Abstract

FIELD: construction.

SUBSTANCE: method of a rail road operation includes movement of vehicles on it. The rail road comprises two guiding track rails formed by rails coupled with a gap. End joints of rails adjacent to one gap are made at different angles to a horizontal plane.

EFFECT: increased safety of movement along a rail road, reduced power inputs for damage of rails and mobile units of railway transport, reduced rail crepage, lower impact loads and noise that affect people and environment, increased service life of a rail road and rolling stock.

Description

The invention relates to a railway device and can be used in the construction and repair of railway and tram tracks, underground.

A well-known railway containing two guide rail threads formed by rails docked with a gap (USSR AS No. 998624, ЕВВ 2/00, publ. 23.02.83, bull. No. 7).

Its disadvantage is the rapid wear of the rails and wheels of a passing vehicle, associated with large shock loads experienced by the butt ends of the rails and the wheels of the vehicles during the passage of rail joints.

The specified railway is the closest analogue of the invention.

The technical result of the invention is to increase railway safety, reduce energy costs for the destruction of rails and mobile units of railway transport, reduce theft of rails, reduce shock loads and noise affecting people and the environment, increase the convenience and comfort of passengers, increase the life of the railway roads and rolling stock.

The technical result is achieved due to the fact that on a railroad containing two guide rail threads formed by rails docked with a gap, the butt ends of rails adjacent to one gap are made at different angles to the horizontal plane.

Under the railway also understand its separate section (segment), limited in length, and under the vehicle - a unit of rolling or traction rail.

Obviously, when passing vehicles with a minimum weight by rail, the rail bend at the junction will be the smallest, and when passing vehicles with a maximum weight by rail, the rail bend at the junction will be the greatest.

Figure 1 conventionally shows the rail joint of the railway, taken as a prototype, side view, figure 2 - rail joint of the proposed railway, side view.

The dashed lines show the initial state of the butt ends of the rails before passing along the rail joint of the vehicle wheel.

The known rail joint (Fig. 1) contains rails, the butt ends of which 1 and 2, when the vehicle wheel 3 passes through the gap 4, bend (bend) like consoles, with the formation of “dead zones” AB and CD, through which the wheel “jumps” 3 followed by a strike on the butt end of the receiving rail. Therefore, the flattening of the ends of the rails usually has the greatest width not at the end, but at a certain distance from it; almost at each end of the rail there is even an “influx” towards the gap. Obviously, the larger the deflection of the butt ends 1 and 2 of the rails, the greater the distance between points A and D, which are the points of contact of the wheel 3 and the rolling surface of the butt ends 1 and 2 of the rails, the stronger the impact of the wheel 3 on the butt end of the receiving rail.

The butt ends 5 and 6 of the rail junction of the railway (figure 2) in the initial state are made with the rise towards the junction (gap) at an angle α.

The railway is operated as follows.

By rail, the movement of vehicles (rolling stock and traction). When the wheel 3 of the vehicle passes along the butt ends 5 and 6, each of which is lifted towards the gap 7 at an angle α to the horizontal plane, the butt ends 5 and 6 under the influence of the vertical loads created by the wheel 3 bend, which leads to a decrease or disappearance "Dead zones" (AB and CD in figure 1), which reduces the impact force of the wheel 3 on the receiving rail.

To ensure the angle α, elements are installed under the butt ends of the rails 5 and 6, which are made in the form of objects with a section in the vertical plane parallel to the railway axis in the form of a trapezoid, the larger base of which is directed towards the gap. These elements can be attached to the sleepers.

The method of operation of the railway, including the movement of vehicles on it, is that the movement of vehicles is carried out on the above railway.

This technical solution takes into account the fact that until the wheel of the vehicle touches the rolling surface of the receiving rail due to the difference in the elastic properties of the rail and the overlays, the bending angle of the butt end of the receiving rail is less than the bending angle of the butt end of the giving rail.

The method of operation of the railway, including the movement of vehicles on it, is that the movement of vehicles is carried out on the specified railway.

The proposed technical solutions can also be applied in the construction and repair of the jointless path, they are industrially applicable, have novelty, are not explicit for the average specialist.
