Description

Pedestrian crossing over the rail track.

The utility model relates to transport construction and is intended for the construction of pedestrian crossings through railway tracks at the intersection of railway and pedestrian roads. The design of the flooring for the railway pedestrian crossing contains elements of rubber compound with fibrous filler and metal fastenings connecting them, and is universal for use on reinforced concrete and wooden sleepers of various designs and various types of rail fasteners.

Known rail crossing of rubber panels (RU 22450098 C2, 07.26.2010), consisting of external and internal rubber panels laid on both sides of each rail, connected to each other in the longitudinal direction along the axis of the rail track with metal ties, inside which the rods are placed, connected at the ends of the crossing with the rails, and in the transverse direction are connected by fasteners, which are metal I-beams, the shelves of which are included in the grooves made when forming the panels on their end faces. Couplers pass in round openings of two-Tauri and in the open channels formed in an array of panels.

The disadvantages of this design are:

- a complex and non-technological form of grooves on the side ends, repeating the shape of one half of an I-beam, cut along the vertical axis of symmetry;

- complex construction and laborious assembly of tightening parts;

- laborious assembly of the inner panels due to their design, which provides for laying two panels on two adjacent sleepers (one sleeper box) with the rear sides facing each other, if necessary, the coincidence of the side ends to form a common groove for installing the I-beam metal element.

Closest to the claimed technical solution is a deck for crossing the rail track and its elements (RU 2332536. C2, 05.24.2006), made in several versions, having plates of elastomeric materials installed inside and outside on both sides of the rail track, based on gaskets and liners made of elastomeric materials. Using various liners and gaskets, it is possible to install on wooden and reinforced concrete sleepers. Docking of plates occurs in several ways: by the principle of a tenon (protrusion) into the groove, a tenon to the tenon with the remaining space overlays with overlays, a tenon to the tenon through an intermediate insert with holes. To keep the plates in the assembled state at the ends of the flooring, installation of stops is provided, which are installed on wooden boards laid in several inter-sleepers, specially for this purpose cleared of a layer of gravel.

The disadvantages of this design are:

- the presence in one of the options for the design of parts - liners (items 4, 5, 11, 12), which are installed on the fastening nodes of rail fasteners, which leads to an increase in the complexity of installing the flooring;

- fastening the assembled flooring using end stops (pos. 13) increases the complexity of installing the flooring due to the need to release several sleeper boxes (inter-sleepers) from gravel at both ends of the flooring;

- in one of the options, when installing on reinforced concrete sleepers, the outer slabs (item 3) do not rest on the sleepers, but on a layer of gravel poured on the sleepers and into inter-sleepers, which greatly complicates the installation of the outer slabs, because there is no basic supporting surface in the form of a sleeper, and a layer of gravel must be arranged of a certain limited height, bringing the surface of the layer to a horizontal level so that the outer plates are laid without slopes and the height of their location ensures the correct docking with the rail.

The task to be solved by the claimed utility model is:

- the creation of a reliable, durable flooring designed for laying at pedestrian crossings through railways.

- unification of the design for laying on wooden and reinforced concrete sleepers with various types of rail fasteners.

- improving manufacturability and reducing the complexity of installation and dismantling of the structure

- increase in service life.

- reducing the cost of flooring through the use of special materials and structural solutions.

The technical result is to increase the reliability and strength of the flooring structure.

At the same time, an increase in manufacturability and a decrease in the complexity of installation and dismantling of the structure are achieved.

The claimed technical result is achieved by the fact that in the deck for a pedestrian crossing over a rail track containing interconnected internal plates in which open channels are made, grooves are made on the side faces of internal plates in which metal profiles are installed with openings, open channels and openings the profiles are mounted parallel to the axis of the rail track of the stud, tightening the inner plates together, while the plates are made of rubber compound with fibrous filler.

It is preferable in the longitudinal direction on both sides of the outside of the rail track to have outer plates.

It is rational to make open channels in the outer plates, to make grooves on the end faces of the outer plates, in which to install profiles with holes, and in open channels and openings of the profiles to place studs installed parallel to the axis of the rail track, tightening the outer plates together.

It is recommended that the pedestrian crossing over the rail track be additionally provided with linings made of a rubber mixture with a fibrous filler installed between the sleepers and plates, while the supporting surfaces of the linings should be similar to the shape of the sleepers.

