Description

Die Erfindung betrifft eine Saugmaschine zum Ansaugen von Schotter, mit einem auf Fahrwerken verfahrbaren, einen Unterdruckerzeuger und einen Schotterspeicher aufweisenden Maschinenrahmen sowie mit einem durch eine Verschiebeeinrichtung mit Antrieben quer- und höhenverstellbaren Saugrohr, wobei ein durch die Verschiebeeinrichtung bewegbarer, eine Längsachse aufweisender Saugrohr-Endabschnitt eine Saugöffnung zur Schotteraufnahme aufweist.The invention relates to a suction machine for sucking in ballast, with a machine frame that can be moved on undercarriages, has a vacuum generator and a ballast accumulator, and with a suction pipe that can be adjusted transversely and height by means of a displacement device with drives has a suction opening for ballast pick-up.

Durch die GB 2 172 326 A ist es bereits bekannt, insgesamt drei in vertikaler Richtung angeordnete Endabschnitte von Saugrohren im Bereich der Saugöffnungen mit rotierenden Werkzeugen zur Auflockerung von verkrustetem Schotter auszustatten. Die Endabschnitte sind jeweils durch eigene Antriebe einer Verschiebevorrichtung höhen- und querverstellbar ausgebildet. Um eine kontinuierliche Vorwärtsbewegung der Saugmaschine zu ermöglichen, sind die Endabschnitte der Saugrohre relativ zum Maschinenrahmen längsverschiebbar angeordnet. Nach Zentrierung über einem Schwellenfach werden die Endabschnitte mit den Saugöffnungen in den Schotter abgesenkt, wobei infolge einer Verdrehung der Werkzeuge auch in den angrenzenden Bereichen unterhalb der Schwellen befindlicher Schotter absaugbar ist.From GB 2 172 326 A it is already known to equip a total of three end sections of suction pipes arranged in the vertical direction in the area of the suction openings with rotating tools for loosening encrusted ballast. The end sections are each height-adjustable and transverse-adjustable by their own drives of a displacement device. In order to enable a continuous forward movement of the suction machine, the end sections of the suction pipes are arranged to be longitudinally displaceable relative to the machine frame. After centering over a sleeper compartment, the end sections with the suction openings are lowered into the ballast, and due to a rotation of the tools, ballast located in the adjacent areas below the sleepers can also be extracted.

Eine andere, durch die DE 71 27 884 U bekannte Saugmaschine weist eine im Bereich der Saugöffnung am Endabschnitt des Saugrohres befestigte Vibrationseinrichtung auf, mit der die Zähne aufweisende Saugöffnung in Schwingungen versetzbar ist. In einer anderen Ausführungsform sind zur Auflockerung des Schotters walzenförmige Werkzeuge vorgesehen, die ebenfalls der Saugöffnung zugeordnet sind.Another suction machine known from DE 71 27 884 U has a vibration device fastened in the area of the suction opening at the end section of the suction pipe, with which the suction opening having the teeth can be set in vibration. In another embodiment, roller-shaped tools are provided for loosening the ballast, which are also assigned to the suction opening.

Weitere Saugmaschinen sind noch durch die DE 21 36 306 A, US 4 741 072, DE 41 08 673 A und DE 89 13 731 U bekannt.Further suction machines are also known from DE 21 36 306 A, US 4 741 072, DE 41 08 673 A and DE 89 13 731 U.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer Saugmaschine der gattungsgemäßen Art, mit der die durch den Saugstrom bewirkte Aufnahme des Schotters, insbesondere auch in verkrustetem Zustand, verbessert ist.The object of the present invention is to create a suction machine of the generic type with which the absorption of the ballast caused by the suction flow, in particular also in the encrusted state, is improved.

Diese Aufgabe wird erfindungsgemäß mit der eingangs genannten Saugmaschine dadurch gelöst, daß dem um seine Längsachse drehbar gelagerten Saugrohr-Endabschnitt ein Drehantrieb zugeordnet ist.This object is achieved with the suction machine mentioned at the outset in that a rotary drive is associated with the suction pipe end section rotatably mounted about its longitudinal axis.

