Description

Technical Field

[0001] This utility model relates to the field of ground-penetrating radar auxiliary equipment technology, and in particular to a liftable ground-penetrating radar antenna towing device. Background Technology

[0002] In the field of ground exploration, ground-penetrating radar (GPR), as a highly efficient underground medium detection device, requires a trailer to work with a tractor to achieve large-scale mobile detection. The performance of the trailer directly affects the detection accuracy, equipment safety, and scene adaptability of the GPR antenna. Currently, GPR antenna trailers on the market generally have many limitations: some devices lack flexible height adjustment mechanisms, and the distance between the GPR antenna and the ground is fixed, making it impossible to adapt to different detection scenarios (such as rugged roads or different detection depth requirements), which can easily lead to antenna collisions and damage or interference with the detection signal; some devices, although possessing basic mobility functions, have poor shock absorption, and when traveling on bumpy roads, severe vibrations can directly affect the stability of the antenna, leading to deviations in detection data and even damage to delicate antenna components; still other devices have rudimentary support and flipping structure designs, making manual adjustment cumbersome and unable to achieve automated control, which not only increases the labor intensity of operators but also makes it difficult to guarantee adjustment accuracy, thus restricting detection efficiency. For example, a three-dimensional ground-penetrating radar antenna towing device is proposed in a Chinese patent, patent publication number CN221574206U. When using the above patent, the distance between the ground-penetrating radar antenna and the ground can be adjusted by rotating the antenna fixing rod to adapt to different road conditions. At the same time, the shock-absorbing component composed of a first slider, a second slider, a first spring, and a second spring reduces the bumps on the main frame and prevents the antenna from being damaged by vibration. In addition, auxiliary plates and auxiliary wheels are set to assist the movement of the device, which improves the practicality of the device to a certain extent. However, the aforementioned patent only addresses the initial adjustment of antenna height and basic vibration reduction, failing to achieve precise and automated control of antenna height. The manual adjustment method of the antenna fixing rod makes it difficult to accurately control height parameters, which cannot meet the requirements of high-precision detection scenarios. Furthermore, the patent lacks a flexible, tiltable, and adjustable support arm and wheel linkage structure. The switching between the wheel and support components lacks automated drive and precise control mechanisms, requiring manual intervention when moving on complex road surfaces or switching detection operations, resulting in low operational efficiency and difficulty in ensuring stable support of the device under different working conditions. In addition, the overall structure of the patent does not form a highly coordinated lifting-tilting-vibration integrated system. When dealing with diverse detection scenarios (such as high-frequency operations and heavy-specification antenna mounting), its load-bearing capacity and operational stability are insufficient, failing to fully meet the efficient, accurate, and automated detection requirements of modern ground-penetrating radar.

[0003] Therefore, we propose a liftable ground-penetrating radar antenna towing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a liftable ground-penetrating radar antenna towing device, which solves the problems of low antenna height adjustment accuracy, lack of automatic flipping support structure, and poor adaptability to complex road conditions in existing devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A liftable ground-penetrating radar antenna towing device includes a towing connector, which is fixedly installed on the towing base of a vehicle, and further includes: A lifting assembly is provided on one side of the towing connector, and a radar mounting base is installed on the towing connector through the lifting assembly. A set of mounting holes are provided around the radar mounting base for installing a ground-penetrating radar antenna. A connecting seat is fixedly installed on the top of the radar mounting base, and the radar mounting base is connected to the lifting assembly through the connecting seat; A flipping assembly is provided at the center of the bottom of the radar mounting base, and a set of support arms is installed on each side of the radar mounting base near the flipping assembly, and wheels are installed on the other end of each set of support arms. Preferably, the lifting assembly includes a mounting frame, an electric telescopic rod, a hydraulic damper, and a connector. An L-shaped mounting