Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a traction component restraint device and a lifting system. Background Technology

[0002] Wind power generation devices, such as wind turbines, are turbines that use wind energy as power, and their power generation cost is only half that of conventional turbines. Because wind turbines require regular maintenance and are over 100 meters high, a lifting system is installed inside the wind turbine tower to transport workers, tools, or materials from the starting point to the designated work platform.

[0003] In a lifting system, the elevator is raised by traction components (such as steel wire ropes). The elevator is also equipped with safety steel wire ropes and power cables. When the elevator moves up and down along the shaft of the tower, the steel wire ropes extending along the elevator's path may swing or become entangled. For example, the steel wire ropes may become entangled with each other or with the power cable. This not only affects the normal operation of the elevator but also makes it difficult to restore the entangled cables.

[0004] Therefore, in related technologies, a wire rope anti-sway device is added to the lifting system to limit the swing of the wire rope and improve the stability of the elevator operation. To improve the installation efficiency of the wire rope anti-sway device, an installation position is reserved for the device after the tower is manufactured. However, due to manufacturing and installation errors, the reserved installation position deviates significantly from the design position, making the installation of the anti-sway device difficult.

[0019] The constraint rod or the adjusting rod is provided with a positioning part near its end, and the positioning member is adapted to pass through the positioning part to position the constraint body.

[0020] According to the traction restraint device provided by this utility model, the support member includes a first support part, a second support part, and a connecting part. The first support part and the second support part are disposed at opposite ends of the connecting part. The first support part, the second support part, and the connecting part enclose to form a limiting groove. The restraint rod or the adjusting rod is adapted to be limited to the limiting groove.

[0021] According to the traction member constraint device provided by this utility model, the top of the first support part is provided with a first extension part, and the top of the second support part is provided with a second extension part.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0053] Figure 1 This is a schematic diagram of the traction restraint device provided in Embodiment 1 of this utility model. Figure 2 This is a top view of the traction restraint device provided in Embodiment 1 of this utility model.

[0054] See Figure 1 and Figure 2 This utility model provides a traction component restraint device 100, which is used to restrain the traction component (such as a steel wire rope) of a lifting system to limit the swinging of the steel wire rope of the lifting machine 300 and improve the stability of the lifting machine 300 operation. The traction component restraint device 100 includes a restraint body 10 and a mounting component 20.

[0055] The constraint body 10 includes a constraint rod 11 and an adjusting rod 12. The constraint rod 11 can be a rod or a prism, and the shape of the adjusting rod 12 is adapted to the shape of the constraint rod 11. The constraint rod 11 has a first end and a second end that are disposed opposite to each other, and the adjusting rod 12 is disposed at least one of the first end and the second end. The adjusting rod 12 is telescopic relative to the constraint rod 11. With this configuration, by adjusting the telescopic length of the adjusting rod 12 relative to the constraint rod 11, the overall length of the constraint body 10 can be changed, thereby enabling the traction constraint device 100 to be installed under different positional deviations.

[0056] Mounting components 20 are located on opposite sides of the constraint body 10. Mounting components 20 include a bracket 21 and a support 22. The bracket 21 is adapted to be installed at a preset mounting position 200 on the tower. The support 22 is located on the bracket 21 and is adapted to support the constraint rod 11 or the adjusting rod 12. When the adjusting rods 12 are symmetrically arranged at both ends of the constraint rod 11, the adjusting rods 12 overlap the support 22. When the adjusting rod 12 is located at one end of the constraint rod 11, the adjusting rod 12 overlaps the support 22 on one side, and the constraint rod 11 overlaps the support 22 on the other side.

[0057] The preset installation position 200 of the tower includes, but is not limited to, the toe plate 210 of the tower platform 220, the bottom surface of the tower platform 220, and the support or bracket 230 erected on the inner wall of the tower. For example, an installation hole is made on the tower platform 220 to install the traction restraint device 100 from below onto the tower platform 220; or an installation hole is made on the toe plate 210 to install the traction restraint device 100 on the toe plate 210. Alternatively, an installation hole is made on the support or bracket 230 erected on the tower wall to install the traction restraint device 100 on the support or bracket 230. The specific installation position of the traction restraint device 100 is not limited to the positions exemplified above; any position that allows the traction restraint device 100 to be fixed to the preset installation position 200 within the tower shaft is acceptable.

