Problems solved by technology

[0005] Consulting the existing technical literature, it can be seen that most of the existing TBM test platforms are cutter head rock breaking simulation test platforms or comprehensive simulation test platforms. The comprehensive test platform is expensive. It is not comprehensive enough to comprehensively consider the test conditions under multiple factors such as

Abstract

The invention discloses a multi-factor simulation test device for TBM gripper shoes bracing tightly against surrounding rock. A containing box comprises a containing box shell, surrounding rock side wall simulation blocks and a front baffle of the containing box; a TBM supporting and pushing mechanism comprises a pushing hydraulic cylinder and a main beam hinged base, gripper shoes, a front connecting plate of the main beam, a gripper shoes hydraulic cylinder and a gripper shoes connecting base, four pushing hydraulic cylinders, a base of a rear supporting beam, a rear supporting beam, four saddle rack supporting hydraulic cylinders, two gripper shoes hydraulic cylinders, a saddle rack and a main beam; each hydraulic cylinder is connected with corresponding electro-hydraulic controlling oil-way. Proportional pressure reducing valve of each hydraulic cylinder controlling oil-way controls the simulation of different propulsive force, different supporting torques of the saddle rack and different supporting force of gripper shoes to be achieved; the position of the pushing hydraulic cylinder and the main beam hinged base can be changed to achieve the simulation of pushing direction and tunnelling direction in different angles; the simulation of different contact surfaces between the gripper shoes and the surrounding rock can be achieved through the detachment and installation of five parts of gripper shoes bodies. In a small space, multi-factor gripper shoes bracing tightly against surrounding rock experiment and research can be carried out with low cost.

Description

technical field [0001] The invention relates to a simulation test device, in particular to a multi-factor simulation test device for tightening surrounding rock with TBM boots. Background technique [0002] Full-face rock tunnel boring machine (TBM) is a large factory tunnel construction operation system integrating mechanical, electronic, hydraulic and laser technologies. The TBM method has the advantages of fast excavation speed, short construction period, good working environment, friendly to the ecological environment, and high comprehensive benefits. It is an important choice for tunnel construction methods at home and abroad. With the rapid development of China's national economy and the acceleration of domestic urbanization, a large number of TBMs will be required in China's urban subway tunnels, hydraulic tunnels, cross-river tunnels, and railway tunnels. [0003] TBM is different from other construction machinery. Due to the complicated manufacturing process and hi...
