为了解决SONOTRONTM超声波站检测效率低、误判率高等问题,通过开发新型探头材料,研制方形探头等实现了探头国产化,并首创了在线随动探伤方法.结果表明:采用国产化探头,超声波站设备故障时间降低83.3％;探头寿命提高6.5倍,探头价格降低一半,在线更换调整时间缩短2/3;检测出钢轨缺陷的重现率不小于99.55％,且探伤起落架可适用于多种规格的重轨.

To solve the problem of low detecting efficiency,high misjudgment ratio in SONOTRONTM ultrasonic inspection station,new probe materials and square probe were developed and home-made successfully.In addition,the method of online follow-up detecting was initiated,Results show that by using the domestic probe,failure time of ultrasonic inspection devices reduced by 83.3 ％,probe service life extended by 6.5 times,probe price lowered by half,online replacement and adjustment time was shortened by 2/3,detecting recurrence rate of heavy rail defects was no less than 99.55 ％,and the detecting landing gear can be applied to various specifications of heavy rail.
