Definitions
- the invention relates to a device for producing a slot by means of a drilling and / or milling tool, which is driven by a motor and moved along the intended path of the slot.
- the invention relates to a device for producing a slot in rock, the slot in the manufacture of daytime in particular freezer or blind shafts and in the case of mining excavation of underground routes on the periphery of the same mostly to be made arcuate and the slot serves as a pressure transmission lock to prevent the spread of explosive vibrations in the surrounding mountains.
- Another option for producing slots in the rock is a chain slot saw type SB 1200/1300 developed by the BGR (Federal Institute for Geosciences and Natural Resources) in Hanover, but which is only able to produce straight slots.
- the cutting chain is guided on two guide tubes in circumferential bores. It is therefore not to be used for sawing horizontal or inclined to vertical arch slots (final report on the research project KWA 5103 0 of the BGR, Ref. 2.11 rock mechanics and building geology, archive no. 97 997).
- slot drilling Another method for slot drilling is known from patent P 30 40 057.
- the slots are produced by drilling a plurality of boreholes arranged next to one another, depending on the expansion of the slot.
- the ribs between the drill holes are very annoying when inserting finishing material. It is a process that is not suitable for the problems described and is also very uneconomical.
- the object on which the invention is based is to e.g. To expand the device so that with it also arch slots z. B. can be executed in rock as a milling aid or that it can be used in natural stone extraction.
- the slot produced by the device according to the invention in a manner which is gentle on the mountains by milling brings in particular the advantage of a smooth mountain surface, on which the mountain protection (expansion) in the form of masonry, steel arches with a delay or the like can be introduced close to the mountains.
- expensive backfill material shotcrete or the like
- the slot device is very suitable for producing arcuate slots, since the rotating and over the entire length with cutting or. Milling tools equipped hollow rods can also be guided on very small radii.
- Arch slits in the rock therefore consists of a hollow rod equipped with cutting or milling tools and a transport helix, which is pushed in by a drive unit in a rotational movement and by a lowering or feed device into the rock.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Herstellen eines Schlitzes mittels eines Bohr- und/oder Fräswerkzeuges, welches motorisch angetrieben und entlang der vorgesehenen Bahn des Schlitzes bewegt wird. Insbesondere betrifft die Erfindung eine Vorrichtung zum Herstellen eines Schlitzes in Gestein, wobei der Schlitz bei der Herstellung von Tages- insbesondere Gefrier- oder auch Blindschächten und bei bergmännischer Auffahrung von untertägigen Strecken an der Peripherie derselben meist bogenförmig herzustellen ist und der Schlitz hierbei als Druckübertragungssperre dient, um die Ausbreitung von Sprengerschütterungen in das umgebende Gebirge zu verhindern.The invention relates to a device for producing a slot by means of a drilling and / or milling tool, which is driven by a motor and moved along the intended path of the slot. In particular, the invention relates to a device for producing a slot in rock, the slot in the manufacture of daytime in particular freezer or blind shafts and in the case of mining excavation of underground routes on the periphery of the same mostly to be made arcuate and the slot serves as a pressure transmission lock to prevent the spread of explosive vibrations in the surrounding mountains.
Erschütterungsübertragungen in das umgebende Gebirge führen derzeit insbesondere bei dem Teufen von Gefrierschächten zu Beschädigungen an Gefrierrohren. Bei der Auffahrung von Blindschächten sowie Strecken und Tunneln mit Bohr- und Sprengarbeit wird das Gestein am Umfang derselben so stark zerrüttet, daß durch unbeabsichtigte Mehrausbrüche und Gesteinsnachfall erhebliche Behinderungen und wirtschaftliche Nachteile bei der Sicherung des Gebirges auftreten können.Vibration transmissions into the surrounding mountains currently lead to damage to the freezer pipes, particularly when freezing shafts are sunk. When blind shafts, as well as lines and tunnels with drilling and blasting work are excavated, the rock on the circumference of the rock is destroyed so severely that unintentional additional outbreaks and rock fall can cause considerable disabilities and economic disadvantages in securing the mountains.
