Description

Die Erfindung betrifft eine Saugmaschine mit einem auf Schienenfahrwerken verfahrbaren, einen Unterdruckerzeuger sowie einen Schotterspeicher aufweisenden Maschinenrahmen, einer endseitig auf diesem angeordneten Fahrkabine und einer höhenverstellbaren Saugdüse, die über das die Fahrkabine aufweisende Maschinenende vorkragend angeordnet und durch ein über der Fahrkabine befindliches Absaugrohr mit dem Schotterspeicher verbunden ist.The invention relates to a suction machine with a machine frame that can be moved on rail bogies, has a vacuum generator and a ballast accumulator, a driver's cabin arranged at the end of the latter and a height-adjustable suction nozzle that projects cantilevered over the machine end that has the driver's cab and through a suction pipe with the ballast reservoir located above the driver's cabin connected is.

Eine derartige Saugmaschine ist durch die DE 21 36 306 A bekannt. Die auf dem vorkragenden Absaugrohr befestigte Saugdüse ist mit Vibratoren zur Lockerung der abzusaugenden Schottersteine ausgestattet. Das Absaugrohr selbst ist durch einen verdreh- und verschwenkbaren Ausleger oberhalb einer Fahrkabine abgestützt.Such a suction machine is known from DE 21 36 306 A. The suction nozzle attached to the projecting suction pipe is equipped with vibrators to loosen the ballast stones to be extracted. The suction pipe itself is supported by a rotating and swiveling boom above a driver's cabin.

Eine andere Saugmaschine ist bereits durch das Deutsche Gebrauchsmuster 90 00 529 bekannt, wobei zwei Saugdüsen auf einem durch Hilfsschienenfahrwerke am Gleis verfahrbaren Lastkraftwagen höhenverstellbar befestigt sind. Die beiden Saugdüsen sind in Maschinenquerrichtung im fixen Abstand zueinander angeordnet und werden im Arbeitseinsatz in einem konstanten geringen Abstand zur Gleisoberfläche geführt, um von dieser Verunreinigungen, wie z. B. Zigarettenreste oder dergleichen, abzusaugen.Another suction machine is already known from German utility model 90 00 529, two suction nozzles being fastened in a height-adjustable manner on a truck that can be moved on the track by auxiliary rail bogies. The two suction nozzles are arranged at a fixed distance from one another in the transverse direction of the machine and are guided at a constant short distance from the track surface during work in order to prevent contaminants such as e.g. B. cigarette residues or the like to suction.

Durch die GB 2 172 326 A ist es auch bereits bekannt, den Schotter einer Gleisbettung mit Hilfe von quer- und höhenverstellbaren Saugdüsen abzusaugen. Diesen sind jeweils rotierende Werkzeuge zur Auflockerung von verkrustetem Schotter zugeordnet. Um eine kontinuierliche Vorwärtsbewegung der Saugmaschine zu ermöglichen, sind die Saugdüsen relativ zum Maschinenrahmen längsverschiebbar angeordnet. Nach Zentrierung über einem Schwellenfach werden die Saugdüsen in den Schotter abgesenkt, wobei der Schotter auch in den angrenzenden Bereichen unterhalb der Schwellen abgesaugt wird. Der auf diese Weise zur Gänze abgesaugte Schotter einer Schotterbettung wird einer Reinigungsanlage zugeführt und anschließend im gereinigten Zustand wiederum auf das freigelegte Planum abgeworfen.From GB 2 172 326 A it is also already known to vacuum the ballast of a track bed with the help of cross-adjustable and height-adjustable suction nozzles. These are assigned rotating tools to loosen crusted gravel. In order to enable a continuous forward movement of the suction machine, the suction nozzles are arranged to be longitudinally displaceable relative to the machine frame. After centering over a sleeper compartment, the suction nozzles are lowered into the ballast, whereby the ballast is also extracted in the adjacent areas below the sleepers. The ballast that has been completely extracted in this way from a ballast bed is fed to a cleaning system and then thrown off again in the cleaned state onto the exposed formation.

