[0016] One end of the snap-fit ​​component is inserted into the mounting space, and the first rotating shaft passes through the first mounting plate, the snap-fit ​​component, and the second mounting plate in sequence.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Embodiments of the invention will now be described in detail with reference to the accompanying drawings. Preferred embodiments of the invention will now be described in detail, examples of which are illustrated in the drawings. Wherever possible, the same reference numerals will be used in all the drawings to denote the same or similar parts. Furthermore, although the terminology used herein is selected from commonly known and used terminology, some terms mentioned in this specification may have been chosen by the applicant at his or her discretion, and their detailed meanings are explained in the relevant sections of the description herein. Moreover, the invention should be understood not only by the actual terms used, but also by the meaning implied by each term.

[0040] Please refer to Figure 1 and Figure 2 This invention proposes a fixing mechanism for a multi-wire rope pulley, including a mounting support 10, a first transition member 20, a connecting member 30, and a second transition member 40. One end of the mounting support 10 is connected to the main body of the swing device, and the other end is provided with a first rotating shaft 110. One end of the first transition member 20 is rotatably engaged with the first rotating shaft 110. One end of the connecting member 30 is detachably connected to the other end of the first transition member 20. The other end of the connecting member 30 is detachably connected to one end of the second transition member 40, and the other end of the second transition member 40 is provided with a second rotating shaft 410. Multiple wire ropes 50 are sleeved on the second rotating shaft 410 and arranged along the axial direction of the second rotating shaft 410. The axial direction of the first rotating shaft 110 and the axial direction of the second rotating shaft 410 are set at an angle.

[0041] One end of the mounting support 10 is connected to the main body of the swing device by welding or a threaded connection 30. The threaded connection 30 includes, but is not limited to, bolts or screws. The mounting support 10 is provided with a first rotating shaft 110, and the first transition piece 20 is rotatably engaged with the first rotating shaft 110. In this way, the first rotating shaft 110 can absorb the load along its axial direction and avoid the load along its axial direction from affecting the installation stability of the mounting support 10.

[0042] The second transition piece 40 is movably installed with the wire rope 50, and multiple wire ropes 50 are arranged side by side and rotate in cooperation with the second transition piece 40. The rotational cooperation of the wire ropes 50 along the second rotating shaft 410 can prevent the axial rotational load along the second rotating shaft 410 from being transmitted to the mounting support 10, thereby allowing the mounting support 10 to be free from the axial load of the second rotating shaft 410.

[0043] With the first rotating shaft 110 and the second rotating shaft 410 set at an angle, the mounting support 10 can absorb loads in different directions, reduce the excessive impact of the load generated by the rotation and pulling of the wire rope 50 on the mounting support 10, and improve the installation stability of the mounting support 10.

[0044] Furthermore, this application includes a connector 30, which is detachably connected to the first transition piece 20 and the second transition piece 40. This allows for disassembly via the connector 30 when a portion of the structure is damaged, reducing maintenance costs. For example, if the second transition piece 40 is damaged, the wire rope 50 can be removed, and then the connector 30 can be detached from the second transition piece 40. A new or repaired second transition piece 40 can then be reinstalled without disassembling the entire component, significantly reducing disassembly and reassembly costs and improving the efficiency of disassembly and reassembly of damaged components.

[0045] Similarly, when the first transition piece 20 or the mounting bracket 10 needs to be replaced, the connector 30 and the first transition piece 20 can be disassembled, and then the damaged parts can be replaced.

[0046] In one embodiment, the axial direction of the first rotating shaft 110 is perpendicular to the axial direction of the second rotating shaft 410. When the wire rope 50 is pulled and shakes, in order to avoid the load generated by the shaking acting directly on the mounting support 10, the load along the direction of the second rotating shaft 410 is first absorbed by the second transition member 40, and then the load of the first rotating shaft 110 is absorbed by the first transition member 20. This greatly reduces the load transmitted to the mounting support 10 and ensures the installation strength between the mounting support 10 and the swing device body.

