s1, firstly, moving the transfer trolley to a designated place, when the goods are stacked to a high height, controlling the forward rotation of the double-shaft motor (3) through the control box (41), the forward rotation of the double-shaft motor (3) drives the two first screw rods (4) to rotate, the two first screw rods (4) enable the two racks (9) to be away from each other along with the movement of the two sets of first nuts (5) through the matching of the sliding grooves and the sliding blocks (6) in the rotating process, then the racks (9) are meshed with the transmission gears (7) in the moving process, the rotation of the gears (7) drives the rotating shafts (8) and the discs (11) to rotate, the discs (11) enable the bottom plate (15) to move downwards under the combined action of the first pin shaft, the supporting rod (12), the second pin shaft, the first hinge block (13) and the telescopic rod (14) in the rotating process, then the bottom plate (15) is contacted with the ground, and after the bottom plate (15) is contacted with the ground, the convex plate (1) and the pulley (34) can be integrally lifted, the pulley (34) is separated from the ground, the heights of the convex plate (1) and the U-shaped plate (27) are adjusted, the pulley (34) is not contacted with the ground any more, and then a worker can load goods into the U-shaped plate (27);

s2, after the goods are loaded, the control box (41) controls the double-shaft motor (3) to rotate reversely, so that the convex plate (1) and the pulley (34) descend integrally, the pulley (34) is in contact with the ground, and then a worker can move the transfer trolley by using the hand push frame (20);

s3, when unloading is needed, firstly separating the U-shaped rod (39) from the L-shaped rod (37), then opening the box door (38), enabling the box door (38) to be overlapped with the upper surface of the lower cargo plate (33), then controlling the forward rotation of the forward and reverse motor (19) through the control box (41), enabling the two second screw rods (24) to rotate forward through the cooperation of the forward and reverse motor (19), the three chain wheels (16) and the chain (17), enabling the second nut plate (21), the connecting plate (40) and the second hinge seat (42) to move upwards in the rotation process of the two second screw rods (24), enabling the left end of the U-shaped plate (27) to be inclined and lifted through the combined action of the third pin shaft, the ejector rod (22), the fourth pin shaft, the first hinge seat (23), the second hinge block (29), the fifth pin shaft and the third hinge block (31) in the upward movement process of the second hinge seat (42), and further enabling the cargo in the U-shaped plate (27) to slide downwards in an inclined and downwards under the action of the conveying roller (26), then the goods slide down to the ground through the box door (28) and the lower goods plate (33), thereby automatically discharging the goods.
