10. A method of transporting a combined elevating, loading and unloading truck as claimed in any one of claims 1, 2, 3, 5, 6, 8 and 9, comprising the steps of:

s1: the frame (1) and the transition frame (2) are butted and then are drawn to an output port of a conveyor, and the transition plate (23) at the topmost layer is adjusted to be horizontally aligned with the conveyor;

s2: the conveyer feeds materials to a transition plate (23) on the topmost layer of the transition frame (2), after a group of storage boxes (3) are input, an electric hoist (25) is started and lifts the transition plate (23) to lift one layer, a layer of steel wire rope (24) is tightened to pull the transition plate (23) on the next layer to be horizontally aligned with the conveyer, and after the storage boxes (3) conveyed by the conveyer are received on the transition plate (23) on the bottommost layer, pushing parts on each group of transition plates (23) synchronously and linearly push the storage boxes (3) to be fed into corresponding layers of the bearing frame (14);

s3: starting the bearing rotary table (11) to rotate by 90 degrees, screwing the first group of bearing frames (14) which are subjected to loading out of the storage inlet (13), screwing the second group of empty bearing frames (14) into the storage inlet (13), simultaneously rotating the electric block (25) in the reverse direction, descending and overlapping the transition plates (23), recovering to the original position, conveying materials to the transition plate (23) at the topmost layer by the conveyor again, and repeating the S2 action to complete the loading of the second group of bearing frames (14);

s4: the bearing rotary table (11) is started again to rotate for 90 degrees, the second group of bearing frames (14) which are subjected to loading are screwed out of the storage inlet (13), the third group of empty bearing frames (14) are screwed into the storage inlet (13), meanwhile, the electric hoist (25) rotates reversely, the transition plates (23) descend and are overlapped, the original positions are recovered, the conveyor conveys materials to the transition plate (23) at the topmost layer again, and the action of S2 is repeated to complete the loading of the third group of bearing frames (14);

s5: the bearing rotary table (11) is started again to rotate 90 degrees, the third group of bearing frames (14) which are subjected to loading are screwed out of the storage inlet (13), and after the fourth group of empty bearing frames (14) are screwed into the storage inlet (13), loading of one group of carrying vehicles is stopped or the step S6 is continued;

s6: and continuously starting the electric hoist (25) to reversely rotate, descending and overlapping the transition plates (23), recovering to the original position, conveying the materials onto the transition plate (23) at the topmost layer by the conveyor again, repeating the S2 action to finish the feeding of the fourth group of bearing frames (14), and arranging a hinged door which is hinged on the side box shell (12) at the storage entrance (13) for closing the storage entrance (13).
