The invention provides a maintenance trolley. A rotary crawling ladder and a supporting and lifting device are arranged on the maintenance trolley, so that high-altitude lifting operation can be achieved, and furthermore, the problem that universal wheels at the bottom of the maintenance trolley cannot bear large-tonnage equipment weight during high-altitude lifting operation, so that the universal wheels are easily damaged, and the whole maintenance trolley is paralyzed and cannot be used is solved.The gravity of to-be-repaired equipment can be transferred by an automatic landing device, so that it is guaranteed that the maintenance trolley cannot collapse or deform due to excessive load. In addition, for the problem that when the maintenance trolley works at a high position, the gravity center of the maintenance trolley is too high due to the high working position, and the maintenance trolley is prone to toppling over in the using process, support legs are additionally arranged on a bottom plate, and the gravity center of the maintenance trolley is lowered, therefore, the maintenance trolley is more stable to use.

    本发明提供一种检修小车,通过在检修小车设置旋转爬梯和撑举装置,可实现高处举重作业,进一步,为了避免检修小车底部万向轮在高处进行举重作业时,无法承受大吨位的设备重量,从而容易造成万向轮的损害导致整个检修小车瘫痪无法使用,本申请的自动落脚装置可以将待修设备的重力转移,保证检修小车不会因为载重过大而坍塌变形。此外,在高处工作时,较高的工作位点会导致检修小车的重心过高,在使用过程中易发生倾倒,通过在底板处增设支撑腿,降低检修小车的重心,从而使检修小车的使用更为稳固。
