To provide a rail shape measurement device capable of correctly measuring a cross-sectional shape of a rail by a lightweight device having a reduced load on an operator.SOLUTION: A rail shape measurement device 1 that measures a cross-sectional shape of a rail R, Includes: a fixing part 5 that is detachably fixed to the rail R; a support part 4 that supports a measurement part 2 that measures the cross-sectional shape of the rail R; and attachment parts 15A-15C that detachably attach the support part 4 to the fixing part 5 so that the support part 4 is supported by the fixing part 5 using the fixing part 5 as a reference. The support part 4 is removed from the fixing part 5 at re-profiling of the rail R, and is attached to the fixing part 5 at shape measuring of the rail R. The attachment parts 15A-15C attach the support part 4 to the fixing part 5 so that the support part 4 is supported by the fixing part 5 at three positions. The attachment parts 15A-15C attach the support part 4 to the fixing part 5 by bringing a contact portion on the support part 4 side into contact with a contact portion on the fixing part 5 side.SELECTED DRAWING: Figure 1

    【課題】作業者の負担が小さく軽量な装置によってレールの断面形状を正確に測定することができるレール形状測定装置を提供する。【解決手段】レール形状測定装置1は、レールRの断面形状を測定する装置であり、レールRに着脱自在に固定される固定部5と、レールRの断面形状を測定する測定部2を支持する支持部4と、支持部4が固定部5に固定部5を基準として支持されるように、固定部5に支持部4を着脱自在に装着する装着部15A~15Cとを備えている。支持部4は、レールRの削正時には固定部5から取り外され、レールRの形状測定時には固定部5に装着される。装着部15A~15Cは、固定部5に支持部4が3箇所で支持されるように、固定部5に支持部4を装着する。装着部15A~15Cは、固定部5側の接触部に支持部4側の接触部を接触させることによって、固定部5に支持部4を装着する。【選択図】図1
