Abstract

The invention provides an omnibearing mobile electric jack, comprising a basis bearing platform, an electric jack assembly and an automatic suspension device, wherein the electric jack assembly is mounted on the basis bearing platform, the automatic suspension device comprises a moving wheel assembly and a hanging device, the moving wheel assembly is connected with the basis bearing platform, and the hanging device is connected with the moving wheel assembly. According to the omnibearing mobile electric jack, automatic switching between a moving state and an airplane jacking operating state can be realized through the automatic suspension device, so the moving is convenient; compared with a conventional hydraulic jack, the adopted electric jack assembly has the advantages of greatly improving movement control, the accuracy and fast degree, avoiding the defects of a hydraulic cylinder that the leakage possibility is great, adding a mechanical locking device is needed, the stability is poor, the accuracy is low, regular maintenance is needed, a function is limited, and the like, shortening the airplane jacking and supporting operation time, and improving the operation efficiency.

Description

technical field [0001] The invention relates to the field of jacks, in particular to an omnidirectional mobile electric jack. Background technique [0002] In the process of aircraft assembly and maintenance, a kind of jack is needed to support the aircraft, and usually three jacks are required to complete the support work. A jack is respectively placed on the positions of the left and right wings, and a jack is placed at the position of the nose or the tail of different models to support the aircraft through three jacking points, so that the aircraft wheels leave the ground. Due to the heavy weight and large volume of large aircraft, it is necessary for the jack to have a larger fixed stable surface and push-off capacity. But the existing aircraft jacking operation is very inconvenient, the operation time is long, and the efficiency is low. Contents of the invention [0003] The present invention provides an omnidirectional mobile electric jack, aiming to improve the ab...
