Description

Bidirectional self-locking structure based on winch Technical Field The utility model relates to the technical field of windlass, in particular to a bidirectional self-locking structure based on a windlass. Background The hoist is a small and light hoisting device, also called winch, for hoisting or pulling heavy objects by winding steel wire ropes or chains by using reels. The hoist may vertically lift, horizontally or obliquely drag the weight. The winch is divided into a manual winch, an electric winch and a hydraulic winch. The electric hoist is now the main. The self-locking structure can be used independently and can also be used as a component part in hoisting, road building, mine lifting and other machines, but the existing self-locking structure of the winch can still have some problems in the actual use process; The utility model discloses a locking protection architecture for hoist engine, including the hoist engine body, the winding drum lateral wall of hoist engine body is equipped with locking protection architecture, and locking protection architecture is connected with automatic unblock structure and manual unblock structure to the winding shaft locking protection of winding drum, has the characteristics that alleviate and cause the damage to the motor, and current hoist engine auto-lock structure is when using, often only can be singlely lock the operation in the decline in-process, can't lock the operation for the state of rising, leads to there is great limitation in the in-process of using, is unfavorable for the use.
