Description

本発明はトロリ線ねじれ直し工具に関するものである。   The present invention relates to a trolley wire retwisting tool.

トロリ線は、パンタグラフを通じて車両に給電を行う接触電線であり、その外周の上部には電線の長手方向に沿って二本の凹溝が形成されている。そして、吊架線の各所から吊るされた複数のハンガーが、その下端部に設けられた一対の爪によりトロリ線の二本の凹溝を挟持してトロリ線を吊架支持している。トロリ線は、このように、上部に設けられた二本の凹溝によって吊架支持されるので、外周のほぼ下半分をパンタグラフとの摺接領域として使用することができる。   The trolley wire is a contact wire that feeds power to the vehicle through a pantograph, and two concave grooves are formed in the upper part of the outer periphery along the longitudinal direction of the wire. A plurality of hangers suspended from various portions of the suspension line support the suspension of the trolley wire by sandwiching two concave grooves of the trolley wire by a pair of claws provided at the lower end portion thereof. Thus, the trolley wire is suspended and supported by the two concave grooves provided in the upper portion, so that the substantially lower half of the outer periphery can be used as a sliding contact region with the pantograph.

ところで、トロリ線Ｔ同士を連結する場合には、図９〜図１１に示すように、トロリ線Ｔの接続端部を隣り合うように並べた状態でそれぞれのトロリ線Ｔの凹溝Ｍをクランプして保持する連結具であるダブルイヤー２００が使用される。
このダブルイヤー２００は、側面視略台形のブロック状であり、その底面部には接続するトロリ線を並べて保持するための二本の挟持溝２０１が形成されており、各挟持溝２０１の内側にはトロリ線Ｔの凹溝Ｍに嵌合する一対の爪２０２が向き合うように形成されている。
そして、このダブルイヤー２００は、二本の挟持溝２０１を境にして三つの部材２０４〜２０６に分離可能である。二本のトロリ線Ｔを連結する際には、各部材を分離させた状態で各爪をトロリ線Ｔの凹溝Ｍに嵌合させながら挟持溝２０１の内側に挟み、三つの部材をボルト２０３によって締結して一体化させることにより各トロリ線Ｔをクランプし連結する。 By the way, when connecting the trolley wires T, as shown in FIGS. 9 to 11, the concave grooves M of the trolley wires T are clamped in a state where the connecting ends of the trolley wires T are arranged adjacent to each other. The double ear 200 which is a connecting tool to be held is used.
The double ear 200 has a substantially trapezoidal block shape when viewed from the side, and has two holding grooves 201 for holding and holding the trolley wires to be connected to each other on the bottom surface. Is formed so that a pair of claws 202 fitted in the groove M of the trolley wire T face each other.
And this double ear 200 is separable into the three members 204-206 on the boundary of the two clamping grooves 201. FIG. When connecting the two trolley wires T, the claws are held inside the holding groove 201 while being fitted in the concave grooves M of the trolley wire T in a state where the members are separated, and the three members are bolts 203. Each trolley wire T is clamped and connected by fastening and integrating with each other.

一方、トロリ線Ｔはパンタグラフとの接触圧を確保する必要が有るためある程度の剛性を有しており、長いものはねじれの癖がついている場合が多い。このため、上記ダブルイヤー２００によるトロリ線Ｔ同士の連結の際には、図１２に示すトロリキー２１０という専用工具を使用して二本のトロリ線Ｔの向きを揃える作業が必要となる。
トロリキー２１０は、棒状であって、その先端部が円弧状に湾曲して内側に爪２１１が形成されている。そして、この爪２１１をトロリ線Ｔの一方の凹溝Ｍに嵌合させながら湾曲部の内側にトロリ線Ｔを抱持し、トロリ線Ｔを中心にしてトロリキー２１０を回動させることで、テコの原理によってトロリ線Ｔのねじれを解消することができる。 On the other hand, the trolley wire T has a certain degree of rigidity because it needs to ensure a contact pressure with the pantograph, and a long wire often has a twisted wrinkle. For this reason, when the trolley wires T are connected to each other by the double ear 200, an operation of aligning the directions of the two trolley wires T using a dedicated tool called the trolley key 210 shown in FIG.
The trolley key 210 has a bar shape, and a tip portion thereof is curved in an arc shape, and a claw 211 is formed inside. Then, the claw 211 is fitted into one groove M of the trolley wire T, the trolley wire T is held inside the curved portion, and the trolley key 210 is rotated around the trolley wire T, thereby The twist of the trolley wire T can be eliminated by the above principle.

つまり、ダブルイヤー２００によりトロリ線Ｔを連結する作業を行う場合には、トロリキー２１０によりトロリ線Ｔのねじれを直す作業者と、二本のトロリ線Ｔにダブルイヤー２００を取り付ける作業者の二名が必要だった。
また、このダブルイヤー２００の取り付けは熟練を要する作業だが、高所で行うことが多く、作業をさらに困難なものとしていた。
また、給電を受ける車両の走行を中断させている場合等には、トロリ線Ｔの連結作業は迅速に行う必要があるので、接続作業をより簡単に迅速に行うことが求められていた。 That is, when the operation of connecting the trolley wire T with the double ear 200 is performed, there are two operators, one who repairs the twist of the trolley wire T with the trolley key 210 and the other who attaches the double ear 200 to the two trolley wires T. It was necessary.
The installation of the double ear 200 is an operation that requires skill, but is often performed at a high place, making the operation more difficult.
Further, when the traveling of the vehicle that receives power supply is interrupted, the connecting operation of the trolley wire T needs to be performed quickly, and therefore, it has been required to perform the connecting operation more easily and quickly.

