To provide an inspection/measurement device with which, available at low cost though, it is possible to inspect and measure a trolley wire height with high accuracy and high reliability.SOLUTION: Provided is an inspection/measurement device that inspects and measures a trolley wire height from a vehicle travelling on a rail, the inspection/measurement device comprising a reflection plate that is provided downward of the collector head of a pantograph provided on the roof of the vehicle, a laser length measuring sensor that irradiates the reflection plate with laser light and measures the distance to the reflection plate, and an arithmetic unit that calculates the height of the trolley wire from the rail on the basis of the distance measured by the laser length measuring sensor.SELECTED DRAWING: Figure 1 【課題】 低コストでありながら、高精度かつ信頼性の高いトロリ線高さを検測できる、検測装置を提供することを目的とする。【解決手段】 軌道を走行する車両からトロリ線の高さを検査測定する検測装置であって、前記車両の屋根上に備えたパンタグラフの舟体の下方に設けた反射板と、該反射板にレーザ光を照射して該反射板までの距離を測定するレーザ測長センサと、該レーザ測長センサが測定した距離に基づいて前記軌道から前記トロリ線の高さを算出する演算装置と、を備えた検測装置。【選択図】 図１
