そして、イメージとしてはこの状態で一対の挟持プレート２の間に電力線７及び分岐線８を単に移動させればよいのであるが、この作業は実際には容易ではない。 Furthermore, in the high-voltage edge line fixture 1 according to the present embodiment, in addition to the above-described configuration, for example, as shown in FIG. When the plate 2 is viewed in plan, the locking members 6a and 6b may be provided one by one so as to be positioned diagonally.
By providing the locking members 6a and 6b, when the power line 7 and the branch line 8 are accommodated in the gap 3 formed between the pair of sandwiching plates 2, the power line 7 and the branch line 8 move from the gap 3. Can be prevented.
This point will be described in more detail with reference to FIG.
FIG. 2 is a conceptual diagram showing a state in which a pair of clamping plates in the high-pressure edge line fixture according to the embodiment of the present invention is separated. The same parts as those shown in FIGS. 1 and 9 are denoted by the same reference numerals, and description of the configuration is omitted.
In order to hold the power line 7 and the branch line 8 between the pair of sandwiching plates 2 in the high-voltage edge line fixture 1 according to the present embodiment, first, the gap adjusting unit 4 is operated and shown in FIG. As described above, the gap 3 between the lower clamping plate 2a and the upper clamping plate 2b is widened.
As an image, the power line 7 and the branch line 8 may be simply moved between the pair of sandwiching plates 2 in this state, but this operation is not easy in practice.

通常、電力線７等に対する作業を行う場合、作業員は、電力線７等に直接触れると危険なので、単に電力線７や分岐線８を動かすだけでも必ず間接活線工具を使用する。また、間接活線工具（例えば、ヤットコ、共用操作棒等）の操作は、通常、両手により行うので、一度に一人で操作できる間接活線工具は１つである。
さらに、電力線７等に対する作業は、通常、二人で行う場合が多く、電力線７と分岐線８をそれぞれ別々の間接活線工具で個別に保持しつつ、これらとは別の間接活線工具を用いて高圧縁線固定具１の操作を行うことは現実的ではなかった。つまり、２人の人員で３つの間接活線工具を操作することは困難である。
このような事情に鑑み、本実施の形態に係る高圧縁線固定具１では、一対の挟持プレート２の間に電力線７及び分岐線８を収容した場合に、その状態を維持できるように補助具を備えていることが望ましく、このような補助具として機能するものが、図１，２に示す上挟持プレート２ｂの長手方向端部に一体に固設される係止部材６ａ，６ｂである。 Normally, when working on the power line 7 or the like, it is dangerous for an operator to directly touch the power line 7 or the like. Therefore, the indirect live tool is always used even if the power line 7 or the branch line 8 is simply moved. Moreover, since the operation of an indirect hot-wire tool (for example, Yatco, a common operation bar, etc.) is normally performed with both hands, there is only one indirect hot-wire tool that can be operated by one person at a time.
Furthermore, the work on the power line 7 or the like is usually performed by two people, and while holding the power line 7 and the branch line 8 individually with separate indirect hot line tools, separate indirect hot line tools are used. It was not practical to use and operate the high-voltage edge line fixture 1. That is, it is difficult to operate three indirect hot tools with two personnel.
In view of such circumstances, in the high-voltage edge line fixture 1 according to the present embodiment, when the power line 7 and the branch line 8 are accommodated between the pair of sandwiching plates 2, the auxiliary tool can be maintained. It is desirable to include the locking members 6a and 6b integrally functioningly fixed to the longitudinal ends of the upper clamping plate 2b shown in FIGS.

