Description

本発明は、連結保持具に関し、詳しくは、切断する電線を切断しない電線に連結して保持させる道具に関する。   The present invention relates to a connection holder, and more particularly to a tool for connecting and holding an electric wire to be cut to an electric wire that is not cut.

高圧配電線に自動開閉器等を設置する際には、制御用電源として両電源変圧器を配置する場合があり、この両電源変圧器は、その設置装置の電源側と負荷側のそれぞれから高圧引下線を受電可能に接続されて、電力を設置装置に適した電圧に変圧して電力供給するようになっている。
この両電源変圧器は、高圧配電線との間に切り離し可能にカットアウトを介在させていない環境で交換する際には、一方の高圧引下線を切断しても他方の高圧引下線からの電力供給が可能である。このことから、切断端部は高電圧が印加されている充電部となって露出する状態となるので、計画的に停電させて交換作業を行なう必要がある。 When installing an automatic switch or the like on a high-voltage distribution line, a double-power transformer may be arranged as a control power source, and this double-power transformer is a high voltage from each of the power supply side and load side of the installation device. The underline is connected so as to be able to receive power, and the power is transformed to a voltage suitable for the installation apparatus and supplied.
When this dual power transformer is exchanged in an environment where no cutout is interposed between the high voltage distribution line and the high voltage distribution line, the power from one high voltage underline can be Supply is possible. For this reason, the cut end portion is exposed as a charged portion to which a high voltage is applied. Therefore, it is necessary to perform a replacement operation with a planned power failure.

しかしながら、夏季など停電させること自体が難しい場合には、切断した高圧引下線を保持して作業することが考えられる。
しかし、単に切断する高圧引下線にクリップ状の把持部材を取り付けたとしても、端部が充電部となっている切断後の高圧引下線が自由に動いてしまうことを抑えることができない（例えば、特許文献１〜３）。 However, when it is difficult to stop the power supply itself such as in the summer, it is conceivable to work while holding the cut high voltage underline.
However, even if a clip-shaped gripping member is attached to a high-voltage underline that is simply cut, it is not possible to prevent the high-pressure underline after cutting whose end is a charging part from freely moving (for example, Patent Documents 1 to 3).

以下、図面を参照して、本発明の実施形態について詳細に説明する。図１〜図５は本発明に係る連結保持具の一実施形態を示す図である。
図１において、連結保持具１０は、電柱ＵＰに設置する両電源変圧器ＴＷを交換する際に使用する間接活線作業用の補助道具である。この連結保持具１０は、高圧配電線の本線である送電線（把持対象）Ｄを把持する第１把持部１１と、両電源変圧器ＴＷに接続する送電線Ｄからの分岐線である高圧引下線（把持対象）ｄを把持する第２把持部２１と、これら第１、第２把持部１１、２１の双方を繋いで連結状態を維持するワイヤ（連結線状部材）Ｗと、このワイヤＷを巻いて長さを調整することで第１、第２把持部１１、２１の間の離隔間隔を調整する調整部３１と、を備えて構成されている。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1-5 is a figure which shows one Embodiment of the connection holder which concerns on this invention.
In FIG. 1, the connecting holder 10 is an auxiliary tool for indirect hot-wire work used when the dual power transformer TW installed on the utility pole UP is replaced. The connection holder 10 includes a first holding portion 11 that holds a transmission line (grip target) D that is a main line of a high-voltage distribution line, and a high-voltage drawing that is a branch line from the transmission line D that is connected to both power transformers TW. A second gripping portion 21 that grips an underline (target to be gripped) d, a wire (connecting linear member) W that connects both the first and second gripping portions 11 and 21 and maintains a connected state, and the wire W The adjustment part 31 which adjusts the separation space between the 1st, 2nd holding parts 11 and 21 by adjusting length by winding is comprised.

