Description

Die Erfindung betrifft einen Materialaufgabebehälter für Zweizylinder-Dickstoffpumpen der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The invention relates to a material feed container for two-cylinder high-solids pumps of the type specified in the preamble of claim 1.

Es sind Dickstoffpumpen dieser Art bekannt (EP-B 0 410 972 und DE 28 14 845), die eine nach oben weisende Materialzuführöffnung, zwei an einer Behälter-Stirnwand angeordnete, vorzugsweise mit einer Verschleißbrille versehene Förderzytinderöffnungen und eine im Behälterinneren angeordnete, eingangsseitig abwechselnd vor die Förderzylinderöffnungen verschwenkbare und ausgangsseitig in einer oberhalb der Förderzylinderöffnungen angeordneten Durchführungsöffnung der Behälterrückwand gelagerte und dort in ein von außen an die Behälterrückwand angeschlossenes Druckrohr mündende, die Gestalt eines S-Rohrs aufweisende Rohrweiche aufweisen. Die Reinigung und Wartung derartiger Behälter erfolgt üblicherweise von oben her durch die Materialzuführungsöffnung hindurch. Da im Behälterinneren zusätzlich ein Rührwerk angeordnet ist, ist der Aus- und Einbau der Rohrweiche über die Materialzuführungsöffnung mit Schwierigkeiten verbunden. Um diesen Nachteil zu vermeiden, wurde bereits vorgeschlagen, am Materialaufgabebehälter eine durch einen Verschlußdeckel verschließbare Wartungsöffnung vorzusehen, durch die hindurch das S-Rohr zugänglich ist. Die Wartungsöffnung ist dort in einer an die Stirnwand angrenzenden Seitenwand angeordnet. Dabei ist der Verschlußdeckel als mit einem Rückwerk bestücktes Seitenwandteil ausgebildet, so daß das Rückwerk beim Öffnen des Verschlußdeckels durch die betreffende Wartungsöffnung hindurch aus dem Behälterinneren herausbewegbar ist. Weiter ist es zu diesem Zweck bereits an sich bekannt (DE-A 197 31 335), ein in ihrer Gesamtheit abnehmbare Rückwand vorzusehen. Bei dieser Konstruktion leidet jedoch die Stabilität des Materialaufgabebehälters. Hinzu kommt, daß sich in der Nähe der abnehmbaren Rückwand unterhalb des S-Rohrs ein Totraum bildet, in dem sich Beton ansammeln kann, der über zusätzliche konstruktive Maßnahmen aus diesem Totraum herausbewegt werden muß.There are thick matter pumps of this type known (EP-B 0 410 972 and DE 28 14 845), which arranged an upwardly facing material feed, two arranged on a container end wall, preferably provided with wear glasses Förderzytinderöffnungen and arranged inside the container, on the input side alternately the delivery cylinder openings have pivotable and output side in a arranged above the conveying cylinder openings passage opening of the container rear wall and there opening into a connected from the outside to the container rear pressure tube opening, having the shape of an S-tube diverter. The cleaning and maintenance of such containers is usually carried out from above through the material feed opening. Since an agitator is additionally arranged in the container interior, the removal and installation of the pipe switch over the material supply opening is associated with difficulties. In order to avoid this disadvantage, it has already been proposed to provide on the material supply container a closable by a closure cover maintenance opening through which the S-tube is accessible. The maintenance opening is arranged there in a side wall adjacent to the end wall. In this case, the closure lid is designed as equipped with a return side wall part, so that the return when opening the cap through the relevant maintenance opening is moved out of the container interior. Next, it is already known for this purpose (DE-A 197 31 335) to provide a removable in its entirety rear wall. In this construction, however, the stability of the material feed container suffers. In addition, close to the removable rear wall forms a dead space below the S-tube, in which concrete can accumulate, which must be moved out of this dead space on additional design measures.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, die bekannten Materialaufgabebehälter der eingangs angegebenen Art dahingehend zu verbessern, daß eine einfache Wartung des Materialaufgabebehälters möglich und dennoch eine stabile Bauweise gewährleistet ist und Toträume im Behälterinneren vermieden werden.Proceeding from this, the present invention seeks to improve the known material feed container of the type specified in that simple maintenance of the material feed container possible and yet a stable design is guaranteed and dead spaces inside the container can be avoided.