なお、本実施の形態に係る高圧縁線固定具１では、係止部材６ａ，６ｂを、Ｌ字形のフック体により構成し、これらを上挟持プレート２ｂに固設している。この場合、係止部材６ａ，６ｂの軸部Ｐは、下挟持プレート２ａが配される側に突設され、かつ、その先端の鉤部Ｑは、上挟持プレート２ｂの長手方向中心軸側を向くように屈曲している。
このように、上挟持プレート２ｂが係止部材６ａ及び係止部材６ｂを備えることで、一対の挟持プレート２の間の空隙３に収容された電力線７を係止部材６ａにより、分岐線８を係止部材６ｂによりそれぞれ係止して保持しておくことができる。
つまり、一対の挟持プレート２の間の空隙３に電力線７及び分岐線８を保持しておくために、その都度間接活線工具を使用して電力線７及び分岐線８を保持しておく必要がなくなる。
この結果、電力線７の分岐点９近傍における電力線７及び分岐線８に本実施の形態に係る高圧縁線固定具１を取り付ける作業を、より少ない数の間接活線工具（より具体的には、２つの間接活線工具）を用いて行うことができる。よって、本実施の形態に係る高圧縁線固定具１の取付け作業を簡素化できる。
なお、図１，２では、係止部材６ａ，６ｂとして平面形状がＬ字形であるフック体を用いる場合を例に挙げて説明しているが、このフック体の平面形状は、湾曲状であってもよい。 In the high-voltage edge line fixture 1 according to the present embodiment, the locking members 6a and 6b are constituted by L-shaped hook bodies, which are fixed to the upper holding plate 2b. In this case, the shaft portion P of the locking members 6a and 6b protrudes on the side where the lower sandwiching plate 2a is disposed, and the flange portion Q at the tip of the shaft portion P is located on the longitudinal central axis side of the upper sandwiching plate 2b. Bent to face.
Thus, the upper clamping plate 2b includes the locking member 6a and the locking member 6b, so that the power line 7 accommodated in the gap 3 between the pair of clamping plates 2 is connected to the branch line 8 by the locking member 6a. Each of the locking members 6b can be locked and held.
That is, in order to hold | maintain the power line 7 and the branch line 8 in the space | gap 3 between a pair of clamping plates 2, it is necessary to hold | maintain the power line 7 and the branch line 8 using an indirect hot wire tool each time. Disappear.
As a result, an operation of attaching the high-voltage edge line fixture 1 according to the present embodiment to the power line 7 and the branch line 8 in the vicinity of the branch point 9 of the power line 7 is performed with a smaller number of indirect live tool (more specifically Two indirect hot wire tools). Therefore, the attachment work of the high-voltage edge line fixture 1 according to the present embodiment can be simplified.
In FIGS. 1 and 2, the case where a hook body having an L shape in plan is used as the locking members 6a and 6b is described as an example. However, the plane shape of the hook body is curved. May be.

なお、本実施の形態に係る高圧縁線固定具１では、上挟持プレート２ｂにおいて対角に位置する一組の角部に係止部材６ａ及び係止部材６ｂを個別に備えている。
この場合、一対の挟持プレート２の間に形成される空隙３に、例えば、分岐線８を収容しようとする場合は、図２に示すように、挟持プレート２の長手方向を分岐線８の伸長方向に沿うように配してから、分岐線８を係止部材６ｂの鉤部Ｑの下をくぐらせるようにして上挟持プレート２ｂの真下に移動させ、この後、分岐線８を上挟持プレート２ｂの中心軸側から係止部材６ａの軸部Ｐの横に移動させればよい。
また、挟持プレート２の他の側縁側に配される電力線７（図示せず）についても同様の手順により係止部材６ａに係止させることができる。 In addition, in the high voltage | pressure edge line fixing tool 1 which concerns on this Embodiment, the locking member 6a and the locking member 6b are separately provided in a pair of corner | angular parts located diagonally in the upper clamping plate 2b.
In this case, for example, when the branch line 8 is to be accommodated in the gap 3 formed between the pair of sandwiching plates 2, the longitudinal direction of the sandwiching plate 2 is extended as shown in FIG. 2. After being arranged along the direction, the branch line 8 is moved directly below the upper clamping plate 2b so as to pass under the flange portion Q of the locking member 6b, and then the branch line 8 is moved to the upper clamping plate. What is necessary is just to move to the side of the axial part P of the locking member 6a from the central-axis side of 2b.
Further, the power line 7 (not shown) arranged on the other side edge side of the clamping plate 2 can be locked to the locking member 6a by the same procedure.

なお、図１，２に示す本実施の形態に係る高圧縁線固定具１では、上挟持プレート２ｂの角部の全てに係止部材６ａ又は係止部材６ｂを設けおいてもよいが、この場合は、係止部材６ａ，６ｂによる電力線７及び分岐線８の保持効果が向上する一方で、挟持プレート２の間に形成される空隙３への電力線７及び分岐線８の出し入れがやや困難になるというデメリットが生じることが予想される。
また、本実施の形態に係る高圧縁線固定具１では、上挟持プレート２ｂに係止部材６ａ，６ｂを固設する場合を例に挙げて説明しているが、係止部材６ａ，６ｂは下挟持プレート２ａに設けてもよい。 In addition, in the high-voltage edge line fixture 1 according to the present embodiment shown in FIGS. 1 and 2, the locking member 6a or the locking member 6b may be provided on all corners of the upper clamping plate 2b. In this case, the holding effect of the power lines 7 and the branch lines 8 by the locking members 6a and 6b is improved, while the power lines 7 and the branch lines 8 are slightly difficult to put in and out of the gaps 3 formed between the holding plates 2. It is expected that there will be a demerit.
Moreover, in the high voltage | pressure edge line fixing tool 1 which concerns on this Embodiment, although the case where fixing member 6a, 6b is fixed to the upper clamping plate 2b is mentioned as an example, the locking member 6a, 6b is described. You may provide in the lower clamping plate 2a.