そこで、ダブルイヤーの２０３のネジ穴に棒状の把手をねじ込み、一方のトロリ線Ｔのみを一方の挟持溝２０１に挟持して、把手により一方のトロリ線Ｔを回動させて他方のトロリ線Ｔと凹溝Ｍの向きを揃え、他方のトロリ線Ｔもダブルイヤー２００に挟持する方法が提案されている（例えば、特許文献１参照）。   Therefore, a rod-like handle is screwed into the screw hole of the double ear 203, only one trolley wire T is clamped in one clamping groove 201, and one trolley wire T is rotated by the handle so that the other trolley wire T is rotated. A method has been proposed in which the direction of the groove M is aligned and the other trolley wire T is sandwiched between the double ears 200 (see, for example, Patent Document 1).

特開２０００−２８０７９５号公報JP 2000-280795 A

しかしながら、上記従来のトロリ線Ｔの連結作業では、一方のトロリ線Ｔはダブルイヤー２００により拘束されているが、他方のトロリ線Ｔは拘束されていない状態になるので、他方のトロリ線Ｔを拘束する作業者とダブルイヤー２００のボルト２０３を締結する作業者とが必要であり、作業者人数の低減を図ることはできなかった。
また、把手により一方のトロリ線の向きを調整した状態を維持しながら他方のトロリ線をダブルイヤー２００に挟持しボルト２０３を締結しなければならず、未だ作業の困難性は高かった。 However, in the connecting operation of the conventional trolley wire T, one trolley wire T is restrained by the double ear 200, but the other trolley wire T is not restrained. A worker who restrains and a worker who fastens the bolt 203 of the double ear 200 are necessary, and the number of workers cannot be reduced.
Further, while maintaining the state in which the direction of one of the trolley wires is adjusted by the handle, the other trolley wire must be sandwiched between the double ears 200 and the bolts 203 must be fastened, and the work is still difficult.

本発明は、トロリ線の連結作業の容易化をその目的とする。   An object of the present invention is to facilitate the operation of connecting trolley wires.

本発明は、二本のトロリ線を個別に挿通させる二つの挿通部を備える工具本体を有し、それぞれの前記挿通部の内側に、前記二本のトロリ線の凹溝の位置が揃うように前記凹溝に嵌まる突起部が設けられ、前記工具本体を複数の部材から構成して、前記二つの挿通部内の前記トロリ線の拘束状態と解放状態の切り替えを可能とし、少なくとも一方の前記挿通部内の前記突起部は、押し込み可能であって弾性体により突出方向に押圧されていることを特徴とする。   The present invention has a tool body provided with two insertion parts for individually inserting two trolley wires, and the positions of the concave grooves of the two trolley lines are aligned inside each of the insertion parts. Protrusions that fit into the concave grooves are provided, the tool body is composed of a plurality of members, and the trolley wire in the two insertion parts can be switched between a restrained state and a released state, and at least one of the insertions The protrusion in the part is pushable and is pressed in the protruding direction by an elastic body.

上記構成によれば、工具本体の二つの挿通部のそれぞれにトロリ線を挿通状態としたときに、トロリ線の凹溝に突起部を嵌合させることができる。また、少なくとも一方の突起部は押し込み可能なので、凹溝と突起部がずれた状態であっても、トロリ線を挿通部に拘束された状態で回動させることにより凹溝に突起部を嵌合させることができる。
このようにして、二本のトロリ線を、凹溝の位置を揃えた状態で拘束することができるので、ダブルイヤーの取り付け時に、トロリ線の向きを揃えた状態で維持する作業やトロリ線を取り付けに適した位置に拘束する作業を並行して行う必要性が解消される。 According to the said structure, when a trolley wire is made into the insertion state of each of the two insertion parts of a tool main body, a projection part can be fitted in the concave groove of a trolley line. In addition, since at least one of the protrusions can be pushed in, even if the groove and the protrusion are displaced, the protrusion is fitted into the groove by rotating the trolley wire while being restrained by the insertion part. Can be made.
In this way, the two trolley wires can be constrained in a state in which the positions of the grooves are aligned. The necessity of performing the work of restraining at a position suitable for attachment in parallel is eliminated.

また、前記工具本体を第一部材と第二部材と第三部材とから構成し、前記第一部材における前記第二部材との対向面に凹溝が設けられ、前記第三部材における前記第二部材との対向面に凹溝が設けられ、前記第二部材は前記第一部材の凹溝と前記第三部材の凹溝との間に仕切り壁部が設けられ、前記第一部材の凹溝と前記第二部材の仕切り壁部との間と前記第三部材の凹溝と前記第二部材の仕切り壁部との間とに前記二つの挿通部がそれぞれ形成されるようにする。
上記構成によれば、第一部材と第二部材と第三部材の相互間の対向面を接離させることにより、二つの挿通部内のトロリ線の拘束状態と解放状態の切り替えを容易に行うことが可能となる。 Further, the tool body is composed of a first member, a second member, and a third member, and a concave groove is provided on a surface of the first member facing the second member, and the second member in the third member is provided. A groove is provided on a surface facing the member, and the second member is provided with a partition wall portion between the groove of the first member and the groove of the third member, and the groove of the first member The two insertion portions are formed between the first member and the partition wall portion of the second member, and between the concave groove of the third member and the partition wall portion of the second member.
According to the above configuration, by switching the facing surfaces between the first member, the second member, and the third member, it is possible to easily switch between the restrained state and the released state of the trolley wires in the two insertion portions. Is possible.

