The transverse moving driving mechanism 3 comprises a fixed seat 31, a guide assembly 32 and a transverse moving driving piece; the fixed seat 31 is fixedly connected to the lifting platform 1, and is provided with a guide component 32; the guide assembly 32 is connected to the flap assembly 2 and is movable in the vehicle-cabin width direction by a traverse driving member.
When the lifting platform 1 is lifted to the same height as a wagon carriage, the transverse moving driving mechanism 3 drives the flap plate assembly 2 to move to be aligned with the interior of the wagon carriage along the width direction of the wagon carriage (so as to compensate the deviation stopping amount of the wagon carriage); then the overturning driving mechanism 4 drives the main turning plate 21 and the auxiliary turning plate 22 to synchronously rotate and abut against the inside of the carriage. In order to adapt trucks of different car widths, a main flap 21 and a sub flap 22 arranged in the car width direction are provided in the flap assembly 2, and the dimension of the main flap 21 in the car width direction can be set to be adapted to the car dimension of a small width, and the sum of the dimensions of the main flap 21 and the sub flap 22 in the car width direction can be set to be adapted to the car dimension of a large width. When loading and unloading the carriage with large width, the main turning plate 21 and the auxiliary turning plate 22 can be turned over together to be abutted to the carriage, when loading and unloading the carriage with small width, the main turning plate 21 is moved to be aligned to the inside of the carriage when the transverse moving driving mechanism 3 drives the turning plate assembly 2, then under the action of the turning driving mechanism 4, the main turning plate 21 and the auxiliary turning plate 22 are synchronously turned over to the carriage direction until the auxiliary turning plate 22 is abutted to the carriage door plate, at the moment, the auxiliary turning plate 22 is separated from the main turning plate 21 due to the stop of the carriage door plate, and the main turning plate 21 is continuously turned over to be abutted to the carriage under the action of the turning driving mechanism 4.
