Abstract

The invention discloses a differential windlass lifting device, and belongs to the field of lifting machinery. The differential windlass lifting device comprises a bearing base, a drum shaft, a fixedpulley module, a movable pulley module, a lifting rope and a speed reducer. The differential windlass lifting device is characterized by further comprising a differential drum set, a coupling and a motor; the differential drum set is fixed on the drum shaft, and is integrally molded by a first differential drum and a second differential drum; the diameter of the first differential drum is larger than the diameter of the second differential drum; one end of the lifting rope is fixed at the end part of the first differential drum, and the other end is fixed at the end part of the second differential drum; one end of the drum shaft is connected with the bearing base, and the other end is connected with the speed reducer; one end of the coupling is connected with the speed reducer, and the other end is connected with the motor; and a brake is mounted on the coupling. Through use of the differential drum set and a specific rope winding mode, the high-capacity and low-speed lifting of the lifting mechanism can be realized, and the lifting stability and safety are guaranteed.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a differential winch lifting device. Background technique [0002] A hoist is a light and small lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects, also known as a winch. 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 lifting, road building and mine hoisting machinery. It is widely used because of its simple operation, large amount of rope winding and convenient displacement. [0003] The traditional hoisting method generally adopts a double-connected single-drum structure, and the two hoisting ropes are wound onto the drum from the same radial side of the drum. When the driving device drives the reel to rotate, the two ropes are all wound into t...
