Description
Die Erfindung betrifft ein Verfahren zum Betrieb eines elektrohydraulischen Türantriebes mit einem Druckspeicher und einer hydraulischen Pumpeneinheit.The The invention relates to a method for operating an electrohydraulic door drive with a pressure accumulator and a hydraulic pump unit.
Elektrohydraulische Türantriebe besitzen in der Regel eine Feder als mech. Energiespeicher für die Schließung einer Tür, welche sowohl im Normalbetrieb als auch in einem Gefahrenfall (z. B. Brand) die Tür schließt. Der mechanische Energiespeicher wird bei jeder Öffnungsbewegung der Tür gespannt und entspannt sich beim Schließen der Tür. Für das Spannen des mechanischen Energiespeichers wird aber bei jedem Öffnungsvorgang der Tür eine zusätzliche Energie benötigt, was zwangsläufig zu einer entsprechend großen Auslegung des Antriebsaggregates führt.Battery powered door drives usually have a spring as mech. Energy storage for the closure of a Door, which both in normal operation and in a hazardous situation (eg fire) the Door closes. Of the mechanical energy storage is stretched with each opening movement of the door and relaxes when closing the door. For clamping However, the mechanical energy storage is at every opening process the door an additional Energy needed which inevitably to a correspondingly large Design of the drive unit leads.
Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, eine Betriebsweise für einen elektrohydraulischen Türantrieb mit mechanischem Energiespeicher und einer hydraulischen Pumpeneinheit anzugeben, bei welcher auf das permanente Spannen des mechanischen Energiespeichers verzichtet werden kann.The It is therefore an object of the present invention to provide a mode of operation for an electrohydraulic door drive with mechanical energy storage and a hydraulic pump unit specify in which on the permanent tightening of the mechanical Energy storage can be dispensed with.
Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruchs 1.The solution This object is achieved by the features of claim 1.
Erfindungsgemäß weist das Verfahren zum Betrieb eines elektrohydraulischen Türantriebs mit einem Druckspeicher und einer hydraulischen Pumpeneinheit folgende Schritte auf:
- – der Druckspeicher wird nur einmal gespannt, und zwar in einem Zustand, in dem der Türflügel nicht mittels der hydraulischen Pumpeneinheit bewegt wird,
- – im Normalbetrieb wird ein mit dem Türantrieb verbundener Türflügel ausschließlich mittels der hydraulischen Pumpeneinheit geöffnet bzw. geschlossen, wobei in beiden Bewegungsrichtungen der Druckspeicher geschlossen bleibt,
- – in einem Gefahrenfall wird die Tür mittels der im Druckspeicher gespeicherten Energie geschlossen.
- – die Vorspannung des Druckspeichers wird überwacht, und
- – sollte eine Verringerung der im Druckspeicher vorliegenden Vorspannung erkannt worden sein, wird der Druckspeicher erneut gespannt bzw. nachgespannt.
- The pressure accumulator is tensioned only once, in a state in which the door leaf is not moved by means of the hydraulic pump unit,
- In normal operation, a door leaf connected to the door drive is opened or closed exclusively by means of the hydraulic pump unit, the pressure reservoir remaining closed in both directions of movement,
- - In case of danger, the door is closed by means of the energy stored in the pressure accumulator.
- - The bias of the accumulator is monitored, and
- - If a reduction of the present in the pressure accumulator bias has been detected, the pressure accumulator is again stretched or tightened.
Aufgrund dieser Arbeitsweise wird der Druckspeicher nur einmal gespannt. Danach kann über die hydraulische Pumpeneinheit die Bewegung der Tür in Öffnungs- und Schließrichtung nur unter Überwindung der Trägheiten und Reibungen erfolgen. Eine permanente Spannung des Druckzylinders entfällt. Folglich kann auch das Antriebsaggregat deutlich kleiner und kostengünstiger ausgelegt werden.by virtue of In this way, the pressure accumulator is tensioned only once. After that can over the hydraulic pump unit controls the movement of the door in opening and closing direction only under overcoming the sluggishness and rubbing done. A permanent tension of the printing cylinder is eliminated. consequently can also drive unit significantly smaller and cheaper be interpreted.
Die Unteransprüche haben vorteilhafte Weiterbildungen der Erfindung zum Inhalt.The under claims have advantageous developments of the invention to the content.
