Definitions

  • the present invention relates to a process for the purification of ballast from railways and a machine for this purpose equipped with means for stripping the ballast, for screening it, evacuating the bad elements and recovering the reusable elements, and putting them back in way.
  • ballast screeners On the ballast screeners most used today, the purification of the ballast is done by stripping the ballast by means of an endless stripping chain which passes under the sleepers and brings this ballast either directly or through chutes and conveyors to a screening device.
  • the function of the screening device is to select the ballast elements of a determined caliber, to put them back on track, the earth and the ballast elements of a caliber less than or greater than the desired caliber being eliminated.
  • the elements of the ballast are not sufficiently cleared from the earth which surrounds them and are returned to the track, still soiled, even when their size is less than the prescribed size. It has been proposed, it is true to strip the ballast and bring it to the screening device, to use an endless stripping chain provided with scrapers and working in a plane forming an acute angle with respect to port in the plan of the railroad track, so that the stripped ballast is brought up to the screen along a side corridor of rise of the raclette chain. The longer this route, the more the elements of the ballast rolling on top of each other will tend to lose the earth that coats them.
  • the present invention aims to improve the quality without reducing the yield from the purification of the ballast, or even by increasing this yield.
  • Figure 1 is a side view of the machine.
  • Figure 2 is a section along the line II-II of Figure 1, some parts not being shown.
  • Figure 3 is a longitudinal sectional view of a first embodiment of a conveyor-separator used in the present ballast cleaning machine.
  • FIG. 4 is a top view of the conveyor-separator illustrated in FIG. 3.
  • FIG. 5 is a cross section along the line V-V of FIG. 4.
  • the process for continuously cleaning the ballast of a railway track by means of a machine equipped with a stripping and elevating device for the ballast, ballast conveyors and a device of ballast screening is distinguished by the fact that: the ballast elements of a caliber greater than a predetermined caliber are separated beforehand and the elements of the ballast of a lower caliber as well as part of the soil, that these rubbish are removed, and that the only elements of the ballast having a caliber corresponding to that predetermined are then purified and put them back on track.
  • the preselection of earth and ballast elements having a caliber lower and higher than that prescribed makes it possible to send to the main purifier of the machine only a small part of the stripped ballast (of the order of 30 to 50%) and to purify this ballast in the most efficient way possible, the purging device no longer having the function of separating the elements of the ballast into elements of different calibers, but simply of clearing the elements of the ballast of the prescribed caliber from the rest land that still coats them and evacuate that land.
  • the removal of soil and ballast elements of a caliber lower and higher than that prescribed can be done in the process according to the invention by double screening beforehand. It can also be advantageously facilitated by a double stripping of the ballast at two different depths.
  • the first stripping treating only the surface part of the ballast, the least polluted generally, the elements of the ballast thus stripped being previously separated from the soil and the elements of the ballast to a caliber lower and greater than that prescribed, before being sent to the 'purifier; the second stripping treating the deep part of the ballast, often polluted to the point of making the recovery of its elements unprofitable, the stripped material being then at will evacuated directly without even going through a preliminary screen.
  • the machine for applying the method according to the invention is a machine equipped with at least one device for stripping and elevating the ballast, ballast conveyors, ballast screening devices, evacuation devices. ballast and ballast resetting devices.
  • This machine comprises at least one screening device making it possible to eliminate the earth and the elements of the ballast of a caliber smaller than that prescribed, and the elements of the ballast of a caliber greater than that prescribed, as well as a purifier not treating than the ballast elements of a caliber corresponding to the prescribed standards.
  • Conveyors associated with the screening device make it possible to directly evacuate the earth and the elements of the ballast of a caliber lower and greater than the prescribed caliber, other conveyors bringing the elements of the ballast whose caliber corresponds to the prescribed standards to the purifier. , as well as means allowing the re-routing of the refined ballast.
  • the illustrated machine used for the stripping of the track, the sorting of the ballast components, the purification of the ballast and the resetting of the elements of this ballast to the desired caliber comprises a chassis 1 mounted on bogies 2 rolling on the rails 3 of the railway.
  • FIG. 1 illustrates only part of this machine, that presenting the various stripping and sorting bodies of the ballast.
  • the machine illustrated is self-propelled or towed along the track by a railway vehicle in the direction of arrow F.
  • This machine has at least one device stripping and elevation of the ballast to the upper part thereof.
  • the two functions of this device can be performed either by separate units, stripping means followed by a stripped ballast conveyor, or by a single unit as is the case in the machine described with reference to the drawing.
  • These ballast stripping and raising devices can strip the ballast located over the entire width of the track, as is the case with the machine illustrated, or the ballast of the shoulders of the track.
  • the machine illustrated comprises two stripping and raising devices for the ballast, each comprising an endless stripping chain 4.5 working at different depths in the ballast 6.
  • Each of these endless 4.5 stripping chains comprises, in known manner, a number of links provided with pallets, scrapers or buckets.
  • the lower part of the path of these chains is arranged under the track and in operation scrapes the ballast laterally then drives it in vertical corridors 7.8 surrounding the chains to the upper part of the path of these where the ballast is stripped and driven falls by gravity on conveyors 9.10 associated with each of the chains 4.5 respectively.
