AI Technical Summary
Existing highway guardrail inspection tools require manual adjustment of the measuring ruler during measurement, which is inefficient and prone to errors, and cannot effectively avoid the influence of the steel beam curvature on the inspection results.
The upper part of the measuring ruler is fixed by a support frame, and non-contact measurement is carried out in combination with a laser irradiator. The measuring ruler is kept vertical by the support feet and the universal ball, and the height of the guardrail is determined by laser irradiation.
This reduces manpower input, improves testing accuracy and speed, and avoids the influence of steel beam curvature on test results.

In order to effectively block the vehicle, the national regulations stipulate the maximum height and the center height of the guardrail of the expressway. Therefore, the height of the guardrail needs to be detected during the acceptance or maintenance of the expressway. In order to improve the measuring speed, some detection tools are designed. For example, a road guardrail beam center height testing device is disclosed in Chinese patent No. 202121865655.7, which comprises a vertical ruler, a first level, a sliding part, a fixing part, a horizontal ruler and a second level. The vertical ruler has a scale line and a trapezoidal groove. The horizontal ruler is moved to contact the top end and the bottom end of the guardrail. When this kind of device is actually used, the contact type measurement has certain error due to the arc of the upper and lower ends of the corrugated steel beam.
