Description

この発明は、洞道壁面等に設置されるトラフ内に複数の電力ケーブルを纏めて固定するクリート、及びそのクリートの電力ケーブル挟持片と前記電力ケーブルの間に介在される支持ゴムに関する。   The present invention relates to a cleat for collectively fixing a plurality of power cables in a trough installed on a wall surface of a cave, and a support rubber interposed between the power cable holding piece of the cleat and the power cable.

この種の電力ケーブル固定用のクリートは、図１３に示すように、地下洞道壁面等に設置されるＦＲＰ（繊維強化プラスチック）トラフＡ内にケーブルＰの所要長さ、例えば３．５ｍ以下の間隔に設けられてケーブルＰを支持するものであり（図１参照）、対の挟持片１、１の間に弾性材からなる支持ゴム２を介在して電力ケーブルＰを挟み、その対の挟持片１、１をねじ止めした構成が一般的であり、その対の挟持片１、１の一方をＦＲＰトラフＡ内に固定する。そのとき、通常、その対の挟持片１，１による電力ケーブルＰの挟持を複数段に行われる（特許文献１参照）。
特開２００４−１２０８３６号公報 As shown in FIG. 13, this type of power cable fixing cleat has a required length of the cable P in the FRP (fiber reinforced plastic) trough A installed on the wall surface of the underground cavern, etc., for example, 3.5 m or less. The cable P is provided at intervals and supports the cable P (see FIG. 1). The power cable P is sandwiched between the pair of sandwiching pieces 1 and 1 with a support rubber 2 made of an elastic material interposed therebetween. A configuration in which the pieces 1 and 1 are screwed is common, and one of the pair of sandwiching pieces 1 and 1 is fixed in the FRP trough A. At that time, the electric power cable P is normally held by the pair of holding pieces 1 and 1 in a plurality of stages (see Patent Document 1).
Japanese Patent Laid-Open No. 2004-12083

このクリートにおいて、上記対の挟持片１、１のねじ止めは、その対の挟持片１、１の両端にボルト３を挿通して締結している（特許文献１参照）。
そのボルト３による締結時、十分な締結力を得るために、対の挟持片１、１のそのねじ込み部に隙間ｔを設けて、その締付け力が電力ケーブルＰ及び支持ゴム２に確実に及ぶようにしている。このため、その締結力は、５００ｋｇ-ｃｍにもなることがある。
一方、高電圧電力ケーブルＰには、ケーブル内部に絶縁油を封入した仕様のものがあり、このケーブルＰはその所定内圧が２〜５ｋｇ／ｃｍ２程度とされている。 In this cleat, the screwing of the pair of sandwiching pieces 1 and 1 is fastened by inserting bolts 3 at both ends of the pair of sandwiching pieces 1 and 1 (see Patent Document 1).
In order to obtain a sufficient fastening force at the time of fastening with the bolt 3, a clearance t is provided in the screwed portion of the pair of sandwiching pieces 1, 1 so that the fastening force reaches the power cable P and the support rubber 2 reliably. I have to. For this reason, the fastening force may be as high as 500 kg-cm.
On the other hand, some high-voltage power cables P have specifications in which insulating oil is sealed inside the cables, and the cable P has a predetermined internal pressure of about 2 to 5 kg / cm 2 .

このような実情の下、対の挟持片１、１を高トルク（必要以上のトルク）で締付けると、ケーブルＰに異常な内圧が発生し、絶縁油が漏洩する等の不具合が生じる場合があった。
その高トルクの締結による不都合をなくすため、上記ボルトによる締結をばねを介して行い、そのばねの緩衝により、高トルクの締結を防止した技術がある（特許文献１ 図１参照）。
しかし、上記ばねによる緩衝は、その構造が繁雑となり、クリートのコスト上昇を招いている。 Under such circumstances, if the pair of clamping pieces 1 and 1 are tightened with a high torque (torque more than necessary), abnormal internal pressure may occur in the cable P, leading to problems such as leakage of insulating oil. It was.
In order to eliminate the inconvenience caused by the high torque fastening, there is a technique in which the fastening by the bolt is performed via a spring and the high torque fastening is prevented by buffering the spring (see Patent Document 1 in FIG. 1).
However, the structure of the buffer by the spring is complicated, which causes an increase in cleat cost.

この発明は、上記ばねによる緩衝以外の手段により、ケーブルＰの締め過ぎを防止することを課題とする。   An object of the present invention is to prevent the cable P from being overtightened by means other than the buffering by the spring.

