Abstract
Description
Technical Field
[0001] This application relates to the field of shield tunnel segment inspection technology, and in particular to a rapid inspection device and method for the assembly quality of long-distance shield tunnel segments. Background Technology
[0002] Currently, during the tunneling process, tunnel boring machines (TBMs) need to lay spliced tunnel segments behind them and promptly grout the gaps between the segments and the surrounding rock to increase the tunnel's strength. Due to differences in soil conditions or manual operation, problems such as segment deformation and misalignment can occur during segment laying. These deformations and misalignments, or differences in soil conditions, can lead to uneven grouting, affecting the grouting quality and consequently the tunnel's strength.
[0003] Existing technologies use laser or visual inspection instruments to detect segment splicing, and ground-penetrating radar (GPR) instruments to detect grouting quality. Since the vertical distance between the GPR instrument's base plate and the inner wall of the tunnel segment must be maintained within a certain range to ensure detection accuracy, effectively controlling this distance is crucial for improving accuracy. However, current detection technologies cannot guarantee that the distance between the GPR and the segment is within a specific range, resulting in low detection accuracy. Summary of the Invention
[0004] The purpose of this application is to provide a rapid testing device and method for the assembly quality of long-distance shield tunnel segments, so as to improve the problem of low testing accuracy caused by uneven testing distance in existing testing equipment.
[0005] Firstly, this application provides a rapid detection device for the assembly quality of long-distance shield tunnel segments, which adopts the following technical solution:
[0006] A rapid inspection device for the assembly quality of long-distance shield tunnel segments includes a track, a moving mechanism, and an inspection mechanism. The moving mechanism is located within the track and can move relative to the track, and the inspection mechanism is mounted on the moving mechanism. The inspection mechanism includes an inspection frame, a circulation component, and an inspection component. The inspection frame is mounted on the moving mechanism, the circulation component is located on the inspection frame and can move along a specific trajectory on the inspection frame, and the inspection component is mounted on the circulation component.
[0007] By adopting the above technical solution, the moving mechanism drives the detection mechanism to move on the track, so as to detect the shield tunnel segments at different positions along the track length. At the same time, the circulating component drives the detection component to move along a specific trajectory, so as to accurately detect the shield tunnel segments and improve the detection accuracy.
[0008] Optionally, the detection frame is provided with a circulation groove, which is opened according to a specific trajectory, and a rack is laid on the side wall of the circulation groove; the circulation assembly includes a circulation block, a first rotating component and a first gear, the circulation block is slidably connected to the detection frame, the first rotating component is fixedly installed on the circulation block, the output end of the first rotating component is connected to the first gear, the first gear is located in the circulation groove and meshes with the rack, and the detection assembly is connected to the circulation block.
[0009] With the above technical solution, during operation, the output end of the first rotating component rotates, driving the first gear to rotate. Through the cooperation between the first gear and the rack, the circulating block is driven to move along the trajectory of the circulating groove, thereby achieving accurate detection.
[0010] Optionally, a first telescopic member is connected to the loop block, and the movable end of the first telescopic member is connected to the detection component.
[0011] Through the above technical solution, the first telescopic component can easily change the position of the detection component in order to control the distance between the detection component and the shield tunnel segment, improve the detection accuracy, and also make it easy to adapt to shield tunnel segments of different sizes.
[0012] Optionally, a T-shaped block is connected to the circulation block, and a T-shaped groove is provided on the detection frame. The trajectory of the T-shaped groove is the same as the trajectory of the circulation groove. The T-shaped groove is set at a distance from the circulation groove, and the T-shaped block slides in the T-shaped groove.
[0013] The above technical solution, through the cooperation of the T-shaped block and the T-shaped groove, facilitates the guidance of the T-shaped block and realizes the precise movement of the circulation block.
[0014] Optionally, the moving mechanism includes a moving frame, a moving component, and a rolling component. The track includes two I-shaped monorails, each monorail having a moving groove on its side wall. The moving frame is located between the two monorails. The moving component is mounted on the moving frame. The movable end of the moving component is connected to the rolling component. The movable end of the moving component can reciprocate to allow the rolling component to enter or leave the moving groove.
