Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an electric winch for preventing rope loosening. Background Technology

[0002] In numerous industrial, engineering, and outdoor work scenarios, electric winches play an indispensable role as a key traction and lifting device. For example, in the field of car rescue, when vehicles are stuck in mud, sand, or snow, electric winches, with their strong pulling force, can use ropes to pull the trapped vehicles out of trouble. In construction sites, they are used to hoist building materials to higher work surfaces, helping to advance the construction process efficiently. In maritime scenarios, they assist small boats in docking and raising anchors.

[0003] Loose ropes exacerbate friction between the winch drum, rope guide, and the rope, accelerating wear on these components. With prolonged and frequent use, the drum may experience uneven wear in the grooves, and the rope guide may deform. This not only reduces the equipment's lifespan but also increases maintenance costs and downtime. For example, in port lifting operations, frequent rope loosening significantly increases the frequency of winch maintenance, severely impacting normal terminal operations. In logistics transportation, electric winches are commonly used for loading and unloading containers. If the rope is loose, the rope winding and unwinding process becomes extremely difficult, sometimes resulting in the rope getting stuck in container gaps. Workers are forced to stop their work and spend considerable time clearing the tangled rope, significantly extending the time required to load or unload a container and delaying the overall logistics progress. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an electric winch that prevents the rope from becoming loose, aiming to improve the problem in the prior art where if the pull rope becomes loose, it will drag on the ground during movement, causing friction with the ground and seriously affecting the service life of the pull rope.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electric winch for preventing rope loosening, comprising a hollow shell and a hook, a second support plate fixedly connected to the right side of the hollow shell, a motor fixedly connected to the inner wall of the hollow shell, a rotating column fixedly connected to the output end of the motor, a hanging rod slidably connected to the right side of the outer wall of the second support plate, a connecting block fixedly connected to the bottom end of the hook, a connecting column rotatably connected to the inner wall of the hook, a rotating block fixedly connected to the outer wall of the connecting column, a torsion spring fixedly connected to the inner wall of the rotating block, and an auxiliary mechanism provided on the right side of the hollow shell for disassembling and replacing the rope.

[0006] As a further description of the above technical solution:

[0007] The auxiliary mechanism includes a limiting ring, the inner wall of which is threadedly connected to the outer wall of the hanging rod. Telescopic rods are fixedly connected to the front and rear sides of the hollow shell. A push plate is fixedly connected to the right side of the telescopic rod. A fixing plate is slidably connected to the right side of the outer wall of the rotating column. A screw is threadedly connected to the outer wall of the fixing plate. A support plate is threadedly connected to the right side of the outer wall of the screw.

[0008] As a further description of the above technical solution:

[0009] The bottom end of the second support plate is fixedly connected to the first base plate, and the right end of the hanging rod is fixedly connected to the stop block.

[0010] As a further description of the above technical solution:

[0011] The bottom end of the support plate one is fixedly connected to the base plate two, and the outer wall of the rotating column is rotatably connected to the pull rope.

[0012] As a further description of the above technical solution:

[0013] A fixing column is fixedly connected to the right side of the support plate, and an identification mark is fixedly connected to the outer wall of the fixing column.

[0014] As a further description of the above technical solution:

[0015] The right side of the second support plate is rotatably connected to the rotating column, and a protective sleeve is fixedly connected to the left side of the hollow shell.

[0016] As a further description of the above technical solution:

[0017] The top of the hollow shell is rotatably connected to a handle, and the outer wall of the handle is fixedly connected to an anti-slip sleeve.

[0018] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the pull rope is fixed to the bottom of the connecting block, the hook is hung on the hanging rod, the hanging rod pushes the rotating block to rotate around the connecting column and compresses the torsion spring. After the hanging rod enters the hook, the torsion spring makes the rotating block return to its original position. Then the motor is started, the motor makes the pull rope close to the outer wall of the rotating column, the hook is locked on the outer wall of the hanging rod, and the pull rope will be tightened to prevent the pull rope from loosening or even dragging on the ground during the movement of the equipment, which would lead to wear of the pull rope and affect the service life of the pull rope.

[0022] 2. In this utility model, when disassembling and replacing the pull rope, first turn the limiting ring to separate it from the hanging rod, then pull out the hanging rod, then turn the screw to disengage it from the inner wall of the support plate, push the fixing plate and the support plate out together, and finally start the telescopic rod to push the push plate to the right to push the pull rope out from the outer wall of the rotating column. This can realize the disassembly and replacement of the pull rope, and prevent the pull rope from being worn due to prolonged use and unable to withstand greater tension. Attached Figure Description

[0038] Specifically, the marking 17 facilitates quick identification and operation by the user; the screw 204 is threadedly connected to the support plate 206, ensuring the stability and durability of the connection; and the hanging rod 6 is slidably connected to the support plate 206, which not only improves the flexibility of the device but also allows the user to adjust the position of the hanging rod 6 as needed.

[0039] Working principle: Tie the pull rope 14 to the bottom of the connecting block 8, and then hang the hook 7 on the hanging rod 6. The hanging rod 6 will squeeze the rotating block 11, causing the rotating block 11 to rotate around the connecting column 9 and compress the torsion spring 10. When the hanging rod 6 enters the inside of the hook 7, the torsion spring 10 will push the rotating block 11, causing the rotating block 11 to return to its original position. Then start the motor 5. During the rotation of the motor 5, the pull rope 14 will be tightly pressed against the outer wall of the rotating column 4. Since one end of the hook 7 is stuck on the outer wall of the hanging rod 6, the pull rope 14 will be tightened to prevent the pull rope 14 from loosening or even dragging on the ground during the movement of the equipment, which would cause wear on the pull rope 14 and affect its service life.

[0040] To disassemble and replace the pull rope 14, turn the limiting ring 201 to separate it from the hanging rod 6, allowing the hanging rod 6 to be pulled out. Then, turn the screw 204 to disengage it from the inner wall of the support plate 206 and push the fixing plate 205 to push it out together with the support plate 206. Finally, activate the telescopic rod 202, which will push the push plate 203 to the right. As the push plate 203 moves to the right, it will push the pull rope 14 out from the outer wall of the rotating column 4, thus enabling the disassembly and replacement of the pull rope 14. This prevents the pull rope 14 from becoming worn due to prolonged use and unable to withstand greater tension.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