It is recommended that the pedestrian crossing over the rail track be additionally equipped with bars installed in the open channels of the inner plates parallel to the axis of the rail track, while the bars are made of rubber compound with fibrous filler.

Optionally, the width of the outer plates and linings is a multiple of two interaxal distances between the sleepers.

It is advisable to apply a tread layer made of wear-resistant rubber to the outer and inner plates and perform it with corrugations.

It is rational to install washers and nuts at the ends of the studs.

The claimed combination of features allows you to create a solid and reliable design of the flooring for a pedestrian crossing over the rail track.

The execution of open channels in the inner and outer plates, on the side faces of the inner plates and the end faces of the outer plates of the grooves in which the square metal profiles with holes are installed, the placement in the open channels and holes of the square metal profiles of pins mounted parallel to the axis of the rail track and tightening the inner plates and external plates, allows to increase the strength and reliability of the joining of structural elements of the flooring by strengthening the junction of the connected plates. At the same time, the use of a rubber mixture with a fibrous filler as a material while increasing the cost of flooring helps to increase the strength and reliability of the flooring.

The floor for a pedestrian crossing over the rail track comprises inner plates 1 located in the transverse direction inside the rail gauge, and outer plates 2, 2a located in the longitudinal direction outside on both sides of the rail gauge.

External slabs can be made single 2, double, 2a), built, etc., depending on the width of the flooring for a pedestrian crossing.

A pedestrian crossing can have a base width with single outer plates 2 and an increased width with double outer plates 2a. The inner plates 1 and the outer plates 2, 2a are supported on sleepers 16, pads 3, 3a, 4, 4a, bars 6, 6a and form a surface for pedestrian traffic. The pads 3 are used to install the inner 1 and outer 2 plates on a wooden railroad tie with a crutch rail fastening for a single (Fig. 2a)) and double (Fig. 2b)) outer plate. The liners 4 and 4a are used when installing on a reinforced concrete sleepers with separate rail fastening (Fig. 3a), 3b), the linings 5 and 5a are used when installing on a reinforced concrete sleepers with inseparable rail fastening (Fig. 4a), 4b) single 2 and double 2a outdoor plates.

The outer single plates 2 are installed on the pads 3, 4, 5, and the outer double plates 2a are installed on the pads 3a, 4a, 5a (Fig. 3a), 3b), FIG. 4a), 4b)).

The inner plates 2 have open channels, and grooves 12 are made on their side faces (Fig. 5 (b)), in which metal profiles 8 with holes are installed. In the open channels 13, made, for example, through and holes of the profiles 8 are placed mounted parallel to the axis of the rail gauge metal studs 9, tightening together the inner plates 1.

Inner 1 and outer 2, 2a plates (Fig. 6d), 6e)), bars 6, 6a (Fig. 8c), 8g)), linings 3 (Fig. 7a), 7b)), linings 4, and 4a ( Fig. 7c), 7 g), Fig. 8a), 8b)), the linings 5, 5a (Figs. 8, 8a)) are made of a rubber mixture with a fibrous filler.

In the inner plates 1 there are made transverse transverse grooves 10, 11 for accommodating the bars 6, 6a (Fig. 5) and transverse transverse channels 13 (Fig. 6a)) for accommodating metal studs 9.

In the outer plates 2a, open channels 15 are also made, made for example through and longitudinal (Fig. 6c), and grooves 14 are made on their end faces (Fig. 6d), in which profiles with holes are installed, for example, made in the form of a channel 7, while in the open channels 15 and the holes of the profiles (not shown in the drawings), studs 9 mounted parallel to the axis of the rail track are arranged, tightening the outer plates 2. The width of the outer plates 2 and the liners is a multiple of two interaxal distances between the ties 16. At the ends of the studs 9 installed washers and nuts (not shown).

On the outer 2 and inner 1 plates applied tread layer with corrugations made of wear-resistant rubber (not shown in the drawings).

The flooring for the railway pedestrian crossing (Fig. 1, 2, 3, 4,) is mounted as follows.

