Die Aufgabe wird nach der Erfindung durch ein Bohrgestängemagazin mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausführungsformen des Bohrgestängemagazins sind in den abhängigen Ansprüchen angegeben.The object is achieved according to the invention by a drill pipe magazine with the features of claim 1. Preferred embodiments of the drill pipe magazine are indicated in the dependent claims.
Das erfindungsgemäße Bohrgestängemagazin ist dadurch gekennzeichnet, dass die Seitenwände parallel zueinander angeordnet sind und jeweils mindestens ein Schwenklager mit horizontal gerichteter Schwenkachse aufweisen, dass der mindestens eine Aufnahmeboden schwenkbar gegenüber den Seitenwänden gelagert ist und dass der Grundrahmen faltbar ausgebildet ist, wobei der Grundrahmen aus einer zusammengefalteten Faltposition in eine Betriebsposition auffaltbar ist.The drill pipe magazine according to the invention is characterized in that the side walls are arranged parallel to each other and each have at least one pivot bearing with horizontally directed pivot axis, that the at least one receiving base is pivotally mounted relative to the side walls and that the base frame is formed foldable, wherein the base frame of a folded Folded position can be unfolded into an operating position.
Ein Grundgedanke der Erfindung besteht darin, das Bohrgestängemagazin aus einem kastenartigen Grundrahmen aufzubauen, welcher faltbar gestaltet ist. Hierzu sind der Auflagerbereich, die Seitenwände und der mindestens eine Aufnahmeboden zueinander schwenkbar um Schwenklager gelagert. Insbesondere sind alle Schwenkachsen der Schwenklager im Wesentlichen horizontal gerichtet, so dass der Grundrahmen aus einer zusammengefalteten Faltposition in eine Betriebsposition aufgefaltet und aufgerichtet werden kann. In der Faltposition sind die Wand- und Bodenteil etwa parallel zueinander, so dass ein einfacher Transport möglich ist. Durch die schwenkbare Verbindung der Einzelteile des Grundrahmens können diese ohne großen Montage- und Justieraufwand in die Betriebsposition bewegt werden. Grundsätzlich kann das Auffalten des zusammengefalteten Grundrahmens über eine separate Stelleinrichtung, insbesondere einen Kran, erfolgen. Eine bevorzugte Ausführungsform der Erfindung besteht darin, dass eine Stellzylinderanordnung mit mindestens einem Stellzylinder vorgesehen ist, mit welcher der Grundrahmen auffaltbar ist. Die Stellzylinderanordnung ist dabei ein integraler Bestandteil des Bohrgestängemagazins, so dass an der Bau- oder Bohrstelle kein spezielles Hebezeug vorgesehen werden muss.A basic idea of the invention is to construct the drill pipe magazine from a box-like base frame, which is designed to be foldable. For this purpose, the support area, the side walls and the at least one receiving floor are mounted pivotably relative to one another about pivot bearings. In particular, all pivot axes of the pivot bearings are directed substantially horizontally, so that the base frame can be unfolded and erected from a folded folded position into an operating position. In the folded position, the wall and bottom part are approximately parallel to each other, so that a simple transport is possible. Due to the pivotal connection of the individual parts of the base frame, these can be moved into the operating position without great installation and adjustment effort. In principle, unfolding of the folded base frame can take place via a separate setting device, in particular a crane. A preferred embodiment of the invention is that an actuating cylinder arrangement is provided with at least one actuating cylinder, with which the base frame is unfoldable. The actuating cylinder assembly is an integral part of the drill pipe magazine, so that no special hoist must be provided at the construction or drilling.
