[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] See also Figure 1-Figure 4 The utility model provides a mounting plate 1 and an arc-shaped rod 9. Mounting parts 2 are fixed on both sides of the top of the mounting plate 1. A rotating shaft 3 is rotatably mounted on the inner wall of the mounting part 2. A rotating rod 4 is fixed on the outer wall of the rotating shaft 3. A first connecting part 5 is rotatably mounted on the other end of the rotating rod 4. A curved rod 6 is rotatably mounted on the other end of the first connecting part 5.

A transmission mechanism 12 is provided at the driving end of the driving motor 11.

[0023] The transmission mechanism 12 can mainly drive the rotating rod 4 to rotate, and further drive the curved rod 6 to rotate, thereby driving the equipment to unfold, and then driving the second wide-angle video recording device 10 to unfold, and further cracks on the tunnel surface can be detected.

[0024] Further as Figure 1 , Figure 2 As shown, it is worth to explain in detail that the transmission mechanism 12 includes a connecting rod 121, the connecting rod 121 is fixedly installed on the driving end of the driving motor 11, and the two ends of the connecting rod 121 are fixed with worms 122;

[0025] The transmission mechanism 12 also includes two worm wheels 123, which are respectively fixed to one end of the rotating shaft 3. The worm wheels 123 are meshingly connected with the worm 122. When the worm 122 is driven by the motor 11 to rotate forward, the crack detection device can be driven to unfold. When the worm 122 is driven by the motor 11 to rotate reversely, the crack detection device can be stored.

[0026] By starting the driving motor 11 , it can drive the connecting rod 121 to rotate, further drive the worm 122 to rotate, and further drive the worm wheel 123 to rotate, thereby enabling the first connecting member 5 to rotate.

[0027] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that both ends of the arc rod 9 are rotatably mounted on the other end of the second connecting member 8.

[0028] This solution has the following working process: when it is necessary to detect cracks on the tunnel surface, by connecting one end of the traction rod 18 to the rear frame of the operating vehicle, and then starting the drive motor 11, it is further possible to drive the connecting rod 121 to rotate, thereby driving the worm 122 to rotate, and then driving the worm wheel 123 to rotate, thereby driving the rotating shaft 3 to rotate, and further driving the rotating rod 4 to rotate, and then through the rotating rod 4, it can drive the first connecting member 5 to rotate, and then drive the curved rod 6 to unfold, and then through the cooperation between the second connecting member 8, it can enable the detection equipment to be unfolded, and after unfolding, it is as follows Figure 4 As shown, the crack detection setting can be close to the curvature of the outer wall of the tunnel, so that the detection effect is more outstanding, and then through the cooperation between the first wide-angle video recording device 7 and the second wide-angle video recording device 10, the cracks on the tunnel surface can be fully detected.

[0029] According to the above working process, it can be known that: when cracks are detected on the tunnel surface, by starting the servo cylinder 14, the mounting block 15 can be driven to slide, and further the marking pen 16 can be driven to slide, so that the marking pen 16 fits with the tunnel surface, and then the cracked area can be marked, so as to facilitate maintenance personnel to find the cracks and carry out maintenance.

[0032] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that movable wheels 17 are fixed to the bottom end of the mounting plate 1 in a rectangular shape.
