Description

Die Erfindung betrifft einen Stopfpickel für ein Stopfaggregat einer Stopfmaschine zum Unterstopfen von Schotter eines Gleises, mit einem Pickelschaft und einer Pickelplatte, die zwecks Erhöhung des Abriebwiderstandes eine mit einer Öffnung ausgestattete Plattenhülle aus verschleißfestem Material aufweist, sowie ein Verfahren zur Herstellung eines Stopfpickels.The invention relates to a tamping pick for a Stopfaggregat a tamping machine for clogging gravel of a track, with a pike shaft and a pimple plate, which for the purpose of increasing the abrasion resistance one equipped with an opening Plate cover made of wear-resistant material, and a method for producing a stuffed pot.

Gemäß US 4 996 925 ist ein Stopfpickel mit einer auf einen Pickelschaft aufsteckbaren und eine Pickelplatte bildenden Plattenhülle bekannt. Eine entsprechende Verbindung zwischen Plattenhülle und Pickelschaft wird durch Kompression einer Zwischenlage erreicht. Eine derartige Lösung hat den Nachteil, daß die Verbindung zwischen Pickelschaft und Plattenhülle ausschließlich von den Kompressionskräften abhängig ist.According to US Pat. No. 4,996,925, a tamping pick with a push-fit shaft can be attached and a pimple plate-forming disc case known. An appropriate connection between disk cover and pimpling shaft is made by compression of an intermediate layer reached. Such a solution has the disadvantage that the connection between Pickelschaft and plate cover exclusively from the compression forces is dependent.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Stopfpickels der gattungsgemäßen Art, der bei hoher Abriebfestigkeit einen dauerhafteren Einsatz ermöglicht.The object of the present invention is now to provide a stuffed peg the generic type, the high abrasion resistance a more durable use allows.

Erfindungsgemäß wird diese Aufgabe mit einem Stopfpickel der eingangs genannten Art dadurch gelöst, daß die Plattenhülle mit einer zur Verschweißung mit dem Pickelschaft geeigneten Kernmasse gefüllt und die derart gebildete Pickelplatte durch eine Schweißnaht mit dem Pickelschaft verbunden ist.According to the invention this object is achieved with a tamping pick of the aforementioned Art solved by the fact that the disk shell with a for welding to the Pickelschaft filled with suitable core mass and the pick plate formed in this way by a Weld seam is connected to the Pickelschaft.

Diese Lösung ist mit dem besonderen Vorteil verbunden, daß der Stopfpickel sowohl eine hohe Festigkeit als auch einen optimalen Abriebwiderstand aufweist. Außerdem kann die Plattenhülle in vorteilhafter Weise unter Vermeidung von stoßempfindlichen Massekonzentrationen in gleichmäßiger Dicke gegossen werden. Bei Erneuerung einer nach langem Einsatz unbrauchbar gewordenen Pickelplatte ergibt sich ein weiterer Vorteil dadurch, daß die gesamte Pickelplatte entlang der Schweißnaht vom Pickelschaft abgetrennt werden kann und somit dieser nach Anschweißung einer neuen Pickelplatte wieder verwendbar ist.This solution has the particular advantage that the tamping pommel both has a high strength as well as an optimal abrasion resistance. Furthermore The plate cover can advantageously avoid shock-sensitive Mass concentrations are poured in a uniform thickness. At renewal after a long use unusable pimple plate results in another Advantage in that the entire picking plate along the weld of Pickelschaft can be separated and thus this after welding a new pimple plate is reusable.

Weitere Vorteile und Ausbildungen der Erfindung ergeben sich aus den Unteransprüchen, den Verfahrensansprüchen und der Zeichnung.Further advantages and embodiments of the invention will become apparent from the dependent claims, the method claims and the drawing.

Im folgenden wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben.In the following the invention with reference to embodiments shown in the drawing described in more detail.

Eine in Fig. 1 ersichtliche Stopfmaschine 1 ist zwischen Fahrwerken 2 mit einem höhenverstellbaren Stopfaggregat 3 ausgestattet. Dieses weist Stopfpickel 4 zur Unterstopfung eines Gleises 5 auf.An apparent in Fig. 1 tamping machine 1 is between suspensions 2 with a height-adjustable Stopfaggregat 3 equipped. This has tamping 4 for constipation a track 5 on.

