Description

本発明は、延線クランプ、延線クランプ連結部材、延線クランプ接続構造体及びフリクションスポット接合装置、並びに延線クランプ接続工法に関し、特に、送電線の建設（延線・電線の接続）及び運用保守管理を実施する際に用いられる延線クランプ及び延線クランプ接続構造体に関する。 The present invention relates to a wire drawing clamp, a wire drawing clamp connecting member, a wire drawing clamp connecting structure and a friction spot joining device, and a wire drawing clamp connecting method, in particular, construction (connection of wire drawing and electric wire) and operation of a transmission line. It relates to a wire drawing clamp and a wire drawing clamp connection structure used when carrying out maintenance management.

従来、送電線を建設するには、敷設される線路の下に様々な建設物や使用中の用地があるため、それらを避けて、電線を空中に位置しながら鉄塔間に敷設する必要がある。このため、鉄塔間への敷設の際、地上とのクリアランスを確保しながら電線に張力をかけるために、延線作業の仮接続時に、電線の端部に延線クランプが取り付けられる。 Conventionally, in order to construct a transmission line, there are various structures and land in use under the track to be laid, so it is necessary to avoid them and lay the electric wire between the towers while being located in the air. .. Therefore, in order to apply tension to the electric wire while ensuring a clearance with the ground when laying between the towers, a wire drawing clamp is attached to the end of the electric wire at the time of temporary connection of the wire drawing work.

従来の延線クランプとしては、例えば、電線の端部をくさびによって固定するくさび型延線クランプや、電線の端部のうち鋼線の部分を鋼線圧縮部に挿入して加締めると共に、アルミニウム線の部分をアルミニウム線圧縮部に挿入して加締める圧縮型延線クランプが知られている（特許文献１）。くさび型延線クランプや圧縮型延線クランプはいずれも、延線作業の本接続において碍子連に電線を引き留めた後は不要となり、電線の端部から取り外される。また、これらクランプのいずれも、通常、鉄塔間への施設の際に電線に張力をかけるのに十分な機械的特性を有するように設計され、クランプ内に電気を流すように設計されていない。 Conventional wire drawing clamps include, for example, a wedge-shaped wire drawing clamp that fixes the end of an electric wire with a wedge, and a steel wire part of the end of an electric wire that is inserted into a steel wire compression part and crimped, and aluminum. A compression type wire drawing clamp is known in which a wire portion is inserted into an aluminum wire compression portion and crimped (Patent Document 1). Both the wedge-shaped wire drawing clamp and the compression-type wire drawing clamp are no longer needed after the wire is fastened to the insulator in the main connection of the wire drawing work, and are removed from the end of the wire. Also, none of these clamps are typically designed to have sufficient mechanical properties to tension the wires during installation between towers and not to allow electricity to flow through the clamps.

そこで、延線クランプの機能を持ちつつ、碍子連に電線を引き留めた後に電線端部から取り外す必要が無く、加えてクランプ内に電気を流すことも可能にした金車通過型引留クランプ（圧縮型引留クランプ）がある。この金車通過型引留クランプを用いると、新たに敷設される電線（本線）の端部と引留クランプとの圧縮を地上で行うことができるため、鉄搭上での上記圧縮作業を省略することができる。また、例えば耐張鉄塔に用いられる金車通過型引留クランプには、ジャンパソケットが取り付けられる接続部が設けられており、金車通過型引留クランプを碍子連に引き留めて連結した後、所定長さのジャンパ線の端部にジャンパソケットを圧縮し、ジャンパソケットを金車通過型引留クランプの接続部に接合することで、電線（本線）とジャンパ線との電気的な接続が可能となっている（特許文献２）。 Therefore, while having the function of a wire drawing clamp, it is not necessary to remove the wire from the end of the wire after fastening the wire to the insulator, and in addition, it is possible to pass electricity through the clamp. There is a retention clamp). By using this metal wheel passing type retention clamp, it is possible to compress the end of the newly laid electric wire (main line) and the retention clamp on the ground, so the above compression work on the steel tower can be omitted. Can be done. Further, for example, the metal wheel passing type retaining clamp used for a tension steel tower is provided with a connection portion to which a jumper socket is attached, and after the metal wheel passing type retaining clamp is fastened and connected to the insulator chain, it has a predetermined length. By compressing the jumper socket at the end of the jumper wire and joining the jumper socket to the connection part of the insulator-passing type retention clamp, the electric wire (main line) and the jumper wire can be electrically connected. (Patent Document 2).

