Description

Die Erfindung betrifft eine Maschine zur Bearbeitung der Schotterbettung eines Gleises, mit einem auf Schienenfahrwerken abgestützten Maschinenrahmen, einer Ansaugeinheit mit einem eine Saugöffnung zum Absaugen von Schotter aufweisenden, höhen- und seitenverstellbaren Saugrüssel und einer der Ansaugeinheit zugeordneten Förderbandanordnung für den Abtransport des angesaugten Schotters, einer dem Saugrüssel in Arbeitsrichtung nachgeordneten und einen Einwurftrichter aufweisenden Schotterabwurfeinrichtung sowie einem Gleishebeaggregat.The invention relates to a machine for processing the ballast bedding of a track, with a machine frame supported on rail bogies, a suction unit with a suction nozzle for suctioning ballast, height and side adjustable suction nozzle and a conveyor belt arrangement assigned to the suction unit for the removal of the suctioned ballast, one downstream of the suction proboscis in the working direction and a ballast discharge device and a track lifting unit.

Eine derartige Maschine ist bereits aus der WO 94/17245 bekannt und dient zum Absaugen bzw. Austauschen der kompletten Schotterbettung eines Gleises. Der unter Mithilfe von Räumorganen aus dem Bereich unterhalb der Schwellen entfernte Schotter gelangt über den Saugrüssel in einen am Maschinenrahmen befestigten Schotterspeicher, dessen Auslaßöffnung einer Förderbandanordnung zugeordnet ist. Von dieser wird der abgesaugte Bettungsschotter zum in Arbeitsrichtung vorderen Maschinenende transportiert und in an die Maschine gekuppelte Silowagen verladen. Gleichzeitig erfolgt vom hinteren Ende der Maschine her das Einbringen von Neuschotter, der aus Silowagen über den Einwurftrichter einer Schotterabwurfeinrichtung in Arbeitsrichtung unmittelbar hinter den Räumorganen ins Gleis abgeworfen wird. Das Gleis wird dabei im Abwurfbereich mittels des Hebeaggregates höhenmäßig in seiner Position gehalten. Eine Wiederverwendung des Altschotters (zur Gänze oder auch nur zum Teil) ist nicht vorgesehen.Such a machine is already known from WO 94/17245 and is used to vacuum or replace the complete ballast bedding of a track. The ballast, which is removed from the area below the sleepers with the help of clearing elements, passes through the suction nozzle into a ballast store attached to the machine frame, the outlet opening of which is assigned to a conveyor belt arrangement. From there, the extracted ballast ballast is transported to the front end of the machine in the working direction and loaded into silo wagons coupled to the machine. At the same time, new ballast is introduced from the rear end of the machine, which is dropped from silo wagons into the working direction directly behind the clearing elements via the throw-in funnel of a ballast discharge device. The height of the track is held in position in the discharge area by means of the lifting unit. A reuse of the old ballast (in whole or in part) is not intended.

Gemäß DE 41 01 432 A1 ist auch eine Maschine zur Durchführung einer Gleisabsenkung bekannt. Am in Arbeitsrichtung vorderen Ende des auf Laufwerken gleisverfahrbaren Maschinenrahmens befindet sich eine Gleishebevorrichtung sowie eine höhenverstellbare Anordnung zum Absaugen des Schotters aus dem Gleis bis auf ein gewünschtes, durch ein Räum- bzw. Planierorgan geschaffenes Niveau. Der Schotter gelangt über ein Förderband zu einem am hinteren Maschinenende positionierten Fülltrichter. In diesem befindet sich ein Sieb zum Reinigen des Schotters sowie ein Förderband zum Abtransport des ausgesiebten Abraumes. Der Gleisrost legt sich im Bereich des hinteren Laufwerkes von selbst auf das neue, niedrigere Schotterbettniveau und wird nun, je nach Bedarf, mit gereinigtem Schotter aus dem Fülltrichter zwischen den Schwellen verfüllt. In einem abschließenden Arbeitsschritt wird das Gleis später unterstopft.According to DE 41 01 432 A1, a machine for performing a track lowering is also known. At the front end of the machine frame, which can be moved on tracks, there is a track lifting device and a height-adjustable arrangement for extracting the ballast from the track to a desired level created by a clearing or leveling element. The ballast is transported via a conveyor belt to a filling funnel positioned at the rear end of the machine. In this there is a sieve for cleaning the ballast and a conveyor belt for removing the sifted overburden. In the area of the rear drive, the track grate automatically lays on the new, lower ballast bed level and is now filled with cleaned ballast from the hopper between the sleepers, as required. In a final step, the track will be stuffed later.

