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 GB 467,288 bekannt. Diese Rotorschlauchpumpe hat für die Enden des Pumpschlauchs eine Halteeinrichtung, die in einer Kulissenführung verlagert werden kann.Such a rotor hose pump is from the GB 467,288 known. This rotor hose pump has a holding device for the ends of the pump hose, which can be displaced in a slotted guide.

Die DE 1 155 341 A offenbart eine Rotorschlauchpumpe, bei der die Enden des Pumpschlauchs mit einer Halteeinrichtung in Form von Manschetten an einem ersten und zweiten Halteblock festgelegt sind. Diese Rotorschlauchpumpe eignet sich für das Pumpen mit Pumpschläuchen, die einen unterschiedlichen Innendurchmesser haben.The DE 1 155 341 A discloses a rotor tube pump in which the ends of the pumptube are secured to a retainer in the form of cuffs on first and second support blocks. This rotor hose pump is suitable for pumping with pump hoses that have a different inner diameter.

Aus der AT 381 990 B ist eine Rotorschlauchpumpe mit einem Rotor und einer daran aufgenommenen verschiebbaren Quetschwalze bekannt, die einen in einer Schlauchführung angeordneten Pumpschlauch zusammendrückt.From the AT 381 990 B For example, there is known a rotor tube pump having a rotor and a slidable nip roll received thereon which compresses a pumptube disposed in a tube guide.

In der DE 42 04 330 A1 ist ein Fahrmischer beschrieben, der eine Rotorschlauchpumpe für Dickstoffe, wie z.B. Beton, Estrich oder Schlamm enthält. Die Rotorschlauchpumpe hat ein flachzylindrisches Pumpengehäuse mit einem Pumpschlauch, der in dem Fahrmischer über einen ersten Anschluss in Form eines Saugeingangs an einen Aufgabebehälter angeschlossen ist. Der Pumpschlauch hat einen zweiten Anschluss, der als Druckauslass wirkt und der mit einer Förderleitung verbunden ist. Die Rotorschlauchpumpe enthält einen Rotor, der den Pumpschlauch mittels zweier diametral gegenüberliegender Gummirollen gegen eine Mantelfläche des Pumpengehäuses von innen her andrückt.In the DE 42 04 330 A1 is a truck mixer described which includes a rotor hose pump for thick materials, such as concrete, screed or mud. The rotor hose pump has a flat-cylindrical pump housing with a pump hose, which is connected in the truck mixer via a first connection in the form of a suction inlet to a feed container. The pump tubing has a second port which acts as a pressure outlet and which is connected to a delivery line. The rotor hose pump includes a rotor, which presses the pump hose by means of two diametrically opposed rubber rollers against a lateral surface of the pump housing from the inside.

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.

Die Mischtrommel 16 hat eine Beschickungs- und Auslassöffnung 14, die auf dem Fahrgestell 10 schräg nach hinten oben weist. In der Nähe des rückwärtigen Endes ist hinter den Hinterachsen 18, 18' an dem Fahrgestell 10 eine Rotorschlauchpumpe 20 angeordnet. Die Rotorschlauchpumpe 20 hat ein Pumpengehäuse 42 mit einem Pumpschlauch, der mit einem Materialaufgabebehälter 36 verbunden ist. Der Fahrmischer enthält einen Verteilermast 30 mit einer Förderleitung 31.

Die Rotorschlauchpumpe 20 weist einen zweiten Anschluss 37 an einem Leitungsstück 38 mit einem Kupplungsteil 40 auf, das für den Anschluss einer Druckförderleitung dient. Durch die bei drehendem Rotor 48 in Pfeilrichtung 55 umlaufenden und den Pumpschlauch zusammendrückenden Gummirollen 50, 52 wird der Beton aus dem Materialaufgabebehälter 36 über den Anschluss 32 angesaugt und durch en Pumpschlauch 46 hin zum Anschluss 37 in die Druckförderleitung 31 am Mast gedrückt. Beim Rückwärtspumpen, z. B. zur Reinigung, wird der Rotor 48 in Pfeilrichtung 54 betätigt. Der Beton wird in Richtung Materialaufgabebehälter 36 zurückgepumpt.Like from the Fig. 2 and the Fig. 3 As can be seen, the rotor hose pump 20 has a first port 32 on a pipe section 34 which is connected to a material feed tank 36. The rotor hose pump 20 has a second connection 37 on a line piece 38 with a coupling part 40, which serves for the connection of a pressure feed line.