また、上記のような引留クランプとジャンパソケットとの接合方法において、フリクションスポット接合（以下、「ＦＳＪ」ともいう）が用いられることがある。ＦＳＪとは、一般に電車などの車両製作で用いられる接合方法の一つであり、機械的に回転する工具で金属同士を接合する技術である。このような接合方法としては、例えば、引留クランプとジャンパソケットとの接続部において、クランプ本体の側面とジャンパソケットの側面との間に金属体を配置し、クランプ本体と金属体、及びジャンパソケットと金属体とを、それぞれＦＳＪにより点接合することで、引留クランプとジャンパソケットとの電気的な接続を可能とする方法が提案されている（特許文献３）。 Further, in the method of joining the retaining clamp and the jumper socket as described above, friction spot joining (hereinafter, also referred to as “FSJ”) may be used. FSJ is one of the joining methods generally used in the manufacture of vehicles such as trains, and is a technique for joining metals with a mechanically rotating tool. As such a joining method, for example, at the connection portion between the retaining clamp and the jumper socket, a metal body is arranged between the side surface of the clamp body and the side surface of the jumper socket, and the clamp body and the metal body, and the jumper socket A method has been proposed that enables electrical connection between a retention clamp and a jumper socket by point-joining each metal body with an FSJ (Patent Document 3).

また、鉄塔の碍子連に引留クランプを介して引留められた電線同士をジャンパ線で接続する際には、ジャンパ装置が用いられる。ジャンパ装置としては、例えば、鉄塔両側の送電線本線を電気的に接続するジャンパ導体の全てを電線（撚線）で構成する方式、すなわちジャンパ導体がジャンパ線のみからなる撚線式ジャンパ装置や、ジャンパ線全体の中間部を水平吊架材により水平に吊架した吊架式ジャンパ装置、あるいは、ジャンパ線の中央部をジャンパパイプに置き換えたパイプ式ジャンパ装置がある（特許文献４）。 Further, a jumper device is used when connecting electric wires fastened to the insulator series of a steel tower via a retaining clamp with jumper wires. As a jumper device, for example, a method in which all the jumper conductors that electrically connect the main transmission lines on both sides of the tower are composed of electric wires (twisted wires), that is, a stranded wire type jumper device in which the jumper conductor consists of only jumper wires. There is a suspension type jumper device in which the middle part of the entire jumper wire is horizontally suspended by a horizontal suspension material, or a pipe type jumper device in which the central part of the jumper wire is replaced with a jumper pipe (Patent Document 4).

しかしながら、特許文献１の技術では、上述のように、碍子連に電線を引留めた後は延線クランプが不要となるため、これを取り除くことが必要であり、鉄塔上で延線クランプの除去作業が必要となる。また、除去作業の際に切断された電線は、隣接する電線（例えば、ジャンパ線）との電気的接続が必要となる。このとき、圧縮型引留クランプや圧縮型ジャンパスリーブ等を用いて、鉄塔上或いは空中で重さ５０ｋｇ程度の工具を用いて圧縮作業を行うため、当該作業が困難であると共に、重労働且つ長い作業時間を要する。また、当該作業時における作業者の安全性を確保しなければならず、作業時間や手間がより一層増大することとなる。 However, in the technique of Patent Document 1, as described above, since the wire drawing clamp becomes unnecessary after the electric wire is fastened to the insulator, it is necessary to remove it, and the wire drawing clamp is removed on the steel tower. Work is required. In addition, the electric wire cut during the removal operation needs to be electrically connected to an adjacent electric wire (for example, a jumper wire). At this time, since the compression work is performed using a compression type retaining clamp, a compression type jumper sleeve, or the like with a tool having a weight of about 50 kg on the steel tower or in the air, the work is difficult, and it is hard work and long working time. Needs. In addition, the safety of the worker at the time of the work must be ensured, and the work time and labor will be further increased.

また、一般に、金車通過型引留クランプは、碍子連の先端で電線を引留める構成であるため、電線が一延線区間の電線実長に合致する長さとなるように事前に精度の高い電線計尺を行う必要があり、その作業が煩雑である。また、特許文献２の技術では、圧縮型引留クランプとジャンパソケットとを座標変換金具を介してジャンパボルトで締結しているため、上記クランプとソケットとの界面の劣化により、接続部での電気抵抗の上昇や発熱の恐れが懸念されることから、定期的な保守管理が必要である。 In addition, since the metal wheel passing type retaining clamp is generally configured to hold the electric wire at the tip of the insulator, the electric wire is highly accurate in advance so that the electric wire has a length that matches the actual length of the electric wire in the extended wire section. It is necessary to measure the scale, and the work is complicated. Further, in the technique of Patent Document 2, since the compression type retaining clamp and the jumper socket are fastened with jumper bolts via the coordinate conversion metal fittings, the electrical resistance at the connection portion due to the deterioration of the interface between the clamp and the socket. Regular maintenance is required because there is a concern that the temperature will rise and heat will be generated.

