[0022] The embodiments will now be described with reference to the accompanying drawings.

[0023] Implementation Method 1

[0024] Figure 1 This is a schematic structural diagram showing the main parts of the elevator in Embodiment 1. The elevator in Embodiment 1 is a machine-room-less elevator.

[0025] The hoistway 1 is equipped with a car 2 serving as an elevator, a counterweight (not shown), and a traction machine (not shown).

[0026] The traction machine has a drive sheave. A suspension body (not shown) is wound around the drive sheave. Multiple ropes or belts are used as the suspension body. The car 2 and counterweight are suspended by the suspension body. Furthermore, the car 2 and counterweight move up and down within the hoistway 1 by rotating the drive sheave.

[0027] The hoistway 1 is equipped with a first car guide rail 3, a second car guide rail (not shown), a first counterweight guide rail (not shown), and a second counterweight guide rail (not shown). The first car guide rail 3 and the second car guide rail guide the lifting and lowering of the car 2. The first counterweight guide rail and the second counterweight guide rail guide the lifting and lowering of the counterweight.

[0028] A control panel 4 is installed at the top of the hoistway 1. The control panel 4 is supported on the first car guide rail 3 via an equipment support device 5. The control panel 4 controls the operation of the car 2 by controlling the traction machine.

[0029] A control cable 6 connects the control panel 4 and the car 2. Figure 1 In this design, the connection point of the control cable 6 to the car 2 is omitted. The control cable 6 is electrically connected to the control panel 4. Furthermore, the control cable 6 supplies power to the car 2 and transmits signals between the control panel 4 and the car 2. Additionally, the control cable 6 is flexible.

[0030] Figure 2 It is shown in magnification Figure 1 The main view of the main parts. The first car guide rail 3 is constructed by joining multiple rail components 7 in the vertical direction. The adjacent rail components 7 are connected by a joint plate 8.

[0031] The first car guide rail 3 is fixed to multiple rail brackets 9. The multiple rail brackets 9 are fixed in the hoistway 1 at intervals in the vertical direction.

[0032] The equipment support device 5 is mounted on the first car guide rail 3. In addition, the equipment support device 5 has an upper mounting arm 11, a lower mounting arm 12, an adapter 13, and a cable clamp 14.

[0033] The upper mounting arm 11 is mounted on the first car guide rail 3 using multiple first rail clamps 15. That is, the upper mounting arm 11 is mounted on the first car guide rail 3 by clamping the first car guide rail 3 between each first rail clamp 15 and the upper mounting arm 11.

[0034] The upper end of the control panel 4 is fixed to the upper mounting arm 11 using multiple upper panel mounting parts 16. Each upper panel mounting part 16 is, for example, a combination of bolts and nuts.

[0035] The lower mounting arm 12 is mounted on the first car guide rail 3 below the upper mounting arm 11. Furthermore, the lower mounting arm 12 is mounted on the first car guide rail 3 using multiple second rail clamps 17. That is, the lower mounting arm 12 is mounted on the first car guide rail 3 by clamping the first car guide rail 3 between each of the second rail clamps 17 and the lower mounting arm 12.

[0036] The adapter 13 is constructed of a rectangular flat plate. Furthermore, the adapter 13 is mounted to the lower mounting arm 12 using multiple arm mounts 18. That is, the adapter 13 is supported on the first car guide rail 3 via the lower mounting arm 12. Each arm mount 18 is, for example, a combination of bolts and nuts.

[0037] The lower end of the control panel 4 is secured to the adapter 13 using multiple lower panel mounting pieces 19. Each lower panel mounting piece 19 is, for example, a combination of bolts and nuts.

[0038] Cable clamp 14 is mounted on adapter 13. Furthermore, cable clamp 14 clamps and secures a portion of control cable 6. Thus, control cable 6 is suspended from adapter 13. Additionally, cable clamp 14 is positioned vertically spaced relative to the lower end of control panel 4.

[0039] Figure 3 It is shown in magnification Figure 2 The main view of Part III. Figure 4 It is shown Figure 3 Side view of cable clamp 14.

