Als Vibrationserreger dient eine rotierbare Exzenterwelle, an der die Beistellantriebe zur Übertragung der Schwingungen auf die Stopfpickel angelenkt sind.  [02] Stopfaggregate to Unterstopfen thresholds of a track are already widely known, such. As by US 4,240,352, AT 339 358, EP 0 331 956 or US 4 068 595.

[06] Eine derartige konstruktive Ausführung einer Schwingungsübertragung auf die Stopfpickel hat den besonderen Vorteil, dass mit lediglich einem Vibrationserreger die Schwingungen über den Verbindungsträger auf wenigstens zwei Beistellantriebe übertragbar sind. Auf diese Weise kann die Anzahl der sehr hohen Belastungen ausgesetzten Vibrationserreger sowie der konstruk^ tive Aufwand reduziert werden. Außerdem ist eine exakte Schwingungssynchronisation erzielbar. Die Funktion der ebenfalls hohen Belastungen ausgesetzten Beistellantriebe kann auf die lineare Beistellbewegung für die Stopfbewegung der Stopfpickel beschränkt werden.  Such a structural design of a vibration transmission to the tamping picks has the particular advantage that with only one vibration exciter, the vibrations on the connection carrier on at least two Beistellantriebe be transferred. In this way, the number of very high loads exposed vibration exciter and the constructive effort can be reduced. In addition, an exact vibration synchronization can be achieved. The function of the also subject to high loads Beistellantriebe can be limited to the linear Beistellbewegung for the stuffing movement of the tamping pick.
[07] Weitere Vorteile der Erfindung ergeben sich aus den weiteren Ansprüchen und der Zeichnungsbeschreibung.  [07] Further advantages of the invention emerge from the further claims and the description of the drawings.
[08] Im Folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben. Es zeigen: Fig. 1 eine Seitenansicht eines Stopfaggregates zum gleichzeitigen Unterstopfen von zwei Schwellen eines Gleises, Fig. 2 eine Ansicht des Stopfaggregates gemäß Pfeil II in einer Schienenlängsrichtung, Fig. 3 bis 7 weitere Varianten eines erfindungsgemäßen Stopfaggregates.  [08] In the following the invention will be described in more detail with reference to an embodiment shown in the drawing. 1 shows a side view of a tamping unit for the simultaneous underfilling of two sleepers of a track, FIG. 2 shows a view of the tamping unit according to arrow II in a rail longitudinal direction, FIGS. 3 to 7 show further variants of a tamping unit according to the invention.
[09] Ein in Fig. 1 und 2 dargestelltes Stopfaggregat 1 zum gleichzeitigen Unterstopfen von zwei Schwellen 2 eines Gleises weist einen höhenverstellbar auf einem Aggregatrahmen 3 gelagerten, mit insgesamt vier hintereinander an- geordneten Stopfpickeln 4 verbundenen Pickelträger 5 auf. Die jeweils ein Stopfpickelpaar 6 bildenden Stopfpickel 4 sind auf dem Pickelträger 5 paarweise zueinander um eine Schwenkachse 9 verschwenkbar gelagert . Für diese Beistellbewegung (Pfeil 7) ist jeder Stopfpickel 4 mit einem hydraulischen Beistellantrieb 8 verbunden. Der Pickelträger 5 ist durch Antriebe 10 (Fig. 6) höhenverstellbar auf dem Aggregatrahmen 3 gelagert. [09] A tamping unit 1 shown in FIGS. 1 and 2 for simultaneous plugging of two sleepers 2 of a track has a height-adjustable mounted on an aggregate frame 3, with a total of four consecutively orderly stuffing 4 connected Pickelträger 5 on. The tamping picks 4 each forming a tufting pair 6 are pivotably mounted on the tine carrier 5 in pairs about a pivot axis 9. For this Beistellbewegung (arrow 7) each tamping 4 is connected to a hydraulic Beistellantrieb 8. The pimple carrier 5 is mounted in height-adjustable manner on the unit frame 3 by drives 10 (FIG. 6).
[10] Eigentlich ist jeder zum Eintauchen in Schotter des Gleises vorgesehener Actually, everyone is intended for immersion in gravel of the track
Stopfpickel 4 auf einem am Pickelträger 5 gelagerten und mit dem Beistellantrieb 8 verbundenen Stopfhebel 11 befestigt. Es wird jedoch für diese um die Schwenkachse 9 verschwenkbare Hebeleinheit im Folgenden der Einfachheit halber nur der Ausdruck„Stopfpickel" verwendet. Stopfpickel 4 mounted on a pimpled carrier 5 and connected to the Beistellantrieb 8 stuffing lever 11. However, for the sake of simplicity, only the term "tamping pick" is used for this lever unit, which can be pivoted about the pivot axis 9.
