Description

Antriebseinheit von Absperreinrichtungen, insbesondere Schiebern auf Tankschiffen Die Erfindung bezieht sich auf eine druckmittelbetätigte Antriebseinheit für die Spindel von Absperreinrichtungen, insbesondere Schiebern auf Tankschiffen, mit einem wahlweise in beiden Drehrichtungen antreibbaren hydraulischen Rotationsmotor, dessen Endstellung von einem sich in Abhängigkeit von der Stellung des Verschlußstücks bewegenden Nocken durch Schließen eines in der Antriebseinheit angeordneten Steuerventils für die Zuleitung gesteuert wird.Drive unit of shut-off devices, in particular slides Tankers The invention relates to a pressure medium-operated drive unit for the spindle of shut-off devices, especially gate valves on tankers, with a hydraulic rotary motor that can be driven in either direction of rotation, the end position of which depends on the position of the closure piece moving cam by closing a control valve arranged in the drive unit for the supply line is controlled.

Bei einer bekannten derartigen Antriebseinheit für Absperreinrichtungen auf Schiffen schaltet der Nokken das Steuerventil etwa eine halbe Spindelumdrehung vor der Endstellung ab, die dann erst durch Drehen eines Handrades eingestellt wird. Desgleichen muß die halbe Umdrehung in umgekehrter Richtung erst vorgenommen werden, ehe der hydraulische Rotationsmotor die weitere Betätigung des Verschlußstückes übernimmt. Diese bekannte Antriebseinheit ist daher nicht für eine Fernsteuerung geeignet.In a known drive unit of this type for shut-off devices on ships, the cam switches the control valve about half a spindle turn before the end position, which is then only set by turning a handwheel. Likewise, half a turn in the opposite direction must first be made before the hydraulic rotary motor continues to operate the locking piece takes over. This known drive unit is therefore not suitable for remote control suitable.

Der Erfindung liegt daher die Aufgabe zugrunde, eine fernsteuerbare druckmittelbetätigte Antriebseinheit zu schaffen, die darüber hinaus ohne Abänderung bei verschiedenen Arten und Größen von Absperreinrichtungen und für verschiedene Anwendungsfälle einsetzbar ist. Dieser allgemeinen Aufgabenstellung ordnet sich die spezielle Aufgabenstellung unter, daß jede Endstellung oder mindestens eine davon genau einstellbar sein muß, damit der Motor das Verschlußstück in mindestens eine genau definierte Stellung (dicht geschlossen bzw. ganz geöffnet bzw. gegebenenfalls eine bestimmte Zwischenstellung) bringen und aus dieser wieder herausfahren kann. Zum letzteren Zweck muß der Motor in beiden Richtungen arbeiten können.The invention is therefore based on the object of providing a remotely controllable to create pressure medium-actuated drive unit that, moreover, without modification for different types and sizes of shut-off devices and for different Use cases can be used. This general task is organized the special task under that each end position or at least one of which it must be precisely adjustable so that the motor has the locking piece in at least a precisely defined position (tightly closed or fully open or possibly a certain intermediate position) and can move out of this again. For the latter purpose, the motor must be able to work in both directions.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß das Steuerventil durch ein Rückschlagventil überbrückt ist, daß der Nocken innerhalb der Antriebseinheit angeordnet ist und seine Bewegung unmittelbar vom Antriebsmotor erhält, und daß die Stellung des Nockens relativ zum Betätigungsglied des Steuerventils einstellbar ist. Durch die Überbrückung des Steuerventils durch das Rückschlagventil kann der Antriebsmotor bei Umkehrung des Drackmittelstromes sofort in umgekehrter Richtung anfahren. Die Anordnung des Nockens innerhalb der Antriebseinheit ermöglicht es, daß ein und dieselbe Antriebseinheit an jedes beliebige Ventil usw. angeschlossen werden kann, ohne daß am Ventil usw. besondere Abänderungen vorgenommen werden müssen. Daß der Nocken seine Bewegung unmittelbar vom Antriebsmotor erhält, hat denselben Sinn. Dasselbe gilt für die Einstellbarkeit des Nockens relativ zum Betätigungsglied des Steuerventils. Denn wenn etwa die Antriebseinheit gemäß der Erfindung an der Spindel eines speziellen Schiebers eines Tankschiffes angebracht und diese beispielsweise in die gewünschte Offenstellung gebracht ist, braucht man lediglich den Nocken relativ zum Betätigungsglied so einzustellen, daß der Nocken das Betätigungsglied gerade in der gewünschten Schaltstellung betätigt. Auf diese Weise können verschiedenartigste Absperreinrichtungen präzise in der gewünschten Weise von Ferne gesteuert werden.This object is achieved according to the invention in that the control valve is bridged by a check valve that the cam is within the drive unit is arranged and receives its movement directly from the drive motor, and that the position of the cam is adjustable relative to the actuator of the control valve is. By bridging the control valve with the check valve, the Drive motor immediately in reverse direction when the fluid flow is reversed approach. The arrangement of the cam within the drive unit enables that one and the same drive unit is connected to any valve, etc. can be made without special modifications to the valve, etc. The fact that the cam receives its movement directly from the drive motor has the same effect Sense. The same applies to the adjustability of the cam relative to the actuator of the control valve. Because if about the drive unit according to the invention on the Spindle of a special slide of a tanker attached and this for example is brought into the desired open position, you only need the cam relative to adjust the actuator so that the cam straight the actuator operated in the desired switching position. In this way, the most varied Shut-off devices can be controlled remotely precisely in the desired manner.

