Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle-mounted ground penetrating radar, in particular to a vehicle-mounted bracket and a lifting device for the ground penetrating radar. Background Art
[0002] Ground-penetrating radar, a key device that uses high-frequency electromagnetic waves to detect the distribution of underground media, has been widely used in road damage detection, underground pipeline network surveys, and geological exploration. The large-scale construction of urban roads, rail transit, and underground spaces has led to increased soil erosion, the creation of potential cavities, and other hidden dangers, creating an increasingly urgent need for efficient and accurate ground-penetrating radar detection.
[0003] Traditional vehicle-mounted brackets often use a rigid mounting method. This can easily cause unexpected vibrations and displacement when the antenna encounters bumps or uneven road surfaces during vehicle travel. While existing technologies attempt to adjust the height through simple lifting mechanisms, insufficient adjustment precision is common. Mechanical gaps and structural deformation further amplify errors, directly affecting radar beam directivity and echo signal quality. Furthermore, conventional brackets lack adaptability to dynamic changes in the detection environment. Especially when operating on non-level surfaces, the antenna's attitude cannot compensate for tilt in real time, causing the beam path to deviate significantly from the preset model and significantly reducing the reliability of the detection data.
[0004] In terms of mobile deployment efficiency, traditional brackets require multi-point fastener installation, a cumbersome and time-consuming process. Existing quick-release mechanisms often rely on repeated manual positioning and calibration, and fail to ensure reliable connection strength. Prolonged vibration during vehicle movement can easily loosen connections, increasing the risk of overall bracket displacement and indirectly causing the radar acquisition path to deviate from the preset trajectory. Furthermore, the transfer of equipment after detection also lacks dedicated lifting equipment, and manual handling can easily cause damage to the precision radar equipment.
[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0012] Furthermore, in order to use the L-shaped welding structure to connect the main pole and the installation cross bar, reinforcement ribs are used to improve the node strength; the installation cylinders at both ends of the installation cross bar are inserted into the vertical grooves of the installation box at the bottom of the support frame, and radial locking is achieved by quick-release bolts; thereby simplifying the disassembly and assembly process of the vehicle-mounted bracket and the vehicle, and at the same time, the docking joint is adapted to the towing interface of different models to improve the reusability of the equipment.

[0038] In one embodiment, for the above-mentioned suspension lifting mechanism 2, the suspension lifting mechanism 2 includes a fixed base 201 arranged at the bottom of one side of the support frame 1, a fixed shaft seat 202 is arranged at the top of the other side of the support frame 1, a lifting cylinder 203 is arranged on the top of the fixed base 201, a tripod 204 is arranged between the two fixed shaft seats 202 and is kept in active connection, and the output end of the lifting cylinder 203 is kept in active connection with the top corner end of the tripod 204; the bottom of the two isosceles sides of the tripod 204 are both provided with guide rails 205; both sides of the top of the radar pod 3 are provided with lifting The boom 206 and the lifting connecting rod 207 are arranged between the top ends of the two lifting booms 206.

[0040] In one embodiment, for the above-mentioned connecting frame 6, the connecting frame 6 includes an L-shaped connecting main rod 601, and an installation cross rod 602 is provided at one end of the connecting main rod 601 close to the supporting frame 1, and reinforcing ribs 603 are provided on both sides of the installation cross rod 602 and between the connecting main rod 601, and installation cylinders 604 are provided at both ends of the installation cross rod 602; a docking joint 605 is provided at the end of the connecting main rod 601 away from the supporting frame 1, so as to use an L-shaped welding structure to connect the main rod 601 and the installation cross rod 602, and the reinforcing ribs 603 improve the node strength; the installation cylinders 604 at both ends of the installation cross rod 602 are inserted into the vertical slots 14 of the installation box 13 at the bottom of the supporting frame 1, and radial locking is achieved by quick-release bolts 15; thereby simplifying the disassembly and assembly process of the vehicle-mounted bracket and the vehicle, and at the same time, the docking joint 605 is adapted to the traction interface of different vehicle models, thereby improving the reusability of the equipment.
[0041] In one embodiment, for the above-mentioned support frame 1, mounting boxes 13 are provided on both sides of the bottom of the support frame 1, and a vertical groove 14 is provided on the top of the mounting box 13 to match the mounting cylinder 604. A quick-release bolt 15 is inserted into the top of the mounting box 13, thereby eliminating the connection gap through the thread locking force, avoiding the risk of the bracket and the connecting frame 6 being separated when the vehicle starts or stops suddenly.
[0042] In one embodiment, for the above-mentioned main box body 4, a transmission chamber 16 that cooperates with the lifting cylinder 203 is provided on one side of the main box body 4, and positioning grooves 17 are respectively opened on both sides of the top of the main box body 4; the bottoms on both sides of the top box 5 are fixedly connected with the positioning grooves 17 by bolts, so that the top box 5 is fixed to the positioning grooves 17 at the top of the main box body 4 by the bottom bolts, forming a sealed electrical cabin, protecting the radar control circuit from rain erosion, and providing a centralized management channel for the cables.
