Description

Technical Field

[0001] This utility model relates to the technical field of asphalt testing, specifically to a modified asphalt testing device containing an active compatibilizer. Background Technology

[0002] Solubilizers are a type of surfactant that increases the solubility of substances that are originally sparingly soluble or insoluble in a solvent. The solubilizing effect of solubilizers is due to their presence of both hydrophilic and lipophilic groups. When they enter a medium, the lipophilic groups extend inwards, and the hydrophilic groups extend outwards (non-ionic hydrophilic groups extend from the surface of oil droplets into the aqueous phase in a wavy pattern), forming micelles. Asphalt is a complex, dark brown mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It has high viscosity and typically exists in a liquid or semi-solid state.

[0003] Utility model patent CN219346624U discloses a modified asphalt testing device containing an active compatibilizer, belonging to the field of asphalt testing technology. It addresses the problem in existing technologies where comparing the density of multiple asphalt samples requires separate density measurements and calculations for each sample, resulting in numerous steps. Furthermore, in repeated measurements, if water is poured into the container, the water may not be completely dry due to short intervals, leading to errors during subsequent measurements. The device includes a base plate, with its sides equipped with… A lifting frame assembly is provided, with an asphalt fixing component installed at its bottom. A transparent glass cylinder is located at the bottom of the asphalt fixing component, and a glass cylinder base is engaged with the bottom of the transparent glass cylinder. A liquid level detection component is located on the back of the transparent glass cylinder. The lifting frame assembly includes a vertical support column, a square lifting cylinder, a limiting bolt, a connecting beam, a supporting beam, a side lifting column, a limiting slider, a limiting groove, and a side lifting cylinder.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 The present invention will describe the above technical solution in detail through the following embodiments:

[0027] A modified asphalt testing device containing an active compatibilizer includes: a base plate 1; a gantry frame 2 is fixedly connected to the top of the base plate 1, and two guide rails 3 are provided at the bottom of the gantry frame 2. A movable block 4 is slidably connected to the outer surface of one end of each guide rail 3. The two movable blocks 4 are fixedly connected by an operating table 5. An asphalt body 6 is provided at the top center of the operating table 5; an extrusion mechanism 7 is provided inside the gantry frame 2 to improve the safety performance of the device; clamping mechanisms 8 are provided on both sides of the asphalt body 6 to prevent displacement of the asphalt body 6. The user fixes the asphalt body 6 on the operating table 5 through the clamping mechanisms 8, and then performs hardness testing on the asphalt body 6 through the extrusion mechanism 7.

[0028] like Figure 3 As shown, the extrusion mechanism 7 includes: a lifting plate 9 is installed inside the gantry frame 2; two L-shaped rods 10 are slidably connected to one side of the lifting plate 9; a first limiting plate 11 is fixedly connected to the top of the L-shaped rods 10; a first spring 12 is sleeved on the outer surface of the L-shaped rods 10 near the lifting plate 9; a second limiting plate 13 is provided at the bottom of each first spring 12; the second limiting plates 13 are fixedly connected to the L-shaped rods 10 respectively; and hydraulic cylinders 14 are fixedly connected to both sides of the bottom of the gantry frame 2; the telescopic ends of the hydraulic cylinders 14 are respectively connected to... The gantry 2 extends to the lifting plate 9, which is fixedly connected to the telescopic end of the hydraulic cylinder 14. A right-angle rod 15 is provided at the bottom of each L-shaped rod 10. A first rotating shaft 16 is rotatably connected to the middle of each right-angle rod 15. Support blocks 17 are fixedly connected to both ends of the first rotating shaft 16, and each support block 17 is fixedly connected to the base plate 1. A stroke groove 18 is provided at the end of each right-angle rod 15 away from the L-shaped rod 10. A matching cylindrical block 19 is provided inside each stroke groove 18, and a fixed end of each cylindrical block 19 is fixedly connected to a fixed... Block 20 and fixed block 20 are both fixedly connected to the operating table 5. When the hydraulic cylinder 14 is activated, the telescopic end of the hydraulic cylinder 14 extends downward, pushing the lifting plate 9 downward. As the lifting plate 9 moves downward, it pushes the second limiting plate 13 through the first spring 12. The second limiting plate 13 drives the L-shaped rod 10 downward. As the L-shaped rod 10 moves downward, it squeezes the right-angle rod 15, causing the right-angle rod 15 to rotate around the first rotating shaft 16. While rotating, the right-angle rod 15 pulls the cylindrical block 19 through the stroke groove 18. The cylindrical block 19 drives the operating table 5 through the fixed block 20. The operating table 5 slides horizontally on the guide rail 3 through the moving block 4. While the operating table 5 is sliding, it drives the asphalt body 6, thereby transporting the asphalt body 6 into the interior of the device. When the right-angle rod 15 rotates to the bottom plate 1 near the end of the L-shaped rod 10, the telescopic end of the hydraulic cylinder 14 continues to push the lifting plate 9 downward. At this time, the L-shaped rod 10 is stationary, and the lifting plate 9 continues to slide downward on the surface of the L-shaped rod 10, thereby detecting the hardness of the asphalt body 6.