Die Erfindung wird im folgenden an Hand schematischer Zeichnungen an zwei Ausführungsbeispielen näher erläutert.The invention is described below with reference to schematic drawings explained in more detail using two exemplary embodiments.

F i g. 1 zeigt die wesentlichen mechanischen Teile einer Antriebseinheit gemäß der Erfindung im Längsschnitt; F i g. 2 zeigt die hydraulische Anordnung derselben Antriebseinheit, und F i g. 3 zeigt eine spezielle Ausführungsform der Erfindung.F i g. 1 shows the essential mechanical parts of a drive unit according to the invention in longitudinal section; F i g. 2 shows the hydraulic arrangement of the same Drive unit, and FIG. 3 shows a specific embodiment of the invention.

In F i g. 1 ist ein hydraulischer Rotationsmotor 1 schematisch dargestellt, der von einer Grundplatte 2 unterstützt ist und mit dem Vorgelege 3 gekuppelt ist. Die treibende Welle 4 des Vorgeleges ragt auf der Grundplatte 2 nach außen, so daß sie mit der Spindel des nicht gezeigten Schiebers gekuppelt werden kann. Auf der Grundplatte 2 ist ein Gehäuse 5 abdichtend befestigt, das den hydraulischen Rotationsmotor 1 sowie die mit diesem zusammenwirkenden Teile nach außen dicht abkapselt, und mit Öl oder einer anderen die Teile gegen Einwirkungen von außen schützenden Flüssigkeit gefüllt ist.In Fig. 1 a hydraulic rotary motor 1 is shown schematically, which is supported by a base plate 2 and is coupled to the back gear 3. The driving shaft 4 of the countershaft protrudes outward on the base plate 2, so that it can be coupled to the spindle of the slide, not shown. On the Base plate 2 is sealingly attached to a housing 5, which houses the hydraulic rotary motor 1 and the parts cooperating with this tightly encapsulated to the outside, and with Oil or another liquid that protects the parts against external effects is filled.

Eine mit dem Motor 1 verbundene Gewindespindel ( ragt durch das Gehäuse 5 nach außen und ist an ihrem außenliegenden Ende mit einem Handrad 7 versehen, so daß die Verstellung des Schiebers gegebenenfalls auch mittels Hand erfolgen kann.A threaded spindle connected to the motor 1 (protrudes through the housing 5 to the outside and is at its outer end with a handwheel 7 Mistake, so that the slide can also be adjusted by hand if necessary.

