Description

Die Erfindung betrifft ein Stopfaggregat zum Unterstopfen von Schwellen eines Gleises, mit einem höhenverstellbar auf einem Aggregatrahmen gelagerten Pickelträger, auf dem jeweils durch einen hydraulischen, eine Zylinderachse aufweisenden und mit einem Vibrationserreger verbundenen Beistellantrieb zueinander verschwenkbare Stopfpickel gelagert sind.The invention relates to a Stopfaggregat for Unterstopfen thresholds of a track, with a height adjustable mounted on an aggregate frame pimple carrier, on each of which by a hydraulic, a cylinder axis and connected to a vibrating feeder Beistellantrieb are mounted to each other pivotable tamping.

Stopfaggregate zum Unterstopfen von Schwellen eines Gleises sind bereits vielfach bekannt, wie z. B. durch US 4 240 352 , AT 339 358 , EP 0 331 956 oder US 4 068 595 . Die auf die Stopfpickel einwirkenden Vibrationen des Vibrationserregers können entweder durch eine Exzenterwelle oder durch hydraulische Impulse in einem Linearantrieb erzeugt werden, der gleichzeitig auch die Beistellbewegungen der Stopfpickel ausführt.Stopfaggregate to Unterstopfen thresholds of a track are already widely known, such. B. by US 4,240,352 . AT 339,358 . EP 0 331 956 or US Pat. No. 4,068,595 , The vibrations of the vibration exciter acting on the tamping picks can be generated either by an eccentric shaft or by hydraulic impulses in a linear drive, which at the same time also carries out the auxiliary movements of the tamping picks.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Stopfaggregates der eingangs genannten Art, mit dem eine verbesserte Vibration der Stopfpickel möglich ist.The object of the present invention is now to provide a tamping unit of the type mentioned, with which an improved vibration of the tamping pick is possible.

Diese Aufgabe wird erfindungsgemäß mit einem Stopfaggregat der gattungsgemäßen Art durch die im Kennzeichen des Hauptanspruches angeführten Merkmale gelöst.This object is achieved with a tamping unit of the generic type by the features cited in the characterizing part of the main claim.

Ein derartiger Vibrationserreger auf hydraulischer Basis hat den Vorteil, dass funktionell eine klare Trennung zwischen der Vibrationserzeugung einerseits und der Beistellbewegung für die Stopfpickel andererseits erzielbar ist. Außerdem ist ein vereinfachter Steuerungsaufwand für die Vibrationserzeugung möglich.Such a vibration generator on a hydraulic basis has the advantage that functionally a clear separation between the vibration generation on the one hand and the Beistellbewegung for stuffing tamping on the other hand achievable is. In addition, a simplified control effort for vibration generation is possible.

Weitere Vorteile der Erfindung ergeben sich aus den Unteransprüchen und der Zeichnungsbeschreibung.Further advantages of the invention will become apparent from the dependent claims and the drawing description.

Im Folgenden wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben. Es zeigen: Fig. 1 eine Seitenansicht eines Beistellantriebe sowie Vibrationserreger aufweisenden Stopfaggregates, Fig. 2 bis 4 jeweils vereinfachte Darstellungen eines Vibrationserregers mit hydraulischem Schaltplan und Fig. 5 eine weitere Variante eines Beistellantriebes.In the following the invention will be described in more detail with reference to embodiments shown in the drawing. Show it: Fig. 1 a side view of a Beistellantriebe and vibration exciter tamping unit, Fig. 2 to 4 Simplified representations of a vibration exciter with hydraulic circuit diagram and Fig. 5 another variant of a Beistellantriebes.

Ein in Fig. 1 dargestelltes Stopfaggregat 1 zum Unterstopfen von Schwellen eines Gleises weist zwei Stopfpickel 2 auf, die jeweils mithilfe eines Beistellantriebes 3 für eine Schotterverdichtung zangenartig zueinander bewegbar sind. Jeder Stopfpickel 2 ist um eine Schwenkachse 4 verschwenkbar auf einem relativ zu einem Aggregatrahmen 5 höhenverstellbaren Pickelträger 6 gelagert. Jedem eine Zylinderachse 7 aufweisendem Beistellantrieb 3 ist ein hydraulisch basierter Vibrationserreger 8 zur Erzeugung von einer Beistellbewegung der Stopfpickel 2 überlagerten Vibrationen zugeordnet. Der Beistellantrieb 3 ist um eine Lagerachse 9 schwenkbar am Pickelträger 6 befestigt.An in Fig. 1 illustrated Stopfaggregat 1 for Unterstopfen thresholds of a track has two tamping pickles 2, which are each movable with the aid of a Beistellantriebes 3 for a ballast compaction to each other. Each tamping pick 2 is mounted pivotably about a pivot axis 4 on a pommel carrier 6, which is height-adjustable relative to an aggregate frame 5. Each a cylinder axis 7 having Beistellantrieb 3 is assigned a hydraulically based vibration exciter 8 for generating a Beistellbewegung the tamping 2 superimposed vibrations. The Beistellantrieb 3 is pivotally mounted about a bearing axis 9 on the pimple carrier 6.

