Detailed Implementation

[0023] Implementation Method 1

[0024] The moving device of the elevator traction machine according to Embodiment 1, the elevator traction machine, the elevator traction machine with the moving device, and the moving method of the elevator traction machine will be described. Figure 1 This is a cross-sectional view showing the moving device of the elevator traction machine and the structure of the elevator traction machine according to this embodiment. Figure 1 The diagram shows a cross-section obtained by cutting the moving device 11 of the elevator traction machine and the elevator traction machine 10 in a plane containing the axis 30c of the rotating shaft component 30. Figure 1 The left and right directions indicate the direction along the axis 30c of the rotating shaft component 30, that is, the axial direction of the rotating shaft component 30.

[0025] Figure 2 This is a side view showing the moving device of the elevator traction machine and the structure of the elevator traction machine according to this embodiment. Figure 2 The diagram shows the structure of the elevator traction machine 10 and the moving device 11 of the elevator traction machine, viewed along the axis 30c. Figure 1 and Figure 2 The vertical direction indicates the vertical direction.

[0026] In the following description, the moving device of the elevator traction machine is sometimes referred to simply as the "moving device". Furthermore, in the following description, the moving device 11 and the elevator traction machine 10 are sometimes referred to together as an "elevator traction machine with a moving device". That is, an elevator traction machine with a moving device includes both the moving device 11 and the elevator traction machine 10.

[0027] When moving the elevator traction machine 10, such as Figure 1 and Figure 2 The moving device 11 is installed on the elevator traction machine 10 as shown. After the elevator traction machine 10 is moved, the moving device 11 is removed from the elevator traction machine 10.

[0028] like Figure 1 and Figure 2 As shown, the elevator traction machine 10 has a housing 20, a rotating shaft assembly 30, and a pulley 31. The housing 20 has a housing body 21 and a bearing housing 22. The bearing housing 22 is disposed opposite to the housing body 21 across the pulley 31.

[0029] The rotating shaft component 30 has an end portion 30a on one axial end and an end portion 30b on the other axial end. End portion 30a of the rotating shaft component 30 is rotatably supported on the housing body 21 by means of a bearing 23. End portion 30b of the rotating shaft component 30 is rotatably supported on a bearing seat 22 by means of a bearing 24. Thus, the rotating shaft component 30 is rotatable relative to the housing 20 about its axis 30c. The rotating shaft component 30 is supported on the housing 20 with its axis 30c horizontal.

[0030] The pulley 31 is fixed to the rotating shaft component 30. The pulley 31 is fixed to the axial center of the rotating shaft component 30, which is located between end 30a and end 30b. The pulley 31 rotates integrally with the rotating shaft component 30. That is, the pulley 31 can rotate freely relative to the housing 20 about the axis 30c.

[0031] After the elevator traction machine 10 is installed in the machine room, multiple ropes are wound around the rope sheave 31. One end of each rope is connected to the elevator car. The other end of each rope is connected to the counterweight.

[0032] An outer peripheral surface 31a is formed at one axial end of the pulley 31. The housing body 21 is formed to surround the outer peripheral surface 31a of the pulley 31. An inner peripheral surface 21a is formed on the housing body 21. The inner peripheral surface 21a of the housing body 21 is opposite to the outer peripheral surface 31a of the pulley 31.

[0033] A stator (not shown) is provided on the inner circumferential surface 21a of the housing body 21. A rotor (not shown) is provided on the outer circumferential surface 31a of the pulley 31. The stator and rotor are positioned opposite each other with a gap between them. The rotor rotates by energizing the stator. The rotation of the rotor causes the pulley 31 and the rotating shaft assembly 30 to rotate.

[0034] The moving device 11 has a first wheel 40, a second wheel 50, a first mounting component 42, and a second mounting component 52. The first wheel 40 is detachably mounted to the elevator traction machine 10 by means of the first mounting component 42. The second wheel 50 is detachably mounted to the elevator traction machine 10 by means of the second mounting component 52. The radius R1 of the first wheel 40 and the radius R2 of the second wheel 50 are equal to each other.

[0035] The first wheel 40 and the second wheel 50 are arranged side by side. The first wheel 40 is axially disposed at one end of the elevator traction machine 10. The second wheel 50 is axially disposed at the other end of the elevator traction machine 10.

