Description

活線振分工具用の電線保持具及び活線振分方法Wire holder for live-line distribution tool and live-line distribution method
　本発明は、電線の架設・保守の無停電工事における活線振分作業に用いられる活線振分工具用の電線保持具及び活線振分方法に関するものである。 The present invention relates to an electric wire holder for a live-line distribution tool and a live-line distribution method used for live-line distribution work in non-power failure work for erection and maintenance of electric wires.
　無停電工事における電線の切断作業では、切断した電線の端部同士が互いに触れないように活線振分工具が用いられる。活線振分工具の多くは、電線を掴む掴線器と、掴んだ電線を引き寄せる張線器と、引き寄せられて撓んだり、切断されて不安定になった電線を保持する電線保持具を備えている。 In the uninterruptible power cutting work, a live-line distribution tool is used so that the ends of the cut wires do not touch each other. Most live-line distribution tools have a wire gripper that grabs the wire, a wire tensioner that pulls the grabbed wire, and a wire holder that holds the wire that is pulled and bent or cut and becomes unstable. I have.
　図９は、従来の活線振分工具１００を示す図である。活線振分工具１００は、電線２００の切断が必要な箇所を２つの掴線器１０２の間に含まれるようにして配置される。そして２つの掴線器１０２が連結されている張線器１０１を収縮させることにより、電線２００に撓みが形成される。撓んだ状態で電線２００が切断され、切断端部同士が互いに触れないように、２つの電線保持具１０３によって離隔状態に置かれる。 FIG. 9 is a diagram showing a conventional live-line distribution tool 100. The live-line distribution tool 100 is arranged so that a portion of the electric wire 200 that needs to be cut is included between the two wire gripping devices 102. Then, by contracting the wire tensioning device 101 to which the two wire gripping devices 102 are connected, the electric wire 200 is bent. The electric wire 200 is cut in a bent state, and is placed in a separated state by two electric wire holders 103 so that the cut ends do not touch each other.
　このように活線振分工具１００を用いることにより、無停電工事において通電事故を防止し、安全に作業を行うことが可能となる。 By using the live-line distribution tool 100 in this way, it is possible to prevent an energization accident in uninterruptible work and perform work safely.
　このような活線振分工具については、特許文献１に記載がある。 Patent Document 1 describes such a live-line distribution tool.
特開２００８－２０６２５４号公報Japanese Unexamined Patent Publication No. 2008-206254
　図９のような活線振分工具１００を用いる場合、切り分けられた電線２００の端部は、風に揺られたり不安定な状態で保持されていると、周辺装置や作業者に接触する恐れがある。そのため、できるだけ切断端に近い位置で電線２００を保持することが望ましい。 When the live-line distribution tool 100 as shown in FIG. 9 is used, if the cut end of the electric wire 200 is shaken by the wind or held in an unstable state, it may come into contact with peripheral devices or an operator. There is. Therefore, it is desirable to hold the electric wire 200 at a position as close to the cut end as possible.
　また、電線保持具１０３の構成において電線２００を収容する空間が電線２００の径に対して広すぎると、保持されている電線２００の自由度が大きくなり過ぎるので、できるだけ電線２００の径に近い必要最小限の空間に形成された保持枠で保持することが望ましい。 Further, in the configuration of the electric wire holder 103, if the space for accommodating the electric wire 200 is too wide with respect to the diameter of the electric wire 200, the degree of freedom of the held electric wire 200 becomes too large, so that the diameter of the electric wire 200 needs to be as close as possible. It is desirable to hold it with a holding frame formed in the minimum space.
　一方、切断された電線２００を接続する際に、切断箇所を修復するためにスリーブカバーが利用されることが多い。そして切断された電線２００は端部から一定の長さで被覆が剥ぎ取られている。したがって、スリーブカバーは、少なくとも、被覆の剥ぎ取られた領域を覆うことができる長さが必要となる。 On the other hand, when connecting the cut electric wire 200, a sleeve cover is often used to repair the cut portion. The cut wire 200 is stripped of its coating from the end to a certain length. Therefore, the sleeve cover needs to be at least long enough to cover the stripped area of the coating.
　ところで、スリーブカバーを被せる前に電線２００の接続が完了した状態になっていなければならないので、接続前に予め何れか一方の電線２００をスリーブカバーに通しておき、接続後、スリーブカバーを接続箇所の上にスライドさせるという工程が必要になる。 By the way, since the connection of the electric wire 200 must be completed before the sleeve cover is put on, one of the electric wires 200 must be passed through the sleeve cover in advance before the connection, and after the connection, the sleeve cover is connected to the connection point. The process of sliding it on is required.
　ここで、このような工程をスムーズに進めるためには、スリーブカバーと電線保持具１０３とが干渉しないように注意する必要がある。しかし、上述のように電線保持具１０３の電線収容空間を電線２００の径に近い大きさに設定しておくと、スリーブカバーが干渉してしまう。また、これを回避するために、スリーブカバーが干渉しない位置まで電線保持具１０３を離隔させて配置すると、２つの電線保持具１０３同士が離れすぎるので、電線２００の切断端が大きく垂れ下がり、安定しない。 Here, in order to proceed smoothly with such a process, it is necessary to be careful not to interfere with the sleeve cover and the wire holder 103. However, if the wire accommodating space of the wire holder 103 is set to a size close to the diameter of the wire 200 as described above, the sleeve cover interferes. Further, in order to avoid this, if the wire holder 103 is arranged so as to be separated from each other to a position where the sleeve cover does not interfere with each other, the two wire holders 103 are too far apart from each other, so that the cut end of the wire 200 hangs down significantly and is not stable. ..
