Description

Technical Field

[0001] This invention relates to the field of asphalt adhesion testing technology, specifically to an intelligent sensing and automatic control device and method for asphalt adhesion testing with added anti-stripping agent. Background Technology

[0002] As the most important binder in road engineering, asphalt's adhesion to aggregates directly affects the water stability of asphalt mixtures and the service life of pavements. In the presence of moisture, the asphalt film is easily peeled off from the aggregate surface, leading to early damage such as loosening and potholes on the pavement.

[0003] To improve the adhesion between asphalt and aggregates, it is usually necessary to add anti-stripping agents to the asphalt, thereby enhancing its resistance to water damage by changing the physicochemical properties of the asphalt-aggregate interface.

[0004] The content of anti-stripping agent in asphalt also needs to be tested to ensure that the asphalt has the best adhesion. This can be done by testing asphalt with different contents of anti-stripping agent using the water immersion method. By observing the peeling area of ​​the asphalt film after the aggregate coated with asphalt is boiled in boiling water for a period of time, the adhesion performance of the asphalt under this condition can be obtained.

[0005] However, the water immersion test is usually a static immersion and boiling test, which can only simulate the effects of heat and water. It cannot simulate the complex mechanical environment generated by the dynamic water scouring, shearing and wheel splashing impact generated when vehicles are driving on the real road surface. As a result, the test results are not strongly correlated with the actual service conditions of the road surface and cannot effectively predict the long-term performance of the material. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent sensing and automatic control device and method for testing the addition of anti-stripping agents to asphalt adhesion, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A smart sensor-controlled automatic control device for testing the adhesion of asphalt to the addition of anti-stripping agents includes: The treatment tank and the lifting platform are equipped with an impregnation tank, a test tank, and a support platform. The bottom of the treatment tank is connected to a conduit that communicates with the impregnation tank. A sensor is installed inside the treatment tank, which can intelligently and automatically add a certain amount of anti-stripping agent to the asphalt in the treatment tank according to a set value. Also includes: A lifting assembly is mounted on the support platform. A lifting plate is connected to the lifting assembly. A translation assembly is mounted on the lifting plate. A movable plate is connected to the translation assembly. A clamping mechanism is provided on the movable plate. The clamping mechanism is connected to clamping columns arranged symmetrically for clamping the aggregate. The clamping mechanism is also provided with a follow-up positioning mechanism. A spiral impact mechanism is mounted on the lifting plate and connected to the test tank. The follow-up positioning mechanism can move when the spiral impact mechanism guides the water flow to impact the aggregate, and controls the clamping column to perform rotational positioning work through the clamping mechanism.

[0008] As a further embodiment of the present invention: the clamping mechanism includes a fixed rod fixed on the movable plate, a receiving plate is provided at the end of the fixed rod, and symmetrically arranged sliding grooves are formed on the receiving plate, and a sliding block is slidably installed in the sliding groove; It also includes a driven component and a pushing component disposed on the sliding block for adjusting the distance between the two clamping posts.

[0009] As a further embodiment of the present invention: the driven component includes an extension plate fixed on the sliding block, a rotating rod rotatably mounted on the extension plate, a blade and a support disk provided on the rotating rod, and the support disk being fixedly connected to the clamping column.

[0010] As a further embodiment of the present invention: the pushing assembly includes a connecting plate that slides along the axial direction of the fixed rod, a second cylinder that is fixedly connected to the connecting plate is provided on the movable plate, and a connecting rod that is hinged to the sliding block is hinged to the connecting plate.

[0011] As a further embodiment of the present invention, the two support discs are connected to each other by a telescopic rod.

[0012] As a further embodiment of the present invention: the follow-up positioning mechanism includes a plurality of spiral grooves formed on the rotating rod and distributed equidistantly around the circumference, the rotating rod having a movable sleeve that slides axially, and the inner wall of the movable sleeve being provided with a limiting block that slides and engages with the spiral grooves.

[0013] As a further embodiment of the present invention: a sealing tube is provided on the extension plate, a groove is formed on the inner wall of the sealing tube, a limiting ring is provided on the movable sleeve to slide and fit into the groove, a spring is sleeved on the rotating rod, and the two ends of the spring abut against the limiting ring and the extension plate respectively.

[0014] As a further embodiment of the present invention: the spiral impact mechanism includes a fixed tube fixed to the lifting plate and connected to the test tank, and a spiral guide plate is provided inside the fixed tube.