The first holding device 61 is attached to the line piece 34 on the material supply container 36. The first holding device 61 is received on the base 72 with an adjusting device 76 via the material feed container 36. Via the adjusting device 76, the first holding device 61 can be displaced together with the material feed container 36 with a linear degree of freedom of movement in the direction 75. The adjusting device 76 includes a locking mechanism 94.

Die Fig. 4 ist ein Teilschnitt der Rotorschlauchpumpe 20. Der Sperrmechanismus 94 enthält eine Zahnstange 96. Die Zahnstange 96 ist an der Basis 72 der Rotorschlauchpumpe 20 mit einer Schraube 115 festgelegt. Der Sperrmechanismus 94 unterbindet eine Bewegung der ersten Halteeinrichtung 61 in der zu dem Pumpengehäuse 42 weisenden Richtung 99. Eine Bewegung der Halteeinrichtung 61 in der zu dem Anschluss 32 weisenden entgegengesetzten Richtung 103 wird mit dem Sperrmechanismus 94 dagegen freigegeben. In der Basis 72 gibt es ein Langloch 93, in dem der Materialaufgabebehälter 38 linear gleitend mittels Bolzen 95 geführt wird.The Fig. 4 is a partial section of the rotor tube pump 20. The locking mechanism 94 includes a rack 96. The rack 96 is fixed to the base 72 of the rotor tube pump 20 with a screw 115. The lock mechanism 94 inhibits movement of the first retainer 61 in the direction of the pump housing 42. A movement of the retainer 61 in the opposite direction 103 facing the terminal 32 is released with the lock mechanism 94. In the base 72 there is a slot 93 in which the material supply container 38 is guided linearly sliding by means of bolts 95.

Der Sperrmechanismus 94 ist in der Fig. 5 gezeigt. Die Zahnstange 96 des Sperrmechanismus 94 hat mehrere Zähne 98, die abwechselnd steile und flachen Flanken 100, 102 haben und die eine Klinkenrast 104 bilden. Der Sperrmechanismus weist eine in einem Schwenklager 106 an einer Welle 108 aufgenommene Klinke 110 mit einem Rastabschnitt 112 auf, der mit den Zähnen 98 der Zahnstange 96 zusammenwirkt. In dem Sperrmechanismus 94 gibt es eine als Blattfeder 101 ausgebildete Federeinrichtung, die an dem Haltesystem 114 festgelegt ist, welche die Klinke 110 mit einem Federmoment beaufschlagt, das den Rastabschnitt 112 der Zahnstange 96 in die Klinkenrast 104 drückt.The locking mechanism 94 is in the Fig. 5 shown. The rack 96 of the locking mechanism 94 has a plurality of teeth 98, which have alternately steep and flat flanks 100, 102 and which form a pawl latch 104. The locking mechanism has a latch 110 received in a pivot bearing 106 on a shaft 108 with a latching portion 112 which cooperates with the teeth 98 of the rack 96. In the locking mechanism 94 there is formed as a leaf spring 101 spring means which is fixed to the holding system 114 which acts on the pawl 110 with a spring torque which presses the latching portion 112 of the rack 96 in the pawl 104.