frame is fixedly installed on one side of the top of the towing connector, and an electric telescopic rod is hinged to the bottom of the middle part of the mounting frame. A hydraulic damper is rotatably mounted on the bottom end of the trailer connecting seat, and a connector is fixedly mounted on the output end of the hydraulic damper. The lifting assembly is hinged to the connecting seat through the connector at the bottom end of the hydraulic damper. Preferably, the lifting assembly further includes a first link, a second link, and a support rod. The first link is hinged to one end of the mounting bracket away from the towing connection seat, and the second link is hinged to the other end of the first link. The first link is hinged to the output end of the electric telescopic rod on the side closest to the second link, and the other end of the second link is hinged to the side of the hydraulic damper closest to the output end. The hydraulic damper has a set of support rods hinged to each side near the connector, and the other ends of the two sets of support rods are hinged to the connector. Preferably, the flipping assembly includes a threaded screw, a drive motor, and a rack, and the bottom of the radar mounting base is provided with a slot in the middle, and the threaded screw is rotatably installed in the slot; A drive motor is fixedly installed on the side of the radar mounting base near the end of the threaded screw, and the output shaft of the drive motor is fixedly connected to the threaded screw. A rack is slidably installed in the slot at the bottom of the radar mounting base, and the rack is threadedly engaged with the threaded lead screw. Preferably, a baffle is fixedly installed at the bottom end of the radar mounting base near the middle of the slot, and a gear that meshes with a rack is rotatably installed on the side of the radar mounting base near the baffle. Preferably, a set of ten-element plates is fixedly installed on both sides of the gear, and a set of rotating rods is fixedly installed on the other end of each of the two sets of ten-element plates; The other ends of the two sets of rotating rods extend to both sides of the radar mounting base and are rotatably mounted together at the bottom of the radar mounting base, and the middle parts of the two sets of rotating rods are respectively fixedly mounted together with the support arm.

[0006] This utility model has at least the following beneficial effects: The multi-link lifting structure driven by the electric telescopic rod can precisely control the height of the radar mounting base and antenna to meet the needs of different detection scenarios. The flipping component uses a drive motor and a lead screw-rack-gear transmission to automatically adjust the state of the support arm and wheels without manual intervention. This avoids manual operation errors, reduces the labor intensity of operators, and is suitable for long-term, high-frequency detection operations.

[0007] This utility model also has the following beneficial effects: The hydraulic damper can buffer the impact force during lifting and moving, reducing the impact of vibration on the antenna and detection data. Combined with the triangular support structure, it enhances the connection strength and anti-sway capability. The ten-element compensation for installation and movement deviation ensures synchronous transmission of the support arm, making the device move smoothly on complex road surfaces and providing stable support during detection, taking into account the adaptability of large-scale operation and complex environment.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0012] Reference Figure 1-5 A liftable ground-penetrating radar antenna towing device includes a towing connector 1, which is fixedly installed on the towing base of a vehicle, and further includes: A lifting assembly 3 is provided on one side of the towing connector 1, and a radar mounting base 2 is installed on the towing connector 1 through the lifting assembly 3. A set of mounting holes are provided around the radar mounting base 2 for installing ground penetrating radar antennas. A connecting seat 4 is fixedly installed on the top of the radar mounting base 2, and the radar mounting base 2 is connected to the lifting assembly 3 through the connecting seat 4; A flipping assembly is provided at the center of the bottom of the radar mounting base 2, and a set of support arms 5 are respectively installed on both sides of the radar mounting base 2 near the flipping assembly, and wheels are installed at the other end of both sets of support arms 5. Furthermore, the lifting assembly 3 includes a mounting frame 6, an electric telescopic rod 7, a hydraulic damper 8, and a connector 12. An L-shaped mounting frame 6 is fixedly installed on one side of the top of the towing connector 1, and an electric telescopic rod 7 is hinged to the bottom of the middle part of the mounting frame 6. A hydraulic damper 8 is rotatably mounted on the bottom end of the towable connector 