[0015] As a further embodiment of the present invention: the spiral impact mechanism further includes a support sleeve fixed inside the fixed tube, a support rod slidably installed inside the support sleeve, a piston disc slidably and sealingly connected to the fixed tube at the end of the support rod, and a first cylinder fixedly connected to the piston disc inside the fixed tube.

[0016] A method for testing the adhesion of asphalt to an intelligently sensed and automatically controlled anti-stripping agent, comprising the following steps: Step 1: The anti-stripping agent and asphalt are mixed in a treatment tank, and the treated asphalt is then transported to the impregnation tank through a conduit. Step 2: Place the aggregate into the impregnation tank, adjust the position of the movable plate by the translation component, and then adjust the height of the lifting plate by the lifting component so that the clamping column enters the impregnation tank; Step 3: The clamping mechanism controls the clamping column to clamp the aggregate, and under the action of the lifting component and the translation component, the clamping column extends into the test tank for water immersion treatment; Step 4: The spiral impact mechanism performs suction and spraying treatment on the water in the test tank, so that the water flows in a vortex shape and impacts the aggregate. Under the action of the clamping mechanism and the follow-up positioning mechanism, the aggregate is controlled to flip by the clamping column.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention achieves precise control of the anti-stripping agent dosage and thorough and uniform mixing with asphalt by integrating sensors and a stirring structure inside the processing tank, and ensures the strict execution of the isothermal development process, thus ensuring that subsequent tests provide modified asphalt samples with consistent and reliable performance.

[0018] By using a spiral impact mechanism to draw in and discharge water from the test tank, the water can flow in a spiral pattern and impact the aggregate surface, thereby providing the aggregate surface with a continuous spiral shear force. This simulates the scouring effect of dynamic water pressure in road voids, as well as the impact force when water is periodically discharged, simulating the instantaneous impact of water splashing from vehicle wheels. In this way, the test results can more realistically reflect the water damage resistance of asphalt mixtures.

[0019] Under the impact of water flow, the aggregate is actively flipped through the cooperation of the clamping mechanism and the follow-up positioning mechanism. That is, when the aggregate is subjected to a specific impact force, the water flow impact force can overcome the spring locking force, causing the aggregate to automatically flip half a turn, thereby realizing continuous and all-round testing of multiple surfaces of the aggregate.

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.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0034] Please see Figures 1-11 In this embodiment of the invention, an intelligent sensing and automatic control device for testing the adhesion of asphalt by adding anti-stripping agents includes: The treatment tank 1 and the lifting plate 3 are provided. The lifting plate 3 is equipped with an immersion tank 4, a test tank 6, and a support platform 12. The bottom of the treatment tank 1 is connected to a conduit 2 that is connected to the immersion tank 4. Also includes: A lifting assembly is mounted on the support platform 12. A lifting plate 13 is connected to the lifting assembly. A translation assembly is mounted on the lifting plate 13. A movable plate 14 is connected to the translation assembly. A clamping mechanism is provided on the movable plate 14. The clamping mechanism is connected to clamping columns 25 arranged symmetrically for clamping the aggregate. The clamping mechanism is also provided with a follow-up positioning mechanism. The spiral impact mechanism is mounted on the lifting plate 3 and connected to the test tank 6. The follow-up positioning mechanism can move when the spiral impact mechanism guides the water flow to impact the aggregate, and controls the clamping column 25 to perform rotational positioning work through the clamping mechanism.

[0035] The lifting assembly includes a guide rail fixed on the support platform 12, a first motor, and a first lead screw rotatably mounted on the support platform 12 and connected to the output shaft of the first motor. A first threaded sleeve is threadedly connected to the first lead screw. The lifting plate 13 is fixedly connected to the first threaded sleeve and slidably connected to the guide rail. The translation assembly includes a guide column fixed on the lifting plate 13. A guide sleeve is slidably mounted on the guide column. A side plate is provided at the end of the guide column. A second motor is provided on the side plate. A second lead screw rotatably mounted on the lifting plate 13 and connected to the output shaft of the second motor is threadedly connected to the second lead screw. A second threaded sleeve is threadedly connected to the second lead screw. The movable plate 14 is fixedly connected to the second threaded sleeve and the guide sleeve.