Durch das Deutsche Gebrauchsmuster 82 36 650 ist eine weitere Saugmaschine mit einer höhenverstellbaren Saugdüse bekannt. Die über diese Saugdüse aus dem Gleisrost oder neben dem Gleisrost aufgenommenen Schottersteine werden in einen Sammelbehälter geführt und von diesem aus auf einen Rüttelboden zur Reinigung abgegeben. Das untere Ende der Saugdüse ist mit einer speziell gestalteten Gummischürze verbunden.Another suction machine with a height-adjustable suction nozzle is known from German utility model 82 36 650. The ballast stones picked up via this suction nozzle from the track grate or next to the track grate are combined into one Guided collection container and from this on a vibrating floor for cleaning. The lower end of the suction nozzle is connected to a specially designed rubber apron.

Weitere Saugmaschinen sind noch durch die US 4 741 072, DE 41 08 673 und das Deutsche Gebrauchsmuster 89 13 731.0 bekannt.Further suction machines are also known from US 4,741,072, DE 41 08 673 and German utility model 89 13 731.0.

Die Aufgabe der vorliegenden Erfindung besteht nun in der Schaffung einer Saugmaschine der eingangs beschriebenen Art, die bei uneingeschränkter Einsehbarkeit von der Fahrkabine auf die Saugdüse eine möglichst leistungsfähige Räumung insbesondere von Schwellenfächern ermöglicht.The object of the present invention is now to provide a suction machine of the type described in the introduction which, with unrestricted visibility from the driver's cab onto the suction nozzle, enables the most efficient clearing possible, in particular of threshold compartments.

Diese Aufgabe wird erfindungsgemäß mit der eingangs genannten Saugmaschine dadurch gelöst, daß die Saugdüse jeweils mittels eigener, unabhängig voneinander beaufschlagbarer Antriebe gemäß einem XYZ-Koordinatensystem in einer in Maschinenlängsrichtung sowie in einer senkrecht dazu verlaufenden und in vertikaler Richtung verstellbar ausgebildet ist.This object is achieved according to the invention with the suction machine mentioned at the outset in that the suction nozzle is designed to be adjustable in each case by means of its own drives which can be acted on independently of one another in accordance with an XYZ coordinate system in a machine longitudinal direction and in a direction perpendicular thereto and in a vertical direction.

Eine derartige Ausbildung ermöglicht bei relativ einfacher konstruktiver Gestaltung eine verbesserte Steuerung der Saugdüse gemäß XYZ-Koordinaten, so daß mit einer rascheren und gezielteren Positionierung der Saugdüse eine wesentliche Verbesserung der Saugleistung erzielbar ist. Dies ist insbesondere für die Absaugung des Schotters aus einer Vielzahl von eng begrenzten Bereichen, wie z. B. Schwellenfächern, von großem Vorteil. Die gezielte Steuerung der Saugdüse kann ohne jedwede Einschränkung in vorteilhafter Weise in der Fahrkabine durchgeführt werden.Such a design enables improved control of the suction nozzle according to XYZ coordinates with a relatively simple structural design, so that a significant improvement in the suction power can be achieved with faster and more targeted positioning of the suction nozzle. This is especially for the suction of the ballast from a variety of narrow areas, such. B. threshold subjects, of great advantage. The targeted control of the suction nozzle can advantageously be carried out in the driver's cabin without any restriction.

Die Ausbildung der Tragkonstruktion gemäß den Ansprüchen 2 und 3 ermöglicht auch eine problemlose Verschwenkung der Saugdüse in den Schwellenvorkopfbereich, wobei weiterhin eine uneingeschränkte Verstellung gemäß den XYZ-Koordinaten durchführbar ist.The design of the support structure according to claims 2 and 3 also enables a problem-free pivoting of the suction nozzle into the front area of the sleeper, furthermore an unrestricted adjustment according to the XYZ coordinates can be carried out.