1, and a connector 12 is fixedly mounted on the output end of the hydraulic damper 8. The lifting assembly 3 is hinged to the connector 4 via the connector 12 at the bottom end of the hydraulic damper 8. The electric telescopic rod 7, as the active drive component, can precisely control the start, stop, and speed of the lifting action, enabling convenient adjustment of the height of the radar mounting base 2 and meeting the differentiated requirements for the height of the ground-penetrating radar antenna in different detection scenarios. At the same time, the hydraulic damper 8 rotatably mounted on the bottom end of the towable connector 1 can effectively buffer the impact force generated by road bumps or the start and stop of the action during the lifting of the radar mounting base 2, reducing the impact of vibration on the ground-penetrating radar antenna and ensuring the accuracy of the detection data. The connector 12 enables flexible hinge between the hydraulic damper 8 and the connector 4, making the lifting action smoother, avoiding component wear caused by rigid connections, and extending the overall service life of the device. Furthermore, the lifting assembly 3 also includes a first link 9, a second link 10 and a support rod 11. The first link 9 is hinged to one end of the mounting bracket 6 away from the towing connecting seat 1, and the second link 10 is hinged to the other end of the first link 9. The first link 9 is hinged to the output end of the electric telescopic rod 7 on the side near the second link 10, and the other end of the second link 10 is hinged to the side of the hydraulic damper 8 near the output end. A set of support rods 11 are hinged to both sides of the hydraulic damper 8 near the connector 12, and the other ends of both sets of support rods 11 are hinged to the connector 12. The hinged connection between the first link 9 and the mounting bracket 6, as well as its linkage design with the electric telescopic rod 7 and the second link 10, converts the linear driving force of the electric telescopic rod 7 into the lifting power of the radar mounting base 2. The force transmission and dispersion through multiple links reduces the stress on a single component, improves the load-bearing capacity of the lifting assembly 3, and can accommodate heavier ground-penetrating radar antennas. The hinge between the second link 10 and the hydraulic damper 8 further optimizes the power transmission path, ensures the stability and synchronization of the lifting action, and prevents the radar mounting base 2 from tilting during lifting. In addition, the two sets of support rods 11 form a triangular support structure between the hydraulic damper 8 and the connector 12, which greatly enhances the structural strength of the connection between the connector 12 and the hydraulic damper 8, prevents deformation of the connection due to the weight of the radar mounting base 2 and the antenna, and improves the anti-sway capability during the lifting process, so that the ground penetrating radar antenna always maintains a stable detection posture. Furthermore, the flipping assembly includes a threaded screw 13, a drive motor 14, and a rack 16. The bottom of the radar mounting base 2 has a slot in the middle, and the threaded screw 13 is rotatably installed in the slot. A drive motor 14 is fixedly installed on the side of the radar mounting base 2 near the end of the threaded screw 13, and the output shaft of the drive motor 14 is fixedly connected to the threaded screw 13. A rack 16 is slidably installed in a slot at the bottom of the radar mounting base 2, and the rack 16 is threadedly engaged with a lead screw 13. The drive motor 14 is fixedly connected to the lead screw 13, ensuring lossless power transmission. This allows for precise control of the rotation angle and speed of the lead screw 13, which in turn drives the rack 16 to slide smoothly within the slot through the threaded engagement. This lead screw drive method features high transmission accuracy and smooth operation, providing precise linear driving force for the subsequent flipping action of the radar mounting base 2, avoiding errors from manual adjustment. Furthermore, it eliminates the need for manual intervention, achieving automated control of the flipping action, reducing the labor intensity of operators, and is particularly suitable for long-term, high-frequency detection operations, thus improving overall detection efficiency. Furthermore, a baffle 15 is fixedly installed at the bottom of the radar mounting base 2 near the center of the slot, and a gear 17 that meshes with the rack 16 is rotatably installed on the side of the radar mounting base 2 near the baffle 15. This prevents the rack 16 from disengaging from the threaded screw 13 or colliding with the inner wall of the slot due to excessive displacement during sliding, ensuring the safety and reliability of the flipping assembly transmission. The gear 17 meshing with the rack 16 converts the linear sliding of the rack 16 into the rotational