Description

Technical Field

[0001] The present invention relates to the technical field of highway quality inspection, and particularly to a highway engineering pavement quality inspection device based on intelligent sensors and its inspection method. Background Art

[0002] A highway engineering pavement quality inspection device based on intelligent sensors usually consists of parts such as a test platform, a water tank, a graduated cylinder, and a power component.

[0003] The patent with the patent announcement number CN219694847U relates to a highway engineering pavement quality inspection device based on intelligent sensors, including a support base and a graduated cylinder. A connecting rod is provided at the rear end of the support base. The connecting rod is L-shaped, and a threaded hole is provided at the top of the connecting rod. A driving screw is provided in the middle of the threaded hole. The bottom end of the driving screw is rotatably connected to the graduated cylinder. A through hole is provided at the position of the support base aligned with the graduated cylinder. The axes of the driving screw, the graduated cylinder, and the through hole are on the same straight line. An adjusting rod is provided on the side of the support base away from the graduated cylinder. A water storage tank is installed on the adjusting rod. A drain pipe is provided at the bottom of the side of the water storage tank. A throttle valve is provided on the drain pipe. A water inlet pipe is provided at a position near the top of the graduated cylinder. The water inlet pipe and the drain pipe are connected by a hose. Mounting frames are inserted on both sides of the rear end of the support base. The graduated cylinder and the support base are connected by a driving screw, thus facilitating the use of the driving screw to drive the graduated cylinder to press down, and facilitating the graduated cylinder to be tightly pressed on the road surface.

[0004] In the above patent, by using the driving screw to drive the graduated cylinder to press down, it is convenient for the graduated cylinder to be tightly pressed on the road surface. However, it is difficult to ensure an appropriate contact force between the inspection cylinder and the road surface. If the contact force of the inspection cylinder is too weak, it will cause the inspection cylinder not to form a good contact with the road surface, and the insufficient contact will make the liquid loss during the inspection process unable to be effectively controlled, thereby leading to an inspection error of the water seepage volume.

[0012] According to the above technical solution, the anti-shake assembly includes a square groove, a T-shaped rod, an L-shaped rack, a transverse rod, a gear, and a semi-circular rod.

[0014] A detection method for a road engineering pavement quality detection device based on an intelligent sensor, using the above-mentioned road engineering pavement quality detection device based on an intelligent sensor, includes the following steps:

[0015] Step 1: The servo motor operates to drive the lead screw to rotate. The rotation of the lead screw drives the connecting plate to move downward. The downward movement of the connecting plate drives the detection cylinder to move downward.

[0016] Step 2: The downward movement of the detection cylinder drives the rubber ring to move downward to contact the road surface to be detected. The downward movement of the rubber ring contacts the road surface to be detected and presses the road surface to be detected.

[0017] Step 3: The rubber ring is deformed by the reaction force of the road surface to be detected when it is squeezed. The rubber ring is deformed and seals the inside of the detection cylinder.

[0018] Step 4: The water pump operates to introduce the liquid in the water tank into the detection cylinder through the connecting pipe and perform quality detection on the road surface to be detected.

[0019] Step 5: Observe the decrease in the water level inside the detection cylinder through the scale on the surface of the detection cylinder, and then obtain the result of the water permeability quality detection of the road surface to be detected.

[0020] The present invention provides a road engineering pavement quality detection device based on an intelligent sensor. It has the following beneficial effects:

[0021] (1) In this invention, by ensuring that the detection cylinder cannot move downward further, an appropriate contact force between the detection cylinder and the road surface is maintained. By ensuring that the detection cylinder cannot move downward further, the seepage state of the road surface during actual use can be better simulated, thereby obtaining more accurate evaluation data on the road surface water permeability. When the rubber ring contacts the detection hole, the rubber ring deforms and automatically sheds the foreign objects adhered to itself. By the deformation of the rubber ring causing the foreign objects to automatically fall off, the cleanliness when the detection cylinder contacts the road surface is ensured, and foreign object interference with the road surface water permeability test results is avoided.

[0022] (2) In this invention, the detection cylinder is assisted and fastened by the load-bearing frame in cooperation with the fixing frame. By means of the auxiliary fastening, the pressure between the detection cylinder and the road surface is kept consistent, thereby further avoiding detection errors caused by the movement of the detection cylinder position.

[0023] (3) In this invention, the moving ring moves to the left to contact the arc-shaped panel and cooperate with the arc-shaped panel to support the connection part of the connecting pipe. Through the cooperation and support of the moving ring and the arc-shaped panel, the connecting pipe can be prevented from bending or deforming due to external force, thereby ensuring the stability and uniformity of the water flow during the detection process, and thus improving the accuracy of the water permeability detection.

