Description

Die Erfindung betrifft eine Vorrichtung zum Anschluss eines rohrförmigen Bohrwerkzeuges an den Kraftdrehkopf eines Bohrgerätes nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for connecting a tubular drilling tool to the power rotary head of a drilling device according to the preamble of patent claim 1.

Beim Bohren von tieferen Bohrlöchern werden diese regelmäßig mit Bohrrohren ausgekleidet, um ein Nachrutschen von Erdreich zu verhindern. Mit fortschreitender Tiefe der Bohrung ist die Verrohrung hierzu auch entsprechend in die Tiefe fortzuführen. Dazu werden einzelne Bohrrohre aneinandergesetzt, und der hierdurch gebildete Bohrrohrstrang wird als solches in das Erdreich hineingedrückt. Zur Erleichterung dieser Bewegung wird der gesamte Bohrstrang mit Hilfe des Kraftdrehkopfes eines Bohrgerätes in Drehung versetzt.When drilling deeper wells, these are regularly lined with drill pipes to prevent soil from slipping. As the depth of the hole progresses, the casing must also be continued to depth. For this purpose, individual drill pipes are put together, and the Bohrrohrstrang thereby formed is pressed as such in the soil. To facilitate this movement, the entire drill string is rotated by means of the power turret of a drill.

Die Verbindungsstelle zwischen dem Kraftdrehkopf des Bohrgerätes und dem jeweils neu anzusetzenden Bohrrohr liegt bis zu 6 m über dem Erdboden. Zum Anschluss des jeweiligen Bohrrohrs an das Anschlussrohr des Kraftdrehkopfes ist es bei einem manuellen Anschluss erforderlich, das jeweils eine Person an einer Leiter nach oben zur Verbindungsstelle steigt, und die erforderlichen Verbindungsbolzen einbringt. Alternativ geschieht dies mittels einer Teleskopstange von der Standebene des Bohrgerätes aus. Da die Bohrrohre typischerweise einen Durchmesser von 600 bis 2000 mm aufweisen, muss die Leiter zum Einbringen der einzelnen Verbindungsbolzen mehrmals angestellt werden. Das Herstellen der mechanischen Verbindung zwischen dem jeweils anzusetzenden Bohrrohr und dem Anschlussrohr des Kraftdrehkopfes ist daher zeitaufwändig und gefährlich. Nach Abschluss einer Bohrung wird der Bohrstrang unter Drehen und Ziehen des Kraftdrehkopfes wieder aus dem Bohrloch herausgezogen. Sobald ein Bohrrohr völlig über dem Erdreich liegt, wird es von dem darunter liegenden Strangteil wieder abgetrennt. Anschließend muss die Verbindung zwischen dem Bohrrohrende und dem Anschlussrohr des Kraftdrehkopfes des Bohrgerätes in analoger Weise wieder in großer Höhe gelöst werden.The connection point between the power drill head of the drilling rig and the drill pipe to be newly attached is up to 6 m above the ground. For connecting the respective drill pipe to the connection tube of the power rotary head, it is necessary with a manual connection, which rises in each case a person at a ladder up to the connection point, and introduces the necessary connecting bolts. Alternatively, this is done by means of a telescopic rod from the level of the drill rig. Since the drill pipes typically have a diameter of 600 to 2000 mm, the ladder for inserting the individual connecting bolts must be made several times. Making the mechanical connection between the respective drill pipe to be attached and the connecting tube of the power rotary head is therefore time-consuming and dangerous. After completing a drilling, the drill string is pulled back out of the hole by turning and pulling the power turret. Once a drill pipe is completely above the soil, it is separated from the underlying strand part again. Subsequently, the connection must between the drill pipe end and the connecting pipe of the power rotary head of the drilling machine can be solved in a similar manner again at high altitude.

