Description

Technical field

The device relates to the design of the upper structure of the railway track, in particular to the site of the intermediate rail fastening, providing the installation of the rail in a geometrically predetermined position when the rail head is worn.

State of the art

In the curved sections of the path of small radius with high load intensity, intense wear of the head of the running rail often occurs. As a result, the track gauge increases, affecting the safety of train traffic and, as a result, the safety of passengers and the safety of transported goods.

The restoration of the gauge is solved in different ways, for example, by replacing the rails. To extend the service of the rail and install it in a geometrically structurally predetermined position, elements are used in the form of inserts, for example metal plates of various thicknesses, to adjust the rail spacing.

In the prior art, rail fastening is known (see RU 2398923, class ЕВВ 9/44, published September 10, 2010) containing a rail liner made with transverse protrusions defining the rail section and, accordingly, the lateral displacements of the rail. The rail sole is pressed into the under-rail lining with a bolt-and-bolt mount. To adjust the gauge, a control element is used, mounted on one side of the sole of the rail. The above regulatory element is at least one flat plate with a cutout under the terminal to limit the possibility of displacement of the specified plate in the vertical and horizontal directions.

A disadvantage of the known design is the possibility of losing the regulatory element (plate) during installation of the intermediate rail fastening unit, since the regulatory element (plate) is not fixed relative to the rail lining.

The specified technical result is achieved in a device for intermediate rail fastening containing a rail liner, made as a single piece with two sub-terminal sections, between which there is a rail section limited by two transverse protrusions, a control element mating with one of the transverse protrusions of the rail liner, according to the utility model, the regulating element is equipped with two hooks covering sections of opposite sides of the sub-terminal section of the rail liner.

The peripheral sections of the hooks, covering the sections of opposite sides of the sub-terminal section of the rail track, can be placed in the recesses or grooves of these sides of the sub-terminal section.

The regulating element may be provided with two opposite boundary walls located above the hooks and preventing the displacement of the regulating element in the transverse direction of the rail liner.

Accordingly, the explanatory figures and the detailed description of the device for intermediate rail fastening are illustrative, but not restrictive.

The best option for implementing a utility model

A device for intermediate rail fastening (see figure 1) contains a rail lining 1 and a regulating element 2.

The under-rail lining 1 is made as a single integral part and contains two sub-terminal sections 1a between which the under-rail section 1b is made, limited by two opposite transverse protrusions 3 to limit lateral movements of the rail 6.

Each of the transverse protrusions 3 contains lower 3a and upper 3b sections, side cutouts forming free zones 4, in which there are sections of spring terminals 5, pressing the sole 6a of the rail 6 to the rail lining 1. The length L1 of the lower portion 3a of each of the transverse protrusions 3 corresponds the width N of the rail section 1b. The length L2 of the upper portion 3b is less than the length L1 of the lower portion 3a due to the above free zones 4 (see figures 2, 3).

The control element 2 is installed in the under-rail section 1b of the under-rail lining 1 and is coupled to one of the transverse protrusions 3.

The regulatory element 2 is made of a plate, in particular metal, and contains two bent opposite opposite hooks 7 and two opposite boundary walls 8 located above the hooks 7.

The above regulatory element 2 can be made of various thicknesses necessary to adjust the range of displacement of the rail 6 relative to the transverse protrusion 3 of the rail lining 1.

The hooks 7 are made in the lower part of the regulating element 2 and cover the sections of the opposite sidewalls 9 of the sub-terminal portion 1a located adjacent to the said regulating element 2, which prevents the spontaneous disconnection of the said regulating element 2 from the rail liner 1.

The above-mentioned peripheral sections 7a can be placed in the recesses 10 of the sidewalls 9 of the sub-terminal section 1a (see figures 1, 3, 4), which practically eliminates the possibility of spontaneous displacement of the regulating element 2 in the vertical and longitudinal directions of the rail liner 1.

It does not exclude the possibility of placing the peripheral sections 7a of the hooks 7 in the grooves (not shown in the figures) made in the sidewalls 9 of the sub-terminal portion 1a.

The hooks 7 can be made in terms of an arcuate shape (see figure 3), which increases their springy properties and, as a result, the reliability of fixation of the regulatory element 2.

The bounding walls 8 of the regulating element 2 are located on opposite sides of the upper portion 3b of the transverse protrusion 3, thereby preventing the displacement of the regulating element 2 in the transverse direction of the rail liner 1.

Rail lining 1 can be made of metal or a polymer composite material, polyamide with glass filling or mineral filling, or other high-strength material having similar or improved strength properties.

The under-rail liner 1 may be provided with a metal plate 11, one-piece connected from the outside of the under-rail section 1b with its base 1c and transverse protrusions 3, while said plate 11 is provided with local protrusions (not shown in the figures) embedded in the body of the under-rail liner 1.

The under-rail lining 1 contains holes 12 for mounting fastening devices 13, by means of which it (under-rail lining 1) is attached to the sleeper 14 (see figure 5). As fastening devices 13 can be used screw, bolt, anchor and other connections known from the prior art.

The under-rail lining 1 can be provided with two pairs of longitudinal protrusions 15 made in the sub-terminal sections 1a. The longitudinal protrusions 15 can be made rectilinear or J-shaped in plan, which facilitates the installation and positioning of the spring terminals 5 in the intermediate rail fastening.

The device operates as follows.

In the curved sections of the path of small radius, there is intense wear of the head 6b of the rail 6, which leads to an increase in the gauge. To restore the track gauge, rail 6 needs to be replaced. To extend the life of rail 6, the above-described device is used with a rail section 1b located asymmetrically relative to the longitudinal axis of rail 6. To set rail 6 in a geometrically specified position, control element 2 is initially used, which is equal in thickness to the relative the shift of one of the transverse protrusions 3 of the rail support 1. The specified control element 2 is initially installed on the inner side of the track, as shown in figure 5. When the head 6b of the rail 6 is worn to restore the necessary track gauge after preliminary loosening the pressure by the spring terminals 5 of the sole 6a of the rail 6, it is necessary to remove the adjusting element 2 and reposition it on the opposite transverse protrusion 3 of the rail liner 1 from the outside of the track, then move the sole 6a of the rail 6 to a new predetermined position and tighten the fastening devices 13.

The above-described device for intermediate rail fastening provides a constant connection of the regulating element 2 with the rail lining 1 during their transportation and installation of the intermediate rail fastening. This eliminates the loss of the regulatory element 2 or its incorrect location in the intermediate rail fastening.

The above construction increases the operational reliability of the intermediate rail fastening and ensures the stability of the position of the rail track during operation. Reliable intermediate rail fastening increases the safety of train traffic and, as a result, the safety of passengers and the safety of transported goods on curved sections of a small radius track.
