Description

Technical Field

[0001] This utility model relates to the field of electric winch technology, specifically to an anti-rotation electric winch with a self-locking function. Background Technology

[0002] An electric winch is a power-driven traction device widely used in vehicle self-rescue, field operations, engineering rescue, and cargo loading and unloading. It uses a motor to drive the raising and lowering of a steel cable or rope, possessing strong traction and stable operating performance. Compared to manual winches, electric winches are labor-saving and efficient, especially suitable for complex terrain or heavy-duty tasks. The core components of an electric winch include a high-power motor, reducer, braking system, and control module; some models also feature wireless remote control functionality, enhancing ease of operation. They are typically compatible with various platforms such as off-road vehicles, trucks, ships, and fixed frames, becoming an indispensable auxiliary tool in outdoor adventure and industrial fields.

[0003] Chinese patent CN217323179U discloses a portable electric winch. Addressing the problem of existing technologies' inability to maintain electric winches during use, the patent proposes the following solution: It includes a first protective box and a second protective box. Multiple mounting plates are installed on the inner top wall of the second protective box, and a fixing plate is mounted on the top of these mounting plates. A mounting frame is placed on top of the fixing plate, and the electric winch is installed inside the mounting frame. A cover plate is hinged to one side of the top of the first protective box, and an oil inlet is installed on top of the cover plate. This electric winch, through the maintenance of the wire rope, not only extends the service life of the wire rope but also avoids the tediousness of manual maintenance, improving the portability of the device. Furthermore, the elastic pad, support plate, and second protective box provide a certain degree of protection, preventing damage to the electric winch from external impacts and extending its service life.

[0004] The electric winch described in the aforementioned patent uses a winch motor to drive the winch body to rotate, enabling the winch body to perform the winding and unwinding operations. However, the winch body is directly connected to the winch motor, and when the winch body is stationary, the winch body is entirely braked by the winch motor, making the winch motor prone to damage. Therefore, an anti-rotation electric winch with a self-locking function is proposed. Utility Model Content

[0005] To address the aforementioned issues, a self-locking anti-rotation electric winch is provided. When the two sets of moving frames move away from each other, the moving frames cause the brake pads to separate from the nut, thus releasing the nut. This allows the take-up roller to take in or release the wire. When the two sets of moving frames move closer together, the moving frames cause the brake pads to move synchronously. At this time, the moving frames clamp the nut on both sides through the brake pads, preventing the nut from rotating. This allows the nut to brake the take-up roller, solving the problem of rotation that occurs after the electric winch has finished taking in or releasing the wire.

[0006] To address the existing technical problems, this application provides an anti-rotation electric winch with a self-locking function, including a fixed frame, a take-up roller mounted on the fixed frame, and a braking mechanism mounted on the fixed frame. The take-up roller is horizontally mounted inside the fixed frame and can rotate. One end of the take-up roller can penetrate through the side of the fixed frame, and a brake pad is fixed to the outer end of the take-up roller.

[0007] The braking mechanism includes a fixed seat fixed to one side of the fixed frame. Inside the fixed seat are two sets of movable frames that can move closer to or further away from each other. Brake pads are fixed to the corresponding sides of the two sets of movable frames.

[0008] As one technical solution of this application, the movable frame is provided with threaded holes;

[0009] The fixed base is equipped with a threaded rod inside, which is threadedly engaged with a threaded hole, and a gear is fixed to the extended end of the threaded rod.

[0010] A slide rail is fixed on the outer wall of the fixed base, and a rack that slides on the slide rail is installed on the slide rail. One side of the rack meshes with a gear.

[0011] The fixed base is also fixed with a hydraulic cylinder for driving the rack to move along the central axis of the slide rail, and the output end of the hydraulic cylinder is fixedly connected to the rack.

[0012] As one technical solution of this application, slide rods are symmetrically fixed inside the fixed base near the inner side of the threaded rod;

[0013] The movable frame has sliding holes, which slide in conjunction with the sliding rod.

[0014] As one technical solution of this application, a protective cover for shielding the braking mechanism is installed on one side of the fixing frame.

[0015] As one technical solution of this application, a servo motor capable of driving the take-up roller to rotate is fixed on the side of the fixed frame away from the braking mechanism, and the output end of the servo motor is fixedly connected to the end of the take-up roller.

[0016] As one technical solution of this application, a controller is fixed on the top of the fixed frame, and the controller is electrically connected to the servo motor and the braking mechanism respectively.

