Description

Pumpe, insbesondere Betonpumpe, mit großer Baulänge und mit einem hydraulisch betätigten Antriebskolben Die Erfindung betrifft eine Pumpe, insbesondere Betonpumpe, mit großer Baulänge und mit einem hydraulisch betätigten Antriebskolben, der in einem Antriebszylinder gleitet und der mit einem in einem Arbeitszylinder gleitenden Arbeitskolben durch eine Kolbenstange verbunden ist.Pump, especially concrete pump, with a large overall length and with a hydraulically operated drive piston The invention relates to a pump, in particular Concrete pump, with a large overall length and with a hydraulically operated drive piston, which slides in a drive cylinder and the one with one in a working cylinder sliding working piston is connected by a piston rod.

Betonpumpen bisher bekannter Bauart haben große Baulängen, weil der Arbeitszylinder, in dem der Arbeitskolben gleitet, und der Antrieb axial hintereinander angeordnet sind. Diese Bauweise bringt insofern große Nachteile mit sich. Der Transport solcher Pumpen ist schwierig, und bei anfallenden Reparaturen ist ein Auseinandernehmen der ganzen Pumpanlage nicht zu umgehen.Concrete pumps of the previously known type have great overall lengths because of the Working cylinder, in which the working piston slides, and the drive axially one behind the other are arranged. In this respect, this design has major disadvantages. The transport Such pumps are difficult and dismantling when repairs are required the whole pumping station cannot be avoided.

Es sind auch Betonpumpen bekannt, bei denen zum Zwecke der Überprüfung oder Reparatur defekter Kolbenmanschetten oder ausgeschliffener Arbeitszylinder ohne wesentliche Demontagen nach Belieben Kolbenkopf oder Arbeitszylinder relativ freigelegt werden können. Aber auch diese Bauart erleichtert den Transport in keiner Weise und auch bei solchen Pumpen sind einfache Wartungsarbeiten mit einem großen Aufwand verbunden.There are also concrete pumps known where for the purpose of checking or repair of defective piston sleeves or polished working cylinders Piston head or working cylinder relative without significant dismantling at will can be exposed. But even this design does not facilitate transport in any Way and even with such pumps are simple maintenance with a big one Effort involved.

Hier greift die Erfindung ein, deren Aufgabe es ist, die geschilderten Nachteile zu beseitigen. Sie besteht darin, daß bei derartigen Pumpen zwischen Arbeits-und Antriebszylinder ein Schwenk- und Schnellverschluß, bestehend aus einem um einen Bolzen schwenkbaren Verschlußmittelstück mit Schnellverschlußschrauben, angeordnet ist. Der Förderkolben wird also aus dem Zylinder heraus in das Mittelstück des Verschlusses gezogen.This is where the invention comes into play, the object of which is to provide the described Eliminate disadvantages. It consists in the fact that in such pumps between working and Drive cylinder a swivel and quick release, consisting of one to one Bolt pivotable locking center piece with quick release screws, arranged is. The delivery piston is thus out of the cylinder into the middle piece of the closure drawn.

Durch die Erfindung kann das Aggregat schnell und einfach auf die Hälfte der eigentlichen Bau- bzw. Transportlänge verkürzt werden. Außerdem ergibt sich der Vorteil, daß der bzw. die Förderkolben leicht überprüft und bei Bedarf ohne besondere Montagearbeiten ausgewechselt werden können. Auch besteht nunmehr bei Verwendung von genormten Schwenk-und Schnellverschlüssen die Möglichkeit, auf einfachste Weise größere oder kleinere Antriebsaggregate bzw. ebensolche Förderzylinder gegeneinander auszutauschen, und das Gerät den jeweils herrschenden Betriebsbedingungen weitgehendst anzupassen. Besonders bei Zweizylindergeräten mit Hydraulikantrieb, bei denen nur eine Ölhydraulik erforderlich ist, machen sich diese Vorteile besonders bemerkbar.Through the invention, the unit can quickly and easily on the Half of the actual construction or transport length. Also results the advantage that the delivery piston or pistons are easily checked and if necessary can be replaced without special assembly work. Also now exists when using standardized swivel and quick-release fasteners the possibility of opening simplest way larger or smaller drive units or just such delivery cylinders exchange against each other, and the device the prevailing operating conditions adapt as much as possible. Especially with two-cylinder devices with hydraulic drive, where only one oil hydraulic system is required, these advantages make themselves particularly special noticeable.

Im folgenden ist ein Ausführungsbeispiel der Erfindung unter Bezugnahme auf die Abbildungen näher erläutert, und zwar zeigt A b b. 1 Einzylinderbetonpumpe mit dem Schwenk-und Schnellverschluß, A b b. TI Zweizylinderbetonpumpe mit Schwenk-und Schnellverschluß.The following is an embodiment of the invention by reference explained in more detail on the figures, namely A b b. 1 single cylinder concrete pump with the swivel and quick release, A b b. TI two-cylinder concrete pump with swivel and Quick release.

Der Förderkolben 1, der im Förderzylinder 2 der Betonpumpe läuft, wird durch ein Hydraulikaggregat 3 angetrieben. Zwischen diesem und dem Förderzylinder 2 ist das Verschlußmittelstück 4 angeordnet, das um den Bolzen 5 geschwenkt und durch Schnellverschlußschrauben 6 im Betriebszustand fixiert werden kann. Im ausgeschwenkten Zustand kann man nach Entfernen des Bolzens 5 das Gerät in zwei Teile zerlegen. Bei der Zweizylinderbetonpumpe nach A b b.11 drückt das durch den Ölzulauf 7 einströmende Öl den Hydraulikkolben 8 vor sich her und das im Zylinderraum 9 befindliche öl wirkt über das Umlaufrohr 10 auf den zweiten Hydraulikkolben 11, der seinerseits eine Hubbewegung ausführt und das im Zylinderraum 15 befindliche Öl aus dem Ölauslauf 12 nach außen fördert. Ein nicht dargestelltes Umsteuerventil, das beispielsweise elektrisch, mechanisch oder magnetisch gesteuert wird, ändert öl- und somit Hubrichtung.The delivery piston 1, which runs in the delivery cylinder 2 of the concrete pump, is driven by a hydraulic unit 3. Between this and the delivery cylinder 2, the locking center piece 4 is arranged, which can be pivoted about the bolt 5 and fixed by quick-release screws 6 in the operating state. In the swiveled-out state, after removing the bolt 5, the device can be disassembled into two parts. In the case of the two-cylinder concrete pump according to A b b.11, the oil flowing in through the oil inlet 7 pushes the hydraulic piston 8 in front of it and the oil in the cylinder chamber 9 acts via the circulating pipe 10 on the second hydraulic piston 11, which in turn performs a stroke movement and that in the cylinder chamber 15 promotes oil from the oil outlet 12 to the outside. A reversing valve, not shown, which is controlled electrically, mechanically or magnetically, for example, changes the direction of the oil and thus of the stroke.

Eine stufenlos arbeitende Ölpumpe für die Hydraulik kann verwendet werden, um die Leistung den Erfordernissen entsprechend variieren zu können.An infinitely variable oil pump for the hydraulics can be used in order to be able to vary the performance according to requirements.