Ein in Fig. 2 dargestellter Querschnitt des Beistellantriebes 3 zeigt einen zur Zylinderachse 7 koaxial angeordneten Innenzylinder 10 des Vibrationserregers 8, der in dieser speziellen Ausführungsvariante der Erfindung gleichzeitig auch als - aus Hydraulikzylinder und Zylinderkolben zusammengesetzter - Beistellantrieb 3 dient. Der Innenzylinder 10 (bzw. der Beistellantrieb 3) ist über Gleitflächen 11 in der Achsrichtung 7 verschiebbar in einem Außenzylinder 12 gelagert.An in Fig. 2 illustrated cross section of the Beistellantriebes 3 shows a cylinder axis 7 to the coaxially arranged inner cylinder 10 of the vibration exciter 8, which also serves in this particular embodiment of the invention as - composed of hydraulic cylinder and cylinder piston - Beistellantrieb 3. The inner cylinder 10 (or the auxiliary drive 3) is slidably mounted in an outer cylinder 12 via sliding surfaces 11 in the axial direction 7.

Zwischen zwei in Richtung der Zylinderachse 7 (Achsrichtung) voneinander distanzierten Gleitflächen 11 ist eine ringförmige Vertiefung 13 im Außenzylinder 12 vorgesehen. Ein diese ringförmige Vertiefung 13 in zwei - bezüglich der Achsrichtung 7 voneinander distanzierte - Fluidkanäle 14 unterteilender Distanzring 15 ist mit dem Innenzylinder 10 verbunden. Die beiden Fluidkanäle 14 sind für eine Vibrationserregung des Innenzylinders 10 (d.h. des Beistellantriebes 3) durch Versorgungsleitungen 16 abwechselnd hydraulisch beaufschlagbar (die für die Beistellbewegung des Beistellantriebes 3 erforderlichen Versorgungsleitungen sind der Einfachheit halber nicht dargestellt).Between two in the direction of the cylinder axis 7 (axial direction) spaced sliding surfaces 11 an annular recess 13 in the outer cylinder 12 is provided. A spacer ring 15 dividing this annular recess 13 into two fluid channels 14, which are spaced apart from one another with respect to the axial direction 7, is connected to the inner cylinder 10. The two fluid channels 14 are alternately hydraulically actuated by supply lines 16 for vibratory excitation of the inner cylinder 10 (i.e., the auxiliary drive 3) (the supply lines required for the auxiliary movement of the auxiliary drive 3 are not shown for the sake of simplicity).

Mit der angedeuteten Lagerachse 9 ist der Außenzylinder 12 des Vibrationserregers 8 direkt (und damit der Beistellantrieb 3 indirekt) am Pickelträger 6 angelenkt. Die abwechselnde Beaufschlagung der beiden je mit den Versorgungsleitungen 16 verbundenen Fluidkanäle 14 erfolgt durch eine um 180° phasenverschobene Doppelkolbenpumpe 17.With the indicated bearing axis 9 of the outer cylinder 12 of the vibration exciter 8 is directly (and thus the Beistellantrieb 3 indirectly) hinged to the pimple carrier 6. The alternating admission of the two each connected to the supply lines 16 fluid channels 14 is performed by a 180 ° out of phase double piston pump 17th

Eine Schwingungsamplitude der Stopfpickel 2 ist durch ein Hubvolumen H der Doppelkolbenpumpe 17 und das Volumen der beiden Fluidkanäle 14 definiert. Eine Änderung des Hubvolumens H ist durch eine Verstellung des Exzenterweges an der Doppelkolbenpumpe 17 möglich. Die Vibrations-Frequenz der Stopfpickel 2 entspricht der Hubfrequenz der Doppelkolbenpumpe 17 (bzw. Drehzahl n einer Exzenterwelle). Die VibrationsFrequenz ist durch Ändern der Exzenterwellen-Drehzahl von 0 bis 60 Hz einstellbar. Hub und Rückhub des Innenzylinders 10 (bzw. Beistellantriebes 3) erfolgt durch die 180° phasenverschobene Doppelkolbenpumpe 17. Die Schwingungsamplitude der Stopfpickel 2 als Funktion der Schlagkraft ist durch ein Proportional-Druckbegrenzungsventil 18 einstellbar. Durch dieses kann wahlweise auch die Stopfpickelvibration unterbrochen werden, ohne dafür den Antrieb der Doppelkolbenpumpe 17 abschalten zu müssen.A vibration amplitude of the tamping pick 2 is defined by a stroke volume H of the double-piston pump 17 and the volume of the two fluid channels 14. A change in the stroke volume H is possible by adjusting the Exzenterweges on the double piston pump 17. The vibration frequency of Stopfpickel 2 corresponds to the stroke frequency of the double piston pump 17 (or speed n of an eccentric shaft). The vibration frequency can be adjusted by changing the eccentric shaft speed from 0 to 60 Hz. Stroke and return stroke of the inner cylinder 10 (or Beistellantriebes 3) is effected by the 180 ° phase-shifted double piston pump 17. The oscillation amplitude of the tamping 2 as a function of impact force is adjustable by a proportional pressure relief valve 18. By this optionally also the stuffing picking vibration can be interrupted without having to switch off the drive of the double piston pump 17.

