Description

Technical Field

[0001] This invention relates to the field of ground penetrating radar technology, and in particular to a high-precision synchronous control lifting device for a DC motor driven ground penetrating radar instrument. Background Technology

[0002] Ground penetrating radar (GPR) is a non-destructive detection technology for targets or interfaces that are not visible underground or within objects. By transmitting and receiving high-frequency short-pulse electromagnetic waves through an antenna, it can accurately detect the location, shape, and structure of geological targets. It is widely used in fields such as geological disaster prevention and control, road and bridge construction, geological exploration, and archaeology.

[0003] Many ground-penetrating radar (GPR) devices rely on manual adjustments due to environmental interference and limitations of manual operation, a process that is cumbersome and time-consuming. In locations requiring adjustments to the detection height, current GPR equipment is ill-suited, leading to low efficiency, increased susceptibility to operational errors, and reduced accuracy due to improper height adjustments.

[0004] In detection scenarios with significant terrain undulations or protrusions, such as mountainous areas and farmland, traditional ground-penetrating radar equipment has many limitations in adjusting its height, making it difficult to flexibly adjust the height according to the usage scenario. When used in some special terrains, the detection accuracy is affected.

[0005] To solve the problems mentioned above, it is essential to invent a lifting device based on ground-penetrating radar detection. Summary of the Invention

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1: Reference Figures 1-3 This invention provides a high-precision synchronous control lifting device for a DC motor-driven ground-penetrating radar instrument, comprising: The trolley body 11 has a moving component installed on it and an installation station set on it. The installation station has a U-shaped structure. Placement component 12 is slidably connected to the installation station. The ground-penetrating radar instrument is placed inside placement component 12. A top plate is installed on the top of placement component 12. The lifting mechanism is installed on the trolley body 11 and is fixed to the top plate. It is used to control the lifting of the placement component 12. The transmission mechanism is installed on the trolley body 11 and is connected to the lifting mechanism. The navigation unit is mounted on the top surface of the top plate; A handrail is installed on the top front side of the trolley body 11. A mounting bracket 1 is installed on the handrail, and a host computer is installed on the mounting bracket 1. The navigator and transmission mechanism are both connected to the host computer.

[0026] During operation, the moving components of the vehicle body provide power, propelling the entire device within the detection area. Operators can use the handrail for directional control, balancing automatic and manual operation flexibility. A navigation unit on the top surface of the roof collects real-time information on the device's position, path, and attitude, transmitting this data to a host computer for driving control and height adjustment. Upon receiving information from the navigation unit, the host computer generates lifting control commands based on preset detection requirements and sends them to the transmission mechanism. Receiving the control signal from the host computer, the transmission mechanism precisely transmits power to the lifting mechanism. The lifting mechanism then moves the roof and placement component 12, causing them to slide (lift) stably along the U-shaped installation position, thereby adjusting the height of the ground-penetrating radar within the placement component 12 to ensure it is in the optimal detection position. During device operation, the navigation unit continuously provides position and path information, and the host computer optimizes control commands in real-time. Through the coordination of the transmission and lifting mechanisms, dynamic and high-precision adjustment of the ground-penetrating radar height is achieved, ensuring the stability of the detection process.

[0027] Further optimization of the scheme: the lifting mechanism includes two sets of lifting components, which are symmetrically installed on both sides of the top surface of the installation station. Each lifting component includes a screw jack 7, which is installed on the top surface of the trolley body 11. A flange-type screw 10 is installed on the top of the screw jack 7 and is fixed to the bottom surface of the top plate. Screw jacks 7 on the same side are connected by a connecting rod 9 and a coupling 8. Screw jacks 7 of adjacent lifting components are connected by a connecting rod 9 and a steering gear. A motor 13 is installed on the top surface of the trolley body 11 and is connected to the two sets of steering gears through the connecting rod 9.

[0028] The electric motor 13 on the top surface of the trolley body 11 provides power, and transmits torque to two sets of steering gears (such as bevel gear steering gears) through the connecting rod 9. The steering gears change the direction of power transmission (such as converting horizontal power to vertical power), driving the screw jacks 7 on both sides respectively. The screw jacks 7 on the same side are connected to the coupling 8 through the connecting rod 9 to achieve synchronous rotation of multiple screw jacks 7 on the same side; the lifting components on both sides are linked to the same electric motor 13 through the steering gear to ensure that the lifting actions on the left and right sides are completely symmetrical and to prevent the placement component 12 from tilting. The screw jack 7 converts the rotational motion of the electric motor 13 into the linear motion of the flange-type screw 10 (the nut inside the screw jack 7 engages with the screw, and the nut drives the screw to rise and fall when rotating). The flange-type screw 10 is fixed to the bottom surface of the top plate, thereby accurately pushing the placement component 12 to rise and fall along the U-shaped installation position, and the lifting height is continuously adjustable within the range of 0-62cm to meet the height requirements of different detection scenarios.

[0029] The scheme is further optimized. The transmission mechanism includes an electric motor 13, which is mounted on the top surface of the trolley body 11. The electric motor 13 is connected to two sets of steering gears through a connecting rod 9.

