The guide limiting component is used to limit and guide the accompanying cable 1, and the buffering anti-swing component is used to buffer the accompanying cable 1 to prevent it from shaking. The quick-locking positioning component is used to be quickly assembled on the accompanying cable 1. When in use, the cable can be used to limit and guide the accompanying cable 1 through the guide limiting component, and the buffering anti-swing component is used to buffer the accompanying cable 1 to prevent it from shaking. The quick-locking positioning component is used to be quickly assembled on the accompanying cable 1. It has a simple structure and is easy to operate, which is convenient for the staff to quickly unlock the component assembly, allowing the staff to inspect and maintain the various components and the accompanying cable 1, reducing the workload of the staff and improving work efficiency.

[0025] In this embodiment, if Figure 1 、 Figure 3 and Figure 4 As shown, the quick-lock positioning assembly includes a spring-pressing assembly and a torsion assembly. The spring-pressing assembly includes two groups of bottom plates 3. The top ends of the two groups of bottom plates 3 are overlapped with supporting plates 4. The tops of the two groups of supporting plates 4 are overlapped with counterweight blocks 16. The bottoms of the supporting plates 4 are installed with rubber pads 17. The top ends of the supporting plates 4 are provided with docking holes extending to the inside of the rubber pads 17. The bottom ends of the counterweight blocks 16 are located at the docking holes and are installed with card blocks 5. The top of the bottom plate 3 is provided with a card slot corresponding to the docking hole. The card block 5 is slidably connected to the card slot. The inside of the bottom plate 3 is located in the card slot. A locking groove is provided on one side, and a rotating rod 6 is rotatably connected to the inner side of the locking groove. A spring block 7 is provided on the outer side of the rotating rod 6. A connecting groove is provided on one side of the spring block 7. A fixing plate 8 is installed on one side of the inner wall of the locking groove. A connecting spring 9 is installed between the inner wall of the connecting groove and the fixed plate 8. The fitting surfaces of the card block 5 and the spring block 7 are both provided with a first slope 10 that fits each other. First, place the two sets of base plates 3 on the main body of the accompanying cable 1, and then place the support plate 4 on the base plate 3, and then place the counterweight block 16 on it to allow the card block 5 to enter the inner side of the card slot.

[0026] In this embodiment, if Figure 1 、 Figure 3 and Figure 4As shown, a retraction groove is provided inside the spring block 7 at its first slope 10, and an abutment rod is rotatably connected to the inside of the retraction groove. An abutment plate 11 is sleeved on the outside of the abutment rod, and a return torsion spring 12 is installed between the abutment rod and the inner wall of the retraction groove. An abutment groove is provided inside the clamping block 5 at its first slope 10, and a second slope 13 is provided on one side of the abutment plate 11 to correspond to the first slope 10. Then, the counterweight 16 is slightly squeezed, and as the rubber pad 17 retracts, the clamping block 5 enters the inner side of the locking groove and contacts the spring block 7, and the first The slopes 10 squeeze each other, forcing the spring block 7 to rotate around the rotating rod 6, and the connecting spring 9 is stretched accordingly. After the blocking block 5 contacts the abutment plate 11, the first slope 10 and the second slope 13 fit and squeeze each other, forcing the abutment rod to drive the reset torsion spring 12 to retract, allowing the abutment plate 11 to completely retract to the inside of the retraction groove. Until the abutment groove is close to the retraction groove, the abutment plate 11 is ejected to the inside of the abutment groove by the reset torsion spring 12. At this time, the counterweight block 16 is released, and the rubber pad 17 rebounds to drive the blocking block 5 to move back the abutment plate 11 and fix it tightly against the inner wall of the abutment groove, completing the quick docking.

