Description

Technical Field

[0001] The present invention relates to the technical field of detection sampling, and more specifically, to a road detection sampling device. Background Art

[0002] The road inspection sampling device is an important device used to sample and inspect road pavement materials during the construction of highways or urban roads. It refers to the inspection of the quality of the construction road. It is mainly used to evaluate the quality and performance of the road surface, ensure that the road project meets the design and safety standards, ensure that the strength and quality of the road can meet the construction requirements and traffic requirements, and improve the safety and durability of the road.

[0003] In seasonally frozen areas, when the temperature drops suddenly, the moisture under the road surface freezes quickly, increasing the adhesion between the soil and the road surface. The physical properties of the soil will change during the freezing process, such as volume expansion and increased density. These changes will cause the contact between the soil and the road surface to become closer, making it easier for the soil and the bottom layer of the cement road to freeze together. This will cause the bottom wall of the sample to freeze tightly to the ground during sampling, that is, the soil and the bottom layer of the cement road are frozen together. When the soil and the sample are frozen together, it is more difficult to remove the sample.

[0004] Therefore, a road detection sampling device is proposed. Summary of the invention

[0005] In view of the problems existing in the prior art, the object of the present invention is to provide a road detection sampling device, which can separate the sample from the soil after the sampling is completed, so as to facilitate the removal of the sample.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A road detection sampling device comprises a bracket, a hydraulic rod is mounted on the bracket, and a mounting frame is mounted on the output end of the hydraulic rod;

[0008] A motor is fixedly mounted on the mounting frame, a drill barrel is arranged on the output end of the motor, a magnetic coupling is fixedly mounted on the mounting frame, the output end of the motor is connected to the driving shaft of the magnetic coupling, and the drill barrel is mounted on the output end of the magnetic coupling; by arranging the magnetic coupling, the motor can be protected when the drill barrel is blocked and cannot rotate, thereby preventing the motor from burning out; arc grooves are evenly arranged on the inner side wall of the drill barrel, a mounting rod is vertically rotatably mounted in the arc groove, a spring is arranged between the mounting rod and the top wall of the arc groove, an arc-shaped cutting knife is sleeved on the mounting rod, and a rotating assembly cooperating with the mounting rod is arranged on the drill barrel;

[0009] A spring telescopic rod is fixedly installed on the inner top wall of the drill tube, a pressure plate is rotatably installed on the output end of the spring telescopic rod, and the diameter of the inner wall of the drill tube gradually increases from bottom to top, and an anti-stuck component cooperating with the cutting knife is provided on the drill tube;

[0010] An air inlet hole is opened on the top wall of the drill barrel, and blades are evenly fixed on the outer wall of the spring telescopic rod. The blades are used to drive the air flow downward. An exhaust hole is opened on the side wall of the drill barrel, and the exhaust hole is located below the arc groove. The diameter of the outer wall of the drill barrel gradually decreases from bottom to top.

[0011] The rotating assembly includes a slide groove provided on the top wall of the arc groove, and a magnetic block is slidably installed in the slide groove. By providing the slide groove on the top wall of the arc groove, impurities can be prevented from falling into the slide groove, ensuring that the magnetic block can move freely in the slide groove. An elastic rope is installed between the side wall of the arc groove close to the mounting rod and the magnetic block.

[0012] A moving magnet is fixedly installed on one end of the cutting knife away from the mounting rod, and a fixed magnet is embedded in the arc groove. The fixed magnet and the moving magnet attract each other, and the magnetic block and the moving magnet repel each other, and the repulsive force between the magnetic block and the moving magnet is greater than the attractive force between the fixed magnet and the moving magnet. A limiting rod cooperating with the cutting knife is fixedly installed in the arc groove. The limiting rod prevents the moving magnet and the fixed magnet from being adsorbed together, thereby ensuring that the magnetic block can move to the space between the moving magnet and the fixed magnet.

[0013] Furthermore, the anti-stuck component includes a guide channel opened on the drill tube, and an annular groove cooperating with the blade is opened on the side wall of the drill tube, and the airflow impacting the top wall of the sample changes direction and enters the annular groove, and the top of the guide channel is located at the bottom wall of the annular groove;

[0014] An inclined groove is provided on the mounting rod, and the lateral inclination angle of the inclined groove is 60°-70°. The bottom end of the guide channel cooperates with the inclined groove, and the top end of the exhaust hole is located on the bottom wall of the arc groove. The gas discharged from the bottom end of the guide channel is used to impact the side wall of the inclined groove, thereby causing the mounting rod to rotate, and a sealing plate that cooperates with the air inlet hole is fixedly installed on the mounting frame.

