Description

Roughness detection device for municipal road Technical Field The utility model relates to the technical field of road flatness detection, in particular to a flatness detection device for municipal roads. Background The road surface flatness refers to a deviation value of the longitudinal concave-convex amount of the road surface, is an important index in road surface evaluation and road surface construction inspection, and mainly reflects the flatness of a road surface longitudinal section profile curve. Through retrieval, chinese patent publication No. CN217499872U discloses a pavement evenness detecting device for municipal roads, the utility model drives a first cross rod to move by rotating a threaded rod, the moving first cross rod drives a guide block to move in a guide groove, and the guide block guides the first cross rod, so that the distance between the two first cross rods can be adjusted according to actual requirements. The device adjusts the distance between two horizontal poles through the threaded rod, but two horizontal poles are controlled by two sets of independent threaded rods respectively, when need to adjust the distance of two laser sensors in the use, need rotate two sets of threaded rods in proper order and adjust the position of two horizontal poles, not only very troublesome, and regulation speed is slower, influences road detection efficiency. Disclosure of utility model In order to make up for the defects, the utility model provides a flatness detection device for municipal roads, and aims to solve the problem that the adjustment of the distance between laser sensors is too complicated in the prior art.
