Description

-3-Beschreibung -3-Description

Drehantriebe werden in der Industrie u.a. zum Öffnen und Schließen von Ventilen eingesetzt. Hydraulisch angetriebene Drehantriebe werden in der Regel von zentralen Pumpenstationen mit Druckflüssigkeit versorgt.Dieses hat wegen der Möglichkeit des Undichtwerdens der Hydraulikleitungen erhebliche sicherheitstechnische Nachteile und kann zu Problemen wegen des Druckabfalles, aufgrund des Leitungswiderstandes,führen. Aus diesen Gründen ist es sinnvoll und bekannt die hydraulische Druckerzeugungseinheit, bestehend aus dem Vorratsbehälter für die Druckflüssigkeit, der Pumpe, dem Elektromotor und der Anschlußplatte, möglichst dicht an den Drehantrieb heranzubauen, und nur elektrischen Strom über ein Kabel anzuschließen, sodaß Undichtigkeiten der Hydraulikleitungen und ein Druckabfall ausgeschlossen sind.Rotary actuators are used in industry to open and close valves, among other things. Hydraulically driven rotary actuators are usually supplied with hydraulic fluid from central pump stations. This has significant safety disadvantages due to the possibility of the hydraulic lines becoming leaky and can lead to problems due to the pressure drop due to the line resistance. For these reasons, it is sensible and well known to install the hydraulic pressure generation unit, consisting of the reservoir for the hydraulic fluid, the pump, the electric motor and the connection plate, as close as possible to the rotary actuator and to only connect electrical power via a cable, so that leaks in the hydraulic lines and a pressure drop are excluded.

Darüberhinaus lassen sich dann mehrere Drehantriebe über die elektrischen Leitungen in einfacher Weise durch eine zentrale Steuerung überwachen und betätigen.In addition, several rotary actuators can then be easily monitored and operated via the electrical cables using a central control system.

Nach dem Vorschlag der Erfindung ist zur Befestigung der Druckerzeugungseinheit 1 am Drehantrieb 5 ein winkelförmiges Verbindungsstück 2 vorgesehen, in das die Anschlußbohrungen 7a,7b,7c,7d eingearbeitet sind. Das Verbindungsstück 2 wird mittels einer Schraube 6 mit dem Drehantrieb 5 kraftschlüssig verbunden. Zur Lageorientierung der Anschlußbohrungen 7e, 7f sind Zentrierstifte 8 vorgesehen. Druckerzeugungseinheit und Verbindungsstück werden mittels Hohlschrauben 3 mit einander verbunden und durch Dichtungen 9,10 nach außen hin abgedichtet. Die Hohlschrauben 3 werden in Gewindebuchsen 11 eingeschraubt, die wiederum in die Anschlußplatte Id eingeschraubt sind. Mittig zwischen den Hohlschrauben 3 ist eine Entlüftungsbohrung 12 für den Vorratsbehälter la vorgesehen, die durch einen Filter 13 verschlossen wird. Je nach Anordnung der Druckerzeugeungseinheit 1, werden die Hohlschrauben 3 entweder parallel oder um 90° gedreht zum Schenkel 2a des Verbindungsstückes 2 eingebaut.According to the proposal of the invention, an angle-shaped connecting piece 2 is provided for fastening the pressure generating unit 1 to the rotary drive 5, into which the connection holes 7a, 7b, 7c, 7d are machined. The connecting piece 2 is connected to the rotary drive 5 in a force-locking manner by means of a screw 6. Centering pins 8 are provided for the positional orientation of the connection holes 7e, 7f. The pressure generating unit and connecting piece are connected to one another by means of hollow screws 3 and sealed to the outside by seals 9, 10. The hollow screws 3 are screwed into threaded bushings 11, which in turn are screwed into the connection plate Id. In the middle between the hollow screws 3 there is a vent hole 12 for the storage container la, which is closed by a filter 13. Depending on the arrangement of the pressure generation unit 1, the hollow screws 3 are installed either parallel or rotated by 90° to the leg 2a of the connecting piece 2.

Im Verbindungsstück 2 ist ein Öffnungsventil 4 zum Kurzschließen der Drehantriebsdruckräume, wenn dieser im Notfall manuell gedreht werden muß, vorgesehen.An opening valve 4 is provided in the connecting piece 2 for short-circuiting the rotary drive pressure chambers if it has to be turned manually in an emergency.
