Description

【０００１】
【発明の属する技術分野】
本発明は、高圧配電線路における間接活線工法において、電信柱や鉄塔に配設された変圧器、架線係止具等の取付金具を、作業車や地上等から遠隔操作棒で、締め付けたり、緩めたりする際に使用する遠隔操作具およびその回転伝達具に関するものである。
【０００２】
【従来の技術】
一般に、電柱や鉄塔の高所に配設された変圧器、架線係止具等の取付金具（以下、取付金具と記す）を、作業車や地上等から遠隔操作棒で、締め付けたり、緩めたり（以下これらの作業を単に締め付け作業等と記す）する際には、遠隔操作棒の先端に、フック、六角ソケット、スパナ等の工具（以下、先端工具と記す）を取り付けて、当該遠隔操作棒の手元で操作して、当該先端工具を回動し、締め付け作業等を行っていた。
【０００３】
しかし、先端工具は、当該遠隔操作棒を中心軸にして、当該中心軸上を回動するだけの構造であるため、取付金具と遠隔操作棒との角度により、当該取付金具の締め付け作業等のしやすさが異なり作業効率の悪いものであり、又、この作業しやすい角度を確保するために、作業者に無理な姿勢を強いたり、作業車の停車位置や作業台の位置を種々頻繁に変更しなければならない等の問題があった。
【０００４】
【発明が解決しようとする課題】
そこで本発明は、遠隔操作棒の先端への先端工具の取付角度を自由に変えることができ、作業者に無理な姿勢を強いることなく、締め付け作業等が容易な回転伝達具及びそれを使用した回転伝達方法を提供することを目的とするものである。
【０００５】
【課題を解決するための手段】
上記目的を達成するため、本発明に係る回転伝達具は、下記の通りである。
【０００６】
先端工具を取り付ける取付部材を先端に、ベベルギアである前ギアを後端にそれぞれ装着した前軸杆を回転自在に取り付けた前連結体と、前端にベベルギアである後ギアを装着し、後端に連結部を有する後軸杆を回転自在に取り付けた後連結体と、ベベルギアである中ギアを軸支する中軸杆を備えた中連結部材とからなり、中連結部材は、中心に軸孔が穿設された筒状の内中軸受と、中心に軸孔が穿設され外周面に突設された突環に軸穴が形成された筒状の外中軸受とを備え、中軸杆が内中軸受の軸孔に挿通され、内中軸受が外中軸受の軸孔に挿通されるとともに、前軸杆が外中軸受の軸穴に遊嵌状態で装着され、軸支されることにより、同心位置にある後ギアと前ギアとを、軸心がこれらに対し直角方向にある中ギアを介して噛み合わせ、前連結体と後連結体とを中軸杆で回動自在に連結し、後連結体と前連結体を中軸杆を中心にした所望の角度で固定した状態で、後連結体の後軸杆の回転を、後ギア、中ギア、前ギア、取付部材へと順次伝達して、この取付部材を回転させるようにした構成である。
【０００７】
そして、この回転伝達具を介して先端工具を遠隔操作棒に取り付けて使用するものである。
【０００８】
すなわち、先端に先連結部を、中間部に絶縁性を有する把持部を、後端付近にギアボックスを、後端に入力後端部をそれぞれ設け、回転力を伝達する回転軸杆を回動自在に内装してなる遠隔操作棒の該先連結部に、上記発明の回転伝達を連結し、この把持部の適宜箇所を手で握って遠隔操作棒を操り、ギアボックス又は入力後端部から回転力を入力して当該回転軸杆を回転させ、この回転軸杆の回転を、回転伝達具の後軸杆、後ギア、中ギア、前ギア、前軸杆、取付部材へと順次伝達し、この取付部材に取り付けた先端工具を回転させるように構成したことを特徴とする遠隔操作具である。

【００２５】
そして、後連結体５は、図５に示したように、後基体３２の嵌挿孔３９に軸受３３を嵌挿し、該軸受３３に後軸杆３１を後基体３２の小径孔４０側から挿入して、軸受３３の内レース６０に後軸杆３１の段部３６を接当させて、後軸杆３１を後基体３２に回転自在に取り付け、この後軸杆３１の先端部に後ギア３４を当該後軸杆３１と一体となるように装着し、調節部材４８の基部５０のねじ部５５を後基体３２の上板部４３のねじ孔４７に螺着してなるものである。
【００２６】
中連結部材６は、図５に示したように、ナット６５、ワッシャ６６、外中軸受６７、内中軸受６８、前軸環６９、中ギア７０、中軸環７１及び中軸杆７とからなるものである。
【００２７】
外中軸受６７は、縦中央に軸孔７２を穿設してなる筒状体で、当該筒状体の下前外周面に突環７３を突設して、円形の軸穴７４を形成してなるものである。
