Description

Die Erfindung betrifft eine Zuteilvorrichtung im Masseaufgabebehälter einer hydraulisch betriebenen Kolbenpumpe zur Förderung von dickflüssigen, breiigen oder plastischen Massen, z. B. Beton, mit einem im Masseaufgabebehälter schwenkbar angeordneten Zuteilrohr.The invention relates to an allocation device in the bulk feed container a hydraulically operated piston pump for pumping thick, mushy or plastic masses, e.g. B. concrete, with a pivotable in the bulk feed container arranged metering pipe.

Bei Betonpumpen bekannter Bauarten werden die Verbindungen zwischen Masseaufgabebehälter und Förderzylinder einerseits und Förderzylinder und Förderleitung andererseits durch Flach- oder Drehschieber wechselweise hergestellt. Die Betätigung dieser Schieber erfordert große Verstellkräfte, da das Fördergut - auch wenn es unter oft erheblichem Förderdruck steht - durchschnitten werden muß. Die Führung dieser Schieber und deren Abdichtung zur Vermeidung von Fördergutverlusten ist problematisch. Die Führung der Schieber liegt im Fördergut und wird von dem unter Förderdruck stehenden Fördergut verschmutzt und führt zu Verklemmungen, die oft die Förderung unterbrechen. Da die Schieberführungen ins Freie führen, wirkt sich an diesen Stellen der Verlust von dünnerem Fördergutbestandteil, beispielsweise Wasser-Zement-Gemisch, für die Förderung nachteilig aus, da diese Stoffe die Qualität des Fördergutes beeinflussen und außerdem die Gleitfähigkeit des Fördergutes herabgesetzt wird. Das in seiner Konsistenz veränderte Fördergut neigt durch diese Entmischung zur Bildung von Verstopfern.In concrete pumps of known types, the connections between Bulk feed container and delivery cylinder on the one hand and delivery cylinder and delivery line on the other hand, alternately produced by flat slide or rotary slide valve. The operation this slide requires large adjustment forces because the conveyed material - even if it is often under considerable pressure - must be cut through. The leadership this slide and its sealing to avoid losses of conveyed goods is problematic. The slide is guided in the conveyed material and is controlled by the conveying pressure The conveyed material is dirty and leads to deadlocks, which often interrupt the conveyance. Since the slide guides lead to the outside, the loss occurs at these points of thinner material to be conveyed, for example a water-cement mixture, for Funding is disadvantageous because these substances affect the quality of the material to be conveyed and also the sliding ability of the conveyed goods is reduced. That in his Due to this segregation, the consistency of the conveyed material tends to form clogs.

Die Förderkolben sind fest an den Kolbenstangen hydraulischer Arbeitszylinder montiert und werden zum Wechsel in besondere aufklappbare Montagekammern gefahren. Es sind auch Bauarten bekanntgeworden, wonach die Förderkolben mit einem basonderen den Kolben reinigenden Spülsystem versehen sind.The delivery pistons are fixed to the piston rods of hydraulic working cylinders assembled and are moved into special hinged assembly chambers to change. There are also designs known, according to which the delivery piston with a basonderen the piston cleaning rinsing system are provided.

Zur Vermeidung dieser Nachteile wurden Pumpen anderer Bauart bekannt, wonach beispielsweise die Förderzylinder zum Füllen vor die Ansaugöffnung eines Massebehälters und zum Fördern vor eine Förderleitung, jeweils wechselnd, geschwenkt werden. Für die Abdichtung dieser voreinander gleitenden Trennstellen gilt auch das Vorhergesagte.To avoid these disadvantages, pumps of other types have been known, after which, for example, the delivery cylinder for filling in front of the suction opening of a Mass container and for conveying in front of a conveying line, each alternating, pivoted will. The same applies to the sealing of these separating points, which slide in front of one another the predicted.

