Definitions

  • the invention relates to a mobile ballast screening system intended for sorting soiled ballast and integrated into a mobile ballast bed repair system.
  • Mobile ballast bed repair systems are well known.
  • the principle of operation uses at least one excavation system to recover the soiled ballast by lifting or not the rails, and a conveyor assembly, which conveys the soiled ballast to at least one screen.
  • the screen has the effect of dividing the dirty ballast stream into a clean ballast stream and a discarded ballast stream.
  • the purified ballast flow is then preferably routed by a conveyor assembly to a track relining system, or failing that to a purified ballast storage container or wagon, while the discarded ballast flow is routed by a conveyor assembly. to a remote ballast storage container or wagon.
  • the document EP 0 408 837 describes a ballast repair machine comprising two excavation systems and two screens spaced apart from each other.
  • One of the screens is used to purify a superficial layer of track ballast, while the other screen is dedicated to the purification of a deeper layer of track ballast.
  • Each excavation system feeds a screen with an independent flow of soiled ballast.
  • Each screen produces a clean ballast stream and a stream of ballast ruled out.
  • the two streams of purified ballast are rerouted independently of each other towards the track, at two points of the machine far apart from each other.
  • the stream of ballast discarded from the screen furthest from the discarded ballast storage car is transported by a conveyor assembly to the nearest screen and directly joins the stream of ballast discarded from the nearest screen.
  • This arrangement makes it possible to collect the discarded ballast towards a single storage point and the use of the conveyor assembly for the ballast discarded by the flows of the two screens allows a simplification of the routing of the flows.
  • the machine is therefore not flexible in its use.
  • the document EP 0 240 648 describes a ballast repair machine comprising a single excavation system whose flow of soiled ballast feeds two screens in parallel.
  • the two screens are installed in such a way that the streams of purified ballast leaving each of the screens emerge at the same place and the resulting stream of purified ballast is routed by a conveyor assembly to the relining system.
  • the supply of soiled ballast to each of the screens requires a distribution of the flow of soiled ballast by a set of conveyors, each screen having its own conveyor.
  • the discarded ballast streams leaving the screens are collected by a conveyor assembly and the resulting discarded ballast stream is routed to the storage car.
  • the document WO2014080122A1 describes a ballast repair machine comprising an excavation system whose flow of soiled ballast feeds two screens in parallel.
  • the two screens are arranged end to end in such a way that their dirty ballast inlets are directly adjacent and that the flows of clean ballast at the outlet of each of the screens emerge at opposite ends of the two screens.
  • the discarded ballast is collected by a conveyor located directly below the two screens, which can convey the discarded ballast as required to either end of the work train. This conveyor must have a large capacity, since it collects the discarded ballast from the two screens.
  • the cleaned ballast is collected by a rerouting conveyor positioned below the discarded ballast conveyor.
  • the document EN 2539156 describes a ballast repair machine also comprising an excavation system and two screens.
  • the screens are arranged one after the other and a set of conveyors distributes the flow of soiled ballast between the two screens.
  • a set of conveyors collects the flows of ballast separated from the two screens, to convey it, in the opposite direction to that of the supply conveyors, towards a storage wagon. Clean ballast streams are routed to two separate discharge systems.
  • the arrangement of these two screens in the same direction makes it possible to simplify the feeding of the screens by the flow of soiled ballast, but does not provide for a single flow of purified ballast, so that the relining operation is complicated.
  • the invention aims to remedy the drawbacks of the state of the art and to make a mobile ballast screening system simpler and more flexible in its use.
  • the first discarded ballast outlet is located, with reference to the working direction, between the first clean ballast outlet and the second clean ballast outlet.
  • the zone of the mobile screening system in which there is a superposition, in the direction of work, of the rerouting and evacuation flows, is of short length, since it corresponds only to the zone where the first screen is located.
  • the first evacuation collection conveyor or conveyors are intended to convey only the discarded ballast coming from the first screen, and do not need to be dimensioned to convey the sum of the flows of discarded ballast corresponding to the two screens.
  • the flow of separated ballast conveyed in the overlap zone, under the first screen has a low flow rate compared to the total capacity of the system. It is therefore possible, if necessary, to minimize the motorization or the width of the first evacuation collection conveyor, which facilitates its installation in the limited space available under the first screen.
  • the part of the rerouting collection conveyor or conveyors located under the first screen to convey only the purified ballast coming from the second screen does not need to be sized to convey the sum of the flows of purified ballast corresponding to the two screens.
  • the flow of purified ballast conveyed in the covering zone, under the first screen has a low flow rate compared to the total capacity of the system. It is therefore possible, if necessary, to minimize the motorization or the width of a first rerouting collection conveyor of the set of one or more rerouting collection conveyors, if this facilitates its installation in the restricted space available under the first screen.
