【産業上の利用分野】
この発明は、架空配電線のがいしへの吊架固定における電線をがいしに固定する支持具であって、ホットスティック用操作棒に各種先端工具を接続し、電線中間支持具を把持、電線の挿入、がいし頭部へ挿入仮り保持、固定させ、着脱が容易で支持部の機械的、電気的性能を維持させるために使用できる電線中間支持具に関するものである。
【０００２】
【従来の技術】
従来の架空配電線のがいしへの吊架固定は、長径間の場合は、例えば実願昭５０−２８３９３号及び実願昭５０−３０６２３号の電線バインド、特開平６−２５３４３９号公報の電線中間支持具に開示された構造のものがあるが、これは架空配電線との把持が螺旋体構造の為、ホットスティック工法を行う場合に螺旋体を電線へ巻付、巻外し用の専用先端工具が必要になり、その操作時間と熟練が要求される。
【０００３】
また、がいし相互間が隣接した狭径間の場合は、電線をがいし電線吊架溝に添わせ、ビニル被覆された軟銅細線を用い、電線とがいし頭部顎部を、電気工事に定められた規定方法で、手工具であるペンチ等により締め込みながら縛る手作業を実施している。いわゆるホットスティック工法で絶縁操作棒に連結された先端工具により電線をがいしに固定することが不可能な状況であり、間接活線工法において使用できなかった。
【０００４】
【発明が解決しようとする課題】
そこで案出されたのが本発明であって、その目的としては、ホットスティック工法で用いる絶縁操作棒と各電気工事会社の高所作業車に配備されている把持式先端工具のみで、電線をがいしに固定する作業をワンタッチ方式で固定及び取外し作業を容易に行うことができる間接活線作業用の電線中間支持具を提供するものである。
【０００５】
【課題を解決するための手段及び作用】
すなわち、架空配電線のがいし固定方法として、長径間には先願に開示された電線バインド、電線中間支持具を、狭径間にはビニル被覆された軟銅細線による手作業を行っているが、上記方法をホットスティック工法用操作棒、配備された把持先端工具を用い、単純操作により電線をがいしに固定することが可能な電線中間支持具を提供することにある。
【０００６】
この電線中間支持具は、ホットスティック工法用操作棒と先端工具により把持し、電線の挿入、がいし頭部への挿入、仮り保持させる保持機能と、がいし顎部にストッパーを接触させがいしに固定する固定機能と、中間電線支持金具の脱落を防止するストッパーによるロック機能、電線挿入溝による電線挿入方向への移動防止のための電線移動防止機能とを備えている。
【０００７】
また、この電線中間支持金具は操作棒、先端工具により把持し電線挿入、がいし挿入、仮り固定、がいしへの固定、脱落防止のためのストッパー移動によるロック機構により、取り付け、取り外し作業を容易かつ短時間に作業することができるようになっている。
【０００８】
【実施の形態】
次いで、この発明の実施例について、図面を参照しながら以下に説明する。
図１には、本発明の電線中間支持具（１）を用い、電線ａをがいしｂの電線吊架溝ｃに添わせ、電線中間支持具（１）をがいしｂの顎部ｄに一対のストッパー（２）により固定した状態を示し、図１（イ）はその平面図、同（ロ）はその正面図である。また、図２には、電線中間支持具（１）をがいしｂに固定した右側面図を示し、図３には、電線中間支持具（１）のストッパー（２）の閉状態と開状態におけるストッパー（２）移動を平面図に示し、さらに図４には、その右側面図を示す。なお、図５には一対のストッパー（２）の開側いわゆるがいし挿通穴（７）を形成させた状態の平面図を示す。
【０００９】
電線中間支持具（１）の上部には、電線ａを容易に遊通挿入できる電線挿入ガイド（４）と、電線ａが電線方向に移動しないよう内面に電線ａの被覆を傷めない凹凸状の電線把持機能を有した電線挿入溝（３）を設けてある。電線中間支持具（１）のがいしｂへの固定は、ストッパー（２）の移動操作により実施し、そのストッパー（２）の開閉移動は一対のピン（５）を支点に旋回移動し、その移動はストッパー（２）に設けられた弦状の旋回溝（６）の範囲、いわゆる一対のストッパー（２）が開放端で、がいしｂの頭部ががいし挿通穴（７）に容易に挿入できる位置に、またストッパー（２）の開端はがいしｂの顎部ｄとの固定位置にある。
【００１０】
また、閉端のロック機構は、旋回溝（６）閉端側にロック穴（８）を設け、ストッパー（２）閉端部いわゆるがいしｂの顎部ｄ側への移動により、ロックピン（９）の軸部がロック穴（８）へ遊通し固定されることになる。ロックピン（９）は常にスプリング（１０）によりロック穴（８）より外れない方向に作用しており、ロックピン（９）がロック穴（８）より挿脱することのないロック機能を有している。又、ロックピン（９）の解除は、ストッパー（２）、ロック穴（８）より挿脱する方向に操作することにより、ロック機能が解除され、ストッパー（２）はピン（５）を支点に旋回し、一対のストッパー（２）はがいし挿通穴（７）を形成しがいしｂの頭部より電線中間支持具（１）が挿脱可能になる。
【００１１】