また、特許文献３の技術では、ＦＳＪによって引留クランプとジャンパソケットとの電気的な接続が可能としているが、一般的なＦＳＪ装置はいわゆる据え置き型が多く、持ち運び型ではないため、鉄塔上或いは空中でＦＳＪを行うことは事実上困難である。よって、引留クランプとジャンパソケットとのＦＳＪを、鉄塔上或いは空中で容易に且つ安全に作業することが可能なＦＳＪ装置が求められている。 Further, in the technique of Patent Document 3, the retention clamp and the jumper socket can be electrically connected by FSJ. However, since many general FSJ devices are so-called stationary type and not portable type, they are on a steel tower or in the air. It is practically difficult to perform FSJ in. Therefore, there is a demand for an FSJ device capable of easily and safely working the FSJ between the retention clamp and the jumper socket on a steel tower or in the air.

更に、特許文献４の技術では、ジャンパ線と鉄塔との間、或いはジャンパ線同士で絶縁間隔を確保しなければならず、風の発生時においても上記絶縁間隔が確保されるように電線計尺を行う必要があり、ジャンパ装置の設計が煩雑である。 Further, in the technique of Patent Document 4, it is necessary to secure an insulation interval between the jumper wire and the steel tower, or between the jumper wires, and the electric wire scale so that the insulation interval is secured even when wind is generated. The design of the jumper device is complicated.

筒状部１１は、電線１２の先端部１２Ａのうちの外周部の金属線を圧縮可能な第１圧縮部１１１と、その内部の他の金属線を圧縮可能な第２圧縮部１１２とを有する。電線１２の構成は、特に制限はないが、例えば外周部にアルミニウム線が配置され、その内部に鋼線が配置された構成が挙げられる。この場合、第１圧縮部１１１は、電線１２の先端部のうちの外周部のアルミニウム線を圧縮可能に構成され、第２圧縮部１１２は、内部の鋼線を圧縮可能に構成される。 The tubular portion 11 has a first compression portion 111 capable of compressing a metal wire on the outer peripheral portion of the tip portion 12A of the electric wire 12, and a second compression portion 112 capable of compressing other metal wires inside the tubular portion 11. .. The configuration of the electric wire 12 is not particularly limited, and examples thereof include a configuration in which an aluminum wire is arranged on the outer peripheral portion and a steel wire is arranged inside the aluminum wire. In this case, the first compression portion 111 is configured to be able to compress the aluminum wire on the outer peripheral portion of the tip portion of the electric wire 12, and the second compression portion 112 is configured to be able to compress the steel wire inside.

筒状部１１は、例えば、その外周面の径方向断面において六角形状等の多角形状を有し、内周面の径方向断面において円形状を有している。第１筒状部１１の外周面の径方向断面及び内周面の径方向断面における形状は、特に制限はなく、上記形状以外の形状であってもよい。 The tubular portion 11 has, for example, a polygonal shape such as a hexagonal shape in the radial cross section of the outer peripheral surface thereof, and a circular shape in the radial cross section of the inner peripheral surface thereof. The shapes of the outer peripheral surface of the first tubular portion 11 in the radial cross section and the inner peripheral surface in the radial cross section are not particularly limited and may be shapes other than the above shapes.

係合部１３は、筒状部１１の一端部１１Ａに取り付けられた基部１３１と、基部１３１から筒状部１１の長手方向外方に向かって延出した延出部１３２とを有している。基部１３１は、例えば延出部１３２とは反対側に設けられた断面略六角形状の凸部を有しており、当該凸部が筒状部１１の他端部１１Ｂと圧縮接合されることで、係合部１３が筒状部１１に固定される。第１延出部１３２には貫通孔１３３が設けられており、例えば碍子連の端部に設けられた金具（不図示）が貫通孔１３３と係合する。 The engaging portion 13 has a base portion 131 attached to one end portion 11A of the tubular portion 11 and an extending portion 132 extending outward from the base portion 131 in the longitudinal direction of the tubular portion 11. ..

The first extending portion 132 is provided with a through hole 133, and for example, a metal fitting (not shown) provided at the end of the insulator chain engages with the through hole 133.

延線クランプ１は、金属で構成されており、例えばアルミニウム又はアルミニウム合金で構成されている。アルミニウムとしては、例えばＡ１０５０、Ａ１０７０などのいわゆる純アルミニウム（純度９９％以上）が挙げられる。筒状部１１と係合部１３は、異なる金属材料で構成されていてもよく、例えば筒状部１１がアルミニウム又はアルミニウム合金で構成され、係合部１３は鋼（Ｆｅ）で構成されている。 The wire drawing clamp 1 is made of metal, for example, aluminum or an aluminum alloy.

