Description

Antriebsvorrichtung für eine Bohrstange Drive device for a boring bar
Die Erfindung betrifft eine Antriebsvorrichtung für eine Bohrstange, insbesondere für Decokinganlagen.The invention relates to a drive device for a boring bar, in particular for decoking systems.
In Ölraffinerien wird die letzte, anderweitig nicht mehr nutzbare Fraktion des Rohöls in Koks umgewandelt. Diese Umwandlung findet durch Einleiten dieser Fraktion in Trommeln statt, die sich mit wachsender Betriebsdauer mit Koks füllen. Ist der maximale Füllstand der Trommeln erreicht, wird der Koks aus den Trommeln herausgeschnitten.In oil refineries, the last, otherwise unusable fraction of the crude oil is converted into coke. This conversion takes place by introducing this fraction into drums which fill with coke as the operating time increases. When the maximum level of the drums is reached, the coke is cut out of the drums.
Dieses sogenannte "Decoking" wird üblicherweise mit Hochdruck-Wasserstrahlen durchgeführt, die den Koks zerkleinern und aus den Trommeln herausspülen. Das Werkzeug zum Erzeugen dieser Hochdruck- Wasserstrahlen wird über ein Bohrgestänge von oben in die Trommel eingeführt. Gegenstand der vorliegenden Erfindung ist insbesondere die Ausbildung des Bohrstangen-Antriebs und damit auch des Übergangs von der Wasserversorgung zur Bohrstange.This so-called "decoking" is usually carried out with high-pressure water jets, which shred the coke and flush it out of the drums. The tool for generating these high-pressure water jets is inserted into the drum from above via a drill pipe. The present invention particularly relates to the design of the boring bar drive and thus also the transition from the water supply to the boring bar.
Dieser Übergang von der Wasserversorgung zur Bohrstange ist bei bekannten, gattungsbildenden Anlagen als einteilige Zuführung ausgebildet. Das erste, obere Ende ist mit einem Flansch der Wasserversorgung verbunden. Das zweite, untere Ende der Zu- führung ist mit dem Flansch der Bohrstange verbunden. Dieses zweite, untere Ende ist üblicherweise in einem Axial- und einem Radiallager gelagert, um eine störungsfreie Rotation zu ermöglichen. Weiter setzt am zweiten Ende der Zuführung ein Getriebe an, das im Betriebszustand die Zuführung und die Bohrstange in Rotation versetzt. Wasserversorgung, Zuführung und Bohrstange sind miteinander derart fluchtend und flüs- sigkeitsdicht verbunden, daß ein am freien Ende der Bohrstange angebrachtes Werkzeug zum Abbauen von Koks im Betriebszustand mit dem erforderlichen Wasser versorgt wird. Im Bereich der Zuführung sind vor allem die Packungsringe, die am Übergang von stehenden und rotierenden Bauteilen angeordnet sind, Verschleißteile, die in regelmäßigen Abständen ausgetauscht werden können. Tritt Verschleiß auf, zeigt sich dieser am ersten Ende der Zuführung, dort wo eine flüssigkeitsdichte Verbindung zur Wasserversorgung herzustellen ist und gleichzeitig stehende und rotierende Teile der Antriebsvorrichtung aneinander angrenzen. Die Packungsringe, die diesen Übergang von feststehenden und rotierenden Bauteilen als Dichtungselemente abdichten, müssen bei bekannten Anlagen wartungsunfreundlich bei eingebauten Bohrstangenantrieb im Stahlgerüst der Decokinganlage ausgetauscht werden.This transition from the water supply to the boring bar is designed as a one-piece feed in known, generic systems. The first, upper end is connected to a flange of the water supply. The second, lower end of the feed is connected to the flange of the boring bar. This second, lower end is usually mounted in an axial and a radial bearing in order to enable trouble-free rotation. At the second end of the feeder there is a gearbox which, when in operation, sets the feeder and the boring bar in rotation. The water supply, feed and boring bar are connected to one another in such a flush and liquid-tight manner that a tool attached to the free end of the boring bar for removing coke is supplied with the required water in the operating state. In the area of the infeed, the packing rings, which are arranged at the transition from standing and rotating components, are primarily wear parts that can be replaced at regular intervals. If wear occurs, this is evident at the first end of the feeder, where a liquid-tight connection to the water supply is to be established and where standing and rotating parts of the drive device adjoin each other. The packing rings, which seal this transition from fixed and rotating components as sealing elements, must be replaced in known systems in a maintenance-friendly manner with the boring bar drive installed in the steel frame of the decoking system.
