Technical Field
[0001] This invention relates to the field of road surveying technology, specifically to a sampling device and sampling method for road surveying. Background Technology
[0002] Road surveying and sampling is a fundamental step in road engineering design and construction. By collecting samples from underground strata at different depths, it provides crucial data for subgrade stability assessment, pavement material selection, and foundation treatment plan formulation. As road construction expands into complex terrains (such as mountains, wetlands, and permafrost regions), traditional sampling equipment has gradually revealed its limitations, including insufficient adaptability, low sampling accuracy, and limited automation, making it difficult to meet the demands of modern engineering for efficient and precise surveying.
[0003] In summary, traditional equipment has significant limitations in terms of mobility, sampling accuracy, sample protection, and adaptability to complex environments. There is an urgent need to develop a new type of sampling equipment that integrates lightweight support, multi-angle adjustment, layered storage, intelligent media delivery, and fully automatic control to improve the quality and efficiency of road surveying. Summary of the Invention
[0004] The purpose of this invention is to provide a sampling device and sampling method for road surveying, so as to solve the problems mentioned in the background art.
[0005] To address the aforementioned technical problems, this invention provides the following technical solution: a sampling device and method for road surveying, comprising a drilling rig, which includes a support system, a sampling execution mechanism, a drive system, an intelligent control system, a sample storage module, and auxiliary functional components; the support system includes a lightweight frame and a wheel structure; the sampling execution mechanism adopts a double-tube concentric sampling cylinder structure, including a bracket, a fixed frame, a hydraulic structure, a metal cylinder, an inner cylinder, a drive structure, and a drill rod; the fixed frame is connected to the lightweight frame via the bracket and its rotation angle is adjusted via the hydraulic structure; the sample storage module includes a telescopic rod, a storage cylinder, and six independent storage compartments, each containing a drive component, a push rod, and a push plate; the auxiliary functional components include a metal frame, lighting equipment, an intelligent pump valve, and a storage bin, with the intelligent pump valve connected to the storage bin via a flexible hose; the drive system provides power to each module, and the intelligent control system enables automated monitoring and adjustment.
[0006] According to the above technical solution, the lightweight frame is welded from high-strength aluminum alloy profiles; the wheel structure is equipped with off-road tires with a special tread design.
[0007] According to the above technical solution, two extension plates are welded to the rear end of the fixed frame. The extension plates increase the distance between the fixed frame and the bracket, so that the fixed frame has no direct contact with the lightweight vehicle frame. The output end of the hydraulic structure is connected to the fixed frame through a bearing to form a rotatable linkage mechanism, which drives the fixed frame to rotate around the bracket.
[0008] According to the above technical solution, the inner cylinder is connected to the metal cylinder by a metal plate. The inner cylinder is equipped with a protective shell. The drive structure is fixedly installed inside the protective shell. The output end of the drive structure is connected to the drill rod. The outer wall of the drill rod is machined with a spiral guide groove.
[0009] According to the above technical solution, all telescopic rods are installed in the same storage cylinder, the bottom of which is a hollow structure and fitted with drill rods; there are six independent storage chambers, each corresponding to the HH depth layer, and the drive unit in each storage chamber is connected to the push plate through the push rod. The push plate realizes the opening / sealing of the storage chamber and the pushing of samples.
[0010] According to the above technical solution, a first intelligent pump valve and a second intelligent pump valve are symmetrically arranged at both ends of the metal frame, which are connected to the first motor and the second motor respectively, and can adjust the spray angle; a precision metering nozzle is installed at the bottom of the first intelligent pump valve and the second intelligent pump valve, and is connected to the first discharge valve and the second discharge valve set at the top of the storage bin through an elastic hose.
[0011] According to the above technical solution, when the drill rod drills to the specified depth layer, the intelligent control system controls the drive component of the corresponding storage compartment to drive the push plate to retract inward to open the compartment door, while the push plates of other storage compartments remain flush with the compartment door in a sealed state; after the sample is stored, the drive component applies pressure to compact the sample to prevent cross-contamination.
[0012] According to the above technical solution, the storage silo is divided into a first warehouse and a second warehouse. The first warehouse stores fine sand to prevent subsidence in the drilling area. The second warehouse stores defreezing agent or diluent according to the ground conditions and releases it quantitatively through a second intelligent pump valve.