図２（ａ）〜図２（ｃ）に示すように、延線クランプ接続構造体２は、第１延線クランプ１−１と、第２延線クランプ１−２と、第１延線クランプ１−１と第２延線クランプ１−２とを連結する延線クランプ用連結板材３と、第１延線クランプ１−１と延線クランプ用連結板材３とがＦＳＪによって接合されている第１接合部４−１，４−１と、第２延線クランプ１−２と延線クランプ用連結板材３とがＦＳＪによって接合されている第２接合部４−２，４−２とを備える。 As shown in FIGS. 2 (a) to 2 (c), the wire drawing clamp connection structure 2 includes a first wire drawing clamp 1-1, a second wire drawing clamp 1-2, and a first wire drawing clamp.

図３は、図２（ｂ）の破線部分における第１接合部４−１及び第２接合部４−２の部分拡大断面図である。
第１接合部４−１は、第１延線クランプ１−１の側面１１ａ−１に設けられた第１接合面１４−１と、延線クランプ用連結板材３の側面３ａに設けられた第１被接合面３ａ−１との接合によって形成されている。また、第２接合部４−２は、第２延線クランプ１−２の側面１１ａ−２に設けられた第２接合面１４−２と、延線クランプ用連結板材３の側面３ａに設けられた第２被接合面３ａ−２との接合によって形成されている。 FIG. 3 is a partially enlarged cross-sectional view of the first joint portion 4-1 and the second joint portion 4-2 in the broken line portion of FIG. 2 (b).
The first joint portion 4-1 is provided on the first joint surface 14-1 provided on the side surface 11a-1 of the first wire drawing clamp 1-1 and the side surface 3a of the wire drawing clamp connecting plate member 3. 1 It is formed by joining with the surface to be joined 3a-1. Further, the second joint portion 4-2 is provided on the second joint surface 14-2 provided on the side surface 11a-2 of the second wire drawing clamp 1-2 and the side surface 3a of the wire drawing clamp connecting plate member 3. It is formed by joining with the second surface to be joined 3a-2.

第１接合部４−１には、ＦＳＪ時に使用される後述する回転軸部材の先端部形状に対応する凹部５−１が形成されている。凹部５−１は、段付き形状を有する円筒型の穴であり、第１延線クランプ１−１の幅方向内方に向かって設けられている。また、第２接合部４−２には、ＦＳＪ時に使用された後述する回転軸部材の先端部形状に対応する凹部５−２が形成されている。凹部５−２は、凹部５−１と同様、段付き形状を有する円筒型の穴であり、第２延線クランプ１−２の径方向内方に向かって設けられている。本実施形態では、凹部５−２の形状及び寸法は、凹部５−１の形状及び寸法と同じであるが、これに限らず、凹部５−１の形状及び寸法と異なっていてもよい。 The first joint portion 4-1 is formed with a recess 5-1 corresponding to the shape of the tip portion of the rotary shaft member used at the time of FSJ, which will be described later. The recess 5-1 is a cylindrical hole having a stepped shape, and is provided inward in the width direction of the first wire drawing clamp 1-1. Further, the second joint portion 4-2 is formed with a recess 5-2 corresponding to the shape of the tip portion of the rotary shaft member used at the time of FSJ, which will be described later. The recess 5-2 is a cylindrical hole having a stepped shape like the recess 5-1 and is provided inward in the radial direction of the second wire drawing clamp 1-2. In the present embodiment, the shape and dimensions of the recess 5-2 are the same as the shape and dimensions of the recess 5-1 but are not limited to this, and may be different from the shape and dimensions of the recess 5-1.

ＦＳＪによって第１接合部４−１を形成する際、延線クランプ用連結板材３の金属と第１延線クランプ１−１の金属との塑性流動が生じてこれらが混ざり合うことにより、延線クランプ用連結板材３の一部と第１延線クランプ１−１の一部とが金属的に一体化される。よって、第１接合部４−１では、第１延線クランプ１−１と延線クランプ用連結板材３との金属的な結合によってこれらの間に界面が無い状態となっている。また、ＦＳＪによって第２接合部４−２を形成する際にも、延線クランプ用連結板材３の金属と第２延線クランプ１−２の金属との塑性流動が生じ、延線クランプ用連結板材３の一部と第２延線クランプ１−２の一部とが金属的に一体化される。よって、第２接合部４−２でも、第２延線クランプ１−２と延線クランプ用連結板材３との金属的な結合によってこれらの間に界面が無い状態となっている。これにより、第１延線クランプ１−１と第２延線クランプ１−２とが、延線クランプ用連結板材３を介して電気的或いは機械的に接続される。 When the first joint portion 4-1 is formed by the FSJ, a plastic flow is generated between the metal of the wire drawing clamp connecting plate 3 and the metal of the first wire drawing clamp 1-1, and these are mixed to cause wire drawing. A part of the clamp connecting plate 3 and a part of the first wire drawing clamp 1-1 are metallically integrated. Therefore, in the first joint portion 4-1 there is no interface between the first wire drawing clamp 1-1 and the wire drawing clamp connecting plate member 3 due to the metallic bond. Further, when the second joint portion 4-2 is formed by the FSJ, the metal of the wire drawing clamp connecting plate 3 and the metal of the second wire drawing clamp 1-2 are plastically flowed, and the wire drawing clamp is connected. A part of the plate material 3 and a part of the second wire drawing clamp 1-2 are metallically integrated. Therefore, even in the second joint portion 4-2, there is no interface between the second wire drawing clamp 1-2 and the wire drawing clamp connecting plate member 3 due to the metallic bond. As a result, the first wire drawing clamp 1-1 and the second wire drawing clamp 1-2 are electrically or mechanically connected via the wire drawing clamp connecting plate member 3.

