Description

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

A well-known design of a railway turnout (RU No. 110381, E01 B7/00, 2011), containing the main path and a side path with a working edge of the transfer curve, docked at one end with the sharp point of the switch, the other with the front overhang of the cross. Such a switch with a straight main direction is intended for laying only in a straight line. When laying it in a curve, you have to straighten a part of the curve along a tangent or secant. Such a change in the track scheme is not always possible, because. on industrial railways in conditions of dense development, it requires changes in the position of construction objects of the general plan, which is associated with significant capital costs.

The closest to the proposed technical solution is the design of a railroad turnout (RU No. 210219, Е01В 7/00, 04/01/2022), containing the main path and the side path with the working edge of the transfer curve, docked at one end with the sharp switch, the other with front departure of the cross. The radius of the curve Rk, in which the turnout of brand 1/3 is laid, is 550 m and is equal to the radii of curvature of the working edges of the wit, the turnout curve and the cross of the main direction, and the radius of the side branch Rb is 18.3 m.

The disadvantage of the design is that turnouts of grade 1/3 and the most flat ones are not used on the factory tracks, since track schemes consisting of transfers of flat grades do not meet the requirements of compactness of track developments of master plans.

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

The technical result is the expansion of the area of use of the railroad turnout by reducing its length.

The technical result is achieved by the fact that in a railway turnout containing the main track and a side track with a working edge of the transfer curve, docked at one end with the point of the switch, the other with the front outreach of the cross, the radius of the curve into which the turnout of the mark 1/2 is laid, 5 is 400 m and is equal to the radius of curvature of the working edges of the wit, the transfer curve and the cross of the main track, and the radius of the side track is 15.4 m.

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

The railroad turnout contains a main track 1 and a side track 2 with a working edge 3 of a transfer curve 4, joined at one end 5 with a sharp switch 6, the other 7 with a front departure 8 of a cross 9. The radius of the curve 4 Rk, in which the turnout of brand 1 is laid /2.5, is 400 m and is equal to the radii of curvature of the working edges of the sharp arrow 6, the transfer curve 4 and the cross 9 of the main track 1, and the radius of the side track 2 Rb is 15.4 m. The values of the radii of the curve and the side track are determined by calculation.

For intra-factory tracks, the permissible train speeds, established based on the operational requirements of the enterprises, are not higher than 40 km / h, which guarantees the possibility of free passage of factory locomotives and wagons along any branch of the proposed railroad switch.

The device works as follows.

The transfer is laid in curve 4 with a radius Rk equal to 400 m. The radius Rb of the side track 2 is 15.4 m, which ensures the passage of technological cars at speeds up to 25 km/h, set for the movement of trains along the intra-plant tracks.

Thus, a railroad turnout placed in a curve with a radius Rk equal to 400 m meets the requirements of compact track layouts, which allows it to be used on densely built-up sections of factory tracks.
