[0027] The third driving mechanism 7 includes a second gear 701 fixedly sleeved on the side wall of the second rotating shaft 602, and the side wall of the L-shaped plate 601 is fixedly connected to two symmetrically arranged third fixing blocks 703, and the side walls opposite to the two third fixing blocks 703 are fixedly connected to two symmetrically arranged second fixing rods 702, and the side walls of the second fixing rods 702 are sleeved with second racks 708, and the side walls of each second fixing rod 702 are sleeved with sixth springs 704, and the bottom of the second rack 708 is fixedly connected to an L-shaped block 705, and the top of the L-shaped block 705 is fixedly connected to the bottom of the second rack 708. The part is fixedly connected with a push plate 706, and the push plate 706 includes an inclined surface 707. When the moving block 506 continues to move, the fifth spring 508 is gradually compressed, and the moving block 506 is abutted against and slides against the inclined surface 707, thereby pushing the L-shaped block 705 to move away from the moving block 506. The movement of the L-shaped block 705 drives the movement of the second rack 708. At the same time, the sixth spring 704 is compressed.

When crossing the obstacle, the wheel 16 is put down again. This reciprocating process can be repeated. When encountering an obstacle, multiple groups of wheel assemblies can be lifted up in turn in the moving direction, and put down when crossing the obstacle, thereby realizing the straddle function, which is more convenient to use and has better effect.

[0029] Working principle: When in use, after the material is placed on the vehicle body 1, the moving assembly 505 is started, so that the moving block 506 moves in the direction close to the second connecting block 502. At this time, the first rack 503 is driven to move synchronously through the third T-shaped guide rod 507 and the fifth spring 508. At the same time, the fourth spring 504 is compressed. When the first rack 503 moves, it drives the first gear 501 and the worm 403 to rotate counterclockwise, and then drives the worm wheel 401 and the first rotating shaft 18 to rotate counterclockwise. When the first rotating shaft 18 rotates, it drives the rotating plate 19 and the supporting plate 20 to rotate, and then drives the rotating plate 21 to rotate, so that the moving plate 21 rotates to the top of the vehicle body 1. When the first rack 503 abuts against the side wall of the second connecting block 502, the first rack 503 no longer moves. At this time, the moving plate 21 is rotated to a horizontal position; When the moving block 506 continues to move, the fifth spring 508 is gradually compressed, and the moving block 506 is abutted against and slides against the inclined surface 707, thereby pushing the L-shaped block 705 to move in the direction away from the moving block 506. The movement of the L-shaped block 705 drives the movement of the second rack 708. At the same time, the sixth spring 704 is compressed. When the second rack 708 moves, it drives the second gear 701 and the second rotating shaft 602 to rotate clockwise, thereby driving the winding drum 603 to rotate. At this time, the pull rope 604 can be wound up, thereby pulling the slider 304 and the moving plate 21 downward, and driving the first T-shaped guide rod 22 to move downward through the telescopic mechanism 2. When the first T-shaped guide rod 22 abuts against the surface of the material, the first spring 202 is gradually compressed, and the first T-shaped guide rod 22 that does not abut against the surface of the material will abut against the top of the vehicle body 1, and can automatically adjust to the shape of the material, so that the material can be wrapped by the first T-shaped guide rod 22; Next, the electromagnet 1005 is powered off. After the electromagnet 1005 is powered off, the sliding plate 902 can move away from the first connecting block 1002 under the action of the second spring 1003, and at the same time, the plug plate 904 is driven to move, and the plug plate 904 is inserted into the annular groove 901 for limiting, so as to facilitate the limiting operation of the material, which is more stable and reliable, and can be automatically adjusted according to the shape of the material, with stronger applicability and more convenient use; During transportation, when encountering an obstacle, the cylinder 803 can be started to drive the moving frame 11 to move upward, thereby driving the wheel 16 to move upward through the rotating rod 12 and the U-shaped frame 14, and the wheel 16 is raised upward. When crossing the obstacle, the wheel 16 is put down again. This reciprocating process can be repeated. When encountering an obstacle, multiple groups of wheel assemblies can be raised upward in turn in the moving direction, and put down when crossing the obstacle, thereby realizing the straddle function, which is more convenient to use and has better effects.