Um dieser Problematik entgegenzutreten, wird in der CH 675747 A5 vorgeschlagen, die Herstellung und Aufhebung der mechanischen Verbindung zwischen oberem Bohrrohrende und dem Anschlussrohr des Kraftdrehkopfes über eine ferngesteuert betätigbare Riegelkupplung zwischen dem Anschlussrohr und dem oberen Bohrrohrende automatisch vorzunehmen. Die Riegelkupplung umfasst dabei Kupplungsstifte, die durch eine Servoantriebseinrichtung in fluchtende Löcher am unteren Ende des Anschlussrohres bzw. oberen Bohrrohrende eingeführt werden können. Die Servoantriebseinrichtung ist dabei entweder durch einen Betätigungsring gebildet, der über einen Ritzelantrieb verbunden ist, oder durch hydraulische Arbeitszylinder deren Kolbenstangenenden die Kupplungsstifte bilden.To counter this problem, is in the CH 675747 A5 proposed to automatically make the production and cancellation of the mechanical connection between the upper drill pipe end and the connection tube of the power turret via a remote-controlled lock coupling between the connection pipe and the upper Bohrrohrende. The lock coupling comprises coupling pins which can be inserted by means of a servo drive device into aligned holes at the lower end of the connecting pipe or upper drill pipe end. The servo drive device is formed either by an actuating ring which is connected via a pinion drive, or by hydraulic cylinders whose piston rod ends form the coupling pins.

Nachteilig an dieser vorbekannten Lösung ist, dass diese sehr aufwändig ist. Zudem erweist sich die Zuführung von Pneumatik- oder Hydraulikfluiden über Drehdurchführungen häufig als Fehler- und Leckageanfällig.A disadvantage of this previously known solution that this is very expensive. In addition, the supply of pneumatic or hydraulic fluids via rotary unions often proves to be faulty and leaking.

Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aufgabe zu Grunde, eine Vorrichtung zum Anschluss eines rohrförmigen Bohrwerkzeuges an den Kraftdrehkopf eines Bohrgerätes bereitzustellen, die einfach aufgebaut ist und bei der die vorgenannten Nachteile vermieden sind. Gemäß der Erfindung wird diese Aufgabe durch eine Vorrichtung mit den Merkmalen des kennzeichnenden Teils des Patentanspruchs 1 gelöst.The invention aims to remedy this situation. The invention is based on the object to provide a device for connecting a tubular drilling tool to the power turret of a drill, which is simple in construction and in which the aforementioned disadvantages are avoided. According to the invention, this object is achieved by a device having the features of the characterizing part of patent claim 1.

Mit der Erfindung ist eine Vorrichtung zum Anschluss eines rohrförmigen Bohrwerkzeuges an den Kraftdrehkopf eines Bohrgerätes bereitgestellt, die einfach aufgebaut ist und bei der die vorgenannten Nachteile vermieden sind. Durch die Anordnung von Mitteln zur autarken Energieerzeugung direkt an dem Anschlussrohr ist eine Drehdurchführung für Pneumatik- oder Hydraulikfluide nicht erforderlich.With the invention, a device for connecting a tubular drilling tool to the power turret of a drilling device is provided, which is simple in construction and in which the aforementioned disadvantages are avoided. Due to the arrangement of means for autonomous power generation directly to the connection pipe a rotary feedthrough for pneumatic or hydraulic fluids is not required.

In Weiterbildung der Erfindung ist der Aktuator durch einen Hydraulik- oder Pneumatikzylinder gebildet. Hierdurch ist ein mechanisch besonders einfacher Aufbau ermöglicht.In a further development of the invention, the actuator is formed by a hydraulic or pneumatic cylinder. This allows a mechanically particularly simple construction.

In Ausgestaltung der Erfindung umfassen die Mittel zur autarken Energieerzeugung wenigstens einen Pumpzylinder, der mit einem Druckbehälter verbunden ist, mit dem die wenigstens zwei Aktuatoren verbunden sind. Hierdurch ist ein einfach aufgebauter und zugleich robuster Energiespeicher bereitgestellt.In an embodiment of the invention, the means for autonomous power generation comprise at least one pump cylinder which is connected to a pressure vessel, with which the at least two actuators are connected. As a result, a simply constructed and at the same time robust energy storage is provided.

