Description

Die Erfindung betrifft eine Vorrichtung zur Förderung von breiigen Massen, insbesondere Beton, bestehend aus einer zweizylindrigen Pumpe in parallel gerichteter Anordnung, wobei jeder Zylinder einen Kolben aufweist, der zum anderen Kolben gegenläufig antreibbar ist, hierbei die Zylinder aus einem etwa trichterförmig abschließenden Aufgabebehälter die Massen wechselweise über einen Rohrverteiler einer Druckleitung zuführen und der Boden des trichterförmigen Bereichs des Aufgabebehälters durch eine mit zwei senkrechten Öffnungen versehene ebene Steuerplatte gebildet ist, deren Öffnungen mit den Zylindern der Pumpe in Verbindung stehen und durch das senkrecht aufstehende Verteilerrohr wechselweise an die Druckleitung anschließbar sind, wobei das Verteilerrohr schwenkbar gelagert, stufenförmig mit achsparallel ausgerichteten Endabschnitten ausgebildet und mit einer Welle koaxial zu seiner Austrittsöffnung verbunden ist, wobei die Achsen der Welle und der Austrittsöffnung des Verteilerrohres zu den Achsen der Öffnungen in der Steuerplatte achsparallel - hierbei ein Dreieck mit zwei gleichen Schenkeln bildend - ausgerichtet sind, und wobei die Austrittsöffnung, d. h. das zur Druckleitung führende Ende des Verteilerrohres, mittels einer Kupplung schwenkbar ist.The invention relates to a device for conveying pulpy masses, in particular concrete, consisting of a two-cylinder pump in a parallel arrangement, each cylinder having a piston which can be driven in opposite directions to the other piston, in this case the cylinders from an approximately funnel-shaped feed container, the masses alternately via a pipe distributor to a pressure line and the bottom of the funnel-shaped area of the feed container is formed by a flat control plate provided with two vertical openings, the openings of which are connected to the cylinders of the pump and can be connected alternately to the pressure line through the vertically standing distributor pipe, wherein the distributor pipe is pivotally mounted, is stepped with axially parallel end sections and is connected to a shaft coaxially to its outlet opening, the axes of the shaft and the outlet opening of the distributor pipes s are aligned axially parallel to the axes of the openings in the control plate - in this case forming a triangle with two identical legs - and the outlet opening, ie. H. the end of the distributor pipe leading to the pressure line can be pivoted by means of a coupling.

Eine solche Vorrichtung wird durch die DE-PS 21 04 191 ausgewiesen, wobei nach der Zeichnung, Figur 1 bis 4, die Welle im Inneren des Behälters durch die Steuerplatte führt und nach Anspruch 1 in axialer Richtung über eine Mutter verstellbar ist..Such a device is identified by DE-PS 21 04 191, according to the drawing, Figures 1 to 4, the shaft inside the container through the control plate and is adjustable according to claim 1 in the axial direction via a nut ..

Die nach dieser Schrift zu lösende Aufgabe beinhaltet die Forderung, den Verteiler derart auszubilden und anzuordnen, daß etwa auftretender Verschleiß mit vergleichsweise geringem Aufwand von außen her ausgleichbar ist, um einen hohen Dichtigkeitsgrad zwischen den betonführenden Öffnungen der abgrenzenden Platte des Aufgabebehälters'und dem S-förmigen Verteilerrohr einstellen zu können. (S-Form = Stufenbogen).The problem to be solved according to this document includes the requirement to design and arrange the distributor in such a way that any wear that can occur can be compensated from the outside with comparatively little effort in order to achieve a high degree of tightness between the concrete-guiding openings of the delimiting plate of the feed container and the S- shaped manifold to adjust. (S-shape = step arch).

Die ausgewiesene Konzeption der Durchführung der Schwenkwelle durch die den Behälter nach unten abgrenzende ebene Steuerplatte befriedigt jedoch nicht.However, the designated design of the implementation of the swivel shaft by the flat control plate delimiting the container downwards does not satisfy.

