At this time, the output end of the third motor 6 drives the two synchronous wheels 62 and the synchronous belt 63 to move, thereby driving the hollow tire 64 to rotate. At this time, the hollow tire 64 is in contact with the ground and drives the whole to move through the universal wheel 11. When it moves to the specified position, the second stranding wheel 31 is driven to rotate through the output of the second motor 3. At this time, the second stranding wheel 31 will turn the second steel cable 32 Relax, then the truss 4 will expand outward, thereby increasing the moving distance of the truss 4, and then start the output end of the first motor 2 to drive the first twisting wheel 21 to rotate, and at this time the first steel cable 22 can drive the hook 23 to relax, so that the hook 23 moves downward, and the staff can place items on the hook 23, and then control the lifting structure to drive the items up again, and after the driving structure drives the equipment to the corresponding position, the lifting structure can drive the items down again to facilitate the user to pick up the items, and then the stm32 development board 56 will re-control the driving structure to drive the equipment back to its original position.