[0015] Furthermore, two cutting knives are provided on the mounting rod, and two cutting slits can be formed on the frozen soil by the two cutting knives. A scraper made of elastic material is fixedly mounted on the mounting rod, and the scraper is located between the two cutting knives. As the mounting rod rotates, the scraper contacts the flaky frozen soil between the two slits. At this time, the frozen soil is gradually consumed due to friction, which can gradually reduce the volume of the flaky frozen soil, and the scraped debris is in a loose state, thereby preventing the cutting knife from being stuck, further improving the anti-stuck effect of the cutting knife.

[0016] Furthermore, a hole is provided on the pressure plate, and the bottom end of the spring telescopic rod is located outside the drill tube.

[0017] Furthermore, the hole is funnel-shaped, and the diameter of the hole gradually decreases from bottom to top. An elastic member is fixedly installed in the hole, and a spoiler is fixedly installed on the elastic member.

[0018] Furthermore, the bracket is equipped with supporting legs, an image acquisition module, a judgment module and an alarm module; the judgment module is used to judge the position of the supporting legs, and the alarm module is used to issue an alarm.

[0019] Furthermore, a spray paint bottle is detachably mounted on the supporting leg, and the spray paint bottle is used to spray marks on the ground.

[0020] Furthermore, a protective cover is provided on the movable sleeve of the supporting leg, the protective cover cooperates with the bottom end of the supporting leg, the protective cover is made of metal, and a magnetic plate cooperating with the protective cover is installed on the bracket.

[0021] Furthermore, the entire device is first placed at a designated location, and then a worker takes a spray paint bottle and sprays a sampling mark on the ground directly below the image acquisition module. The image acquisition module is used to capture the position of the support leg and the ground mark, and processes the collected information and then sends it to the judgment module.

[0022] The judgment module is used to judge the distance between the real-time position and the initial position of the support leg and the ground mark, and send the result to the alarm module;

[0023] when ;

[0024] The alarm module sounds an alarm to inform the staff that the device position has shifted;

[0025] when ;

[0026] The alarm module does not work;

[0027] Wherein, D is the initial distance between the bottom wall edge of the supporting leg and the edge of the mark, and d is the real-time distance between the bottom wall edge of the supporting leg and the edge of the mark.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) This scheme is provided with a cutting knife and a rotating assembly; after the sampling is completed, the motor is reversed to make the cutting knife tend to rotate out of the arc groove, thereby cutting off the frozen soil, thereby facilitating the removal of the sample. At the same time, the extended cutting knife can provide support for the sample and soil above the cutting knife, thereby ensuring that the sample can be taken out of the sampling hole along with the drill tube;

[0030] (2) This solution can heat the frozen soil in the cutting blade and the drill tube by setting a pressure plate, a spring telescopic rod, and a blade, thereby improving the cutting effect of the cutting blade on the frozen soil and improving work efficiency;

[0031] (3) This solution allows the air inlet to intermittently move to the bottom of the blocking plate, so that the cutting knife can intermittently contact the soil during operation, preventing the cutting knife from getting stuck in the soil, thereby protecting the cutting knife. At the same time, the cutting knife intermittently hits the soil, which can improve the cutting effect on the soil through the impact force, further improving work efficiency.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0045] Example 1: Please refer to Figures 1 to 10 , a road detection sampling device, comprising a bracket 1, a hydraulic rod 2 is mounted on the bracket 1, and a mounting frame 3 is mounted on the output end of the hydraulic rod 2;

[0046] A motor 4 is fixedly mounted on the mounting frame 3, a drill tube 5 is arranged on the output end of the motor 4, a magnetic coupling 6 is fixedly mounted on the mounting frame 3, the output end of the motor 4 is connected to the driving shaft of the magnetic coupling 6, and the drill tube 5 is mounted on the output end of the magnetic coupling 6; by arranging the magnetic coupling 6, the motor 4 can be protected when the drill tube 5 is blocked and cannot rotate, so as to prevent the motor 4 from burning out, arc grooves 7 are evenly arranged on the inner side wall of the drill tube 5, a mounting rod 8 is vertically rotatably mounted in the arc groove 7, a clockwork 9 is arranged between the mounting rod 8 and the top wall of the arc groove 7, an arc-shaped cutting knife 10 is sleeved on the mounting rod 8, and a rotating assembly cooperating with the mounting rod 8 is arranged on the drill tube 5;

