Description

本発明は、把持工具の補助部材に関する。詳しくは、間接活線工事において電線被覆剥ぎ取り工具を操作する把持工具の補助部材に関する。   The present invention relates to an auxiliary member for a gripping tool. In detail, it is related with the auxiliary member of the holding | grip tool which operates an electric wire sheath stripping tool in indirect hot wire construction.

従来より、高圧配電線路の変圧器工事等に伴う間接活線工事では、活線状態のままで電線被覆の剥ぎ取りから絶縁処理まで行う。そのため、絶縁棒を備える各種工具や絶縁棒の先端に取り付けられた先端工具を使用し、直接電線の通電部分に触れずに作業を進める。   Conventionally, in indirect hot line construction accompanying transformer construction of high-voltage distribution lines, etc., from the stripping of the wire coating to the insulation treatment is performed in the live line state. For this reason, various tools equipped with an insulating rod and tip tools attached to the tip of the insulating rod are used, and the work proceeds without directly touching the energized portion of the electric wire.

このような間接活線工事において、電線被覆の剥ぎ取り作業を行う際には、電線被覆剥取り工具が用いられる。電線被覆剥取り工具は、支持工具により電線に掛けられ、さらに別の操作工具により操作される。
このような操作工具として、先端にフックを有するバインド打ち器が提案されている（特許文献１）。 In such indirect hot wire construction, a wire coating stripping tool is used when performing stripping work of the wire coating. The electric wire covering stripping tool is hung on the electric wire by a support tool, and is further operated by another operation tool.
As such an operation tool, a bind hammer having a hook at the tip has been proposed (Patent Document 1).

図６は、従来の電線被覆の剥ぎ取り作業を説明する図である。
電線被覆剥取り工具であるハグラー５００は、電線２の被覆を剥取る電線被覆切断用刃５１０と、この電線被覆切断用刃５１０を電線２に当接させるためのねじ回し孔５２３を先端に備えた第１操作部５２０と、この第１操作部５２０とは略直交する方向に延びた支持部５３１の先端に操作孔５３２を有する第２操作部５３０とを備えている。
このハグラー５００は、電線把持器７００により電線に掛けられ支持され、さらに別の先端工具であるバインド打ち器８００により操作される。 FIG. 6 is a diagram for explaining a conventional stripping operation of the wire coating.
The Hagler 500, which is a wire coating stripping tool, includes a wire coating cutting blade 510 for stripping the coating of the wire 2 and a screw hole 523 for bringing the wire coating cutting blade 510 into contact with the wire 2 at the tip. The first operation unit 520 and a second operation unit 530 having an operation hole 532 at the tip of a support unit 531 extending in a direction substantially orthogonal to the first operation unit 520 are provided.
The Hagler 500 is supported by being hung on an electric wire by an electric wire gripper 700, and is further operated by a bind punch 800 which is another tip tool.

従来の電線被覆の剥ぎ取り作業について説明する。
ハグラー５００は、第２操作部５３０の支持部５３１が電線把持器７００に支持され、例えば、図示しない高所作業車の作業床に乗った作業者により、電線２に掛けられ支持される。続いて、作業者は、電線２を電線把持器７００で支持しつつ、バインド打ち器８００のフック８１０をハグラー５００のねじ回し孔５２３に引っ掛けて、バインド打ち器８００を回転させる。これにより、第１操作部５２０が回転し電線被覆切断用刃５１０を電線２の被覆に食い込ませる。次に、作業者は、第２操作部５３０の操作孔５３２にバインド打ち器８００のフック８１０を挿し入れ、ハグラー５００自体を電線２を中心に回転させる操作を行う。
このように、従来の電線被覆の剥取り作業では、電線被覆剥取り工具の他に、複数の先端工具を用いて取付け及び操作を行っていた。 The conventional stripping operation for the wire coating will be described.
The Hagler 500 is supported by the electric wire gripper 700 with the support portion 531 of the second operation unit 530 being hung on and supported by the electric wire 2 by, for example, an operator on a work floor of an aerial work vehicle (not shown). Subsequently, while supporting the electric wire 2 with the electric wire gripper 700, the operator hooks the hook 810 of the bind hammer 800 in the screw hole 523 of the Hagler 500 and rotates the bind hammer 800. As a result, the first operation unit 520 rotates and causes the wire sheath cutting blade 510 to bite into the sheath of the wire 2. Next, the operator inserts the hook 810 of the bind hammer 800 into the operation hole 532 of the second operation unit 530 and performs an operation of rotating the Hagler 500 itself around the electric wire 2.
Thus, in the conventional stripping operation of the wire coating, the mounting and operation are performed using a plurality of tip tools in addition to the wire coating stripping tool.