Die Aufgabe der Erfindung ist es, diese geschilderten Nachteile zu beseitigen und störungsfreie Förderung zu ermöglichen. Dieses wird dadurch erreicht, daß die Förderzylinderöffnungen, die in den Masseaufgabebehälter münden, in einer von der in den Massebehälter mündenden Öffnung der Förderleitung unterschiedlichen Höhe an einander gegenüberliegenden Wänden des Masseaufgabebehälters angeordnet sind und daß ein an der Öffnung der Förderleitunü beweglich befestigtes, mit den Zylinderöffnungen wechselweise die Verbindung herstellendes Zuteilrohr zu diesem Zwecke vor den Zylinderöffnungen radial verschwenkbar ist.The object of the invention is to address these disadvantages eliminate and enable trouble-free delivery. This is achieved by that the feed cylinder openings that open into the bulk feed container in a different from the opening of the delivery line opening into the mass container Height arranged on opposite walls of the mass feed container are and that a movably attached to the opening of the Förderleitunü, with the Cylinder openings alternately connecting the metering pipe to this Purposes in front of the cylinder openings is radially pivotable.

An den Verbindungsstellen etwa austretende flüssige Bestandteile des Fördergutes können nicht ins Freie gelangen, sondern verbleiben im Masseaufgabebehälter und werden durch an dem Zuteilrohr angeordnete Rührwerkzeuge dem Fördergut wieder beigemischt.Any liquid components of the leaking out at the connection points Conveyed goods cannot get outside, but remain in the bulk feed container and are returned to the conveyed material by means of agitating tools arranged on the metering pipe mixed in.

Auch auf dem Boden des Masseaufgabebehälters sich absetzende grobere Bestandteile des Fördergutes werden durch ein unter dem radial verschwenkbaren Zuteilrohr angeordnete, den Boden bestreichende Räumwerkzeuge wieder dem Fördergut zugemischt.Coarse deposits also settle on the bottom of the bulk feed container Components of the material to be conveyed are conveyed through a metering pipe that can be swiveled radially under the feed pipe arranged, sweeping the ground clearing tools mixed back into the conveyed material.

Die im Innern des Masseaufgabebehälters voreinander gleitenden Flächen sind gepanzert und im Boden des Masseaufgabebehälters sind Reinigungsöffnungen und Öffnungen für die Einleitung flüssiger Medien zur Konsistenzänderung des Fördergutes angeordnet. Die Förderkolben tragen auf der hinteren Seite taschenartige einseitig offene Kammern, die zum Schnellwechsel derselben über knopfartige Verdickungen der hydraulischen Arbeitszylinder-Kolbenstangen geschoben werden. Hierdurch entsteht eine gelenkige Verbindung zwischen der Kolbenstange und dem Förderkolben, so daß der Kolben dem Förderzylinder optimal angeglichen ist und Verschleiß beider Teile auf ein Minimum beschränkt wird.The surfaces sliding in front of each other inside the mass feed container are armored and there are cleaning openings and in the bottom of the bulk feed container Openings for the introduction of liquid media to change the consistency of the conveyed material arranged. The delivery pistons carry pocket-like one-sided on the rear side open chambers that allow the quick change of the same via button-like thickenings of the hydraulic working cylinder piston rods are pushed. This creates an articulated connection between the piston rod and the delivery piston, so that the piston is optimally aligned with the delivery cylinder and both parts wear is kept to a minimum.

In den Figuren ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsart dargestellt und zeigt in F i g. 1 eine Seitenansicht, F i g. 2 eine Draufsicht, F i g. 3 eine Vorderansicht und in F i g. 4 einen Schnitt durch eine Förderkolbenbefestigung.The subject matter of the invention is shown in an exemplary manner in the figures Embodiment shown and shows in F i g. 1 is a side view, FIG. 2 one Top view, FIG. 3 is a front view and in FIG. 4 a section through a Delivery piston attachment.