[0013] According to the above technical solution, high-strength slide rails are provided on both sides of the fixed frame, and the metal cylinder is slidably connected to the slide rails through an outwardly extending sliding support structure, so as to realize the extension or retraction movement of the metal cylinder along the axial direction of the fixed frame.
[0014] According to the above technical solution, the drive system drive process includes: starting the wheel structure to move to the exploration area, then activating the hydraulic structure to adjust the drill rod angle, then driving the drill rod to rotate and drill, then the metal cylinder moves down along the slide rail to achieve deep drilling, so that the telescopic rod drives the storage cylinder to move synchronously, and finally the layered storage chamber collects samples according to the depth, and the intelligent pump valve releases the medium quantitatively.

[0016] The compaction function of the push plate inside the storage compartment greatly increases the retention rate of the sample layer structure integrity, solving the sample damage problem caused by traditional mixed storage; the spiral guide groove on the outer wall of the drill rod further prevents sample backflow and ensures improved sample transfer efficiency.

[0025] 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.
[0026] Please see Figure 1-6 This invention provides a technical solution: a sampling device and method for road surveying, comprising a drilling rig 1, which consists of a support system, a sampling execution mechanism, a drive system, an intelligent control system, a sample storage module, and auxiliary functional components. The support system, serving as the basic frame of the device, includes a lightweight frame 2 welded from high-strength aluminum alloy profiles, and a wheel structure 3 equipped with a special tire tread design for flexible movement in muddy terrain.
[0027] The sampling execution mechanism is responsible for performing precise sampling tasks. The sampling execution mechanism is the core functional module and adopts a double-tube concentric sampling cylinder structure. Two brackets 4 are welded to the front end of the lightweight frame 2. A fixed frame 5 is installed between the two brackets 4 by bearings. Two extension plates 6 are welded to the rear end of the fixed frame 5 for connection with the brackets 4. The extension plates 6 increase the distance between the fixed frame 5 and the brackets 4, so that the fixed frame 5 has no direct contact with the lightweight frame 2 during operation.
[0028] The lightweight frame 2 has a hydraulic structure 7 at its front end. The output end of the hydraulic structure 7 is connected to the fixed frame 5 via a bearing, ensuring smooth movement and reducing friction. The fixed frame 5, through its fixed connection point with the bracket 4 and its connection to the output end of the hydraulic structure 7, forms a rotatable linkage mechanism. This allows the fixed frame 5 to rotate around the bracket 4, thereby precisely adjusting the position and angle of the sampling actuator to adapt to different sampling needs. Simultaneously, the output end of the hydraulic structure 7 has a telescopic function, allowing its length to be flexibly adjusted according to operating commands to provide the required push-pull force, supporting efficient and reliable mechanical motion control.
[0029] The sampling actuator includes a metal cylinder 8 mounted on a fixed frame 5, which serves as an external support structure. An inner cylinder 10 is securely connected to the inner cylinder 8 via a metal plate 9. The inner cylinder 10 houses and protects the internal components. A protective shell 11 is housed inside the inner cylinder 10, and a drive structure 12 is fixedly installed within the protective shell 11. The drive structure 12 provides power output, and a drill rod 13 is fixedly installed at its output end. The drill rod 13 performs the core function of the sampling operation. The entire mechanism is compactly designed to ensure coordinated operation of all components, achieving an efficient and stable sampling process.
[0030] A spiral guide groove is machined on the outer wall of drill rod 13 to prevent sample backflow;
[0031] The sample storage module includes telescopic rods 14, with each metal plate 9 having a telescopic rod 14 fixedly installed at its bottom. All telescopic rods 14 are mounted on the same storage cylinder 15, allowing the storage cylinder 15 to completely enclose the drill rod 13. The bottom of the storage cylinder 15 is designed with a hollow structure to facilitate the smooth passage and collection of samples. The bottom of this storage cylinder 15 is specially equipped with six independent storage compartments 16 for the safe and categorized storage of collected samples, named L1-L6 respectively. Each storage compartment 16 has a fixedly installed drive unit 17, the output end of which is fixedly connected to a push rod 18, and the end of the push rod 18 is fixedly installed with a push plate 19. Through the precise control of the drive unit 17, the push plate 19 can perform the pushing and releasing actions of the samples.
