Description

Technical Field

[0002] Sampling in road engineering is a crucial step in ensuring the quality of road projects. Road engineering refers to the entire process of planning, designing, constructing, maintaining, and managing roads, as well as the physical engineering entities involved. To ensure the safety of completed, under-construction, and planned building projects, it is an important task to test the foundation, building materials, construction techniques, and building structure related to the buildings throughout the construction process. During use, structures will deform under load. Before and after road engineering is put into use, as well as at different stages during use, testing is often required to ensure safe production or to understand the safety and reliability of the structure, providing a reliable scientific basis for making various decisions and plans.

Positioning the sampling equipment is difficult, and overall shaking and vibration affect the sampling process. This makes operation challenging for the operator. Furthermore, the sampling equipment cannot meet reliable sampling benchmarks in either the horizontal or vertical directions of the road surface, resulting in poor sampling reliability, poor operability, and difficulty in providing stable support on complex road surfaces, making sampling work difficult.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0029] like Figure 1 , Figure 2 As shown, Figure 1 This is a schematic diagram of the detection and sampling system provided in the embodiments of this application. Figure 2 This is a top view of a testing and sampling system provided in an embodiment of this application. The system, a road engineering testing and sampling system, includes a main body 100, a sampling component 200, and a positioning component 400, wherein:

[0030] like Figure 1 , Figure 2As shown, the main body 100 is provided with a work platform, and the work platform is provided with a through sampling hole 101. The main body 100 is the basic structure of the entire detection sampling system, and provides a stable platform for supporting and operating other components.

[0031] The main body 100 is provided with a work platform, which is a working area for sampling operation. The work platform has enough space to accommodate necessary equipment. The work platform is provided with a through sampling hole 101 to provide space for the sampling member 200 to pass through, so that the sampling member 200 arranged on the main body 100 extends to the work area for sampling operation.

[0032] The sampling member 200 is movably connected with the main body 100 and arranged on the work platform. One end of the sampling member 200 can be extended through the sampling hole 101.

[0033] As shown in Figure 1 , Figure 2 The sampling member 200 is used to directly contact the road surface and perform sampling. The sampling member 200 is movably connected with the main body 100 and can move relatively on the work platform. The sampling member 200 passes through the sampling hole 101 on the work platform by displacement relative to the main body 100, and penetrates into the road surface in the work area for sampling. The sampling member 200 can include a drill bit, a cutting tool or other suitable sampling tools for road surface materials, which can be replaced or adjusted according to different road surface materials and sampling requirements.

[0034] As shown in Figure 1 , Figure 2 The positioning member 400 is provided with a plurality of positioning members 400, each of which has a first end for being inserted into the work area. The positioning member 400 is rotatably connected with the main body 100, so that a plurality of positioning members 400 can be rotatably inserted into the work area at different angles.

[0035] The positioning member 400 is used to fix the target position of the main body 100 in the work area. The positioning member 400 is provided with a plurality of positioning members 400 to ensure that the main body 100 can stably work at different positions and angles.

[0036] Each positioning member 400 has a first end for being inserted into the work area, which allows the positioning member 400 to be fixed on the work area to prevent the main body 100 from moving or tilting during sampling.

[0037] The positioning member 400 is rotatably connected with the main body member 100, so as to design to allow the operator to adjust the angle of the positioning member 400 according to the specific conditions of the working area, so as to achieve the best fixing effect. Considering the flexibility and adaptability of operation, efficient and accurate sampling work can be carried out under different road conditions. Since the insertion direction of the positioning member 400 is the direction after the rotation of the positioning member 400, after the first end of the positioning member 400 is inserted on the working area, the pulling-out directions of the positioning members 400 with different angles are inconsistent, further, the main body member 100 is limited by the positioning members 400, and the pulling-out direction of the positioning member 400 is also not parallel to the displacement direction of the sampling member 200, further providing a stable resistance basis, facilitating the displacement of the sampling member 200 towards the sampling area, avoiding the positioning member 400 being pushed out of the working area during the operation, and avoiding the loosening of the insertion state of the positioning member 400, greatly improving the stability.

[0038] The working platform on the main body member 100 provides a stable operating environment, making the entire sampling process safer and more convenient. This system can be widely used in road construction, maintenance and quality detection fields, and provides scientific and accurate data support for pavement engineering.

