Stainless steel tube ultrasonic thickness measuring device with novel probe

Abstract

The invention discloses a stainless steel tube ultrasonic thickness measuring device with a novel probe, which belongs to the technical field of ultrasonic thickness measurement. The stainless steel tube ultrasonic thickness measuring device with a novel probe comprises a host, a probe body and wires, wherein the host and the probe body are electrically connected through a wire; the outer end of the probe body is slidably connected with a limiting sleeve and a U-shaped disc.The device is stably adsorbed on the surface of a pipe through the vacuum adsorption plate; meanwhile, a pair of elasticreels and a cloth belt are automatically adjusted under the action of elastic force,the perpendicularity between the probe body and the outer wall of the pipe and the stability of the position of theprobe body are automatically kept, the probe body can accurately position and measure the pipe, and a sufficient coupling agent is continuously provided for the gap between the probe body and the pipethrough the liquid storage device, so that the probe body and the pipe can keep a good seamless coupling state under the condition of online contact, and the measurement accuracy is further ensured.

Description

technical field [0001] The invention relates to the technical field of ultrasonic thickness measurement, and more specifically relates to an ultrasonic thickness measurement device for a stainless steel tube with a novel probe. Background technique [0002] Ultrasonic thickness measurement technology is based on the principle of ultrasonic pulse reflection to measure thickness. When the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the interface of the material, the pulse is reflected back to the probe. The thickness of the material can be measured, and all kinds of materials that can make the ultrasonic wave propagate inside it at a constant speed can be measured by this principle. [0003] When measuring the thickness of an object by ultrasonic waves, the probe needs to be perpendicular to the surface of the object to be measured. However, when testing pipes, since the pipe wall is not flat, the surface of the commonly used prob...

AI Technical Summary

Problems solved by technology

[0003] When measuring the thickness of an object by ultrasonic waves, the probe needs to be perpendicular to the surface of the object to be measured. However, when testing pipes, since the pipe wall is not flat, the surface of the commonly used probe is flat, and the contact with the pipe wall is point contact or line contact. The position of the ultrasonic thickness measuring probe is easy to move during detection, resulting in large errors in the measurement results
