Description

Die Erfindung betrifft eine Anlage zur Untergrundsanierung einer Schotterbettung eines Gleises mit einem im Arbeitseinsatz endseitig jeweils auf einem Schienenfahrwerk abgestützten Maschinenrahmen und zwei in Maschinenlängsrichtung voneinander distanzierten und unabhängig voneinander höhenverstellbaren, zwischen den Schienenfahrwerken angeordneten Räumvorrichtungen zur Entfernung von unterhalb des Gleises befindlichem Schotter der Schotterbettung, wobei die in Arbeitsrichtung vordere Räumvorrichtung zur Entfernung lediglich einer oberen Schichte der Schotterbettung und die nachfolgende hintere Räumvorrichtung für den Aushub des restlichen Schotters und eines angrenzenden Erdplanums ausgebildet ist.The invention relates to a system for the underground rehabilitation of a ballast bed of a track with one end at work end one machine-supported machine frame and two in the machine's longitudinal direction distant from each other and independent of each other height-adjustable, arranged between the rail carriages Broaching devices for removal from below the track Ballast of the ballast bed, the front one in the working direction Clearing device for removing only an upper layer of the ballast bed and the subsequent rear clearing device for excavation the rest of the ballast and an adjacent earth level is.

Durch die US 4 479 439 ist bereits eine Anlage zur Sanierung des Gleisunterbaues bekannt, wobei diese Sanierung durch Herstellung einer aus einem Kies-Sand-Gemisch gebildeten Planumschutzschichte zwischen Erdplanum und Schotterbettung im Zuge einer kontinuierlichen Arbeitsvorfahrt erzielt wird. Diese Anlage weist zwischen zwei Schienenfahrwerken eine höhenverstellbare Räumvorrichtung und Förderbänder zur Aufnahme und zum Abtransport des Altschotters auf. In Arbeitsrichtung unmittelbar hinter der Räumvorrichtung befindet sich das Abwurfende einer aus mehreren in Maschinenlängsrichtung hintereinander angeordneten Förderbändern gebildeten Förderbandanordnung zum Transport von die Planumschutzschichte bildendem Sand. Hinter diesem Abwurfende zur Einbringung des Sandes befindet sich ein Abwurfende einer weiteren Förderbandanordnung zur Einbringung von neuem Schotter. Mit dieser Anlage wird das Gleis etwa mittig zwischen den auf dem Gleis aufliegenden Schienenfahrwerken angehoben und der darunter befindliche verschmutzte Schotter kontinuierlich entfernt. Parallel dazu erfolgt eine kontinuierliche Einbringung des Sandes, der auf das Gleis abgeworfen wird und durch die Schwellenfächer auf das freigelegte Erdplanum fällt. Ebenfalls parallel dazu wird kontinuierlich auf die inzwischen verdichtete Planumschutzschichte neuer Schotter abgeworfen und planiert. Through US 4,479,439 there is already a facility for the refurbishment of the track substructure known, this renovation by producing a a layer of protective layer formed between gravel and sand Ground level and ballast bedding as part of a continuous work approach is achieved. This system points between two rail bogies a height-adjustable clearing device and conveyor belts for picking up and to remove the old ballast. Immediately in the direction of work behind the clearing device is the discharge end one of several Conveyor belts arranged one behind the other in the machine longitudinal direction formed conveyor belt arrangement for transporting the formation protection layer forming sand. Behind this drop end for introduction the sand is a drop end of another conveyor arrangement for the introduction of new ballast. With this system the track will be approximately in the middle between the rail bogies resting on the track raised and the dirty one underneath Gravel removed continuously. In parallel, there is a continuous Introduction of the sand that is thrown onto the track and through the Threshold fans fall on the exposed earth level. Also in parallel to this end, we are continually working on the compacted protective layer new ballast dropped and leveled.