　そこで、本発明では、スリーブカバーとの干渉を防止し、且つ、切り分けた電線同士の安全な離隔距離を確保する活線振分工具用の電線保持具を提供することを目的とする。 Therefore, an object of the present invention is to provide an electric wire holder for a live wire distribution tool that prevents interference with the sleeve cover and secures a safe separation distance between the separated electric wires.
　上記目的を達成するために、本発明の活線振分工具用の電線保持具は、両端に掴線器を配した張線器に対して旋回可能に取り付けられている活線振分工具の電線保持具であって、一部に形成された開口から電線を収容して保持する保持枠と、前記保持枠内で大きさの異なる少なくとも２つの区画を形成するように、連通口を一部に残して領域を隔てる隔壁部と、前記張線器を挟持して固定する挟持固定部とを備えたことを特徴とする。 In order to achieve the above object, the electric wire holder for the live-line distribution tool of the present invention is a hot-line distribution tool that is rotatably attached to a wire tensioning device having grips at both ends. A part of the communication port that is an electric wire holder so as to form a holding frame for accommodating and holding the electric wire from a partially formed opening and at least two sections having different sizes within the holding frame. It is characterized by having a partition wall portion that separates the area by leaving it in the center, and a holding and fixing portion that sandwiches and fixes the wire tensioning device.
　また、本発明の活線振分工具用の電線保持具は、上記構成に加えて、前記２つの区画のうち大きい側が小さい側よりも前記挟持固定部に近い位置に形成されていることを特徴とする。 Further, the electric wire holder for the hot-line distribution tool of the present invention is characterized in that, in addition to the above configuration, the large side of the two sections is formed at a position closer to the holding and fixing portion than the smaller side. And.
　また、本発明の活線振分工具用の電線保持具は、上記構成に加えて、前記開口は、前記２つの区画のうち前記挟持固定部に近い側に形成されていることを特徴とする。 Further, the electric wire holder for the hot-line distribution tool of the present invention is characterized in that, in addition to the above configuration, the opening is formed on the side of the two compartments closer to the sandwiching and fixing portion. ..
　また、本発明の活線振分工具用の電線保持具は、上記構成に加えて、前記挟持固定部によって前記張線器と共に挟持固定され、前記保持枠の旋回操作を行う把持部を備えたことを特徴とする。 Further, in addition to the above configuration, the electric wire holder for the hot-line distribution tool of the present invention is provided with a grip portion which is pinched and fixed together with the wire tensioning device by the pinching fixing portion to perform a turning operation of the holding frame. It is characterized by that.
　また、本発明の活線振分工具用の電線保持具は、上記構成に加えて、前記把持部は、前記張線器に沿って設けられる当板部と、前記当板部を介して前記張線器とは反対側に設けられ、振り分け操作を行うためのハンドルとを備えたことを特徴とする。 Further, in the electric wire holder for the hot-line distribution tool of the present invention, in addition to the above configuration, the grip portion is the plate portion provided along the wire tensioning device and the plate portion via the plate portion. It is provided on the opposite side of the wire tensioner and is characterized by having a handle for performing a sorting operation.
　また、本発明の活線振分方法は、張線器と、前記張線器の両端に配置される２つの掴線器と、前記張線器に取り付けられてスリーブカバーが通過可能な第１区画及び電線のみを保持するための第２区画を有する電線保持具を用いた活線振分方法であって、掴持した前記電線を前記２つの掴線器の間で切断する工程と、切断された前記電線の一方の端部に装着した前記スリーブカバーを、前記端部から前記第１区画を通過するまで押し込む工程と、前記スリーブカバーを装着した側の前記電線を前記第２区画へ移す工程と、切断された前記電線の前記端部同士を振り分ける工程とを含むことを特徴とする。 Further, in the live wire distribution method of the present invention, a wire tensioning device, two wire gripping devices arranged at both ends of the wire tensioning device, and a first method attached to the wire tensioning device through which the sleeve cover can pass. It is a live wire distribution method using a wire holder having a second section for holding only a section and an electric wire, and is a step of cutting the held electric wire between the two gripping devices and cutting. The step of pushing the sleeve cover attached to one end of the electric wire from the end until it passes through the first section, and moving the electric wire on the side to which the sleeve cover is attached to the second section. It is characterized by including a step and a step of distributing the ends of the cut electric wire to each other.
　また、本発明の活線振分方法は、上記工程に加えて、振り分けられた位置から元の位置に戻された前記電線のうち、前記スリーブカバーが装着された側の前記電線を前記第２区画から前記第１区画へ移動させる工程と、前記スリーブカバーを、前記第１区画で通過させて前記端部側へ戻す工程と、切断された前記電線同士を接続し、戻した前記スリーブカバーで接続箇所を覆う工程とを含むことを特徴とする。 Further, in the live-line distribution method of the present invention, in addition to the above steps, among the electric wires returned from the distributed position to the original position, the electric wire on the side to which the sleeve cover is attached is the second. The step of moving from the section to the first section, the step of passing the sleeve cover in the first section and returning it to the end side, and the step of connecting the cut electric wires to each other and returning the sleeve cover. It is characterized by including a step of covering a connection portion.
　以上のように、本発明の活線振分工具用の電線保持具によれば、電線を収容して保持する保持枠の内側には、連通口を一部に残すようにして大きさの異なる少なくとも２つの区画に隔てられる。これにより開口から収容された電線は、連通口を通過させることにより、保持枠の中で自在に位置を変えることができる。したがって、比較的電線の硬度が高く、振り分けが容易ではない電線については、挟持固定部に近い側の区画に配置された状態で振り分けを行うことができる。また、振り分けが容易である電線や、電圧が高いため大きく振り分けることが必要な電線は、挟持固定部から遠い側に位置する区画に収容した状態で振り分けを行うことができる。このように、対象となる電線に応じて振り分け間隔を自在に選択することが可能となる。 As described above, according to the electric wire holder for the hot-line distribution tool of the present invention, the size is different so that the communication port is partially left inside the holding frame for accommodating and holding the electric wire. It is separated into at least two compartments. As a result, the electric wire accommodated from the opening can be freely changed in position in the holding frame by passing through the communication port. Therefore, for an electric wire having a relatively high hardness and not easy to be sorted, it is possible to sort the electric wire in a state of being arranged in a section near the holding and fixing portion. Further, the electric wire that can be easily distributed and the electric wire that needs to be largely distributed due to the high voltage can be distributed in a state of being housed in a section located on the side far from the pinching fixing portion. In this way, it is possible to freely select the distribution interval according to the target electric wire.
