Winch

Abstract

The invention discloses a winch. The winch comprises a servo motor, a roller mechanism coaxially connected with the servo motor, a transmission mechanism, a link control mechanism and a guide mechanism, wherein the guide mechanism comprises a guide rail, a lead screw, a follow-up nut adaptive to the lead screw, and a follow-up pulley assembly fixedly connected with the follow-up nut; the follow-uppulley assembly further comprises a through hole adaptive to the guide rail; and the transmission mechanism comprises a transmission shaft provided with a first bevel gear, a second bevel gear and athird bevel gear; and the link control mechanism is connected with a first clutch mechanism and a second clutch mechanism separately, and used for transferring power of the transmission shaft to a fifth bevel gear through the time-sharing interlocking of the first clutch mechanism and the second clutch mechanism. The winch is capable of realizing reliable winding for a rope on the roller mechanism, avoiding the disordered winding of the rope, and then improving the load stability of the winch in a working process and during turning.

Description

technical field [0001] The invention specifically relates to the field of engineering machinery, in particular to a winch. Background technique [0002] The hoist is a light and small lifting device that uses a reel mechanism to wind ropes of various materials to lift or pull heavy objects. The hoist can lift heavy objects vertically, horizontally or obliquely. Most of the current winches are mainly driven by electric power. It can be used alone or as a component in machinery such as lifting, road building and mine hoisting. It is widely used because of its simple operation, large amount of rope winding and convenient displacement. It is mainly used for material lifting or flat dragging in construction, water conservancy projects, forestry, mines, docks, etc. . [0003] The inventor has found through research that the hoisting machine in the prior art has at least the following defects: [0004] Due to the uncontrollability of the rope winding of the hoist, the rope wil...

AI Technical Summary

Problems solved by technology

[0004] Due to the uncontrollability of the rope winding of the hoist, the rope will form a certain angle with the guide pulley during the rotation of the drum mechanism, which makes it easy for the rope to form accumulation on the drum mechanism, thus making the load of the hoist to be retracted and unwound very large. Difficult to control
