The invention discloses a tunnel hole shrinkage anti-clamping vehicle-mounted side wall radar servo lifting device. The device comprises a radar, an extension mechanism, a driving mechanism and a lifting mechanism; the extension mechanism includes a base and an extension rod capable of performing an extension motion on the base; the radar is arranged at the outer end of the extension rod; the driving mechanism is used for driving the extension rod to perform the extension motion; and the lifting mechanism is arranged below the extension mechanism. The device is characterized in that a horizontal revolving mechanism is additionally arranged between the extension mechanism and the lifting mechanism; the horizontal revolving mechanism includes an upper turntable and a lower turntable; the upper turntable is hinged to the middle part of the base of the extension mechanism; the base can rotate up and down around a hinge point; the lower turntable is connected with the lifting mechanism; a rotating bearing is arranged between the upper turntable and the lower turntable; a return spring is arranged on the upper turntable; and the base and the upper turntable are connected through a length-adjustable support hinge rod. The device has the beneficial effects of capability of automatically avoiding projections in a tunnel, good flexibility, simple structure and convenience for disassembly and assembly.
Description
technical field [0001] The invention relates to a detection device for the side wall of a tunnel, in particular to a radar servo lifting device for tunnel shrinkage and anti-truck vehicle side wall. Background technique [0002] The detection of the health status of the tunnel was initially judged by naked eye observation. This detection method is poorly representative and can only be drilled with a small number of samples, which is difficult to fully reflect the overall health status of the tunnel. In recent years, the non-destructive testing method of ground radar has good flexibility, and the lifting ground radar is used to scan longitudinally in the tunnel, which is widely used in tunnel detection. [0003] Overseas, Germany has developed a GeoRail-Xpress comprehensive inspection vehicle, and Japan has developed a tunnel lining inspection system using multi-channel geological radar technology, which can lift the geological radar well for inspection of operational railway...