Zum einen bedarf es einer sehr aufwendigen abdichtenden Lagerung bei der Durchführung, die im Hinblick auf das Fördermedium Beton nicht ausreichend haltbar gestaltet werden kann, da die mit dem Zementleim in die Dichtung eindringenden feinkörnigen Zuschlagstoffe äußerst abrasiv sind, so daß die Dichtigkeit der Lagerung bereits nach kurzer Zeit nicht mehr gegeben ist und zum anderen der damit verbundene Verlust, insbesondere an Zementleim, den Beton ausmagert sowie zu einer ständigen Quelle der Verunreinigung der Baustelle wird.On the one hand, a very complex sealing storage is required during the implementation, which cannot be made sufficiently durable with regard to the conveying medium concrete, since the fine-grained aggregates penetrating into the seal with the cement paste are extremely abrasive, so that the tightness of the storage already after is no longer available for a short time and on the other hand the associated loss, especially of cement paste, emaciates the concrete and becomes a constant source of contamination of the construction site.

Eine Weiterbildung sieht vor, daß die Öffnungen in der Steuerplatte mit je einem lösbar verbundenen Verschleißring versehen sind.A further development provides that the openings in the control plate are each provided with a detachably connected wear ring.

Des weiteren ist durch die DE-B-2 355 528, Figur 1, eine Pumpe bekannt, bei der, wie in allen Ausführungsformen dieser Schrift, die Lagerung außerhalb des Aufgabebehälters angeordnet ist, wobei davon ausgegangen wird, daß das Schwenkrohr oberhalb des Vorratsbehälters an einem mit dem Pumpengestell verbundenen Bockrahmen gelagert ist.Furthermore, from DE-B-2 355 528, Figure 1, a pump is known, in which, as in all embodiments of this document, the storage is arranged outside the feed container, it being assumed that the swivel tube is above the storage container a trestle frame connected to the pump frame is mounted.

Hieraus ist zu erkennen, daß die Problemstellung zwar bekannt ist, daß aber umgekehrt durch diese Ausbildung nicht die 'durch den Anmeldegegenstand vorgeschlagene einfache und wesentlich verschleißärmere Lösung nahegelegt wird.From this it can be seen that the problem is known, but that this training does not suggest the simple and much less wear-and-tear solution proposed by the subject of the application.

Durch die DE-OS 30 03 247 wird eine einheitliche Abdeckung des Verschleißmaterials über den gesamten Schwenkbereich des Verteilerrohres ausgewiesen.DE-OS 30 03 247 provides uniform coverage of the wear material over the entire swivel range of the distributor pipe.

Die Durchführung der Schwenkwelle weist gegenüber der zuvor genannten Druckschrift keine Verbesserung aus.The implementation of the swivel shaft shows no improvement over the previously mentioned document.

Dies berücksichtigend ist es Aufgabe dieser Erfindung, eine Vorrichtung nach der eingangs beschriebenen Art zu nennen, bei der die Schwenkwelle so ausgebildet und angeordnet ist, daß ein durch das zu fördernde Medium bedingter Verschleiß dieser Welle sowie eine Baustellenverschmutzung durch austretende Feinstoffe, z. B. Zementleim, nicht gegeben ist.Taking this into account, it is the object of this invention to name a device of the type described in the introduction, in which the pivot shaft is designed and arranged in such a way that wear of this shaft caused by the medium to be conveyed, as well as contamination of the construction site by escaping fines, e.g. B. cement paste is not given.

Die erfindungsgemäße Lösung dieser Aufgabe sieht vor, daß die Schwenkwelle außerhalb auf einer Seite des Aufgabebehälters gelagert ist, und daß die Lagerung der Schwenkwelle durch an der ihr zugerichteten Wandung des Aufgabebehälters angeordnete Lager oder an einer dem Aufgabebehälterfest zugeordneten Tragkonstruktion erfolgt.The solution to this problem according to the invention provides that the pivot shaft is mounted outside on one side of the feed container, and that the pivot shaft is supported by bearings arranged on the wall of the feed container facing it or on a supporting structure permanently assigned to the feed container.

