Definitions

  • the invention relates to a machine for repairing a ballast bed moving by rolling on a railway track.
  • the invention relates to a method for repairing a ballast bed.
  • FR 2 539 156 describes a machine for repairing a ballast bed comprising a stripper comprising an excavating tool defining a direction of movement of the machine, a distributor for dividing an incoming ballast flow from the stripper into two outgoing ballast flows separated at least one front screening machine supplied by a first of the two outgoing ballast streams; and at least one rear screening machine supplied by the second of the two outgoing ballast streams.
  • the two screening machines are positioned side by side, behind the stripper in the direction of travel.
  • the front screening machine supplies clean ballast to a front discharge chute positioned in the immediate vicinity of the stripper.
  • the rear screening machine supplies clean ballast to a discharge chute positioned at the rear of the machine.
  • Conveyors transport the cuttings to one or more storage wagons, positioned at the very front of the repair machine, and in particular in front of the stripper and the associated rail lifting tools.
  • the resulting machine is no more compact than if it were provided with a single screening machine. It also requires a long transport path of the spoil to the extreme front of the vehicle supporting the repair machine. It also requires a large capacity conveyor to transport the ballast from the stripper to the screening machines.
  • the invention aims to remedy the drawbacks of the state of the art and to propose a compact and versatile machine, taking advantage of the available space and allowing a simplified flow of the ballast.
  • the distributor To prevent storage of the purified ballast coming from the front screening machine, provision is made for the distributor to include a variator to vary the ratio between the first and the second of the outgoing dissociated ballast flows.

  • the distributor is arranged between the rear screening machine and the front screening machine, preferably directly at the outlet of the stripper.
  • the distributor is thus located near the stripper, so that the distance to be traveled by the outgoing flow from the stripper before its division is minimized.
  • Subsequent delivery of the ballast to the front and rear screening machines requires only a reduced throughput relative to the outflow, which allows for a reduction in size of the transport paths to the screening machines.
