Background

The refining process of the mobile AOD stainless steel is characterized in that fixed AOD furnace body equipment is installed on a large-scale mobile frame, and the mobile frame moves between a smelting position and a position to be repaired. The AOD furnace moving trolley is provided with four groups of wheel travelling mechanisms, the wheel travelling mechanisms are vertically arranged on a moving frame through a hydraulic lifting cylinder, when smelting is carried out, the rod end of the hydraulic lifting cylinder 8 retracts upwards to lift the whole wheel travelling mechanism, wheels are separated from a track, the wheel travelling mechanisms are prevented from being damaged by vibration impact in the smelting process, when a furnace shell needs to be replaced, the wheel travelling mechanisms descend to the wheel surfaces to be in contact with the track, the moving frame continues to be lifted for a certain height, and then the moving frame travels to a position to be repaired. However, the wheel travelling mechanism side comprises a speed reducer and a driving mechanism, and the vertical center line of the installation part of the hydraulic lifting cylinder is at the center of the 2X2 wheel, so the gravity center of the wheel travelling mechanism is not overlapped on the vertical center line of the hydraulic lifting cylinder, and the gravity center is deviated to the driving side. In the lifting process, the wheel travelling mechanism can deflect under the action of gravity (see fig. 9), the four wheels are not on the same horizontal plane, and if the four wheels are not adjusted, the four wheels cannot simultaneously contact the horizontal rail when the wheel travelling mechanism descends, so that derailment or damage to the wheel travelling mechanism is caused.