[0029] like Figure 4As shown, a second rotating shaft 21 is fixedly connected to one end of the right-angle rod 15 near the L-shaped rod 10. Rollers 22 are rotatably connected to the outer surface of the middle part of the second rotating shaft 21. The rollers 22 cooperate with the L-shaped rod 10 to reduce the friction at the contact point between the right-angle rod 15 and the L-shaped rod 10, thereby preventing wear at the contact point between the right-angle rod 15 and the L-shaped rod 10.

[0030] like Figure 5 As shown, each of the moving blocks 4 is equipped with a reset block 23, and each of the reset blocks 23 is equipped with a second spring 24 on one side. The second spring 24 is respectively located inside the guide rail 3. When the extension end of the hydraulic cylinder 14 retracts and drives the lifting plate 9 to rise, the lifting plate 9 pulls the L-shaped rod 10 to rise and reset through the first limit plate 11. At this time, the pressure at one end of the right-angle rod 15 disappears, and the second spring 24 elastically recovers and pushes the moving block 4 to reset through the reset block 23. While the moving block 4 slides and resets on the surface of the guide rail 3, it drives the operating table 5. The operating table 5 pulls the fixed block 20, and the fixed block 20 drives the cylindrical block 19. The cylindrical block 19 pulls one end of the right-angle rod 15 through the stroke groove 18, so that the right-angle rod 15 rotates in the opposite direction with the first rotating shaft 16 as the center, thereby achieving the purpose of reset.

[0031] like Figure 4 As shown, the clamping mechanism 8 includes: clamping blocks 25 are provided on both sides of the asphalt body 6, and threaded blocks 26 are fixedly connected to the bottom of each clamping block 25. The bottom of each threaded block 26 penetrates through the operating table 5 and extends into the interior of the operating table 5. A bidirectional screw 27 is provided inside the operating table 5. One end of the bidirectional screw 27 is rotatably connected to the operating table 5, and the other end of the bidirectional screw 27 penetrates through the operating table 5 and extends to a knob 28. The knob 28 is fixedly connected to the bidirectional screw 27. The two threaded blocks 26 are threadedly connected to the outer surfaces of the two ends of the bidirectional screw 27, respectively. The top of each clamping block 25 is provided with a number of... Two triangular plates 29 are fixedly connected to clamping blocks 25 respectively. Two structural plates 30 are provided on the opposite side of the two threaded blocks 26. The structural plates 30 are fixedly connected to the threaded blocks 26 and clamping blocks 25. The user places the asphalt body 6 on the operating table 5 and then rotates the knob 28. The knob 28 drives the bidirectional screw 27 to rotate. While the bidirectional screw 27 rotates, it drives the threaded blocks 26 on both sides to move closer to each other. While the threaded blocks 26 move closer to each other, it drives the clamping blocks 25, so that the two clamping blocks 25 cooperate to clamp and fix the asphalt body 6.