しかしながら、間接活線工事における電線被覆剥取り工具の操作は、高所作業車の作業床のような高所に設置された足場において行われる。よって、複数の先端工具を用いた操作は、電線被覆の剥取り作業の作業効率を落としていた。   However, the operation of the wire sheath stripping tool in the indirect hot wire construction is performed on a scaffold installed at a high place such as a work floor of an aerial work vehicle. Therefore, the operation using a plurality of tip tools has lowered the work efficiency of the stripping operation of the wire coating.

本発明は、間接活線工事における電線被覆剥取り工具の操作を１つの先端工具である把持工具で行うことで、電線被覆の剥取り作業の作業効率を向上することを目的とする。   An object of this invention is to improve the work efficiency of the stripping operation | work of an electric wire coating | cover by performing operation of the electric wire coating stripping tool in indirect hot wire construction with the holding tool which is one tip tool.

本発明の補助部材（例えば、補助部材１）は、
電線（例えば、電線２）の被覆を剥取る電線被覆切断用刃（例えば、電線被覆切断用刃５１０）を前記電線に当接させるねじ（例えば、ねじ５２１）の先端にねじ回し孔（例えば、ねじ回し孔５２３）が形成された平板状のねじ回し部（例えば、ねじ回し部５２２）を有する第１操作部（例えば、第１操作部５２０）と、前記第１操作部とは略直交する方向に延びた支持部（例えば、支持部５３１）の先端に操作孔（例えば、操作孔５３２）を有する第２操作部（例えば、第２操作部５３０）とを備える電線被覆剥取り工具（例えば、ハグラー５００）、及び支軸の先端に設けられた互いに対向する２つの口金（例えば、口金６１０）を近接又は離間させる把持工具（例えば、ヤットコ６００）を用いる間接活線工事において前記把持工具の先端に取付けられる補助部材であって、
２つの前記口金の先端にそれぞれ装着され、互いに対向する対向面（例えば、対向面１１１，１２１）をそれぞれ有する第１部材（例えば、第１部材１１）及び第２部材（例えば、第２部材１２）を備え、
前記第１部材及び前記第２部材は、前記対向面において、前記口金を近接させたときに、前記ねじ回し部を狭持し、
前記第１部材及び前記第２部材の前記対向面には、前記ねじ回し孔に係合する突起（例えば、突起１１２，１２２）がそれぞれ形成されている。 The auxiliary member of the present invention (for example, auxiliary member 1)
A screw hole (e.g., a screw 521) that abuts the wire coating cutting blade (e.g., the wire coating cutting blade 510) that strips the coating of the electric wire (e.g., the electric wire 2) on the wire. The first operation part (for example, the first operation part 520) having a flat screwdriver part (for example, the screwdriver part 522) in which the screwdriver hole 523 is formed and the first operation part are substantially orthogonal to each other. An electric wire covering stripping tool (for example, a second operation unit 530) having an operation hole (for example, operation hole 532) at the tip of a support portion (for example, support unit 531) extending in the direction (for example, , Hagler 500), and indirect hot-line work using a gripping tool (for example, Yatsuko 600) that moves two caps (for example, base 610) facing each other provided at the tip of the support shaft close to or away from each other. An auxiliary member attached to the end,
A first member (for example, the first member 11) and a second member (for example, the second member 12) that are respectively attached to the tips of the two caps and have opposing surfaces (for example, the opposing surfaces 111 and 121) facing each other. )
The first member and the second member sandwich the screwdriver when the base is brought close to the opposing surface,
On the opposing surfaces of the first member and the second member, projections (for example, projections 112 and 122) that engage with the screw hole are formed.

この発明によれば、電線被覆剥取り工具及び把持工具を用いる間接活線工事において把持工具の先端に取付けられる補助部材は、把持工具の２つの口金の先端にそれぞれ装着され、互いに対向する対向面をそれぞれ有する第１部材及び第２部材を備えた。そして、第１部材及び第２部材は、対向面において、電線被覆剥取り工具のねじ回し部を狭持する。また、これらの対向面には、電線被覆剥取り工具のねじ回し孔に係合する突起をそれぞれ形成した。   According to the present invention, the auxiliary members attached to the tips of the gripping tool in the indirect hot wire construction using the wire sheath stripping tool and the gripping tool are respectively mounted on the tips of the two caps of the gripping tool and face each other. The 1st member and the 2nd member which have respectively were provided. And a 1st member and a 2nd member pinch | screw the screwdriver part of an electric wire coating stripping tool in an opposing surface. Moreover, the protrusion which engages with the screwing hole of an electric wire coating stripping tool was formed in these opposing surfaces, respectively.

