Description
【考案の詳細な説明】 本考案は、架空送電線用接地ローラーに関する。[Detailed explanation of the idea] The present invention relates to a grounding roller for overhead power transmission lines.
架空送電線を架設するにあたって、架設中の送電線が既

の状態に応じて適切な誘導防止対策を行う必要がある。When installing overhead power lines, if the power line being installed approaches or crosses existing live wires, high voltage will be generated in the power line due to the effects of electrostatic induction and electromagnetic induction. Appropriate guidance prevention measures must be taken accordingly.
かかる防止対策の−っとして、従来より、延線車の近傍

に接地することが行なわれている。As a preventive measure against this, conventionally, grounding rollers having aluminum rollers have been placed near the track rolling cars, near the metal wheels of the steel towers, and near the winches, and the grounding rollers that come into contact with the aluminum rollers Grounding is done using a lead wire.
ところで、架空送電線の架設は、一般に、メツセンジャ
ーワイヤと送電線用の鋼心アルミ撚線とをてぎを介して

して行なわれている。By the way, the installation of overhead power transmission lines is generally done by connecting the metsenger wire and the steel-core aluminum stranded wire for the transmission line via a girder, and indexing it with a winch through a metal wheel installed on a steel tower. There is.

自重が掛ると共に、金車と接地ローラーのローラーに挾
まれてアルミ撚線が急激に通過する場合があるために、
アルミ撚線に外力が働き僅ではあるが凹み等の歪が発生
するという難点があった。However, especially in the vicinity of the metal wheel, the steel core aluminum stranded wire is subject to its own weight, and the aluminum stranded wire may pass rapidly while being caught between the metal wheel and the ground roller.
There was a problem in that external forces acted on the aluminum strands, causing slight distortions such as dents.
かかる歪は、振動疲労ひいては素線切れの原因となる虞

。Such distortion is undesirable because it may cause vibration fatigue and eventually breakage of the strands, as well as reduce the commercial value.

用接地ローラーを提供することを目的とする。The present invention has been made to solve these difficulties, and is an overhead power transmission line that includes a frame body that straddles the overhead power transmission line to be grounded, and a roller that is attached to the frame body and comes into contact with the overhead power transmission line. In the grounding roller, at least the contact surface of the roller with the overhead power transmission line is formed of rubber, and a grounding brush is provided that is resiliently sprung by a spring and comes into contact with the overhead power transmission line, and this grounding brush is electrically connected. An object of the present invention is to provide a grounding roller for an overhead power transmission line, characterized in that a connected flexible grounding lead wire is provided.
以下、図面に基づき本考案の一実施例を詳述する。Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.
第1図に示すように、本考案に係る架空送電線用ローラ
ーは、方形の枠体1の底部にウェスト2゜2′を固着し
て外観を構成している。As shown in FIG. 1, the appearance of the overhead power transmission line roller according to the present invention is constructed by fixing a waist 2° 2' to the bottom of a rectangular frame 1.
3′は、接地用リード線である。3' is a grounding lead wire.
第2図に示すように、枠体1の内部には、ローラー4.
4’が設けられている。As shown in FIG. 2, inside the frame 1, there are rollers 4.
4' is provided.
ローラー4,4′は、枠体1の側面に固定された軸5,
5′に軸支され、架空送電線3が通過する溝6(第3図
)が設けられている。The rollers 4, 4' have shafts 5,
5' is provided with a groove 6 (FIG. 3) through which the overhead power transmission line 3 passes.
なお、軸5,5′には、ローラー4,4′を軸5,5′
の中央に留置するリング7.7′・・・・・・が設けら
れている。Note that the rollers 4, 4' are attached to the shafts 5, 5'.
A ring 7.7' is provided to be placed in the center of the ring.
ローラー4,4′は全体をゴムで形成するか又は、溝6
にゴムを張設して構成されている。The rollers 4, 4' may be made entirely of rubber, or may be formed with grooves 6.
It is made up of rubber covered.
また、枠体1内には、ブラシ8・・・・・・が固定部材

* is configured to be bundled by a support member 10, resiliently pushed by a spring 11, and pressed against the overhead power transmission line 3.
そしてブラシ8・・・・・・の他端には、接地用ノード
線3′が接続されて枠1外に延在している。A grounding node line 3' is connected to the other end of the brush 8 and extends outside the frame 1.
而して、上記ローラー4,4′の溝面およびブラシ8・

れて、本考案の接地用ローラーを構成している。Thus, the groove surfaces of the rollers 4 and 4' and the brushes 8 and
... is disposed within the frame so that one end is in a straight line, and constitutes the grounding roller of the present invention.
なお、本考案の使用方法は、従来の接地ローラーと異る
ところはない。Note that the method of using the present invention is no different from that of conventional ground rollers.

因を解悄することができ効果甚大である。As explained above, according to the present invention, the roller of the grounding roller is made of rubber or rubber-covered, and the spring-loaded brush is brought into contact with the electric wire, so that the electric wire is suddenly pulled and installed. Even in such cases, the rubber acts as a cushioning material, and the brushes are pressed against the wires with a small enough contact pressure to ground them, so there is no risk of dents, etc., thus reducing vibration fatigue and, ultimately, vibration fatigue. It can eliminate the cause of line breakage and is highly effective.
