Device for facilitating loading and unloading of track type crane

Abstract

The invention provides a device for convenient loading and unloading of crawler cranes, which belongs to the technical field of crawler crane loading and unloading devices; the technical problem to be solved is to provide a device that can be freely loaded and unloaded on a carrier vehicle without relying on a large crane A crawler crane loading and unloading device; the technical solution adopted to solve this technical problem is: including the crane body and folding section outriggers, the number of the folding section outriggers is four, which are respectively arranged at the front and rear of the truck body Among the four corners of the folding section, the legs of the folding section are divided into upper and lower sections, and the upper section of the folding section of the legs is connected with the crane body through a hydraulic support. The legs of the folded section of the lower section are fixedly connected; the legs of the folded section of the lower section and the legs of the extension section are equidistantly provided with pin holes along the direction of the center line, and the extension ends of the legs of the folded section of the lower section pass through The pin shaft is fixedly connected with one end of the extension leg; the invention is installed and applied to crawler cranes.

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 i
