Embodiment Construction

[0035] Attached to the following Figure 1-4 This application will be described in further detail.

[0036] The embodiment of the present application discloses a road smoothness detection vehicle. refer to figure 1 , the road smoothness detection vehicle includes a vehicle body 1, a detection device 2 arranged on the vehicle body 1 for detecting the road smoothness, and a cleaning device 3 arranged on the vehicle body 1 for cleaning impurities on the road. The device 3 is arranged at one end near the forward direction of the vehicle body 1. The cleaning device 3 can clean the impurities on the road. After the cleaning is completed, the detection device 2 will detect the smoothness of the cleaned road.

[0037] refer to figure 1 and figure 2 The vehicle body 1 includes a horizontally arranged vehicle panel 11 , a traveling wheel 12 rotatably connected to the lower side of the vehicle panel 11 , and a handle 13 fixed on the vehicle panel 11 for pushing the vehicle panel 11 ...

Abstract

The invention relates to the technical field of road detection, in particular to a road flatness detection vehicle which comprises a vehicle body and a detection device arranged on the vehicle body and used for detecting road flatness. The detection device comprises a plurality of detection rods sequentially arranged in the width direction of the road, a plurality of piezoelectric sensors arranged on the vehicle body and located at the upper end of each detection rod and a processing module connected with the piezoelectric sensors at the same time, the detection rods are slidably connected with the vehicle body, and when the lower ends of the detection rods make contact with the surface of the road, the piezoelectric sensors are connected with the processing module. The upper ends of the detection rods abut against the piezoelectric sensors, the piezoelectric sensors are used for detecting the vertical movement distance of each detection rod so as to obtain protruding values of all positions of a road, and the processing module is used for obtaining the flatness index of the road after obtaining data detected by the piezoelectric sensors. The method has the advantages that the detection speed can be increased, interference on traffic during detection is reduced, the operation convenience is optimized, and the detection efficiency is improved.

Description

technical field [0001] The present application relates to the field of road detection technology, and in particular, to a road smoothness detection vehicle. Background technique [0002] The surface flatness 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. [0003] At present, the main methods for measuring road surface smoothness are: fixed-length ruler method, that is, a ruler with a specified length is used to place it on the road surface. Half of the currently used is a three-meter ruler. W...