[0036] The first wheel 40 and the second wheel 50 are fixed to the rotating shaft component 30. Thus, the first wheel 40 and the second wheel 50 rotate integrally with the rotating shaft component 30. That is, the first wheel 40 and the second wheel 50 can rotate freely relative to the housing 20 about the axis 30c.

[0037] When observing the first wheel 40 and the second wheel 50 along the axis 30c, let the outline representing the outer periphery of the first wheel 40 be OL1, and the outline representing the outer periphery of the second wheel 50 be OL2. Both outlines OL1 and OL2 are circles centered on the axis 30c. When observing the first wheel 40 and the second wheel 50 along the axis 30c, outlines OL1 and OL2 coincide with each other.

[0038] When observing the elevator traction machine 10 along axis 30c, let the outline representing the overall contour of the elevator traction machine 10 be OL3. Figure 2 In the diagram, the outline OL3 is represented by a thick dashed line. When viewing the elevator traction machine 10, the first wheel 40, and the second wheel 50 along the axis 30c, the outline OL3 is contained inside the outline OL1 and inside the outline OL2. That is, when viewed along the axis 30c, the longest distance L1 between the outline OL3 of the elevator traction machine 10 and the axis 30c is shorter than either the radius R1 of the first wheel 40 or the radius R2 of the second wheel 50 (L1 < R1 = R2).

[0039] The first wheel 40 has a wheel body 41, a tire 43, and an inner tube 44. The wheel body 41 has a circular outer periphery. A rim 41a is formed on the outer periphery of the wheel body 41.

[0040] The inner tube 44 has an overall annular shape. The inner tube 44 is positioned along the outer periphery of the wheel body 41. The inner tube 44 has an elliptical or circular cross-sectional shape. The inner tube 44 is formed of a stretchable material such as rubber or resin. Air is filled inside the inner tube 44. The air-filled inner tube 44 functions as a cushioning component, mitigating the impact transmitted to the elevator traction machine 10 via the first wheel 40. In this embodiment, the air-filled inner tube 44 is used as a cushioning component, but it is not limited to this. Cushioning components made of various materials such as foamed materials and water-soluble substances can be used.

[0041] The tire 43 is formed by covering the inner tube 44. When the elevator traction machine 10 moves, the tire 43 protects the inner tube 44 from impacts and vibrations from the ground surface such as the floor and stairs. The tire 43 is mounted on the rim 41a.

[0042] The first mounting component 42 is disposed at the center of the first wheel 40. The first mounting component 42 is detachably mounted to the end 30a of the rotating shaft component 30. Thus, the first wheel 40 is detachably mounted to the rotating shaft component 30 of the elevator traction machine 10 by means of the first mounting component 42.

[0043] A first mating portion 32a is formed at the end 30a of the rotating shaft component 30, and this first mating portion 32a engages with the first mounting component 42. Both the first mounting component 42 and the first mating portion 32a have concave-convex structures. When the first mounting component 42 and the first mating portion 32a are engaged, the concave-convex structures of the first mounting component 42 and the first mating portion 32a mesh with each other. Thus, torque is transmitted between the first mounting component 42 and the rotating shaft component 30. Therefore, the first wheel 40 and the first mounting component 42 rotate integrally with the rotating shaft component 30.

[0044] The second wheel 50 has the same structure as the first wheel 40. The second wheel 50 has a wheel body 51, a tire 53, and an inner tube 54. The wheel body 51 has a circular outer periphery. A rim 51a is formed on the outer periphery of the wheel body 51. The inner tube 54 is positioned along the outer periphery of the wheel body 51. The tire 53 is formed to cover the inner tube 54. The tire 53 is mounted on the rim 51a.

[0045] The second mounting component 52 is disposed at the center of the second wheel 50. The second mounting component 52 is detachably mounted to the end 30b of the rotating shaft component 30. Thus, the second wheel 50 is detachably mounted to the rotating shaft component 30 of the elevator traction machine 10 by means of the second mounting component 52.

[0046] A second mating portion 32b is formed at the end 30b of the rotating shaft component 30, and this second mating portion 32b engages with the second mounting component 52. Both the second mounting component 52 and the second mating portion 32b have concave-convex structures. When the second mounting component 52 and the second mating portion 32b are engaged, the concave-convex structures of the second mounting component 52 and the second mating portion 32b mesh with each other. Thus, torque is transmitted between the second mounting component 52 and the rotating shaft component 30. Therefore, the second wheel 50 and the second mounting component 52 rotate integrally with the rotating shaft component 30.

