Description

Technical Field

The winch can lift vertically, pull heavy objects horizontally or tilted. The winch is divided into two types: manual winch and electric winch. Electric winch is the main type now. It can be used alone or as a component of machinery such as lifting, road construction and mine hoisting. It is widely used due to its simple operation, large rope winding capacity and convenient relocation. It is mainly used for lifting or flat dragging of materials in construction, water conservancy projects, forestry, mining, docks, etc. However, there are still some problems when using existing lifting winches.

[0003] There is a winch with Chinese patent publication number CN209306861U, which includes a frame and a motor, a drum, a first brake, a reducer and a second brake arranged on the frame. The motor, the drum and the first brake are located on the same side of the reducer, and the second brake is located on the other side of the reducer; a first transmission shaft is provided between the motor and one end of the reducer, a first brake is provided on the first transmission shaft, a second transmission shaft is provided between the other end of the reducer and the drum, and a second brake is provided on the side of the second transmission shaft away from the drum; a wire rope is wound on the drum, a clearance zone for avoiding the wire rope is provided at the position of the frame corresponding to the drum, a slide plate for adjusting the size of the clearance zone is provided at the bottom of the frame, and the slide plate can slide horizontally along the frame; but when the winch is winding the wire rope, it is impossible to ensure that the wire rope can be wound sequentially, which may cause the wire rope to be unevenly wound outside the winding roller, thereby affecting the stability during lifting and lifting, and may cause the wire rope to slip.

[0004] Therefore, we propose a lifting winch with intelligent protection function to solve the above problems. Utility Model Content