[0047] A spring telescopic rod 11 is fixedly mounted on the inner top wall of the drill tube 5, a pressing plate 12 is rotatably mounted on the output end of the spring telescopic rod 11, and the diameter of the inner wall of the drill tube 5 gradually increases from bottom to top, and an anti-stuck component cooperating with the cutting knife 10 is provided on the drill tube 5;

[0048] An air inlet 13 is provided on the top wall of the drill tube 5, and blades 14 are evenly fixedly installed on the outer wall of the spring telescopic rod 11. The blades 14 are used to drive the air flow downward. An exhaust hole 15 is provided on the side wall of the drill tube 5. The exhaust hole 15 is located below the arc groove 7, and the diameter of the outer wall of the drill tube 5 gradually decreases from bottom to top.

[0049] The rotating assembly includes a slide groove 16 provided on the top wall of the arc groove 7, and a magnetic block 17 is slidably installed in the slide groove 16. By providing the slide groove 16 on the top wall of the arc groove 7, impurities can be prevented from falling into the slide groove 16, ensuring that the magnetic block 17 can move freely in the slide groove 16. An elastic rope 18 is installed between the side wall of the arc groove 7 close to the mounting rod 8 and the magnetic block 17.

[0050] A moving magnet 19 is fixedly installed at one end of the cutting knife 10 away from the mounting rod 8, and a fixed magnet 20 is embedded in the arc groove 7. The fixed magnet 20 and the moving magnet 19 attract each other, and the magnetic block 17 and the moving magnet 19 repel each other, and the repulsive force between the magnetic block 17 and the moving magnet 19 is greater than the attractive force between the fixed magnet 20 and the moving magnet 19, and a limiting rod 21 cooperating with the cutting knife 10 is fixedly installed in the arc groove 7. The limiting rod 21 prevents the moving magnet 19 and the fixed magnet 20 from being adsorbed together, thereby ensuring that the magnetic block 17 can move to the space between the moving magnet 19 and the fixed magnet 20.

[0051] First, the bracket 1 is placed on the ground so that the drill tube 5 is located above the sampling position; at this time, under the action of the elastic rope 18, the magnetic block 17 is away from the fixed magnet 20, and under the action of the spring 9, the cutting knife 10 is located in the arc groove 7.

[0052] During the sampling process, the motor 4 is started, and the motor 4 drives the driving shaft of the magnetic coupling 6 to rotate, so the drill tube 5 installed on the output end of the magnetic coupling 6 also rotates. At the same time, downward pressure is applied to the bracket 1, and the hydraulic rod 2 is started, so that the drill tube 5 can gradually drill into the ground, and the sample gradually enters the drill tube 5. Among them, the sampling of the drill tube 5 driven by the motor 4 is a prior art and will not be repeated. By setting the pressure plate 12 and the spring telescopic rod 11, downward pressure can be applied to the sample during the sampling process to prevent the sample from shaking, that is, the side wall of the sample is prevented from contacting the inner wall of the drill tube 5 during the downward movement of the drill tube 5, which prevents the top of the sample side wall from entering the arc groove 7 and causing damage to the cutting knife 10.

[0053] When the drill tube 5 reaches the specified depth, the motor 4 is controlled to rotate in the reverse direction.

[0054] When the drill tube 5 rotates toward the mounting rod 8 in the direction close to the fixed magnet 20, under the combined action of inertia and the elastic rope 18, the magnetic block 17 is located at one end of the slide groove 16 close to the mounting rod 8. At this time, under the action of the attraction between the fixed magnet 20 and the moving magnet 19, the cutting knife 10 is located in the arc groove 7, and the drill tube 5 can move downward normally.