よって、本発明の補助部材を適用した電線被覆の剥ぎ取り作業は、以下のとおりである。
まず、第１部材及び第２部材を把持工具の２つの口金の先端にそれぞれ装着する。そして、把持工具の２つの口金を近接させ、電線被覆剥取り工具における第１操作部のねじ回し部を、第１部材及び第２部材の対向面で狭持する。このとき、これらの対向面に形成した突起は、ねじ回し部のねじ回し孔に係合させる。そして、把持工具の端部を持って、電線被覆剥取り工具を電線に掛ける。
次に、ねじ回し部を第１部材及び第２部材の対向面で狭持したまま、把持工具を回転させる。すると、ねじが回転して電線被覆切断用刃が電線に押しつけられ、電線被覆切断用刃が電線の被覆に食い込む。 Therefore, the stripping operation of the wire coating to which the auxiliary member of the present invention is applied is as follows.
First, the first member and the second member are respectively attached to the tips of the two caps of the gripping tool. Then, the two caps of the gripping tool are brought close to each other, and the screwing portion of the first operation portion in the wire covering stripping tool is held between the opposing surfaces of the first member and the second member. At this time, the protrusions formed on these opposing surfaces are engaged with the screw holes of the screw driver. Then, holding the end of the gripping tool, the wire covering stripping tool is hung on the wire.
Next, the gripping tool is rotated while the screwdriver is held between the opposing surfaces of the first member and the second member. Then, the screw rotates and the electric wire covering cutting blade is pressed against the electric wire, and the electric wire covering cutting blade bites into the electric wire covering.

このように、間接活線工事における電線被覆剥取り工具の操作において、電線把持器３００（図６参照）やバインド打ち器８００（図６参照）を用いることなく、補助部材を装着した把持工具だけで、電線被覆剥取り工具を電線に掛け、電線の被覆に電線被覆切断用刃を食い込ませることができる。
したがって、間接活線工事における電線被覆剥取り工具の操作を１つの先端工具である把持工具で行うことで、電線被覆の剥取り作業の作業効率を向上できる。 Thus, in the operation of the wire sheath stripping tool in the indirect hot wire construction, only the gripping tool equipped with the auxiliary member is used without using the wire gripper 300 (see FIG. 6) or the bind hammer 800 (see FIG. 6). Thus, the electric wire coating stripping tool can be hung on the electric wire, and the electric wire coating cutting blade can be bitten into the electric wire coating.
Therefore, the operation efficiency of the stripping operation of the wire sheath can be improved by performing the operation of the wire sheath stripping tool in the indirect hot wire construction with the gripping tool which is one tip tool.

また、前記第１部材又は前記第２部材（例えば、第１部材１１）には、前記対向面と略直交する側面（例えば、側面１１８）に、首部（例えば、首部１１６ａ）と前記首部の先端に形成され前記首部より外径が大きい頭部（例えば、頭部１１６ｂ）とから成る引っ掛け部（例えば、引っ掛け部１１６）が設けられ、
前記引っ掛け部の前記頭部は、その外径が前記ねじ回し孔及び前記操作孔の内径より小さく形成されている。 Further, the first member or the second member (for example, the first member 11) includes a neck portion (for example, the neck portion 116a) and a tip of the neck portion on a side surface (for example, the side surface 118) substantially orthogonal to the facing surface. And a hook part (for example, hook part 116) formed of a head (for example, head part 116b) having a larger outer diameter than the neck part is provided,
The head of the hook is formed so that the outer diameter thereof is smaller than the inner diameters of the screw hole and the operation hole.

この発明によれば、第１部材又は第２部材の側面に、首部と首部より外径が大きい頭部とから成る引っ掛け部を設けた。そして、引っ掛け部の頭部は、その外径がねじ回し孔及び操作孔の内径より小さく形成した。   According to this invention, the hook part which consists of a head part with a larger outer diameter than a neck part and a neck part was provided in the side surface of the 1st member or the 2nd member. And the head part of the hook part was formed so that the outer diameter was smaller than the inner diameter of the screwdriver hole and the operation hole.

