Flatness detection device for road detection

Abstract

The invention discloses a flatness detection device for road detection, and the device comprises a vehicle plate, the two sides of the lower end of the vehicle plate are fixedly provided with mounting racks, the middle part of the lower end of each mounting rack is movably provided with a roller, the middle part of the lower end of the vehicle plate is movably provided with a fixed block through a device, and the surface of the fixed block is provided with a detection mechanism. The detection mechanism comprises a connecting rod, a connecting block, a clamping groove and a ball, the connecting rod is movably arranged on the outer side surface of the fixing block through a rotating shaft, the connecting block is fixedly arranged at the end, away from the fixing block, of the connecting rod, the clamping groove is formed in the outer side surface of the lower end of the connecting block, and the ball is movably clamped in the clamping groove. The road surface flatness detection device is good in use effect, can conveniently detect the flatness of a road surface, can conveniently drive the balls to detect along an S route during detection, and is larger in detection range of spot check and easier to judge the tidiness of the road surface compared with traditional straight line detection.

Description

technical field [0001] The invention relates to the technical field of road detection, in particular to a flatness detection device for road detection. Background technique [0002] The road surface smoothness refers to the deviation value of the amount of unevenness in the longitudinal direction of the road surface. Pavement smoothness is an important index in pavement evaluation and pavement construction acceptance, which mainly reflects the smoothness of the profile curve of the pavement longitudinal section. When the profile curve of the longitudinal section of the road surface is relatively smooth, it means that the road surface is relatively smooth, or the smoothness is relatively good; otherwise, the smoothness is relatively poor. A good road requires a good level of road surface. The smooth road is not only related to the service life of the road, but also related to driving safety. [0003] At present, when testing the road surface smoothness, the commonly used m...

Problems solved by technology

[0004] 1. The current three-meter ruler detection method needs to manually attach the three-meter ruler to the upper end of the ground on the road surface, and then insert a feeler gauge with height markings into the gap to detect and judge the smoothness of the road surface, which is labor-intensive. , low work efficiency;

[0005] 2. The current three-meter ruler detection method is not continuous, and requires manual continuous sampling inspection on the road surface, which cannot continuously detect the road surface, and the detection range is limited