In der US 4 357 874 wird eine weitere, aus zwei voneinander unabhängig verfahrbaren Gleisbaufahrzeugen gebildete Anlage zur Planumsanierung beschrieben. Jedes dieser beiden mit einem brückenförmigen Maschinenrahmen ausgestatteten Gleisbaufahrzeuge weist an einem Ende ein höhenverstellbares Raupenfahrwerk auf, dem beidseits ein Schienenfahrwerk zugeordnet ist. Zur Einleitung der Planumsanierung wird mit Hilfe des ersten Gleisbaufahrzeuges ein die Umbaulücke abdeckendes Gleisjoch abgehoben und auf das anschließende Gleis transportiert. Danach wird mit Hilfe einer am zweiten Gleisbaufahrzeug befindlichen Räumvorrichtung der verschmutzte Schotter entfernt. Im darauffolgenden, wiederum durch das erste Gleisbaufahrzeug durchgeführten Arbeitsschritt wird Sand sowie neuer Schotter in die Umbaulücke eingebracht und verdichtet. Abschließend wird das Gleisjoch wieder auf die sanierte Umbaulücke abgelegt. Ein derartiges Verfahren eignet sich zur Sanierung kurzer Gleisabschnitte.In US 4,357,874 a further one, consisting of two, is independent of one another traversable track construction vehicles formed system for redevelopment described. Each of these two with a bridge-shaped machine frame equipped track construction vehicles has a height-adjustable at one end Crawler undercarriage on which a rail undercarriage is assigned on both sides is. With the help of the first Track construction vehicle lifted a track yoke covering the conversion gap and transported to the next track. Then with the help of a the dirty clearing device located on the second track construction vehicle Gravel removed. In the following, again by the first track construction vehicle carried out step sand and new gravel brought into the gap and compacted. Finally, the Gleisjoch again placed on the redeveloped gap. Such a process is suitable for the renovation of short track sections.

Gemäß UIC-Codex 722 E vom 1. Jänner 1990 des Internationalen Eisenbahnverbandes, Seite 11, ist ein weiteres Verfahren zur Verbesserung des Planums von Gleisen bekannt. Dabei wird in einem ersten Verfahrensschritt der verschmutzte Schotter mit Hilfe einer Bettungsreinigungsmaschine zur Gänze entfernt. Das Aushubmaterial wird teilweise seitlich abgelagert oder auf geeignete Silowagen verladen. In einem weiteren Verfahrensschritt wird das freigelegte Erdplanum geglättet, gegebenenfalls ein Geotextil verlegt und das Gleis auf das Erdplanum abgelegt. In weiterer Folge wird ein Kies-Sand-Gemisch aus Selbstentladewagen abgeladen und mit einer Schotterplaniermaschine auf die erforderliche Höhe verteilt. Der nächstfolgende Arbeitseinsatz wird mit einer Stopf-Richtmaschine durchgeführt, mit der der Gleisrost angehoben und das Kies-Sand-Gemisch unter den Schwellen mit vergrößerten Stopfpickeln verdichtet wird. Abschließend erfolgt ein Abladen von Schotter aus Selbstentladewagen, eine Anhebung des Gleises, dessen Unterstopfung und eine Gleislagekorrektur.According to UIC code 722 E of January 1, 1990 of the International Union of Railways, Page 11, is another method of improving the Known formations of tracks. In a first process step the dirty ballast with the help of a ballast cleaning machine Entirely removed. The excavated material is partly deposited on the side or loaded onto suitable silo wagons. In a further process step the exposed earth level is smoothed, if necessary a geotextile is laid and placed the track on the ground level. Subsequently, a gravel-sand mixture unloaded from self-unloading wagons and with a ballast leveling machine distributed to the required height. The next work assignment is carried out with a tamping straightening machine with which the track grate raised and the gravel-sand mixture under the sleepers with enlarged Darning is compressed. Finally there is an unloading of Ballast from self-unloading wagons, a raising of the track, its tamping and a track correction.

Die DD-A-240 043 beschreibt eine Schotterbettreinigungsmaschine, auf deren einteilig ausgebildetem Maschinenrahmen hintereinander zwei Räumketten angeordnet sind. Die vordere Räumkette dient zum Ausheben des Bettungsschotters und Abwurf desselben in eine Siebanlage, während die zweite Räumkette eine darunterliegende, auszuwechselnde Sanierungsschicht aufnimmt und diese direkt dem Abraumförderband der Siebanlage zuführt.The DD-A-240 043 describes a ballast bed cleaning machine on the one-piece machine frame two clearing chains in a row are arranged. The front clearing chain is used to lift the ballast ballast and dropping it into a screening plant while the second Clearing chain an underlying, replaceable renovation layer picks up and feeds it directly to the overburden conveyor belt of the screening plant.

