Description

Technical Field

[0001] This utility model relates to the field of winch device technology, and in particular to a winch device for a clearing vehicle. Background Technology

[0002] Wreckers are specialized roadside assistance vehicles, primarily used for towing broken-down or accident-damaged vehicles or clearing road obstacles. Their core components include winches, towing arms, and flatbeds, enabling them to perform traction, lifting, and dragging operations. Based on function, they are categorized into flatbed and towing / lifting types. Some models are equipped with electric winches and intelligent control systems, featuring automated cable reeling and unloading, and remote control functions. They can adapt to various road conditions and rescue needs, making them crucial equipment for ensuring smooth road traffic.

[0003] For example, Chinese utility model patent with publication number CN222846361U can solve the problem of tangled and loose wire ropes on the drum of the winch when winding and unwinding the rope. However, during the winding and unwinding process, the wire rope will move laterally as the amount of cable increases or decreases. Since the rollers A and B in the device are flat as a whole, friction will occur when the wire rope moves, resulting in a sharp reduction in life and failing to reduce friction during the winding and unwinding process. In view of this, we propose a winch device for a clearing vehicle. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a winch device on a clearing vehicle, including a clearing vehicle 1. Two first mounting plates 2 are fixedly connected to the upper surface of the clearing vehicle 1. Two rollers 3 are rotatably connected between the two first mounting plates 2. Guide grooves 4 are provided on the two rollers 3. Two second mounting plates 5 are fixedly connected to the upper surface of the clearing vehicle 1. A winding roller 6 is rotatably connected between the two second mounting plates 5. A U-shaped mounting plate 7 is fixedly connected to the right surface of the two second mounting plates 5. A clearance groove 8 is provided on the left surface of the U-shaped mounting plate 7. Two first guide wheels 9 are rotatably connected between the upper and lower inner walls of the clearance groove 8. A through groove communicating with the interior of the clearance groove 8 is provided on the right surface of the U-shaped mounting plate 7. A lead wire tube 10 is fixedly connected to the right surface of the U-shaped mounting plate 7. A guide component is provided on the U-shaped mounting plate 7. By setting the two first guide wheels 9, the wire rope passes through a fixed point during the wire release and reeling process, effectively avoiding the problem of the wire rope shifting back and forth, which leads to friction and reduced service life.

[0024] Furthermore, the guiding assembly includes four third mounting plates 11, which are respectively fixedly connected to the upper and lower surfaces of the U-shaped mounting plate 7. A threaded rod 12 is rotatably connected between the two upper third mounting plates 11, and a guide rod 13 is fixedly connected between the two lower third mounting plates 11. A displacement plate 14 is slidably sleeved on the outer surface of the guide rod 13, and a displacement plate 14 is threadedly sleeved on the outer surface of the threaded rod 12. Two second guide wheels 15 are rotatably connected between the two displacement plates 14. A first sprocket 16 is rotatably connected to the front surface of the take-up roller 6, and a first sprocket 16 is also rotatably connected to the front surface of the upper third mounting plate 11. A first chain is meshed between the two first sprockets 16. 17. A second sprocket 18 is fixedly connected to the front surface of the first sprocket 16 on the right side. A second sprocket 18 is also rotatably connected to the front surface of the first mounting plate 2. A second chain 19 is meshed between the two second sprockets 18. The first sprocket 16 on the left side is connected to the winding roller 6. A ratchet one-way overrunning clutch is provided on the front surface of the roller 3. The first sprocket 16 on the right side is connected to the threaded rod 12. The second sprocket 18 on the right side is connected to the input end of the ratchet one-way overrunning clutch. Through the cooperation of the second guide wheel 15 and the threaded rod 12, the wire rope can be aligned with the two second guide wheels 15 during winding and unwinding. This not only serves as a guide but also avoids the problem of misalignment caused by a large tilt angle of the wire rope.

[0025] The take-up roller 6 is connected to an external drive source such as an electric motor, while the ratchet one-way overrunning clutch is existing technology. For details, please refer to patent publication number CN222846361U. Since it is not the main direction of improvement, it will not be described in detail here.

[0026] Working principle: During operation, the take-up roller 6 is first driven to rotate by an external drive source. When the take-up roller 6 rotates, it simultaneously drives the threaded rod 12 to rotate with the cooperation of two first sprockets 16 and the first chain 17. When the threaded rod 12 rotates, the two displacement plates 14 are connected by the second guide wheel 15. The movement trajectory of the lower displacement plate 14 is restricted by the guide rod 13. Therefore, when the threaded rod 12 rotates, it simultaneously drives the displacement plate 14 to move horizontally. When the displacement plate 14 moves, it simultaneously drives the second guide wheel 15 to move, thereby aligning the point where the wire rope leaves the take-up roller 6 with the center of the two second guide wheels 15. After being guided by the two second guide wheels 15, it enters the first guide wheel 9 and finally enters the interior of the guide groove 4 through the lead tube 10. This ensures that the wire rope remains aligned with the guide groove 4 during both the unwinding and take-up processes, avoiding friction caused by wire deviation. At the same time, when the first sprocket 16 rotates, it also cooperates with the second sprocket 18, the second chain 19, and the ratchet one-way overrunning clutch to drive the roller 3 to rotate, thereby preventing slack during unwinding.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
