AI Technical Summary
Existing road surface smoothness testing devices can only detect the smoothness of one line on the road surface and cannot effectively assess the flatness of the entire road surface.
A road surface smoothness detection device was designed, which adopts a combination of transmission components and detection components. It realizes the detection of the overall smoothness of the road surface through an electric telescopic rod, a motor-driven bidirectional lead screw and a laser displacement sensor.
It improves the efficiency and accuracy of road surface smoothness detection, and can cover the entire road surface for detection, thus achieving an effective assessment of the overall flatness of the road surface.