さらに、本実施の形態に係る高圧縁線固定具１では、下挟持プレート２ａと上挟持プレート２ｂを近接させた場合に、上挟持プレート２ｂに固設される係止部材６ａ，６ｂが、下挟持プレート２ａに干渉することがないよう配慮する必要がある。
このため、例えば、本実施の形態に係る高圧縁線固定具１では、上挟持プレート２ｂの長手方向の長さを、下挟持プレート２ａよりもわずかに長くしておき、下挟持プレート２ａに上挟持プレート２ｂを重ね合せた際に、それぞれの角部が完全に重なり合わないようにしている。
なお、上述以外の方法としては、例えば、下挟持プレート２ａと上挟持プレート２ｂを同じ大きさにしておき、係止部材６ａ，６ｂを、係止部材６ａ，６ｂを固設しない側の挟持プレート２と干渉しないように、挟持プレート２の長手方向端面に突設してもよい。
なお、下挟持プレート２ａと上挟持プレート２ｂを近接させた際に、係止部材６ａ，６ｂが、それが固設されない他の挟持プレート２に干渉しないように取付けられるのであれば、その取付け方法は問題としない。 Furthermore, in the high-voltage edge line fixture 1 according to the present embodiment, when the lower clamping plate 2a and the upper clamping plate 2b are brought close to each other, the locking members 6a and 6b fixed to the upper clamping plate 2b are Care must be taken not to interfere with the clamping plate 2a.
For this reason, for example, in the high-voltage edge line fixture 1 according to the present embodiment, the length of the upper clamping plate 2b in the longitudinal direction is slightly longer than the lower clamping plate 2a, and the upper clamping plate 2a is When the sandwiching plates 2b are overlapped, the respective corner portions are prevented from being completely overlapped.
As a method other than the above, for example, the lower clamping plate 2a and the upper clamping plate 2b are made the same size, and the locking members 6a and 6b are held on the side where the locking members 6a and 6b are not fixed. 2 may protrude from the end face in the longitudinal direction of the holding plate 2 so as not to interfere with the holding plate 2.
In addition, when the lower clamping plate 2a and the upper clamping plate 2b are brought close to each other, if the locking members 6a and 6b are mounted so as not to interfere with other clamping plates 2 that are not fixed, the mounting method Is not a problem.

ここで、図３を参照しながら電力線７の分岐点９の近傍に本実施の形態に係る高圧縁線固定具１を取り付ける際の具体的な手順について説明する。
図３は本発明の実施の形態に係る高圧縁線固定具の一対の挟持プレートの間の空隙に電力線及び分岐線を収容する際の手順を示す側面図である。なお、図１，２，９に記載されたものと同一部分については同一符号を付し、その構成についての説明は省略する。
本実施の形態に係る高圧縁線固定具１の一対の挟持プレート２の間の空隙３に電力線７及び分岐線８を収容するには、図３に示すように、分岐点９から離れた位置から分岐点９に近づけるように高圧縁線固定具１を移動させつつ、その過程でまず、係止部材６ｂに分岐線８を係止させて分岐線８を一対の挟持プレート２の間に保持し、この後、さらに高圧縁線固定具１を分岐点９に近づけながら、今度は電力線７を係止部材６ａに係止させて、電力線７を一対の挟持プレート２の間に保持して、この状態で所望量だけ高圧縁線固定具１を分岐点９に近づければよい。 Here, a specific procedure for attaching the high-voltage edge line fixture 1 according to the present embodiment near the branch point 9 of the power line 7 will be described with reference to FIG.
FIG. 3 is a side view showing a procedure when the power line and the branch line are accommodated in the gap between the pair of clamping plates of the high-voltage edge line fixture according to the embodiment of the present invention. In addition, the same code | symbol is attached | subjected about the same part as what was described in FIG.1, 2,9, and description about the structure is abbreviate | omitted.
In order to accommodate the power line 7 and the branch line 8 in the gap 3 between the pair of sandwiching plates 2 of the high-voltage edge line fixture 1 according to the present embodiment, as shown in FIG. First, in the process, the branch line 8 is locked to the locking member 6b and the branch line 8 is held between the pair of sandwiching plates 2 while moving the high-voltage edge line fixture 1 so as to approach the branch point 9 from Then, while further bringing the high-voltage edge line fixture 1 closer to the branch point 9, this time, the power line 7 is locked to the locking member 6a, and the power line 7 is held between the pair of sandwiching plates 2, In this state, the high-pressure edge line fixture 1 may be brought closer to the branch point 9 by a desired amount.