[0039] In an optional embodiment, the working principle of the road engineering detection sampling system in the application is that the detection sampling system comprises a main body 100, a sampling member 200, and positioning members 400. The main body 100 is provided with a working platform. The working platform is provided with a through sampling hole 101. The sampling member 200 is movably connected with the main body 100 and arranged on the working platform. One end of the sampling member 200 can be telescopically inserted through the sampling hole 101. The positioning members 400 are provided in plurality. Each of the positioning members 400 has a first end for being inserted into a working area. The positioning members 400 are rotatably connected with the main body 100, so that the plurality of positioning members 400 can be rotatably inserted into the working area at different angles. In actual operation, the main body 100 supports the sampling member 200 and the positioning members 400 to a sampling area. The positioning of the main body 100 is realized by inserting the first ends of the positioning members 400 into the working area. The plurality of positioning members 400 can be rotated according to the road conditions of the working area. When the plurality of positioning members 400 are rotated to different angles, the first ends of the positioning members 400 are inserted into the working area at different angles to form stable positioning of the main body 100. The detection sampling system as a whole can be stably positioned in the horizontal direction and the vertical direction of the working area by the positioning members 400 at different angles, effectively preventing the forward, backward, leftward, and rightward sliding of the main body 100. The displacement of the main body 100 in the vertical direction caused by the reaction force of the sampling member 200 during sampling operation is also avoided. The sampling member 200 can always perform sampling operation based on the reliable working foundation of the main body 100, improving the operation reliability and reducing the labor intensity of the operator. Especially in the face of complex working conditions, the positioning members 400 can be rotated to adapt to the working conditions of the road engineering and adaptively perform positioning operation of the detection sampling system as a whole by reliable positioning points, which is more operable.

[0040] As shown in Figure 1 , Figure 3 and Figure 4 , Figure 3 the accompanying drawings provided by the embodiments of the application, Figure 2 the sectional view at A-A, Figure 4 the accompanying drawings provided by the embodiments of the application, Figure 3 the sectional view at B-B; in an optional embodiment, the positioning member 400 comprises a first positioning part 401 and a second positioning part 402. The second positioning part 402 is provided through the first positioning part 401 and can reciprocally move along the axial direction of the first positioning part 401. The first positioning part 401 is rotatably connected with the main body 100. The end of the second positioning part 402 is in inverted conical shape.

[0041] As shown in Figure 3 andFigure 4 As shown, the first positioning part 401 is connected to the main body 100 and provides support, and an axial channel is provided in the first positioning part 401 to allow the second positioning part 402 to reciprocate along the axial direction of the first positioning part 401, so that the positioning part 400 can adapt to different working depths and road conditions.

[0042] As shown in Figure 3 and Figure 4 The second positioning part 402 is a movable part of the positioning part 400, and the second positioning part 402 is arranged through the first positioning part 401 and can reciprocate along the axis of the first positioning part 401 as needed. The end of the second positioning part 402 is designed as an inverted cone, which helps to reduce resistance when inserted into the road surface.

[0043] The connection between the first positioning part 401 and the main body 100 is rotatable, allowing the operator to adjust the angle of the positioning part 400 according to the specific conditions of the working area to achieve the best fixing effect. The rotatable connection provides flexibility, allowing the positioning part 400 to adapt to different road angles and terrain, ensuring that the main body 100 can work stably under various conditions.

[0044] In use, the operator can adjust the angle of the first positioning part 401 according to the specific conditions of the road surface, and then insert the second positioning part 402 into the road surface until the desired depth is reached. Once the positioning part 400 is fixed on the road surface, the main body 100 can be stably placed in the working area for sampling operation.

[0045] After sampling is completed, the second positioning part 402 can be removed from the road surface, and the positioning part 400 can be adjusted to a new position, or the entire system can be moved to the next working point. Through the cooperation of the first positioning part 401 and the second positioning part 402, a stable and flexible fixing system is provided, allowing the road engineering detection sampling system to efficiently and accurately complete the sampling task in a variable working environment.

[0046] As shown in Figure 1 and Figure 2 In an optional embodiment, a plurality of positioning holes 102 matching the positioning part 400 are provided on the main body 100, and a rotating shaft 103 connecting the positioning part 400 is provided in each positioning hole 102. The intersection of the center lines of each rotating shaft 103 coincides with the center point of the main body 100.

