PROBLEM TO BE SOLVED: To provide an in-tunnel trolley wire support device which can support a trolley wire without receiving a constriction in an extension line direction of the trolley wire, and can effectively utilize a narrow and small upper space.SOLUTION: A support rod P is horizontally supported to left-and-right both sides of a ceiling part C of a tunnel via a support insulator G. The support rod P is made to be telescopic by making a fixing pin Pb penetrate a plurality of adjustment holes Ph which are aligned in a longitudinal direction. A trolley wire support device 1 is attached to the support rod P. The support rod P is made to penetrate an attachment member 2, and the attachment member 2 is fixed to an intermediate part of the support rod P by inserting the length adjustment fixing pin Pb into the attachment member together with the support rod P. A trolley wire M is placed on a pair of opposing support pulleys 4, 4 so as to be movable to the extension line direction. A turning plate part 9 for connecting a pair of brackets 10, 10 for pivoting the support pulleys 4, 4 is supported to a lower part of the attachment member 2 so as to be turnable to a horizontal direction so that the support rod P is sandwiched therebetween. The support pulleys 4, 4 are made to follow the extension line direction of the trolley wire M with respect to the support rod P.SELECTED DRAWING: Figure 1
【課題】 吊架線の延線方向に制約を受けることなく支持でき、狭小な上部スペースを有効に活用できるトンネル内吊架線支持装置を提供する。【解決手段】 トンネルの天井部Cの左右両側に支持碍子Gを介して支持杆Pを水平に支持する。支持杆Pは、長手方向に並ぶ複数の長さ調整孔Phに固定ピンPbを貫通させて伸縮可能にする。支持杆Pに吊架線支持装置1を取り付ける。取付部材2に支持杆Pを貫通させ、長さ調整用の固定ピンPbを支持杆Pもろとも差し込んで支持杆Pの中間部に取付部材2を固定する。対向する一対の支持滑車4,4に吊架線Mを延線方向へ移動可能に載せる。支持杆Pを相互間に挟むように支持滑車4,4をそれぞれ軸支する一対のブラケット10,10を連結する旋回板部9を取付部材2の下部に水平方向に回動可能に支持する。支持杆Pに対する吊架線Mの延線方向に支持滑車4,4が追随する。【選択図】図1