[11] Die insgesamt vier Beistellantriebe 8 beider Stopfpickelpaare 6 sind an einem gemeinsamen Verbindungsträger 12 angelenkt. Ein am Pickelträger 5 befestigter Vibrationserreger 13 ist mit dem Verbindungsträger 12 zur Übertragung von Stopfpickelschwingungen vom Verbindungsträger 12 auf die entsprechenden Beistellantriebe 8 und die angelenkten Stopfpickel 4 verbunden.  The total of four Beistellantriebe 8 both Stopfpickelpaare 6 are hinged to a common connection carrier 12. An attached to the pimple carrier 5 vibration exciter 13 is connected to the connection carrier 12 for transmitting Stopfpickelschwingungen from the connection carrier 12 to the corresponding Beistellantriebe 8 and the hinged tamping 4.
[12] Der hier etwa scheibenförmig ausgebildete Verbindungsträger 12 ist um eine parallel zu den Schwenkachsen 9 der Stopfpickel 4 verlaufende Drehachse 14 drehbar am Pickelträger 5 gelagert, und der als hydraulischer Linearmotor ausgebildete Vibrationserreger 13 ist für eine geringfügige zyklische Verdrehung bzw. Schwingung des Verbindungsträgers 12 um die Drehachse 14 vorgesehen. [13] Die durch den Vibrationserreger 13 erzeugte Schwingung des Verbindungsträgers 12 wird in weiterer Folge auf sämtliche angelenkten Beistellantriebe 8 und von diesen auf den jeweiligen Stopfpickel 4 (die ideale Stopfpickelfrequenz für die Unterstopfung beträgt 35 Hz) übertragen. Durch entsprechende Regelung/Steuerung des hydraulischen Vibrationserregers 13 können diverse Stopfparameter, wie die Schwingungsfrequenz, die Schwingungsamplitude sowie auch die Dauer der Schwingung, rasch verändert werden. Damit kann ein für die Unterstopfung der beiden Schwellen 2 vorgesehener Stopfzyklus optimal an die jeweiligen Schotterverhältnisse angepasst werden. Außerdem kann, wie durch die EP 1 653 003 bereits beschrieben, ein Stopfzyklus auch aus mehreren, jeweils unterschiedliche Stopfparameter aufweisenden Sequenzen zusammengesetzt sein. The here about disk-shaped connection carrier 12 is rotatably mounted about a parallel to the pivot axes 9 of the tamping 4 extending axis of rotation 14 on Pickelträger 5, and designed as a hydraulic linear motor vibration exciter 13 is for a slight cyclic rotation or vibration of the connecting member 12th provided about the rotation axis 14. [13] The vibration generated by the vibration exciter 13 of the connecting carrier 12 is subsequently transmitted to all articulated Beistellantriebe 8 and of these on the respective tamping pick 4 (the ideal stuffing tamping frequency for the Unterstopfung is 35 Hz). By appropriate regulation / control of the hydraulic vibration exciter 13, various stuffing parameters, such as the oscillation frequency, the oscillation amplitude as well as the duration of the oscillation, can be changed rapidly. This can be optimally adapted to the respective gravel conditions a provided for the Unterstopfung of the two thresholds 2 Stopfzyklus. In addition, as already described by EP 1 653 003, a stuffing cycle can also be composed of a plurality of sequences each having different stuffing parameters.
[14] Durch die erfindungsgemäße Zwischenschaltung eines Verbindungsträgers  [14] By the inventive interconnection of a connection carrier
12 zwischen Vibrationserreger 13 und den Beistellantrieben 8 kann eine wesentliche Vereinfachung des konstruktiven Aufwandes erreicht werden, da für vier Beistellantriebe 8 lediglich ein einziger Vibrationserreger 13 erforderlich ist. Außerdem ist durch eine entsprechende Positionierung der Anlenkpunkte der Beistellantriebe 8 am Verbindungsträger 12 eine exakte Synchronisierung der Stopfpickelschwingungen möglich.  12 between vibration exciter 13 and the Beistellantrieben 8, a significant simplification of the design effort can be achieved because only four single actuators 8 Vibrationserreger 13 is required for four Beistellantriebe. In addition, by an appropriate positioning of the articulation points of the auxiliary drives 8 on the connection carrier 12, an exact synchronization of Stopfpickelschwingungen possible.