Durch diese Anordnung wird in Verbindung mit der Aussage des Gattungsbegriffes der koaxialen Ausrichtung der Öffnungen in der Steuerplatte und des Eintrittsabschnittes des Verteilerrohres und der koaxialen Ausrichtung des Austrittsabschnittes des Verteilerrohres mit der Schwenkwelle bei achsparalleler Ausrichtung des Schwenkteiles des Schwenkrohres und der Schwenkwelle erreicht.This arrangement, in conjunction with the statement of the generic term, of the coaxial alignment of the openings in the control plate and the inlet section of the distributor pipe and the coaxial alignment of the outlet section of the distributor pipe with the swivel shaft with axially parallel alignment of the swivel part of the swivel pipe and the swivel shaft.

Damit ist eine sichere Fixierung der Schwenkwelle und des Verteilerrohres zur Steuerplatte gegeben.This ensures a secure fixation of the swivel shaft and the distributor pipe to the control plate.

Im Interesse eines unabhängigen Austausches, insbesondere bei nicht mehr nachstellbarem Verschleiß des zur Steuerplatte gerichteten Endes des Verteilerrohres, ist vorgesehen, daß eine lösbare Verbindung zwischen Verteilerrohr und der Schwenkwelle besteht.In the interest of an independent exchange, especially when the end of the distributor pipe facing the control plate is no longer adjustable, it is provided that there is a detachable connection between the distributor pipe and the pivot shaft.

Eine besondere Ausführungsform der Verbindung zwischen dem stufenförmig ausgebildeten Verteilerrohr und der Schwenkwelle sieht vor, daß die Stufe des Verteilerrohres in einem beliebigen Winkel zwischen dessen achsparallelen Endabschnitten verläuft und die koaxiale Verbindung der Schwenkwelle mit der Austrittsöffnung des Verteilerrohres durch eine an der Stufe angeordnete, etwa gleich zu deren Winkel gerichteten Flanschverbindung erfolgt.A special embodiment of the connection between the stepped distributor pipe and the pivot shaft provides that the step of the distributor pipe runs at any angle between its axially parallel end sections and the coaxial connection of the pivot shaft with the outlet opening tion of the distributor pipe by means of a flange connection arranged on the step and oriented approximately at the same angle.

Desweiteren kann es fallweise zweckmäßig sein, daß mit dem Verteilerrohr eine Zwischenwelle verbunden ist, der eine Hälfte der lösbaren Verbindung zugeordnet ist. Durch die mit dem Verteilerrohr verbundene Zwischenwelle läßt sich die Zugänglichkeit der Verbindungsstelle wesentlich verbessern, so daß die Montage und Demontage schnell durchgeführt werden kann.Furthermore, it may be appropriate in some cases that an intermediate shaft is connected to the distributor pipe, which half is assigned to the detachable connection. Due to the intermediate shaft connected to the distributor pipe, the accessibility of the connection point can be significantly improved, so that assembly and disassembly can be carried out quickly.

Es ist vorgesehen, daß die lösbare Verbindung eine Klauen- oder Flanschverbindung oder eine Hülsenverbindung ist, wobei deren Paßfedernut oder Vielkeilwellen-Innenverzahnung oder dgl. über die korrespondierend ausgebildete Schwenkwelle führbar ausgebildet ist.It is provided that the releasable connection is a claw or flange connection or a sleeve connection, the parallel key groove or multi-spline internal toothing or the like being designed to be able to be guided via the correspondingly designed pivot shaft.

Die Verwendung einer Hülsenverbindung erlaubt eine relativ leichte koaxiale Verschiebung und Einstellung des Verschiebemaßes zwischen Schwenkwelle und Zwischenwelle.The use of a sleeve connection allows a relatively easy coaxial displacement and adjustment of the displacement between the swivel shaft and the intermediate shaft.

Um eine quasi kontinuierliche durch Vorspannung bedingte Anpassung des Schwenkrohres entsprechend dem fortschreitenden Verschleiß an die Steuerplatte zu erreichen, ist vorgesehen, daß die lösbare Verbindung zwischen dem Verteilerrohr bzw. der ihm verbundenen Zwischenwelle oder die schwenkbare Kupplung zwischen Verteilerrohr und der Förderleitung mit einer in Richtung zur Steuerplatte weisenden Federvorspannungseinrichtung ausgerüstet ist.In order to achieve a quasi-continuous adjustment of the swivel tube due to the preload in accordance with the progressive wear on the control plate, it is provided that the detachable connection between the distributor pipe or the intermediate shaft connected to it or the swivel coupling between the distributor pipe and the delivery line with a in the direction of Control plate pointing spring biasing device is equipped.