Die Fig. 4 zeigt die Verstelleinrichtung 76 der Rotorschlauchpumpe 20 mit einer Stellung des Sperrmechanismus 94, bei welcher der Rastabschnitt 112 der Klinke 110 mit der Klinkenrast 104 der Zahnstange 96 in Eingriff ist. Wie die Fig. 4 zeigt, bewirkt der Sperrmechanismus 94, dass die erste Halteeinrichtung 61 für den Pumpschlauch 46 in der Richtung 99 mit einer Zugkraft beaufschlagt werden kann, ohne dass die Halteeinrichtung 61 mit dem darin gehaltenen Abschnitt 62 des Pumpschlauchs 46 verlagert wird. Eine solche Zugkraft wirkt auf die erste Halteeinrichtung 61, wenn der Rotor 48 mit den Gummirollen 50, 52 den Pumpschlauch 46 in einer dem Fördern von Medium von dem ersten Anschluss 32 zu dem zweiten Anschluss 37 entsprechenden Förderrichtung zusammendrückt.The Fig. 4 shows the adjusting device 76 of the rotor tube pump 20 with a position of the locking mechanism 94, in which the latching portion 112 of the pawl 110 with the pawl 104 of the rack 96 is engaged. As the Fig. 4 shows, the locking mechanism 94 causes the first holding means 61 for the pumping tube 46 in the direction 99 can be subjected to a tensile force, without the holding means 61 is displaced with the portion 62 of the pumping tube 46 held therein. Such a pulling force acts on the first holding device 61 when the rotor 48 with the rubber rollers 50, 52 compresses the pumping tube 46 in a conveying direction corresponding to the conveyance of medium from the first connection 32 to the second connection 37.

Wenn dagegen auf die Halteeinrichtung 61 in einer der Richtung 99 entgegengesetzten Richtung 103 eine Schubkraft wirkt, welche die Reibungskräfte für die Halteeinrichtung in der Linearführung der Verstelleinrichtung 76 übersteigt, wird die Klinke 110 um die Welle 108 entsprechend dem Pfeil 120 geschwenkt, so dass die Zahnstange 96 freigegeben wird. Die Fig. 6 zeigt die Verstelleinrichtung 76 der Rotorschlauchpumpe 20 mit einer Stellung des Sperrmechanismus 94, bei welcher die Klinkenrast 104 der Zahnstange 96 und der Rastabschnitt 112 der Klinke 110 außer Eingriff geraten sind. Die Folge ist, dass dann die Halteeinrichtung 61 durch diese Schubkraft mit dem Leitungsstück 34 in Bezug auf die Basis 72 verlagert wird. Eine solche Schubkraft wirkt auf die erste Halteeinrichtung 61, wenn der Rotor 48 der Rotorschlauchpumpe 20 den Pumpschlauch 46 in der Richtung des Pfeils 54 zusammendrückt.If, on the other hand, a thrust force acting on the holding device 61 in a direction 99 opposite the direction 103, which exceeds the friction forces for the holding device in the linear guide of the adjusting 76, the pawl 110 is pivoted about the shaft 108 corresponding to the arrow 120, so that the rack 96 is released. The Fig. 6 shows the adjusting device 76 of the rotor tube pump 20 with a position of the locking mechanism 94, in which the pawl latch 104 of the rack 96 and the latching portion 112 of the pawl 110 are disengaged. The result is that then the holding device 61 by this thrust with the Line piece 34 is displaced with respect to the base 72. Such a pushing force acts on the first holding device 61 when the rotor 48 of the rotor tube pump 20 compresses the pumping tube 46 in the direction of the arrow 54.

In der Fig. 7 ist die Verstelleinrichtung 76 der Rotorschlauchpumpe 20 mit einer weiteren Stellung des Sperrmechanismus 94 gezeigt, bei welcher die Klinkenrast 104 der Zahnstange 96 und der Rastabschnitt 112 der Klinke 110 in Eingriff sind.In the Fig. 7 the adjusting device 76 of the rotor tube pump 20 is shown with a further position of the locking mechanism 94, in which the pawl latch 104 of the rack 96 and the latching portion 112 of the pawl 110 are engaged.