本発明は、二本のトロリ線にダブルイヤーを取り付けて連結する際に、ダブルイヤーの取り付け時に、トロリ線の向きを揃えた状態で維持する作業やトロリ線を取り付けに適した位置に拘束する作業を並行して行う必要性が解消されるので、単独の作業者によるダブルイヤーの取り付け作業が可能となり、また、作業の容易化により作業時間の短縮化を図ることが可能となる。   In the present invention, when a double ear is attached and connected to two trolley wires, when the double ear is attached, the operation of maintaining the direction of the trolley wire in an aligned state and the trolley wire are restrained at a position suitable for attachment. Since the necessity of performing the work in parallel is eliminated, a single ear can be attached by a single worker, and the work time can be shortened by facilitating the work.

Further, in the restrained state of the insertion portion 22, the upper surface of the distal end portion of the extending portion 53 comes into contact with the lower end surface of the partition wall portion 42 of the second member 40.

上述のように、挿通部２２は、第三部材５０の周面部５２及び延出部５３と第二部材４０の仕切り壁部４２及び周面部４４とにより構成されている。従って、挿通部２２によるトロリ線Ｔの拘束状態から、第二部材４０に対して第三部材５０を回動させることにより、トロリ線Ｔの周囲全体を囲繞した状態を分断して解放状態となり、トロリ線Ｔを挿通部２２の外部に取り出すことができる。   As described above, the insertion portion 22 includes the peripheral surface portion 52 and the extending portion 53 of the third member 50, and the partition wall portion 42 and the peripheral surface portion 44 of the second member 40. Therefore, by rotating the third member 50 with respect to the second member 40 from the restrained state of the trolley wire T by the insertion portion 22, the state surrounding the entire periphery of the trolley wire T is divided into a released state, The trolley wire T can be taken out of the insertion portion 22.

また、第三部材５０の右側面から周面部５２の内周面にかけて、後述するラッチ機構６０を格納する格納孔５４が左右方向に沿って貫通形成されている。この格納孔５４は、第三部材５０の右側面の大径部５４１と周面部５２の内周面側の小径部５４２とから構成されている。そして、第三部材５０の右側面には、格納孔５４を塞ぐカバー５５がネジ止めにより取り付けられている。   Further, a storage hole 54 for storing a latch mechanism 60 described later is formed through the right and left sides of the third member 50 from the right side surface to the inner peripheral surface of the peripheral surface portion 52 along the left-right direction.

A chamfer 562 is provided at the lower right corner of the connection block 56 so that the stopper 72 can smoothly move to the press contact position by the rotation of the lever 71.

［ラッチ機構］
ラッチ機構６０は、第一部材３０の格納孔３４と第三部材５０の格納孔５４とにそれぞれ配置されているが、これらは同一の構成なので、主に、第一部材３０側のラッチ機構６０のみについて説明する。
ラッチ機構６０は、格納孔３４の内部において、周面部３２側に先端部を向けて格納された突起部としての突起部材６１と、突起部材６１を周面部３２側に向かって押圧する弾性体としてのコイルバネ６２とを備えている。 [Latch mechanism]
The latch mechanism 60 is disposed in each of the storage hole 34 of the first member 30 and the storage hole 54 of the third member 50. Since these are the same configuration, the latch mechanism 60 on the first member 30 side is mainly used. Only that will be described.
The latch mechanism 60 is a projecting member 61 as a projecting part that is stored with the tip end directed toward the peripheral surface part 32 inside the storage hole 34, and an elastic body that presses the projecting member 61 toward the peripheral surface part 32. The coil spring 62 is provided.

突起部材６１は、先端部が楔状にやや尖っており、後端部側は拡径部が設けられている。突起部材６１の先端部は周面部３２の内周面から突出して、トロリ線Ｔの凹溝Ｍに嵌合して当該トロリ線Ｔ回りの回転方向についてトロリ線Ｔを適正な向きに保持することができる。
突起部材６１の後端部の拡径部は、格納孔３４の大径部３４１と小径部３４２との境界の段差に当接して突起部材６１の過剰な飛び出しや脱落を防止している。
なお、格納孔３４は、当該格納孔３４から周面部３２内に突出する突起部材６１の先端部が挿通部２１内のトロリ線Ｔの所定の一方の凹溝Ｍに嵌合したときに、二つの凹溝Ｍが共にトロリ線Ｔにおける上部となるように、配置が決められている。 The protruding member 61 has a tip portion slightly sharpened like a wedge, and a diameter-expanded portion is provided on the rear end side. The front end portion of the protruding member 61 protrudes from the inner peripheral surface of the peripheral surface portion 32, fits into the groove M of the trolley wire T, and holds the trolley wire T in an appropriate direction with respect to the rotation direction around the trolley wire T. Can do.
The enlarged diameter portion at the rear end of the protruding member 61 is in contact with a step at the boundary between the large diameter portion 341 and the small diameter portion 342 of the storage hole 34 to prevent the protruding member 61 from excessively protruding or dropping off.
Note that the storage hole 34 is formed when the tip end portion of the protruding member 61 protruding into the peripheral surface portion 32 from the storage hole 34 is fitted into one predetermined groove M of the trolley wire T in the insertion portion 21. The arrangement is determined so that the two concave grooves M are at the upper part of the trolley line T.

