Multi-combination winch with external disc brake

Abstract

The invention discloses a multi-combination winch with an external disc brake. The winch comprises an explosion-proof motor, a safety brake, a brake disc, the disc brake, a reel quick change device, and a disc brake component, wherein the explosion-proof motor is installed at the top of the winch, the top of the winch is provided with a working brake, the top of the winch is equipped with a reel device, the outside of the reel device is fixedly connected to the disc brake and the reel quick change device, and the disc brake component is arranged outside of the disc brake and the reel quick change device. The multi-combination winch with the external disc brake, by externally installing the disc brake, can increase the contact area between the disc brake and the brake disc and make the braking force more reliable. The disc brake is externally installed to reduce the width of the equipment and provide great convenience for the transportation and use of the equipment. In this way, the brake foundation can be set separately to reduce the outline size of the equipment foundation; and the brake foundation and the winch foundation are separated independently to reduce vibration and have strong practicability.

Description

technical field [0001] The invention relates to the technical field of winches, in particular to a winch with external disc brakes and multiple combinations. Background technique [0002] The winch is also called the hoist, which is a light and small lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects. The hoist can lift the weight vertically, horizontally or obliquely. The hoist is divided into manual hoist, electric hoist and hydraulic hoist. Three types, mainly used for lifting or flat dragging of materials in construction, water conservancy projects, forestry, mines, docks, etc. [0003] The safety braking of ordinary two-speed multi-purpose winches on the market is achieved by installing a hydraulic pusher on the second output shaft of the reducer. There is no way to achieve safety braking by gearing other gears after the second shaft of the reducer. , there are major safety hazards when transporting heavy objects, and the safety ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a multi-combination winch with external disc brakes, which solves the problem that the safety braking of ordinary two-speed multi-purpose winches on the market is installed on the second output shaft of the reducer. The hydraulic pusher is used to realize the braking function. There is no way to achieve safe braking by other gears after the second shaft of the reducer. There are major safety hazards when transporting heavy objects. The safety is not strong, and the application is more troublesome.