[0058] For example, when the traction restraint device 100 is installed on the shaft wall of the tower platform 220, the width of the shaft does not match the installation dimensions of the traction restraint device 100, that is, the width of the shaft is greater than the length of the restraint body 10, or the width of the shaft is less than the length of the restraint body 10. By adjusting the extension length of the adjusting rod 12 relative to the restraint rod 11, the overall length of the restraint body 10 can be changed, so that the traction restraint device 100 can be installed under different positional deviations.

[0059] It is understood that the traction restraint device 100 provided in this embodiment of the present invention includes a restraint body 10 and an installation component 20. The installation component 20 is located on opposite sides of the restraint body 10. The installation component 20 includes a bracket 21 and a support member 22. The bracket 21 is adapted to be installed onto the tower, and the support member 22 is disposed on the bracket 21 and adapted to support the restraint body 10. The restraint body 10 includes a restraint rod 11 and an adjusting rod 12. The restraint rod 11 has a first end and a second end disposed opposite to each other. The adjusting rod 12 is disposed on at least one of the first end and the second end, and the adjusting rod 12 is telescopic relative to the restraint rod 11.

[0060] This configuration allows for adjustment of the telescopic length of the adjusting rod 12 relative to the constraint rod 11, thereby changing the overall length of the constraint body 10 and adapting to installation positions of different widths. When the width of the shaft inside the tower does not match the installation dimensions of the traction restraint device 100—that is, the width of the shaft is greater than the length of the constraint body 10, or the width of the shaft is less than the length of the constraint body 10—the overall length of the constraint body 10 can be changed by adjusting the telescopic length of the adjusting rod 12 relative to the constraint rod 11. This ensures that the traction restraint device 100 can be installed under different positional deviations, making it applicable under various deviations.

[0061] Continue reading Figure 2 In some embodiments of this utility model, one of the constraint rod 11 and the adjustment rod 12 is provided with an adjustment hole 111, and the other of the constraint rod 11 and the adjustment rod 12 is provided with an adjustment member 121 that cooperates with the adjustment hole 111 for positioning; multiple adjustment holes 111 are provided at intervals along the axial direction of the constraint rod 11 or the adjustment rod 12, and the adjustment member 121 cooperates with different adjustment holes 111 for positioning.

[0062] For example, near both ends of the constraint rod 11, multiple adjustment holes 111 are spaced apart along the length of the constraint rod 11. An adjustment element 121 is provided on the adjustment rod 12. By moving the position of the adjustment rod 12 relative to the constraint rod 11, the adjustment element 121 and different adjustment holes 111 are matched and positioned to adjust the overall length of the constraint body 10. This allows the traction constraint device 100 to be installed under different positional deviations, that is, it is applicable under different deviations.

[0063] The adjusting component 121 can be a pin or bolt independent of the adjusting rod 12, or a spring positioning pin, etc., set on the adjusting rod 12.

[0064] When the adjusting member 121 is a pin, a positioning hole can be provided on the adjusting rod 12. By moving the position of the adjusting rod 12 relative to the constraint rod 11, the positioning hole is aligned with one of the adjusting holes 111. The pin is then inserted into the adjusting hole 111 and the positioning hole in sequence for positioning, so as to limit the relative position of the adjusting rod 12 and the constraint rod 11.

[0065] When the adjusting member 121 is a spring positioning pin, a positioning hole can be provided on the adjusting rod 12, the spring positioning pin is set at the position of the positioning hole and extends out of the positioning hole, the spring positioning pin is squeezed to retract into the positioning hole, and then the position of the adjusting rod 12 relative to the constraint rod 11 is moved until the positioning hole is aligned with one of the adjusting holes 111, the spring positioning pin automatically inserts into the adjusting hole 111 for positioning, so as to limit the relative position of the adjusting rod 12 and the constraint rod 11.

[0066] In addition, an adjusting member 121 can be provided on the constraint rod 11, and multiple adjusting holes 111 can be provided at intervals along the length direction of the adjusting rod 12. By moving the position of the adjusting rod 12 relative to the constraint rod 11, the adjusting member 121 and different adjusting holes 111 can be matched and positioned to adjust the overall length of the constraint body 10. This allows the traction member constraint device 100 to be installed under different positional deviations, that is, it can be used under different deviations.

[0067] In addition, the constraint body 10 can also be set as a multi-stage telescopic rod, with a locking structure used between adjacent telescopic rods for limiting. Any structure that can adjust the overall length of the constraint body 10 is acceptable.

