[0030] When in use, the vertical frame 2 is placed close to the tunnel wall so that the multiple groups of inspection units 3 are all close to the tunnel wall, and the visual inspection module 31 and the touch inspection module 32 are used to perform visual and tactile inspections on the tunnel wall respectively.

[0031] See also Figure 1-Figure 2 , tunnel wall inspection equipment, the visual inspection module 31 includes a fixing seat 311 fixed on the vertical frame 2, the fixing seat has two side faces, the side close to the front of the vehicle is the front side, and the front side of the fixing seat 311 is provided with an extension frame 312 protruding forward, and an image acquisition camera 313 is installed on the extension frame 312 for acquiring images of the tunnel wall conditions.

[0032] The touch inspection module 32 includes a fixed base 311, on which a movable frame 321 is slidably connected, and a pushing spring 322 is connected between the movable frame 321 and the fixed base 311. The movable frame 321 is provided with a knocking component 323. Under the push of the pushing spring 322, the knocking component 323 on the movable frame 321 is in close contact with the tunnel wall to realize knocking detection.

[0033] See also Figure 2-Figure 4, Tunnel wall inspection equipment, the knocking assembly 323 includes a running wheel 3231 rotatably mounted on a movable frame 321, the running wheel 3231 is pushed by a pushing spring 322 to keep in contact with the tunnel wall, and the running wheel 3231 rotates as the vehicle body 1 moves forward;

[0034] A crank 3232 is fixed on the axle of the traveling wheel 3231, and a knocking piece 3236 is elastically connected to the movable frame 321, and a convex plate 3237 is fixed on the knocking piece 3236. As the axle rotates, the protrusion 3233 at the end of the crank 3232 intermittently pushes the convex plate 3237 toward the side away from the tunnel wall, pushing the knocking piece 3236 away from the tunnel wall, and when the protrusion 3233 is away from the convex plate 3237, the knocking piece 3236 rebounds and knocks on the tunnel wall, and as the vehicle body 1 continues to move forward, continuous inspection of the tunnel wall is achieved;

[0035] When the walking wheel 3231 drives the protrusion 3233 to approach the protruding plate 3237 again, the protruding plate 3237 is pushed outward again, and when the protrusion 3233 moves to the outer side away from the tunnel wall, it is separated from the protruding plate 3237 again. At this time, the elastic connection rebounds and pushes the knocking member 3236 toward the tunnel wall again;

[0036] A connecting rod 3234 is fixed on the movable frame 321, and a knocking piece 3236 is slidably connected to the connecting rod 3234. A force storage spring 3235 is also connected between the knocking piece 3236 and the movable frame 321. When the knocking piece 3236 moves outward, the force storage spring 3235 is compressed, and the force storage spring 3235 rebounds to push the knocking piece 3236 to knock on the tunnel wall. A pickup 33 is also fixed on the movable frame 321. The pickup 33 is used to collect the sound when the knocking piece 3236 knocks on the tunnel wall. The audio is analyzed by the software system.
