Stepping stabilizer and shield tunneling machine thereof

The utility model discloses a stepping stabilizer and a shield tunneling machine thereof, and solves the problems of vibration and rolling of a shield tunneling machine in the prior art. The stepping type stabilizer comprises a stepping seat, a stabilizer body capable of stretching out and drawing back relative to the stepping seat is arranged in the stepping seat in a sliding mode, and the stabilizer body moves along the stepping seat under the action of a stepping driving device. Wherein the stabilizer comprises a stabilizer oil cylinder, a supporting shoe is arranged at the telescopic end of the stabilizer oil cylinder, and the stabilizer oil cylinder is connected with the stepping driving device through a lug seat. The stepping driving device is adopted to drive the stabilizer to move relative to the stepping seat, so that the stabilizer and surrounding rock are relatively static, sliding friction between the stabilizer and the surrounding rock is effectively avoided, and abrasion energy consumption is re