Es ist Aufgabe der Erfindung, eine solche Antriebsvorrichtung für eine Bohrstange in ihrer Konstruktion zu vereinfachen und den Wechsel der Dichtungselemente wartungsfreundlicher und weniger aufwendig zu gestalten.It is an object of the invention to simplify the construction of such a drive device for a boring bar and to make the replacement of the sealing elements more maintenance-friendly and less expensive.
Diese Aufgabe wird durch eine Antriebsvorrichtung nach Anspruch l gelöst. Eine Antriebsvorrichtung mit einer Zuführung, die einen ersten und einen zweiten Abschnitt aufweist, erlaubt einen schnelleren und fehlerfreien Wechsel. Ein zweiter Abschnitt, der an die Bohrstange anschließt und kaum Verschleißerscheinungen zeigt, bleibt fest mit dem Getriebe und der Bohrstange verschraubt. Störungen die durch wiederholte Ein- griffe in diese Anlagenteile auftreten können, werden damit sicher vermieden.This object is achieved by a drive device according to claim 1. A drive device with a feed, which has a first and a second section, allows a faster and error-free change. A second section, which connects to the boring bar and shows hardly any signs of wear, remains firmly screwed to the gear and the boring bar. Faults that can occur as a result of repeated interventions in these parts of the system are thus reliably avoided.
Der erste Abschnitt der Zuführung ist durch eine einfache Verbindung lösbar und ansonsten sicher und flüssigkeitsdicht mit dem zweiten Abschnitt verbunden. Die Verbindung, insbesondere die Dichtungselemente zwischen dem ersten Abschnitt der Zufüh- rung und der Wasserversorgung, die Verschleiß ausgesetzt ist, muss für die Verwendung einer erfindungsgemäßen Bohrvorrichtung nicht geändert werden. Die Art der Verbindung zwischen Wasserversorgung und Zuführung ändert sich nicht notwendigerweise. Allerdings wird nun nur noch eine kompakte, komplette Baueinheit ausgetauscht.The first section of the feed is detachable by a simple connection and is otherwise securely and liquid-tightly connected to the second section. The connection, in particular the sealing elements between the first section of the feed and the water supply, which is exposed to wear, does not have to be changed for the use of a drilling device according to the invention. The type of connection between water supply and supply does not necessarily change. However, now only a compact, complete unit is replaced.
Der Vorteil des Tauschens einer kompakten, kompletten Baueinheit liegt darin, daß nun nicht mehr die Dichtungselemente bei eingebautem Bohrstangenantrieb unter räumlich schwierigen Bedingungen getauscht werden müssen. Vielmehr kann die Baueinheit, die aus dem ersten Abschnitt der Zuführung des Bohrstangenantriebs mit den verschlisse- nen Packungsringen besteht, ungestört gereinigt und in Stand gesetzt sowie mit neuen Packungsringen versehen werden. Die in Stand gesetzte Baueinheit steht dann für den nächsten Einsatz in einem Bohrstangenantrieb bereit. Da der Anschluss an den zweiten Abschnitt über eine verhältnismäßig einfache Verbindung erfolgt, kann die erf dungs- 5 gemäße Bohrvorrichtung in erheblich kürzerer Zeit in Stand gesetzt werden.The advantage of exchanging a compact, complete unit is that it is no longer necessary to replace the sealing elements when the boring bar drive is installed under spatially difficult conditions. Rather, the assembly that emerges from the first section of the feed of the boring bar drive with the worn packing rings are in place, cleaned and repaired undisturbed, and new packing rings are fitted. The repaired unit is then ready for the next use in a boring bar drive. Since the connection to the second section is made via a relatively simple connection, the drilling device according to the invention can be repaired in a considerably shorter time.

