  • the sieve units, each with their own vibration drive, are inclined to the horizontal plane in such a way that they are seen transversely to the machine longitudinal direction, forming a common ballast receiving area, roof-shaped and with their end faces adjoining one another.
  • a conveyor belt arrangement which extends from the screening plant in the direction of the ballast discharge point located immediately behind the conveyor or clearing chain and transports the cleaned ballast in the working direction of the machine.
  • a ballast store with a floor surface serving as a conveyor belt and with side Ausläs- - sen arranged for ballasting the sleeper head portion at the forward work vehicle.
  • the overburden accumulated during cleaning is transported forward in the working direction via a overburden conveyor belt running through the conveyor or clearing chain to the front of the machine.
  • Such a known ballast bed cleaning machine has a relatively high output due to the relatively large screening plant with two independent screening units, but is not always problem-free with regard to the amount of ballast to be introduced on the roof-shaped screen in terms of an equal quantity distribution.
  • ballast bed cleaning machine for receiving, cleaning and reintroducing ballast ballast is also known.
  • This ballast bed cleaning machine is composed of a work vehicle with a chassis at the end and a work vehicle that is articulated with its front end to the first work vehicle and has a chassis arranged at the rear end.
  • a height-adjustable, endless conveyor or clearing chain is arranged on this rear work vehicle, the transverse run of which is carried out under the track.
  • a screening system which can be fed by the conveyor or clearing chain via a conveyor belt is arranged at the rear end of the front work vehicle and consists of two screening units arranged one behind the other in the machine longitudinal direction, inclined to the horizontal plane and arranged on the same level.
  • the output-side end of the front and higher sieving unit overlaps the input-side end of the rear sieving unit, so that there is only a cross section for the exit of the cleaned ballast of both sieving units.
  • a conveyor belt arrangement is provided for the reintroduction of the cleaned ballast, the rear, discharge-side end of which is located in the area of the conveyor or clearing chain above a chute-like distribution device. This has an outlet opening which leads directly to the track or formation and a further outlet opening which leads to a distribution conveyor belt and is provided in the region of the raised track.
  • ballast With this distribution conveyor belt, which can be swiveled transversely around its front end, the remaining ballast is transported in the opposite direction to the working direction and is distributed to both sides of the track that has already been worked on immediately before the last carriage of the cleaning machine.
  • a distribution element in the form of a pivotable and controllable flap is mounted in the distribution device. Depending on the position of the flap, part of the cleaned ballast can be dropped onto the track directly behind the conveyor or clearing chain and part via the distribution conveyor belt. When the machine is at a standstill, the entire ballast is diverted onto the distribution conveyor belt.
  • a spoil conveyor belt leading from the screening plant to the front end of the machine is provided for the removal of the spoil.
  • ballast bed cleaning machine The sieving capacity and the associated work capacity of such a known ballast bed cleaning machine is only slightly greater than comparable cleaning machines with a single sieving unit, since the entire ballast to be cleaned flows through both overlapping sieving units.
  • a relatively complex control device is required in order to no longer pass on at least part of the ballast coming from the screen.
  • Another part of the ballast transported on the conveyor belts is in any case transported at uneven heights into the ballast gap.
  • ballast bed cleaning machine for picking up, cleaning and reintroducing ballast ballast with a clearing device located on an upstream work vehicle and a screening plant located on a downstream work vehicle.
  • This is very complex and has eight sieve units, which are arranged in pairs in the transverse direction of the machine opposite one another in a V-shape.
  • the individual pairs of sieve units are arranged one behind the other in the machine longitudinal direction and each have an insertion point at the machine longitudinal edge for receiving the ballast from a deflection device for transport conveyor belt having lateral ballast discharge.
  • a conveyor belt arrangement for transporting the cleaned ballast to a discharge chute immediately upstream of the screening system is provided below the ballast ejection points located in the center.
  • Such a screening plant is structurally particularly complex and also prone to malfunction, the screening path of the individual screening units being very short due to the specified machine width and also not permitting high performance.
  • ballast bed cleaning machine for picking up, cleaning and reintroducing ballast ballast.
  • the screening plant immediately downstream of the conveyor or clearing chain has closing devices in the area of their ballast ejection point, each with a closure flap which can be actuated independently of a cylinder-piston arrangement. In this way e.g. If the cleaning machine suddenly comes to a standstill, the screening system can be used as a storage tank by closing the flaps and closing the ballast ejection points, thus avoiding any undesired accumulation of ballast.
  • the object of the present invention is now to provide a track-traveling ballast bed cleaning machine of the type described at the outset, with which higher performance can be achieved with better adaptation to the given track and ballast conditions.
  • ballast bed cleaning machine described at the outset in that the two sieve units of the sieving system which can be loaded over the transport conveyor belt form two separate ballast throw-in points and a common ballast discharge point on the machine frame located between these throw-in points. seen transversely to the machine longitudinal direction, V-shaped are arranged inclined to each other.
  • ballast flow rate is low, especially when the ballast hits the sieves, and therefore a ballast accumulation in this initial area can lead to a disadvantageous reduction in the sieving effect and performance. Due to the independence of the screening units from each other, depending on the amount of ballast accumulated, these can be used together with full output or one screening unit with full output and the other with half output, or even with smaller amounts of ballast one screening unit cannot be put into operation at all.
  • a particularly advantageous embodiment of the invention is characterized in that between the preferably concave or channel-shaped transport conveyor belt and the screening plant, a conveyor conveyor belt is preferably assigned to each screening unit, preferably also channel-shaped, for inserting the ballast to be cleaned, with one each Drive for one conveying direction opposite to the conveying direction of the ballast in the assigned sieve unit.

