Title (EN) GRIPPING TOOL FOR INDIRECT LIVE-WIRE WORK
(FR) OUTIL DE PRÉHENSION POUR TRAVAIL INDIRECT DE FIL SOUS TENSION
(JA) 間接活線工事用把持工具
Abstract:
(EN) Provided is a gripping tool which is for indirect live-wire work and which is capable of gripping a relatively thick electric wire and a relatively thin electric wire by using one insulated operation rod. A gripping tool 10 for indirect live-wire work according to the present invention is characterized by comprising an insulated operation rod 14, a gripping part 12 including a movable gripping part 20 and a fixed gripping part 22, an auxiliary insulated operation rod 24, and a gripping operating part 26, wherein: the fixed gripping part 22 is formed into a shape an end part of which is divided into two; the movable gripping part 20 has an arc-like curved surface 200r formed so as to come into contact with an electric wire 84 and to have an arc shape on a plane including the axial direction of the insulated operation rod 14; the fixed gripping part 22 is provided with an engagement section C having a shape bent at an obtuse angle so as to grip both the electric wire 84 having a small diameter and the electric wire 84 having a large diameter; and when the gripping part 12 is in a closed state, a fan-shaped space is formed between the arc-like curved surface 200r of the movable gripping part 20 and the engagement section C of the fixed gripping part 22.
(FR) L'invention porte sur un outil de préhension qui est destiné à un travail indirect de fil sous tension et qui est capable de saisir un fil électrique relativement épais et un fil électrique relativement mince à l'aide d'une tige de commande isolée. Un outil de préhension 10 pour un travail indirect de fil sous tension selon la présente invention est caractérisé en ce qu'il comprend une tige de commande isolée 14, une partie de préhension 12 comprenant une partie de préhension mobile 20 et une partie de préhension fixe 22, une tige de commande isolée auxiliaire 24 et une partie de commande de préhension 26 : la partie de préhension fixe 22 se présentant sous une forme dont une partie d'extrémité est divisée en deux ; la partie de préhension mobile 20 ayant une surface incurvée en forme d'arc 200r formée de façon à venir en contact avec un fil électrique 84 et à avoir une forme d'arc sur un plan comprenant la direction axiale de la tige de commande isolée 14 ; la partie de préhension fixe 22 étant pourvue d'une section de mise en prise C ayant une forme courbée selon un angle obtus de façon à saisir à la fois le fil électrique 84 ayant un petit diamètre et le fil électrique 84 ayant un grand diamètre ; et lorsque la partie de préhension 12 est dans un état fermé, un espace en forme de ventilateur étant formé entre la surface incurvée en forme d'arc 200r de la partie de préhension mobile 20 et la section de mise en prise C de la partie de préhension fixe 22.
(JA) 比較的太い電線でも比較的細い電線でも一本の絶縁操作棒で把持することを可能とする間接活線工事用把持工具を提供する。 この発明の間接活線工事用把持工具10は、絶縁操作棒14と、可動把持部20と固定把持部22とを有する把持部12と、補助絶縁操作棒24と、把持操作部26と、を備え、固定把持部22は、先端部が2つに分かれた形状に形成されており、可動把持部20は、絶縁操作棒14の軸線方向を含む平面上で円弧を描く、電線84と当接する円弧曲面200rが形成されており、固定把持部22は、小径又は大径のいずれの電線84をも把持できるように、鈍角の角度で屈曲する形状の係合部Cを備えており、把持部12が閉状態である場合には、可動把持部20の円弧曲面200rと固定把持部22の係合部Cとの間において、扇形の空間が形成されることを特徴とする。
