Description
Die Erfindung betrifft eine Rotorschlauchpumpe mit einem Pumpschlauch, der für das Pumpen von Medium von einem ersten Anschluss zu einem zweiten Anschluss oder umgekehrt mit einem Rotor entlang einer Förderrichtung zusammengedrückt werden kann, mit einer ersten Halteeinrichtung, die den Pumpschlauch in einem zu dem ersten Anschluss weisenden ersten Abschnitt hält, und mit einer zweiten Halteeinrichtung, die den Pumpschlauch in einem zu dem zweiten Anschluss weisenden zweiten Abschnitt aufnimmt, und mit einer die erste Halteeinrichtung aufnehmende Verstelleinrichtung, mit der die erste Halteeinrichtung mit dem darin gehaltenen Abschnitt des Pumpschlauchs gegenüber der zweiten Halteeinrichtung verlagert werden kann.The invention relates to a rotor hose pump having a pump hose, which can be compressed for pumping medium from a first connection to a second connection or vice versa with a rotor along a conveying direction, with a first holding device, which faces the pump tube in a direction to the first connection first section holds, and with a second holding device which receives the pump tube in a facing to the second port second portion, and having a first holding means receiving adjusting means, with which the first holding means with the held therein portion of the pump tube relative to the second holding device moves can be.
Eine derartige Rotorschlauchpumpe ist aus der

In der
Die bei Betrieb einer Rotorschlauchpumpe an dem Pumpschlauch angreifenden Kräfte ziehen den Pumpschlauch in der Förderrichtung in die Länge. Wenn diese Längung zu groß wird, besteht die Gefahr, dass der Rotor den Pumpschlauch beschädigt, weil dieser gestaucht und/oder gequetscht wird. Dies führt zu einem unerwünschten Absenken der Pumpleistung und verringert die Standzeit des Pumpschlauchs. Um einer unnötigen Verringerung der Standzeit des Pumpschlauchs in einer Rotorschlauchpumpe entgegenzuwirken, ist deshalb das regelmäßige Nachstellen des Pumpschlauchs erforderlich. Weil bei herkömmlichen Rotorschlauchpumpen dieses Nachstellen manuell erfolgen muss, ist der Betrieb solcher Rotorschlauchpumpen mit einem hohen Wartungsaufwand verbunden.The forces acting on the pump hose during operation of a rotor hose pump pull the pump hose in the conveying direction in the length. If this elongation becomes too great, there is a risk of the rotor damaging the pump tubing because it is being squashed and / or squeezed. This leads to an undesirable lowering of the pump power and reduces the service life of the pump tube. To counteract an unnecessary reduction in the service life of the pump tube in a rotor tube pump, therefore, the regular readjustment of the pump tube is required. Because this adjustment must be done manually in conventional rotor hose pumps, the operation of such rotor hose pumps is associated with a high maintenance.
Aufgabe der Erfindung ist es, eine Schlauchpumpe bereitzustellen, die auch bei einem verringerten Wartungsaufwand mit im Wesentlichen konstanter Pumpleistung zuverlässig betrieben werden kann.The object of the invention is to provide a peristaltic pump that can be operated reliably even with a reduced maintenance effort with substantially constant pumping power.
Diese Aufgabe wird durch die in Anspruch 1 angegebene Rotorschlauchpumpe gelöst.This object is achieved by the rotor hose pump specified in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Advantageous embodiments of the invention are specified in the dependent claims.
Auf diese Weise wird eine Rotorschlauchpumpe bereitgestellt, bei der die Länge des Pumpschlauchs einfach nachgestellt werden kann, indem der Rotor in einem Rückwärtsbetrieb der Förderrichtung entgegen bewegt wird.In this way, a rotor tube pump is provided, in which the length of the pump tube can be easily readjusted by the rotor being moved counter to the conveying direction in a reverse operation.
Die Verstelleinrichtung weist einen Sperrmechanismus auf, der eine Bewegung der ersten Halteeinrichtung in einer zu dem ersten Anschluss weisenden Richtung freigibt und in einer dazu entgegengesetzten Richtung unterbindet.The adjusting device has a locking mechanism, which releases a movement of the first holding device in a direction pointing to the first connection direction and prevents it in a direction opposite thereto.
Der Sperrmechanismus der Verstelleinrichtung kann eine Zahnstange mit einer Klinkenrast enthalten, die mehrere Zähne mit in die erste Richtung weisenden steilen Flanken und in die zweite Richtung weisenden flachen Flanken hat und die mit einer in einem Schwenklager aufgenommenen schwenkbeweglichen Sperrklinke zusammenwirkt, welche bei einem Verlagern der ersten Halteeinrichtung in der Verstelleinrichtung relativ zu der Zahnstange bewegt werden kann, so dass die Klinkenrast freigegeben wird, wenn die Halteeinrichtung für den Pumpschlauch in die erste Richtung bewegt wird und die Sperrklinke bei einem Verlagern der Halteeinrichtung für den Pumpschlauch in die zweite Richtung mit der Klinkenrast verrastet.The locking mechanism of the adjusting device may include a rack with a pawl detent having a plurality of teeth with steep flanks pointing in the first direction and flanks pointing in the second direction and cooperating with a pivotal pawl received in a pivot bearing which is displaced when the first one moves Holding means in the adjusting device can be moved relative to the rack, so that the latching latch is released when the holding means for the pumping tube is moved in the first direction and the pawl locked in a displacement of the holding device for the pump tube in the second direction with the pawl latch.
Indem die Sperrklinke mit der Federkraft eines Federmittels beaufschlagt wird, um die Sperrklinke gegen die Zahnstange zu drücken, lässt sich ein selbsttätiges Lösen des Sperrmechanismus unterbinden, wenn die Schlauchpumpe mit einem Fahrzeug über unebenes Baustellengelände bewegt wird.By urging the pawl with the spring force of a spring means to push the pawl against the rack, an automatic release of the locking mechanism can be prevented when the peristaltic pump is moved with a vehicle over uneven construction site terrain.
Die erfindungsgemäße Rotorschlauchpumpe kann z.B. in einen Fahrmischer integriert werden.The rotor hose pump according to the invention may e.g. be integrated into a truck mixer.
Im Folgenden wird die Erfindung anhand des in den Zeichnungen in schematischer Weise dargestellten Ausführungsbeispiels näher erläutert.In the following the invention will be explained in more detail with reference to the embodiment shown schematically in the drawings.