上記のように構成される延線クランプ用連結板材３を、第１延線クランプ１−１及び第２延線クランプ１−２の双方とＦＳＪにて接合することで、図３に示すような延線クランプ接続構造体２が形成される。 As shown in FIG. 3, the connecting plate member 3 for wire drawing clamps configured as described above is joined to both the first wire drawing clamp 1-1 and the second wire drawing clamp 1-2 by FSJ. The wire drawing clamp connection structure 2 is formed.

次に、延線クランプ１と延線クランプ用連結板材３とを接合する可動型フリクションスポット接合装置（以下、「可動型ＦＳＪ装置」ともいう）を説明する。
図５（ａ）は、本実施形態に係る可動型ＦＳＪ装置の構成を示す平面図であり、図５（ｂ）は、側面図である。 Next, a movable friction spot joining device (hereinafter, also referred to as “movable FSJ device”) for joining the wire drawing clamp 1 and the wire drawing clamp connecting plate material 3 will be described.
5 (a) is a plan view showing the configuration of the movable FSJ device according to the present embodiment, and FIG. 5 (b) is a side view.

図５（ａ）〜図５（ｂ）に示すように、可動型ＦＳＪ装置４は、回転可能に設けられた回転軸部材４１と、回転軸部材４１の軸方向に対して延線クランプ１の長手方向が垂直となる状態で当該延線クランプ１を支持可能な支持部４２と、支持部４２と回転軸部材４１とを相対的に移動して、支持部４２に支持された延線クランプ１に回転軸部材４１を押圧可能な移動機構４３とを備える。可動型ＦＳＪ装置４は、例えば、作業者が持ち運ぶことができるウェアラブルＦＳＪ装置であり、また、塔上或いは空中で作業可能なように、小型且つ軽量な構成となっている。 As shown in FIGS. 5A to 5B, in the movable FSJ device 4, the rotary shaft member 41 rotatably provided and the wire drawing clamp 1 with respect to the axial direction of the rotary shaft member 41 The wire drawing clamp 1 supported by the support portion 42 by relatively moving the support portion 42 capable of supporting the wire drawing clamp 1 in a state where the longitudinal direction is vertical, and the support portion 42 and the rotary shaft member 41. Is provided with a moving mechanism 43 capable of pressing the rotary shaft member 41. The movable FSJ device 4 is, for example, a wearable FSJ device that can be carried by an operator, and has a compact and lightweight configuration so that it can work on a tower or in the air.

回転軸部材４１は、円柱状の回転軸本体４１ａと、回転軸本体４１ａの端面に設けられた突起４１ｂとを有している（図５（ａ））。回転軸部材４１には、遊星ギア４４を介してモータ４５が連結されており、モータ４５の動力が回転軸部材４１に伝達されることで、回転軸部材４１が回転する。回転軸部材４１は、例えば移動機構４３によって延線クランプ用連結板材３に押圧された状態で回転することが可能であり、例えば押圧状態において所定回転数、例えば１５００ｒｐｍで回転する。 The rotary shaft member 41 has a columnar rotary shaft main body 41a and protrusions 41b provided on the end faces of the rotary shaft main body 41a (FIG. 5A). A motor 45 is connected to the rotary shaft member 41 via a planetary gear 44, and the power of the motor 45 is transmitted to the rotary shaft member 41 to rotate the rotary shaft member 41. The rotary shaft member 41 can be rotated in a state of being pressed by, for example, the wire drawing clamp connecting plate member 3 by the moving mechanism 43, and is rotated at a predetermined rotation speed, for example, 1500 rpm in the pressed state, for example.

