The invention relates to railway transport and can be used when replacing the long rail and tie lattice delivered to the place of laying assembled during major overhauls path.

There is a method of relaying rail-sleeper grid of the railway track, which consists in the fact that the new rail and tie bars are delivered to the place of laying in an inclined position on the platforms of the first railway track-laying machine and have horizontally, the first and second track laying placed on the existing road near the ends of the old rail-sleeper grid, subject to change, and then raise the ends of the lattice of the first and second track laying on the ground tracklayer machine join the end of the old lattice with the end of the new rail and tie bars, and on the second railway track-laying machine the other end of the old rail-sleeper grid is fixed in a horizontal position, then move the ends of the old rail-sleeper grid in opposite directions, tearing so old rail and tie bars at the bottom and lifting it between two track-laying units, then move the joint through the joint in continuous old and new rail and tie bars on the second railway track-laying machine, moving to produce until a new rail and tie grille is not entirely located in the hanging position over m is a shrub installation, then end it horizontally fixed on the first railway track-laying machine, and the old on the second railway track-laying machine and its platforms, then rasstropyvajut the junction of the old and new grids, raskrepljajut the ends and put all new rail and tie grille styling, after which it connect to the existing path. [Author's certificate No. 1139788, CL EV 29/02 from 15.02.85,, bull. # 6 "How long relaying rail-sleeper grid railroad", the authors Have and Youpornco (analog)].

The disadvantage of this method is that when translating from horizontal to vertical and from the vertical to the horizontal having a large mechanical stresses in the elements of the lattice, which can lead to the destruction of the integrity of the rail and tie bars.

There is a method of relaying rail-sleeper grid railroad tracks, namely, that the tracklayer machine download new long bars so that one cell on platforms remains free after the arrival of the railway track-laying machine to the place of work on both ends of the disconnect on one platform, rasstropyvajut earlier laid the path with the old rail and tie bars, railway track-laying machine with new rail and tie bars served to the beginning of works, the end of the old grille is lifted from the horizontal position when OBOROTOM in a vertical plane, parallel to the axis of the path, to the level of the platforms of railway track-laying machine and move the tracklayer machine zone replace the old grille, as the inserting of railway track-laying machine of the way, the first section is transferred from rail to track progress, moving under the old railway track-laying machine rail and tie bars, it remains stationary relative to the base, occupying free cell platforms, railway track-laying machine stop and produce the mating ends of the new grid on the one hand with the end of the previously laid path, and with the end of the grate removable way, the next operation is repeated. [Author's certificate No. 1379394, CL EV 29/02 from 07.03.88,, bull. No. 9-Way relaying rail-sleeper grid railroad", the authors Have and Namzadi]

This solution is chosen as the prototype.

The technical result is to increase the way relaying rail-sleeper grid railroad tracks, efficiency by reducing mechanical stresses in the elements of the lattice.

Technical result is achieved by those who, that way relaying rail-sleeper grid railroad tracks, namely, that stacked rail and tie bars placed on the rolling stock in a vertical position, the end of the new rail-sleeper grid deploy in a horizontal position, join it with the previously laid rail and tie bars, remove the rolling stock of below it in the vertical position of the rail-sleeper grid, the other end of the rail and tie lattice join with a fixed rail and tie bars according to the invention, unfold the old rail and tie bars from horizontal to vertical laying on the crane and the adjacent platforms, equipped with a turning device, and then deploy the new rail and tie bars from a vertical position horizontal laying on the crane and the adjacent platforms, equipped with a turning device, and lowered by a crane onto the path horizontally spaced end sections of the rail and tie bars.

These actions distribute Voznesenie mechanical stress in the rail and tie elements of the lattice when they transfer from horizontal to vertical and Vice versa, which helps to preserve the integrity of the grid.

Figure 1 - scheme of the transport position.

Figure 2 - SchemaName rail and tie bars.

Figure 3 - laying rail and tie bars.

Figure 4 - scheme of the end of the laying of rail-sleeper grid.

The method is implemented by the following mechanisms:

1 - train platform; 2 - platform mechanism to rotate the grating from the vertical plane to the horizontal plane, and Vice versa; 3 - new rail and tie grille; 4 - old rail and tie grille; 5 - valve; 6 - existing path; 7 - speed rail; 8 is a combined course (e.g. pneumatic); 9 - previously laid rail and tie grille.

The way relaying rail-sleeper grid is implemented as follows:

- train platform 1 vertical load new long bars 3 so that one of the cells on the platforms remains free (1);

- move the train platform with a rail and tie bars to the place of work;

- rasstropyvajut old bars 4 with the previously laid grating 9;

- raise horizontally initial section of the old rail-sleeper grid 4 by means of a crane 5, translate it from horizontal to vertical using the rotator;

- move the part under replace the old grille 4, when moving the old rail and tie the grating is translated using the platforms to the rotary device from horizontal to vertical;

the old grille 4 is a free slot on platforms 1 (Figure 2);

- when driving trucks with crane 4 platform are transferred from the rail 7 on a combined 8 stroke (for example, as a combined course may be taken pneumatic stroke) (Figure 2);

movement of the old rail-sleeper grid 4 of the platform 1 is carried out by rolling platforms under the old rail and tie bars 4, which remains fixed relative to the basis on which it was placed (Figure 2);

after loading all the old rail-sleeper grid 4 platform stop;

- the initial phase of the new rail-sleeper grid 3 are moved from a vertical to a horizontal position on the crane and the adjacent multiple platforms, is lowered to the base of the crane 5, horizontally (Figure 3);

- join a new rail and tie bars 3 with the previously laid grating 9 (3);

platform deduce from the new rail-sleeper grid 3, the motion of new rail and tie bars is transferred via platforms with a turning device from a vertical to a horizontal position;

- as the movement of the platform 1 and 2 again go with a combined stroke on 8 track progress 7;

- the end of the new rail-sleeper grid 3 is lowered by crane 5 and join with the existing through 6 (Figure 4).

The proposed JV is the property of rail and tie replacement grille reduces the time "window", the effort required for overhaul of the way, the downtime of trains during production, repair work, to reduce mechanical stresses, Voznesenie in the rail and tie bars when moving it from a vertical to a horizontal position and Vice versa.

The way relaying rail-sleeper grid railroad tracks, namely, that stacked rail and tie bars placed on the rolling stock in a vertical position, the end of the new rail-sleeper grid deploy in a horizontal position, join it with the previously laid rail and tie bars, remove the rolling stock of below it in the vertical position of the rail-sleeper grid, the other end of the rail and tie lattice join with a fixed rail and tie bars, wherein deploying the old rail and tie bars from horizontal to vertical laying on the crane and the adjacent platforms, equipped with a turning device, and then deploy the new rail and tie bars from a vertical position in horizontal laying on the crane and the adjacent platforms, equipped with a turning device, and lowered by a crane onto the path horizontally spaced end sections of the rail and tie bars.