上記課題を達成するために、この発明は、まず、支持ゴムの電力ケーブルとの接触面に滑り止め用突起を設けたのである。
電力ケーブルの滑り止めが行われれば、支持ゴムによる電力ケーブルの支持力が増すため、ボルトによる締結力を抑えることができる（締結力を小さくしても良い）。
つぎに、この発明は、電力ケーブルを挟持する対の挟持片が当たったねじ止め状態（それ以上ねじ込めない状態）で、その電力ケーブルの最適な支持固定がされるようにしたのである。
その最適な支持固定度合は、対の挟持片の挟持力とボルトによる締付力とを実験などにより、適宜に選定して、その締付力によりその電力ケーブルが支障なく支持固定されるようにする。 In order to achieve the above object, the present invention first provides an anti-slip protrusion on the contact surface of the support rubber with the power cable.
If the power cable is prevented from slipping, the supporting force of the power cable by the supporting rubber is increased, so that the fastening force by the bolt can be suppressed (the fastening force may be reduced).
Next, according to the present invention, the power cable is optimally supported and fixed in a screwed state in which the pair of holding pieces for holding the power cable is in contact (a state where the power cable cannot be screwed any further).
The optimum degree of support and fixing is to select the clamping force of the pair of clamping pieces and the clamping force by bolts appropriately through experiments, etc., so that the power cable can be supported and fixed without hindrance by the clamping force. To do.

この発明は、支持ゴムの支持力アップを図ると共に、対の挟持片を突き合わせて所要以上の締結力が働かないようにしたので、安価な構造でもって、ケーブルＰの締め過ぎを防止でき、例えば、ケーブル内部に絶縁油を封入した高電圧電力ケーブルでのその絶縁油の漏洩が生じることもなくなる。   In the present invention, the supporting force of the supporting rubber is increased, and the pair of clamping pieces are abutted against each other so that an excessive fastening force does not work. Therefore, the cable P can be prevented from being overtightened with an inexpensive structure, for example, In addition, leakage of the insulating oil in the high voltage power cable in which the insulating oil is sealed inside the cable does not occur.

この発明の一実施形態としては、洞道壁面等に設置されるトラフ内に複数の電力ケーブルを纏めて固定するクリートの、電力ケーブル挟持片と前記電力ケーブルの間に介在される支持ゴムにおいて、その電力ケーブルとの接触面に滑り止め用突起を設けた構成を採用することができる。
その突起は、電力ケーブル接触面に粒状に配置してもよいが、電力ケーブルの周方向に長い突条とすることもできる。 As one embodiment of the present invention, in the support rubber that is interposed between the power cable holding piece and the power cable of the cleat that collectively fixes a plurality of power cables in the trough installed on the wall surface of the cave, etc. A configuration in which a non-slip protrusion is provided on the contact surface with the power cable can be employed.
The protrusions may be arranged in a granular form on the power cable contact surface, but can also be long protrusions in the circumferential direction of the power cable.

また、その突条の横断面は、三角形状とすることができ、そのとき、その突条を電力ケーブルの長さ方向に複数条設けて、その複数の突条を２つの群に分け、その両突条群の前記断面三角形状をその頂点が底辺の中点からそれぞれ反対方向に傾いたものとして異ならせたものとすると良い。
このようにすれば、その傾斜の異なるそれぞれの突条が、電力ケーブルが前記反対方向に対してその反対方向に移動しようとした際、頂点が底辺の中点からずれて傾いた断面三角形状のそれぞれの突条群がその移動方向に有効な抵抗力を発揮してその移動を阻止する。
なお、突起群の二分けは、電力ケーブルとの接触面のその電力ケーブルの長さ方向の中心線を境にして分けなくても、断面三角形状の異なる突条が接触面の全域に散らばっていてもよく、また、電力ケーブルの長さ方向に、一方向に傾く突起と他方に傾く突起を交互に配置するようにすることもできる。 Further, the cross section of the ridge can be triangular, and at that time, a plurality of ridges are provided in the length direction of the power cable, the plurality of ridges are divided into two groups, and It is preferable that the above-described triangular shapes of the two protrusion groups are different from each other as the apexes thereof are inclined in opposite directions from the midpoint of the base.
In this way, each of the protrusions having different inclinations has a triangular cross section whose apex is inclined and deviated from the midpoint of the bottom when the power cable tries to move in the opposite direction with respect to the opposite direction. Each ridge group exhibits an effective resistance force in the moving direction to prevent the movement.
In addition, even if the protrusion group is not divided into two with the center line in the length direction of the power cable in the contact surface with the power cable as a boundary, different protrusions having a triangular cross section are scattered over the entire contact surface. Alternatively, protrusions inclined in one direction and protrusions inclined in the other direction can be alternately arranged in the length direction of the power cable.

