The invention discloses a track gauge widening type turnout track state detection method and device. The method comprises the steps that machine account data and track detection data of a high-speed railway are obtained; determining the turnout arrangement direction according to the mileage of the point rail point slicing position and the mileage of the point rail point slicing position; mileage error correction is carried out on the rail detection data of the widened turnout according to the rail direction irregularity measurement data, the preset point and rail point mileage of the widened turnout and the turnout arrangement direction; and determining the track state of the widened turnout according to a preset track direction widening value of the widened turnout, the track direction irregularity measurement data after error correction, a preset track gauge widening value of the widened turnout, the track gauge irregularity measurement data after error correction and the superelevation measurement data after error correction. According to the method, turnout characteristics are identified based on the rail detection data of the widened turnout, secondary correction is carried out on the rail detection data of the widened turnout, and the efficiency and accuracy of track state detection of the track gauge widened type turnout are improved.
本发明公开了轨距加宽式道岔轨道状态检测方法及装置,方法包括:获取高速铁路台账数据、轨检数据;根据尖轨尖刨切处里程和心轨尖刨切处里程确定道岔布置方向;根据轨向不平顺测量数据、预设的加宽道岔的尖轨尖里程及道岔布置方向对加宽道岔的轨检数据进行里程误差修正;根据预设的加宽道岔的轨向加宽值、误差修正后的轨向不平顺测量数据、预设的加宽道岔的轨距加宽值、误差修正后的轨距不平顺测量数据、误差修正后的超高测量数据,确定加宽道岔的轨道状态。本发明基于加宽道岔的轨检数据识别道岔特征,对加宽道岔的轨检数据进行二次修正,提高了轨距加宽式道岔轨道状态检测的效率及准确性。
