[0002] At present, the cutting cutterheads of the pipe jacking construction machines used in large-diameter tunnels are all made very large, and the torque generated when the cutterheads rotate and cut is also very large. The huge torque sometimes causes the overall deflection of the pipe jacking machinery and increases the construction difficulty. or make construction impossible

The invention provides a torque-balance jacking pipe, which comprises a cylindrical shell. A mud water cabin is separated from a working cabin by a cabin separating plate; a supporting arm is arranged at the center of a circular jacking pipe, the middle of an arm rod is fixedly arranged on the supporting arm, the two ends of the arm rod are respectively hinged with one end of an upper telescopic oil jack and one end of a lower telescopic oil jack, the other end of the upper telescopic oil jack is hinged on an upper tool arm through a shaft, and the other end of the lower telescopic oil jack is hinged on a lower tool arm through a shaft; the middle of an arm rod of the upper and lower tool arms is also fixedly arranged on the supporting arm, the two ends of the arm rod are respectively hinged with one end of a left telescopic oil jack and one end of a right telescopic oil jack, the other end of the left telescopic oil jack is hinged on a left tool arm through a shaft, and the other end of the right telescopic oil jack is hinged on a right tool arm through a shaft; and the inner ends of the left, right, front and back tool arms are respectively hinged on the supporting arm through pins, and drilling teeth are evenly distributed on the tool arms.
Description
1. Technical field [0001] The invention relates to a pipe jacking, in particular to a torque balanced pipe jacking of a pipe jacking construction machine. 2. Background technology: [0002] At present, the cutting cutterheads of the pipe jacking construction machines used in large-diameter tunnels are all made very large, and the torque generated when the cutterheads rotate and cut is also very large. The huge torque sometimes causes the overall deflection of the pipe jacking machinery and increases the construction difficulty. or make construction impossible. 3. Contents of the invention: [0003] The present invention makes up for the shortcomings of the above pipe jacking equipment, and provides a torque balanced pipe jacking. [0004] The present invention is achieved through the following technical solutions: [0005] A torque balance jacking pipe, including a cylindrical shell, a bulkhead separates the mud tank from the working cabin, a support arm is set at the ce...