なお、この時、空隙調整部４を、電力線７及び分岐線８の間に侵入させることで、空隙調整部４を電力線７と分岐線８のスペーサーとして利用できる。これにより、一対の挟持プレート２の間において電力線７及び分岐線８を平行に保持することができる。
他方、一対の挟持プレート２の間に配設される電力線７と分岐線８が平行でない場合は、電力線７又は分岐線８の局所に大きな押圧力が作用して、断線等の不具合が生じる恐れがあり、好ましくない。
また、この作業は、本実施の形態に係る高圧縁線固定具１を所望の位置に保持しておくための間接活線工具と、必要に応じて分岐線８や電力線７を係止部材６ｂや係止部材６ａに係止させるための間接活線工具の、合計２つの間接活線工具を用いて行うことができるので、二人の人員で支障なく作業を完了できる。 At this time, by allowing the gap adjusting unit 4 to enter between the power line 7 and the branch line 8, the gap adjusting unit 4 can be used as a spacer for the power line 7 and the branch line 8. Thereby, the power line 7 and the branch line 8 can be held in parallel between the pair of sandwiching plates 2.
On the other hand, when the power line 7 and the branch line 8 disposed between the pair of sandwiching plates 2 are not parallel, a large pressing force acts on the local area of the power line 7 or the branch line 8 to cause a problem such as disconnection. Is not preferable.
In addition, this work includes an indirect hot-wire tool for holding the high-voltage edge line fixture 1 according to the present embodiment in a desired position, and the branch line 8 and the power line 7 as required by the locking member 6b. Since a total of two indirect hot-wire tools for engaging with the locking member 6a can be used, the work can be completed with no trouble by two persons.

そして、図３において一対の挟持プレート２の間に電力線７及び分岐線８を平行に配しながら収容した状態を、図３中の符号Ａで示す方向から見た状態を示したものが図４である。
また、先の図３では、電力線７と分岐線８とが鉛直方向に並設され、かつ、挟持プレート２の平面方向を鉛直方向に向けて作業する場合を例に挙げて説明しているが、電力線７及び分岐線８はともに可撓性を有しているので、電力線７と分岐線８を水平方向に平行に配し、かつ、挟持プレート２の平面方向を水平方向に向けた状態で高圧縁線固定具１の着脱作業を行ってもよい。
特に、この場合、動力受け部５に間接活線工具を嵌設して本実施の形態に係る高圧縁線固定具１を下から支えるようにして支持することができるので、高圧縁線固定具１の着脱作業時の作業性が一層向上する。
なお、本実施の形態に係る高圧縁線固定具１において、動力受け部５は、一対の挟持プレート２を保持しておくための間接活線工具を装着するための装着部としても機能する。つまり、この動力受け部５に、例えば、共用操作棒の頭部を接続することで、共用操作棒により高圧縁線固定具１を支えながら、保持しておくことができる。 FIG. 4 shows a state in which the power line 7 and the branch line 8 are accommodated in parallel between the pair of sandwiching plates 2 in FIG. 3 as viewed from the direction indicated by the symbol A in FIG. It is.
Further, in FIG. 3, the case where the power line 7 and the branch line 8 are arranged in the vertical direction and the plane direction of the sandwiching plate 2 is directed in the vertical direction is described as an example. Since both the power line 7 and the branch line 8 are flexible, the power line 7 and the branch line 8 are arranged in parallel in the horizontal direction, and the plane direction of the sandwiching plate 2 is oriented in the horizontal direction. You may perform the attachment or detachment operation | work of the high voltage | pressure edge line fixing tool 1. FIG.
In particular, in this case, an indirect hot wire tool can be fitted into the power receiving portion 5 to support the high pressure edge line fixture 1 according to the present embodiment from below, so that the high pressure edge line fixture can be supported. The workability at the time of attaching / detaching 1 is further improved.
In the high-voltage edge line fixture 1 according to the present embodiment, the power receiving portion 5 also functions as a mounting portion for mounting an indirect hot wire tool for holding the pair of sandwiching plates 2. In other words, for example, by connecting the head of the common operation rod to the power receiving portion 5, the high pressure edge line fixture 1 can be supported and held by the common operation rod.

