The invention provides a highway pavement detection vehicle. A comprehensive detection part comprises a hydraulic rod, a blind pipe, a pressure sensor, a pressure-bearing spring, a sliding shaft and arigid roller, the hydraulic rod is fixedly installed on a carriage, the output end of the hydraulic rod is fixedly connected with the blind pipe, a blind hole is formed in the blind pipe, and a second sensor is used for detecting the distance value between the second sensor and the pressure sensor; the pressure sensor is arranged in a protective sleeve; and the protective sleeve is coaxially fixed on the end surface of the sliding shaft and coaxially arranged in the pressure-bearing spring. A flatness detection part comprises a transverse gradienter and a pair of longitudinal gradienters fixedly connected with connecting rods respectively, and one ends of the two longitudinal gradienters are correspondingly and fixedly connected to the two ends of the transverse gradienter respectively, so that the flatness detection part is in an n shape as a whole. The highway pavement detection vehicle is ingenious in structure, diversified in design function, flexible and reliable to use, simple in manual detection operation, time-saving and labor-saving.

    本发明提供了一种公路路面检测车,其综合检测部件包括液压杆、盲管、压力传感器、承压弹簧、滑动轴以及刚性滚轮,液压杆固定安装在车厢上,液压杆的输出端与所述盲管固接,盲管的内部开设有一个盲孔,第二传感器用于检测其与所述压力传感器之间的间距值;所述压力传感器内置于保护套管内,该保护套管同轴地固定在滑动轴的端面上并同轴地设置在所述承压弹簧内部;平面度检测部件包括一根横向水平仪和各与一根连杆固接的一对纵向水平仪,两纵向水平仪的其中一端分别对应地固接在横向水平仪的两端,以使得平面度检测部件整体呈“П”型。本发明结构巧妙,设计功能多元化,使用灵活可靠,人工检测操作简单,省时省力。
