Electric hoist device

Abstract

The invention discloses an electric hoist device which at least comprises a drum assembly, a speed reducer, a three-in-one driving system, fixing parts, a rack, a lifting height limiter, a limit switch fixing seat, screws, a gasket and a lifting hook assembly, wherein the drum assembly is arranged at one end of the rack and is connected with the speed reducer; the speed reducer is connected with the three-in-one driving system; the fixing parts are respectively arranged on the left side and the right side of the rack; the lifting height limiter is arranged at the front end of the limit switch fixing seat; the limit switch fixing seat is fixed on one side of the rack through the screws and the gasket; the lifting hook assembly is connected with the drum assembly through a bearing, a pulley and a steel wire rope. According to the electric hoist device, on the premise that lifting functions can be met, a limiter is supposed to be arranged on the original electric hoist device, so the limitation of the position is more accurate. The electric hoist device has the advantages of simple integral structure, high practicality, and high convenience for popularization and use.

Description

technical field [0001] The invention relates to a hoisting device, in particular to an electric hoist device. Background technique [0002] Electric hoist, referred to as electric hoist, is a light and small lifting equipment. Most electric hoists are operated by people on the ground using buttons, or they can also be operated in the cab or controlled by wired (wireless) remote control. Electric hoist is a kind of special lifting equipment, which is installed on the crane and gantry crane. It has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, storage terminals and other places. The lifting capacity is generally 0.1-80 tons, and the lifting height is 3-30 meters. It consists of a motor, a transmission mechanism, a drum or a sprocket, and is divided into two types: wire rope electric hoist and chain electric hoist. Electric chain hoists are divided into two types: imported and domest...

AI Technical Summary

Problems solved by technology

Electric chain hoists are divided into two types: imported and domestic; wire rope electric hoists are divided into CD1 type (single-speed lifting) and MD1 type (two-speed lifting); miniature electric hoists, winches, and multi-function hoists; the existing technology can generally meet the requirements of production. Life needs, but it cannot meet people's needs in terms of limit and control. This utility is designed on this basis