[0032] like Figure 1 and Figure 2As shown, a connecting block 31 is fixedly connected to the bottom of the lifting plate 9 near the operating platform 5. A pressure sensor 32 is fixedly connected to the bottom of the connecting block 31. An extrusion head 33 is fixedly connected to the bottom of the pressure sensor 32. A control box 34 with an internal touch screen is fixedly connected to one side of the gantry frame 2. When the lifting plate 9 descends, it drives the connecting block 31. The connecting block 31 drives the extrusion head 33 through the pressure sensor 32. The extrusion head 33 applies pressure to the asphalt body 6 on the operating platform 5. At the same time, the pressure sensor 32 monitors the pressure value and transmits the detection data to the inside of the control box 34 until the asphalt body 6 breaks, thereby achieving the purpose of detecting the hardness of the asphalt body 6.

[0033] like Figure 1 and Figure 2 As shown, each of the four corners of the lifting plate 9 is slidably connected with a sliding rod 35. The two ends of the sliding rod 35 are fixedly connected to the gantry frame 2 and the base plate 1, respectively, which can limit the lifting plate 9 and enable the lifting plate 9 to move vertically.

[0034] Working principle: The user places the asphalt body 6 on the operating table 5, and then rotates the knob 28. The knob 28 drives the bidirectional screw 27 to rotate. As the bidirectional screw 27 rotates, it drives the threaded blocks 26 on both sides to move closer together. As the threaded blocks 26 move closer together, they also drive the clamping blocks 25, thereby making the two clamping blocks 25 cooperate to clamp and fix the asphalt body 6. This clamps the asphalt sample and prevents it from rolling or shifting during hardness testing, which could lead to inaccurate hardness test data. The hydraulic cylinder 14 is then activated, and the telescopic end of the hydraulic cylinder 14 moves towards... As the lifting plate 9 extends downwards, it pushes the lifting plate 9 downwards. Simultaneously, the lifting plate 9 pushes the second limiting plate 13 via the first spring 12. The second limiting plate 13 causes the L-shaped rod 10 to move downwards. As the L-shaped rod 10 moves downwards, it presses against the right-angle rod 15, causing the right-angle rod 15 to rotate around the first rotating shaft 16. While rotating, the right-angle rod 15 pulls the cylindrical block 19 via the stroke groove 18. The cylindrical block 19 drives the operating table 5 via the fixed block 20. The operating table 5 slides horizontally on the guide rail 3 via the moving block 4. While sliding, the operating table 5 drives the asphalt body 6, thereby transporting the asphalt body 6... As the right-angle rod 15 rotates to the bottom plate 1 near the end of the L-shaped rod 10, the telescopic end of the hydraulic cylinder 14 continues to push the lifting plate 9 downward. At this time, the L-shaped rod 10 is stationary, and the lifting plate 9 continues to slide downward on the surface of the L-shaped rod 10. As the lifting plate 9 descends, it drives the connecting block 31. The connecting block 31 drives the extrusion head 33 through the pressure sensor 32. The extrusion head 33 applies pressure to the asphalt body 6 on the operating table 5. While applying pressure, the pressure sensor 32 monitors the pressure value and transmits the detection data to the inside of the control box 34 until the asphalt body 6 breaks. This achieves the purpose of testing the hardness of asphalt itself. It not only tests the hardness of asphalt samples, improving its practicality, but also automatically pushes the asphalt sample into the device, avoiding accidental contact and injury to workers who manually place the asphalt sample into the device, thus improving safety. Although existing modified asphalt testing devices containing active compatibilizers can test and compare the hardness of asphalt samples, as asphalt is generally used for road construction, which requires high hardness. Existing devices do not have the ability to test the hardness of asphalt, resulting in poor practicality.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
