支持金具の一対の把持部材11,12は、上下に対向して支持パイプ2を包囲する半円弧状板部11a,12aをそれぞれ有し、一端側において互いにピン13でヒンジ結合され、他端側においてボルト14で締め付け可能に構成される。   The pair of gripping members 11 and 12 of the support metal fittings have semicircular arc plate portions 11a and 12a that are opposed to each other and surround the support pipe 2, and are hinged to each other by a pin 13 at one end side, and the other end side. The bolt 14 can be tightened.

添え板部7は、上部の把持部材11に連続するように、基端側において上部の把持部材11の半円弧状端面11bに固着される。   The accessory plate portion 7 is fixed to the semicircular arc end surface 11 b of the upper gripping member 11 on the base end side so as to be continuous with the upper gripping member 11.

吊架線支持滑車8は、添え板部7の先端側上部に、添え板部7の延長方向に相互間隔を置いて固着された一対のブラケット板15,15間に一対の滑車16と止めボルト17とを取り付けてなる。一対のブラケット板15は、水平片15aと垂直片15bとを有するほぼ転倒T字状板で構成され、水平片15aの中央で添え板部7に固着される。滑車16は、添え板部7の両側に位置して、ブラケット板15の水平片15aの両端部間に軸支される。滑車16は、添え板部の延長方向に対して直交する方向に延長する吊架線Mを乗せ受ける。止めボルト17は、ブラケット板15の垂直片15bの上端部間に挿通され、滑車16上に乗せ受けられた吊架線Mを滑車16との間に挟むように配置される。   The suspension line support pulley 8 includes a pair of pulleys 16 and a set bolt 17 between a pair of bracket plates 15, 15 fixed to the upper portion on the distal end side of the attachment plate portion 7 at an interval in the extending direction of the attachment plate portion 7. And attached. The pair of bracket plates 15 is composed of a substantially inverted T-shaped plate having a horizontal piece 15a and a vertical piece 15b, and is fixed to the accessory plate portion 7 at the center of the horizontal piece 15a. The pulley 16 is located on both sides of the accessory plate portion 7 and is pivotally supported between both end portions of the horizontal piece 15 a of the bracket plate 15. The pulley 16 carries a suspension line M extending in a direction orthogonal to the extending direction of the attachment plate portion. The set bolt 17 is inserted between the upper ends of the vertical pieces 15 b of the bracket plate 15, and is arranged so as to sandwich the suspension line M placed on the pulley 16 and the pulley 16.

上下に延線されるトロリ線Tと吊架線Mの位置を左右に調整するために、曲線引金具4と吊架線支持滑車8の位置を調整する場合には、支持金具3を支持パイプ2上で位置調整するだけで済む。   In order to adjust the positions of the trolley wire T and the suspension line M that are extended vertically to the left and right, when adjusting the positions of the curve fitting 4 and the suspension line support pulley 8, the support fitting 3 is placed on the support pipe 2. You just need to adjust the position.
