[0043] In the use process of the large display screen, the personnel places the large display screen in the limiting frame 90601, and then controls the eight groups of third electric push rods 90603 to drive the four groups of limiting blocks 90605 to clamp the four corners of the display screen, so that the four corners of the display screen abut against a corresponding group of rubber protective pads 90607, and then controls the two groups of adjusting blocks 90609 to drive the four groups of translation plates 90610 to move towards the center of the limiting frame 90601, and then inflates the two groups of folding air bags 90611 through the corresponding inflation tools, so that the display product can be protected by the shock absorption of the four groups of limiting blocks 90605 and the protection of the air bag plate 90608 and the two groups of folding air bags 90611, thereby avoiding the vibration and collision problems in the transportation process, and improving the transportation safety of the transportation device.

[0044] For example, Figure 9As shown, the first moving assembly 908 comprises a second damper 90801; the second damper 90801 is in transmission connection with a corresponding group of second electric push rods 907; the other end of the second damper 90801 is connected with a second motor 90802; the output end of the second motor 90802 is in transmission connection with a guide column 90803; a plurality of groups of second guide teeth 90804 are arranged in an annular array on the outer wall of the guide column 90803; each group of second guide teeth 90804 is provided with a group of rolling columns 90805 away from one end of the guide column 90803; a universal ball 90806 is arranged on the side wall of the guide column 90803 away from the second motor 90802.

[0045] In the use process of the large display screen, the second motor 90802 is connected with the corresponding second electric push rod 907 by setting the second damper 90801, so that when the circulating storage mechanism 9 fails, the corresponding second electric push rod 907 can drive the corresponding first moving assembly 908 and second moving assembly 909 to separate from the two groups of guide grooves 902, thereby completing the disassembly work of the guide frame 905 and the limiting assembly 906, and by setting a group of rolling columns 90805 away from one end of each group of second guide teeth 90804 and a universal ball 90806 on the side wall of the guide column 90803 away from the second motor 90802, the moving resistance of the guide frame 905 can be reduced, thereby improving the maintenance efficiency of the transportation device while reducing the operating power consumption.

[0046] By controlling the transportation box body 1 to be lifted to a corresponding height, then controlling the corresponding first moving assembly 908 to drive the guide frame 905 to move in the guide groove 902, and then controlling the guide frame 905 to stop moving after moving to a corresponding position, at this time, the personnel places the large display screen in the corresponding limiting assembly 906 for limiting and fixing, then controls this group of guide frames 905 to continue to move, because the two groups of guide grooves 902 are runway-shaped, the guide frame 905 can slowly return to the initial position, thereby realizing the circulating storage work, avoiding the need for personnel to move the display screen greatly in the existing transportation device, thereby improving the transportation efficiency and the use effect of the transportation device.

[0047] The personnel places the large display screen inside the limiting frame 90601, then controls the eight third electric push rods 90603 to drive the four limiting blocks 90605 to clamp the four corners of the display screen, so that the four corners of the display screen respectively abut against the corresponding group of rubber pads 90607, then controls the two adjusting blocks 90609 to drive the four translation plates 90610 to move towards the center of the limiting frame 90601, then inflates the two folding air bags 90611 through the corresponding inflation tools, so that the display product can avoid vibration and collision problems during transportation under the shock absorption of the four limiting blocks 90605 and the protection of the air bag plate 90608 and the two folding air bags 90611, thereby improving the transportation safety of the transportation device.

[0048] The second motor 90802 is connected with the corresponding second electric push rod 907 through the second shock absorber 90801, so that when the circulating storage mechanism 9 fails, the corresponding first moving assembly 908 and the second moving assembly 909 can be driven away from the two guide grooves 902 by controlling the corresponding second electric push rod 907, thereby completing the disassembly work of the guide frame 905 and the limiting assembly 906, and the moving resistance of the guide frame 905 can be reduced by arranging a group of rolling columns 90805 at one end of each second guide tooth 90804 away from the guide column 90803, and arranging a universal ball 90806 on the side wall of the guide column 90803 away from the second motor 90802, thereby improving the maintenance efficiency of the transportation device while reducing the operating power consumption.
