Furthermore, a plurality of bearing cushion blocks and a plurality of connector connecting plates are arranged on the tool supporting plate.

Further, the dragging piece comprises a shaft and a horizontal bracket connected with the shaft, and the shaft is arranged at two end parts of the sliding beam assembly.

Furthermore, the shape of the middle connecting fork is in a herringbone shape.

Compared with the prior art, the beneficial effects of the utility model are that: demolish the in-process at platform, the utility model discloses a driving trolley can realize shifting the function of transporting, can also dismantle the component on the dismouting platform through the integrated instrument of instrument layer board, has practiced thrift the time and the cost of labor of dismouting, and whole driving trolley structural design is ingenious, utilizes the driving trolley major structure that side beam and intermediate junction fork formed, and the structure is firm, ensures the stability of operation.