[0036] Specifically, a sensor is installed inside the treatment tank 1. This sensor can intelligently and automatically add a fixed amount of anti-stripping agent to the asphalt in the treatment tank 1 according to a set value. The treatment tank 1 also integrates a stirring structure, which can mix the asphalt and anti-stripping agent. After mixing, it undergoes constant temperature development for a certain period of time. After development is complete, the asphalt can be transported to the impregnation tank 4 through the conduit 2. At this time, aggregates can be added to the impregnation tank 4, and the asphalt adheres to the surface of the aggregates. Simultaneously, the lifting component and the translation component drive the lifting plate 13 and the movable plate 14 to move, so that the clamps... The holding column 25 extends into the immersion tank 4, and the clamping mechanism controls the holding column 25 to clamp the aggregate. After clamping, the lifting component and the translation component control the lifting plate 13 and the movable plate 14 to move again, so that the holding column 25 leaves the immersion tank 4 and enters the test tank 6, immersing the aggregate in water. At this time, the spiral impact mechanism works and guides the water in the test tank 6 to flow in a spiral shape and impact the surface of the aggregate. The water flow impact force also drives the clamping mechanism to move, and under the action of the follow-up positioning mechanism, the holding column 25 controls the aggregate to flip, thereby ensuring that the aggregate can be fully tested.

[0037] Please see Figures 1-3 , Figures 6-8 , Figure 11The clamping mechanism includes a fixed rod 15 fixed to the movable plate 14, a receiving plate 16 at the end of the fixed rod 15, symmetrically arranged sliding grooves 1601 formed on the receiving plate 16, and a sliding block 17 slidably installed in the sliding groove 1601; it also includes a driven component and a pushing component disposed on the sliding block 17 for adjusting the distance between the two clamping columns 25. The driven component includes an extension plate 1701 fixed to the sliding block 17, a rotating rod 22 rotatably mounted on the extension plate 1701, a blade 23 and a support plate 24 disposed on the rotating rod 22, the support plate 24 being fixedly connected to the clamping column 25. The pushing component includes a connecting plate 19 sliding along the axial direction of the fixed rod 15, a second cylinder 18 fixedly connected to the connecting plate 19 disposed on the movable plate 14, a connecting rod 20 hinged to the sliding block 17 on the connecting plate 19, and the two support plates 24 being interconnected by a telescopic rod 26.

[0038] Please see Figure 4 In detail, the immersion tank 4 is equipped with a lifting platform 5, which can be driven by a hydraulic cylinder to control the immersion or detachment of the asphalt. The test tank 6 is equipped with a resistance heater, which can heat the water in the test tank 6 to realize the subsequent water immersion test. Please see Figure 6 , Figure 7 In the initial state, under the action of the second cylinder 18, the connecting plate 19 is located at the end of its stroke in the direction close to the receiving plate 16. The connecting plate 19 will control the two sliding blocks 17 to be located at the end of their stroke in the direction away from each other through the connecting rod 20. That is, the sliding block 17 is located on the side of the slide groove 1601 away from the fixed rod 15. In this regard, the distance between the two support plates 24 and the two clamping columns 25 is the largest. When it is necessary to clamp the aggregate and guide it into the test tank 6, the second motor works and drives the second lead screw to rotate, thereby driving the second threaded sleeve to move. The second threaded sleeve will drive the guide sleeve to slide along the axial direction of the guide column through the movable plate 14. Since the guide sleeve and the guide column have a guiding function, it can ensure that the second threaded sleeve slides along the axial direction of the second lead screw and will not follow the rotation of the second lead screw. The movable plate 14 will also drive the fixed rod 15 to move, thereby driving the clamping column 25 to move to the position directly above the impregnation tank 4 through the clamping mechanism. When the clamping column 25 reaches the required horizontal position, the first motor works and drives the first lead screw to rotate, thereby driving the lifting plate 13 to slide along the guide rail through the first threaded sleeve. The lifting plate 13 will control the movable plate 14 to move towards the impregnation tank 4 through the translation component, thereby driving the clamping column 25 into the impregnation tank 4. At the same time, the lifting platform 5 is raised and the aggregate is controlled to detach from the asphalt to ensure that the clamping mechanism does not adhere to the asphalt. Subsequently, when the clamping column 25 moves to the same horizontal plane as the aggregate, the second cylinder 18 works and controls the connecting plate 19 to move away from the receiving plate 16. This causes the two sliding blocks 17 to slide along the slide groove 1601 and move towards each other via the connecting rod 20. The sliding blocks 17 will drive the rotating rod 22 to move via the extension plate 1701, thereby driving the support plate 24 and the clamping column 25 to move. When the clamping column 25 comes into contact with the aggregate, it indicates that the clamping of the aggregate is complete. When the two support plates 24 are close to each other, the telescopic rod 26 is in a continuously retracted state. At this time, the lifting component and the translation component control the movement of the movable plate 14 and the lifting plate 13 again, so that the clamping column 25 drives the aggregate to leave the impregnation tank 4 and enter the test tank 6, and immerses the aggregate in the water in the test tank 6. Under the action of heated water flow, the adhesion test of the asphalt on the surface of the aggregate is carried out. After this test is completed, different proportions of anti-stripping agent can be added to the treatment tank 1 and mixed with asphalt. After the aggregate is adhered again, an adhesion test is conducted to obtain the change in the adhesion of asphalt when different proportions of anti-stripping agent are added, so as to obtain the optimal anti-stripping agent addition ratio.

