Description

Technical Field

[0001] This utility model relates to the field of road material performance testing technology, specifically a reflective asphalt reflectivity performance testing frame. Background Technology

[0002] With the continuous development of urban transportation, road safety is receiving increasing attention. Reflective asphalt, as a new type of road material, is widely used because it can reflect light at night or in low-light conditions, improving road visibility and thus reducing the incidence of traffic accidents.

[0003] Currently, the testing methods and equipment for the reflective properties of reflective asphalt are limited and cannot be automated in batches. Most tests rely on visual observation of the reflective effect of the asphalt under different lighting conditions, comparing it with standard samples to provide a qualitative evaluation. This method is highly subjective, heavily influenced by the observer's experience, and cannot provide quantitative results. Existing testing equipment often suffers from complex operation and inaccurate results. Some equipment requires specialized technicians for operation and maintenance, increasing the cost of use. Therefore, a reflective asphalt reflective performance testing frame is needed to address these issues. Utility Model Content

[0026] A reflective asphalt reflectivity performance test frame includes a main body 1, and a rotation adjustment component 2 and a test component 3 are fixedly connected to the top of the main body 1.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the rotation adjustment assembly 2 includes a protective box 201, an inner base plate 202 fixedly connected inside the protective box 201, a motor 203 mounted on the top of the inner base plate 202, a rotating wheel 204 fixedly connected to the output end of the motor 203, a transmission wheel 205 meshing with the side of the rotating wheel 204, a rotating rod 206 fixedly connected inside the transmission wheel 205, and a reflective asphalt sample stage 207 fixedly connected to the top of the rotating rod 206. The test assembly 3 includes a top frame 301, a mounting base 303 fixedly connected to the top of the top frame 301, a connecting rod 304 fixedly connected to the side of the mounting base 303, and a connecting rod 304 fixedly connected to the side of the connecting rod 304. A connecting block 305 is fixedly connected, and a light intensity sensor 306 and a data acquisition card 307 are installed on the side of the connecting block 305. The motor 203 drives the rotating wheel 204 and the transmission wheel 205 to mesh and rotate, which in turn causes the rotating rod 206 to rotate the reflective asphalt sample stage 207. With the help of multiple sample slots 208 on the reflective asphalt sample stage 207, different types of reflective asphalt samples can be placed. By rotating the reflective asphalt sample stage 207, samples can be easily changed for testing, thereby enabling rapid and accurate testing of the reflective performance of reflective asphalt, improving testing efficiency and the reliability of test results.

[0028] The reflective asphalt sample stage 207 has a sample slot 208 inside, and several sample slots 208 are provided. A bearing seat 209 is fixedly connected to the top of the inner bottom plate 202. A rotating rod 206 extends into the interior of the bearing seat 209. An LED light source 302 is fixedly connected to the side of the top frame 301. Two LED light sources 302 are provided. A light intensity sensor 306 is a high-precision photodiode sensor. A support plate 308 is fixedly connected to the bottom of the top frame 301. Two support plates 308 are provided. The light intensity sensor 306, which is a high-precision photodiode sensor, can accurately detect the light intensity reflected by the reflective asphalt and convert the light intensity signal into an electrical signal output. The data acquisition card 307 is used to collect the electrical signal output by the light intensity sensor 306 and convert it into a digital signal to be transmitted to the controller 104. The controller 104 processes and analyzes the collected light intensity data through testing software to obtain the reflective performance index of the reflective asphalt.

[0029] In this embodiment, as Figure 1 and Figure 4As shown, the main body 1 includes a base frame 101. A controller 104 is fixedly connected to the top of the base frame 101.

The reinforcing ribs 103 can effectively prevent the base frame 101 from buckling and becoming unstable when subjected to force. They can increase the rigidity of the structure and keep it stable when subjected to external forces, reducing vibration and deformation. The reinforcing ribs 103 can increase the local material thickness or change the shape of the structure, thereby dispersing and transmitting the force, thus improving the overall strength of the base frame 101.

[0030] The working process of this utility model is as follows: When using the reflective asphalt reflectivity performance testing frame designed in this scheme, different test samples are placed in the sample slot 208, and illuminated by an LED light source 302. During testing, the motor 203 drives the rotating wheel 204 and transmission wheel 205 to mesh and rotate, which in turn causes the rotating rod 206 to rotate the reflective asphalt sample stage 207. Rotating the reflective asphalt sample stage 207 allows for easy sample replacement for testing. The light intensity sensor 306 uses a high-precision photodiode sensor, which can accurately detect the light intensity reflected by the reflective asphalt and convert the light intensity signal into an electrical signal output. The data acquisition card 307 is used to collect the electrical signal output by the light intensity sensor 306 and convert it into a digital signal for transmission to the controller 104. The controller 104 processes and analyzes the collected light intensity data using testing software to derive the reflective performance indicators of the reflective asphalt, thus completing the test of the reflective asphalt sample.
