The invention relates to a road structure nondestructive continuous detection device based on ultrasonic waves. The device comprises a traction mechanism and a detection mechanism. The traction mechanism comprises a traction rack, a fork head, and a rolling shaft and a rolling wheel fixedly connected with the traction rack. The detection mechanism comprises a traction rod, a driven shaft, a detection wheel, and a water tank and a control mechanism arranged on the traction rack. The control mechanism comprises an ultrasonic transducer, a rotary encoder, and a controller. The rotary encoder form signal connection with the ultrasonic transducer through the controller. The ultrasonic transducer provided by the invention can transmit and receive ultrasonic wave signals under the effect of a coupling agent, and can convert the signals into electrical signals; and the electrical signals can be inputted into a host computer. The design is reasonable, and structure is simple. The detection is vehicle-loaded detection, such that the interference to traffic is low. The device has the advantages of convenient application, high detection speed, high detection efficiency, and accurate detection result. The device is used in road structure nondestructive continuous detection.
Description
technical field [0001] The invention relates to the field of traffic road detection, in particular to an ultrasonic-based non-destructive continuous detection device for road structures. Background technique [0002] Early detection of road recessive diseases is the premise of preventive maintenance technology in road maintenance technology. With the continuous development and progress of microelectronics technology, ultrasonic detection technology is more and more widely used in industrial production. However, due to its own characteristics, ultrasonic technology Due to the limitations of the industry and the current application of ultrasonic technology in road detection, point-by-point detection is the main method. Point-by-point detection has disadvantages such as long time-consuming single point, high cost, low sampling efficiency, and many safety hazards, which seriously hinder the promotion and application of ultrasonic non-destructive testing technology in road site i...