モータ４５は、小型且つ軽量であって出力３ｋＷ以上であるのが好ましく、例えばブラシ付きモータである。これにより、回転軸部材４１が延線クランプ用連結板材３に押圧されながら回転しているときに、金属による摺動抵抗や粘性抵抗が生じたときにも、ＦＳＪを行うのに十分な動力で回転軸部材４１を回転させることができる。 The motor 45 is preferably small and lightweight and has an output of 3 kW or more, and is, for example, a brushed motor. As a result, even when the rotating shaft member 41 is rotating while being pressed by the wire drawing clamp connecting plate member 3 and sliding resistance or viscous resistance due to metal occurs, the power is sufficient to perform FSJ. The rotary shaft member 41 can be rotated.

支持部４２は、断面略Ｕ字型の溝部４２ａを有しており、溝部４２ａに延線クランプ１の少なくとも一部が収容されることで、延線クランプ１が支持される（図５（ｂ））。本実施形態では、支持部４２は溝部４２ａに底壁４２ｂを有しており、底壁４２ｂは、延線クランプ１の側面１１ｂと当接可能に形成されている。延線クランプ１の側面１１ｂは、延線クランプ用連結板材３と当接する側面１１ａと対向して配置されている。 The support portion 42 has a groove portion 42a having a substantially U-shaped cross section, and the wire drawing clamp 1 is supported by accommodating at least a part of the wire drawing clamp 1 in the groove portion 42a (FIG. 5 (b). )). In the present embodiment, the support portion 42 has a bottom wall 42b in the groove portion 42a, and the bottom wall 42b is formed so as to be in contact with the side surface 11b of the wire drawing clamp 1. The side surface 11b of the wire drawing clamp 1 is arranged so as to face the side surface 11a that comes into contact with the wire drawing clamp connecting plate member 3.

移動機構４３は、回転軸部材４１の軸方向に関して支持部４２を移動することで、当該回転軸部材４１に対して延線クランプ１を位置決めする。この移動機構４３は、支持部４２に支持された延線クランプ１と回転軸部材４１との間に延線クランプ用連結板材３を介在させた状態で、支持部４２を回転軸部材４１に近接するように移動して（図５（ａ），（ｂ）中の矢印方向）、延線クランプ用連結板材３を回転軸部材４１に押圧することが可能に構成される。回転軸部材４１の出力は、例えば５ｋＮである。また、移動機構４３は、支持部４２を回転軸部材４１から離間するように移動することが可能に構成される。移動機構４３は、例えば伸び方向及び縮み方向の双方に移動可能なシリンダであり、例えば油圧シリンダである。この場合、シリンダのピストンのストロークが最大となったときに、回転軸部材４１の突起４１ｂの一部が、支持部４２に支持された延線クランプ１の筒状体１１に食い込むように、支持部４２を位置決めするのが好ましい（図５（ａ））。 The moving mechanism 43 positions the wire drawing clamp 1 with respect to the rotating shaft member 41 by moving the support portion 42 with respect to the axial direction of the rotating shaft member 41. In this moving mechanism 43, the support portion 42 is brought close to the rotary shaft member 41 in a state where the wire drawing clamp connecting plate member 3 is interposed between the wire drawing clamp 1 supported by the support portion 42 and the rotary shaft member 41. (The direction of the arrow in FIGS. 5A and 5B), the wire drawing clamp connecting plate member 3 can be pressed against the rotary shaft member 41. The output of the rotating shaft member 41 is, for example, 5 kN. Further, the moving mechanism 43 is configured to be able to move the support portion 42 so as to be separated from the rotating shaft member 41. The moving mechanism 43 is, for example, a cylinder that can move in both the extending direction and the contracting direction, for example, a hydraulic cylinder. In this case, when the stroke of the piston of the cylinder is maximized, a part of the protrusion 41b of the rotating shaft member 41 is supported so as to bite into the tubular body 11 of the wire drawing clamp 1 supported by the support portion 42. It is preferable to position the portion 42 (FIG. 5A).

次に、延線クランプ１−１，１−２と延線クランプ用連結板材３とを接続する延線クランプ接続工法を説明する。本実施形態に係る延線クランプ接続工法では、例えば、図５に示す可動型ＦＳＪ装置４が用いられる。 Next, a wire drawing clamp connecting method for connecting the wire drawing clamps 1-1 and 1-2 and the wire drawing clamp connecting plate material 3 will be described. In the wire drawing clamp connection method according to the present embodiment, for example, the movable FSJ device 4 shown in FIG. 5 is used.