コイルバネ６２は、突起部材６１を後方から押圧し、突起部材６１が拡径部により規制される位置まで突出した状態を維持する。また、突起部材６１は、その先端部を押圧することでコイルバネ６２に抗して退避させることができる。
例えば、挿通部２１にトロリ線Ｔを格納した場合に、その凹溝Ｍが突起部材６１の位置から離れている場合には、突起部材６１はコイルバネ６２に抗して退避位置に押し戻された状態を維持し、トロリ線Ｔの回転操作が行われて凹溝Ｍの位置と突起部材６１の位置とが合致したときに突起部材６１は突出して、その先端部を凹溝Ｍに嵌合させることができる。 The coil spring 62 presses the protruding member 61 from the rear, and maintains the state where the protruding member 61 protrudes to a position regulated by the enlarged diameter portion. Further, the protruding member 61 can be retracted against the coil spring 62 by pressing its tip.
For example, when the trolley wire T is stored in the insertion portion 21 and the concave groove M is away from the position of the protruding member 61, the protruding member 61 is pushed back to the retracted position against the coil spring 62. The protrusion member 61 protrudes when the trolley wire T is rotated and the position of the groove M matches the position of the protrusion member 61, and the tip of the protrusion member 61 is fitted into the groove M. Can do.

なお、第三部材５０側のラッチ機構６０は、第一部材３０のラッチ機構６０と同一構成であり、第三部材５０の格納孔５４は、当該格納孔５４から周面部５２内に突出する突起部材６１の先端部が挿通部２２内のトロリ線Ｔの所定の一方の凹溝Ｍに嵌合したときに、二つの凹溝Ｍが共にトロリ線Ｔにおける上部となるように、配置が決められている。
これらによって、各挿通部２１，２２において、二本のトロリ線の向きを適正に揃えることができる。 The latch mechanism 60 on the third member 50 side has the same configuration as the latch mechanism 60 of the first member 30, and the storage hole 54 of the third member 50 is a protrusion protruding from the storage hole 54 into the peripheral surface portion 52. The arrangement is determined such that when the tip of the member 61 is fitted into one predetermined groove M of the trolley wire T in the insertion portion 22, the two grooves M are both upper portions of the trolley wire T. ing.
By these, in each insertion part 21 and 22, the direction of two trolley lines can be arranged appropriately.

［連結機構］
連結機構７０は、第一部材３０の支持ブロック３６により回動可能に支持されたレバー７１と、レバー７１の回動端部に装備されたストッパー７２とから主に構成されている。
レバー７１は、前述したように、その基端部が支持ブロック３６の溝３６１の内側において、前後方向に沿った軸回りに回動可能に支持されており、その回動端部には雄ネジが形成されている。
そして、ストッパー７２は、中心が貫通して、その内側にレバー７１の回動端部の雄ネジに螺合する雌ネジが形成れている。このストッパー７２は、円筒部７２１と作業者が手で回転を加えるためのグリップ部７２２とが例えば樹脂により一体的に形成された部材である。 [Coupling mechanism]
The coupling mechanism 70 mainly includes a lever 71 that is rotatably supported by the support block 36 of the first member 30, and a stopper 72 that is provided at the rotating end of the lever 71.
As described above, the lever 71 is supported so that the base end portion thereof is rotatable around the axis along the front-rear direction inside the groove 361 of the support block 36, and the rotation end portion is provided with a male screw. Is formed.
The stopper 72 penetrates the center, and a female screw is formed on the inner side of the stopper 72 to be engaged with the male screw at the rotating end of the lever 71. The stopper 72 is a member in which a cylindrical portion 721 and a grip portion 722 for an operator to rotate by hand are integrally formed of resin, for example.

連結機構７０のレバー７１は、各挿通部２１，２２の拘束状態において、図１における二点鎖線の状態から、回動させてレバー７１を連結ブロック５６の溝５６１内に挿入することで、ストッパー７２の円筒部７２１の端面が連結ブロック５６の右側面に圧接した状態となり、各挿通部２１，２２の拘束状態を維持するように第一部材３０，第二部材４０，第三部材５０を固定的に連結する。
なお、ストッパー７２は、樹脂製であり、多少の弾性を有するので、レバー７１に対して回転させて位置調節することにより、連結ブロック５６に対する圧接力を調節することができる。 The lever 71 of the coupling mechanism 70 is a stopper by inserting the lever 71 into the groove 561 of the coupling block 56 by rotating from the two-dot chain line state in FIG. 72, the end surface of the cylindrical portion 721 is in pressure contact with the right side surface of the connecting block 56, and the first member 30, the second member 40, and the third member 50 are fixed so as to maintain the restrained state of the insertion portions 21 and 22. Are connected.
The stopper 72 is made of resin and has some elasticity. Therefore, the stopper 72 can be adjusted by rotating the lever 71 and adjusting the position thereof.

また、前述した第一部材３０と第三部材５０は、間に第二部材４０を挟む配置であり、第一部材３０側の支持ブロック３６に支持されたレバー７１及びストッパー７２を第三部材５０側の連結ブロック５６に掛け渡して連結する構造なので、一つのレバー７１の一回の回動操作のみで三つの部材３０，４０，５０を介して二本のトロリ線Ｔを同時に拘束状態に保持することができ、作業性を向上させることができる。   Further, the first member 30 and the third member 50 described above are arranged with the second member 40 interposed therebetween, and the lever 71 and the stopper 72 supported by the support block 36 on the first member 30 side are provided with the third member 50. Since it is connected to the connecting block 56 on the side, the two trolley wires T are simultaneously held in a restrained state via the three members 30, 40, 50 by only one turning operation of one lever 71. It is possible to improve workability.

