Abstract

The invention relates to a device for vertically securing pipes having various diameters for elevator systems on oil drilling platforms, where a base element (1) is arranged with a pivotable door element (3), wherein the closing movement for forming a cylinder liner (5) can be carried out by a lockable actuating cylinder (6). The cylinder liner is formed by replaceable cylinder segments (7) in order to form a cylinder liner having diameters of different sizes in the base element and door element. To this end, the cylinder segments (7) are replaceably arranged by means of rear-sided guide profiles and associated profiled rails in the base element and door element. The upper sides of the individual cylinder segments are connected to corresponding receiving elements via horizontally slidable holding rings. By accommodating pipes in the cylinder liner and the occurrence of load, a spring-loaded actuating arm can be height-adjusted via a cylinder segment and a locking of the hydraulic actuating cylinder can be adjusted for the closing movement via an associated load sensor.

The invention relates to a device for vertical mounting of pipes of different diameter for Elevatorsysteme for receiving, lifting and settling a pipe string or individual pipe segments on oil rigs, consisting of a basic element to form a cylinder liner with a pivot joint for a connected door element to complete the Socket, wherein the pivot joint has a spaced-apart closure, which has a pivotable locking with a locking pin and the closing movement is adjustable via an associated hydraulic actuating cylinder.
Ausbildungen dieser Art sind in vielfältigen Ausbildungen bekannt, wobei das Öffnen und Schließen über eine hydraulische Steuerung durch Stellzylinder erfolgt. Es besteht hierbei der Mangel, dass die Anordnungen nur für eine Rohrgröße ausgelegt sind und die Umrüstung der Zylinderbuchse nur mit großem Aufwand vor Ort durchführbar ist. Dabei ist der Gesichtspunkt, dass eine Öffnungsbewegung des Türelementes unter Last bei unterschiedlichen Rohrgrößen nicht durchführbar sein soll in der Praxis von großer Bedeutung sein. Aufgabe der Erfindung ist es, eine einfache umrüstbare Anordnung für unterschiedliche Rohrdurchmesser zu schaffen, die eine Anpassung vor Ort ermöglicht und eine Sicherung der Buchse zur Halterung unter Last gewährleistet . Embodiments of this type are known in various configurations, wherein the opening and closing takes place via a hydraulic control by adjusting cylinder. There is the shortcoming that the arrangements are designed only for a pipe size and the conversion of the cylinder liner is feasible on site with great effort. In this case, the viewpoint that an opening movement of the door element under load at different pipe sizes should not be feasible in practice of great importance. The object of the invention is to provide a simple convertible arrangement for different pipe diameters, which allows an adjustment on site and ensures a backup of the socket for mounting under load.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, dass Zylindersegmente zur Bildung der Zylinderbuchse in unterschiedlichen Größendurchmessern im Grundelement und Türelement über rückseitige Führungsprofile und zugeordnete Profilschienen im Grundelement und Türelement austauschbar angeordnet und die Oberseiten der einzelnen Zylindersegmente über horizontal aufschiebbar zugeordnete Halteringe mit korrespondierenden Aufnahmen verbunden sind, wobei durch Aufnahme von Rohren in der Zylinderbuchse und auftretender Belastung ein federbelasteterThe solution of this object is achieved according to the invention in that cylinder segments arranged to form the cylinder liner in different size diameters in the base element and door element on the rear guide profiles and associated rails in the base element and door element and the tops of the individual cylinder segments are connected via horizontally slidably associated retaining rings with corresponding receptacles, wherein by receiving pipes in the cylinder liner and occurring load a spring-loaded
Betätigungsarm über ein Zylindersegment in seiner Höhe verstellbar sowie über einen zugeordneten Lastsensor eine Verriegelung des hydraulischen Stellzylinders für die Schließbewegung einstellbar ist. Actuating arm via a cylinder segment in height adjustable and via an associated load sensor, a lock of the hydraulic actuating cylinder for the closing movement is adjustable.
Hierdurch sind durch die einzelnen Zylindersegmente bei den vorliegenden Verhältnissen mit relativ großen Durchmessern, Umrüstungen entsprechend der verwendeten Rohrgröße durchführbar und eine lastabhängige Arretierung möglich. As a result, can be carried out by the individual cylinder segments in the existing conditions with relatively large diameters, conversions according to the pipe size used and a load-dependent locking.
