Description
Die Erfindung betrifft eine hydraulische Steuervorrichtung der im Oberbegriff des Anspruchs 1 angegebenen Art.The The invention relates to a hydraulic control device in the preamble of claim 1 specified type.
Derartige hydraulische Steuervorrichtungen werden beispielsweise in stationären Kränen oder Mobilkränen und bei anderen Hebezeugen mit mehreren zu bewegenden Komponenten verwendet, um Arbeitsgeschwindigkeit und Richtung zumindest eines Hydroverbrauchers über das Wegesteuerventil zu steuern. Als Druckquelle dient z.B. eine Regelpumpe, deren Fördermenge mittels des lastdruckabhängigen Steuerdrucks im Lastdrucksteuerkreis an den jeweiligen Bedarf angepasst wird. Eine Regelpumpe speist jedoch in abgeregeltem Betriebszustand einen Grunddruck zwischen 15 und 30 Bar ein. Bei einer Not-Aus-Betätigung der Steuervorrichtung wird zwar bei noch verstelltem Wegesteuerventil die Regelpumpe abgeregelt; der Grunddruck kann jedoch noch ausreichen, um über das Wegesteuerventil den Hydroverbraucher zu verstellen, was zu einer Gefahrensituation führen kann.such hydraulic control devices are used, for example, in stationary cranes or mobile cranes and Used on other hoists with multiple components to move about working speed and direction of at least one hydraulic consumer over the Control directional control valve. As a pressure source, e.g. a control pump, their delivery rate by means of the load pressure dependent Control pressure in the load pressure control circuit adapted to the respective needs becomes. A control pump feeds, however, in a regulated operating state a base pressure between 15 and 30 bar. In an emergency stop operation of Control device is indeed in still adjusted directional control valve the control pump is regulated; but the basic pressure may still be enough to over the directional control valve the hydraulic consumer to adjust what to lead to a dangerous situation can.

Der Erfindung liegt die Aufgabe zugrunde, eine hydraulische Steuervorrichtung der eingangs genannten Art mit einem kostengünstigen, baulich einfachen und funktionssicheren Not-Aus-Abschaltsystem weiterzubilden.Of the Invention is based on the object, a hydraulic control device of the type mentioned with a cost, structurally simple and functionally reliable emergency shutdown system.
Die gestellte Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.The Asked object is achieved with the features of claim 1.
Die beiden 2/2-Wegeventile (ein Magnetventil und ein gegen Federkraft druckvorgesteuertes Ventil) sind baulich einfach, kostengünstig und kompakt. Im Normalbetrieb wird das Trennventil nicht über das Not-Aus-Magnetschaltventil in der Durchgangsstellung gehalten, sondern über den vom Förderdruck der Druckquelle abgeleiteten Vorsteuerdruck. Das Not-Aus-Magnetschaltventil ist im Normalbetrieb bestromt und in der Absperrstellung, so dass der Vorsteuerdruck, der das Trennventil zur Durchgangsstellung beaufschlagt, nur die Kraft der Feder des Trennventils zu überwinden hat. Die permanente Verbindung der Federkammer zum Rücklauf verhindert, dass das Trennventil ungewollt absperrt oder abdrosselt. Bei Not-Aus wird das Not-Aus-Magnetschaltventil entregt und in seine Durchgangstellung geschaltet, so dass der dann parallel zur Feder wirkende Steuerdruck zuverlässig die Absperrstellung des Trennventils einstellt und hält. Die Blendeneinrichtung zwischen der Federkammer und dem Rücklauf ermöglicht einen permanenten Abfluss an Druckmittel, ohne die Absperrstellung des Trennventils zu gefährden. Bei einer neuerlichen Umschaltung in den Normalbetrieb kann durch die Blendeneinrichtung ein gegebenenfalls unerwünschtes schlagartiges Umschalten (Druckstoß) des Trennventils vermieden werden.The two 2/2-way valves (one solenoid valve and one against spring force pressure controlled valve) are structurally simple, inexpensive and compact. In normal operation, the isolation valve is not on the Emergency stop solenoid valve held in the passage position, but over the from the delivery pressure the pressure source derived pilot pressure. The emergency stop solenoid valve is energized in normal operation and in the shut-off position, so that the pilot pressure, which acts on the separation valve to the passage position, only has to overcome the force of the spring of the separating valve. The permanent one Connection of the spring chamber to the return Prevents the isolation valve unintentionally shutting off or throttling. In the event of an emergency stop, the emergency stop solenoid valve is activated de-energized and switched to its passage position, so that then Relative to the spring acting control pressure reliably the shutoff position of Disconnect valve stops and stops. The Aperture between the spring chamber and the return allows one permanent discharge of pressure medium, without the shut-off position of the separating valve to endanger. In a recent switch to normal operation can by the aperture device an optionally unwanted abrupt switching (Pressure surge) of the separating valve can be avoided.
