Abstract

A number of small roller boring tools (10) are radially mounted on a rotatably driven sleeve (6).

Description

Rollenbohrwerkzeuge für Bohrungen sowie zum Abtragen von Gestein, Mineralien und dgl. benötigen inzwischen ganz erhebliche Andruckkräfte bis zu 40 bis 50 Tonnen/Diske. Dies nicht zuletzt deshalb, weil die Durchmesser der Disken immer größer gewählt wurden, insbesondere aus lagertechnischen Gründen. Dabei wurde die am Gestein aufliegende Fläche immer größer und der spezifische Andruck immer geringer.Roller drilling tools for drilling and for removing rock, minerals and the like. now require very considerable pressure forces of up to 40 to 50 tons / disc. This not least because the diameters of the disks have always been chosen larger, especially for storage reasons. Thereby the one lying on the rock The area is getting bigger and the specific pressure is getting smaller.

Diese Erfindung geht den umgekehrten Weg d. h. unter Verwendung kleiner bis kleinster Rollenbohrwerkzeuge, die auf einer drehend angetriebenen Hülse in Abständen voneinander radial angeordnet sind - auswechselbar, erfindungsgemäß mit Schlagüberlagerung als Rollenmeißel.This invention goes the opposite way d. H. using small to smallest Roller drilling tools placed on a rotating driven sleeve at intervals are arranged radially from one another - interchangeable, according to the invention with Impact overlay as a roller chisel.

In der Fig. 1, nur einer Ausführungsart, sind (1) die einzelnen auf einer drehend angetriebenen Hülse (2) angeordneten konventionellen Rollenbohrwerkzeuge - vorzugsweise Disken zwei- oder einseitig konisch.In Fig. 1, only one embodiment, ( 1 ) the individual conventional roller boring tools arranged on a rotatingly driven sleeve ( 2 ) are preferably conical on two or one sides.

In der Fig. 2, einer spezifischen Schlagüberlagerungsbauart, ist (1) der Motor, (2) die von ihm schnelldrehend angetriebene Exzenterwelle, die in den Lagern (3) im Halter (4) gelagert ist. (5) ist ein Untersetzungsgetriebe für die langsam drehende Hülse (6), die über die Lager auf dem Exzenter (8) frei drehend gelagert ist. (9) sind die Gegengewichte, auf die die Anordnung und Massen der Rollenmeißel (10) abgestimmt sind, vorzugsweise dynamisch ausgewuchtet entsprechend der EP 91105564.8 respektive der EP 93116413.1.In Fig. 2, a specific type of impact superposition, ( 1 ) the motor, ( 2 ) the eccentric shaft driven by it at high speed, which is mounted in the bearings ( 3 ) in the holder ( 4 ). ( 5 ) is a reduction gear for the slowly rotating sleeve ( 6 ), which is freely rotating via the bearings on the eccentric ( 8 ). ( 9 ) the counterweights to which the arrangement and masses of the roller chisels ( 10 ) are matched are preferably dynamically balanced in accordance with EP 91105564.8 and EP 93116413.1.

In der Fig. 3 ist nur eine Reihe einseitig konischer Diskenrollenbohrwerkzeuge (12) angeordnet, die hier nur eine Schicht hinterschneidend abträgt.In Fig. 3 only a row of conical disc roller drilling tools ( 12 ) is arranged, which removes only one layer undercutting here.

In der Fig. 4 sind (13) mehrere gestuft spaltend angeordnete einseitig konische Diskenrollenbohrwerkzeuge, (14) ist der Grundkörper - ggf. mit der Schlagüberlagerung (15). Durch diese erfindungsgeinäße optimale Anordnung ist es möglich, die Löseleistung einer Walze mit Rollenbohrwerkzeugen extrem zu erhöhen, insbesondere beim Einsatz einer zentrischen Schlagüberlagerung, d. h. daß eben nicht jedes einzelne Rollenbohrwerkzeug aktiviert wird.In FIG. 4, (13) a plurality of stepped splitting arranged on one side conical Diskenrollenbohrwerkzeuge, (14) of the base body - if necessary with the impact overlay (15). This optimal arrangement according to the invention makes it possible to extremely increase the loosening capacity of a roller with roller drilling tools, in particular when using a centric impact overlay, ie that not every single roller drilling tool is activated.
