One embodiment of the present invention provides a torsion beam hinge apparatus applied to a shield tunneling machine, including: articulated elements 3 and locking piece, 2 articulated joints with anterior shield 1 that pass through of torque beam anterior segment 3 are articulated, and 2 torque beam anterior segments can rotate around articulated elements 3, and the pivoted angle can be adjusted as required, after rotating, carries out the locking with 2 torque beam anterior segments and anterior shield 1 through the locking piece to improve rigidity between them. The existing front shield 1 and the torque beam front section 2 are fixedly connected, an included angle between the axis of the front shield 1 and the axis of the tightening shield 8 is recorded as a, the front shield 1 and the torque beam front section 2 are arranged in a hinged connection mode, the torque beam front section 2 can rotate around the front shield 1 within a preset range, the maximum rotation angle is recorded as b, and the included angle between the axis of the front shield 1 and the axis of the tightening shield 8 is the sum of a and b, so that the minimum turning radius of the shield machine is reduced, and the adaptability of the shield machine is improved.

Specifically, the articulated elements 3 are articulated shafts which vertically penetrate through the front sections 2 and 1 of the torsion beams, for example, an articulated shaft which is detachably connected to the front shield 1 can be arranged, the front shield 1 and the front sections 2 of the torsion beams are provided with through holes, and after the through holes are aligned, the articulated shafts penetrate through the through holes to realize articulation.

In order to facilitate the connection between the front shield 1 and the front section 2 of the torsion beam, a connecting plate is arranged on one side of the front shield 1 facing the torsion beam, and a hinge 3 vertically penetrates through the connecting plate and the front section 2 of the torsion beam.
