Durch US 4 537 135 ist ein speziell zum Einsatz in Weichenabschnitten ausgebildetes Stopfaggregat bekannt, das jeweils pro Stopfwerkzeug zwei in Schwellenlängsrichtung nebeneinander angeordnete Stopfpickel zum Eintauchen in den Schotter aufweist. Jedem dieser beiden Stopfpickel ist ein eigener Schwenkantrieb zugeordnet, so daß zur Umgehung von verschiedenen Hindernissen in Weichenabschnitten eine optimale Anpassung der Stopfpickel durch seitliches Verschwenken möglich ist. Erforderlichenfalls können beide bzw. auch nur ein Stopfpickel in eine Außerbetriebstellung hochgeschwenkt werden.US Pat. No. 4,537,135 specifically designed for use in switch sections Stuffing unit known, the two per tamping tool Threshold picks arranged side by side for immersion in the gravel. Each of these two tamping axes is unique Swivel drive assigned so that to bypass various Obstacles in switch sections optimal adjustment of the tamping pick is possible by swiveling to the side. If necessary, you can both or just a tamping pick swung up into a non-operating position become.

Durch US 5 269 226 ist ein weiteres Stopfaggregat bekannt, bei dem ebenfalls pro Stopfwerkzeug zwei Stopfpickel in Schwellenlängsrichtung nebeneinander angeordnet sind. Während der der Schiene des zu unterstopfenden Gleises nähergelegene Stopfpickel starr mit dem Stopfwerkzeug verbunden ist, kann der benachbarte Stopfpickel durch einen Schwenkantrieb von einer ersten in eine zweite Arbeitsposition verschwenkt werden. Da beide Arbeitspositionen durch Anschläge genau definiert sind, erübrigt sich ein zeitaufwendiger Zentriervorgang durch die Bedienungsperson. Another tamping unit is known from US Pat. No. 5,269,226, in which likewise per tamping tool, two tamping picks side by side in the longitudinal direction of the sleeper are arranged. During that of the rail to be stuffed Nearby tamping ax rigidly connected to the tamping tool is, the adjacent tamping pimple by a swivel drive from one first swiveled into a second working position. Because both working positions are precisely defined by attacks, a time-consuming is unnecessary Centering process by the operator.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Stopfaggregates der gattungsgemäßen Art, bei dem die Stopfpickel besonders rasch für unterschiedliche Arbeitseinsätze verwendbar sind.The object of the present invention is to create a Tamping unit of the generic type, in which the tamping pick is particularly can be used quickly for different work assignments.

Durch diese spezielle Ausbildung des Schwenkantriebes besteht bei einem Minimum an konstruktivem Mehraufwand die Möglichkeit, den Stopfpickel rasch in verschiedene Arbeitspositionen zu verbringen. Damit erübrigt sich ein für die Bedienungsperson ermüdendes und zeitaufwendiges, wiederholtes Zentrieren des Stopfpickels vor jedem Stopfvorgang. Da die neue Arbeitsposition des Stopfpickels durch die Begrenzung des Kolbenhubes des Schwenk- und/oder Zusatzantriebes genau definiert ist, eignet sich die erfindungsgemäße Ausbildung vor allem für Gleisbereiche, in denen beispielsweise durch eine abschnittsweise vorhandene Leit- oder Schutzschiene wechselnde Stopfverhältnisse vorliegen und gegebenenfalls auch eine komplette Außerbetriebnahme eines Stopfpickels erforderlich ist.Due to this special design of the swivel drive there is one Minimum of additional constructive effort the possibility of the tamping pick to spend quickly in different working positions. So there is no need a tiring and time-consuming, repetitive one for the operator Center the tamping pick before each tamping process. Because the new working position of the tamping pimple by limiting the piston stroke of the Swivel and / or additional drive is precisely defined, the invention is suitable Training mainly for track areas in which, for example through a section-by-section guardrail or protective rail There are changing stuffing conditions and, if necessary, a complete one Decommissioning a tamping pick is required.

    Durch Einziehen der beiden Kolbenstangen 22 der beiden Zusatzantriebe 21 kann der verschwenkbar gelagerte Stopfpickel 8 sehr rasch von der ersten in eine zweite, in strichpunktierten Linien dargestellte Arbeitsposition verschwenkt werden. Diese Umstellung der Arbeitsposition ist vor allem dann sehr vorteilhaft, wenn abschnittsweise eine Hilfsschiene oder eine Weichenzunge vorliegt.By pulling in the two piston rods 22 of the two additional drives 21 can the swivel-mounted tamping pick 8 very quickly from the first pivoted into a second working position shown in dash-dotted lines become. This change of work position is especially then very advantageous if sections of an auxiliary rail or a switch tongue is present.

    Schließlich kann durch Einfahren der Kolbenstange 17 des Schwenkantriebes 16 der schwenkbar gelagerte Stopfpickel 8 auch in eine (in strichpunktierten Linien dargestellte) Außerbetriebstellung hochgeschwenkt werden. Dies ist vor allem dann zweckmäßig, wenn aus Platzgründen ein Eintauchen beider Stopfpickel 7,8 nicht möglich ist.Finally, by retracting the piston rod 17 of the swivel drive 16 of the swivel-mounted tamping pick 8 also in a (in dash-dotted lines Lines shown) can be swung up out of service. This is particularly useful if both of them are immersed for reasons of space Darning ax 7.8 is not possible.
