Rail butt electrical insulating joint

The utility model relates to the upper structure of the railway track and can be used in the construction of rail butt electrically insulating adhesive bolt joints with various types of overlays.

A rail butt electrical insulating joint is known, comprising metal plates with recesses located on both sides of the rails by means of fasteners with recesses on the side of the rails and an electrically insulating material between rails and metal plates with recesses (see A. S. USSR No. 1799939, KL.E01V 11 / 54).

The presence of metal pads indentations reduces the strength of this rail butt electrical insulating connection.

Another rail butt electrical insulating joint is known, comprising metal plates located on both sides of the rails by means of fasteners with inserts in their recesses on the side of the rails and electrical insulation material between the rails and metal plates with inserts (see patent of the Russian Federation No. 2181154, class E01B 11/54).

This rail butt electrical insulating joint is stronger than the one described above, since it has inserts in the recesses of the metal plates.

However, the strength of this rail

electrically insulating compound is not high enough, as it depends only on the fasteners. The present utility model is based on the development task

rail butt electrically insulating joints, increasing its strength.

The delivery problem is solved in that the rail butt electrically insulating joint, comprising metal plates located on both sides of the rails by means of fasteners with inserts in their recesses on the side of the rails and the electrically insulating material between the rails and metal plates with inserts, has adhesive layers fastening the electrically insulating material with rails.

The difference of the proposed rail

an electrically insulating compound from the above known, closest to it, is that it has adhesive layers holding the electrically insulating material with rails.

Thus, the technical result of the proposed rail butt electrically insulating joints is to increase its strength.

The proposed rail butt electrical insulating connection is illustrated by the drawings shown in figures 1 and 2.

Figure 1 shows a rail butt electrical insulating connection with two-headed plates;

figure 2 - rail butt electrically insulating connection with enclosing overlays.

The rail butt electrical insulating joint comprises metal plates 2, which are tightened by means of fasteners on both sides of the rails 1, with liners 3 in their recesses on the side of the rails 1 and electrical insulation material 4 between the rails 1 and the metal plates 2 with liners 3.

2 Fasteners are made in this particular example in

in the form of bolts 6, nuts 7 and washers 8.

As the adhesive layers 5 can be used: fiberglass T 13 (GOST 19170-73), modified epoxy resin K-153-100 (TU2225-509-00203521-94), polyethylene polyamine PEPA (TU602-594-85); fiberglass 33-200P (TU 5952-034-0020-4961-97), epoxy-diane resin uncured ED-20-100 (GOST 10587-93), low molecular weight polyamide resin L-19-60-80 (TU6-05-11230 -74).

During operation of this rail butt electrically insulating joint, the displacement of the electrically insulating material 4 relative to the rail 1 is excluded.

Such a constructive implementation of the proposed rail butt electrical insulating joints can increase its strength.

Claims (1)

A rail butt electrical insulating joint, comprising metal plates arranged on both sides of the rails by means of fasteners with inserts in their recesses on the side of the rails and electrical insulation material between the rails and metal plates with inserts, characterized in that it has adhesive layers fastening the electrical insulation material with rails.