以上に説明した第一実施例の電線中間支持具（１）は、ホットスティック工法で用いる絶縁操作棒と把持式先端工具により、中間支持具（１）の一対のストッパー（２）を開放端にセットし、電線挿入溝（３）の両端外部、又はストッパー（２）の一部を把持し、予め吊架された電線ａのがいし固定点に空送、電線挿入ガイド（４）に電線ａを遊通挿入し、がいし挿通穴（７）をがいしｂの頭部へ挿入し、電線中間支持具（１）をがいしｂに押入れ、いわゆる電線ａを電線挿入溝（３）に挿入させ、把持式先端工具によりストッパー（２）をがいしｂの顎部ｄ側へ移動させ、ロックピン（９）がストッパー（２）、ロック穴（８）へ挿入、片側のストッパー（２）も同様移動させロックさせる。
【００１２】
なお、電線中間支持具（１）の取外しは、同じく絶縁操作棒と把持式先端工具により、ロックピン（９）をストッパー（２）、ロック穴（８）より挿脱側に押上げ、ストッパー（２）を開放端に移動、他のストッパー（２）も同じく開放端に移動、すなわち図５に示すがいし挿通穴（７）を形成させ、把持式先端工具により電線中間支持具（１）の一部を把持し、取外し回収することになる。
【００１３】
図６から図１０は本発明の第二実施例を示し、６図には電線中間支持具（１１）を用い、電線ａをがいしｂの電線吊架溝ｃに添わせ電線中間支持具（１１）をがいしｂの頭部へ挿入し、顎部ｄに一対のストッパー（１２）により固定した状態を示し、図６（イ）はその平面図、同（ロ）はその正面図であり、図７はその右側面図である。図８には電線中間支持具（１１）の平面図、図９にはストッパー（１２）の閉状態の一部破断右側面図、図１０にはストッパー（１２）の開放状態の一部破断右側面をそれぞれ示す。
【００１４】
電線中間支持具（１１）の上部中央には、電線ａを容易に遊通挿入できる電線挿入ガイド（１３）と、電線ａが電線方向に移動しないよう内面に電線ａの被覆を傷めない凹凸状の電線把持機能を有した電線挿入溝（１４）を設けてある。
【００１５】
電線中間支持具（１１）のがいしｂへの固定は、ストッパー（１２）の移動操作により実施し、そのストッパー（１２）の開閉移動は、平行に設けられた一対のピン（１５）によりストッパー（１２）が平行移動し、その移動はストッパー（１２）に設けられたスライド穴（１６）範囲、いわゆる一対のストッパー（１２）の開放端でがいしｂの頭部ががいし挿通穴（１７）に容易に挿入できる位置となり、ストッパー（１２）の閉端はがいしｂ、顎部ｄとの固定位置であるストッパー（１２）の閉端ロック機構はコの字型のロックピン（１８）がストッパー（１２）閉端部いわゆるがいしｂの顎部ｄ側への移動により、ロック穴（１９）へ遊通しロック固定される。
ロックピン（１８）は常にスプリング（２０）によりロック穴（１９）側に作用しており挿脱することのないロック機能を有している。又、ロックピン（１８）の解除はコの字型ロックピン（１８）の中央把持部（２１）を引張ることにより、ストッパー（１２）両端がストッパー（１２）ロック穴（１９）より挿脱され、ロック機能が解除され、ストッパー（１２）が開放側に移動しがいし挿通穴（１７）が形成され、がいしｂの頭部より電線中間支持具（１１）が挿脱可能になる。
【００１６】
以上に説明した第二実施例の電線中間支持具（１１）は、第一実施例と同じくホットスティック工法で用いる絶縁操作棒と把持式工具により電線中間支持具（１１）の一対のストッパー（１２）を開放端にセットし、把持部（２１）を把持し、予め吊架された電線ａのがいし固定点に空送、電線挿入ガイド（１３）に電線ａを遊通挿入し、がいし挿通穴（１７）をがいしｂの頭部へ挿入、電線中間支持具（１１）をがいしｂに押入れ、いわゆる電線ａを電線挿入溝（１４）に挿入させ、把持式先端工具によりストッパー（１２）をがいしｂの顎部ｄ側へ移動、ロックピン（１８）がストッパー（１２）、ロック穴（１９）へ挿入、片側のストッパー（１２）も同様に移動させロックさせる。
【００１７】
なお、電線中間支持具（１１）の取外しは同じく絶縁操作棒と把持式先端工具により、把持部（２１）を把持引張ることにより、両端部のロックピン（１８）がロック穴（１９）より同時に挿脱し、一対のストッパー（１２）ががいし挿通穴（１７）が形成され、把持式先端工具により取外し回収することになる。したがって、がいしｂに電線ａを固定する第一実施例の電線中間支持具（１）、第二実施例の電線中間支持具（１１）において、ホットスティック用絶縁操作棒と把持式先端工具又はそれに類した先端工具により、把持、空送、挿入、固定、取付および取外しが容易に且つ短時間に実施できるようになっている。
【００１８】
【発明の効果】
以上のように架空配電線における長径間、狭径間いずれにおいても、ホットスティック工法用操作棒、既に配備されている把持式又はそれに類した先端工具を用い、電線中間支持具によれば、作業者の手元においてがいし挿通穴を形成、セットし把持し電線、がいし固定点まで移動、電線を挿入、がいしに仮り固定、ストッパー移動によりがいしの顎部に固定、ロックピンによるロックが可能であり、取外しもロック解除により、上述する絶縁操作棒により取外し、手元回収が可能である広範囲に使用できる電線中間支持具であり、又作業者においては単純で安全性が高く、且つ取付、取外し時間の効率化が計れ、確実に電線をがいしに固定する支持具として電気的、機械的に信頼性の高い極めて実用性に優れた特徴を有したものである。
