Said front divider (2) is provided on its sides with control flaps (8) for influencing amount of cleaned gravel supplied outside the rails of the traveled track (6), and said rear divider (3) rear wall has a form of a plough for leveling the ballast bed and provided with hinged sides (9) to extend ballast bed leveling area.

Description

TECHNICAL FIELD

BACKGROUND OF THE INVENTION The present invention relates to a device for distributing cleaned gravel when the track is being backfilled for machine bed cleaning.

BACKGROUND OF THE INVENTION

The currently known devices for backfilling the track with cleaned gravel are provided with long conveyors which oscillate in a horizontal plane in the space above the track and which convey the cleaned gravel into the space of its rail bed. In some cases, these devices are further supplemented with devices for spreading cleaned gravel under the rail grate.

However, the ballast bed formed by these devices is untreated and must be further treated. A further disadvantage of the known devices is also that they have to manually regulate both the amount of cleaned gravel to be discharged and the place where it is to be discharged.

SUMMARY OF THE INVENTION

The aforementioned drawbacks are eliminated by a device for distributing cleaned gravel, when underfilling the running track in the mechanical cleaning of the track bed, according to the invention, which consists in that it consists of a satellite car moving by roller rolls on the running track and pulled by a working machine. on which a dual-band track-type underfill system consisting of a front divider is provided for introducing the cleaned ballast just outside the rails of the track, which, together with the longitudinal continuous hopper, is connected via a hopper to a conveying machine a rear divider is connected, for introducing the cleaned gravel first into the space between the rails of the running track and immediately into the space of its sleepers heads.

The device further comprises the fact that the front divider is provided with regulating flaps on its sides for influencing the amount of cleaned ballast supplied outside the rails of the running track, and that the rear divider has its rear wall adapted to form a gravel bed pivoted side, for widening the gravel bed leveling range.

It is also essential for the device that the rear divider is provided with a brush for cleaning the upper surfaces of sleepers and rail fasteners of the running track.

a reversible cross conveyor for transporting in the rear divider of excess cleaned gravel behind the sleeper heads of the running track.

An advantage of the device thus formed is that the underfloor of the running track takes place in two phases and that all the elements of the cleaned gravel distributor are arranged on a separate satellite carriage. This ensures that the discharge elements of the cleaned gravel are always symmetrical with respect to the track axis, regardless of whether the track is straight or curved in the section.

SUMMARY OF THE DRAWING

The apparatus for distributing cleaned gravel in the underfloor of the running track in the mechanical cleaning of the track bed according to the invention is shown in the accompanying drawings, in which: Fig. 1 shows a general schematic side view of the device; 1 and FIG. 3 is a cross-sectional view taken along line BB of FIG. 1.

EXAMPLES OF EMBODIMENTS OF THE INVENTION

The apparatus for distributing cleaned gravel, when underfilling the running track 6 in the mechanical cleaning of the track bed, consists of a satellite trolley 1, moving by means of roller rolls on the running track 6 and pulled by a working machine. from the front divider 2, for introducing the cleaned gravel just outside the rails of the running track 6. which, together with the longitudinal continuous conveyor 4, is connected via a hopper 7 to a transfer conveyor of cleaned gravel from a working machine, the rear divider 3 is connected to the output of the longitudinal continuous conveyor 4.

The front divider 2 is provided with regulating flaps 8 on its sides to influence the amount of cleaned gravel fed outside the rails of the running track 6, the rear divider 3 having its rear wall adapted to form a gravel bed pivoted side 9 to extend engagement leveling the ballast bed.

The rear divider 3 is also provided with a sweeping device, with a directional flap 10 at its inlet. A reverse cross conveyor 5 is then arranged downstream of the rear divider 3.

• «• · *>

> Underfilling of the track 6 with cleaned gravel takes place in two phases, first by the front divider 2 and then by the rear divider 3. Between the two dividers 2, 3 there is arranged on the satellite trolley I a continuous tank 4 of cleaned gravel, which ensures its transport from the front divider 2 to the rear divider 3. at the same time it can serve to accumulate or replenish the cleaned gravel if necessary, especially at the beginning and end of the operation of the plant.

The front divider 2 provides the necessary backfilling of the running track 6 up to the upper surface of the sleepers to maintain its geometric position outside the rails. It is designed as a discharge shaft with discharge openings arranged just above the upper surfaces of both end sections of sleepers. Drainage of the cleaned gravel from the front divider 2 proceeds through the interstage areas, until the next discharge of the cleaned gravel is limited by the filling of a given place of the rail bed with the cleaned gravel and on the other hand by the flow angle of the cleaned gravel.

The rear divider 3 provides backfilling of the running track 6 also up to the level of the upper sleeper area, first between the rails and immediately in the space behind the sleepers end. It is again designed as a discharge shaft with discharge holes. Again, the amount of the cleaned gravel spilled is automatically reduced by filling the given location of the rail bed with the cleaned gravel and on the other hand by the grit angle of the cleaned gravel. The rear wall of the rear divider 3, on which the sweeper can be placed, for cleaning the upper surfaces of the sleepers and rail fasteners, constitutes a gravel plow for roughly leveling the gravel bed surface. In order to extend the width of the plow, both side parts of the rear divider 3 can be provided with hinged sides 9.

If there is an excess of cleaned gravel during the operation of the device in the rear divider 3, it will fall on the cross conveyor 5, which will transport it beyond the ends of the sleepers, either left or right.
