The double-layer movable rack 22 is used to allow the double-layer material rack 21 to move and rotate horizontally. Each layer of the double-layer material rack 21 is equipped with telescopic forks 4.

[0037] Specifically, one layer of the double-layer material rack 21 is raised to the same level as the shelf via a scissor lift 3. A material pallet containing workpieces to be processed is temporarily placed on this layer using a telescopic fork 4. Then, it is manually pushed to the workbench. The empty layer of the double-layer material rack 21 is raised to the same level as the workbench via a scissor lift 3. A material pallet containing processed workpieces is temporarily placed on this layer using a telescopic fork 4. Then, the material pallet containing workpieces to be processed on the other layer of the double-layer material rack 21 is placed on the workbench using a scissor lift 3 and a telescopic fork 4. This completes the automatic material pallet changing process. Alternatively, a second method can be used, where two pallets are forked at once from the shelf or workbench and placed on the upper and lower layers of the double-layer material rack 21 for temporary storage.

[0043] Specifically, when the turnover vehicle stops at the predetermined position of the rack, first, the deviation angle of the outer end surface of the double-layer material rack 21 and the corresponding end surface of the rack is adjusted through the detection data feedback of the left and right two sets of distance measuring sensors 214 arranged on the double-layer material rack 21, to ensure that the docking interface of the double-layer material rack 21 and the inlet and outlet of the rack storage location are in parallel state, then the distance measuring sensors of the telescopic distance measuring sensor assembly 213 are extended to detect the reference object, the position of the horizontal moving direction of the double-layer material rack 21 is adjusted through the feedback of the detection data, so that the docking interface of the double-layer material rack 21 is centered and aligned with the inlet and outlet of the rack storage location, and then the telescopic fork 4 forks or places the material tray.

[0044] It should be noted that the shear fork pushing cylinder 33, the base sliding mechanism 222 and the base rotating mechanism 223 are all provided with servo motors (not shown in the figure), and the control system carried on the trolley can control the servo motors according to the information fed back by the sensors to automatically adjust the position of the double-layer material rack 21 carrying the telescopic fork 4, so as to ensure the accuracy of the telescopic fork 4 when the telescopic fork 4 is extended to pick up or place the material pallet, and the telescopic fork 4 does not collide with the shelf.

[0045] Further, the telescopic fork 4 comprises an upper fork 41, a middle fork 42 and a bottom fork 43 from top to bottom, and the upper fork 41 is provided with a first hook 44, a second hook 45, a third hook 46 and a fourth hook 47 at the front end, the middle front end, the middle rear end and the rear end respectively.

[0047] After the operator controls the trolley to stop at the predetermined position through the driving mechanism at the rear of the vehicle body frame 1, the operator can automatically adjust the alignment of the double-layer material rack 21 and the telescopic fork 4 on the trolley with the shelf, and automatically complete the picking up or placing of the material pallet without manual operation, which is safe and efficient.

[0048] Working steps:

[0049] When the material pallet needs to be carried, the trolley is manually pushed to the predetermined position of the shelf, and then in the case that the first hook 44 at the end is connected with the shelf, the material pallet moves from the shelf to the double-layer material rack 21 of the trolley according to the following path:
