Description

本発明は、高圧の電気設備等に対する間接活線作業において使用される間接活線工法用クリップに関する。   The present invention relates to a clip for an indirect hot wire method used in an indirect hot wire work for a high voltage electric facility or the like.

間接活線作業では、充電した状態の高圧配電線(電線)に対して作業員が絶縁ヤットコ等の間接活線工具を用いて各種作業を行う。間接活線作業に際しては、例えば、間接活線工法用クリップ(絶縁シート挟み用器具)を用いて、電線の充電部分に被せた感電防止用の絶縁シートを電線と共に挟んで固定したり、切断によりフリーとなった電線を他の部位に仮固定するといった安全措置を講じる必要がある。この間接活線工法用クリップは、長尺のハンドル部を備えた絶縁ヤットコを用いて操作されるのが一般である。
図10(a)は従来の間接活線工法用クリップ(以下、クリップと称する)の構成例であり、このクリップ100は、2つの挟圧片101を開閉支持部材105によって開閉自在に支持すると共に、各挟圧片の先端部101aを常時接近(閉じる)方向へ付勢する図示しないバネを備えている。先端部が閉じた状態では後端部101bは図示のように離間した状態にあり、図10(b)に示すように絶縁ヤットコ120を用いてこの後端部101b同士を接近させる方向へ挟み込むことにより、各先端部101aを開放させることができる。
In the indirect hot wire work, an operator performs various work on the charged high-voltage distribution line (electric wire) by using an indirect hot wire tool such as an insulated Yatco. In indirect hot wire work, for example, by using an indirect hot wire clip (insulating sheet pinching tool), the electric shock prevention insulating sheet placed on the charged portion of the electric wire is sandwiched and fixed together with the electric wire, or by cutting It is necessary to take safety measures such as temporarily fixing the free wire to other parts. This indirect hot wire method clip is generally operated using an insulating jacket provided with a long handle portion.
FIG. 10A is a configuration example of a conventional clip for indirect hot wire construction (hereinafter referred to as a clip). The clip 100 supports two clamping pieces 101 by an opening / closing support member 105 so as to be opened and closed. In addition, a spring (not shown) that constantly biases (closes) the tip 101a of each pinching piece is provided. In the state where the front end portion is closed, the rear end portion 101b is in a separated state as shown in the figure, and as shown in FIG. Thus, each tip 101a can be opened.

また、同図(c)に示すように絶縁ヤットコの長手方向と直交する方向、その他の交差方向へクリップを保持して作業を行うこともできる。
しかし、従来のクリップを電線に取り付けた絶縁シートに挟み込んだり、絶縁シートから取り外す作業を行う際に、作業員の作業位置やアプローチ方法が限定される、という問題がある。高所作業車から延びるバケット140上に乗った作業においても周辺環境の影響によって作業が制限されることが多々ある。
特に、周辺の状況から高所作業車を使用できない場合には柱上に登ることになるが、その場合には柱上で安定した姿勢を維持しつつ効率的な作業を行うことが困難となることが多い。例えば、柱上では足場や姿勢や身体の動作が自由にならないため、クリップの着脱作業は更に制限を受けることとなる。
Further, as shown in FIG. 5C, the work can be performed while holding the clip in the direction orthogonal to the longitudinal direction of the insulating jacket and in other crossing directions.
However, there is a problem that the work position and approach method of the worker are limited when the conventional clip is sandwiched between the insulation sheets attached to the electric wires or removed from the insulation sheet. Even in a work on a bucket 140 extending from an aerial work vehicle, the work is often limited by the influence of the surrounding environment.
In particular, when an aerial work vehicle cannot be used due to surrounding conditions, it will be climbed on a pillar, but in that case it will be difficult to perform efficient work while maintaining a stable posture on the pillar There are many cases. For example, since the scaffolding, posture, and body movement are not free on the pillar, the clip attaching / detaching operation is further restricted.