[0047] When the load is transmitted, it is limited by the first rotating shaft 110 and the second rotating shaft 410. Most of the load will be turned to the axial direction of the first rotating shaft 110 and the second rotating shaft 410, and then converted into rotation between the mounting support 10 and the first transition member 20 and rotation between the second transition member 40 and the wire rope 50. This avoids the mounting support 10 from being subjected to a large stress impact due to a load in a single direction.

[0048] In one embodiment, the first transition member 20 includes a snap-fit ​​member 210 and a mounting member 220. One end of the snap-fit ​​member 210 is rotatably engaged with the first rotating shaft 110, and the mounting member 220 is rotatably engaged with the connector 30. The end of the mounting member 220 facing away from the connector 30 is detachably connected to the connector 30.

[0049] The snap-fit ​​part 210 and the mounting part 220 are connected by a rotating rod. The two ends of the rotating rod extend to the outside of the mounting part 220 and are limited by a locking nut. The axial direction of the rotating rod is consistent with the axial direction of the first rotating shaft 110.

[0050] For the mounting support 10, the mounting support 10 includes a top plate 120 and a first mounting plate 130 and a second mounting plate 140 spaced apart. One end of the first mounting plate 130 and the second mounting plate 140 is connected to the top plate 120, and one end of the top plate 120 is connected to the body of the swing device. An installation space 150 is formed between the first mounting plate 130 and the second mounting plate 140. One end of the snap-fit ​​member 210 is inserted into the installation space 150, and the first rotating shaft 110 is sequentially passed through the first mounting plate 130, the snap-fit ​​member 210 and the second mounting plate 140.

[0051] Specifically, a bearing can be provided on the inner side of the first mounting plate 130 and the second mounting plate 140, and both ends of the first rotating shaft 110 are rotatably engaged with the bearings. The first rotating shaft 110 can be a screw, with one end of the screw extending through the first mounting plate 130, the second mounting plate 140, and the snap-fit ​​member 210, and limited by a locking nut.

[0052] The snap-fit ​​component 210 is inserted into the installation space 150. On the one hand, it can improve the installation strength with the mounting support 10. On the other hand, it can shorten the total length of the entire fixing mechanism. Furthermore, the first mounting plate 130 and the second mounting plate 140 can absorb loads from different directions where the axial angle of the first rotating shaft 110 is set, avoiding excessive load transmission to the mounting support 10 and the mounting part 320 of the swing device, thereby improving the installation stability of the mounting support 10 and the swing device.

[0053] Furthermore, the mounting component 220 includes a first mounting component 221 and a second mounting component 222. One end of the first mounting component 221 is rotatably engaged with the snap-fit ​​component 210, one end of the second mounting component 222 is rotatably engaged with the other end of the first mounting component 221, and the other end of the second mounting component 222 is connected to the connector 30.

[0054] The first mounting component 221 and the second mounting component 222 are rotatably connected, and the first mounting component 221 is rotatably connected to the snap-fit ​​component 210. Multiple movable mechanisms can be set along the load transmission path from the wire rope 50 to the mounting support 10, so as to facilitate the sequential absorption of the load and reduce the load transmitted to the mounting support 10.

[0055] Specifically, the first mounting component 221 includes at least one mounting unit 223 arranged side by side, each mounting unit 223 having at least one mounting position; the second mounting component 222 includes at least one mating unit 224, the number of mating units 224 corresponding one-to-one with the mounting positions, and each mating unit 224 rotatably mating with the first mounting component 221 via a third rotating shaft 225.

[0056] The following description uses two mounting units 223, each with two mounting positions, and the second mounting component 222 having four mating units 224 as an example.

