Description

The utility model relates to the field of transport construction, namely to such devices of the upper structure of a railway track as turnouts.

A railway turnout design is known (RU No. 110381, E01B 7/00, 2011) comprising a main track and a side track with a working edge of a turning curve, joined at one end to the point of the turnout, and at the other - to the front extension of the frog. Such a turnout with a rectilinear main direction is intended for laying only in a straight track. When laying it in a curve, it is necessary to straighten part of the curve along a tangent or secant. Such a change in the track layout is far from always possible, since on industrial railways in conditions of dense development it requires changes in the position of construction objects of the general plan, associated with significant capital costs.

The closest to the proposed technical solution is the design of a railway turnout switch (RU No. 226352, E01B 7/00, 31.05.2024), containing the main track and a side track with a working edge of the switching curve, connected at one end to the switch point, and the other - to the front extension of the frog. The radius of the curve R _k , in which the turnout of brand 1/2 is laid, is 550 m and is equal to the radii of curvature of the working edges of the switch point, the switching curve and the frog of the main direction, and the radius of the side branch R _b is 13.1 m.

The design flaw is that turnouts of grade 1/2 and the most flat ones are not used on the factory tracks of open-hearth shops, since track layouts consisting of turnouts of flat grades do not meet the requirements for the compactness of track developments of general plans.

When working on the utility model, the problem of creating a railway switch, laid in curves, for use on densely built-up sections of factory tracks of open-hearth shops was solved.

The technical result is the creation of a railway switch, laid in curves, for use on densely built-up sections of factory tracks of open-hearth shops.

The technical result is achieved in that in a railway switch comprising a main track and a siding with a working edge of a switching curve, joined at one end to the switch point and at the other to the front extension of the frog, the radius of the curve in which the 1/1.5 brand switch is laid is 500 m and is equal to the radius of curvature of the working edges of the switch point, switching curve and frog of the main track, and the radius of the siding is 10.4 m.

The essence of the technical solution is explained with the help of a drawing, which shows a diagram of a railway switch.

A railway turnout comprises a main track 1 and a siding 2 with a working edge 3 of a turning curve 4, connected at one end 5 to a switch point 6, and at the other 7 to a front extension 8 of a frog 9. The radius of the curve 4 R _k , in which a turnout of brand 1/1.5 is laid, is 500 m and is equal to the radii of curvature of the working edges of the switch point 6, the turning curve 4 and the frog 9 of the main track 1, and the radius of the siding 2 R _б is 10.4 m. The values of the radii of the curve and the siding are determined by calculation.

For the internal plant tracks of open-hearth shops, the permissible train speeds, established based on the operational requirements of the enterprises, are no higher than 40 km/h, which guarantees the possibility of free passage of plant locomotives and wagons along any branch of the proposed switch.

The device operates as follows. The switch is laid in curve 4 with radius R _k equal to 500 m. Radius R _b of side track 2 is 10.4 m, which ensures the passage of process cars at speeds of up to 25 km/h, established for the movement of trains along the internal plant tracks of open-hearth shops.

Thus, a railway switch placed in a curve with a radius R _k equal to 500 m meets the requirements for compact track layouts, which allows it to be used on densely built-up sections of factory tracks in open-hearth shops.
