Problems solved by technology

Some existing chain hoists have a lifting sprocket, because of the one-way braking, only the lower hook can be used at one end, so that the lifting efficiency is not good, and more manpower is needed during the lifting process. The pressure plate is a spiral compression friction plate and there is a certain slippage before compression, which is easy to cause problems such as poor positioning progress

Abstract

The invention discloses a double-hook chain block. The double-hook chain block comprises a right shell, a driven disc, a brake disc, a chain wheel, a long shaft, support rods, a lifting chain wheel and a spline hole gear; the right shell is mounted on the side surface of a right wallboard, and the driven disc, the brake disc, the chain wheel, a spring, a locking nut and a gasket are arranged between the two; the driven disc and the brake disc are connected in a ratchet manner; a transmission tooth part engaged with a piece gear set is arranged at the left end of the long shaft; the right end of the long shaft is connected with the locking nut after vertically penetrating through the internals of the spline hole gear, a left wallboard, the lifting chain wheel, the right wallboard, the brakedisc, the driven disc and the gasket; multiple support rods are mounted between the left wallboard and the right wallboard; and a left shell is fixedly mounted on the side surface of the left wallboard, and the piece gear set and the spline hole gear in engaged connection are arranged between the two. The double-hook chain block has the advantages of two-way braking of a lifting chain, labor saving in weight lifting, good positioning precision, wide use angle range of double hooks and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of chain hoists, in particular to the technical field of double-hook chain hoists. 【Background technique】 [0002] Chain block is a kind of manual lifting machine that is easy to use and easy to carry. It uses an endless chain as a flexible lifting part. It can not only lift objects vertically, but also pull objects horizontally. It is suitable for factories, mines, and buildings It can be used to install machines and lift goods in construction sites, docks, warehouses and other places, especially in the open air and without power supply. It is often used for short-distance lifting of small equipment and goods. Some existing chain hoists have a lifting sprocket, because of the one-way braking, only the lower hook can be used at one end, so that the lifting efficiency is not good, and more manpower is needed during the lifting process. The pressure plate is a spiral compression friction plate and there is ...