[0068] Figure 3 This is one of the schematic diagrams showing the usage state of the traction restraint device provided in Embodiment 1 of this utility model. Figure 4 This is the second schematic diagram of the usage state of the traction restraint device provided in Embodiment 1 of this utility model.

[0069] See Figure 3 and Figure 4 This utility model embodiment takes the installation of the traction restraint device 100 on the toe plate 210 of the tower platform 220 as an example. Mounting holes are opened on two opposite sides of the toe plate 210 of the tower platform 220. The bracket 21 of the mounting component 20 is fixed to the toe plate 210 by the first fastener 30. The two ends of the restraint body 10 are attached to the support member 22 of the mounting component 20.

[0070] When the elevator 300 moves upward, the restraint body 10 falls into the limit slot 311 of the elevator 300, such as Figure 3 As shown, the elevator 300 continues to move upward, and the constraint body 10 moves upward synchronously with the elevator 300, as... Figure 4 As shown. When the elevator 300 moves downward and passes the position of the mounting component 20, both ends of the restraint body 10 fall into the support members 22 on both sides respectively. The elevator 300 continues to move downward, and the restraint body 10 stops on the support members 22 of the mounting component 20.

[0071] Additionally, it should be noted that a rope guide 70 can be provided on the restraint body 10. The rope guide 70 has rope guide holes (not labeled in the figure). The steel wire ropes of the elevator 300, such as the traction steel wire rope and the safety steel wire rope, pass through different rope guide holes, providing guidance for the traction steel wire rope and the safety steel wire rope, preventing the steel wire ropes from swinging or tangling together, and preventing tangling between the steel wire ropes and the power supply cable. In some embodiments, without the rope guide 70, rope guide holes are provided within the restraint body 10 itself to provide guidance for the traction steel wire rope and the safety steel wire rope, preventing the steel wire ropes from swinging or tangling together, and preventing tangling between the steel wire ropes and the power supply cable.

[0072] Continue reading Figure 1 and Figure 2 In some embodiments of this utility model, the bracket 21 is provided with at least one first adjustment part 211, that is, one, two or three first adjustment parts 211 may be provided. The length direction of the first adjustment part 211 is perpendicular to the axial direction of the constraint body 10; the first fastener 30 for connecting the bracket 21 and the preset installation position 200 (i.e. the toe plate 210 of the tower platform 220) passes through the first adjustment part 211.

[0073] When the reserved installation position for the traction restraint device 100 deviates in the direction perpendicular to the restraint body 10, and the restraint body 10 cannot fall into the support 22, or is not positioned in the center of the support 22 after falling into the support 22, the position of the first adjustment part 211 relative to the installation hole opened on the preset installation position 200 (toe plate 210 of the tower platform 220) is adjusted, and then fixed by the first fastener 30, thereby adjusting the position of the bracket 21 and the support 22 in the vertical direction, so that the restraint body 10 can fall smoothly into the support 22 and be positioned in the center of the support 22 after falling into the support 22, thereby improving the reliability of the traction restraint device 100 falling into the support 22.

[0074] Figure 5 This is one of the top views of the traction restraint device in use provided in Embodiment 1 of this utility model. Figure 6 This is one of the front views of the traction restraint device in use provided in Embodiment 1 of this utility model. Figure 7 This is a second top view of the traction restraint device provided in Embodiment 1 of this utility model in its usage state. Figure 8 This is the second front view of the traction restraint device in use provided in Embodiment 1 of this utility model.

[0075] like Figure 5 and Figure 6As shown, when the reserved installation position for the traction restraint device 100 deviates in the direction of the vertical restraint body 10, the restraint body 10 cannot fall into the support 22, or after falling into the support 22, it is not positioned at the center of the support 22.

[0076] like Figure 7 and Figure 8 As shown, at this time, the position of the first adjustment part 211 relative to the mounting hole opened on the preset installation position 200 (such as the toe plate 210 of the tower platform 220) can be adjusted, and then fixed by the first fastener 30, thereby adjusting the position of the bracket 21 and the support 22 in the vertical direction, so that the restraint body 10 can fall smoothly into the support 22, and after falling into the support 22, it is positioned at the center of the support 22, so as to improve the reliability of the traction restraint device 100 falling into the support 22.

[0077] The first adjustment part 211 can be an oblong hole, a keyway, or a plurality of through holes spaced apart. The configuration of the first adjustment part 211 is selected according to actual use.

