Abstract

Tamping device comprises a shaft (2) and a plate (4) positioned on its lower end and having a lower edge (3) spaced by the shaft. Hard metal inserts (8) are arranged in the plate to form a part of the plate side surface. Preferred Features: Each hard metal insert is arranged parallel with its longitudinal axis with respect to the plate front side and the plate lower edge.

Description

Die Erfindung betrifft einen Stopfpickel für eine Stopfmaschine zum Unterstopfen von unterhalb eines Gleises befindlichem Schotter, bestehend aus einem Pickelschaft und einer an dessen unterem Ende positionierten, eine vom Pickelschaft distanzierte Plattenunterkante aufweisenden Pickelplatte, die in Richtung der Plattenunterkante voneinander distanzierte und normal zu dieser verlaufende Plattenseitenflächen aufweist, die jeweils eine Plattenvorderseite mit einer Plattenrückseite der Pickelplatte verbinden.The invention relates to a tamping pick for a tamping machine for tamping of gravel located below a track, consisting of a pick shaft and one positioned at its lower end, one pimple plate having a lower edge of the plate distant from the pimple shaft, the distance from each other towards the lower edge of the plate and normal to this has extending plate side surfaces, each having a plate front connect with a plate back of the pimple plate.

Durch US 5 261 763 ist ein derartiger Stopfpickel bereits bekannt, wobei zur Optimierung der Abriebfestigkeit sowohl auf der Pickelplatte als auch am unteren Ende des Pickelschaftes Hartmetallplatten befestigt sind.Such a tamping pick is already known from US Pat. No. 5,261,763 Optimization of the abrasion resistance both on the pimple plate and on the lower one Carbide plates are attached to the end of the pick shaft.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Stopfpickels der gattungsgemäßen Art, mit dem eine verbesserte Abriebfestigkeit erzielbar ist.The object of the present invention is to create a Darning pimples of the generic type, with an improved abrasion resistance is achievable.

Erfindungsgemäß wird diese Aufgabe mit einem Stopfpickel der eingangs genannten Art dadurch gelöst, daß in der Pickelplatte zylinderförmige Hartmetalleinlagen angeordnet sind, die jeweils mit einer Begrenzungsfläche einen Teil der Plattenseitenfläche bilden.According to the invention, this object is achieved with a tamping pick at the beginning mentioned type solved in that in the pimple plate cylindrical hard metal inserts are arranged, each with a boundary surface Form part of the plate side surface.

Diese Hartmetalleinlagen sind in entsprechenden Bohrungen der Pickelplatte sicher verankerbar, sodaß die im Bereich der schmalen Seitenflächen der Pickelplatte besonders hohen Krafteinwirkungen kein Abbrechen der Einlagen bewirken.These hard metal inserts are in corresponding holes in the pimple plate securely anchored, so that in the area of the narrow side surfaces Pimple plate particularly high forces no deposits break off cause.

Weitere Vorteile und Ausbildungen der Erfindung ergeben sich aus den Unteransprüchen und der Zeichnung. Further advantages and developments of the invention result from the subclaims and the drawing.

Im folgenden wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben.The invention is illustrated below with reference to the drawing Embodiments described in more detail.

weitere Varianten von Stopfpickeln.other variants of tamping picks.

Die in den Fig. 1 bis 5 dargestellten Stopfpickeln 1 setzen sich je aus einem Pickelschaft 2 mit einer an dessen unterem Ende befestigten, eine Plattenunterkante 3 aufweisenden Pickelplatte 4 zusammen. Dieser ist eine Plattenvorderseite 5 und eine parallel dazu verlaufende Plattenrückseite 6 zugeordnet. Seitlich ist jede Pickelplatte 4 durch Plattenseitenflächen 7 begrenzt, die die Plattenvorderseite 5 mit der Plattenrückseite 6 verbinden und normal zur Plattenunterkante 3 verlaufen.The tamping picks 1 shown in FIGS. 1 to 5 are each composed of one Pick shaft 2 with a lower edge fixed to its lower end 3 having pimple plate 4 together. This is a front panel 5 and a parallel to the back of the plate 6 assigned. Each pimple plate 4 is laterally delimited by plate side surfaces 7 which connect the plate front 5 to the plate back 6 and normal to Lower edge of plate 3 run.

Wie insbesondere in Fig. 2 ersichtlich, sind im Bereich der Plattenseitenflächen 7 zylinderförmige Hartmetalleinlagen 8 vorgesehen, die in entsprechenden Bohrungen 9 der Pickelplatte 4 positioniert sind. Jede dieser Hartmetalleinlagen 8 ist bezüglich einer Längsachse 10 parallel zur Plattenvorderseite 5 sowie zur Plattenunterkante 3 angeordnet und bildet mit einer kreisförmigen Begrenzungsfläche 11 einen Teil der Plattenseitenfläche 7. An jeder Plattenseitenfläche 7 sind drei Hartmetalleinlagen 8 übereinander und parallel zur Plattenvorderseite 5 vorgesehen. Sowohl die Plattenvorderseite 5 als auch die Plattenrückseite 6 ist durch Hartmetallplättchen 12 bedeckt.As can be seen in particular in FIG. 2, are in the area of the plate side surfaces 7 cylindrical hard metal inserts 8 are provided, which in corresponding Bores 9 of the pick plate 4 are positioned. Each of these hard metal inserts 8 is parallel to the front side 5 of the plate with respect to a longitudinal axis 10 and arranged to the lower edge 3 of the plate and forms with a circular Boundary surface 11 a part of the plate side surface 7. On each plate side surface 7 are three hard metal inserts 8 one above the other and parallel to Plate front 5 provided. Both the plate front 5 and the back of the plate 6 is covered by hard metal plates 12.

Wie in Fig. 5 ersichtlich, sind wahlweise auch zwei Reihen von jeweils übereinander positionierten Hartmetalleinlagen 8 zwischen Plattenvorder- und Plattenrückseite 5,6 möglich. Diese Variante eignet sich besonders für großflächigere Plattenseitenflächen 7. Gemäß einer in Fig. 6 aufgezeigten Variante können die Hartmetalleinlagen 8 mit ihrer Längsachse 10 auch im Winkel zur Plattenunterkante 3 angeordnet sein. Außerdem können die Hartmetalleinlagen 8 auch zweckmäßigerweise mit ihrer Begrenzungsfläche 11 etwa 0.5 bis etwa 1.5 mm über eine durch die Plattenseitenfläche 7 der Pickelplatte 4 gebildete Ebene hinausragen.As can be seen in FIG. 5, two rows of one another are optionally also available positioned hard metal inserts 8 between the front and Back of plate 5.6 possible. This variant is particularly suitable for larger areas Panel side surfaces 7. According to a variant shown in FIG. 6 can the hard metal inserts 8 with their longitudinal axis 10 also at an angle be arranged to the lower edge 3 of the plate. In addition, the hard metal deposits 8 also expediently with its boundary surface 11 0.5 to about 1.5 mm over a through the plate side surface 7 of the pimple plate 4 protruding level formed.
