CROSSOVER SECTION EXAMINING DEVICE OF TROLLEY WIRE

PURPOSE:To provide a crossover section examining device of trolley wires which is loaded on an electric measuring vehicle, and measures the vertical interval of two lines of trolley wires of a crossover section in the running condition of the measuring vehicle. CONSTITUTION:This crossover section examining device is composed of a linear light source provided just under a horn part 411 parallel to the horn part 411 of a pantagraph 4 for measuring of a measuring vehicle 5, and to project a slit light Lr to the upper side vertically to a reflecting surface S formed to the horn part 411; an ITV camera 7 provided by forming an adequate angle theta upward obliquely by directing to the horn part; and an image process check member to binarize the image data of the reflecting surface S in a crossover section 1C photographed by the ITV camera 7 and the image data of the lower side trolley wire 1A contacted or close to the horn part 411, and to check the condition of the vertical interval of the two lines of trolley wires. Consequently, the vertical interval h can be measured accurately in the running condition of the measuring vehicle 5 so as to decide the condition of the interval h, and it contributes to a power saving, as well as the durability of the measurement is improved compared with the conventional measuring method by a visual observation and the like.
