Die Erfindung betrifft eine Betätigungsvorrichtung für mindestens ein hydraulisches
Ventil eines Flurförderzeugs entsprechend dem Oberbegriff des Patentanspruchs 1.The invention relates to an actuating device for at least one hydraulic
Valve of an industrial truck according to the preamble of
Hydraulische Schieberventile, beispielsweise zur Steuerung der verschiedenen Funktionen einer Lastaufnahmevorrichtung, sind bei Flurförderzeugen in der Regel im Bereich einer Fahrerkabine angeordnet, wobei eine Bewegung des Betätigungshebels mechanisch auf den Ventilschieber übertragen wird. Betätigungsvorrichtungen des Standes der Technik weisen hierzu ein aufwendiges mechanisches Gestänge auf, mit dem eine Schwenkbewegung des Betätigungshebels in eine Längsbewegung des Ventilschiebers übertragen wird.Hydraulic slide valves, for example to control the various Functions of a load suspension device are usually in the case of industrial trucks Arranged area of a driver's cabin, wherein a movement of the Actuating lever is mechanically transferred to the valve spool. Actuators of the prior art have a complex for this mechanical linkage with which a pivoting movement of the Actuating lever is transmitted in a longitudinal movement of the valve spool.
Aus der Druckschrift GB 2 278 422 A ist eine Betätigungsvorrichtung für einen
Ventilschieber bekannt, bei der der Betätigungshebel über einen Zwischenhebel
gelenkig mit dem Ventilschieber verbunden ist. Betätigungshebel und Zwischenhebel
sind an einer Batteriefachhaube bewegbar gelagert und werden bei einem Öffnen der
Batteriefachhaube gemeinsam mit dieser verschwenktFrom
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine einfach aufgebaute, einfach und unabhängig von einer Batteriefachhaube montierbare Betätigungsvorrichtung zur Verfügung zu stellen, die ergonomisch vorteilhaft betätigbar ist.The present invention has for its object to provide a simple, easy to install independently of a battery compartment hood Actuator to provide the ergonomically advantageous can be actuated.
Diese Aufgabe wird erfindungsgemäß gelöst durch die kennzeichnenden Merkmale
des Anspruchs 1.According to the invention, this object is achieved by the characterizing features
of
Der Betätigungshebel ist hierbei entweder direkt oder indirekt, über ein an dem Betätigungshebel befestigtes Verbindungsstück, an den beiden Achsen gelagert. Bezüglich der ersten Achse weist der Betätigunshebel lediglich einen rotatorischen Freiheitsgrad auf. Bezüglich der zweiten Achse besitzt der Betätigungshebel einen rotatorischen Freiheitsgrad sowie einen translatorischen Freiheitsgrad, womit eine Änderung des Abstands der ersten Achse zur zweiten Achse ausgeglichen werden kann. Eine derartige Festlegung des Betätigungshebels wird beispielsweise mittels eines Langlochs oder einer gabelförmigen Aufnahme erreicht. Mindestens ein Betätigungshebel ist von einer Betriebsposition in eine Außerbetriebsposition bewegbar. Während des Betriebs des Flurförderzeugs nehmen die Betätigungshebel ihre Betriebsposition ein, womit die Stellungen des Betätigungshebels bei Neutralstellung und bei Betätigung des Ventils umfaßt sind. Bei in Außerbetriebsposition befindlichem Betätigungshebel ist eine Betätigung des Ventils nicht vorgesehen. Die nicht an dem Ventilschieber angeordnete Achse ist an einem zwischen einer Betriebsposition und einer Außerbetriebsposition relativ zu dem Flurförderzeug bewegbaren Träger angeordnet. Die Betriebsposition bzw. Außerbetriebsposition des Trägers entspricht der entsprechenden Position des Betätigungshebels. Die an dem Träger angeordnete Achse, und damit der Betätigungshebel, werden mit dem Träger mitbewegt. Eine ergonomische Anordnung ergibt sich dadurch, dass der Betätigungshebel in Betriebsposition zumindest teilweise oberhalb einer Haube eines Batteriefachs des Flurförderzeugs angeordnet ist. Ein Fahrersitz befindet sich in der Regel auf der Haube des Batteriefachs. Der Träger oder ein starr mit dem Träger verbundenes Bauteil ist bei in Betriebsposition befindlichem Träger derart angeordnet, daß ein Öffnen der Haube verhindert ist. Die Haube ist somit bei in Betriebsstellung befindlichen Betätigungshebeln automatisch verschlossen.The operating lever is either direct or indirect, via a to the Actuator lever-attached connector, mounted on the two axles. With regard to the first axis, the actuating lever only has a rotary one Degree of freedom. With regard to the second axis, the operating lever has one rotational degree of freedom as well as a translational degree of freedom, with which a Changes in the distance of the first axis to the second axis can be compensated can. Such a determination of the operating lever is, for example, by means of an elongated hole or a fork-shaped receptacle. At least one Actuating lever is from an operating position to a non-operating position movable. The actuating levers move while the truck is operating their operating position, whereby the positions of the actuating lever Neutral position and when operating the valve are included. At in Operating lever located out of operation is an actuation of the valve not provided. The axis that is not arranged on the valve slide is on one between an operating position and a non-operating position relative to the Truck arranged movable carrier. The operating position or Out of service position of the carrier corresponds to the corresponding position of the Actuating lever. The axis arranged on the carrier, and thus the Operating levers are moved with the carrier. An ergonomic arrangement results from the fact that the operating lever at least in the operating position partially arranged above a hood of a battery compartment of the industrial truck is. A driver's seat is usually located on the hood of the battery compartment. The Carrier or a component rigidly connected to the carrier is in the operating position located carrier arranged so that opening of the hood is prevented. The The hood is thus automatic when the operating levers are in the operating position locked.
