Definitions

  • the invention relates to a mobile system for cleaning the ballast bedding of a track, with a conveyor and clearing chain arranged on a first work vehicle between its two running gears in the area of a track lifting device, provided for ballast pick-up and a conveyor chain which can be loaded by the latter via a transport conveyor belt and on a second one Upstream work vehicle arranged screening plant with overburden conveyor belt, as well as with a ballast distribution device with conveyor belts for transporting and reintroducing the cleaned ballast up to a first ballast outlet provided directly behind the ballast excavation point - for a first ballast layer on the cleared track bed and / or via a distribution conveyor belt up to one in the working direction downstream second ballast outlet - for applying a second ballast layer to the first ballast layer.
  • CH-PS 651 87o a mobile system for cleaning the ballast bed of a track of the type described above, wherein a conveyor and clearing chain provided for ballast pick-up is arranged on a first work vehicle between its two trolleys in the area of a track-laying device.
  • a screening plant which is located on a second, upstream, working vehicle and is coupled with this, is formed from two screens with overburden conveyor belt via a conveyor belt with ballast to be cleaned.

  • the cleaned ballast is dropped directly behind the ballast excavation point via a distributor device in a first ballast outlet to form a first ballast layer on the cleared track bed.
  • a distribution conveyor belt is arranged, the discharge end of which is designed as a second ballast outlet - for applying a second layer of ballast to the first ballast layer in the area of the intermediate compartments of the sleepers, which may be slightly raised.
  • a distributor member is pivotally mounted, through which a predeterminable portion of the cleaned ballast can be distributed to the first ballast outlet and the rest of the ballast can be distributed to the second ballast outlet via the distribution conveyor belt.
  • the disadvantage of this plant is that the cleaned ballast that accumulates in varying amounts due to the often very different accumulation of overburden components either inevitably leads to an unevenly high or low second ballast layer; or all of the remaining cleaned ballast is thrown off over the second ballast outlet or completely dropped aside over the flank areas via the pivotable distribution conveyor belts.
  • the second ballast outlet is still in the track area lifted by the same device from the target level, albeit slightly - depending on the lifting dimension - so that ballast still exists between the threshold and the first layer of ballast in an uncontrolled manner and the track at an irregular altitude can spend. Irregular ballast accumulations or ballast gaps cannot always be avoided as a result, which cannot be improved even by the downstream ballast leveling device.
  • a mobile installation for cleaning the ballast bedding of a track with subsequent compaction of the ballast bedding is known.
  • This system consists of a first work vehicle designed as a ballast bed cleaning machine with a conveyor and clearing chain and a screening plant with conveyor belts and a second work vehicle following this, which is designed as a ballast compacting machine with a ballast-threshold intermediate compacting unit and this lifting and straightening unit arranged upstream in the working direction .

  • a second ballast outlet which can be fed via conveyor belts, is located directly behind the front chassis of the second subordinate work vehicle and is designed as ballast storage with controllable outlet openings.
  • the cleaned ballast is transported from the screening plant provided on the first work vehicle via a ballast distribution device with conveyor belts to the second ballast outlet.
  • only one ballast outlet is provided on the first work vehicle.
  • the second work vehicle has pairs of expanding stuffing tools designed as a push-thrust-deep compacting tool, which also serve to compress the intermediate sleeper compartments. In order to achieve a reasonably good distribution of ballast, complex middle and side plows - without track lifting devices - are connected upstream of the compacting unit.
  • the first working vehicle which is at the rear in the working direction, is designed as a ballast bed cleaning machine with a conveyor and clearing chain provided for ballast pick-up, a track lifting device provided in its area and a screening system that can be fed by the conveyor and clearing chain.