[0078] It is understood that the traction restraint device 100 provided in this embodiment of the present invention can not only change the overall length of the restraint body 10 by adjusting the extension length of the adjusting rod 12 relative to the restraint rod 11, thereby enabling the traction restraint device 100 to be installed under different positional deviations, this adjustment is equivalent to adjusting the installation size of the traction restraint device 100 in the horizontal direction, but also adjust the position of the mounting hole opened on the first adjusting part 211 relative to the preset installation position 200 (such as the toe plate 210 of the tower platform 220) and then fix it with the first fastener 30, thereby adjusting the position of the bracket 21 and the support member 22 in the vertical direction, this adjustment is equivalent to adjusting the installation size of the traction restraint device 100 in the vertical direction.

[0079] This embodiment adjusts the traction restraint device 100 from the above two aspects, which can improve the reliability of the traction restraint device 100 falling into the support 22 and further adapt to installation under different deviations. This solves the problem in related technologies where, due to manufacturing and installation errors, the reserved installation position deviates significantly from the design position, leading to difficulties in installing the anti-sway device.

[0080] Continue reading Figure 6 and Figure 8 In some embodiments of this utility model, the traction member constraint device 100 further includes a positioning member 60, which is disposed on the support member 22 and can be a pin.

[0081] A positioning part 122 is provided near the end of either the constraint rod 11 or the adjusting rod 12. Specifically, when the adjusting rod 12 is symmetrically arranged at both ends of the constraint rod 11, a positioning part 122 is provided near the end of each adjusting rod 12; when the adjusting rod 12 is arranged at one end of the constraint rod 11, a positioning part 122 is provided near the end of both the constraint rod 11 and the adjusting rod 12. The positioning part 122 is suitable for positioning the constraint body 10 by passing through the positioning member 60, thereby improving the stability of the constraint body 10.

[0082] The positioning part 122 can be a waist hole or a keyway, which can provide a passage allowance for the positioning member 60, so that the positioning member 60 can be inserted into the positioning part 122 for positioning.

[0083] Figure 9 This is one of the structural schematic diagrams of the traction restraint device provided in Embodiment 2 of this utility model. Figure 10 This is the second structural schematic diagram of the traction restraint device provided in Embodiment 2 of this utility model. Figure 11 This is one of the schematic diagrams showing the usage state of the traction restraint device provided in Embodiment 2 of this utility model. Figure 12 This is the second schematic diagram of the usage state of the traction restraint device provided in Embodiment 2 of this utility model.

[0084] See Figure 9 and Figure 12 In some embodiments of this utility model, the bracket 21 includes a first frame 212 and a second frame 213 connected to each other. The first frame 212 is adapted to be installed at a preset installation position 200, and the support member 22 is disposed on the second frame 213.

[0085] Essentially, the structure of the bracket 21 can be adaptively adjusted according to its installation position. For example, when the bracket 21 is installed on the toe plate 210 of the tower platform 220 via the first fastener 30, the bracket 21 is a single unit. When the bracket 21 is installed on the bottom surface of the tower platform 220 or on the support 230 of the inner wall of the tower, the bracket 21 consists of a first frame 212 and a second frame 213 that are separately configured.

[0086] It should be noted that regardless of how the structure of bracket 21 is adjusted according to its installation position, the constraint process of the traction restraint device 100 remains unchanged. For example:

[0087] When the elevator 300 moves upward, the restraint body 10 falls into the limit slot 311 of the elevator 300, such as Figure 11 As shown, the elevator 300 continues to move upward, and the constraint body 10 moves upward synchronously with the elevator 300, as... Figure 12As shown. When the elevator 300 moves downward and passes the position of the mounting component 20, both ends of the restraint body 10 fall into the support members 22 on both sides respectively. The elevator 300 continues to move downward, and the restraint body 10 stops on the support members 22 of the mounting component 20.

[0088] Continue reading Figure 9 In some embodiments of this utility model, the second frame 213 is provided with at least one second adjustment part 214 along its own length direction, that is, one, two or three second adjustment parts 214 can be provided, and the extension direction of the second adjustment part 214 is perpendicular to the axial direction of the constraint body 10; the second fastener 40 for connecting the first frame 212 and the second frame 213 passes through the second adjustment part 214.

