Abstract

The connecting part has a connecting plate between a reservoir container containing. a pump and an electric motor in the pressure generator. The connecting plate contains bores and valves corresponding. to the hydraulic circuit diagram. The connector part (2) is angled with arms of approximately equal length. Hollow bolts are used to attach the pressure generating unit (1) to the connecting part.

Description

Verbindungsstück zwischen einer Druckerzeugungseinheit und einem Drehantrieb.Connector between a pressure generating unit and one Rotary drive.

Drehantriebe werden in der Industrie u. a. zum Öffnen und Schliellen 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 Druckerzeugungsein­ heit, 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 drives are used in industry and a. to open and close Valves used. Hydraulically driven rotary drives are in the Usually supplied with hydraulic fluid from central pump stations. This has because of the possibility of leakage of the hydraulic lines considerable safety-related disadvantages and can cause problems of the pressure drop due to the line resistance. From these For reasons, it makes sense and is known to 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 drive to build, and only electrical power via a cable connect so that leaks in the hydraulic lines and a Pressure drop are excluded.

Darüberhinaus lassen sich dann mehrere Drehantriebe über die elektri­ schen Leitungen in einfacher Weise durch eine zentrale Steuerung über­ wachen und betätigen.In addition, several rotary drives can then be operated via the electri lines in a simple manner via a central control watch and press.

Nach dem Vorschlag der Erfindung ist zur Befestigung der Druckerzeu­ gungseinheit 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 Drehan­ trieb 5 kraftschlüssig verbunden. Zur Lageorientierung der Anschluß­ bohrungen 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 1d eingeschraubt sind. Mittig zwischen den Hohlschrauben 3 ist eine Entlüftungsbohrung 12 für den Vorrats­ behälter 1a vorgesehen, die durch einen Filter 13 verschlossen wird. Je nach Anordnung der Druckerzeugeungseinheit 1, werden die Hohl­ schrauben 3 entweder parallel oder um 90° gedreht zum Schenkel 2a des Verbindungsstückes 2 eingebaut.According to the proposal of the invention, an angular connector 2 is provided for fastening the printer unit 1 on the rotary drive 5 , in which the connection bores 7 a, 7 b, 7 c, 7 d are incorporated. The connector 2 is driven by a screw 6 with the rotary drive 5 non-positively. Centering pins 8 are provided for positional orientation of the connection bores 7 e, 7 f. Pressure generating unit and connecting piece are connected to each other by means of banjo bolts 3 and sealed to the outside by seals 9 , 10 . The banjo bolts 3 are screwed into threaded bushings 11 , which in turn are screwed into the connecting plate 1 d. In the middle between the banjo bolts 3 , a vent hole 12 for the storage container 1 a is provided, which is closed by a filter 13 . Depending on the arrangement of the pressure generating unit 1 , the hollow screws 3 are either parallel or rotated by 90 ° to the leg 2 a of the connector 2 installed.

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