In weiterer Ausgestaltung der Erfindung ist der Pumpzylinder über Betätigungsmittel betrieben, die durch den Einschub eines aufzunehmenden Bohrwerkzeuges in das Anschlussrohr antreibbar sind. Hierdurch ist eine Zuführung und Speicherung der mit den Einschub des Bohrwerkzeuges bereitgestellten kinetischen Energie erzielt.In a further embodiment of the invention, the pump cylinder is operated via actuating means which can be driven by the insertion of a male boring tool into the connecting pipe. As a result, a supply and storage of the provided with the insertion of the drilling tool kinetic energy is achieved.

In Weiterbildung der Erfindung umfassen die Betätigungsmittel eine Schubstange, die durch ein aufzunehmendes Bohrwerkzeug betätigbar ist. Hierdurch ist eine einfache mechanische Zuführung der kinetischen Energie an den Pumpzylinder ermöglicht.In a further development of the invention, the actuating means comprise a push rod which can be actuated by a male drilling tool. This allows a simple mechanical supply of kinetic energy to the pump cylinder.

In einer alternativen Ausgestaltung der Erfindung sind die Betätigungsmittel durch das Anschlussrohr selbst gebildet, dass in einem Aufnahmekopf vertikal verschiebbar gelagert ist. Durch das Einbringen des Bohrwerkzeuges ist so eine vertikale Lageänderung des Anschlussrohrrohres erzielt, wodurch wiederum eine Weiterleitung der kinetischen Energie zu dem Pumpzylinder ermöglicht ist.In an alternative embodiment of the invention, the actuating means are formed by the connecting pipe itself, that is mounted vertically displaceable in a receiving head. By introducing the drilling tool so a vertical change in position of the connecting pipe tube is achieved, which in turn allows a transmission of the kinetic energy to the pump cylinder.

In Weiterbildung der Erfindung ist der Verriegelungsbolzen über eine Schwinge mit dem Aktuator verbunden, wobei die Schwinge über ein Federelement in Schließposition des Verriegelungsbolzens vorgespannt ist. Hierdurch ist eine einfache mechanische Umlenkung der von dem Aktuator zugeführten kinetischen Energie in die Verschieberichtung des Verriegelungsbolzens erzielt. Durch die Vorspannung des Verriegelungsbolzens über ein Federelement in Schließposition ist eine Energiezufuhr nur zur Entriegelung der Verriegelungsbolzen erforderlich, wodurch der Energiebedarf reduziert ist. Zugleich ist so ein unbeabsichtigtes Herausgleiten der Verriegelungsbolzen aufgrund eines Ausfalls der Mittel zur autarken Energieerzeugung verhindert.In a further development of the invention, the locking bolt is connected via a rocker to the actuator, wherein the rocker is biased by a spring element in the closed position of the locking bolt. As a result, a simple mechanical deflection of the kinetic energy supplied by the actuator is achieved in the direction of displacement of the locking bolt. Due to the bias of the locking bolt via a spring element in the closed position is a power supply only for unlocking the locking bolt required, whereby the energy requirement is reduced. At the same time an inadvertent sliding out of the locking bolt due to failure of the means for self-sufficient energy generation is prevented.

In Ausgestaltung der Erfindung ist das Federelement in den Aktuator integriert. Hierdurch ist eine kompakte Bauweise erzielt.In an embodiment of the invention, the spring element is integrated in the actuator. As a result, a compact design is achieved.

In weiterer Ausgestaltung der Erfindung ist der Aktuator mit einer Funksteuerung verbunden, über welche dieser fernbedienbar ist. Hierdurch ist eine Verund Entriegelung der Verbindung zwischen Bohrwerkzeug und Anschlussrohr außerhalb des unmittelbaren Arbeitsbereichs ermöglicht.In a further embodiment of the invention, the actuator is connected to a radio control, via which it is remotely controllable. As a result, a Verund unlocking the connection between the drilling tool and connecting pipe outside of the immediate work area allows.

