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

Abstract

The invention discloses a winch, which comprises a servo motor, a roller mechanism coaxially connected with the servo motor, a transmission mechanism, a connecting rod control mechanism and a guide mechanism; the guide mechanism includes a guide rail, a lead screw, and a follower nut adapted to the lead screw , and, the follower pulley assembly fixedly connected with the follower nut; the follower pulley assembly also includes a through hole adapted to the guide rail; the transmission mechanism includes a transmission shaft provided with a first bevel gear, a second bevel gear and a third bevel gear; The link control mechanism is respectively connected with the first clutch mechanism and the second clutch mechanism, and is used to transmit the power of the transmission shaft to the fifth bevel gear through the time-sharing interlocking of the first clutch mechanism and the second clutch mechanism. The invention can realize the reliable winding of the rope on the drum mechanism, avoid the disorderly winding of the rope, and further improve the load stability of the hoist during the working process and when changing directions.

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 will f...
