Embodiment Construction
[0010] The method of eliminating the cause of misjudgment of the straightness detection of the online welded rail joints adopts the following steps: a. Check the accuracy of the electronic straight ruler to pass the inspection; In the free state of the construction site, use the electronic straightedge to export the waveform diagram I; c. Select several sections of the laid line to avoid the joint rail parent material, and use the electronic straightedge to export the rail waveform II in the free state of the construction site ; D, take the average value of waveform diagram I and waveform diagram II to form the waveform diagram III of the free state rail of qualified welds; e, select several groups of rail factory welding joints fixed on the line and some sections of rail base metal respectively, and measure its waveform Figure and take the mean value to form the waveform diagram IV of the fixed state rail; f, take the waveform diagram III and IV as the horizontal axis with the...
