To provide a rail wavy wear measurement device that can continuously measure irregularity due to a wavy wear caused in a vertex surface of a rail.SOLUTION: As at least two rollers 12 of a plurality of rollers 12 provided in a wavy wear measurement device 100 are configured to contact with a vertex surface of a rail R corresponding to a wavy convex part of a wavy wear, the wavy wear measurement device 100 is configured to be movable on a virtual surface that includes a virtual line connecting portions where the two rollers contact with the rail R, and connects the wavy convex parts of the wavy wear. That is, the wavy wear measurement device 100 can move on the rail R so as to run along a reference surface S with a surface including the virtual line connecting the portions (wavy convex parts of the wavy wear) where the two rollers 12 of the plurality of rollers 12 contact with the rail R as the reference surface S, not relying on irregularity of the wavy wear, and thus, the wavy wear measurement 100 measures a distance to the vertex surface of the rail R from the reference surface S to enable a continuous measurement of the irregularity due to the wavy wear.SELECTED DRAWING: Figure 1
【課題】レールの頭頂面に生じた波状摩耗による凹凸を連続的に測定することができる波状摩耗測定装置を実現する。【解決手段】波状摩耗測定装置100は、複数のローラー12のうち少なくとも2つのローラー12が波状摩耗の波形の凸部に相当するレールRの頭頂面に接触するので、波状摩耗測定装置100はその2つのローラー12がレールRと接触した箇所を結ぶ仮想線を含む面であって、波状摩耗の波形の凸部を結ぶ仮想面上を移動することが可能になっている。つまり波状摩耗測定装置100は波状摩耗の凹凸によらず、複数のローラー12のうち2つのローラー12がレールRと接触した箇所(波状摩耗の波形の凸部)を結ぶ仮想線を含む面を基準面Sとし、その基準面Sに沿うようにレールR上を移動することができるので、この波状摩耗測定装置100は基準面SからレールRの頭頂面までの距離を測定して、波状摩耗による凹凸を連続的に測定することができる。【選択図】図1
