Fig. 14 is a schematic view showing a state where the lower opening type lifting door c22 of the lifting device is opened and then is flush with the position of the upper partition c12, and is used for lowering and throwing the delivery vehicle c3 loaded on the upper partition c12 or recovering the delivery vehicle c3 onto the upper partition c12, and the upper opening door c21 is opened.

The delivery control system of the transfer trolley can freely lift and open and close the lifting platform of the lifting device, namely the lower open type lifting door c22 between the upper layer clapboard c12, the bottom plate c11 and the ground according to the delivery and recovery requirements. Obviously, the lifting device and the lifting method of the present embodiment can completely add a layer of layered partition as a middle layer partition or an upper layer partition in the car c1, and extend from two layers to three or more loading layer spaces.

The lifting platform of the lifting device, namely the lower opening type lifting door c22, is designed to be suitable for the requirement of the fully fixed partition board adopted in the embodiment, and because the upper partition board c12 is the fully fixed partition board, the sliding edges of the two side frame upright posts can slide up and down in the lifting chute c25 in a larger range by changing the heights of the left and right side frame upright posts of the lifting support, so that the lower opening type lifting door c22 can lift in a larger range and can stay at the position where the bottom plate c11 is flush with the upper partition board c12, and the lifting, throwing and recovering functions of the distribution vehicle c3 by the multi-layer distribution transfer vehicle c0 in the multi-layer loading space can be realized.