[0043] In one embodiment, for the above-mentioned top box 5, transmission grooves 18 cooperating with the tripod 204 are provided on both sides of the top box 5; a placement rack 19 cooperating with the connecting frame 6 is provided at the top of the top box 5, so that the transmission grooves 18 on both sides of the top box 5 reserve space for the lifting and swinging of the tripod 204 to avoid interference between the box body and the moving parts; the placement rack 19 on the top accommodates the disassembled connecting frame 6 to reduce the damage to the exposed parts during transportation.
[0044] It should be noted that the oil cylinders in the vehicle-mounted bracket are mainly the lifting oil cylinder 203 and the lifting oil cylinder 23. The structure of the oil cylinder consists of a cylinder barrel, a piston, a piston rod, a seal and a guide sleeve. The surface of the piston rod is carburized and quenched and hard chrome-plated to improve wear resistance. The seal adopts a nitrile rubber or polyurethane combination seal ring to ensure high-pressure leakage prevention performance; the oil cylinder control can be achieved through manual hydraulic operation, that is, the oil circuit valve is directly adjusted by the handle to drive the oil cylinder to extend and retract to complete the coarse adjustment of the radar pod 3. It can also adopt an electro-hydraulic proportional control method to accurately adjust the flow and opening of the proportional valve through electrical signals, and cooperate with a displacement sensor (such as a position detection unit integrated near the limit sleeve 12 of the I-frame 10, which can be optionally installed, not shown in the figure) to provide real-time feedback on the pod height, thereby achieving millimeter-level precision positioning and overload protection functions. The electrical equipment operates on the vehicle's power supply system (12V / 24V DC) and includes a control unit (PLC or dedicated controller) integrated into the main box 4, a displacement sensor, a vibration sensor, and a power management module. The control logic of the two cylinders is as follows: the controller drives the lifting cylinder 203 according to the preset height command and uses the guide rail 205 to constrain the motion trajectory. At the same time, the vibration sensor monitors road impact and links the double wishbone suspension 9 to dynamically adjust the damping force to suppress the shaking of the radar pod 3. If the displacement of the radar pod 3 exceeds the safety threshold, the limit switch is triggered to cut off the cylinder oil circuit to prevent overload damage to the mechanical structure.
[0045] The ground-penetrating radar used in radar pod 3 must meet the physical interface and electrical compatibility requirements preset by the bracket. The power interface (12V / 24V DC) and data output (such as RS485 / CAN bus) must be compatible with the vehicle's onboard system and have a protection level of IP65 or above to resist external environmental corrosion. The radar transmits high-frequency electromagnetic pulses (typical frequency band covers 100MHz to 2.5GHz) into the ground, receives reflected waves from the stratum interface, and analyzes the time difference data to calculate the target depth and medium properties. In actual operation, it can switch between continuous scanning mode (emitting pulses at fixed intervals to generate an underground profile when the vehicle is moving at a constant speed) or point measurement mode (high-density sampling in the parked state to improve local resolution). Users can choose an appropriate model (such as a shielded antenna that resists electromagnetic interference or a high-sensitivity unshielded antenna) according to their detection needs.
[0046] In addition, the present invention takes the mechanical structure design of the vehicle-mounted bracket as the core body, and the functional realization of the vehicle-mounted bracket is concentrated on mechanical innovations such as the precise height adjustment of the suspension lifting mechanism 2, the active shock absorption of the double wishbone suspension 9, and the quick-release connection of the connecting frame 6; the hydraulic control unit of the oil cylinder, the electrical sensor system and the detection equipment in the radar pod are all regarded as flexibly configurable auxiliary subsystems. The user only needs to ensure that the selected electrical equipment meets the preset physical bearing interface of the bracket, such as the installation size of the radar pod 3, the compatibility of electrical parameters (power supply voltage and communication protocol) and environmental protection standards, and can independently select and realize plug-and-play according to the specific application scenario. The mechanical functional integrity of the vehicle-mounted bracket is not restricted by a specific brand or model of electrical equipment.
[0047] According to another embodiment of the present invention, please refer to Figure 7 A lifting device for a vehicle-mounted bracket of a ground penetrating radar is also provided. The lifting device includes a vehicle-mounted mounting base 20 arranged at the bottom of the detection vehicle. Swing cylinders 21 are provided at both ends of one side of the vehicle-mounted mounting base 20. A lifting arm 22 is provided on the inner side of the swing cylinder 21. A lifting cylinder 23 is provided between the bottom of the lifting arm 22 and the vehicle-mounted mounting base 20. The other ends of the swing cylinder 21 and the lifting arm 22 are movably connected to a lifting plate 24. Moving wheel limiting grooves 25 are provided at the four corners of the top of the lifting plate 24.
