Description
Diese Bohrvorrichtung weist jedoch noch eine Vielzahl von Komponenten auf, die zwar modular angeordnet sind, aber auf- und abgebaut und von Bohrlokalität zu Bohrlokalität transportiert werden müssen. Dazu ist ein erheblicher Personal- und Logistikaufwand notwendig.
Vorzugsweise ist die Trageinrichtung in einer Art Schwinge, z. B. in Form einer Kastenkonstruktion, ausgebildet.
In diesem Beispiel wird der Kraftdrehkopf 2 außen an der Schwinge mittels eines Aufnahmeblechs 25 geführt, an der das Kraftdrehkopfgehäuse 26 mit dem Kraftdrehkopf 2 befestigt ist. 27 zeigt die Antriebswelle des Kraftdrehkopfes.
Als Alternative (nicht dargestellt) kann die Führung des Kraftdrehkopfes auch innerhalb der Trageinrichtung angeordnet sein.
Die Figuren 4, 5, und 6 zeigen ein Ausführungsbeispiel für eine Gestängehandling-Einheit. Die Gestängehandlingvorrichtung 30 besteht aus einer Schere 34, um den Hub aus der Trageinrichtung 1 heraus zu ermöglichen, aus einer Linearführung 39 auf dem Oberschlitten 45 und aus zwei Greifereinheiten, bestehend jeweils aus der Greiferaufnahme 36, dem Greifer 37 selbst, einem Greiferarm 38, einem Spreizkegel 41, einer Aufnahmeplatte 46 sowie Rollen für den Greifarm 48.
Die Aufnahme 79 für die Gestänge können mittels dieses Verschiebesystems in zwei Richtungen verschoben oder untereinander ausgetauscht werden.
Das System ist mit Schienen 95, 96 sowohl in Längs- als auch in Querrichtung ausgestaltet. Die Aufnahmen verfügen über Spurkranzrollen an ihrer Unterseite, über welche die linearen Bewegungen sicher durchgeführt werden können.
Das Umsetzen von der Längs-auf die Querbahn kann insbesondere über Drehtische 97 oder Drehscheibe oder über Hubeinrichtungen (nicht dargestellt) erfolgen.
Bei der Drehtisch-Ausführung steht die Aufnahme auf einem Schienensystem, welches auf einer Drehvorrichtung installiert ist. Um von der Längs- in die Querrichtung zu gelangen, wird die Aufnahme mittels Drehtisch gedreht. Die Aufnahme kann nun in eine hintere Position rollen. Um wieder in Längsrichtung zu gelangen, wird erneut mittels Drehtisch gedreht.
Eine weitere Ausführungsform ist eine Hubeinrichtung unter den Querförderschienen 96. Die Aufnahme wird längs verschoben. In der Wechselposition von längs auf quer wird die Querschiene angehoben. Die Längsrollen heben von der Schiene 95 ab und die Querrollen setzen auf die Querschiene 96 auf. Nun kann die Aufnahme auf die hintere Bahn aus zwei Längsschienen 95 gerollt werden.
Die Aufnahme 79 verfügt über nicht dargestellte Längs-und Querrellen, die höhenversetzt sind, um im Schienensystem voneinander unabhängig sein zu können.
Die Stahlbaustruktur besteht aus Eckstielen 90, wobei hier nur die hinteren beiden dargestellt sind sowie einer Verbindungs- bzw. Abdeckplatte 98, die die Eckstiele 90 miteinander verbindet und der Stahlbaustruktur Stabilität verleiht. Darüber hinaus ist an ihr die Verriegelungsvorrichtung 60 befestigt, mit der eine Bohrvorrichtung am Einführungsdeckel der Trageinrichtung 70 arretiert werden kann. Die notwendigen Spülungsschläuche sind nicht dargestellt. Die Verbindungsplatte 98 kann auch aus fest miteinander verbundenen Stahlträgern bestehen. Auch die Eckstiele 90 können aus miteinander verbundenen Stahlprofilen aufgebaut sein. Auch kann die Stahlbaustruktur aus zwei, drei oder mehreren Eckstielen 90 aufgebaut sein.
Im Normalfall werden jedoch Gestängehändlingsvorrichtungen 30 verwendet, die Hubbewegungen ausführen können.
Die Trageinrichtungen 1 sind auch über Drehkränze 6 drehbar gelagert, um z. B. zur Entnahme eines Gestänges 78 aus dem Gestängelager 79 eine 90 -Drehung auszuführen. Die Schwenkvorrichtung 5 und die Hubvorrichtung 7 sind in diesem Falle entbehrlich. Sie ist aber dann einsetzbar, wenn an einer anderen Bohrlokalität, z. B. mit nur einer Bohrvorrichtung, schräg gebohrt werden oder die Trageinrichtung 1 erstmals aufgerichtet werden soll.
