Abstract

This invention relates to devices for distributing railway ballast. The purpose of the invention is to increase the efficiency of the machine by ensuring the redistribution of ballast within the gauge and reducing the time of the plow rearrangement. The machine for distributing the ballast of the railway track contains a self-propelled crew, on the frame of which a truss is mounted that can be moved in a vertical plane by a drive. A tunnel-shaped slab 12 for protecting the rails 13 from ballast, located on both sides of the longitudinal axis 8 of the machine, is installed on the truss. In the middle part of each plate 12, an axis is rigidly fixed on which the bracket 17 is rotatably supported by the actuator 18. On the bracket 17 there is a guide on which the plows 21 are mounted for the vertical movement of the actuator 20 and the plows 21 are equal in length and adjoined to each other one ends along the axis of symmetry of the machine. At the extreme positions, the plows 21 abut against the wings 22 fixed to the plates 12, forming a straight line with them. Flaps 24 are installed on the wings x 22 with the possibility of turning around the axes 23. 5 Il.

Description

The invention relates to railway track repair devices, in particular to ballast distribution devices.

The purpose of the invention is to increase the efficiency of the machine by ensuring the redistribution of ballast inside the rings and reducing the time of the plow rearrangement.

FIG. 1 shows a machine for distributing ballast of a railway track, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 - transport position of the machine plows; in fig. 5 - position of the machine plows during ballast distribution; figure 6 - one of the provisions of the plows.

The machine for distributing the ballast of the railway track contains a self-propelled crew 1, on the frame 2 of which the power plant 3 is mounted, connected through gear 4 with cardan shafts 5, 6 and 7. On the frame 2 on both sides of the longitudinal axis 8 of the machine are installed side plows 9, pivoted relative to the frame 2 drives 10.

In the middle part of the machine, a central plow 11 is installed, which consists of two tunnel-shaped plates 12 to protect the rails 13 from ballast placed on both sides from the longitudinal axis 8 of the machine and connected between the plate 14 and the farm 15. In the middle part of each tunnel-like plate 12, there are axes 16 fixed on them, on which are mounted with the possibility of rotation in the horizontal plane of the crimping brackets 17 connected with the drives 18 of their rotation.

The brackets 17 have guides 19, on which plows 21 are mounted with the possibility of vertical movement by actuators 20, the plows being equal in length and in plan correspond to the chords of the circles to the movement of the plows.

The length of the chord of a circle of radius R of each plow is determined by the formula

(R-a7,

where L is the length of the plow,; sorting i and the chord of the circle of displacement of the plow having a radius R;

R is the radius of the circle, equal to the distance between the axis of rotation of the support and the axis of the railway track;

a is the value corresponding to the distance from the inner part of the tunnel-like plate to the axis of rotation of the support.

Moreover, the extreme points of the plows 21, when the brackets 17 rotate in the horizontal plane, move around a circle of radius R.

At their extreme positions, the plows 21 abut against the wings 22 fixed on plates 12, forming a straight line with them. Flaps 24 are mounted on the wings x 22 with the possibility of turning around the axes 23.

Farm 15 is driven by drive 25 to the transport position.

The machine works as follows.

The drive 25 of the farm 15, the carrier plate 12 and the plows 21, is lowered into the working position.

In order to perform the ballast redistribution by the drive 20, the plows 21 are lowered into the working position. The brackets 17 by the drives 18 are then set in the appropriate position. The wing flaps 24 are also positioned. When the plows are in position according to FIG. 6, the ballast is redistributed within the track from the rails to the axis of the track, as shown in FIG. 5 (a, b) - respectively

but on the left and right sides of the track, inside the track, as shown in FIG. 5 (c, d) - respectively on the right and left side of the gauge from the interrail space. When the plows are in position 21 according to FIG. 5e, the ballast is redistributed from the left side of the track to the right side, as shown in FIG. 5e from the right side of the path to the left, according to FIG. 5g - from the middle of the track and both sides of it. When the plows are in position 21 according to FIG. 5 (C, I) redistribute the ballast, respectively, from the sides to the inside of the track and level it on the left and right side of the track. With the position of the plows 21 of FIG. 5 (g, h) they are adjacent to each other by one ends along the axis of symmetry of the machine.

The machine can perform these operations when it moves in the opposite direction, with the plows 21 being moved from the position of FIG. 5g to the position of FIG. 5e automatically due to the effect of ballast on their ends when the car starts moving in the opposite direction. The plows 21 are deployed around the axes 16 and pressed against another pair of wings 22 (shown in dotted lines in Fig. 2).

When the machine is moved to the transport position, the plows 21 are mounted and fixed in accordance with FIG. 4, which makes it possible to bypass the driveshaft 6 when lifting the plow 11.