[0030] The torque output by the motor 13 is transmitted to two sets of steering gears through the connecting rod 9. The steering gears change the direction of power through gear meshing (for example, turning the horizontal output shaft of the motor 13 into a vertical transmission output), so that the power can drive the lifting components on both sides respectively. During the transmission process, the rigid connection between the connecting rod 9 and the steering gear ensures that the power loss is minimized. With the buffering effect of the coupling 8, transmission jamming caused by load fluctuations or installation deviations is avoided, so as to achieve smooth and precise power input of the lifting mechanism. It is the core power transmission link of "high-precision synchronous control".

[0031] Further optimization of the scheme: the handrail includes a hinge seat 15. Two sets of hinge seats 15 are symmetrically installed on the top surface of the trolley body 11. The two sets of hinge seats 15 are respectively connected to the mounting tubes via the rotating shaft 4. A push rod 2 is arranged between the two sets of mounting tubes. The push rod 2 has a U-shaped structure. The two ends of the push rod 2 are slidably connected to the mounting tubes. The side wall of the mounting tube is provided with a threaded hole. A positioning screw 3 is threadedly connected in the threaded hole. The end of the positioning screw 3 abuts against the push rod 2. The mounting bracket 1 is installed in the middle position of the push rod 2.

[0032] Two sets of hinge seats 15 are rotatably connected to the mounting tube via a rotating shaft 4, allowing the mounting tube to rotate around the hinge seats 15 (e.g., tilting forward or backward). Operators can adjust the hand-holding angle according to their height and operating habits, reducing labor intensity. The push rod 2 has a U-shaped structure, with both ends sliding inside the mounting tube, enabling the overall length of the handrail to be extended or retracted (e.g., shortening or lengthening the operating distance). After adjustment, tighten the positioning screw 3 on the side wall of the mounting tube. The end of the screw presses against the push rod 2, fixing the position of the push rod 2 through friction, ensuring the structure does not loosen during operation. The mounting bracket 1 installed in the middle of the push rod 2 provides stable support for the host computer, allowing operators to directly observe the navigation and control information of the host computer while holding the handrail, achieving integrated "operation-monitoring".

[0033] The design was further optimized so that component 12 includes a buffer box, which is slidably connected in the installation station and the top plate is fixed to the top surface of the buffer box.

[0034] The buffer box is slidably connected within the U-shaped installation position, and the ground-penetrating radar instrument is placed inside the buffer box. When the device travels on uneven ground or the lifting mechanism operates, the buffer box absorbs vibrations through its own shock-absorbing structure, preventing severe vibrations from causing a decrease in radar detection accuracy or damage to the instrument. The buffer box is fixed to the top plate and rises and falls synchronously with the lifting mechanism, while simultaneously sliding along the guide structure of the U-shaped installation position, ensuring the horizontal attitude stability of the ground-penetrating radar during lifting and lowering, further guaranteeing the accuracy of the detection data.

[0035] With further optimization, the lifting height of the screw jack 7 is 0-62cm.

[0036] The screw jack 7 internally contains a worm gear-worm wheel or gear-nut transmission pair. When the input end (the rotational power transmitted by the connecting rod 9) drives the worm / drive gear to rotate, the worm wheel / driven nut rotates accordingly. Since the nut and the flange-type screw 10 are engaged by threads, and the screw is constrained by the top plate and cannot rotate, the rotational motion of the nut is converted into the linear lifting motion of the screw. The lifting range of 0-62cm is limited by the effective thread length of the screw. Combined with the precise speed control of the motor 13 (such as the pulse number adjustment of a stepper motor), it can achieve millimeter-level or even higher precision height positioning, meeting the height adaptation requirements of ground penetrating radar in different terrains (such as depressions and raised ground).

[0037] The solution is further optimized so that the navigation unit includes a GPS navigator 14, which is fixed to the top surface of the top plate by a mounting bracket, and the GPS navigator 14 is connected to the host computer through a wireless transmission module.

[0038] The GPS navigator 14 is stably installed on the top surface of the roof via a fixed mount. It receives positioning signals from multiple satellites and calculates the device's latitude, longitude, altitude, speed, heading angle, and other information in real time. The positioning data is transmitted to the host computer in real time via a wireless transmission module (such as Bluetooth, 4G / 5G). The host computer combines the preset detection area map or path planning algorithm to generate real-time driving commands (such as steering and acceleration) and elevation adjustment commands, providing a spatial position reference for the device's autonomous navigation and altitude adaptive control.

[0039] Further optimization of the design includes the following moving components: rubber wheels 5, with four sets of rubber wheels 5 installed symmetrically in pairs on both sides of the trolley body 11.

[0040] Four sets of rubber wheels 5 are symmetrically distributed in pairs on both sides of the main body 11 of the vehicle (usually the front and rear wheel sets), driven by a DC motor to provide forward / backward power; the rubber material has the characteristics of good elasticity and strong grip, which can buffer the ground bumps (forming double shock absorption in conjunction with the buffer box of the mounting component 12), and adapt to various terrains such as grass, dirt road, and cement ground, ensuring that the device travels smoothly and reducing interference with the accuracy of ground penetrating radar detection.

[0041] Example 2, Reference Figure 4 In this embodiment, the screw jack 7 is controlled by a handwheel for lifting.