[0047] The main body 100 is provided with a plurality of positioning holes 102 matched with the positioning members 400. The size and shape of the plurality of positioning holes 102 are matched with the positioning members 400, ensuring that the positioning members 400 can be stably fixed on the main body 100. The number and position of the positioning holes 102 are determined according to the size of the main body 100 and the operation requirements, to ensure that effective support can be provided in different operation areas and angles.

[0048] As shown in Figure 2 , Figure 3 and Figure 4 , each positioning hole 102 is provided with a rotating shaft 103, which is used to connect and fix the positioning member 400, so that it can be rotatably connected with the main body 100. The design of the rotating shaft 103 allows the positioning member 400 to rotate in the positioning hole 102 to adapt to different operation angles and road conditions.

[0049] The extension lines of the center lines of each rotating shaft 103 intersect at a point, which coincides with the center point of the main body 100. This ensures that the main body 100 can maintain balance and stability under the support of multiple positioning members 400, especially when operating on uneven ground or complex terrain. Since the center lines of the rotating shafts 103 intersect at the center point of the main body 100, the operator can easily adjust the angle of the positioning member 400 without worrying about the stability of the main body 100. This simplifies the operation process and improves the operation efficiency, especially when the positioning member 400 needs to be quickly adjusted to adapt to different operation conditions.

[0050] This makes the road engineering detection and sampling system able to efficiently and accurately complete the sampling task under various conditions.

[0051] As shown in Figure 3 and Figure 4 , in an optional embodiment, the first positioning part 401 and the second positioning part 402 are coaxially arranged, and the rotating shaft 103 penetrates the first positioning part 401 and the second positioning part 402 at the same time. The second positioning part 402 is provided with a strip-shaped groove 403, and the rotating shaft 103 is arranged in the strip-shaped groove 403.

[0052] Specifically, the first positioning part 401 and the second positioning part 402 are coaxially arranged, and share the same axis, which helps to maintain the stability and consistency of the positioning member 400. The coaxial arrangement ensures the synchronization of the first positioning part 401 and the second positioning part 402 during rotation and movement, thereby improving the response speed of the entire system and the accuracy of the operation.

[0053] The rotating shaft 103 passes through the first positioning part 401 and the second positioning part 402 at the same time, so that the two parts can rotate and move as a whole. The rotating shaft 103 is arranged to pass through to allow the first positioning part 401 and the second positioning part 402 to rotate freely within the positioning hole 102 of the main body 100 while maintaining the relative position between them.

[0054] The second positioning part 402 is provided with a throughly arranged strip-shaped slot 403 to allow the rotating shaft 103 to move relatively in the strip-shaped slot 403, providing the second positioning part 402 with the ability to move back and forth along the axis of the rotating shaft 103. The strip-shaped slot 403 ensures the stability of the rotating shaft 103 and allows the second positioning part 402 to be adjusted when needed to adapt to different working depths.

[0055] The rotating shaft 103 is arranged in the strip-shaped slot 403, and the second positioning part 402 can move flexibly on the rotating shaft 103 while maintaining the connection with the rotating shaft 103. It allows the second positioning part 402 to be fine-tuned when inserted into the road surface or taken out to ensure the best fixing effect and minimum insertion resistance.

[0056] Thanks to the cooperation of the rotating shaft 103 and the strip-shaped slot 403, the operator can easily adjust the position of the second positioning part 402 to adapt to different working conditions and road surface conditions. The positioning part 400 can be quickly adjusted to meet different working requirements. It ensures the stability and accuracy of the positioning part 400 during operation.

[0057] As shown in Figure 1 , Figure 3 and Figure 4 , in an optional embodiment, the sampling part 200 includes a sampling cylinder 201, and a driving part is arranged between the sampling cylinder 201 and the main body 100, which is used to drive the sampling cylinder 201 to move up and down in the sampling hole 101 and to rotate.

[0058] Specifically, the sampling cylinder 201 directly contacts the road surface and samples. The driving part connects the sampling cylinder 201 and the main body 100, and is responsible for driving the sampling cylinder 201 to move up and down and rotate in the sampling hole 101.

[0059] The driving part can be an electric, pneumatic or hydraulic drive system, and the specific choice depends on the design requirements and operating environment of the system.

[0060] The driving part is used to drive the sampling cylinder 201 to move up and down in the sampling hole 101, which allows the sampling cylinder 201 to sample to different depths. The up and down movement function allows the sampling cylinder 201 to accurately reach the predetermined sampling position, improving the accuracy and efficiency of sampling.

