Description

The utility model relates to devices of the upper structure of a railway track, in particular to a railway track in curved sections, a railway track in level crossings and turnouts.

A device for preventing lateral wear of rails in curves, providing a uniform distribution of lateral forces between the inner and outer threads of the rail gauge (RU No. 21114946, EB 5/18, 07/10/1998), comprising a counter rail, rigidly connected to the rails of the inner gauge and using spacer connected to the neck of the rails of the outer thread of the gauge.

The disadvantage of this design is the inability to adjust the width of the trough between the working faces of the rail of the inner thread of the rail track and the counter rail, which, due to wear of the counter rail during operation, leads to an uneven distribution of the transverse load from the rolling stock between the counter rail and the outer rail thread, as a result of which the stability of the rail track and reduced road safety in curves.

Another significant drawback of the device is the low structural strength at lateral loads, due to the small supporting surface of the pedestals, rigidly fixed to the inner ends of the rail linings on which the counter rails are mounted.

Also a significant drawback of this design is the lack of the ability to install, repair and replace, failed during operation, structural elements without dismantling the track rail.

The known design of the device to prevent the descent of the railway vehicle on a curved section of the railway track of small radius and lateral wear of the rails (RU No. 150332 U1, ЕВВ 5/18, 02/10/2015), containing a rail, a counter rail, mounted on the side of the rail and mounted vertically through the neck on a support stand with stiffening ribs of the counter-rail lining by means of a detachable connection, which is installed and mounted on the railroad bed under the rail and the rail lining, as well as the device fastening means, excellent yuscheesya in that the counter rail is used as kontrrelsovy area, and rail kontrrelsovaya lining not mated with each other and are formed separately, with only a general fastening means for railway sleepers.

The disadvantage of this device is the reduced stability of the path due to the redistribution during operation of the loads from the wheels of the rolling stock mainly on the outer rail thread, caused by a change in the width of the trough between the rail of the inner rail thread and the counter rail due to the displacement of the counter rail lining inside the track under the influence of lateral forces transmitted from the wheels of the rolling of the composition on the counter rail due to the fact that the rail and counter rail linings are not joined together and are made separately, having only a common means of fixing to the sleepers.

Another disadvantage of this design is the reduced stability of the track due to a change in the height position of the inner rail thread relative to the outer rail thread due to the location of the counter rail lining under the rail and the rail lining, which leads to a redistribution of loads from the wheels of the rolling stock, so that the loading of the outer rail thread increases .

Also, a significant drawback of this design is the lack of the ability to install, repair, and replace structural elements that have failed during operation without dismantling the track rail.

A device is known for ensuring traffic safety and reducing lateral wear of rails in curves (RU No. 165319 U1, 04/06/2016), comprising a counter rail and a single supporting surface — a support plate with flanges for fastening the rail of the inner thread of the rail track and a stop for securing the counter rail, which is connected with a base plate by means of persistent kerchiefs, the counter rail being connected to the stop through a washer, characterized in that it further comprises an insulating gasket under the base plate, as well as insulating sleeves located in the hole The height of the base plate between the base plate and the attachment points, which in their design contain a embedded part. This design is taken as a prototype.

The disadvantage of this design is the reduced structural strength at lateral loads, due to the small contact surface of the base plate and the stop for securing the counter rail.

Also a significant drawback of this design is the lack of the ability to install, repair and replace, failed during operation, structural elements without dismantling the track rail.

The tasks to be solved by the claimed utility model are:

1. improving traffic safety by increasing the stability of the track by ensuring a constant size of the trough between the track rail and the counter rail with the complete exclusion of the influence of the device on the height position and slope of the track rail and, as a result, on the distribution of loads arising in the rail threads when passing the wheels of the rolling stock ;

2. ensuring the possibility of installation, repair and replacement of structural elements that fail during operation, structural elements without dismantling other track structures.

The technical result is to increase the stability of the path, which leads to increased traffic safety.

The technical result is achieved in that the device for ensuring traffic safety and reducing lateral wear of the rails, comprising a counter rail and stops for fastening the counter rail, the counter rail being connected to the stops through washers, according to the claimed solution, the stops have joint assemblies with intermediate rail fasteners to the rail base, moreover stops have a common plane of contact with the sole of the track rail and are connected directly to the track rail.

The connection of the stops with the track rail eliminates the possibility of displacement of the stops under the influence of the load from the wheels of the rolling stock, which ensures the constancy of the size of the counter track, as a result of which the track stability is increased, side wear of the track rails is reduced, which leads to increased traffic safety.

The design of the device eliminates its effect on the altitude and the slope of the track rail, as a result, the specified path parameters are provided, which leads to increased traffic safety.

The common plane of contact with the sole of the track rail completely eliminates the possibility of tipping the device under the influence of horizontal forces transmitted from the wheels of the rolling stock.

Counter rail 1 can be attached to stops 2 using detachable connections: bolts 3, washers 4, nuts 5. Counter rail 1 can be attached to stops 2 using other types of detachable connections (not shown in the drawing). Washers 6 are installed between the counter-rail 1 and the stops 2, which make it possible to adjust the gap between the side face of the track rail 7 and the working surface of the counter-rail 1. As a counter-rail 1, a counter-rail corner, for example, SP-850, can be used. As the counter rail 1 can be used counter rail (not shown). As a counter rail 1, other types of rails can be used (not shown in the drawing). The stops 2 and the intermediate rail fasteners 8 are attached to the rail base 9 using common fastening nodes. Detachable connections can be used as general attachment points: embedded bolts 10, nuts 11, washers 12. Other types of detachable connections can be used as general attachment points (not shown in the drawing). The stops 2 have a common plane of contact with the sole of the track rail 7. The stops 2 are connected directly to the track rail 7. The stops 2 can be connected to the track rail 7 in a groove. The stops 2 can be connected to the track rail 7 using detachable connections: bolts 13, pressure plates 14, washers 15, nuts 16. The stops 2 can be connected to the track rail 7 using other types of detachable connections (not shown in the drawing).

A device to ensure traffic safety and reduce lateral wear of the rails works as follows: when the driveway moves in curved sections of the track under the action of centrifugal forces, and when moving in straight sections under the influence of rolling stock wobble, the wheel pairs against the inner surface of the wheel abut against the working surface of the counter rail, due to which there is a decrease in the lateral load transmitted from the wheels of the rolling stock to the track rails. The connection of the stops with the track rail completely eliminates the possibility of displacement of the device during operation, and, therefore, ensures the constancy of the size of the trough between the track rail and the counter rail, which in turn increases the stability of the rail track and leads to increased traffic safety. The attachment of the device to the rail base using the fastening nodes common with intermediate rail fastenings ensures constant construction position during operation, which increases the stability of the rail track, and also allows the device to be insulated from the rail base. The common plane of contact with the sole of the track rail completely eliminates the possibility of tipping the device under the influence of horizontal forces transmitted from the wheels of the rolling stock. The device is designed in such a way that it completely eliminates the influence of the device on the height position and slope of the track rail, as a result of which the operational parameters set by the original track design are ensured, which eliminates the eccentricity of the transmission of vertical force from the conical wheels of the rolling stock to the track rails and contributes to an increase in resistance to their horizontal lateral forces , which increases the stability of the rail track, and, consequently, improves traffic safety.
