Technical Field

[0001] This utility model relates to the field of road engineering testing equipment technology, and in particular to an emulsified asphalt adhesion strength testing machine. Background Technology

[0002] In highway construction, emulsified asphalt is widely used in construction processes such as prime coats, seal coats, and cold recycled mixtures. Its bonding performance with aggregates directly affects the durability and shear strength of the pavement. Therefore, accurately measuring the bond strength between emulsified asphalt and aggregates is of great significance.

[0003] However, in existing technologies, conventional testing methods often involve manual pull-out testing in conjunction with a universal testing machine. Furthermore, the platform on which the material is placed needs to be frequently cleaned to prevent dust or impurities from entering the material and affecting the accuracy of subsequent measurements. In addition, manual operation is cumbersome, has poor repeatability, and results in low measurement efficiency. Therefore, a solution is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art: conventional testing methods often use manual pull-out combined with a universal testing machine for measurement, and the platform on which the material is placed needs to be frequently treated to prevent dust or impurities from adhering to the material and filling the inside of the material, which would affect the accuracy of subsequent measurements. At the same time, manual operation is cumbersome, has poor repeatability, and results in low measurement efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an emulsified asphalt adhesion strength testing machine, comprising: a workbench, a holding platform, disposed on the inner wall of the workbench; and further comprising:

[0006] A drainage channel is formed on the surface of the workbench and is arranged around the holding platform;

[0007] A cleaning structure is provided on the inner wall of the workbench, the cleaning structure comprising:

[0008] Two slots are formed on the inner wall of the workbench at symmetrical locations, and a guide rod is fixedly installed on the inner wall of one of the slots;

[0009] A stepper motor is fixedly mounted on the outer surface of the workbench via a frame, and the output end of the stepper motor is provided with a threaded rod.

[0010] Preferably, a movable plate is threaded onto the outer surface of the threaded rod, and one end of the movable plate is movably fitted onto the outer surface of the guide rod.

[0011] The technical effect of adopting the above-mentioned further solution is that when the threaded rod rotates, it drives the moving plate on the outer surface to slide laterally along the surface of the guide rod.

[0012] Preferably, a sliding rod is fixedly provided on the inner wall of the symmetrical part of the movable plate, and a connecting block is slidably sleeved on the surface of the two sliding rods.

[0013] The technical effect of adopting the above-mentioned further solution is that the connecting block is positioned by the sliding rod on the inner wall of the moving plate.

[0014] Preferably, the two connecting blocks are slidably embedded in the inner wall of the movable plate, and a spring is fixedly provided on one side surface of the two connecting blocks.

[0015] The technical effect of adopting the above-mentioned further solution is that the moving plate provides a limiting function for the connecting block, and at the same time positions the spring on the surface.

[0016] Preferably, one end of each of the two springs is fixedly mounted on the inner wall of the movable plate, and the two connecting blocks are connected by a scraper.

[0017] The technical effect of adopting the above-mentioned further solution is that: by means of one end of the spring being connected to the inner wall of the moving plate, the connecting block is reset, and at the same time the connecting block fixes the scraper.

[0018] Preferably, the top surface of the movable plate is threaded with a long bolt, one end of which is movably connected to the surface of the scraper.

[0019] The technical effect of adopting the above-mentioned further solution is that when the long bolt inside the rotating moving plate is rotated, the scraper connected to the surface is moved at a certain height.

[0020] Preferably, a hydraulic cylinder is fixedly installed on the top surface of the workbench, and a mounting plate is installed at the output end of the hydraulic cylinder.

[0021] The technical effect of adopting the above-mentioned further solution is that when the hydraulic cylinder is working, it drives the mounting plate at the output end to adjust its position up and down.

[0022] Preferably, a tension gauge is detachably mounted on the surface of the first mounting plate, and a second mounting plate is mounted on the bottom of the tension gauge.

[0023] The technical advantage of adopting the above-mentioned further solution is that the installation work is provided by a pair of tension gauges through the mounting plate, and the installation is carried out with the asphalt raw material after the aggregate by means of the second mounting plate, which facilitates the subsequent testing.

[0024] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0025] 1. In this utility model, by rotating the long bolt, the connecting block of the contact surface of the connected scraper slides up and down along the surface of the slide rod. The stepper motor is started to work, so that the threaded rod drives the surface moving plate to move laterally along the surface of the guide rod. With the help of the scraper, it contacts the holding platform and works with the water spraying equipment to clean its surface, preventing impurities on the surface from filling into the asphalt material and affecting the accuracy of subsequent measurements.

