Abstract
Description
Technical Field
[0001] This utility model relates to the field of low-voltage engineering construction technology, specifically a cable unwinding device for low-voltage engineering construction. Background Technology
[0002] Low-voltage electrical engineering is an important branch of power applications. It mainly deals with the transmission and control of low-voltage and low-current electrical signals, covering multiple fields such as communication, security, and intelligent systems. It is widely used in modern buildings and infrastructure.
[0003] A cable unwinding device for power transmission and transformation engineering construction, disclosed in CN220484887U, uses a spring to pull a push plate, which pushes a chuck rod to insert into the chuck groove. This effectively restricts the rotation of the rotating shaft, preventing the moving wheel from rotating and increasing friction by keeping it in contact with the ground. When used in conjunction with a support frame, the support frame is less likely to be dragged after placement, improving its stability. This eliminates the need for workers to monitor the unwinding device, reducing the workload of auxiliary personnel. Furthermore, the unwinding device does not require support and is less prone to displacement.
[0004] The cable unwinding device used in this power transmission and transformation project can facilitate the unwinding and rewinding of cables by workers through its chuck structure. However, when rewinding cables, workers need to manually rotate the rewinding disc, which affects work efficiency and is quite troublesome. Therefore, it needs to be improved. Utility Model Content

[0025] This utility model provides the following technical solution:
[0026] Example 1
[0027] Please see Figure 1-4 This utility model provides a technical solution: a cable unwinding device for low-voltage engineering construction, including a movable frame 1, a handle 5 fixedly connected to the right side of the movable frame 1, a wire unwinding roller 4 rotatably connected to the inner side of the movable frame 1, an insert plate 6 fixedly connected to the front of the wire unwinding roller 4, a rotating mechanism 2 provided on the front of the movable frame 1, and an auxiliary mechanism 3 provided on the front of the rotating mechanism 2.
[0028] The rotating mechanism 2 includes a fixed frame 21, which is fixedly connected to the front of the movable frame 1. A drive motor 22 is fixedly connected to the front of the fixed frame 21. A rotating shaft 24 is fixedly connected to the back of the drive motor 22. A rotating frame 25 is fixedly connected to the back of the rotating shaft 24. A sliding plate 23 is slidably connected to the inner side of the rotating frame 25. A linkage frame 26 is rotatably connected to the inner side of the movable frame 1. A connecting plate 27 is fixedly connected to the front of the linkage frame 26.
[0029] Furthermore, the front of the movable frame 1 and the inner side of the linkage frame 26 are provided with slots corresponding to the movement trajectory of the insert plate 6, and the insert plate 6 is inserted into the slot. Through the slots, the insert plate 6 can be inserted into the inner side of the movable frame 1 and the linkage frame 26, so that when the connecting plate 27 rotates, it can drive the linkage frame 26 and the insert plate 6 to rotate, and the insert plate 6 can drive the feed roller 4 to rotate.
[0030] Furthermore, a circular groove corresponding to the movement trajectory of the linkage frame 26 is provided on the inner side of the movable frame 1, and the linkage frame 26 is slidably connected to the inside of the circular groove. Through the circular groove, the linkage frame 26 can rotate inside the movable frame 1.
[0031] Furthermore, a fixing hole corresponding to the position of the rotating shaft 24 is provided on the inner side of the fixing frame 21, and the rotating shaft 24 is rotatably connected to the inner side of the fixing hole. Through the fixing hole, the rotating shaft 24 can rotate inside the fixing frame 21, so that when the drive motor 22 is running, it can drive the rotating frame 25 to rotate through the rotating shaft 24.
[0032] Example 2
[0033] Please see Figure 1-4 Furthermore, based on Embodiment 1, the auxiliary mechanism 3 includes a hydraulic cylinder 31, which is fixedly connected to the front of the fixed frame 21. A push plate 32 is fixedly connected to the back end of the hydraulic cylinder 31. An arc-shaped slider 35 is fixedly connected to the inner side of the push plate 32. A telescopic rod 36 is fixedly connected to the back end of the slide plate 23. A rectangular block 33 is fixedly connected to the back end of the telescopic rod 36. The rectangular block 33 is slidably connected to the inner side of the rotating frame 25. The rectangular block 33 is inserted into the inner side of the connecting plate 27. A spring 34 is sleeved around the telescopic rod 36.
[0034] Furthermore, the back end of the spring 34 is fixedly connected to the front end of the rectangular block 33, and the front end of the spring 34 is fixedly connected to the back end of the slide plate 23. Through the elastic force of the spring 34, the spring 34 can drive the rectangular block 33 to move, so that the rectangular block 33 can be inserted into the connecting plate 27.
[0035] Furthermore, a sliding groove corresponding to the movement trajectory of the arc-shaped slider 35 is provided on the inner side of the slide plate 23, and the arc-shaped slider 35 is slidably connected to the inside of the sliding groove. Through the sliding groove, the arc-shaped slider 35 can slide on the inner side of the slide plate 23, so that when the rotating frame 25 drives the slide plate 23 to rotate, it does not hinder the push plate 32 from moving back and forth.
[0036] In actual operation, when this device is used, the wire feeding roller 4 is placed inside the movable frame 1 so that the insert plate 6 on the front of the wire feeding roller 4 can be inserted into the movable frame 1 and the linkage frame 26. When it is necessary to feed the low-voltage engineering cable, the staff manually pulls the low-voltage cable so that the feeding roller can rotate inside the movable frame 1 to realize the wire feeding function.
[0037] After the low-voltage cables are laid, the worker turns on the hydraulic cylinder 31, causing it to push the push plate 32. This allows the push plate 32 to move the telescopic rod 36 and the rectangular block 33, enabling the rectangular block 33 to insert into the connecting plate 27. If the rectangular block 33 cannot be inserted into the connecting plate 27, it will compress the spring 34. The worker then slowly rotates the cable laying roller 4, which, through the insert plate 6, drives the linkage frame 26 and the connecting plate 27 to rotate. This ensures that the opening on the front of the connecting plate 27 aligns with the rectangular block 33. If the connecting plate 27 is not aligned... When the rectangular block 33 is compressed, the elastic force of the spring 34 causes the telescopic rod 36 to drive the rectangular block 33 to insert into the connecting plate 27. The operator turns on the drive motor 22, which drives the rotating frame 25 to rotate through the rotating shaft 24. The rotating frame 25 drives the telescopic rod 36 and the rectangular block 33 to rotate through the sliding plate 23. The rectangular block 33 can drive the linkage frame 26 to rotate through the connecting plate 27. The linkage frame 26 can drive the wire feeding roller 4 to rotate in the opposite direction through the insert plate 6. The wire feeding roller 4 can automatically take back the excess low-voltage cables to prevent the low-voltage cables from getting tangled and knotted.