[0032] The auxiliary functional components include a metal frame 20 located at the front end of the metal cylinder 8. A high-brightness lighting device 21 is installed at the bottom of the metal frame 20, specifically designed to provide sufficient illumination for operations at night or in low-light conditions. Intelligent pump valves, a first intelligent pump valve 22 and a second intelligent pump valve 23, are symmetrically arranged at both ends of the metal frame 20. The first intelligent pump valve 22 is rigidly connected to the output end of a first motor 29 fixedly mounted on the metal frame 20, while the second intelligent pump valve 23 is rigidly connected to the output end of a second motor 30 also fixedly mounted on the metal frame 20. By precisely controlling the operation of the first motor 29 and the second motor 30 through the drive system, the first intelligent pump valve 22 and the second intelligent pump valve 23 can be rotated within a preset range (e.g., 0-180 degrees), thereby flexibly adjusting the injection angle of the two intelligent pump valves. A storage bin is fixedly installed on the lightweight chassis 2, and its internal space is divided into a first warehouse 24 and a second warehouse 25, respectively used to store different working media. A first discharge valve 26 is installed at the top of the first warehouse 24, and a second discharge valve 27 is installed at the top of the second warehouse 25. The first discharge valve 26 is connected to the first intelligent pump valve 22 via a detachable flexible hose, and the second discharge valve 27 is also connected to the second intelligent pump valve 23 via a detachable flexible hose. This design facilitates maintenance and replacement. Both the first intelligent pump valve 22 and the second intelligent pump valve 23 are equipped with precision metering nozzles 28 at their bottoms. These nozzles allow for the precise discharge of the medium stored in the first warehouse 24 and the second warehouse 25 to a designated directional area according to a preset quantity.
[0033] High-strength slide rails 31 are symmetrically arranged on both sides of the fixed frame 5. The slide rails 31 are slidably connected to the sliding support structure extending outward from the metal cylinder 8. This design allows the metal cylinder 8 to extend or retract smoothly along the axial direction of the fixed frame 5, thereby flexibly adjusting the working depth or position.
[0034] The entire system is powered by a drive system that not only supports the autonomous movement of the lightweight chassis 2 but also provides necessary power to all operating modules. The intelligent control system integrates automated monitoring and adjustment functions, enabling real-time monitoring of equipment status and operating parameters with intelligent feedback adjustments. The core function of the sample storage module is to safely preserve the collected samples, ensuring their integrity. Auxiliary components integrate additional equipment such as lighting, precise media delivery, and communication interfaces, significantly improving the overall operational efficiency and adaptability of the equipment in complex environments.
[0035] The drive system first activates the wheel structure 3, transmitting power through the transmission device to rotate the wheels, thereby propelling the entire lightweight frame 2 smoothly to the pre-set survey area, thus initiating the road survey task. Next, the drive system activates the hydraulic structure 7, which applies pressure through hydraulic cylinders, pushing the fixed frame 5 along the guide rail. The displacement of the fixed frame 5 causes the metal cylinder 8 to move forward synchronously, further displacing the inner cylinder 10. The advancement of the inner cylinder 10 causes the protective shell 11 to slide, and the movement of the protective shell 11 is transmitted to the drive structure 12. The drive structure 12, driven by this motion, precisely adjusts its position, positioning the drill rod 13 at the preset angle and survey area. Subsequently, the drive system directly controls the drive structure 12 to start operation. The drive structure 12 drives the drill rod 13 to rotate at high speed via an internal motor, and the drill rod 13 begins rotary drilling on the ground surface, achieving preliminary surveying.
[0036] Simultaneously, when drill rod 13 begins its rotation, the drive system coordinates the movement of metal cylinder 8, driving it to move steadily downwards along slide rail 31. Slide rail 31 provides vertical guidance, ensuring the precise descent trajectory of metal cylinder 8, thereby propelling drill rod 13 deeper into the ground for deep drilling operations. The coordinated rotation and downward movement of drill rod 13 effectively penetrates different strata, collecting underground soil or rock samples. These samples are extracted through the internal channels of drill rod 13, ultimately achieving a comprehensive geological exploration objective and providing data support for road construction. Throughout the process, the coordinated operation of all components ensures the efficiency and accuracy of the exploration operation.