Die Aufgabe der vorliegenden Erfindung besteht nun in der Schaffung einer Maschine der eingangs genannten Art, die unter Beibehaltung der bekannten Vorteile auch zur Sanierung von unterhalb der Schotterbettung befindlichen Planumsabschnitten einsetzbar ist.The object of the present invention is now to provide a machine of the type mentioned at the outset which, while maintaining the known advantages, can also be used for the rehabilitation of subgrade sections located below the ballast bed.

Diese Aufgabe wird mit einer gattungsgemäßen Maschine gelöst, die durch eine in Maschinenlängsrichtung verlaufende Fördereinrichtung gekennzeichnet ist, die ein der Ansaugeinheit zugeordnetes Aufnahmeende und ein dem Einwurftrichter der Schotterabwurfeinrichtung zugeordnetes Abwurfende aufweist, wobei das Gleishebeaggregat zwischen Saugöffnung und Schotterabwurfeinrichtung angeordnet ist.This object is achieved with a machine of the generic type, which is characterized by a conveyor device running in the machine longitudinal direction, which has a receiving end assigned to the suction unit and a discharge end assigned to the insertion funnel of the ballast discharge device, the track lifting unit being arranged between the suction opening and the ballast discharge device.

Mit einer derartig ausgebildeten Maschine ist unter lediglich geringem konstruktiven Mehraufwand ein relativ langer schotterfreier Gleisbereich zur Sanierung von Planumsabschnitten herstellbar. Dabei ist von Vorteil, daß für den vom Gleis kurzfristig entfernten Schotter keine zeit- und arbeitsaufwendige Zwischenspeicherung in einem der Maschine angeschlossenen Speicherwagen erforderlich ist. Der gesamte Schotter ist praktisch in dem durch Ansaugeinheit, Fördereinrichtung und Einwurftrichter gebildeten Kreislauf zwischenspeicherbar. Infolge der speziellen Ausbildung der Maschine kann in besonders vorteilhafter Weise sofort im Anschluß an den Schotteraushub die Bearbeitung des freigelegten Planums erfolgen und als Abschluß des Maschineneinsatzes das sanierte Planum sofort wiederum mit Schotter bedeckt werden, ohne daß es dazu gesonderter Maschinenbewegungen bedarf. Damit sind die für die Sanierung erforderlichen Sperrzeiten des Gleises unter Reduktion des Maschinen-bzw. Fahrzeugaufwandes deutlich verringerbar.With a machine designed in this way, a relatively long ballast-free track area for the rehabilitation of formation sections can be produced with only little additional design effort. The advantage here is that no time-consuming and labor-intensive intermediate storage in a storage car connected to the machine is required for the ballast removed from the track at short notice. The entire ballast can be practically buffered in the circuit formed by the suction unit, conveyor and hopper. As a result of the special design of the machine, the uncovered formation can be processed in a particularly advantageous manner immediately after the excavation of the ballast and, as a conclusion of the use of the machine, the rehabilitated formation can again be covered with ballast without the need for separate machine movements. This means that the closing times of the track required for the renovation are reduced while reducing the machine or. Vehicle expenses can be significantly reduced.

Weitere durch die Erfindung geschaffene Vorteile ergeben sich aus den Unteransprüchen bzw. aus der Beschreibung.Further advantages created by the invention result from the subclaims or from the description.

Im folgenden wird die Erfindung anhand einer Zeichnung näher beschrieben, wobei
   Fig. 1 und 2 eine aus Platzgründen in zwei Teilen dargestellte Seitenansicht der Maschine zeigen.In the following the invention is described in more detail with reference to a drawing, wherein
1 and 2 show a side view of the machine shown in two parts for reasons of space.