Der Druckspeicher wird vorzugsweise erstmals bei der Inbetriebnahme des Türantriebes gespannt. Er bleibt dann während des normalen Betriebs des Türantriebes in der gespannten Stellung. Erst in einem Gefahrenfall, z. B. einem Brand, wird der Druckspeicher freigegeben, so dass die Tür auch bei einem Stromausfall mit Hilfe der im Druckspeicher vorhandenen Energie geschlossen werden kann.Of the Accumulator is preferably first time at startup of the door drive curious; excited. He then stays during the normal operation of the door drive in the cocked position. Only in a danger, z. B. one Fire, the pressure accumulator is released, so that the door also at a power failure with the help of existing energy in the accumulator can be closed.
Nach einem Gefahrenfall wird der Druckspeicher nach einer bevorzugten Weiterbildung erneut gespannt, um bis zu einem erneuten Gefahrenfall gespannt zu bleiben.To In a hazardous situation, the accumulator is a preferred Training again tense, up to a new hazard to stay curious.
Damit bei einer möglichen Leckage eine Entspannung des Druckspeichers erkannt wird, ist nach einer vorteilhaften Ausgestaltung vorgesehen, dass die Spannung des Druckspeichers überwacht wird und der Druckspeicher – z. B. bei Leckagen – erneut gespannt bzw. nachgespannt werden kann. Die Überwachung des Druckspeichers kann über eine Erkennung eines Stromanstiegs zum Ende der Öffnungsbewegung der Tür erfolgen. Wenn nämlich das Antriebsaggregat zusätzlich zur Öffnungsbewegung der Tür auch noch den Druckspeicher spannen muss, wird ein höherer Strom benötigt. Diese höhere Stromaufnahme stellt somit ein Signal für eine Entspannung des Druckspeichers dar.In order to at a possible Leakage a relaxation of the accumulator is detected is after a provided advantageous embodiment that monitors the voltage of the pressure accumulator is and the accumulator - z. B. leakage - again tense or can be re-tensioned. Monitoring the pressure accumulator can over a detection of a current increase at the end of the opening movement of the door done. If indeed the drive unit in addition for the opening movement of Door too still has to tension the accumulator, a higher current is needed. These higher power consumption thus provides a signal for a relaxation of the pressure accumulator.
Vorteilhafterweise kann das Spannen des Druckspeichers unabhängig von einer Bewegung der Tür erfolgen. Dies hat den Vorteil, dass das Antriebsaggregat entweder nur die Tür bewegt oder den Druckspeicher spannt. Bei herkömmlichen Türschließern dagegen muss das Antriebsaggregat bei der Öffnungsbewegung nicht nur die Tür bewegen, sondern zusätzlich auch noch den Druckspeicher spannen. Folglich kann das Antriebsaggregat bei dem erfindungsgemäßen Verfahren kleiner ausgebildet werden, da es nicht mehr so viel Kraft aufbringen muss.advantageously, the clamping of the pressure accumulator can be independent of a movement of the door. This has the advantage that the drive unit either only the Door moves or tensioning the accumulator. For conventional door closers on the other hand, the drive unit during the opening movement not just the door move, but in addition also tension the accumulator. Consequently, the drive unit in the method according to the invention be formed smaller, since it does not muster so much power got to.
Da beim erfindungsgemäßen Verfahren die Tür sowohl in Öffnungs- wie auch in Schließrichtung ausschließlich von dem Antriebsaggregat bewegt wird, ist nach einer bevorzugten Weiterbildung vorgesehen, dass eine in zwei Drehrichtungen antreibbare Pumpe verwendet wird. In der einen Drehrichtung der Pumpeneinheit wird somit die Tür geöffnet, während sie in der anderen Drehrichtung der Pumpeneinheit geschlossen wird.There in the method according to the invention the door both in opening as well as in the closing direction exclusively by the drive unit is moved, according to a preferred embodiment provided that uses a drivable in two directions of rotation pump becomes. In one direction of rotation of the pump unit is thus the Door open while she is closed in the other direction of rotation of the pump unit.
In einem Gefahrenfall wird der Druckspeicher vorteilhafterweise mittels eines Magnetventils freigegeben. Als mechanischer Energiespeicher kann vorzugsweise eine Feder verwendet werden.In a hazardous situation, the Druckspei cher advantageously released by means of a solenoid valve. As a mechanical energy storage, preferably a spring can be used.