[0017] The advantages of this utility model compared to the prior art are:

[0018] When the two sets of moving frames move away from each other, the moving frames cause the brake pads to separate from the nut, thus releasing the nut. This allows the take-up roller to take in or release the wire. When the two sets of moving frames move closer together, the moving frames cause the brake pads to move synchronously. At this time, the moving frames clamp the nut on both sides through the brake pads, preventing the nut from rotating. This allows the nut to brake the take-up roller. This solves the problem of the electric winch rotating back after taking in or releasing the wire. Attached Figure Description

Detailed Implementation

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0027] See Figures 1-6 As shown, an anti-rotation electric winch with self-locking function includes a fixed frame 1, a take-up roller 3 disposed on the fixed frame 1, and a braking mechanism 6 disposed on the fixed frame 1. The take-up roller 3 is horizontally installed inside the fixed frame 1 and can rotate. One end of the take-up roller 3 can penetrate through the side of the fixed frame 1, and a brake pad 31 is fixed to the outer end of the take-up roller 3.

[0028] The braking mechanism 6 includes a fixed seat 61 fixed to one side of the fixed frame 1. The fixed seat 61 has two sets of movable frames 64 that can move closer to or further away from each other. Brake pads 643 are fixed to the corresponding sides of the two sets of movable frames 64.

[0029] When the two sets of moving frames 64 move away from each other, the moving frames 64 will cause the brake pads 643 to separate from the nut 32, thereby releasing the nut 32. This allows the take-up roller 3 to take up or release the wire. When the two sets of moving frames 64 move closer to each other, the moving frames 64 will cause the brake pads 643 to move synchronously. At this time, the moving frames 64 will clamp the nut 32 on both sides through the brake pads 643, preventing the nut 32 from rotating. This allows the nut 32 to brake the take-up roller 3, solving the problem of the electric winch rotating back after taking up or releasing the wire.

[0030] See Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the movable frame 64 has a threaded hole 641.

[0031] A threaded rod 62 is installed inside the fixed base 61. The threaded rod 62 is threadedly engaged with the threaded hole 641. A gear 621 is fixed to the extended end of the threaded rod 62.

[0032] A slide rail 611 is fixed on the outer wall of the fixed base 61. A rack 66 is installed on the slide rail 611 and slides in cooperation with the slide rail 611. One side of the rack 66 meshes with the gear 621.

[0033] A hydraulic cylinder 65 is also fixed on the fixed base 61 to drive the rack 66 to move along the central axis of the slide rail 611. The output end of the hydraulic cylinder 65 is fixedly connected to the rack 66.

[0034] To enable effective movement of the movable frame 64, a threaded hole 641 is made in the movable frame 64, and then a threaded rod 62 is installed inside the movable frame 64. When the hydraulic cylinder 65 is activated, the hydraulic cylinder 65 drives the rack 66 to move along the central axis of the slide rail 611. At this time, the rack 66 drives the threaded rod 62 to rotate through the gear 621 meshing with it. As the threaded rod 62 rotates, it causes the movable frames 64 to move closer or further apart through the threaded hole 641 that is threaded with it.

[0035] See Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, slide rods 63 are symmetrically fixed inside the fixed base 61 near the inner side of the threaded rod 62;

[0036] The movable frame 64 has a sliding hole 642, which is slidably engaged with the slide rod 63.

[0037] To ensure the stability of the movable frame 64, a sliding hole 642 is made in the movable frame 64, and then the movable frame 64 is installed on the slide rod 63 through the sliding hole 642. When the movable frame 64 moves, the movable frame 64 will move along the central axis of the slide rod 63 through the sliding hole 642, so that the slide rod 63 and the sliding hole 642 cooperate to limit the movable frame 64, thereby ensuring the stability of the movable frame 64.

[0038] See Figure 1 As shown, a protective cover 2 for shielding the braking mechanism 6 is installed on one side of the fixing frame 1.

[0039] By fixing the protective cover 2 to one side of the mounting bracket 1, the protective cover 2 can cover the outside of the braking mechanism 6. This effectively prevents the braking mechanism 6 from being exposed, which not only improves the aesthetics of the electric winch but also effectively prevents debris from entering the braking mechanism 6, thereby reducing its braking effect.

[0040] See Figure 1 and Figure 2 As shown, a servo motor 4 capable of driving the take-up roller 3 to rotate is fixed on the side of the fixed frame 1 away from the braking mechanism 6. The output end of the servo motor 4 is fixedly connected to the end of the take-up roller 3.

[0041] When the servo motor 4 is started, it can drive the take-up roller 3 to rotate. When the take-up roller 3 rotates, it can take up or release the wire.

[0042] See Figure 1 and Figure 2 As shown, a controller 5 is fixed to the top of the mounting bracket 1. The controller 5 is electrically connected to the servo motor 4 and the braking mechanism 6 respectively.

[0043] By fixing the controller 5 to the top of the mounting bracket 1, and then electrically connecting the controller 5 to the servo motor 4 and the braking mechanism 6 respectively, the controller 5 can control the servo motor 4 and the braking mechanism 6 to work.

[0044] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
