Description
この発明は、鉄道の電線路に生じる誘導電流又は大電流を大地に落とすため、レールに取り付ける接地金具に関するものである。 The present invention relates to a grounding metal fitting attached to a rail in order to drop an induced current or a large current generated in a railway electric wire to the ground.
現在の鉄道軌道用接地金具は、図９に示すように、レール５１の底面とバラスト５２の上面との間に接地金具５０の一端５０ａを通し、その一端５０ａの鉤部５３をレール５１の一側に引っ掛け、他端５０ｂの係止片５４をレール５１の他側に係止し、この係止片５４を締め付け具５５で強固に締め付けているものが使用されている。
しかしながら、近年、鉄道の敷設後の保守作業の軽減と安全性からバラストの散乱防止や振動防止のため、バラストをセメント系てん充材で固めている省力化軌道を採用している。この省力化軌道は、大地とレール底面部との間に隙間がない。それ故、上記図９のような接地金具５０は使用できない。
As shown in FIG. 9, the current railroad track grounding metal fitting passes one end 50 a of the grounding metal 50 between the bottom surface of the rail 51 and the top surface of the ballast 52, and the flange 53 of the one end 50 a is connected to the rail 51. The locking piece 54 of the other end 50 b is locked to the other side of the rail 51, and the locking piece 54 is firmly tightened with a tightening tool 55.
However, in recent years, a labor-saving track has been adopted in which ballast is hardened with cement-based fillers in order to reduce ballast scattering and prevent vibrations in order to reduce maintenance work after railway construction and to ensure safety. This labor-saving track has no gap between the ground and the bottom of the rail. Therefore, the grounding metal fitting 50 as shown in FIG. 9 cannot be used.
そこで、図１０に示すように、レール底面部と大地との間に接地金具を通さずにレールの左右のどちらか一方の片側で固定できる接地金具が開発された。これは、レール６０の底辺両側を側板６１で挟持して平坦な床面に定置されたレール６０において、直方体上面にねじ孔を穿ち下面に上記側板６１の端縁と係合可能に三角切り込みを持たせた下ブロック６２と、下端部で上記ねじ孔と螺合し上端部に大径鍔とスパナ掛けを設けた支持ボルト６３と、下面に穿った凹みで支持ボルト６３の上端部へ若干首振り可能に被挿されかつ抜止めされた上ブロック６４と当該上ブロック６４の側面に固着された接地線用圧着端子６５とから構成され、上記下ブロック６２を側板６１の端縁に係合させ支持ボルト６３の回動により上ブロック６４をレール６０の頭と脚辺の境界部に押圧するようにしたものである。
しかしながら、上記図１０のものは、支持ボルト６３を回して上ブロック６４と下ブロック６２をレール６０の頭と脚辺の境界部及び側板６１の端縁にそれぞれ圧着させるが、上下ブロック６４及び６２の間隔を調整する支持ボルト６３を直接回して締めあげる作業のため相当の力が必要であり、またレール脇の狭い場所で支持ボルト６３の締め上げ作業のため、作業しずらく、また不完全な締め付けとなり、接地金具が取れ易いおそれもある。また、下ブロック６２はブロックの下面に三角切り込みを入れた形状のため側板６１の端縁にしか取り付けできず、汎用性がない。 However, in FIG. 10, the support bolt 63 is rotated to crimp the upper block 64 and the lower block 62 to the boundary between the head and leg sides of the rail 60 and the edge of the side plate 61, respectively. A considerable amount of force is required for the work of directly tightening and tightening the support bolts 63 for adjusting the distance between them, and the work is difficult and incomplete because of the work of tightening the support bolts 63 in a narrow place beside the rail. Tightening and the grounding bracket may be easily removed. Further, since the lower block 62 has a shape in which a triangular notch is formed on the lower surface of the block, it can be attached only to the edge of the side plate 61 and is not versatile.
そこで、この発明は、レール底面部と大地との間に接地金具を通さずにレールの左右のどちらか一方の片側で取り付けられるタイプの接地金具において、レールへの取り付けが極めて容易で、かつ多数種のレール締結金具箇所で取り付けられる汎用性のある接地金具を提供しようとするものである。 Therefore, the present invention is a type of grounding metal fitting that is attached to either one of the left and right sides of the rail without passing the grounding metal between the bottom surface of the rail and the ground. The purpose of this invention is to provide a versatile grounding bracket that can be mounted at various types of rail fastening brackets.