[0047] When moving the elevator traction machine 10, the first wheel 40 and the second wheel 50 of the moving device 11 are mounted on the elevator traction machine 10. In this state, when a force perpendicular to the axis 30c and along the road surface is applied to the elevator traction machine 10, the first wheel 40 and the second wheel 50 rotate together with the rotating shaft component 30 and the sheave 31. The elevator traction machine 10 travels on the road surface by the rotation of the first wheel 40 and the second wheel 50. Thus, the elevator traction machine 10 can be moved by rotating the first wheel 40 and the second wheel 50.

[0048] As described above, the moving device 11 of the elevator traction machine in this embodiment includes a first wheel 40 and a second wheel 50. The first wheel 40 is detachably mounted to the elevator traction machine 10 by means of a first mounting member 42, the elevator traction machine 10 having a rotating shaft member 30 and a sheave 31. The second wheel 50 is detachably mounted to the elevator traction machine 10 alongside the first wheel 40 by means of a second mounting member 52. The first wheel 40 and the second wheel 50 are rotatable about the axis 30c of the rotating shaft member 30. When viewing the elevator traction machine 10, the first wheel 40, and the second wheel 50 along the axis 30c, the outline OL3 representing the outline of the elevator traction machine 10 is contained inside the outline OL1 representing the outer peripheral outline of the first wheel 40, and inside the outline OL2 representing the outer peripheral outline of the second wheel 50.

[0049] According to this structure, the centers of the first wheel 40 and the second wheel 50 are aligned with the axis 30c of the rotating shaft component 30. Therefore, it is possible to prevent the center of gravity of the elevator traction machine 10, on which the first wheel 40 and the second wheel 50 are mounted, from rising, and to increase the diameter of each of the first wheel 40 and the second wheel 50. Therefore, when the elevator traction machine 10 is moved using the moving device 11, it is possible to prevent the moving device 11 from tipping over due to unstable surfaces. Furthermore, since the diameters of the first wheel 40 and the second wheel 50 can be increased, it becomes easier to raise and lower the moving device 11 on stairs. Therefore, according to this structure, the elevator traction machine 10 can move stably.

[0050] Furthermore, when viewed along the axis 30c, the outline OL3 of the elevator traction machine 10 is contained inside the outline OL1 of the first wheel 40 and the outline OL2 of the second wheel 50. Therefore, when the elevator traction machine 10 is moved using the moving device 11, it is possible to prevent the elevator traction machine 10 from contacting the ground.

[0051] In the elevator traction machine moving device 11 of this embodiment, the first mounting member 42 is configured to mount the first wheel 40 to the rotating shaft member 30, and the second mounting member 52 is configured to mount the second wheel 50 to the rotating shaft member 30. With this structure, the first wheel 40 and the second wheel 50 can rotate integrally with the rotating shaft member 30, thus eliminating the need for additional bearings and enabling stable rotation of the first wheel 40 and the second wheel 50.

[0052] Furthermore, both the first wheel 40 and the second wheel 50 are freely rotatable relative to the housing 20 of the elevator traction machine 10. Therefore, the elevator traction machine 10 can be moved without rotating the housing 20. Thus, it is possible to prevent the movable wiring extending from the housing 20 from getting tangled in the first wheel 40, the second wheel 50, or other equipment.

[0053] In this embodiment, the elevator traction machine 10 is equipped with a moving device 11. The elevator traction machine 10 has a first mating part 32a and a second mating part 32b. The first mating part 32a is provided on the rotating shaft member 30. The first mating part 32a engages with the first mounting member 42. The second mating part 32b is provided on the rotating shaft member 30. The second mating part 32b engages with the second mounting member 52. With this structure, the elevator traction machine 10 can be moved stably using the moving device 11.

[0054] The elevator traction machine with a moving device in this embodiment includes a moving device 11 and an elevator traction machine 10. With this structure, the moving device 11 can be used to move the elevator traction machine 10 stably.

[0055] In the elevator traction machine moving method of this embodiment, the first wheel 40 and the second wheel 50 of the elevator traction machine moving device 11 of this embodiment are mounted on the elevator traction machine 10, and the first wheel 40 and the second wheel 50 are rotated to move the elevator traction machine 10. According to this moving method, the elevator traction machine 10 can be moved stably using the moving device 11.