［トロリ線に対するダブルイヤーの取り付け作業］
図６に基づいてトロリ線Ｔに対するダブルイヤー２００の取り付け作業について説明する。
連結する前の二本のトロリ線Ｔがいずれも捻れを生じて不適正な向きを向いている状態において（図６（Ａ））、挿通部２１，２２をいずれも解放状態としたトロリ線ねじれ直し工具１０を装着する（図６（Ｂ）、図５）。即ち、第二部材４０の仕切り壁部４２を二本のトロリ線Ｔの間に介挿するようにして、各トロリ線Ｔを挿通部２１，２２に個別に格納する。 [Installation work of double ear to trolley wire]
The operation of attaching the double ear 200 to the trolley wire T will be described with reference to FIG.
In a state where the two trolley wires T before being connected are twisted and are oriented in an inappropriate direction (FIG. 6A), the trolley wire twist in which the insertion portions 21 and 22 are both released. The repair tool 10 is mounted (FIGS. 6B and 5). That is, each trolley wire T is individually stored in the insertion portions 21 and 22 such that the partition wall portion 42 of the second member 40 is interposed between the two trolley wires T.

そして、第一部材３０と第三部材５０とを第二部材４０側に回動させて拘束状態とし、連結機構７０のレバー７１を回動させて拘束状態を保持する状態にする（図６（Ｃ））。
この時、各挿通部２１，２２内では、各トロリ線Ｔはいずれも向きが不適正な方向を向いているので、凹溝Ｍと突起部材６１とが合致せず、各突起部材６１はトロリ線Ｔにより退避位置に押し戻された状態となっている。 Then, the first member 30 and the third member 50 are rotated to the second member 40 side to be in a restrained state, and the lever 71 of the coupling mechanism 70 is rotated to be in a state in which the restrained state is maintained (FIG. 6 ( C)).
At this time, since each trolley wire T is in an inappropriate direction in each insertion portion 21, 22, the groove M and the projection member 61 do not match, and each projection member 61 The line T is pushed back to the retracted position.

そこで、トロリキー２１０（図１２参照）により、一方のトロリ線Ｔを回動させ、所定の凹溝Ｍに突起部材６１を嵌合させる（図６（Ｄ））。
同様に、もう一方のトロリ線Ｔを回動させ、所定の凹溝Ｍに突起部材６１を嵌合させる（図６（Ｅ））。
なお、図６では挿通部２２のトロリ線Ｔから先に向き調整を行っているが、挿通部２１，２２のいずれから先に行っても良い。 Therefore, one trolley wire T is rotated by the trolley key 210 (see FIG. 12), and the protruding member 61 is fitted into the predetermined groove M (FIG. 6D).
Similarly, the other trolley wire T is rotated, and the protruding member 61 is fitted into the predetermined groove M (FIG. 6E).
In FIG. 6, the orientation adjustment is performed first from the trolley line T of the insertion portion 22, but may be performed first from either of the insertion portions 21 and 22.

これにより、二本のトロリ線Ｔはいずれも二本の凹溝Ｍが上部に位置する適正な向きで保持され、また、各トロリ線Ｔは互いに近接して同じ高さで水平に並んだ状態で保持することができる（図６（Ｆ））。
かかる状態において、ダブルイヤー２００を二本のトロリ線Ｔに取り付ける。この時、図９〜図１１に示すように、二本のトロリ線Ｔが隣り合って並んだ範囲に複数のダブルイヤー２００を取り付けても良い。
また、各トロリ線Ｔの接続端部の先端部は、図１０に示すように、車両のパンタグラフとの干渉を生じないように、専用の工具を使用して斜め上方に湾曲させる。 As a result, the two trolley lines T are both held in an appropriate orientation in which the two concave grooves M are located at the top, and the trolley lines T are arranged in the horizontal direction at the same height close to each other. (FIG. 6F).
In this state, the double ear 200 is attached to the two trolley wires T. At this time, as shown in FIGS. 9 to 11, a plurality of double ears 200 may be attached in a range where two trolley wires T are arranged next to each other.
Further, as shown in FIG. 10, the tip end portion of the connecting end portion of each trolley wire T is bent obliquely upward using a dedicated tool so as not to interfere with the pantograph of the vehicle.

そして、ダブルイヤー２００の取り付けが終わると、レバー７１を下方に回動させてストッパー７２を連結ブロック５６から外し、第一部材３０及び第三部材５０を第二部材４０から離間する方向に回動させる（図６（Ｇ）、図５）。これにより、各挿通部２１，２２が解放状態となり、内部のトロリ線Ｔを外部に取り出すことができる。
このとき、各トロリ線Ｔからトロリ線ねじれ直し工具１０を取り外す際に、第二部材４０の下端部に位置する仕切り壁部４２が左右方向に一定の幅となっているので、ダブルイヤー２００により近接状態で連結された二本のトロリ線Ｔの間から容易に引き抜くことができ、トロリ線ねじれ直し工具１０を容易に取り外すことができる。 When the attachment of the double ear 200 is completed, the lever 71 is rotated downward to remove the stopper 72 from the connection block 56, and the first member 30 and the third member 50 are rotated away from the second member 40. (FIG. 6G, FIG. 5). Thereby, each insertion part 21 and 22 will be in a release state, and the inside trolley wire T can be taken out outside.
At this time, when removing the trolley wire twisting tool 10 from each trolley wire T, the partition wall portion 42 located at the lower end portion of the second member 40 has a constant width in the left-right direction. The two trolley wires T connected in close proximity can be easily pulled out, and the trolley wire twisting tool 10 can be easily removed.

