Description

Technical Field

[0001] This utility model relates to the technical field of tunnel quality inspection, specifically a road bridge tunnel lining inspection device. Background Technology

[0002] During tunnel construction, the inner walls of the tunnel need to be lined with concrete. Tunnel lining is a permanent support structure built around the tunnel body using reinforced concrete and other materials to prevent deformation or collapse of the surrounding rock. Different lining forms can be adopted according to the working environment and requirements. After the tunnel lining is completed, the quality of the tunnel lining needs to be tested. The tunnel lining must have sufficient strength, durability and erosion resistance to ensure that the lined tunnel meets the relevant requirements and ensures the safety of traffic in the future.

[0003] Utility model patent CN221550061U discloses a road bridge tunnel lining testing device, belonging to the technical field of tunnel quality testing. It addresses the problem that in existing technologies, tunnel lining sampling and testing often involves workers holding the sampling device and drilling into the tunnel wall. This process is particularly problematic when sampling curved tunnel arches, where the angle is difficult to maintain for extended periods, leading to swaying and high workload, which also affects the sampling results. The device includes a base with multiple casters at the bottom and vertical supports at both ends. The device has side plates, and a mounting block is rotatably mounted between the two side plates via a pivot. A limiting component restricts the rotation of the pivot on the side wall of each side plate. Multiple mounting columns are fixedly mounted on the side wall of each mounting block. A mounting plate is mounted on the end of each mounting column furthest from the mounting block, and a through hole is provided on the mounting plate. A first motor is fixedly mounted between the mounting plate and the mounting block via a drive assembly. A sampling cylinder is detachably mounted on the output end of the first motor. The drive assembly is used to drive the sampling cylinder to move along the length of the mounting column. This design solves the problem in the prior art where the sampling equipment is unstable and affects the sampling results when workers sample and test the curved surface of the tunnel lining.

[0004] However, the above patent still has shortcomings: although the patent can sample and test the arched surface of the tunnel lining, it does not have the function of adjusting the overall height of the device. Due to the uneven height inside the arched surface of the tunnel, the device is inconvenient to sample and test at higher parts of the tunnel because the overall height of the device is insufficient.

This facilitates sampling at higher points in the tunnel and solves the problem that while existing road and bridge tunnel lining testing devices can sample and test the arched surface of tunnel lining, they do not have the function of adjusting the overall height of the device. Due to the varying heights inside the arched surface of the tunnel, the device is inconvenient to sample at higher points in the tunnel because of insufficient overall height.

[0016] Secondly, this utility model improves the accuracy of the device's adjustment based on the curvature of the tunnel's interior by utilizing the combined action of the base frame, lifting frame, platform, support plate, adjusting block, support rod, rectangular plate, partition, and self-locking mechanism. Furthermore, it can lock the adjusted device to prevent angle changes. This solves the problem of existing road, bridge, and tunnel lining inspection devices that rely on gears and inserts to achieve angle adjustment and self-locking, but which suffer from significant errors due to gaps in the gear-insert-insert-gear fit when adjusting the angle based on the tunnel's interior curvature.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 The present invention will describe the above technical solution in detail through the following embodiments:

[0027] A road, bridge, and tunnel lining inspection device includes: a base frame 1; a lifting frame 2 is provided on the top of the base frame 1, a platform 3 is fixedly connected to the top of the lifting frame 2, two support plates 4 are fixedly connected to the top of the lifting frame 2, an adjusting block 5 is provided between the two support plates 4, support rods 6 are fixedly connected to the four corners of the top of the adjusting block 5, and the tops of the support rods 6 are fixedly connected to rectangular plates 7; a partition 8 is fixedly connected inside the base frame 1; a lifting mechanism 9 for adjusting the overall height of the device is provided on one side of the partition 8; and a device for raising the drilling angle is provided on both sides of the adjusting block 5. The device features a high-precision self-locking mechanism 10. A control box with an internal battery is located on one side of the top of the platform 3. The battery not only provides power to the device but can also be connected to a power source via wires, improving the device's flexibility. The user moves the device into the tunnel and then controls the lifting frame 2 to rise via the lifting mechanism 9. As the lifting frame 2 rises, it also moves the platform 3, thereby adjusting the overall height of the device according to the height of the sampling point inside the tunnel. The self-locking mechanism 10 then controls the device to adjust the sampling angle according to the curved surface inside the tunnel, allowing for sampling.

