Abstract

The segments (2) of the cutting ring (1) are arranged in specific position on the roller basic body by means of a profile connection, e.g. a dovetail guide and adjustment springs. The segments of the cutting ring are connected with the roller basic body by screwable segment retainers. The segments can also be connected with the roller basic body by clamp nuts. The cutting components (3) are formed as chisels with a head and a shaft (11), the shaft being held in a recess (12) of the cutting ring, shaft and recess being provided with matching threads.

Description

Die Erfindung betrifft einen Rollenmeißel für Tunnelvortriebsmaschinen.The invention relates to a roller chisel for Tunnel boring machines.

Bekannte Tunnelvortriebsmaschinen sind mit Schneidköpfen und Rollenmeißeln bestückt, die mit Schneidringen versehen sind, welche aus einem Teil bestehen. Diese Schneidringe sind auf den Schneidkörper aufgepreßt oder aufgeschrumpft angeordnet und mittels Sicherungsring und Nut gesichert. Desweiteren sind Schneidrollen mit eingelöteten bzw. eingeschrumpften Hartmetallschneidstiften bekannt. Dabei können die Schneidringe und die mit Hartmetallstiften versehenen Schneidrollen unterschiedlichste Profile aufweisen.Known tunnel boring machines are with cutting heads and Roller chisels equipped with cutting rings, which consist of one part. These cutting rings are on the The cutting body is pressed on or shrunk on and by means of Circlip and groove secured. Furthermore, cutting rollers are included soldered or shrunk hard metal cutting pins known. You can use the cutting rings and those with carbide pins provided cutting rollers have a wide variety of profiles.

Von Nachteil bei diesen bekannten Ausführungsarten ist, daß die hierbei verwendeten, aus einem Teil bestehenden Schneidrollen im Falle einer notwendigen Reparatur immer komplett ausgewechselt werden müssen, auch wenn nur ein Teilbereich des Schneidringes betroffen ist. Das bedeutet, daß damit ein hoher Aufwand an Reparaturzeit, sowie ein materialtechnisch nicht vertretbarer Aufwand entsteht, da der Rollenmeißel aus dem Bohrkopf ausgebaut werden muß, um eine solche Reparatur durchführen zu können.A disadvantage of these known embodiments is that the used here, consisting of one part cutting rollers in If a repair is necessary, always replace it completely must be, even if only a portion of the cutting ring is affected. This means that a great deal of effort is involved Repair time, as well as a material technology  unreasonable effort arises because the roller chisel from the Drill head must be removed to carry out such a repair to be able to perform.

Der Erfindung liegt die Aufgabe zugrunde, einen Rollenmeißel für Tunnelvortriebsmaschinen zu schaffen, der die Nachteile der bekannten technischen Lösungen vermeidet.The invention has for its object a roller chisel for To create tunnel boring machines that have the disadvantages of the known avoids technical solutions.

Diese Aufgabe wird dadurch gelöst, daß die Meißel direkt in den Rollengrundkörper eingesetzt werden. Dabei sind verschiedene Möglichkeiten gegeben, z. B. das Einschrauben der Meißel in den Rollengrundkörper, das Verstiften der Meißel mit dem Rollengrundkörper und das Klemmen der Meißel. Dadurch ist es möglich, verschlissene Teile des Rollenmeißels auszutauschen, ohne die bisher nötige De- und Montage und den damit verbundenen Transportaufwand des kompletten Rollenmeißels aus dem Bohrkopf. Die gesamte Vortriebszeit wird durch die kürzeren Reparaturzeiten verkürzt und es ist möglich, die Meißel vor Ort auszuwechseln. This problem is solved in that the chisel directly in the Roller body are used. There are different ones Given opportunities, e.g. B. screwing the chisel into the Roller body, pinning the chisel with the Roller body and clamping the chisel. That’s it possible to replace worn parts of the roller chisel without the previously required disassembly and assembly and the associated Transport of the complete roller chisel from the drill head. The total tunneling time is due to the shorter repair times shortened and it is possible to change the chisel on site.  

Die Erfindung soll an einem Ausführungsbeispiel näher beschrieben werden. Die Zeichnungen zeigen inThe invention will be described in more detail using an exemplary embodiment become. The drawings show in

Fig. 1, die schematische Darstellung eines Rollengrundkörpers mit eingesetzten Meißeln, Fig. 1 is a schematic representation of a roller base body with inserted bits,

Fig. 2, einen Schnitt des Rollengrundkörpers nach Fig. 1. FIG. 2 shows a section of the roller base body according to FIG. 1.

An einem Rollengrundkörper 1 sind an dessen Umfang Aufnahmen 2 vorgesehen, in die Meißel 3 eingesetzt sind. Hierbei ist dies derart realisiert, daß im Rollengrundkörper 1, die Aufnahmen 2 konisch ausgestaltet sind, wobei die Meißel 3 mit dem passenden Konus versehen sind und die Meißel 3 durch das Einbringen in diese Aufnahme 2 geklemmt werden. Um im Falle einer Reparatur die Meißel 3, wegen des Austauschens vor Ort leicht lösen zu können, ist vorgesehen, daß quer zur Aufnahme 2, in deren unteren Bereich eintauchend eine Bohrung 4 angeordnet ist, über die mittels eines geeigneten Keilwerkzeuges ein Lösen des in der Aufnahme 2 geklemmten Meißels geklemmten Meißels 3 erfolgt.On a roller base body 1 , receptacles 2 are provided on its circumference, into which chisels 3 are inserted. This is realized in such a way that in the roller base body 1 , the receptacles 2 are designed conically, the chisels 3 being provided with the appropriate cone and the chisels 3 being clamped by being introduced into this receptacle 2 . In order to be able to solve the chisel 3 easily in the event of a repair because of the replacement on site, it is provided that a bore 4 is arranged transversely to the receptacle 2 , in the lower region of which a hole is immersed, by means of which a suitable wedge tool is used to release the in the Recording 2 clamped chisel clamped chisel 3 .

Ebenso ist es möglich, daß anstelle der hier beschriebenen Klemmung der Meißel 3 ein Einschrauben der Meißel in den Rollengrundkörper 1 erfolgen kann und damit ebenfalls ein Austauschen der Meißel vor Ort leicht möglich ist. Des weiteren ist es möglich, die Meißel 3 mit dem Rollengrundkörper 1 zu verbinden, indem in den Bereich der Aufnahmebohrung im Rollengrundkörper 1 eine Querbohrung eingebracht wird, und daß in diese Querbohrung ein Stift eingeschlagen wird, der mit einer im Meißel 3 vorhandenen Bohrung den Meißel 3 fest und sicher hält. It is also possible that instead of the clamping of the chisel 3 described here, the chisel can be screwed into the roller base body 1 and thus the chisel can also be easily replaced on site. Furthermore, it is possible to connect the chisel 3 with the roller base body 1 by introducing a transverse bore into the area of the receiving bore in the roller base body 1 , and in that a pin is driven into this cross bore, the pin having a bore in the bit 3 3 holds firmly and securely.