  • Such a system can also be used to clean a ballast bed with a relatively low height, without the track having to be subjected to an excessive bend for the passage of the conveyor and clearing chain in an inadmissible manner, in that the entire track in front of the first working vehicle is also tamped by the tamping machine is only stuffed up at every second or third threshold.
  • a ballast leveling or compacting device is also provided in the area behind the ballast outlet.
  • a mobile system for cleaning the ballast bedding of a track consists of a first work vehicle with a conveyor and clearing chain arranged between its two undercarriages, intended for ballast pick-up, and a screening plant which can be fed by a conveyor belt and arranged on a second downstream work vehicle with a spoil conveyor.
  • a ballast distribution device For transporting and reintroducing the cleaned ballast to a first ballast outlet provided directly behind the ballast excavation point and a second ballast outlet arranged directly in front of the rear chassis of the first work vehicle, a ballast distribution device with a plurality of conveyor belts arranged one behind the other is provided.
  • the first ballast outlet is intended for a first ballast layer on the cleared track bed and the second ballast outlet for applying a second ballast layer to the first ballast layer in the area of the intermediate threshold compartments before any load from undercarriages.
  • the screening plant is formed from two screening units which are independent of one another and form an inverted V, have a common ballast chute and separate ballast chute discharge points.
  • the ballast distribution device is provided between the screening plant and the two ballast outlets on the first work vehicle, an intermediate store being arranged on a conveyor belt at the rear end for intermediate storage of cleaned ballast. In this system, too, the ballast is discharged only before the track structure is loaded.
  • the object of the invention is to provide a mobile system of the type described in the introduction, from which it is assumed that an improved and more precise or denser distribution of the resulting, cleaned ballast can be achieved in order to be sufficiently uniform afterwards or in the same work to create the ballast accumulations required for a subsequent tamping process in the right place, so that in the following the track can be driven at a relatively high speed with stuffed sleepers.
  • the ballast distribution device for simultaneous or optional discharge of the cleaned ballast over the first and / or the second ballast outlet for the continuous formation of the first ballast layer and / or the second ballast layer and / or Forwarding of excess ballast is designed with a deflection element that can be acted upon by a drive, with a transport conveyor belt connected to the second ballast outlet with its end on the receiving side, with another deflection element, for the removal of the excess ballast, and the second one - with the discharge end of optionally with cleaned ballast feedable distribution conveyor formed ballast outlet is arranged behind the rear chassis of the first work vehicle.
  • Such a system with a ballast distribution device for the simultaneous or optional discharge of the cleaned ballast into a first and a second ballast outlet and for the transfer of excess ballast, e.g. to a subsequent loading wagon, regardless of the fluctuating accumulation of cleaned ballast, enables the creation of a uniform first layer of ballast and an equally uniform layer of ballast between the sleepers.
  • the pressure load on the undercarriage on the rail structure formed by the sleepers and rails ensures that it is fully supported on the first ballast layer before the sleeper compartments are ballasted through the second ballast outlet.
  • this system can therefore be used to create a really uniform and optional height of the first ballast layer with a correspondingly uniform height and the second ballast layer in the intermediate sleeper compartments, depending on the resulting ballast volume of the track, before the tamping .
  • a constantly precise track height position and a uniform track ballast can be created as a particularly advantageous prerequisite for a subsequent uniform tamping of the sleeper supports.
  • this tamping can be carried out independently of the system in a short time interval or also by a tamping machine connected to the system in a single operation.
  • An advantageous embodiment of the invention is characterized in that the second ballast outlet is formed by the dropping end of at least one endless, preferably trough-shaped distribution conveyor belt, which projects to the rear undercarriage of the first work vehicle or extends cantilevered above it.
  • the displaceable mounting of the endless distribution conveyor belt creates the possibility in a structurally particularly simple way, if necessary, the second ballast outlet in the working direction to the rear. eg with a connected tamping machine directly in front of the work units.
  • a projecting position of the discharge end can be reached with the displaceable mounting, so that the second ballast outlet can be formed directly behind the chassis of the first work vehicle.
  • the second ballast outlet can be formed by the shedding end of at least one endless, preferably gutter-shaped distribution conveyor belt that extends to the rear undercarriage of the first work vehicle or is also cantilevered.
  • a ballast outlet can be modified in a simple manner, for example by arranging chutes or redirecting elements, as a result of which the ballast can be concentrated in a targeted manner on the sleeper support areas located on both sides of a rail track. This solution, which is simple in construction, can also be easily implemented in known ballast bed cleaning machines.
  • a particularly advantageous embodiment of the invention is characterized in that the second ballast outlet behind the rear undercarriage of the first work vehicle up to immediately behind a front undercarriage of a downstream third - with a ballast accumulator and via an adjustment drive to this track pot lifting and relocating Straightening unit from permitted - work vehicle is provided and is formed by controllable outlet openings with outlet chutes of the ballast store that can be fed by one of the preferably trough-shaped distribution conveyor belts.
  • ballast outlet as ballast storage with controllable outlet openings, regardless of the amount of ballast accumulating irregularly from the screening plant, creates the possibility of continuously uniform ballast discharge.
  • the ballast still occurring in the event of a sudden stop of the plant due to the wake of the screening plant and the ballast distribution device can be temporarily stored, avoiding disadvantageous ballast accumulations.
  • sections with a particularly large amount of overburden and a small proportion of ballast can be bridged by throwing off ballast stored in these sections in order to maintain a uniform second layer of ballast.
  • the ballast bed can be cleaned in one operation with a complete and uniform track ballast, together with the immediate creation of evenly stuffed sleeper supports for a permanent, accurate track position.
  • the invention is characterized in that in each case two first and second ballast outlets arranged adjacent to the longitudinal direction of the track and approximately above the two rail tracks - to form two ballast layers running continuously in the longitudinal direction of the track and parallel to one another or to create the ballast layers in the individual threshold intermediate compartments of the crossing points rails / threshold of both rail tracks - are provided.
  • first two ballast outlets that run transversely to the machine longitudinal direction, a targeted division of the ballast into the area of the sleepers running under the rails as two continuously parallel ballast banks is possible in an economical manner.
  • a compacting device preferably formed by a compacting bar formed by drives that can be displaced by striking movements, is arranged on the first working vehicle in the area of the first ballast outlet, in particular immediately in front of the accumulated amount of ballast - to compact the introduced first ballast layer against the working direction.
  • the sleeper support area which is decisive for a permanent track position, is subjected to a pre-compression immediately after the ballast has been thrown, which is further reinforced by the pressure of the following undercarriage or another undercarriage located in front of the second ballast outlet.
  • the screen system formed by the screen units arranged approximately in the center of the second upstream work vehicle and preferably loaded by two independent individual conveyor belts and which can be fed by the preferably gutter-shaped transport conveyor belt, - cleaned ballast accumulated over a buffer storage device and via one Endless, independently actuated drive belt can be fed, at least partially, optionally via a control device and the ballast distribution device to the first and / or third work vehicle to the first or second ballast outlet for ballast reintroduction or for further transport of excess ballast.
  • the ballast storage can be fed evenly to both ballast outlets - regardless of the fluctuating amounts of cleaned ballast - for the formation of consistently high ballast layers.
  • the intermediate store is also of particular advantage in that the use of two completely independent sieve units results in a particularly high sieving capacity with two outlet cross-sections which are separate from one another but bring together.
  • the control device can additionally control the ballast distribution device with the deflection elements in such a way that, with a corresponding change, only the excess ballast quantities transported beyond the second ballast outlet are constantly and uniformly available for both ballast outlets.

