Description

この発明は、剛体電車線の接続構造と接続方法の改良に関し、現場での接続工事を簡易化しつつ、施工精度を向上させるものである。   The present invention relates to an improvement in the connection structure and connection method of a rigid train line, and improves construction accuracy while simplifying connection work on site.

特許文献１には、Π型剛体電車線と称される剛体電車線が記載されている。これを図１１に示す。この剛体電車線の本体３１は、上辺３１ａと、２本の脚辺３１ｂと、下端のイヤ辺３１ｃとから構成される。上辺３１ａの中央には可撓性薄肉部３１ｄが設けられ、両脚辺３１ｂは外開きに作られ、トロリ線Ｔを挿入後、ボルト３２で締込可能である。本体３１同士の接続部では、継目板３３，３４が両本体３１，３１にまたがって脚辺３１ｂの内外側面にあてがわれ、ボルト３５で各対応脚辺３１ｂへ固着される。継目板３３，３４は短冊状で、本体３１の上辺下面とイヤ辺上面との間の方形空間（溝）３１ｅへはまり合う幅と、継目中心で左右対称の適当な長さを持ち、脚辺３１ｂを挟んで、ボルト３５で締付けられる。継目板３３，３４の上縁には、中央から長手方向左右に下がるテーパ３３ａ，３４ａが設けられており、最大幅となる中央部で本体１の溝３１ｅの幅と同じになるように構成される。   Patent Document 1 describes a rigid train line referred to as a saddle type rigid train line. This is shown in FIG. The main body 31 of the rigid train line is composed of an upper side 31a, two leg sides 31b, and a lower end ear side 31c. A flexible thin-walled portion 31d is provided at the center of the upper side 31a, both leg sides 31b are formed so as to be opened outward, and can be tightened with a bolt 32 after inserting the trolley wire T. In the connection part between the main bodies 31, the joint plates 33 and 34 are applied to the inner and outer surfaces of the leg side 31 b across the main bodies 31 and 31, and are fixed to the corresponding leg sides 31 b with bolts 35. The joint plates 33 and 34 are strip-shaped, have a width that fits into a rectangular space (groove) 31e between the upper and lower surfaces of the main body 31 and the upper surface of the ear side, and an appropriate length that is symmetrical to the center of the joint. It is tightened with a bolt 35 across 31b. Tapers 33a and 34a are provided at the upper edges of the joint plates 33 and 34 so as to be lowered from the center to the left and right in the longitudinal direction, and are configured to be the same as the width of the groove 31e of the main body 1 at the central portion that is the maximum width. The

特開平０７−９８９６号公報Japanese Patent Application Laid-Open No. 07-9896

上記従来の剛体電車線においては、継目板３３，３４の最大幅と本体３１の溝３１ｅの幅に加工差があり、継目板３３，３４の最大幅の方が大きいときは、位置合わせを行うときに継目板の中央部をヤスリで削り、調整する必要がある。ヤスリによる削り代を余計に取ると、接続部に目違い（上下段差）や角折れ（上下屈折）が生じるおそれがある。継目板３３，３４の最大幅の方が小さいときも同様の現象が生じる。また無理矢理挿入すると、変形が生じて位置合わせができない。
したがって、この出願に係る発明は、剛体電車線の本体同士を接続する際の位置合わせが容易で、高い施工精度を確保することができ、また必要な電流容量と剛性を確保しつつ、可及的な軽量化が図れる剛体電車線の接続構造と接続方法を提供することを目的としている。 In the above-mentioned conventional rigid train line, there is a processing difference between the maximum width of the joint plates 33 and 34 and the width of the groove 31e of the main body 31, and when the maximum width of the joint plates 33 and 34 is larger, alignment is performed. Sometimes it is necessary to trim the center of the seam plate with a file. If the cutting allowance by the file is taken excessively, there is a risk that a misconnection (upper / lower step) or a corner bend (up / down refraction) may occur in the connecting portion. A similar phenomenon occurs when the maximum width of the joint plates 33 and 34 is smaller. If it is inserted forcibly, deformation occurs and alignment is impossible.
Therefore, the invention according to this application is easy to align when connecting the main bodies of the rigid train lines, can ensure high construction accuracy, and as much as possible while ensuring the necessary current capacity and rigidity. An object of the present invention is to provide a connection structure and a connection method of a rigid train line that can be reduced in weight.
