【産業上の利用分野】[Industrial applications]

本考案はくさびを用いて電線をクランプ本体上に保持する型のくさび形引留ク ランプの改良に関るものである。 The present invention relates to an improvement of a wedge-shaped retractable clamp of a type in which an electric wire is held on a clamp body by using a wedge.

【0002】[0002]

【従来の技術】[Prior art]

以下図6〜図8に基いて公知例につき説明する。図6は正面図、図7は平面図 、図8はくさびの平面図である。くさび型引留クランプAのクランプ本体1はア ルミニウム合金等の金属よりなり、左右2つ割りで頂部の蝶番2で開閉可能に結 合されている。2つ割り両部材1aと1bの側部には細長板状の連結板3が複数個の ボルト4で固着されている。クランプ本体1の端部は図2で明らかな如く、平行 する2枚の板で構成された連結板3,3を固着する為巾広となっている。 Known examples will be described below with reference to FIGS. 6 is a front view, FIG. 7 is a plan view, and FIG. 8 is a plan view of the wedge. The clamp main body 1 of the wedge type detention clamp A is made of metal such as aluminum alloy, and is divided into left and right parts so that they can be opened and closed by a hinge 2 at the top. An elongated plate-like connecting plate 3 is fixed by a plurality of bolts 4 to the sides of the two split members 1a and 1b. As is apparent from FIG. 2, the end portion of the clamp body 1 is wide so as to fix the connecting plates 3 and 3 formed of two parallel plates.

【0003】 クランプ本体1内には上下1対のくさび5a,5bが挿入され、これら上下1対の くさび5aと5bはクランプ本体1の外部(図の左側)ボルト7aで一体にされている。 又下側のくさび5bはジャンパ−金具6とボルト7bで連結されている。上下1対の くさび5aと5bの互に対向する面は電線と等しい半径の円筒面よりなる電線係合面 となっている。電線係合面の反対側はV形凹部(図4の9a,9b参照)となり、こ れに対応しクランプ本体1a,1bの合せ部に形成されるV形凸部と凹凸係合し、上 下のくさび5a,5bが電線と共に引張られると、2つ割りのクランプ本体1も互に 接近し締め付けられる。A pair of upper and lower wedges 5a and 5b are inserted in the clamp body 1, and the pair of upper and lower wedges 5a and 5b are integrated by an external (left side in the figure) bolt 7a of the clamp body 1. The lower wedge 5b is connected to the jumper fitting 6 by bolts 7b. The pair of upper and lower wedges 5a and 5b facing each other is a wire engaging surface made of a cylindrical surface having the same radius as the wire. A V-shaped recess (see 9a and 9b in Fig. 4) is formed on the opposite side of the wire engaging surface. Corresponding to this, a V-shaped convex part formed at the mating part of the clamp bodies 1a and 1b is engaged and recessed to the upper side. When the lower wedges 5a and 5b are pulled together with the electric wire, the two-piece clamp body 1 is also brought close to each other and tightened.

【0004】 2つ割形状としたクランプ本体1は外側に張り出す1本のボルト4により連結 板3と連結される。クランプ本体1は上部を蝶番機構2により開閉可能とし、2 枚のくさび5a,5bをクランプ本体1内に挿入して電線aを引留めるようにしてい る。この引留クランプA′は電線aを回すため連結板3を長くし、またこの連結 板3はボルト部4で回動する構造となっている。しかもクランプ本体1と連結板 3との取付部は1本のボルト4(図7)で行うので、側方に大きく張り出し、金 車(図示なし)のスム−ズな通過が不可能であった。The clamp body 1 having a split shape is connected to the connecting plate 3 by a single bolt 4 projecting outward. The upper part of the clamp body 1 can be opened and closed by a hinge mechanism 2, and two wedges 5a and 5b are inserted into the clamp body 1 to hold the wire a. This retracting clamp A ′ has a structure in which the connecting plate 3 is lengthened in order to rotate the electric wire a, and the connecting plate 3 is rotated by the bolt portion 4. Moreover, since the mounting portion between the clamp body 1 and the connecting plate 3 is carried out by the single bolt 4 (Fig. 7), it is largely overhanged to the side, and smooth passage of the metal wheel (not shown) was impossible. .

【0005】 又引留クランプA′のくさび押込作業を高い塔上で行わねばならず、極めて熟 練を要する危険な作業が必要であった。Further, the wedge pushing operation of the detention clamp A'has to be performed on a high tower, which requires a dangerous operation requiring extremely high maturity.

【実施例】【Example】

以下図1〜図6に基いて説明する。図1は正面図、図2は平面図、図3は底面 図、図4は左側面図、そして図5は右側面図である。 くさび型引留クランプAのクランプ本体1はアルミニウム合金等の金属よりな り、左右2つ割りで頂部の蝶番2で側方に開閉可能に結合されている。2つ割り 両部材1aと1bの側部には細長板材よりなる連結板3が複数個の小サイズのボルト 4で固着されている。クランプ本体1は図2で明らかな如く、平面視で巾狭の長 方形をなし、これの側部に固着された左右1対の連結板3,3もクランプ本体1 の巾wと略等しく平行に取付けられている。 Hereinafter, description will be given with reference to FIGS. 1 is a front view, FIG. 2 is a plan view, FIG. 3 is a bottom view, FIG. 4 is a left side view, and FIG. 5 is a right side view. The clamp main body 1 of the wedge type detention clamp A is made of a metal such as an aluminum alloy, and is divided into left and right parts and is hingedly connected to the side with a hinge 2 at the top. A connecting plate 3 made of an elongated plate member is fixed to the side portions of the two split members 1a and 1b by a plurality of small bolts 4. As shown in FIG. 2, the clamp body 1 has a narrow rectangular shape in a plan view, and the pair of left and right connecting plates 3 and 3 fixed to the sides of the clamp body 1 are substantially equal to and parallel to the width w of the clamp body 1. Installed on.