　また、本発明の活線振分工具用の電線保持具によれば、上記効果に加えて、大きさが異なる２つの区画のうち、大きい側が挟持固定部に近い側に形成されているので、電線の直径や被覆厚が大きく、振り分けが容易ではない電線は、挟持固定部に近い側に収容することができる。 Further, according to the electric wire holder for the hot-line distribution tool of the present invention, in addition to the above effect, the larger side of the two sections having different sizes is formed on the side closer to the pinching fixing portion. An electric wire having a large diameter and a large coating thickness and which is not easy to sort can be accommodated on the side close to the holding and fixing portion.
　また、本発明の活線振分工具用の電線保持具によれば、上記効果に加えて、開口が２つの区画のうち、挟持固定部に近い側に形成されているので、電線の種類に関わらず、保持枠内に収容する際に、挟持固定部（張線器）から大きく引き離すことなく容易に収容することが可能となる。 Further, according to the electric wire holder for the hot-line distribution tool of the present invention, in addition to the above effect, the opening is formed in the side of the two compartments closer to the pinching and fixing portion, so that the type of electric wire can be selected. Nevertheless, when it is accommodated in the holding frame, it can be easily accommodated without being largely separated from the pinching fixing portion (tensioner).
　また、本発明の活線振分工具用の電線保持具によれば、上記効果に加えて、保持枠の旋回操作を行うための把持部が、挟持固定部によって張線器と共に挟持固定されるので、張線器に対する保持枠の固定と、保持枠に対する把持部の固定が一つの固定部（挟持機構）により固定できる。これにより、構造が簡易的になるので部品点数とともに、重量の増大を抑えることが可能となる。 Further, according to the electric wire holder for the hot-line distribution tool of the present invention, in addition to the above effect, the grip portion for performing the turning operation of the holding frame is pinched and fixed together with the wire tensioning device by the pinching fixing portion. Therefore, the holding frame can be fixed to the wire tensioner and the grip portion can be fixed to the holding frame by one fixing portion (pinching mechanism). As a result, the structure is simplified, so that it is possible to suppress an increase in weight as well as the number of parts.
　また、本発明の活線振分工具用の電線保持具によれば、上記効果に加えて、把持部には、張線器に沿って当板部が設けられているので、旋回操作において把持部が挟持固定部内で傾斜した場合であっても、当板部が張線器に当接することにより、必要以上に姿勢が崩れることを防止できる。これにより、張線器に対する保持枠の固定と、保持枠に対する把持部の固定とを同じ固定部（挟持機構）により固定する構成であっても、挟持圧力の差異によって把持部側の固定に弛みが生じた場合でも安定して挟持状態を維持することができる。 Further, according to the electric wire holder for the hot-line distribution tool of the present invention, in addition to the above effect, the grip portion is provided with a plate portion along the wire tensioning device, so that the grip portion is gripped in a turning operation. Even when the portion is tilted in the sandwiching and fixing portion, it is possible to prevent the posture from being unnecessarily collapsed by the contact of the plate portion with the wire tensioning device. As a result, even if the holding frame is fixed to the wire tensioner and the grip portion is fixed to the holding frame by the same fixing portion (pinching mechanism), the grip portion side is slackened due to the difference in the pinching pressure. Can be stably maintained in the pinched state even when the above occurs.
　また、本発明の活線振分方法によれば、大きさの異なる第１及び第２区画を内部に有する電線保持具を用いて電線を保持するので、電線に対して径が大きいスリーブカバーを扱う場合には、大きい側の第１区画に電線を配置し、スリーブカバーが通過した後の電線を大きく振り分ける場合には、小さい側の第２区画に電線を配置するといった使い分けが可能となる。これにより、振り分けられる電線に対しては、不要に広い空間に収容されることがないので、振り分け状態が安定する。 Further, according to the live wire distribution method of the present invention, since the electric wire is held by using the electric wire holder having the first and second compartments having different sizes inside, a sleeve cover having a large diameter with respect to the electric wire can be used. When handling, the electric wire is arranged in the first section on the large side, and when the electric wire after the sleeve cover has passed is largely distributed, the electric wire can be arranged in the second section on the small side. As a result, the distributed electric wires are not unnecessarily accommodated in a wide space, so that the distributed state is stable.
　また、本発明の活線振分方法によれば、上記効果に加えて、振り分け状態から元の状態に戻し、電線が接続された箇所にスリーブカバーを戻す際にも、大きさの異なる２つの第１及び第２区画を自在に使い分けて、電線保持具とスリーブカバーとの干渉を防止することができる。これにより、作業効率及び安全性が向上する。 Further, according to the live-line distribution method of the present invention, in addition to the above effects, when returning from the distribution state to the original state and returning the sleeve cover to the place where the electric wire is connected, two different sizes are used. The first and second compartments can be freely used to prevent interference between the wire holder and the sleeve cover. This improves work efficiency and safety.

