Description

Clutch mechanism of winch

Technical Field

The utility model belongs to the technical field of windlass, and particularly relates to a clutch mechanism of a windlass.

Background

The hoist, also called winch, is a light and small hoisting device which uses a winding drum to wind a steel wire rope or a chain to lift or pull a heavy object, and can vertically lift, horizontally or obliquely pull the heavy object, and most of the current hoists are electric hoists, can be used independently, can also be used as a component part in the machinery of lifting, road building, mine lifting and the like, and is widely applied due to simple operation, large rope winding quantity and convenient movement.

In general, the output shaft of the winch is always connected with the winding drum for transmission, and when an operator works by using the traditional winch, the winding drum rotates due to misoperation of the operator, which may cause safety accidents, because of relatively high labor intensity and low safety coefficient. Therefore, a clutch mechanism is required to be designed between the spool shaft and the spool, and when the spool works, the spool needs to be started through manual operation and mechanical control so as to improve the safety.