[0055] When the drill barrel 5 rotates in the direction of the mounting rod 8 away from the fixed magnet 20, the magnetic block 17 moves along the slide groove 16 under the action of inertia. Due to the gap between the cutting knife 10 and the moving magnet 19 under the action of the limit rod 21, the magnetic block 17 finally moves to the position between the moving magnet 19 and the fixed magnet 20. At this time, under the action of the repulsive force between the magnetic block 17 and the moving magnet 19, the moving magnet 19 has a tendency to move away from the arc groove 7. Therefore, the cutting knife 10 drives the mounting rod 8 to rotate, and the cutting knife 10 is rotated out of the arc groove 7 and can contact the frozen soil in the drill barrel 5. Under the action of the repulsive force, the cutting knife 10 is always in contact with the frozen soil. Therefore, in the process of the drill barrel 5 driving the cutting knife 10 to rotate, the frozen soil inside the drill barrel 5 can be separated from the ground soil, which makes it easier for the sample to be taken out of the borehole together with the drill barrel 5.

[0056] When the cutting is completed, the hydraulic rod 2 contracts and the drill tube 5 moves upward. Since the sample tends to fall downward under the action of gravity, the cutting knife 10 is unable to retract into the arc groove 7 due to the large friction force. At this time, the cutting knife 10 can lift the sample, thereby ensuring that the sample can move with the drill tube 5.

[0057] After the drill tube 5 is taken out from the borehole, the drill tube 5 is laid flat to reduce the friction force on the cutting knife 10. At this time, the elastic rope 18 pulls the magnetic block 17 to reset, so that the cutting knife 10 can be rotated back to the arc groove 7, which makes it easier to take out the sample.

[0058] And during the rotation of the drill tube 5, the blades 14 are driven to rotate by the spring telescopic rod 11. At this time, the blades 14 squeeze the air downward, so the drill tube 5 is exhausted downward; that is, the drill tube 5 inhales air through the air inlet 13 and exhausts air through the exhaust hole 15, so the inside of the drill tube 5 can achieve airflow exchange with the outside world.

[0059] In the process of fixing the sample by the pressing plate 12, the output end of the spring telescopic rod 11 and the pressing plate 12 rub against each other and generate heat. Therefore, in the process of downward movement of the airflow, the pressing plate 12 and the output end of the spring telescopic rod 11 can be cooled to prevent the spring telescopic rod 11 and the pressing plate 12 from expanding due to heat, thereby extending the service life of the spring telescopic rod 11 and the pressing plate 12.

[0060] At the same time, the airflow that absorbs the heat flows downward, thereby heating the cutting blade 10 and the frozen soil, thereby assisting the cutting blade 10 in cutting the soil and improving the cutting effect on the frozen soil.

[0061] like Figure 4 , Figure 5 , Fig. 9As shown, the anti-stuck component includes a guide channel 22 opened on the drill tube 5, and an annular groove cooperating with the blade 14 is opened on the side wall of the drill tube 5. The airflow impacting the top wall of the sample changes direction and enters the annular groove. The top of the guide channel 22 is located at the bottom wall of the annular groove;

[0062] An inclined groove 23 is provided on the mounting rod 8, and the lateral inclination angle of the inclined groove 23 is 60°-70°. The bottom end of the guide channel 22 cooperates with the inclined groove 23, and the top end of the exhaust hole 15 is located on the bottom wall of the arc groove 7. The gas discharged from the bottom end of the guide channel 22 is used to impact the side wall of the inclined groove 23, thereby causing the mounting rod 8 to rotate, and a sealing plate 24 that cooperates with the air inlet hole 13 is fixedly installed on the mounting frame 3.

[0063] By adopting the above technical solution, during the rotation of the blades 14, the gas squeezed by the blades 14 enters the guide channel 22. At this time, the gas discharged from the guide channel 22 impacts the side wall of the chute 23, thereby forcing the mounting rod 8 to reverse and causing the cutting knife 10 to break contact with the frozen soil.

[0064] During the rotation of the drill barrel 5, the air inlet 13 intermittently moves to the bottom of the sealing plate 24, and when the sealing plate 24 moves to the bottom of the air inlet 13 to block the air inlet 13, the gas in the drill barrel 5 cannot flow quickly. At this time, the gas discharged from the diversion channel 22 will not be able to continue to impact the mounting rod 8 to rotate. Therefore, under the action of the magnetic block 17 and the moving magnet 19, the cutting knife 10 contacts the soil again.

[0065] Therefore, during the working process, the cutting knife 10 can be intermittently in contact with the soil to prevent the cutting knife 10 from being stuck in the soil, thereby protecting the cutting knife 10. At the same time, the cutting knife 10 intermittently hits the soil, which can improve the cutting effect on the soil through the impact force, thereby further improving the working efficiency.