In der Grundplatte 2 sind Anschlußstutzen 8 für die Speiseleitungen 9 des umkehrbaren Motors vorgesehen. Innerhalb des Gehäuses 5 führen Leitungen 10 und 11 von den Anschlußstutzen 8 jeweils zu einem Steuerventil 12 bzw. 13, die in einem gegenseitigen Abstand in dem Gehäuse 5 fest angeordnet sind. Von den Steuerventilen führen Leitungen 15, 16 zu dem umkehrbaren Hydraulikmotor 1.In the base plate 2 there are connecting pieces 8 for the feed lines 9 of the reversible motor is provided. Lines 10 run inside the housing 5 and 11 from the connection piece 8 each to a control valve 12 and 13, respectively, which are shown in are fixedly arranged at a mutual distance in the housing 5. From the control valves lines 15, 16 lead to the reversible hydraulic motor 1.

Etwa parallel zu der Spindel 6 ist eine weitere Gewindespindel 18 drehbar gelagert, die über Zahnräder 19, 20 vom hydraulischen Rotationsmotor synchron angetrieben werden kann. Auf der Gewindespindel 18 läuft eine Wandermutter 21, deren Stellung auf der Gewindespindel 18 jeweils der Stellung des Verschlußstücks entspricht. Die Wandermutter wirkt mit Schaltfühlern 25, 26 der Steuerventile 13 bzw. 12 zusammen, um bei Erreichen einer bestimmten Stellung die Ströme des Antriebsdruckmittels zu dem Hydraulikmotor 1 zunächst zu drosseln und dann vollständig abzuschalten. Another threaded spindle 18 is rotatably mounted approximately parallel to the spindle 6 and can be driven synchronously by the hydraulic rotary motor via gears 19, 20. A traveling nut 21 runs on the threaded spindle 18 , the position of which on the threaded spindle 18 corresponds in each case to the position of the closure piece. The traveling nut interacts with switch sensors 25, 26 of the control valves 13 and 12, respectively, in order to initially throttle the flows of the drive pressure medium to the hydraulic motor 1 and then to switch them off completely when a certain position is reached.

Auf der Spindel 6 läuft eine weitere Wandermutter 30, die über einen Arm 31 und eine Rolle die Winkellage eines Hebels 32 je nach Stellung des Verschlußstücks steuert. Zu diesem Zweck greift der Arm 31 der Wandermutter in eine Längsnut 33 des Hebels ein. Am oberen Ende des Hebels 32 ist ein Arm 35 eingelenkt, der mit seinem anderen Ende an den Zeiger 36 eines Stellungsanzeigers 37 angreift. Der Stellungsanzeiger 36 wirkt mit einer außerhalb des Gehäuses 5 liegenden Skala 38 zusammen.On the spindle 6 another traveling nut 30 runs, which has a Arm 31 and a role the angular position of a lever 32 depending on the position of the locking piece controls. For this purpose, the arm 31 of the traveling nut engages in a longitudinal groove 33 of the lever. At the upper end of the lever 32, an arm 35 is pivoted, which with its other end engages the pointer 36 of a position indicator 37. The position indicator 36 cooperates with a scale 38 located outside the housing 5.

Selbstverständlich können die beiden Wandermuttern 21 und 30 durch eine gemeinsame Mutter oder durch ein anderes durch den Hydraulikmotor verstellbares Nockenglied ersetzt werden.Of course, the two hiking nuts 21 and 30 can go through a common nut or another adjustable by the hydraulic motor Cam member to be replaced.