Die Weiterbildung der Tragkonstruktion nach den Ansprüchen 4, 5 und 6 hat eine noch bessere Führung und Anpassung der Saugdüse an bei der Absaugung zu umgehende Hindernisse zur Folge. Durch eine Schrägstellung der Saugdüse mit Hilfe des Rotators ist der Schotter auch in unterhalb der Schwellen gelegenen Bereichen gezielter absaugbar.The development of the support structure according to claims 4, 5 and 6 has an even better guidance and adaptation of the suction nozzle to obstacles to be avoided during suction. By tilting the suction nozzle with the help of the rotator, the ballast can be extracted more precisely even in areas below the sleepers.

Die Weiterbildung der Saugmaschine nach den Ansprüchen 7 und 8 hat den besonderen Vorteil, daß die beiden Schotterspeicher unter Erzielung einer kontinuierlichen Ansaugung abwechselnd entleerbar sind.The development of the suction machine according to claims 7 and 8 has the particular advantage that the two ballast stores can be emptied alternately while achieving a continuous suction.

Mit der Weiterbildung nach Anspruch 9 ist die Saugdüse in vorteilhafter Weise in Verbindung mit der Maschinenvorfahrt von der Kabine aus steuerbar.With the development according to claim 9, the suction nozzle can be controlled in an advantageous manner in connection with the machine approach from the cabin.

Schließlich ermöglicht die Weiterbildung nach den Ansprüchen 10, 11 und 12 einen leistungsfähigen Abtransport des angesaugten Schüttgutes auf nachfolgende Speicherwagen. Mit der wahlweisen Beaufschlagbarkeit des Förderantriebes in beiden Drehrichtungen ist das angesaugte Schüttgut bedarfsweise mit Hilfe des Übergabeförderbandes wiederum auf das Gleis abwerfbar.Finally, the further development according to claims 10, 11 and 12 enables efficient removal of the sucked bulk material onto subsequent storage trolleys. With the optional actuation of the conveyor drive in both directions of rotation, the bulk material sucked in can, if necessary, be thrown onto the track with the aid of the transfer conveyor belt.

Im folgenden wird die Erfindung anhand in der Zeichnung dargestellter Ausführungsbeispiele näher beschrieben.The invention is described in more detail below with reference to exemplary embodiments shown in the drawing.

Zur Führung und Abstützung einer über ein Maschinenende 9 vorkragenden Saugdüse 10 ist eine am Maschinenrahmen 4 befestigte Tragkonstruktion 11 vorgesehen. Diese setzt sich aus zwei in Maschinenlängsrichtung hintereinander angeordneten und unter Bildung einer Gelenkstelle mit einer vertikalen Schwenkachse 12 und einem Schwenkantrieb 13 gelenkig miteinander verbundenen Teilen 14,15 zusammen. Diese Tragkonstruktion wird in Fig. 2 noch näher beschrieben.A support structure 11 fastened to the machine frame 4 is provided for guiding and supporting a suction nozzle 10 projecting over a machine end 9. This is composed of two parts 14, 15 arranged one behind the other in the longitudinal direction of the machine and forming an articulation point with a vertical swivel axis 12 and a swivel drive 13. This support structure is described in more detail in FIG. 2.

An die mit dem Teil 15 verbundene Saugdüse 10 schließt ein flexibles Absaugrohr 16 an, dessen der Saugdüse 10 gegenüberliegendes Ende 49 senkrecht zur Maschinenlängsrichtung verschiebbar gelagert ist. Zur Speicherung des angesaugten Schotters sind zwei in Maschinenquerrichtung einander gegenüberliegende Schotterspeicher 17,18 mit jeweils einer Entladeöffnung 19 vorgesehen. Zwischen diesen Schotterspeichern 17,18 und dem Unterdruckerzeuger 3 befinden sich zwei Filterkammern 20 mit verschließbaren Entladeöffnungen 21.The suction nozzle 10 connected to the part 15 is followed by a flexible suction pipe 16, the end 49 of which is opposite the suction nozzle 10 and is displaceably mounted perpendicular to the longitudinal direction of the machine. To store the suctioned ballast, two ballast stores 17, 18 opposite each other in the cross-machine direction are provided, each with an unloading opening 19. Two filter chambers 20 with closable discharge openings 21 are located between these ballast stores 17, 18 and the vacuum generator 3.