ここで、両電源変圧器ＴＷは、電柱ＵＰの腕金ＡＭに引き留めて架線する送電線Ｄの間に設置する自動開閉器ＣＢなどの制御用電源としてその腕金ＡＭに取り付けられており、この両電源変圧器ＴＷは、自動開閉器ＣＢの上流側と下流側の送電線Ｄのそれぞれに分岐接続する高圧引下線ｄを接続されて、その上流側と下流側の送電線Ｄのいずれからも駆動用電力を受電できるようになっている。このため、両電源変圧器ＴＷは、交換するために高圧引下線ｄを切断したときには、停電させない限り、切断箇所に高電圧が露出する充電箇所となる。   Here, the dual power transformer TW is attached to the arm metal AM as a control power source for an automatic switch CB or the like installed between the power transmission lines D that are retained by the arm metal AM of the utility pole UP. The double power transformer TW is connected to a high-voltage underline d that is branched and connected to each of the upstream and downstream transmission lines D of the automatic switch CB, and from both the upstream and downstream transmission lines D. The drive power can be received. For this reason, when the high-voltage underline d is disconnected for replacement, the dual power transformer TW becomes a charging point where a high voltage is exposed at the cutting point unless a power failure occurs.

そして、第１把持部１１は、図２に示すように、雌ネジ１２ａが形成されている基底部１２と、この基底部１２から連続する上下反転したＪ字形状部１３と、基底部１２の雌ネジ１２ａに噛み合って回転することにより頭部側をＪ字形状部１３の湾曲形状部（受け部材）１３ａに向かって進退させる雄ネジ（ネジ構造）１４と、この雄ネジ１４の頭部に相対回転自在に連結されている押付部材１５と、雄ネジ１４の頭部の反対側に相対回転不能に固定されて後述の図４に示す絶縁操作棒（棒状操作道具）１００の先端部を着脱自在に連結するジョイント操作部（着脱部材）１６と、を備えて構築されている。
この構成により、第１把持部１１は、Ｊ字形状部１３の湾曲形状部１３ａを送電線Ｄに回転不能に引っ掛けることができ、このＪ字形状部１３と一体の基底部１２に対してジョイント部１６を介して雄ネジ１４を順回転させることにより、頭部の押付部材１５をＪ字形状部１３の縦板部１３ｂに回転しないように案内させつつ湾曲形状部１３ａに接近させて押し付けることで送電線Ｄを間に挟んで把持することができ、反対に逆回転させることで押付部材１５を離隔させて送電線Ｄから外すことができる。
ここで、押付部材１５は、送電線Ｄの押し付け面にゴム板１５ｒが固定されており、挟み込む送電線Ｄがずれてしまうことを制限して、安定して把持する状態を維持することができるようになっている。 As shown in FIG. 2, the first grip portion 11 includes a base portion 12 in which a female screw 12 a is formed, a J-shaped portion 13 that is vertically inverted from the base portion 12, and a base portion 12. A male screw (screw structure) 14 that moves the head side toward the curved shape portion (receiving member) 13a of the J-shaped portion 13 by meshing with the female screw 12a and rotating, and a head of the male screw 14 A pressing member 15 connected in a relatively rotatable manner and a distal end portion of an insulating operating rod (bar-shaped operating tool) 100 shown in FIG. And a joint operation section (detachable member) 16 that is freely connected.
With this configuration, the first gripping portion 11 can hook the curved shape portion 13a of the J-shaped portion 13 on the power transmission line D in a non-rotatable manner, and is jointed to the base portion 12 integral with the J-shaped portion 13. By pushing the male screw 14 forward through the portion 16, the pressing member 15 at the head is guided to the vertical plate portion 13b of the J-shaped portion 13 so as not to rotate, and is pressed close to the curved shape portion 13a. Thus, the power transmission line D can be held between them, and the pressing member 15 can be separated from the power transmission line D by rotating in the reverse direction.
Here, the pressing member 15 has a rubber plate 15r fixed to the pressing surface of the power transmission line D, and can limit the displacement of the power transmission line D to be sandwiched and maintain a stable gripping state. It is like that.