  • the set Redirection Conveyor System has a single conveyor, which is the redirection collection conveyor for both screens.
  • the second screen comprises a discarded ballast inlet able to be fed by the first evacuation collection conveyor or conveyors, and a weir for conveying the discarded ballast flow coming from the first screen from the discarded ballast inlet to to the second spread ballast output.
  • the second screen is configured to pass discarded ballast from the discarded ballast inlet to the discarded second ballast outlet, such that discarded ballast from the first screen and the second screen is collected by a second waste collection conveyor. outlet located directly below the second spread ballast outlet.
  • This second evacuation collection conveyor must have sufficient capacity to convey the sum of the flows of separated ballast generated by the two screens. It is therefore, where appropriate, of dimensions (particularly in width) greater than the first evacuation collection conveyor and/or of more powerful motorization.
  • the separated ballast inlet of the second screen is positioned above the second clean ballast outlet.
  • a particularly compact system is thus obtained.
  • the second screen and the first screen overlap.
  • the second clean ballast outlet can advantageously be arranged under the first screen, in particular under a part of the first screen comprising the first dirty ballast inlet, which makes it possible to reduce the distance between the dirty ballast inlets, the distance between the spread ballast outlets, and the distance between the clean ballast outlets.
  • the set of one or more rerouting conveyors comprises at least one common rerouting conveyor capable of conveying both the flow of purified ballast coming from the second outlet of purified ballast and the flow of ballast purified from the first purified ballast outlet, in the first direction, at least part of the common rerouting conveyor preferably being positioned under the first screen.
  • THE routes of the soiled, discarded and purified ballasts are consequently drastically simplified and, by the same token, the organization of the sets of rerouting and evacuation conveyors.
  • the rerouting conveyor may be one with the rerouting collection conveyor from the clean ballast outlet of the second screen, and extend below the first screen. Alternatively, it may be a separate conveyor, into which the rerouting collection conveyor from the clean ballast outlet of the second screen is able to discharge.
  • a simplification of flows is obtained thanks to the existence and orientation of the common rerouting conveyor.
  • the mobile ballast screening system includes a clean ballast relining or storage assembly fed by the set of one or more rerouting conveyors, the clean ballast relining or storage assembly being positioned preferably in front of the first dirty ballast inlet, and preferably in front of the first screen, in the first direction.

  • a common evacuation conveyor and by orienting it in the opposite direction to the rerouting conveyor, crossing of the sets of conveyors is avoided, hence an additional simplification of the system.
  • the mobile ballast screening system comprises an excavation assembly, and an assembly of one or more excavation conveyors, capable of transferring soiled ballast from the excavation assembly to the first distributor in constituting the incident oily ballast flow.
  • the first dirty ballast inlet is positioned between the excavation assembly and the second dirty ballast inlet, and in that, preferably, the first screen is positioned between the excavation assembly and the second dirty ballast inlet.
  • the conveyors of the various sets of conveyors can be of any type, continuous belt, chain or belt conveyor or any other material transport device, for example with buckets.
  • Screens can be of any type. They preferably use vibrating screens, and take advantage of gravity in the process of transferring the bulk elements of soiled ballast from the inlet to the clean ballast outlet, so that the clean ballast outlets and the clean ballast outlets discarded ballast are lower than the dirty ballast entries.
  • a second distributor interposed between the first distributor and the second dirty ballast inlet, capable in at least one mode of operation of the second distributor, of directing a flow of dirty ballast coming from the first distributor to the second inlet of soiled ballast and, in a second mode of operation of the second distributor, to direct the flow of soiled ballast coming from the first distributor towards a conveyor of the set of one or more discharge conveyors.
  • first distributor and the second distributor makes it possible to envisage different modes of operation, the two screens possibly being able to operate in parallel or alternately, depending on the positioning of the first screen, the second distributor making it possible to implement a mode of operation, in which all or part of the incident soiled ballast flow is directed by the first distributor towards the second distributor and by the latter towards an evacuation conveyor, without passing either through the first or through the second screen.
  • the mobile screening system may include a third screen having a third dirty ballast inlet and a third discarded ballast inlet, a third clean ballast outlet and a third discarded ballast outlet.
  • a third distributor is then interposed between the second distributor and the third dirty ballast inlet, able in at least one mode of operation, to direct a flow of dirty ballast towards the third dirty ballast inlet and, in another mode of operation, directing the flow of soiled ballast to a conveyor of the set of one or more evacuation conveyors. It is thus possible to increase the screening capacity of the system and to vary the number of operating modes, to adapt to the conditions of use.
