The loading tray 3 is then pushed into the middle of the lifting tray 2 through the roller 36 at the bottom, so that the moving component is engaged into the guide groove 6. The lifting tray 2 is then driven up by the lifting drive device, thereby driving the loading tray 3 and the material to rise synchronously to realize the loading work. In addition, when the material on the loading tray 3 is used, the lifting drive device drives the lifting tray 2 and the loading tray 3 to descend to the lowest end. At this time, the roller 36 at the bottom of the loading tray 3 is in direct contact with the ground. By setting structures such as the support sleeve 32, the slider 33, and the spring 37, a buffering and shock absorbing effect can be played, thereby reducing the reaction force of the ground on the loading tray 3, thereby protecting the loading tray 3.

[0031] Two guide grooves 6 are symmetrically provided on the lifting tray 2, and the spacing between the two guide grooves 6 is adapted to the spacing between the moving components on both sides. The limiting component 4 is arranged at the front end middle position of the guide grooves 6 on both sides. The limiting component 4 includes an electric push rod 41, and the electric push rod 41 is provided with two, and the two electric push rods 41 are symmetrically fixedly installed in the installation groove 42 symmetrically provided in the middle of the front end of the lifting tray 2.

[0037] Working principle: during operation, the materials are stacked on the top of the support plate 31, and then the loading tray 3 is transferred as a whole to the side of the loading rack 1 by a forklift and placed on the ground. The telescopic end of the electric push rod 41 is controlled to be retracted, thereby driving the insert block 43 to be completely retracted into the installation slot 42, and then the loading tray 3 is introduced into the middle position of the lifting tray 2 through the guide slot 6. When the support sleeve 32 at the front end of the loading tray 3 contacts the innermost inner wall of the guide slot 6, the support sleeve 32 at the rear end of the loading tray 3 just completely passes through the limit assembly 4. At this time, the telescopic end of the electric push rod 41 is controlled to extend outward, thereby pushing the end of the insert block 43 into the slot 4 4, the entrance of the guide groove 6 is completely closed by the plug block 43, so that the loading tray 3 can be restricted on the lifting tray 2, and then the lifting tray 2 is driven to rise by the lifting drive device, thereby driving the loading tray 3 and the material to rise synchronously to realize the loading work. In addition, when the material on the loading tray 3 is used, the lifting drive device drives the lifting tray 2 and the loading tray 3 to descend to the lowest end. At this time, the bottom roller 36 of the loading tray 3 is in direct contact with the ground. By setting the support sleeve 32, the slider 33, the spring 37 and other structures, it can play a role of buffering and shock absorption, reduce the reaction force of the ground on the loading tray 3, and then protect the loading tray 3.