次に、図４を参照しながら、本実施の形態に係る高圧縁線固定具１の挟持プレート２により電力線７及び分岐線８を挟持して固定する手順について詳細に説明する。
図４（ａ）は本発明の実施の形態に係る一対の挟持プレートにより電力線及び分岐線を挟持する前の状態を挟持プレートの端面方向から見た図であり、（ｂ）は本発明の実施の形態に係る一対の挟持プレートにより電力線及び分岐線を挟持している状態を挟持プレートの端面方向から見た図である。なお、図１乃至図３，９に記載されたものと同一部分については同一符号を付し、その構成についての説明は省略する。
先の図３においても説明したように、一対の挟持プレート２の間に形成される空隙３に電力線７と分岐線８を収容した後、一対の挟持プレート２の空隙３を狭めることで、一対の挟持プレート２を固定することができる。
より具体的には、図４（ａ）に示すように、本実施の形態に係る高圧縁線固定具１の動力受け部５に形成される係止溝（後段において説明する図８の係止溝１９を参照）に、例えば、共用操作棒１１の頭部に突設される突起１１ａを掛着して、共用操作棒１１をその中心軸を基軸に所望方向に回転させることで、空隙調整部４が作動して下挟持プレート２ａと上挟持プレート２ｂの間の空隙３が狭まり、最終的には、図４（ｂ）で示すように、一対の挟持プレート２により電力線７及び分岐線８を固定することができる。
なお、この状態を斜視図で示したものが図５である。
また、動力受け部５を操作するものとしては、共用操作棒１１以外の間接活線工具を用いることができる。この場合、動力受け部５の形態を、その操作に用いようとする間接活線工具を接続できるよう構成しておく必要がある。 Next, a procedure for holding and fixing the power line 7 and the branch line 8 by the holding plate 2 of the high-voltage edge line fixture 1 according to the present embodiment will be described in detail with reference to FIG.
FIG. 4A is a view of the state before the power line and the branch line are sandwiched by the pair of sandwiching plates according to the embodiment of the present invention, as viewed from the end face direction of the sandwiching plate, and FIG. It is the figure which looked at the state which is pinching a power line and a branch line with a pair of clamping plates concerning the form from the end face direction of the clamping plate. The same parts as those described in FIGS. 1 to 3 and 9 are denoted by the same reference numerals, and description of the configuration is omitted.
As described above with reference to FIG. 3, the power line 7 and the branch line 8 are accommodated in the gap 3 formed between the pair of clamping plates 2, and then the gap 3 of the pair of clamping plates 2 is narrowed. The clamping plate 2 can be fixed.
More specifically, as shown in FIG. 4A, a locking groove formed in the power receiving portion 5 of the high-voltage edge line fixture 1 according to the present embodiment (the locking shown in FIG. 8 described later). For example, a protrusion 11a protruding from the head of the common operation rod 11 is hooked on the groove 19), and the common operation rod 11 is rotated in the desired direction with the central axis as a base axis, thereby adjusting the gap. The portion 4 is actuated to narrow the gap 3 between the lower clamping plate 2a and the upper clamping plate 2b, and finally, as shown in FIG. Can be fixed.
FIG. 5 is a perspective view showing this state.
Moreover, as what operates the power receiving part 5, an indirect hot wire tool other than the common operation rod 11 can be used. In this case, it is necessary to configure the configuration of the power receiving portion 5 so that an indirect hot wire tool to be used for the operation can be connected.

図５は本発明の実施の形態に係る高圧縁線固定具により電力線及び分岐線を固定した状態を示す概念図である。また、図１乃至図４，９に記載されたものと同一部分については同一符号を付し、その構成についての説明は省略する。
図５に示すように、一対の挟持プレート２の間に電力線７及び分岐線８が挟持される場合、挟持プレート２の中央に配置される空隙調整部４は、電力線７及び分岐線８を分離するスペーサーとして機能する。 FIG. 5 is a conceptual diagram showing a state in which the power line and the branch line are fixed by the high-voltage edge line fixture according to the embodiment of the present invention. Also, the same parts as those described in FIGS. 1 to 4 and 9 are denoted by the same reference numerals, and description of the configuration will be omitted.
As shown in FIG. 5, when the power line 7 and the branch line 8 are sandwiched between the pair of sandwiching plates 2, the gap adjustment unit 4 disposed in the center of the sandwiching plate 2 separates the power line 7 and the branch line 8. Functions as a spacer.

続いて、図６を参照しながら本実施の形態に係る高圧縁線固定具１の空隙調整部及びそれを作動させる動力伝達機構について詳細に説明する。
図６は本発明の実施の形態に係る高圧縁線固定具における空隙調整部及び動力伝達機構の一例を模式的に示す概念図である。なお、図１乃至図５，９に記載されたものと同一部分については同一符号を付し、その構成についての説明は省略する。
本実施の形態に係る高圧縁線固定具１の空隙調整部４は、図６に示すように、例えば、下挟持プレート２ａを貫通して挿設され、上挟持プレート２ｂに螺設される２本のネジ棒１２ａ，１２ｂと、このネジ棒１２ａ，１２ｂをその中心軸を基軸に正逆回動させる動力伝達機構１３Ａとにより構成されるものである。
より具体的には、動力伝達機構１３Ａは、例えば、図６に示すように、動力受け部５の頂部に一体に固設される笠歯車１５ａを備えた動力伝達軸１４ａと、笠歯車１５ｂ，１５ｄを備えた動力伝達軸１４ｂと、笠歯車１５ｃ，１５ｅを備えた動力伝達軸１４ｃとにより構成されている。
また、動力伝達機構１３Ａから供給される動力を受け入れるために、２本のネジ棒１２ａ，１２ｂの上挟持プレート２ｂに螺設されない側の端部は、それぞれ笠歯車１５ｆ，１５ｇを備えている。 Next, the gap adjusting portion of the high-voltage edge line fixture 1 according to the present embodiment and the power transmission mechanism that operates the same will be described in detail with reference to FIG.
FIG. 6 is a conceptual diagram schematically showing an example of a gap adjusting portion and a power transmission mechanism in the high-voltage edge line fixture according to the embodiment of the present invention. The same parts as those described in FIGS. 1 to 5 and 9 are denoted by the same reference numerals, and description of the configuration is omitted.
As shown in FIG. 6, the gap adjusting portion 4 of the high-voltage edge line fixture 1 according to the present embodiment is inserted through the lower clamping plate 2a and is screwed into the upper clamping plate 2b, for example. The screw rods 12a and 12b, and the power transmission mechanism 13A for rotating the screw rods 12a and 12b forward and backward with the central axis as a base axis.
More specifically, as shown in FIG. 6, for example, the power transmission mechanism 13A includes a power transmission shaft 14a including a bevel gear 15a integrally fixed to the top of the power receiving portion 5, a bevel gear 15b, The power transmission shaft 14b having 15d and the power transmission shaft 14c having bevel gears 15c and 15e are configured.
Further, in order to receive the power supplied from the power transmission mechanism 13A, the end portions on the side not screwed to the upper clamping plate 2b of the two screw rods 12a and 12b are provided with bevel gears 15f and 15g, respectively.

