Description
【０００１】[0001]
本考案は、例えば架空送電線を延線するのに使用する電線延線具に関するもの である。 The present invention relates to a wire extension tool used for extending an overhead power transmission line, for example.
【０００２】[0002]
図３に示すように、一般に架空送電線の延線は、ドラム１０に巻かれた電線５ を引き出し該電線５の端末部に引留クランプ等のクランプ６を圧縮接続し、該ク ランプ６にワイヤロープ４を取り付けて巻取り機１１により巻取ることにより行 われる。 As shown in FIG. 3, generally, the extension of an overhead transmission line is performed by drawing out the electric wire 5 wound around a drum 10 and compressing and connecting a clamp 6 such as a retention clamp to the end portion of the electric wire 5. It is performed by attaching the rope 4 and winding it by the winder 11.
【０００３】 この際、電線５やワイヤロープ４が地面１２と接触しないように、鉄塔１３に 吊りワイヤを介して金車８を取付け、この金車８上をワイヤロープ４、クランプ ６、電線５がその順に通過して延線される。At this time, a gold wheel 8 is attached to the steel tower 13 via a hanging wire so that the wire 5 and the wire rope 4 do not come into contact with the ground 12, and the wire rope 4, the clamp 6, and the wire 5 are mounted on the gold wheel 8. Are passed in that order and are extended.
【０００４】 ところがクランプ６は所定長の長さを有するためこれが金車８上を通過する際 に延線張力により大きな曲げ荷重がかかり、これがクランプ６の変形およびけん 引力の増大の原因となっていた。However, since the clamp 6 has a predetermined length, when the clamp 6 passes over the gold wheel 8, a large bending load is applied due to the drawing wire tension, which causes deformation of the clamp 6 and an increase in traction force. It was
【０００５】 そこで、従来は特開昭５７−６５０９号に示す如く、電線端部に金車通過可能 の引留クランプを接続し、この引留クランプの端部の電線に電線延線具を取付け 、この電線延線具とワイヤロープを接続し、このワイヤロープをけん引すること により引留クランプにかかる曲げ荷重を緩和していた。In view of this, conventionally, as shown in Japanese Patent Laid-Open No. 57-6509, a wire clamp passing clamp is connected to the end of the wire, and a wire extension tool is attached to the wire at the end of the wire clamp. By connecting the wire extension tool and the wire rope and pulling the wire rope, the bending load applied to the strain clamp was alleviated.
【０００６】[0006]
しかしながら、上記のように電線延線具が引留クランプの端部に取付ける構造 であると、電線の最外層を締めこむようにして延線張力が伝達されるため前記電 線の最外層に負荷がかかり傷がついてしまう等の問題があった。また、上記の如 く延線張力を伝達するには、電線延線具の長手方向の寸法をある程度長くとる必 要があった。 However, if the wire drawing tool is attached to the end of the strain clamp as described above, the wire drawing tension is transmitted by tightening the outermost layer of the wire, and the load is applied to the outermost layer of the wire. There was a problem such as sticking. Further, in order to transmit the wire drawing tension as described above, it is necessary to lengthen the wire drawing tool in the longitudinal direction to some extent.
【０００７】[0007]
本考案は上述の事情に鑑みなされたものであり、延線時に電線の最外層に負荷 がかかることのない電線延線具を提供する。 The present invention has been made in view of the above circumstances, and provides an electric wire drawing tool in which a load is not applied to the outermost layer of the electric wire when the wire is drawn.
【０００８】[0008]
本考案の電線延線具は上述の目的を達成するため、電線端部に接続される引留 クランプの端部に取り付けられる電線延線具であって、内部に引留クランプと電 線の境界にできる段差に引っ掛かる取付段部を有することを特徴とする。 In order to achieve the above-mentioned object, the wire extension tool of the present invention is a wire extension tool that is attached to the end of a strain clamp connected to the end of the wire, and can be a boundary between the strain clamp and the power line inside. It is characterized in that it has an attachment step portion that is caught on a step.
