[0031] Then the operator can push the handrail 29 to move the entire detection device to different positions in the highway tunnel for detection by using the flexible steering function of the universal wheel 28, which improves the convenience and working efficiency of the device in the tunnel. After reaching the appropriate position, the second electric telescopic rod 3 is started to drive the fixed frame 4 to adjust the height, so that it can align with the area to be detected on the top of the highway tunnel, facilitating the crack detection work. Then the third electric telescopic rod 16 is started, and its output end drives the stable table 17 to move up and down, which can accurately adjust the height of the detection components from the tunnel top according to the specific situation and detection requirements of the tunnel top, ensuring that the detection components are in the best working position to obtain clear and accurate detection data.