Eine bevorzugte Weiterbildung der Erfindung besteht darin, dass die Stellzylinderanordnung mindestens zwei Stellzylinder aufweist, welche parallel zueinander entlang einer Seitenwand angeordnet sind. Hierdurch wird eine besonders stabile und kompakte Anordnung geschaffen. Vorzugsweise sind die Stellzylinder als Hydraulikzylinder ausgebildet. An einer Baustelle ist es lediglich erforderlich, die Hydraulikzylinder mit einer Hydraulikfluidquelle zu verbinden. Bei Bereitstellung des erforderlichen Hydraulikdruckes können die Hydraulikzylinder ohne weitere Hilfsmittel von außen das Bohrgestängemagazin, welches eine Höhe von bis zu 20 m oder mehr erreichen kann, auffalten und aufrichten.A preferred embodiment of the invention is that the actuating cylinder arrangement has at least two actuating cylinders, which are arranged parallel to each other along a side wall. As a result, a particularly stable and compact arrangement is created. Preferably, the actuating cylinders are designed as hydraulic cylinders. At a construction site, it is only necessary to connect the hydraulic cylinders to a hydraulic fluid source. When providing the required hydraulic pressure, the hydraulic cylinders can be unfolded and erected without external aids from the outside of the drill pipe magazine, which can reach a height of up to 20 m or more.
Eine weitere bevorzugte Ausführungsform der Erfindung besteht darin, dass die Seitenwände aus mindestens zwei Wandelementen aufgebaut sind, zwischen denen Schwenklager angeordnet sind. Die beiden äußeren Seitenwände müssen dabei nicht die gleiche Anzahl von Wandelementen aufweisen. Vorzugsweise weist eine Seitenwand drei Wandelemente auf, während die gegenüberliegende Seitenwand lediglich zwei Wandelemente umfasst. Die Wandelemente sind jeweils über ein horizontales Schwenklager miteinander verbunden. Durch entsprechende Anordnung der Anzahl von Wandelementen und Schwenklagern kann so eine gewünschte Dimensionierung des Bohrgestänges in der zusammengefalteten Faltposition erreicht werden. Insbesondere kann das Bohrgestängemagazin in der Faltposition derart dimensioniert sein, dass es mit einem herkömmlichen Transportcontainer oder einem üblichen Tieflader transportiert werden kann.A further preferred embodiment of the invention consists in that the side walls are constructed from at least two wall elements, between which pivot bearings are arranged. The two outer side walls need not have the same number of wall elements. Preferably, one side wall has three wall elements, while the opposite side wall comprises only two wall elements. The wall elements are each connected to each other via a horizontal pivot bearing. By appropriate arrangement of the number of wall elements and pivot bearings so a desired dimensioning of the drill string in the folded folded position can be achieved. In particular, the drill pipe magazine can be dimensioned in the folding position so that it can be transported with a conventional transport container or a conventional low loader.
Eine besonders kompakte Anordnung wird nach der Erfindung in bevorzugter Weise dadurch erreicht, dass die Seitenwände jeweils über ein Schwenklager gelenkig an dem Auflagerbereich angebracht sind. Der Auflagerbereich kann dabei wie die anderen Wandelemente gerüstartig oder zur Aufnahme höherer Lagerkräfte massiv ausgebildet sein. Der Auflagerbereich kann auch als Auflagerboden oder Auflagerplatte bezeichnet werden.A particularly compact arrangement is achieved according to the invention in a preferred manner in that the side walls are each mounted via a pivot bearing articulated to the support area. The support area can be made like a solid like the other wall elements or massive to accommodate higher bearing forces be. The support area can also be referred to as a support floor or support plate.
Für ein sicheres und zuverlässiges Auffalten und auch Zusammenfalten des Bohrgestängemagazins ist es nach einer weiteren Ausführungsform der Erfindung vorteilhaft, dass an dem Auflagebereich mindestens eine seitlich vorstehende Stütze angeordnet ist, an der ein Stützarm schwenkbar gelagert ist. Die seitlich vorstehende Stütze und der Schwenkarm sind dabei so dimensioniert, dass diese insbesondere in der Anfangsphase der Auffaltbewegung für eine günstige Kraftverteilung sorgen. Auf diese Weise kann eine wirtschaftliche Dimensionierung der Stellzylinderanordnung erreicht werden.For a secure and reliable unfolding and also folding the drill string magazine, it is advantageous according to a further embodiment of the invention that at least one laterally projecting support is arranged on the support area, on which a support arm is pivotally mounted. The laterally projecting support and the swivel arm are dimensioned such that they provide a favorable force distribution, in particular in the initial phase of the unfolding movement. In this way, an economic dimensioning of the actuating cylinder arrangement can be achieved.
