【考案の詳細な説明】
送電線の落雷被害を避けるため、鉄塔最上部に於て、送
電線と平行に架空地線、略して地線と呼ばれるものを張
設することが公知であり、これが鉄塔を通じて接地され
る。[Detailed explanation of the invention] In order to avoid lightning damage to power transmission lines, it is well known to install an overhead ground wire (abbreviated as a ground wire) in parallel to the power transmission line at the top of a steel tower. Grounded through the steel tower.
送電線には主として鋼心アルミ撚線を用いるが、地線に
は主として銅撚線、アルミ撚線等同一材質素線から成る
撚線を用いる。Steel-core aluminum stranded wires are mainly used for power transmission lines, while stranded wires made of the same material wires, such as copper stranded wires and aluminum stranded wires, are mainly used for ground wires.
他にこれに準するものとしてアルミ被覆した鋼撚線や亜
鉛鍍金した銅撚線等も用いるが、倒れにしても地線は送
電線とは異り、小径である。Similar wires such as aluminum-coated steel stranded wire or zinc-plated copper stranded wire are also used, but even if they fall down, ground wires have a small diameter unlike power transmission lines.
本考案は延線作業のため地線を引留める延線クランプに
関するもので、全体を小型化し、しかも引留を確実にす
ることを目的としたものである。The present invention relates to a wire extension clamp for holding ground wires in place for wire extension work, and its purpose is to reduce the overall size and to ensure reliable holding.
図面についてその実施例を説明する。Examples will be described with reference to the drawings.
地線の延線作業は送電線の場合と異らない。Ground line extension work is no different from that for power transmission lines.
即ち延線ワイヤＷの終端にランニングボードＢの一端を
接続し、ランニングボードの他端には延線クランプＣを
介し、地線Ｅの始端を引止める。That is, one end of the running board B is connected to the terminal end of the running wire W, and the starting end of the ground wire E is held at the other end of the running board via the running board clamp C.
以上は公知のことである。The above is publicly known.
次に本考案の延線クランプＣはクレビス金具１と、円筒
形スリーブ２と、保護カバ３とから成る。Next, the wire extension clamp C of the present invention consists of a clevis fitting 1, a cylindrical sleeve 2, and a protective cover 3.
クレビス金具１は一端部がクレビスに形成され、附設ボ
ルト４によってワイヤＷを係止可能としである。The clevis fitting 1 has one end formed as a clevis, and is capable of locking the wire W with an attached bolt 4.
クレビス金具１の他端には有底孔１ａが穿たれ、その内
外径にねじが設けである。A bottomed hole 1a is bored at the other end of the clevis fitting 1, and screws are provided on the inner and outer diameters of the hole 1a.
スリーブ２は一端部にクレビス金具の内径ねじと螺合可
能なねじが刻まれ、他端部には軸線方向有底孔が穿たれ
地線Ｅを挿入圧着可能としである。One end of the sleeve 2 has a thread that can be screwed into the inner diameter thread of the clevis fitting, and the other end has a bottomed hole in the axial direction so that the ground wire E can be inserted and crimped therein.
前記の如く地線Ｅは銅撚線、アルミ撚線その他から構成
されるので、スリーブ２はこれを圧着するに適したもの
として鋼、アルミ、銅等から適当材質のものを選ぶ。As mentioned above, since the ground wire E is made of stranded copper wire, stranded aluminum wire, etc., the sleeve 2 is made of an appropriate material such as steel, aluminum, copper, etc., which is suitable for crimping the ground wire.
保護カバ３はスリーブ２へ被挿可能な円筒体で、一端部
内径にクレビス金具の外径ねじと螺合可能なねじを設け
である。The protective cover 3 is a cylindrical body that can be inserted into the sleeve 2, and has a thread on the inner diameter of one end that can be screwed into the outer diameter thread of the clevis fitting.
以上のように構成された本考案では、まずスリーブへ地
線Ｅを挿入圧着した後、スリーブをクレビス金具へ螺合
固着する。In the present invention configured as described above, first, the ground wire E is inserted and crimped into the sleeve, and then the sleeve is screwed and fixed to the clevis fitting.
続いてあらかじめ地線外周へ被挿しておいた保護カバ３
の位置をずらせ、クレビス金具の外径ねじへ螺合固着す
る。Next, protect cover 3 that has been inserted into the outer circumference of the ground wire in advance.
Shift the position of and screw onto the outer diameter thread of the clevis fitting.
このようにして地線を引留め、延線作業を行い、そのあ
とクレビス金具と保護カバは取外して再使用する。In this way, the ground wire is held in place and the wire extension work is carried out, after which the clevis fitting and protective cover are removed and reused.
以上では送電線と地線とを区別し、地線に限定して述べ
たが、送電線（鋼心アルミ撚線）でも、小径のものは、
本考案がそのまま適用可能なことは自明である。In the above, we have distinguished between power transmission lines and ground wires, and have limited our discussion to ground wires, but even power transmission lines (steel-core aluminum stranded wires) with small diameters
It is obvious that the present invention can be applied as is.
従来は一端に勾配孔を有するスリーフヘ他端から地線端
部を挿入し、勾配孔側から地線端面中央へくさびを叩き
こんで撚線し、撚線部と勾配孔とを係合させ、この端部
をクレビス金具で引留める構造によっていた。Conventionally, a ground wire end is inserted from the other end into a sleeve having a slope hole at one end, a wedge is driven into the center of the ground wire end face from the slope hole side to twist the wire, and the twisted wire portion and the slope hole are engaged. This end was held in place with a clevis fitting.
即ち地線は主としてくさび作用で引留められるので、く
さびが短いと引留が不確かになり、長いとクランプ全長
も長くなって金車乗りこえが困難になる。That is, the ground wire is mainly held in place by a wedge action, so if the wedge is short, the holding will be uncertain, and if the wedge is long, the overall length of the clamp will also be long, making it difficult to cross over the metal wheel.
もともとくさび打込みは煩わしい作業である。Driving wedges is originally a troublesome task.
またスリーブは地線の張力と金車通過時の曲げ応力の双
方に対応せねばならぬので、不自然に肉厚のものを必要
とする。Further, since the sleeve must cope with both the tension of the ground wire and the bending stress when passing through the metal wheel, it needs to be unnaturally thick.
これに対し本考案は張力がくさび作用より強力な圧縮に
よっておこなう。In contrast, in the present invention, the tension is achieved by compression, which is stronger than the wedge action.
スリーブは地線の張力に耐えるにたりる肉厚とし、金車
通過時の曲げ力は保護カバに負担させる。The sleeve is thick enough to withstand the tension of the ground wire, and the bending force when passing through the metal wheel is borne by the protective cover.
よって、長さが短かくてすみ、全体を小型化して確実な
引留が行える。Therefore, the length can be shortened, and the overall size can be reduced to ensure reliable anchorage.
