The two ends of the lifting drive 33 are respectively connected to the support frame 1 and the wheel support 32; specifically, an L-shaped support 34 is fixedly arranged at the edge of the support frame 1, and the lifting drive 33 is a lifting cylinder, the cylinder barrel of the lifting cylinder is fixedly arranged on the L-shaped support 34, and the piston rod of the lifting cylinder passes through the support frame 1 and is hingedly connected to the wheel support 32, so that the lifting drive 33 drives the wheel support 32 to drive the roller 31 to rise and fall vertically relative to the support frame 1, and ensures that the wheel support 32 can drive the roller 31 to rotate automatically around the piston rod of the lifting cylinder. The wheel spacing detection member is used to detect the current height of the roller 31, and can specifically be a height detection sensor. The wheel spacing detection member and the lifting drive 33 are both connected to the controller.

[0049] When the wheelbase detection component detects that the current height of the roller 31 exceeds the set height, the wheelbase detection component sends a signal to the controller, and the controller sends a signal to the lifting drive component 33 after judgment and processing, controlling the lifting drive component 33 to automatically extend downward, and the lifting drive component 33 drives the roller 31 to automatically descend, so as to automatically adjust the height of the roller 31 of the lifting wheel group 3, ensuring that the roller 31 of each lifting wheel group 3 is always in contact with the ground, providing stable support for the whole set of equipment.