第２把持部２１は、図３に示すように、高圧引下線ｄの外周面に沿う内周面を有する円筒形状を二つ割りして圧接させる一対の圧接部２２と、この圧接部２２の一端辺２２ａ側を開閉可能に他端辺２２ｂ側を相対回転自在に連結するヒンジ部２３と、ヒンジ部２３の両側の他端辺２２ｂ側外周面にリブ形状に一体形成されて互いに接近することにより圧接部２２の一端辺２２ａを開口させる一対のツマミ部２４と、このツマミ部２４の間に圧縮状態で設置されて離隔方向に付勢するスプリング２５と、を備えるクリップ構造に構築されている。
この構成により、第２把持部２１は、ツマミ部２４を摘んでスプリング２５の付勢力に抗して接近させることにより、圧接部２２の一端辺２２ａを開口させて高圧引下線ｄを内部に位置させることができ、その摘み力を緩めてツマミ部２４をスプリング２５の付勢力で離隔させることにより、圧接部２２の一端辺２２ａ間を閉めて高圧引下線ｄを挟む状態で把持することができ、再度、ツマミ部２４を摘むことで圧接部２２の一端辺２２ａを開口させて高圧引下線ｄから外すことができる。
ここで、圧接部２２は、高圧引下線ｄに圧接させる内面にゴム板２２ｒが固定されており、挟み込む高圧引下線ｄの延長方向や外れる方向にずれてしまうことを制限して、安定して把持する状態を維持できるようになっている。また、ヒンジ部２３の一端側に不図示の連結孔の開口する連結部２６が一体形成されており、その連結孔にワイヤＷを通して連結部２６に連結できるようになっている。 As shown in FIG. 3, the second gripping portion 21 includes a pair of pressure contact portions 22 that are split into two cylindrical shapes having an inner peripheral surface along the outer peripheral surface of the high-pressure underline d, and one end side of the pressure contact portion 22. The hinge part 23 which connects the other end side 22b side so that relative rotation is possible so that the 22a side can be opened and closed, and the outer peripheral surface of the other end side 22b side on both sides of the hinge part 23 are integrally formed in a rib shape and brought into close contact with each other It is constructed in a clip structure comprising a pair of knob parts 24 that open one end side 22a of the part 22 and a spring 25 that is placed between the knob parts 24 in a compressed state and biases in the separation direction.
With this configuration, the second gripping portion 21 picks up the knob portion 24 and approaches it against the urging force of the spring 25, thereby opening one end side 22a of the press-contact portion 22 and positioning the high-pressure underline d inside. By loosening the gripping force and separating the knob portion 24 by the urging force of the spring 25, the one end side 22a of the press contact portion 22 can be closed and the high pressure underline d can be sandwiched. By once again picking the knob portion 24, the one end side 22a of the press contact portion 22 can be opened and removed from the high pressure underline d.
Here, the pressure contact portion 22 has a rubber plate 22r fixed to the inner surface to be brought into pressure contact with the high-pressure underline d, and restricts the displacement of the high-pressure underline d to be sandwiched between the extension direction and the direction of disengagement. The gripping state can be maintained. Further, a connecting portion 26 having a connecting hole (not shown) is integrally formed on one end side of the hinge portion 23, and can be connected to the connecting portion 26 through a wire W in the connecting hole.

調整部３１は、図２に戻って、ワイヤＷを巻き付ける巻棒（巻取機構）３２と、この巻棒３２の上下両端部を回転自在に支持する支持部３３と、切換レバー３４ａの倒す向きを変えることで巻棒３２の許容回転方向を切り換えることにより機能させる回転方向、すなわち、許容するワイヤＷの巻付または引出を選択する支持部３３内に内蔵のラチェット機構３４と、支持部３３を貫通する巻棒３２の基端部に相対回転不能に固定されて絶縁操作棒１００の先端部を着脱自在に連結するジョイント操作部（着脱部材）３６と、を備えて構築されている。
この構成により、調整部３１は、切換レバー３４ａの切換操作後にジョイント部３６を介して巻棒３２を順回転させることによりワイヤＷを巻き取って引出長さを短くし、反対に逆回転させたり、引っ張ることを許容してワイヤＷの引出長さを長くすることができる。 Returning to FIG. 2, the adjusting unit 31 returns a winding rod (winding mechanism) 32 around which the wire W is wound, a support unit 33 that rotatably supports both upper and lower ends of the winding rod 32, and a direction in which the switching lever 34 a is tilted. By changing the allowable rotation direction of the winding rod 32 by changing the rotation direction, that is, the ratchet mechanism 34 built in the support portion 33 that selects the winding or drawing of the wire W to be allowed and the support portion 33 are provided. A joint operating portion (detachable member) 36 is fixed to the base end portion of the winding rod 32 penetrating the shaft and is fixed so as not to rotate relative to the distal end portion of the insulating operating rod 100 so as to be detachable.
With this configuration, the adjustment unit 31 winds the wire W by rotating the winding rod 32 forward via the joint portion 36 after the switching operation of the switching lever 34a, shortens the drawing length, and reversely rotates the winding rod 32. The pulling-out length of the wire W can be increased by allowing the pulling.