　＜電線保持具＞
　図１は、本発明の実施の形態に係る活線振分工具用の電線保持具１の全体斜視図である。電線保持具１は、一部に開口２ａが形成された保持枠２と、この保持枠２を張線器に固定する挟持固定部８と、保持枠２の旋回操作を行うための把持部１０とを備えている。 <Wire holder>
FIG. 1 is an overall perspective view of an electric wire holder 1 for a hot-line distribution tool according to an embodiment of the present invention. The electric wire holder 1 includes a holding frame 2 having an opening 2a partially formed, a holding fixing portion 8 for fixing the holding frame 2 to a wire tensioner, and a gripping portion 10 for performing a turning operation of the holding frame 2. And have.
　保持枠２では、内側の電線収容領域が２つの区画２ｂ、２ｃに分けられている。これら２つの区画２ｂ、２ｃは大きさが異なっており、挟持固定部８に近い側の区画２ｂ（第１区画）の方が大きく、遠い側の区画２ｃ（第２区画）は比較的小さい。本実施の形態に係る構成では、保持枠２を張線器に固定する挟持固定部８から離れる方向に、これら２つの区画２ｂ、２ｃが並ぶように構成されている。 In the holding frame 2, the inner wire accommodating area is divided into two sections 2b and 2c. These two compartments 2b and 2c are different in size, the compartment 2b (first compartment) on the side closer to the sandwiching fixing portion 8 is larger, and the compartment 2c (second compartment) on the far side is relatively small. In the configuration according to the present embodiment, these two compartments 2b and 2c are arranged so as to be separated from the holding fixing portion 8 for fixing the holding frame 2 to the wire tensioning device.
　２つの区画２ｂ、２ｃを隔てているのは、隔壁部４である。隔壁部４は保持枠２の内側から延設されており、先端側は上方（小さい区画２ｃ側）へ向けて曲がっている。この隔壁部４は、２つの区画２ｂ、２ｃを完全に分離せず、一部に連通口６を残すように設けられている。この連通口６は、スリーブカバーが装着されていない電線が通過可能である。区画２ｃによって、電線の自由度をある程度抑えて安定的に保持できる空間が形成されている。 It is the partition wall 4 that separates the two compartments 2b and 2c. The partition wall portion 4 extends from the inside of the holding frame 2, and the tip end side is bent upward (small section 2c side). The partition wall portion 4 is provided so as not to completely separate the two compartments 2b and 2c, but to leave a communication port 6 in a part thereof. An electric wire to which the sleeve cover is not attached can pass through the communication port 6. The compartment 2c forms a space in which the degree of freedom of the electric wire is suppressed to some extent and can be stably held.
　２つの区画２ｂ、２ｃのうち、大きい側の区画２ｂに対して開口２ａが形成されている。区画２ｂは、後述するように、スリーブカバーが装着された電線を収容可能な大きさに形成されている。 Of the two compartments 2b and 2c, the opening 2a is formed in the larger compartment 2b. As will be described later, the compartment 2b is formed in a size capable of accommodating an electric wire to which a sleeve cover is attached.
　開口２ａを開閉する開閉具１２には、長手方向に貫通した長孔１２ａが形成されており、この長孔１２ａを貫通してガイドピン１４が保持枠２の外面と螺合している。このように、開閉具１２は、保持枠２の外側面に形成された溝、ガイドピン１４及びガイド板１６を摺動のガイドとしてスライドし、開口２ａを開閉する。保持枠２の開口２ａのうち、開閉具１２の下端が収まる部分には、閉止状態を固定するための閉止ボルト１８が設けられている。ここでは、閉状態の開閉具１２を実線で表し、開状態の開閉具１２を点線で表している。 An elongated hole 12a penetrating in the longitudinal direction is formed in the opening / closing tool 12 that opens and closes the opening 2a, and the guide pin 14 is screwed to the outer surface of the holding frame 2 through the elongated hole 12a. In this way, the opening / closing tool 12 slides the groove, the guide pin 14 and the guide plate 16 formed on the outer surface of the holding frame 2 as a sliding guide to open / close the opening 2a. A closing bolt 18 for fixing the closed state is provided in a portion of the opening 2a of the holding frame 2 where the lower end of the opening / closing tool 12 fits. Here, the open / close tool 12 in the closed state is represented by a solid line, and the open / close tool 12 in the open state is represented by a dotted line.
　なお、図１には、開閉具１２が摺動可能な貫通孔が形成されたガイド板１６を備えた構成を例として示した。しかし、ガイドピン１４を支点として開閉具１２の下方側が揺れることにより位置が定まらない状態を安定させるためには、ガイド板１６の代わりに、フレーム状の部材で囲うだけでも構わない。 Note that FIG. 1 shows an example of a configuration in which the opening / closing tool 12 is provided with a guide plate 16 having a slidable through hole. However, in order to stabilize the state in which the position cannot be determined due to the lower side of the opening / closing tool 12 swinging with the guide pin 14 as the fulcrum, a frame-shaped member may be used instead of the guide plate 16.
　図２は、図１の電線保持具１の把持部１０の周辺を分解した図である。把持部１０は、保持枠２の下方に設けられた挟持固定部８に取り付けられている。具体的には、挟持固定部８を構成する挟持枠８ｃの間に、張線器と共に配置され、アイボルト８ａ及びアイナット８ｂを貫通させて挟持固定される。挟持枠８ｃと把持部１０の当板部１０ａの側面との間に僅かな遊びが設けられており、アイボルト８ａ及びアイナット８ｂを締め付ける力で固定の強度が加減される。このように構成されているので、挟持固定部８は単一の締結構造しか有していないにも関わらず、把持部１０側の挟持固定が張線器側の固定の妨げとなることを防ぎ、張線器側を安定して挟持することができる。 FIG. 2 is an exploded view of the periphery of the grip portion 10 of the electric wire holder 1 of FIG. The grip portion 10 is attached to a pinch fixing portion 8 provided below the holding frame 2. Specifically, it is arranged together with a wire tensioner between the sandwiching frames 8c constituting the sandwiching and fixing portion 8, and is sandwiched and fixed by penetrating the eyebolts 8a and the eyenuts 8b. A slight play is provided between the holding frame 8c and the side surface of the plate portion 10a of the grip portion 10, and the fixing strength is adjusted by the force of tightening the eyebolt 8a and the eye nut 8b. Since it is configured in this way, even though the pinching fixing portion 8 has only a single fastening structure, it is possible to prevent the pinching fixing on the grip portion 10 side from hindering the fixing on the wire tensioning device side. , The wire tensioner side can be stably pinched.