In Weiterbildung der Erfindung sind die wenigstens zwei Verriegelungsbolzen an ihrem der Schwinge abgewandten Ende konisch ausgebildet. Hierdurch ist die Einführung des jeweiligen Verriegelungsbolzens in die jeweilige Öffnung des Bohrwerkzeuges erleichtert.In a further development of the invention, the at least two locking bolts are conically formed at their end facing away from the rocker. As a result, the introduction of the respective locking bolt is facilitated in the respective opening of the drilling tool.

In weiterer Ausgestaltung der Erfindung weist der Verriegelungsbolzen an seinem der Schwinge abgewandten Ende eine winklig angestellte Steuerfläche auf. Hierdurch ist ein Herausschieben des Verriegelungsbolzens durch den Einschub eines Bohrwerkzeuges in das Anschlussrohr erzielt. Die Steuerfläche ermöglicht ein gleichmäßiges Abgleiten des Verriegelungsbolzens entlang des eingeschoben Bohrwerkzeuges, wodurch ein Verkanten des Bohrwerkzeuges an dem Verriegelungsbolzen vermieden ist. Vorzugsweise ist die Steuerfläche in einem Winkel von 20° bis 40°, bevorzugt in einem Winkel von 30° zur Stirnfläche des Verriegelungsbolzens angestellt.In a further embodiment of the invention, the locking bolt at its end facing away from the rocker an angled employed control surface. As a result, a pushing out of the locking bolt is achieved by the insertion of a drilling tool in the connecting pipe. The control surface allows a smooth sliding of the locking bolt along the inserted drilling tool, whereby tilting of the drilling tool is avoided on the locking bolt. Preferably, the control surface is set at an angle of 20 ° to 40 °, preferably at an angle of 30 ° to the end face of the locking bolt.

Der Kolbenspeicher 4 ist wiederum über eine - nicht dargestellte - Leitung über einen Hydrauliktank 44 mit einem Pumpzylinder 41 verbunden, an dessen Kolben 411 eine Druckstange 42 befestigt ist. Der Hydrauliktank 44 dient der Speisung des Kolbenspeicherrohrs mit Hydrauliköl. Die Druckstange 42 ist an ihrem dem Pumpzylinder 41 gegenüberliegenden Ende mit einer Schubklaue 43 versehen, die durch eine Öffnung 17 des Anschlussrohres 1 in dieses hineinragt. Zwischen dem Kolbenspeicher 4 und den Hydraulikzylindern 31 der Verriegelungseinrichtungen 3 ist ein Schaltventil 5 angeordnet, das über eine Funksteuerung 51 ansteuerbar ist.The piston 31 is connected via a - not shown - hydraulic line with a piston accumulator 4. In the exemplary embodiment, the gas side of the piston accumulator 4 is filled with nitrogen. The piston accumulator 4 is in turn connected via a - not shown - line via a hydraulic tank 44 with a pump cylinder 41, on the piston 411 a push rod 42 is attached. The hydraulic tank 44 serves to supply the piston accumulator tube with hydraulic oil. The push rod 42 is provided at its end opposite the pump cylinder 41 with a push claw 43 which projects through an opening 17 of the connection pipe 1 in this. Between the piston accumulator 4 and the hydraulic cylinders 31 of the locking devices 3, a switching valve 5 is arranged, which can be controlled via a radio control 51.

Die Verriegelungseinrichtung 3 ist in Figur 5 detailliert dargestellt. Wie dort ersichtlich ist der Kolben 311 des Hydraulikzylinders 31 mit der Schwinge 32 verbunden, die über ein Schwingenlager 36 schwenkbar gelagert ist und an ihrem dem Kolben 311 entgegengesetzten Ende mit dem Verriegelungsbolzen 33 verbunden ist. Der Verriegelungsbolzen 33 ist in der Durchführung 12 des Anschlussrohrs 1 verschiebbar geführt, die hierzu in Art einer nach außen auskragenden Muffe ausgebildet ist.The locking device 3 is in FIG. 5 shown in detail. As can be seen there, the piston 311 of the hydraulic cylinder 31 is connected to the rocker 32, which is pivotally mounted via a rocker bearing 36 and is connected at its end opposite the piston 311 with the locking bolt 33. The locking bolt 33 is slidably guided in the passage 12 of the connecting pipe 1, which is designed for this purpose in the manner of an outwardly projecting sleeve.