[0026] 2. In this utility model, the long bolt is rotated again, and the spring and connecting block provide a reset function, thereby adjusting the distance between the scraper and the holding platform. The emulsified asphalt material is placed on the surface of the holding platform, and the stepper motor is started again to make the emulsified asphalt material evenly spread on the surface of the holding platform. While the emulsified asphalt is not dry, a layer of standard aggregate is attached to its surface and gently pressed to partially embed it into the emulsified asphalt, which facilitates later measurement. At the same time, multiple measurements can be taken according to the thickness of the emulsified asphalt coating. Finally, the hydraulic cylinder works to move the tension gauge on the surface of the output end mounting plate one downward. With the help of the mounting plate two and the aggregate on the surface of the emulsified asphalt, it is fixed by clamping or other methods. With the reverse movement of the hydraulic cylinder, the cured emulsified asphalt material is pulled, and the peel strength is measured by the tension gauge. This makes the operation convenient and reduces the risk of injury to the measuring personnel caused by material breakage during the pulling process. Attached Figure Description

[0033] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0035] Example 1, such as Figure 1-4 As shown, this utility model provides an emulsified asphalt adhesion testing machine, including: a workbench 1 on which a holding platform 102 is provided for placing asphalt samples; a drainage groove 101 is formed around the holding platform 102 on the surface of the workbench 1 to collect liquid residue during the testing process, so as to avoid contaminating the equipment or affecting the accuracy of the test data; and a cleaning structure is provided inside the workbench 1, including symmetrically arranged slots 1011, guide rods 1012 and threaded rods 1013 driven by stepper motors 1014, to realize automatic cleaning of the equipment surface.

[0036] In this embodiment, by rotating the long bolt 1035, the connecting block 1033 of the contact surface of the connected scraper 1034 slides up and down along the surface of the slide rod 1031. The stepper motor 1014 is started, so that the threaded rod 1013 drives the surface moving plate 103 to move laterally along the surface of the guide rod 1012. With the help of the scraper 1034, it contacts the holding platform 102 and works with the water spraying equipment to clean its surface, preventing impurities on the surface from filling into the asphalt material and affecting the accuracy of subsequent measurements.

[0037] Example 2, as Figure 1-4 As shown, the moving plate 103, driven by the threaded rod 1013, moves linearly along the guide rod 1012, driving the cleaning assembly to complete the flattening of the sample surface; the scraper 1034 achieves vertical elastic floating through the connecting block 1033 and the sliding rod 1031, ensuring uniform force during scraping; it is also equipped with a height adjustment bolt 1035 for quick adjustment according to samples of different thicknesses; the testing section is driven by the hydraulic cylinder 104 to move the mounting plate 1041 downward, and the loading system composed of the tensile gauge 1042 and the mounting plate 1043 applies tensile force to the sample, thereby determining the bonding strength between the emulsified asphalt and the substrate.

[0038] In this embodiment, the long bolt 1035 is rotated again, and the spring 1032 and connecting block 1033 provide a reset, thereby adjusting the distance between the scraper 1034 and the holding platform 102. The emulsified asphalt material is placed on the surface of the holding platform 102, and the stepper motor 1014 is started again to make the emulsified asphalt material evenly spread on the surface of the holding platform 102. While the emulsified asphalt is not dry, a layer of standard aggregate is attached to its surface and gently pressed to partially embed it into the emulsified asphalt, which is convenient for later measurement. At the same time, multiple measurements can be taken according to the thickness of the emulsified asphalt coating. Finally, the hydraulic cylinder 104 is operated to move the tension gauge 1042 on the surface of the output end mounting plate 1041 downward. With the help of the mounting plate 2 1043 and the aggregate on the surface of the emulsified asphalt, it is fixed by clamping or other methods. With the reverse movement of the hydraulic cylinder 104, the cured emulsified asphalt material is pulled, and the peel strength is measured by the tension gauge 1042. This makes the operation convenient and reduces the risk of injury to the measuring personnel caused by material breakage during the pulling process.

[0039] Working principle: During use, rotating the long bolt 1035 causes the connecting block 1033 on the contact surface of the connected scraper 1034 to slide up and down along the surface of the slide rod 1031. This activates the stepper motor 1014, causing the threaded rod 1013 to drive the surface moving plate 103 to move laterally along the surface of the guide rod 1012. The scraper 1034 then contacts the holding platform 102, and a water spray device cleans the surface to prevent impurities from filling the asphalt material and affecting the accuracy of subsequent measurements. Simultaneously, rotating the long bolt 1035 again uses the spring 1032 and the connecting block 1033 to reset the scraper 1034, thus adjusting the distance between the scraper 1034 and the holding platform 102, allowing the emulsified asphalt material to be placed on the surface of the holding platform 102. On the surface, the stepper motor 1014 is started again, so that the emulsified asphalt material is evenly spread on the surface of the holding platform 102. While the emulsified asphalt is not dry, a layer of standard aggregate is attached to its surface and gently pressed to partially embed it into the emulsified asphalt, which is convenient for later measurement. At the same time, multiple measurements can be taken according to the thickness of the emulsified asphalt. Finally, the hydraulic cylinder 104 works to move the tension gauge 1042 on the surface of the output end mounting plate 1041 downward. With the help of the mounting plate 1043 and the aggregate on the surface of the emulsified asphalt, it is fixed by clamping and other methods. With the help of the hydraulic cylinder 104 moving in the opposite direction, the cured emulsified asphalt material is pulled. The tensile gauge 1042 is used to measure the peel strength, which makes the operation convenient and reduces the risk of injury to the measuring personnel caused by the material breaking during the pulling process.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
