[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1-3 The present invention provides a highway tunnel inspection device, comprising:

[0033] The base 1 has a base plate 2 movably connected to it, and several legs 3 are fixedly connected to it.

[0034] The outrigger 3 is used to connect with the traction equipment, and the base plate 2 can move on the base 1 to facilitate adjustment of the base 1 according to usage requirements.

[0035] The first detection component includes a turntable 4, which is rotatably connected to a base plate 2. A first motor 5 is fixedly connected to the base plate 2 and is driven by the turntable 4. A first electric telescopic rod 6 is movably connected to the turntable 4. A protective cylinder 7 is fixedly connected to the base plate 2 and a top plate 8 is fixedly connected to the protective cylinder 7. A first support rod 9 is movably connected inside the top plate 8. One end of the first support rod 9 is hinged to the first electric telescopic rod 6, and the other end of the first support rod 9 is fixedly connected to a first detection element 10.

[0036] The first electric telescopic rod 6 can extend or retract, which can drive the first support rod 9 to move. The first support rod 9 is movably connected to the top plate 8. The first detection element 10, which is fixedly connected to the other end of the first support rod 9, can also move, so the detection angle of the first detection element 10 can be adjusted. The first motor 5 drives the turntable 4 to rotate. The first electric telescopic rod 6 is set on the turntable 4, so it can drive the first support rod 9 to rotate and also adjust the detection angle, thereby adjusting different detection areas.

[0037] The second detection component includes several first columns 11, each first column 11 is rotatably connected to a second support rod 12, a second motor 13 is fixedly connected to the base plate 2, the second motor 13 is drivenly connected to the second support rod 12, and a second detection element 14 is fixedly connected to the end of the second support rod 12 away from the second motor 13.

[0038] The second motor 13 drives the second support rod 12 to move, and the second detection element 14 is fixed on the second support rod 12. Therefore, the detection angle can be adjusted. The detection area of ​​the second detection element 14 is different from that of the first detection element 10, which can expand the detection range and improve the detection efficiency.

[0039] The scheme is further optimized by fixing an arc-shaped plate 15 inside the top plate 8, rotating a ball 16 inside the arc-shaped plate 15, and inserting the first support rod 9 inside the ball 16.

[0040] The ball 16 rotates within the arc plate 15, which allows the first support rod 9 to swing within a large range, facilitating the adjustment of the detection area by the first detection element 10.

[0041] In a further optimized design, a circular tube 17 is fixedly connected to the substrate 2, and a first rotating shaft 18 is fixedly connected to the turntable 4. The first rotating shaft 18 is inserted into the circular tube 17 and rotates within the circular tube 17. A circular ring 19 is fixedly connected to the turntable 4, and a toothed ring 20 is fixedly connected to the outside of the circular ring 19. A first gear 21 is fixedly connected to the output end of the first motor 5, and the first gear 21 meshes with the toothed ring 20.

[0042] The first motor 5 drives the first gear 21 to rotate, and the first gear 21 drives the gear ring 20 to rotate, thus enabling the turntable 4 to rotate. The first rotating shaft 18 rotates inside the circular tube 17, which enables the turntable 4 to rotate and connect with the substrate 2.

[0043] In a further optimized design, a number of conductive rings 22 are fixedly connected to the outer edge of the turntable 4, a second column 23 is fixedly connected to the base plate 2, and a number of conductive springs 24 are fixedly connected to the second column 23. The conductive springs 24 abut against the conductive rings 22, and the conductive rings 22 are electrically connected to the first electric telescopic rod 6.

[0044] When the turntable 4 rotates, the conductive spring 24 is always in contact with the conductive ring 22, which can keep the first electric telescopic rod 6 energized at all times.

[0045] In a further optimized design, through holes are provided on both the first column 11 and the second support rod 12, and a second rotating shaft 25 is inserted through the through holes. The first column 11 and the second support rod 12 are rotatably connected through the second rotating shaft 25.

[0046] The first column 11 and the second support rod 12 are rotatably connected by the second pivot 25.

[0047] In a further optimized design, a disc 26 is fixedly connected to the output end of the second motor 13, and a fixed column 27 is fixedly connected to the disc 26. The fixed column 27 is eccentrically positioned, and a connecting rod 28 is rotatably connected between the second support rod 12 and the fixed column 27. Both ends of the connecting rod 28 are provided with connecting holes, and the fixed column 27 passes through the connecting holes. A third rotating shaft 29 passes through the connecting holes and the through holes.

[0048] The second motor 13 drives the disc 26 to rotate. Since the fixed column 27 is eccentrically set on the disc 26, the fixed column 27 will drive the second support rod 27 to swing up and down, which makes it convenient to adjust the angle of the second support rod 12.