　図３は、図１の電線保持具１の正面図である。上述したように、保持枠２の内側の２つの区画２ｂ及び２ｃが大小関係を有しており、且つ、張線器に固定される挟持固定部８から遠ざかる方向に向けて、近い側に大きい区画２ｂ、遠い側に小さい区画２ｃが設けられているのが見て取れる。図３中には、大きさの比較のため、電線２００及びスリーブカバー２０１を点線で表している。 FIG. 3 is a front view of the electric wire holder 1 of FIG. As described above, the two compartments 2b and 2c inside the holding frame 2 have a magnitude relationship, and are larger toward the closer side in the direction away from the pinching fixing portion 8 fixed to the wire tensioning device. It can be seen that the compartment 2b and the small compartment 2c are provided on the far side. In FIG. 3, the electric wire 200 and the sleeve cover 201 are shown by dotted lines for comparison of sizes.
　小さい区画２ｃは電線２００の径を僅かに大きくした空間として形成されている。これにより、活線振分時に保持枠２を旋回操作する際、安定して電線２００を保持でき、離隔状態も安定する。また、連通口６も小さい区画２ｃと同様に、電線２００の径を僅かに大きくした空間として形成されている。 The small section 2c is formed as a space in which the diameter of the electric wire 200 is slightly increased. As a result, when the holding frame 2 is swiveled during hot-line distribution, the electric wire 200 can be stably held and the separated state is also stable. Further, the communication port 6 is also formed as a space in which the diameter of the electric wire 200 is slightly increased, similarly to the small compartment 2c.
　これに対して、大きい区画２ｂは、スリーブカバー２０１を収容可能な大きさに形成されている。このように構成されているので、後述するように、電線２００にスリーブカバー２０１を装着する際、電線２００を大きい区画２ｂ側に配置しておくと、スリーブカバー２０１が電線保持具１の保持枠２と干渉することなく、スムーズに通過することが可能となる。 On the other hand, the large compartment 2b is formed in a size that can accommodate the sleeve cover 201. Since it is configured in this way, as will be described later, when the sleeve cover 201 is attached to the electric wire 200, if the electric wire 200 is arranged on the large section 2b side, the sleeve cover 201 is the holding frame of the electric wire holder 1. It is possible to pass smoothly without interfering with 2.
　図４は、把持部１０の斜視図である。把持部１０が、挟持固定部８（図２参照）のアイボルト８ａの軸を中心にして僅かに傾斜することが可能であることは、図２を用いて説明した。これに対して、図４に表れているように、把持部１０には、張線器に沿って延びるように当板部１０ａが設けられている。この当板部１０ａが設けられていることにより、把持部１０がアイボルト８ａを中心に傾いた場合であっても、ハンドル１０ｂを把持する把持部１０等が張線器と干渉することを防止できる。 FIG. 4 is a perspective view of the grip portion 10. It has been described with reference to FIG. 2 that the grip portion 10 can be slightly tilted about the axis of the eyebolt 8a of the pinch fixing portion 8 (see FIG. 2). On the other hand, as shown in FIG. 4, the grip portion 10 is provided with a plate portion 10a so as to extend along the wire tensioning device. By providing the contact plate portion 10a, even when the grip portion 10 is tilted about the eyebolt 8a, it is possible to prevent the grip portion 10 or the like that grips the handle 10b from interfering with the wire tensioning device. ..
　すなわち、本実施の形態に係る挟持固定部８（図２参照）のような構成によれば、挟持による圧力が張線器側と把持部１０側に分散される。ここで、振り分け時の電線保持具１の旋回操作や、振り分け後の電線２００の保持状態を安定させるためには、保持枠２を張線器に対して安定させる必要があるので、挟持固定部８では、張線器側の挟持固定を優先的に考慮する必要がある。しかし、把持部１０側の挟持固定に弛みが生じて、ハンドル１０ｂ等が張線器と干渉するようなことがあれば、旋回操作が安定しない。このような理由から、本実施の形態に係る構成では、把持部１０のハンドル１０ｂと張線器との間に当板部１０ａが設けられている。 That is, according to the configuration as in the pinching fixing portion 8 (see FIG. 2) according to the present embodiment, the pressure due to pinching is distributed to the wire tensioning device side and the gripping portion 10. Here, in order to stabilize the turning operation of the electric wire holder 1 at the time of distribution and the holding state of the electric wire 200 after distribution, it is necessary to stabilize the holding frame 2 with respect to the wire tensioning device. In No. 8, it is necessary to give priority to the pinching and fixing on the wire tensioning device side. However, if the gripping portion 10 side is loosened and the handle 10b or the like interferes with the wire tensioning device, the turning operation is not stable. For this reason, in the configuration according to the present embodiment, the plate portion 10a is provided between the handle 10b of the grip portion 10 and the wire tensioning device.
