【考案の詳細な説明】 本考案は、電車線を吊架するバンガーイヤーにおける楔
金具の抜は出しを阻止して電車線とバンガーイヤーが離
脱しないようにした装置に関するものである。[Detailed Description of the Invention] The present invention relates to a device that prevents the banger ear from separating from the overhead contact line by preventing the wedge fitting from being removed from the banger ear for suspending the overhead contact line.

電車線はバンガーイヤーの挟持金具により挾し吊下され
、この挟持金具は楔片により挟持状態を維持しているが
、電車の頻繁な通過による電車線の振動等によって、楔
片が徐々に抜は出し挟持金具が緩んで電車線から離脱し
架線事故を招くことが多かった。The overhead contact wire is suspended by the clamping brackets of banger ears, and the clamping brackets are maintained in a clamped state by wedge pieces, but due to vibrations of the overhead contact line due to frequent passing of trains, the wedge pieces gradually become detached. The protruding clamping fittings often loosened and separated from the overhead contact line, resulting in catenary line accidents.

このため楔片の抜は出しを防止する種々の手段が用いら
れて来たが、これらは保合突起等により楔片を係合させ
、その抜は出しを訪いでいるので、電車線の振動により
保合が外れることがあり、楔片の抜は出しを確実に防止
することはできなかった。For this reason, various means have been used to prevent the wedge pieces from coming out, but these methods engage the wedge pieces with retaining protrusions, etc., and prevent the wedge pieces from coming out. This could cause the wedge to become unlatched, and it was not possible to reliably prevent the wedge piece from coming out.

本考案は、前述の点に鑑み、バンガーイヤーの挾持金具
から楔片が抜は出ることのない安全な装置を提供するも
のであり、以下にその構成を図面により説明する。In view of the above-mentioned points, the present invention provides a safe device that prevents the wedge piece from coming out from the banger ear clip, and the configuration thereof will be explained below with reference to the drawings.

第１図は本考案の抜は止め具を示し、プラスチック製の
コ字型体の上板部１にはその先端に下方に突出する係止
突起２を設け、下板部３はその先端の上面を斜面４に形
成したものである。Fig. 1 shows the removal stopper of the present invention, in which an upper plate part 1 of a U-shaped plastic body is provided with a locking protrusion 2 projecting downward at its tip, and a lower plate part 3 is provided with a locking protrusion 2 at its tip. The upper surface is formed into a slope 4.

第２図乃至第４図は前記の止め具をバンガーイヤーに装
着した状態を示し、バンガーイヤーは第２図、第４図示

車線挟持爪７，８を設は両挾持片を軸９により結合した
挾持金具１０と両挾持具上端間の楔金具１１とよりなる
ものである。Figures 2 to 4 show the above-mentioned stopper attached to the banger ear, and the banger ear is attached to each lower end of a pair of opposing clamping pieces 5 and 6, as shown in Figures 2 and 4. The contact wire clamping claws 7 and 8 are comprised of a clamping bracket 10 in which both clamping pieces are connected by a shaft 9, and a wedge bracket 11 between the upper ends of both clamping fixtures.

楔金具は第３図点線図示のように細長環状を呈し、その
上片１２と下片１３間の空所１４に挾持金具５゜６の上
部の突部１５，１６を位置させ挟持金具下端の両挾持爪
７，８で電車線Ｔを挾持し、両挾持金具の上端の対向面
間に楔金具を押し込むことによって電車線の挟持が緩ま
ないようにしており、このとき楔金具の先端は第３図示
のように挟持金具の端面から側方に突出している。The wedge fitting has an elongated annular shape as shown by the dotted line in FIG. The contact wire T is held between the two clamping claws 7 and 8, and the wedge fitting is pushed between the opposing surfaces of the upper ends of both clamping fittings to prevent the contact wire from loosening. At this time, the tip of the wedge fitting is 3. As shown in Figure 3, it protrudes laterally from the end surface of the clamping fitting.

なお１７は楔金具が挟持金具から分離するのを防止する
ためのピンであり、１８はバンガー先端の掛止孔である
。Note that 17 is a pin for preventing the wedge fitting from separating from the clamping fitting, and 18 is a latching hole at the tip of the banger.