[0056] Implementation Method 2

[0057] The moving device of the elevator traction machine and the elevator traction machine of Embodiment 2 will be described. Figure 3This is a cross-sectional view showing the moving device of the elevator traction machine and the structure of the elevator traction machine according to this embodiment. Furthermore, components having the same functions and effects as in Embodiment 1 are labeled with the same reference numerals and their descriptions are omitted.

[0058] like Figure 3 As shown, the first wheel 40 and the second wheel 50 are detachably mounted on the elevator traction machine 10. In this embodiment, the first wheel 40 and the second wheel 50 are fixed to the rope sheave 31.

[0059] The first wheel 40 is axially disposed on one end of the rope pulley 31. The first wheel 40 is mounted on the rope pulley 31 by means of a first mounting member 42. The first wheel 40 has an overall annular shape. The first mounting member 42 is disposed on the inner circumferential end of the first wheel 40.

[0060] A first mating portion 32a is formed on the pulley 31, which engages with the first mounting member 42. Both the first mounting member 42 and the first mating portion 32a have concave-convex structures. When the first mounting member 42 and the first mating portion 32a are engaged, the concave-convex structures of the first mounting member 42 and the first mating portion 32a mesh with each other. Thus, torque is transmitted between the first mounting member 42 and the pulley 31. Therefore, the first mounting member 42 and the first wheel 40 rotate integrally with the pulley 31.

[0061] The second wheel 50 is axially disposed on the other end of the rope pulley 31. The second wheel 50 is mounted on the rope pulley 31 by means of a second mounting member 52. The second wheel 50 has an overall annular shape. The second mounting member 52 is disposed on the inner circumferential end of the second wheel 50.

[0062] A second mating portion 32b is formed on the pulley 31, which engages with the second mounting member 52. Both the second mounting member 52 and the second mating portion 32b have concave-convex structures. When the second mounting member 52 and the second mating portion 32b are engaged, the concave-convex structures of the second mounting member 52 and the second mating portion 32b mesh with each other. Thus, torque is transmitted between the second mounting member 52 and the pulley 31. Therefore, the second mounting member 52 and the second wheel 50 rotate integrally with the pulley 31.

[0063] Although the illustration is omitted, when viewed along the axis 30c, the outline OL3 of the elevator traction machine 10 is contained inside the outline OL1 of the first wheel 40 and inside the outline OL2 of the second wheel 50.

[0064] As explained above, in the elevator traction machine moving device 11 of this embodiment, the first mounting member 42 is configured to mount the first wheel 40 to the sheave 31. The second mounting member 52 is configured to mount the second wheel 50 to the sheave 31. With this structure, the first wheel 40 and the second wheel 50 can rotate integrally with the sheave 31, thus eliminating the need for additional bearings and enabling stable rotation of the first wheel 40 and the second wheel 50.

[0065] Furthermore, both the first wheel 40 and the second wheel 50 are freely rotatable relative to the housing 20 of the elevator traction machine 10. Therefore, the elevator traction machine 10 can be moved without rotating the housing 20. Thus, it is possible to prevent the movable wiring extending from the housing 20 from getting tangled in the first wheel 40, the second wheel 50, or other equipment.

[0066] In this embodiment, the elevator traction machine 10 is equipped with a moving device 11. The elevator traction machine 10 of this embodiment has a first mating part 32a and a second mating part 32b. The first mating part 32a is provided on the sheave 31. The first mating part 32a engages with the first mounting member 42. The second mating part 32b is provided on the sheave 31. The second mating part 32b engages with the second mounting member 52. With this structure, the elevator traction machine 10 can be moved stably using the moving device 11.

[0067] Implementation Method 3

[0068] The moving device, elevator traction machine, and moving method of the elevator traction machine according to Embodiment 3 will be described. Figure 4 This is a cross-sectional view showing the moving device of the elevator traction machine and the structure of the elevator traction machine according to this embodiment. Furthermore, for components having the same function and effect as in Embodiment 1 or Embodiment 2, the same reference numerals are used, and their descriptions are omitted.

[0069] like Figure 4 As shown, the moving device 11 of the elevator traction machine in this embodiment differs from the moving device 11 of the elevator traction machine in Embodiment 1 in the construction of the first mounting member 42. The first mounting member 42 has an inner ring 42a, an outer ring 42b, and a rolling element 42c.

