A mobile dynamic monitoring pan-tilt in a tunnel

Abstract

The invention discloses a movable dynamic monitoring platform in a tunnel, which comprises a monitoring platform that moves back and forth along the longitudinal extension direction of the monitored tunnel, a moving track for the monitoring platform to move back and forth, and a device that drives the monitoring platform to move back and forth on the moving track. The mobile mechanism and the suspension mechanism that suspend the mobile track on the tunnel inner wall of the monitored tunnel, the upper end of the suspension mechanism is fastened and fixed on the inner wall of the tunnel, and the mobile track is fixed below the suspension mechanism; Layout in the extension direction; the moving mechanism includes moving wheels, drive motors and mounting brackets; the monitoring platform includes a supporting frame, a crack detector, a temperature and humidity detector, and a power supply and control device installed in the supporting frame; the supporting frame is located under the mounting bracket and It is fixedly mounted on the mounting bracket. The invention has the advantages of simple structure, reasonable design, convenient use and operation, good use effect, and can simply, quickly and effectively complete the tunnel crack detection process.

Description

Technical field [0001] The invention relates to a monitoring device, in particular to a movable dynamic monitoring platform in a tunnel. Background technique [0002] With the development of my country's economy and technology and the increasing comprehensive national strength, tunnel construction has also achieved rapid development. In my country, the proportion of railway tunnels is relatively large. At the same time, the corresponding tunnel diseases are becoming more and more prominent. As of the end of 2004, 65% of the tunnels in my country have entered the maintenance period. [0003] Lining cracks are the most common tunnel disease. It is an important cause of failure or collapse of the lining structure. Because the lining of the tunnel is in the complex surrounding rock geological mass, the load imposed on the lining structure of the tunnel due to different reaction conditions by special strata and Geological, design, and construction factors such as track vibration and te...

Problems solved by technology

[0011] At present, the tunnel defect detection methods mainly adopt artificial naked eye detection and manual instrument detection in China. The former is highly subjective in judging cracks, and the detection results are difficult to guarantee and cannot be completed within a certain period of time; although the latter can guarantee the accuracy of detection , but the efficiency is the same as that of manual detection, and it cannot be completed within a certain period of time

In addition to the above two detection methods used in China, foreign countries mainly use automation technology, that is, vehicle-mounted image detection systems. The detection system cannot achieve fast and accurate crack detection, and cannot effectively extract crack information; the tunnel crack detection system developed by Hanyang University in South Korea, although the detection accuracy is relatively high, but the speed of the vehicle is relatively slow, and it is currently in the experimental stage. stage, the corresponding solutions to the actual situation of the tunnel are not yet perfect, and need to be further optimized
