Problems solved by technology

[0003] In order to solve the problems of frequent obstacle avoidance, large obstacle avoidance size and detection blind spots in existing tunnel lining detection devices, the present invention provides a tunnel lining state detection device. The tunnel lining state detection device is based on its huge The structural characteristics of the catenary grid, the mechanical curved arm is designed, and the design idea of ​​the straight-line lifting of the mechanical arm is changed, which can effectively solve all the above problems. It is a brand new idea and means for the large-scale mechanized operation mode of tunnel lining, fully automatic operation, The detection speed is greatly improved, the response speed is fast, the movement range is extremely small, there is basically no obstacle avoidance behavior, the detection blind spot is completely eliminated, and the performance is stable

Abstract

The invention discloses a tunnel lining state detection device which includes a mobile work platform (40). The lower end of a mechanical bent arm (10) is connected with the work platform (40) througha rotating gear shaft (11). The mechanical bent arm (10) is curved and telescopic. The rotating gear shaft (11) is connected with a first drive mechanism which can drive the mechanical bent arm (10) to swing around the rotating gear shaft (11) as an axis. A radar antenna support trolley (30) is disposed on a slip rope (20). The radar antenna support trolley (30) can move along the slip rope (20).A geological radar antenna (31) is fixed on the radar antenna support trolley (30). The mechanical bent arm is designed on the tunnel lining state detection device, and the design idea of linear lifting of a mechanical arm is changed. The detection speed is greatly improved. The response is quick. The motion range is very small. There is basically no obstacle avoidance behavior. The detection blind area is completely eliminated. The device has stable performance.

Description

technical field [0001] The invention relates to the field of tunnel detection equipment, in particular to a tunnel lining state detection device. Background technique [0002] In the existing tunnel lining non-destructive testing technology, the ground radar detection method is the most important method, and the ground radar detection mainly includes manual and vehicle-mounted detection methods. At present, there is no feasible and effective method for rapid detection of the ground surface radar at a long distance on the lining surface to be measured, and it is necessary to use a vehicle to place it near the surface of the tunnel lining. my country has developed the first tunnel status inspection vehicle. One end of each mechanical arm is fixedly installed with ground radar, and the control system is used to operate each mechanical arm to move on the vehicle body to detect the tunnel lining. However, due to the structural characteristics of the manipulator system, the sens...