　ところで、張線器側を優先的に挟持するように構成されていると、アイボルト８ａ及びアイナット８ｂによる締結に弛みが生じた場合、その弛みの程度は、先に把持部１０側の動きとして現れる。よって、遠隔位置であっても、旋回操作時のハンドル１０ｂの傾きなどの状態から、張線器側の弛み状態を把握するといった効果も得られる。これにより、振り分け状態の電線２００が落下する事故を未然に防止することができる。なお、このような作用を生じさせるためには、ハンドル１０ｂの延びる方向を、アイボルト８ａの軸方向に対して交差する方向に設定することが望ましい。 By the way, if the wire tensioning device side is configured to be preferentially sandwiched, when the fastening by the eyebolt 8a and the eyenut 8b is loosened, the degree of the loosening first appears as the movement on the gripping portion 10 side. .. Therefore, even at a remote position, it is possible to obtain an effect of grasping the slack state on the wire tensioning device side from the state such as the inclination of the handle 10b at the time of turning operation. As a result, it is possible to prevent an accident in which the electric wire 200 in the distributed state falls. In order to cause such an action, it is desirable to set the extending direction of the handle 10b to a direction intersecting the axial direction of the eyebolt 8a.
　図５は、使用状態の活線振分工具５０の構成を示す斜視図である。本実施の形態に係る電線保持具１が活線振分工具５０の中で用いられる様子が示されている。電線保持部１は、挟持固定部８（図１参照）によって張線器１０１の伸縮棒に対して挟持固定される。挟持の力は、把持具などの遠隔操作工具によって保持枠２を旋回操作できる程度の大きさに調節される。図５では、２つの電線保持具１の一方が１８０度下方へ旋回したときの位置が点線で表わされている。 FIG. 5 is a perspective view showing the configuration of the live-line distribution tool 50 in the used state. It is shown that the electric wire holder 1 according to the present embodiment is used in the live-line distribution tool 50. The electric wire holding portion 1 is sandwiched and fixed to the telescopic rod of the wire tensioning device 101 by the sandwiching and fixing portion 8 (see FIG. 1). The pinching force is adjusted to such a size that the holding frame 2 can be swiveled by a remote control tool such as a gripper. In FIG. 5, the position when one of the two wire holders 1 is swiveled downward by 180 degrees is represented by a dotted line.
　＜活線振分方法＞
　図６は、切断施工における活線振分作業を説明する図である。ここでは、説明の便宜のため、作業対象となる電線２００及びスリーブカバー２０１を点線で模式的に表している。なお、電線保持具１内における電線２００及びスリーブカバー２０１の位置関係について言及する場面では、適宜、図３を合わせて参照するものとする。 <Live-line distribution method>
FIG. 6 is a diagram illustrating live-line distribution work in cutting work. Here, for convenience of explanation, the electric wire 200 and the sleeve cover 201 to be worked are schematically represented by dotted lines. In addition, when referring to the positional relationship between the electric wire 200 and the sleeve cover 201 in the electric wire holder 1, FIG. 3 shall be referred to as appropriate.
　図６（ａ）では、作業対象となる電線２００の切断予定箇所を２つの電線保持具１の間に含むようにして活線振分工具５０が配置される工程を表している。電線２００は、保持枠２の開口２ａから収容され、挟持固定部８に近い区画２ｂに保持されている（図３参照）。 FIG. 6A shows a process in which the live-line distribution tool 50 is arranged so that the planned cutting portion of the electric wire 200 to be worked is included between the two electric wire holders 1. The electric wire 200 is housed through the opening 2a of the holding frame 2 and is held in the section 2b near the holding and fixing portion 8 (see FIG. 3).
　図６（ｂ）は、図６（ａ）の状態から張線器１０１を収縮させて、電線２００に撓み（ディップ）を形成する工程を表している。これにより切断予定箇所の張力は消失し、作業が容易な無負荷の状態となる。この段階で電線２００の被覆が剥ぎ取られる。 FIG. 6 (b) shows a process of contracting the wire tensioning device 101 from the state of FIG. 6 (a) to form a bend (dip) in the electric wire 200. As a result, the tension at the planned cutting location disappears, and the work becomes easy and unloaded. At this stage, the coating of the electric wire 200 is stripped off.
　図６（ｃ）は、図６（ｂ）の状態から電線２００が切断される際の工程を示している。図中のＸ印は、電線２００が切断された箇所を表している。 FIG. 6 (c) shows a process when the electric wire 200 is cut from the state of FIG. 6 (b). The X mark in the figure represents a place where the electric wire 200 is cut.
　図６（ｄ）は、切断された電線２００のうち、一方にスリーブカバー２０１を装着する工程を表している。電線２００は、図６（ａ）で説明したように、保持枠２内の２つの区画２ｂ、２ｃのうち、大きい方の区画２ｂ（第１区画）に収容されているので、スリーブカバー２０１は干渉することなく保持枠２を通過できる。 FIG. 6D shows a process of attaching the sleeve cover 201 to one of the cut electric wires 200. As described with reference to FIG. 6A, the electric wire 200 is housed in the larger section 2b (first section) of the two sections 2b and 2c in the holding frame 2, so that the sleeve cover 201 is provided. It can pass through the holding frame 2 without interfering with each other.
　図６（ｅ）は、保持枠２の２つの区画２ｂ、２ｃのうち、張線器１０１から遠い側の区画２ｃ（第２区画）に電線２００を移動させる工程を表している。図６（ｄ）においてスリーブカバー２０１は、保持枠２を通過しているので、電線２００を連通口６を通して小さい側の区画２ｃに収容することができる。 FIG. 6E shows a process of moving the electric wire 200 to the section 2c (second section) on the side farther from the wire tensioner 101 among the two sections 2b and 2c of the holding frame 2. Since the sleeve cover 201 passes through the holding frame 2 in FIG. 6D, the electric wire 200 can be accommodated in the small section 2c through the communication port 6.
