Specific embodiments
[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0020] Such as Figures 1-4As shown in the figure, the utility model provides a technical solution: a water spraying test device for asphalt concrete production, which includes a fixing plate 1. Asphalt concrete 2 is laid on the top end of the fixing plate 1. A number of filter holes 101 are opened on the top end of the fixing plate 1. An outer cover 3 is threadedly connected to the top end of the fixing plate 1. A water spraying mechanism is provided between the outer top end and the inner top end of the outer cover 3. A transmission mechanism for controlling the rotation of the water spraying mechanism is provided between the outer end of the water spraying mechanism and the outer top end of the outer cover 3. A water receiving tank 6 is threadedly connected to the bottom end of the fixing plate 1. By taking a partial sample of the produced asphalt concrete 2 and laying it on the fixing plate 1, when the asphalt concrete 2 is cured, the outer cover 3 is threadedly connected to the top end of the fixing plate 1, and the water receiving tank 6 is threadedly connected to the bottom end of the fixing plate 1. Through the settings of the water spraying mechanism and the transmission mechanism, it is convenient to conduct a water resistance and water permeability test on the cured asphalt concrete 2. Through the settings of the water receiving tank 6 and the filter holes 101 at the top end of the fixing plate 1, it is possible to conveniently collect the dripping water. According to the observed amount of collected water, it can be detected whether the water resistance of the asphalt concrete 2 is qualified. Through the setting of the transmission mechanism, it is convenient to adjust the size of the water spraying, so that a simulation test of various weather conditions can be carried out on the asphalt concrete 2 according to the size of the water spraying amount, improving the practicability of the water spraying test device. At the same time, it is convenient to conduct a water resistance test on the asphalt concrete 2 before it is laid on the road, thus preventing the laying of asphalt concrete 2 with unqualified water resistance on the road and avoiding problems such as low ground service life and easy cracking caused by the laying of asphalt concrete 2 with unqualified water resistance on the road.
[0021] As an implementation method in this embodiment, as Figure 1 and Figure 2As shown in the figure, the water spraying mechanism includes a first conical pipe 4. The first conical pipe 4 is rotatably arranged at the top end of the outer cover 3. The inside of the first conical pipe 4 is hollow. The top end of the first conical pipe 4 is fixedly connected with a water tank 401. The top end of the water tank 401 is threadedly connected with a water injection cover. Opening the water injection cover can add water to the water tank 401. The bottom end of the water tank 401 is fixedly connected with a second conical pipe 402. The second conical pipe 402 is inserted into the first conical pipe 4. The inside of the first conical pipe 4 is communicated with the inside of the water tank 401, which is convenient for the water in the water tank 401 to flow into the inside of the first conical pipe 4. A plurality of first water outlet holes 406 are opened at the bottom end and the side end of the first conical pipe 4, which is convenient for water outlet. The top end inside the outer cover 3 is fixedly connected with a sleeve 405. The sleeve 405 is sleeved on the outer end of the first conical pipe 4. A plurality of second water outlet holes 407 are opened at the bottom end and the side end of the sleeve 405. During implementation, when the first water outlet holes 406 at the bottom end and the side end of the first conical pipe 4 coincide with the second water outlet holes 407 at the bottom end and the side end of the sleeve 405, the water in the water tank 401 will flow out from the first conical pipe 4 through the first water outlet holes 406 and the second water outlet holes 407. At this time, it is convenient to conduct a water resistance and water permeability test on the solidified asphalt concrete 2. Through the settings of the water receiving tank 6 and the filter holes 101 at the top end of the fixing plate 1, it is possible to conveniently collect the dripping water. According to the observed amount of collected water, it can be detected whether the water resistance of the asphalt concrete 2 is qualified, which is convenient for conducting a water resistance test on the asphalt concrete 2 before it is laid on the road, thereby avoiding laying the asphalt concrete 2 with unqualified water resistance on the road and preventing the ground service life from being low and being prone to cracking due to the laying of the asphalt concrete 2 with unqualified water resistance on the road.
[0022] As an implementation method in this embodiment, as Figure 1 and Figure 3 shown, the transmission mechanism includes an external gear ring 403. The external gear ring 403 is fixedly connected to the outer end of the water tank 401. A slide rail 301 is opened at the top end of the outer cover 3. A plurality of slide rods 404 are fixedly connected to the bottom end of the external gear ring 403. The plurality of slide rods 404 are slidably connected in the slide rail 301. The top end outside the outer cover 3 is fixedly connected with a motor 5. A rotating rod 501 is installed at the output end of the motor 5. A gear 502 is fixedly connected to the top end of the rotating rod 501. The gear 502 meshes with the external gear ring 403. During implementation, starting the motor 5 drives the rotating rod 501 and the gear 502 to rotate. At this time, the gear 502 meshes with the external gear ring 403 to drive the water tank 401 to rotate. At this time, the rotation of the water tank 401 drives the first conical pipe 4 and the second conical pipe 402 to rotate. When the first water outlet holes 406 at the bottom end and the side end of the first conical pipe 4 gradually no longer coincide with the second water outlet holes 407 at the bottom end and the side end of the sleeve 405, this process is convenient for adjusting the size of the water spray, so that various weather conditions can be simulated for testing the asphalt concrete 2 according to the size of the water spray amount, improving the practicability of the water spray testing equipment.
[0023] Working principle: Take a part of the produced asphalt concrete 2 as a sample and lay it on the fixed plate 1. After the asphalt concrete 2 is cured, thread-connect the outer cover 3 to the top of the fixed plate 1 and thread-connect the water receiving tank 6 to the bottom of the fixed plate 1. At this time, start the motor 5 to drive the rotating rod 501 and the gear 502 to rotate. At this time, the gear 502 meshes with the external gear ring 403 to drive the water tank 401 to rotate. At this time, the rotation of the water tank 401 drives the conical pipe 1 4 and the conical pipe 2 402 to rotate. At this time, when the water outlet holes 1 406 at the bottom and side of the conical pipe 1 4 coincide with the water outlet holes 2 407 at the bottom and side of the sleeve 405, the water in the water tank 401 will flow out from the conical pipe 1 4 through the water outlet holes 1 406 and the water outlet holes 2 407. At this time, it is convenient to conduct a water resistance and water permeability test on the cured asphalt concrete 2. Through the settings of the water receiving tank 6 and the filter holes 101 at the top of the fixed plate 1, it is possible to facilitate the collection of the dripping water. According to the observed amount of collected water, it can be detected whether the water resistance of the asphalt concrete 2 is qualified. When the conical pipe 1 4 and the conical pipe 2 402 continue to rotate, when the water outlet holes 1 406 at the bottom and side of the conical pipe 1 4 gradually no longer coincide with the water outlet holes 2 407 at the bottom and side of the sleeve 405, this process is convenient for adjusting the size of the water spray, so that various weather conditions can be simulated for the asphalt concrete 2 according to the size of the water spray amount, improving the practicability of the water spray test equipment. At the same time, it is convenient to conduct a water resistance test on the asphalt concrete 2 before it is laid on the road, thus preventing the laying of asphalt concrete 2 with unqualified water resistance on the road, and preventing the low service life and easy cracking of the ground caused by the laying of asphalt concrete 2 with unqualified water resistance on the road.
