RU2450098C2 - Rail crossing made of rubber panels - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: rail crossing consists of base, railway sleepers laid on base top, outside and inside rubber panels located at both sides of each rail, which are connected with each other by metal braces in longitudinal direction of rail axis and inside panels there are rods connected at crossing edges; in transversal direction panels are connected by fastenings made metal I-beam girders which tee-parts are inserted into moulded grooves in edges. In this solution braces will pass in round holes of I-beam girder walls and in special open channels formed in panels.

EFFECT: this solution allows creation of rail crossing with optimised rigidity of structure and dynamic integrity of rubber deck and decrease in labour intensity and cost of panels.

Description

The invention relates to transport construction, in particular to the construction of crossings with an elastic coating at the intersection at the same level of the rail track with the road.

Known rail crossing (RU 2304655 C1, 12.27.2005) with a deck of interconnected rubber panels located on the sleepers on both sides of each rail, which contains clamps of the rubber panels made in the form of vertical protrusions, motionlessly connected to their supports located on sleepers, and each of the clamps is placed in a vertical through hole of the rubber panel, linking them.

Closest to the claimed technical solution is a rail flooring made of rubber panels f. Kreiburg (Materials by f. Kreiburg on strail website). In this railroad crossing, inner panels located across the track, for their interconnection, have protrusions in the middle part on the side faces on one side and grooves on the other side, which enter each other when installing the flooring. To increase the interaction between the panels, this flooring has additional screeds that are located in the direction of the path axis and are located in the holes made in the array of panels. The design of the couplers, the length of which corresponds to the width of the panel, is a thick-walled pipe having internal and external threads at the ends, which allows, when mounting, screwing the end of one pipe to the beginning of the next, additionally tie the entire series of internal panels using a nut installed at the end of the row. For uniformity of such a connection, two holes were made in the array of the inner panel equidistant from the transverse axis of the panel.

The outer panels of this rail crossing are laid along the length along the rail and have protrusions and grooves on the side faces, and holes for connecting screeds in the array.

The rail ends of the inner panels and the rail edges of the outer panels of the rail crossing are made thin, and rail liners are brought under them, in which the sockets for the fastening points of the rail to the railroad tie are selected.

The end fastening of this crossing is made by attaching the rods passing inside the couplers to the rails behind the ends of the crossing.

The disadvantages of the design of this rail crossing are:

- the presence in the design of the flooring liners installed on the mounting nodes of rail fasteners, the manufacture of which leads to an increase in the complexity and cost of flooring;

- the presence in the array of panels through holes for screeds and rubber protrusions and grooves for joining panels, the manufacture of which is not technological and time-consuming when molding panels of crumb rubber.

The problem to which the invention is directed, is the creation of such a rail crossing from rubber panels, the design of which will reduce the complexity and cost of manufacturing rubber panels.

The solution to this problem is achieved by the fact that the railroad crossing contains a base laid on the base of the sleepers with rails fixed on them, rubber panels located on the sleepers on both sides of each rail, external and internal, connected with each other in the longitudinal direction along the axis of the rail track with metal ties inside which rods are placed, connected at the ends of the crossing with rails, and in the transverse direction by fasteners, which are metal double tees, the shelves of which are normed in the manufacture of panels on their end faces of the grooves. For internal panels located along the path axis and having a joint line along the path axis, the I-beam connects two panels along the path axis and two panels in the transverse direction, i.e. four panels. For internal panels located across the track, one I-beam will connect two adjacent panels to each other. Two adjacent outdoor panels will be connected by one I-beam.

The screeds used in the proposed solution will pass through holes in the wall of the I-beams and inside open channels specially formed in the array of panels.

The essence of the invention is illustrated in figures 1-4. Rail crossing 1 (Fig. 1) contains a base 2, laid on the base of the sleepers 3 with rails 4 fixed to them, located on the sleepers on both sides of each rail 4 rubber panels, inner 5 and outer 6, connected to each other along the axis of the rail metal ties 7 passing through the open channels 12 (figure 4) formed in the panels. In the transverse direction (FIG. 2 is a cross section), the rubber panels are connected by I-beams, internal 8 and external 9, the shelves of which are included in the grooves 10 made during molding of the panels 5, 6 at their end faces (FIG. 3). The I-beams 8, 9 have round holes 11 (FIG. 2), and the panels 5, 6 have open channels 12 formed during their manufacturing (FIG. 4).

The proposed rail crossing works as follows.

As a result of significant loads from 1 wheeled vehicles passing through the proposed rail crossing, the loosening and sliding of the rubber panels along the rails becomes impossible, since the coupler system 7 and the additional connection with the rails by means of rods (Fig. 1) passing inside the couplers and attracted by special fastening units to the heel of the rail, prevent this. The presence of the I-beams in the proposed rail crossing eliminates the vertical movement of the panels relative to each other and increases the overall rigidity of the rubber flooring.

Using the proposed technical solution will create such a rail crossing, the design of which will increase the rigidity and dynamic monolithicity of the rubber flooring, as well as reduce the complexity of manufacturing and the cost of panels by eliminating the rubber linings for rail fasteners, using metal I-beams and channels in the panel array to connect the panels.