［トロリ線に対するダブルイヤーの他の取り付け作業］
トロリ線Ｔに対するダブルイヤー２００の取り付け作業については他の方法でも行うことができる。
図７に基づいてトロリ線Ｔに対するダブルイヤー２００の他の取り付け作業について説明する。
連結する前の二本のトロリ線Ｔがいずれも捻れを生じて不適正な向きを向いている状態において（図７（Ａ））、一方のトロリ線Ｔの凹溝Ｍに挿通部２２の突起部材６１が嵌合するようにトロリ線ねじれ直し工具１０を傾けた状態で当該トロリ線ねじれ直し工具１０を装着する（図７（Ｂ））。
なお、二本のトロリ線Ｔのいずれにトロリ線ねじれ直し工具１０の向きを合わせても良いが、ここでは、挿通部２２に格納するトロリ線Ｔに向きを合わせる場合を例示する。 [Other installation work of double ear to trolley wire]
The operation of attaching the double ear 200 to the trolley wire T can be performed by other methods.
Based on FIG. 7, another attaching operation of the double ear 200 to the trolley wire T will be described.
In a state where the two trolley wires T before being connected are twisted and are oriented in an inappropriate direction (FIG. 7A), the projection of the insertion portion 22 is inserted into the groove M of the one trolley wire T. The trolley wire twisting tool 10 is mounted with the trolley wire twisting tool 10 tilted so that the member 61 is fitted (FIG. 7B).
In addition, although the direction of the trolley wire twisting tool 10 may be adjusted to any of the two trolley wires T, here, a case where the direction is adjusted to the trolley wire T stored in the insertion portion 22 is illustrated.

そして、第一部材３０と第三部材５０とを第二部材４０側に回動させて拘束状態とし、連結機構７０のレバー７１を回動させて拘束状態を保持する状態にする（図７（Ｃ））。
そして、トロリ線ねじれ直し工具１０を水平となる向きに回動させることにより、挿通部２２内のトロリ線Ｔも回動させて向きを適正化する（図７（Ｄ））。 Then, the first member 30 and the third member 50 are turned to the second member 40 side to be in a restrained state, and the lever 71 of the coupling mechanism 70 is turned to be in a state to hold the restrained state (FIG. 7 ( C)).
Then, by rotating the trolley wire retwisting tool 10 in a horizontal direction, the trolley wire T in the insertion portion 22 is also rotated to optimize the direction (FIG. 7D).

さらに、トロリキー２１０により、もう一方のトロリ線Ｔを回動させ、所定の凹溝Ｍに突起部材６１を嵌合させる（図７（Ｅ））。
これにより、二本のトロリ線Ｔはいずれも二本の凹溝Ｍが上部に位置する適正な向きで保持され、また、各トロリ線Ｔは互いに近接して同じ高さで水平に並んだ状態で保持することができる（図７（Ｆ））。 Further, the other trolley wire T is rotated by the trolley key 210, and the protruding member 61 is fitted into the predetermined groove M (FIG. 7E).
As a result, the two trolley lines T are both held in an appropriate orientation in which the two concave grooves M are located at the top, and the trolley lines T are arranged in the horizontal direction at the same height close to each other. (FIG. 7F).

この状態でダブルイヤー２００を取り付け、各トロリ線Ｔからトロリ線ねじれ直し工具１０を取り外すことにより作業が完了する（図７（Ｇ））。
この図７の方法では、一方のトロリ線Ｔはトロリ線ねじれ直し工具１０と共に回動させて捻れを解消させるので、トロリキー２１０によるトロリ線Ｔの回動作業を片方のみに対して行えば良く、より効率的且つ迅速にダブルイヤー２００の取り付け作業を行うことができる。 In this state, the double ear 200 is attached, and the trolley wire twisting tool 10 is removed from each trolley wire T to complete the work (FIG. 7G).
In the method of FIG. 7, one trolley wire T is rotated together with the trolley wire twisting tool 10 to eliminate the twist, and therefore, the rotation operation of the trolley wire T by the trolley key 210 may be performed only on one side. The double ear 200 can be attached more efficiently and quickly.

［発明の実施形態の技術的効果］
トロリ線ねじれ直し工具１０は、工具本体２０を第一〜第三複数３０，４０，５０から構成して、二つの挿通部２１，２２内のトロリ線Ｔの拘束状態と解放状態の切り替えを可能とし、挿通部２１，２２の内側に、二本のトロリ線Ｔの凹溝Ｍの位置が揃うように凹溝Ｍに嵌まる突起部材６１を設けると共に、各突起部材６１を押し込み可能であってコイルバネ６２により突出方向に押圧する構成としている。
このため、各挿通部２１，２２内に拘束した状態で各トロリ線Ｔの捻れを直す作業を行うことができ、ダブルイヤー２００を取り付ける際にも、各トロリ線Ｔは近接して並んだ状態で向きも適正に保持された状態を維持することができ、トロリ線を適正な位置に保持する作業者や捻れを適正な位置に保持する作業者を不要とし、単独の作業者によるダブルイヤー２００の取り付け作業が可能となり、また、作業の容易化により作業時間の短縮化を図ることが可能となる。 [Technical effects of the embodiment of the invention]
The trolley wire retwisting tool 10 comprises a tool body 20 composed of first to third pluralities 30, 40, 50, and can switch between a restrained state and a released state of the trolley wire T in the two insertion portions 21, 22. Protruding members 61 that fit into the recessed grooves M so that the positions of the recessed grooves M of the two trolley wires T are aligned are provided inside the insertion portions 21 and 22, and each protruding member 61 can be pushed in. The coil spring 62 is pressed in the protruding direction.
For this reason, the operation | work which corrects the twist of each trolley line T in the state restrained in each insertion part 21 and 22 can be performed, and when attaching the double ear 200, each trolley line T is located in the vicinity Therefore, it is possible to maintain a state in which the orientation is properly held, and an operator who holds the trolley wire in an appropriate position and an operator that holds the twist in an appropriate position are unnecessary, and the double ear 200 by a single operator is used. It is possible to reduce the work time by facilitating the work.

