[0047] Working principle: After obtaining the slipping signal, the control drive motor 62 is started, and the drive motor 62 drives the threaded rod 63 to rotate, so that the second gear 64 and the third gear 65 rotate, driving the two boosting linkage devices 2 to rotate to both sides respectively; the first link 21 of the two boosting linkage devices 2 drives the second link 22 to rotate, and the second link 22 causes the first gear 23 to first engage with the rack 4 on one side of the support device 3; then the first link 21 continues to drive the second link 22 to rotate, and the first gear 23 moves along the rack 4 to both sides of the rack 4 until it engages with the internal gear 5 again, and then the rotation of the drive motor 62 stops; Then the control starts the wheel body 1, and after the wheel body 1 rotates clockwise, it drives the internal gear 5 to rotate. The rotation of the internal gear 5 drives the first gear 23 to rotate. Through the meshing relationship with the rack 4, the first gear 23 drives the support device 3 to extend obliquely downward; after the support device 3 extends, it acts on the land surface and at the same time pushes the wheel body 1 forward and upward in the reverse direction, so that the wheel body 1 gets out of the pit, as shown in Figure 5 shown; after the wheel body 1 gets out of the pit, the control stops the rotation of the wheel body 1, and at the same time starts the drive motor 62 to rotate in the reverse direction, so that the two boosting linkage devices 2 rotate towards the middle respectively, so that the first gear 23 disengages from both the rack 4 and the internal gear 5, and finally the support device 3 will also automatically reset.