[0089] In other words, in this embodiment of the present invention, the second frame 213 of the bracket 21 is indirectly assembled with the preset installation position 200 through the first frame 212, which can further adapt to installation under different deviations.

[0090] Since the first frame 212 and the second frame 213 are manufactured using the same process, while the second frame 213 and the preset installation position 200 are manufactured using different processes, the second frame 213 is indirectly assembled with the preset installation position 200 through the first frame 212, which is easier than the second bracket 21 being directly assembled with the preset installation position 200. Therefore, by opening a second adjustment part 214 on the second frame 213 and adjusting its position relative to the mounting hole on the first frame 212, the position of the constraint body 10 relative to the preset installation position 200 (such as the toe plate 210 of the tower platform 220) can be indirectly adjusted, which can further improve the reliability of the traction restraint device 100 falling into the support member 22.

[0091] The second adjustment part 214 has the same structure as the first adjustment part 211. The second adjustment part 214 can be an oblong hole, a keyway, or a plurality of through holes spaced apart. The configuration of the first adjustment part 211 is selected according to actual use.

[0092] Figure 13 This is a bottom view of the traction restraint device provided in Embodiment 3 of this utility model. Figure 14 This is a top view of the traction restraint device provided in Embodiment 3 of this utility model.

[0093] See Figure 13 and Figure 14 Based on the above embodiment 2, unlike the above embodiment 2, the bracket 21 is provided with a plurality of third adjustment parts 215, and the centers of the plurality of third adjustment parts 215 are located at the same pitch circle; the third fastener 50 for connecting the bracket 21 and the support member 22 passes through one of the third adjustment parts 215.

[0094] When the bracket 21 is installed on the toe plate 210 of the tower platform 220 by the first fastener 30, the bracket 21 is an integral part. The angle change of the traction restraint device 100 is achieved by connecting the support member 22 with different third adjustment parts 215.

[0095] When the bracket 21 is installed on the bottom surface of the tower platform 220 or on the support 230 of the inner wall of the tower, the bracket 21 is composed of a first frame 212 and a second frame 213 that are set separately. Multiple third adjustment parts 215 can be provided on the second frame 213, and the centers of the multiple third adjustment parts 215 are located at the same pitch circle. A third fastener 50 for connecting the second frame 213 and the support member 22 passes through one of the third adjustment parts 215.

[0096] In other words, by setting multiple third adjustment parts 215 on the same pitch circle, the angle of the constraint body 10 relative to the preset installation position 200 can be adjusted, thereby ensuring that the support member 22 of the installation component 20 is aligned with the constraint body 10, so that the constraint body 10 can fall smoothly into the support member 22.

[0097] For example, when the traction restraint device 100 is installed in the platform opening of the tower platform 220, if the position of the platform opening is skewed, the angle of the restraint body 10 relative to the preset installation position 200 can be adjusted by adjusting the installation position of the third fastener 50 and the third adjustment part 215, thereby ensuring that the support 22 of the installation component 20 is aligned with the restraint body 10, so that the restraint body 10 can fall smoothly into the support 22.

[0098] It is understood that the traction restraint device 100 provided in this embodiment of the present invention can not only change the overall length of the restraint body 10 by adjusting the extension length of the adjusting rod 12 relative to the restraint rod 11, so that the traction restraint device can be installed under different positional deviations, but this adjustment is equivalent to adjusting the installation size of the traction restraint device 100 in the horizontal direction.

[0099] Furthermore, when the bracket 21 is installed as a single unit, by adjusting the position of the first adjustment part 211 relative to the mounting hole opened on the preset installation position 200 (such as the toe plate 210 of the tower platform 220), and then fixing it with the first fastener 30, this adjustment is equivalent to adjusting the installation dimensions of the traction member constraint device 100 in the vertical direction. This improves the reliability of the traction member constraint device 100 falling into the support member 22 and further adapts to installation under different deviations.

[0100] When the bracket 21 is composed of the first frame 212 and the second frame 213, the position of the constraint body 10 relative to the preset installation position 200 (such as the toe plate 210 of the tower platform 220) can be indirectly adjusted by opening a second adjustment part 214 on the second frame 213 and adjusting it relative to the position of the mounting hole on the first frame 212. This can further improve the reliability of the traction constraint device 100 falling into the support 22 and adapt to installation under different deviations.

