The invention relates to a rail tunnel detecting operating vehicle. Two bogies are arranged under a vehicle body; a hydraulic transmission device for providing power is hung under the vehicle body; a driver chamber and a tunnel detecting device for detecting tunnel lining diseases are arranged on the vehicle body. The tunnel detecting device comprises an LED stroboscopic illumination lamp and a camera, a thermal infrared imager, a laser scanner, a ground penetrating radar, a high-accuracy vehicle speed sensor, and a positioning navigation device which are connected with a computer arranged in the driver chamber, wherein the LED stroboscopic illumination lamp and the camera are used for collecting long-distance images of tunnel walls; the thermal infrared imager is used for collecting the data of thermal images of the inner walls of a tunnel; the laser scanner is used for high-accuracy measurement of tunnel section parameters, inspecting fine section deviations on the surfaces of the inner walls of the tunnel, and measuring a high-accuracy 3D shape required by the tunnel inspection; the ground penetrating radar is used for performing non-destructive detection on the inner part of a liner of the inner walls of the tunnel; the high-accuracy vehicle speed sensor is used for collecting the speed information of the operating vehicle through the computer; the positioning navigation device is used for collecting the position information of the operating vehicle through the computer. The rail tunnel detecting operating vehicle disclosed by the invention is used for detecting the rail tunnel, quickly arrives at the site, and is high in detecting speed, high in detecting efficiency, and high in accuracy.
Description
Technical field [0001] The invention relates to a railway vehicle, in particular to a railway tunnel inspection vehicle used for detecting railway tunnel lining cracks, lining water seepage, water leakage, deformation, voiding and other diseases. Background technique [0002] At present, the diseases of domestic railway tunnels mainly include lining cracks, water seepage, water leakage, deformation, voids, etc., which pose a serious threat to the operation of railway rolling stock and EMUs. The detection of these diseases mainly adopts manual visual inspection. For lining cavities, tapping and drilling sampling methods must be adopted, which not only has low detection efficiency and poor accuracy, but also has a large number of missed inspections. Therefore, the detection of railway tunnel lining diseases urgently needs to adopt advanced methods such as automated measurement and computer-aided disease analysis. National Railways and various urban rail transit operating units have...
