| description | The invention discloses a hydraulic propelling structure of a shield tunneling machine, and belongs to the related field of urban construction. The hydraulic propelling structure comprises a mounting plate and a fixing hole formed in the mounting plate, wherein a hydraulic propelling unit is fixedly mounted in the fixing hole and comprises an oil cylinder shell fixedly mounted in the fixing hole, first oil pipe joints are arranged at two ends of the oil cylinder shell, a piston plate is arranged in the oil cylinder shell, a push rod penetrating one end of the oil cylinder shell is fixedly mounted on the piston plate, and a fixing component is arranged on the push rod. A mounting seat in the fixing component contacts with supporting pipe pieces and compresses two adjacent supporting pipe pieces, the mounting seat pulls a clamping rod to rotate through a connecting rod, and the clamping rod pushes the supporting pipe pieces towards a tunnel wall, so that the supporting pipe pieces are closely fitted with the tu |