Zur guten Fixierung der Zylindersegmente ist vorgesehen, dass die Zylindersegmente im unteren Teil zusätzliche Halteelemente zur korrespondierenden Aufnahme im Grundelement und Türelement aufweisen. Eine vorteilhafte Ausbildung besteht darin, dass drei Zylindersegmente im Grundelement und zwei Zylindersegmente der Zylinderbuchse im Türelement angeordnet sind. For good fixation of the cylinder segments, it is provided that the cylinder segments in the lower part have additional retaining elements for corresponding reception in the base element and door element. An advantageous embodiment is that three cylinder segments are arranged in the base element and two cylinder segments of the cylinder liner in the door element.
Zum automatischen Verschluss des Türelementes nach Einsetzen von Rohren ist vorgesehen, dass ein Zylindersegment im Grundelement einen vorstehenden Trigger-Bolzen aufweist, der nach Aufnahme von Rohren den Stellzylinder für die Schließbewegung steuert. For automatic closure of the door element after insertion of pipes is provided that a cylinder segment in the base element has a protruding trigger bolt which controls the actuating cylinder for the closing movement after receiving tubes.
In weiterer Ausgestaltung und zum Schutz eines eingesetzten Trigger-Bolzens ist vorgesehen, dass der Trigger-Bolzen über eine Feder mit einem Hohlkolbenzylinder verbunden ist, der nach Ansteuerung des Stellzylinders den ' Trigger-Bolzen in einer zurückgezogenen Position hält.

Fig. 14 eine Gesamtdarstellung der Vorrichtung in geschlossener Position der Zylinderbuchse Die Vorrichtung besteht im wesentlichen aus einem Grundelement 1 mit einem über einen Scharnierbolzen 2 verschwenkbaren Türelement 3, das im geschlossenen Zustand über ein Verschlußelement 4 am Grundelement 1 zur Bildung einer Zylinderbuchse 5 über einen Stellzylinder 6 einstellbar ist. Fig. 14 is an overall view of the device in the closed position of the cylinder liner The device consists essentially of a base member 1 with a pivotable about a hinge pin 2 door element 3, which is adjustable in the closed state via a closure element 4 on the base member 1 to form a cylinder liner 5 via a control cylinder 6.
Die Zylinderbuchse 5 wird durch einzelne Zylindersegmente 7 gebildet, die austauschbar am Grundelement l und Türelement 3 festgelegt sind. Hierzu sind die Zylindersegmente 7 mit rückseitigen Führungsprofilen 8 verbunden, die in zugeordnete Profilschienen 9 einschiebbar und gehaltert werden. The cylinder liner 5 is formed by individual cylinder segments 7, which are interchangeably fixed to the base element 1 and door element 3. For this purpose, the cylinder segments 7 are connected to the rear guide profiles 8, which are inserted and held in associated rails 9.
Im oberen Bereich sind die Zylindersegmente 7 über horizontal aufschiebbare Halteringe 10 mit einer korrespondierenden Aufnahme 21 für die Zylindersegmente 9 verbunden. In the upper area, the cylinder segments 7 are connected via horizontally slidable retaining rings 10 with a corresponding receptacle 21 for the cylinder segments 9.
In dieser Ausbildung ist ein Zylindersegment 7 mit einem federbelasteten Betätigungsarm 11 verbunden und wirkt bei eingesetztem Rohr und damit auftretender Belastung auf einem Lastsensor 12, der bei Verschluss der Vorrichtung eine Verriegelung des Stellzylinders 6 durchführt . Der Lastsensor 12 ist eine interne Sperre in der hydraulischen Steuerung des Stellzylinders 6, der eine Öffnung der Zylinderbuchse 5 und Freigabe einer Last verbindet. Ein Bediener bekommt somit ein Signal, sobald der Lastsensor 12 betätigt wurde und sich damit der Elevator unter Last befindet. In this embodiment, a cylinder segment 7 is connected to a spring-loaded actuating arm 11 and acts when inserted tube and thus occurring load on a load sensor 12, which performs a locking of the actuating cylinder 6 when the device is closed. The load sensor 12 is an internal lock in the hydraulic control of the actuator cylinder 6, which connects an opening of the cylinder liner 5 and release of a load. An operator thus receives a signal as soon as the load sensor 12 has been actuated and thus the elevator is under load.
