Description
【０００１】
【発明の属する技術分野】
本発明は電気鉄道の吊架線を可動ブラケットの主パイプへ支持するための支持装置に関するもので、水分の滞留による電食防止を目的とするものである。
【０００２】
【発明が解決しようとする課題】
図６に示す如く従来の装置は、水平主パイプＰの先端部で吊架線Ｍを支持する。そのために絶縁材製ブロックＡ，Ｂと支持金具とを用いている。ブロックＡ，Ｂは何れも方形体の対向面に吊架線Ｍを抱持可能に半円溝を設けたものである。また支持金具はブロックＡ，Ｂを収納してボルト締め可能なＵ形金具Ｕとその基部背面へ固着した円形金具Ｃとから成る。円形金具は主パイプＰへ被挿固着可能なものである。
この場合ブロックＡ，Ｂは水平面で対向しているため隙間へ雨水が滞留し、局部電流の発生によって吊架線が電食されるという問題があった。またそれとは全く別の問題として、ブロックＡ上の半円溝へ定置した吊架線が、その上へブロックＢ，ふた板Ｆをかぶせボルト締めするまでの間、ズレ出すことが多く、高所作業のこととてこのボルト締めに思いがけぬ手数のかかる難もあった。この２点を解決したい。
【０００３】
【課題を解決するための手段】
ブロックＡ，Ｂの対向面を夫々中央帯と両側帯に区分し、この３帯の表面に互い違い角度対称の段付傾斜面を形成させる。その交点には吊架線を定置可能な半円溝を設ける。半円溝は傾斜面へ穿たれるため、その壁面は一方が高く他方が低い。
雨水は傾斜面に沿うて流出し、あとは急速に自然乾燥する。また吊架線取付時には２ヵ所を溝の高壁で支持された吊架線が、中央で逆方向から高壁に支持される形になるので位置ズレを起こさない。側面から見てハの字形勾配の谷底溝へ挿入する形となるので取付作業が容易になる。
【０００４】
【発明の実施の形態】
図１に示す如くブロックＡは中央帯Ａ１が右下り、両側帯Ａ２が左下りの傾斜面となっている。吊架線挿入溝Ａ３は中央帯Ａ１では左壁が高く右壁は低い。両側帯Ａ２ではこの逆となる。従ってこの溝へ挿入された吊架線は容易にズレ出すことがない。ブロックＡ，Ｂは同一物であり、１８０度位相を変えて用いることにより、上下で直方体を形成する。
図３には吊架線が平行２本の場合のブロックＡを例示した。図４、図５は同じく吊架線２本の場合の装置を示した。即ちブロックＡ，ＢはＵ形金具１に収納され、ふた２をかぶせ、ボルト３で一体化される。Ｕ形金具１の基部背面には円形金具４が一体化されており、これへ主パイプＰを挿入して固着する。
【０００５】
【発明の効果】
両ブロックＡ，Ｂの間に水分が滞留せず、吊架線の電食を防止できる。ブロックＡの溝へ挿入された吊架線は位置ズレを起こさず、組込作業が容易となる。

BACKGROUND OF THE INVENTION
The present invention relates to a support device for supporting a suspension line of an electric railway to a main pipe of a movable bracket, and is intended to prevent electrolytic corrosion due to moisture retention.
[0002]
[Problems to be solved by the invention]
As shown in FIG. 6, the conventional apparatus supports the suspension wire M at the tip of the horizontal main pipe P. For this purpose, the insulating material blocks A and B and the support fitting are used. Each of the blocks A and B is provided with a semicircular groove on the opposing surface of the rectangular body so that the suspension wire M can be held. Further, the support metal fitting is composed of a U-shaped metal fitting U that accommodates the blocks A and B and can be bolted, and a circular metal fitting C fixed to the rear surface of the base. The circular fitting can be inserted and fixed to the main pipe P.
In this case, since the blocks A and B are opposed to each other on a horizontal plane, rainwater stays in the gap, and there is a problem that the suspended wire is eroded by generation of a local current. Also, as a completely different problem, the suspension line placed in the semicircular groove on the block A often slips out until the block B and the cover plate F are put on it and tightened with bolts. There was also an unexpected amount of difficulty in tightening the bolts. I want to solve these two points.
[0003]
[Means for Solving the Problems]
The facing surfaces of the blocks A and B are divided into a central band and a both-side band, respectively, and a stepped inclined surface having alternately symmetric angles is formed on the surface of the three bands. A semicircular groove on which the suspension wire can be placed is provided at the intersection. Since the semicircular groove is drilled into the inclined surface, one of the wall surfaces is high and the other is low.
Rainwater flows along the slope, and the rest is naturally dried rapidly. In addition, when the suspension line is attached, the suspension line supported at two places by the high wall of the groove is supported by the high wall from the opposite direction at the center, so that the positional deviation does not occur. Since it is inserted into a valley groove with a C-shaped slope when viewed from the side, the mounting operation is facilitated.
[0004]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, in the block A, the central band A1 has a right downward slope, and both side bands A2 have a left downward slope. The suspension wire insertion groove A3 has a high left wall and a low right wall in the central band A1. The opposite is true for the double-sided band A2. Therefore, the suspension line inserted into the groove is not easily displaced. Blocks A and B are the same, and form a rectangular parallelepiped at the top and bottom by changing the phase by 180 degrees.
FIG. 3 illustrates the block A in the case where there are two parallel suspension lines. 4 and 5 show the apparatus in the case of two suspension cables. That is, the blocks A and B are accommodated in the
[0005]
【The invention's effect】
Moisture does not stay between both blocks A and B, and electrolytic corrosion of the suspension wire can be prevented. The suspension line inserted into the groove of the block A does not cause a positional shift, and the assembling work becomes easy.