　図６（ｆ）は、２つの電線保持具１の一方を１８０度旋回させることによって電線２００を振り分ける工程を表している。図６（ｅ）において、電線２００は、張線器１０１から遠い側の区画２ｃに移されているので、電線２００同士を大きく離隔させることが可能である。なお、このとき、安全のため、切断された電線２００の端部にはキャップなどが被せられる。 FIG. 6 (f) shows a process of distributing the electric wire 200 by turning one of the two electric wire holders 1 by 180 degrees. In FIG. 6E, since the electric wire 200 is moved to the section 2c on the side far from the wire tensioning device 101, it is possible to greatly separate the electric wires 200 from each other. At this time, for safety, a cap or the like is put on the end of the cut electric wire 200.
　以上のように、本実施の形態に係る構成によれば、スリーブカバー２０１を通過させる際には、干渉を防ぐために大きい側の区画２ｂが利用され、電線２００を振分る際には、離隔を大きく取るために、張線器１０１から大きく離れた小さい側の区画２ｃが利用される。また、この区画２ｃは、電線２００の径を僅かに大きくする程度の空間に形成されているので、活線振り分けのための旋回操作時や、振り分け状態における作業時に、収容された電線２００が暴れることなく、安定して保持される。 As described above, according to the configuration according to the present embodiment, when passing through the sleeve cover 201, the large side section 2b is used to prevent interference, and when the electric wire 200 is distributed, the separation is performed. In order to take a large amount of space, a small section 2c far away from the wire tensioner 101 is used. Further, since this section 2c is formed in a space such that the diameter of the electric wire 200 is slightly increased, the accommodated electric wire 200 is violent during a turning operation for live-line distribution or during work in the distribution state. It is held stably without any problems.
　図７は、接続施工における活線振分作業を説明する図である。ここでも、図６の場合と同様に、説明の便宜のため、作業対象となる電線２００及びスリーブカバー２０１を点線により模式的に表している。また、適宜、図３を合わせて参照するのも同様である。 FIG. 7 is a diagram illustrating live-line distribution work in connection construction. Here, as in the case of FIG. 6, for convenience of explanation, the electric wire 200 and the sleeve cover 201 to be worked are schematically represented by dotted lines. It is also the same with reference to FIG. 3 as appropriate.
　図７（ａ）は、切断された電線２００が振り分けられた状態を示している。このとき、一方の電線２００には、スリーブカバー２０１が装着されている。 FIG. 7A shows a state in which the cut electric wire 200 is distributed. At this time, a sleeve cover 201 is attached to one of the electric wires 200.
　図７（ｂ）は、振り分けられていた電線２００を元の位置に戻す工程を表している。上述したように、振り分け状態において、電線２００は小さい側の区画２ｃ（第２区画）に収容されているので、旋回時に暴れることなく安全に元の位置に戻すことができる。 FIG. 7B shows the process of returning the distributed electric wire 200 to the original position. As described above, in the distribution state, the electric wire 200 is housed in the small side section 2c (second section), so that the electric wire 200 can be safely returned to the original position without violence during turning.
　図７（ｃ）は、保持枠２の区画２ｃに収容されている電線２００を、大きい側の区画２ｂ（第１区画）へ移動させる工程を表している。この工程により、後に修復される切断位置まで移動させるスリーブカバー２０１と電線保持具１の保持枠２との干渉を防止できる状態になる。 FIG. 7C shows a process of moving the electric wire 200 housed in the section 2c of the holding frame 2 to the section 2b (first section) on the larger side. By this step, the sleeve cover 201 that is moved to the cutting position to be repaired later and the holding frame 2 of the electric wire holder 1 can be prevented from interfering with each other.
　図７（ｄ）は、大きい側の区画２ｂを通過してスリーブカバー２０１が切断箇所を覆う位置に戻される工程を表している。このようにスリーブカバー２０１が戻される前に、保護のために電線２００の端部に装着されていたキャップが外され、互いに接続される。 FIG. 7D represents a process in which the sleeve cover 201 is returned to a position where it passes through the large section 2b and covers the cut portion. Before the sleeve cover 201 is returned in this way, the cap attached to the end of the electric wire 200 for protection is removed and connected to each other.
　以上のように、切断された箇所を接続する工程においても、スリーブカバー２０１を通過させる保持枠２内の区画を干渉の生じない側に変更することができるので、作業効率が向上する。これらの保持枠２内の区画２ｂ、２ｃ間の移動については、保持枠２の外に電線２００を出すことなく作業を行うことができるので、図６の切断作業と同様に、切断された電線２００の落下などの事故の防止により安全性の向上が図られる。 As described above, even in the process of connecting the cut portions, the section in the holding frame 2 through which the sleeve cover 201 is passed can be changed to the side where interference does not occur, so that the work efficiency is improved. As for the movement between the compartments 2b and 2c in the holding frame 2, the work can be performed without extending the electric wire 200 out of the holding frame 2, so that the cut electric wire is the same as the cutting work of FIG. Safety can be improved by preventing accidents such as the fall of 200.
　＜変形例＞
　図８は、図１の電線保持具１の変形例を示す図である。ここでは、図１の電線保持具１と同一の構成については、同一の符号を付して示すこととする。 <Modification example>
FIG. 8 is a diagram showing a modified example of the electric wire holder 1 of FIG. Here, the same configuration as that of the electric wire holder 1 of FIG. 1 is designated with the same reference numerals.
　図８（ａ）は、変形例の電線保持具３１を示している。電線保持具３１の保持枠３２は、開口２ａ側から隔壁部３４が延設されている。隔壁部３４の大きさや形状は、向きは異なるものの、図１の電線保持具１の隔壁部４と略同じである。連通口３６の幅は電線保持具１の連通口６と同程度である。 FIG. 8A shows a modified example of the electric wire holder 31. The holding frame 32 of the electric wire holder 31 has a partition wall portion 34 extending from the opening 2a side. The size and shape of the partition wall portion 34 are substantially the same as the partition wall portion 4 of the electric wire holder 1 of FIG. 1, although the orientation is different. The width of the communication port 36 is about the same as that of the communication port 6 of the electric wire holder 1.