図11は高所作業車のバケットに乗って間接活線作業を行っている状態を示した略図である。図11に基づいて従来のクリップの欠点を説明する。
図11に示した例では、一方の作業者Aは、電線130を内包した絶縁シート135を挟み込んでいるクリップ100を、絶縁ヤットコ120を用いて取り外そうとしているが、クリップの後端部が上向きとなっているため、下方からの作業でクリップの後端部を絶縁ヤットコの先端部で挟み込んでクリップ先端部を開放させることは容易ではない。また、クリップの後端部の幅方向(短辺方向)が電線とほぼ並行となっているため、図示のように電線と交差する方向から絶縁ヤットコをクリップ後端部に接近させる場合には、絶縁ヤットコ先端部でクリップ後端部を挟み込むことが更に困難となる。
図12(a)(b)はこのような状況を図示しており、図12(a)の紙面手前側、(b)の右側に作業者が位置していると仮定する。この場合には、絶縁ヤットコ120の先端によりクリップ100の後端部を引っ掛けて手前に引くことにより電線を中心としてクリップを回転させてクリップ後端部を手前側へ向けてから、クリップ後端部を絶縁ヤットコの先端部で挟み込んで開放させて離脱させることになる。しかし、この作業は極めて効率が悪く、疲労をもたらす。
或いは、作業者の位置を図12(a)の右、或いは左方向に変化させた上で、絶縁ヤットコを電線とほぼ並行にしてクリップ後端部を挟持する必要があった。しかし、周辺の状況がこのような作業を許さない場合には、クリップを取り外す作業は極めて困難となる。
FIG. 11 is a schematic view showing a state where the indirect hot-line work is performed on the bucket of an aerial work vehicle. The disadvantages of the conventional clip will be described with reference to FIG.
In the example shown in FIG. 11, one worker A tries to remove the clip 100 sandwiching the insulating sheet 135 containing the electric wire 130 using the insulating jacket 120, but the rear end of the clip is Since it is facing upward, it is not easy to open the clip leading end by sandwiching the trailing end of the clip with the leading end of the insulating jacket by work from below. Moreover, since the width direction (short side direction) of the rear end portion of the clip is substantially parallel to the electric wire, when the insulating jacket is made to approach the rear end portion of the clip from the direction intersecting with the electric wire as illustrated, It becomes more difficult to sandwich the rear end portion of the clip with the front end portion of the insulating jacket.
12 (a) and 12 (b) illustrate such a situation, and it is assumed that an operator is located on the front side of the sheet of FIG. 12 (a) and on the right side of FIG. 12 (b). In this case, the rear end portion of the clip 100 is hooked by the front end of the insulating jacket 120 and pulled toward the front side to rotate the clip around the electric wire so that the rear end portion of the clip faces the front side, and then the rear end portion of the clip. Is sandwiched between the tips of the insulating jacket and released to release it. However, this operation is extremely inefficient and causes fatigue.
Or after changing the operator's position to the right or left direction of Fig.12 (a), it was necessary to clamp the rear end of the clip with the insulating jacket substantially parallel to the electric wire. However, if the surrounding situation does not allow such work, the work of removing the clip becomes extremely difficult.

また、電線に掛けられた絶縁シート135をクリップにより挟み込む作業を絶縁ヤットコを用いて行うことは更に煩雑である。即ち、図11のように斜め下方、或いは横方向からの作業によってクリップを絶縁シートに挟み込むには、斜め下方向、或いは横方向から絶縁ヤットコにより保持したクリップ先端を電線に相当する絶縁シート部分にあてがって押し込んで絶縁シートを変形させながら、開放したクリップの挟圧片間に電線を内包した絶縁シートを入り込ませて挟み込む、といった煩雑な作業を行う必要がある。
或いは、絶縁ヤットコの長手方向に対するクリップの保持方向を図10(c)のように90度角度を持たせた上で、クリップの取付け作業を実施することも可能である。このような角度に保持したクリップ先端を開放させて電線に掛けられた絶縁シートの上辺に挟み込むには、電線とほぼ同じ高さまで作業者を上昇させつつ、絶縁ヤットコを電線とほぼ並行に保持しながら作業を行う必要がある。しかし、高所作業車のバケットの上昇可能な高さには限界がある。
In addition, it is more complicated to perform the operation of sandwiching the insulating sheet 135 that is hung on the electric wire with the clip using the insulating jacket. That is, as shown in FIG. 11, in order to sandwich the clip in the insulating sheet by working from the obliquely downward or lateral direction, the tip of the clip held by the insulating jacket from the obliquely downward direction or the lateral direction is used as the insulating sheet portion corresponding to the electric wire. It is necessary to perform a complicated operation of inserting and sandwiching the insulating sheet containing the electric wire between the pressing pieces of the opened clip while being pushed in and deforming the insulating sheet.
Alternatively, the clip can be attached after the holding direction of the clip with respect to the longitudinal direction of the insulating Yatco is 90 degrees as shown in FIG. 10C. In order to open the clip end held at such an angle and sandwich it between the upper sides of the insulating sheet hung on the electric wire, the operator is raised to almost the same height as the electric wire, while holding the insulating Yoko substantially parallel to the electric wire. It is necessary to work while. However, there is a limit to the height at which the bucket of an aerial work vehicle can be raised.

