Description

  The present invention relates to a device and a method for adjusting a height of a trolley wire by suspending a trolley wire from a suspension wire or an auxiliary suspension wire and changing a suspension position according to a track under construction.

Conventionally, railroad track hangers have a hanger bar that has a loop-shaped hook portion to be hung on a suspension line at the top, and a bolt that is fixed to the lower end of the hanger bar and clamps and passes through the trolley wire. A pair of ear pieces is provided (Patent Document 1).
In track switching / maintenance work, from the viewpoint of ensuring work safety and improving work efficiency, simultaneous competition work between the overhead line side and the track side is not possible. The height of the overhead wire is adjusted by changing the vertical length. Since there is a restriction on the power failure time of the overhead line for construction work, in order to shorten the work time, it is necessary to be able to adjust the height position of the trolley wire in a short time.
As the hanger that can adjust the vertical length, a hanger bar having a hook part to be hung on a suspension line and a connection bar to which the ear piece is coupled are overlapped with each other and fastened with a connection bolt, Some have a connection bar and a turnbuckle.
