Description

Technical Field

[0001] The utility model relates to the technical field of winches, in particular to a bidirectional self-locking winch. Background Art

[0002] A winch is a small and light lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects. It is also called a winch. The winch can lift vertically, pull horizontally or tilt heavy objects. There are three types of winches: manual winches, electric winches and hydraulic winches. Electric winches are the main type. It can be used alone or as a component of machinery such as lifting, road construction and mine hoisting. It is widely used because of its simple operation, large rope winding capacity and convenient relocation. The two-way self-locking winch has a two-way self-locking function, that is, it can achieve self-locking in both directions to prevent the heavy object from accidentally sliding down or rising, thereby improving work safety.

[0003] When the existing two-way self-locking winch is in the locked state, the winch fixes the wire rope mainly relying on the friction of the self-locking mechanism. However, this friction may be affected by many factors, such as the material, surface condition, humidity, temperature, etc. of the wire rope, resulting in an unstable locking effect. In addition, the wire rope may move slightly due to external factors (such as wind, vibration, etc.), and this movement may destroy the friction balance of the self-locking mechanism, resulting in failure of the locked state.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4 The utility model provides a two-way self-locking winch, including a base 1, a winch body 2, an adjusting structure 6, a limit frame 3, two groups of cylinders 4 and two clamping seats 5. The winch body 2 is arranged on the top of the base 1, and an adjusting structure 6 is arranged on the front side of the base 1. The limit frame 3 is connected to the adjusting structure 6. Rope threading holes are opened on the front and rear sides of the limit frame 3. The steel wire rope of the winch body 2 movably passes through the rope threading holes of the limit frame 3. The two groups of cylinders 4 are respectively arranged on the left and right sides outside the limit frame 3, and the driving ends of the two groups of cylinders 4 are respectively movably passed through the left and right sides of the limit frame 3. The two clamping seats 5 are respectively arranged at the driving ends of the two groups of cylinders 4, and the two clamping seats 5 are symmetrically arranged on the left and right. The number of each group of cylinders 4 is two, and the two cylinders 4 are arranged one before and one after. When the winch body 2 is locked, the driving ends of the two groups of cylinders 4 will extend at the same time, thereby driving the two clamping seats 5 to move toward each other, thereby performing additional auxiliary fixation on the steel wire rope.

[0018] Specifically, the adjustment structure 6 includes a support box 61, a screw rod 62, a motor 63, a limit rod 64 and a movable seat 65. The support box 61 is arranged on the front side of the base 1, and an opening is opened at the top of the support box 61. The screw rod 62 is rotatably connected to the left and right sides of the support box 61 respectively. The motor 63 is arranged on the right side outside the support box 61, and the driving end of the motor 63 is connected to one end of the screw rod 62. The limit rod 64 is arranged between the left and right sides inside the support box 61, and the limit rod 64 is located below the screw rod 62. The movable seat 65 is movably connected to the screw rod 62 and the limit rod 64 respectively. The top of the movable seat 65 is connected to the outer bottom of the limit frame 3, and the limit frame 3 moves synchronously with the movable seat 65.

[0019] The adjustment structure 6 can make the wire ropes arranged in an orderly manner during the winding process. When winding, the staff turns on the motor 63, and the driving end of the motor 63 drives the screw rod 62 to rotate. Due to the limiting effect of the limit rod 64, the moving seat 65 can only drive the limit frame 3 to move horizontally in a straight line. When the limit frame 3 moves horizontally, the wire ropes can be arranged in an orderly manner on the drum of the winch body 2.

[0020] Specifically, two groups of support plates 7 are arranged at the top and bottom of the limit frame 3, and the two groups of support plates 7 are symmetrically arranged up and down, the number of each group of support plates 7 is two, and the two support plates 7 are arranged on the left and the right, and a cleaning box 8 is arranged between the two groups of support plates 7. Cleaning holes are opened on the front and back sides of the cleaning box 8, and a cleaning brush 9 is arranged in the cleaning hole. The steel wire rope of the winch body 2 moves through the cleaning hole of the cleaning box 8, and the cleaning brush 9 is in close contact with the steel wire rope of the winch body 2. The cleaning box 8 is located on the front side of the limit frame 3, and the cleaning box 8 moves synchronously with the limit frame 3. When the steel wire rope passes through the cleaning brush 9, the cleaning brush 9 will clean the surface of the steel wire rope.

[0021] Specifically, one side of the clamping seat 5 is an arc-shaped structure, and a fixing ball 10 is arranged on its surface. The fixing ball 10 increases the fixing strength between the clamping seat 5 and the steel wire rope in the winch body 2.

[0022] Specifically, the screw rod 62 is connected to the support box 61 via a bearing, the inner ring of the bearing is interference fit with the screw rod 62 , and the outer ring of the bearing is fixedly connected to the support box 61 .