また、図11中に示したように切断することによってフリーとなった電線の端部131を同じ相の電線等132に沿わせてクリップで固定するが、この場合にも作業者Bは、クリップの形状に起因して、作業位置やアプローチ方法が限定される、という問題がある。
特許文献1には、鋏のように2つのクリップ片を一つの支点部を中心として開閉自在に構成し、各クリップ片の後端部に絶縁ヤットコの先端部を確実に保持させるための保持部材を設けた間接活線工法用クリップが開示されている。この間接活線工法用クリップによれば、降雪時、雨天時等の作業環境の悪化に左右されることなく、間接活線工法用クリップが絶縁ヤットコから脱落することを防止することができる、と記載されている。
しかし、この間接活線工法用クリップは、図10等に示した従来のクリップと同様の欠点を有していることが明かである。
Further, as shown in FIG. 11, the end 131 of the electric wire that has become free by cutting is fixed along with the electric wire 132 of the same phase with a clip. There is a problem that the work position and the approach method are limited due to the shape of the head.
Patent Document 1 discloses a holding member that is configured so that two clip pieces can be opened and closed around a single fulcrum portion like a ridge, and the leading end portion of the insulating jacket is securely held at the rear end portion of each clip piece. A clip for an indirect hot wire method is provided. According to this indirect hot wire method clip, it is possible to prevent the indirect hot wire method clip from falling off from the insulating Yatco without being affected by deterioration of the work environment such as during snowfall or rainy weather. Have been described.
However, it is clear that this indirect hot wire method clip has the same defects as the conventional clip shown in FIG.

特開2012−200089公報JP2012-200089

従来の間接活線工法用クリップは、長尺な絶縁ヤットコを用いて操作され、絶縁シート等を電線に固定したり離脱させる等の作業に用いられるが、作業者の位置やアプローチ方法が制限される場合には、電線に被せた絶縁シートに取り付けられたクリップの後端部が作業員の位置とは異なった方向へ向けて突出した状態となり易いため、クリップの着脱操作が煩雑であった。
即ち、従来の間接活線工法用クリップは、2つの挟圧片101を開閉支持部材105によって開閉自在に支持しているに過ぎず、各挟圧片の先端部101aと後端部101bとは、開閉支持部材105を間に挟んでほぼ同一直線状に配列されている。このため、作業対象物に対してある位置関係にある作業者にとって角度的にクリップ後端部を絶縁ヤットコ先端部で保持することが難しい場合には、作業位置を変える必要があったが、周辺の条件からして作業位置の変更が難しい場合には着脱作業が難航することがあった。
Conventional clips for indirect hot wire construction are operated using a long insulating jacket, and are used for work such as fixing or removing an insulation sheet, etc. from an electric wire, but the position and approach method of the operator is limited. In this case, since the rear end portion of the clip attached to the insulating sheet placed on the electric wire tends to protrude in a direction different from the position of the worker, the attachment / detachment operation of the clip is complicated.
That is, the conventional clip for indirect hot wire construction only supports the two pinching pieces 101 to be freely opened and closed by the opening and closing support member 105, and the front end portion 101a and the rear end portion 101b of each pressing piece are as follows. The opening / closing support members 105 are arranged in substantially the same straight line. For this reason, when it is difficult for an operator who has a certain positional relationship to the work object to hold the rear end of the clip with the insulating Yako tip in an angular manner, the work position must be changed. When it is difficult to change the work position due to the above conditions, the detachment work may be difficult.

本発明は上記に鑑みてなされたものであり、絶縁シート等の作業対象物を挟圧する間接活線工法用クリップ先端の開閉方向に対して、絶縁ヤットコによって保持されるクリップ後端の開閉方向を所定角度ずらして、クリップ後端部が作業員に向けて突出するようにした。このため、作業対象物に対する作業者の作業位置に関係なく、間接活線工法用クリップを電線等に被せた絶縁シート等の対象物に対して着脱する作業を容易化することができる間接活線工法用クリップを提供することを目的としている。   The present invention has been made in view of the above, and the opening / closing direction of the rear end of the clip held by the insulating Yatco with respect to the opening / closing direction of the front end of the clip for indirect hot wire construction that clamps a work object such as an insulation sheet The clip was shifted by a predetermined angle so that the rear end of the clip protruded toward the worker. For this reason, the indirect hot wire which can facilitate the operation | work which attaches / detaches with respect to objects, such as an insulation sheet which covered the clip for indirect hot wire methods on the electric wire etc. irrespective of the operator's work position with respect to a work subject. The purpose is to provide clips for construction methods.