[0048] Specifically, the lifting device is fixed to the chassis of the detection vehicle through the vehicle-mounted mounting bracket 20, the lifting cylinder 23 drives the lifting arm 22 to lift vertically, and at the same time the swing cylinder 21 adjusts the horizontal inclination angle of the lifting arm 22; the moving wheel limit groove 25 of the lifting plate 24 accurately engages the bracket moving wheel 7, realizing the loading and unloading of the vehicle-mounted bracket as a whole and the vehicle, solving the efficiency and safety problems of manual handling.
[0049] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.
[0050] In actual application, firstly, the docking joint 605 of the connecting frame 6 is docked with the interface reserved at the rear of the detection vehicle or the bottom of the lifting plate, such as Figure 8 As shown. During operation, the connector 605 connecting the front end of the main rod 601 is inserted into the vehicle's towing interface. Simultaneously, the mounting cylinders 604 at both ends of the mounting crossbar 602 are inserted into the vertical slots 14 of the mounting box 13 at the bottom of the support frame 1. The quick-release bolts 15 are tightened to achieve rigid locking. Before the vehicle moves, the operator activates the suspension lifting mechanism 2: the lifting cylinder 203 pushes the top corner of the tripod 204, causing it to rotate around the fixed axle seat 202. The guide rail 205 at the bottom of the tripod 204 drives the lifting link 207 to move synchronously. The lifting link 207, via the lifting boom 206, pulls the radar pod 3 vertically down to the set height. At this point, the limiting sleeve 12 on the I-frame 10 constrains the swing amplitude of the lifting boom 206, ensuring that the radar antenna maintains a stable posture. The protective space formed by the main box 4 and the top box 5 isolates it from external interference, while the transmission chamber 16 encloses the moving components of the lifting cylinder 203.
[0051] When the vehicle reaches the detection area, the double-wishbone suspension 9 performs its core shock-absorbing function: road impacts on the moving wheels 7 are transmitted through the double-wishbone lever structure to the fixed footplate 8, where they are significantly attenuated, preventing vibration energy from being transmitted through the support frame 1 to the radar pod 3. If the detection height needs to be adjusted during radar acquisition, the lift cylinder 203 adjusts the inclination angle of the tripod 204 in real time, allowing the radar pod 3 to be precisely raised and lowered within the linear constraints of the guide rails 205. Transmission slots 18 on both sides of the top box 5 provide space for the tripod 204 to swing freely, preventing mechanical interference.
[0052] After the detection mission is completed, Figure 9 As shown, the lifting device retracts the bracket: the lifting cylinder 23 on the vehicle mounting base 20 pushes the lifting arm 22 vertically upward, while the swing cylinder 21 adjusts the horizontal angle of the lifting arm so that the moving wheel retaining grooves 25 of the lifting plate 24 align with the moving wheels 7 at the bottom of the bracket. Once the moving wheels 7 engage the retaining grooves, the lifting cylinder 23 continues to retract, lifting the entire bracket off the ground and locking it to the vehicle chassis. The connecting frame 6 can now be removed and stored in the storage rack 19 of the top box 5, ensuring safe transportation of the equipment.
[0053] To sum up, with the help of the above-mentioned technical solution of the present invention, the operational convenience, environmental adaptability and long-term reliability of the ground penetrating radar system are significantly improved through modular design and overall integration; the overall structure realizes the rapid deployment and stable operation of the radar equipment through the coordinated cooperation of the support frame 1, the suspension lifting mechanism 2, the main box 4 and the connecting frame 6; protective components such as the main box 4 and the top box 5 effectively isolate external environmental interference and reduce the need for manual intervention; and the support of the moving wheels 7 and the suspension device enhances the dynamic stability of the bracket under different road conditions, ensuring the continuity and accuracy of radar data acquisition; it not only simplifies the on-board operation process and reduces the complexity of the setting, but also provides consistent performance in a variety of detection scenarios, laying a solid physical foundation for subsequent data analysis. By designing a suspension lifting mechanism 2, precise and stable vertical control is provided. Through the linkage mechanism of the tripod 204, the guide rail 205 and the lifting cylinder 203, the movement of the radar pod 3 is ensured to be smooth and adjustable, avoiding position offset or vibration during the movement of the vehicle; the lifting cylinder 203 drives the movement of the tripod 204, and the transmission through the guide rail 205 and the lifting link 207 realizes reliable adjustment of the height of the radar pod 3; at the same time, the integration of the limit sleeve 12 further constrains the lateral swing during the lifting process, maintaining the directional stability of the radar equipment; effectively eliminating the risk of data jitter caused by bumpy roads, and can complete highly customized settings without relying on complex external tools, significantly improving the quality of radar signals. The L-shaped connecting main rod 601 of the connecting frame 6 and the vertical slot 14 of the installation box 13 are locked by the quick-release bolt 15, so that fast disassembly and installation can be achieved, which significantly shortens the task interval time; with the help of the automatically lifting lifting device, the vehicle-mounted bracket can be flexibly transported to the interior of the detection vehicle, avoiding unnecessary damage to the vehicle-mounted bracket caused by road noise when it is not in operation, and solving the defects of the trailer-type bracket that is difficult to reverse and has poor passability.
