Abstract

The invention discloses a double-friction brake drum for a winch. The double-friction brake drum comprises a drum body and friction drums, wherein the friction drums are symmetrically arranged on twosides of the drum body, the drum body is provided with a plurality of steel cable grooves for limiting steel cables, and the inner sides of the friction drums are provided with outer rings for preventing the steel cables from slipping off. The structure is simple, the assembly is reasonable, and the braking efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of hoist brake drums, and in particular relates to a double-friction brake drum for a hoist. Background technique [0002] Hoist, also known as winch, is a light and small lifting device that uses a reel to wind a wire rope or chain to lift or pull heavy objects. The hoist can lift heavy objects vertically, horizontally or obliquely. The hoist is divided into three types: manual hoist, electric hoist and hydraulic hoist. Now mainly electric hoist. 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] However, the hoist is inseparable from the braking device, and the existing braking device adopts a mechanical clut...