[0027] In this embodiment, if Figure 1 、 Figure 3 and Figure 4 As shown, the torsion assembly includes a limit groove provided on one side of the inner wall of the locking groove, and the end of the spring block 7 away from the first slope 10 is equipped with a limit plate 14 slidably connected to the limit groove, and both ends of the outer wall of the bottom plate 3 are provided with extension grooves, and the end of the rotating rod 6 extending to the inner side of the extension groove is equipped with a first knob 15. Furthermore, when it is necessary to release the connection for inspection and maintenance, twisting the first knob 15 can drive the rotating rod 6 to rotate accordingly, actively driving the spring block 7 to rotate, and the abutment plate 11 is dragged away from the inner wall of the abutment groove. At this time, the rubber pad 17 is completely reset and rebounded, and the block 5 continues to move. After the abutment groove and the retraction groove are misaligned, the abutment plate 11 will no longer be stuck in the inner side of the abutment groove. By removing the fitted counterweight block 16, the various components can be separated from the accompanying cable 1 for inspection and maintenance operations.

[0028] In this embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, the guide and limiting assembly includes waist holes 18 opened at both ends of the inner side of the support plate 4, a screw is slidably connected to the inner side of the waist hole 18, a nut is threadedly connected to the outer side of the screw, and a limiting wheel 19 is sleeved on the outer side of the screw, and the opposite surfaces of the two adjacent sets of limiting wheels 19 are in contact with the outer wall of the guide rope 2, and the buffering and anti-swaying assembly includes mounting columns 20 installed at both ends of the bottom of the base plate 3, and a synchronous groove is opened at the inner bottom end of the mounting column 20, and a synchronous plate is slidably connected to the inner side of the synchronous groove, and a spring damping shock absorber 21 is installed between the synchronous plate and the inner wall of the synchronous groove, and a connecting frame 22 is installed at one end of the synchronous plate, and a buffer roller 23 is rotatably connected between the two sets of connecting frames 22. Furthermore, when the traveling cable 1 swings, the outer wall of the traveling cable 1 contacts the outer wall of the buffer roller 23 in the swinging direction, and the buffer roller 23 rolls under the force, thereby unloading part of the force. At the same time, the connecting frame 22 is driven, so that the synchronous block slides inside the synchronous groove, squeezing the spring damping shock absorber 21, further unloading the force and reducing the swing amplitude.

[0029] The implementation principle of an elevator accompanying cable assembly in the embodiment of the present application is as follows: two sets of base plates 3 are placed on the accompanying cable 1 main body, and then the supporting plate 4 is placed on the base plate 3, and then the counterweight block 16 is placed on it to allow the clamping block 5 to enter the inner side of the clamping groove and slightly squeeze the counterweight block 16. As the rubber pad 17 retracts, the clamping block 5 enters the inner side of the locking groove and contacts the spring block 7. The first slopes 10 on the two squeeze each other, forcing the spring block 7 to rotate around the rotating rod 6, and the connecting spring 9 is stretched accordingly. After the clamping block 5 contacts the abutment plate 11, the first slope 10 and the second slope 13 fit together and squeeze each other, forcing the abutment rod to drive the reset torsion spring 12 to retract, allowing the abutment plate 11 to completely retract to the inside of the retraction groove. Until the abutment groove is close to the retraction groove, the abutment plate 11 is popped out to the inside of the abutment groove by the reset torsion spring 12. At this time, the counterweight block 16 is released, and the rubber pad 17 rebounds and drives the clamping block When the cam 11 is in the process of being disassembled, the first lever 15 is rotated and the second lever 16 is rotated, and the spring block 7 is rotated, and the cam 11 is pulled away from the inner wall of the cam 11. At this time, the rubber pad 17 is completely reset and rebounds, and the clamping block 5 continues to move. After the cam 11 is dislocated from the retraction groove, the cam 11 will no longer be stuck in the inner side of the cam 11. The fitted counterweight 16 is removed, and the various components can be separated from the accompanying cable 1 for maintenance and inspection. When the accompanying cable 1 swings, the outer wall of the accompanying cable 1 contacts the outer wall of the buffer roller 23 in the swinging direction. The buffer roller 23 rolls under the force, unloading part of the force. At the same time, the connecting frame 22 is driven, causing the synchronous block to slide inside the synchronous groove, squeezing the spring damping shock absorber 21, further unloading the force, and reducing the swing amplitude.
