Chain hoist

Abstract

The invention discloses a chain hoist, which belongs to the technical field of hoisting device design and includes an upper hook, a spring buckle, a sprocket box, a hand chain, a fixing seat, a lower hook, a card seat, a scroll spring, a round Holes, clips, and upper hooks are fixed on the top of the sprocket box. The whole device can be suspended on the workshop truss by the upper hook. The sprocket box is composed of two cavities. There are round holes processed, and the two cavities of the sprocket box are fixed through the round holes with connectors. The sprocket wheel winding the hand chain is installed in the sprocket box. The sprocket shaft is supported on the box body of the sprocket box. The bottom is fixed with a fixed seat, and the lower hook is installed on the fixed seat. The chain hoist disclosed by the present invention has the advantages of simple structure, convenient operation, low cost, good safety, good lifting stability, strong bearing capacity and long service life. .

Description

technical field [0001] The invention relates to the technical field of hoisting device design, in particular to a 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, the lifting efficiency is low, the required bracelet pull force is large, the labor intensity of the workers is high, the operation is troublesome, and sometimes even the heavy object suddenly falls during the transportation process, causing major safety hazards. Therefore, it is necessary to design a chain block with simple structure, convenient operation, low cost, good safety, good lifting stability, high hook strength, strong bearing capacity and ...

[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, the lifting efficiency is low, the required bracelet pull force is large, the labor intensity of the workers is high, the operation is troublesome, and sometimes even the heavy object suddenly falls during the transportation process, causing major safety hazards. Therefore, it is very necessary to design a chain hoist with simple structure, convenient operation, low cost, good safety, good lifting stability, high hook strength, strong bearing capacity and long service life.
