Technical Field
[0001] This utility model relates to the field of electric winch technology, specifically to a vehicle-mounted fixed-tension electric winch. Background Technology
[0002] An electric winch is a traction device used for self-protection of vehicles or vessels. Electric winches can be installed on military engineering vehicles, trailers, rescue vehicles, and various rescue and repair vehicles, as well as on police or civilian engineering vehicles, rescue vehicles, trailers, breakdown vehicles, and engineering machinery.
[0003] The announcement number CN218841540U discloses a vehicle-mounted constant-tension electric winch. A rotatable intermediate gear is mounted on the right side of the frame. A power take-off (PTO) device is mounted on the frame, and the motor output shaft of the PTO device is connected to the input shafts of two reducers. The motor drives the reducers to transmit force. A front friction drum and a rear friction drum are respectively mounted on the two reducers. The two reducers drive the front and rear friction drums to move at the same speed, thereby rotating the rope storage drum. A driven gear is mounted on the right side of the rope storage drum, and a differential mechanism is located to the right of the driven gear. One end of the wire rope is fixed to the rope storage drum, and the middle section is wound sequentially around the rope storage drum, the rear friction drum, and the front friction drum. This electric winch has a compact structure and simple control. By using a motor to transmit force to two reducers, it drives the front and rear friction drums to rotate, outputting a constant traction force to ensure smooth and reliable rope winding and unwinding under load.
[0004] After a rescue operation, the electric winch in this device typically winds the cable directly onto the winch surface. However, during the rescue process, the cable surface is often covered with mud and dirt. This mud and dirt accumulates on the inside of the cable over a long period of time, which can easily corrode the cable, causing quality problems and increasing the risk of breakage during the rescue, thus reducing its safety.
[0005] Therefore, it is necessary to invent a vehicle-mounted fixed-tension electric winch to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a vehicle-mounted fixed-tension electric winch to solve the problem that mud and dirt accumulate on the inside of the cable for a long time, which can easily cause corrosion to the cable, leading to problems with the quality of the cable, the risk of breakage during rescue operations, and reduced safety.

Detailed Implementation
[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0030] This utility model provides, for example Figure 1 and Figure 2 The vehicle-mounted fixed tension electric winch shown includes a frame body 1. An equipment bracket 11 is fixedly connected to the right side of the frame body 1. A winding reel 14 is rotatably connected inside the equipment bracket 11. A cable 15 is wound on the surface of the winding reel 14. A reducer 12 is fixedly installed on the front surface of the equipment bracket 11. A bidirectional motor 13 is fixedly installed at the front end of the reducer 12. The output end of the bidirectional motor 13 is fixedly connected to the input end of the reducer 12. The output end of the reducer 12 is fixedly connected to the front end of the winding reel 14. A guide bracket 2 is fixedly connected to the right side of the equipment bracket 11. Guide rings 21 are fixedly connected to both the left and right sides of the guide bracket 2. The right end of the cable 15 passes through two sets of guide rings 21 in sequence. A hook is fixedly connected to the right end of the cable 15.
[0031] The reducer 12 is used to reduce the power of the bidirectional motor 13 by meshing a gear with fewer teeth on the input shaft with a large gear on the output shaft. This reduces the speed and increases the output torque. The torque output ratio is the motor output multiplied by the reduction ratio, but it is important to note that it should not exceed the rated torque of the reducer 12. The bidirectional motor 13 and the reducer 12 work together to drive the winding reel 14 to rotate. When the output end of the bidirectional motor 13 rotates forward, it drives the winding reel 14 to rotate forward, thereby winding the cable 15. When the output end of the bidirectional motor 13 rotates backward, it drives the winding reel 14 to rotate backward, thereby unwinding the cable 15.
[0032] Specifically, during use, the bidirectional motor 13 is first reversed to release the cable 15 and the hook is hung on the equipment. Then, the bidirectional motor 13 rotates forward to wind up the cable 15, pulls the equipment, and rescues the vehicle.
[0033] See Figures 2 to 4The guide bracket 2 has a cleaning module inside, which includes an electric motor 23, a transmission gear 24, a support block 3, a rotating ring 32, a connecting rod 34, a cleaning ring 35, a cleaning brush 36, and a transmission gear ring 37. A mounting plate 22 is fixedly connected to the upper surface of the guide bracket 2. The electric motor 23 is fixedly mounted on the right side surface of the mounting plate 22. The transmission gear 24 is fixedly connected to the output end of the electric motor 23. Support blocks 3 are fixedly connected to both the left and right sides inside the guide bracket 2. The ends of the two sets of support blocks 3 that are close to each other are fixedly mounted. A fixed connection limit ring 31 is provided. A rotating ring 32 is provided at the close end of each of the two sets of support blocks 3. A limit groove 33 is opened on the inner wall of the rotating ring 32. The limit ring 31 is stuck in the limit groove 33 and rotatably connected to the limit groove 33. The transmission gear ring 37 is fixedly connected to the surface of the rotating ring 32 and meshes with the transmission gear 24. Multiple sets of connecting rods 34 are fixedly connected between the two sets of rotating rings 32. Multiple sets of cleaning rings 35 are fixedly connected to the surface of the connecting rods 34. A cleaning brush 36 is fixedly connected to the inner wall of the cleaning ring 35.
[0034] In addition, during use, the cable 15 passes through the inner side of the support block 3, the rotating ring 32, and the cleaning ring 35 in sequence. The cleaning brush 36 on the inner side of the cleaning ring 35 abuts against the surface of the cable 15. During the winding of the cable 15, the electric motor 23 is started at the same time. The output end of the electric motor 23 drives the transmission gear 24 to rotate. The transmission gear 24 drives the transmission gear ring 37 to rotate. At this time, with the cooperation of the limiting ring 31 and the limiting groove 33, the transmission gear ring 37 drives the left rotating ring 32 to rotate at the end of the support block 3. At this time, the left rotating ring 32 drives multiple sets of connecting rods 34 and the right rotating ring 32 to rotate. The connecting rods 34 drive multiple sets of cleaning rings 35 to rotate. The cleaning rings 35 drive the inner cleaning brush 36 to rotate, cleaning the surface of the cable 15 and improving the cleanliness of the cable 15 surface.
[0035] The working principle of this utility model is as follows: During the winding process of the cable 15, the electric motor 23 drives the rotating ring 32 to rotate through the transmission gear 24 and the transmission gear ring 37. The rotating ring 32 drives the cleaning ring 35 and the cleaning brush 36 to rotate, thereby cleaning the surface of the cable 15, improving the cleanliness of the cable 15 surface, reducing the erosion of the cable 15 by mud and dirt, and improving the safety of the cable 15 in use.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
