Referring to fig. 1, 2, 4, 8 and 9, the multifunctional loading, unloading and lifting equipment comprises a turnover structure arranged on a lifting platform 1, wherein the turnover structure comprises a turnover plate assembly 2 and a transverse movement driving mechanism 3, wherein the turnover plate assembly 2 comprises a main turnover plate 21 and an auxiliary turnover plate 22 arranged on at least one side of the main turnover plate 21 along the width direction of a carriage; the main turning plate 21 and the auxiliary turning plate 22 can be turned synchronously under the action of the turning driving mechanism 4, and the auxiliary turning plate 22 can be separated from the main turning plate 21 under the action of external force during turning. The transverse moving driving mechanism 3 comprises a fixed seat 31, a guide component 32 and a transverse moving driving piece; the fixed seat 31 is fixedly connected on the lifting platform 1, and a guide component 32 is arranged on the fixed seat; the guide assembly 32 is connected with the flap assembly 2 and can move along the width direction of the carriage under the action of the transverse driving piece.

When the lifting platform 1 is lifted to be equal to the height of a boxcar, firstly, the transverse moving driving mechanism 3 drives the turning plate component 2 to move to be aligned with the inner part of the boxcar along the width direction of the boxcar (so as to compensate the stopping offset of the boxcar); then the turnover 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 to trucks with different carriage widths, a main turning plate 21 and an auxiliary turning plate 22 which are arranged along the carriage width direction are arranged in the turning plate assembly 2, the size of the main turning plate 21 along the carriage width direction can be set to be matched with the carriage size with small width, and the sum of the sizes of the main turning plate 21 and the auxiliary turning plate 22 along the carriage width direction is set to be matched with the carriage size with large width. When loading and unloading goods to the carriage of major width, main board 21 and vice board 22 of turning over can overturn to the butt in the carriage together, and when loading and unloading goods to the carriage of minor width, when sideslip actuating mechanism 3 drive turns over board subassembly 2 and removes, it can to aim at the carriage inside with main board 21 of turning over moves, then under the effect of upset actuating mechanism 4, main board 21 and vice board 22 of turning over overturn to the carriage direction in step, until vice board 22 butt to the carriage door plant, at this moment, because of the backstop of carriage door plant, vice board 22 can separate with main board 21 of turning over, and main board 21 of turning over then can continue to overturn to the butt in the carriage under the effect of upset actuating mechanism 4. For example, when the auxiliary flaps 22 are disposed on both sides of the main flap 21, the main flap 21 and the two auxiliary flaps 22 can be matched to fit three car sizes with different widths.