【００２８】
内中軸受６８は、大径部７５の上方に小径部７６を連設して段部７７を形成し、縦中央に軸孔７８を穿設してなる円筒状体である。
【００２９】
前軸環６９は、滑り性に優れた合成樹脂製で、筒状の胴部７９の端外周面に座部８０を連設し、中央に軸孔８１を設けてなるものである。
【００３０】

【００３３】
次に、上記回転伝達具の組立方法について説明する。
【００３４】
前連結体４の前軸杆８の小径部１６を、前軸環６９の軸孔８１に挿入し、前軸環６９の座部８０を前ギア１１に接当させ、当該小径部１６の外周面を前軸環６９の胴部７９で覆うように、前連結体４の小径部１６に前軸環６９を遊嵌状態で装着する。
【００３５】
中ギア７０の軸孔８３に中軸環７１の胴部８４を挿入し、中軸環７１の座部８５を中ギア７０の軸部８２の端面に接当させ、中ギア７０の軸孔８３に中軸環７１を遊嵌状態で装着する。
【００３６】
この中ギア７０に装着した中軸環７１と、前連結体４の下板部２０の内側の軸支孔２４とが連通するように、且つ、前ギア１１と中ギア７０とを噛み合わせた状態で、前連結体４の下板部２０の内側に中ギア７０を配設する。
【００３７】
前連結体４の小径部１６に装着した前軸環６９の胴部７９に、外中軸受６７の軸穴７４をはめ込んで、前連結体４の上下板部１９、２０の軸支孔２３、２４と外中軸受６７の軸孔７２とを連通させ、この状態を保持したまま、内中軸受６８の小径部７６の先端を、前連結体４の下板部２０の軸支孔２４から、中軸環７１の軸孔８６、外中軸受６７の軸孔７２及び上板部１９の軸支孔２３に順次それぞれ挿通して、中軸環７１を介して中ギア７０が、前軸環６９を介して前連結体４の小径部１６を外中軸受６７の軸穴７４に保持した状態で当該外中軸受６７が、内中軸受６８によりそれぞれ軸支され、この内中軸受６８が前連結体４の上下板部１９、２０の軸支孔２３、２４間に遊嵌状態で嵌挿される。
【００３８】
この前連結体４の上下板部１９、２０間を後連結体５の上下板部４３、４４間で挟むようにをそれぞれ重ね、後ギア３４を中ギア７０と噛み合わせ、各上下板部１９、２０、４３、４４の各軸支孔２３、２４、４５、４６を連通させた後、中軸杆７のねじ部８９を後連結体５の下板部４４の軸支孔４６から、内中軸受６８の軸孔７８、後連結体５の上板部４３の軸支孔４５に順次挿通し、後連結体５の上板部４３から突出した中軸杆７のねじ部８９にワッシャ６６をはめ、ナット６５を螺着し、後連結体５の調節部材４８の係止杆５１を所望の前連結体４の調節孔２５に挿入係止させる。
【００３９】
これにより、前連結体４が内中軸受６８に軸支され、この内中軸受６８を後連結体５の上下板部４３、４４で挟持するように、内中軸受６８を介して中軸杆７で軸支して、前連結体４と後連結体５とを中軸杆７で回動自在に軸支し、調節部材４８で後連結体５と前連結体４を中軸杆７を中心にした所望の角度で固定した状態で、後連結体５の後軸杆３１の回転が、後ギア３４、中ギア７０、前ギア１１へと順次伝達され、この前ギア１１と前軸杆８を介して一体化された取付部材１２が回転するように組み立てられる。
【００４０】
ここで、外中軸受６７は、内中軸受６８の段部７７と前連結体４の上板部１９の下面とで挟んだ状態で内中軸受６８に軸支され、この外中軸受６７の軸穴７２に前軸環６９を介して、前連結体４の前軸杆８の小径部１６を軸支しているため、中ギア７０の回転が前ギア１１に伝達される際に、当該小径部１６が浮き上がることなく回転でき、当該回転の伝達が確実かつ円滑に行えるものである。
【００４１】
次に、上記回転伝達具に連結して使用する遠隔操作具は、二軸型と一軸型とがあるが、二軸型を中心にして以下に説明する。
【００４２】
遠隔操作具の遠隔操作棒３は、図８及び図９に示したように、先端工具２を取り付けた回転伝達具１（図示省略）を着脱自在に取り付け、回転軸杆８９からの回転力を当該回転伝達具１を介して先端工具２に伝達する先連結部９０を前ブリッジ９１に設け、この前ブリッジ９１の先連結部９０と後方の後ブリッジ９２とで回転軸杆８９の前方を回転自在に軸支し、この前後ブリッジ９１、９２間に外周面が絶縁性を有する前把持部９３を当該回転軸杆８９と平行に配設し、後ブリッジ９２の後方に絶縁性を有する中把持部９４を連設し、中把持部９４内に回転軸杆８９を回転自在に内装し、この中把持部９４の後端にギアボックス９５を取り付け、このギアボックス９５の後端に絶縁性を有する後把持部９６を連結し、この後把持部９６の後端に入力後端部９７を設け、後把持部９６に回転軸杆８９を回転自在に内装してなるものである。
