Telescopic lever hoisting equipment

Abstract

The invention discloses telescopic lever hoisting equipment. The telescopic lever hoisting equipment adopts three-stage telescopic jib structure, wherein the telescopic sleeve on the outermost side isconnected with a hoisting column through a hinge pin, which is the sole fixed part in the jib system; the telescopic jib on the inner side is driven by a second hydraulic cylinder, the telescopic jibon the outer side is driven by a third hydraulic cylinder, a first hydraulic cylinder is connected with the telescopic sleeve on the outermost side through the hinge pin, and the inclination angle ofa telescopic lever structure is adjusted under driving of the first hydraulic cylinder, so that goods are ascended and descended. The telescopic lever hoisting equipment can be applied to almost allhoisting occasions, can be fixed on a certain work plane to serve as fixed hoisting equipment or can be used as movable hoisting equipment supported by certain movable equipment. The problem that large hoisting equipment cannot be carried and the goods are needed to be carried manually due to environmental space and other factors in the prior art are solved.

Description

technical field [0001] The invention relates to a lifting device, in particular to a retractable lever lifting device. Background technique [0002] Lifting equipment is electromechanical equipment used to carry or move heavy objects, mainly including lifting mechanism, operating mechanism, luffing mechanism, slewing mechanism and metal structure. The hoisting mechanism is the basic working mechanism of the crane. Most of them are composed of a suspension system and a winch. There are also hydraulic systems that lift heavy objects. Most of the suspension systems are suspended by wire ropes or slings. The operating mechanism is used to move heavy objects vertically and horizontally or adjust the working position of the crane, and is generally composed of a motor, a reducer, a brake and wheels. [0003] Existing lifting equipment usually has a huge structure and complex mechanism. For some very special workplaces, the environment is harsh and the working space is limited. Wor...

AI Technical Summary

Problems solved by technology

[0003] Existing lifting equipment usually has a huge structure and complex mechanism. For some very special workplaces, the environment is harsh and the working space is limited. Working in this environment, it is impossible to use large lifting equipment to carry or move goods, and only rely on workers To carry or move, the traditional way of carrying is that the workers carry it by hand and use small lifting equipment such as chain hoists. The labor intensity is huge, the production efficiency is very low, and the production cost of the enterprise is also increased.
