Problems solved by technology

For example, lift trucks and forklifts are welded to double-layer or above brackets and cooperate with manual jacking to drag the ground-penetrating radar antenna close to the concrete wall of the secondary lining of the tunnel. This detection method is labor-intensive, labor-intensive, and the safety of high-altitude operations is not strong. Disadvantages. At the same time, in the process of artificially dragging the ground penetrating radar antenna, due to the upward manual operation, it is extremely easy to cause worker fatigue, which makes the coupling between the ground penetrating radar antenna and the secondary lining concrete surface poor, which eventually leads to detection The radar spectrum cannot meet the requirements of the detection results and cannot give reliable detection

Abstract

The invention relates to a holding rail type automatic slip detecting device for tunnel second lining defect detection. The detecting device is composed of spherical guide rails, body brackets, adjustable pressing assemblies, driving brake assemblies, distance measuring assemblies, and ground penetrating radar antenna assemblies. The spherical guide rails are installed at the second lining concrete wall vault, haunches at the two sides, and side walls at two sides of a tunnel by screw rods. The body brackets are assembled and connected by bolts. The adjustable pressing assemblies consist of adjustable frames, adjusting screw rods, compression springs, and compression nuts. The driving brake assemblies include direct-current servo motors, controllers, power supplies, electromagnetic brakes,and wheels. The distance measuring assemblies include ranging coders. The ground penetrating radar antenna assemblies consist of shielded antennas, batteries, fiber cables, radar hosts, wireless receiving modules, and laptops. Therefore, tunnel detection is carried out conveniently and quickly; the detection time is shortened; and the efficiency and reliability of tunnel defect detection are improved.

Description

technical field [0001] The invention belongs to the technical field of robot automatic detection, and in particular relates to a rail-holding type automatic slip detection device used for detection of defects in the second lining of tunnels. Background technique [0002] The quality of the secondary lining of highway and railway tunnels is the key point of the tunnel support structure. The quality of the tunnel support structure system is related to the safety of the entire tunnel. Due to the concealment of the tunnel lining structure, lining voids, thickness Insufficient water leakage in tunnels, secondary lining falling blocks and other serious quality problems, the geological radar method can quickly detect the quality of secondary lining by using electromagnetic waves to detect shallow layers of the ground surface, and analyze it according to the radar map ,determination. Existing detection of secondary lining defects in tunnels requires the use of cranes, forklifts, er...
