Description

Technical Field

[0001] This utility model relates to the field of winch technology, specifically to a low-voltage cable winch. Background Technology

[0002] A cable winch is a mechanical device used for hoisting and transporting heavy objects. It mainly consists of a motor, a reducer, a brake, a winch drum, and a control system. Its working principle is that the motor drives the reducer to rotate, which in turn drives the winch drum to continuously wind up the cable, thereby completing the lifting and transportation of the construction object.

[0003] Once the cable has carried the work object to the target location, the cable rewinding stops. At this point, the weight of the work object pulls the cable downwards, causing excessive tension and potential damage, thus posing a safety hazard. Therefore, there is an urgent need to design a low-voltage cable winch to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a low-voltage cable winch to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A low-voltage cable winch includes a container, the middle of which is equipped with a partition wall. The interior of the container is divided into a winch functional area and a work area by the partition wall. The winch functional area is equipped with a winch frame and a plate. A winch roller is rotatably fitted on the inner side of the winch frame. Cables are wound around the periphery of the winch roller. A U-shaped frame is slidably fitted on the upper side of the plate.

[0007] The U-shaped frame is rotatably fitted with guide rollers on its inner sides. A bidirectional screw is rotatably fitted inside the guide rollers. Both ends of the bidirectional screw are threaded with annular clamps. Multiple springs are installed on the inner sides of the two annular clamps. Annular rubber plates are installed on one end of each spring. One end of the cable is slidably fitted around the periphery of the guide rollers and corresponds to the two annular rubber plates.

[0008] Furthermore, a groove is provided on the periphery of the guide roller, and the two annular clamps are slidably fitted in the groove. Rubber blocks are installed on the opposite inner sides of the groove, and the two rubber blocks are in contact with the inner sides of the two annular clamps.

[0009] Furthermore, a screw is rotatably fitted on the upper side of the plate, the circumference of the screw is threadedly fitted to the lower end of the U-shaped frame, and the two annular clamps and the two annular rubber plates are slidably fitted on the circumference of the guide roller.

[0010] Furthermore, a first motor is installed on one side of the U-shaped frame and one side of the plate. The output end of one of the first motors is fixed to one end of the bidirectional screw, and the output end of the other first motor is fixed to one end of the screw.

[0011] Furthermore, a second motor is installed on one side of the winch platform, the output end of the second motor is fixed to one end of the winch roller, and the other end of the cable is fixed to the periphery of the winch roller.

[0012] Furthermore, one side of the winch platform is equipped with a clutch, manual control device, power distribution frequency converter, and electrical control box corresponding to the winch roller, and the functional area of ​​the work area is equipped with a cabinet, tool cabinet, maintenance table, seat, axial flow fan, power distribution cabinet, and walkie-talkie.

[0013] Furthermore, one end of the partition wall has an opening, and a stainless steel fire door is rotatably fitted inside the opening. The bottom of the work area is a wooden base, and the bottom of the winch area is a stainless steel base.

[0014] In the above technical solution, the low-voltage cable winch provided by this utility model has the following beneficial effects:

[0015] The bidirectional screw is designed to engage with two annular clamps, thereby driving the two annular clamps to move relative to each other. The distance between the two annular clamps can be adjusted according to the cable size, thus clamping and fixing cables of different sizes. This supports and bears the downward force on the cable, effectively reducing cable damage caused by excessive tension and improving safety.

[0016] The two ring-shaped rubber plates allow for better contact with the cable surface, increasing friction and making the clamping of the cable more stable, while effectively reducing deformation and damage to the cable surface. Attached Figure Description

[0032] In this embodiment, a U-shaped frame 8 is slidably fitted on the upper side of the plate 6;

[0033] Specifically, a screw 16 is rotatably fitted on the upper side of the plate 6. The circumference of the screw 16 is threadedly engaged with the lower end of the U-shaped frame 8. The two annular clamping plates 11 and the two annular rubber plates 13 are slidably engaged with the circumference of the guide roller 9.

At this time, the other end of the cable is wound up, and one end of the cable slides around the circumference of the guide roller 9 and drives the guide roller 9 to rotate. Then start another first motor 17. The output end of the other first motor 17 drives the screw 16 to rotate, so that the screw 16 is threaded with the lower end of the U-shaped frame 8, thereby driving the U-shaped frame 8 to move horizontally on the upper side of the plate 6. The position can be kept consistent with the cable according to the degree of cable winding.

[0039] 2. When it is necessary to clamp and fix one end of the cable, start one of the first motors 17.
