Die Trägereinheit und die Bohreinheit sind über eine Anzahl von in Abteufrichtung arbeitenden Tragezylindern miteinander verbunden. Die Bohreinheit weist eine Anzahl von Verspannmodulen zum radialen sowie axialen Verspannen, eine Anzahl von in Abteufrichtung arbeitenden Verschiebezylindern und einen Bohrkopf auf, der mit den Verschiebezylindern verbunden und bei zum Verspannen aktivierten Verspannmodulen zum Vertiefen des Schachts eingerichtet ist. Weiterhin ist die gattungsgemäße Vorrichtung mit Sicherungsmodulen ausgestattet, die an der Trägereinheit angebracht und zum radialen sowie axialen Verspannen der Trägereinheit zeitweise im Wechsel mit dem Verspannen der Bohreinheit eingerichtet sind.

Die Tragezylinder sind vollständig ausgefahren, während die Verschiebezylinder eingefahren sind. Nach Inbetriebnahme des Bohrkopfes fahren die Verschiebezylinder maximal aus, bis die maximale Abteuftiefe während eines Abteufzyklus erreicht ist. Anschließend fahren die Verschiebezylinder vollständig ein und heben den Bohrkopf an. Dann werden die Sicherungsmodule deaktiviert und die Tragezylinder eingefahren, so dass sich die Trägereinheit absenkt, während die Bohreinheit weiterhin verspannt ist.

Fig. 1 zeigt in einer schematischen Seitenansicht ein Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung zum Abteufen eines Hauptschachts 1 als Schacht in einer im wesentlichen vertikal verlaufenden und der Richtung der Schwerkraft folgenden Abteufrichtung. Das Ausführungsbeispiel gemäß Fig. 1 verfügt über eine in Abteufrichtung rückseitig angeordnete Trägereinheit 2 und über eine in Abteufrichtung vorderseitig angeordnete Bohreinheit 3. Fig. 1 shows a schematic side view of an embodiment of an inventive device for sinking a main shaft 1 as a shaft in a substantially vertically extending and the direction of gravity following Abteufrichtung. The embodiment according to Fig. 1 has a support unit 2 which is arranged at the rear in the direction of lowering and via a drilling unit 3 arranged at the front in the direction of lowering.

Die Trägereinheit 2 weist eine Anzahl von Schachtbühnen 4, 5, 6, 7 auf, die sich radial über den größten Bereich des Querschnittes des Hauptschachtes 1 erstrecken und bei bestimmungsgemäßer Anordnung in dem Hauptschacht 1 in Abteufrichtung übereinander angeordnet sind. Zum Stabilisieren der Trägereinheit 2 in radialer Richtung sind Radialstabilisatoren 8 vorhanden. Eine Gruppe von Radialstabilisatoren 8 ist an der der Bohreinheit 3 nächstbenachbarten schachtsohlenseitigen Schachtbühne 4 angebracht. Eine weitere Gruppe von Radialstabilisatoren 8 ist an Verstrebungen 9 befestigt, die sich zwischen der der schachtsohlenseitigen Schachtbühne 4 am weitesten entfernt liegenden schachtmundseitigen Schachtbühne 7 und einer der schachtsohlenseitigen Schachtbühne 7 benachbarten zwischenliegenden Schachtbühne 6 erstrecken sowie mit diesen verbunden sind.The carrier unit 2 has a number of shaft platforms 4, 5, 6, 7, which extend radially over the largest region of the cross section of the main shaft 1 and are arranged one above the other in the direction of removal in the direction of removal when the device is arranged as intended. For stabilizing the carrier unit 2 in the radial direction radial stabilizers 8 are present. A group of radial stabilizers 8 are mounted on the shaft bottom side shaft platform 4 next to the drilling unit 3. Another group of radial stabilizers 8 is attached to struts 9, which extend between the bay bottom side shaft platform 4 furthest lying shaft mouth side shaft platform 7 and one of the shaft bottom side shaft platform 7 adjacent intermediate shaft platform 6 and are connected thereto.

Die Radialstabilisatoren 8 sind lediglich dazu eingerichtet, die Trägereinheit 2 gegen Bewegen in radialer Richtung spielfrei zu stabilisieren. Die Radialstabilisatoren 8 sind jedoch nicht dazu eingerichtet, die Trägereinheit 2 in dem Sinne in radialer und axialer Richtung des Hauptschachtes 1 zu verspannen, dass die Trägereinheit 2 während eines Betriebes der Bohreinheit 3 zum Abteufen des Hauptschachtes 1 die Bohreinheit 3 stabilisierende Kräfte in radialer und axialer Richtung aufnehmen kann.The radial stabilizers 8 are only adapted to stabilize the carrier unit 2 against movement in the radial direction without play. However, the radial stabilizers 8 are not adapted to brace the carrier unit 2 in the sense in the radial and axial direction of the main shaft 1 that the carrier unit 2 during operation of the drilling unit 3 for sinking the main shaft 1, the drilling unit 3 stabilizing forces in the radial and axial Can accommodate direction.

An der schachtbodenseitigen Schachtbühne 4 ist weiterhin eine Anzahl von Seilen 10 einer Hängeeinheit angebracht, die sich durch den Hauptschacht 1 von der Trägereinheit 2 weg erstrecken.On the shaft bottom side shaft platform 4, a number of ropes 10 a hanging unit is further attached, which extend through the main shaft 1 of the support unit 2 away.