Durch diese drehbare Ausbildung kann die Schotteraufnahme mit einem Minimum an konstruktivem Aufwand wesentlich verbessert werden. Dabei ist von besonderem Vorteil, daß infolge der Rotation der Saugöffnung und daraus resultierenden Relativbewegung zu den angrenzenden Schottersteinen diese in Bewegung versetzt werden. Diese mechanisch initiierte Anfangsbewegung wird anschließend mit Hilfe der Saugkraft beschleunigt fortgesetzt. Durch die erfindungsgemäße Drehung der Saugöffnung ist daher der Schotter rasch und mit größerer Leistung absaugbar.This rotatable design enables the ballast pick-up to be significantly improved with a minimum of design effort. It is particularly advantageous that due to the rotation of the suction opening and the resulting relative movement to the adjacent gravel stones, these are set in motion. This mechanically initiated initial movement is then accelerated with the help of the suction force. Due to the rotation of the suction opening according to the invention, the ballast can therefore be extracted quickly and with greater power.

Diese Absaugleistung läßt sich noch zusätzlich erhöhen, wenn gemäß einer weiteren Ausbildungsvariante der Erfindung im Bereich der Saugöffnung von dieser abstehende Mitnahmeorgane vorgesehen sind.This suction power can be increased even further if, according to a further embodiment of the invention, entrainment members projecting from the suction opening are provided.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention result from the subclaims.

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.

Show it:
  • 1 is a side view of a suction machine with a suction pipe attached at the end by a sliding device to a machine frame and projecting beyond the machine end,
  • Fig. 2 is a greatly enlarged partial view of a suction pipe end portion of the suction pipe, and

Die in Fig. 1 ersichtliche Saugmaschine 1 weist einen auf Schienenfahrwerken 2 verfahrbaren Maschinenrahmen 4 mit einem Unterdruckerzeuger 3 sowie eine endseitig angeordnete Fahrkabine 5 mit einer zentralen Steuereinrichtung 6 auf. Des weiteren ist die Saugmaschine 1 mit einem Motor für die Energieversorgung und einem Fahrantrieb 7 ausgestattet. Zur Führung und Abstützung eines über ein Maschinenende 8 vorkragenden Saugrohr-Endabschnittes 9 eines Saugrohres 10 ist eine am Maschinenrahmen 4 befestigte Verschiebeeinrichtung 11 bzw. Tragkonstruktion 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. Der Saugrohr-Endabschnitt 9 ist durch verschiedene Antriebe 13,21 entlang der XYZ-Raumkoordinaten verstellbar.The suction machine 1 shown in FIG. 1 has a machine frame 4 which can be moved on rail undercarriages 2 and has a vacuum generator 3 and a driving cabin 5 which is arranged at the end and has a central control device 6. Furthermore, the suction machine 1 is equipped with a motor for the energy supply and a travel drive 7. For guiding and supporting a suction pipe end section 9 of a suction pipe 10 projecting over a machine end 8, a displacement device 11 or supporting structure attached to the machine frame 4 is provided. 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. The intake pipe end section 9 can be adjusted by various drives 13, 21 along the XYZ spatial coordinates.

An den mit dem Teil 15 verbundenen Saugrohr-Endabschnitt 9 schließt ein flexibler Teil des Saugrohres 10 an, dessen einer Saugöffnung 16 gegenüberliegendes Ende 17 senkrecht zur Maschinenlängsrichtung und horizontal verschiebbar gelagert ist. Zur Speicherung des angesaugten Schotters sind zwei in Maschinenquerrichtung einander gegenüberliegende Schotterspeicher 18 mit jeweils einer Entladeöffnung vorgesehen. Zwischen diesen und dem Unterdruckerzeuger 3 befinden sich zwei Filterkammern mit verschließbaren Entladeöffnungen. Unterhalb dieser Entladeöffnungen ist ein in Maschinenlängsrichtung verlaufendes Förderband 19 vorgesehen, um den angesaugten Schotter auf einen angekuppelten Verladewagen 20 zu transportieren.A flexible part of the suction pipe 10 adjoins the suction pipe end section 9 connected to the part 15, its end 17 opposite a suction opening 16 being mounted perpendicularly to the machine longitudinal direction and horizontally displaceable. In order to store the intake of ballast, two ballast stores 18 opposite each other in the cross-machine direction are provided, each with an unloading opening. Between these and the vacuum generator 3 there are two filter chambers with closable discharge openings. A conveyor belt 19 running in the machine longitudinal direction is provided below these unloading openings in order to transport the sucked-in ballast onto a coupled loading wagon 20.