以上の構成を備えた間接活線工法用クリップ1の操作手順について説明する。
Further, when the clamping pressure by the distal end portion of the insulating jacket is released, the movable operation piece 35 is separated from the fixed operation piece 4 by the urging force of the elastic member 30, and the non-clamping posture (opened) shown in FIG. The movable holding member 20 in the posture) is biased in the closing direction via the link piece, and shifts to the holding pressure posture (closed posture) shown in FIG.
In this way, the link piece 41 pivotally supported at both ends by the shaft support portion 36a provided on the slide member 36 of the movable operation piece 35 and the proximal end shaft support portion 27 of the movable holding member is connected to the movable operation piece 35. It plays a role of smoothly transmitting the driving force generated when moving forward and backward toward the fixed operation piece 4 to the movable holding member 20.
At this time, the link piece 41 can be stably operated by the slide member 36 of the movable operation piece 35 that reciprocally moves along a stable track along the guide hole 10.
The operation procedure of the indirect hot wire clip 1 having the above configuration will be described.

図1、図2(a)に示したように両挟持部材が挟圧姿勢(閉止姿勢)にある時には、可動操作片35は弾性部材30の力によって固定操作片4から離間した位置にある。
両挟持部材2、20を非挟圧姿勢(開放姿勢)に変位させるには、まず図2(a)のように両挟持部材2、20を絶縁ヤットコ50の先端部で保持してから、次いで(b)に示すように挟圧すればよい。絶縁ヤットコによって固定操作片4に向けて可動操作片35を押し付けると、ガイド穴10内に嵌合した可動操作片のスライド部材36がベース挟持部材2の先端部に向かって移動する。このため、軸支部36aを介して被軸支部41aを軸支されたリンク片41が、図2(a)→(b)、図3(a)→(b)に示すように軸支部36aを中心として時計回り方向へ回動しながら可動挟持部材20を軸支部8、及びピン28を中心として開放方向へ回動させる。
As shown in FIGS. 1 and 2A, when both the clamping members are in the clamping posture (closed posture), the movable operation piece 35 is located away from the fixed operation piece 4 by the force of the elastic member 30.
In order to displace both the clamping members 2 and 20 to the non-clamping posture (opening posture), first, hold both the clamping members 2 and 20 at the tip of the insulating jacket 50 as shown in FIG. What is necessary is just to pinch as shown in (b). When the movable operation piece 35 is pressed toward the fixed operation piece 4 by the insulating jacket, the slide member 36 of the movable operation piece fitted in the guide hole 10 moves toward the distal end portion of the base clamping member 2. For this reason, the link piece 41 pivotally supported by the pivoted support portion 41a via the pivot support portion 36a has the pivot support portion 36a as shown in FIGS. 2 (a) → (b) and FIG. 3 (a) → (b). The movable holding member 20 is rotated in the opening direction around the pivotal support portion 8 and the pin 28 while being rotated clockwise around the center.

図2(b)に示した絶縁ヤットコ50による挟圧状態を解消すると、弾性部材30の原形復帰力によって、図2(a)に示したように、両挟持部材2、20が挟圧姿勢に復帰する。
本発明のクリップにおいては、図9(a)(b)及び(c)に示すように、ベース挟持部材2の挟持部6と可動挟持部材20の挟持部24との接触位置と、回動軸支部(軸支部8、被軸支部22)とを結ぶ直線L1と、可動操作片35が進退する方向L2とが、平行(図9(a))となっているか、或いは鋭角状に交差している構成(図9(b)(c))が一つの特徴をなしている。
When the clamping state by the insulating jacket 50 shown in FIG. 2B is eliminated, the clamping members 2 and 20 are brought into a clamping posture by the original restoring force of the elastic member 30 as shown in FIG. Return.
In the clip of the present invention, as shown in FIGS. 9 (a), (b) and (c), the contact position between the clamping portion 6 of the base clamping member 2 and the clamping portion 24 of the movable clamping member 20, and the rotation shaft The straight line L1 connecting the support parts (the shaft support part 8 and the supported shaft support part 22) and the direction L2 in which the movable operation piece 35 advances and retreats are parallel (FIG. 9A) or intersect at an acute angle. The configuration (FIGS. 9B and 9C) has one feature.

