14. When the switch 33 is switched to manual operation, the control device 14 performs... Figure 15 The flowchart processing is as follows: In step S1, the control device 14 determines whether the switch 33 has been switched from manual operation to automatic operation. If the switch 33 has not been switched from manual operation to automatic operation, as in step S2, the control device 14 disables automatic operation and maintains the manual operation mode.

[0082] When the switch 33 is switched from manual to automatic operation in step S1, as step S3, the control device 14 determines whether the contacts of the detectors 32 on both the upper vibration damper 25 and the lower vibration damper 26 are closed. If the contacts of the detectors 32 on either the upper vibration damper 25 or the lower vibration damper 26 are open, as step S2, the control device 14 disables automatic operation and maintains the manual operation mode.

[0083] When the contacts of the detectors 32 of both the upper anti-vibration member 25 and the lower anti-vibration member 26 are closed in step S3, that is, when it is detected that the rotating parts 29 of both the upper anti-vibration member 25 and the lower anti-vibration member 26 are fixed in the first rotation position, the control device 14 allows automatic operation as step S4.

[0084] In the above example, even if the switch 33 has been switched to manual operation, the control device 14 prohibits the automatic operation of the car 5 if it does not detect that the rotating parts 29 of both the upper and lower anti-vibration members 25 and 26 are fixed in the first rotation position. That is, the control device 14 prohibits the automatic operation of the car 5 as long as the rotating part 29 of either the upper or lower anti-vibration member 25 is not fixed in the first rotation position, even if the switch 33 has been switched to manual operation. During automatic operation, the car 5 moves at a higher speed than during manual operation. If the car 5 moves at high speed through automatic operation as long as the rotating part 29 of either the upper or lower anti-vibration member 25 is not fixed in the first rotation position, there is a possibility that the car 5 will collide with the control cable 2. In this case, as in the example above, automatic operation is reliably prevented as long as the rotating part 29 of either the upper anti-vibration member 25 or the lower anti-vibration member 26 is not fixed in the first rotation position, thus more reliably preventing the high-speed moving car 5 from colliding with the control cable 2.

[0085] The following is an example of the work procedures for maintaining the second device 23.

[0086] (1) Maintenance personnel climb onto the car 5. The maintenance personnel stop the car 5 at a position where they can reach the upper vibration damping component 25.

[0087] (2) The maintenance personnel loosen the rotating shaft 30 of the upper anti-vibration component 25.

[0088] (3) The maintenance personnel slide the rotating part 29 of the upper vibration damping member 25 laterally and pull the protrusion 29e out of the first positioning hole 28f of the base 28.

[0089] (4) When the protrusion 29e is pulled out from the first positioning hole 28f, the contact of the detector 32 of the upper anti-vibration member 25 is disconnected. As a result, automatic operation is prohibited.

[0090] (5) The maintenance personnel insert the rod into the receiving part 29g of the rotating part 29 of the upper vibration damping member 25, and use the rod as an operating lever to rotate the rotating part 29 90 degrees from the first rotation position to the second rotation position in the first direction.

[0091] (6) With the protrusion 29e of the rotating part 29 of the upper vibration damper 25 aligned with the second positioning hole 28g of the base 28, the maintenance personnel tighten the rotating shaft 30. Thus, the rotating part 29 of the upper vibration damper 25 is fixed in the second rotation position.

[0092] (7) The maintenance personnel move the car 5 to a position where they can reach the lower anti-vibration component 26 by hand, and stop the car 5.

[0093] (8) The maintenance personnel loosen the rotating shaft 30 of the lower anti-vibration component 26.

[0094] (9) The maintenance personnel slide the rotating part 29 of the lower vibration damping member 26 laterally and pull the protrusion 29e out of the first positioning hole 28f of the base 28.

[0095] (10) When the protrusion 29e is pulled out from the first positioning hole 28f, the contact of the detector 32 of the lower vibration damper 26 is disconnected.

[0096] (11) The maintenance personnel insert the rod into the receiving part 29g of the rotating part 29 of the lower vibration damping member 26, and use the rod as an operating lever to rotate the rotating part 29 90 degrees from the first rotation position to the second rotation position.

[0097] (12) With the protrusion 29e of the rotating part 29 of the lower vibration damper 26 aligned with the second positioning hole 28g of the base 28, the maintenance personnel tighten the rotating shaft 30. Thus, the rotating part 29 of the lower vibration damper 26 is fixed in the second rotation position.

[0098] (13) Maintenance personnel perform maintenance on the second equipment 23.

[0099] (14) When the maintenance of the second equipment 23 is completed, the maintenance personnel move the car 5 to a position where the upper anti-vibration component 25 can be reached by hand, and stop the car 5.

[0100] (15) The maintenance personnel loosen the rotating shaft 30 of the upper anti-vibration component 25.

[0101] (16) The maintenance personnel slide the rotating part 29 of the upper vibration damping member 25 laterally and pull the protrusion 29e out of the second positioning hole 28g of the base 28.

[0102] (17) The maintenance personnel insert the rod into the receiving part 29g of the rotating part 29 of the upper vibration damping member 25 and use the rod as an operating lever to rotate the rotating part 29 90 degrees in such a way that it returns from the second rotating position to the second rotating position.

[0103] (18) With the protrusion 29e of the rotating part 29 of the upper vibration damper 25 aligned with the first positioning hole 28f of the base 28, the maintenance personnel tighten the rotating shaft 30. This fixes the rotating part 29 of the upper vibration damper 25 in a first rotational position. Furthermore, by inserting the protrusion 29e into the first positioning hole 28f, the contact of the detector 32 of the upper vibration damper 25 is closed.

[0104] (19) The maintenance personnel move the car 5 to a position where they can reach the lower anti-vibration component 26 by hand, and stop the car 5.

[0105] (20) The maintenance personnel loosen the rotating shaft 30 of the lower anti-vibration component 26.

[0106] (21) The maintenance personnel slide the rotating part 29 of the lower vibration damping member 26 laterally and pull the protrusion 29e out of the second positioning hole 28g of the base 28.

[0107] (22) The maintenance personnel insert the rod into the receiving part 29g of the rotating part 29 of the lower vibration damper 26 and use the rod as an operating lever to rotate the rotating part 29 90 degrees in such a way that it returns from the second rotating position to the second rotating position.

[0108] (23) With the protrusion 29e of the rotating part 29 of the lower vibration damper 26 aligned with the first positioning hole 28f of the base 28, the maintenance personnel tighten the rotating shaft 30. This fixes the rotating part 29 of the lower vibration damper 26 in a first rotational position. Furthermore, by inserting the protrusion 29e into the first positioning hole 28f, the contact of the detector 32 of the lower vibration damper 26 is closed.