Wie in Fig. 2 ersichtlich, ist der zum Eintauchen in den Schotter vorgesehene Saugrohr-Endabschnitt 9 in seinem oberen, der Saugöffnung 16 entgegengesetzten Endbereich durch ein Rotationslager 22 um eine Längsachse 23 drehbar am angrenzenden flexiblen Bereich des Saugrohres 10 gelagert. Das mit dem Teil 15 der Verschiebeeinrichtung 11 verbundene Rotationslager 22 weist einen koaxial zum Saugrohr-Endabschnitt 9 angeordneten und mit diesem verbundenen Zahnkranz 24 auf, der in formschlüssiger Verbindung mit einem Antriebsritzel 25 eines hydraulischen Drehantriebes 26 steht.As can be seen in FIG. 2, the suction pipe end section 9 provided for immersion in the ballast is rotatably supported in its upper end area opposite the suction opening 16 by a rotary bearing 22 about a longitudinal axis 23 on the adjacent flexible area of the suction pipe 10. The rotary bearing 22 connected to the part 15 of the displacement device 11 has a toothed ring 24 which is arranged coaxially with the intake pipe end section 9 and is connected to the latter, and which is in positive connection with a drive pinion 25 of a hydraulic rotary drive 26.

Der zur Schotteraufnahme dienenden Saugöffnung 16 sind am zylinderförmigen Saugrohr-Endabschnitt 9 befestigte und in radialer Richtung verlaufende Mitnahmeorgane 27 zur Lockerung bzw. Bewegung der angrenzenden und aufzusaugenden Schottersteine zugeordnet. Die Mitnahmeorgane 27 sind bezüglich ihrer Längsrichtung in einem Winkel zur Längsachse 23 angeordnet, wobei die freien Enden 28 über eine durch die ringförmige Saugöffnung 16 gebildete sowie senkrecht zur Längsachse 23 verlaufende Saugebene 29 vorragend ausgebildet sind.The suction opening 16, which is used to hold the ballast, is associated with driving elements 27 fastened to the cylindrical end section 9 of the suction pipe and extending in the radial direction for loosening or moving the adjacent ballast stones to be sucked up. The entrainment members 27 are arranged at an angle to the longitudinal axis 23 with respect to their longitudinal direction, the free ends 28 being designed to be projecting over a suction plane 29 which is formed by the annular suction opening 16 and extends perpendicular to the longitudinal axis 23.

Im Arbeitseinsatz wird der Saugrohr-Endabschnitt 9 bzw. die Saugöffnung 16 mit Hilfe der zentralen Steuereinrichtung 6 von der Fahrkabine 5 aus beispielsweise über einem Schwellenfach positioniert und durch Beaufschlagung der Antriebe 13,21 auf den Schotter abgesenkt. Parallel dazu erfolgt unter Beaufschlagung des Drehantriebes 26 eine Rotation des Saugrohr-Endabschnittes 9 um dessen Längsachse 23, wodurch die mit der Saugöffnung 16 bzw. dem ebenfalls rotierenden Mitnahmeorgan 27 in Berührung kommenden Schottersteine mechanisch in eine Anfangsbewegung versetzt werden. In weiterer Folge werden diese Schottersteine durch den Saugstrom rascher angesaugt und einem der beiden Schotterspeicher 18 zugeführt. Durch eine überlagerte Querbewegung des Saugrohr-Endabschnittes 9 ist das Schwellenfach zur Gänze durch Absaugen ausräumbar.In work, the suction pipe end section 9 or the suction opening 16 is positioned with the help of the central control device 6 from the driver's cab 5, for example above a threshold compartment, and lowered onto the ballast by acting on the drives 13, 21. In parallel with this, when the rotary drive 26 is acted upon, the suction pipe end section 9 rotates about its longitudinal axis 23, as a result of which the ballast stones that come into contact with the suction opening 16 or the driving element 27, which also rotates, are mechanically set into an initial movement. Subsequently, these gravel stones are sucked in more quickly by the suction flow and fed to one of the two ballast stores 18. Due to a superimposed transverse movement of the suction pipe end section 9, the sleeper compartment can be completely cleared out by suction.

