Driving device for belt axle of winch

摘要

The present invention discloses a driving device for a belt axle of a winch, which addresses the problems existing in conventional winches, for example the driving devices being out of work attributing to wearing of the unidirectional teeth on the fixed base and rotary body of the winch. The rotary cylinder of the driving device of the invention is provided with insertion holes into which a crow bar can be inserted. The fixed base is fixedly connected with the belt axle of the winch. The rotary cylinder is covered on the fixed base and fixed thereto in the axial direction. A unidirectional mechanism is located between the rotary cylinder and the belt axle to be engaged by unidirectional teeth. As the shift element and shift plates can be conveniently removed, the worn shift plates or shift element can be conveniently replaced after being used for a long period.

主权项

1. A driving device positioned at an end of a belt axle (3) of a winch, comprising:
a base (1) fixedly connected to the belt axle (3), the belt axle (3) having an axial direction; a rotary cylinder (2) with insertion holes (2c) through which a crow bar is capable of being inserted, the rotary cylinder (2) is sleeved on the fixed base (1) and fixed thereto in the axial direction; a unidirectional mechanism disposed between the rotary cylinder (2) and the belt axle (3), the unidirectional mechanism having several ratchet teeth (3a) at the end of the belt axle (3); bar-shape slots (2a1) opened along the axial direction on sides of the rotary cylinder (2); at least one shift plate (10) is set in the bar-shape slots (2a1) and is capable of moving along the bar-shape slots (2a1), the shift plate (10) biased between the ratchet teeth (3a) by an elastic force of a spring (5); wherein the belt axle (3) rotates in one single direction by means of the unidirectional mechanism as the rotary cylinder (2) rotates in a forward direction.