[15] Wie in Fig. 2 ersichtlich, werden hier als Stopfpickel 4 eines Stopfaggregates  As seen in Fig. 2, are here as tamping 4 a tamping unit
1 immer die an einer Längsseite einer Schiene 15 eines Gleises eintauchbaren, auf einem Stopfpickelträger 12 gelagerten Stopfpickel 4 bezeichnet. Wie bereits vielfach bekannt, können die auf der anderen Längsseite der Schiene 15 eintauchbaren Stopfpickel 4 auf eigenen Pickelträgern 5 gelagert sein, so dass zwei unabhängig höhen- und querverschiebbare Stopfaggregate (Split-Head) vorliegen. Alternativ können jedoch diese beiden Stopfaggregate 1 auch zu einer einzigen Stopfeinheit verbunden sein. 1 always denoted on a longitudinal side of a rail 15 of a track, stored on a tamping pickup 12 stuffing 4. As already well known, those on the other long side of the Rail 15 submersible tamping 4 be mounted on own Pickelträgern 5, so that two independently height and transversely displaceable tamping units (split-head) are present. Alternatively, however, these two tamping units 1 may also be connected to a single tamping unit.
[16] Eine in Fig. 3 dargestellte Variante eines Stopfaggregates 1 unterscheidet sich hinsichtlich des soeben beschriebenen Stopfaggregates 1 dahingehend, dass der als hydraulischer Linearmotor ausgebildete Vibrationserreger 13 mittig zwischen den beiden zentralen, zum Eintauchen in ein gemeinsames Schwellenfach 16 vorgesehenen Stopfpickeln 4 mit einer parallel zu einer Höhenverstellrichtung des Stopfaggregates 1 verlaufenden Hubachse 17 angeordnet ist. A variant of a tamping unit 1 shown in Fig. 3 differs in terms of just described tamping unit 1 in that the designed as a hydraulic linear motor vibration exciter 13 centrally between the two central, provided for immersion in a common threshold compartment 16 stuffing 4 with a parallel is arranged to a height adjustment direction of Stopfaggregates 1 extending stroke 17.
[17] Der mit vier Beistellantrieben 8 verbundene Verbindungsträger 12 ist in einer am Pickelträger 5 befestigten Vertikalführung 18 in der Hubachse 17 relativ zum Pickelträger 5 verstellbar gelagert. Eine zyklische Schwingungsbewegung des Vibrationserregers 13 entlang der Hubachse 17 wird hier ebenfalls auf den Verbindungsträger 12 und von diesem auf die vier Beistellantriebe 8 und in weiterer Folge auf die Stopfpickel 4 übertragen.  [17] The connection carrier 12 connected to four auxiliary drives 8 is mounted so as to be adjustable relative to the pimple carrier 5 in a vertical guide 18 fastened to the pimpling carrier 5 in the lifting axis 17. A cyclical oscillation movement of the vibration exciter 13 along the lifting axis 17 is also transmitted here to the connection carrier 12 and from there to the four auxiliary drives 8 and subsequently to the tamping pimples 4.
[18] Ein in Fig. 4 zum Teil dargestelltes Stopfaggregat 1 weist zwei durch die Beistellantriebe 8 zueinander beistellbare Stopfpickel 4 zum Unterstopfen einer einzigen Schwelle auf. Der als hydraulischer Linearmotor ausgebildete und am Pickelträger 5 befestigte Vibrationserreger 13 ist mittig zwischen den beiden Stopfpickeln 4 des Stopfpickelpaares 6 mit einer parallel zu einer Höhenverstellrichtung des Stopf aggregates 1 verlaufenden Hubachse 17 ange- ordnet. Eine Längsachse 19 jedes Beistellantriebes 8 schließt mit der Hubachse 17 einen Winkel α von etwa 40 bis 50 Grad, vorzugsweise 45 Grad ein. [18] A tamping unit 1 shown in part in FIG. 4 has two tamping punches 4, which can be provided with each other by the auxiliary drives 8, for underfilling a single threshold. Designed as a hydraulic linear motor and attached to the pimple carrier 5 vibration exciter 13 is centered between the two stuffing tacks 4 of the tufting pair 6 with a parallel to a height adjustment of the tamping unit 1 extending Hubachse 17 ange- assigns. A longitudinal axis 19 of each Beistellantriebes 8 includes the lifting axis 17 at an angle α of about 40 to 50 degrees, preferably 45 degrees.