  • a preferred embodiment of the invention also consists in that the receiving end of each throw-in conveyor belt arranged above the respective sieving unit is arranged centrally between the two sieving units and above the two receiving ends the discharge end of the transport connected to the clearing or conveying chain. Conveyor belt is provided. With endless-throw-in conveyor belts arranged in this way, a shortened design of the transport conveyor belt and an equally long design or similar design of both throw-in conveyor belts is possible. This ensures that with the same length of transport of the ballast on both throw-in conveyor belts, the same delivery rate and impact of the ballast on the sieves can be achieved.
  • the invention is characterized thereby net that the transport conveyor belt is arranged up to both throw-in points of the two sieving units, with a deflection element for selectively dropping the ballast from the transport conveyor belt over the throw-in point of the one sieve unit closer to the conveyor or clearing chain and the dropping end of the Transport conveyor belt is arranged.
  • the deflecting elements can be used to deflect contaminated ballast, if required or optionally, from the transport conveyor belt onto the first sieving unit, in order to relieve the second sieving unit in the event of greater ballast accumulation. This means that both screening units can be fed directly and independently from the conveyor belt.
  • a temporary store is provided for the temporary storage of, in particular, excess ballast, which is arranged in the ballast flow between the screening plant and the discharge point of the further ballast transport arrangement.
  • a preferred embodiment of the invention consists in the fact that the intermediate storage as part of the conveyor belt arrangement for the further transport of the cleaned ballast is designed with a storage conveyor belt with storage side walls serving as a bottom surface and having its own drive.
  • an advantageous ballast storage can be carried out without retrofitting or adjustment work solely by the standstill of the storage conveyor belt serving as the floor area.
  • the invention is characterized in that at least one of the two sieve units which can be fed independently of one another is designed as an intermediate store with a control flap which is arranged in the region of the ballast ejection star and closes it.
  • this sieve unit which can be closed with a control flap, it can itself be used in the simplest way as an intermediate store for the ballast. It is particularly advantageous that by arranging two sieve units that can be used independently of one another, one sieve unit, e.g. can be used at full capacity, while the other sieving unit stores ballast and only passes it on when there is too little ballast.

  • the vibration drives can be connected to a control device which, when the drive for the conveyor or clearing chain is at a standstill, automatically reduces the oscillation frequency of one of the Both vibration drives are designed for a lower vibration frequency - the ballast no longer moving on the sieves.
  • This ensures that the ballast is stored in one of the two sieving units immediately when the machine's right of way is interrupted and the conveyor or clearing chain is stopped.
  • This storage is achieved in that the ballast on the sieves is not set in motion as a result of the lowering of the oscillation frequency of the vibration drive.

As soon as which starts the machine 1 moving forward, the storage conveyor belt 31 can, if appropriate, be put into operation again at an initially lower rotational speed. If, for example, there is less ballast with a low ballast bed height, the rotational speed of the conveyor belt 22 is increased by applying more force to the hydraulic drive 46.

  • the rear sieve unit 20 and the associated throw-in conveyor belt 26 can be taken out of operation in order to save energy. If the rotational speed of the conveyor belt 22 is not increased so much, different variants are possible. For example, the larger proportion of ballast can be thrown onto the front and the remaining part onto the rear throw-in conveyor belt 26.
  • the oscillation frequency of the rear sieve unit 20 is also expediently reduced.
  • All conveyor belts are formed as endless belts made of fabric-reinforced rubber, avoiding malfunctions to achieve high transport performance, which are guided in a cross-sectionally channel-shaped or concavely curved bed made of rollers that can be rotated transversely to the transport direction. This ensures that even with particularly long transport routes, no ballast or overburden falls sideways from the conveyor belt onto machine parts or work units.
