To measure a height and horizontal deviation of an overhead power line in a state where push-up of the overhead power line by a pantograph is reproduced without an excessive workload.SOLUTION: An apparatus for measuring a height/deviation of an overhead power line includes: a horizontal deviation measurement part 2 for measuring a horizontal deviation of an overhead power line T; a height measurement part 3 for supporting the overhead power line T at a height position of the overhead power line T, and measuring a height of the overhead power line T; and a support base 4 that is mounted on a pair of rails R, and supports the height measurement part 3. The height measurement part 3 includes: a support cylinder 31 vertically erected at a center corresponding position between the rails R, R of the support base 4; and an expandable strut 32 having a scale S1 in a vertical direction that is liftably inserted to the support cylinder 31 on the lower side, and measures the height of the overhead power line T. The expandable strut 32 is liftably provided on the support cylinder 31 by traction of a wire 52 wound around a winch 51 fixed onto the support base 4. A tension measurement apparatus 56 for measuring a push-up load against the overhead power line T of the height measurement part 3 is interposed in the middle of an extension line of the wire 52.SELECTED DRAWING: Figure 1
【課題】余計な作業負担をかけずに、パンタグラフによる架線の押し上げを再現した状態で架線の高さ及び水平偏位を測定する。【解決手段】架線の高さ・偏位測定装置は、架線Tの水平偏位を測定する水平偏位測定部2と、これを架線Tの高さ位置に支持すると共に当該架線Tの高さを測定する高さ測定部3と、 一対のレールR上に載置されて高さ測定部3を支持する支持台4とを具備する。高さ測定部3は、支持台4のレールR,R間中央対応位置に垂直に立設される支持筒31と、下部において支持筒31に昇降自在に挿入され架線Tの高さを測定するための上下方向の目盛S1を備える伸縮柱32とを具備する。伸縮柱32は、支持台4上に固定されたウィンチ51に巻かれるワイヤ52の牽引により支持筒31に対して昇降自在に設ける。ワイヤ52の延線途上に、高さ測定部3の架線Tに対する押し上げ荷重を測定するための張力測定装置56を介設する。【選択図】 図1
