Description

Technical Field

[0001] This invention relates to the field of road crack detection technology, specifically a crack detection device and method for road rock-forming agent materials. Background Technology

[0002] In road engineering, rock-forming agents can improve the water stability and weathering resistance of soil and rock materials. For example, in areas prone to rainwater erosion, roadbed materials treated with rock-forming agents are less susceptible to softening and erosion by water, maintaining better structural integrity and reducing road defects. After a period of use, roadbeds may develop cracks due to overload or weather conditions; however, cracks in roadbeds treated with rock-forming agents generally do not spread randomly, making them easier to detect and repair.

[0003] Current methods for detecting road cracks mainly rely on manual observation followed by filling the cracks with repair materials. This method is inefficient, labor-intensive, and unsuitable for detecting and repairing cracks on long stretches of road. Summary of the Invention

[0014] A method for detecting cracks in road rock-forming agent materials, as described above, includes the following steps: S1. Lowering the lifting frame and mounting plate using a lifting cylinder to bring the detection frame in the detection mechanism into contact with the road surface. The mounting plate continues to descend, causing the insertion tube within the detection frame to carry the detection bowl down, with the end of the insertion tube approaching the road surface. S2. Starting the air pump, the insertion tube sprays air outwards. When there are no cracks in the road surface, the airflow disperses, and the airflow entering the guide frame rushes towards the detection bowl, causing it to float. Displacement occurs between the detection bowl and the insertion tube. An electrical contact is provided at the initial contact point between the detection bowl and the insertion tube. When the insertion tube encounters a crack, the airflow enters the crack and cannot lift the detection bowl. The electrical contact connects to the circuit of the LED, thereby changing the resistance of the photoresistor strip and adjusting the position of the electric slider in the filling mechanism, which then fills the crack area with material. S3. Before detecting road surface cracks, the air outlet and spray nozzle in the cleaning mechanism are driven back and forth by the drive assembly to blow away dust and debris from the road surface, combined with dust suppression using the spray nozzle.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) Install the detection bowl through the insertion tube. A limit ring is set on the insertion tube at the bottom of the detection bowl to prevent the detection bowl from separating from the insertion tube. When the detection frame descends to the height of contact with the ground, continue to control the insertion tube to descend so that the insertion tube is close to the ground. At this time, combine with the horizontal air pipe to pump air into the insertion tube. When there is no crack in the ground, the airflow blown out of the insertion tube diffuses outward. Under the action of the guide frame, part of the airflow flows upward along the detection frame. At this time, the detection bowl is driven to float up along the insertion tube. At this time, the electrical contact on the insertion tube is separated from the electrical contact between the detection bowl, so that the lamp in the fastening frame is turned off. When there is a crack in the detection area, the airflow on the insertion tube directly enters the crack without driving the detection bowl to float up. At this time, the lamp remains lit, and then the position data of the crack is converted into the resistance value of the photoresistor strip. Combine with the resistance value to control the filling mechanism to adjust the position and perform the filling operation on the crack.

[0017] (2) The lifting frame and the bottom filling frame are lowered by the lifting cylinder II, so that the bottom of the filling frame contacts the ground. The electric slider moves in combination with the resistance value of the crack obtained in the detection mechanism, thereby driving the filling frame to the crack. The filling box pumps the filler into the filling frame, and the vibration block is used for vibration filling. The excess filler will move forward under the push of the filling frame, thus adapting to the filling and repair of cracks of different sizes.

[0018] (3) The horizontal moving plate is installed by means of a horizontal cylinder. When the crack cannot be detected, the horizontal cylinder is driven to move back and forth to eliminate the detection dead angle caused by the gap between adjacent insertion pipes. Attached Figure Description

