Injury detector for motorcycle wheel to ground of portable electromagnetic ultrasonic surface wave

The utility model discloses a portable electromagnetism hypersonic surface wave flaw detector of the engine wheel to the tread. The hypersonic frequency signal generated by the hypersonic frequency signal generating device in the main machine is amplified by a logic control unit power amplifier and generates a hypersonic surface wave on or near the surface of the wheel through a electromagnetism hypersonic switching device. The hypersonic surface wave spreads along the wheel to the surface and the returned hypersonic surface returning wave is received by an electromagnetism hypersonic receiver, amplified by a programming amplifying unit in the main machine, converted into a digital signal by a analogue/digital converter and sent to be stored in the memory device through the logic control unit directly or through the logic control unit after the process of the digital signal processing unit. The flaw detector can automatically realize the one-shot comprehensive covering scan of the periphery of the wheel thread without the cleaning of the surface of the wheel under inspection and the couplant in the inspection and accomplish the thread flaw detecting task with wheel undetached, simplicity, high speed and efficiency. The portable electromagnetism hypersonic surface wave flaw detector is convenient for carrying and applicable in particular to the base stations and sections.