[0037] During the drilling process of drill rod 13, the drive system starts and precisely controls the operation of telescopic rod 14. Through gradual extension, telescopic rod 14 effectively drives storage cylinder 15 to move stably towards the end of drill rod 13, ensuring that storage cylinder 15 moves synchronously with drill rod 13 throughout the drilling stroke, thereby avoiding positional deviations that could affect sampling accuracy. Based on the specific requirements of this geological or environmental sampling, the system presets the total sampling depth to H, and divides H into 6 independent segments, namely H1 to H6. H1 represents the shallowest layer closest to the ground, while H6 represents the deepest underground layer. Each depth layer from H1 to H6 is matched one-to-one with the corresponding storage chambers L1 to L6, ensuring a one-to-one correspondence between depth and storage unit.
[0038] When drill pipe 13 precisely reaches a designated depth layer (e.g., H1) during drilling, the drive system responds immediately, opening the matching storage chamber 16 via the intelligent control module. The opening mechanism is as follows: the drive system efficiently drives drive component 17, causing push rod 18 to retract smoothly inward, which in turn moves push plate 19 inward until push plate 19 is fully retracted into the storage chamber 16. At this point, the door of storage chamber 16 opens, forming an inlet state capable of containing media. For other storage chambers 16 that do not require media containment, the drive system maintains a strictly flush and locked state between push plate 19 and the door of storage chamber 16, forming a sealed barrier that prevents external media from entering, thereby isolating non-target sampling.
[0039] If, during the sampling process, some storage chambers 16 have successfully stored media (such as samples from previous depth layers), the continuous pressure applied by the drive system will efficiently compact the media within the storage chambers 16, forming a dense structure. This not only enhances sample integrity but also ensures that media from subsequent depth layers will not accidentally enter the already stored chambers, effectively preventing cross-contamination. This mechanism strictly guarantees that each storage chamber 16 can only store its matching specific depth layer media, achieving independent sampling at different layers.
[0040] When the drive system drives drill rod 13 to drill to depth H1, the system intelligently pauses the operation of drill rod 13 to avoid excessive drilling interference. Simultaneously, the drive system continues to drive telescopic rod 14, pushing storage cylinder 15 downwards until its bottom is firmly pressed against the surface of the medium in depth H1. Subsequently, the drive system continues to apply pressure, and through the stable operation of telescopic rod 14, the medium in depth H1 is compressed and smoothly enters the opened storage chamber 16, completing sample collection. For other depths (such as H2 to H6), the drive system strictly follows the above procedure: the drill rod pauses after reaching the target depth, and the telescopic rod drives the storage cylinder to compress the medium and enter the matching storage chamber, ensuring that the medium in each depth is efficiently and accurately sampled and stored, achieving fully automated control of the entire process.
[0041] The first storage bin 24 stores fine sand, which is continuously released into the drilling area during the operation of drill rod 13 to prevent the ground drilling area from sinking due to drilling. The second storage bin 25 flexibly stores media according to the ground conditions: if the ground is frozen, defreezing agent is pre-stored to thaw the frozen soil; if the ground is at normal temperature, diluent is pre-stored to soften the loose soil. Both the diluent and the defreezing agent reduce the ground hardness through dilution, thereby increasing the drilling speed of drill rod 13. All media adopt a fixed-frequency and quantitative release mechanism to ensure that the release process is stable and controllable. The operation process of the second storage bin 25 is as follows: the drive system first drives the pump in the bin to add media. The medium is pressurized and conveyed to the second discharge valve 27. The medium then enters the elastic hose through the second discharge valve 27 for flexible transmission. It is then conveyed through the elastic hose to the second intelligent pump valve 23 for precise control. Finally, it is released to the target area at a preset rate through the metering nozzle 28. The operation process of the first warehouse 24 is similar. The drive system drives the pump in the warehouse to push the fine sand to the first discharge valve 26. The medium flows into the elastic hose through the first discharge valve 26 to ensure smooth flow. Then, it is guided by the elastic hose to the first intelligent pump valve 22 for adjustment. Finally, it is evenly sprayed to the drilling area by the metering nozzle 28. This design ensures the high efficiency and reliability of the entire system.