[0028] like Figure 4As shown, the lifting mechanism 9 includes: a first moving rod 11 is provided on one side of the partition 8, the first moving rod 11 is slidably connected to the bottom frame 1, and scissor telescopic rods 12 are rotatably connected to both ends of the first moving rod 11. The sides of the two scissor telescopic rods 12 away from the first moving rod 11 are fixedly connected by a first rotating rod 13. Two first fixing blocks 14 are rotatably connected to the outer surface of the first rotating rod 13 near the bottom frame 1, and the first fixing blocks 14 are all fixedly connected to the bottom frame 1; the top sides of the two scissor telescopic rods 12 are fixedly connected to a second moving rod 15, the second moving rod 15 is slidably connected to the lifting frame 2, and the sides of the two scissor telescopic rods 12 away from the second moving rod 15 are fixedly connected by a second rotating rod 16. Two second fixing blocks 16 are rotatably connected to the outer surface of the second rotating rod 16 near the lifting frame 2. Block 17 and the second fixed block 17 are both fixedly connected to the lifting frame 2; a power mechanism 18 is provided in the middle of the first moving rod 11 to control the horizontal movement of the first moving rod 11. The user controls the first moving rod 11 to move horizontally inside the bottom frame 1 through the power mechanism 18. While the first moving rod 11 moves, it drives one side of the bottom of the two scissor telescopic rods 12. The two scissor telescopic rods 12 drive the first rotating rod 13. The first rotating rod 13 rotates inside the first fixed block 14, thereby causing the overall height of the two scissor telescopic rods 12 to increase at a uniform speed. While the height of the two scissor telescopic rods 12 increases, it drives the second moving rod 15. The second moving rod 15 drives the lifting frame 2 to rise horizontally at a uniform speed through the cooperation of the second rotating rod 16 and the second fixed block 17, thereby achieving the purpose of adjusting the height of the device.

[0029] like Figure 4 and Figure 5 As shown, the power mechanism 18 includes: a threaded block 19 fixedly connected to the middle of the first moving rod 11, and a screw 20 threadedly connected to the inside of the threaded block 19; one end of the screw 20 is rotatably connected to the bottom frame 1, and the other end of the screw 20 passes through the partition 8 and extends to the first motor 21; the first motor 21 is fixedly connected to the partition 8; the screw 20 is fixedly connected to the output end of the first motor 21; when the first motor 21 is started, the output end of the first motor 21 drives the screw 20; the screw 20 rotates through the cooperation between the partition 8 and the bottom frame 1; while the screw 20 rotates, it drives the threaded block 19; the threaded block 19 drives the first moving rod 11 to move horizontally and uniformly inside the bottom frame 1.

[0030] like Figure 3As shown, the outer surfaces of both ends of the first moving rod 11 and the second moving rod 15 are rotatably connected to limit sliders 22. The bottom frame 1 and the lifting frame 2 are provided with matching grooves 23 near the limit sliders 22. The limit sliders 22 are slidably connected to the grooves 23 respectively. This not only limits the first moving rod 11 and the second moving rod 15 so that the first moving rod 11 and the second moving rod 15 can slide horizontally, but also allows the first moving rod 11 and the second moving rod 15 to rotate without affecting their rotation.