[0039] Please see Figures 1-3 , Figures 6-10 The follow-up positioning mechanism includes a plurality of spiral grooves 2201 formed on the rotating rod 22 and distributed equidistantly around the circumference. A movable sleeve 27 slides axially on the rotating rod 22. A limiting block 2701 is provided on the inner wall of the movable sleeve 27 and slides into the spiral grooves 2201. A sealing tube 21 is provided on the extension plate 1701. A groove 2101 is formed on the inner wall of the sealing tube 21. A limiting ring 28 is provided on the movable sleeve 27 and slides into the groove 2101. A spring 29 is sleeved on the rotating rod 22. The two ends of the spring 29 abut against the limiting ring 28 and the extension plate 1701, respectively.

[0040] Please see Figure 4 , Figure 5 The spiral impact mechanism includes a fixed tube 7 fixed on the lifting plate 3 and connected to the test tank 6. A spiral guide plate 701 is provided inside the fixed tube 7. The spiral impact mechanism also includes a support sleeve 8 fixed inside the fixed tube 7. A support rod 9 is slidably installed inside the support sleeve 8. A piston disc 10 is provided at the end of the support rod 9 and is slidably and sealingly connected to the fixed tube 7. A first cylinder 11 is provided inside the fixed tube 7 and is fixedly connected to the piston disc 10.

[0041] Please see Figure 10Furthermore, the spiral groove 2201 is provided in two sets, each set consisting of two spiral grooves 2201 symmetrically combined. The two adjacent spiral grooves 2201 are combined to form a V-shaped groove structure. In the initial state, the distance between the limiting ring 28 and the extension plate 1701 is the largest, so that the limiting block 2701 is located at the center of the V-shaped groove structure. The extension of the spring 29 in its natural state is greater than the maximum distance between the limiting ring 28 and the extension plate 1701. Therefore, the spring 29 is in a pre-compressed state and always provides the limiting ring 28 with a thrust in the direction away from the extension plate 1701. In this way, under the action of the limiting block 2701 and the spiral groove 2201, the angle of the rotating rod 22 is locked. Please see Figure 4 The piston disc 10 divides the fixed tube 7 into two chambers, namely the connecting chamber that is connected to the test tank 6 and the yielding chamber. Under the action of the first cylinder 11, the piston disc 10 is located at the end of its stroke in the direction close to the test tank 6. At this time, the size of the connecting chamber is the smallest and the size of the yielding chamber is the largest. When an adhesion test is required on the asphalt on the aggregate, the piston disc 10 is controlled to move away from the test tank 6 under the action of the first cylinder 11, and the support rod 9 is driven to move into the support sleeve 8. At this time, the size of the connecting chamber increases, and the size of the displacement chamber decreases. The water in the test tank 6 will enter the fixed pipe 7, and under the guidance of the spiral guide plate 701, the water flow will be spiral. After the piston disc 10 moves a certain distance, the first cylinder 11 controls the piston disc 10 to move closer to the test tank 6, and drives the support rod 9 to move away from the support sleeve 8, so that the size of the connecting chamber decreases. Under the action of the spiral guide plate 701, the water flow is spiraled again and transported into the test tank 6. The water flow will act on the aggregate surface, and the spiral water flow will form a continuous circumferential shear force on the aggregate surface, simulating the dynamic water scouring effect formed by the tires of vehicles on a real road. At the same time, when the water flow is discharged at high speed from the fixed pipe 7, the pulse impact force generated will further act on the asphalt film surface, simulating the instantaneous peeling effect of water splashed by the wheels. In this way, through the combined action of the two forces, the adhesion effect of asphalt during use can be tested more realistically.

