Embodiment Construction

[0025] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] figure 1 It is a top view of two sets of propulsion cylinders of a dual-mode shield machine in an embodiment of the present invention, figure 2 for figure 1 The cross-sectional view of A-A in the middle. The dual-mode shield machine includes multiple sets of propulsion cylinders arranged at uniform intervals along the circumference. figure 1 and figure 2 Only the schematic diagrams of two sets of propulsion cylinders are intercepted. Usually a dual-mode shield machine includes 19 sets of propulsion cylinders. One end of the propulsion cylinder is fixed, and the other end can move telescopically along the central axis of the cylinder.

[0027] Such as image 3 As shown, the dual-mode shield machine includes a connecting flange 1, a plurality of fixed seats 2 and multiple sets of propulsion cylinders 3, and multiple s...

Abstract

The invention discloses a dual-mode shield tunneling machine which comprises a connecting flange, multiple fixing seats and multiple groups of propelling oil cylinders. The propelling oil cylinders are evenly arranged along the circumference of the connecting flange and comprise cylinder bodies and piston rods located in the cylinder bodies, wherein the tail ends of the cylinder bodies are connected with the fixing seats through balls, the fixing seats are installed on the connecting flange, and the cylinder bodies of the propelling oil cylinders are sleeved by clamping plates. A deflection oil cylinder and an aligning oil cylinder are installed on each clamping plate, the deflection oil cylinders are used for adjusting movement of the front ends of the propelling oil cylinders in the circumferential radial direction, and the aligning oil cylinders are used for adjusting movement of the propelling oil cylinders in the circumferential tangential direction. Due to the fact that the dual-mode shield tunneling machine is provided with the deflection oil cylinders and the aligning oil cylinders, the deflection oil cylinders are used for adjusting movement of the front ends of the propelling oil cylinders in the circumferential radial direction and the aligning oil cylinders are used for adjusting movement of the propelling oil cylinders in the circumferential tangential direction, rolling rectifying and anti-rolling roles can be played.

Description

technical field [0001] The invention relates to a shield machine, in particular to a double-mode shield machine capable of automatic roll correction and anti-roll. Background technique [0002] Dual-mode shield machines usually use prefabricated concrete segment lining to support the tunnel, and rely on the friction between the segment and the tunnel wall to provide the driving reaction force. Since the cutter head of the dual-mode shield machine rotates in one direction, it is easy to cause the main machine to overturn, and even cause the main machine to overturn in severe cases. [0003] Therefore, it is necessary to design a dual-mode shield machine capable of automatic roll correction and anti-roll. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a double-mode shield machine capable of automatic roll correction and anti-roll. [0005] The technical solution of the present invention ...