On the sleepers 16, depending on their type and on the width of the transition, the corresponding pads 3, 4, 5 or 3a, 4a, 5a are laid (Fig. 3, 4), FIG. 7, 8) and bars 6 or 6a (Fig. 3, 4, Fig. 8c), 8 g)), on which internal plates 1 (Fig. 5) and external plates 2 or 2a) are installed (Fig. 6e), 6e)). The combination of internal plates 1 with linings 3, 3a) and external plates 2, 2a) with linings 3, 3a), 4, 4a), 5, 5a) when they are installed is done according to the tenon-groove principle, while the spikes on the linings are aligned with grooves in the plates. The internal plates 1 are installed on the bars 6 or 6a (Figs. 2, 3, 4) with slots 10 and 11 (Fig. 5). Square metal profiles 8 (Fig. 1, 2, 3. 4) are installed in the p-shaped grooves 12 (Fig. 5b)) of the inner plate 1 so that the holes in the profiles are located opposite the open through channels 13 of the inner plate 1. Metal channels 7 are installed in the p-shaped grooves 14 (Fig. 6a)) of the outer plate 2a so that the hole in the channel 7 is located opposite the open through channel 15 of the outer plate (Fig. 6c). A metal stud 9 is installed through holes in square metal profiles 8 and metal channels 7 (Fig. 1) and is located inside open channels of the pos. 13 (Fig. 5a)) and pos. 15 (Fig. 6c)). Washers are put on the ends of the studs 9 on both sides and nuts are screwed on (not shown in the drawings), tightening the inner plates 1 together and preventing a gap between them (Fig. 1a), 1b)). The outer plates 2a are bonded together in a similar manner (Fig. 1a)).

Depending on which railroad tie and type of rail fastening the flooring is installed in, various parts are used in the assembly. For installation on a wooden railroad tie with a crutch rail fastening, the installation of internal plates 1, lining 3 or 3a and external plates 2 or 2a (Fig. 2). For laying on reinforced concrete sleepers with separate rail fastening, bars 6 or 6a, linings 3 or 3a, linings 4 or 4a of the inner plates 1 and the outer plates 2 or 2a are installed. When this bars 6 or 6A are installed in the grooves 11 of the inner plate 1 (Fig. 5). For laying on reinforced concrete sleepers with inseparable rail fastening, bars 6 or 6a, linings 5 or 5a, internal plates 1 and external plates 2 or 2a are installed. When this bars 6 are installed in the grooves 10 of the inner plate (Fig. 5).

The proposed flooring works as follows. The flooring elements fit snugly against the rails and sleepers 16, the inner plates 1 are brought under the rail head with short sides, the outer plates 2 are brought under the rail head with one long side. For the passage of the flange of the wheels of the rolling stock on the inner plates 1 there are special gutters. Since vibrations from passing trains are transmitted to the deck during operation, over time there is a tendency for plates to move away from each other and a gap between them. In the proposed solution, the occurrence of gaps between plates 1, 2, directly affecting the safety of movement on the floor of pedestrians, is excluded, because this is prevented by the fastening of the plates to each other by metal studs 9. This connection of the plates 1, 2 by means of metal studs 9 contributes to a more stable position of the inner and outer parts of the flooring assembled together by increasing their total mass. Square metal profiles 8 and metal channels 7 make it possible to fix the studs 9 in them, strengthen the junction of the joined plates and, together with the studs 9, form a rigid frame reinforcing the flooring structure. The use of bars 6 and several types of linings allows the use of flooring on wooden and reinforced concrete sleepers with various types of rail fasteners. Plates 1 and plates 2 turn out to be connected with each other in the longitudinal direction along the axis of the rail track by metal studs passing through all the plates of the flooring, and in the transverse direction by fasteners, which are square metal profiles and channels, which are installed in the plates formed during the manufacture of them the lateral faces of the u-shaped grooves 12, 14 (Fig. 5b), Fig. 6g)).

Bars, pads and plates are made of a rubber mixture with a fibrous filler, which is obtained by processing a rubberized cord by grinding on a rotary grinder, then the crushed cord is crushed on a grinder (for example, XPZ-400) and leafed on crushing rollers. The use of a rubber mixture with fibrous filler allows not only to increase the strength of the product, but also to reduce the cost. The outer and inner plates have a tread layer made of wear-resistant rubber. The tread has corrugations in the form of, for example, rhombs or any other shape, separated by grooves to prevent slipping when walking on its surface.

Using the proposed technical solution will allow you to create a deck for a pedestrian crossing over the rail track, having a stable position of its elements relative to each other without the formation of gaps, convenient and technological installation and dismantling due to the small dimensions and mass of parts, as well as having a unified design for installation on wooden and reinforced concrete sleepers with various types of rail fastenings.
