Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0027] refer to Figure 1 to Figure 8 , the shading device of the vehicle-mounted road surface crack detection system based on the eccentric rocker mechanism includes a bottom plate 1, an eccentric wheel 2, a slide rocker 3, a connecting rod 4, a centering rocker 5, a guide groove 6, a Y-shaped push rod 7 and a shading device. plate 8.

[0028] Bottom plate 1 is an L-shaped part made of two rectangular steel plates welded vertically. Two threaded holes and a groove are processed on the vertical steel plate. Bottom plate 1 is fixed on the front end of the car by bolts. Slide rocker 3 is made of steel plates. A long rod-shaped part, with a slender transparent chute in the middle, a circular through hole processed at both ends of the slide rocker 3, a long groove processed at one end of the slide rocker 3, and a bolt passing through the upper end of the slide rocker 3 T...

Abstract

The invention discloses a shading device based on an eccentric rocker mechanism and used for a vehicle-mounted road crack detection system and aims to solve the problem about eccentric rocker mechanism based shading of the vehicle-mounted road crack detection system. The shading device based on the eccentric rocker mechanism and used for the vehicle-mounted road crack detection system mainly comprises a bottom plate (1), an eccentric wheel (2), a slide rocker (3), a connecting rod (4), a centering rocker (5), a guide groove (6), a Y-shaped push rod (7) and a shading plate (8), wherein two sidesurfaces in the guide groove (6) are in surface contact slide fit with two side surfaces of the Y-shaped push rod (7), the distance between the inner top surface of the guide groove (6) and the bottom surface of the Y-shaped push rod (7) is not smaller than 1 / 2 of the length of the centering rocker (5), and one end of the shading plate (8) is welded and fixedly connected with the Y-shaped push rod (7). The shading device based on the eccentric rocker mechanism 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 for detection equipment in the field of traffic detection, more specifically, it is a shading device for a vehicle-mounted road surface crack detection system based on an eccentric rocker mechanism. Background technique [0002] Pavement crack is a very common highway pavement damage, which has an important impact on driving safety. The detection of pavement cracks is of great significance to prolonging the service life of roads and ensuring driving safety. In the process of collecting pavement crack information, the external light has an important influence on the collection results. Reasonable control of external light should be carried out during the detection process. Therefore, it is very important to design a shading device for a vehicle-mounted pavement crack detection system that has a shading function for external light. Contents of the invention [0003] Aiming at the problem that external lig...
