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 Schwellen längsrichtung 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 axes in the sleepers alongside each other 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 pivoted 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 special can be used quickly for different work assignments.

Erfindungsgemäß wird diese Aufgabe mit einem Stopfaggregat der eingangs beschriebenen Art dadurch gelöst, daß der Schwenkantrieb mit einem Zusatzantrieb verbunden und an einer der beiden Anlenkstellen angelenkt ist, während der Zusatzantrieb an der weiteren Anlenkstelle gelagert ist.According to the invention, this object is achieved with a tamping unit at the beginning described type solved in that the swivel drive with an additional drive connected and articulated at one of the two articulation points, while the additional drive is mounted at the other articulation point.

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 repetitive one that is tiring and time-consuming for the operator Center the tamping pick before each tamping process. Because the new working position the tamping pimple by limiting the piston stroke of the Swivel and / or additional drive is precisely defined, the invention is suitable Training especially for track areas in which, for example through a section-by-line guard rail or protective rail There are changing stuffing conditions and, if necessary, a complete one Decommissioning a tamping pick is required.