[0070] The inner ring 42a is detachably mounted on the end 30a of the rotating shaft component 30. The central axis of the inner ring 42a coincides with the axis 30c of the rotating shaft component 30. The inner ring 42a is fixed to the rotating shaft component 30. The inner ring 42a rotates integrally with the rotating shaft component 30 and the pulley 31 around the axis 30c.

[0071] The outer ring 42b is positioned on the outer periphery side of the inner ring 42a. The outer ring 42b is coaxial with the inner ring 42a. That is, the central axis of the outer ring 42b coincides with the axis 30c of the rotating shaft component 30. The outer ring 42b can rotate freely relative to the inner ring 42a about the axis 30c.

[0072] A rolling element 42c is disposed between the inner ring 42a and the outer ring 42b. The rolling element 42c is configured to roll between the inner ring 42a and the outer ring 42b.

[0073] The first wheel 40 is fixed to the outer rim 42b. Therefore, the first wheel 40 can rotate freely relative to the rotating shaft component 30 about the axle center 30c. That is, the first wheel 40 rotates independently of the rotating shaft component 30. On the other hand, the second wheel 50 rotates integrally with the rotating shaft component 30 about the axle center 30c. Therefore, the first wheel 40 and the second wheel 50 rotate independently of each other.

[0074] Alternatively, the inner ring 42a, outer ring 42b, and rolling element 42c can also be formed as a single component, acting as a rolling bearing. That is, the first wheel 40 can also be mounted on the rotating shaft component 30 by means of a rolling bearing. Even in this case, the first wheel 40 rotates independently of the rotating shaft component 30.

[0075] In this embodiment, since the first wheel 40 and the second wheel 50 rotate independently of each other, the elevator traction machine 10 can be easily turned. Therefore, even in narrow spaces such as stair landings, the direction of the elevator traction machine 10 can be easily changed.

[0076] The method for moving the elevator traction machine according to this embodiment will be described. Figure 5 This is a top view illustrating an example of the method for moving the elevator traction machine according to this embodiment. Figure 6 This is a side view illustrating an example of the method for moving the elevator traction machine according to this embodiment.

[0077] like Figure 5 and Figure 6 As shown, the computer room 102 is located at a higher position than the lower floor 100. A staircase 101 is provided between the lower floor 100 and the computer room 102. The computer room 102 is equipped with a beam 103, a chain hoist 104, and a fixed pulley 105. The chain hoist 104 is installed on the beam 103. The fixed pulley 105 is located at the same height as the beam 103.

[0078] When moving the elevator traction machine 10, the first wheel 40 and the second wheel 50 are installed on the elevator traction machine 10. The radius of each of the first wheel 40 and the second wheel 50 is larger than the height of one step of the staircase 101. A hinge bolt part 25 is installed on the housing body 21 of the elevator traction machine 10. The hinge bolt part 25 is also used for the installation work of the elevator traction machine 10. The hinge bolt part 25 is connected to the hook 104a of the chain hoist 104 by means of a line 106 that is wound around the fixed pulley 105.

[0079] When the chain hoist 104 pulls the elevator traction machine 10, the first wheel 40 and the second wheel 50 rotate, and the elevator traction machine 10 moves. The elevator traction machine 10 moves on the ground floor 100 and the stairs 101 of the lower floor 100 and is pulled to the machine room 102. Because the diameters of the first wheel 40 and the second wheel 50 are large, the elevator traction machine 10 can move stably on the ground floor 100 and the stairs 101 of the lower floor 100. Thus, the elevator traction machine 10 can be stably moved from the lower floor 100 to the machine room 102.

[0080] In this embodiment, the first mounting member 42 is configured to mount the first wheel 40 to the rotating shaft member 30, but the first mounting member 42 may also be configured to mount the first wheel 40 to the rope wheel 31.

[0081] In this embodiment, the first mounting member 42 has an inner ring, an outer ring, and rolling elements, but the second mounting member 52 may also have an inner ring, an outer ring, and rolling elements. In this case, the first wheel 40 rotates integrally with the rotating shaft member 30 and the pulley 31, while the second wheel 50 rotates independently with respect to the rotating shaft member 30 and the pulley 31. Thus, the first wheel 40 and the second wheel 50 rotate independently of each other. In this case, the second mounting member 52 may be configured to mount the second wheel 50 to the rotating shaft member 30, or it may be configured to mount the second wheel 50 to the pulley 31.

