As shown in Figure 1, the steering structure of the shield machine of the present invention, including shield machine 1, set on 1 tail portion of shield machine
Steering structure and shield machine mole, shield machine inside the shield machine 1 spell loop device and hydraulic press；
The steering structure includes Telescopic support leg and control device, and the Telescopic support leg connects control device；
The Telescopic support leg includes hydraulic cylinder 2 and support device 3, and one end of the hydraulic cylinder 2 connects the support
Device 3, the other end of the hydraulic cylinder 2 connect the hydraulic press 4 inside shield machine 1；
The shield machine mole is set on the front end of shield machine 1, and the shield machine is spelled loop device and filled set on shield driving
The rear end put, the hydraulic press 4 are set on the rear end of shield machine 1；
The hydraulic press 4 connects the shield machine mole and the shield machine spells loop device.
The Telescopic support leg includes the first Telescopic support leg 5, the second Telescopic support leg 6, the scalable branch of third
7 and the 4th Telescopic support leg 8 of support leg, first Telescopic support leg 5, the second Telescopic support leg 6, the scalable branch of third
7 and the 4th Telescopic support leg 8 of support leg is respectively arranged on four, the upper and lower, left and right orientation of the shield machine 1.
First Telescopic support leg 5, the second Telescopic support leg 6, third Telescopic support leg 7 and the 4th are scalable
The length of the hydraulic cylinder 2 of supporting leg 8 is identical.
The Telescopic support leg is set on the inside of the shield machine 1, the oblique stretching in part of the Telescopic support leg
The outside of the shield machine 1；
The oblique angle in tail portion of the Telescopic support leg and the shield machine 1 is 30 ° -40 °；
The support device 3 of the Telescopic support leg is in direct contact tunnel.
The position that the support device 3 is contacted with tunnel is equipped with anti-skid device.
The hydraulic cylinder 2 uses great tonnage hydraulic cylinder.
For the support device 3 with hydraulic cylinder 2 into angle, the support device 3 is in direct contact tunnel.
The position that the support device 3 is contacted with tunnel is equipped with anti-skid device.
Operation principle：It is respectively arranged on first Telescopic support leg 5, second of the upper and lower, left and right of the shield machine 1
Telescopic support leg 6,7 and the 4th Telescopic support leg 8 of third Telescopic support leg can under the drive of the hydraulic cylinder 2 of its own
Freely to stretch, and control device can control the normal flexible or small distance of the part supporting leg in Telescopic support leg to stretch,
So as to fulfill steering.
Such as, when needing to be turned to the right, artificial one-key start connects the control device of the Telescopic support leg, control
