[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 for lifting, road construction and mine hoisting.

[0032] As a technical optimization solution of the utility model, the winch winding wheel 2 can be fixed by setting a base. The user fixes the support plate 102 on both sides of the top of the base plate 101, and then fixes the connecting plate 103 on the top of the support plate 102, and supports the sliding sleeve 22 through the connecting plate 103.

[0034] As a technical optimization solution of the utility model, by setting a winch winding wheel 2, the chain of the winch can be wound up.

[0041] The working principle and use process of the utility model are as follows: when in use, the user first connects the connecting shaft 21 to the output end of the winch motor, and then winds the chain around the surface of the winding drum 23. After completion, the friction plate 44 is pushed backward by a tool, and the friction plate 44 drives the connecting block 43 to move backward, and the connecting block 43 drives the H-shaped moving plate 42 to make a circular motion backward with the positioner 41 as the center of the circle, and the H-shaped moving plate 42 drives the fixing rod 33 to move backward through the pulling block 34, and the fixing rod 33 drives the sliding plate 32 to move backward to compress the spring 35, and then drives the winch motor, and the winch motor drives the connecting shaft 21 rotates, the connecting shaft 21 drives the winding drum 23 to rotate, the chain is wound by the rotation of the winding drum 23, and then the friction plate 44 is loosened, the sliding plate 32 is reset by the spring 35, the sliding plate 32 drives the fixed rod 33 to move backward, the fixed rod 33 drives the H-shaped moving plate 42 to reset through the pulling block 34, the H-shaped moving plate 42 drives the friction plate 44 to reset through the connecting block 43, so that the friction plate 44 contacts with the chain, and when the winch fails to lower the hoisted object, the movement of the chain will generate greater friction with the friction plate 44, so that the friction plate 44 slows down the movement speed of the chain.

[0042] To sum up: the winch frame welding structure can pull the friction reduction mechanism 4 to move forward by setting a pulling mechanism 3, and the chain on the winch winding wheel 2 is frictionally decelerated by the friction reduction mechanism 4. When the winch fails to lower the hoisted object, the weight of the hoisted object will not accelerate the speed of the chain movement, which can slow down the falling speed of the fallen object and slow down the movement speed of the winch chain without causing major losses.