[0061] In addition to the lifting movement, the driving member is also used to drive the sampling cylinder 201 to rotate. The rotating function can help the sampling cylinder 201 to penetrate the road surface better, especially in hard or mixed road surface materials. The rotation can increase the success rate of sampling.

[0062] As shown in Figure 1 , Figure 3 and Figure 4 , in an optional embodiment, the sampling member 200 further comprises an intermediate plate 202, and the driving member comprises a first driving part 204 and a second driving part 205. The first driving part 204 is arranged between the main body member 100 and the intermediate plate 202 and is used to push and pull the intermediate plate 202 to move reciprocally. The second driving part 205 is arranged between the intermediate plate 202 and the sampling cylinder 201 and is used to drive the sampling cylinder 201 to rotate.

[0063] The intermediate plate 202 connects the main body member 100 and the sampling cylinder 201 and provides a stable foundation for transmitting driving force. The first driving part 204 is arranged between the main body member 100 and the intermediate plate 202 to push the intermediate plate 202 to move reciprocally. The reciprocating movement of the intermediate plate 202 makes the sampling cylinder 201 extend or retract from the main body member 100 to adapt to different sampling depths and positions. The first driving part 204 can be an electric push rod, a pneumatic cylinder or a hydraulic cylinder, and the specific selection depends on the required force and speed.

[0064] The second driving part 205 is arranged between the intermediate plate 202 and the sampling cylinder 201 to drive the sampling cylinder 201 to rotate. The second driving part 205 can be an electric motor, a pneumatic motor or a hydraulic motor, and the specific selection depends on the required torque and speed.

[0065] The first driving part 204 and the second driving part 205 work together to achieve precise positioning and rotation of the sampling cylinder 201. This coordinated work can be achieved through a precise control system such as a PLC (Programmable Logic Controller) or a microcontroller to ensure the accuracy and response speed of the operation.

[0066] Through independent control of the first driving part 204 and the second driving part 205, the operator can easily control the movement and rotation of the sampling cylinder 201, improving the work efficiency.

[0067] As shown in Figure 1 , Figure 3 and Figure 4As shown, in an optional embodiment, a plurality of guide rods 104 are fixed on the main body 100, the guide rods 104 are arranged in parallel and at intervals, a top plate 105 is fixed on the top of the guide rods 104, the first driving part 204 is arranged between the top plate 105 and the intermediate plate 202, and a plurality of clamping grooves 203 corresponding to the guide rods 104 are arranged on the intermediate plate 202, and the guide rods 104 are clamped in the clamping grooves 203.

[0068] The guide rods 104 are fixed on the main body 100, the guide rods 104 are arranged in parallel and at intervals, and the guide rods 104 provide accurate guidance for the sampling part 200. The top of the guide rod 104 is fixed with the top plate 105, which serves as the mounting platform of the first driving part 204, and improves the relative stability of the plurality of guide rods 104,

[0069] The first driving part 204 is arranged between the top plate 105 and the intermediate plate 202, and pushes the intermediate plate 202 to move back and forth. The intermediate plate 202 is provided with a plurality of clamping grooves 203, and the clamping grooves 203 correspond to the guide rods 104 one by one, which are used for relative guiding and fixing.

[0070] The clamping grooves 203 ensure that the guide rods 104 can be stably clamped in the clamping grooves 203, reducing the deviation during movement. The guide rods 104 are clamped in the clamping grooves 203, so that the intermediate plate 202 can move back and forth accurately under the guidance of the guide rods 104, ensuring the accurate positioning of the sampling cylinder 201 during sampling.

[0071] As shown in FIG. 1, Figure 4 and Figure 5 As shown, Figure 5 the cross-sectional view of the positioning groove 302 in the connecting cover 301 provided by the embodiment of the application, in an optional embodiment, a connecting cover 301 is arranged between the second driving part 205 and the sampling cylinder 201, the output end of the second driving part 205 is fixedly connected to the connecting cover 301, and the sampling cylinder 201 is detachably fixedly connected to the connecting cover 301.

[0072] The connecting cover 301 serves as an intermediate structure between the second driving part 205 and the sampling cylinder 201, and is used to transmit the rotating power of the second driving part 205 to the sampling cylinder 201.

[0073] The output end of the second driving part 205 is fixedly connected to the connecting cover 301, and the fixed connection can be bolted, welded or other mechanical connection.
