摘要:
钢轨探伤车作为当前国内铁路钢轨探伤的主要手段,承担着绝大部分线路钢轨母材的检测任务。针对其在山区铁路轨头核伤检出率偏低的问题,以南昆铁路百威段为研究对象,通过收集伤损轨基本信息,对比探伤车与探伤仪在轨头核伤检测原理上的差异,进而分析山区铁路线路特性对探伤车检测效果的影响。在此基础上,提出调整XF70°入射角度和位置、采用降速检测等措施以保证对中良好,运用高灵敏度探伤和精细化对比分析数据回放等方法优化探伤车对山区铁路轨头核伤的检出能力。此类措施在南昆铁路百威段的实际检测中得到了有效验证,可为类似山区铁路的钢轨探测作业提供参考。
Abstract:
As the primary method for rail flaw detection in China's railway system, rail flaw detection vehicles undertake the majority of inspection tasks for rail base metal along most lines. Aiming at the issue of their low detection rate for rail head nuclear flaws on mountainous railways, this study took the Baise-Weishe Section of Nanning-Kunming Railway as the case study. By collecting basic information on flawed rails and comparing the differences in detection principles between rail flaw detection vehicles and handheld flaw detectors for rail head nuclear flaws, the impact of mountainous railway line characteristics on the detection effectiveness of the rail flaw detection vehicles was analyzed. On this basis, measures such as adjusting the incidence angle and position of the XF70°channel, adopting reduced-speed detection to ensure proper alignment, applying high-sensitivity flaw detection, and conducting refined comparative analysis during data playback were proposed to optimize the detection capability of rail flaw detection vehicles for rail head nuclear flaws on mountainous railways. These measures have been effectively verified in actual inspections on the Baise-Weishe Section of the Nanning-Kunming Railway and can provide references for rail flaw detection operations on similar mountainous railways.