Nach dem heutigen Stand der Technik ist die Herstellung von Schlitzen, z. B. in einem Schacht, nur mit Hilfe einer Kettenschrämmaschine mit Schrämarm möglich. Entwickelt wurden solche Machinen aus den bewährten Steinschrämmaschinen für einen Schacht mit ca. 10 m Durchmesser. Sie ist an einer Schienenführung zwangsgeführt. Wegen der umlaufenden Schrämkette muß jedoch das Schrämschwert eine Mindestbreite haben und kann deshalb z. B. zum Schneiden kleinerer Kreisbögen nicht eingesetzt werden. Diese Säge ist deshalb nicht für den Einsatz in Streckenvortrieben zum Schneiden von Umfangsschlitzen mit unterschiedlichen Bogenradien an Firste und Stößen geeignet. Ein weiterer Nachteil besteht darin, daß das Sägeblatt durch seine flache und verhältnismäßig breite Bauweise dazu neigt, in tangentialer Richtung zu schneiden und auszuweichen, wodurch bei der Zwangsführung auf einem Bogen eine gewisse Neigung zum Verklemmen gegeben ist (Firmenprospekt über "Steinschrämmaschinen" der Firma Maschinenfabrik Korfmann Typ ST 50S).According to the current state of the art, the production of slots, e.g. B. in a shaft, only possible with the help of a chain cutter with cutter arm. Such machines were developed from the proven stone cutting machines for a shaft with a diameter of approx. 10 m. It is positively guided on a rail guide. Because of the circumferential cutting chain, the cutting sword must have a minimum width and can therefore z. B. for cutting smaller arcs. This saw is therefore not for Suitable for use in track drives for cutting circumferential slots with different arc radii on ridges and joints. Another disadvantage is that the saw blade, due to its flat and relatively wide construction, tends to cut and dodge in the tangential direction, so that there is a certain tendency to jam in the case of forced guidance on an arch (company brochure about "stone cutting machines" from Maschinenfabrik Korfmann type ST 50S).
Eine weitere Möglichkeit zur Herstellung von Schlitzen im Gestein bietet eine von der BGR (Bundesanstalt für Geowissenschaften und Rohstoffe) in Hannover entwickelte Kettenschlitzsäge Typ SB 1200/1300, die jedoch nur in der Lage ist, gerade Schlitze herzustellen. Die Schneidekette wird hierbei an zwei Führungsrohren in vorab hergestellten Bohrungen umlaufend geführt. Sie ist deshalb für das Sägen horizontaler oder geneigter bis vertikaler Bogenschlitze nicht einzusetzen (Schlußbericht zum Forschungsvorhaben KWA 5103 0 der BGR, Ref. 2.11-Felsmechanik und Baugeologie, Archiv- Nr. 97 997).Another option for producing slots in the rock is a chain slot saw type SB 1200/1300 developed by the BGR (Federal Institute for Geosciences and Natural Resources) in Hanover, but which is only able to produce straight slots. The cutting chain is guided on two guide tubes in circumferential bores. It is therefore not to be used for sawing horizontal or inclined to vertical arch slots (final report on the research project KWA 5103 0 of the BGR, Ref. 2.11 rock mechanics and building geology, archive no. 97 997).
Weitere Machinen zur Herstellung von geraden Schlitzen, insbesondere für das Unterschneiden von Kohle und anderem Gestein sind von Fa. Eickhoff, Bochum (bis ca. 1975) sowie Fa. Joy, Mashinery Company, Pittsburg/USA bekannt. Wegen ihrer Zwangsführung an Panzerförderern bzw. an Fahrladern sind sie für die geschilderten Zwecke nicht einsetzbar. (Sonderabdruck aus der "Montan- Zeitung" Nr. 12, Dez. 1951 und 2. Joy Manufacturing Company, Pittsburg, Bulletin No. C 74, M-40 706).Other machines for the production of straight slots, in particular for the undercutting of coal and other rock, are known from Eickhoff, Bochum (until about 1975) and from Joy, Mashinery Company, Pittsburg / USA. Because of their forced guidance on tank conveyors or on loaders, they cannot be used for the purposes described. (Special reprint from "Montan- Zeitung" No. 12, Dec. 1951 and 2. Joy Manufacturing Company, Pittsburg, Bulletin No. C 74, M-40 706).
