[0002] Rubberized asphalt is a modified asphalt binder material with properties such as high temperature stability, low temperature flexibility, anti-aging, fatigue resistance, and water damage resistance. It is an ideal environmentally friendly pavement material and is mainly used in stress-absorbing layers and surface layers in road structures.

[0003] Rubberized asphalt is prone to aging under the natural conditions of sunlight, heat, and water on road surfaces. This leads to the gradual degradation of the asphalt mixture, causing cracks and depressions in the pavement, affecting its durability and road performance. However, existing asphalt testing devices, due to their simple structure, can only test asphalt at a fixed angle and cannot adjust multiple surfaces, resulting in inaccurate test results.

[0004] Therefore, a UV aging performance testing device for rubber asphalt mixtures is proposed to solve the problems mentioned above. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1 - Figure 4 The UV aging performance testing device for rubber asphalt mixture in this embodiment includes a UV aging test chamber body 25. A placement mechanism 15 is sleeved on the inner wall of the UV aging test chamber body 25. A baffle 16 is slidably sleeved inside the placement mechanism 15. A groove 17 is opened on the upper end face of the baffle 16. A sliding plate 18 is sleeved on the inner wall of the baffle 16. A first support plate 12 is fixedly installed on the front of the UV aging test chamber body 25. A telescopic cylinder 21 is fixedly installed on the upper end face of the first support plate 12. A first moving plate 11 is fixedly installed on the outer arc-shaped surfaces on both sides of the telescopic end of the telescopic cylinder 21. The surfaces of the two first movable plates 11 are rotatably fitted with movable plates 10. The ends of the movable plates 10 are rotatably connected to the second movable plates 9. The opposite sides of the second movable plates 9 are fixedly installed with connecting rods. The inner wall of the UV aging test chamber body 25 is fixedly installed with a lamp device 7. The inner wall of the UV aging test chamber body 25 is fixedly installed with a spray mechanism 6. The inner wall of the spray mechanism 6 is fixedly connected with a water supply pipe 4. A flow meter 5 is fixedly installed on one section of the water supply pipe 4. A water pump 3 is fixedly installed at the bottom end of the water supply pipe 4. A controller 24 is fixedly installed on the front of the UV aging test chamber body 25.

[0025] By setting a telescopic cylinder 21, when the telescopic cylinder 21 drives the first moving plate 11 to move up and down, it can drive the movable plate 10 to flip, so that the movable plate 10 can drive the second moving plate 9 to achieve the flipping of the fluorescent ultraviolet lamp 8, complete multi-angle adjustment, and improve the comprehensiveness of rubber asphalt irradiation. At the same time, the telescopic cylinder 21 is set to model MXQ, and the controller 24 can issue commands to realize the decision-making function. The controller 24 is set to model JY-DTD-G01A.

[0026] Among them, the water tank 1 is fixedly installed at the water inlet end of the water pump 3, and the water inlet pipe 2 is fixedly installed on the upper end face of the water tank 1;

[0027] By setting up water pump 3, the water in water tank 1 is transferred to spray mechanism 6 to simulate the impact of rainwater on rubber asphalt. The water flow rate can be adjusted by flow meter 5. The model of water pump 3 is set to KDLP1200.

[0028] Among them, a spring 19 is fixedly installed on the inner wall of the baffle 16, and the end of the spring 19 away from the baffle 16 is fixedly connected to one side of the slide plate 18.

[0029] By setting spring 19, when spring 19 is not under pressure, it can control the slide plate 18 and the limit rod 20 to move into the placement mechanism 15 by its own elastic force.

[0030] Among them, the surface of the slide plate 18 is slidably sleeved in the baffle 16, and the side of the slide plate 18 away from the spring 19 is fixedly installed with a limit rod 20, and a limit hole is opened in the placement mechanism 15.

[0031] One end of the connecting rod is fixedly connected to a fluorescent ultraviolet lamp 8, and the two ends of the fluorescent ultraviolet lamp 8 are rotatably sleeved inside the body 25 of the ultraviolet aging test chamber.

[0032] By setting up fluorescent ultraviolet lamp 8, the short-wave ultraviolet part of the sun can be simulated to test whether rubber asphalt is aging.

[0033] Among them, a door panel 22 is rotatably installed on the right side of the UV aging test chamber body 25, and a drain hole 23 is opened on the right side of the UV aging test chamber body 25.

[0034] The front of the UV aging test chamber body 25 is fixedly installed with a second support plate 13, and the upper end of the second support plate 13 is fixedly installed with a servo motor 14. The output end of the servo motor 14 passes through the inner wall of the UV aging test chamber body 25 and is fixedly connected to the front of the placement mechanism 15.

[0035] By setting a servo motor 14, the rotation of the placement mechanism 15 can be controlled when the servo motor 14 is running.

[0036] The working principle of the above embodiments is as follows:

[0037] When in use, firstly, the staff flips the door panel 22 outward and places the rubber asphalt to be tested into the placement mechanism 15;

[0038] After completion, the control baffle 16 slides downward in the placement mechanism 15. When the surface of the baffle 16 is completely slid into the placement mechanism 15, the pressure on the spring 19 is released, so that the spring 19 uses its own elastic force to control the slide plate 18 and the limiting rod 20 to move into the placement mechanism 15, and the limiting rod 20 is inserted into the placement mechanism 15, thus completing the stable installation between the baffle 16 and the placement mechanism 15.

[0039] When different parts of the rubber asphalt need to come into contact with the hollow surface in the placement mechanism 15, the controller 24 is used. The controller 24 is composed of multiple key components, including a program counter, an instruction register, an instruction decoder, a timing generator, and an operation controller 24.

[0040] These components work together to form a "decision-making body" that issues commands, so that commands can be issued to other devices. When the servo motor 14 is driven to work through a pre-set program, the servo motor 14 can drive the entire placement mechanism 15 to rotate.

[0041] When the water pump 3 is driven, the water pump 3 can transfer the water in the water tank 1 to the water supply pipe 4. The flow rate of the water supply can be controlled by the flow meter 5. When the water flows into the spray mechanism 6, the spray mechanism 6 is composed of conventional devices such as water pump, water pipe, and water supply tank. These are well known technologies to those skilled in the art, so they are not described in detail in this embodiment. This is to simulate the impact of rainwater on rubber asphalt.

[0042] The UV aging test chamber body 25 is equipped with a lamp device 7. The lamp device 7 can be used to generate light and heat, and can be selected by the user according to the actual situation. The built-in temperature control can achieve blackboard temperature adjustment from 40°C to 90°C, and integrates condensation circulation to simulate dew erosion.

[0043] Fluorescent ultraviolet lamps, such as UVA-340 and UVB-313 lamps, are used to simulate the short-wave ultraviolet portion of the sun, covering the UV-A 315-400nm and UV-B 280-315nm bands.

[0044] In order to ensure that the UV aging test chamber body 25 is more comprehensive during irradiation, the telescopic cylinder 21 can be extended and retracted to pull the movable plate 10 through the first movable plate 11.

[0045] Meanwhile, the fluorescent ultraviolet lamp 8 is rotated by the connecting rod at one end of the movable plate 10, so that the fluorescent ultraviolet lamp 8 rotates inside the ultraviolet aging test chamber body 25, realizing multi-angle irradiation of rubber asphalt by the fluorescent ultraviolet lamp 8 and improving flexibility.

[0046] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
