Abstract

The invention discloses a railway axle phased array ultrasonic flaw detection self-adaptive scanning device. Air compression force is adopted for driving an ultrasonic probe clamp, the gas flow rate and pressure can be regulated, the pressure is positioned in a floating manner, the clamp and the probe can be prevented from being damaged by excessive pressure, and the safety of detection equipment can be further protected; during the positioning process of the probe, according to the detected axle diameter, the single-axle rotational angle of the probe can be regulated in a self-adaptive manner for meeting the flaw detection requirements of railroad car axles with different diameters; and during the flaw detection process, the probe can move along a telescopic guide pole, the joint pressure between the probe and the surface of the axle can be regulated by extension and contraction of a pressure spring, the friction force between the surfaces of the probe and the axle can be reduced along with the rotation of rolling wheels, and the stability in coupling of the probe can be further ensured. The railway axle phased array ultrasonic flaw detection self-adaptive scanning device disclosed by the invention has the advantages of convenience in operation and strong applicability, and can ensure the safety and stability in probe positioning and improve the ultrasonic axle flaw detection efficiency.

Description

technical field [0001] The invention relates to the field of axle detection, in particular to an adaptive scanning device for railway axle phased array ultrasonic flaw detection. Background technique [0002] The scanning device of the axle ultrasonic detection probe is an important device for positioning and coupling of the probe in the ultrasonic flaw detection of the train axle. . The scanning device of the whole set of probes is the core component of the whole set of axle ultrasonic testing system. At present, in the traditional ultrasonic flaw detection of train axles, the flaw detection of key parts such as the axle diameter, axle body, wheel seat, etc., often uses ultrasonic probes with fixed fixtures. For axles with different diameters and different parts of the same axle, different The ultrasonic probe fixture adapts to the change of the axle diameter, which brings inconvenience to the axle ultrasonic flaw detection and low detection efficiency; in addition, the t...