また、工具本体２０を第一部材３０と第二部材４０と第三部材５０とから構成したので、第二部材４０に対する第一部材３０の回動と第二部材４０に対する第三部材５０の回動とにより、二つの挿通部２１，２２内のトロリ線Ｔの拘束状態と解放状態の切り替えを容易に行うことが可能となる。
また、第一部材３０及び第三部材５０は、第二部材４０に対して、回動端部が接近又は離間するので、二本のトロリ線Ｔが互いに離れている場合でも、第一部材３０及び第三部材５０が第二部材４０側に引き寄せて各挿通部２１，２２に格納させることができ、トロリ線Ｔに対するトロリ線ねじれ直し工具１０の取り付けを容易に行うことができる。 Further, since the tool body 20 is composed of the first member 30, the second member 40, and the third member 50, the rotation of the first member 30 relative to the second member 40 and the rotation of the third member 50 relative to the second member 40 are performed. By the movement, it becomes possible to easily switch between the restrained state and the released state of the trolley wire T in the two insertion portions 21 and 22.
In addition, since the first member 30 and the third member 50 have the rotating end portion approaching or separating from the second member 40, the first member 30 even when the two trolley wires T are separated from each other. And the 3rd member 50 can be drawn near to the 2nd member 40 side, and can be stored in each insertion part 21 and 22, and the attachment of the trolley wire twisting tool 10 with respect to the trolley wire T can be performed easily.

また、第一部材３０と第二部材４０と第三部材５０とは、回動軸２３，２４により回動可能に連結されているので、拘束状態、解放状態に拘わらず、工具本体２０が一体化され、作業時における各部材３０〜５０の落下や紛失の発生を低減することができ、作業性の向上を図ることが可能となる。   Further, since the first member 30, the second member 40, and the third member 50 are rotatably connected by the rotation shafts 23 and 24, the tool body 20 is integrated regardless of the restrained state or the released state. Therefore, it is possible to reduce the occurrence of dropping or loss of the respective members 30 to 50 at the time of work, and it is possible to improve workability.

また、トロリ線ねじれ直し工具１０は、二つの挿通部２１，２２内のトロリ線Ｔの拘束状態を維持するように、第一〜第三部材３０〜５０を保持する連結機構７０を備え、当該連結機構７０は、第一部材３０に設けられ、第三部材５０に設けられた溝５６１に対して、回動により嵌合するレバー７１と、レバー７１の回動端部に設けられ、回転操作により位置調節可能なストッパー７２とを備えている。これにより、レバー７１の回動動作とストッパー７２の回転操作により、各挿通部２１，２２が拘束状態を維持するように第一〜第三部材３０〜５０を保持することができ、二本のトロリ線Ｔにトロリ線ねじれ直し工具１０を取り付ける作業を容易且つ迅速に行うことが可能となる。
また、連結機構７０をレバー７１とストッパー７２とから構成したので、連結機構７０を工具本体２０に一体的に連結することができ、分離した部材が存在せず、作業性の向上を図ることが可能となる。さらに、連結機構７０の各構成の落下や紛失の発生を低減することが可能となる。 The trolley wire retwisting tool 10 includes a coupling mechanism 70 that holds the first to third members 30 to 50 so as to maintain the restrained state of the trolley wire T in the two insertion portions 21 and 22. The coupling mechanism 70 is provided on the first member 30, and is provided on the lever 71 that rotates and fits in the groove 561 provided on the third member 50, and the rotation end of the lever 71. And a stopper 72 whose position can be adjusted. As a result, the first to third members 30 to 50 can be held so that the insertion portions 21 and 22 are maintained in a restrained state by the rotation operation of the lever 71 and the rotation operation of the stopper 72. The operation of attaching the trolley wire twisting tool 10 to the trolley wire T can be performed easily and quickly.
In addition, since the connecting mechanism 70 is composed of the lever 71 and the stopper 72, the connecting mechanism 70 can be integrally connected to the tool body 20, and there is no separate member, thereby improving workability. It becomes possible. Furthermore, it is possible to reduce the occurrence of dropping or loss of each component of the coupling mechanism 70.

［工具本体の他の例］
トロリ線ねじれ直し工具１０の工具本体２０は三つの部材３０，４０，５０から構成されているが、部材の数は、複数であれば良く、三つに限定されない。
図８に、工具本体を第一部材３０Ａと第二部材４０Ａの二部材から構成した例を示す。この例において、前述したトロリ線ねじれ直し工具１０と同一の構成については同符号を付して重複する説明は省略する。 [Other examples of tool body]
Although the tool body 20 of the trolley wire retwisting tool 10 is composed of three members 30, 40, 50, the number of members may be plural, and is not limited to three.
FIG. 8 shows an example in which the tool body is composed of two members, a first member 30A and a second member 40A. In this example, the same components as those of the trolley wire retwisting tool 10 described above are denoted by the same reference numerals, and redundant description is omitted.

