Abstract

The present invention relates to a pipe-jacking tunnelling machine, in particular to an active-type automatic deviation rectification device of the pipe-jacking tunnelling machine. The device can realize automatic, highly efficient, safe and reliable deviation rectification according to deviations of proceeding direction of the pipe-jacking tunnelling machine with respect to a pipeline designed axis. Deviation rectification output force of a hydraulic cylinder is weak; the active-type automatic deviation rectification device of the pipe-jacking tunnelling machine is capable of being used for curve pipe-jacking tunneling; technical basis for automation pipe-jacking tunnelling of the pipe-jacking tunnelling machine is provided; and problems of unsuccessful deviation rectification and low deviation rectification efficiency caused by misjudgments of operators or operating instruction input errors which are caused by influences of factors such as ever-changing construction conditions, extremely high labor intensity and insufficiency in operating experience or negligence of operation personnel are avoided; and therefore, pipe-jacking tunnelling efficiency is raised and quality of pipe-jacking construction is improved.

Description

technical field

[0001] The invention relates to a pipe jacking machine, in particular to an active automatic deviation correction device for a pipe jacking machine. Background technique

[0002] The environment of the working face of the pipe jacking machine is harsh and the geological conditions are complex. During the full-section cutting and jacking process of the pipe jacking machine, the force system acting on the machine is usually unbalanced. The imbalance of the force system makes the jacking The trajectory of the tunnel boring machine can never completely advance along the pipeline design axis, and it will deviate from the pipeline design axis at any time.

[0003] Axis deviation includes: the position offset of a certain point on the axis of the pipe jacking machine relative to the pipeline design axis, the pitch angle and horizontal azimuth of the pipe jacking machine axis relative to the pipeline design axis; therefore, the pipe jacking must be detected in real t...
