Detection device for tunnel detection vehicle

Abstract

The invention discloses a detection device for a tunnel detection vehicle. The detection device consists of five detection arms which are arranged on a detection vehicle platform (7) sequentially, wherein each detection arm consists of six parts, namely a radar trolley (1), a hydraulic winch and steel wire rope (2), a multi-stage plunger hydraulic cylinder (3), a multi-stage telescopic arm (4), a detection arm seat and a swing hydraulic cylinder (6). When the detection device works, the multi-stage plunger hydraulic cylinders (3) drive the multi-stage telescopic arms (4) to stretch; the swing hydraulic cylinders (6) adjust the swing angles of the detection arms; and the radar trolleys (1) are arranged on five appointed detection lines within a range of 180 degrees of the section of a tunnel, and are used for detecting the lined inner wall of the tunnel. After the detection, the hydraulic winch and steel wire ropes (2) drag the radar trolleys (1) to make the multi-stage telescopic arms (4) contract; and the swing hydraulic cylinders (6) are adjusted to drive the radar trolleys (1) to reach trolley accommodation positions.

Description

Technical field [0001] The invention relates to a new railway vehicle—a tunnel detection vehicle, in particular to a detection device on the tunnel detection vehicle. Background technique [0002] During the construction and maintenance of railway tunnels, there may be defects such as cracks, holes, leakage, and virtual blocks in the inner wall of the tunnel lining, which will cause ballast, water seepage, and collapse of the tunnel lining, and pose potential dangers to train operation. Therefore, a device is needed to detect the inner wall of the tunnel lining, so as to detect it in time and take remedial measures. [0003] At present, in China, simple flat cars are used to manually roll the tunnel, and the detection radar is manually supported for detection. The inner wall of the tunnel lining is detected along one line each time, and a strip-shaped area is detected. The maximum detection speed is 5km / h. Contents of the invention [0004] In order to improve the efficie...
