Abstract

FIELD: construction.

SUBSTANCE: adjustable insert rail fastening, adjusting the pressure of the rail clip to the rail foot situated on the reinforced concrete tie bars, consists of a tie plate having shaped holes aligned with the bores in the tie, and of a base plate which has flanges and bores aligned with the holes in the tie and on which the rail clip sits. One of its sections is located on the rail foot and the other one is placed under the eccentric above the cylindrical ends of which there are curved parts of paired U-shaped bolts introduced into the base plate, tie and tie plate holes. The nuts with adapters are screwed on the ends of the bolts and, when the eccentric pivots and the rail clip is pressed to the base plate and the rail foot, they shift upwards. The nut adapters nuts are recessed in the shaped holes of the tie plate and their wide part thrusts against the tie plate locking the basic elements of the rail fastening in this position, but keeping the possibility of increasing the pressure on the rail clip by rotating the eccentric.

EFFECT: stable gauge and reliable operation of the rail fastening elements in the range exceeding the established turnaround cycle.

Description

The invention is a device that is not attenuated by vibration of an adjustable embedded rail fastening located on a reinforced concrete sleepers, providing a stable gauge and trouble-free operation of rail fastening elements within the limits exceeding the established overhaul cycle.

For high-speed railways, the ARS type rail fastening is currently used [1, 2], where the anchor serves as the spring clamp holder for the rail fastening. The disadvantages of this design of the rail fastening terminal holder include both the significant weight of the anchor and the method of connecting the terminal holder to the rail, which causes a number of technological difficulties in both manufacturing and operation. For example, part of the anchor is destroyed without the possibility of its restoration, and the entire sleepers become unusable.

At the same time, the existing embedded options for rail fastenings (design bureau, reinforced concrete, power supply, and reinforced concrete) are weakened by vibration, which jeopardizes the failure-free operation of the rail fasteners.

Adjustable embedded rail fastening, regulating the pressing of the spring clamp to the rail heel, located on the reinforced concrete sleepers, consisting of the under-sleeper lining having profile holes coaxial with the holes in the sleepers, as well as a gimbal with flanges and holes, coaxial holes in the sleepers, on which the spring fits , while one of its sections is located on the heel of the rail, and the other is placed under an eccentric, over the cylindrical ends of which are rounded sections of paired U-shaped studs, the holes in the mount, the sleeper and the under-sleeper lining, on the ends of which nuts with adapters are screwed, which, after turning the eccentric around the axis and pressing the spring clamp to the mount and the rail heel, are displaced upward, while the nut adapters are recessed in the profile holes of the sleeper lining, and its wide part abut against it, fixing this position of the main elements of the rail fastening, but leaving the possibility of increasing the pressure on the spring terminal by rotating the eccentric.

This technical solution will significantly reduce the total weight of the rail fastener, and will also allow it to be replaced if the spring clip of the rail fastener or U-pin is damaged without changing the sleepers. In addition, to simplify the technology of manufacturing reinforced concrete sleepers for the use of rail fastening of this type, which will reduce the cost of its manufacture.

This design of an adjustable embedded rail fastening is shown in the drawing. Operating position of adjustable embedded rail fastening.

This rail fastening consists of the following elements:

1 - sleepers;

2 - under-sleeper lining;

3 - U-shaped pair of hairpins;

4 - a fixing nut with an adapter;

5 - a subklemnik with flanges;

6 - spring terminal;

7 - an eccentric;

8 - rail;

9 - shock-absorbing lining.

In the operating position shown in the drawing, the gimbal with flanges (5) is pressed tightly against the railroad tie (1) by a spring terminal (6), which is under pressure from the eccentric (7), which abuts with its cylindrical ends in the rounded part of the U-shaped pair of studs (3) and held in this position by fixing nuts with adapters (4) screwed onto the ends of U-shaped pair of embedded studs (3), which are in the transitional sections of the profile holes of the sleeper lining (2) and sleepers (1), and abut against the surface with a wide part basement lining ki (2). In this case, the regulatory action of the central part of the eccentric (7) remains, since it abuts with its cylindrical ends in the rounded part of the U-shaped pair of embedded studs, it is able, by rotating, to increase the pressure on the spring terminal (6) to increase its pressure on the rail heel (8), resting on the sleeper (1) through the lining (9), and the nuts (4) fixed in the profile holes of the under-sleeper lining (2) and the sleepers (1) cannot loosen spontaneously under the influence of vibration.

This version of the adjustable embedded rail fastening is inexpensive to manufacture, convenient to operate, easy to mount on the sleeper and dismantled, and, therefore, can be replaced element by element and restored if damaged without replacing the sleeper.

The claimed technical solution with these features is currently not known in the Russian Federation and abroad and meets the requirements of the category of "novelty."

The claimed technical solution is original, provides an unconventional approach to solving problems and does not follow obviously from the existing level of technology, and also meets the requirement of the criterion of "inventive step".

The claimed technical solution can be implemented industrially using known technical means, technologies, materials and meets the requirement of the criterion of "industrial applicability".
