Abstract

The invention discloses a support and steering hydraulic system for an experiment table of a rock tunnel boring machine. The support and steering hydraulic system comprises an oil source, a gripper shoe oil channel and a pitching oil channel. The oil source comprises an oil-conveying pipeline. One end of the oil-conveying pipeline is communicated with an oil tank and the other end of the oil-conveying pipeline is sequentially connected with a filter, a metering pump, a first check valve and an oil source cut-off valve. The gripper shoe oil channel comprises a first hydraulic cylinder and a second hydraulic cylinder. A saddletree is capable of performing movement with cylinder barrels of the first hydraulic cylinder and the second hydraulic cylinder along axial directions of the first hydraulic cylinder and the second hydraulic cylinder. The pitching oil channel comprises two identical pitching modules. The saddletree is driven by the two pitching modules to perform up-down motion. The support and steering hydraulic system for the experiment table of the rock tunnel boring machine has following beneficial effects: the system can be matched with a controller for design, correction and deviation load; when a cutter disc deviates, the controller receives a deviation load signal and automatically controls steering, pitching and rotation motion in a real-time manner so that flexibility and effectiveness of correction and deviation are greatly improved in order to enhance tunneling precision and efficiency of the rock tunnel boring machine.

Description

technical field [0001] The invention relates to a supporting and steering hydraulic system, in particular to a supporting and steering hydraulic system for a test bench of a hard rock roadheader. Background technique [0002] Hard rock tunnel boring machine (abbreviated as TBM) is the key equipment for underground tunnel construction in the fields of railway, highway, water conservancy and urban construction. It is a kind of tunnel boring equipment integrating mechanical, electrical, hydraulic and information technologies. In recent years, with the continuous follow-up of my country's infrastructure construction, a large number of traffic projects and resource transportation projects need to carry out tunnel excavation construction under extremely complex geological conditions. Hard rock tunnel boring machines are undoubtedly the first choice for such projects . [0003] Hard rock roadheaders are technically complex and have high added value, reflecting the level of a country...
