Technical Field

[0001] The utility model relates to the technical field of crack detection equipment, in particular to an intelligent detection device for cracks on an asphalt pavement. Background Art

[0002] Most of the roads in the city are paved with asphalt to form asphalt pavement. Due to the effect of vehicle load and the influence of natural factors, pit-shaped cracks will appear on the asphalt pavement. Some cracks are shallow and will not have too much impact on the asphalt pavement, but some cracks are deep. If they are not repaired in time, the traffic on the bridge will cause deeper damage to the asphalt pavement and affect driving safety. Therefore, crack monitors are often used to inspect and repair road cracks.

[0003] When using existing crack detectors, the measuring head is mostly connected to the body through a plug, and then the handheld measuring head is fitted to the road surface. At the same time, the measuring head emits sound waves and measures the depth of the crack through the rebound of the sound waves.

However, due to the lack of a structure to reinforce the plug at the connection between the plug and the body, the person may accidentally drag the handheld measuring head when moving it, causing the connection between the plug and the body to loosen and separate, affecting the normal measurement of the body.