motion of the gear 17, providing rotational power for the subsequent flipping of the radar mounting base 2, achieving efficient conversion of motion mode. The meshing transmission between the gear and rack has the advantages of stable transmission ratio and high power transmission efficiency, ensuring that each segment of displacement of the rack 16 can be accurately converted into the corresponding rotation angle of the gear 17, providing precise assurance for the flipping angle control of the radar mounting base 2, avoiding detection angle deviation caused by transmission errors, and improving the detection accuracy of the ground penetrating radar. Furthermore, a set of ten-element plates is fixedly installed on both sides of the gear 17, and a set of rotating rods 18 is fixedly installed on the other end of each of the two sets of ten-element plates. The other ends of the two sets of rotating rods 18 extend to both sides of the radar mounting base 2 and are rotatably mounted together at the bottom of the radar mounting base 2. The middle parts of the two sets of rotating rods 18 are respectively fixedly mounted to the support arms 5. The cross-shaped structure can effectively compensate for possible installation deviations or angular offsets during movement between the gear 17 and the rotating rods 18, ensuring that power transmission will not be interrupted or lost due to angle issues, thus achieving flexible power transmission. The two sets of rotating rods 18 are fixedly connected to the cross-shaped structure and the support arms 5 respectively, synchronously transmitting the rotational power of the gear 17 to the two support arms 5 on both sides, driving the support arms 5 to rotate, thereby realizing the angle adjustment of the wheels. This synchronous transmission structure can ensure that the rotation angles of the two support arms 5 are completely consistent, avoiding problems such as device tilting and unstable driving caused by excessively fast or slow rotation on one side. Especially during the flipping of the radar mounting base 2 or the movement of the device, it can ensure that the wheels always maintain a stable support and walking state, improving the device's ability to pass through complex road environments and its stability. In summary: The radar mounting base 2 is fixed to the car trailer base via the towing connector 1. In the initial state, the radar mounting base 2 is connected to the lifting assembly 3 via the connector 4. The ground-penetrating radar antenna is installed in the mounting holes around the radar mounting base 2. The support arm 5 and the bottom wheel are in a ready-to-work state. The components of the tilting assembly (threaded screw 13, drive motor 14, rack 16, etc.) are in an initial static state. When it is necessary to adjust the height of the ground-penetrating radar antenna, the electric telescopic rod 7 is activated. Its output end generates linear telescopic force, which drives the first connecting rod 9 to rotate around the hinge point with the mounting bracket 6. On the other hand, the first connecting rod 9 drives the second connecting rod 10 to swing. The second connecting rod 10 then drives the hydraulic damper 8 to rotate around the rotating mounting point at the bottom of the towing connector 1. This, in turn, drives the radar mounting base 2 to lift and lower as a whole through the hinge between the connector 12 and the connector 4. At the same time, the hydraulic damper 8 absorbs the impact force during the lifting and lowering process to reduce vibration. The two sets of support rods 11 A triangular support structure is formed to stabilize the connection points, ensuring the antenna maintains a stable detection posture. When it is necessary to adjust the support arm 5 and the wheel status, the drive motor 14 is started, which drives the threaded screw 13 to rotate, causing the rack 16, which is threaded to it, to slide linearly along the slot at the bottom of the radar mounting base 2 (the baffle 15 limits the sliding range of the rack 16). The rack 16 then drives the meshing gear 17 to rotate, and the gear 17 transmits power to the rotating rod 18 through the two crossbars on both sides, causing the rotating rod 18 to rotate, which in turn causes the support arm 5, which is fixedly connected to the rotating rod 18, to rotate, thereby realizing the wheel angle adjustment. When moving, the wheels contact the ground to assist in smooth movement, and when detecting, the wheels leave the ground to avoid interference, and the support arm 5 forms symmetrical support to prevent tipping. Overall, through the coordinated linkage of the lifting component 3 and the flipping component, the device realizes the full-process function of "height adjustment - posture stabilization - mobile support - detection guarantee". It can not only complete large-scale ground detection operations with the vehicle, but also flexibly adapt to different scenarios, taking into account detection accuracy, ease of operation and equipment lifespan.