そして、図６に示す本実施の形態に係る高圧縁線固定具１においては、共用操作棒１１の中心軸を基軸とする正逆方向の回転トルクが、動力伝達軸１４ａ及び笠歯車１５ａを介して、動力伝達軸１４ｂ，１４ｃに伝達され、さらに、動力伝達軸１４ｂに伝達された回転トルクが、笠歯車１５ｄ，１５ｆを介してネジ棒１２ａに、動力伝達軸１４ｃに伝達された回転力は笠歯車１５ｅ，１５ｇを介してネジ棒１２ｂに、それぞれ伝達される。
この結果、ネジ棒１２ａ及びネジ棒１２ｂがその中心軸を基軸に回動することで、ネジ棒１２ａ，１２ｂ上を上挟持プレート２ｂが、下挟持プレート２ａに近接するように、あるいは、下挟持プレート２ａから離間するようにスライドする。
従って、上述のような一連の動作により、一対の挟持プレート２による電力線７及び分岐線８の固定、並びに、電力線７及び分岐線８から一対の挟持プレート２の取り外しが可能になる。
このように、本実施の形態に係る高圧縁線固定具１によれば、電力線７及び分岐線８に対する着脱が容易で、かつ、繰り返し使用することができる耐用品としての高圧縁線固定具を提供できる。 In the high-voltage edge line fixture 1 according to the present embodiment shown in FIG. 6, the rotational torque in the forward and reverse directions based on the central axis of the common operation rod 11 is transmitted via the power transmission shaft 14a and the bevel gear 15a. Thus, the rotational torque transmitted to the power transmission shafts 14b and 14c and further transmitted to the power transmission shaft 14b is transmitted to the screw rod 12a via the bevel gears 15d and 15f, and the rotational force transmitted to the power transmission shaft 14c is It is transmitted to the screw rod 12b via the bevel gears 15e and 15g, respectively.
As a result, the screw rod 12a and the screw rod 12b rotate about the central axis thereof, so that the upper clamping plate 2b is close to the lower clamping plate 2a on the screw rods 12a and 12b, or the lower clamping plate Slide away from the plate 2a.
Therefore, the power line 7 and the branch line 8 can be fixed by the pair of sandwiching plates 2 and the pair of sandwiching plates 2 can be detached from the power line 7 and the branch line 8 by the series of operations as described above.
Thus, according to the high-voltage edge line fixture 1 according to the present embodiment, the high-voltage edge line fixture can be easily attached to and detached from the power line 7 and the branch line 8 and can be used repeatedly. Can be provided.

なお、本実施の形態に係る高圧縁線固定具１では、２本のネジ棒１２ａ，１２ｂにより上挟持プレート２ｂをスライドさせる場合を例に挙げて説明しているが、一対の挟持プレート２にネジ棒を２本以上設けてもよい。この場合、上挟持プレート２ｂの作動機構がやや複雑化するものの、挟持プレート２から電力線７及び分岐線８に対して作用する挟持力が均一化するので、高圧縁線固定具１により電力線７及び分岐線８を固定する場合に、電力線７や分岐線８の局所に負荷が集中するのを抑制できる。この場合、電力線７及び分岐線８に断線等の不具合が起こるリスクを小さくできる。
なお、一対の挟持プレート２の間に介設されるネジ棒が１本のみである場合は、空隙調整部４及び動力伝達機構１３Ａの構造を極めてシンプルにできるというメリットを有する。この反面、空隙調整部４のみでは下挟持プレート２ａと上挟持プレート２ｂを所望の空隙３を保ったまま平行に保持しておくことが難しいので、そのための構成を別途設ける必要がある。
このように、本実施の形態に係る高圧縁線固定具１の実用性と製造容易性の両者を考慮すると、２本のネジ棒１２ａ，１２ｂにより上挟持プレート２ｂを作動させるのが最良であると考えられる。 In addition, although the case where the upper clamping plate 2b is slid by the two screw rods 12a and 12b has been described as an example in the high-voltage edge line fixture 1 according to the present embodiment, Two or more screw rods may be provided. In this case, although the operation mechanism of the upper clamping plate 2b is slightly complicated, the clamping force acting on the power line 7 and the branch line 8 from the clamping plate 2 is made uniform, so that the power line 7 and When the branch line 8 is fixed, it is possible to suppress the load from being concentrated on the local area of the power line 7 or the branch line 8. In this case, it is possible to reduce the risk of problems such as disconnection in the power line 7 and the branch line 8.
In addition, when there is only one screw rod interposed between the pair of sandwiching plates 2, there is an advantage that the structure of the gap adjusting portion 4 and the power transmission mechanism 13A can be extremely simplified. On the other hand, since it is difficult to hold the lower clamping plate 2a and the upper clamping plate 2b in parallel while maintaining the desired gap 3 with only the gap adjusting portion 4, it is necessary to separately provide a configuration for that purpose.
Thus, considering both the practicality and the ease of manufacture of the high-voltage edge line fixture 1 according to this embodiment, it is best to operate the upper clamping plate 2b with the two screw rods 12a and 12b. it is conceivable that.