Da in vielen Fällen eine Fernanzeige für die Schieberstellung gewünscht wird, um beispielsweise von der Schiffsbrücke aus die Stellungen der verschiedenen Schieber überwachen und gegebenenfalls steuern zu können, ist mit dem unteren Ende des Hebels 32, der bei 40 auf einer festen Platte 41 angelenkt ist, ein kurzer Hebelarm 42 drehfest verbunden. Dieser nimmt also an den Winkelbewegungen des Hebels 32 teil. Der Hebel 42 steht über Verbindungsglieder 44 mit dem Geber 46 einer hydraulischen Fernanzeigeeinrichtung in Verbindung, deren Geberleitungen 47, 48 zu Anschlußstutzen 49 in der Grundplatte 3 führen. An diese Anschlußstücke können die hydraulischen Fernanzeigeleitungen 50, 51 angeschlossen werden.As a remote display for the slide position is required in many cases is, for example, from the ship's bridge from the positions of the various Being able to monitor slides and, if necessary, control them is at the lower end of the lever 32, which is articulated at 40 on a fixed plate 41, is a short lever arm 42 non-rotatably connected. This therefore takes part in the angular movements of the lever 32. The lever 42 is via connecting members 44 with the transmitter 46 of a hydraulic Remote display device in connection, its encoder lines 47, 48 to connecting pieces 49 in the base plate 3. The hydraulic Remote display lines 50, 51 are connected.

In F i g. 2 ist die Einschaltung der Vorrichtung gemäß der Erfindung in die Hydraulikanlage eines Tankschiffes schematisch angedeutet. Hierbei sind für die gleichen Teile die geltenden Bezugsziffern wie in F i g.1 verwendet. Man erkennt in dem durch strichpunktierte Linie 50 umrahmten Feld die Teile der Vorrichtung gemäß der Erfindung, die in dem gemeinsamen Gehäuse 5 untergebracht sind. Die beiden Speiseleitungen 9 des Hydraulikmotors sind über ein handbetätigtes Steuerventil 51, das außerhalb des Gehäuses 5, beispielsweise an einer zentralen Kommandostelle, angeordnet sein kann, mit der Druckleitung 52 bzw. der Rücklaufleitung 53 eines hydraulischen Speisesystems verbunden.In Fig. 2, the connection of the device according to the invention in the hydraulic system of a tanker is indicated schematically. The reference numbers that apply to the same parts as in FIG. 1 are used here. The parts of the device according to the invention which are accommodated in the common housing 5 can be seen in the field framed by the dash-dotted line 50. The two feed lines 9 of the hydraulic motor are connected to the pressure line 52 or the return line 53 of a hydraulic feed system via a manually operated control valve 51, which can be arranged outside the housing 5, for example at a central command post.

Den beiden mechanischen Anschlagventilen 12 und 13 sind außerdem noch Rückschlagventile 54 bzw. 55 zugeordnet. Diese Ventile sind notwendig, weil beispielsweise beim Umschalten des Antriebs auf »Öffnen« die frühere Zulaufleitung Ablaufleitung wird. Diese Leitung ist jedoch noch durch den zugehörigen Endschalter gesperrt, so daß der Rücklauf über das Rückschlagventil erfolgen muß.The two mechanical stop valves 12 and 13 are also still Check valves 54 and 55 assigned. These valves are necessary because, for example when the drive is switched to »open«, the former supply line drain line will. However, this line is still blocked by the associated limit switch, so that the return must take place via the check valve.

Um eine einfache und genaue Einstellungsmöglichkeit der Wandermutter zu erhalten, kann die Anordnung nach wie in F i g. 3 getroffen werden. In dieser Figur ist der obere Teil und der untere einer von dem Hydraulikmotor angetriebenen Gewindespindel 100 dargestellt, auf der sich zwei Wandermuttern 101 und 102 bewegen können. Während das obere Anschlagventil nicht dargestellt ist, ist in der unteren Hälfte der F i g. 3 das fest eingebaute untere Anschlagventil 103 angedeutet. Der Antrieb für die Spindel 100 ist lediglich durch die untere Begrenzungslinie 104 angedeutet.In order to obtain a simple and precise adjustment option for the traveling nut, the arrangement can be as shown in FIG. 3 are taken. This figure shows the upper part and the lower part of a threaded spindle 100 driven by the hydraulic motor, on which two traveling nuts 101 and 102 can move. While the upper stop valve is not shown, the lower half of FIG. 3 the permanently installed lower stop valve 103 is indicated. The drive for the spindle 100 is only indicated by the lower boundary line 104.