An der der Bohreinheit 3 gegenüberliegenden schachtsohlenseitigen Schachtbühne 4 ist eine Anzahl von in Abteufrichtung arbeitenden Tragezylindern 11 angebracht, die sich von der schachtsohlenseitigen Schachtbühne 4 weg in Richtung der Bohreinheit 3 erstrecken und mit der Bohreinheit 3 verbunden sind.A number of carrying cylinders 11 operating in the lowering direction, which extend away from the shaft bottom side shaft platform 4 in the direction of the drilling unit 3 and are connected to the drilling unit 3, are mounted on the shaft bottom side shaft platform 4 opposite the drilling unit 3.

Die Bohreinheit 3 verfügt über einen Abstützrahmen 12, an dem zum einen die Tragezylinder 11 und zum anderen in Abteufrichtung arbeitende Verschiebezylinder 13 angebracht sind, die sich von der schachtsohlenseitigen Schachtbühne 7 weg in Richtung eines Bohrkopfes 14 der Bohreinheit 3 erstrecken und mit diesem verbunden sind.The drilling unit 3 has a support frame 12, to which on the one hand the support cylinder 11 and the other working in Abteufrichtung displacement cylinder 13 are mounted, which extend away from the shaft bottom side shaft platform 7 in the direction of a drill head 14 of the drilling unit 3 and are connected thereto.

Weiterhin lässt sich der Darstellung gemäß Fig. 1 entnehmen, dass die Bohreinheit 3 mit einer Anzahl von Verspannmodulen 15 ausgestattet ist, die an einer Bohrplattform 16 der Bohreinheit 3 angreifen und mit Verspannzylindern 17 ausgestattet sind, die sich in radialer Richtung erstrecken, radial innenseitig mit der Bohrplattform 16 verbunden und radial außenseitig mit Verspannplatten 18 versehen sind. Die Verspannmodule 15 sind dazu eingerichtet, die Bohreinheit 3 radial sowie axial derart zu verspannen, dass im wesentlichen sämtliche während des Betriebs der Bohreinheit 3 zum Abteufen des Hauptschachtes 1 insbesondere durch den Bohrkopf 14 erzeugten Kräfte von der Bohreinheit 3 aufgenommen werden.Furthermore, the illustration according to Fig. 1 It can be seen that the drilling unit 3 is equipped with a number of Verspannmodulen 15 which engage a drilling platform 16 of the drilling unit 3 and are equipped with Verspannzylindern 17 extending in the radial direction, radially inside connected to the drilling platform 16 and radially outside with clamping plates 18 are provided. The Verspannmodule 15 are adapted to the drilling unit 3 to brace radially and axially such that substantially all forces generated during operation of the drilling unit 3 for sinking the main shaft 1 in particular by the drill head 14 are absorbed by the drilling unit 3.

Vorteilhafterweise verfügt die Bohreinheit 3 über einen Außendichtkragen 19, der an den Querschnitt des Hauptschachtes 1 in radialer Richtung, gegebenenfalls unter Beibehalten eines aus Sicherheitsgründen unbedenklichen minimalen Restspaltes, anpassbar ist und die Bohreinheit 3 im Bereich der Bohrplattform 16 gegen die Trägereinheit 2 radial abschließt.Advantageously, the drilling unit 3 has an outer sealing collar 19, which is adaptable to the cross section of the main shaft 1 in the radial direction, optionally while maintaining a minimum residual gap, which is harmless for safety reasons, and radially closes the drilling unit 3 in the area of the drilling platform 16 against the carrier unit 2.

Der Bohrkopf 14 ist mit einer Anzahl von Antriebsmotoren 20 ausgestattet, mit denen ein Drehantrieb 21, der durch einen Stützzylinder 22 stabilisiert ist, zum Drehen um eine in parallel zur Abteufrichtung verlaufende Drehachse antreibbar ist. Der Drehantrieb 21 ist gegenüber der Bohrplattform 16 mit einem Bohrkopfantriebslager 23 gelagert und weist eine Anzahl von Antriebsarmen 24 auf, die sich zwischen dem Drehantrieb 21 und einem Abbaukegelrad 25 erstrecken. Das Abbaukegelrad 25 verfügt in seinem von dem Drehantrieb 23 am weitesten beabstandeten Bereich über eine Abführöffnung 25'.The drill head 14 is equipped with a number of drive motors 20 with which a rotary drive 21, which is stabilized by a support cylinder 22, for rotation about an axis extending in parallel to the Abteufrichtung axis of rotation can be driven. The rotary drive 21 is mounted with respect to the drilling platform 16 with a drill head drive bearing 23 and has a number of drive arms 24 which extend between the rotary drive 21 and a mining bevel gear 25. The mining bevel gear 25 has a discharge opening 25 'in its area furthest from the rotary drive 23.

Das Abbaukegelrad 25 ist mit einer Anzahl von Abbauwerkzeugen 26 bestückt und erstreckt sich in Abteufrichtung entlang einer komplementär kegelförmig ausgebildeten Hauptschachtsohle 27 von radial außen von der Bohrplattform 16 wegweisend in der Anordnung gemäß Fig. 1 zu einem gegenüber dem Hauptschacht 1 im Querschnitt wesentlich kleineren, sich in Verlängerung des Hauptschachtes 1 von einem Hauptschachtmund 28 in Abteufrichtung erstreckenden Vorschacht 29. Die Abführöffnung 25' mündet in den Vorschacht 29, so dass von dem Bohrkopf 14 abgebautes Material über den Vorschacht 29 abförderbar ist.The mining bevel gear 25 is equipped with a number of mining tools 26 and extending in the direction of down along a complementary conically shaped main shaft bottom 27 from radially outside of the drilling platform 16 pioneering in the arrangement according to Fig. 1 to a relative to the main shaft 1 in cross-section much smaller, extending in extension of the main shaft 1 from a main shaft mouth 28 in the lowering direction feed chute 29.
