Electric ring chain elevator

Abstract

The invention discloses an electric chain hoist, belonging to the technical field of hoisting device design, including an upper hook, an upper spring buckle, a sprocket box, a chain, a fixing seat, a lower hook, a lower spring buckle, a controller, Control box, the upper hook is fixed on the top of the sprocket box, the whole device can be suspended on the workshop truss by the upper hook, the sprocket is installed inside the sprocket box, the sprocket shaft is supported on the box of the sprocket box, the chain is in The inner cavity of the sprocket box bypasses the sprocket, and the bottom of the chain is fixed with a lower hook. When lifting heavy objects, the lower hook will hook the heavy objects, and the heavy objects can be lifted to the desired position by pulling the chain. The sprocket box A control box is fixed at the front of the invention. The electric chain hoist disclosed by the present invention has the advantages of convenient operation, low cost and good safety. Strong, long service life, rapid braking, accurate positioning.

Description

technical field [0001] The invention relates to the technical field of hoisting device design, in particular to an electric chain hoist. Background technique [0002] In the mechanical industry and daily life, we often need to carry out heavy objects in a certain range. In some cases, because the weight of the heavy objects is too large, the traditional manual method will cause the labor intensity of the workers and the handling efficiency is low. Previously Due to defects in the structural design of the heavy object lifting device used, there is no special braking device, which leads to the need to manually pull the chain to prevent the sprocket from reversing during the transportation of the heavy object. The labor intensity of the workers is high, the operation is troublesome, and the efficiency Low, and sometimes it may even drop suddenly during the transportation of heavy objects, causing major safety problems. Therefore, a design is designed that is easy to operate, lo...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects of heavy labor intensity, cumbersome operation, low efficiency and poor safety of workers in the previous heavy object lifting device, and design an electric chain hoist, which is easy to operate, low in cost, good in safety, and easy to lift. The hook has high strength, strong bearing capacity, rapid braking and accurate positioning
