Problems solved by technology

It is used for short-distance hoisting of small equipment and goods. The existing hand chain hoists have defects in structural design. Falling will cause major safety problems, and there will also be a phenomenon that the lifting chain and the hand chain are stuck. Therefore, it is very important to design a hand chain block with simple structure, convenient operation, low cost, good safety and long service life.

Abstract

The invention discloses a chain hoist, which comprises a casing, a left wallboard, a right wallboard, a long shaft, an upper hook, a lower hook, a lifting device arranged in the casing, and a hand pull device for driving the lifting device to go up and down ; It is characterized in that: the hand chain hoist makes the hand chain wheel rotate through the hand chain, and then drives the lifting chain wheel to rotate through the interlocking parts to complete the lifting of the lower hook. The invention has the advantages of anti-jamming chain, anti-dropping and the like.

Description

technical field [0001] The invention belongs to the technical field of hoisting, in particular to a chain hoist. Background technique [0002] The chain hoist is also called the fairy gourd, which is a kind of manual lifting machine that is easy to use and easy to carry. It is also called "chain hoist" or "inverted chain". It is used for short-distance hoisting of small equipment and goods. The existing hand chain hoists have defects in structural design. Fall, cause major safety problem, also exist lifting chain and chain hoist stuck phenomenon, therefore design a kind of structure simple, easy to operate, cost is low, safety is good, the hand chain hoist with long service life is very important. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a chain hoist. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a chain hoist, including a cas...