よって、本発明の補助部材を適用した電線被覆の剥ぎ取り作業は、以下のとおりである。
電線被覆切断用刃を電線の被覆に食い込ませた後に、把持工具の口金を離間させ、第１部材及び第２部材の対向面で狭持していたねじ回し部を開放する。
次に、引っ掛け部の頭部を、電線被覆剥取り工具の第１操作部のねじ回し孔に挿通する。そして、把持工具を上方に押し上げる。すると、電線被覆剥取り工具は、電線を中心に回動し、第１操作部が上方に回動するとともに、第２操作部が下方に回動する。
次に、引っ掛け部の頭部を、第１操作部のねじ回し孔から抜き、第２操作部の操作孔に挿通する。そして、把持工具を上方に押し上げる。すると、電線被覆剥取り工具は、電線を中心に回動し、第２操作部が上方に回動するとともに、第１操作部が下方に回動する。このような電線被覆剥取り工具の操作により、電線の被覆を剥取ることができる。 Therefore, the stripping operation of the wire coating to which the auxiliary member of the present invention is applied is as follows.
After the electric wire covering cutting blade is bitten into the electric wire covering, the base of the gripping tool is separated, and the screwing portion held between the opposing surfaces of the first member and the second member is released.
Next, the head portion of the hook portion is inserted through the screw hole of the first operation portion of the wire covering stripping tool. Then, the gripping tool is pushed upward. Then, the wire sheath stripping tool rotates around the electric wire, the first operation unit rotates upward, and the second operation unit rotates downward.
Next, the head of the hooking part is removed from the screw hole of the first operation part and inserted into the operation hole of the second operation part. Then, the gripping tool is pushed upward. Then, the wire sheath stripping tool rotates around the electric wire, the second operation unit rotates upward, and the first operation unit rotates downward. By operating such a wire coating stripping tool, the wire coating can be stripped.

このように、間接活線工事における電線被覆剥取り工具の操作において、電線把持器３００（図６参照）やバインド打ち器８００（図６参照）を用いることなく、補助部材を装着した把持工具だけで、電線被覆剥取り工具を回転させ、電線の被覆を剥取ることができる。
したがって、間接活線工事における電線被覆剥取り工具の操作を１つの先端工具である把持工具で行うことで、電線被覆の剥取り作業の作業効率を向上できる。 Thus, in the operation of the wire sheath stripping tool in the indirect hot wire construction, only the gripping tool equipped with the auxiliary member is used without using the wire gripper 300 (see FIG. 6) or the bind hammer 800 (see FIG. 6). Then, the wire coating stripping tool can be rotated to strip the coating of the wires.
Therefore, the operation efficiency of the stripping operation of the wire sheath can be improved by performing the operation of the wire sheath stripping tool in the indirect hot wire construction with the gripping tool which is one tip tool.

また、前記第１部材及び前記第２部材には、基端に前記口金の先端が挿入される口金挿入部（例えば、口金挿入部１１３，１２３）が形成され、先端に前記ねじの一部を覆って係合するねじ係合部（例えば、ねじ係合部１１４，１２４）が形成されている。   The first member and the second member have a base insertion portion (for example, base insertion portion 113, 123) into which the tip of the base is inserted at the base end, and a part of the screw is attached to the tip. Screw engaging portions (for example, screw engaging portions 114 and 124) that cover and engage are formed.

この発明によれば、第１部材及び第２部材に、基端に口金の先端が挿入される口金挿入部を形成し、先端にねじの一部を覆って係合するねじ係合部を形成した。   According to the present invention, the first member and the second member are formed with the base insertion portion into which the distal end of the base is inserted at the proximal end, and the screw engagement portion that covers and engages a part of the screw with the distal end. did.

よって、把持工具の２つの口金を近接させ、電線被覆剥取り工具における第１操作部のねじ回し部を、第１部材及び第２部材の対向面で狭持するとともに、ねじの一部をねじ係合部で覆って係合できる。これにより、第１部材及び第２部材の対向面での狭持による圧迫力と、ねじ係合部での係合による支持力により、電線被覆剥取り工具を保持できるので、電線被覆剥取り工具を電線に掛ける作業が容易になる。   Therefore, the two bases of the gripping tool are brought close to each other, the screwing portion of the first operation portion in the wire coating stripping tool is held between the opposing surfaces of the first member and the second member, and a part of the screw is screwed. It can be covered and engaged with the engaging portion. As a result, the wire covering stripping tool can be held by the pressing force due to the holding of the first member and the second member on the opposing surfaces and the supporting force due to the engagement at the screw engaging portion. The work of hanging the wire on the wire becomes easy.

したがって、間接活線工事における電線被覆剥取り工具の操作を１つの先端工具である把持工具で行うことで、電線被覆の剥取り作業の作業効率をより向上できる。   Therefore, the operation efficiency of the wire sheath stripping operation can be further improved by performing the operation of the wire sheath stripping tool in the indirect hot wire construction with the gripping tool which is one tip tool.

本発明によれば、間接活線工事における電線被覆剥取り工具の操作を１つの先端工具である把持工具で行うことで、電線被覆の剥取り作業の作業効率を向上できる。   ADVANTAGE OF THE INVENTION According to this invention, the operation efficiency of the stripping | peeling work of an electric wire coating can be improved by performing operation of the electric wire coating stripping tool in indirect hot wire construction with the holding tool which is one tip tool.