Weitere Geräte zur Schlitzherstellung für das Unterschneiden von Kohle sind bekannt (P32 36 994.8- 24 sowie P22 46 233.5). Auch diese Geräte werden an Zugmitteln gezogen und sind nicht für das Herstellen von den eingangs genannten Schlitzen in Schächten, Strecken usw. geeignet.Other devices for slot production for undercutting coal are known (P32 36 994.8-24 and P22 46 233.5). These devices are also pulled by traction devices and are not suitable for making the slots in shafts, lines, etc. mentioned at the beginning.
Ein weiteres Verfahren zum Schlitzbohren ist bekannt durch das Patent P 30 40 057. Hierbei erfolgt das Herstellen der Schlitze durch Bohren einer Vielzahl nebeneinander angeordneter Bohrlöcher, je nach Ausdehnung des Schlitzes. Die zwischen den Bohrlöchern anstehenden Rippen sind sehr störend beim Einbringen von Ausbaumaterial. Es ist ein Verfahren, welches für die geschilderte Problematik nicht geeignet und außerdem sehr unwirtschaftlich ist.Another method for slot drilling is known from patent P 30 40 057. Here, the slots are produced by drilling a plurality of boreholes arranged next to one another, depending on the expansion of the slot. The ribs between the drill holes are very annoying when inserting finishing material. It is a process that is not suitable for the problems described and is also very uneconomical.
Die der Erfindung zugrundeliegende Aufgabe besteht darin, die e.g. Vorrichtung derart auszubauen, daß mit ihr auch Bogenschlitze z. B. in Gestein als Fräsehilfe ausgeführt werden können oder daß sie bei der Natursteingewinnung einsetzbar ist.The object on which the invention is based is to e.g. To expand the device so that with it also arch slots z. B. can be executed in rock as a milling aid or that it can be used in natural stone extraction.
Die Lösung ist in den kennzeichnenden Merkmalen des Anspruches 1 beschrieben.The solution is described in the characterizing features of
Die übrigen Ansprüche stellen vorteilhafte Weiterbildungen der Erfindung dar.The remaining claims represent advantageous developments of the invention.
Der mittels der erfindungsgemäßen Vorrichtung gebirgsschonend durch Fräsen hergestellte Schlitz bringt insbesondere den Vorteil einer glatten Gebirgsoberfläche, an der die Gebirgssicherung (Ausbau) in Form von Mauerwerk, Stahlbögen mit Verzug o.a. dicht an das Gebirge eingebracht werden kann. Durch die Vermeidung von unbeabsichtigtem Mehrausbruch kann auf das Einbringen von teurem Hinterfüllmaterial (Spritzbeton o.a.) verzichtet werden. Bei der Gewinnung von Naturstein in Form von kantigen, insbesondere gerundeten Blöcken ist die Schlitzvorrichtung zur Herstellung bogenförmiger Schlitze sehr geeignet, da das rotierende und über die ganze Länge mit Schneidbzw. Fräsenwerkzeugen bestückte Hohlgestänge auch auf sehr kleinen Radien geführt werden kann.The slot produced by the device according to the invention in a manner which is gentle on the mountains by milling brings in particular the advantage of a smooth mountain surface, on which the mountain protection (expansion) in the form of masonry, steel arches with a delay or the like can be introduced close to the mountains. By avoiding unintentional additional outbreaks, expensive backfill material (shotcrete or the like) can be dispensed with. In the extraction of natural stone in the form of angular, in particular rounded blocks, the slot device is very suitable for producing arcuate slots, since the rotating and over the entire length with cutting or. Milling tools equipped hollow rods can also be guided on very small radii.
Die erfindungsgemäße Vorrichtung zum Herstellen von Schlitzen, z. B. Bogenschlitzen im Gestein besteht demnach aus einem mit Schneid- bzw. Fräswerkzeugen und einer Transportwendel bestückten Hohlgestänge, welches durch ein Antriebsaggregat in Rotationsbewegung und durch eine Senk- bzw. Vorschubeinrichtung in das Gestein eingestoßen wird. Mittels einer Führungseinrichtung wird das Gestänge wahlweise parallel zu dieser oder um diese auf einer beliebigen Bahn bewegt und fräst somit den gewünschten Schlitz aus. Die Herstellung von Bogenschlitzen ist somit problemlos möglich. Das gelöste Bohr- bzw. Schrämgut wird mechanisch oder mittels eines Spülmediums durch eine Spülvorrichtung entfernt. Es können senkrechte bis horizontale Schlitze hergestellt werden.The inventive device for producing slots, for. B. Arch slits in the rock therefore consists of a hollow rod equipped with cutting or milling tools and a transport helix, which is pushed in by a drive unit in a rotational movement and by a lowering or feed device into the rock. The linkage is moved either parallel to it or around it on any path by means of a guide device and thus mills out the desired slot. The production of arch slits is therefore possible without any problems. The loosened drilling or cutting material is removed mechanically or by means of a flushing medium through a flushing device. Vertical to horizontal slots can be made.
Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels mittels der Fig. 1 und 2 näher erläutert.The invention is explained below with reference to an embodiment using FIGS. 1 and 2.
Die gemäß Figur 1 dargestellte Vorrichtung besteht aus einem Trägerkörper 1 in Form eines Hohlgestänges mit außenliegender Transportwendel 2, die auf dem Wendelfuß und der Wendelaußenseite mit Schneid bzw. Fräswerkzeugen 3 vollständig oder zumindest im vorderen Bereich 14 (wie dargestellt) und auf der konischen Stirnseite 19 bestückt ist. Der Trägerkörper 1 kann hierzu aus zwei (oder mehreren) Teilen 13, 14 hergestellt sein, die biegefest an der Nahtstelle 11 miteinander verschraubt sind.The device shown in FIG. 1 consists of a
Mit Hilfe des Antriebes 4 und einer Senk- oder Vorschubeinrichtung 5 wird die Bohr- und Frässpindel 1 - 2 über die Antriebswelle 15 bzw. das Gestänge 20 z. B. an der Schacht- bzw. Streckenperipherie 17 (s. Figur 2) in das Gebirge 16 eingestochen. Dabei wird das Bohrklein über die Wendel 2 ausgetragen und bei senkrecht nach unten gerichteter Vorschubrichtung am Bohrlochmund abgesaugt.With the help of the
Das Hohlgestänge 1 für die Schlitzherstellung wird auf dem Schacht- oder Streckenumfang 17 mit der Führungseinrichtung 6, 6ʹ bewegt, wobei sich das Schneid- bzw. Fräsgestänge 1 - 3 mit einer an die Härte des Gesteins angepaßten Drehzahl und mit entsprechendem Andruck dreht. Eine Kühlung der Schneidbzw. Fräswerkzeuge 3 erfolgt mittels Flüssigkeits- oder Luftspülung über einen Spülkopf 7 an der Antriebswelle 15 und Leitungen 12 durch das Hohlgestänge mit nach außen gerichteten, im Abstand zueinander angeordneten Austrittsdüsen 8. Das in den Ringspalt 18 ausgeworfene Fräsgut wird mechanisch oder durch eine nachgeführte Absaugeinrichtung 9 (s. figur 2) entfernt. In besonderen Fällen kann das Schrämgut jedoch auch durch das Hohlgestänge über die Düsen 8, Leitung 12 und Spülkopf 7 abgesaugt werden.The
Die Vorrichtung hat den Vorteil, daß das Hohlgestänge 1 in rotierender Weise durch die Führungseinrichtung 6, 6ʹ bogenförmig, z. B. auf dem Schacht- bzw. Streckenumfang bewegt werden kann, wobei im Gebirge 16 der Ringspalt 18 hergestellt wird. Durch die Rotationsbewegung des Schneid- bzw. Fräsarmes ist ein Verklemmen beim Bogenschneiden nicht möglich. Das gelöste Schrämgut wird mechanisch oder durch eine Saugvorrichtung aus dem Ringspalt 18 entfernt, so daß damit beim Sprengen des inneren Schacht- oder Streckenkörpers eine direkte Druckwellenübertragung auf den außenliegenden Gebirgsmantel 16 nicht mehr erfolgen kann.The device has the advantage that the
Die Vorrichtung ist weiterhin durch die Fähigkeit, enge Bogenschlitze zu fräsen, vorteilhaft geeignet, Natursteine nicht nur als geradkantige Blöcke, sondern auch als zylinderförmige Blöcke herzustellen.The device is furthermore advantageously suitable due to the ability to mill narrow arch slots, not only to produce natural stones as straight-edged blocks, but also as cylindrical blocks.