この工具本体は、第一部材３０Ａと第二部材４０Ａとを互いの一端部で回動可能に連結し、
第二部材４０Ａにおける第一部材３０Ａとの対向部分に一つの凹溝からなる挿通部２１，２２を形成し、第一部材３０Ａにおける第二部材４０Ａとの対向部分に凹溝内を二つの挿通部２１，２２に仕切る凸部を設けている。
また、各挿通部２１，２２内で適正な向きのトロリ線Ｔの凹溝Ｍに突起部材６１が嵌合するように第二部材４０Ａには二つのラッチ機構６０が設けられている。さらに、第一部材３０Ａと第二部材４０Ａの互いの回動端部を連結するように連結機構７０が設けられている。 This tool body connects the first member 30A and the second member 40A so as to be rotatable at one end of each other,
Insertion portions 21 and 22 made of one concave groove are formed in a portion of the second member 40A facing the first member 30A, and two portions of the first member 30A are inserted through the concave groove in a portion of the first member 30A facing the second member 40A. Protrusions that partition the parts 21 and 22 are provided.
In addition, two latch mechanisms 60 are provided on the second member 40A so that the protruding member 61 is fitted in the concave groove M of the trolley wire T in an appropriate direction in each of the insertion portions 21 and 22. Further, a connecting mechanism 70 is provided so as to connect the rotating end portions of the first member 30A and the second member 40A.

このように工具本体を二部材で構成したトロリ線ねじれ直し工具の場合には、前述したトロリ線ねじれ直し工具１０のように、二本のトロリ線Ｔを引き寄せて各挿通部２１，２２内に格納することはできないが、構造の簡略化と部材数の低減を図ることができ、工具の製造コストの低減を図ることが可能である。   Thus, in the case of the trolley wire retwisting tool in which the tool body is composed of two members, as in the trolley wire retwisting tool 10 described above, the two trolley wires T are attracted and inserted into the insertion portions 21 and 22. Although it cannot be stored, the structure can be simplified and the number of members can be reduced, and the manufacturing cost of the tool can be reduced.

［その他］
また、トロリ線ねじれ直し工具１０では、各挿通部２１，２２内の突起部としての突起部材６１は、いずれも背圧を受けて進退可能に配置されているが、いずれか一方の突起部については、進退移動せずに固定的に設けても良い。このように、一方の突起部を固定した場合には、ダブルイヤー２００の取り付けは、図７の方法で行う。
即ち、図７（Ｂ）の工程で、固定された突起部が、捻れを生じた一方のトロリ線Ｔの凹溝Ｍに嵌合するように、トロリ線ねじれ直し工具１０を傾けて取り付けを行う。そして、これ以降は、前述した図７の各工程と同じである。 [Others]
Further, in the trolley wire retwisting tool 10, the protruding members 61 as the protruding portions in the respective insertion portions 21 and 22 are arranged so as to be able to advance and retract under the back pressure. May be fixedly provided without moving forward or backward. In this way, when one of the protrusions is fixed, the double ear 200 is attached by the method of FIG.
That is, in the process of FIG. 7B, the trolley wire retwisting tool 10 is tilted and attached so that the fixed protrusion is fitted into the concave groove M of one trolley wire T that has been twisted. . The subsequent steps are the same as those in FIG. 7 described above.

また、連結機構７０は、一つの機構で第一〜第三部材３０，４０，５０の全てを同時連結可能なものを例示したが、これに限らない。
例えば、第一部材３０と第二部材４０の連結を行う連結機構と第二部材４０と第三部材５０の連結を行う連結機構とを個別に設けてもよい。
この場合、トロリ線ねじれ直し工具１０の取り付けの際に作業が一つ増えることになるが、トロリ線Ｔを一本ずつ拘束することができるので、二本のトロリ線Ｔを同時に拘束する場合よりも少ない力でトロリ線ねじれ直し工具１０の取り付け作業を行うことができる。 Moreover, although the connection mechanism 70 illustrated what can connect all the 1st-3rd members 30,40,50 simultaneously by one mechanism, it is not restricted to this.
For example, a connecting mechanism that connects the first member 30 and the second member 40 and a connecting mechanism that connects the second member 40 and the third member 50 may be provided separately.
In this case, when the trolley wire retwisting tool 10 is attached, the work is increased by one. However, since the trolley wire T can be restrained one by one, the two trolley wires T are restrained at the same time. The trolley wire retwisting tool 10 can be attached with less force.

また、ラッチ機構６０の突起部材６１は、トロリ線Ｔの予定しない方の凹溝Ｍに間違って嵌合させてしまう場合もあり得るので、工具本体２０の外部から突起部材６１を後退させる操作部を設けてもよい。これにより、突起部材６１を後退させて、トロリ線Ｔの回動作業をやり直すことが可能となる。
また、突起部材６１をトロリ線Ｔの予定しない方の凹溝Ｍに嵌合させてしまうことの対策として、突起部材６１を外部操作可能なストッパーで後退状態に維持可能とし、トロリ線Ｔを回動させて適正な向きであることを確認してから工具本体２０の外部から解除操作を行い、突起部材６１を突出させる構成を設けてもよい。 Further, since the projection member 61 of the latch mechanism 60 may be erroneously fitted into the groove M of the trolley wire T that is not planned, the operation unit that retracts the projection member 61 from the outside of the tool body 20. May be provided. As a result, the protruding member 61 can be retracted and the trolley wire T can be rotated again.
Further, as a countermeasure against fitting the protruding member 61 into the groove M of the trolley wire T which is not planned, the protruding member 61 can be maintained in a retracted state by a stopper which can be externally operated, and the trolley wire T is rotated. A configuration may be provided in which the protruding member 61 is protruded by performing a release operation from the outside of the tool body 20 after confirming that it is in the proper orientation.
