PROBLEM TO BE SOLVED: To measure height of a trolley wire which is displaced in a zigzag state, by following the trolley wire easily and relatively continuously with high accuracy.SOLUTION: A height measurement device 1 comprises a first electric slider 4 capable of moving by reciprocating movement in a lateral direction on a lorry 2 which can move on rails R, R and first and second laser distance meters 6a, 6b, 6c for measuring heights of a center lowermost part and both side parts of a trolley wire T are fixed to the first electric slider 4. A sequencer 15 moves the first laser distance meter 6a to a proper measurement position by driving the first electric slider 4 until a lost event is solved, when the laser of the first laser distance meter 6a is deviated from the center lowermost part of the trolley wire T and therefore the laser of the second laser distance meter 6b (6c) is deviated from the trolley wire T, and output of the measurement data from the second laser distance meter 6b (6c) is stopped, namely the lost event occurs, for making the laser meters follow the trolley wire T.
【課題】 ジグザグ変位するトロリ線に追従してその高さを比較的連続して精度高く簡易に測定する。【解決手段】 高さ測定装置1は、レールR,R上を移動可能な台車2上に横方向に往復移動可能な第1電動スライダ4を備え、この第1電動スライダ4にトロリ線Tの中央最下部及び両側部の高さを測定する第1,第2レーザー距離計6a,6b,6cを固定する。シーケンサ15は、第1レーザー距離計6aのレーザーがトロリ線Tの中央最下部を外れることにより第2レーザー距離計6b(6c)のレーザーがトロリ線Tから外れて、第2レーザー距離計6b(6c)からの測定データの出力が途絶えるロスト事象が生じたら、第1電動スライダ4を駆動してロスト事象を解消するまで第1レーザー距離計6aを適切な測定位置に移動させることにより、トロリ線Tに追随させる。【選択図】 図4