Der hydraulische Stellzylinder 6 ermöglicht ein Öffnen bzw. Schließen des Türelementes 3. Das Türelement 3 lässt sich um 90° öffnen, um Rohre aufnehmen zu können. In geschlossener Position liegt das Türelement 3 auf dem Grundelement 1 auf. Sobald das Türelement 3 geschlossen ist, wird automatisch durch eine hydraulische Steuerung mit einem Ventil 23 ein hydraulischer Verschlußzylinder 22 betätigt. Der Verschlußzylinder 22 ist mit einem Verschluss 13 mit einem Verriegelungsbolzen 14 verbunden und veranlasst damit ein Schließen. Das Türelement 3 wird durch diesen Verschluss 13 mit Verriegelungsbolzen 14 in der geschlossenen Position gehalten und mit dem Grundelement 1 verbunden. Eine zusätzliche Verriegelung verhindert ein ungewolltes Öffnen des Verschlusses, sollte es zu einem Ausfall der Hydraulik oder zu einem Leitungsbruch kommen. The hydraulic actuating cylinder 6 allows opening or closing of the door element 3. The door element 3 can be opened by 90 ° in order to accommodate pipes. In the closed position, the door element 3 rests on the base element 1. As soon as the door element 3 is closed, a hydraulic lock cylinder 22 is automatically actuated by a hydraulic control with a valve 23. The shutter cylinder 22 is connected to a shutter 13 with a locking pin 14, thereby causing a closing. The door member 3 is held by this shutter 13 with locking bolt 14 in the closed position and connected to the base member 1. An additional lock prevents unintentional opening of the closure, should it come to a failure of the hydraulic or to a line break.
In dieser Ausbildung sind drei Zylindersegmente 7 im Grundelement 1 und zwei Zylindersegmente 7 am Türelement 3 angeordnet. Hierbei sind die Zylindersegmente 7 an der Unterseite über zusätzliche Halteelemente 15 und korrespondierende Aufnahmen 16 formschlüssig zur zusätzlichen Führung und Sicherung verbunden. Durch die Ausbildung einzelner Zylindersegmente 7 zur Bildung der Zylinderbuchse 5 erfolgt eine Reduzierung des Gewichts und es verringern sich die Zeiten bei einem Wechsel auf einen anderen Rohrdurchmesser. In this embodiment, three cylinder segments 7 in the base element 1 and two cylinder segments 7 are arranged on the door element 3. Here, the cylinder segments 7 are connected at the bottom via additional holding elements 15 and corresponding receptacles 16 positively for additional guidance and assurance. The formation of individual cylinder segments 7 to form the cylinder liner 5, a reduction in weight and it reduces the times when changing to a different pipe diameter.
Zum automatischen Schließen des Türelementes 3 nach Aufnahme eines Rohres in die geöffnete Zylinderbuchse 5 ist ein Trigger-Bolzen 17 im mittleren Zylindersegment 7 des Grundelementes 1 angeordnet . Auf der Höhe des Trigger-Bolzens 17 befindet sich ein hydraulischer Hohlkolbenzylinder 18, der durch einen Grundkörper mit dem Trigger-Bolzen 17 verbunden ist. Bei Aufnahme eines Rohres schlägt das Rohr gegen den Trigger-Bolzen 17. Der Trigger-Bolzen 17 trifft auf eine Zylinderstange 19 des Hohlkolbenzylinders 18, drückt diese durch den Hohlkolbenzylinder 18 entgegen einer Feder 24 und betätigt ein Trigger-Ventil 20, das den Hohlkolbenzylinder 18 aktiviert. Der Hohlkolbenzylinder 18 bewegt die Zylinderstange 19 und entfernt damit den Trigger-Bolzen 17 vom eingesetzten Rohr. Durch das Zurückfahren des Hohlkolbenzylinders 18 wird ein Verschleiß am Trigger-Bolzen 17 vermieden, der ansonsten ständig am Rohr anliegen würde. Zusätzlich wird bei der Betätigung des Trigger-Ventils 20 aufgrund der hydraulischen Steuerung ein automatisches Verschliessen und Verriegeln des Türelementes 3 veranlasst . For automatically closing the door element 3 after receiving a tube in the open cylinder liner 5, a trigger pin 17 in the middle cylinder segment 7 of the base element 1 is arranged. At the height of the trigger pin 17 is a hydraulic hollow piston cylinder 18 which is connected by a main body with the trigger pin 17. When receiving a tube, the tube strikes against the trigger pin 17. The trigger pin 17 strikes a cylinder rod 19 of the hollow piston cylinder 18, pushes them through the hollow piston cylinder 18 against a spring 24 and actuates a trigger valve 20 which activates the hollow piston cylinder 18. The hollow piston cylinder 18 moves the cylinder rod 19 and thus removes the trigger pin 17 from the inserted tube. By the retraction of the hollow piston cylinder 18 wear on the trigger pin 17 is avoided, which would otherwise constantly abut the pipe. In addition, an automatic closing and locking of the door element 3 is caused by the actuation of the trigger valve 20 due to the hydraulic control.
