Device for facilitating loading and unloading of track type crane

Abstract

The invention discloses a device for facilitating loading and unloading of a track type crane and belongs to the technical field of track type crane loading and unloading devices. According to the track type crane loading and unloading device, free loading and unloading can be conducted on a carrying vehicle without the dependence of a large crane. The device comprises a crane vehicle body and four folding section supporting legs. The four folding section supporting legs are arranged in the four front and rear corners of the crane vehicle body correspondingly; each folding section supporting leg is divided into two upper and lower segments, and each upper-segment folding section supporting leg body is connected with the crane vehicle body through a hydraulic support; the device further comprises extending section supporting legs fixedly connected with the lower-segment folding section supporting leg bodies; pin shaft holes are formed in the supporting leg walls of the lower-segment folding section supporting leg bodies and the extending section supporting legs in the central line direction with equal distances; and the extending ends of the lower-segment folding section supportingleg bodies are fixedly connected with one ends of the extending section supporting legs through pin shafts. The device for facilitating loading and unloading of the track type crane is applied to thetrack type crane.

Description

technical field [0001] The invention discloses a device for facilitating the loading and unloading of crawler cranes, belonging to the technical field of crawler crane loading and unloading devices. Background technique [0002] Cranes, commonly known as cranes, are usually divided into truck cranes, crawler cranes and tire cranes. They are widely used in hoisting equipment, emergency rescue, lifting, machinery, rescue, etc.; The maintenance is usually carried out in the substation. Due to the complex and compact wiring, the limitation of adjacent interval positions, the adjacent live parts and the terrain restrictions such as cable trenches, large cranes cannot enter this environment to carry out work. [0003] In recent years, a small crawler crane has been applied in the power system. It adopts rubber crawler hydraulic traveling device, and the hoisting, telescopic, undulating and rotating devices are all driven by hydraulic pressure. It has the advantages of flexibility...

AI Technical Summary

Problems solved by technology

[0004] In actual work, the small crawler crane has the above advantages, but it also has some defects in use. As a crane, it needs a special large crane to load and unload it during the moving process. At the scene, a large crane is needed to hoist the small crawler crane onto the carrier vehicle, and then hoist it off after reaching the destination to start the work. After the work is completed, it will be hoisted back to the carrier vehicle, and then it will be hoisted back to the warehouse after being transported. The whole process is frequently carried out. Loading and unloading operations not only generate unnecessary hoisting costs, but also are slow and inefficient during the loading and unloading process. Therefore, it is necessary to improve the small crawler crane to realize that the small crawler crane can be carried without a special large crane. Loading and unloading operations on vehicles