Dabei ist eine besonders gute Kraftverteilung nach einer Ausführungsvariante dadurch möglich, dass der mindestens eine Stellzylinder einerseits an einem ersten Wandelement einer ersten Seitenwand und andererseits an einem Hebelmechanismus mit zwei Kniehebeln angelenkt ist, von denen ein erster Kniehebel mit dem ersten Wandelement und ein zweiter Kniehebel mit einem zweiten Wandelement der ersten Seitenwand gelenkig verbunden ist, welches an das erste Wandelement der ersten Seitenwand angrenzt. Bei Anordnung eines zweiten oder mehrerer Stellzylinder sind entsprechend weitere Kniehebelmechanismen vorzusehen. Insbesondere zu Beginn der Auffaltbewegung kann über den Kniehebelmechanismus, an dessen Knie der Stellzylinder angelenkt ist, eine gute, quer gerichtete Kraftverteilung auf die etwa horizontal liegenden Wandelemente bewirkt werden. Das erste und zweite Wandelement können allein über den Kniehebelmechanismus oder auch über ein Schwenklager verbunden sein.In this case, a particularly good force distribution according to a variant embodiment is possible in that the at least one actuating cylinder is articulated on the one hand to a first wall element of a first side wall and on the other hand to a lever mechanism with two toggle levers, of which a first toggle lever with the first wall element and a second toggle lever a second wall element of the first side wall is hingedly connected, which adjoins the first wall element of the first side wall. In the arrangement of a second or more actuating cylinder according to other knee lever mechanisms are provided. In particular, at the beginning of Auffaltbewegung can on the knee lever mechanism, at the knee of the actuating cylinder is articulated, a good, transverse force distribution on the approximately horizontal wall elements are effected. The first and second wall element may be connected solely via the toggle mechanism or via a pivot bearing.
Eine weitere Verbesserung der Krafteinleitung wird nach einer weiteren Ausführungsvariante dadurch erreicht, dass der Stützarm direkt oder über einen Anlenkhebel mit dem zweiten Wandelement gelenkig verbunden ist. Der Stützarm kann so zu einer verbesserten Kraftverteilung beitragen und weiterhin eine zusätzliche Führung bei der Auffaltbewegung darstellen. Hierdurch kann einer Gefahr eines Verklemmens oder eines Knickens der gerüstartigen Wandelemente entgegengewirkt werden.A further improvement of the introduction of force is achieved according to a further embodiment, characterized in that the support arm is articulated directly or via an articulation lever with the second wall element. The support arm can thus contribute to an improved force distribution and continue to represent an additional guide in the Auffaltbewegung. As a result, a risk of jamming or buckling of the frame-like wall elements can be counteracted.
Grundsätzlich kann der Grundrahmen lediglich zwei Seitenwände aufweisen. Ein besonders stabiler Aufbau für eine größere Anzahl von Bohrgestängeelementen wird gemäß einer weiteren Ausführungsform der Erfindung dadurch erreicht, dass der Grundrahmen mindestens eine vertikale Zwischenwand aufweist, welche zwischen und parallel zu den Seitenwänden angeordnet ist. Es können insbesondere auch zwei oder mehr Zwischenwände parallel zwischen den äußeren Seitenwänden angeordnet sein. Der Abstand zwischen den einzelnen Wänden ist dabei vorzugsweise gleich ausgebildet. Die mindestens eine Zwischenwand bewirkt eine zusätzliche Versteifung und trägt somit zur erhöhten Stabilität des Grundrahmens bei.In principle, the base frame can have only two side walls. A particularly stable structure for a larger number of drill string elements is according to a further embodiment of the invention achieved in that the base frame has at least one vertical partition, which is arranged between and parallel to the side walls. In particular, two or more intermediate walls may be arranged in parallel between the outer side walls. The distance between the individual walls is preferably the same. The at least one intermediate wall causes an additional stiffening and thus contributes to the increased stability of the base frame.