In Fig. 1 und 2 ist eine Maschine 1 zur Bearbeitung der Schotterbettung 2 eines Gleises 3 zu sehen, wobei der - bezüglich einer durch einen Pfeil 4 angedeuteten Arbeitsrichtung - hintere Abschnitt der Maschine 1 in Fig. 1 und der vordere Abschnitt in Fig. 2 wiedergegeben ist. Die Maschine 1 weist einen langgestreckten Maschinenrahmen 5 auf, der sich in einen vorderen Rahmenteil 6 und einen hinteren, gekröpft ausgebildeten Rahmenteil 7 gliedert. Die beiden Rahmenteile 6 und 7 sind über ein Gelenk 8 allseits beweglich miteinander verbunden und über insgesamt drei Schienenfahrwerke 9 an den beiden Längsenden des Maschinenrahmens 5 sowie im Bereich des Gelenkes 8 auf dem Gleis 3 abgestützt. An den beiden Längsenden sind weiters jeweils eine Fahrkabine 10 sowie eine Pufferkupplung 11 zur Verbindung mit weiteren Gleisbaufahrzeugen vorgesehen. Ein Motor 12 dient der Energieversorgung eines Fahrantriebes 13 sowie der weiteren - noch zu beschreibenden - Antriebe und Aggregate der Maschine 1.1 and 2 show a machine 1 for processing the ballast bed 2 of a track 3, the rear section of the machine 1 in FIG. 1 and the front section in FIG. 2 with respect to a working direction indicated by an arrow 4 is reproduced. The machine 1 has an elongated machine frame 5, which is divided into a front frame part 6 and a rear, cranked frame part 7. The two frame parts 6 and 7 are movably connected to one another via a joint 8 and are supported by a total of three rail bogies 9 on the two longitudinal ends of the machine frame 5 and in the region of the joint 8 on the track 3. At the two longitudinal ends there are also a driving cabin 10 and a buffer coupling 11 for connection to other track construction vehicles. A motor 12 is used to supply energy to a travel drive 13 and to the further drives and units of the machine 1, which will be described later.

Am vorderen Rahmenteil 6 befindet sich eine Ansaugeinheit 14, die sich aus einem Unterdruckerzeuger 15, einer Filterkammer 16, einem Schotterspeicher 17 und zwei in diesen mündenden Saugschläuchen 18 zusammensetzt. Das freie Ende eines jeden dieser in Maschinenquerrichtung distanziert und etwa parallel zueinander verlaufenden Saugschläuche 18 ist mit einem Saugrüssel 19 verbunden, der jeweils eine Saugöffnung 20 zum Absaugen von Schotter aufweist. Jeder Saugrüssel 19 ist anhand einer Führung 21 über Antriebe 22 höhen- und seitenverstellbar im gekröpften Bereich des hinteren Rahmenteiles 7 an diesem befestigt.On the front frame part 6 there is a suction unit 14, which is composed of a vacuum generator 15, a filter chamber 16, a ballast accumulator 17 and two suction hoses 18 opening into these. The free end of each of these suction hoses 18, which is spaced apart in the cross-machine direction and runs approximately parallel to one another, is connected to a suction nozzle 19, each of which has a suction opening 20 for the suction of ballast. Each proboscis 19 is attached to the rear frame part 7 by means of a guide 21 which is adjustable in height and in the side in the cranked region of the rear frame part 7.

Eine Förderbandanordnung 23 erstreckt sich in Maschinenlängsrichtung unterhalb der Filterkammer 16 und des Schotterspeichers 17 und weist einen am vorderen Maschinenende erhöht angeordneten Abschnitt 24 auf. Diesem ist ein längsverschiebbar am Maschinenrahmen 5 bzw. am Rahmenteil 6 gelagertes Ladeförderband 25 zugeordnet, das während der Überstellfahrt der Maschine 1 in eine nicht-vorkragende Ruhestellung eingefahren werden kann. Das bezüglich der Maschinenlängsrichtung gegenüberliegende, hintere Ende der Förderbandanordnung 23 weist ein erhöht angeordnetes Abwurfende 26 auf, das über das Gelenk 8 bis über den hinteren Rahmenteil 7 vorkragend angeordnet ist.A conveyor belt arrangement 23 extends in the machine longitudinal direction below the filter chamber 16 and the ballast store 17 and has a section 24 arranged at the front end of the machine. This is associated with a longitudinally displaceable loading conveyor belt 25 mounted on the machine frame 5 or on the frame part 6, which can be moved into a non-projecting rest position during the transfer travel of the machine 1. The rear end of the conveyor belt arrangement 23 opposite the longitudinal direction of the machine has an elevated discharge end 26 which is arranged so that it projects beyond the joint 8 to beyond the rear frame part 7.

