BACKGROUND OF THE INVENTION

A construction of a conventional detachable rail joint is known, consisting of a railway rail attached to a wooden beam by means of seals attached to a fixing plate and an elastic pad, the front end of the seals being provided with a trapezoidal groove for fixing The seals are fixed by means of T-bolts located outside the compression zone of the side surface of the rail, which allows a stable fixation to the wooden beam and easy assembly and disassembly.

Known construction of rail fastening / type KS 24 of Vossloh Fastening System GmbH /, consisting of a railway rail attached to a wooden traverse by means of a cast iron ribbed pad and an elastic pad, in which the rail is fixed to the wooden traverse by a system of double-sided fasteners bolts, two washers, two nuts, four earplugs and two elastic clamps, the earplugs are wound into the wooden traverse through holes formed in the cast iron pad.

Technical essence of the utility model

The purpose of the utility model is to create an optimized construction of an elastic underlying rail fastening for wooden sleepers with high indicators of reliability, durability and efficiency of the structure.

The essence of the utility model is to create a rail fastening for wooden sleepers, consisting of a railway rail attached to a wooden sleeve by means of a cast iron ribbed pad and an elastic pad 45 by a set of fasteners consisting of elastic brackets, pins and dowels. The cast iron ribbed pad is fixed to the wooden beam by means of countering cones located in the conical part of the fixing

2112 UI

- the construction is high-tech and economical as execution, installation, maintenance and operation, with a high degree of reliability and good operational characteristics, due to the significantly reduced number of fasteners (from 3 8 to 18) and its placement in the form of a blank ready for installation at the place of construction and repair of the railway.

Explanation of the attached figures

An exemplary embodiment of a rail fastening structure, subject to the utility model, is shown in the following figures:

figure 1 - cross section of the fastening;

Figure 2 is a side view of the ribbed pad;

Figure 3 - top view of the ribbed pad.

Example of implementation of the utility model

This example illustrates the utility model without limiting it.

Rail fastening for wooden sleepers / fig. 1 /, consisting of a railway rail 1 attached to a wooden beam 2 by means of a cast iron rib under a spoon 3 and an elastic pad 4 by a set of fasteners consisting of elastic brackets 5, pins 6 and dowels 7. The wooden beam 2 is provided with fixing holes 8, conical in their upper part, located symmetrically with respect to the axis. 9. The cast iron rib pad 3 / fig. 2 and FIG. 3 / is provided with countering cones 10 located on its lower surface, symmetrically with the fixing ribs 11 from its upper surface and through holes 12 cut in the ribs 11 and the countering cones 10. The cast iron rib pad 3 is fixed to the wooden beam 2 by means of counter bars. cones 10 located in the conical part of the fixing holes 8 of the wooden traverse 2 and the pins 6 passing through the through holes 12 of the cast iron ribbed pad 3 and fixed in the dowels 7 wound in the lower part of the fixing holes 8. The rail 1 is attached to the wooden traverse 2 by means of a cast iron ribbed pad 3 and an elastic pad 4, laterally by the fixing ribs 11, vertically by the elastic brackets 5, pressed by the ottomans 6 fixed in the dowels 7, wound in the fixing holes 8 of the traverse 2.

Using the utility model

The construction of rail fastening for wooden sleepers, subject of the utility model, is used in the construction of new and repair of existing railways, as its implementation is carried out by pre-construction of the fastening in workshop conditions, using a special device in the traverse 2 drill fixing holes 8 with variable cross section along its height, parallel to the axis 9, as in its upper part the fixing hole 8 is conical with a trapezoidal cross section, and in the rest it has a rectangular cross section. Then in the lower part of the fixing hole 8 with the rectangular cross section a dowel 7 is wound. On the traverse 2 two cast iron ribbed pads 3 are placed, provided with countering cones 10 located on their lower surface and fixing ribs 11 located on their upper surface. , so that the countering cones 10 fall into the conical part of the fixing holes 8 of the wooden beam 2. Then through the through holes 12 of the cast iron ribs under spoons pass tirfoniteb, mounted to elastic brackets 5 are wound into the dowels 7 so that the elastic brackets 5 located outside the area of the fixing ribs 11 of the cast iron rib pads 3, which completes the process of building the fastening blank in production conditions. The blanks are transported to the place of construction or repair of the rail track, placed under the rails 1 so that their heels fall in the area between the fixing ribs 11 of the cast iron ribbed pads 3. The tyrphones 6 develop slightly, the elastic brackets 5 move forward in the heel area of the rails 1, after which the rails 1 are pressed laterally by the fixing ribs 11 and vertically by the elastic clamps 5, by winding the trumpets 6 to the end position.