Wie aus den weiteren Figuren 2 bis 4 erkennbar, weist der Stopfpickel 4 eine Pickelplatte 6 auf, die mit einem unteren Ende 7 eines Pickelschaftes 8 verbunden ist. Um den Abriebwiderstand der Pickelplatte 6 zu erhöhen, setzt sich diese aus einer Plattenhülle 9 und einer in diese eingegossenen Kernmasse 10 zusammen, deren Schweißkennlinie jener des Pickelschaftes 8 entspricht.As can be seen from the further FIGS. 2 to 4, the tamping pick 4 has a picking plate 6, which is connected to a lower end 7 of a Pickelschaftes 8. Around To increase the abrasion resistance of the picking plate 6, this is composed of a disk shell 9 and a cast into this core mass 10 together, whose Weld characteristic corresponds to that of the pickle shaft 8.

Eine Öffnung 11 der Plattenhülle 9 weist an einer Rückseite 12 des Stopfpickels 4 eine in Richtung zu einer Pickelunterkante 13 führende Vertiefung 14 auf. Das untere Ende 7 des Pickelschaftes 8 ist in bezug auf die Vertiefung 14 bzw. eine durch die Kernmasse 10 gebildete Kontaktfläche 15 gegengleich ausgebildet und weist eine Kontaktfläche 16 auf.An opening 11 of the plate shell 9 has on a rear side 12 of the stuffing 4 a leading towards a pimple bottom edge 13 recess 14. The lower End 7 of the Pickelschaftes 8 is with respect to the recess 14 and a through the Nuclear material 10 formed contact surface 15 formed opposite and has a Contact surface 16 on.

Zur Herstellung des Stopfpickels 4 wird vorerst die Plattenhülle 9 aus verschleißfestem Stahl gegossen. Danach wird die Plattenhülle 9 unter Bildung der die Öffnung 11 verschließenden Kontaktfläche 15 mit der Kernmasse 10 aufgefüllt (s. Fig. 4). Die Pickelplatte 6 wird derart auf das untere Ende 7 des Pickelschaftes 8 geschoben, daß die beiden Kontaktflächen 15, 16 unmittelbar aneinander grenzend zu liegen kommen. Anschließend wird eine Randzone 17 der Kontaktfläche 15 mit einer Randzone 18 der Kontaktfläche 16 des Pickelschaftes 8 unter Bildung einer Schweißnaht 19 verschweißt.For the preparation of the stuffing 4, the plate sleeve 9 is made of wear-resistant Poured steel. Thereafter, the disc case 9 to form the opening 11th closing contact surface 15 filled with the core mass 10 (see Fig. 4). The Pickelplatte 6 is pushed onto the lower end 7 of the Pickelschaftes 8, that the two contact surfaces 15, 16 lie directly adjacent to each other come. Subsequently, an edge zone 17 of the contact surface 15 with a marginal zone 18 of the contact surface 16 of the pickle shaft 8 to form a weld 19 welded.

Bei einer in Fig. 5 ersichtlichen Variante der Pickelplatte 6 ist die Öffnung 11 auf eine der Pickelunterkante 13 gegenüberliegende Oberkante 20 der Plattenhülle 9 begrenzt und kreisförmig ausgebildet. Aus dieser Öffnung 11 ragt ein Schaftstummel 21 der in die Plattenhülle 9 eingegossenen Kernmasse 10 heraus. Der Schaftstummel 21 wird zur Bildung des Stopfpickels 4 mit einem im Querschnitt gleichen (nicht näher dargestellten) unteren Ende des Pickelschaftes 8 verschweißt.In an apparent in Fig. 5 variant of the picking plate 6, the opening 11 is a the Pickelunterkante 13 opposite upper edge 20 of the disk case 9 limited and circular. From this opening 11, a shaft stub 21 protrudes the poured into the disk shell 9 core mass 10 out. The stem stub 21 is used to form the stuffing pickle 4 with a cross-sectionally similar (not closer shown) welded to the lower end of the Pickelschaftes 8.
