Beschreibung description
Es gibt Bohrsysteme/-werkzeuge, die Vorbohrungen von innen nach aussen erweitern - mit dem grossen Nachteil, dass vor oder-während des Er-weiterns ein Vorbohrloch erstellt werden muss. There are drilling systems / tools that extend pilot holes from the inside out - with the major disadvantage that a pilot hole must be drilled before or during the expansion.
Erfindungsgemäss arbeiten zum Bohren von Stollen, Tunnels und Schächten Rollen-, Disken oder Frässcheibenwerkzeuge von der Bohrlochmitte aus hinterschneidend nach aussen - konventionell oder aktiviert. Die entsprechenden hinterschneidenden Bohr-/Abtragwerkzeuge können radial - oder zuerst radial und dann linear - nach aussen bewegt werden zum Bohren beliebiger Durchmesser - und dabei an längenveränderlichen Armen sitzen, die an einem rotierend angetriebenen Grundkörper/Bohrkopf befestigt sind; Längenveränderlichkeit, um nicht nur kreisrund, sondern auch beliebige Profile und beliebige Durchmesser bohren zu können -u.a. Bogenprofile. Mindestens ein entsprechendes Bohrwerkzeug - vorzugsweise mehrere tragen hierbei schichtweise ab. Hierbei können auch mehrere Bohrwerkzeuge an einem Arm hintereinander Schicht für Schicht abtragen. According to the invention, for drilling tunnels, tunnels and shafts, roller, disc or milling disk tools undercut from the center of the borehole to the outside - conventional or activated. The corresponding undercutting drilling / removal tools can be moved radially - or first radially and then linearly - outwards for drilling any diameter - while sitting on arms which are variable in length and which are fastened to a rotatingly driven base body / drilling head; Variable length so that not only circular, but also any profile and diameter can be drilled - including Arch profiles. At least one corresponding drilling tool - preferably several wear away in layers. Here, several drilling tools can be removed layer by layer on one arm in a row.
Beim hinterschneidenden schichtweise Abtragen jedwede aktiviert schlagende Bohrwerkzeuge einzusetzen - bringen die erfinderischen Vorteile, dass die hierbei erforderlichen Andruck- und Energiekräfte bei weniger als 1/3 liegen, d.h. u.a., dass damit extrem leichte Maschinen, Halterungen etc. verwendet werden können - und angetriebene aktiviert schlagende Fräs-/Schneid-, insbesondere aber Rollenbohrwerkzeuge, keine Mindestfortbewegungsge-schwindigkeit mehr benötigen; d.h. diese können sogar auf der Stelle bohren - wichtig, um extreme Konturen/Profile auszuarbeiten. Dieser Nachteil soll mit der Erfindung gemäss dem Patentanspruch 7 behoben werden. Using any activated striking drilling tools when undercutting in layers removes the inventive advantages that the pressure and energy forces required are less than 1/3, i.e. Among other things, that extremely light machines, brackets, etc. can be used - and driven, activated, impacting milling / cutting tools, but especially roller drilling tools, no longer require a minimum speed of travel; i.e. these can even drill on the spot - important for working out extreme contours / profiles. This disadvantage is to be eliminated with the invention according to claim 7.
In den Zeichnungen, die nur Ausführungsbeispiele darstellen, ist in der Fig. 1 ein einseitig konisches Diskenrollenbohrwerkzeug gezeigt — konventionell oder aktiviert schlagend arbeitend - das um den hierbei stehenbleibenden Kern 5 rotiert. 2 ist in einer bevorzugten Ausführung ein längenveränderbarer Arm, der um den Drehpunkt 3 radial geschwenkt wird - bis zum Enddurchmesser eines beliebigen Profils. 4 ist der drehende angetriebene Bohrkopfgrundkörper, der mittig ein Werkzeug besitzt 6, um bei dieser Version den Kern 5 abzutragen - oder ein Loch 7 hat, in den der Kern hereinwachsen kann. 8 ist die Tunnelwandung. In the drawings, which only show exemplary embodiments, FIG. 1 shows a disc roller drilling tool which is conical on one side - working conventionally or in an activated manner - which rotates about the core 5 which remains here. In a preferred embodiment, 2 is an arm which can be changed in length and which is pivoted radially about the pivot point 3 - up to the final diameter of any profile. 4 is the rotating driven drill head body, which has a tool in the middle 6 to remove the core 5 in this version - or has a hole 7 into which the core can grow. 8 is the tunnel wall.
In Fig. 2 ist 9 ein vorzugsweise aktiviert schlagendes Rollen-, Scheiben- oder Fräswerkzeug dargestellt. 10 ist die Hinterschneidlinie, erfahrungsge-mäss mit einer Vorgabe von vielen Zentimetern in härtestem Gestein - 11 das Gebirge - der Gebirgs-druck hilft beim Abspalten. 12 ist ein Schiebe-A/er-schiebestück, um in der dargestellten Stellung des Armes bzw. Werkzeuges beliebige Konturen und Enddurchmesser bohren zu können. Die übrigen Aggregate etc. entsprechen denen in der Fig. 1. 2, a preferably activated beating roller, disc or milling tool is shown. 10 is the undercut line, according to experience with a specification of many centimeters in the hardest rock - 11 the mountains - the mountain pressure helps to split off. 12 is a sliding A / he sliding piece in order to be able to drill any contours and end diameters in the position of the arm or tool shown. The other units etc. correspond to those in FIG. 1.
