Description

Technical Field

[0001] The utility model relates to the technical field of tunnel lining quality detection, and more specifically, to a tunnel lining quality detection bracket. Background Art

[0002] In current technical applications, tunnel lining quality inspection brackets face a series of challenges, especially in adapting to the complex and irregular geometry of the tunnel interior. Tunnel linings are usually composed of curved surfaces that are neither parallel nor have standard geometries. This irregularity requires the inspection bracket to have a high degree of flexibility and adjustment capabilities to ensure effective inspection on these complex surfaces.

[0003] First, the existing tunnel lining quality inspection bracket has limitations in terms of adjustment. To accurately measure the quality indicators of the lining (such as thickness, density and crack width, etc.), the inspection device must be able to maintain an appropriate distance and angle with the lining surface. However, due to the non-parallel curved surfaces inside the tunnel, if the bracket and device cannot be finely adjusted in three dimensions, effective contact with the lining surface may not be achieved, thereby reducing the accuracy and reliability of the inspection effect.

[0004] Secondly, regarding the problem of sensor fixation, existing technologies have not provided a convenient and quick solution. An effective fixation mechanism is essential to ensure the stability of the sensor during the detection process. Stable fixation not only affects the accuracy of the detection data, but is also directly related to the detection efficiency and operational convenience. When conducting quality inspections on irregular tunnel lining surfaces, if the sensors cannot be adjusted and fixed quickly and reliably, the inspection process may be slow and cumbersome, and even inaccurate data collection may occur.

The thrust bearing 6 The two ends respectively abut against the receiving sleeve 7 and the compression spring 8, the compression spring 8 is installed on the insertion tube 9, the insertion tube 9 is slidably connected to the fixed sleeve 3, the hexagonal sleeve 10 is installed on the insertion tube 9, and the hexagonal sleeve 10 is threadedly connected to the fixed sleeve 3, the clamping mechanism includes a clamping spring 11 and a mounting rod 12, a plurality of clamping springs 11 are provided, and the two ends of each clamping spring 11 are respectively connected to the mounting rod 12, the clamping spring 11 abuts against the side wall of the touch sensor, a plurality of clamping blocks 5 are provided, and each clamping block 5 is respectively provided with a plurality of mounting holes 13, the mounting rod 12 is connected in the mounting hole 13, and a limit plate 14 is coaxially provided on the fixed sleeve 3, and the limit plate 14 is fitted on the adjustment seat 2.

[0031] In this embodiment, when the sensor needs to be fixed, first connect the mounting rod 12 to the mounting hole 13, so that multiple clamping blocks 5 are respectively connected to the clamping blocks 5, and then insert the sensor between multiple retaining springs 11. Rotating the hexagonal sleeve 10 can drive the insertion rod to move downward, and then drive the compression spring 8 to contact the thrust bearing 6, and then press on the clamping block 5 through the receiving sleeve 7. The clamping block 5 will shrink toward the axial direction along with the expansion block 4, so the sensor can be fixed by multiple retaining springs 11, thereby ensuring the fixing stability of the sensor.

[0032] See also Figure 1 and Figure 2 As an implementation method of the telescopic mechanism: the telescopic mechanism includes a rotating sleeve 15, an extending block 16 and a folding plate 17, the rotating sleeve 15 is rotatably connected to the support rod 1, the extending block 16 is installed on the side wall of the rotating sleeve 15, the folding plate 17 is attached to the extending block 16, and a follower block 18 is provided on the adjusting seat 2 for matching connection, the follower block 18 is attached to the folding plate 17, a follower sleeve 19 and a friction plate 20 are slidably provided on the folding plate 17, the two ends of the friction plate 20 are respectively connected to the follower sleeve 19, the friction plate 20 is attached to the inner walls of the extending block 16, the folding plate 17 and the follower block 18, a bolt 21 is slidably provided in the follower sleeve 19, a nut 22 is threaded on the bolt 21, and the nut 22 and the bolt 21 are respectively attached to the follower sleeve 19 at both ends.

[0033] More specifically, since the sensor is connected to the adjustment seat 2, when it is necessary to adjust the rotation force of the protruding block 16, the folding plate 17 and the follower block 18, the two follower sleeves 19 can be clamped by first rotating the nut 22 and the bolt 21, so that the friction plate 20 expands outward and then presses against the inner walls of the protruding block 16, the folding plate 17 and the follower block 18. As the force of the bolt 21 increases, the fixing force increases, thereby completing the force process. Therefore, the corresponding force can be adjusted according to the situation to adapt to the detection requirements in the tunnel, and then the lining is detected by the sensor, thereby completing the corresponding process.

[0034] In summary, when the overall device is in use or running: when the sensor needs to be fixed, first connect the mounting rod 12 to the mounting hole 13, so that multiple clamping blocks 5 are respectively connected to the clamping blocks 5, and then insert the sensor between the multiple clamping springs 11, and rotate the hexagonal sleeve 10 to drive the insertion rod to move downward, and then drive the compression spring 8 to contact the thrust bearing 6, and then press on the clamping block 5 through the receiving sleeve 7. The clamping block 5 will shrink toward the axial direction with the expansion block 4, so the sensor can be fixed by multiple clamping springs 11, thereby ensuring the fixing stability of the sensor.

[0035] Since the sensor is connected to the adjustment seat 2, when it is necessary to adjust the rotation force of the protruding block 16, the folding plate 17 and the follower block 18, the two follower sleeves 19 can be clamped by first rotating the nut 22 and the bolt 21, so that the friction plate 20 expands outward and then presses against the inner walls of the protruding block 16, the folding plate 17 and the follower block 18. As the force of the bolt 21 increases, the fixing force increases, thereby completing the force process. Therefore, the corresponding force can be adjusted according to the situation to adapt to the detection requirements in the tunnel, and then the lining is detected by the sensor, thereby completing the corresponding process.

[0036] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