[0024] (4) In this invention, since the moving wheel cannot rotate, the detection table cannot move during the road surface quality detection process. By fixing the detection table, it can prevent the operator from accidentally colliding and causing the detection table to shake, thereby ensuring the reliability and accuracy of the test data.

[0025] (5) In this invention, the semi-circular rod is squeezed by the moving wheel to scrape off the foreign objects stuck on the surface of the moving wheel, thereby ensuring that the detection table is in a horizontal state during the road surface quality detection process. By ensuring that the detection table remains in a horizontal state, the liquid can evenly cover the test area and prevent liquid leakage, thus obtaining more accurate and reliable water permeability data.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 - 8, an embodiment of the present invention is: a road engineering pavement quality detection device based on intelligent sensors, including a detection table 1, and further including a detection component. A water tank 2 is fixedly installed on the top of the detection table 1, a connecting frame 3 is fixedly installed at the rear side of the detection table 1, a servo motor 4 is fixedly installed on the top of the connecting frame 3, a lead screw 5 is fixedly installed at the output end of the servo motor 4, a connecting plate 6 is slidably installed on the inner wall of the connecting frame 3, the connecting plate 6 is threadedly connected with the lead screw 5, a detection cylinder 7 is fixedly penetrated through the upper and lower walls of the connecting plate 6, and an intelligent sensor is arranged inside the detection cylinder 7. The intelligent sensor first performs visual detection on the road surface. A water pump 8 is fixedly installed on the left side of the water tank 2, a connecting pipe 9 is arranged between the water pump 8 and the water tank 2, a limiting hole 10 is opened at the rear side of the connecting frame 3, a limiting rod 11 is slidably penetrated through the inner and outer walls of the connecting frame 3, a limiting plate 12 is fixedly installed at the front side of the bottom of the limiting rod 11, a limiting groove 13 is opened at the front side of the limiting plate 12, a detection hole 131 is opened at the top of the detection table 1, a rubber ring 14 is fixedly installed at the bottom of the detection cylinder 7, and a scale is arranged on the circumferential surface of the detection cylinder 7. By ensuring that the detection cylinder 7 cannot continue to move downward, the seepage state of the road surface during actual use can be better simulated, so as to obtain more accurate road surface water permeability evaluation data.

[0037] A first spring is arranged between the limiting rod 11 and the connecting frame 3. The first spring can drive the limiting rod 11 to reset. The lead screw 5 penetrates through the top of the connecting frame 3. The rubber ring 14 contacts the detection hole 131. A linkage plate 15 is fixedly installed on the top of the connecting plate 6. The deformation of the rubber ring 14 makes foreign objects fall off automatically, ensuring the cleanliness when the detection cylinder 7 contacts the road surface, and avoiding the interference of foreign objects on the road surface water permeability test results.

[0038] The connecting plate 6 contacts the front side of the limiting plate 12. A moving wheel 174 is fixedly installed on the inner wall of the detection table 1. The detection table 1 can be conveniently moved through the moving wheel 174. The limiting plate 12 contacts the limiting hole 10.

[0039] A detection method of a road engineering pavement quality detection device based on intelligent sensors, using the above-mentioned road engineering pavement quality detection device based on intelligent sensors, includes the following steps:

[0040] Step 1: The servo motor 4 operates to drive the lead screw 5 to rotate. The rotation of the lead screw 5 drives the connecting plate 6 to move downward. The downward movement of the connecting plate 6 drives the detection cylinder 7 to move downward;

[0041] Step 2: The downward movement of the detection cylinder 7 drives the rubber ring 14 to move downward to contact the road surface to be detected. The downward movement of the rubber ring 14 contacts the road surface to be detected and squeezes the road surface to be detected;

[0042] Step 3: The rubber ring 14 is deformed by the reaction force of the road surface to be detected when being squeezed. The rubber ring 14 is deformed and seals the inside of the detection cylinder 7;

[0043] Step Four: The water pump 8 operates to introduce the liquid inside the water tank 2 into the detection cylinder 7 through the connecting pipe 9 and perform quality detection on the road surface to be detected;

[0044] Step Five: Observe the decline of the water level inside the detection cylinder 7 through the scale on the surface of the detection cylinder 7, and thus obtain the result of the quality detection of the water permeability of the road surface to be detected.