[0040] The vertical dimension of the lower mounting arm 12 is smaller than that of the adapter 13. The adapter 13 has multiple arm mounting holes 13a. The number of arm mounting holes 13a is greater than the number of arm mounting members 18. Each arm mounting member 18 is inserted into one arm mounting hole 13a selected from the multiple arm mounting holes 13a.

[0041] By selecting the arm mounting hole 13a from among the multiple arm mounting holes 13a into which each arm mounting member 18 is to be inserted, the mounting position of the lower mounting arm 12 relative to the adapter 13 can be adjusted. That is, the mounting position of the lower mounting arm 12 relative to the adapter 13 can be adjusted in the vertical direction.

[0042] The cable clamp 14 has a first pressing member 21 and a second pressing member 22. The control cable 6 is clamped between the first pressing member 21 and the second pressing member 22.

[0043] A first protrusion 21a is provided at the middle of the first pressing member 21 in the vertical direction, protruding away from the adapter 13. A second protrusion 22a is provided at the middle of the second pressing member 22 in the vertical direction, protruding in the same direction as the first protrusion 21a. The control cable 6 is bent between the first protrusion 21a and the second protrusion 22a in a manner that protrudes away from the adapter 13.

[0044] The first pressing member 21 is mounted to the adapter 13 using multiple first clip mounting members 23. Each first clip mounting member 23 is, for example, a bolt. The second pressing member 22 is mounted to the adapter 13 using multiple second clip mounting members 24. Each second clip mounting member 24 is, for example, a bolt.

[0045] The adapter 13 is provided with a plurality of first clamp mounting holes 13b and a plurality of second clamp mounting holes 13c. The plurality of first clamp mounting holes 13b and the plurality of second clamp mounting holes 13c are threaded holes.

[0046] Insert and screw the corresponding first clamp mounting piece 23 into each of the first clamp mounting holes 13b. Insert and screw the corresponding second clamp mounting piece 24 into each of the second clamp mounting holes 13c.

[0047] In this elevator and its equipment support device 5, a control panel 4 and a cable clamp 14 are installed in a common adapter 13. Moreover, the adapter 13 is mounted to the first car guide rail 3 via the lower mounting arm 12.

[0048] Therefore, the lower part of the control panel 4 and the control cable 6 can be mounted to the first car guide rail 3 via a shared lower mounting arm 12, reducing the number of parts. Furthermore, it reduces the labor and time required for mounting the lower part of the control panel 4 and the control cable 6 to the first car guide rail 3.

[0049] Furthermore, the mounting position of the lower mounting arm 12 relative to the adapter 13 can be adjusted in the vertical direction. Therefore, interference between the lower mounting arm 12 and the track bracket 9 or the joint plate 8 can be easily avoided.

[0050] Furthermore, the cable clamps 14 are arranged at intervals in the vertical direction relative to the lower end of the control panel 4. Therefore, the operability of connecting the control cable 6 to the control panel 4 can be improved.

[0051] Implementation Method 2

[0052] then, Figure 5 This is a front view showing the equipment support device 5 of the elevator according to Embodiment 2. Figure 6 It is shown in magnification Figure 5 The front view of section VI. In embodiment 2, the lower mounting arm 12 and the adapter 13 are configured as a single component. That is, the lower mounting arm 12 and the adapter 13 are configured by bending a single flat plate.

[0053] The vertical dimension of the lower mounting arm 12 is the same as the vertical dimension of the adapter 13. Except... Figure 6 The elevator structure, except for the structure of the equipment support device 5 shown, is the same as that in Embodiment 1.

[0054] In this elevator and its equipment support device 5, the number of parts can be further reduced compared to the structure of embodiment 1.

[0055] In addition, in Embodiment 2, similar to Embodiment 1, the vertical dimension of the lower mounting arm 12 can be made smaller than the vertical dimension of the adapter 13.

[0056] Implementation Method 3

[0057] then, Figure 7This is a front view showing the main parts of the equipment support device 5 of the elevator according to Embodiment 3. The equipment support device 5 of Embodiment 3 has an additional mounting arm 25 on the basis of the same structure as that of Embodiment 1.

