Description

The invention relates to railway transport and can be used when replacing a long rail sleeper lattice delivered to the place of installation in assembled form during major repairs of the track.

A known method of re-laying the rail-sleeper lattice of the railway track, which consists in the fact that the new rail and sleeper lattice is delivered to the place of laying in an inclined position on the platforms of the first track stacker and placed horizontally, the first and second track layers are placed on the existing path near the ends of the old rail and sleeper to be replaced, then raised the ends of this grate by the first and second track layers; on the first track layer, the end of the old grid is joined with the end of the new rail-sleeper, and on the second At the track layer, the other end of the old rail and sleeper grid is fixed in horizontal position, after which the ends of the old rail and sleeper grid are moved in opposite directions, thus tearing the old rail and sleeper grid from the base and hanging it between the two track layers, then move the joint by joint to the continuous old and new rail and sleeper lattices on the second track layer, moving until a new rail-sleeper lattice is completely located in the hanging position hell with the place of laying, after which its end is horizontally fixed on the first track stacker, and the old on the second track stacker and its platforms, after which the joint of the new and old grating is undocked, the ends are unfastened and the whole new rail-sleeper grating is lowered to the laying place, after which it is joined with the existing one by way.

Bondarenko (analogue)].

The disadvantage of this method is that when moving from horizontal to vertical and from vertical to horizontal, large mechanical stresses arise in the lattice elements, which can lead to destruction of the integrity of the rail-sleeper lattice.

A known method of re-laying the rail-sleeper grid of a railway track is that the track stacker is loaded with a new long grid so that one cell on the platforms remains free, after the track stacker arrives at the work site, disconnect one platform from both ends, disconnect the previously laid track from the old rail and sleeper grid, track layer with a new rail and sleeper grid is fed to the beginning of work, the end of the old grid is raised from a horizontal position with rotation vertical in a plane parallel to the axis of the track, to the level of the track stacker platforms and move the track stacker into the area of the old grate being replaced, as the track stacker rolls from the track to the first section, it is transferred from the rail to the crawler track, moving the track stacker under the old rail-sleeper grid, it remains stationary relative to the base occupying a free cell on the platforms, the tracker stops and joins the ends of the new grate on the one hand with the end of the previously laid path, on the other with the end of the gratings and the removed path, the operation is then repeated.

The disadvantage of this method is that when moving from horizontal to vertical and from vertical to horizontal, large mechanical stresses arise in the lattice elements, which can lead to destruction of the integrity of the rail-sleeper lattice.

This technical solution is selected as a prototype.

The technical result is to increase the method of re-laying the rail-sleeper lattice of the railway track, efficiency by reducing mechanical stress in the elements of the lattice.

The technical result is achieved by the fact that in the method of re-laying the rail-sleeper lattice of the railway track, namely, that the stacked rail-sleeper lattice is placed on the rolling stock in a vertical position, the end of the new rail-sleeper lattice is deployed in a horizontal position, joined with the previously laid rail-sleeper lattice, and the rolling stock is withdrawn from under the rail-sleeper lattice located on it in a vertical position, the other end of the rail-sleeper lattice is joined with an unremovable rail-sleeper with the lattice according to the invention, the old rail-sleeper grid is unfolded from horizontal to vertical position on the laying crane and adjoining platforms equipped with a rotary device, then the new rail-sleeper lattice is expanded from vertical position to horizontal on the laying crane and adjoining platforms equipped with a rotary device , and lower the crane onto the base of the track horizontally located end sections of the rail sleeper.

These actions distribute the arising mechanical stresses in the elements of the rail-sleeper lattice when they are transferred from a horizontal position to a vertical one and vice versa, which helps to maintain the integrity of the lattice.

Figure 1 - diagram of the transport position.

Figure 2 is a diagram of the removal of sleeper rail.

Figure 3 - layout of the rail sleeper.

Figure 4 is a diagram of the end of laying the rail sleeper.

The method is implemented by the following mechanisms:

1 - railway platform; 2 - a platform with a mechanism for turning the lattice from a vertical plane to a horizontal plane and vice versa; 3 - a new rail-sleeper grid; 4 - old rail-sleeper grid; 5 - crane; 6 - the existing path; 7 - rail stroke; 8 - combined stroke (e.g. pneumowheel); 9 - previously laid rail-sleeper grid.

The method of re-laying the rail-sleeper lattice is implemented as follows:

- railway platforms 1 are vertically loaded with a new long grid 3 so that one of the cells on the platforms remains free (Fig. 1);

- move railway platforms with rail-sleeper to the place of work;

- undock the old grille 4 with the previously laid grille 9;

- horizontally raise the initial section of the old rail-sleeper lattice 4 using a crane 5, translate it from a horizontal position to a vertical one using a rotary device;

- move the composition under the replaceable old grill 4, when moving the old rail-sleeper grill is transferred using platforms with a rotary device from horizontal to vertical position;

- the old lattice 4 occupies a free cell on the platforms 1 (Figure 2);

- when the carts with the crane 4 move, the platforms switch from rail 7 to the combined 8th stroke (for example, a pneumowheel stroke can be taken as a combined stroke) (Figure 2);

- the movement of the old rail-sleeper 4 on the platforms 1 is carried out by rolling the platforms under the old rail-sleeper 4, which remains stationary in relation to the base on which it was laid (Figure 2);

- after loading the entire old rail-sleeper grid 4 platforms are stopped;

- the initial section of the new rail-sleeper lattice 3 is transferred from a vertical to horizontal position on the crane and several platforms adjacent to it, lowered to the base of the track using the crane 5, horizontally (Figure 3);

- join the new rail-sleeper grid 3 with the previously laid grille 9 (Figure 3);

- platforms are removed from under the new rail-sleeper grid 3, when moving a new rail-sleeper grid is transferred using platforms with a rotary device from a vertical position to a horizontal one;

- as the platform 1 and 2 move, they again switch from combined stroke 8 to rail 7;

- the end of the new rail-sleeper grid 3 is lowered using a crane 5 and joined with the existing path 6 (Figure 4).

The proposed method for replacing the rail-sleeper lattice allows reducing the “window” time, labor required for major repairs of the track, downtime of the trains during repair work, and reducing mechanical stresses arising in the rail sleeper when moving from a vertical position to a horizontal one and vice versa.