Zur Optimierung verschiedener spezieller Arbeiten, beispielsweise der Absaugung von Schotter unterhalb der Schwellen bzw. unterhalb von Linienleitern kann es vorteilhaft sein, die Mitnahmeorgane 27 durch deren verlängerte Ausbildung abzuändern. Dazu ist es zweckmäßig, den unteren, die Saugöffnung 16 und die Mitnahmeorgane 27 umfassenden Bereich des Saugrohr-Endabschnittes 9 durch eine Schnellkupplung lösbar mit dem restlichen Teil des Saugrohr-Endabschnittes 9 zu verbinden. Damit besteht die vorteilhafte Möglichkeit, in Anpassung an unterschiedliche Einsatzbedingungen bei einem Minimum an Umrüstzeiten jeweils optimal wirksame Mitnahmeorgane 27 einzusetzen.In order to optimize various special work, for example the extraction of ballast below the sleepers or below line conductors, it may be advantageous to extend the driving elements 27 by their extended ones Change training. For this purpose, it is expedient to releasably connect the lower area of the suction pipe end section 9, comprising the suction opening 16 and the driving elements 27, to the remaining part of the suction pipe end section 9 by means of a quick coupling. There is thus the advantageous possibility of using optimally effective driving elements 27 in adaptation to different operating conditions with a minimum of changeover times.

Wie in Fig. 3 ersichtlich, können Mitnahmeorgane 30 durch eine entsprechende Verformung von Abschnitten der Saugöffnung 16 gebildet werden. Diese Mitnahmeorgane 30 sind durch über die Saugebene nach unten vorragende Schaufeln 31 gebildet, deren in Drehrichtung (s. Pfeil) des Saugrohr-Endabschnittes 9 vorderen Endbereiche 32 weiter von der Längsachse 23 distanziert sind als die in Drehrichtung hinteren Bereiche 33. Durch diese eine turbinenschaufelartige Ebene höherer Ordnung bildenden Mitnahmeorgane 30 wird Schotter zur Verbesserung der Saugleistung in radialer Richtung nach innen zur Saugöffnung 16 bewegt.As can be seen in FIG. 3, entrainment members 30 can be formed by a corresponding deformation of sections of the suction opening 16. These entrainment members 30 are formed by blades 31 projecting downward over the suction plane, the front end regions 32 of which, in the direction of rotation (see arrow) of the end of the intake manifold 9, are further distanced from the longitudinal axis 23 than the rear regions 33 in the direction of rotation Driving elements 30 forming a higher-order plane, ballast is moved inward to the suction opening 16 in the radial direction in order to improve the suction power.

Bei der in Fig. 4 aufgezeigten Ausführungsvariante ist der SaugrohrEndabschnitt 9 als drehbar am Saugrohr 10 gelagerter Ring 43 ausgebildet, an dem die fingerförmigen Mitnahmeorgane 27 lösbar befestigt sind. Die Rotation des Ringes 43 um die Längsachse 23 wird durch eine mit dem Drehantrieb 26 verbundene Antriebsstange 44 und einem Antriebsritzel 25 erzielt.In the embodiment shown in FIG. 4, the suction pipe end section 9 is designed as a ring 43 rotatably mounted on the suction pipe 10, to which the finger-shaped entrainment members 27 are detachably fastened. The rotation of the ring 43 about the longitudinal axis 23 is achieved by a drive rod 44 connected to the rotary drive 26 and a drive pinion 25.

Fig. 5 zeigt eine Seitenansicht eines Saugrohr-Endabschnittes 9, wobei sich der die Saugöffnung 16 bildende Bereich in einer durch strichpunktierte Linien dargestellten Saugöffnungs-Ebene 34 befindet. Diese schließt mit der Längsachse 23 des Saugrohr-Endabschnittes 9 einen Winkel α ein. Dieser beträgt vorzugsweise 45°, kann jedoch in Abhängigkeit von der gewünschten Größe der Saugöffnung 16 zweckmäßigerweise zwischen etwa 30° und 50° variieren. Um die ellipsenförmige Saugöffnung 16 sind zahnförmig abstehende Mitnahmeorgane 27 verteilt. Durch die Schräglage der Saugöffnung 16 ist insbesondere in Verbindung mit der Drehung des Saugrohr-Endabschnittes 9 um die Längsachse 23 ein verbesserter Effekt zur Absaugung des Schotters auch unterhalb der Schwellen erzielbar.FIG. 5 shows a side view of a suction pipe end section 9, the area forming the suction opening 16 being located in a suction opening plane 34 shown by dash-dotted lines. This includes an angle α with the longitudinal axis 23 of the intake pipe end section 9. This is preferably 45 °, but can advantageously vary between approximately 30 ° and 50 ° depending on the desired size of the suction opening 16. Tooth-shaped entrainment members 27 are distributed around the elliptical suction opening 16. Due to the inclined position of the suction opening 16, in particular in connection with the rotation of the suction pipe end section 9 about the longitudinal axis 23, an improved effect for suctioning the ballast below the thresholds can also be achieved.

