Abstract

The invention discloses a shading device based on drum friction and used for a vehicle-mounted road crack detection system and aims to solve the problem about drum friction based shading of the vehicle-mounted road crack detection system. The shading device based on drum friction and used for the vehicle-mounted road crack detection system mainly comprises fastening bolts (1), sliders (2), boxes (3), a shading plate (4), a lower drum (5), a belt pulley (6), a motor (7), a sand adhering roller (8), a lower roller (9), return springs (10) and a base (11), wherein the belt pulley (6) is connectedwith three annular belt grooves in one end of the sand adhering roller (8) through a standard belt, the shading plate (4) is placed between the sand adhering roller (8) and the lower drum (5), and the thickness of the shading plate (4) is 0.04 mm larger than the gap between the sand adhering roller (8) and the lower drum (5). The shading device based on drum friction and used for the vehicle-mounted road crack detection system is simple in structure and reliable in performance.

Description

technical field [0001] The invention relates to an auxiliary device of a detection device in the field of traffic detection, more particularly, it is a shading device for a vehicle-mounted road surface crack detection system based on a friction roller. Background technique [0002] The quality of the road surface is one of the important factors influencing the safe driving of vehicles. Pavement cracks are a very common road surface damage. Therefore, the detection of pavement cracks is of great significance for timely maintenance of roads and safe driving of vehicles. 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 shield the vehicle pavement crack detection system under different lighting conditions through a shading device. Therefore, it is very important to design a shading device for vehicle-mounted road surface crack detection ...
