Abstract
Description
Technical Field
[0001] This application relates to the technical field of material wear resistance testing equipment, and particularly to a wear resistance testing equipment for micro-surfacing mixture. Background Art
[0002] The length of asphalt roads in China has reached the first in the world. Various diseases often occur in the initial stage of asphalt pavement use. If effective measures are not taken in time, the road surface will be more seriously damaged, which will not only deteriorate the highway service quality, but also easily lead to various traffic accidents. Among them, micro-surfacing is a widely used asphalt pavement maintenance solution with a short construction period and good treatment effect, which can effectively improve various indexes such as anti-skid, anti-seepage, and flatness of the road surface. Micro-surfacing uses stone chips or sand, fillers, polymer modified emulsified asphalt, admixtures and water to be mixed into a flowing mixture in a certain proportion, and then evenly spread on the seal layer of the road surface. In order to detect the water damage resistance performance of the mixture, it is necessary to conduct a 6D immersion wet wheel abrasion test on the mixture. In this test, it is required that the water surface height in the sample tray needs to be more than 6 mm higher than the upper end face of the sample. Due to the long experimental time, with the splashing and evaporation of water, the water surface will continuously drop, and it is necessary for the testers to add water regularly. When there are many experimental devices, the staff is prone to negligence, resulting in too low water surface height in the sample tray, affecting the test results. Therefore, a wear resistance testing equipment for micro-surfacing mixture is needed, which is provided with a structure that can automatically replenish water. When the water surface in the sample tray is too low, it can automatically replenish water without the need for testers to check regularly, reducing the experimental result error caused by human factors and ensuring the accuracy of the test results. Content of the Utility Model

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the said features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
[0019] As Figures 1 to 3 shown, an embodiment of the present utility model provides a micro-surfacing mixture abrasion test device, including: a base 1, a top plate 2, a lifting table 3, a water storage tank 4, and a sample tray 5. The upper part of the base 1 is connected to the top plate 2 through a connecting column 6. One side of the lifting table 3 is connected to the connecting column 6 through a sleeve 7. The sample tray 5 is connected to the lifting table 3 through a second locking nut 9. A first support frame 10 is provided on the top plate 2, and the water storage tank 4 is installed on the first support frame 10. The upper part of the water storage tank 4 is sealed, and a sealing cover 11 is provided at the lower part of the water storage tank 4. A first hard pipe 12 is connected to the sealing cover 11. A second hard pipe 13 is provided on the lifting table 3. The middle part of the second hard pipe 13 is connected to the lifting table 3 through a second support frame 14, and the upper end of the second hard pipe 13 is connected to the lower end of the first hard pipe 12 through a rubber hose 15. The lower end of the second hard pipe 13 vertically extends into the sample tray 5.
[0020] After the water storage tank 4 is filled with water, screw on the sealing cap 11. Then, pass the first rigid tube 12 through the top plate 2 and connect it to the rubber tube 15 through the quick connector 19. Subsequently, install the sample tray 5 containing the test sample, and adjust the height of the lifting platform 3 so that the height of the sample and the grinding disc is appropriate. Then, lock the first locking nut 8 to fix the position of the lifting platform 3. Then, loosen the nut on the second rigid tube 13 and adjust the distance between the lower end of the second rigid tube 13 and the sample. After the adjustment is completed, tighten the nut. Subsequently, open the valve 18 on the first rigid tube 12. At this time, since there is no water in the sample tray 5, the water in the water storage tank 4 flows out under the action of gravity and enters the sample tray 5. At the same time, air enters the water storage tank 4 along the second rigid tube 13, the rubber tube 15, and the first rigid tube 12 to ensure the air pressure balance inside the water storage tank 4. As the water continuously flows out, the liquid level in the sample tray 5 continuously rises. When the liquid level is higher than the lower end of the second rigid tube 13, at this time, the outside air cannot enter the water storage tank 4 through the second rigid tube 13, causing a negative pressure area to form in the upper part of the water storage tank 4, thereby preventing the water inside the water storage tank 4 from flowing out. After starting the motor, the motor drives the grinding disc to rotate and tests the test sample. As the water splashes or evaporates, the liquid level in the sample tray 5 will continuously drop. When the liquid level is lower than the lower end of the second rigid tube 13, the outside air flow can enter the water storage tank 4 along the pipeline again, causing the water in the water storage tank 4 to flow out. After being higher than the lower end of the second rigid tube 13, the water flow in the water storage tank 4 stops again. Thus, the purpose of automatic water replenishment and liquid level height control is achieved, eliminating the need for testers to regularly check and reducing the experimental result error caused by human factors to ensure the accuracy of the test results.
[0021] In a preferred embodiment, the sample tray 5 contains a test sample, and the distance between the lower end of the second rigid tube 13 and the upper end face of the test sample is 6 mm to 10 mm. By controlling the distance between the lower end of the second rigid tube 13 and the upper end face of the test sample, the water replenishment height of the device can be controlled so that the liquid level height in the sample tray 5 meets the requirements of the experimental manual.
[0022] Preferably, as Figure 3 shown, the outer periphery of the second rigid tube 13 is provided with threads. The second rigid tube 13 passes through the second support frame 14, and the second rigid tube 13 is fixed to the second support frame 14 by two nuts. After loosening the nuts, the height of the second rigid tube 13 in the vertical direction can be adjusted, thereby controlling the water replenishment height of the device by controlling the distance between the lower end of the second rigid tube 13 and the upper end face of the test sample.
[0023] Preferably, as Figure 2 shown, a side stop block 17 is provided on the upper part of the first support frame 10. When the water storage tank 4 is placed on the upper part of the first support frame 10, the side stop block 17 blocks the outer periphery of the water storage tank 4, enabling the water storage tank 4 to be stably placed on the first support frame 10 and preventing the water storage tank 4 from shifting and affecting the operation of the device.
[0024] Preferably, asFigure 2 As shown, the first rigid pipe 12 penetrates the top plate 2 from top to bottom, and a valve 18 is provided in the middle of the first rigid pipe 12 to facilitate the control of the opening and closing of the water flow. The lower end of the first rigid pipe 12 is connected to the rubber hose 15 through a quick connector 19. The quick connector 19 is a commercially available quick connector, so as to quickly connect and disconnect the rubber hose 15 and the first rigid pipe 12.
[0025] In a preferred embodiment, a first locking nut 8 is provided on the sleeve 7. After the first locking nut 8 is tightened, the sleeve 7 can be locked on the connecting column 6 to prevent the lifting table 3 from sliding.
[0026] Of course, the present application may also have many other implementation manners. Based on this implementation manner, other implementation manners obtained by those of ordinary skill in the art without any creative work belong to the scope protected by the present application.