[0015] Through the above technical solution, the movable end of the moving part reciprocates to allow the rolling part to enter or leave the moving groove. When inspection is required, the rolling part extends into the moving groove to drive the moving frame to move. When inspection is not required, the rolling part leaves the moving groove without affecting the practicality of the monorail.
[0016] Optionally, the moving component includes a second rotating component, a first screw, and a moving plate. The output end of the second rotating component is connected to the first screw, the first screw is threadedly connected to the moving plate, the moving plate is slidably connected to the moving frame, and the rolling component is mounted on the moving plate.
[0017] By adopting the above technical solution, the second rotating component drives the first screw to rotate, and the first screw drives the moving plate to move, thereby enabling the rolling component to enter or leave the moving groove.
[0018] Optionally, the rolling element includes a third rotating element, a roller, and a wheel. The third rotating element is mounted on a movable plate, the roller is rotatably connected to the movable plate, and the wheel is coaxially fixed with the roller.
[0019] By adopting the above technical solution, the third rotating component facilitates the rotation of the roller, which in turn drives the roller to rotate. At the same time, the roller is rotatably connected to the moving plate, so the load is mainly borne by the moving plate, reducing the impact of the load on the third rotating drive component.
[0020] Optionally, the moving plate is provided with multiple rollers, each roller is coaxially connected to a first conveyor wheel, the output end of the third rotating component is connected to a second conveyor wheel, and the multiple first conveyor wheels and one second conveyor wheel are connected to the same conveyor belt.
[0021] The above technical solution improves the synchronicity and stability of movement by using the same conveyor belt to drive multiple rollers to move simultaneously.
[0022] Optionally, a storage rod is hinged to the movable frame, and the end of the storage rod away from the movable frame is connected to the detection mechanism.

The output end of the fourth rotating component is connected to the second screw. A helical seat is threaded onto the second screw, and a connecting rod is hinged to the helical seat. The end of the connecting rod away from the helical seat is hinged to the storage rod. A second telescopic component is connected to the end of the storage rod away from the movable frame, and the movable end of the second telescopic component is connected to the detection mechanism.
[0023] By adopting the above technical solution, the fourth rotating component can easily drive the second screw to rotate, and the second screw can drive the screw seat to move, which in turn drives the storage rod to swing through the connecting rod, making it easy to open or close the storage rod. When the detection device needs to perform detection, the storage rod is opened; when the detection device does not need to perform detection, the storage rod is closed, reducing the space occupied by the detection component and reducing the impact on other construction facilities.
[0024] A detection method, based on the aforementioned rapid detection device for the assembly quality of long-distance shield tunnel segments, is characterized by comprising the following steps:
[0025] S1. The detection component is driven by the circulation component to move along a specific trajectory to detect the shield tunnel segment at the location of the moving component;
[0026] S2. After the current position detection is completed, the moving component moves to a new position, and the looping component drives the detection component to detect the shield tunnel segment at the current position of the moving component.
[0027] S3. Repeat steps S1 and S2 until all tunnel segments have been inspected.
[0028] In summary, this application includes at least one of the following beneficial technical effects:
[0029] 1. The moving mechanism drives the detection mechanism to move on the track to detect the shield tunnel segments at different positions along the track length. At the same time, the circulating component drives the detection component to move along a specific trajectory to accurately detect the shield tunnel segments and improve the accuracy of the detection.
[0030] 2. During operation, the output end of the first rotating component rotates, driving the first gear to rotate. Through the cooperation of the first gear and the rack, the circulating block is driven to move along the trajectory of the circulating groove, thereby achieving accurate detection.
[0031] 3. The first telescopic component facilitates changing the position of the detection component in order to control the distance between the detection component and the shield tunnel segment, improve detection accuracy, and also facilitates adaptation to shield tunnel segments of different sizes;
[0032] 4. The movable end of the moving part reciprocates to allow the rolling part to enter or leave the moving groove.

[0033] 5. The third rotating component facilitates the rotation of the roller, which in turn drives the roller to rotate. At the same time, the roller is rotatably connected to the moving plate, so the load is mainly borne by the moving plate, reducing the impact of the load on the third rotating drive component.
[0034] 6. The fourth rotating component facilitates the rotation of the second screw, which in turn drives the screw seat to move, thereby causing the storage rod to swing through the connecting rod.

