The invention discloses an intermediate jacking station rectifying device for a rectangular pipe jacking machine. The intermediate jacking station rectifying device for the rectangular pipe jacking machine comprises a rear casing which is arranged at a machine head of the pipe jacking machine. The intermediate jacking station rectifying device for the rectangular pipe jacking machine comprises a bearing ring which comprises a first base plate, a connecting ring and a plurality of oil cylinders; the first base plate extends towards one side to form into a first annular plate; the other side of the first base plate extends to form into a second annular plate; the second annular plate is connected with the rear casing of the machine head of the pipe jacking machine; the connecting ring comprises a second base plate; the second base plate extends towards the bearing ring direction to form into a third annular plate; the third annular plate and the first annular plate are mutually sleeved in a sliding mode; the oil cylinders are uniformly distributed inside the connecting ring along the tunneling ring surface and are respectively abutted against between the first base plate and the second base plate. During the long-distance tunnel construction, the intermediate jacking station rectifying device for the rectangular pipe jacking machine is simple in structure, strong in flexibility, can serve as a relay jacking device and achieve control to the tunneling direction and posture of the machine head of the pipe jacking machine.
Description
technical field [0001] The invention relates to a rectangular pipe jacking machine, in particular to a deviation correcting device for a relay room of the rectangular pipe jacking machine. Background technique [0002] The relay room device of the rectangular pipe jacking machine is usually suitable for the construction of long-distance excavation tunnels. The deviation correction function of the pipe machine head during the excavation process. The current rectifying device in the relay room generally adopts a hinged rectifying device. The hinged hydraulic cylinder adopts a double-acting form. The hydraulic cylinder seats at both ends are respectively connected with the front and rear shells. Relative sliding occurs between the shells until the required correction angle and posture are achieved. During the deviation correction process, due to the active retraction of the articulated hydraulic cylinder, the front shell of the pipe jacking machine has a relative retreat tren...