Der Verriegelungsbolzen 33 ist in Figur 7 detailliert dargestellt. Der Verriegelungsbolzen 33 ist im Wesentlichen zylindrisch ausgebildet und weist an seinem der Schwinge 32 zugewandten Ende ein im Wesentlichen quaderförmiges Anschlussstück 35 auf, das zur Verbindung mit der Schwinge 32 mit einer Durchführung 351 versehen ist. An seinem der Schwinge 32 gegenüberliegenden Ende ist der Verriegelungsbolzen 33 konisch zulaufend ausgebildet und mit einer Steuerfläche 34 versehen, die winklig zur Stirnfläche des Verriegelungsbolzens 33 angestellt ist. Im Ausführungsbeispiel weist die Steuerfläche 34 zur Stirnfläche des Verriegelungsbolzens 33 einen Winkel von 30° auf.The locking bolt 33 is in FIG. 7 shown in detail. The locking bolt 33 is formed substantially cylindrical and has at its end facing the rocker 32 a substantially parallelepiped connection piece 35 which is provided for connection to the rocker 32 with a passage 351. At its opposite end of the rocker 32, the locking bolt 33 is tapered and provided with a control surface 34 which is employed at an angle to the end face of the locking bolt 33. In the exemplary embodiment, the control surface 34 to the end face of the locking bolt 33 at an angle of 30 °.

Die beiden an dem Anschlussrohr 1 angeordneten Verriegelungseinrichtungen 3 sind nach außen durch eine Abdeckhaube 7 geschützt, welche beabstandet zu dem Anschlussrohr 1 mit diesem schwenkbar verbunden ist.The two arranged on the connecting pipe 1 locking devices 3 are protected to the outside by a cover 7, which is spaced from the connecting pipe 1 with this pivotally connected.