【０００９】[0009]
本考案の電線延線具は、電線の端部に接続される引留クランプと電線の境界に できる段差に引っ掛かる取付段部を有するので、該段差によって延線張力が伝達 される。 Since the wire drawing tool of the present invention has the retention clamp connected to the end of the wire and the mounting step part that is caught on the step formed at the boundary of the wire, the wire tension is transmitted by the step.
【００１０】[0010]
本考案の実施例について図面を参照して詳細に説明する。図１に示されるよう に、本考案の電線延線具１は、２つ割りに分割されて成形されており、電線の端 部に設けられる引留クランプと電線の境界にできる段差に引っ掛かる取付段部Ａ を有している。 Embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, an electric wire extension tool 1 of the present invention is formed by being divided into two parts, and is attached to a step formed at the boundary between the retention clamp provided at the end of the electric wire and the electric wire. It has a part A 1.
【００１１】 また、電線延線具１には２つ割りに分割された電線延線具１を一体化するため の、ワイヤ用凹部２、駒用溝３が設けられており、延線時に電線の端部近傍に取 り付ける際、前記ワイヤ用凹部３にワイヤを巻き付け、駒用溝３に駒を組み込む ことにより一体化する。また、電線延線具１の延線方向端部にはワイヤロープ用 の穴２０が設けられている。Further, the wire drawing tool 1 is provided with a wire recess 2 and a piece groove 3 for integrating the wire drawing tool 1 divided into two parts. When the wire is mounted near the end of the wire, the wire is wound around the wire recess 3 and the piece is incorporated into the groove 3 for the piece to be integrated. A hole 20 for a wire rope is provided at the end of the wire drawing tool 1 in the drawing direction.
【００１２】 図２に示すように延線時には、２つ割りにされた前記電線延線具１が電線５と 引留クランプ６の接続部に取り付けられ、電線延線具１の延線方向端部の穴２０ にワイヤロープ４が取り付けられる。このとき電線延線具１の取付段部Ａが引留 めクランプ６と電線５の境界にできる段差に引っ掛かるようになっている。As shown in FIG. 2, at the time of wire drawing, the wire wire drawing tool 1 divided into two parts is attached to the connecting portion of the wire 5 and the retention clamp 6, and the wire drawing tool 1 has an end in the wire drawing direction. The wire rope 4 is attached to the hole 20 of the. At this time, the mounting step portion A of the wire drawing tool 1 is retained so as to be caught on the step formed at the boundary between the clamp 6 and the electric wire 5.
【００１３】 前記ワイヤロープ４をドラムで巻き取ることにより、前記段差で延線張力が伝 達され、吊りワイヤ７を介して設けられた金車８上をワイヤロープ４、電線延線 具１、電線５がその順に通過して延線が行われる。By winding the wire rope 4 around the drum, the wire tension is transmitted at the step, and the wire rope 4, the wire wire extension tool 1, and the wire wire extension tool 1, on the gold wheel 8 provided via the suspension wire 7. The electric wire 5 passes through in that order and is extended.
【００１４】 なお、電線延線具を一体化するには、ワイヤの巻き付け、駒の組み込みのいず れか一方でもよい。また、電線延線具は分割して成形するものを示したが一体成 形されたものでもよく、予め電線延線具とワイヤロープとを一体化しておくこと もできる。In order to integrate the wire drawing tool, one of winding a wire and assembling a piece may be used. Further, although the wire drawing tool is shown as being divided and molded, it may be integrally formed, and the wire drawing tool and the wire rope may be integrated in advance.
【００１５】[0015]
以上説明したように本考案の電線延線具は、電線の端部に設けられる引留クラ ンプと電線の境界にできる段差に引っ掛かる取付段部を有するので、該段差によ って延線張力が伝達される。したがって、電線の最外層に負荷がかからなくなり 前記最外層に傷がつく等の心配がない。また、段差を利用して張力が伝達される ので電線延線具の長手方向の寸法を小さくすることが可能となる。 As described above, the wire drawing tool of the present invention has the pulling clamp provided at the end of the wire and the mounting step portion that is caught by the step formed at the boundary of the wire. Transmitted. Therefore, no load is applied to the outermost layer of the electric wire, and there is no concern that the outermost layer is damaged. Further, since the tension is transmitted by utilizing the step, it is possible to reduce the lengthwise dimension of the wire drawing tool.