　図８（ｂ）は、変形例の電線保持具４１を示している。電線保持具４１の保持枠４２は、開口２ａ側から離れた位置から隔壁部４４が延設されているのは、図１の電線保持具１と同様であるが、電線保持具１の隔壁部４のように先端が曲がっていない点において異なっている。連通口４６の幅は電線保持具１の連通口６と同程度である。 FIG. 8B shows a modified example of the electric wire holder 41. The holding frame 42 of the electric wire holder 41 has a partition wall portion 44 extending from a position away from the opening 2a side, which is the same as the electric wire holder 1 of FIG. 1, but the partition wall portion of the electric wire holder 1 It differs in that the tip is not bent as in 4. The width of the communication port 46 is about the same as that of the communication port 6 of the electric wire holder 1.
　図８（ｃ）は、変形例の電線保持具５１を示している。電線保持具５１の保持枠５２は、開口２ａ側と、開口２ａから離れた側の両側から隔壁部５４が延設されている。隔壁部５４の先端は、図８（ｂ）の電線保持具４１の隔壁部４４と同じように、直線的である。連通口５６の幅は電線保持具１の連通口６と同程度である。 FIG. 8C shows a modified example of the electric wire holder 51. The holding frame 52 of the electric wire holder 51 has partition walls 54 extending from both sides of the opening 2a side and the side away from the opening 2a. The tip of the partition wall portion 54 is linear like the partition wall portion 44 of the electric wire holder 41 in FIG. 8 (b). The width of the communication port 56 is about the same as that of the communication port 6 of the electric wire holder 1.
　以上に述べてきたような構成は本発明の一例であり、以下のような変形例も含まれる。 The configuration as described above is an example of the present invention, and includes the following modified examples.
　（１）上記の実施の形態では、電線保持具１、３１、４１、５１の保持枠２、３２、４２、５２内は、大きさの異なる２つの区画２ｂ、２ｃに隔てられている構成を例として示した。しかし、少なくとも、大小関係を有する２つの区画を含んでいれば、３つ以上の区画が形成されていても構わない。 (1) In the above embodiment, the inside of the holding frames 2, 32, 42, 52 of the electric wire holders 1, 31, 41, 51 is separated by two sections 2b, 2c having different sizes. It is shown as an example. However, at least three or more compartments may be formed as long as they include two compartments having a magnitude relationship.
　（２）上記の実施の形態では、電線保持具１、３１、４１、５１の保持枠２、３２、４２、５２内は、大きさの異なる２つの区画２ｂ、２ｃが、張線器１０１（又は挟持固定部８）から遠ざかる方向に向けて一列に並んでいる構成を例として示した。しかし、少なくとも張線器（又は挟持固定部）に近い側に大きい側の区画が形成されていれば、小さい側の区画は、張線器（又は挟持固定部）から遠ざかる方向に一列に並んでいなくても構わない。 (2) In the above embodiment, in the holding frames 2, 32, 42, 52 of the electric wire holders 1, 31, 41, 51, two sections 2b, 2c having different sizes are provided with a wire tensioner 101 (2). Alternatively, a configuration in which they are lined up in a row in a direction away from the pinching fixing portion 8) is shown as an example. However, if at least the large compartment is formed on the side closer to the wire tensioner (or the pinch fixing portion), the smaller compartments are lined up in a row in the direction away from the wire tensioner (or the pinch fixing portion). You don't have to.
　（３）上記の実施の形態では、保持枠２、３２、４２、５２に形成された開口２ａは、何れも、大きい区画２ｂ側に形成された構成を例として示した。しかし、開口は小さい側の区画に対して形成されていても良いし、また、両方の区画に対して大きく開くように形成されていても構わない。さらに、両方の区画に対して開口が形成される場合、単一の開口ではなく、それぞれに別個に形成されていても構わない。 (3) In the above embodiment, the openings 2a formed in the holding frames 2, 32, 42, and 52 are all shown as an example of the configuration formed on the large compartment 2b side. However, the openings may be formed for the smaller compartments or may be formed to open wider for both compartments. Further, if openings are formed for both compartments, they may be formed separately for each rather than a single opening.
　（４）上記の実施の形態では、把持部１０のハンドル１０ｂが、張線器１０１の伸縮棒に対して平行に延びるように形成された構成を例として示した。しかし、旋回操作のためのハンドルは、張線器１０１の伸縮方向と平行に形成されていなくても構わない。例えば、張線器１０１の伸縮方向に対して直交する方向へ延びるように形成されていても構わない。また、ハンドル１０ｂのように対称に２本形成される構成に限らず、一方側であっても構わない。 (4) In the above embodiment, a configuration in which the handle 10b of the grip portion 10 is formed so as to extend parallel to the telescopic rod of the wire tensioning device 101 is shown as an example. However, the handle for the turning operation does not have to be formed parallel to the expansion / contraction direction of the wire tensioning device 101. For example, it may be formed so as to extend in a direction orthogonal to the expansion / contraction direction of the wire tensioning device 101. Further, the configuration is not limited to the configuration in which two symmetrically formed handles such as the handle 10b, and one side may be used.
　（５）上記の実施の形態では、把持部１０のハンドル１０ｂは、当板部１０ａを超える長さに形成された構成を例として示した。しかし、安定して保持できる構成であれば、ハンドルが当板部よりも短い形状であっても構わない。 (5) In the above embodiment, the handle 10b of the grip portion 10 is shown as an example of a configuration formed to have a length exceeding the plate portion 10a. However, the handle may have a shape shorter than that of the plate portion as long as it can be stably held.