【００４３】
すなわち、先連結部９０は、前ブリッジ９１の前方に突設した円筒状体で、先端外周面に係止部材９８を配設し、軸方向に挿入口９９を設けてなるものである。
【００４４】
この先連結部９０に回動自在に軸支されている回転軸杆８９の先端には、先連結部９０の挿入口９９と同軸に連通する六角形の先嵌合穴１００を、回転軸杆８９の先端軸方向に設けてなるものである。
【００４５】
前ブリッジ９１後方から後ブリッジ９２前方にかけて露出した回転軸杆８９は、その外周面に絶縁材を被覆すると共に、前方から水切鍔１０１及び限界鍔１０２を所定間隔に配設してなるものである。
【００４６】
この回転軸杆８９を軸支した後ブリッジ９２の後方には、当該回転軸杆８９を回動自在に内装する中把持部９４を連設し、外周面が絶縁性を有する中把持部９４の後端にギアボックス９５を取り付けてなるものである。
【００４７】
このギアボックス９５には、中把持部９４に内装した回転軸杆８９に、ベベルギアからなる軸ギア１０３を一体に回転するように配設し、ベベルギアからなる入力口１０４を有する入力ギア１０５をこの軸ギア１０３と噛み合わせて回動自在に配設してなる。
【００４８】
このギアボックス９５の後端に絶縁性を有する後把持部９６を取り付け、この後把持部９６の後端に入力後端部９７を設け、ギアボックス９５に軸支された回転軸杆８９を後把持部９６に回動自在に内装し、この回転軸杆８９の後端に六角形の後嵌合穴１０６を設け、この後嵌合穴１０６が露呈するように回転軸杆８９の後端を入力後端部９７に軸支してなるものである。
【００４９】
ギアボックス９５の入力口１０４や入力後端部９７の後嵌合穴１０６は、これらにラチェットハンドル１０８（図１０参照）を差し込み、このラチェットハンドル１０８を回転させることにより、この回転力が回転軸杆８９に伝達され、この回転軸杆８９の回転により先連結部９０に取り付けた回転伝達具１の後連結体５の後軸杆３１が回転し、さらにこの回転力が、後ギア３４、中ギア７０、前ギア１１、前軸杆８、取付部材１２へと順次伝達され、この取付部材１２に取り付けた先端工具２が回転するものである。
【００５０】
ここで各把持部９３、９４、９６は、吸湿性の少ないエポキシ樹脂系強化プラスチック（ＦＲＰ）からなる絶縁性筒状体で、降雨時対策として先端の先連結部９０と限界鍔１０２との間に水切りのための水切鍔１０１を配設し、水切鍔１０１の前方に撥水性に優れたテフロンチューブ１０７を配設してなるものである。
【００５１】
限界鍔１０２は、把持部と把持部以外の部分とを区別を明らかにするためのもので、水切鍔１０１と同様に軟質の合成ゴム製である。
【００５２】
又、当該遠隔操作棒３は、その絶縁性を確保するため、その各把持部９３、９４、９６の内部の両端には、詰栓を行い、浸水を防ぐために接着剤で各部をコーキングして、回転軸杆８９の回動を阻害しないように、十分な防水処理を施している。
【００５３】
次に、上記回転伝達具１の使用方法について、二軸型の遠隔操作具を使用する場合で説明する。
【００５４】
図６に示したような、フック１０９を一体化した先端工具のプラグ部１１０を、当該回転伝達具１の取付部材１２に差し込み、前連結体４の六角形の雌部１７に先端工具２の六角柱状の雄部１１１を嵌合させて、一体に回転するように先端工具２を当該回転伝達具１の前連結体４に取り付ける。
【００５５】
後連結体５の調節部材４８の座頭部４９をコイルバネ５２の弾発力に抗して引き上げて、当該調節部材４８の係止杆５１を前連結体４の調節孔２５から抜き、前連結体４と後連結体５とを中軸杆７を中心にして回動自在の状態とし、前連結体４が後連結体５に対して所望の角度（３０°、６０°、９０°等）にした後、該座頭部４９を引き上げるのを止めると、コイルバネ５２の弾発力により係止杆５１が弾発して、所望の位置の調節孔２５に挿入係止し、図７に示したように、前連結体４が後連結体５と所望の角度で固定された状態となる。
【００５６】