換言すれば、本発明のクリップ1では、従来のクリップのように回動軸部を間に挟んで挟持部材の挟持部の延長上に操作片が存在していない。操作片4、35は、接触した状態にある2つの挟持部6、24と軸支部8、及び被軸支部22(回動軸支部)とを結んだ直線L1を横方向に回避した位置に配置され、且つ可動操作片35の移動方向が直線L1とほぼ並行(並行、鋭角状に交差する場合を含む)となっている。
このため、絶縁ヤットコの先端部の開閉方向と、クリップの挟持部材の開閉方向が交差することとなり、各操作片4、35の突出方向を作業員に向けることが可能となる。従って、作業対象物に対する絶縁ヤットコを操作する作業員の位置関係に関係なく、クリップを作業対象物に取り付けたり、取り外す作業性を高めることができる。
In other words, in the clip 1 of the present invention, there is no operation piece on the extension of the clamping portion of the clamping member with the rotating shaft portion interposed therebetween as in the conventional clip. The operation pieces 4 and 35 are arranged at positions avoiding a straight line L1 connecting the two holding portions 6 and 24 in contact with the shaft support portion 8 and the shaft support portion 22 (rotation shaft support portion) in the lateral direction. In addition, the moving direction of the movable operation piece 35 is substantially parallel to the straight line L1 (including the case where the movable operation piece 35 intersects in parallel and at an acute angle).
For this reason, the opening / closing direction of the front end of the insulating jacket intersects with the opening / closing direction of the clip clamping member, and the projecting direction of the operation pieces 4 and 35 can be directed to the worker. Therefore, the workability of attaching or detaching the clip to the work object can be improved regardless of the positional relationship of the worker who operates the insulating jacket with respect to the work object.

具体的には、二つ折りにして電線に被せた絶縁シート(挟圧対象物)を電線と共にクリップで挟んだり、挟んだ状態にあるクリップを絶縁シートから取り外すために絶縁ヤットコを操作する場合に、周辺環境の影響により高所作業車から延びるバケットの高さ位置が絶縁シートの挟着対象部位よりも大幅に低くなっているとしても、操作片の突出方向を作業員に向けることができる。このため、下からの作業によってクリップを絶縁シートに容易に挟着したり、取り外すことが可能となる。図2に示すように絶縁ヤットコ50が延びる方向(軸方向)に対して、クリップの挟持部材の挟持部6、24の方向が略90度ずれているため、電線よりも下からの作業によってクリップを着脱することが容易となる。   Specifically, when the insulating sheet (clamping object) that is folded in half and is covered with the electric wire is clipped with the electric wire, or when operating the insulating jacket to remove the clip in the pinched state from the insulating sheet, Even if the height position of the bucket extending from the aerial work vehicle is significantly lower than the portion to be sandwiched by the insulating sheet due to the influence of the surrounding environment, the protruding direction of the operation piece can be directed to the worker. For this reason, the clip can be easily sandwiched or removed from the insulating sheet by work from below. As shown in FIG. 2, since the direction of the clamping portions 6 and 24 of the clip clamping member is shifted by approximately 90 degrees with respect to the direction (axial direction) in which the insulating yoke 50 extends, the clip is operated by work from below the electric wire. It becomes easy to attach and detach.

このように本発明のクリップによれば、クリップの挟持部が延びる方向に対して、操作部が突出する方向を所定角度ずらしたので、操作部の突出方向を作業員に向け易くなる。このため、絶縁ヤットコを操作する作業者の作業位置を変化させたり、身体の向きを変化させる等の煩雑な作業を行うことなく、クリップを開閉操作してスムーズに挟圧対象物に対して着脱させることが可能となる。   As described above, according to the clip of the present invention, the direction in which the operation portion protrudes is shifted by a predetermined angle with respect to the direction in which the clip holding portion extends, so that the protrusion direction of the operation portion can be easily directed toward the worker. For this reason, the clip can be opened and closed smoothly and attached to the object to be clamped without changing the work position of the operator who operates the insulated Yatco or changing the direction of the body. It becomes possible to make it.