[0045] When this embodiment works: The servo motor 4 operates to drive the screw rod 5 to rotate. The rotation of the screw rod 5 drives the connecting plate 6 to move downward. The downward movement of the connecting plate 6 drives the detection cylinder 7 to move downward. The downward movement of the detection cylinder 7 drives the rubber ring 14 to move downward and contact the road surface to be detected. The rubber ring 14 moves downward and contacts the road surface to be detected and squeezes the road surface to be detected. The rubber ring 14 is subjected to the reaction force of the road surface to be detected and deforms. The rubber ring 14 deforms and seals the inside of the detection cylinder 7. At the same time, the connecting plate 6 moves downward and aligns with the limit groove 13. After the connecting plate 6 aligns with the limit groove 13, the limit rod 11 moves forward under the elastic force of the first spring. The forward movement of the limit rod 11 drives the limit plate 12 to move. The movement of the limit plate 12 causes the limit groove 13 to contact the connecting plate 6 and limit the connecting plate 6. The connecting plate 6 is limited by the limit plate 12 and cannot continue to move downward, so that the detection cylinder 7 cannot continue to move downward. The detection cylinder 7 cannot continue to move downward, thereby ensuring that the detection cylinder 7 maintains an appropriate contact force with the road surface. After the detection cylinder 7 is stably in contact with the road surface to be detected, the water pump 8 operates to introduce the liquid inside the water tank 2 into the detection cylinder 7 through the connecting pipe 9 and perform quality detection on the road surface to be detected. At the same time, observe the decline of the water level inside the detection cylinder 7 through the scale on the surface of the detection cylinder 7, and thus obtain the result of the quality detection of the water permeability of the road surface to be detected.

[0046] Please refer to Figures 1 - 8 On the basis of the above embodiment, in another embodiment of the present invention, a fastening component for improving the stability of the detection cylinder 7 is provided on the top of the detection table 1, and an anti-vibration component is provided on the inner wall of the detection table 1. The fastening component includes a fixing rod 161, a fixing frame 162, a load-bearing rod 166 and a load-bearing frame 167. The fixing rod 161 penetrates the left and right walls of the top of the detection table 1, and the fixing frame 162 is fixedly installed at both ends of the fixing rod 161. The load-bearing rod 166 penetrates the left and right walls of the top of the detection table 1, and the load-bearing frame 167 is fixedly installed at both ends of the load-bearing rod 166. A second spring is provided between the fixing rod 161 and the fixing frame 162, and a third spring is provided between the load-bearing rod 166 and the load-bearing frame 167. By means of auxiliary fastening, the pressure of the contact between the detection cylinder 7 and the road surface is kept consistent, thereby further avoiding detection errors caused by the position movement of the detection cylinder 7.

[0047] On the left side of the water pump 8, a circular plate 163 is fixedly installed. On the right side of the circular plate 163, an elastic telescopic rod 168 is fixedly installed. At the free end of the elastic telescopic rod 168, a moving ring 164 is fixedly installed. The elastic telescopic rod 168 can drive the moving ring 164 to reset. On the top of the water pump 8, an arc-shaped panel 165 is fixedly installed. When the moving ring 164 moves to the left, it contacts the arc-shaped panel 165 and cooperates with the arc-shaped panel 165 to support the connection part of the connecting pipe 9. Through the cooperative support of the moving ring 164 and the arc-shaped panel 165, the stability and uniformity of the water flow during the detection process can be ensured, thereby improving the accuracy of the water permeability detection.

[0048] The top of the fixed frame 162 is set as an inclined surface, and the top of the load-bearing frame 167 is set as an inclined surface. The linkage plate 15 moves downward to contact the inclined surface at the top of the fixed frame 162 and squeeze the fixed frame 162, and the arc-shaped panel 165 contacts the connecting pipe 9.

[0049] The anti-vibration assembly includes a square groove 171, a T-shaped rod 172, an L-shaped rack 173, a transverse rod 175, a gear 176 and a semi-circular rod 177. The square groove 171 is opened on the left side of the detection table 1. The T-shaped rod 172 is fixedly installed on the inner wall of the square groove 171. The L-shaped rack 173 is slidably installed on the circumferential surface of the T-shaped rod 172. The transverse rod 175 is fixedly installed on the surface of the moving wheel 174. The gear 176 is fixedly installed on the circumferential surface of the transverse rod 175. The semi-circular rod 177 is fixedly installed on the inner wall of the detection table 1. By fixing the detection table 1, the operator can be prevented from accidentally colliding and causing the detection table 1 to shake, thereby ensuring the reliability and accuracy of the test data.