[0033] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a crack detection device for road-use rock-forming agent materials includes a frame 1 and a filling box 10, a water tank 11, and an air pump 12 mounted on the frame 1. A connecting mechanism 2 is provided at the end of the frame 1, and a detection mechanism 3 and a filling mechanism 4 are mounted on the connecting mechanism 2. The detection mechanism 3 includes a lifting frame 23 and a mounting plate 24. The lifting frame 23 is movably mounted via a lifting cylinder 25. A horizontal air pipe 300 is mounted on the mounting plate 24, and insertion pipes 34 are evenly installed on the mounting plate 24, communicating with the horizontal air pipes 300. A detection frame is slidably mounted on the insertion pipes 34. The frame 31 has a protruding section 37 on the edge of the insertion tube 34. The detection frame 31 and the protruding section 37 cooperate with each other. The lower end of the insertion tube 34 is fitted with a detection bowl 38. The detection frame 31 has guide frames 39 on both sides inside. The insertion tube 34 has a connecting post 310. The lifting frame 23 has a fastening frame 311. The connecting post 310 extends to the inside of the fastening frame 311 and is connected to a lamp bead 3100. A photoresistor strip 312 is provided between the lifting frame 23 and the fastening frame 311. A spacer plate 3102 is provided between the lamp beads 3100 located in the fastening frame 311.

[0035] Specifically, the detection bowl 38 is installed through the insertion tube 34. A limit ring is provided on the insertion tube 34 at the bottom of the detection bowl 38 to prevent the detection bowl 38 from detaching from the insertion tube 34. When the detection frame 31 descends to the height of contact with the ground, the insertion tube 34 continues to descend, bringing it closer to the ground. At this time, air is pumped into the insertion tube 34 through the horizontal air pipe 300. When there are no cracks in the ground, the airflow blown out of the insertion tube 34 diffuses outward. Under the action of the guide frame 39, part of the airflow flows upward along the detection frame 31, causing the detection bowl 38 to float up along the insertion tube 34. At this time, the electrical contacts on the insertion tube 34 and the electrical contacts between the detection bowl 38 disengage, causing the LED 3100 located in the fastening frame 311 to turn off. When there are cracks in the detection area, the airflow on the insertion tube 34 directly enters the crack without causing the detection bowl 38 to float up. At this time, the LED 3100 remains constantly lit, thereby converting the crack position data into the resistance value of the photoresistor strip 312. Based on this resistance value, the filling mechanism 4 is adjusted to adjust its position and fill the crack.

[0036] Furthermore, such as Figure 8 , Figure 9As shown, the filling mechanism 4 includes a second lifting cylinder 41 and a second lifting frame 42. The second lifting cylinder 41 is connected to the connecting mechanism 2. The second lifting frame 42 is slidably installed between the connecting mechanism 2 and the lifting cylinder 41. The second lifting cylinder 41 is fixedly connected to the middle of the second lifting frame 42. The second lifting frame 42 is provided with a connecting slide rail 43 and an electric slider 44. A filling frame 45 is installed on the electric slider 44. The filling frame 45 is connected to the filling box 10. The filling frame 45 has a trapezoidal groove structure, and the trapezoidal groove structure points towards the detection mechanism 3. A discharge frame 46 is provided on both sides inside the filling frame 45. Discharge holes 47 are evenly provided on the discharge frame 46. A vibration block 48 is provided in the groove part of the filling frame 45.

[0037] Specifically, the lifting cylinder 41 controls the lowering of the lifting frame 42 and the bottom filling frame 45, so that the bottom of the filling frame 45 contacts the ground. The electric slider 44 moves in conjunction with the resistance value of the crack obtained in the detection mechanism 3, thereby moving the filling frame 45 to the crack. The filling box 10 pumps the sealant into the filling frame 45, and the vibration block 48 performs vibration filling. Excess sealant will move forward under the push of the filling frame 45, thus adapting to the filling and repair work of cracks of different sizes.

[0038] Furthermore, such as Figure 2 , Figure 3 As shown, the connecting mechanism 2 includes a horizontal moving plate 20, on which connecting sliders 201 are evenly arranged. The connecting sliders 201 are slidably installed with the end of the frame 1. A horizontal cylinder 200 is provided between the horizontal moving plate 20 and the frame 1. A vertical guide rail 1 21 and a vertical guide rail 22 are provided at the front end of the horizontal moving plate 20. The detection mechanism 3 is slidably installed with the vertical guide rail 1 21, and the filling mechanism 4 is slidably installed with the vertical guide rail 22.