また、本実施の形態に係る高圧縁線固定具１では、上挟持プレート２ｂを作動させるネジ棒（例えば、ネジ棒１２ａ，１２ｂ）を２本以上備える場合でも、１つの動力受け部５を操作するだけで全てのネジ棒（例えば、ネジ棒１２ａ，１２ｂ）を同時に操作することができるので、操作性に優れた高圧縁線固定具を提供できる。よって、本実施の形態に係る高圧縁線固定具１の利便性を高めることができる。
なお、図６に示す高圧縁線固定具１では、ネジ棒１２ａ，１２ｂの下端部に取設される笠歯車１５ｆ，１５ｇ、及び、動力伝達機構１３Ａは、ケーシング１８内に収容されており、このケーシング１８の底面に、動力伝達軸１４ａに連結される動力受け部５が突設されている。 Further, in the high-voltage edge line fixture 1 according to the present embodiment, even when two or more screw rods (for example, screw rods 12a and 12b) for operating the upper clamping plate 2b are provided, one power receiving portion 5 is operated. All the screw rods (for example, the screw rods 12a and 12b) can be operated at the same time, so that it is possible to provide a high-pressure edge line fixture with excellent operability. Therefore, the convenience of the high-voltage edge line fixture 1 according to the present embodiment can be enhanced.
In the high-voltage edge line fixture 1 shown in FIG. 6, the bevel gears 15 f and 15 g and the power transmission mechanism 13 </ b> A installed at the lower ends of the screw rods 12 a and 12 b are accommodated in the casing 18. On the bottom surface of the casing 18, a power receiving portion 5 connected to the power transmission shaft 14a is projected.

さらに、本実施の形態に係る高圧縁線固定具１の動力伝達機構１３Ａの他の形態について図７を参照しながら説明する。
図７は本発明の実施の形態に係る高圧縁線固定具における空隙調整部及び動力伝達機構の他の例を模式的に示す概念図である。なお、図１乃至図６，９に記載されたものと同一部分については同一符号を付し、その構成についての説明は省略する。
本実施の形態に係る高圧縁線固定具１では、先の図６に示すような動力伝達機構１３Ａに代えて、図７に示すような動力伝達機構１３Ｂを備えていてもよい。
より具体的には、笠歯車１５ａを備える動力伝達軸１４ａや、笠歯車１５ｂ〜１５ｅを備える動力伝達軸１４ｂ，１４ｃ、及び、笠歯車１５ｆ，１５ｇに代えて、プーリ１６ａ，１６ｂを備えた動力伝達軸１４ｄ及び動力伝達ベルト１７ａ，１７ｂからなる動力伝達機構１３Ｂを備えることで、ネジ棒１２ａ，１２ｂをそれぞれの中心軸を基軸に回動させることができるよう構成してもよい。
この場合は、ネジ棒１２ａ，１２ｂのそれぞれの上挟持プレート２ｂに螺設されない側の端部にもプーリ１６ｃ，１６ｄを設けておく必要がある。 Furthermore, another embodiment of the power transmission mechanism 13A of the high-voltage edge line fixture 1 according to the present embodiment will be described with reference to FIG.
FIG. 7 is a conceptual diagram schematically showing another example of the air gap adjusting portion and the power transmission mechanism in the high-voltage edge line fixture according to the embodiment of the present invention. The same parts as those described in FIGS. 1 to 6 and 9 are denoted by the same reference numerals, and description of the configuration is omitted.
The high-voltage edge line fixture 1 according to the present embodiment may include a power transmission mechanism 13B as shown in FIG. 7 instead of the power transmission mechanism 13A as shown in FIG.
More specifically, the power transmission shaft 14a having the bevel gear 15a, the power transmission shafts 14b and 14c having the bevel gears 15b to 15e, and the power having the pulleys 16a and 16b instead of the bevel gears 15f and 15g. By providing the power transmission mechanism 13B composed of the transmission shaft 14d and the power transmission belts 17a and 17b, the screw rods 12a and 12b may be configured to be able to rotate about the respective central axes.
In this case, it is necessary to provide the pulleys 16c and 16d at the ends of the screw rods 12a and 12b that are not screwed to the upper clamping plate 2b.

