Embodiment Construction
[0035] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0036] refer to Figure 1 to Figure 14 , the shading device of the vehicle-mounted road surface crack detection system based on the eccentric linkage mechanism includes a shading plate 1, a shading plate fixing part 2, a base 3, a connecting rod 4, a threaded end cover 5, a motor 6, a bevel gear 7, an eccentric wheel 8, and a shaft The fixing part 10, the bevel gear shaft 11 and the connecting rod connecting shaft 12.
[0037]The base 3 is a rectangular part made of a rectangular steel plate, with a stepped hole and a set of threaded holes processed on the surface. The base 3 is placed on a level ground, and the thrust ball bearing is pressed into the stepped hole of the base 3 and has an interference fit with the base 3. The outer end face of the thrust ball bearing is in contact with the end face of the stepped hole of the base 3. The bevel gear shaft 11 is a steppe...

The invention discloses a shading device for a vehicle-mounted pavement crack detection system based on an eccentric connecting rod mechanism, and aims to solve the problem of shading of the vehicle-mounted pavement crack detection system based on the eccentric connecting rod mechanism. The shading device for the vehicle-mounted pavement crack detection system based on the eccentric connecting rodmechanism mainly consists of a shading plate (1), a shading plate fixing part (2), a base (3), a connecting rod (4), a threaded end cover (5), a motor (6), bevel gears (7), an eccentric wheel (8), ashaft fixing part (10), a bevel gear shaft (11) and a connecting rod connecting shaft (12), wherein a circular hole of a boss of the eccentric wheel (8) is mounted at the end of the bevel gear shaft (11) in a sleeving manner; and a bolt penetrates through the threaded hole on the side surface of the boss of the eccentric wheel (8) and is in threaded and fixed connection with the threaded hole at the end of the bevel gear shaft (11). The invention provides the shading device for the vehicle-mounted pavement crack detection system based on the eccentric connecting rod mechanism, and the shadingdevice is simple in structure and reliable in 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 an eccentric link mechanism. Background technique [0002] With the rapid increase of traffic volume, the speed of road damage is increasing day by day. Pavement cracks, as a very common road surface damage, pose a very serious threat to the use of roads and the safety of driving. Therefore, the detection of pavement cracks is extremely important. When the vehicle-mounted pavement crack detection system detects cracks, light has an important impact on the collection effect of road surface images. Therefore, the use of automatic shading system to detect pavement cracks has important application value. The eccentric link mechanism has the advantages of simple structure and convenient design. The invention adopts the eccentric link mech...
