Description

The invention relates to transport construction and is intended for laying at intersections of roads and railways.

A railroad crossing is known, comprising railway rails, a number of sleepers perpendicular to the rails, a sleepers base, and also a deck consisting of slabs, in addition, a gutter space is formed between the rail’s inner surface and the slab into which the sealing strip is placed .

A disadvantage of the known device is the high complexity when carrying out work on replacing worn rails, which arises when it is necessary to remove a leveling deck, in addition, the production of sleepers of high material consumption is required.

A railway crossing is known, containing rails, railway sleepers, and flooring made of reinforced concrete slabs laid on a gravel base and wooden beds.

However, the known device has a complex and insufficiently reliable design, in addition, it is impossible to replace worn rails without dismantling the flooring.

The closest in technical essence and the achieved positive effect to the claimed invention is a device comprising a rail laid on sleepers, and a reinforced concrete coating for passage of non-rail vehicles made of separate plates located outside and inside the rail, while the plates are made with openings in the lower part for the corresponding sleepers, and the crossing is equipped with an additional layer of ballast placed under the base, the plates are supported on an additional layer of ballast, and the sleepers on new.

The disadvantage of this design is that the plates (blocks) are not mutually fixed, which allows them to move in the longitudinal and transverse directions. This leads to insufficient stability of the flooring and does not ensure the safety of trains, as on the inside of the rails, it is necessary to provide a gutter with fixed dimensions for the passage of the wheel flange, which cannot be carried out with this design.

In addition, serious difficulties will arise when installing this design. First, it is necessary to lay the ballast layer for the operating unit, smoothly level it and evenly (which is problematic) to seal. Then, dosed, only under the sleepers, lay another layer of ballast, compact it, lay the sleepers, attach

to them rails and install blocks.

Even if this is done, during operation, misalignment of the blocks and their uneven precipitation with respect to each other are inevitable, especially

touches the end blocks.

This design does not allow repair work on the track without completely disassembling the flooring.

The presence of a large number of small

5 blocks will increase the total closing time of the crossing for the movement of vehicles during the repair of the flooring during its service, as in this case, the probability of failure of individual

0 blocks (in comparison with a flooring consisting of a small number of large-sized elements), which will lead to the closure of the level crossing even if it is necessary to replace one block.

5 The aim of the invention is to increase the reliability of relocation, reduce the cost of its construction, repair and operation. The goal is achieved by the fact that the railway crossing contains a rail track,

0 laid on the cross members (which have expanding ends with inclined lateral surfaces and an elevated platform for supporting the rails), as well as a floor for the passage of a non-rail transport. The flooring plates have openings in the lower part of the interface with the upper surface of the beams, at the base of which there are hollows (openings) with surfaces inclined in the horizontal and vertical planes in

0 in the form of wedges with which the beams rest on the ends of the cross members to form wedge engagement. In addition, the openings in the lower part of the slabs are made closed along the perimeter, and the beams in the upper part contain end ledges. The openings between the plates and the rail contain elastic beams on rigid L-cut profiles x attached to the plates in the space between the cross members.

0 Comparative analysis in the prototype allows us to conclude that the declared railway crossing is characterized in that the slabs have openings associated with the beams, and openings are made in the base of the beams

5 in the form of wedges with which the beams rest on the cross members. Thus, the claimed technical solution meets the criterion of novelty.

Analysis of known technical solutions (analogues) in the field of transport

construction allows us to conclude that there are no signs in them that are similar to significant distinguishing features in the declared railway crossing, and to recognize significant differences as the corresponding decision in accordance with the criterion.

A railway crossing includes a rail track 1, which is laid on the cross members 2, a deck 3 for passage of non-rail vehicles, consisting of plates 4 located outside the rail track 1 and the plates 5 inside the rail 1.

Plates 4 and 5 are supported on beams b and 7. It is characteristic that the contact area is the upper surface of the beams 6 and 7 and the end ledges on them, as well as the surface of the openings formed from below on the plates 4 and 5 and corresponding to the width and the length of the beams 6 and 7 (Fig.2-6). In addition, the mutual fastening of the plates 4 and 5 with the beams 6 and 7 is carried out by means of vertical connections, for example, embedded bolts, screws, etc. (not shown in Fig.).

Plates 4 and 5 and beams 6 and 7 are made of durable material, for example reinforced concrete, which allows for the perception of external loads without the appearance of damage and unacceptable deformations. The base of the beams 6 adjacent to the track 1 has depressions 8 (Fig. 7) with surfaces inclined in the horizontal 9 and 10 vertical planes in the form of wedges with which the beams 6 are rigidly supported on the ends of the cross member 2 (Fig. 10 and 12). In this way, wedge engagement of the beams 6 and the cross members 2 is obtained.

A rigid connection into a single design of the plate 5 and two beams 6 located between the rail 1 on the cross members 2, eliminates their displacement along and across the rail 1. This increases the operational reliability of the railway crossing itself.

In addition, resting the beams b directly on the cross-members 2 provides a stable position of the plates 4 and 5 at the required level relative to the surface of the rolling stock of the rail 1 during operation of the railway crossing. The beams 7 are laid on a base (for example, a ballast layer), compacted to an extent that ensures equal precipitation of the cross members 2 from the effects of train and automobile loads, as well as a plumb part of the plate 4. This ensures that the plate 4 is at the required level relative to the rolling surface of the winding path 1 ( 1). To the lateral surfaces of the plates 4 and 5, edged with the channel 11 from the side of the rail 1, interspersed spans (Fig. 13) are attached elements of the L-shaped section 12, on which along the entire length of the plates 4 and 5 stacked and reinforced other rails 13, abutting outside the track 1 to the side face of the rail head (FIG. 5), and inside the track 1 to the neck of the rail (FIG. 6), and in the latter case, a groove is formed for passage of the wheel flange of the railway rolling stock (FIG. .12). When replacing worn rails, they are dismantled without removing the flooring as follows. First, elastic bars 13 are removed outside and inside the rail 1, then the rails of the rail 1 are freed from the fastening nodes 14, access to which is unobstructed, rises and leaves outside the railway crossing. Next, a new rail is installed in reverse order.

The proposed railway crossing allowed to save costs for its maintenance, the convenience of which is significantly increased, and the complexity is reduced. In addition, due to the reliable mutual fixation of the cross-beams, beams and plates, their displacement in the longitudinal and transverse directions is excluded, as well as equal settlement of the structure from external loads (train, car) is ensured. The latter makes it possible quite simply to maintain at the required level the position of the flooring plates relative to the rolling surface of the rails. Thus, increased operational reliability.