[0039] Specifically, because there is a gap between adjacent connectors 34, when the gap is exactly between adjacent connectors 34, the crack cannot be detected. The horizontal moving plate 20 is moved using a horizontal cylinder 200. When the crack cannot be detected, the horizontal cylinder 200 is driven to move back and forth, eliminating the detection blind spot caused by the gap between adjacent connectors 34. The driving displacement of the horizontal cylinder 200 is equal to the gap between adjacent connectors 34.

[0040] Furthermore, such as Figure 6 , Figure 7As shown, a folded flexible tube 32 is provided between the horizontal air tube 300 and the insertion tube 34, a connecting spring 33 is provided between the insertion tube 34 and the mounting plate 24, an adjustment groove 3110 is provided at the connection part between the fastening frame 311 and the connecting column 310, and a folded light shield 3101 is provided at the adjustment groove 3110 of the fastening frame 311.

[0041] Furthermore, such as Figure 6 , Figure 7 As shown, a horizontal water pipe 301 is fixedly installed on the mounting plate 24, and a folded flexible hose 36 is connected to the protruding section 37 on the insertion pipe 34. The folded flexible hose 36 is connected to the horizontal water pipe 301, and a solenoid valve 35 is installed between the folded flexible hose 36 and the horizontal water pipe 301.

[0042] Specifically, in order to ensure that the sealant can better adhere to the crack, when the insertion tube 34 detects a crack, the solenoid valve 35 is opened simultaneously, allowing the end of the protruding section 37 to inject clean water into the crack, thereby cleaning the crack and preventing dust in the crack from affecting the subsequent filling effect of the sealant.

[0043] Furthermore, such as Figure 10 , Figure 11 , Figure 12 As shown, a cleaning mechanism 5 is provided at the front end of the mounting plate 24. The cleaning mechanism 5 includes a vertical plate 50 on the mounting plate 24. Wedge-shaped blocks 51 and 52 are evenly arranged on the vertical plate 50. An air outlet 53 is rotatably mounted on the wedge-shaped block 51, and a spray cylinder 55 is rotatably mounted on the wedge-shaped block 52. The air outlet 53 is connected to the horizontal air pipe 300 through a branch air pipe 56, and the spray cylinder 55 is connected to the horizontal water pipe 301 through a branch water pipe 57. Rotary connecting blocks 54 are respectively provided between the wedge-shaped block 51 and the air outlet 53, and between the wedge-shaped block 52 and the spray cylinder 55. A snap-fit ​​groove 540 is provided on the rotating connecting block 540. A snap-fit ​​block 580 is slidably installed in the snap-fit ​​groove 540. A linkage plate 58 is rotatably connected between the snap-fit ​​blocks 580, and a drive assembly 6 is connected to the linkage plate 58.

[0044] Specifically, to better monitor cracks continuously, wedge-shaped blocks 51 and 52 are used to rotate and install air outlet 53 and spray nozzle 55, respectively. First, the air outlet 53 cleans the road surface awaiting inspection, and then the spray nozzle 55 suppresses the dust, preventing excessive dust generation during operation. The movement of the linkage plate 58 causes the locking block 580 to slide within the locking groove 540, which in turn causes the rotating connecting block 54 to rotate around the connection point. This causes the air outlet 53 or spray nozzle 55 at the end to swing back and forth, improving cleaning and dust suppression effects.

[0045] Furthermore, such as Figure 13 As shown, the drive assembly 6 includes a connecting frame 60, which is fixedly installed between the connecting frame 60 and the vertical plate 50 via a fixing bracket 61. A drive bevel gear 63 is rotatably installed inside the connecting frame 60, and the drive bevel gear 63 is connected to a drive motor 62. Driven bevel gears 64 are rotatably installed on both sides of the connecting frame 60, and the driven bevel gears 64 mesh with the drive bevel gear 63 respectively. A connecting shaft 66 is rotatably installed at the end of the linkage plate 58, and a push-pull rod 65 is rotatably installed between the connecting shaft 66 and the driven bevel gear 64.