Gemäß einer weiteren Ausführungsform der Erfindung ist es vorteilhaft, dass die Zwischenwand wie eine zweite Seitenwand mit der gleichen Anzahl von Wandelementen ausgebildet ist und dass eine erste Seitenwand mit dem Stützarm verbunden ist und eine geringere Anzahl von Wandelementen aufweist. Dabei können also die eine oder die mehreren Zwischenwände gleich zu mindestens einer Seitenwand ausgebildet sein. Dies erlaubt eine effiziente Fertigung.According to a further embodiment of the invention, it is advantageous that the intermediate wall is formed like a second side wall with the same number of wall elements and that a first side wall is connected to the support arm and has a smaller number of wall elements. In this case, therefore, the one or more intermediate walls can be formed equal to at least one side wall. This allows efficient production.
Weiterhin wird ein stabiler und zugleich leichter Aufbau gemäß einer Ausführungsvariante der Erfindung dadurch erzielt, dass die Wandelemente fachwerkartig aus Metallträgern aufgebaut sind. Es können insbesondere Stahlträger, etwa T- oder Doppel-T-Träger vorgesehen sein, welche zum Bilden der Wandelemente miteinander verschweißt sind.Furthermore, a stable and lightweight construction according to an embodiment of the invention is achieved in that the wall elements are constructed like a truss of metal supports. It can be provided in particular steel beams, such as T or double T-beam, which are welded together to form the wall elements.
Grundsätzlich kann die Ausbildung des mindestens einen Aufnahmebodens, welcher oberhalb des Auflagerbereiches angeordnet ist, beliebig gestaltet sein, sofern eine Aufnahme und Halterung der Bohrgestängeelemente sichergestellt ist. Eine besonders robuste Ausgestaltung wird nach einer Weiterbildung der Erfindung dadurch erreicht, dass die Aufnahmen für die Bohrgestängeelemente an dem Aufnahmeboden durch rechenartig angeordnete Schienen gebildet sind, welche sich etwa horizontal von einem Querträger weg zu dem offenen Zugangsbereich erstrecken. Vorzugsweise sind zwei oder mehr Aufnahmeböden verteilt über die Höhe des Grundrahmens angeordnet, um so ein sicheres Lagern der Bohrgestängeelemente zu ermöglichen. Die Anordnung mit Schienen erlaubt eine zuverlässige Lagerung der Bohrgestängeelemente in Reihen. Es können mehrere Aufnahmeböden übereinander angeordnet sein, so dass Bohrgestängeelemente unterschiedlicher Länge oder zusammengesetzte Gestängestücke gehaltert und abgestützt werden können.In principle, the design of the at least one receiving floor, which is arranged above the support area, can be designed as desired, provided that a receptacle and mounting of the drill string elements is ensured. A particularly robust embodiment is achieved according to a development of the invention in that the receptacles for the drill string elements are formed on the receiving floor by rake-like arranged rails which extend approximately horizontally from a cross member to the open access area. Preferably, two or more receiving bases are arranged distributed over the height of the base frame, so as to allow a secure storage of the drill string elements. The arrangement with rails allows reliable storage of the drill pipe elements in rows. A plurality of receiving trays can be arranged one above the other so that drill string elements of different lengths or composite linkage pieces can be held and supported.
Nach einer Weiterbildung der Erfindung ist es für einen kompakten Aufbau vorteilhaft, dass die Seitenwände und die mindestens eine vertikale Zwischenwand auf dem Auflagerbereich über jeweils eine Sockelleiste schwenkbar gelagert sind und dass die Sockelleisten jeweils eine unterschiedliche Höhe aufweisen, welche in einer Faltrichtung abnimmt. Auf diese Weise können in der zusammengefalteten Position die horizontal angeordneten Elemente weitgehend parallel zueinander angeordnet werden. Die Höhendifferenz der einzelnen Sockelleisten beträgt dabei etwa die Breite der Wandelemente oder ein Vielfaches davon.According to a development of the invention, it is advantageous for a compact construction that the side walls and the at least one vertical partition wall are pivotally mounted on the support area via a respective skirting and that the baseboards each have a different height, which decreases in a folding direction. In this way, in the folded position, the horizontally arranged elements can be arranged substantially parallel to each other. The height difference of the individual baseboards is approximately the width of the wall elements or a multiple thereof.