図６（ａ）〜図６（ｅ）は、本実施形態に係る延線クランプ接続工法を説明する図である。
図６（ａ）に示すように、先ず、第１延線クランプ１−１の第１筒状部１１−１に第１電線１２−１を挿入した状態で当該第１筒状部１１−１を圧縮して、第１延線クランプ１−１と第１電線１２−１とを接続する（第１電線圧縮工程）。同様に、第２延線クランプ１−２の第２筒状部１１−２に第２電線１２−２を挿入した状態で当該第２筒状部１１−２を圧縮して、第２延線クランプと前記第２電線とを接続する（第２電線圧縮工程）。 6 (a) to 6 (e) are views for explaining the wire drawing clamp connection method according to the present embodiment.
As shown in FIG. 6A, first, the first tubular portion 11-1 is inserted into the first tubular portion 11-1 of the first wire drawing clamp 1-1 with the first electric wire 12-1 inserted. Is compressed, and the first wire drawing clamp 1-1 and the first electric wire 12-1 are connected (first electric wire compression step). Similarly, with the second electric wire 12-2 inserted in the second tubular portion 11-2 of the second wire drawing clamp 1-2, the second tubular portion 11-2 is compressed to form the second wire. The clamp and the second electric wire are connected (second electric wire compression step).

第１延線クランプ１−１及び第２延線クランプ１−２はいずれも金車通過型であり、第１延線クランプ１−１と第１電線１２−１とを接続する工程、及び第２延線クランプ１−２と第２電線１２−２とを接続する工程のいずれも、地上で行うことができる。 Both the first wire drawing clamp 1-1 and the second wire drawing clamp 1-2 are of the metal wheel passing type, and the process of connecting the first wire drawing clamp 1-1 and the first electric wire 12-1 and the first. 2 Any of the steps of connecting the wire drawing clamp 1-2 and the second electric wire 12-2 can be performed on the ground.

次に、第１延線クランプ１−１と延線クランプ用連結板材３とをＦＳＪにて接合する（第１接合工程）（図６（ｂ））。第１延線クランプ１−１と延線クランプ用連結板材３とを接合する工程は、例えば可動型ＦＳＪ装置４を用いて、塔上或いは空中で行うことができる。
具体的には、先ず、可動型ＦＳＪ装置４の支持部４２で第１延線クランプ１−１を支持し、可動型ＦＳＪ装置４の支持部４２に支持された第１延線クランプ１−１と回転軸部材４１との間に延線クランプ用連結板材３を介在させた状態で、支持部４２を回転軸部材４１に近接するように移動して、回転軸部材４１を延線クランプ用連結板材３に押圧させる。
第１延線クランプ１−１と延線クランプ用連結板材３との接合時には、第１延線クランプ１−１に対して延線クランプ用連結板材３を固定する必要があるため、回転軸部材４１を延線クランプ用連結板材３に押圧することで、第１延線クランプ１−１に対して延線クランプ用連結板材３を固定する。
またこのとき、延線クランプ用連結板材３の板材本体３１の長手方向一端部３１Ａ側に設けられた第１の穴３２−１に回転軸部材４１を挿入する。これにより、接合位置の位置決めを容易とし、特に塔上或いは空中でＦＳＪを行う場合に、溶接などの他の接合方法と比較して接合位置の位置決めが極めて容易となり、作業性が向上する。
そして、回転軸部材４１を延線クランプ用連結板材３に押圧させた状態で、回転軸部材４１を所定回転数で数秒間回転させて、第１延線クランプ１−１と延線クランプ用連結板材３とをＦＳＪにて接合する。ＦＳＪによって形成された部分は金属的に一体化しているため、その後に経年劣化が生じ難く、電気的或いは機械的な接続信頼性が高い。また、一箇所の接合が数秒で行われるので、従来の接続作業と比較して、容易に且つ短時間で接続作業が完了する。
上記接合を２箇所で行うことにより、第１延線クランプ１−１と延線クランプ用連結板材３との境界部に第１接合部４−１，４−１が形成される（図６（ｃ））。 Next, the first wire drawing clamp 1-1 and the wire drawing clamp connecting plate material 3 are joined by FSJ (first joining step) (FIG. 6 (b)). The step of joining the first wire drawing clamp 1-1 and the wire drawing clamp connecting plate material 3 can be performed on a tower or in the air by using, for example, a movable FSJ device 4.
Specifically, first, the first wire drawing clamp 1-1 is supported by the support portion 42 of the movable FSJ device 4, and the first wire drawing clamp 1-1 is supported by the support portion 42 of the movable FSJ device 4. With the wire drawing clamp connecting plate 3 interposed between the rotating shaft member 41 and the rotating shaft member 41, the support portion 42 is moved so as to be close to the rotating shaft member 41, and the rotating shaft member 41 is connected for the wire drawing clamp. The plate material 3 is pressed.
When joining the first wire drawing clamp 1-1 and the wire drawing clamp connecting plate material 3, it is necessary to fix the wire drawing clamp connecting plate material 3 to the first wire drawing clamp 1-1, so that the rotating shaft member By pressing 41 against the wire drawing clamp connecting plate material 3, the wire drawing clamp connecting plate material 3 is fixed to the first wire drawing clamp 1-1.
At this time, the rotary shaft member 41 is inserted into the first hole 32-1 provided on the one end portion 31A side in the longitudinal direction of the plate material main body 31 of the wire drawing clamp connecting plate material 3. This facilitates the positioning of the joining position, and especially when the FSJ is performed on the tower or in the air, the positioning of the joining position becomes extremely easy as compared with other joining methods such as welding, and the workability is improved.
Then, in a state where the rotating shaft member 41 is pressed against the wire drawing clamp connecting plate member 3, the rotating shaft member 41 is rotated at a predetermined rotation speed for several seconds to connect the first wire drawing clamp 1-1 and the wire drawing clamp. The plate material 3 is joined by FSJ. Since the portion formed by the FSJ is metallically integrated, it is unlikely to deteriorate over time after that, and the electrical or mechanical connection reliability is high. Further, since the joining at one place is performed in a few seconds, the connecting work is completed easily and in a short time as compared with the conventional connecting work.