In der hier dargestellten Ausführungsvariante eines "Kombinationszylinders" lassen sich die Funktionen "Stopfpickelbeistellung" und "Stopfpickelvibration" in kompakter Bauweise sowie unter Einhaltung branchenüblicher Einbaumaße von Beistellzylindern in Stopfaggregaten problemlos vereinen.In the embodiment variant of a "combination cylinder" shown here, the functions "stuffing tip provision" and "stuffing pitch vibration" can be combined in a compact design as well as in compliance with industry standard installation dimensions of auxiliary cylinders in tamping units.

Der Außenzylinder 12 des Vibrationserregers 8 weist im Bereich der Gleitfläche 11 des Distanzringes 15 eine Auslaßöffnung 19 für aus den beiden Fluidkanälen 14 austretendes Lecköl auf, das über eine Speiseleitung 20 ergänzt wird. Damit kann das sich durch die Vibrationen intensiv erwärmende Öl laufend erneuert werden.The outer cylinder 12 of the vibration exciter 8 has in the region of the sliding surface 11 of the spacer ring 15 an outlet opening 19 for emerging from the two fluid channels 14 leak oil, which is supplemented via a feed line 20. Thus, the intensively heating oil can be continuously renewed by the vibrations.

Wie in einer durch Fig. 3 dargestellten Variante ersichtlich, sind die beiden einander zugekehrten Fluidkanäle 14 der beiden Vibrationserreger 8 einerseits und die beiden voneinander abgewandten Fluidkanäle 14 andererseits jeweils durch eine gemeinsame Versorgungsleitung 16 beaufschlagbar. Durch diese entsteht ein Druckausgleich zwischen den Vibrationsantrieben. Damit stellt sich die Vibrationsamplitude proportional zum Lastdruck (Vibrationswiderstand) ein. Folglich entsteht ein sogenanntes asynchrones Stopfen (mit dem Effekt, dass sich auf der Seite mit geringerem Vibrationswiderstand eine höhere Amplitude einstellt).Like in a through Fig. 3 shown variant, the two mutually facing fluid channels 14 of the two vibration exciter 8 on the one hand and the two fluid channels 14 facing away from each other on the other hand each acted upon by a common supply line 16. This creates a pressure balance between the vibratory drives. Thus, the vibration amplitude is proportional to the load pressure (vibration resistance). As a result, a so-called asynchronous plugging is produced (with the effect that a higher amplitude is established on the side with lower vibration resistance).

Gemäß einer in Fig. 4 ersichtlichen Ausführungsvariante ist von den beiden Versorgungsleitungen 16 des Vibrationserregers 8 eine durch die Doppelkolbenpumpe 17 und die andere je durch einen Hydraulikspeicher 21 beaufschlagbar. Diese als Membran- oder Kolbenspeicher ausgeführte hydraulische Feder ist über den Gasfüll- und Vorspanndruck definiert.According to a in Fig. 4 apparent variant of the two supply lines 16 of the vibration exciter 8 by the double piston pump 17 and the other each acted upon by a hydraulic accumulator 21. This designed as a diaphragm or piston accumulator hydraulic spring is defined by the gas filling and preload pressure.

Prinzipiell kann natürlich jede bekannte Art der Erzeugung eines pulsierenden Fluidstromes für den Vibrationserreger 8 verwendet werden. Es könnte z.B. anstelle der Kolbenpumpe ein vorzugsweise direkt am Vibrationserreger 8 befestigtes Proportionalventil vorgesehen werden.In principle, of course, any known type of generation of a pulsating fluid flow for the vibration exciter 8 can be used. It could e.g. Instead of the piston pump, a preferably directly attached to the vibration exciter 8 Proportional valve are provided.

Gemäß der in Fig. 5 dargestellten Variante ist der Distanzring 15 mit dem Außenzylinder 12 verbunden, während der Fluidkanal 14 im Innenzylinder 10 bzw. Beistellantrieb 3 vorgesehen ist.According to the in Fig. 5 the variant shown, the spacer ring 15 is connected to the outer cylinder 12, while the fluid channel 14 is provided in the inner cylinder 10 or Beistellantrieb 3.
