[0002] Asphalt mixture is a composite material, mainly composed of asphalt, coarse aggregate, fine aggregate, mineral powder, and some also add polymers and wood cellulose; different structures are formed by mixing these materials with different qualities and quantities, and they have different mechanical properties. Asphalt mixture is mainly used for road paving. With the driving of vehicles, the road surface will be damaged, especially severely damaged in case of braking. Therefore, before paving asphalt mixture, experiments on the ruts shown on the material by simulating the braking conditions in different environments are usually required, and a rut testing machine is needed.

Specific embodiments

[0022] 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. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-5 shown, the present utility model provides a technical solution: a rut tester for multi-environment simulation, including a body 1, a display screen 2 and an operation panel 3 are fixedly connected to the front side of the body 1 near the right side, a cavity is provided on the left side of the body 1, a tank body 6 is arranged in the cavity, and the tank body 6 is slidably connected to the bottom of the cavity. A first cylinder 9 is fixedly connected to the top of the tank body 6, the telescopic end of the bottom of the first cylinder 9 is fixedly connected to a U-shaped fixing plate 17, a roller 12 is movably connected to the inner side of the fixing plate 17, a motor 18 is fixedly connected to the outer side of the fixing plate 17, and the output shaft of the motor 18 is fixedly connected to the roller 12. A brake pad 20 is arranged on the inner side of the fixing plate 17, and a second cylinder 19 is fixedly connected between the hand-held piece and the fixing plate 17. A spray pipe 14 and a heating plate 13 are arranged in the cavity, and a nozzle is fixedly connected to the bottom of the spray pipe 14.

[0024] According to the overall structure of the device, during use, open the movable door 4, move the tank body 6 out through the electric slide rail 7, load asphalt materials into the tank body 6, then move the tank body 6 into the cavity, and then start the first cylinder 9. The first cylinder 9 moves downward to make the roller 12 contact the material, and the motor 18 drives the roller 12 to rotate. At this time, the electric slide rail 7 makes the tank body 6 continuously move. Start the second cylinder 19 to push the brake pad 20 to contact the roller 12 for braking, so as to produce ruts on the material. During the test, spray water mist through the spray pipe 14 and heat through the heating plate 13, so as to adjust the humidity in the cavity and the material temperature, simulate different environments, and improve the test accuracy.

[0025] As shown Figure 1 , 2 in the figure, the front side of the cavity is provided with an opening, and a movable door 4 is movably connected to the opening through a hinge. The bottom of the cavity is fixedly connected with an electric slide rail 7, and the groove body 6 is connected to the slider of the electric slide rail 7.

[0026] The electric slide rail 7 is used to move the groove body 6, so that a relative movement is generated between the groove body 6 and the roller 12, and thus ruts can be generated. Moreover, the electric slide rail 7 facilitates the entry and exit of the groove body 6 into and out of the cavity, thereby facilitating the addition and removal of materials.

[0027] As shown Figure 2 in the figure, the spray pipe 14 is fixedly connected to the side wall of the cavity. The nozzle is an atomizing nozzle. The heating plate 13 is fixedly connected to the bottom of the groove body 6. A plurality of through holes are formed in the groove body 6, and the through holes are bent.

[0028] The water in the spray pipe 14 is sprayed out in the form of water mist through the atomizing nozzle, which can quickly adjust the humidity environment. The heating plate 13 can quickly transfer heat to increase the temperature of the material. At the same time, the through holes can connect to the external water pipe, allowing cold water from the outside to flow through, so as to facilitate the cooling of the material, thereby adjusting the temperature.

[0029] As shown Figure 2 in the figure, a tubular pressure roller 8 is provided near the front side of the cavity. A U-shaped connecting plate 11 is sleeved outside the pressure roller 8, and the pressure roller 8 is movably connected to the connecting plate 11, and the connecting plate 11 is connected to the top of the cavity.

[0030] The pressure roller 8 is used to flatten the material, making the surface of the material flat, and avoiding unevenness on the surface caused by unevenness when the material is poured, which may affect the test results.

[0031] As shown Figure 5 in the figure, rectangular grooves are formed on both sides of the connecting plate 11. Both ends of the pressure roller 8 are movably connected with screw rods 21, and the screw rods 21 pass through the adjacent rectangular grooves and are threadedly connected with nuts 15.

[0032] The nut 15 can be unscrewed through the threaded connection, so that the screw rod 21 is loose from the connecting plate 11, and thus the height of the pressure roller 8 can be adjusted, so as to facilitate the compaction of the material to different degrees, increase the detection environment, and improve the test accuracy.

[0033] As shown Figure 2 in the figure, a bottom plate 16 is provided at the bottom of the groove body 6, and the bottom plate 16 is fixedly connected to the slider of the electric slide rail 7. Third cylinders 10 are movably connected between the top of the connecting plate 11 near both ends and the top of the cavity. Third cylinders 10 are also movably connected between the bottom of the groove body 6 and the bottom plate 16 near the four corners.

[0034] The angle of the trough body 6 and the pressure roller 8 can be adjusted by the third cylinder 10, so that the rutting conditions at different angles can be tested.

[0035] As Figure 1 shown, an opening is provided on the movable door 4, and a glass plate 5 is fixedly connected inside the opening.

[0036] The cavity is closed by the movable door 4 to separate the environment inside the cavity from the outside world and avoid being affected by the external environment. The inside of the cavity can be observed through the glass plate 5.

[0037] Working principle: When in use, connect the device to an external power supply, open the movable door 4, move the trough body 6 out through the electric slide rail 7, load asphalt materials into the trough body 6, and then move the trough body 6 into the cavity. During the process of moving the trough body 6 in, the material is flattened by the pressure roller 8 to make the surface of the material flat. Then start the first cylinder 9. The first cylinder 9 moves downward so that the roller 12 contacts the material, and the motor 18 drives the roller 12 to rotate. At this time, the electric slide rail 7 makes the trough body 6 continue to move. Start the second cylinder 19 to push the brake pad 20 to contact the roller 12 for braking, and ruts are generated on the material for testing. During the test, water mist is sprayed through the spray pipe 14 to adjust the humidity inside the cavity, the heating plate 13 is started for heating to increase the temperature of the material, water is transported into the through hole to cool the material and reduce the temperature of the material, so as to simulate different environments. The trough body 6 can be tilted at different angles by the third cylinder 10 to simulate different road surface angles.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
