[0002] Tunnel segments are the core prefabricated components in shield tunneling construction. They form the innermost barrier of the tunnel, resisting soil pressure, groundwater pressure, and other special loads. Tunnel segments are the permanent lining structure of shield tunnels, and their quality directly affects the overall quality and safety of the tunnel, influencing its waterproofing and durability.

[0003] The utility model patent CN220018397U relates to a tunnel segment inspection device, comprising a first tube body, a second tube body, and a fixing assembly. The first and second tube bodies are hollow tubes arranged in parallel. The first tube body has graduations, and the first ends of the first and second tube bodies have abutment portions. This utility model's tunnel segment inspection device can inspect segments at higher positions, eliminating the need for workers to use climbing equipment, thus improving safety. It is also convenient to operate and offers greater flexibility in use.

[0004] After the tunnel segments are produced, it is necessary to inspect the curvature and surface flatness of the tunnel segments to avoid abnormalities affecting the overall performance of the tunnel. Although the inspection device in the aforementioned patent is convenient for inspection at high altitudes, the inspection operation is relatively cumbersome and it is difficult to inspect the segments before installation, which reduces the effectiveness of tunnel segment quality inspection. Therefore, we provide a quality inspection device for tunnel segments to solve the above problems. Utility Model Content

[0006] This utility model is achieved through the following technical solution: a quality inspection device for tunnel segments.

[0007] The device includes a support base and a distance detector. The surface of the support base is provided with a support mechanism, which includes a platform and a side stop.

[0008] Preferably, a fixed frame is fixedly connected to the middle of the support base, the top of the distance detector is fixedly connected to the fixed frame, and a rotating roller is rotatably connected to the bottom of the distance detector. The rotating roller reduces the friction between the distance detector and the tunnel segment, thereby improving the stability of the tunnel segment detection.

[0009] Preferably, a support frame is fixedly connected to the surface of the support base, a sliding plate is slidably connected inside the support frame, a support slide rod is slidably connected to the middle of the platform, and the support slide rod is fixedly connected to the sliding plate.

[0010] Preferably, the surface of the platform is provided with equidistant limiting grooves, and the bottom of the side block is fixedly connected with a connecting block, which engages with the limiting groove. By inserting the connecting block into the limiting groove, the side block is fixed to the surface of the platform, thereby improving the stability of the side block's operation.

[0011] Preferably, a longitudinal groove is provided in the middle of the support base, and a limit frame is slidably connected inside the longitudinal groove. The worm wheel is rotatably connected to the limit frame, and the worm wheel is limited by the limit frame to improve the stability of the meshing between the first worm and the second worm and the worm wheel.

[0013] Preferably, a transverse sliding groove is provided in the middle of the platform, and a positioning plate is slidably connected inside the transverse sliding groove. The rotating gear is rotatably connected to the positioning plate.

[0014] This utility model provides a quality inspection device for tunnel segments, which has the following beneficial effects: This quality inspection equipment for tunnel segments uses a platform to support the tunnel segments and side stops to limit and position the segments at both ends, preventing slippage during inspection and improving the stability and accuracy of the inspection. A first and second worm gear rotate at the same speed but in opposite directions, controlling the worm wheel to rotate in place, which in turn controls the rotation of the rotating gear, causing the platform to move laterally. This allows a distance detector to inspect the current area of ​​the tunnel segment. The distance detector measures the height of the tunnel segment as the platform moves laterally. The data from the distance detector and the data from the platform's lateral movement are integrated by the equipment's processor to form an arc trajectory. Comparing this trajectory with standard data allows the equipment to determine if the tunnel segment's curvature and surface flatness are within reasonable tolerances. The first and second worm gears rotate at the same speed and in the same direction, controlling the worm wheel to move longitudinally in the middle of the support base, thus adjusting the position of the platform and the inspection area. This allows the device to perform omnidirectional inspection of the tunnel segments, improving the accuracy and convenience of the inspection.

[0015] This quality inspection equipment for tunnel segments uses a fixing frame to secure the distance detector, and rotating rollers to reduce friction between the distance detector and the tunnel segments, improving the stability of tunnel segment inspection. A support frame secures the sliding plate, and the sliding plate and support rods support and secure the platform, improving the longitudinal sliding stability of the platform and providing sufficient support to enhance the platform's positioning stability of the tunnel segments. A connecting block inserted into a limiting groove fixes the side stop block to the platform surface, improving the stability of the side stop block's movement. A limiting frame limits the worm gear, improving the stability of the meshing between the first and second worms and the worm gear, and enhancing the stability of the worm gear's movement. Rotating gears cause the linkage gear plate to move the platform laterally, improving the stability of the platform's lateral sliding. A transverse groove positions the positioning plate, and positioning the rotating gear improves the stability of the meshing between the rotating gear and the linkage gear plate.

The top of the distance detector 3 is fixedly connected to the fixing frame 2. A rotating roller 4 is rotatably connected to the bottom of the distance detector 3. The distance detector 3 is fixed by the fixing frame 2. The rotating roller 4 reduces the friction between the distance detector 3 and the tunnel segment and improves the stability of the tunnel segment detection.

[0020] Distance detector 3 is a mature technology, and this application can use existing equipment capable of detecting the height value of tunnel segments.