図７に示すような動力伝達機構１３Ｂを備える場合も、先の図６に示す場合と同様に、本実施の形態に係る高圧縁線固定具１における２本のネジ棒１２ａ，１２ｂを、それぞれの中心軸を基軸に同時に回動させることができる。
より具体的には、図７に示す本実施の形態に係る高圧縁線固定具１では、共用操作棒１１の中心軸を基軸とする正逆方向の回転力が、動力伝達軸１４ｄ及び動力伝達ベルト１７ａ，１７ｂに伝達され、この後、動力伝達ベルト１７ａ，１７ｂからプーリ１６ｃ，１６ｄに動力が伝達され、最終的に、ネジ棒１２ａ，１２ｂに動力が伝達される。
この結果、先の図６に示す高圧縁線固定具１の場合と同様に、図７に示す高圧縁線固定具１においても、一対の挟持プレート２による電力線７及び分岐線８の固定、並びに、電力線７及び分岐線８から高圧縁線固定具１の取外し、を容易に行うことができる。
なお、図７に示す動力伝達機構１３Ｂを備える場合は、空隙調整部４としてネジ棒（例えば、ネジ棒１２ａ，１２ｂ）を２本以上備える場合でも、１つの動力受け部５の操作により容易に全てのネジ棒（例えば、ネジ棒１２ａ，１２ｂ）をその中心軸を基軸に回動操作することができる。この場合、一対の挟持プレート２の長手方向の長さが大きい高圧縁線固定具１を製造して提供できるというメリットがある。
なお、図７に示す高圧縁線固定具１では、ネジ棒１２ａ，１２ｂの下端部に取設されるプーリ１６ｃ，１６ｄ、及び、動力伝達機構１３Ｂはともに、ケーシング１８内に収容されており、このケーシング１８の底面に動力伝達軸１４ｄに連結される動力受け部５が突設されている。 Even when the power transmission mechanism 13B as shown in FIG. 7 is provided, the two screw rods 12a and 12b in the high-voltage edge line fixing device 1 according to the present embodiment are respectively connected to the power transmission mechanism 13B as shown in FIG. The central axis can be simultaneously rotated about the base axis.
More specifically, in the high-voltage edge line fixture 1 according to the present embodiment shown in FIG. 7, the rotational force in the forward and reverse directions with the central axis of the common operation rod 11 as the base axis is the power transmission shaft 14d and the power transmission. The power is transmitted to the belts 17a and 17b. Thereafter, the power is transmitted from the power transmission belts 17a and 17b to the pulleys 16c and 16d, and finally the power is transmitted to the screw rods 12a and 12b.
As a result, as in the case of the high-voltage edge line fixture 1 shown in FIG. 6, the power line 7 and the branch line 8 are fixed by the pair of clamping plates 2 in the high-voltage edge line fixture 1 shown in FIG. The high-voltage edge line fixture 1 can be easily removed from the power line 7 and the branch line 8.
When the power transmission mechanism 13B shown in FIG. 7 is provided, even when two or more screw rods (for example, screw rods 12a and 12b) are provided as the gap adjusting portion 4, it is easily operated by operating one power receiving portion 5. All the screw rods (for example, the screw rods 12a and 12b) can be rotated about the central axis. In this case, there is an advantage that the high-pressure edge line fixture 1 having a large length in the longitudinal direction of the pair of sandwiching plates 2 can be manufactured and provided.
In the high-voltage edge line fixture 1 shown in FIG. 7, the pulleys 16c, 16d and the power transmission mechanism 13B installed at the lower ends of the screw rods 12a, 12b are both housed in the casing 18. A power receiving portion 5 connected to the power transmission shaft 14d is provided on the bottom surface of the casing 18 in a projecting manner.

このような動力受け部５では、係止溝１９に共用操作棒１１の頭部に突設される突起１１ａ（図４を参照）を係合させることで、動力受け部５をその中心軸を基軸に回動操作することができる。
そして、この場合、動力伝達軸１４ａ又は動力伝達軸１４ｄから上述の図６，７に示す動力伝達機構１３Ａ，１３Ｂに動力が伝達される。
本実施の形態に係る高圧縁線固定具１は、図８に示すような動力受け部５を備えることで、従来公知の間接活線工具である共用操作棒１１を１つ用いるだけで、一対の挟持プレート２の間に介設される複数本のネジ棒（例えば、ネジ棒１２ａ，１２ｂ）を同時にそれぞれの中心軸を基軸に回動させて、空隙３の広狭を調整することができる。
そして、この動作により、本実施の形態に係る高圧縁線固定具１を用いて電力線７に分岐線８を固定する、あるいは、電力線７及び分岐線８から高圧縁線固定具１を取り外す、ことが可能になる。 Finally, the power receiving portion 5 of the high-voltage edge line fixture 1 according to the present embodiment will be described with reference to FIG.
