Technical Field

[0001] This invention relates to the field of tunnel inspection equipment technology, specifically to a tunnel wall inspection device. Background Technology

[0002] Tunnel wall inspection involves multiple aspects and is a crucial step in ensuring the structural safety and proper functioning of the tunnel. It aims to comprehensively assess the tunnel's structural integrity and safety. Tunnel wall inspection includes visual and tactile inspections. Visual inspection involves visually observing the tunnel walls to identify cracks, spalling, bulges, and other abnormalities.

[0003] Touch testing involves using tools to tap the tunnel wall to check for hollow sounds in the lining.

[0004] The above-mentioned inspection items are performed by different personnel or equipment. The tunnel wall inspection equipment provided in this solution combines the above two functions through structural design, and can simultaneously perform visual inspection and percussion inspection. Summary of the Invention

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1 The tunnel wall inspection equipment includes a vehicle body 1, a vertical frame 2 mounted on the vehicle body 1, and multiple inspection units 3 arranged along the height direction on the vertical frame 2; each inspection unit 3 includes a visual inspection module 31 and a touch inspection module 32.

[0030] When in use, the vertical frame 2 is placed close to the tunnel wall, so that multiple inspection units 3 are all close to the tunnel wall. 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] Please see Figures 1-2 The tunnel wall inspection equipment, visual inspection module 31 includes a fixed seat 311 fixed on the vertical frame 2. The fixed seat has two sides, with the side closer to the front of the vehicle as the front side. On the front side of the fixed seat 311, there is an extension frame 312 that protrudes forward. An image acquisition camera 313 is installed on the extension frame 312 for acquiring images of the tunnel wall.

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

[0033] Please see Figures 2-4The tunnel wall inspection equipment, the tapping component 323 includes a traveling wheel 3231 rotatably mounted on a movable frame 321. The traveling wheel 3231 is in contact with the tunnel wall under the push of the push spring 322. As the vehicle body 1 moves forward, the traveling wheel 3231 rotates.

[0034] A crank 3232 is fixed on the axle of the traveling wheel 3231, and a striking element 3236 is elastically connected to the movable frame 321. A protruding plate 3237 is fixed on the striking element 3236. As the axle rotates, the protrusion 3233 at the end of the crank 3232 intermittently pushes the protruding plate 3237 away from the tunnel wall, pushing the striking element 3236 away from the tunnel wall. When the protrusion 3233 moves away from the protruding plate 3237, the striking element 3236 rebounds and strikes the tunnel wall. As the vehicle body 1 moves forward continuously, the tunnel wall is continuously inspected.

[0035] When the traveling wheel 3231 drives the protrusion 3233 to approach the protrusion plate 3237 again, it pushes the protrusion plate 3237 outward again. When the protrusion 3233 moves to the outside away from the tunnel wall, it disengages from the protrusion plate 3237 again. At this time, the elastic connection rebounds and pushes the striking piece 3236 to the tunnel wall again.

[0036] A connecting rod 3234 is fixed on the movable frame 321. The striking piece 3236 is slidably connected to the connecting rod 3234. A storage spring 3235 is also connected between the striking piece 3236 and the movable frame 321. When the striking piece 3236 moves outward, it compresses the storage spring 3235. The storage spring 3235 rebounds and pushes the striking piece 3236 to strike the tunnel wall. A microphone 33 is also fixed on the movable frame 321. The microphone 33 is used to collect the sound when the striking piece 3236 strikes the tunnel wall. The audio is analyzed by the software system. If an empty sound is detected, a warning message is issued to the personnel following behind for handling.

[0037] This invention does not include the analysis and processing of acquired image and audio information, or the method for judging the working condition of tunnel walls. This invention only discloses a mechanical device for simultaneously acquiring images and tapping audio of tunnel walls.

[0038] Please see Figure 1 and Figures 5-6The tunnel wall inspection equipment has a mounting platform 11 on the vehicle body 1. A retraction mechanism 4 is connected between the mounting platform 11 and the vertical frame 2. The retraction mechanism 4 is used to control the vertical frame 2 to be retracted horizontally or erected and pushed away from the mounting platform 11, so as to prevent the mounting platform 11 from being too close to the tunnel wall when the vertical frame 2 is erected. The retraction mechanism 4 includes a first support rod 41, a second support rod 42, a mounting rod 43, a first telescopic rod 44, and a second telescopic rod 45. The first support rod 41 and the second support rod 42 are hinged to the mounting platform 11. At the same time, the mounting rod 43 is hinged to the top of the first support rod 41 and the second support rod 42, and the tail end of the mounting rod 43 is also hinged to the vertical frame 2. The first support rod 41 and the second support rod 42 are parallel, and the mounting rod 43, the mounting platform 11, the first support rod 41, and the second support rod 42 form a parallelogram.

[0039] The two ends of the telescopic rod 44 are respectively hinged to the mounting platform 11 and the top of the support rod 41, and are used to control the swing posture of the support rod 41 and the support rod 42, that is, to control the vertical frame 2 after it is erected to move away from or close to the mounting platform 11.

[0040] The two ends of the telescopic rod 45 are respectively hinged to the mounting rod 43 and the vertical frame 2, and are used to control the vertical frame 2 to switch between vertical and horizontal positions;

[0041] When telescopic rod 2 extends, it pushes the vertical frame 2 from a flat position to a vertical position. When telescopic rod 1 extends, it pushes the vertical frame 2 away from the outside of the mounting platform 11. During inspection, first control the extension of telescopic rod 1, then start the extension of telescopic rod 2 45. Then the vehicle body 1 drives the vertically positioned vertical frame 2 into the tunnel and closes to the tunnel wall.

[0042] When it is necessary to retract the vertical frame 2, first activate the telescopic rod 44 to retract, so that the vertical frame 2 moves away from the tunnel wall and closer to the mounting platform 11. Then activate the telescopic rod 45 to retract, so that the vertical frame 2 changes from the vertical position to the horizontal position.

[0043] Please see Figure 1 and Figure 5 The tunnel wall inspection equipment has a motor 5 installed inside the vehicle body 1, and the mounting platform 11 is fixed on the output shaft of the motor 5. The angle of the mounting platform 11 can be rotated by the motor 5, so that after the inspection is completed, the flat vertical frame 2 can be adjusted to be placed along the length of the vehicle body 1, thereby improving safety.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
