Description

Technical Field

[0001] This utility model relates to the field of antenna adjustment technology, and in particular to a 90° rotation device for the ranging wheel of a 900M ground-penetrating radar antenna. Background Technology

[0002] With the continuous expansion of tunnel engineering scale and the increasing demands for operational safety, ground-penetrating radar (GPR) technology is being used more and more widely in the non-destructive testing of tunnel linings. Among these, the 900MHz frequency antenna, due to its moderate penetration depth and high imaging resolution, has become one of the commonly used configurations in GPR testing. GPR relies on a ranging wheel in conjunction with an antenna system to scan and analyze anomalies within the lining structure. Its detection accuracy and operational flexibility directly affect the accuracy of anomaly identification and the efficiency of detection.

[0003] In existing technologies, a ranging wheel is typically fixed below the antenna body, and data is collected by moving in a straight line at a constant speed. However, in actual tunnel inspection sites, due to structural space constraints, terrain undulations, or antenna layout requirements, it is necessary to temporarily rotate the antenna 90° to move laterally to improve the resolution of signals from the lining interface. In this case, traditional ranging wheel systems cannot flexibly adjust with changes in antenna angle, requiring manual disassembly, reinstallation, and parameter resetting of the instrument, which is cumbersome and inefficient. Therefore, existing technologies lack a structure that can easily achieve rapid switching of the relative angle between the antenna and the ranging wheel, especially one that ensures installation stability while possessing rapid locking and turning functions to adapt to the data acquisition needs of tunnel inspection in different directions. Therefore, a 90° rotation device for the ranging wheel of a 900M ground-penetrating radar antenna is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a 90° rotation device for the ranging wheel of a 900M ground-penetrating radar antenna. It aims to improve the problem that the ranging wheel in traditional devices cannot be adjusted 90° synchronously with the antenna, resulting in angle deviation, large positioning error and low work efficiency during the detection process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a 900M ground-penetrating radar antenna ranging wheel 90° rotation device, including an antenna body, a bracket is provided on one side of the antenna body, a ranging wheel body is provided on one side of the outer wall of the bracket, and an adjustment component is installed between the antenna body and the bracket;

[0006] The adjustment assembly includes a sleeve, a mounting bracket, a mounting plate, and an arc-shaped groove. The outer wall of the mounting bracket is rotatably connected to the inner wall of the support. One end of the sleeve is fixedly connected to the inner wall of the mounting bracket. The mounting plate is disposed on the upper side of the mounting bracket. The arc-shaped groove is formed inside the mounting plate. One side of the lower surface of the mounting plate is fixedly connected to the upper surface of the antenna body. A fastening assembly is installed inside the mounting plate.

[0007] Furthermore, the fastening assembly includes two adjusting bolts and an adjusting nut. One adjusting bolt passes through the mounting bracket and the mounting plate and is fixed by one adjusting nut. The other adjusting bolt passes through the mounting bracket and is slidably connected to the inner wall of the arc-shaped groove. The inner wall of the other adjusting nut is threadedly connected to the outer wall of the other adjusting bolt.

[0008] Furthermore, the mounting plate is threadedly connected to the inside of the antenna body via an adjusting bolt, and an abutment plate is fixedly connected to the lower surface of the mounting plate.

[0009] Furthermore, a mounting bolt is provided through the inside of the sleeve, and a mounting nut is threaded onto the outer wall of the mounting bolt.

[0010] Furthermore, one end of the mounting bolt abuts against one side of the outer wall of the bracket, and one side of the mounting nut abuts against the other side of the outer wall of the bracket.

[0011] Furthermore, an abutment plate is fixedly connected to the lower surface of the mounting plate, and one side of the outer wall of the abutment plate is fixedly connected to one side of the outer wall of the antenna body.

[0012] Furthermore, an adjusting bolt is provided through the inside of the mounting plate, and the outer wall of the adjusting bolt is threadedly connected to the inside of the antenna body.

[0013] Furthermore, the upper surface of the mounting bracket is rotatably connected to the lower surface of the mounting plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by rotating the mounting bracket, the fastening component limits the position of the mounting bracket inside the arc groove, thereby achieving the effect of quickly adjusting the ranging wheel body by 90°. This solves the problem that the traditional ranging wheel body needs to be removed and reinstalled during the adjustment process, thus improving the practicality of the antenna.

[0016] 2. In this utility model, the combination of adjusting bolt two and adjusting nut can achieve the effect of quickly positioning the angle of the measuring wheel body. At the same time, the combination of mounting bolt and mounting nut can facilitate the adjustment of the bracket angle to further adjust the measuring wheel body, thereby improving the accurate positioning of abnormal objects, saving working time and improving work efficiency.

[0024] 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.

