Steel rail probe development test method and test platform

Abstract

The invention relates to a steel rail probe development test method and a test platform, and the method comprises the steps: simulating a detection wheel through an open water tank filled with coupling liquid, enabling the environment of a probe in the open water tank to be equal to the environment of the probe in the detection wheel, and enabling a tester to carry out the development test according to the test requirements; the probes can be rapidly and effectively installed, debugged and replaced in the open type water tank, the cost of the whole testing work is greatly reduced, the probes can be tested, debugged, improved and optimized one by one till the probes completely meet the requirements of the probe wheel, and then the probes are installed in the probe wheel and packaged. The performance test of the internal probe of the detection wheel after all the probes are mounted into the detection wheel is not needed, so that the defective rate of the finished detection wheel is greatly reduced; meanwhile, performance development of the probe is more convenient, once test data of a certain probe do not meet requirements, the probe can be independently improved and optimized, probe reproduction is not needed, and the development cost of the probe is further reduced.

Description

technical field [0001] The invention relates to the technical field of ultrasonic flaw detection, in particular to a development and testing method and a testing platform of a rail probe. Background technique [0002] As the detection component of the rail flaw detection vehicle, the ultrasonic probe is mainly used to detect the specified artificial damage on the rail. The probe wheel for rail ultrasonic flaw detection is equipped with nine single probes, including a 0° straight probe, two 37° oblique probes and six 70° oblique probes, of which the 0° straight probe is set in the middle, and the two 37° probes are located in the middle. The oblique probes are symmetrically arranged on the front and rear sides of the 0° straight probe, and the six 70° oblique probes are respectively arranged on the left front side, right front side, left rear side, right rear side of the 0° straight probe, and in front of the front 37° oblique probe. Lateral and posterior 37° oblique probe t...

Problems solved by technology

[0003] Whether the probe is qualified or not depends on whether the damage can be detected on the rail. At present, conventional probes have to go through "development of probes - improvement of probes - assembly of finished probes - installation of finished probes on the flaw detection vehicle - rail flaw detection" This ultra-long process can only be evaluated by flaw detection testing, which makes the development cycle of the detection wheel relatively long and the development cost high

Since the probe wheel is tested, the bracket of the probe wheel has been installed inside the wheel skin, and the wheel skin has been filled with coupling fluid, it is impossible to judge the status of each probe in the probe wheel with the naked eye, even if a certain probe is detected to be incompatible Test requirements, also need to return to the factory to replace the probe, the time cost is very high
