Abstract
A drive device for a belt axis of a winch, to address the problems existing in the conventional drive device for the belt axis of the winch including a short service life and a high cost. The drive device is disposed at the end of the belt axis of the winch. The drive device comprises a stationary seat and a rotary cylinder. The rotary cylinder is provided with a socket for inserting a crowbar. The stationary seat is fixedly connected with the belt axis. The rotary cylinder is axially fixed to the stationary seat. A unidirectional mechanism is provided between the rotary cylinder and the belt axis and operates by means of the engagement of teeth of the ratchet wheel. The belt axis is brought into continuous one-way rotation by using the unidirectional mechanism while the rotary cylinder is turned back and forth.