Zur Verbindung eines Bohrrohres 6 mit dem an dem Kraftdrehkopf 2 angeordneten Anschlussrohr 1 wird das Bohrrohr 6 in das Anschlussrohr 1 eingeschoben, bis der endseitige durchmesserreduzierte Abschnitt 63 des Bohrrohrs 6 vollständig von dem Anschlussrohr 1 aufgenommen ist, so dass dieses an dem durch den durchmesserreduzierten Abschnitt 63 gebildeten Absatz 61 des Bohrrohres 6 anliegt. Beim Einbringen des Bohrrohres 6 in das Anschlussrohr 1 wird der durchmesserreduzierte endseitige Abschnitt 63 des Bohrrohres 6 entlang der Steuerfläche 34 der Verriegelungsbolzen 33 geführt, so dass diese durch die Durchführungen 12 des Anschlussrohrs 1 entgegen Ihrer Vorspannung nach außen gedrückt werden. Gleichzeitig wird der durchmesserreduzierte Endabschnitt 63 des Bohrrohres 6 von der durch die Öffnung 17 in das Anschlussrohr 1 hineinragenden Schubklaue 43 der Druckstange 42 aufgenommen, die von dem Bohrrohr 6 in Richtung der Lasche 11 des Anschlussrohres 1 nach oben bewegt wird. Hierdurch wird der Kolben 411 des mit dem Kolbenspeicher 4 verbundenen Pumpzylinders 41 bewegt, wodurch Hydrauliköl aus dem Hydrauliktank 44 in den Kolbenspeicher 4 gepumpt wird, wodurch dort ein Überdruck gebildet wird. In der Endposition des Bohrrohres 6, in der der Absatz 61 an dem Anschlussrohr 1 anliegt, gleiten die konusförmigen Enden der unter Vorspannung stehenden Verriegelungsbolzen 33 entlang der Durchführung 12 des Anschlussrohres 1 durch das Anschlussrohr 1 in mit den Durchführungen 12 fluchtende Verbindungsbohrungen 62 des Bohrrohres 61 hinein, wodurch das Bohrrohr 6 mit dem Anschlussrohr 1 formschlüssig verbunden ist.To connect a drill pipe 6 with the arranged on the power rotary head 2 connection pipe 1, the drill pipe 6 is inserted into the connection pipe 1 until the end-side reduced diameter portion 63 of the drill pipe 6 is completely absorbed by the connection pipe 1, so that this at the through the reduced diameter portion 63 formed paragraph 61 of the drill pipe 6 is applied. When introducing the drill pipe 6 into the connection pipe 1, the diameter-reduced end-side section 63 of the drill pipe 6 is guided along the control surface 34 of the locking bolt 33, so that they are pressed outwards through the passages 12 of the connection pipe 1 against their bias. At the same time the reduced diameter end portion 63 of the drill pipe 6 is received by the projecting into the connecting pipe 1 through the opening 17 thrust pawl 43 of the push rod 42 which is moved by the drill pipe 6 in the direction of the tab 11 of the connection pipe 1 upwards. As a result, the piston 411 of the piston accumulator 4 connected to the pumping cylinder 41 is moved, whereby hydraulic oil is pumped from the hydraulic tank 44 in the piston accumulator 4, whereby there is an overpressure is formed. In the end position of the drill pipe 6, in which the shoulder 61 bears against the connection pipe 1, the conical ends of the prestressed locking bolts 33 slide along the passage 12 of the connecting pipe 1 through the connecting pipe 1 in with the bushings 12 aligned connecting holes 62 of the drill pipe 61 into it, whereby the drill pipe 6 is positively connected to the connecting pipe 1.

Zum Lösen der Verbindung zwischen dem Bohrrohr 6 und dem Anschlussrohr 1 kann das mit der Funksteuerung 51 verbundene Schaltventil 5 aus der Ferne betätigt werden. Durch den zuvor in dem Kolbenspeicher 4 aufgebauten Hydrauliköl-Überdruck werden nun die Hydraulikzylinder 31 der Verriegelungseinrichtungen 3 betätigt, wodurch die Verriegelungsbolzen 33 entgegen ihrer Vorspannung aus den Verbindungsbohrungen 62 des Bohrrohres 6 hinausbewegt werden. Wird kein Signal mehr an die Funksteuerung 51 gesendet, schaltet das Schaltventil 5 in die Ausgangsstellung, und die in dem Hydraulikzylindern 31 befindlichen Hydraulikölmengen fließen in den Hydrauliktank 44 ab. Aufgrund der durch die in den Hydraulikzylindern 31 integrierten Federpakete auf die Verriegelungsbolzen 33 einwirkende Vorspannkraft werden diese wieder durch die Durchführungen 12 des Anschlussrohres 1 in die Position "verriegelt" zurückbewegt.To release the connection between the drill pipe 6 and the connection pipe 1, the switching valve 5 connected to the radio control 51 can be actuated remotely. By the hydraulic oil overpressure previously established in the piston accumulator 4, the hydraulic cylinders 31 of the locking devices 3 are now actuated, whereby the locking bolts 33 are moved out of the connecting bores 62 of the drill pipe 6 against their bias. If no signal is sent to the radio control 51, the switching valve 5 switches to the starting position, and the amounts of hydraulic oil in the hydraulic cylinders 31 flow into the hydraulic tank 44. Due to the prestressing force acting on the locking bolts 33 by the spring assemblies integrated in the hydraulic cylinders 31, they are again moved back through the passages 12 of the connecting pipe 1 into the position "locked".