請求項１の発明は、レールの一側の顎部に導電性材料から成る接地金具の一端を当接させ、前記導電性材料の一端のほぼ延長線上に位置する接地金具の他端を、レール締結装置に係止させ、この接地金具の一端と他端とをそれぞれ外方に突っ張らせる手段を設けて、レールの一側に固定する構成とし、上記接地金具の一端がＴ字型であって、レールとの当接部がほぼ蒲鉾形状となり、当該Ｔ字型の接地金具のレール当接面と並行方向の一端に、リード線端を圧縮固定可能とした接地端子を有し、上記接地金具の他端が先細状になっており、
また、上記外方に突っ張らせる手段が、一本のボルトの半分で左右ネジに分けられたボルトの一端に、当該ボルトを軸としたハンドルを設け、このボルトの左右ネジにそれぞれ一つのナットを螺着し、これらのナットはボルトの回転により、相互に離れたり、接近したりし、これらの各ナットに一端を回転自在に軸支した、リンク片を各ナットの両側にそれぞれ突出させ、各ナットの各一側において、二つのナットから突出した各リンク片の各他端を接地金具の一端又は他端にそれぞれ回転自在に軸支し、かつこの二つの各リンク片の他端に設けた歯車部を相互に噛み合わせ、上記二つのナットが相互に離れることにより接地金具の一端と他端の距離が短くなり、上記二つのナットが相互に接近することにより、接地金具の一端と他端の距離が長くなる構成とし、前記接地金具の一端と他端とを結ぶ直線に対し前記ボルトが直交している、軌道対応型接地金具とした。
The invention according to claim 1, one end of the grounding member formed of a conductive material to the jaws of the one side of the rail is brought into contact, the other end of the grounding member positioned substantially on an extension of one end of the conductive material, the rails The grounding bracket is fixed to one side of the rail by providing means for engaging one end and the other end of the grounding bracket outwardly, and fixing one end of the grounding bracket, and one end of the grounding bracket is T-shaped. The contact portion with the rail is substantially bowl-shaped, and has a ground terminal at one end in parallel to the rail contact surface of the T-shaped grounding fixture, and the lead wire end can be compressed and fixed. The other end is tapered,
Further, the means for extending outward is provided with a handle centered on the bolt at one end of the bolt divided into the left and right screws by a half of one bolt, and one nut for each of the left and right screws of the bolt. These nuts are separated from each other or approached by the rotation of the bolts, one end of each nut is rotatably supported, and the link pieces are protruded on both sides of each nut, On each side of each nut, each other end of each link piece protruding from the two nuts is rotatably supported on one end or the other end of the grounding metal fitting, and provided on the other end of each of these two link pieces. When the two nuts are separated from each other, the distance between one end and the other end of the grounding bracket is shortened, and when the two nuts are close to each other, one end of the grounding bracket and the other are Edge distance And longer construction, the relative straight line connecting the one end and the other end of the grounding metal bolts are orthogonal, and a track corresponding type grounding member.
請求項１の発明によれば、レール底面部と大地との間に接続金具を通さずに、取り付けができるので、レールの片側で作業が行える。従って、省力化軌道であっても、接地金具が取り付けられ、さらに従来のバラストの上に固定した軌道にも取り付けられる。従って、接地金具のレールへの取り付けが極めて容易かつ迅速に行え、作業性が良い。また、接地金具の一端がＴ字型になっているため、レールの顎部の下面に一定の長さのほぼ蒲鉾形状の棒を当接させ、先細形状の他端をレール締結装置の金具の間に突き刺すだけで係止させているため、これらを突っ張らせる際、接地金具を安定して取り付けることができる。また、このように接地金具の他端が先細形状になっているため、多数種のレール締結装置に係止することができる。また、前記突っ張らせる手段が、ハンドルを回すだけで、確実かつ容易に突っ張ったり、引っ込んだりでき、作業が容易である利点を有する。さらに、ハンドルを接地金具の一端と他端の方向に対して直角な側面に設けているため、特にハンドルを上向きに取り付けることができ、当該接地金具の取り付け操作が極めて容易となる。 According to the first aspect of the present invention, since the attachment can be performed without passing the connecting metal fitting between the rail bottom surface portion and the ground, the work can be performed on one side of the rail. Therefore, even if it is a labor-saving track | orbit, a grounding metal fitting is attached and it is further attached to the track | truck fixed on the conventional ballast. Therefore, the attachment of the grounding metal to the rail can be performed very easily and quickly, and the workability is good. In addition, since one end of the grounding metal is T-shaped, a substantially bowl-shaped rod having a certain length is brought into contact with the lower surface of the rail jaw, and the tapered other end is connected to the rail fastening device metal fitting. Since it is locked only by piercing in between, when these are stretched, the grounding metal fitting can be stably attached. Moreover, since the other end of the grounding metal is tapered in this way, it can be locked to many types of rail fastening devices. Further, it means for the Tsuppara is only turn the handle, or taut to reliably and easily, can retract, has the advantage work is easy. Furthermore, since the handle is provided on the side surface perpendicular to the direction of one end and the other end of the grounding metal, the handle can be attached upward in particular, and the mounting operation of the grounding metal becomes extremely easy.