第1の本発明に係る間接活線工法用クリップ1は、中間部外側面に固定操作片4を備えると共に、先端に挟持部6を備えたベース挟持部材2と、該ベース挟持部材の基端部寄り位置に設けた軸支部8により基端部寄りに設けた被軸支部22を回動自在に軸支され、且つ先端部にベース挟持部材の挟持部6と接触可能な挟持部24を有した可動挟持部材20と、ベース挟持部材2に対して可動挟持部材20を閉じる方向へ付勢する弾性部材30と、固定操作片4よりも軸支部8寄りのベース挟持部材の外側面によって固定操作片に対して進退自在に支持された可動操作片35と、弾性部材30に抗して可動操作片を固定操作片に接近させた時に作動して可動挟持部材をベース挟持部材から離間させるリンク機構40と、を備え、ベース挟持部材の挟持部と可動挟持部材の挟持部との接触位置と、軸支部とを結ぶ直線L1と、可動操作片が進退する方向L2とが、平行、或いは鋭角状に交差することを特徴とする。
<Summary of Configuration, Action, and Effect of the Present Invention>
A clip for indirect hot wire construction method 1 according to the first aspect of the present invention includes a base clamping member 2 having a fixing operation piece 4 on an outer surface of an intermediate portion and a clamping portion 6 at a distal end, and a base end of the base clamping member A shaft support portion 22 provided near the base end portion is pivotally supported by a shaft support portion 8 provided near the base portion, and a pinching portion 24 that can contact the pinching portion 6 of the base pinching member is provided at the distal end portion. The fixed holding operation is performed by the movable holding member 20, the elastic member 30 that biases the movable holding member 20 in the closing direction with respect to the base holding member 2, and the outer surface of the base holding member closer to the shaft support portion 8 than the fixing operation piece 4. A movable operating piece 35 supported so as to be movable back and forth with respect to the piece, and a link mechanism that operates when the movable operating piece approaches the fixed operating piece against the elastic member 30 and separates the movable holding member from the base holding member. 40, and a base clamping member And the contact position between the clamping part of the clamping portion and the movable clamping member, the straight line L1 connecting the shaft support, and the direction L2 in which the movable operating member moves forward and backward are parallel, or wherein the cross at an acute angle shape.

従来のクリップは挟持対象物を挟持する各挟持部(先端部)の延びる方向と、絶縁ヤットコにより保持される各挟持部の延びる方向が、回動軸を間に挟んでほぼ同じ直線上に沿っていた。このため、従来のクリップを電線に取り付けた絶縁シートに挟み込んだり、絶縁シートから取り外す作業を行う際には、作業員の作業位置やアプローチ方法が限定される、という問題があった。高所作業車から延びるバケット上に乗った作業においても周辺環境の影響によって作業が制限されることが多々ある。
特に、周辺の状況から高所作業車を使用できない場合には柱上に登ることになるが、その場合には柱上で安定した姿勢を維持しつつ効率的な作業を行うことが困難となることが多かった。例えば、柱上では足場や姿勢や身体の動作が自由にならないため、クリップの着脱作業は更に制限を受けることとなる。
In the conventional clip, the extending direction of each clamping part (tip end part) that clamps the object to be clamped and the extending direction of each clamping part held by the insulating jacket are along substantially the same straight line with the rotating shaft in between. It was. For this reason, there has been a problem that the work position and approach method of the worker are limited when the conventional clip is sandwiched between the insulation sheets attached to the electric wires or the work is removed from the insulation sheet. Even when working on a bucket extending from an aerial work vehicle, the work is often limited by the influence of the surrounding environment.
In particular, when an aerial work vehicle cannot be used due to surrounding conditions, it will be climbed on a pillar, but in that case it will be difficult to perform efficient work while maintaining a stable posture on the pillar There were many things. For example, since the scaffolding, posture, and body movement are not free on the pillar, the clip attaching / detaching operation is further restricted.