Die erfindungsgemäße Rotorschlauchpumpe 20 ist so ausgelegt, dass bei einem Betreiben des Rotors 48, bei dem der Pumpschlauch 46 in einer dem Fördern von Medium von dem zweiten Anschluss 37 zu dem ersten Anschluss 32 entsprechenden Förderrichtung zusammengedrückt wird, eine auf die erste Halteeinrichtung 61 mit dem ersten Anschlussabschnitt 62 übertragene Schubkraft, die in die Richtung 103 zu dem ersten Anschluss 32 weist, in eine Linearbewegung der Halteeinrichtung 61 in der Verstelleinrichtung 76 umgesetzt wird. Auf diese Weise lässt sich ein selbsttätiges Nachstellen des Pumpschlauchs 46 bewirken.The rotor tube pump 20 according to the invention is designed such that, when operating the rotor 48, in which the pump tubing 46 is compressed in a conveying direction corresponding to the conveyance of medium from the second port 37 to the first port 32, one on the first holding device 61 with the first connecting portion 62 transmitted thrust, which points in the direction 103 to the first terminal 32, is converted into a linear movement of the holding means 61 in the adjusting 76. In this way, an automatic readjustment of the pump tube 46 can be effected.

Es sei bemerkt, dass in einer erfindungsgemäßen Rotorschlauchpumpe alternativ oder zusätzlich zu der Verstelleinrichtung 96 eine Verstelleinrichtung für die zweite Halteeinrichtung 66 vorgesehen sein kann, mit der es möglich ist, die zweite Halteeinrichtung 66 gegenüber der ersten Halteeinrichtung 61 zu verlagern. Auch diese Verstelleinrichtung enthält einen Sperrmechanismus, der eine Bewegung der zweiten Halteeinrichtung 66 in einer an dem zweiten Anschluss 37 weisenden Richtung freisetzt und in einer dazu entgegengesetzten Richtung unterbricht.It should be noted that, alternatively or in addition to the adjusting device 96, an adjusting device for the second holding device 66 can be provided in a rotor hose pump according to the invention, with which it is possible to displace the second holding device 66 with respect to the first holding device 61. This adjusting device also contains a locking mechanism, which releases a movement of the second holding device 66 in a direction pointing to the second connection 37 and interrupts in a direction opposite thereto.

Zusammenfassend sind folgende bevorzugten Merkmale festzuhalten: Eine Rotorschlauchpumpe 20 hat einen Pumpschlauch 46, der für das Pumpen von Medium von einem ersten Anschluss 32 zu einem zweiten Anschluss 37 oder umgekehrt mit einem Rotor 48 entlang einer Förderrichtung zusammengedrückt werden kann. Die Rotorschlauchpumpe 20 enthält eine erste Halteeinrichtung 61, die den Pumpschlauch 46 in einem zu dem ersten Anschluss 32 weisenden ersten Abschnitt 62 hält. In der Rotorschlauchpumpe 20 gibt es eine zweite Halteeinrichtung 66, die den Pumpschlauch 46 in einem zu dem zweiten Anschluss 37 weisenden zweiten Abschnitt 70 aufnimmt. Die Rotorschlauchpumpe 20 weist eine die erste Halteeinrichtung 61 aufnehmende Verstelleinrichtung 76 auf, mit der die erste Halteeinrichtung 61 mit dem darin gehaltenen Abschnitt 62 des Pumpschlauchs 46 gegenüber der zweiten Halteeinrichtung 66 verlagert werden kann.In summary, the following preferred features are to be noted: A rotor hose pump 20 has a pump hose 46 which is suitable for pumping medium from a first connection 32 to a second connection 37 or conversely can be compressed with a rotor 48 along a conveying direction. The rotor tube pump 20 includes a first holding device 61, which holds the pump tube 46 in a direction to the first terminal 32 first portion 62. In the rotor tube pump 20, there is a second holding device 66 which receives the pump tube 46 in a second section 70 facing the second connection 37. The rotor hose pump 20 has an adjusting device 76 receiving the first holding device 61, with which the first holding device 61 with the section 62 of the pumping hose 46 held therein can be displaced relative to the second holding device 66.
