Description

本発明は、送電線を鉄塔に引き留める引留クランプに係り、より詳しくは、楔形引留クランプにより送電線を鉄塔に引留施工または撤去施工をするための、作業性に富んだ緊線金具に関する。 The present invention relates to anchor clamp detain the transmission lines tower, and more particularly, to an anchor construction or removal construction of transmission lines tower by the wedge-shaped anchor clamps,緊線gold again and again relates rich workability.

図4、5は、特許文献1に記載の従来の緊線用工具による架線法の説明図である。図4において、線条40を延線後、その線条40へ取り付けられている楔形クランプ20(この場合ジャンパー添付部24は取り外されているのが、一般的である)のストラップ26に設けられている工具連結孔へ、ストラップ26の連結金具連結孔に取り付けられている連結金具28との干渉を避ける湾曲部を有する緊線用工具50を軸を介して取り付ける。   4 and 5 are explanatory diagrams of the overhead wire method using the conventional wire tightening tool described in Patent Document 1. FIG. In FIG. 4, after the wire 40 is extended, it is provided on the strap 26 of the wedge-shaped clamp 20 attached to the wire 40 (in this case, the jumper attachment 24 is generally removed). A tightening tool 50 having a curved portion that avoids interference with the connecting fitting 28 attached to the connecting fitting connecting hole of the strap 26 is attached to the tool connecting hole.

その緊線用工具50の金車側連結孔に軸を介して緊線用金車30を連結すると共に、鉄塔側の直角クレビス60に軸を介して、緊線用金車30を連結し、これら2組の緊線用金車30にワイヤー32をかけ渡して、このワイヤー32を矢印Aのように引張ることにより緊線を行い、ライン側の金具類62を矢印Bのように移動させる。   The connecting wire wheel 30 is connected to the gold wheel side connecting hole of the connecting wire tool 50 via a shaft, and the connecting wire wheel 30 is connected to the right angle clevis 60 on the steel tower via the shaft, A wire 32 is passed over these two sets of wire tying wheels 30 and the wire 32 is pulled as shown by an arrow A to perform the wire connection, and the line-side metal fittings 62 are moved as shown by an arrow B.

図5において、ライン側の金具類62の端部とストラップ26と連結されている連結金具(クレビス金具)28とを軸により連結する。続いて、緊線用金車30に巻回されているワイヤー32を緩めて、線条40の張力をライン側の金具、耐張装置へ移動させる。そのとき楔形クランプの楔22の一方へジャンパー添付部24を取付け、それにジャンパー線40を添わせる。その後、緊線用工具50、緊線用金車30などを取り外せば緊線は完了する。   In FIG. 5, the end of the line-side metal fittings 62 and a connection metal fitting (clevis metal fitting) 28 connected to the strap 26 are connected by a shaft. Subsequently, the wire 32 wound around the wire rod 30 is loosened, and the tension of the wire 40 is moved to the line side metal fitting and tension device. At that time, the jumper attaching portion 24 is attached to one of the wedges 22 of the wedge-shaped clamp, and the jumper wire 40 is attached thereto. Thereafter, the tie line is completed by removing the tie line tool 50, the tie line wheel 30 and the like.

ところが、図5の従来の緊線用工具による架線法によると、緊線用金車30とライン側の金具類62とが重なり合って接触するため、引留施工または撤去施工が円滑に行われないという問題があった。   However, according to the overhead wire method using the conventional wire tightening tool of FIG. 5, the wire pulling wheel 30 and the metal fittings 62 on the line side are in contact with each other, so that the drawing construction or removal construction is not smoothly performed. There was a problem.

本発明の実施の形態について、図を用いて説明する。図1は、本発明による緊線金具の構造図である。図1a〜cにおいて、本発明の緊線金具100の一対の緊線金具本体10は、互いにテーパー部11を有している。また、当該テーパー部11は、固定部12により互いに対向して固定されている。   Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a structural diagram of a wire fitting according to the present invention. 1A to 1C, a pair of wire fitting main bodies 10 of the wire fitting 100 according to the present invention have tapered portions 11. In addition, the tapered portion 11 is fixed to be opposed to each other by a fixing portion 12.