Der Grundrahmen 1 ist in F i g. 1 mit einer Fahrachse und einer anklappbaren Stütze ausgestattet. Auf dem Grundrahmen 1 sind parallel zwei hydraulische Arbeitszylinder 2 an einem Wasserbehälter 3 angeflanscht. Die Kolbenstangen 4 der hydraulischen Arbeitszylinder 2 ragen durch den Wasserkasten 3 hindurch bis in die Förderzylinder 5 und tragen an ihren vorderen Enden je einen Förderkolben 6. Die beiden Förderzylinder 5 sind gleichachsig zu den hydraulischen Arbeitszylindern 2 auf der gegenüberliegenden Seite des Wasserkastens 3 an diesem befestigt. Mit ihrem anderen offenen Ende sind die Förderzylinder 5 mit dem Masseaufgabebehälter 7 verbunden. Durch die gegenüberliegende Wand mündet die Förderleitung 8' mit einem etagenförmigen Endstück als ZuteiIrohr 8 in den Masseaufgabebehälter 7 ein. Dieses ist in einer Lagerbuchse 9 drehbar und wird am tieferen Ende von einem Schwenkhebel 10 umfaßt, welcher an einem in der verlängerten Achse des Förderrohres 8' in der Behälterwand gelagerten Zapfen 11 befestigt ist. Am aus dem Masseaufgabebehälter 7 hinausragenden Ende des Zapfens 11 ist ein Doppel-Schwinghebel 12 angeordnet, an dessen Enden hydraulische Arbeitszylinder 13 angelenkt sind, die das Verschwenken des etagenförmigen Zuteilrohres 8 im Innern des Masseaufgabebehälters 7 wechselweise vor die Öffnungen der Förderzylinder 5 bewirken, und zwar abgestimmt auf die jeweiligen Saug- oder Druckhübe der darin bewegten Kolben 6. Die im Masseaufgabebehälter 7 aneinander vorbeigleitenden Teile im Bereich der Förderrohranschlußstelle am Masseaufgabebehälter und der Schwenkhebel 10 sind mit verschleißfesten Platten gepanzert oder aus verschleißfestem Material hergestellt.The base frame 1 is shown in FIG. 1 equipped with a travel axis and a foldable support. On the base frame 1, two hydraulic working cylinders 2 are flanged to a water tank 3 in parallel. The piston rods 4 of the hydraulic working cylinders 2 protrude through the water tank 3 into the delivery cylinder 5 and each have a delivery piston 6 at their front ends. The two delivery cylinders 5 are coaxially attached to the hydraulic working cylinders 2 on the opposite side of the water tank 3 . At their other open end, the delivery cylinders 5 are connected to the bulk feed container 7. The conveying line 8 ′ opens through the opposite wall with a tiered end piece as a feed pipe 8 into the mass feed container 7. This is rotatable in a bearing bushing 9 and is encompassed at the lower end by a pivot lever 10 which is attached to a pin 11 mounted in the extended axis of the conveyor pipe 8 'in the container wall. At the end of the pin 11 protruding from the mass feed container 7, a double rocking lever 12 is arranged, at the ends of which hydraulic working cylinders 13 are articulated, which cause the tiered metering pipe 8 to pivot in the interior of the mass feed container 7 alternately in front of the openings of the delivery cylinders 5, namely matched to the respective suction or pressure strokes of the piston 6 moving therein. The parts sliding past each other in the mass feed container 7 in the area of the feed pipe connection point on the mass feed container and the pivot lever 10 are armored with wear-resistant plates or made of wear-resistant material.