Jede Wandermutter 101 bzw. 102 ist mit mehreren in Umfangsrichtung verteilten und sich in Achsrichtung der Spindel 100 erstreckenden Schlitzen 105 versehen. Mit diesen Schlitzen wirkt eine Schiene 106 zusammen, die sich parallel zu der Spindel 100 erstreckt und im Bereich des unteren Endes an einer Stütze 107 derart angelenkt ist, daß die Schiene aus der in F i g. 3 in ausgezogenen Linien dargestellten Stellung in die gestrichelt dargestellte Stellung gekippt werden kann. Am oberen Ende weist die Schiene 106 eine Ausnehmung 108 auf, mit der die Schiene mit Hilfe einer Flügelmutter 109 an einer oberen festen Stütze 110 so festgelegt werden kann, daß sich die Kante 111 der Schiene im Eingriff mit jeweils einem Schlitz 105 der Wandermuttern 101 und 102 befindet.Each traveling nut 101 or 102 is provided with a plurality of slots 105 distributed in the circumferential direction and extending in the axial direction of the spindle 100 . A rail 106 cooperates with these slots, which extends parallel to the spindle 100 and is articulated to a support 107 in the region of the lower end in such a way that the rail consists of the arrangement shown in FIG. 3 can be tilted in the position shown in solid lines in the position shown in dashed lines. At the upper end, the rail 106 has a recess 108 with which the rail can be fixed to an upper fixed support 110 with the aid of a wing nut 109 so that the edge 111 of the rail engages with a slot 105 each of the traveling nuts 101 and 102 is located.

Zum Einstellen des genauen Zeitpunkts der Betätigung der Anschlagventile 103 ist es bei dieser Anordnung lediglich notwendig, die Schiene 106 in die gekippte Stellung zu bringen, worauf jede Wandermutter im gewünschten Maße so weit verdreht werden kann, wie dies zur Einstellung notwendig ist. Es ist lediglich dafür zu sorgen, daß sich jeweils ein Schlitz 105 der Wandermutter in der eingestellten Stellung in der Schwenkebene der Schiene 106 befindet, damit deren Kante zum Festlegen der Mutter in diese Schlitze eingreifen kann. Mit dieser Anordnung läßt sich eine sehr genaue Einstellung auf einfache Weise erreichen.In order to set the exact time of actuation of the stop valves 103, it is only necessary in this arrangement to bring the rail 106 into the tilted position, whereupon each traveling nut can be turned to the desired extent as far as is necessary for the adjustment. It is only necessary to ensure that in each case one slot 105 of the traveling nut is in the set position in the pivot plane of the rail 106 so that its edge can engage in these slots to fix the nut. With this arrangement, very precise adjustment can be achieved in a simple manner.

Um für die Stellungsanzeige des Schiebers die Notwendigkeit einer besonderen Abdichtung im Bereich des die Gehäusewand durchdringenden Zeigers zu vermeiden, kann sich die Anzeigeskala auch in einem besonderen Ansatz des Gehäuses parallel zu den Spindelachsen erstrecken und mit einer der Wandermuttern ein radial in diesem Ansatz ragender Zeiger verbunden sein, der an den Bewegungen der Wandermutter in axialer Richtung teilnimmt.In order for the position indicator of the slide the need for a special sealing in the area of the pointer penetrating the housing wall the display scale can also be avoided in a special approach to the housing extend parallel to the spindle axes and with one of the traveling nuts a radial in this approach protruding pointer be connected to the movements of the wandering nut participates in the axial direction.
