Method of re-laying of track skeletons

FIELD: railway transport; permanent way.

SUBSTANCE: invention can be used at replacement of long-length track skeleton delivered to place of laying in assembled state. According to proposed method, new track skeleton located on train in vertical plane is shifted into horizontal position. End of old track skeleton is raised and fitted into free cell on train and old skeleton is loaded on train. End of new track skeleton is lowered and butt-joined with track skeleton of previously laid track, and is placed onto base by bringing train from under the skeleton, and then other end of new track skeleton is butt-joined with previously laid track. Loading and unloading of track skeleton is effected in horizontal plane.

EFFECT: improved efficiency owing to reduction of mechanical stress in skeleton members.

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

There is a method of relaying a lengthy 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, 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-sleeper grid, and on the second railway track-laying machine the end of the old rail-sleeper grid is fixed in a horizontal position, move the ends of the old rail-sleeper grid in opposite directions (in the direction of the platforms and, respectively), tearing off the old grille off the ground and putting it between two track-laying units, moved, merged into a continuous rail and tie bars, old and new railings on the second railway track-laying machine, while the old grid will be loaded on the platform, moving to produce until a new rail and tie grille is not entirely located in the hanging position over the months the om styling, and the old rail and tie grille completely will not appear on the second railway track-laying machine, rasstropyvajut the junction of the old and new grids, raskrepljajut the end and put a new rail and tie grille styling, join the ends of the new grid with the adjacent ends of the existing path [Copyright certificate №119788, CL EV 29/02, from 15.02.85. Bull. # 6 "How long relaying rail-sleeper grid railroad" authors And and Youpornco].

The disadvantage of this method is that to move the rail-sleeper grid in the horizontal plane to the rails need to make substantial efforts, the value of which exceeds the amount of elasticity of the steel rail, which will lead to the rupture of rail lashes.

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 with the rotation in the vertical plane, a pair of the press to the track axis, to the level of the platforms of railway track-laying machine and move the tracklayer machine zone replace the old grille, as rolling of railway track-laying machine of the way on the first section of this translates to a rail of the track move, move 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 road, and with the end of the grate of an existing path, the operation then repeats [Copyright certificate №1379394, CL EV 29/02, from 07.03.88. Bull. No. 9-Way relaying rail-sleeper grid railroad" authors And and Namzadi].

This technical solution chosen by the authors as a prototype.

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 rail and tie bars.

The technical result is to increase its efficiency by reducing mechanical stresses in the elements of the lattice.

The technical result in the known method is achieved by loading the removable rail and tie bars on roaming under her mobile with the Tav and unloading stacked rail-sleeper grid with the output from under her, rolling stock are made in the horizontal plane. These actions reduce the magnitude of the resulting mechanical stresses in the elements of the rail and tie bars.

Figure 1 shows the transport position.

Figure 2 shows the removal of the rail and tie bars.

Figure 3 shows the laying of the rail and tie bars.

Figure 4 shows the completion of installation of rail-sleeper grid.

The method presented in the figures of the following positions:

1 - train platform; 2 - new rail and tie grille; 3 - the old rail and tie grille; 4 - valve; 5 - existing path; 6 - speed rail; 7 - combined course (e.g. pneumatic); 8 - previously laid rail and tie grille.

The proposed method is the replacement of rail-sleeper grid is implemented as follows:

- Train platform 1 horizontal load new long bars 2 so that one of the cells on the platforms remains free;

- translate rail and tie bars in a vertical position (figure 1);

- move the rolling stock (crane and platform) with rail and tie bars to the place of work;

upon arrival at the place of work to rail and tie bars are transferred in a horizontal position;

- rasstropyvajut old bars 3 with the previously laid grating 8;

- raise horizontally initial section of the old rail-sleeper grid 3 crane 4;

-move the platform 1 in the zone replace the old grille 3;

the old grille 3 is a free slot on platforms 1 (figure 2);

- when moving the rolling stock is transferred from the rail 6 by a combined 7 stroke (for example: as a combined course may be taken pneumatic stroke) (figure 2);

movement of the old rail-sleeper grid 3 of the platform 1 is carried out by rolling platforms under the old rail and tie bars 3, which remains fixed relative to the basis on which it was placed (figure 2);

after loading all the old rail-sleeper grid 3 rolling stock stop;

- the initial phase of the new rail-sleeper grid 2 is lowered to the base of the crane 4, horizontally (figure 3);

- join a new rail and tie bars 2 with the previously laid by 8 (3);

platform deduce from the new rail-sleeper grid 3, as the movement, rolling stock again transferred with combined turn 7 on the rail move 6;

- the end of the new rail-sleeper grid 2 is lowered by crane 4 and join to existing path 5 (figure 4).

The proposed method of the rail and tie replacement grille reduces the duration provided by "Windows", the effort required for major road repairs, downtime trains during production, repair work, to reduce the magnitude of the mechanical stresses occurred is working in the rail and tie bars in her removal and installation.

The way relaying rail-sleeper grid, which consists in the fact that the new rail and tie bars mounted on a movable structure in the vertical plane, is transferred to the horizontal position, the end of the old rail-sleeper lattice raise and charge in free cell rolling stock, loaded it on the rolling stock, the end of the new rail-sleeper grid down and join with rail and tie bars earlier laid the path, lay new rail and tie bars at the base by inference from under her, rolling stock, and connect the other end of the new rail-sleeper grid operated by, characterized in that the loading and unloading of rail and tie gratings operate in the horizontal plane.
