Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for supporting a train line including a feeder, a suspended overhead line, and a trolley line installed above a train line.
[0002]
[Prior art]
Train lines are arranged so that inspection of train lines including feeders, suspension lines, trolley lines, etc. for power supply in electric railways can be performed easily by train line inspection equipment that runs along these train lines. The overhead wire structure described is described in Japanese Patent Laid-Open No. 9-226417.
This is a structure in which two strips of feeders and suspension wires are installed substantially horizontally in parallel with each other, and a trolley wire is suspended below the suspension wire via a hanger. In addition, a trolley wire can be suspended below the feeder (thus, two trolley wires). Here, “wires” and “suspended wires” are collectively referred to as “suspended wires”.
The train line inspection device is a trolley line that avoids the trolley line by extending from the traveling section that runs on the two or one suspension line, a control section that is disposed below the trolley line, and the traveling section. And an arm connected to the control unit.
