本案は第３図に示すように、２組の軌条Ａ、Ｂが交叉す
る軌条分岐部において偶発的に発生する両軌条間の電気
的短絡を防止する絶縁装置に係るものである。[Detailed description of the invention] As shown in Fig. 3, this invention relates to an insulating device that prevents an electrical short circuit between two sets of rails A and B that occurs accidentally at a rail branch where they intersect. It is something.

る。In the track branching section, an insulating gap provided near the center O of the four rail pieces branching out in an X-shape around the center O of the rail crossing, or an insulating member interposed in the gap. A joint plate connects the opposite ends of the rail pieces that sandwich the rails, but since the area around the joint plate is subject to large fluctuations in load due to train running, a tie-brake is installed under each rail) 3 .3' is laid and fastened to sleeper C,
This is aimed at dispersing the load that is locally concentrated on sleepers C.

。However, each tie brake 1-3 of both rails A and B.
3' are very close near the intersection point, so if the rail fastening fittings bolts, nuts, washers, etc. fall off for some reason, the two rails will contact and short-circuit through them, causing an abnormal signal current. It had the disadvantage of flowing.

条分岐部における絶縁装置に係るものである。The present invention was proposed to eliminate such drawbacks, and the insulating member a made of an electrically insulating material, in which the vertical barrier piece 2 is suspended from the horizontal mounting piece 1, is opposed to each other at the rail branch part. A rail characterized in that it is arranged between a pair of tie plates 3 and 3' interposed between the rails A and B and the sleeper C, respectively, and the horizontal mounting piece 1 is fixed to the sleeper C. This relates to an insulating device at a branch section.

こともできるようになっている。The insulating member a is made of, for example, rubber, and the horizontal mounting piece 1 and the vertical barrier piece 2 are each provided with through holes 4 for mounting nails to the sleeper C.
It is also possible to use the horizontal mounting piece 1 as a vertical barrier piece.

The screw spikes 8 and 9 to be fixed are metal fittings for fastening the track, bolt/nut washers, etc.

触が防止されるものである。In this case, as described above, insulating members a each having a vertical barrier piece 2 hanging from a horizontal mounting piece 1 are interposed between opposing rails A, B and sleepers C at the rail branching part. Since the horizontal mounting piece 1 is fixed to the sleeper C, for example, when using a bolt release device, the screw spike on one rail A or B side and the rail If the fastening bolt or washer falls off, the presence of the vertical barrier piece 2 of the insulating member a prevents these from coming into contact with the other rail B or A and its fastening member.

信号電流の発生を防止しうるものである。(Figure 1) According to the present invention, with a simple configuration, it is possible to reliably prevent electrical short circuits that occur accidentally between side rail sections that face each other in close proximity at a rail branch, and to prevent abnormal signal currents. This can be prevented from occurring.