[0057] Each of the four mating units 224 requires four third shafts 225, and each third shaft 225 is installed and operates independently. When multiple wire ropes 50 require only one mating unit 224 to meet their support requirements, only one mating unit 224 needs to be selected. When two mating units 224 are required, one mounting unit 223 can be selected for installation. The other mounting unit 223 is in a non-working state at this time. If the current mounting unit 223 is damaged and needs to be replaced, two third shafts 225 can be directly installed, and then the third shaft 225 at the previous mounting unit 223 can be removed, making replacement more convenient. If three or four mating units 224 are required to support the wire ropes 50, then three or four third shafts 225 can be installed accordingly. The installation method between the first mounting component 221 and the second mounting component 222 is very convenient, meets the needs of different loads, and has a wider range of applications.

[0058] In one embodiment, the connector 30 is threadedly detachably connected to the second mounting member 222 and the second transition member 40.

[0059] That is, the two opposite ends of the connector 30 are provided with external threads, and the second mounting part 222 and the second transition part 40 are provided with holes that mate with the connector 30, and these holes are provided with internal threads that mate with the external threads. With this configuration, using the connector 30 as the dividing line, when some parts are damaged and need to be replaced, the connector 30 and its adjacent ends can be disassembled to avoid affecting other parts. In this way, the replacement of some parts does not require the replacement of the entire fixing mechanism, which improves the replacement efficiency and saves maintenance and replacement costs.

[0060] In one embodiment, the connector 30 is a connecting rod, which includes a first connecting part 310, a mounting part 320, and a second connecting part 330. The mounting part 320 is connected to the first connecting part 310 and the second connecting part 330 by a threaded connection. The first connecting part 310 is detachably connected to the first transition member 20, and the second connecting part 330 is detachably connected to the second transition member 40.

[0061] It should be noted that during actual disassembly and assembly, the mounting part 320 can be disassembled and assembled with the first connecting part 310 and the second connecting part 330 first, thereby avoiding the torque generated during disassembly and assembly from affecting the first transition piece 20 and the second transition piece 40.

[0062] In one embodiment, the second transition member 40 includes a plurality of limiting grooves 420, with a partition 430 between adjacent limiting grooves 420, and the second rotating shaft 410 is sequentially inserted through the limiting grooves 420 and the partition 430.

[0063] Setting up the partition 430 can prevent wear between adjacent wire ropes 50 and limit the movement of the wire rope 50 itself, preventing excessive swaying of the wire rope 50.

[0064] Specifically, this section uses four steel wire ropes 50 as an example. Each of the four steel wire ropes 50 is installed and secured within the limiting groove 420, with one end sleeved on the outside of the second rotating shaft 410. Therefore, the steel wire ropes 50 and the second rotating shaft 410 are in rotatable engagement. The number of steel wire ropes 50 is related to the actual load they bear; different numbers of steel wire ropes 50 can be set according to different loads. The specific number is not limited here.

[0065] In summary, the fixing mechanism for the multi-wire rope pulley of the present invention has an axial angle between the first rotating shaft 110 and the second rotating shaft 410. Therefore, the loads from different directions brought by the wire rope 50 can be absorbed by the movable cooperation between the mounting support 10 and the first transition member 20 and between the second transition member 40 and the wire rope 50. This results in higher installation strength, more uniform force distribution, and better safety between the mounting support 10 and the swing device body. Furthermore, multiple sets of wire ropes 50 are connected to the second transition member 40, thereby saving space while meeting the driving requirements of different loads.

[0066] The present invention also provides a multi-wire rope auxiliary drive device, comprising: multiple wire ropes 50 and the above-mentioned fixing mechanism for the multi-wire rope pulley, wherein the multiple wire ropes 50 are connected to the fixing mechanism for the multi-wire rope pulley.

[0067] When the wire rope 50 is subjected to force and sways, the resulting load is absorbed by the first rotating shaft 110 and the second rotating shaft 410, which avoids excessive impact on the mounting side of the mounting support 10 and the swing device body, and improves the installation stability between the mounting support 10 and the swing device body.

Furthermore, certain features, structures, or characteristics in one or more embodiments of the application can be appropriately combined.
