Description

トロリ線曲げ工具Trolley wire bending tool
　本発明はトロリ線曲げ工具に関するものである。 The present invention relates to trolley wire bending tools.
　トロリ線は、パンタグラフを通じて車両に集電を行う接触電線であり、その外周の上部には電線の長手方向に沿って二本の凹溝が形成されている。そして、ちょう架線の各所から吊るされた複数のハンガーが、その下端部に設けられた一対の爪によりトロリ線の二本の凹溝を挟持してトロリ線を吊架支持している。トロリ線は、このように、上部に設けられた二本の凹溝によって吊架支持されるので、外周のほぼ下半分をパンタグラフとの摺接領域として使用することができる。 The trolley wire is a contact wire for collecting a current through the pantograph to the vehicle, and in the upper part of the outer periphery thereof, two concave grooves are formed along the longitudinal direction of the wire. Then, a plurality of hangers suspended from each place of the hinge wire sandwich and support the trolley wire by sandwiching the two concave grooves of the trolley wire with a pair of claws provided at the lower end portion thereof. Since the trolley wire is thus suspended and supported by the two concave grooves provided at the top, approximately the lower half of the outer circumference can be used as a sliding contact area with the pantograph.
　ところで、トロリ線は、パンタグラフが摺接した状態で使用されるので、機械的、電気的に摩耗を生じる。このため、トロリ線は、摩耗によって寿命となる前に張り替えを行う必要があった。その際、張り替え用の新しいトロリ線はドラムに巻かれた状態で保管されているため、使用する際に丸まった形状のクセが付いている場合があった。
　また、トロリ線は、パンタグラフが摺接した状態で使用されるので、外部からの衝撃や押圧による外乱を受けやすく、これらにより既設のトロリ線に曲がりや凹凸のクセが付いている場合もあった。 By the way, since the trolley wire is used in a state where the pantograph is in sliding contact, mechanical and electrical wear occurs. For this reason, the trolley wire had to be replaced before the end of its life due to wear. At that time, since the new trolley wire for replacement was stored in a state of being wound around the drum, there was a case where it had curled shape peculiarity when used.
In addition, since the trolley wire is used in a state in which the pantograph is in sliding contact, it is susceptible to external disturbances due to external impact or pressure, which may cause bending or unevenness of the existing trolley wire. .
　トロリ線にクセがあると、列車のパンタグラフ通過時に離線して火花の発生原因となる場合があり、また、トロリ線の局所的な摩耗の原因にもなり得るので、トロリ線のクセをとるための工具により矯正が行われていた。 If there is a habit on the trolley wire, it may be separated when the train passes the pantograph, which may cause sparks, and it may also cause local wear of the trolley wire. The correction was done by the tool of.
　例えば、特許文献１の工具は、操作棒の先端部に設けられた楕円部材と、楕円部材の左右両側で操作棒の先端近傍に回動可能に設けられた一対のアーム部と、各アーム部の先端部に設けられた一対の可動ローラーと、一対のアーム部を回動させる把手アーム部とを備えている。
　そして、楕円部材をトロリ線の一方の側面に当接させると共に一対の可動ローラーをトロリ線の他方の側面に当接させた状態で把手アーム部を操作して一対のアーム部を回動させて、可動ローラーの圧接によりトロリ線のクセの矯正を行っている。 For example, the tool of Patent Document 1 includes an elliptical member provided at the tip of the operating rod, a pair of arm portions rotatably provided in the vicinity of the tip of the operating rod on both left and right sides of the elliptical member, and each arm And a handle arm portion for rotating the pair of arm portions.
Then, with the oval member in contact with one side of the trolley wire and the pair of movable rollers in contact with the other side of the trolley wire, the handle arm is operated to rotate the pair of arms. Corrects the habit of trolley wire by pressing the movable roller.
