To provide a rail irregularities measuring method which can manage irregularities of a pair of left and right rail, keeping a synchronous correspondence between the irregularities measuring position and a distance measuring position along the rail.SOLUTION: A rail irregularities measuring method by which positions and shapes of the irregularities generated on top faces of a pair of left and right rails in a prescribed section are measured is provided. The method is characteristic of comprising a step to arrange each of two measuring units on each of a pair of left and right rails, a step to couple the unit each other, a step to move the unit along the rail by each wheel included in the unit and measure a distance of the movement, a step to measure shapes of the top face irregularities of the pair of left and right rails through measuring heights of the top face under the measuring units, a step to detect a position marker at a prescribed position in a prescribed section using a reference position detecting means and a step to make the irregularities measuring position coincide with the measuring position of the movement distance along the pair of left and right rails.SELECTED DRAWING: Figure 1
【課題】 左右一対のレールの凹凸について、レールに沿った位置を同期させながら対応付けて管理可能なレール凹凸測定方法の提供。【解決手段】 所定区間内に設置された左右一対のレールの頭部に生じた凹凸の位置及び形状を測定するレール凹凸測定方法である。左右一対のレールのそれぞれの上に配置させて連結させた2台の計測ユニットをそれぞれに含まれる車輪によってレールに沿った移動量を計測しながら移動させるとともに、計測ユニットの下方のレールの頭部の高さ位置を計測して左右一対のレールの凹凸の形状を測定し、更に、所定区間内の所定位置において基準位置検知手段によって位置マーカを検知させ、計測された凹凸の位置と左右一対のレールに沿った位置とを同期させることを特徴とする。【選択図】図1
