Description

Verfahren und Vorrichtung zum Entfernen des bei Betriebspausen und Betriebsbeendigungen in den Betonförderrohren von Betonpumpvorrichtungen verbleibenden Betonrestes mittels eines flüssigen Druckmittels Die Einrichtungen, welche bei Bauanlagen zum Hochfördern von Beton, Mörtel u. dgl. Stoffen mittels Pumpvorrichtungen dienen, zeigen den Übelstand, daß das Förderrohr bei Beendigung jeder Betriebsperiode entleert werden muß, um ein Festsetzen und Hartwerden des Fördergutes in dem Förderrohr und damit dessen Unbrauchbarwerden zu vermeiden.Method and device for removing the during breaks in operation and Stops of operation remaining in the concrete delivery pipes of concrete pumping equipment Concrete residue by means of a liquid pressure medium The facilities that are used in construction serve for pumping up concrete, mortar and similar materials by means of pumping devices, show the drawback that the delivery pipe empties at the end of each operating period must be to a setting and hardening of the conveyed material in the conveyor pipe and thus avoiding it becoming unusable.

Diese Entleerungen werden entweder so vorgenommen, daß man die Förderrohrleitung auseinandernahm und die einzelnen Rohrstücke entleerte, oder man wandte eine Wasserspülung an, was den Nachteil hatte, daß der Beton dünnflüssig und unbrauchbar wurde. Diese bisherige Art der Entleerung war also jedenfalls eine sehr umständliche, zeitraubende und unvorteilhafte.These evacuations are carried out either in such a way that the delivery pipeline is opened disassembled and emptied the individual pieces of pipe, or you applied a water flush on, which had the disadvantage that the concrete was thin and unusable. These The previous type of emptying was in any case a very cumbersome and time-consuming one and unfavorable.

Die Erfindung bezieht sich auf ein Verfahren, welches es ermöglicht, bei Abschluß der Betriebsperiode oder bei Betriebspausen die Förderrohrleitung bis auf den letzten Rest derart zu entleeren, daß sie unmittelbar darauf für die Wiederaufnahme der nächsten Betriebsperiode geeignet ist und einer besonderen nachträglichen Reinigung nicht bedarf.The invention relates to a method which makes it possible at the end of the operating period or during breaks in operation, the delivery pipeline to to empty the last residue in such a way that it is immediately ready for resumption suitable for the next operating period and special subsequent cleaning not required.

Auf der Zeichnung ist die Anwendungsweise des neuen Verfahrens meinem Ausführungsbeispiel durch eine teilweise Schnittdarstellung veranschaulicht.In the drawing, the method of application of the new method is mine Embodiment illustrated by a partial sectional view.

An dem unteren waagerechten Ende des während des Betriebes mit Fördergut gefüllten Steigerohres 9 ist ein nach. außen durch einen Deckel ioa und gegen das Förderrohr 9 mittels eines Schiebers i i dicht abschließbarer Seitenbehälter io angeordnet, welcher den Vorschiebekörper 12 in Gestalt einer Gummikugel :enthält.At the lower horizontal end of the material to be conveyed during operation filled riser pipe 9 is an after. outside by a lid ioa and against that Conveying pipe 9 by means of a slide i i tightly lockable side container io arranged, which the advancing body 12 in the form of a rubber ball: contains.

Soll beim Betriebsende der Inhalt des Förderrohres 9 nach oben aus dem Rohr hinaus zur Verwendungsstelle gebracht werden, so wird der Schieber i i herausgezogen. Die Kugel 12, die in besonderer Ausführung einen Kern aus Eisen oder Blei enthalten kann, sinkt dann in das Rohr 9, und beim, Hinterherschicken von Wasser schiebt die Kugel i 2 das Fördergut oben aus dem Rohr 9 hinaus. Das hinter der Kugel befindliche Wasser dient hierbei nicht nur als Druckmittel, sondern auch zur Reinigung des Rohres g. Die Kugel 12 kann gegebenenfalls auch nach Abnahme des Deckels ioa und Öffnen des Schiebers i i mittels einer Stange in die Förderrohrleitung eingestoßen werden.Should at the end of operation, the content of the delivery pipe 9 upwards the pipe are brought out to the point of use, the slide i i pulled out. The ball 12, which has a core made of iron or in a special design May contain lead, then sinks into the pipe 9, and when, behind, water the ball i 2 pushes the material to be conveyed out of the pipe 9 at the top. That behind the ball The water present not only serves as a pressure medium, but also for cleaning of the pipe g. The ball 12 can optionally also after removing the cover ioa and opening the slide i i pushed into the conveying pipeline by means of a rod will.

Die Erfindung kann sowohl bei senkrechten als auch bei anders Zerichteten Förderrohren Anwendung finden.The invention can be used both in the case of vertical as well as in other cases Find conveying pipes application.

PATENTANSPRÜCHE i. Verfahren zum Entfernen des bei Betriebspausen und Betriebsbeendigungen in den Betonförderrohren von Betonpumpvorrichtungen verbleibenden Betonrestes mittels eines flüssigen Druckmittels, .dadurch gekennzeichnet, daß zwischen die in der Förderrohrleitung befindliche Betonsäule und dein hinter diese Säule zu schickenden Druckmittel ein gegen die Rohrwand abdichtender kolbenartiger Körper eingeschaltet wird, welcher einerseits eine Vermischung von Beton und Druckmittel verhindert und anderseits dadurch, daß er den Beton vor sich her treibt, die restlose Entleerung der Förderrohrleitung bewirkt. PATENT CLAIMS i. Procedure for removing the during breaks in operation and stoppages of operations remaining in the concrete delivery pipes of concrete pumping equipment Concrete residue by means of a liquid pressure medium. Characterized in that between the concrete column in the delivery pipe and the one behind this column to be sent pressure medium a piston-like body sealing against the pipe wall is switched on, which on the one hand a mixing of concrete and pressure medium prevented and on the other hand by the fact that he drives the concrete in front of him, the complete Causes emptying of the delivery pipeline. 2. Vorrichtung zur Ausführung des Verfahrens nach Anspruch i, dadurch gekerinzeichnet, daß der kolbenartige Körper (i2) eine mit einem Kern aus Eisen, Blei o. dgl. versehene Gummikugel ist. 2. Apparatus for carrying out the method according to claim i, characterized in that the piston-like body (i2) is a with a core made of iron, lead or the like. Provided rubber ball. 3. Vorrichtung nach Anspruch 2, gekennzeichnet durch: einen seitlich an der Förderrohrleitung angeordneten, gegen dieselbe absperrbaren Behälter (io) für den kolbenartigen Körper (i2), der mit einem die Einführung des kolbenartigen Körpers und einer Stazige zum Einstoßen des kolbenartigen Körpers in die Förderrohrleitung ermöglichenden abnehmbaren Deckel (ioa) versehen ist.3. Device according to claim 2, characterized by: a laterally arranged on the conveying pipeline, against the same lockable container (io) for the piston-like body (i2), the with one the introduction of the piston-like body and a rod for pushing in of the piston-like body in the delivery pipeline enabling removable cover (ioa) is provided.