[19] Wie aus der schematischen Darstellung in Fig. 5 ersichtlich, könnte alternativ der Verbindungsträger 12 des zu Fig. 4 beschriebenen Stopfaggregates 1 auch um eine Drehachse 14 drehbar am Pickelträger 5 gelagert und mit dem Vibrationserreger 13 verbunden sein.  As can be seen from the schematic illustration in FIG. 5, alternatively, the connection carrier 12 of the tamping unit 1 described with reference to FIG. 4 could also be rotatably mounted on the tine carrier 5 about a rotation axis 14 and be connected to the vibration exciter 13.
[20] Ein in Fig. 6 schematisch dargestelltes Stopfaggregat 1 ist zum gleichzeitigen Unterstopfen von drei Schwellen 2 ausgebildet und setzt sich - in einer normal zur Schwenkachse 9 verlaufenden Richtung gesehen - aus zwei gleichartig ausgebildeten Stopfaggregatteilen 20 zusammen. Von diesen weist jeder drei Stopfpickel 4 auf, die an einem gemeinsamen Verbindungsträger 12 angelenkt sind. Jeder der beiden voneinander unabhängigen Verbindungsträger 12 ist jeweils um eine Drehachse 14 verdrehbar am jeweiligen Pickelträger 5 gelagert und mit einem Vibrationserreger 13 zur Erzeugung der Stopfpickelschwingungen verbunden. Im Falle eines Stopfhindernisses kann wahlweise lediglich der nicht über dem Hindernis befindliche Stopfaggregatteil 20 zum Unterstopfen abgesenkt werden. In diesem Fall würde der Vibrationserreger 13 des nicht abgesenkten Stopfaggregatteiles 20 außer Betrieb geschaltet sein, so dass keine Schwingungen erzeugt werden.  [20] A tamping unit 1 shown schematically in FIG. 6 is designed for the simultaneous underfilling of three sleepers 2 and is made up of two identically formed tamping unit parts 20, viewed in a direction normal to the pivot axis 9. Of these, each has three tamping pommel 4, which are hinged to a common connection carrier 12. Each of the two mutually independent connection carrier 12 is rotatably supported in each case about an axis of rotation 14 on the respective pickup carrier 5 and connected to a vibration exciter 13 for generating the Stopfpickelschwingungen. In the case of a stuffing obstacle, optionally, only the stuffing aggregate part 20 not located above the obstacle can be lowered for underfilling. In this case, the vibrator 13 of the non-lowered Stopfaggregatteiles 20 would be disabled, so that no vibrations are generated.
[21] In Fig. 7 ist ein prinzipiell bereits durch US 6 389 979 bekanntes Stopfaggregat 1 zum gleichzeitigen Unterstopfen von vier Schwellen 2 dargestellt. Dieses setzt sich - wie das zu Fig. 6 beschriebene Stopfaggregat 1 - aus zwei gleichartig ausgebildeten und hintereinander angeordneten Stopfaggregatteilen 20 zusammen. Allerdings befindet sich zwischen diesen ein dritter Stopfaggregatteil 20 mit zwei zum Eintauchen in dasselbe Schwellenfach 16 vorgesehenen Stopfpickeln. Erfindungsgemäß ist nun jeder der drei Stopfaggregatteile 20 ist mit einem um die Drehachse 14 verdrehbar am jeweiligen Pickelträger 5 gelagerten Verbindungsträger 12 ausgestattet, wobei jedem Verbindungsträger 12 ein eigener Vibrationserreger 13 zugeordnet ist. [21] FIG. 7 shows a tamping unit 1 which is already known in principle from US Pat. No. 6,389,979 for the simultaneous underfilling of four sleepers 2. This is - as the tamping unit 1 described for Fig. 6 - from two identically designed and successively arranged Stopfaggregatteilen 20 together. However, there is between these a third Stopfaggregatteil 20 with two provided for immersion in the same threshold compartment 16 stuffing pickles. According to the invention, each of the three stuffing assembly parts 20 is now equipped with a connection support 12 mounted rotatably about the rotation axis 14 on the respective pickup carrier 5, wherein each connection carrier 12 is assigned its own vibration exciter 13.
[22] Anstelle der beschriebenen hydraulischen Linearmotoren könnten die Vibrationserreger natürlich auch auf eine andere bekannte Art, z.B. elektrodynamisch, die auf den Verbindungsträger 12 bzw. die Stopfpickel einwirkenden Schwingungen erzeugen. [22] Instead of the hydraulic linear motors described, it should be understood that the vibration exciters could be used in any other known way, e.g. electrodynamically, which produce vibrations acting on the connection carrier 12 or the tamping picks.
