Abstract

The invention discloses a chain block, and belongs to the technical field of design of hoisting devices. The chain block comprises an upper hoisting hook, an upper spring buckle, a sprocket box, a hand-pulled chain, a fixing seat, a lower hoisting hook, a lower spring buckle and a hoisting chain, wherein the upper hoisting hook is fixed to the top of the sprocket box; the whole device can be hung on a workshop truss through the upper hoisting hook; two cavities are formed in the sprocket box and used for installing sprockets combined with the hand-pulled chain and the hoisting chain in a winding mode correspondingly; a sprocket shaft is supported on a box body of the sprocket box; and the lower hoisting hook is fixed to the bottom of the hoisting chain and used for hooking a weight when the weight is hoisted, and then the weight can be hoisted to the needed position by pulling the hand-pulled chain. The chain block disclosed by the invention is simple in structure, convenient to operate, low in cost, good in safety and good in hoisting reliability. The hoisting hooks are high in strength, high in bearing capacity and long in 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 ...
