Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of asphalt detection, in particular to an asphalt mixture compaction degree detection device. Background Art
[0002] Compaction degree is one of the key indicators for testing the quality of roadbed and pavement construction. It characterizes the density condition after on-site compaction. The higher the compaction degree, the greater the density and the better the overall performance of the material. Asphalt mixtures are required for roads in water conservancy projects and some paved surfaces. The compaction degree of the asphalt mixture needs to be tested after compaction.
[0003] In the current existing technology, before asphalt is laid on the road, in order to test the compaction of the asphalt, a ball of asphalt is randomly sampled and placed on a detector for compaction testing. To ensure the accuracy of the asphalt compaction data, it is necessary to wait for the asphalt to completely solidify before testing. However, asphalt is a high-viscosity organic liquid, mostly existing in the form of liquid or semi-solid petroleum. The solidification rate of asphalt after heating and melting is very slow. It takes 24 hours for the asphalt surface to completely harden. If you need to wait for the asphalt to completely solidify, it will take 3-5. The waiting time is too long, which will waste a lot of time and affect the work progress.
[0004] Therefore, in order to solve the above problems, an asphalt mixture compaction detection device is proposed. Utility Model Content

[0014] The utility model provides an asphalt mixture compaction detection device. When working, after the height of the lower pressure plate is moved up to the top position of the air guide pipe under the push of a hydraulic telescopic rod, the circulating air guide is cooperated with to push the high-temperature and high-pressure airflow into the air guide pipe, so that the hot air is concentrated in the interior of the processing table.

[0027] During operation, the lower pressure plate 116 is moved to the top position of the air duct 131 under the push of the hydraulic telescopic rod 115, and the circulating air guide 13 is used to push high-temperature and high-pressure airflow into the air duct 131, so that the hot air is concentrated inside the processing table 11. The air guide inclined groove 132 on one end of the air duct 131 is used to make the hot air flow entering the processing table 11 present a downward blowing angle. When the hot air flow hits the asphalt surface, the high temperature, high pressure and high-speed air flow are used to promote the rapid volatilization of the solvent inside the asphalt. At the same time, the circulating air guide 13 is used to circulate the air flow inside the processing table 11, so that the hot air flow inside the processing table 11 can always be maintained in a high-temperature and high-pressure environment. The circulating air flow can also be used to accelerate the rapid volatilization of the solvent inside the asphalt, so that the asphalt can be quickly condensed and solidified under a high-temperature and high-pressure environment and can be used normally, which greatly speeds up the use time of the asphalt.
[0028] Further, such as Figures 1 to 6 As shown, a slide groove 111 is provided on the top surface of the processing table 11 and is movably connected to the bottom surface of the asphalt compacting box 12. Motors 112 with threads that are movably connected to the two side surfaces of the asphalt compacting box 12 are provided on the inner wall surfaces on both sides of the processing table 11. A closing cover 113 is movably connected to the edge position of one side of the top of the processing table 11. A hydraulic telescopic rod 117 is fixedly installed on the two side surfaces of the processing table 11 and located at the edge position of one side. The output end of the hydraulic telescopic rod 117 is fixedly connected to a downward pressure detector 118 that is movably overlapped on the inner wall surface of the asphalt compacting box 12.
[0029] During operation, the asphalt ball is placed into the asphalt compacting box 12, and the asphalt compacting box 12 is moved by the slide 111. After the asphalt compacting box 12 moves to a suitable position, the lower pressure plate 116 is pressed down by the hydraulic telescopic rod 115 to flatten and compact the asphalt inside the asphalt compacting box 12, thereby increasing the sealing and adhesion of the asphalt in the middle. The lower pressure plate 116 is then moved upward to the top position of the air duct 131 by the hydraulic telescopic rod 115, and the entrance of the processing table 11 is closed by the closing cover 113 at the same time. The interior of the processing table 11 is subjected to circulating high-temperature and high-pressure treatment by the circulating air guide 13, and the continuous circulation of the hot air flow is used to accelerate the rapid volatilization of the solvent inside the asphalt.