[0042] Please see Figure 9During this process, the impact force of the water flow will drive the blade 23 to rotate the rotating rod 22. When the impact force exceeds the preload of the spring 29, the rotating rod 22 will rotate and drive the spiral groove 2201 to move. Under the action of the limiting block 2701, the movable sleeve 27 first moves towards the direction closer to the extension plate 1701 and compresses the spring 29 through the limiting ring 28. At this time, the spring 29 provides resistance to the movement of the limiting ring 28. When the limiting block 2701 moves to the position where the spiral groove 2201 connects with the adjacent spiral groove 2201, that is, when the limiting block 2701 is at the end of its stroke on the side closer to the extension plate 1701, the spring 29 is released elastically and pushes... The moving limiting ring 28 and the movable sleeve 27 move toward the initial position, causing the limiting block 2701 to enter the next spiral groove 2201. Since the V-shaped groove structure formed by the adjacent spiral grooves 2201 has a guiding effect, the limiting block 2701 pushes the rotating rod 22 to rotate at a specific angle during the sliding process in the spiral groove 2201. Thus, the clamping column 25 is controlled by the support plate 24 to drive the aggregate to rotate precisely 180°. In this way, the aggregate can be actively controlled to automatically change its surface when the water flow is subjected to dual tests of shear force and impact force. This allows for the simulation of a multi-dimensional mechanical environment, ensuring that the test results more accurately reflect the adhesion performance of the asphalt mixture in actual applications.

[0043] The first cylinder 11 can also precisely adjust the intensity and frequency of water flow impact, thereby achieving the effect of accurately testing the adhesion of asphalt under different working conditions.

[0044] Finally, when the number of cyclic impacts reaches the set value, the aggregate can be controlled to detach from the test tank 6, and the amount of asphalt peeling off the aggregate surface can be detected by the camera module, thereby determining the degree of improvement of the anti-stripping agent on the asphalt adhesion performance at this ratio.

[0045] A method for testing the adhesion of asphalt to an intelligently sensed and automatically controlled anti-stripping agent, comprising the following steps: Step 1: The anti-stripping agent and asphalt are mixed in the treatment tank 1, and the treated asphalt is then transported to the impregnation tank 4 through the conduit 2; Step 2: Place the aggregate into the impregnation tank 4, adjust the position of the movable plate 14 by the translation component, and then adjust the height of the lifting plate 13 by the lifting component so that the clamping column 25 enters the impregnation tank 4. Step 3: The clamping column 25 is controlled by the clamping mechanism to clamp the aggregate, and under the action of the lifting component and the translation component, the clamping column 25 is inserted into the test tank 6 for water immersion treatment; Step 4: The spiral impact mechanism performs suction and spraying treatment on the water in the test tank 6, so that the water flows in a vortex shape and impacts the aggregate. Under the action of the clamping mechanism and the follow-up positioning mechanism, the aggregate is controlled to flip by the clamping column.

A method for testing the adhesion of asphalt with intelligent sensing and automatic control of anti-stripping agent addition, comprising the asphalt adhesion testing device for intelligent sensing and automatic control of anti-stripping agent addition as described in any one of claims 1-9, characterized in that, Includes the following steps: Step 1: The anti-stripping agent and asphalt are mixed in a treatment tank, and the treated asphalt is then transported to the impregnation tank through a conduit. Step 2: Place the aggregate into the impregnation tank, adjust the position of the movable plate by the translation component, and then adjust the height of the lifting plate by the lifting component so that the clamping column enters the impregnation tank; Step 3: The clamping mechanism controls the clamping column to clamp the aggregate, and under the action of the lifting component and the translation component, the clamping column extends into the test tank for water immersion treatment; Step 4: The spiral impact mechanism performs suction and spraying treatment on the water in the test tank, so that the water flows in a vortex shape and impacts the aggregate. Under the action of the clamping mechanism and the follow-up positioning mechanism, the aggregate is controlled to flip by the clamping column.