支持ゴムの上記電力ケーブル挟持片との接触面とその電力ケーブル挟持片の支持ゴムとの接触面には、相互に嵌り合う凹凸を設け、その凹凸の嵌り合いにより、挟持片に対し支持ゴムが移動し難いようにすることが好ましい。   The contact surface of the support rubber with the power cable sandwiching piece and the contact surface of the power cable sandwiching piece with the support rubber are provided with recesses and projections that fit each other. It is preferable to make it difficult to move.

これらの支持ゴムは、その突起により電力ケーブルの支持力が増すため、電力ケーブルクリートの電力ケーブルと挟持片の間に介在し、クリートの対の挟持片が当たったねじ止め状態でその電力ケーブルが最適な状態で支持固定されている構成とすることができる。
このとき、クリートをＦＲＰ製とすれば、従来のアルミニウム製に比べて安価であり、また、軽量等から取り扱いも容易である。 Since these supporting rubbers increase the supporting power of the power cable due to the protrusions, these rubbers are interposed between the power cable and the sandwiching piece of the power cable cleat, and the power cable is in a screwed state where the pair of cleats are in contact with each other. It can be set as the structure fixedly supported in the optimal state.
At this time, if the cleat is made of FRP, it is cheaper than the conventional aluminum and is easy to handle because of its light weight.

図１〜図２０に一実施例を示し、この実施例は、洞道壁面に設置されるＦＲＰトラフＡ内に電力ケーブルＰ及び通信ケーブルＴを配設したものであり、電力ケーブルＰはＦＲＰ製クリート１０を介してそのトラフＡの底壁に固定され、通信ケーブルＴ等は棚に載置されて適宜間隔で適宜な手段によって固定されている。上下の電力ケーブルＰの間には水冷管Ｓが設けられ、この水冷管Ｓに水を流すことにより、電力ケーブルＰを冷却してその昇温を抑制するが、この水冷管Ｓの数は任意であり、例えば、図１の左右の一方のみ、全く設けない（省略する）等とすることができる。   FIG. 1 to FIG. 20 show an embodiment. In this embodiment, a power cable P and a communication cable T are arranged in an FRP trough A installed on a wall surface of a cave, and the power cable P is made of FRP. It is fixed to the bottom wall of the trough A through the cleat 10, and the communication cable T and the like are placed on a shelf and fixed by appropriate means at appropriate intervals. A water-cooled pipe S is provided between the upper and lower power cables P, and by flowing water through the water-cooled pipe S, the power cable P is cooled and its temperature rise is suppressed. The number of the water-cooled pipes S is arbitrary. For example, only one of the left and right in FIG. 1 may not be provided (omitted).

この実施例のクリート１０は、電力ケーブルＰ及び水冷管Ｓを３段にして支持固定するものであり、ＦＲＰ製の４個の挟持片１１ａ、１１ｂ、１１ｃ、１１ｄ（総称符号：１１）からなり、その上下の対の挟持片１１ａと１１ｂ、１１ｂと１１ｃ、１１ｃと１１ｄにより、電力ケーブルＰ及び水冷管Ｓを挟持固定する。この実施例のクリート１０には、その各挟持片１１と電力ケーブルＰ及び水冷管Ｓの間に支持ゴム１２が介在され、その上下の対となる挟持片１１、１１はボルト１３により固定される（一体化される）。   The cleat 10 of this embodiment is configured to support and fix the power cable P and the water-cooled pipe S in three stages, and is composed of four FRP clamping pieces 11a, 11b, 11c, and 11d (generic symbol: 11). The power cable P and the water-cooled tube S are clamped and fixed by the upper and lower pairs of clamping pieces 11a and 11b, 11b and 11c, and 11c and 11d. In the cleat 10 of this embodiment, a support rubber 12 is interposed between each of the holding pieces 11 and the power cable P and the water-cooled tube S, and the upper and lower pairs of holding pieces 11 and 11 are fixed by bolts 13. (Integrated).