Eine der beiden Achsen ist an dem Ventilschieber oder, mit der gleichen Wirkung, an einem mit dem Ventilschieber starr verbundenen Bauteil angeordnet, wobei die Achse senkrecht zur Bewegungsrichtung des Ventilschiebers ausgerichtet ist und sich somit bei Betätigung des Ventils relativ zu dem Ventilschieber bewegt.One of the two axes is on the valve spool or on, with the same effect a component rigidly connected to the valve slide arranged, the axis is aligned perpendicular to the direction of movement of the valve spool and thus moved relative to the valve spool when the valve is actuated.
Zweckmäßigerweise weist diejenige Achse, die nicht an dem Ventilschieber angeordnet ist, während des Betriebs des Flurförderzeugs eine relativ zum Flurförderzeug nicht veränderbare Lage auf.Advantageously, the axis that is not on the valve slide is arranged during operation of the industrial truck a relative to Truck cannot change position.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist die erste Achse an dem Ventilschieber angeordnet und weist die zweite Achse während des Betriebs des Flurförderzeugs eine relativ zum Flurförderzeug nicht veränderbare Lage auf. Die Lage des Betätigungshebeis ist somit in Bezug zu dem Ventil exakt definiert.According to a preferred embodiment of the invention, the first axis is on the Valve slide arranged and has the second axis during the operation of the Industrial truck in a position that cannot be changed relative to the industrial truck. The The position of the actuating lever is thus precisely defined in relation to the valve.
Eine vorteilhafte Weiterbildung der Erfindung liegt vor, wenn die nicht an dem Ventilschieber angeordnete Achse mindestens einseitig, vorzugsweise beidseitig elastisch gelagert ist. Über die elastische Lagerung können Toleranzungenauigkeiten ausgeglichen werden und wird eine Übertragung von Schwingungen des Flurförderzeugs auf den Betätigungshebel gedämpft. An advantageous development of the invention is present when the is not on the Valve slide arranged axis at least on one side, preferably on both sides is mounted elastically. Tolerance inaccuracies can occur via the elastic mounting be balanced and will transmit vibrations of the Truck dampened onto the operating lever.
Regelmäßig sind bei Flurförderzeugen zwei oder mehrere nebeneinander angeordnete Ventile mit jeweils einem Ventilschieber vorgesehen, wobei jeder Ventilschieber mit jeweils einem Betätigungshebel verbunden ist.In industrial trucks, two or more are regularly next to each other arranged valves each provided with a valve spool, each Valve slide is connected to an operating lever.
Zweckmäßigerweise sind die Betätigungshebel an einer gemeinsamen, nicht an dem Ventilschieber angeordneten Achse gelagert, die während des Betriebs des Flurförderzeugs eine relativ zum Flurförderzeug nicht veränderbare Lage aufweist. Die Anzahl der erfordertichen Bauteile kann hierdurch gegenüber den bekannten Anordnungen des Standes der Technik erheblich reduziert werden.The actuating levers are expediently on a common, not on the Valve spool arranged axis mounted during the operation of the Industrial truck has a position that cannot be changed relative to the industrial truck. The number of required components can hereby be compared to the known Prior art arrangements can be significantly reduced.
Jeder Betätigungshebel ist weiterhin jeweils an einer an dem entsprechenden Ventilschieber angeordneten Achse gelagert. Die an den verschiedenen Ventilschiebern angeordneten Achsen können naturgemäß nicht starr miteinander verbunden werden.Each operating lever is still on the corresponding one Valve slide arranged axis mounted. The different ones Axles arranged on valve spools cannot naturally be rigid with each other get connected.
Die an den verschiedenen Ventilschiebern angeordneten Achsen sind bei Neutralstellung der Ventilschieber zueinander im wesentlichen koaxial.The axes arranged on the various valve spools are at Neutral position of the valve spool essentially coaxial with each other.
Vorzugsweise ist der Träger zwischen der Betriebsposition und der Außerbetriebsposition um eine Schwenkachse schwenkbar.The carrier is preferably between the operating position and the Decommissioned position pivotable about a pivot axis.
Mit besonderem Vorteil ist die Schwenkachse des Trägers bei Neutralstellung des Ventilschiebers im wesentlichen koaxial zu der an dem Ventilschieber angeordneten Achse. Hierdurch ist sichergestellt, daß die Ventile bei einem Schwenken des Trägers nicht unbeabsichtigt betätigt werden.The pivot axis of the carrier is particularly advantageous when the Valve spool substantially coaxial with that arranged on the valve spool Axis. This ensures that the valves when pivoting the carrier not be operated unintentionally.
Darüber hinaus ist der Träger zweckmäßigerweise in seiner Betriebsposition arretierbar. Während des Betriebs des Flurförderzeugs ist das Batteriefach sicher verschlossen. Auf eine zusätzliche Verriegelungsvorrichtung für die Haube kann verzichtet werden.In addition, the carrier is expediently in its operating position lockable. The battery compartment is secure when the truck is operating locked. On an additional locking device for the hood can to be dispensed with.