Genauso sieht eine Verschraubung nach einer bevorzugten Ausführungsform Mittel zum Ver- schrauben vor, die den ersten und den zweiten Abschnitt der Zuführung miteinander10 see the two sections clamping, to be designed as a screw connection or as a flange. A clamping connection preferably provides clamping means which connect the first and the second section of the feeder to one another. Likewise, a screw connection according to a preferred embodiment provides means for screwing together the first and the second section of the feed

Das die Zuführung und die Bohrstange in Rotation versetzende Getriebe wird bei Bohrvorrichtungen nach dem Stand der Technik üblicherweise individuell gefertigt, weil die 20 Auffassung vorherrschte, daß es sich um einen sehr speziellen Anwendungsfall handle, der besondere Maßnahmen bei der Konstruktion und Auslegung des Getriebes erfordere. Bei den Getrieben nach dem Stand der Technik werden die Getriebe von einem öl- gefüllten Gehäuse umschlossen.The gear that sets the feed and the boring bar in rotation is custom-made in drilling devices according to the prior art, because the prevailing view was that it was a very special application that required special measures in the construction and design of the gear. In the prior art gearboxes, the gearboxes are enclosed in an oil-filled housing.
25 Es ist als eigenständige erfinderische Leistung anzusehen, daß die erfindungsgemäße Bohrvorrichtung durch den konsequenten Einsatz von Standard-Bauteilen, die beispielsweise von Zulieferern katalogmäßig angeboten werden, in ihrem Aufbau vereinfacht wird. Durch die Verwendung von Standard-Bauteilen wird in der Regel auch die Betriebssicherheit der Vorrichtung erhöht, weil diese Bauteile in einer Vielzahl anderer25 It is to be regarded as an independent inventive achievement that the construction of the drilling device according to the invention is simplified through the consistent use of standard components, which are offered, for example, by suppliers. The use of standard components generally also increases the operational reliability of the device, because these components are used in a large number of others
30. Anwendungen bereits erprobt wurden. Außerdem wird der Preis der Bohrvorrichtung vorteilhaft verringert.30. Applications have already been tried. In addition, the price of the drilling device is advantageously reduced.
Es wird weiter als eigene erfinderische Leistung angesehen, für eine Bohrvorrichtung, die insbesondere in Decokinganlagen Verwendung findet, ein Getriebe vorzuschlagen, daß als offenes, lediglich gefettetes Zahnrad-Zahnkranz-Getriebe ausgebildet ist. Überraschenderweise haben sich solche Getriebe, die für Drehvorrichtungen bereits bekannt sind, als ausreichend robust für den Einsatz in Bohrvorrichtungen erwiesen. Die Wartung und Instandhaltung solcher Getriebe ist besonders einfach und schnell durchzuführen.It is also viewed as a separate inventive achievement for a drilling device which is used in particular in decoking systems to propose a gear that is designed as an open, only greased gear-ring gear. Surprisingly, such gears, which are already known for turning devices, have proven to be sufficiently robust for use in drilling devices. The maintenance and repair of such gearboxes is particularly simple and quick to carry out.
Eine der möglichen Ausführungsformen der Erfindimg wird in Fig. l näher beschrieben. Es zeigt:One of the possible embodiments of the invention is described in more detail in FIG. It shows:
Fig. i einen Längsschnitt durch eine erfindungsgemäße Antriebsvorrichtung für eine Bohrstange.Fig. I shows a longitudinal section through a drive device according to the invention for a boring bar.
