Light multifunctional crane with seven telescopic arms

Abstract

The invention discloses a light multifunctional crane with seven telescopic arms. The light multifunctional crane comprises a supporting seat, a fixed frame is assembled on the upper side of the outer side wall of the supporting sea in a hinged mode, a telescopic arm frame is fixedly installed on the inner side wall of the fixed frame, suspension arms are sequentially assembled on the inner side wall of the telescopic arm frame in an inserting mode, supporting frames are fixedly installed at the right ends of the suspension arms, and stretchable oil cylinders are fixedly mounted on the outer side walls of connecting blocks. According to the light multifunctional crane with the seven telescopic arms, the size of the designed supporting seat is small, the installation area of the crane is small, meanwhile, the seven telescopic arms are arranged, and therefore the retracting length of the crane is short, the working amplitude can reach 10 m, the working amplitude is large, and the speed of the suspension arms during stretching and retracting can be increased through the six sets of stretchable oil cylinders; and in addition, the stretchable oil cylinders are arranged on the outer side of the telescopic arm frame, so that the stability of the suspension arms is effectively guaranteed, fault judgment and maintenance are facilitated, and the light crane is small in occupied space, flexible, easy to operate, convenient to carry by a truck and an oversize vehicle and wide in application range.

Description

Technical field [0001] The present invention relates to the field of cranes, in particular a light versatile crane having a seven-stage telescopic arm. Background technique [0002] In the construction and other places, it is necessary to use a crane to carry out the horizontal handling of objects, and a light crane is needed at very time, but the existing light crane is not enough, the operating range is small, and the telescopic process is slow. And since the cylinder that controls the bumble arm retractable, it is difficult to determine the fault and repair, which makes the scope of application of light cranes. If it is designed to have a longer telescopic length, there is a faster The telescopic speed, and it is easy to repair the light crane of the telescopic cylinder to solve such problems. To this end, we propose a light versatile crane with a seven telescopic arm. Inventive content [0003] It is an object of the present invention to provide a lightweight multifunction c...

Problems solved by technology

[0002] In construction and other places, cranes are required to carry out horizontal transportation of objects, and light cranes are often used, but the existing light cranes have insufficient telescopic length, small operating range, and slow telescopic process. , and because the oil cylinders that control the expansion and contraction of the boom are mostly installed in the boom, it is difficult to judge the fault and repair it, so that the scope of application of the light crane is small. A light-duty crane with high telescopic speed and easy maintenance of the telescopic oil cylinder can solve such problems. For this reason, we propose a light-duty multifunctional crane with a seven-section telescopic boom