【0009】 クランプ本体1内には上下1対のくさび5a,5bが挿入され、これら上下1対の くさび5aと5bはクランプ本体1の外部(図の右側)でジャンパ−金具6とボルト 7bで連結されている。上下1対のくさび5aと5bの互に対向する面は電線aと等し い半径の円筒面よりなる電線係合面8a,8bとなっている。電線係合面の反対側は V形凹部9a,9bとなり、これに対応しクランプ本体1a,1bの合せ部に形成される V形凸部と凹凸係合し、上下のくさび5a,5bが電線aと共に引張られると、2つ 割りのクランプ本体1も互に接近し締め付けられる。A pair of upper and lower wedges 5a and 5b are inserted in the clamp body 1, and these pair of upper and lower wedges 5a and 5b are provided outside the clamp body 1 (on the right side in the figure) by a jumper metal fitting 6 and a bolt 7b. It is connected. The surfaces of the pair of upper and lower wedges 5a and 5b facing each other are electric wire engaging surfaces 8a and 8b made of cylindrical surfaces having the same radius as the electric wire a. On the opposite side of the wire engaging surface are V-shaped recesses 9a, 9b, which correspondingly engage with the V-shaped projections formed at the mating parts of the clamp bodies 1a, 1b, and the upper and lower wedges 5a, 5b When pulled together with a, the two clamp bodies 1 also approach each other and are tightened.

【0010】 ジャンパ−金具6は図1に示すごとく円弧状をなし、ジャンパ−部電線aが嵌 まるよう断面が電線aと同径で半円形をなし、一端には上下1対のくさび5aと5b をボルト7aで固着し、他端にジャンパ−部電線aの電線押え10を備えている。As shown in FIG. 1, the jumper metal member 6 has an arc shape, a cross section of which has the same diameter as the electric wire a and a semicircular shape so that the electric wire a of the jumper portion can be fitted, and a pair of upper and lower wedges 5a is provided at one end. 5b is fixed with a bolt 7a, and a wire retainer 10 for the jumper portion electric wire a is provided at the other end.

【0011】 (引留クランプの取付) 引留クランプの取付けは地上のドラム場で計尺された電線aの所定個所におい てクランプ本体1内で電線aを1対のくさび5a,5bの間に挿入して取付けた状態 にし、図示しない保護金具を装着して、延線する。その後塔上で緊線したのち、 保護金具を取り外し、連結金具への取付けを行い、作業完了となる。連結金具で がいし連と連結したのち、ジャンパ−金具6を取付け、ジャンパ−部電線aの取 付けを行い、ジャンパ−線の成形をする。(Installation of Tow Clamp) To install the tow clamp, insert the wire a between the pair of wedges 5a and 5b in the clamp body 1 at a predetermined position of the wire a measured on the ground drum field. Installed, attach protective metal fittings (not shown), and then extend the wire. After tightening the wires on the tower, remove the protective fittings and attach them to the connecting fittings to complete the work. After connecting to the insulator string with the connecting metal fitting, attach the jumper metal fitting 6, attach the jumper part electric wire a, and form the jumper wire.

【0012】[0012]

【効果】【effect】

クランプ本体と連結板を数本のボルトにより固着したのでクランプ横方向の幅 寸法を狭くすることができ、連結板が短かくなったので、クランプ本体と連結部 が一体となっても延線時の直径600mmアルミ金車内を通過可能となった。また 回動部はがいし連と結合される連結金具(図示せず)を使用すればよい。 このようなクランプであるから、クランプ全体を覆う楕円形を有した金属製の 保護金具を装着することによりクランプ本体と連結部の曲げを防ぎつつ、金車内 をスム−ズに通過させることができる。 かくして地上で予め組立てたのち、塔上でのくさび押込み作業がなくなるので 完全カムアロングレス工法が採用でき、安全かつ能率的な作業が可能となった。 Since the clamp body and connecting plate are fixed with several bolts, the lateral width of the clamp can be made narrower, and the connecting plate has become shorter. It has become possible to pass inside a 600 mm diameter aluminum metal car. Further, the rotating portion may use a connecting fitting (not shown) that is connected to the insulator string. With such a clamp, it is possible to smoothly pass through the inside of the gold wheel while preventing bending of the clamp body and the connecting part by mounting a metal protective metal fitting having an elliptical shape that covers the entire clamp. . Thus, after pre-assembling on the ground, the wedge pushing work on the tower is eliminated, so the complete cam along-less construction method can be adopted, and safe and efficient work is possible.
