Double-power self-propelled detection platform

Technical Field

The utility model relates to the technical field of engineering machinery, in particular to a double-power self-propelled detection platform.

Background

Tunnels are buildings that are built underground or under water or in mountains, paved with railways or built on roads for the passage of motor vehicles. The tunnel type tunnel is divided into mountain tunnels, underwater tunnels and urban tunnels according to the positions of the tunnel type tunnel. A tunnel called mountain tunnel which passes under a mountain or a hilly in order to shorten a distance and avoid a large slope; what is known as an underwater tunnel passing under a river or the sea floor for crossing a river or a strait; urban tunnels are called urban underground crossings to accommodate the need for railways to pass through large cities. The most established of the three types of tunnels is mountain tunnels. In the process of railway tunnel construction and maintenance, the inner wall of the tunnel lining may have defects of cracks, holes, leakage, virtual blocks and the like, and the phenomena of ballast dropping, water seepage, collapse and the like of the tunnel lining can be caused, so that potential danger is caused to train operation.

The application of the application number CN201920791097.0 provides a tunnel detection device, including removing the carrier and setting up detect the arm on the carrier, detect the arm including articulated big arm on the carrier and with big arm articulated forearm, be provided with on the forearm along the radial flexible detection module of tunnel. Can follow tunnel radial flexible through setting up detection module, when having the barrier on tunnel inner wall, only detection module radial contraction can realize avoiding the barrier, easy operation need not to make the removal carrier stop and operate the detection arm and realize avoiding the barrier, convenient operation does not influence work efficiency. The problem of tunnel detection device among the prior art need the parking keep away the barrier under the condition of touching the barrier, reduce efficiency is solved. However, the detection arms are still inflexible in actual detection, if the detection arms can only detect in one direction, two sets of detection arms are needed to be configured in two directions, so that the cost is greatly increased; for example, the actual detection needs to detect the arch and the side wall of the tunnel, the heights of the two positions are different, the detection arms with the same specification cannot be used for detection, and the detection arms with different extension lengths can be only arranged on the detection vehicle, so that the cost is increased, and the later maintenance is not facilitated.
