Winch stall self-locking device capable of preventing winch from stalling and hurting people in use process

Abstract

The invention relates to the technical field of winches, and discloses a winch stall self-locking device for preventing a winch from stalling and hurting people in the use process. The winch stall self-locking device comprises a fixed disc, wherein a sliding groove is formed in the fixed disc; an electrorheological fluid is movably connected to the interior of the sliding groove; a spring I is fixedly connected to the bottom of the interior of the sliding groove; and a sliding block is fixedly connected to the side, away from the sliding groove, of the spring I. According to the winch stall self-locking device capable of preventing the winch from stalling and hurting people in the use process, when the winch stalls, the sliding block makes contact with a fixed block at the moment, the electrorheological fluid is changed into solid from liquid, and a rotating disc cannot rotate further, so that the effect of preventing the winch from stalling and hurting people in the hoisting process is achieved. Transverse rods are pulled upwards, then the sliding block is separated from the fixed block, the electrorheological fluid is further changed into liquid from solid, a limiting rod does not clamp a limiting block any more, and the rotating disc further restores to rotate, so that the effects of recycling and avoiding unnecessary waste are achieved.

Description

technical field [0001] The invention relates to the technical field of winches, in particular to a winch stall self-locking device for avoiding stalling and hurting people during the use of the winch. Background technique [0002] The winch, also known as the hoist, is a light and small lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects. It can be used alone or as a component in machinery such as lifting, road construction and mine lifting. , The winch has the advantages of large bearing capacity, stable and reliable hoisting, and a wide range of operating speeds. It is widely used, but due to the lack of awareness and effective methods for the safe use of winches, production accidents are often caused. [0003] During the use of the winch, due to the certain quality of the heavy objects it lifts, during the work process, due to mechanical failure or other reasons, stalling and falling may occur, which not only has great safety for the...
