Horizontal folding suspension arm

Abstract

The invention relates to hoisting equipment applicable to plants of automobiles, ships, etc., and in particular relates to a horizontal folding suspension arm, which comprises a joint block, wherein a main arm is hinged and connected at one end of the bottom surface of the joint block and a front arm is hinged and connected at the other end; the other end of the main arm is hinged and connected to a base; a first hydraulic cylinder is fixed on the base; the end of a first hydraulic cylinder rod of the first hydraulic cylinder is connected to a connecting lug base on the main arm; and a second hydraulic cylinder is arranged in the middle of the bottom surface of the joint block; and the end of a second hydraulic cylinder rod of the second hydraulic cylinder is connected to a connecting lug base on the front arm. The product disclosed by the invention is simple in structure and reasonable in design, and an extension length of the suspension arm can be determined as required, which not only meets a demand of the suspension arm on super length but also facilitates folding, so that transportation and storage spaces are greatly reduced, and hoisting efficiency and safety are improved.

Description

technical field [0001] The invention relates to a lifting device used in factories such as automobiles and ships, in particular to a horizontal folding boom. Background technique [0002] In military and civil technology, it is important to use the boom device to move heavy objects for loading and unloading from the truck crane. The traditional truck crane boom is relatively short, and it is difficult to accurately control the spatial position of the loaded and unloaded goods, which seriously affects the quality of the cargo. Loading efficiency and safety. At present, the folding of relevant domestic lifting arms requires a large space height, and there is no horizontally scalable lifting arm. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a simple, ingenious and reasonable horizontal folding boom. The boom can determine the extension length of the boom according to needs, and can be fol...