支持ゴム１２は、電力ケーブルＰ及び水冷管Ｓの大小に応じて大小２種類のもの（１２ａ、１２ｂ）であり、その両者１２ａ、１２ｂも、図８、図９に示すように、円弧状をして、その電力ケーブルＰ及び水冷管Ｓとの接触面（内側面）に滑り止め用突起１４を設けている。この支持ゴム１２は、同一形状のものを上下に対にして電力ケーブルＰ及び水冷管Ｓに当てがう（図２参照）。水冷管Ｓへの支持ゴム１２は上下のどちらか一方でも良い。
突起１４は、電力ケーブルＰ及び水冷管Ｓの周方向に長い突条となって、その横断面が三角形状となっているとともに電力ケーブルＰ及び水冷管Ｓの長さ方向に複数条設けられている。
その複数の突条１４は、電力ケーブルＰ及び水冷管Ｓとの接触面のその電力ケーブルＰ及び水冷管Ｓの長さ方向の中心線を境にして異なる態様に２分類されており、その２分類された両突条１４群は、上記断面三角形状をその頂点が底辺の中点からそれぞれ反対方向に傾いた異なるものとなっている（図８（ｅ）、図９（ｅ）参照）。 The support rubber 12 is of two types (12a and 12b) depending on the size of the power cable P and the water-cooled pipe S. Both of the support rubbers 12a and 12b have an arc shape as shown in FIGS. Then, a non-slip protrusion 14 is provided on the contact surface (inner surface) with the power cable P and the water-cooled pipe S. The support rubber 12 is applied to the power cable P and the water-cooled tube S with the same shape paired up and down (see FIG. 2). The support rubber 12 for the water-cooled tube S may be either the upper or lower side.
The protrusions 14 are long ridges in the circumferential direction of the power cable P and the water cooling pipe S, and the cross section thereof is triangular, and a plurality of ridges 14 are provided in the length direction of the power cable P and the water cooling pipe S. Yes.
The plurality of protrusions 14 are classified into two different modes with the center line in the length direction of the power cable P and the water cooling pipe S at the contact surface between the power cable P and the water cooling pipe S as a boundary. The two groups of ridges 14 thus classified are different from each other in that the cross-sectional triangle shape has its apex inclined in the opposite direction from the midpoint of the base (see FIGS. 8 (e) and 9 (e)).

また、支持ゴム１２の電力ケーブル挟持片１１との接触面には、その電力ケーブル挟持片１１の凹部１５に嵌る凸部１６が形成されており、この凸部１６が凹部１５に嵌ることにより、支持ゴム１２が挟持片１１に対し移動しなくなる。凹部１５を支持ゴム１２側、凸部１６を挟持片１１側に設けることもできる。   Further, on the contact surface of the support rubber 12 with the power cable holding piece 11, a convex portion 16 that fits into the concave portion 15 of the power cable holding piece 11 is formed, and by fitting this convex portion 16 into the concave portion 15, The support rubber 12 does not move relative to the sandwiching piece 11. The concave portion 15 can be provided on the support rubber 12 side, and the convex portion 16 can be provided on the clamping piece 11 side.

クリート１０は、電力ケーブルＰの長さ方向に適宜間隔（例えば、従来と同様に、３．５ｍ以下の間隔）に設けて、電力ケーブルＰ及び水冷管ＳをトラフＡに支持固定し、その各クリート１０の間の各電力ケーブルＰ及び水冷管Ｓの間にはＦＲＰ製の中間スペーサ２０（２０ａ、２０ｂ、２０ｃ）を介設する。その中間スペーサ２０は、図１０〜図１２に示す３種類のものからなる。   The cleat 10 is provided at an appropriate interval in the length direction of the power cable P (for example, an interval of 3.5 m or less as in the conventional case), and the power cable P and the water-cooled pipe S are supported and fixed to the trough A. An intermediate spacer 20 (20a, 20b, 20c) made of FRP is interposed between each power cable P and the water cooling pipe S between the cleats 10. The intermediate spacer 20 consists of three types shown in FIGS.

そのクリート１０の各挟持片１１をボルト１３により締め付ける際、上下対の挟持片１１、１１が当たったねじ止め状態（図２の状態）で、その電力ケーブルＰが最適な状態で支持固定される。このため、電力ケーブルＰ及び水冷管Ｓが必要以上に締付けられることもなく（過大なトルクがかかることもなく）、その電力ケーブルＰが高電圧のもので、絶縁油が封入されてあっても、その絶縁油が漏洩することもない。
また、クリート１０は、ＦＲＰ製であって、従来のアルミニウム製に比べて安価であり、さらに、軽量等から取り扱いも容易である。
トラフＡ内にはコンクリートを充填しても良い。 When each clasp piece 11 of the cleat 10 is tightened with the bolt 13, the power cable P is supported and fixed in an optimal state in a screwed state (the state shown in FIG. 2) where the pair of upper and lower sandwiching pieces 11 and 11 are in contact. . For this reason, the power cable P and the water-cooled pipe S are not tightened more than necessary (no excessive torque is applied), and the power cable P is of a high voltage and is filled with insulating oil. The insulating oil does not leak.
The cleat 10 is made of FRP, is cheaper than conventional aluminum, and is easy to handle due to its light weight.
The trough A may be filled with concrete.
