More Information
Summary:The utility model provides a large-diameter double-*-shaped beam active hinge shield tunneling machine for small curve turning, which comprises a cutterhead, the cutterhead is connected with a main drive, the main drive is connected with a front middle shield, the front middle shield and the main drive are both connected with a first support mechanism, and the front middle shield and the first support mechanism are both movably connected with a second support mechanism. According to the utility model, the shield tunneling machine main machine is divided into two parts capable of moving relatively through the active hinge structure; therefore, the problem of small turning of the super-large-diameter active hinge shield tunneling machine is solved; by means of the structural design of the double *-shaped beams, the requirement for adjusting the overall posture of the shield tunneling machine is met between the independent *-shaped beams, the functions of main drive independent stretchingand independent swinging