[0058] The additional mounting arm 25 is mounted on the first car guide rail 3 below the lower mounting arm 12. Furthermore, the additional mounting arm 25 is mounted on the first car guide rail 3 using multiple third rail clips 26. That is, the additional mounting arm 25 is mounted on the first car guide rail 3 by clamping the first car guide rail 3 between each third rail clip 26 and the additional mounting arm 25.

[0059] In embodiment 3, the lower mounting arm 12 extends to the side opposite to the first car guide rail 3 compared to the adapter 13. The additional mounting arm 25 has the same dimensions as the lower mounting arm 12 in the width direction of the first car guide rail 3. The width direction of the first car guide rail 3 is parallel to the front-rear direction of the car 2. Figure 7 The left and right directions.

[0060] An optional disk 27 is provided between the lower mounting arm 12 and the additional mounting arm 25. The optional disk 27 may be, for example, a transformer or an additional battery.

[0061] The optional tray 27 is supported by the lower mounting arm 12 and the additional mounting arm 25. That is, the optional tray 27 is supported on the first car guide rail 3 via the equipment support device 5.

[0062] In addition, the optional disk 27 can be mounted to the lower mounting arm 12 and the additional mounting arm 25 using multiple additional mounting parts 28. Each additional mounting part 28 may be a combination of bolts and nuts, for example.

[0063] Apart from Figure 7 The elevator structure, except for the structure of the equipment support device 5 shown, is the same as that in Embodiment 1.

[0064] With this structure, the lower part of the control panel 4 and the control cable 6 can also be mounted on the first car guide rail 3 via a shared lower mounting arm 12, which can reduce the number of parts.

[0065] In addition, in Embodiment 3, similar to Embodiment 2, the lower mounting arm 12 and the adapter 13 can also be configured as a single component.

[0066] Implementation Method 4

[0067] then, Figure 8This is a front view showing the equipment support device 5 of the elevator according to Embodiment 4. The vertical dimension of the adapter 13 in Embodiment 4 is larger than the vertical dimension of the control panel 4. Furthermore, the width dimension of the adapter 13 is larger than the width dimension of the control panel 4. The width directions of the adapter 13 and the control panel 4 are parallel to the width direction of the first car guide rail 3. Figure 8 The left and right directions.

[0068] The upper end of the adapter 13 is mounted to the upper mounting arm 11 using multiple arm mounting members 18. The lower end of the adapter 13 is mounted to the lower mounting arm 12 using multiple arm mounting members 18. That is, the adapter 13 is supported on the first car guide rail 3 via the upper mounting arm 11 and the lower mounting arm 12.

[0069] The upper part of the control panel 4 is fixed to the adapter 13 using multiple upper panel mounting pieces 16. In addition... Figure 8 The elevator structure, except for the structure of the equipment support device 5 shown, is the same as that in Embodiment 1.

[0070] With this structure, the lower part of the control panel 4 and the control cable 6 can also be mounted on the first car guide rail 3 via a shared lower mounting arm 12, which can reduce the number of parts.

[0071] Furthermore, in embodiment 4, the control panel 4 can also be divided into multiple parts in the vertical or width direction. That is, the control panel 4 can also be composed of multiple partitioned panels.

[0072] Furthermore, in embodiment 4, at least one of the upper mounting arm 11 and the lower mounting arm 12 and the adapter 13 can also be configured as a single component.

[0073] Furthermore, in Embodiment 4, similar to Embodiment 3, an additional mounting arm 25 and an optional disk 27 may be added.

[0074] Furthermore, in embodiments 1 to 4, the lifting body can also be a counterweight. That is, the guide rail can also be a counterweight guide rail.

[0075] Furthermore, in embodiments 1 to 4, the overall layout of the elevator is not limited to... Figure 1 The layout can be varied. For example, the control panel 4 can also be configured outside the top of the shaft 1.

[0076] In addition, elevators can also be elevators with machine rooms, double-decker elevators, or single-shaft multi-car elevators. A single-shaft multi-car elevator is one in which the upper car and the lower car, located directly below the upper car, move independently within a shared shaft.