Unterhalb der Entladeöffnungen 19 der beiden Schotterspeicher 17,18 und der Entladeöffnungen 21 der Filterkammern 20 sowie unterhalb des Maschinenrahmens 4 ist ein in Maschinenlängsrichtung verlaufendes Förderband 22 mit einem Drehantrieb 23 vorgesehen.

Dem genannten Ende 24 des Förderbandes 22 ist ein mit einem Aufnahmeende 25 unterhalb des Förderbandes 22 angeordnetes Übergabeförderband 26 zugeordnet. Dieses ist auf einer durch einen Drehantrieb 27 um eine vertikale Drehachse 28 drehbar am Maschinenrahmen 4 befestigten Abstützung 29 gelagert und in bezug auf diese durch einen Antrieb 30 in Maschinenlängsrichtung - in eine in strichpunktierten Linien dargestellte Überstellposition - verschiebbar ausgebildet. Ein dem Übergabeförderband 26 zugeordneter Förderantrieb 31 ist wahlweise in beiden Drehrichtungen beaufschlagbar.Below the unloading openings 19 of the two ballast stores 17, 18 and the unloading openings 21 of the filter chambers 20 and below the machine frame 4, a conveyor belt 22 with a rotary drive 23 running in the machine longitudinal direction is provided. An end 24 of this conveyor belt 22, which is further distanced from the suction nozzle 10, is positioned above the rail undercarriage 2 fastened to the end of the machine frame 4 and below the driving cabin 5. A transfer conveyor belt 26, which is arranged below the conveyor belt 22 with a receiving end 25, is assigned to said end 24 of the conveyor belt 22. This is mounted on a support 29, which is fastened to the machine frame 4 by a rotary drive 27 about a vertical axis of rotation 28, and is displaceable in relation to this by a drive 30 in the machine longitudinal direction - into a transfer position shown in dash-dotted lines. A conveyor drive 31 assigned to the transfer conveyor belt 26 can optionally be acted upon in both directions of rotation.

Wie in Fig. 2 ersichtlich, ist der über der Fahrkabine 5 befindliche Teil 14 der Tragkonstruktion 11 aus einem in Maschinenlängsrichtung verlaufenden, durch einen Antrieb 32 in Maschinenlängsrichtung teleskopisch verlängerbaren Hauptträger 33 gebildet. Dieser ist in seinem von der Saugdüse 10 weiter enfternten Endbereich durch einen Antrieb 34 auf quer zur Maschinenlängsrichtung verlaufenden horizontalen Querführungen 35 verschiebbar gelagert und weist in seinem anderen Endbereich die Gelenkstelle mit der Schwenkachse 12 auf.As can be seen in FIG. 2, the part 14 of the supporting structure 11 which is located above the driving cabin 5 is formed from a main carrier 33 which extends in the machine longitudinal direction and can be telescopically extended by a drive 32 in the machine longitudinal direction. In its end region, which is further removed from the suction nozzle 10, this is displaceably supported by a drive 34 on horizontal transverse guides 35 running transversely to the machine longitudinal direction, and in its other end region it has the articulation point with the pivot axis 12.

This in turn is connected to a height guide 38, on which a second support body 39 is mounted in a height-adjustable manner by a first height adjustment drive 40. The height adjustment of the parallelogram linkage 37 together with the suction nozzle 10 is carried out by a second height adjustment drive 41. The lower end of the second support body 39 is connected to a rotator 42, by means of which a support plate 43 connected to the suction nozzle 10 can be rotated about a vertical axis of rotation 44. The suction nozzle 10 is pivotally connected to the support plate 43 via a pivot axis 45 which runs perpendicular to the longitudinal direction of the nozzle or the machine or horizontally. A nozzle swivel drive 46 is provided for pivoting the suction nozzle about said swivel axis 45.

