Abstract

The invention discloses a shading device for a vehicle-mounted road surface crack detection system based on a friction roller, aiming at solving the shading problem of the friction roller-based vehicle-mounted road surface crack detection system. The shading device of the vehicle-mounted road surface crack detection system based on the friction roller is mainly composed of fastening bolts (1), sliders (2), box body (3), shading plate (4), lower roller (5), pulley (6), motor (7), sand sticking roller (8), lower roller (9), return spring (10) and base (11) form. The belt pulley (6) is connected with the three annular belt grooves at one end of the sticky sand roller (8) through a standard belt, the light shield (4) is placed between the sticky sand roller (8) and the lower drum (5), and the light shield The thickness of (4) is greater than the gap 0.04mm between the sticky sand roller (8) and the lower cylinder (5). Provided is a friction roller-based shading device for a vehicle-mounted pavement crack detection system with simple structure and reliable performance.

Description

technical field [0001] The invention relates to an auxiliary device for detection equipment in the field of traffic detection, more specifically, it is a light-shielding device for a vehicle-mounted road surface crack detection system based on a friction roller. Background technique [0002] Road surface quality is one of the important factors affecting the safe driving of automobiles. Pavement cracks are a very common condition of highway pavement damage, so the detection of pavement cracks is of great significance to the timely maintenance of roads and the safe driving of automobiles. In the process of collecting cracks, light has an important influence on the collection results. In order to ensure the accuracy of pavement crack detection, it is necessary to automatically shading the vehicle-mounted pavement crack detection system under different lighting conditions through a shading device. Therefore, it is very important to design a shading device for a vehicle-mounted...