[0042] Example 1
[0043] Firstly, this application discloses a rapid testing device for the assembly quality of long-distance shield tunnel segments.
[0044] A rapid testing device for the assembly quality of long-distance shield tunnel segments, referring to Figures 1 to 4 It includes a track, a moving mechanism 2 and a detection mechanism 3. The moving mechanism 2 is located inside the track and can move relative to the track. The detection mechanism 3 is installed on the moving mechanism 2.
[0045] Specifically, the moving mechanism 2 includes a moving frame 21, a moving component 22, and a rolling component 23. The track includes two I-shaped monorails 1, each monorail 1 having a moving groove 11 on its side wall. The moving frame 21 is located between the two monorails 1. The moving component 22 is mounted on the moving frame 21, and its movable end is connected to the rolling component 23. The movable end of the moving component 22 can reciprocate, allowing the rolling component 23 to enter or leave the moving groove 11. During operation, the movable end of the moving component 22 reciprocates, allowing the rolling component 23 to enter or leave the moving groove 11. When inspection is required, the rolling component 23 extends into the moving groove 11 to move the moving frame 21. When inspection is not required, the rolling component 23 disengages from the moving groove 11 without affecting the usability of the monorail 1.
[0046] It should be noted that four electric cylinders are fixedly installed at the bottom of the movable frame 21. When the movable rods of the four electric cylinders extend, the movable frame 21 is supported by the four electric cylinders; when the movable rods of the four electric cylinders retract, the movable frame 21 is supported by the rolling element 23.
[0047] The inspection mechanism 3 includes an inspection frame 31, a circulation component 32, and an inspection component 33. The inspection frame 31 is mounted on the moving mechanism 2. The circulation component 32 is located on the inspection frame 31 and can move along a specific trajectory on the inspection frame 31. The inspection component 33 is mounted on the circulation component 32. During inspection, the moving mechanism 2 drives the inspection mechanism 3 to move along the track to inspect the tunnel segments at different positions along the track length. At the same time, the circulation component 32 drives the inspection component 33 to move along the specific trajectory to accurately inspect the tunnel segments and improve the accuracy of the inspection.
[0048] Specifically, the detection frame 31 is provided with a circulation groove 311, which is opened according to a specific trajectory. The specific trajectory can be the cross-sectional shape of the tunnel, such as circular or arched. At the same time, the bottom of the tunnel is inspected before the track is laid. Therefore, the detection component 33 mainly inspects the sidewalls and top of the tunnel, and the specific trajectory only needs to be the same as the shape of the sidewalls and top of the tunnel cross-section. The circulation component 32 includes a circulation block 321, a first rotating member 322, and a first gear 323. The circulation block 321 is slidably connected to the detection frame 31, and the first rotating member 322 is fixedly installed on the circulation block 321. The output end of the first rotating member 322 is connected to the first gear 323. A rack 324 is laid on the sidewall of the circulation groove 311. The first gear 323 is located in the circulation groove 311 and meshes with the rack 324. The detection component 33 is connected to the circulation block 321. During operation, the output end of the first rotating component 322 rotates, driving the first gear 323 to rotate. Through the cooperation of the first gear 323 and the rack 324, the circulation block 321 is driven to move along the trajectory of the circulation groove 311, thereby achieving accurate detection.
[0049] It should be noted that a T-shaped block 325 is connected to the circulation block 321, and a T-shaped groove 312 is provided on the detection frame 31. The trajectory of the T-shaped groove 312 is the same as the trajectory of the circulation groove 311. The T-shaped groove is set at a distance from the circulation groove 311. The T-shaped block 325 slides within the T-shaped groove 312 and is adapted to the T-shaped groove 312. Through the cooperation between the T-shaped block 325 and the T-shaped groove 312, the T-shaped block 325 is easily guided, realizing the precise movement of the circulation block 321.
[0050] More specifically, a first telescopic member 326 is connected to the circulation block 321, and the movable end of the first telescopic member 326 is connected to the detection component 33. In the initial position, the first telescopic member 326 is set horizontally, which facilitates changing the position of the detection component 33 in the horizontal direction, so as to control the distance between the detection component 33 and the shield tunnel segment, improve the detection accuracy, and also facilitate the adaptation to shield tunnel segments of different sizes.