Die in Fig. 6 dargestellte weitere Variante eines Saugrohr-Endabschnittes weist ebenfalls eine schrägliegende Saugöffnung 16 auf, die durch eine Abwinkelung des unteren Endbereiches des Saugrohr-Endabschnittes 9 zustande kommt.The further variant of an intake manifold end section shown in FIG. 6 also has an inclined intake opening 16 which is caused by angling the lower end region of the intake manifold end section 9.

Die in Fig. 7 und 8 ersichtliche Variante zeigt einen Saugrohr-Endabschnitt 9 mit einem koaxial zu diesem angeordneten, im Querschnitt kreisförmigen Schubrohr 35, das durch einen schematisch angedeuteten Antrieb 36 mit Hilfe von Führungen 37 relativ zum Saugrohr-Endabschnitt 9 höhenverstellbar ausgebildet ist. Während der Saugrohr-Endabschnitt 9 eine schrägliegende erste Saugöffnung 16 gemäß Fig. 5 aufweist, ist das untere Ende des Schubrohres 35 mit einer zweiten Saugöffnung 38 ausgestattet. Diese liegt in einer senkrecht zur Längsachse 23 verlaufenden Saugöffnungs-Ebene 39. Mit dieser Variante besteht die Möglichkeit, wahlweise unter entsprechender Verschiebung des Schubrohres 35 entweder mit einer senkrecht zur Längsachse 23 verlaufenden Saugöffnung 38 (Fig. 7) oder mit einer schrägen Saugöffnung 16 (Fig. 8) abzusaugen. In beiden Stellungen erfolgt mit Hilfe eines nicht näher dargestellten Drehantriebes eine kontinuierliche Rotation des Saugrohr-Endabschnittes 9 um die Längsachse 23.The variant shown in FIGS. 7 and 8 shows an intake manifold end section 9 with a thrust tube 35 which is arranged coaxially with it and is circular in cross section and which is designed to be height-adjustable relative to the intake manifold end section 9 by means of a schematically indicated drive 36 with the aid of guides 37. While the suction pipe end section 9 has an inclined first suction opening 16 according to FIG. 5, the lower end of the push pipe 35 is equipped with a second suction opening 38. This lies in a suction opening plane 39 running perpendicular to the longitudinal axis 23. With this variant, there is the possibility, either with a corresponding displacement of the push tube 35, either with a suction opening 38 running perpendicular to the longitudinal axis 23 (FIG. 7) or with an oblique suction opening 16 ( Fig. 8) to suction. In both positions, the intake manifold end section 9 is continuously rotated about the longitudinal axis 23 with the aid of a rotary drive (not shown in more detail).

Schließlich zeigen die Fig. 9 und 10 (Fig. 10 ist eine Ansicht des in Fig. 9 dargestellten Saugrohr-Endabschnittes 9 gemäß Pfeil VI) noch eine weitere Variante eines Saugrohr-Endabschnittes 9. Dieser weist eine aus zwei Bereichen 40,41 bestehende Saugöffnung 16 auf. Der erste Bereich 40 der Saugöffnung 16 umfaßt den in der Saugöffnungs-Ebene 34 befindlichen, schrägliegenden Teil, während der zweite, die Saugöffnungs-Ebene 39 bildende Bereich 41 senkrecht zur Längsachse 23 verläuft. In diesem zweiten Bereich 41, welcher ungefähr ein Viertel des Kreisumfanges des Saugrohr-Endabschnittes 9 umfaßt, sind Ausnehmungen 42 am Saugrohr-Endabschnitt 9 vorgesehen, welche zahnförmige Mitnahmeorgane 27 bilden.Finally, FIGS. 9 and 10 (FIG. 10 is a view of the intake pipe end section 9 shown in FIG. 9 according to arrow VI) show yet another variant of an intake pipe end section 9. This has an intake opening consisting of two regions 40, 41 16 on. The first region 40 of the suction opening 16 comprises the inclined part located in the suction opening plane 34, while the second region 41 forming the suction opening plane 39 runs perpendicular to the longitudinal axis 23. In this second area 41, which comprises approximately a quarter of the circumference of the intake pipe end section 9, recesses 42 are provided on the intake pipe end section 9, which form tooth-shaped entrainment members 27.