  • Transport conveyor belts are arranged with the interposition of the deflecting element for the further transport of excess ballast.
  • the arrangement of the deflecting element above the ballast storage means that the ballast flow can be easily and optionally diverted into the ballast storage and / or onto the transport conveyor belt for the removal of excess ballast, with appropriate pivoting. This enables a particularly rapid adaptation to different ballast conditions and excess ballast does not have to be thrown off to the side, which is often the case in station areas, is not possible at all.

Immediately in the working direction, there is then further compaction by the rear undercarriage 33 of the first work vehicle 5 resting on the track structure.
  • the ballast thrown behind the deflection element 3o can be transported through the distribution conveyor belts 32 against the working direction onto the following third work vehicle 8 and in the region of the discharge end 31, depending on the position of the deflection element 5 0 , in the ones below Ballast storage 49 and / or are thrown onto the subsequent conveyor belt 51.
  • the ballast located in the ballast reservoir 49 arrives in the second ballast outlet 25 to form a second ballast layer 28 in the intermediate sleeper compartments 27 of the track 4, which emerge from the outlet openings 48 tendency amounts of ballast are controlled by the worker located in the operating cabin 57 depending on the need for the subsequent tamping process.
  • ballast transport loading train 52 Following the system 1.
  • the track 4 newly ballasted by the first ballast layer 26 and the second ballast layer 28, is tamped in one operation by the track pot and lifting / leveling unit 53, 54 cyclically using the adjustment drive 55 is moved from one to the next threshold 2.
  • Any ballast lying on the sleepers after the tamping process is picked up by the sweeping device 58 located at the rear end of the system 1 and conveyed onto the ballast bed flank with the aid of the cross conveyor belt.
  • the hold-down device 46 located directly in front of the compacting device 41 also prevents the track 4 from being raised in an uncontrolled manner by the compacting forces of the compacting device 41.
  • the height control of this hold-down device 46 like the control of the ballast discharge in the area of the first ballast outlet 22, is carried out by the worker located in the operating cabin 43 via the central control device 37.
  • the control of the deflecting element 5o takes place as a function of the filling state of the ballast store 49 located underneath. As soon as this is full, the deflecting element 5o is pivoted forward with its free end below the discharge end 31 (FIG. 3), so that the whole of the distribution conveyor belt 32 transported ballast as excess ballast is dropped onto the conveyor belt 51 and for loading on the ballast transport loading train 52.
  • the deflection element 5o is pivoted somewhat backwards, so that a part of the cleaned ballast is in turn conveyed to the ballast store 49 and, in the case of larger amounts of ballast, a part is carried on as excess ballast. If smaller amounts of ballast are obtained, the deflection element 5o is pivoted so far back that the entire ballast transported on the distribution conveyor belt 32 is deflected into the ballast store 49.