Im Ausführungsbeispiel gemäß Figur 4 ist die mit der Lasche 11 versehene Stirnplatte 13 des Anschlussrohres 1 über einen an dieser angeordneten, das Anschlussrohr 1 umfassenden Kragen 14 mit dem Anschlussrohr 1 verbunden. In dem Kragen 14 sind diametral gegenüberliegend zwei Langlöcher 15 eingebracht, in die jeweils eine an dem Anschlussrohr 1 angeordnete Achse 16 eingreift, so dass die mit dem Kragen 14 versehene Stirnplatte 13 relativ zu dem Anschlussrohr 1 verschiebbar ist. In diesem Ausführungsbeispiel ist an dem Anschlussrohr 1 keine Druckstange angeordnet. Die Pumpzylinder 41 sind hier unterhalb des umlaufenden Kragens 14 an dem Anschlussrohr 1 angeordnet, wobei die Kolben 411 der Pumpzylinder 41 mit dem Kragen 14 verbunden sind. Die Befüllung des Kolbenspeichers 4 mit Hydrauliköl wird in diesem Ausführungsbeispiel durch eine Relativbewegung zwischen dem Anschlussrohr 1 und der Stirnplatte 13 erzielt, wodurch die Kolben 411 innerhalb der Pumpzylinder 41 bewegt werden, welche Pumpzylinder 41 wiederum über den Hydrauliktank 44 mit dem Kolbenspeicher 4 verbunden sind. Die Relativbewegung zwischen dem Anschlussrohr 1 und der Stirnplatte 13 erfolgt im Zuge der Aufnahme des Bohrrohres 16, wobei das Anschlussrohr 1 auf das Bohrrohr 6 aufgestülpt wird, wodurch die Stirnplatte 13 mit den an dieser über den Kragen 14 befestigten Kolben 411 der Pumpzylinder 41 auf das Anschlussrohr 1 gepresst wird, wodurch die Pumpzylinder 41 betätigt werden.In the embodiment according to FIG. 4 is provided with the tab 11 end plate 13 of the connecting pipe 1 via a arranged on this, the connecting pipe 1 comprehensive collar 14 connected to the connecting pipe 1. In the collar 14, two elongated holes 15 are diametrically opposed introduced, in each of which an arranged on the connecting pipe 1 axis 16 engages, so that provided with the collar 14 end plate 13 is displaceable relative to the connecting pipe 1. In this embodiment, no pressure rod is arranged on the connecting pipe 1. The pump cylinders 41 are arranged here below the circumferential collar 14 on the connection pipe 1, wherein the pistons 411 of the pump cylinder 41 are connected to the collar 14. The filling of the piston accumulator 4 with hydraulic oil is achieved in this embodiment by a relative movement between the connecting pipe 1 and the end plate 13, whereby the pistons 411 are moved within the pumping cylinder 41, which pump cylinders 41 are in turn connected via the hydraulic tank 44 to the piston accumulator 4. The relative movement between the connection pipe 1 and the end plate 13 takes place in the course of receiving the drill pipe 16, wherein the connection pipe 1 is slipped on the drill pipe 6, whereby the end plate 13 is pressed with the piston 411 of the pump cylinder 41 attached to this via the collar 14 on the connection pipe 1 is, whereby the pumping cylinder 41 are actuated.

Die erfindungsgemäße Vorrichtung zeichnet sich insbesondere dadurch aus, dass die Verriegelungsbolzen in Ruheposition über Federpakete in Verschließposition vorgespannt sind und dass das zur Entriegelung der Verriegelungsbolzen erforderliche Hydrauliksystem absolut autark ist und keine äußere Energiezufuhr benötigt. Die erforderliche Energie wird im System durch die Pumpzylinder gewonnen, welche ausschließlich über die Einschubbewegung des Bohrrohres in das Anschlussrohr betätigt werden.The inventive device is characterized in particular by the fact that the locking bolts are biased in the rest position via spring assemblies in the closing position and that the required to unlock the locking bolt hydraulic system is completely self-sufficient and no external power supply needed. The required energy is gained in the system by the pump cylinder, which are actuated exclusively by the insertion movement of the drill pipe in the connecting pipe.
