AI Technical Summary

Technical Problem

During the inspection process of the existing road flatness detection device, the rise or fall of the frame will affect the height of the measurement wheel, resulting in low detection accuracy and unstable gap between the measurement wheel and the ground reference surface.

Method used

A road flatness detection device is designed, using road barrier shielding components and rotational adjustment components. When the frame is inclined, the driving detection component drives the detection component to move in reverse to keep the gap between the measuring wheel and the ground reference surface equal to the rotation adjustment component when the frame is rotating, the detection component controls the detection component to rotate in reverse and at the same angle to keep the measurement wheel always parallel to the plumb line.

Benefits of technology

It effectively reduces the length of the vehicle body, improves the accuracy of the detection of irregular road surfaces of the measurement wheels, and ensures the accuracy of road flatness data calculation.

Abstract

The present invention relates to the technical field of flatness detection devices, and in particular to a road flatness detection device and detection method. Its technical solution includes: a frame and an extension frame slidably mounted on the frame, the frame and the extension frame constitute a vehicle frame, and also includes: a roadblock shielding component mounted on the vehicle frame, when the wheel assembly component contacts the concave and convex surface and drives the vehicle frame to tilt, the roadblock shielding component drives the detection component to move in the opposite direction of the tilting direction, and controls the ground clearance of the detection component to always remain equal. The present invention uses the roadblock shielding component to move the measuring wheel located in the middle of the frame downward when one end of the frame rotates, and the downward movement distance is half of the rising height of the rising end of the frame, which can avoid the influence of the rising or falling end of the frame on the measuring wheel, and thus can effectively improve the accuracy of the measuring wheel when measuring irregular roads, and can effectively improve the accuracy of calculating the road surface flatness data.