Wie in Fig. 3 ersichtlich, weist jeder der beiden Schotterspeicher 17,18 eine eigene Ansaugöffnung 47,48 auf. Das von der Saugdüse 10 abgewandte Ende 49 des Absaugrohres 16 ist durch einen Antrieb 50 von der ersten zur zweiten Ansaugöffnung 47,48 verschiebbar gelagert. Dazu ist ein mit dem Ende 49 des Absaugrohres 16 und mit dem Antrieb 50 verbundener Flansch 51 in einer die beiden Ansaugöffnungen 47,48 miteinander verbindenden Kulissenführung 52 gelagert. Sämtliche auf der die Saugdüse 10 abstützenden Tragkonstruktion 11 befindlichen Antriebe sind durch die in der Fahrkabine 5 befindliche Steuereinrichtung 6 steuerbar.As can be seen in FIG. 3, each of the two ballast stores 17, 18 has its own suction opening 47, 48. The end 49 of the suction tube 16 facing away from the suction nozzle 10 is mounted so as to be displaceable by a drive 50 from the first to the second suction opening 47, 48. For this purpose, a flange 51 connected to the end 49 of the suction pipe 16 and to the drive 50 is mounted in a link guide 52 which connects the two suction openings 47, 48 to one another. All of the drives located on the support structure 11 supporting the suction nozzle 10 can be controlled by the control device 6 located in the driving cabin 5.

Wie in Fig. 4 ersichtlich, ergibt sich aus der speziellen Tragkonstruktion 11 ein sehr weiter, durch eine strichpunktierte Begrenzungslinie angedeuteter Einsatzbereich, in dem problemlos auch seitlich neben einem Gleis 53 befindlicher Schotter absaugbar ist.As can be seen in FIG. 4, the special support structure 11 results in a very wide range of use, indicated by a dash-dotted boundary line, in which ballast located laterally next to a track 53 can also be extracted without problems.

Im Arbeitseinsatz kann die Saugdüse 10 über die zentrale Steuereinrichtung 6 direkt von der Fahrkabine 5 aus richtig positioniert und zur Absaugung abgesenkt werden. Dabei erfolgt zweckmäßigerweise mit Hilfe des zweiten Höhenverstellantriebes 41 eine erste, annähernde Absenkung der Saugdüse 10 in die gewünschte Höhe, die dann mit Hilfe des ersten Höhenverstellantriebes 40 exakt einstellbar ist. Durch den Rotator 42 ist die Saugdüse um insgesamt 180° um die Drehachse 44 verschwenkbar, wodurch insbesondere in Verbindung mit einer zusätzlichen Verschwenkung durch den Düsenschwenkantrieb 46 auch unterhalb einer Schwelle 54 befindlicher Schotter absaugbar ist. Die Positionierung der Saugdüse 10 kann mit Hilfe der Antriebe 33,34 und 40 bzw. 41 in einfacher Weise entsprechend XYZ-Koordinaten durchgeführt werden. Mit Hilfe der Schwenkantriebe 13 ist die Saugdüse 10 in einen seitlich neben dem Gleis 53 befindlichen Bereich verschwenkbar.In work use, the suction nozzle 10 can be correctly positioned directly from the driver's cab 5 via the central control device 6 and lowered for suction. The second height adjustment drive 41 expediently brings about a first, approximately lowering of the suction nozzle 10 to the desired height, which can then be adjusted exactly with the aid of the first height adjustment drive 40. The suction nozzle can be pivoted by a total of 180 ° about the axis of rotation 44 by the rotator 42, which means that ballast located below a threshold 54 can also be sucked off, in particular in connection with an additional pivoting by the nozzle swivel drive 46. The positioning of the suction nozzle 10 can be done with With the help of the drives 33, 34 and 40 or 41, they can be carried out in a simple manner according to XYZ coordinates. With the help of the pivot drives 13, the suction nozzle 10 can be pivoted into an area located to the side of the track 53.