[0066] like Fig. 9 As shown, two cutting knives 10 are provided on the mounting rod 8, and two slits can be cut on the frozen soil by the two cutting knives 10. A scraper 25 made of elastic material is fixedly installed on the mounting rod 8, and the scraper 25 is located between the two cutting knives 10. As the mounting rod 8 rotates, the scraper 25 contacts the flaky frozen soil between the two slits. At this time, the frozen soil between the two cutting knives 10 is gradually consumed due to friction, which can gradually reduce the volume of the flaky frozen soil, and the scraped debris is in a loose state, thereby preventing the cutting knife 10 from being stuck, further improving the anti-stuck effect of the cutting knife 10.

[0067] like Figure 4 , Figure 7 As shown, a hole 26 is opened on the pressing plate 12, and the bottom end of the spring telescopic rod 11 is located outside the drill tube 5.

[0068] By adopting the above technical solution, before the drill barrel 5 contacts the ground, the drill barrel 5 is already in a rotating state. At this time, the airflow generated under the blade 14 passes through the hole 26 to impact the ground. At this time, the bottom wall of the drill barrel 5 does not contact the ground, so that the impurities on the surface of the ground to be sampled can be cleaned up by the impact force, ensuring that the pressure plate 12 can fit the ground, thereby preventing the sampling part from shaking during the sampling process, and preventing the edge of the top wall of the sampling part from entering the arc groove 7 during the downward movement of the drill barrel 5, thereby protecting the cutting knife 10.

[0069] like Figure 7 As shown, by adopting the above technical solution, the hole 26 is funnel-shaped, and the diameter of the hole 26 gradually decreases from bottom to top. An elastic member 27 is fixedly installed in the hole 26, and a spoiler 28 is fixedly installed on the elastic member 27.

[0070] When the airflow passes through the hole 26, the airflow impacts the spoiler block 28. At this time, the spoiler block 28 shakes, thereby changing the direction of the airflow discharged from the hole 26, increasing the contact area between the airflow and the ground to be sampled, improving the cleaning effect of the ground, and ensuring that the pressure plate 12 can fit the ground.

[0071] like Figure 3 As shown, by adopting the above technical solution, the bracket 1 is installed with a supporting leg 29, an image acquisition module 30, a judgment module 31 and an alarm module 32; the judgment module 31 is used to judge the position of the supporting leg 29, and the alarm module 32 is used to issue an alarm; after acquiring the image, the image acquisition module 30 sends the acquired image information to the judgment module 31, the image information is judged by the judgment module 31, and the judgment result is sent to the alarm module 32, and finally the judgment result is displayed by the alarm module 32.

[0072] A self-spray paint bottle 33 is detachably mounted on the support leg 29. The self-spray paint bottle 33 is used to spray marks on the ground. The marks can help staff members understand the source of the samples.

[0073] A protective cover 34 is provided on the movable sleeve of the support leg 29 , and the protective cover 34 is matched with the bottom end of the support leg 29 . The protective cover 34 is made of metal, and a magnetic plate 35 matched with the protective cover 34 is installed on the bracket 1 .

[0074] During the process of spraying self-spray paint, the protective cover 34 is located at the bottom of the support leg 29, so as to prevent the self-spray paint from being sprayed onto the surface of the support leg 29, thereby increasing the color difference between the bottom of the side wall of the support leg 29 and the mark sprayed on the ground, thereby improving the accuracy of the image captured by the image acquisition module 30.

[0075] During the process of collecting images, the protective cover 34 is pushed upward and fixed by the magnetic plate 35 , thereby ensuring that the image collection module 30 can work normally.

[0076] During the sampling process, the device will shake, so the device position is prone to deviation; first, the entire device is placed at the designated position, and then the staff takes the spray paint bottle 33 and sprays the sampling mark on the ground directly below the image acquisition module 30. The image acquisition module 30 is used to capture the position of the support leg 29 and the ground mark, and processes the collected information and then sends it to the judgment module 31;

[0077] The judging module 31 is used to judge the distance between the real-time position and the initial position of the supporting leg 29 and the ground mark, and send the result to the alarm module 32;

[0078] when ;

[0079] The alarm module 32 issues an alarm to inform the staff that the device position is offset;

[0080] when ;

[0081] The alarm module 32 does not work;

[0082] Wherein, D is the initial distance between the bottom wall edge of the support leg 29 and the marking edge, and d is the real-time distance between the bottom wall edge of the support leg 29 and the marking edge.

[0083] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
