Abstract

The invention discloses a lifting chain lifting device for a crane. The lifting chain lifting device for the crane comprises a base and a crane main beam, a lifting chain winding mechanism and an electric rotating body are correspondingly arranged on the left side and the right side of the upper end of the base, the lower end of the crane main beam is correspondingly arranged on the electric rotating body, a limiting rail is laid at the upper end of the crane main beam, emergency clamping mechanisms are sequentially fixed on the limiting rail, each emergency clamping mechanism internally comprises a first clamping plate and a second clamping plate, hydraulic cylinders are arranged on the outer walls of the second clamping plates, and the hydraulic cylinders are arranged on the limiting rail through vertical plates. According to the lifting chain lifting device for the crane, the lifting chain winding mechanism, the electric rotating body, a PLC, the limiting rail, the emergency clamping mechanisms, a lifting wheel, a rotating bearing and a rotating speed sensor are arranged, so that the problem that during actual use of a crane lifting chain, the chain is prone to falling off, so that potential safety hazards are generated, and the lifting chain is prone to being worn are solved.

Description

technical field [0001] The invention relates to the technical field of crane equipment, in particular to a hoisting chain lifting device for a crane. Background technique [0002] A crane refers to a multi-action hoisting machine that can lift vertically and move heavy objects horizontally within a certain range. Also known as crane, aerial crane, crane. Now for the lifting equipment for lifting concrete pipes, the design of the sling is equipped with a chain hook. When the sling is used, it is directly responsible for the lifting and transportation of the goods. Its safety level is very high, and the crane needs to use the sling. The lifting device, the device at the present stage can meet its basic use requirements when in use, but there are still some deficiencies in actual use. [0003] After searching, the patent notification number is CN202729602U, which discloses a chain hoisting device for cranes. The purpose of the invention is to design a chain hoisting device fo...