[0049] The scheme is further optimized. An installation plate 30 is fixedly connected to the outside of the protective cylinder 7. A rotating plate 31 is rotatably connected to the installation plate 30. Several sleeves 32 are fixedly connected to the installation plate 30. A fourth rotating shaft 33 is fixedly connected to the rotating plate 31. The fourth rotating shaft 33 passes through the sleeves 32. A third detection element 34 is fixedly connected to the rotating plate 31. A second electric telescopic rod 35 is hinged between the rotating plate 31 and the installation plate 30.

[0050] The fourth rotating shaft 33 rotates within the sleeve 32, enabling the rotating plate 31 to be rotatably connected to the mounting plate 30. The second electric telescopic rod 35 drives the rotating plate 31 to rotate, which can adjust the detection angle of the third detection element 34. The third detection element 34 is designed to prevent a detection blank area from being left between the first detection element 10 and the second detection element 14.

[0051] In a further optimized design, a fixing plate 36 is fixedly connected to the bottom surface of the substrate 2. A fifth rotating shaft 37 and a sixth rotating shaft 38 are rotatably connected to the fixing plate 36. A second gear 39 is fixedly connected to the fifth rotating shaft 37, and a third gear 40 is fixedly connected to the sixth rotating shaft 38. The second gear 39 and the third gear 40 mesh. A fourth detection element 41 is fixedly connected to the end face of the third gear 40, and a lever 42 is fixedly connected to the end face of the second gear 39.

[0052] The second gear 39 is rotated by lever 42, which drives the third gear 40 to rotate. Therefore, the detection angle of the fourth detection element 41 can be adjusted. The fourth detection element 41 is mainly used to detect the condition of the ground or the tunnel at the connection with the ground.

[0053] In a further optimized design, a third electric telescopic rod 43 is fixedly connected between the substrate 2 and the base 1. Several guide cylinders 44 are fixedly connected to the base 1, and several guide posts 45 are fixedly connected to the substrate 2. The guide posts 45 extend into the guide cylinders 44 and slide within the guide cylinders 44.

[0054] The third electric telescopic rod 43 drives the substrate 2 to move up and down, making it convenient to adjust the height of the substrate 2. The guide post 45 slides inside the guide cylinder 44, making the up and down movement of the substrate 2 more stable.

[0055] A method for detecting highway tunnels:

[0056] a. Fix the detection device to the mobile device via the support leg 3, and move the mobile device together with the detection device to one end of the tunnel;

[0057] b. Adjust the length of the first electric telescopic rod 6. The first electric telescopic rod 6 drives the first support rod 9 to move. When the first support rod 9 moves, the ball 16 rotates in the arc plate 15. The first motor 5 drives the first gear 21 to rotate. The first gear 21 drives the gear ring 20 to rotate, which can make the turntable 4 rotate. The rotation of the turntable 4 will drive the first electric telescopic rod 6 to rotate, and at the same time drive the first support rod 9 to rotate. Therefore, the detection angle of the first detection element 10 can be adjusted.

[0058] The second motor 13 drives the disc 26 to rotate. Since the fixed column 27 is eccentrically set on the disc 26, the fixed column 27 will drive the second support rod 27 to swing up and down. Therefore, the detection angle of the second detection element 14 can be adjusted so that the detection range of the second detection element 14 is different from that of the first detection element 10.

[0059] The second electric telescopic rod 35 drives the rotating plate 31 to rotate, adjusting the detection angle of the third detection element 34;

[0060] The second gear 39 is rotated by lever 42, which drives the third gear 40 to rotate. Therefore, the detection angle of the fourth detection element 41 can be adjusted. The fourth detection element 41 is mainly used to detect the condition of the ground or the tunnel at the connection with the ground.

[0061] c. The detection device is driven by a mobile device to conduct detection inside the tunnel. After exiting the tunnel, the device is turned around and driven in the opposite direction to detect different locations inside the tunnel. After exiting the tunnel again, the detection is completed. By detecting different locations inside the tunnel, tunnel defects can be detected more accurately.

[0062] d. Adjust the angle of the first support rod 9 again so that the first detection element 10 is aligned with a different detection position inside the tunnel than before. Adjust the angle of the second support rod 12 again via the second motor 13 so that the detection area of ​​the second detection element 14 is different from before. Adjust the angle of the rotating plate 31 so that the detection area of ​​the third detection element 34 is different from before. Adjust the angle of the fourth detection element 41 so that the detection area of ​​the fourth detection element 41 is different from before. Move the mobile device to drive the detection device to complete another detection inside the tunnel. Through multiple detections, the defects in the tunnel can be detected more accurately, preventing any problems from being missed.

[0063] e. Repeat the above operation to test the tunnel multiple times, and view the results from multiple tests to make the test results more accurate.

[0065] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
