  • Publication number: 20200225192
    Abstract: The present invention discloses a visual ultrasonic nondestructive testing device and method for a deep/long-hole pipe. The device is composed of an ultrasonic measurement module, a mechanical motion module, a control module, and a coupling injection and assistance module. The ultrasonic measurement module includes an ultrasonic pulse transmitter/receiver, and the ultrasonic transmitter/receiver includes a high-speed analog/digital (A/D) converter; the mechanical motion module includes a scanning device, a probe and a holding device thereof, and a magnetic drive device. A scanning device can move in two directions, that is, an X-axis on which a magnetic driving wheel steps and a Y-axis on which a module body tests. During the scanning process, on the X-axis, a stepping motor drives a synchronous wheel-belt transmission, so that the magnetic driving wheel is rotated to achieve the purpose of stepping; on the Y-axis, a stepping motor on the module body drives the probe to reciprocate.
