To provide a rail inspection equipment by which an inspection to test if a set location of a guide rail is in a proper range can be performed based on a behavior of a truck.SOLUTION: A rail inspection device 1 has a truck 10 which travels in a drive direction X along a pair of a travel rail 80 and a guide rail 83. The rail inspection device 1 has a determination unit which executes a contact timing determination process, a curve approach timing determination process and a rail inspection process. The contact timing determination process is a process to determine a contact timing which is a timing for a guide wheel 40 to contact with the guide rail 83, the curve approach timing determination process is a process to determine a curve approach timing at which a right front wheel 24 and a left front wheel 23 go into a curve section 72 from a straight section 71, and the rail inspection process is a process to determine if a location of the guide rail 83 is in a proper range or not based on whether the curve approach timing is before or after the contact timing.SELECTED DRAWING: Figure 3

    【課題】案内レールの設置位置が適正範囲内であるか否かの検査を、台車の挙動に基づき行うことが可能なレール検査装置を実現する。【解決手段】レール検査装置1は、一対の走行レール80及び案内レール83に沿って走行方向Xに走行する台車10を備える。レール検査装置1は、接触時期判定処理とカーブ進入時期判定処理とレール検査処理とを実行する判定部を更に備える。接触時期判定処理は、案内輪40が案内レール83に接触した時期である接触時期を判定する処理であり、カーブ進入時期判定処理は、右前輪24及び左前輪23が直線区間71からカーブ区間72に入った時期であるカーブ進入時期を判定する処理であり、レール検査処理は、カーブ進入時期と接触時期との前後関係に基づいて、案内レール83の設置位置が適正範囲内であるか否かを判定する処理である。【選択図】図3