The step of joining the second wire drawing clamp 1-2 and the wire drawing clamp connecting plate material 3 can also be performed on the tower or in the air by using the movable FSJ device 4 in the same manner as described above.

第２延線クランプ１−２と延線クランプ用連結板材３との接合時にも、可動型ＦＳＪ装置４の支持部４２で第２延線クランプ１−２を支持し、可動型ＦＳＪ装置４の支持部４２に支持された第２延線クランプ１−２と回転軸部材４１との間に延線クランプ用連結板材３を介在させた状態で、支持部４２を回転軸部材４１に近接するように移動して、回転軸部材４１を延線クランプ用連結板材３に押圧させる。これにより、第２延線クランプ１−２に対して延線クランプ用連結板材３が固定される。
また、延線クランプ用連結板材３の板材本体３１の長手方向他端部３１Ｂ側に設けられた第２の穴３２−２に回転軸部材４１を挿入し、且つ回転軸部材４１を延線クランプ用連結板材３に押圧させた状態で、回転軸部材４１を所定回転数で数秒間回転させて、第２延線クランプ１−２と延線クランプ用連結板材３とをＦＳＪにて接合する。
上記接合を２箇所で行うことにより、第２延線クランプ１−２と延線クランプ用連結板材３との境界部に第２接合部４−２，４−２が形成される（図６（ｅ））。これにより、第１延線クランプ１−１と第２延線クランプ１−２が延線クランプ用連結板材３を介して電気的、機械的に接続される。 Even when the second wire drawing clamp 1-2 and the wire drawing clamp connecting plate material 3 are joined, the support portion 42 of the movable FSJ device 4 supports the second wire drawing clamp 1-2, and the movable FSJ device 4 The support portion 42 is brought close to the rotary shaft member 41 with the wire drawing clamp connecting plate member 3 interposed between the second wire drawing clamp 1-2 supported by the support portion 42 and the rotary shaft member 41. The rotary shaft member 41 is pressed against the wire drawing clamp connecting plate member 3. As a result, the wire drawing clamp connecting plate material 3 is fixed to the second wire drawing clamp 1-2.
Further, the rotating shaft member 41 is inserted into the second hole 32-2 provided on the other end 31B side in the longitudinal direction of the plate material main body 31 of the connecting plate material 3 for wire drawing clamp, and the rotating shaft member 41 is drawn and clamped. The rotating shaft member 41 is rotated at a predetermined rotation speed for several seconds while being pressed against the connecting plate material 3 for wire drawing, and the second wire drawing clamp 1-2 and the connecting plate material 3 for wire drawing clamp are joined by FSJ.
By performing the above joining at two points, the second joining portion 4-2, 4-2 is formed at the boundary portion between the second wire drawing clamp 1-2 and the wire drawing clamp connecting plate material 3 (FIG. 6 (FIG. 6). e)). As a result, the first wire drawing clamp 1-1 and the second wire drawing clamp 1-2 are electrically and mechanically connected via the wire drawing clamp connecting plate member 3.

Fix it to the steel tower 53 with (shown) or the like. That is, since the main line 54 and the main line 55 are supported by the steel tower 53, the jumper wires 51A, 51B, 51C and the jumper wires 52A, 52B, 52C connected to the three extension clamp connection structures 2A, 2B, 2C Almost no tensile load is applied to any of them. Therefore, stress is unlikely to occur in the first joint portion and the second joint portion of each wire drawing clamp connection structure, and the electrical connection at the first joint portion and the second joint portion can be maintained for a long period of time. ..
