Tunnel detection vehicle

Abstract

The invention discloses a tunnel detecting vehicle, which relates to the technical field of tunnel detecting equipment. The technical scheme mainly comprises a vehicle body, a detecting mechanism anda recording mechanism are installed on the vehicle body, and an arc-shaped box top plate arranged concentric with the tunnel top wall is fixed on the vehicle body. A detection mechanism includes a support plate concentrically fixed to a side of the box top plate remote from the vehicle body, a plurality of detection rods are arranged on the support plate along the radial direction through the boxtop plate, the plurality of detection rods are uniformly distributed along the circumference of the support plate, the detection rods slide relative to the support plate and the box top plate along the radial direction, the detection rods are connected with elastic resetting members, and one end of the detection rods close to the vehicle body is provided with a drawing line assembly; The recordingmechanism comprises a storage roller and an unwinding roller, wherein the storage roller is connected with a driving assembly for driving the storage roller to rotate. The invention solves the problem that the prevention measures cannot be made by photographing and collecting the internal cracks of the tunnel by the camera at present, and can detect the position of the cracks with high probability before the cracks are generated, so that the prevention measures can be made.

Description

technical field [0001] The invention relates to the technical field of tunnel inspection equipment, and more specifically, it relates to a tunnel inspection vehicle. Background technique [0002] Due to the influence of geological conditions, topographical conditions, climatic conditions, and various factors in the design, construction, and operation processes, tunnels are more prone to diseases than ordinary roads during long-term use, such as lining cracking and corrosion, water leakage and freezing damage, etc. These diseases It not only affects the function of the tunnel, but also seriously endangers driving safety. Therefore, detecting the tunnel becomes an important security assessment behavior. [0003] The prior art refers to the Chinese invention patent application whose publication number is CN108177579A, which discloses a tunnel inspection vehicle, including an industrial camera, a vehicle body, wheels connected to the vehicle body, and an encoder connected to th...

AI Technical Summary

Problems solved by technology

However, the invention application has the following disadvantages: Since the pattern captured by the industrial camera can only visually see the cracked position, it cannot observe the deformed part of the tunnel that has not yet cracked, which affects the safety assessment

This application for the invention can avoid the serpentine movement of the rail car when it is moving, and ensure the accurate positioning of the rail car perpendicular to the direction of travel, but it has the following disadvantages: the detection equipment on the tunnel inspection car can detect the conditions on both sides of the tunnel. The part where the top wall has been deformed and may crack cannot be detected, which affects the safety assessment

[0005] In summary, the existing tunnel inspection vehicles cannot detect the parts where the tunnel top wall has been deformed and may crack, which affects the safety assessment of the tunnel and makes it impossible to take effective preventive measures in advance