Zur Lösung dieser Aufgabe werden die im Patentanspruch 1 angegebenen Merkmale vorgeschlagen. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To solve this problem the features specified in claim 1 are proposed. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

Die erfindungsgemäße Lösung macht von dem Gedanken Gebrauch, daß die Wartungsöffnung durch einen mit einem umlaufenden Rand begrenzten Ausschnitt in der Rückwand gebildet ist und daß der Verschlußdeckel eine die Durchführungsöffnung für das S-Rohr aufweisende, senkrecht zur Schwenkachse des S-Rohrs ausgerichtete obere Deckelpartie und eine an diese im wesentlichen parallel zu einem schräg verlaufenden S-Rohrabschnitt nach unten anschließende, einen schrägen Bodenteil bildende untere Deckelpartie aufweist. Die Wartungsöffnung muß dabei groß genug sein, damit das S-Rohr hindurch paßt. Obwohl daher die Wartungsöffnung relativ groß ist, sorgt der umlaufende Rand für eine ausreichende Formstabilität. Eine weitere Verbesserung in dieser Hinsicht ergibt sich dadurch, daß der Verschlußdeckel aus zwei schräg zueinander ausgerichteten Deckelpartien bestehen. Die untere, schräg ausgerichtete Deckelpartie verläuft in geringem Abstand zum schrägen S-Rohrabschnitt, so daß das Entstehen von Toträumen, in denen sich Beton ablagern kann, weitgehend vermieden werden.The solution according to the invention makes use of the idea that the maintenance opening is formed by a limited edge with a peripheral cutout in the rear wall and that the closure lid having a passage opening for the S-tube, aligned perpendicular to the pivot axis of the S-tube upper lid portion and Having a substantially parallel to an obliquely extending S-tube section down to this, having a sloping bottom part forming lower lid section. The maintenance opening must be large enough so that the S-tube fits through. Therefore, although the maintenance opening is relatively large, the peripheral edge provides sufficient dimensional stability. A further improvement in this regard results from the fact that the closure lid consist of two obliquely aligned lid portions. The lower, obliquely oriented lid section runs at a small distance from the oblique S-tube section, so that the emergence of dead spaces in which concrete can be deposited, are largely avoided.

Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, daß der umlaufende Rand der Wartungsöffnung eine obere Flanschpartie zum Anflanschen der oberen Deckelpartie aufweist, die eine senkrecht zur Schwenkachse ausgerichtete Ebene aufspannt, und an die sich nach unten hin eine untere Flanschpartie zum Anflanschen der unteren Deckelpartie anschließt, die eine im wesentlichen parallel zum schräg verlaufenden S-Rohrabschnitt ausgerichtete Ebene aufspannt.An advantageous embodiment of the invention provides that the peripheral edge of the maintenance opening has an upper flange for flanging the upper lid section, which spans a plane perpendicular to the pivot axis aligned plane, and at the bottom adjoins a lower Flanschpartie for flanging the lower lid section, which spans a plane oriented substantially parallel to the oblique S-tube section.

Vorteilhafterweise sind auf der Außenseite der oberen Deckelpartie seitlich neben der Durchtrittsöffnung Elemente zur lösbaren Befestigung des Förderrohrs angeordnet. Dazu gehört ein Schwenklager, an dem das Förderrohr gegenüber der Durchführungsöffnung um eine vertikale Achse verschwenkbar ist, sowie eine Schraubbohrung oder ein Befestigungsbolzen zur Fixierung des vor die Durchtrittsöffnung geschwenkten Förderrohrs.Advantageously, elements for releasably attaching the conveyor tube are arranged laterally next to the passage opening on the outside of the upper lid section. These include a pivot bearing on which the delivery pipe is pivotable about a vertical axis relative to the passage opening, and a screw hole or a fastening bolt for fixing the conveyor pipe pivoted in front of the passage opening.