Zu der erfindungsgemäßen Vorrichtung 2zum Antrieb der Bohrstange zählen die Zu- führung 4 mit einem ersten Anschluss 6 an die Wasserversorgung 8 und mit einem zweiten Anschluss 10 an die Bohrstange 12 sowie der Antrieb 14 für das Getriebe 16, mit dem die Zuführung 4 und die Bohrstange 12 im Betriebszustand in Rotation versetzt werden.The device 2 according to the invention for driving the boring bar includes the feed 4 with a first connection 6 to the water supply 8 and with a second connection 10 to the boring bar 12 as well as the drive 14 for the gear 16 with which the feed 4 and the boring bar 12 are set in rotation in the operating state.
Die Wasserversorgung 8, die hier nur ansatzweise dargestellt ist, ist in der Regel nach Art eines Schwanenhalses ausgebildet. Sie mündet in einem Flansch 18, an dem ein erster Abschnitt 20 der Zuführung 4 ansetzt. Die Verbindung mit dem ersten Abschnitt 20 wird durch einen ersten Anschluss 6 hergestellt. Der Anschluss 6 liegt mit einer Anlagefläche 22 an dem Flansch 18 an. Um die Verbindung flüssigkeitsdicht auszubilden, ist eine normgerechte Dichtung 24 zwischen dem Anschluss 6 und dem Flansch 18 vorgesehen.The water supply 8, which is only partially shown here, is generally designed in the manner of a gooseneck. It opens into a flange 18 on which a first section 20 of the feed 4 attaches. The connection to the first section 20 is established by a first connection 6. The connection 6 bears against the flange 18 with a contact surface 22. In order to make the connection liquid-tight, a standard-compliant seal 24 is provided between the connection 6 and the flange 18.
Der Anschluss 6 ist durch eine Verschraubung 26, die hier nur angedeutet ist, lösbar mit dem Flansch 18 verbunden. Der Anschluss 6 umgreift dichtende Packungen 32, die sich um den ersten Abschnitt 20 legen. Gegen den in der Zuführung 4 wirkenden Wasserdruck sind die Packungen 32 nach unten durch eine Halterung 30 mit Schrauben 28 lösbar befestigt. Um diese wirksame Abdichtung zwischen der Wasserversorgung 8, dem ortsfesten Anschluss 6 und dem im Betriebszustand rotierenden ersten Abschnitt 20 der Zuführung 4 zu gewährleisten, füllen mehrere dichtende Packungen 32 einen kreisringförmigen Hohlraum 34 zwischen dem Anschluss 6 und dem ersten Abschnitt 20 vollständig aus.The connection 6 is detachably connected to the flange 18 by a screw connection 26, which is only indicated here. The connection 6 encompasses sealing packs 32 which wrap around the first section 20. Against the water pressure acting in the feed 4, the packs 32 are detachably fastened downward by a holder 30 with screws 28. Around this effective seal between the water supply 8, the fixed connection 6 and the first section rotating in the operating state 20 to ensure the feed 4, a plurality of sealing packs 32 completely fill an annular cavity 34 between the connection 6 and the first section 20.
Der erste Abschnitt 20 ist über eine Klemme 36, die über Anlageflächen 38, 38a mit dem ersten Abschnitt im Eingriff steht, mit dem zweiten Abschnitt 40 verbunden. Eine Dichtung 42 ist zwischen beiden Abschnitten 20, 40 eingesetzt. Die Klemme 36 liegt über Anlageflächen 44, 44a am zweiten Abschnitt 40 an. Die Abschnitte 20, 40 sind an den einander zugewandten Flächen 46, 46a plan gestaltet und weisen an den äußeren Umfang lediglich die beschriebenen Anlageflächen 38, 38a und 44, 44a auf. Die Fertigung, die Montage und Demontage des ersten Abschnitts 20 erfordern also wenig Aufwand und Zeit.The first section 20 is connected to the second section 40 via a clamp 36 which engages with the first section via contact surfaces 38, 38a. A seal 42 is inserted between the two sections 20, 40. The clamp 36 abuts the second section 40 via contact surfaces 44, 44a. The sections 20, 40 are flat on the mutually facing surfaces 46, 46a and only have the described contact surfaces 38, 38a and 44, 44a on the outer circumference. The manufacture, assembly and disassembly of the first section 20 therefore require little effort and time.