[0031] like Figure 6 As shown, the self-locking mechanism 10 includes: first rotating shafts 24 fixedly connected to both sides of the adjusting block 5, one end of the first rotating shaft 24 away from the adjusting block 5 being rotatably connected to the support plate 4, and the other end of the first rotating shaft 24 away from the adjusting block 5 penetrating the support plate 4 and extending to the protective box 25. The first rotating shafts 24 are rotatably connected to the protective box 25, and the protective box 25 is fixedly connected to the support plate 4. A worm gear 26 is fixedly connected to the outer surface of the first rotating shaft 24 located inside the protective box 25. A worm 27 is meshed at the bottom of the worm gear 26. One end of the worm 27 is rotatably connected to the protective box 25, and the other end of the worm 27 penetrates the support plate 4. The device passes through the protective box 25 and extends to the second motor 28. The second motor 28 is fixedly connected to the protective box 25. The worm gear 27 is fixedly connected to the output end of the second motor 28. When the second motor 28 is started, the output end of the second motor 28 drives the worm gear 27. The worm gear 27 rotates with the cooperation of the protective box 25. While rotating, the worm gear 27 drives the worm wheel 26. The worm wheel 26 drives the first rotating shaft 24. The first rotating shaft 24 rotates with the cooperation of the support plate 4. While rotating, the first rotating shaft 24 drives the adjusting block 5. The adjusting block 5 drives the support rod 6 and the rectangular plate 7, thereby adjusting the sampling angle of the device.

[0032] like Figure 6 As shown, a hydraulic cylinder 29 is installed inside the adjusting block 5. A third motor 30 is fixedly connected to the telescopic end of the hydraulic cylinder 29. A sampling cylinder 31 is fixedly connected to the output end of the third motor 30. The top of the sampling cylinder 31 passes through the rectangular plate 7 and extends to the outside of the rectangular plate 7. A dust cover 32 is fixedly connected to the rectangular plate 7 near the sampling cylinder 31. The dust cover 32 cooperates with the sampling cylinder 31. When the third motor 30 is started, the output end of the third motor 30 drives the sampling cylinder 31 to rotate. Then, the hydraulic cylinder 29 is started. The telescopic end of the hydraulic cylinder 29 extends outward and pushes the third motor 30. The third motor 30 pushes the sampling cylinder 31, thereby causing the sampling cylinder 31 to take a sample.

[0033] like Figure 1As shown, each of the four bottom corners of the bottom frame 1 is fixedly connected to a connecting block 33. Each connecting block 33 is equipped with a universal wheel 34 with a braking function at its bottom. The universal wheel 34 is fixedly connected to the connecting block 33, making it convenient for the user to move and fix the device.

[0034] Working principle: The user moves the device into the tunnel and then starts the first motor 21. The output of the first motor 21 drives the screw 20. The screw 20 rotates through the cooperation of the partition 8 and the bottom frame 1. Simultaneously, the rotation of the screw 20 drives the threaded block 19, which in turn drives the first moving rod 11 to move horizontally and uniformly inside the bottom frame 1. The movement of the first moving rod 11 also drives one side of the bottom of the two scissor telescopic rods 12. The two scissor telescopic rods 12 drive the first rotating rod 13, which rotates within the first fixed block 14. This causes the overall height of the two scissor telescopic rods 12 to increase uniformly. Simultaneously, the second moving rod 15 is driven, and the second moving rod 15, through the cooperation of the second rotating rod 16 and the second fixed block 17, drives the lifting frame 2 to rise horizontally at a uniform speed, thereby achieving the purpose of adjusting the height of the device. The overall height of the device can be adjusted according to the height of the tunnel sampling point, making it convenient for the device to sample higher parts of the tunnel. This solves the problem that although the existing road bridge tunnel lining detection device can sample and detect the arc-shaped arch surface of the tunnel lining, it does not have the function of adjusting the overall height of the device. Due to the uneven height inside the arc-shaped arch surface of the tunnel, the device is inconvenient to sample when detecting higher parts of the tunnel because the overall height of the device is insufficient.

[0035] The second motor 28 is started, and its output drives the worm gear 27. The worm gear 27 rotates with the help of the protective box 25. While rotating, the worm gear 27 drives the worm wheel 26, which in turn drives the first shaft 24. The first shaft 24 rotates with the help of the support plate 4, and simultaneously drives the adjusting block 5. The adjusting block 5 drives the support rod 6 and the rectangular plate 7, thereby adjusting the sampling angle of the device. This improves the accuracy of the device in adjusting according to the curvature of the inside of the arched tunnel and allows for locking the adjusted device to prevent angle changes. This solves the problem of existing road bridge tunnel lining detection devices that use gears and inserts to achieve angle adjustment and self-locking, but the gap between the inserts and gears causes a large error when adjusting the angle according to the curvature of the tunnel.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