[0021] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The surface of the support base 1 is provided with a support mechanism 5, which includes a platform 501 and a side block 506. The platform 501 supports the tunnel segment, and the side block 506 limits and positions both ends of the tunnel segment to prevent slippage during tunnel segment inspection and improve the stability and accuracy of tunnel segment inspection.

[0022] The detection data from the distance detector 3 and the data from the lateral movement of the stage 501 are integrated by the device's processor to form an arc trajectory. By comparing the integrated trajectory with standard data, it can be determined whether the curvature and surface flatness of the tunnel segment are within a reasonable tolerance range. By rotating the first worm 601 and the second worm 602 at the same speed and in the same direction, the worm wheel 603 is controlled to move longitudinally in the middle of the support base 1, thereby adjusting the position of the stage 501 longitudinally and adjusting the tunnel segment detection area. This allows the device to perform all-round detection of the tunnel segment, improving the accuracy and convenience of tunnel segment detection.

[0023] A motor for controlling the rotation of the first worm 601 and the second worm 602 is fixedly connected to the surface of the support base 1. The motor is a mature technology, and this application can use existing equipment capable of controlling the rotation of the first worm 601 and the second worm 602.

[0024] A support frame 502 is fixedly connected to the surface of the support base 1. A sliding plate 503 is slidably connected inside the support frame 502. A support slide rod 504 is slidably connected to the middle of the platform 501, and the support slide rod 504 is fixedly connected to the sliding plate 503. The sliding plate 503 is fixed by the support frame 502. The platform 501 is supported and fixed by the sliding plate 503 and the support slide rod 504, which improves the longitudinal sliding stability of the platform 501 and provides sufficient support for the platform 501, thereby improving the stability of the platform 501 in positioning the tunnel segments.

[0025] The surface of the stage 501 is provided with equidistantly arranged limiting grooves 505. The bottom of the side block 506 is fixedly connected to a connecting block 507, and the connecting block 507 engages with the limiting grooves 505. By inserting the connecting block 507 into the limiting grooves 505, the side block 506 is fixed to the surface of the stage 501, thereby improving the stability of the side block 506 during operation.

[0026] Please refer to it again. Figure 1 , Figure 2 , Figure 4 and Figure 5 A power mechanism 6 for controlling the movement of the platform 501 is provided in the middle of the support base 1. The power mechanism 6 includes a first worm 601, a second worm 602, a worm wheel 603, and a rotating gear 606. The first worm 601 and the second worm 602 are rotatably connected to the support base 1, and the surface of the worm wheel 603 meshes with the first worm 601 and the second worm 602. By rotating the first worm 601 and the second worm 602 in opposite directions at the same speed, the worm wheel 603 is controlled to rotate in place, which in turn controls the rotating gear 606 to rotate, driving the platform 501 to move laterally, so that the distance detector 3 can detect the current area of ​​the tunnel segment. By moving the platform 501 laterally, the height value of the tunnel segment is detected by the distance detector 3.

[0027] A longitudinal groove 605 is provided in the middle of the support base 1. A limit frame 604 is slidably connected inside the longitudinal groove 605, and the worm wheel 603 is rotatably connected to the limit frame 604. The limit frame 604 is positioned by the longitudinal groove 605, and the worm wheel 603 is limited by the limit frame 604, thereby improving the stability of the meshing between the first worm 601 and the second worm 602 and the worm wheel 603, and improving the stability of the movement of the worm wheel 603.

[0028] The rotating gear 606 is located inside the stage 501 and is fixedly connected to the top of the worm gear 603. The surface of the rotating gear 606 is meshed with a linkage toothed plate 607, which is fixedly connected to the stage 501. By rotating the rotating gear 606, the linkage toothed plate 607 drives the stage 501 to move laterally, thereby improving the stability of the lateral sliding of the stage 501.

[0029] A transverse slide groove 608 is provided in the middle of the stage 501. A positioning plate 609 is slidably connected inside the transverse slide groove 608, and a rotating gear 606 is rotatably connected to the positioning plate 609. The positioning plate 609 is positioned by the transverse slide groove 608, and the stability of the meshing between the rotating gear 606 and the linkage gear plate 607 is improved by positioning the rotating gear 606.

[0030] Working principle: First, adjust the position of the side stop 506 according to the size of the tunnel segment. Then, place the tunnel segment on the surface of the platform 501. The side stop 506 positions and fixes the tunnel segment. Then, the rotating roller 4 abuts against the surface of the tunnel segment. By rotating the first worm gear 601 and the second worm gear 602 in opposite directions at the same speed, the worm wheel 603 is controlled to rotate in place, which in turn controls the rotation of the rotating gear 606, driving the platform 501 to move laterally. This allows the distance detector 3 to detect the current area of ​​the tunnel segment. By rotating the first worm gear 601 and the second worm gear 602 in the same direction at the same speed, the worm wheel 603 is controlled to rotate in place. 3. The support base 1 is moved longitudinally in the middle, thereby adjusting the position of the stage 501 longitudinally and adjusting the tunnel segment inspection area so that the device can perform all-round inspection of the tunnel segments. The height value of the tunnel segment detected by the distance detector 3 through the lateral movement of the stage 501 is sent to the processor. The processor integrates and displays the data and compares the integrated data with the standard data to determine whether the curvature and surface flatness of the tunnel segment are within the tolerance range. If the tolerance is large, it will prompt nearby staff to perform a second inspection of the current tunnel segment, thereby improving the accuracy and convenience of tunnel segment quality inspection.
