Magnetic levitation train rescue wheel device and magnetic levitation train

A maglev train rescue wheel device, comprising a mounting base, wheel carriers, and a hydraulic cylinder, wherein

• the mounting base comprises a horizontal mounting base and a vertical mounting base, with the vertical mounting base located below the horizontal mounting base and connected to the horizontal mounting base;
• the wheel carriers are disposed on both sides of the vertical mounting base respectively and rotatably mounted to the vertical mounting base via an eccentric rotary shaft, and each of the wheel carriers is provided with a wheel mounted at an outer side of the wheel carrier through a wheel axle;
• the hydraulic cylinder is arranged obliquely, with one end hinged to the horizontal mounting base and the other end hinged to driving arms of the wheel carriers, to drive the wheel carriers along with the wheels to rotate around the eccentric rotary shaft, to make the wheels be in a retracted state or a lowered state;
• and
• each of the both sides of the vertical mounting base is provided with a limiting block, and each of the wheel carriers is provided with a support portion for positioning, wherein in the retracted state of the wheels, the support portion of each of the wheel carriers is not in contact with the corresponding limiting block;
• and in the lowered state of the wheels, the support portion of each of the wheel carriers upwardly abuts against the corresponding limiting block.
