Abstract
Description
Technical Field
[0001] This utility model relates to the field of road surface testing technology, specifically a rapid road surface smoothness testing device. Background Technology
[0002] Road surface smoothness testing is an important means of assessing the smoothness and quality of road surfaces. It can measure and analyze the impact of the road surface on vehicles during driving to ensure traffic safety and driving comfort. Road surface smoothness testing mainly includes: manual measurement, laser measurement, smoothness testing instrument testing, three-dimensional scanning technology testing, and dynamic evaluation system testing.
[0003] In the current practice of using lasers to measure road surface smoothness, a long, rectangular laser measurement system is typically installed in front of a moving vehicle. This system requires multiple laser transmitters and receivers to be mounted on a platform. The transmitters and receivers are usually fixed to the platform using bolts, making it difficult to adjust the spacing between adjacent transmitters and hindering accurate road surface smoothness testing. Furthermore, the lack of external protective mechanisms means that small stones flying from the road surface can easily damage the laser transmitters during smoothness testing. Therefore, we propose a rapid road surface smoothness testing device to address these issues. Utility Model Content

The connecting blocks 54 are movably engaged with the side of the first protective side frame 51 closest to the mounting blocks 53, thus securing the second protective side frame 52. Installation: A second fixing bolt 541 is threadedly installed on the side of the first protective side frame 51 near the connecting block 54. The end of the second fixing bolt 541 is threaded onto the corresponding connecting block 54. The second protective side frame 52 is fixed by using the second fixing bolt 541.
