Problems solved by technology
[0003] Tunnel full-face boring machine is different from other construction machinery. Due to the complicated manufacturing process and high technical added value, only a few countries in the world can produce it, and the cost is high.
At present, there is no major problem in our country's design capabilities, but due to lack of experience, there is still a long way to go to improve its performance

The invention discloses a tunnel boring machine cutter head attitude detection device. The upper side, lower side, left side and right side of the axial outer cylindrical surface of a cutter head shield body in an arm protecting sleeve are respectively provided with a large spherical hinge; the large spherical hinges and their respective attitude plates form spherical hinge pairs; six hydraulic cylinders arranged at the upper sides, left sides and right sides of radial cross sections of the cutter head shield body axially pass through the arm protecting sleeve, and then, the piston rods of the six hydraulic cylinders are hinged with attitude plates through small ball hinges respectively, and the bottoms of the hydraulic cylinders are hinged with box bodies through small ball hinges respectively; four hydraulic cylinders arranged at the lower sides of the radial cross sections of the cutter head shield body, every two hydraulic cylinders adopted as one group, axially pass through the arm protecting sleeve, and then, the piston rods of the hydraulic cylinders are hinged with attitude plates through small ball hinges respectively, and the bottoms of the hydraulic cylinders are hinged with box bodies through small ball hinges respectively; and each hydraulic cylinder is connected with a respective hydraulic cylinder control detection oil path. According to the tunnel boring machine cutter head attitude detection device of the invention, the initial pressing pressure of the hydraulic cylinders can be adjusted through proportional overflow valves; the reset of the hydraulic cylinders can be realized through the uninterrupted work of quantitative pumps; oil inlets and oil outlets can be switched through electromagnetic two-position four-way reversing valves, so that the positions of the hydraulic cylinders can be adjusted when the hydraulic cylinders do not work; and real-time detection of attitude forces and displacement can be realized through pressure and displacement sensors.
Description
technical field [0001] The invention relates to an attitude detection device, in particular to an attitude detection device for a cutter head of a tunnel full-section boring machine. Background technique [0002] Tunnel full-face tunnel boring machine is a highly intelligent tunnel construction major technical engineering equipment integrating machinery, electricity, hydraulics, light, and computer. In developed countries, the construction of tunnel boring machines has accounted for more than 90% of the total tunnels. With the rapid development of China's national economy and the continuous acceleration of domestic urbanization, China's urban subway tunnels, hydraulic tunnels, cross-river tunnels and railway tunnels will require a large number of tunnel boring machines. [0003] Tunnel full-face tunnel boring machine is different from other construction machinery. Due to the complicated manufacturing process and high technical added value, only a few countries in the world ...