Schließlich ist noch durch die DE 42 37 712 A 1 eine weitere Anlage zur Gleisunterbausanierung bekannt. Diese Anlage setzt sich aus zwei voneinander getrennten Gleisbaufahrzeugen zusammen, wobei dem ersten Fahrzeug eine Räumvorrichtung zur Entfernung des Altschotters und dem zweiten Fahrzeug eine Gleishebevorrichtung sowie eine Planier- und Verdichteinrichtung zugeordnet ist.Finally, DE 42 37 712 A 1 is another system for Track substructure renovation known. This system is made up of two separate track construction vehicles together, the first vehicle a clearing device for removing the old ballast and the second Vehicle a track lifting device and a leveling and compacting device assigned.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer eingangs beschriebenen Anlage, mit der im Zuge einer leistungsfähigen kontinuierlichen Arbeitsvorfahrt eine vereinfachte und wirtschaftlichere Unterbausanierung durchführbar ist.The object of the present invention is to create an input described system with which in the course of a powerful continuous Work Priority a simplified and more economical substructure renovation is feasible.

Erfindungsgemäß wird diese Aufgabe mit einer Anlage der eingangs beschriebenen Art dadurch gelöst, daß der eine Gleishebevorrichtung aufweisende Maschinenrahmen aus zwei durch ein allseitig wirksames Gelenk miteinander verbundenen Rahmenteilen gebildet ist, wobei jedem Rahmenteil eine Räumvorrichtung und jeder der beiden Räumvorrichtungen eine eigene Förderbandanordnung zugeordnet ist, und daß im Bereich des Gelenkes ein Schienenfahrwerk und ein beide Rahmenteile miteinander verbindender Antrieb vorgesehen ist.According to the invention, this object is achieved with a system as described in the introduction Art solved in that the track lifting device Machine frame made of two by a joint effective on all sides connected frame parts is formed, each frame part one clearing device and each of the two clearing devices has its own Conveyor belt arrangement is assigned, and that in the region of the joint Rail undercarriage and a drive connecting both frame parts is provided.

Durch die erfindungsgemäße Anordnung von zwei - jeweils eine eigene Förderbandanordnung aufweisenden - Räumvorrichtungen innerhalb der Biegelinie des angehobenen Gleises (bzw. innerhalb des Arbeitsbereiches) ist in vorteilhafter Weise bei erhöhter Leistungsfähigkeit der Schotterbetträumung eine wirtschaftliche Wiederverwendung des noch brauchbaren Schotters möglich. Durch dessen Aufnahme mittels einer eigenen Räumvorrichtung besteht die Möglichkeit, lediglich die obere Schichte der Schotterbettung aufzunehmen und die untere, mit Erdreich vermengte Schotterschichte über die zugeordnete zweite Förderbandanordnung zur Gänze zu entfernen. Da sich beide Räumvorrichtungen innerhalb des angehobenen Gleisbereiches befinden, kann in Abhängigkeit des Verschmutzungsgrades bzw. auch der benötigten Schottermengen eine rasche Änderung der durch die vordere Räumvorrichtung bearbeiteten Schichthöhe durchgeführt werden. Außerdem kann durch den Einsatz einer eigenen hinteren Räumvorrichtung das freigelegte Erdplanum problemlos relativ tief positioniert werden, so daß die Einbringung der Planumschutzschichte ohne Veränderung der absoluten Gleislage möglich ist.Due to the arrangement according to the invention of two, each having its own conveyor belt arrangement having - broaching devices within the bending line of the raised track (or within the work area) is in advantageously with increased performance of the ballast bed clearing economic reuse of the still usable ballast possible. By taking it in by means of its own clearing device the possibility of only taking up the upper layer of the ballast bed and the lower layer of gravel mixed with soil over the to completely remove the assigned second conveyor belt arrangement. That I both clearing devices are located within the raised track area, can depend on the degree of pollution or the required Gravel amounts a rapid change due to the front clearing device processed layer height can be carried out. Besides, can by using its own rear clearing device Earth planum can easily be positioned relatively deep, so that the introduction the level protection layer without changing the absolute track position is possible.
