MACHINE FOR CLEANING BALLAST IN RAILWAY TRACK The present invention relates to railway transport and, more particularly, to machines used for cleaning ballast in railway tracks.

Widely known in the art are machines for cleaning railway ballast, comprising a track lifter and devices for trimming and cleaning railway ballast, which are positioned under this track during the course of the lifting thereof.

A disadvantage of the conventional machines lies in that during the course of the machine movement the ballast stuck in the cells of the lifted track has to be pushed through manually, which requires additional manual labor and is fraught with danger for those who carry out this operation.

It is an object of the present invention to eliminate the afore-said disadvantage.

The present invention has as its object the provision of a machine having a means for pushing through-stuck ballast which would ensure safe and more efiicient operation of the machine.

This task is accomplished by that in a machine for cleaning ballast in railway tracks having a track lifter and devices for cutting-off and cleaning ballast, which is conveyed under the track during the course of the lifting of the latter, an axle is disposed ahead of the devices for cutting-off and cleaning ballast in a direction transverse to that of the machine movement, with the axle having sleeves successively mounted thereon and being provided with pushers which are disposed radially and enter the cells of the lifted track during the course of the machine operation to push through ballast stuck therein.

It is an object of the present invention to provide a machine having a means for pushing-through ballast stuck therein that would ensure safe and more efficient operation of the machine.

The employment of the axle equipped with pushers effecting removal of ballast stuck in the track provides for greater efficiency of the machine for cleaning ballast and makes this operation safe for the personnel servicing the machine.

The following description of an exemplary embodiment of the present invention is given with reference to the accompanying drawings, in which:

FIG. 1 and FIG. 1' shows a general view of the machine for cleaning railway bed, according to the invention;

FIG. 2 shows a shaft mounting hubs and pushers of ballast, according to the invention; and

FIG. 3 shows an enlarged view of detail A in FIG. 1.

The machine for cleaning railway bed comprises trusses l and 2 (FIG. 1 and 1 which are interconnected by joints and are mounted on bogies 3,4 and 5.

The truss 2 mounts a frame 6 having an axle a shaft 7 secured thereon and having turnable sleeves 8 (FIGS. 2 and 3) which are successively mounted thereon.

The sleeves 8 have pushers 9 (FIGS 1,1 1, 1' and 2) which are disposed radially and are essentially metal spokes 10 having heads 11 (FIGS. 2 and 3) rigidly secured thereon.

Mounted on the truss 2 after the axle 7 with the pusher 9, is a device for cutting-off ballast, which comprises a shearing knife 12 (FIG. 1') and side knives 13 and 14. The shearing knife 12 has/aworking edge disposed approximately perpendicularly relative to the direction of the machine movement,- the knives 13 and 14 being designed for cutting-off ballast beyond the knife 12 edges and directing cut-off ballast thereto. 7

Mounted on the truss 2, above the shearing knife 12, is a device for cleaning ballast, which comprises a conveyor, 15, whose netted belt 16 moves in a transverse direction relative to the machine longitudinal axis.

The belt 16 of the conveyor 15 is driven by motors 17 via a drive shaft 18 with sprockets 19 and embraces tension sprockets and a roller battery (not shows in the drawings).

Also mounted on the truss 2 are lifters 20 of a track 21, driven by hydraulic cylinders 22, and a device 23 for the cleaned ballast bed, which comprises mold boards 24. v

The machine operates as follows.

The lifter 20 raises the track 21 for the devices for cutting-off and cleaning ballast to be conveyed thereunder.

One of the spokes 10 on the head 11 of each sleeve 8 is pre-set for a certain depth in a cell of the track 21, for which purpose the frame 6 is lowered and fixed in a required position. With the machine moving, the spokes 10, on having encountered a tie on their way, turn the sleeves 8, whereas a subsequent spoke 10, on having entered a next cell of the track 21, pushes the ballast stuck therein onto the track. Then, the spokes again encounter a new tie, turn the sleeves8 and a subsequent spoke 10, on having entered a next cell of the track, pushes the ballast stuck therein onto the track.

The knives 13 and 14 cut off ballast beyond the end portions of the ties and direct it onto the moving netted belt 16.

The knife 12 cuts off ballast in the middle of the track and delivers it together with the ballast supplied by the knives 13 and 14 through the surface of the knife 12 cutting portion onto the moving belt 16.

With the belt embracing the roller battery, the ballast is pressed by centrifugal forced against the belt 16, whereby the substances contaminating any fine ballast and the ballast particles are removed through holes in the belt 16.

The netted endless belt 16, moving with ahigh speed in a transverse direction with respect to the center line of the track, passes along the inner side of knife of knife 12 that cuts away the ballast and feeds it onto the belt. Next the belt passes through .slots in the truss an again retums-to the knife. Tension and guide sprockets of a roller battery (not shown in the drawing) serve to direct the motion of the. belt and tension it.

The ballast remaining I on the belt 16 is moved together therewith until it reaches the tension sprockets, whereupon, on having left the belt, the ballast is moved by inertia forces further into a hopper (not shown in the drawing) and is poured onto the track. Then, the ballast is levelled by the mold boards 24, and the track is then lowered thereon.

The centrifugalforce appearing on curved sections of the belt when it is in motion presses the ballast cut away from the track against the netted belt from inside. Under the action of the centrifugal force, the fine fractions and the foreign matter contaminating the ballast are pressed through the openings of the netted belt and are thrown to a side from the machine. The larger ballast fractions remaining inside the belt fall under the action of their own weight into a hopper (not shown in the drawing), whence they are discharged onto the track.

- What is claimed is:

1. A machine for cleaning ballast in railway tracks and provided with a track lifter, comprising: two trusses interconnected through joints; trucks supporting said trusses; a frame mounted on the second of said trusses in the direction of motion of the machine and movable in a vertical direction; an axle rigidly secured on said frame; tumable sleeves consecutively installed on said axle; pushers radially disposed and rigidly secured on said sleeves and introduced between the ties of the lifted track to push out the ballast stuck there; devices for cutting away and cleaning the ballast that are moved under said track when it is lifted and installed on the said second truss after the said frame; a device for levelling out the cleaned ballast installed on said second truss after the said devices for cutting away and cleaning the ballast; means for driving said devices and said track lifter.