前記のように電車線を挾持した挟持金具の端面から側方
に突出した楔金具の先端部に前記の抜は止め具を装着す
る。The above-mentioned removal stopper is attached to the tip of the wedge fitting that protrudes laterally from the end face of the clamping fitting that clamps the overhead contact wire as described above.

該抜は止め具はプラスチック製であり若干の弾力を有す
るので、上板部１と下板部３の先端を楔金具先端の上片
１２の側面に当てがい強く押し込めば、第４図示のよう
に上片１２は上板部１と下板部３の間に挾まれ、上板部
１の先端の係止突起２が楔金具上片１２の側縁に係止さ
れて装着されるのである。The removal stopper is made of plastic and has some elasticity, so if you place the tips of the upper plate part 1 and the lower plate part 3 against the side of the upper piece 12 at the tip of the wedge metal fitting and push it firmly, it will come out as shown in Figure 4. The upper piece 12 is sandwiched between the upper plate part 1 and the lower plate part 3, and the locking protrusion 2 at the tip of the upper plate part 1 is locked to the side edge of the upper piece 12 of the wedge fitting. .

本考案の装置は前述のように構威し、抜は止め具の下板
部３はその先端上面が斜面となっているので、楔金具の
上片を上板部１と下板部３の先端に挾んで抜は止め具を
押し込むときは該斜面が楔金具上片の縁に当っても阻止
されることなく滑って進むことができ、また抜は止め具
はプラスチック製で弾力を有するので上板部１と下板部
３を楔金具に押し込むときに両板部が弾力的に開いて押
し込み易く、そして上板部１の先端には係止突起２が設
けてあり、これが楔金具の側縁に係止されているので電
車線やハンガーイヤーが振動しても抜は止め具が楔金具
から外れることがない。The device of the present invention is constructed as described above, and since the upper surface of the tip of the lower plate part 3 of the removal stopper is sloped, the upper part of the wedge fitting is connected between the upper plate part 1 and the lower plate part 3. When holding the tip and pushing in the pull-out stopper, it can slide forward without being blocked even if the slope hits the edge of the upper piece of the wedge metal fitting, and since the pull-out stopper is made of plastic and has elasticity. When pushing the upper plate part 1 and the lower plate part 3 into the wedge fitting, both plate parts open elastically and are easy to push in, and a locking protrusion 2 is provided at the tip of the upper plate part 1, which locks the wedge fitting. Since it is locked to the side edge, the removal stopper will not come off from the wedge fitting even if the overhead contact line or hanger ears vibrate.

このように楔金具の先端部には抜は止め具が装着される
ので、電車の頻繁な通過によりハンガーイヤーが激しく
振動して楔金具が挟持金具から抜は出ようとしても、抜
は止め具の側面が挾持金具の端面に当接して楔金具の抜
は出しを阻止し、その結果電車線Ｔを挟持している挾持
片５，６の挾持が緩むことなく、ハンガーイヤーが電車
線がら離脱することが防止されるのである。In this way, the removal stopper is attached to the tip of the wedge metal fitting, so even if the hanger ear vibrates violently due to the frequent passing of trains and the wedge metal fitting tries to come out from the clamping metal fitting, the removal stopper will not stop. The sides of the clip come into contact with the end face of the clip and prevent the wedge from being pulled out, and as a result, the clips 5 and 6 holding the overhead contact line T do not loosen, and the hanger ear separates from the contact wire. This prevents them from doing so.

そして、前記後は止め具はプラスチック製なので着色す
ることができ、これを黒色等に着色しておくことにより
地上からハンガーイヤーの状況を監視し易く、軽量なの
で電車線に重量負担をがけることもないものであり、こ
のように、本考案によればハンガーイヤーの離脱が確実
に防止できるので、架線事故の発生防止に極めて有効な
ものである。Since the stopper after the above is made of plastic, it can be colored.By coloring it black etc., it is easier to monitor the situation of the hanger ear from the ground, and since it is lightweight, it does not burden the overhead contact line. Thus, according to the present invention, detachment of the hanger ear can be reliably prevented, and therefore it is extremely effective in preventing the occurrence of catenary accidents.