一対の緊線金具本体10の一方の先端部はそれぞれ袴部10´を有し、先端部と袴部10´はクランプの連結板21(図2参照)に取り付けられるための第1の貫通穴13と第2の貫通穴14とをそれぞれ有している。第1の貫通穴13の穴径は、第2の貫通穴14の穴径より大きく穴開け加工されている。緊線金具本体10の他方の先端部は、セミ金車30(図3参照)が取り付けられるための第3の貫通穴17を有している。   One distal end of each of the pair of wire fitting main bodies 10 has a flange portion 10 ', and the distal end portion and the flange portion 10' are first through holes for being attached to the clamp connection plate 21 (see FIG. 2). 13 and a second through hole 14 respectively. The hole diameter of the first through hole 13 is larger than the hole diameter of the second through hole 14. The other tip end portion of the wire fitting main body 10 has a third through hole 17 for attaching a semi-metal wheel 30 (see FIG. 3).

図2は、本発明の緊線金具とクランプとの取付け穴の構造図である。図2において、クランプの連結板21は、緊線金具本体10を取り付けるための第1の貫通穴13の穴径、及び第2の貫通穴14の穴径と同じ穴径を、同じ間隔で有している。   FIG. 2 is a structural diagram of a mounting hole for the tight fitting and clamp according to the present invention. In FIG. 2, the connecting plate 21 of the clamp has the same hole diameter as the hole diameter of the first through hole 13 and the hole diameter of the second through hole 14 for attaching the tight fitting body 10 at the same interval. doing.

図3は、本発明の緊線金具とクランプとの取付け図である。緊線金具本体10はクランプの連結板21に、且つ、セミ金車30は緊線金具本体10に、それぞれ所定のピン15、16、18が各貫通穴13、14、17に挿入されることにより固定されている。また、各貫通穴13、14、17は、固定された状態において、ピン15、16がそれぞれ挿入された第1の貫通穴13及び第2の貫通穴14の中心を結ぶ直線と、ピン18が挿入された第3の貫通17の中心を通る前記直線に平行な直線との間隔Dが、セミ金車30の金車外径Rの1/2以上となるよう穴開け加工されている。 FIG. 3 is an attachment view of the tight fitting and clamp according to the present invention. The wire fitting body 10 is inserted into the connecting plate 21 of the clamp, the semi-metal wheel 30 is inserted into the wire fitting body 10, and predetermined pins 15, 16, 18 are inserted into the through holes 13, 14, 17, respectively. It is fixed by. In addition, the through holes 13, 14, 17 are fixed, and the straight line connecting the centers of the first through hole 13 and the second through hole 14 into which the pins 15, 16 are inserted, and the pin 18, Drilling is performed so that the distance D between the inserted through- hole 17 and the straight line parallel to the straight line passing through the center of the third through- hole 17 becomes 1/2 or more of the outer diameter R of the gold wheel 30 of the semi-gold wheel 30.

このように、第1の貫通穴13の穴径は、第2の貫通穴14の穴径より大きく穴開け加工されているため、ピンの差し違えによる取り付け誤りを解消することができ、作業性が向上する。また、第1の貫通穴13及び第2の貫通穴14の中心を結ぶ直線と、第3の貫通17の中心を通る前記直線に平行な直線との間隔Dが、セミ金車30の金車外径Rの1/2以上となるよう穴開け加工されて、セミ金車30がクランプの連結板22と干渉しないよう十分なクリアランスが確保されているため、図5における緊線用金車30とライン側の金具類62とが重なり合って接触し、引き留め施工または撤去施工が円滑に行われないという問題を解消することができる。これらのことから、楔形引留クランプにより送電線を鉄塔に引留施工または撤去施工をするための、作業性に富んだ緊線金具を提供することができる。 Thus, since the hole diameter of the first through hole 13 is larger than the hole diameter of the second through hole 14, it is possible to eliminate mounting errors due to incorrect pin insertion and workability. Will improve. The distance D between the straight line connecting the centers of the first through hole 13 and the second through hole 14 and the straight line passing through the center of the third through hole 17 is parallel to the straight line. Since the hole is machined so as to be ½ or more of the vehicle outer diameter R, and a sufficient clearance is secured so that the semi-gold wheel 30 does not interfere with the connecting plate 22 of the clamp, the tight wire wheel 30 in FIG. And the metal fittings 62 on the line side overlap and come into contact with each other, and the problem that the retaining construction or removal construction is not smoothly performed can be solved. From these, it is possible to provide a power transmission line by the wedge-shaped anchor clamps for the anchor construction or removal construction in tower,緊線gold instrument a rich workability.