[0046] Specifically, the drive motor 62 drives the active bevel gear 63 and the driven bevel gear 64 to rotate, and the eccentrically mounted push-pull rod 65 and the connecting shaft 66 drive the linkage plate 58 to move back and forth, thereby controlling the air outlet 53 and the spray nozzle 55 to swing back and forth.

[0047] Furthermore, a support spring is provided between the two ends of the snap-fit ​​block 580 and the snap-fit ​​groove 540, and the branch water pipe 57 and the branch air pipe 56 are respectively fixedly installed on the linkage plate 58.

[0048] A method for detecting cracks in road rock-forming agent materials, as described above, includes the following steps: S1, controlling the lifting frame 23 and mounting plate 24 to descend via lifting cylinder 25, so that the detection frame 31 in the detection mechanism 3 contacts the road surface; at this time, continuing to control the mounting plate 24 to descend, so that the insertion tube 34 inside the detection frame 31 carries the detection bowl 38 down, controlling the end of the insertion tube 34 to approach the road surface; S2, starting the air pump 12, the insertion tube 34 sprays air outward; when there are no cracks in the road surface, the airflow disperses, and the airflow entering between the guide frames 39 will rush towards the detection bowl 38, causing the detection bowl 38 to float upward. At this time, the detection bowl 38... Displacement occurs between the insertion tube 34 and the detection bowl 38. The initial mating part between the insertion tube 34 and the detection bowl 38 is provided with an electrical contact. When the insertion tube 34 encounters a crack, the airflow will enter the crack and will not be able to lift the detection bowl 38. At this time, the electrical contact connects the circuit of the LED bead 3100, thereby changing the resistance value of the photoresistor strip 312, adjusting the position of the electric slider 44 in the filling mechanism 4, and carrying the filling mechanism 4 to fill the crack area with material; S3, before detecting the road surface crack, the drive component 6 drives the air outlet 53 and the spray tube 55 in the cleaning mechanism 5 to swing back and forth, thereby blowing away the dust and debris on the road surface, and combining with the spray tube 55 to reduce dust.

[0049] The working principle of this invention embodiment is as follows:

[0050] like Figures 1-13As shown, the detection bowl 38 is installed through the insertion tube 34. A limit ring is provided on the insertion tube 34 at the bottom of the detection bowl 38 to prevent the detection bowl 38 from detaching from the insertion tube 34. When the detection frame 31 descends to the height of contact with the ground, the insertion tube 34 continues to descend, bringing it closer to the ground. At this time, air is pumped into the insertion tube 34 through the horizontal air pipe 300. When there are no cracks in the ground, the airflow blown out of the insertion tube 34 diffuses outward. Under the action of the guide frame 39, part of the airflow flows upward along the detection frame 31, causing the detection bowl 38 to float up along the insertion tube 34. At this time, the electrical contacts on the insertion tube 34 and the detection bowl 38 disengage, causing the LED 3100 located in the fastening frame 311 to turn off. When there are cracks in the detection area, the airflow on the insertion tube 34 directly enters the crack without causing the detection bowl 38 to float up. At this time, the LED 3100 remains constantly lit, thereby converting the crack position data into the resistance value of the photoresistor strip 312. Based on this resistance value, the filling mechanism 4 is adjusted to adjust its position to fill the crack. The lifting cylinder 41 controls the lowering of the lifting frame 42 and the bottom filling frame 45, bringing the bottom of the filling frame 45 into contact with the ground. The electric slider 44 moves in conjunction with the resistance value of the crack location obtained from the detection mechanism 3, thereby moving the filling frame 45 to the crack location. The filling box 10 pumps sealant into the filling frame 45, and the vibrating block 48 performs vibration filling. Excess sealant is pushed forward by the filling frame 45, thus adapting to filling and repairing cracks of different sizes. Because there is a gap between adjacent insertion pipes 34, when the gap is exactly between adjacent insertion pipes 34, crack detection is impossible. The horizontal cylinder 200 moves the horizontal moving plate 20. When a crack cannot be detected, the horizontal cylinder 200 is driven to move back and forth, eliminating the detection blind spot caused by the gap between adjacent insertion pipes 34. The driving displacement of the horizontal cylinder 200 is equal to the gap between adjacent insertion pipes 34.