[0082] Alternatively, both the first mounting component 42 and the second mounting component 52 may have an inner ring, an outer ring, and rolling elements. In this case, the first wheel 40 and the second wheel 50 rotate independently of each other, and also independently of the rotating shaft component 30 and the sheave 31. Thus, the elevator traction machine 10 can be moved without rotating the housing 20, the rotating shaft component 30, and the sheave 31.

[0083] As explained above, in the moving device 11 of the elevator traction machine in this embodiment, at least one of the first mounting member 42 and the second mounting member 52 has an inner ring, an outer ring, and a rolling element. The inner ring is fixed to the rotating shaft member 30 or the pulley 31. The outer ring is located at a position closer to the outer periphery than the inner ring. The rolling element is disposed between the inner ring and the outer ring. With this structure, the first wheel 40 and the second wheel 50 can rotate independently of each other, thus making it easy to turn the elevator traction machine 10.

[0084] Furthermore, in this embodiment, both the first wheel 40 and the second wheel 50 are rotatable relative to the housing 20 of the elevator traction machine 10. Therefore, the elevator traction machine 10 can be moved without rotating the housing 20. Thus, it is possible to prevent the movable wiring extending from the housing 20 from getting tangled in the first wheel 40, the second wheel 50, or other equipment.

[0085] Implementation Method 4

[0086] The moving device of the elevator traction machine and the elevator traction machine of Embodiment 4 will be described. Figure 7 This is a cross-sectional view showing the moving device of the elevator traction machine and the structure of the elevator traction machine according to this embodiment. Furthermore, for components having the same function and effect as in any of embodiments 1 to 3, the same reference numerals are used, and their descriptions are omitted.

[0087] like Figure 7 As shown, a pair of bearings 26 and 27 are provided between the pulley 31 and the rotating shaft component 30. The pulley 31 is rotatably supported on the rotating shaft component 30 by means of the bearings 26 and 27. Thus, the pulley 31 rotates relative to the rotating shaft component 30 about the axis 30c. The rotating shaft component 30 is fixed to the housing 20.

[0088] The first wheel 40 is detachably mounted to the rotating shaft component 30 via a first mounting member 42. The first mounting member 42 has an inner ring 42a, an outer ring 42b, rolling elements 42c, and an auxiliary shaft component 42d. The auxiliary shaft component 42d is coaxially mounted to the end 30a of the rotating shaft component 30 on the anti-load side, serving as an aid for moving the elevator traction machine 10. The auxiliary shaft component 42d is detachably mounted to the rotating shaft component 30 using fixing members 45 such as screws. The inner ring 42a is fixed to the auxiliary shaft component 42d. The first wheel 40 is fixed to the outer ring 42b. Thus, the first wheel 40 can rotate freely relative to the auxiliary shaft component 42d and the rotating shaft component 30, with the axle 30c as its center.

[0089] The second wheel 50 is detachably mounted to the rope pulley 31 by means of the second mounting component 52. The second mounting component 52 is mounted to the rope pulley 31 using fasteners 55 such as screws. The second wheel 50 rotates freely relative to the rotating shaft component 30 with the axle 30c as the center. The second wheel 50 and the rope pulley 31 rotate independently of the first wheel 40.

[0090] In this embodiment, the first wheel 40 and the second wheel 50 can rotate independently of each other, thus making it easy to turn the elevator traction machine 10.

[0091] Furthermore, in this embodiment, since the second wheel 50 is mounted on the pulley 31, the second wheel 50 is rotatably supported on the rotating shaft component 30 by means of bearings 26 and 27. Therefore, the second mounting component 52 for mounting the second wheel 50 does not require an inner ring, an outer ring, and rolling elements.

[0092] Furthermore, in this embodiment, both the first wheel 40 and the second wheel 50 are rotatable relative to the housing 20 of the elevator traction machine 10. Therefore, the elevator traction machine 10 can be moved without rotating the housing 20. Thus, it is possible to prevent the movable wiring extending from the housing 20 from getting tangled in the first wheel 40, the second wheel 50, or other equipment.

[0093] The above embodiments can be combined with each other. For example, Embodiment 1 and Embodiment 2 can be combined, with one of the first wheel 40 and the second wheel 50 mounted on the rotating shaft component 30, and the other of the first wheel 40 and the second wheel 50 mounted on the rope pulley 31.