[0101] In addition, when the traction restraint device 100 is installed in the platform opening of the tower platform 220, if the position of the platform opening is skewed, the angle of the restraint body 10 relative to the preset installation position 200 can be adjusted by adjusting the installation position of the third fastener 50 and the third adjustment part 215, thereby ensuring that the support member 22 of the installation component 20 is aligned with the restraint body 10, so as to ensure that the restraint body 10 falls smoothly into the support member 22.

[0102] In other words, the traction restraint device 100 provided in this embodiment of the present invention allows the adjusting restraint body 10 to be adjusted in three aspects: horizontal, vertical and angular, relative to the preset installation position 200, so as to optimize the stability of the traction restraint device 100, adapt to the installation of the traction restraint device 100 under various deviation working conditions, and improve the safety of the elevator 300 during operation.

[0103] Continue reading Figure 6 and Figure 8 In some embodiments of this utility model, the support member 22 includes a first support portion 221, a second support portion 222, and a connecting portion 223. The first support portion 221 and the second support portion 222 are disposed at opposite ends of the connecting portion 223 to form a structure similar to a "U". The first support portion 221, the second support portion 222, and the connecting portion 223 enclose a "U"-shaped limiting groove, and the constraint rod 11 or the adjusting rod 12 is adapted to be limited to the limiting groove.

[0104] Continue reading Figure 6 and Figure 8 In some embodiments of this utility model, the top of the first support portion 221 is provided with a first extension portion 224, and the top of the second support portion 222 is provided with a second extension portion 225. Thus, when the first support portion 221 and the second support portion 222 are provided at opposite ends of the connecting portion 223, a structure similar to a "Y" shape is formed.

[0105] As the gap between the first extension 224 and the second extension 225 gradually narrows from the opening position away from the limiting groove towards the opening of the limiting groove, it facilitates the smooth entry of the restraint body 10 into the limiting groove.

[0106] In addition, extensions may be provided in the horizontal direction at the ends of the first extension 224 and the second extension 225.

[0107] Figure 15 This is a schematic diagram of the traction restraint device provided in Embodiment 4 of this utility model.

[0108] This utility model embodiment also provides a lifting system that can be applied to wind turbines and other wind power generation devices. The lifting system includes a lift 300 and any of the traction restraint devices 100.

[0109] The traction restraint device 100 is configured according to the height of the wind turbine tower. When the tower height is within a preset range, one traction restraint device 100 can be installed near the middle of the tower to limit the swinging or entanglement of the wire rope of the elevator 300. When the tower height is high, two traction restraint devices 100 are installed near the middle of the tower.

[0110] The top of the elevator 300 is provided with a limiting member 310, and the limiting member 310 is provided with a limiting slot 311; when the elevator 300 moves to the position of the traction member restraint device 100, the restraint body 10 of the traction member restraint device 100 is engaged in the limiting slot 311.

[0111] See Figure 15 When the tower is relatively high, two traction restraint devices 100 are installed near the middle of the tower. Correspondingly, two sets of limiting members 310 are provided opposite to each other on the top of the elevator 300, namely the first limiting member and the second limiting member, and each set of limiting members 310 is provided with a limiting slot 311.

[0112] When the elevator 300 moves upward to the position of the first traction restraint device 100, the restraint body 10 of the first traction restraint device 100 falls into the limiting slot 311 of the first limiting member 310 of the elevator 300; the elevator 300 continues to move upward, and the restraint body 10 of the first traction restraint device 100 moves upward synchronously with the elevator 300. When the elevator 300 moves upward to the position of the second traction restraint device 100, the restraint body 10 of the second traction restraint device 100 falls into the limiting slot 311 of the second limiting member 310 of the elevator 300, as... Figure 15 As shown; the elevator 300 continues to move upward, and the constraint body 10 of the second traction constraint device 100 moves upward synchronously with the elevator 300.

[0113] When the elevator 300 moves downward and passes the location of the mounting component 20 of the second traction restraint device 100, both ends of the restraint body 10 of the second traction restraint device 100 fall into the support members 22 on both sides. The elevator 300 continues to move downward, and the restraint body 10 of the second traction restraint device 100 rests on the support members 22 of the mounting component 20. When the elevator 300 continues to move downward and passes the location of the mounting component 20 of the first traction restraint device 100, both ends of the restraint body 10 of the first traction restraint device 100 fall into the support members 22 on both sides. The elevator 300 continues to move downward, and the restraint body 10 of the first traction restraint device 100 rests on the support members 22 of the mounting component 20.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