Sobald einer der beiden Schotterspeicher 17 bzw. 18 gefüllt ist, erfolgt durch einen entsprechenden Sensor eine automatische Beaufschlagung des Antriebes 50, der das Ende 49 des Absaugrohres 16 zum benachbarten Schotterspeicher 17 bzw. 18 verschiebt. Anschließend erfolgt parallel zur Schotteransaugung in den leeren Schotterspeicher eine Entleerung des gefüllten Schotterspeichers 17 bzw. 18 durch Öffnen der entsprechenden Entladeöffnung 19. Der auf diese Weise entleerte Schotter wird unter Beaufschlagung des Antriebes 23 über das Förderband 22 und das Übergabeförderband 26 auf einen an die Saugmaschine 1 angeschlossenen Verladewagen 55 transportiert und gespeichert. Gleichzeitig mit der automatischen Beaufschlagung des Antriebes 50 erfolgt auch eine automatische Umsteuerung des Ansaugstromes von einer der ersten Filterkammer 20 zugeordneten Ansaugöffnung 56 zu einer der zweiten Filterkammer 20 zugeordneten Ansaugöffnung 57 bzw. umgekehrt. Die Entleerung der beiden Filterkammern 20 erfolgt ebenso wie jene der Schotterspeicher 17,18 über das Förderband 22 und das Übergabeförderband 26.As soon as one of the two ballast stores 17 and 18 is filled, the drive 50 is automatically acted upon by a corresponding sensor, which moves the end 49 of the suction pipe 16 to the adjacent ballast store 17 or 18. Subsequently, parallel to the ballast suction in the empty ballast store, the filled ballast store 17 or 18 is emptied by opening the corresponding discharge opening 19. The ballast emptied in this way is loaded onto the suction machine by the drive 23 via the conveyor belt 22 and the transfer conveyor belt 26 1 connected loading wagon 55 transported and stored. Simultaneously with the automatic loading of the drive 50, there is also an automatic reversal of the intake flow from an intake opening 56 assigned to the first filter chamber 20 to an intake opening 57 assigned to the second filter chamber 20 or vice versa. The emptying of the two filter chambers 20, like that of the ballast stores 17, 18, takes place via the conveyor belt 22 and the transfer conveyor belt 26.

Für den Fall, daß der angesaugte und infolge der Filterung der Absaugluft gegebenenfalls auch gereinigte Schotter zur Einschotterung eines Gleisabschnittes benötigt wird, erfolgt eine Verschiebung des Übergabeförderbandes 26 mit Hilfe des Antriebes 30 in die mit strichpunktierten Linien dargestellte Überstellposition. Parallel dazu wird der Förderantrieb 31 in die Gegenrichtung beaufschlagt, so daß der vom Schotterspeicher 17 bzw. 18 auf das Förderband 22 abgeworfene Schotter von diesem auf das eingefahrene Übergabeförderband 26 transportiert wird, wobei dieses den Schotter in der durch einen Pfeil 58 angedeuteten Richtung auf das Gleis 53 abwirft.In the event that the sucked-in and, if necessary, cleaned ballast due to the filtering of the suction air is required for the ballasting of a track section, the transfer conveyor belt 26 is shifted with the aid of the drive 30 into the transfer position shown in dash-dotted lines. In parallel, the conveyor drive 31 is acted on in the opposite direction, so that the ballast thrown from the ballast store 17 or 18 onto the conveyor belt 22 is transported by the latter onto the retracted transfer conveyor belt 26, the ballast in the direction indicated by an arrow 58 onto the Track 53 sheds.

Für die Überstellfahrt wird der vorkragende Teil 15 der Tragkonstruktion 11 in die in Fig. 2 mit strichpunktierten Linien angedeutete Position seitlich neben der Fahrkabine 5 innerhalb des Lichtraumprofiles verbracht. Damit ist für die in der Fahrkabine 5 befindliche Bedienungsperson eine uneingeschränkte Sicht auf das Gleis gewährleistet.For the transfer travel, the projecting part 15 of the supporting structure 11 is brought into the position indicated by dash-dotted lines in FIG. 2 to the side next to the driver's cab 5 within the clearance profile. This ensures an unrestricted view of the track for the operator in the driver's cab 5.