Sind die Packungen 32 verschlissen so müssen sie ausgetauscht werden. Damit der Austausch einfach, sicher und schnell erfolgt, wird eine Baueinheit, die aus dem ersten Abschnitt 20, den Packungen 32 und dem Anschluss 6 zusammengesetzt ist, nach dem Lösen der Klemme 36 und dem Lösen des Anschlusses 6 aus der Antriebsvorrichtung 2 ausgebaut. Eine baugleiche Baueinheit, die mit neuen Packungen 32 ausgestattet ist, wird in die Antriebsvorrichtung 2 eingesetzt. Die Klemme 36 und der Anschluss 6 wer- den wieder abdichtend geschlossen. Die Antriebsvorrichtung 2 ist nach kurzem Stillstand wieder betriebsbereit.If the packs 32 are worn out, they must be replaced. In order for the exchange to be carried out simply, safely and quickly, a structural unit, which is composed of the first section 20, the packs 32 and the connection 6, is removed from the drive device 2 after the terminal 36 has been released and the connection 6 has been released. An identical structural unit, which is equipped with new packs 32, is inserted into the drive device 2. Terminal 36 and connection 6 are closed again in a sealing manner. The drive device 2 is ready for operation again after a brief standstill.
Der zweite Abschnitt 40 ist einteilig mit dem Anschluss 10 ausgebildet, an dem das Getriebe 16 ansetzt. Weiterer Bestandteil des Anschlusses 10 ist der Flansch 48, an dem die Bohrstange 12 verschraubt ist. Die Verschraubung 50 ist nur angedeutet. Die Umfangs- fläche 52 des Anschlusses 10, also das der Bohrstange 12 zugewandete Ende des zweiten Abschnitts 40, ist als Außen-Zahnkranz ausgebildet. Mit diesem Außen-Zahnkranz 52 steht ein Zahnrad 54 im Eingriff, daß im Betriebszustand durch den Antrieb 14 in Rotation versetzt wird.The second section 40 is formed in one piece with the connection 10, to which the gear 16 attaches. Another component of the connection 10 is the flange 48 to which the boring bar 12 is screwed. The screw connection 50 is only indicated. The peripheral surface 52 of the connection 10, that is to say the end of the second section 40 facing the boring bar 12, is designed as an external toothed ring. A gear 54 is in engagement with this external ring gear 52, which is set in rotation by the drive 14 in the operating state.
Der Antrieb 14 weist einen Motor 56 auf. Im vorliegenden Fall handelt es sich um einen Elektromotor. Es können aber auch hydraulische oder pneumatische Motoren Verwendung finden. Dem Motor 56 ist ein Getriebe 58 nachgeschaltet, dessen Ausgangs- Zahnrad 60 mit dem Zahnrad 54 im Eingriff steht. Der Außen-Zahnkranz 52, das Zahnrad 54 und das Ausgangs-Zahnrad 60 bilden das Getriebe 16. Der Außen-Zahnkranz 52 und die Zahnräder 54 und 60 sind als offenes, gefettetes Getriebe 16 ausgebildet. Ein geschlossenes Getriebegehäuse ist nicht erforderlich und damit entfällt auch das Erfor- dernis, große Mengen Getriebeöl einzusetzen. Die erfindungsgemäß vorgeschlagene Lösung des offenen Getriebes 16 ist besonders einfach und wartungsarm. Darüber hinaus ergibt sich der Vorteil, daß der Außenzahnkranz 52 nicht mehr für jede Zuführung 4, die als Verschleißteil regelmäßig zu wechseln ist, neu gefertigt werden muss.The drive 14 has a motor 56. In the present case, it is an electric motor. Hydraulic or pneumatic motors can also be used. A gear 58 is connected downstream of the motor 56, the output Gear 60 is engaged with gear 54. The outer ring gear 52, the gear 54 and the output gear 60 form the transmission 16. The outer ring gear 52 and the gears 54 and 60 are designed as an open, greased transmission 16. A closed gear housing is not necessary, which means that there is no need to use large quantities of gear oil. The solution of the open gear 16 proposed according to the invention is particularly simple and requires little maintenance. In addition, there is the advantage that the outer ring gear 52 no longer has to be manufactured for each feed 4, which is to be changed regularly as a wearing part.
