Description

Technical Field

[0001] The utility model relates to the field of road detection, in particular to a portable annular crack detector for road detection. Background Art

[0002] At present, the road surfaces such as urban roads and highways are mainly paved with asphalt. However, due to the effect of vehicle load and the influence of natural factors, cracks will appear on the asphalt road surface. If these cracks are not repaired in time, it will cause potholes on the road surface, causing more serious damage to the asphalt road surface and affecting driving safety. In order to solve this problem, annular crack detectors came into being. This equipment can detect cracks on the road and evaluate the service life and usage of the road based on the detection results. Usually, the annular crack detector is installed under the cart for work.

[0003] However, in the prior art, the detection equipment lacks an effective cleaning structure, which causes one side of the detection head to be often covered with dust, resulting in inaccurate detection results and affecting the assessment of road conditions. Utility Model Content