In einer einfachen Ausführungsform kann die Blendeneinrichtung eine Düse enthalten. Da jedoch eine Düse bei hohem Druck mehr Druckmittel abströmen lässt als bei niedrigerem Druck, wäre kein gleichbleibendes Umschaltverhalten des Trennventils sichergestellt. Deshalb ist bei einer zweckmäßigen Ausführungsform die Blendenein richtung ein Zweiwege-Stromregler, der druckunabhängig eine vorbestimmte Druckmittelrate einstellt und somit ein gleichförmiges Umschaltverhalten gewährleistet. Der Zweiwege-Stromregler verbessert auch die Betriebssicherheit, weil die vorbestimmte Druckmittelrate exakt auf die Betriebsbedingungen in der hydraulischen Steuervorrichtung abgestimmt sein kann. Dabei ist es zweckmäßig, wenn der Zweiwege-Stromregler hinsichtlich der Druckmittelrate einstellbar ist.In a simple embodiment For example, the diaphragm device may include a nozzle. However, as one Nozzle at high pressure releases more pressure medium than at lower pressure, would not be consistent Switching behavior of the isolation valve ensured. That's why an expedient embodiment the Blendenein direction a two-way flow regulator, the pressure independent a predetermined Adjusting pressure medium rate and thus ensures a uniform switching behavior. The two-way current regulator also improves operational safety, because the predetermined pressure medium rate exactly on the operating conditions can be tuned in the hydraulic control device. there it is useful if the two-way current regulator with regard to the pressure medium rate is adjustable.
Bei einer zweckmäßigen Ausführungsform wird die Druckmittelrate auf ca. 0,3 bis 0,5 l/min eingestellt.at an expedient embodiment the pressure medium rate set to about 0.3 to 0.5 l / min.
Bei einer weiteren zweckmäßigen Ausführungsform wird aus Kostengründen als Zweiwege-Stromregler ein handelsübliches, in verschiedenen Spezifikationen erhältliches Senkbremsventil, vorzugsweise sogar ein Einschraub-Senkbremsventil, verwendet.In a further expedient embodiment, for cost reasons as a two-way flow regulator, a commercial, available in various specifications lowering brake valve, preferably even a screw-Senkbremsventil used.
Das Senkbremsventil kann einen zulaufseitig gegen die Kraft einer Feder verschiebbaren Blendenkolben mit wenigstens einer kleineren Zulaufblende und wenigstens einer größeren Ablaufblende enthalten. Mit der Ablaufblende wirkt eine stationäre Steuerkante derart zusammen, dass der Abströmquerschnitt aus der Ablaufblende mit steigendem Zulaufdruck stufenlos verringert wird. Auf diese Weise wird druckunabhängig stets die gleiche Druckmittelrate eingestellt.The Counterbalance valve can be an inlet side against the force of a spring slidable orifice piston with at least one smaller inlet orifice and at least one larger drainpipe contain. With the drain aperture acts a stationary control edge together so that the outflow cross section from the drain aperture with increasing inlet pressure continuously reduced becomes. In this way, the same pressure medium rate is always set pressure-independent.
Das Not-Aus-Abschaltsystem wird zweckmäßig dann verwendet, wenn die Druckquelle eine aus dem Lastdruck-Steuerkreis geregelte Regelpumpe ist. In einer Not-Aus-Situation kann der Regeldruck für die Regelpumpe entweder gehalten oder auf beliebige Weise zum Rücklauf entlastet werden.The Emergency stop shutdown system is used appropriately when the Pressure source a regulated from the load pressure control circuit control pump is. In an emergency stop situation can the control pressure for the control pump either held or relieved in any way to the return become.
Alternativ könnte die Druckquelle jedoch auch eine Konstantpumpe sein, beispielsweise eine Konstantpumpe, die mit einem drucklosen Umlaufsystem kooperiert oder gegebenenfalls bei Not-Aus abgeschaltet wird.alternative could however, the pressure source also be a constant displacement pump, for example a fixed displacement pump, which cooperates with a non-pressurized circulation system or if necessary switched off in emergency stop.
Um Schwingungen im System möglichst schnell abzudämpfen oder am Entstehen zu verhindern, ist es zweckmäßig, zwischen dem Lastdruck-Steuerkreis und dem Regelanschluss der Druckquelle eine hydraulische Dämpfvorrichtung vorzusehen.Around Vibrations in the system as fast as possible dampen or to prevent it from arising, it is expedient to switch between the load pressure control circuit and the control port of the pressure source, a hydraulic damping device provided.
Schließlich wird zweckmäßig das gesamte Not-Aus-Abschaltsystem mit der Blendeneinrichtung in ein Eingangs-Sektions-Gehäuse eingegliedert, zweckmäßigerweise in ein Eingangs-Sektions-Gehäuse z.B. für eine Regelpumpe.Finally will appropriate that entire emergency stop system with the aperture device in a Input section-housing incorporated, expediently in an input-section housing e.g. For a control pump.
