AI Technical Summary
Existing asphalt pavement crack detection equipment cannot adjust the ultrasonic emission angle when detecting bending cracks, resulting in inaccurate data and the inability to emit signals vertically, which affects the detection accuracy.
An asphalt pavement crack detection device was designed. By rotating the handle and connecting structure, the ultrasonic detection head is moved into the crack. The telescopic rod and spring make it fit against the crack wall. Combined with the motor rotation, the ultrasonic detection head is adjusted to a vertical position. With the help of a camera, accurate data collection is achieved.
This improved the accuracy and efficiency of asphalt pavement crack detection, ensuring the accuracy and completeness of the detection data.