Sowohl der Schotterspeicher 17 als auch die Filterkammer 16 sind an ihren Unterseiten mit Entladeöffnungen 27 versehen, die sich unmittelbar oberhalb der Förderbandanordnung 23 befinden und jeweils über eine fernbedienbare Klappe 28 verschließbar sind. Die Förderbandanordnung 23 ist mit einem Rotationsantrieb 29 ausgestattet, der zur wahlweisen Beaufschlagung bzw. Rotation in beiden Drehrichtungen ausgebildet ist.Both the ballast store 17 and the filter chamber 16 are provided on their undersides with discharge openings 27, which are located directly above the conveyor belt arrangement 23 and can each be closed by a remotely operated flap 28. The conveyor belt arrangement 23 is equipped with a rotary drive 29, which is designed for optional loading or rotation in both directions of rotation.

In Arbeitsrichtung unmittelbar vor dem hintersten Schienenfahrwerk 9 der Maschine 1 ist am hinteren Rahmenteil 7 eine als Schottersilo ausgebildete Schotterabwurfeinrichtung 30 befestigt, die einen oben offenen Einwurftrichter 31 und unmittelbar oberhalb des Gleises befindliche Entladeschurren 32 aufweist. Diesen ist ein höhenverstellbarer und über einen Antrieb 36 um eine in Maschinenquerrichtung verlaufende horizontale Achse 37 verschwenkbarer Verdichtbalken 38 unmittelbar vorgeordnet. Eine einen Antrieb 46 aufweisende Fördereinrichtung 33 erstreckt sich entlang des gekröpften Bereiches des Rahmenteiles 7 und ist an dessen Oberseite montiert, wobei ein Aufnahmeende 34 der Fördereinrichtung 33 dem Abwurfende 26 der Förderbandanordnung 23 zugeordnet ist. Ein Abwurfende 35 der Fördereinrichtung 33 ist über dem Einwurftrichter 31 positioniert.In the working direction directly in front of the rearmost rail running gear 9 of the machine 1, a ballast discharge device 30 designed as a ballast silo is fastened to the rear frame part 7, which has an opening hopper 31 open at the top and unloading chutes 32 located directly above the track. This is preceded by a height-adjustable compression bar 38 which can be pivoted via a drive 36 about a horizontal axis 37 running in the transverse direction of the machine. A conveyor device 33 having a drive 46 extends along the cranked region of the frame part 7 and is mounted on its upper side, a receiving end 34 of the conveyor device 33 being assigned to the discharge end 26 of the conveyor belt arrangement 23. A discharge end 35 of the conveyor 33 is positioned above the insertion funnel 31.

Im gekröpften Bereich des Rahmenteiles 7 zwischen den Saugöffnungen 20 der Saugrüssel 19 und den in Maschinenlängsrichtung von diesen distanzierten Entladeschurren 32 der Schotterabwurfeinrichtung 30 befindet sich eine Arbeitsstelle 40, innerhalb der ein Erdplanum 47 freigelegt ist. Ein in diesem Bereich zwischen Saugöffnung 20 und Schotterabwurfeinrichtung 30 angeordnetes, anhand von Antrieben 41 höhenverstellbar mit dem Maschinenrahmen 5 bzw. dem Rahmenteil 7 verbundenes Gleishebeaggregat 39 ist sowohl von den Saugöffnungen 20 als auch von den Entladeschurren 32 distanziert. Der Arbeitsstelle 40 ist außerdem eine Arbeitskabine 42 zugeordnet, die zwischen den Saugrüsseln 19 und dem mittleren Schienenfahrwerk 9 mit dem Maschinenrahmen 5 verbunden ist und in der sich eine zentrale Steuereinrichtung 48 befindet.In the cranked area of the frame part 7 between the suction openings 20 of the suction nozzle 19 and the discharge chutes 32 of the ballast discharge device 30 which are distant from them in the machine longitudinal direction, there is one Work station 40, within which an earth level 47 is exposed. A track lifting unit 39 arranged in this area between the suction opening 20 and ballast discharge device 30 and connected to the machine frame 5 or the frame part 7 in a height-adjustable manner by means of drives 41 is distanced both from the suction openings 20 and from the unloading chutes 32. The work station 40 is also assigned a work cabin 42, which is connected to the machine frame 5 between the suction probes 19 and the central rail running gear 9 and in which a central control device 48 is located.

