Electric winch for building

Abstract

The invention discloses an electric winch for building. The electric winch comprises a rack, a motor, a first fixing plate, a rotating roller, a first supporting plate, a rotating shaft, a pushing assembly, a first wheel disc, a transmission belt, a second wheel disc, a brush, a third supporting plate and a fourth spring. A first sliding groove is formed in the first fixing plate. Through the pushing assembly, a cable can be shifted on one side of the rotating roller back and forth when the cable is contracted, so that the cable is uniformly and orderly wound on the rotating roller, and the cable can be convenient to use next time. Through the brush between the second supporting plate and the third supporting plate, soil and dust on the cable can be cleared away, and the tidiness of the cable is kept so that the cable can be convenient to use next time. After a transmission belt of an existing winch is loosened, a rotating drum is rotated, and under the matching of a steel wire rope, the position of a motor is adjusted, the friction force between the transmission belt and a first turntable and a second turntable is increased, and the winch can be normally used.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to an electric winch for construction. Background technique [0002] Hoist, a light and small lifting device that uses a reel to wind a wire rope or chain to lift or pull heavy objects, also known as a winch. The hoist can lift the weight vertically, horizontally or obliquely. The cable is easy to locate for winding, resulting in uneven winding, which will lead to the possibility of off-line or wrong line, which is not conducive to the next use; the existing hoist does not clean the water and dust on the cable when it takes up the line. The device will cause the cable to be entangled with mud, which will cause damage to the cable and is not conducive to the next use; the existing hoist has reduced friction after the transmission belt is loose, and cannot be adjusted in time, so that the hoist cannot be used normally. .
