The thrust bearing is rolling friction and has a small friction coefficient, so the thrust bearing can be pushed to rotate by the electro-hydraulic push rod; before rotating, the end beam needs to be jacked up through the jacking oil cylinder, namely, the whole steering mechanism is lifted off the ground, and then rotating movement is carried out. Through the concertina movement of electricity liquid push rod, on transmitting the torsion seat with thrust, the torsion seat passes through the key and drives the primary shaft and rotate, and the secondary shaft in the primary shaft drive motor wheelset rotates again, has realized the rotary motion of wheel group promptly.

Compared with the prior art, the tire steering device for the self-moving type annular stacker has the advantages that the problem of difficult tire steering is solved through the electro-hydraulic push rod and the steering mechanism, the self-moving type annular stacker can be steered more flexibly, the purpose of working at various stations is achieved more easily, and the like, and the tire steering device is widely applied to the technical field of the self-moving type annular stacker.
