Chain hoist external power unit and chain hoist system

Abstract

The invention provides a chain block external power device and a chain block system. The chain block external power device comprises a main chain plate, four auxiliary chain plates, a support installed on the main chain plate, a motor installed on the main chain plate, and a controller used for controlling the rotation direction and the rotation speed of the motor. The support is in an X shape and comprises a first end, a second end, a third end and a fourth end, wherein the first end, the second end, the third end and the fourth end are arranged in the circumferential direction of the main chain plate and protrude to the outer side of the main chain plate; the first end, the second end, the third end and the fourth end are each provided with one auxiliary chain plate; an installation joint used for installing a chain block chain is formed between each of the four auxiliary chain plates and the main chain plate. By the adoption of the technical scheme, the chain block external power device and the chain block system are simple in structure, low in cost, durable, portable, wide in application range, high in hoisting weight, high in efficiency, safe, convenient to install and easy to maintain.

Description

Technical field [0001] The invention relates to the field of chain hoists, in particular to a chain hoist external power device and a chain hoist system. Background technique [0002] Chain hoist crane is a traditional manual lifting tool. It has the advantages of cheap, durable, portable, wide application range, and high lifting weight limit. However, it needs to be powered manually, and because it needs to be operated close, it is dangerous. Although electric hoists are widely used in the prior art, they are inconvenient to install, expensive, difficult to maintain, and not portable. Summary of the invention [0003] The invention provides a chain hoist external power device and chain hoist system with simple structure, low cost, durability, portability, wide application range, high lifting weight, high efficiency, safety, convenient installation and simple maintenance. [0004] In order to solve the above problems, as an aspect of the present invention, an external power device ...