Der Arbeitseinsatz der Maschine 1 beginnt damit, daß durch Absenken der beiden Saugrüssel 19 kontinuierlich Schotter abgesaugt wird, um dadurch unter Schaffung einer Arbeitsstelle 40 ein Erdplanum 47 zu dessen Bearbeitung freizulegen. Dabei wird das freischwebende Gleis 3 durch das Gleishebeaggregat 39 in der ursprünglichen Lage gehalten. Sobald das Erdplanum 47 zwischen den beiden Saugrüsseln 19 und dem Verdichtbalken 38 freigelegt ist, kann beispielsweise unter örtlichem Stillstand der Maschine 1 eine Bearbeitung des Erdplanums 47 beginnen. Anstelle des Erdplanums kann natürlich auch ein festes Bauwerk, z.B. eine Brücke, zur Bearbeitung freigelegt werden. Nach Beendigung der Sanierungsarbeiten werden die beiden Saugrüssel 19 unter Anheben außer Betrieb gesetzt und bei kontinuierlicher Maschinenvorfahrt die Wiedereinbringung des Schotters unter entsprechender Öffnung der Entladeschurren 32 gestartet. Die Steuerung der Antriebe 45 der Entladeschurren 32 kann in vorteilhafter Weise durch eine in der hinteren Fahrkabine 10 befindliche Bedienungsperson durchgeführt werden. Parallel dazu erfolgt durch eine in Maschinenlängsrichtung verlaufende, hinund hergehende Bewegung des Verdichtbalkens 38 eine Verdichtung des abgeworfenen Schotters.The work of the machine 1 begins with the fact that ballast is continuously sucked off by lowering the two proboscis 19, thereby uncovering an earth sub-level 47 for processing, thereby creating a job 40. The free-floating track 3 is held in the original position by the track lifting unit 39. As soon as the earth level 47 between the two proboscis 19 and the compression bar 38 is exposed, processing of the earth level 47 can begin, for example, while the machine 1 is stationary. Instead of the earth level, a solid structure, e.g. a bridge to be exposed for editing. After the renovation work has been completed, the two proboscis 19 are put out of operation by lifting and, with continuous machine advance, the ballast is reintroduced by opening the discharge chutes 32 accordingly. The control of the drives 45 of the unloading chutes 32 can advantageously be carried out by an operator located in the rear cab 10. Parallel to this, a compression of the thrown gravel is carried out by a reciprocating movement of the compression bar 38 in the longitudinal direction of the machine.

Abweichend von der beschriebenen Einsatzweise besteht natürlich auch die Möglichkeit, die Arbeitsstelle 40 mit der kontinuierlichen Arbeitsvorfahrt der Maschine 1 mitwandern zu lassen, d.h. daß kontinuierlich der vordere Bereich der Arbeitsstelle 40 abgesaugt wird, während in deren hinterem Endbereich kontinuierlich Schotter abgeworfen und verdichtet wird.Deviating from the described mode of use, there is of course also the possibility of having the work station 40 move with the continuous work approach of the machine 1, ie that the front region of the work station 40 is continuously suctioned off, while gravel is continuously thrown off and compacted in the rear end region thereof.

Sollte der abgesaugte Schotter sehr stark verschmutzt und damit nicht mehr wiederverwendbar sein, kann dieser unter Abwurf auf die Förderbandanordnung 23 über das Ladeförderband 25 einem vorgeordneten, in Fig. 2 strichpunktiert dargestellten Speicherwagen zugeführt werden. Parallel dazu kann von einem am hinteren Maschinenende angekuppelten Speicherwagen (s. Fig. 1) neuer Schotter in eine Einwurföffnung 44 des Einwurftrichters 31 abgeworfen und über die Entladeschurren 32 gezielt auf das Erdplanum 47 abgeworfen werden. Diese Zuführung von neuem Schotter kann in vorteilhafter Weise auch als Ergänzung vorgesehen werden, wenn der abgesaugte und über die Fördereinrichtung 33 wieder eingebrachte alte Schotter mengenmäßig nicht ausreichend vorhanden ist.If the extracted ballast is very dirty and therefore no longer reusable, it can be fed to an upstream storage trolley shown in dash-dot lines in FIG. 2 by dropping onto the conveyor belt arrangement 23 via the loading conveyor belt 25. At the same time, new ballast can be thrown into a throw-in opening 44 of the throw-in funnel 31 from a storage wagon (see FIG. 1) coupled to the rear end of the machine and can be dropped specifically onto the ground level 47 via the discharge chutes 32. This supply of new ballast can advantageously also be provided as a supplement if the amount of old ballast that has been extracted and reintroduced via the conveyor device 33 is insufficient.