[0030] Further, such as Figures 1 to 6 As shown, an elastic wire 124 is fixedly connected to the top outer surface of the asphalt compacting box 12, and a push plate 125 movably sleeved on the inner wall of the asphalt compacting box 12 is fixedly connected to the top of the elastic wire 124. A limiting sleeve 123 is staggered and fixedly connected on the top surface of the asphalt compacting box 12 and the bottom surface of the push plate 125. A limiting groove 121 is provided on the top surface of the asphalt compacting box 12 and at one side edge position, and a closing plate 122 is movably sleeved on the inner wall of the limiting groove 121.
[0031] During operation, when the asphalt is ready for use, the asphalt is moved out in conjunction with the asphalt compacting box 12, and the natural wind is used to cool the asphalt. After cooling, the asphalt will shrink in a small range. At this time, the elastic wire 124 on the bottom surface of the asphalt compacting box 12 is used to push the push plate 125 upward, so that the edges of the asphalt are separated from the middle of the inner wall of the asphalt compacting box 12. When the push plate 125 moves upward, the limit sleeve 123 is used to increase the upward angle of the push plate 125 in a vertical state, and then the hydraulic telescopic rod 117 is used to lower the downward pressure detector 118 to squeeze the surface of the asphalt, and the downward pressure detector 118 is used to detect the compaction degree of the asphalt.
[0032] Working principle: put the asphalt ball into the asphalt compacting box 12, cooperate with the slide 111 to move the asphalt compacting box 12, and after the asphalt compacting box 12 moves to the appropriate position, cooperate with the hydraulic telescopic rod 115 to press down the lower pressure plate 116 to flatten and compact the asphalt inside the asphalt compacting box 12, thereby increasing the sealing and adhesion of the asphalt in the middle. Then, the hydraulic telescopic rod 115 is used to move the lower pressure plate 116 upward to the top position of the air guide 131, and at the same time cooperate with the closing cover 113 to seal the entrance of the processing table 11. Cooperate with the circulating air guide 13 to perform circulating high temperature and high pressure treatment on the interior of the processing table 11, and use the continuous circulation of hot air flow to accelerate the rapid volatilization of the solvent inside the asphalt.
[0033] After the lower pressure plate 116 is moved to the top position of the air guide pipe 131 under the push of the hydraulic telescopic rod 115, the circulating air guide 13 is used to push the high-temperature and high-pressure airflow into the air guide pipe 131, so that the hot air is concentrated in the interior of the processing table 11. The air guide inclined groove 132 on one end of the air guide pipe 131 is used to make the hot air flow entering the processing table 11 present a downward blowing angle. When the hot air flow hits the asphalt surface, the high temperature, high pressure and high-speed air flow are used to promote the rapid volatilization of the solvent in the asphalt. At the same time, the circulating air guide 13 is used to circulate the air flow inside the processing table 11, so that the hot air flow inside the processing table 11 can always be maintained in a high-temperature and high-pressure environment. The circulating airflow can also be used to accelerate the rapid volatilization of the solvent in the asphalt, so that the asphalt can be quickly condensed and solidified under the high-temperature and high-pressure environment and can be used normally, which greatly shortens the service life of the asphalt.
[0034] When the asphalt is ready for use, the asphalt is moved out in conjunction with the asphalt compaction box 12, and the asphalt is cooled by natural wind. After cooling, the asphalt will shrink in a small range. At this time, the elastic wire 124 on the bottom surface of the asphalt compaction box 12 is used to push the push plate 125 upward, so that the edges of the asphalt are separated from the middle of the inner wall of the asphalt compaction box 12. When the push plate 125 moves upward, the limit sleeve 123 is used to increase the upward angle of the push plate 125 in a vertical state, and then the hydraulic telescopic rod 117 is used to lower the downward pressure detector 118 to squeeze it on the surface of the asphalt, and the downward pressure detector 118 is used to detect the compaction degree of the asphalt.