[0051] Optionally, a storage rod 24 is hinged to the movable frame 21. A second telescopic member 241 is connected to the end of the storage rod 24 away from the movable frame 21. The output end of the second telescopic member 241 is connected to the detection frame 31 of the detection mechanism 3. The position of the detection frame 31 can be adjusted vertically via the second telescopic member 241 to cooperate with the first telescopic member 326 and adjust the position of the detection component 33 on the tunnel cross-section, thereby achieving precise detection and improving detection accuracy.
[0052] A second screw 251 is rotatably connected to the movable frame 21. A fourth rotating component 25 is also fixedly installed on the movable frame 21. The output end of the fourth rotating component 25 is connected to the second screw 251. A screw seat 252 is threaded onto the second screw 251, and a connecting rod 253 is hinged to the screw seat 252. The end of the connecting rod 253 away from the screw seat 252 is hinged to the storage rod 24. The fourth rotating component 25 facilitates the rotation of the second screw 251, which in turn drives the screw seat 252 to move. This, in turn, causes the storage rod 24 to swing via the connecting rod 253, facilitating the opening or closing of the storage rod 24. When the detection device is required for testing, the storage rod 24 is opened; when the detection device is not required, the storage rod 24 is closed, reducing the space occupied by the detection component 33 and minimizing its impact on other construction facilities. The output end of the fourth rotating component 25 and the second screw 251 can be driven by a belt drive.
[0053] Furthermore, the movable frame 21 is provided with two sets of movable components 22. Each set of movable components 22 includes a second rotating component 221, a first screw 222, and a movable plate 223. The output end of the second rotating component 221 is connected to the first screw 222. The first screw 222 is threadedly connected to the movable plate 223. The movable plate 223 is slidably connected to the movable frame 21. The rolling component 23 is mounted on the movable plate 223. The second rotating component 221 drives the first screw 222 to rotate, and the first screw 222 drives the movable plate 223 to move, thereby allowing the rolling component 23 to enter or leave the movable groove 11. In this embodiment, both the second rotating component 221 and the first screw 222 are provided with two sets.
[0054] Specifically, the rolling element 23 includes a third rotating element 231, a roller 232, and a roller 233. The third rotating element 231 is mounted on the movable plate 223. The roller 232 is rotatably connected to the movable plate 223. The roller 233 is coaxially fixed to the roller 232. The third rotating element 231 facilitates the rotation of the roller 232, which in turn drives the roller 233 to rotate. At the same time, the roller 232 is rotatably connected to the movable plate 223, so the load is mainly borne by the movable plate 223, reducing the impact of the load on the third rotating driving element.
[0055] It should be noted that the moving plate 223 is equipped with multiple rollers 232, each roller 232 is coaxially connected to a first conveyor wheel 26, and the output end of the third rotating component 231 is connected to a second conveyor wheel 262. The multiple first conveyor wheels 26 and one second conveyor wheel 262 are connected to the same conveyor belt 263. The same conveyor belt 263 drives multiple rollers 232 to move simultaneously, improving the synchronization and stability of the movement. The conveyor belt 263 can be a chain or a timing belt, and the conveyor wheels can be sprockets or timing pulleys.
[0056] In addition, the detection component 33 can be a laser detector, a visual detector, or a ground-penetrating radar detector, etc. The first rotating component 322, the second rotating component 221, the third rotating component 231, and the fourth rotating component 25 can all be motors, and the first telescopic component 326 and the second telescopic component 241 can both be electric cylinders.
[0057] Firstly, this application discloses a detection method.
[0058] A detection method, based on the aforementioned rapid detection device for the assembly quality of long-distance shield tunnel segments, is characterized by comprising the following steps:
[0059] S1. The detection component 33 is moved along a specific trajectory by the circulation component 32 to detect the shield tunnel segment at the location of the moving component;
[0060] S2. After the current position detection is completed, the moving component moves to a new position, and the loop component 32 drives the detection component 33 to detect the shield tunnel segment at the current position of the moving component.
[0061] S3. Repeat steps S1 and S2 until all tunnel segments have been inspected.