例えば、図11に示した例では、クリップの後端部が上向きとなっているため、下方からの作業でクリップの後端部を絶縁ヤットコの先端部で挟み込んでクリップ先端部を開放させることは容易ではない。また、クリップの後端部の幅方向(短辺方向)が電線とほぼ並行となっているため、図示のように電線と交差する方向から絶縁ヤットコをクリップ後端部に接近させる場合には、絶縁ヤットコ先端部でクリップ後端部を挟み込むことが更に困難となる。   For example, in the example shown in FIG. 11, since the rear end of the clip is facing upward, it is possible to open the clip front end by sandwiching the rear end of the clip with the front end of the insulating jacket by work from below. It's not easy. Moreover, since the width direction (short side direction) of the rear end portion of the clip is substantially parallel to the electric wire, when the insulating jacket is made to approach the rear end portion of the clip from the direction intersecting with the electric wire as illustrated, It becomes more difficult to sandwich the rear end portion of the clip with the front end portion of the insulating jacket.

本発明では、絶縁ヤットコにより保持される各操作片が突出する方向(可動操作片の進退方向L2と直交する方向)が、挟持対象物を挟持する各挟持部の延びる方向(直線L1が延びる方向)と交差する方向となっており、各挟持部の延びる方向(L1)が絶縁ヤットコの軸方向の延長線と交差している。このため、絶縁ヤットコを操作する作業員が電線等の作業対象物よりも下方に位置している等、最適の作業位置、作業姿勢を確保できない不利な状況においても、操作片を作業員側に向けて突出した状態とすることができる。従って、操作片に向けて絶縁ヤットコを延ばしたときに、その先端部によって操作片を無理なく保持することができ、間接活線工法用クリップを電線等に被せた絶縁シート等の対象物に対して着脱する作業を容易化することができる。
特に、電線と交差する方向から絶縁ヤットコをクリップ後端部に接近させる場合においても、絶縁ヤットコ先端部でクリップ後端部を挟み込むことが容易となる。
In the present invention, the direction in which each operation piece held by the insulating yoke protrudes (the direction orthogonal to the advancing / retreating direction L2 of the movable operation piece) is the direction in which each holding portion that holds the object to be held (the direction in which the straight line L1 extends). ), And the extending direction (L1) of each clamping portion intersects the extension line in the axial direction of the insulating jacket. For this reason, even in disadvantageous situations where the optimal work position and work posture cannot be ensured, such as when the worker who operates the insulated Yatco is positioned below the work object such as an electric wire, the operation piece is placed on the worker side. It can be set as the state which protruded. Therefore, when the insulation jacket is extended toward the operation piece, the operation piece can be held without difficulty by the tip, and the object such as an insulation sheet with the indirect hot wire clip placed on the electric wire etc. The work of attaching and detaching can be facilitated.
In particular, even when the insulating jacket is made to approach the rear end of the clip from the direction intersecting the electric wire, it is easy to sandwich the rear end of the clip with the leading end of the insulating jacket.

可動挟持部材の被軸支部22よりも基端側に配置された基端軸支部27をリンク片41によって引いたり、押したりすることにより、可動挟持部材20を被軸支部22を中心としてスムーズに回動させることが可能となる。リンク機構40を構成する部品点数が少ないため、小型化、低コスト化を実現できる。
In the second aspect of the present invention, the link mechanism is supported by a base end shaft support portion 27 disposed on the base end side with respect to the shaft support portion of the movable holding member, and one end portion thereof rotatably supported by the base end shaft support portion. And a link piece 41 pivotally supported by the movable operation piece at the other end.
By pulling or pushing the base end shaft support portion 27 arranged on the base end side with respect to the shaft support portion 22 of the movable holding member with the link piece 41, the movable holding member 20 can be smoothly centered on the shaft support portion 22. It can be rotated. Since the number of parts constituting the link mechanism 40 is small, downsizing and cost reduction can be realized.

第3の本発明では、ベース挟持部材には、可動操作片のスライド部材をスライド自在に支持する長穴状のガイド穴10が形成されており、可動操作片にはガイド穴内に嵌合して該ガイド穴の長手方向に進退するスライド部材36が設けられ、リンク片の他端部はスライド部材36により回動自在に軸支されていることを特徴とする。
可動操作片をガイド穴に沿って進退させることにより、リンク片を介して可動挟持部材を回動させることができ、構成をコンパクト化することができる。
In the third aspect of the present invention, the base holding member is formed with a long hole-shaped guide hole 10 that slidably supports the slide member of the movable operation piece, and the movable operation piece is fitted into the guide hole. A slide member 36 that advances and retreats in the longitudinal direction of the guide hole is provided, and the other end of the link piece is pivotally supported by the slide member 36 so as to be rotatable.
By moving the movable operation piece back and forth along the guide hole, the movable holding member can be rotated via the link piece, and the configuration can be made compact.