Sowohl die angesprochene Hülsenverbindung zwischen Zwischenwelle und Schwenkwelle als auch die axiale verschieb- und schwenkbare Kupplung zwischen Verteilerrohr und Förderleitung lassen eine einfache Installation einer solchen Federvorspannungseinrichtung zu.Both the mentioned sleeve connection between the intermediate shaft and the pivot shaft as well as the axially displaceable and pivotable coupling between the distributor pipe and the delivery line allow such a spring preloading device to be installed easily.

Dadurch wird über lange Zeit eine gleichbleibende sichere Abdichtung zwischen dem zur Steuerplatte gerichteten Ende des schwenkbaren Förderrohres und den in der Steuerplatte vorgesehenen Öffnungen erreicht.As a result, a constant, secure seal is achieved for a long time between the end of the pivotable conveying tube directed towards the control plate and the openings provided in the control plate.

Die Federvorspannungseinrichtung kann sowohl die Anordnung von Spiralfedern, Tellerfedern als auch die von Gummifedern beinhalten. Ebenso ist die Anwendung pneumatischer Federn durchaus denkbar.The spring preloading device can include both the arrangement of coil springs, disc springs and that of rubber springs. The use of pneumatic springs is also conceivable.

Unabhängig davon kann es zweckmäßig sein, daß in dem eintrittsseitigen Endabschnitt des Verteilerrohres ein axial verschiebbarer Verschieißring federnd angeordnet ist.Regardless of this, it can be expedient for an axially displaceable wear ring to be arranged resiliently in the inlet-side end section of the distributor pipe.

Eine solche Ausbildung erlaubt die bereits beschriebene Festverbindung des Verteilerrohres mit der Schwenkwelle über die an der Stufe vorgesehene Flanschverbindung, die in aller Regel als Schrägflanschverbindung bezeichnet werden kann. Der Verschleißring wird dabei durch zwei Tellerfedern abgestützt.Such a design allows the already described fixed connection of the distributor pipe to the pivot shaft via the flange connection provided on the step, which can generally be referred to as an oblique flange connection. The wear ring is supported by two disc springs.

Zusammengefaßt ist zu bemerken, daß die vorgeschlagene Weiterbildung nicht nur die Lösung der eingangs gestellten Aufgabe beinhaltet, sondern darüberhinaus auf einfache Weise eine sichere Abdichtung zwischen Schwenkrohr und Steuerplatte bewirkt.In summary, it should be noted that the proposed further development not only includes the solution of the problem set out above, but also, in a simple manner, brings about a secure seal between the swivel tube and the control plate.

Der Aufgabebehälter 1 verjüngt sich nach unten etwa trichterförmig und ist durch eine als Boden wirksame Steuerplatte 2 abgeschlossen, die ihrerseits zwei zu den Zylindern 2' und 2" führende Öffnungen 3' und 3" aufweist.The feed container 1 tapers downward approximately in the shape of a funnel and is closed off by a control plate 2 which acts as a bottom and which in turn has two openings 3 'and 3 "leading to the cylinders 2' and 2".

Zu den Öffnungen 3' und 3" ist das stufenförmig ausgebildete Verteilerrohr 3 wechselweise mit . seinem zur Steuerplatte 2 gerichteten Ende verschwenkbar angeordnet, während das zur Förderleitung 5 bis 7 weisende Ende in einer Kupplung 4 verschwenkbar und in axialer Richtung verschiebbar gelagert ist.To the openings 3 'and 3 ", the stepped distributor pipe 3 is arranged alternately with its end facing the control plate 2, while the end facing the delivery line 5 to 7 is pivotable in a coupling 4 and is displaceable in the axial direction.

Das Oberteil der Kupplung 4 ist dabei an dem Umlenkknie 5 fixiert ; das Umlenkknie 5 führt über den Förderrohranschluß 6 in das Förderrohr 7, wobei eines der Teile 5/6 mit dem Aufgabebehälter direkt oder indirekt - z.
