Description

【０００１】
【発明の属する技術分野】
【０００２】
この発明は、狭小なトンネル内でトロリ線を支持する剛体電車線装置に関するものである。
【従来の技術】
従来、トンネル内での剛体電車線の支持方法として、特許文献１に記載されたものが知られている。この剛体電車線の支持方法は、天井に特殊金具と碍子を介してΠ型の剛体電車線を吊るものである。
【０００３】
【発明が解決しようとする課題】
上記従来の架線方式は、上下方向に大きなスペースを要するので、狭小なトンネル内に設置することができない。また電車の高速運転に対応するために２条のトロリ線を平行に吊る場合には、上下方向のみならず、延線直交方向にも大きなスペースを要するので、狭小なトンネルには対応できないという問題点があった。
この発明の課題は、狭小なトンネル内の小空間に設置でき、張力調整装置なしに、高い集電性能を維持し、堅牢なトンネル用剛体電車線装置を提供することである。
【特許文献１】

【０００４】
【課題を解決するための手段】
上記課題を解決するため、この発明においては、トンネルの天井Ｔに電車の進行方向に相互間隔をおいて支持部材１を複数固定し、これらの支持部材１に沿って、当該各支持部材１の両側下部に一対のアルミ剛体電車線２を支持する。長尺のアルミ剛体電車線２を長手方向端部において互いに電気的に接続する。これらアルミ剛体電車線２に沿って、当該アルミ剛体電車線２の下部に一対のトロリ線３を支持する。支持部材１には、碍子４と支持金具５とを具備させる。碍子４は上端においてトンネルの天井Ｔに固定し、その下端から電車の進行方向に並んで下方へ一対の支持ボルト４ｂを突出させる。この碍子４の下端の支持ボルト４ｂに支持金具５を固定する。支持金具５には、トンネルの天井Ｔに沿って電車の進行方向に水平に伸びる取付部５ａと、この取付部５ａの両端から水平方向直角にそれぞれ反対向きに延出する支持部５ｂとを具備させ、取付部５ａの中間において碍子の支持ボルト４ｂに固定し、支持部５ｂの下部にそれぞれアルミ剛体電車線２を支持する。アルミ剛体電車線２には、支持金具５の下面に沿う天板部２ａと、この天板部２ａから互いに平行に下方へ延出する一対の挟持片２ｂとを具備させて断面ほぼΠ型とし、天板部２ａの両縁を支持部５ｂに係合させて支持金具５に支持する。アルミ剛体電車線２の一対の挟持片２ｂの下端部間にトロリ線３を把持する。

【発明の実施の形態】
図面を参照して本発明の実施の形態を説明する。図は本発明に係るトンネル用剛体電車線装置を示すもので、図１は正面図、図２は側面図、図３は底面図である。
【０００６】
図において、支持部材１が、トンネルの天井Ｔに電車の進行方向に相互間隔をおいて複数固定される。これら複数の支持部材１に沿って、当該各支持部材１の両側下部に一対のアルミ剛体電車線２が支持される。アルミ剛体電車線２は、長手方向端部において互いに電気的に接続される長尺の型材である。これら各アルミ剛体電車線２に沿って、当該アルミ剛体電車線２の下部にトロリ線３が支持される。
【０００７】
支持部材１は、碍子４と支持金具５とを具備する。碍子４は、上端においてトンネルの天井Ｔに固定され、下端には支持板４ａを備え、そこから電車の進行方向に並んで下方へ突出した一対の支持ボルト４ｂを備える。この碍子４の下端に支持金具５が固定される。
【０００８】
支持金具５は、両端においてアルミ剛体電車線２を支持する。支持金具５は、トンネルの天井Ｔに沿って電車の進行方向に水平に伸びる取付部５ａと、この取付部５ａの両端から直角にそれぞれ反対向きに延出する支持部５ｂとを具備する。取付部５ａは、中間において碍子の支持ボルト４ｂにより碍子４の下端に固定される。支持部５ｂは、中間においてやや上方へ立ち上がって水平に伸び、端部において、クランプ金具５ｃとボルト、ナット５ｄによりそれぞれアルミ剛体電車線２を支持する。
【０００９】
アルミ剛体電車線２は、断面ほぼΠ型の長尺型材で、支持金具５の下面に沿う天板部２ａと、この天板部２ａから互いに平行に下方へ延出する一対の挟持片２ｂとを具備する。天板部２ａの両縁を支持部５ｂに係合させてクランプ金具５ｃにより支持金具５に支持される。一対の挟持片２ｂの下端部間にトロリ線３を把持する。
【００１０】
【発明の効果】
以上のように、本発明においては、支持金具５が、取付部５ａと支持部５ｂとを有し、ほぼＳ字状に構成されているから、碍子との十分な接続強度を保持しながら、トロリ線に直交する方向の寸法を小さくすることができ、設置スペースが制限される狭小トンネル内にも剛体電車線方式を適用可能であり、これによって電車の高速化にも対応することができるという効果を有する。

BACKGROUND OF THE INVENTION
[0002]
The present invention relates to a rigid train line device that supports a trolley line in a narrow tunnel.
[Prior art]
Conventionally, a method described in Patent Document 1 is known as a method for supporting a rigid train line in a tunnel. This method of supporting a rigid train line is one in which a saddle-shaped rigid train line is suspended from a ceiling via a special metal fitting and an insulator.
[0003]
[Problems to be solved by the invention]
The above conventional overhead wire system requires a large space in the vertical direction and cannot be installed in a narrow tunnel. In addition, when two trolley wires are suspended in parallel in order to support high-speed train operation, a large space is required not only in the vertical direction but also in the direction orthogonal to the extension line, so that it is not possible to handle narrow tunnels. There was a point.
An object of the present invention is to provide a rigid rigid rail line device for a tunnel that can be installed in a small space in a narrow tunnel, maintains high current collecting performance without a tension adjusting device, and is robust.
