[0006] Preferably, two supporting tables are fixed on the lower side of the supporting plate on the outer frame, and the supporting plate and the supporting table are in sliding contact.

[0007] Preferably, a through slot is arranged on the outer frame for the supporting plate to pass through.

[0008] Preferably, the outer frame and the supporting plate are both made of stainless steel.

[0009] Preferably, a mobile power supply is fixedly installed on the outer frame, and the driving motor is electrically connected with the mobile power supply through a wire.

[0010] Preferably, a plurality of rollers are fixed on the bottom of the outer frame.

[0011] The beneficial effects of this utility model are as follows: When using this subway car lifting device, the outer frame is moved to a suitable position outside the subway car. Then, a drive motor drives a gear to rotate, which in turn moves a rack, which in turn moves a support plate to the bottom of the subway car to provide support. This process is repeated for the other outer frame. Finally, two cranes work simultaneously, hooking their hooks onto steel cables. The cranes then lift the steel cables and outer frames, thus lifting the subway car. The cranes then place the subway car onto the subway tracks. The support plate is then removed from the bottom of the subway car, and the cranes remove the outer frame from the subway tracks. In summary, this utility model is convenient to operate and facilitates rapid support and lifting of subway cars. Attached Figure Description