Die Bauteile mit den Bezugszeichen 54, 56, 58 und 60 sind sämtlich Standard-Bauteile, die von Lieferanten katalogmäßig angeboten werden und die in zahlreichen anderen Anwendungen erprobt wurden.The components with the reference symbols 54, 56, 58 and 60 are all standard components which are offered by suppliers in the catalog and which have been tested in numerous other applications.
Ebenfalls im Bereich des Anschlusses ιo, also an dem der Bohrstange 12 zugewandten Ende des zweiten Abschnitts 40, sind ein Axiallager 62 und ein Radiallager 64 angeordnet. Diese Lager 62 und 64 nehmen die durch das Getriebe 16 in die Bohrvorrichtung 2 sowie die durch das Eigengewicht der Bohrvorrichtung 2 eingebrachten Lasten auf und gewährleisten eine ruhige Rotation der Bohrvorrichtung 2 im Betriebszustand.An axial bearing 62 and a radial bearing 64 are also arranged in the area of the connection 10, that is to say at the end of the second section 40 facing the boring bar 12. These bearings 62 and 64 absorb the loads introduced by the gear 16 into the drilling device 2 and the loads introduced by the weight of the drilling device 2 and ensure a smooth rotation of the drilling device 2 in the operating state.
Um die im Betriebszustand rotierende Zuführung 4 abzudecken, weist die Bohrvorrichtung 2 eine Laterne 66 auf, die die Verbindung von der Wasserzuführung 8 zur Getriebeeinheit 16 darstellt. Über die Laterne 66 wird der Bohrstangenantrieb montiert und gehalten. Die Laterne 66 ist einfach an- und abzubauen, da sie zum Wechseln des ersten Abschnitts 20 der Zuführung 4 stets entfernt werden muss. Sie weist iπfBereich der Packungen 32 ein Montagefenster auf, so daß vollständige Sicherheit des Betriebspersonals gewährleistet ist, wenn der Zustand der Packungen 32 -und damit das Ausmaß der Verschleißerscheinungen-, ggf. in unmittelbarer Nähe rotierender, unter Hochdruck stehender Bauteile, zu kontrollieren ist.In order to cover the feed 4 rotating in the operating state, the drilling device 2 has a lantern 66 which represents the connection from the water feed 8 to the gear unit 16. The boring bar drive is mounted and held via the lantern 66. The lantern 66 is easy to assemble and disassemble, since it must always be removed in order to change the first section 20 of the feeder 4. It has an assembly window in the area of the packs 32, so that complete safety of the operating personnel is guaranteed if the condition of the packs 32 - and thus the extent of the signs of wear - is to be checked, possibly in the immediate vicinity of rotating, high-pressure components.
Im Zusammenhang mit der vorliegenden Erfindung ist mehrfach die Verwendung von Dichtungen angesprochen worden. Es liegt auf der Hand, daß bei einer Bohrvorrichtung, die Wasser mit einem Druck von über 100 bar von der Wasserversorgung zu einem Werkzeug befördert, flüssigkeitsdicht auszubilden ist. Dichtungen sind deshalb an den Stellen vorzusehen, die nicht auf andere Weise flüssigkeitsdicht ausgebildet werden können, unabhängig davon, ob dies in der vorstehenden Beschreibung erwähnt wurde, oder nicht. The use of seals has been mentioned several times in connection with the present invention. It is obvious that a drilling device which conveys water at a pressure of over 100 bar from the water supply to a tool must be designed to be liquid-tight. Seals are therefore on the places that can not be made otherwise liquid-tight, regardless of whether this was mentioned in the above description or not.