  • the chain 4 works at a depth at which the ballast 6 is not too polluted and a large part of the elements can be reused.
  • This chain moves in the vertical corridor 7 in the direction of the arrow G, raises the stripped ballast to the upper part of the machine and deposits the stripped ballast by gravity on it on the conveyor 9.
  • the stripped chain 5 works at a greater depth than the chain 4 and strips the lower layer of the ballast 6 which is sometimes polluted by so much that it is no longer worth separating the elements for reuse.
  • This stripping chain 5 moves in the corridor 8 in the direction of arrow H, in a direction of rotation opposite to that of the chain 4, which balances the lateral forces transmitted to the chassis 1, raises the stripped ballast to the upper part of the machine and delivers by gravity the ballast which it strips on the conveyor 10.
  • the stripping chains 4,5 are driven in their movement by motors 11,12 in a conventional manner.
  • the conveyors 9 and 10 are driven by reversible motors (not shown) so that, at the user's choice, each conveyor can be driven in one direction or the other.
  • the conveyor 10, associated with the deep stripping chain 5 is driven in a direction such that this deep part of the ballast, generally non-reusable, is directly eliminated and transported to the silos by the conveyors 13 and 14.
  • the machine further includes a screening device making it possible to remove the earth and the elements of the ballast of a caliber smaller than that prescribed, as well as the elements of the ballast of a caliber greater than that prescribed.
  • This screening device could be constituted by a conventional type screen with two stages. However, in the illustrated embodiment of the machine, this screening device is formed by two separate screens.
  • the screening device of the illustrated machine comprises a first vibrating screen 16 mounted on the chassis 1 and vibrated by a motor 17.
  • This first screen is located under the other end of the conveyors 9,10 and receives the elements of the stripped ballast along the direction of movement of these conveyors 9,10. Generally, only the ballast stripped by the shallow chain 4 transported by the conveyor 9 is poured into this first screen 16.
  • This first screen 16 comprises meshes of a size such that only the elements of a caliber greater than the desired caliber for the resetting are retained.
  • This screen 16 therefore makes it possible to quickly eliminate “cat heads” and other excessively large elements from the bald ballast. These large elements of the ballast retained by this screen 16 fall by gravity onto the discharge conveyor 13 and are therefore eliminated.
  • the rest of the elements of the ballast pass through the first screen 16 and fall by gravity onto a second screen of the screening device constituted by a conveyor-separator 18 which will be described in detail with reference to FIGS. 3 to 5.
  • This second screen lets the earth pass and all ballast elements of a caliber less than the prescribed caliber. These small elements fall by gravity onto a conveyor 19 driving the elements of the ballast that it receives in the direction of arrow K and deliver them to the discharge conveyor 13 for their evacuation.
  • ballasts at the prescribed caliber and purified of the earth which coated them are poured out of the purifier on or into re-routing means, here a re-routing conveyor 21a, 21b discharging the purified ballast behind the stripping chains 4.5.
  • This conveyor could be replaced by a hopper or chute for resetting the refined ballast.
  • this machine avoids clogging of the usual screens and therefore the treatment of a larger volume of hourly ballast than existing screeners. Indeed, due to the presence of the purifier, it is possible to reduce the time spent by the stripped ballast on the screens for example by increasing the inclination of the latter.
  • the second screen 18 eliminating the earth and the elements of the ballast of a caliber less than the prescribed caliber is constituted by a conveyor-separator illustrated in FIGS. 3 to 5.
  • This conveyor-separator is formed by discs 22 provided at their periphery with notches, mounted on rotary shafts 23 driven in rotation, all in the same direction, using a motor 24.
  • Each disc has a toothed wheel 26 meshing with a chain 27 driven by the motor 24.
  • the discs 22 are staggered and this assembly forms the bottom of a container 25 leaving between the discs free spaces of a size corresponding to the elements of the ballast to be eliminated.
  • the elements of the ballast are introduced into the end A of the container 25 and are transported towards the end B of the latter by the rotation of the disks 22. In doing so, the elements of the ballast are crushed, turned over and shaken, which causes their separation and the elimination of most of the earth which surrounds them. All the elements of the ballast below the caliber and the earth can fall between the discs 22 and the shafts 23 on the conveyor 19 to be eliminated.
  • This washing system comprises pierced tubes 28 which are supplied with water by conduits 29 disposed above the container 25 and spray the elements of the ballast being in this container.
  • washing device can be associated with the purifier 20 in place of the convo separator. It is obvious that the machine can include two washing devices associated respectively with the conveyor-separator and the purifier.
  • the separator conveyor could consist of a vibrating conveyor, the conveyor belt of which would be formed by a trellis or by any other device subjecting the ballast to shocks or vibrations during its routing from one end to the other from the conveyor while letting the garbage escape.
  • first and second screens of the screening device are advantageously on one floor only, which simplifies the production thereof and further increases their hourly capacity and avoids clogging them.
  • the inclination of these screens can thus be different.