Zur Vermehrung der durch die radiale Schwenkbewegung ohnehin erzielten Rührwirkung ist das schwenkbare Zuteilrohr 8 mit Mischarmen 14 und einem starren oder elastischen Räumer 15 versehen, welcher das Absetzen des Fördergutes auf dem Boden des Masseaufgabebehälters 7 verhindert. Zu diesem Zwecke ist der Boden des Masseaufgabebehälters 7 so geformt, daß er der Form des Zuteilrohres 8 angepaßt ist und in jeder Zuteilrohrstellung der Abstand zwischen Zuteilrohr 8 und Boden des Masseaufgabebehälters 7 etwa gleich ist. Für die Reinigung des Masseaufgabebehälters 7 ist an der unteren Seite eine Reinigungsöffnung 20 angeordnet. Ferner sind vorzugsweise am Boden des Masseaufgabebehälters 7 Anschlüsse 21 vorgesehen, durch welche flüssige Bestandteile dem Fördergut beigemischt werden, um gegebenenfalls die Konsistenz des Fördergutes während des Pumpvorganges zu verändern.To increase the agitating effect already achieved by the radial pivoting movement, the pivotable metering pipe 8 is provided with mixing arms 14 and a rigid or elastic scraper 15, which prevents the material being conveyed from settling on the bottom of the bulk feed container 7. For this purpose, the bottom of the mass feed container 7 is shaped so that it is adapted to the shape of the metering tube 8 and the distance between the metering tube 8 and the bottom of the mass feed container 7 is approximately the same in each metering tube position. A cleaning opening 20 is arranged on the lower side for cleaning the bulk feed container 7. Furthermore, connections 21 are preferably provided on the bottom of the bulk feed container 7, through which liquid constituents are mixed with the material to be conveyed, in order, if necessary, to change the consistency of the material to be conveyed during the pumping process.

Der zwischen den hydraulischen Arbeitszylindern 2 und den Förderzylindern 5 angeordnete Wasserbehälter 3 besitzt einen Frischwasserzulauf 16 und Gebrauchtwasserabläufe 17 und Schnellverschluß-Reinigungsöffnungen 18. In dem unteren Teil ist der Wasserbehälter 3 durch eine Trennwand 19 geteilt. Während des Förderbetriebes wird das im Wasserbehälter 3 befindliche Wasser von den Förderkolben 6 in die Förderzylinder 5 hineingesogen und zurückgedrückt. Es dient auf diese Weise der Spülung und Schmierung der Förderzylinder 5 und Förderkolben 6. Etwa an den Förderkolben 6 vorbeigelangte Rückstände des Fördergutes gelangen somit in den Wasserbehälter 3. Durch die Gebrauchtwasserabläufe 17 kann das trübe Wasser ablaufen bzw. durch die Reinigungsöffnungen 18 etwaige Ablagerungen entfernt werden.The water tank 3 arranged between the hydraulic working cylinders 2 and the delivery cylinders 5 has a fresh water inlet 16 and used water outlets 17 and quick-release cleaning openings 18. In the lower part, the water tank 3 is divided by a partition 19. During the delivery operation, the water in the water tank 3 is sucked into the delivery cylinder 5 by the delivery piston 6 and pushed back. In this way, it serves to flush and lubricate the delivery cylinders 5 and delivery pistons 6. Any residues of the conveyed goods that have passed the delivery pistons 6 thus end up in the water container 3.The cloudy water can drain through the used water drains 17 or any deposits can be removed through the cleaning openings 18 will.

Die Förderkolben 6 können zur Kontrolle oder zum Auswechseln in an sich bekannter Weise, beispielsweise in den Wasserkasten 3, gezogen werden. Zum schnellen Auswechseln der Förderkolben 6 ist nach F i g. 4 auf der dem Fördergut abgewendeten Seite eine taschenartige Aufhängung 26 angeordnet, die über eine knopfartige Verdickung 27 der Kolbenstange 4 geschoben wird.The delivery piston 6 can be used for checking or replacing in a known manner, for example in the water tank 3, are drawn. To the rapid replacement of the delivery piston 6 is shown in FIG. 4 on the conveyed item remote side arranged a pocket-like suspension 26, which has a button-like Thickening 27 of the piston rod 4 is pushed.
