Abstract

The invention discloses an ultrasonic detection wheel calibration system and method. The system comprises a base, a mounting frame,a detection wheel mounting part, a bearing part, a liquid storage tank, a calibration test block, asheet-shaped wheel film and a detection wheel, wherein the mounting frame is arranged on the base; the detection wheel mounting part is arranged on the mounting frame andis used for fixing the detection wheel; the bearing part is arranged on the base; the relative positions of the detection wheels can be changed in the three directions perpendicular to one another inpairs relative to the bearing part; the liquid storage tank is arranged on the bearing part; the calibration test block is arranged in the liquid storage tank and is used for testing the performanceof the detection wheel; the sheet-shaped wheel film is arranged at the top of the calibration test block, the sheet-shaped wheel film is used for simulating amplitude attenuation generated when ultrasonic waves pass through the wheel film of the detection wheel, and the upper surface of the detection wheel liquid submerges the sheet-shaped wheel film; and the detection wheel is mounted on the detection wheel mounting part. The system can solve the technical problems that according to an existing ultrasonic detection wheel calibration mode, one detection wheel needs to be used for calibrating aplurality of probes of the same type, much time needs to be spent on probe replacement before each calibration, and efficiency is very low.

Description

technical field [0001] The invention relates to the technical field of track engineering machinery, in particular to an ultrasonic probe calibration system and method for ultrasonic detection of railway rails. Background technique [0002] As my country's railway mileage continues to grow, the speed of railway transportation continues to accelerate, and urban rail transit is becoming more and more developed, the requirements for engineering machinery and equipment that ensure the safety of railways and urban rail transit are also getting higher and higher. Rail detection equipment based on the principle of ultrasonic flaw detection has been widely used in railway engineering systems and urban rail transit fields. Rail detection equipment based on the principle of ultrasonic flaw detection must use coupling fluid as a medium to transmit ultrasonic waves to the interior of the rail to detect damage. Wheel-type ultrasonic flaw detection technology has developed rapidly in the ...