[0050] A fourth spring is arranged between the T-shaped rod 172 and the L-shaped rack 173. The semi-circular rod 177 contacts the circumferential surface of the moving wheel 174. The L-shaped rack 173 contacts the load-bearing frame 167. The semi-circular rod 177 scrapes off the foreign objects stuck on the surface of the moving wheel 174 under the extrusion of the moving wheel 174. By ensuring that the detection table 1 remains horizontal, the liquid can evenly cover the test area and prevent liquid leakage.

[0051] When this embodiment works: The connecting plate 6 moves downward to drive the linkage plate 15 to move downward. The linkage plate 15 moves downward and contacts the inclined surface at the top of the fixed frame 162 and squeezes the fixed frame 162. The fixed frame 162 moves toward the detection cylinder 7 under the extrusion of the linkage plate 15. The fixed frame 162 moves toward the detection cylinder 7 and pulls the second spring. The second spring deforms and stores energy under the pull of the fixed frame 162. And the fixed frame 162 moves toward the detection cylinder 7 and contacts the detection cylinder 7 and tightens the detection cylinder 7. At the same time, the linkage plate 15 moves downward and contacts the inclined surface at the top of the load-bearing frame 167 and squeezes the load-bearing frame 167. The load-bearing frame 167 moves toward the detection cylinder 7 under the extrusion of the linkage plate 15. The load-bearing frame 167 moves toward the detection cylinder 7 and pulls the third spring. The third spring deforms and stores energy under the pull of the load-bearing frame 167. The load-bearing frame 167 cooperates with the fixed frame 162 to assist in tightening the detection cylinder 7. At the same time, the fixed frame 162 moves toward the detection cylinder 7 and contacts the moving ring 164 and squeezes the moving ring 164. The moving ring 164 moves to the left under the extrusion of the fixed frame 162. The moving ring 164 moves to the left to drive the free end of the elastic telescopic rod 168 to retract. At the same time, the moving ring 164 moves to the left and contacts the arc-shaped panel 165 and cooperates with the arc-shaped panel 165 to support the connection part of the connecting pipe 9.

[0052] The load-bearing frame 167 moves toward the detection cylinder 7 under the extrusion of the linkage plate 15. The load-bearing frame 167 moves toward the detection cylinder 7 and disengages from the contact with the L-shaped rack 173. After the L-shaped rack 173 disengages from the contact with the load-bearing frame 167, the L-shaped rack 173 moves toward the transverse rod 175 under the elastic force of the fourth spring. The L-shaped rack 173 moves toward the transverse rod 175 and contacts the gear 176 and limits the gear 176. The gear 176 cannot rotate freely under the limitation of the L-shaped rack 173. The gear 176 cannot rotate freely, so that the transverse rod 175 cannot rotate. The transverse rod 175 cannot rotate, so that the moving wheel 174 cannot rotate. The moving wheel 174 cannot rotate, so that the detection table 1 cannot move during the road surface quality detection. And the movement of the detection table 1 will drive the moving wheel 174 to rotate. The moving wheel 174 rotates and contacts the semi-circular rod 177 and squeezes the semi-circular rod 177. The semi-circular rod 177 squeezes the foreign matter stuck on the surface of the moving wheel 174 under the extrusion of the moving wheel 174, thereby ensuring that the detection table 1 is in a horizontal state during the road surface quality detection.

9. A detection method for a pavement quality detection device of highway engineering based on intelligent sensors, using a pavement quality detection device of highway engineering based on intelligent sensors as described in claim 8, characterized in that, It includes the following steps: Step 1: The servo motor (4) operates to drive the screw rod (5) to rotate. The rotation of the screw rod (5) drives the connecting plate (6) to move downward. The downward movement of the connecting plate (6) drives the detection cylinder (7) to move downward. Step 2: The downward movement of the detection cylinder (7) drives the rubber ring (14) to move downward to contact the road surface to be detected. The downward movement of the rubber ring (14) contacts the road surface to be detected and squeezes the road surface to be detected. Step 3: The rubber ring (14) is deformed by the reaction force of the road surface to be detected when being squeezed. The rubber ring (14) is deformed and seals the inside of the detection cylinder (7). Step 4: The water pump (8) operates to introduce the liquid in the water tank (2) into the detection cylinder (7) through the connecting pipe (9) and perform quality detection on the road surface to be detected. Step 5: Observe the drop of the water level inside the detection cylinder (7) through the scale on the surface of the detection cylinder (7), and then obtain the result of the quality detection of the water permeability of the road surface to be detected.