この調整部３１は、支持部３３が第１把持部１１のＪ字形状部１３の縦板部１３ｂの背面側に固定されており、引き出したワイヤＷの先端側に第２把持部２１の連結部２６が連結されている。
この構成により、連結保持具１０は、調整部３１でワイヤＷの引出長さを調整することにより、第１、第２把持部１１、２１の離隔する連結間隔を調整することができる。 In the adjusting portion 31, the support portion 33 is fixed to the back side of the vertical plate portion 13 b of the J-shaped portion 13 of the first gripping portion 11, and the second gripping portion 21 is connected to the leading end side of the drawn wire W. The part 26 is connected.
With this configuration, the connection holder 10 can adjust the distance between the first and second gripping portions 11 and 21 by adjusting the pull-out length of the wire W with the adjustment portion 31.

この第１把持部１１および調整部３１のジョイント部１６、３６は、絶縁操作棒１００の先端部を差込可能に円筒形状に形成されており、円筒形状の対面する周面のそれぞれが概略Ｔ字形状に切り欠かれて開口することにより後端面（絶縁操作棒１００）側から先端側に向う差込切欠部４６と、この差込切欠部４６の直交方向の両側に連続するように屈曲する係合切欠部４７と、が一対形成されている。   The joint portions 16 and 36 of the first gripping portion 11 and the adjusting portion 31 are formed in a cylindrical shape so that the distal end portion of the insulating operation rod 100 can be inserted, and each of the circumferential surfaces facing the cylindrical shape is approximately T. By being cut and opened in a letter shape, the insertion notch 46 is directed from the rear end face (insulating operation rod 100) side to the front end side, and the insertion notch 46 is bent continuously on both sides in the orthogonal direction. A pair of engagement notches 47 is formed.

これに対して、絶縁操作棒１００は、図４に示すように、円柱形状の先端部の互いに反対側となる側面に突起形状に一対立設されることによりジョイント部１６、３６の２箇所の切欠部４６、４７内に挿し込んで係合させることのできるピン１０１と、先端部の先端面に配設されて不図示の内蔵スプリングにより突出方向に付勢されている突起１０２と、先端部の側面に刻設されている不図示のネジ形状に螺合して進退可能なグリップ１０３と、滑り難い材質の取替え可能な滑り止が施されて作業員の把持する基端部側の把持部１０４と、を備えている。
この構成により、第１把持部１１と調整部３１は、ジョイント部１６、３６内に絶縁操作棒１００の先端部を差し込んで突起１０２を内蔵スプリングの弾性力に抗して沈ませつつ、ピン１０１の双方を切欠部４６、４７内に進入させて回転させた後に、その進入させる力を解放すると、突起１０２がスプリングの弾性力により突出してジョイント部１６、３６を押し出すことにより、その係合切欠部４７から屈曲する係合溝４７ａ内にピン１０１を離脱不能に係合させることができ、その絶縁操作棒１００を回転させることで送電線Ｄへの取付（把持）操作や取外操作を遠隔位置からすることができる。この絶縁操作棒１００は、逆操作することで第１把持部１１や調整部３１のジョイント部１６、３６から外した状態にして両電源変圧器ＴＷの交換作業を行なってもよく、あるいは、グリップ１０３を回転させてジョイント部１６、３６側に寄せることによりピン１０１が係合溝４７ａ内から離脱して回転しないようにロックした状態にして両電源変圧器ＴＷの交換作業をしてもよい。