[0025] Reference Figures 1-5This utility model provides an embodiment of a 900M ground-penetrating radar antenna ranging wheel 90° rotation device, including an antenna body 1, a support 2 on one side of the antenna body 1, and a ranging wheel body 4 on one side of the outer wall of the support 2. The ranging wheel body 4 rotates to achieve stable antenna movement testing. An adjustment component is installed between the antenna body 1 and the support 2 to realize the angle adjustment function between the antenna and the ranging wheel; the adjustment component includes a sleeve 5, a mounting frame 6, a mounting plate 9, and an arc groove 11. The outer wall of the mounting frame 6 is rotatably connected to the inner wall of the support 2, so that the mounting frame 6 can rotate 90° around its rotation axis; one end of the sleeve 5 is fixedly connected to the inner wall of the mounting frame 6, providing connection and support; the mounting plate 9 is set on the upper side of the mounting frame 6 for connecting the antenna body 1; the arc groove 11 is opened inside the mounting plate 9 as a trajectory channel for the adjustment bolt to limit the movement. The mounting plate 9 is fixedly connected to the upper surface of the antenna body 1 on one side of its lower surface to ensure the overall structural rigidity and transmission stability. The mounting plate 9 has a fastening assembly installed inside for adjusting and locking the angle of the device. The fastening assembly includes two adjusting bolts 13 and an adjusting nut 3. One adjusting bolt 13 passes through the mounting bracket 6 and the mounting plate 9 and is fixed by an adjusting nut 3 to fasten and limit the initial connection structure. The other adjusting bolt 13 passes through the mounting bracket 6 and is slidably connected to the inner wall of the arc groove 11 to provide a movement trajectory for adjusting the angle. The inner wall of the other adjusting nut 3 is threaded to the outer wall of the adjusting bolt 13 to lock the adjustment position and ensure the stability of the structure after adjustment.

[0026] Specifically, through the combination of the above structures, the function of quick angle adjustment between the ranging wheel body 4 and the antenna body 1 is realized. The operator can achieve positioning at any angle within a 90° range by adjusting the bolt in the arc groove 11, and lock the target angle by adjusting the nut 3. Horizontal or longitudinal movement detection can be achieved without disassembling the ranging wheel, thereby improving the adaptability and ease of use of the ground-penetrating radar in complex tunnel environments.

[0027] Reference Figures 1-5The mounting plate 9 is threadedly connected to the antenna body 1 via adjusting bolt 12, which securely mounts the mounting plate 9 onto the antenna body 1, ensuring its stability. A contact plate 10 is fixedly connected to the lower surface of the mounting plate 9. The contact plate 10 provides a load-bearing contact surface for the antenna body 1 during angle adjustment, improving the overall structure's resistance to deformation and connection strength. A mounting bolt 7 is threaded through the inside of the sleeve 5, connecting the bracket 2 and the sleeve 5, providing a detachable connection structure. A mounting nut 8 is threaded onto the outer wall of the mounting bolt 7, securing the end of the mounting bolt 7. One end of the mounting bolt 7 abuts against one side of the outer wall of the bracket 2, and one side of the outer wall of the mounting nut 8 abuts against the other side of the outer wall of the bracket 2, clamping and fixing the sleeve 5 and the bracket 2, ensuring a stable connection under stress and preventing loosening. The contact plate 10 is fixedly connected to the lower surface of the mounting plate 9, with one side of its outer wall fixedly connected to one side of the outer wall of the antenna body 1, further enhancing the fit between the antenna body 1 and the mounting plate 9. An adjusting bolt 12 is installed through the interior of the mounting plate 9. The outer wall of the adjusting bolt 12 is threaded into the interior of the antenna body 1, providing the ability to adjust the height or angle of the mounting plate 9, thus enabling fine-tuning of the overall assembly position. The upper surface of the mounting bracket 6 is rotatably connected to the lower surface of the mounting plate 9, ensuring that the mounting bracket 6 can be rotated and adjusted relative to the mounting plate 9 within a certain angular range.

[0028] Specifically, through the combination of the above structures, while connecting the antenna body 1 and the ranging wheel body 4, a reliable limiting and adjustment interface is constructed through the adjusting bolt 12 and the contact plate 10. This ensures the structural connection is stable and has good adjustment and buffering capabilities, thereby effectively improving the installation accuracy and operational flexibility of the radar system under different detection attitudes.

[0029] Working principle: When the 900M ground-penetrating radar antenna ranging wheel needs to be rotated 90°, first, after the bracket 2 is set outside the mounting frame 6 and adjusted, the angle is fixed by the mounting bolt 7 passing through the sleeve 5 and the mounting nut 8. Then, an adjusting bolt 13 is passed through the mounting frame 6 and the inside of the mounting plate 9 on one side, and an adjusting nut 3 is tightened on the outer wall of the adjusting bolt 13 for fixation. Then, another adjusting bolt 13 is passed through the mounting frame 6 and on the inner wall of the adjusting bolt 12. After rotating the mounting frame 6 to adjust the angle of the ranging wheel body 4, the other adjusting nut 3 is tightened, thus achieving the effect of easily fixing the angle of the ranging wheel body 4.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