また所望の角度としては３０°、６０°、９０°を例示しているが、それに限定されるものではなく、仕様により調整孔２５の位置を変えることで任意の角度に固定することができる。
【００５７】
遠隔操作棒３の先連結部９０の係止部材９８のつまみ部１１２をコイルバネの弾発力に抗して引き上げた状態で、当該係止部材９８の小径の杆部１１３が後連結体５の基部３８の切込部４１に沿って進入するように、当該後連結体５の連結孔３７に遠隔操作棒３の先連結部９０を挿入し、当該つまみ部１１２を引き上げるのを止めて、コイルバネの弾発力でつまみ部１１２を下げ、後連結体５の係止孔４２に遠隔操作棒３の係止部材９８を係止させ、且つ、後連結体５の後軸杆３１の連結部３５を遠隔操作棒３の回転軸杆８９の先嵌合部１００に嵌合させて、遠隔操作棒３の回転軸杆８９と後連結体５の後軸杆３１とを一体に回動するように連結させて、後連結体５の基部３８を遠隔操作棒３の先連結部９０に取り付け、図７に示した状態とする。
【００５８】
そして、締め付け作業等を使用とする取付金具に、各把持部９３、９４、９６の適当な箇所を手で握って遠隔操作棒３を操り、当該先端工具２のフック１０９を引っかけた後、遠隔操作棒３のギアボックス９５の入力口１０４又は入力後端部９７の後嵌合穴１０６に、これらにラチェットハンドル１０８を差し込み、このラチェットハンドル１０８を回転させることにより、この回転力が回転軸杆８９に伝達され、この回転軸杆８９の回転が、回転軸杆８９に連結した当該回転伝達具１の後連結体５の後軸杆３１、後ギア３４、中ギア７０、前ギア１１、前軸杆８、取付部材１２へと順次伝達され、この取付部材１２に取り付けた先端工具２のフック１０９が回転し、取付金具を回し、当該締め付け作業等を完了する。
【００５９】
このとき、前連結体４の前軸杆８の取付部１４に六角形の雌部１７を形成し、この雌部１７に先端工具２の六角柱状の雄部１１１を嵌合させているため、前軸杆８が回転したとき、その回転力が確実に先端工具２に伝達されるものである。
【００６０】
前記実施の形態では、遠隔操作棒を二軸型の例で説明したが、一軸型の遠隔操作棒を使用してもよい。
【００６１】
すなわち、図１０及び図１１に示したように、前把持部を前後ブリッジ間に設けるのではなく、当該前後ブリッジを省略し、中把持部と前把持部とを一体化し、先端に先連結部１１４を設けた前把持部１１５の後端にギアボックス１１６を設け、このギアボックス１１６の後端に絶縁性を有する後把持部１１７を連結し、この後把持部１１７の後端に入力後端部１１８を設け、これら先連結部１１４、ギアボックス１１６及び入力後端部１１８で回転軸杆１１９を回動自在に軸支した状態で、回転軸杆１１９を前把持部１１５及び後把持部１１７に内装したものとしてもよい。
【００６２】
前記実施の形態では、先端工具２としてフック１０９を取り付けた例で説明したが、このフックの代わりに六角ソケット、スパナ等も使用できる。
【００６３】
前記実施の形態では、先端工具２を着脱自在に取り付けるために取付部材１２としてカプラーを使用した例で説明したが、先端工具２が着脱自在に取り付けられればよく、螺着等の手段でもよく、その取付構造はカプラーに限定するものではない。
【００６４】
前記実施の形態では、前連結体４の雌部１７、後連結体５の連結部３５、遠隔操作棒３の先嵌合穴１００、後嵌合穴１０６、フック１０９の雄部１１１の形状を六角形で説明したが、着脱自在に取り付けられ、回転をスリップすることなく確実に伝達できればよく、その形状は、これらに限定するものではない。
【００６５】
前記実施の形態では、調節部材４８の係止杆５１を調節孔２５に挿入係止させることで、前連結体４と後連結体５との角度を調節固定した例で説明したが、調節した角度を維持固定する手段は、これに限定するものではない。
【００６６】
すなわち、前連結体４の上下板部１９、２０の軸支孔２３、２４付近の外周面と、後連結体５の上下板部４３、４４の軸支孔４５、４６付近の内周面とに、小さな突起を多数突設した粗面を形成し、これらが互いに接触するようにして、中軸杆７のボルト６５を緩めて所望角度にした後を、再び中軸杆７のボルト６５を締めて固定するようにしてもよい。
【００６７】
【発明の効果】
以上の説明から明らかなように本発明に係る回転伝達具は、以下に列挙する実用上の様々の優れた効果を有する。
【００６８】
