Fig. 1 zeigt die Vorrichtung 1 zum Pumpen von Beton, die auf
einem Lkw-Fahrgestell 2 fest montiert ist. Am hinteren Teil
des Fahrgestells 2 befindet sich ein Pumpenantrieb 3. Aus
dem Pumpenantrieb münden Rohrsegmente 4, die zusammen eine
Pumpenleitung 5 bilden.Fig. 1 shows the
Die Rohrsegmente 4 sind jeweils an Tragarmsegmenten 6
befestigt. Die Tragarmsegmente 6 sind jeweils über Gelenke 7
gelenkig miteinander verbunden. Ebenso sind die Rohrsegmente
4 an den Gelenken 7 gelenkig miteinander verbunden.The
Wie in Fig. 1 dargestellt, sind die Tragarmsegmente 6 zum
Transport der Vorrichtung 1 aufeinander gefaltet. In einer
Arbeitsstellung bilden die Tragarmsegmente 6 einen
auskragenden Tragarm 8, der über ein Drehgelenk 9 um eine
vertikale Achse drehbar auf dem Lkw-Fahrgestell 2 gelagert
ist. Das Überführen des Tragarmes 8 von seiner
Transportstellung in seine Arbeitsstellung erfolgt mittels
mehrerer Hydraulikzylinder 10. Wenn sich die Vorrichtung 1
in ihrer Arbeitsstellung befindet, befindet sich ein
Leitungsende 11 in der Pumpenleitung 5 am Ende des am
weitesten auskragenden Tragarmsegmentes 6.As shown in Fig. 1, the
Bei einem der Tragarmsegmente 6 handelt es sich um ein
teleskopierbares Tragarmsegment 12, das ein ausziehbares
Teilsegment 13 und ein festes Teilsegment 14 aufweist. Das
ausziehbare Teilsegment 13 ist in Achsrichtung teleskopisch
ausziehbar in dem festen Teilsegment gelagert. Das
Teleskopieren des teleskopierbaren Tragarmsegmentes 12
erfolgt über einen angedeutet dargestellten, hydraulischen
Teleskopantrieb 15.One of the
Wie aus Fig. 2 ersichtlich ist, befindet sich parallel zu
dem Rohrsegment 4 des teleskopierbaren Tragarmsegmentes 12
ein Zusatzrohrsegment 16. Dieses Zusatzrohrsegment 16 wird
von einer an dem teleskopierbaren Tragarmsegment 12
angebrachten Zuführeinrichtung 17 gehalten. Die
Zuführeinrichtung 17 weist eine, um eine Achse parallel zur
Längserstreckung des teleskopierbaren Tragarmsegmentes 12
verlaufenden Drehachse schwenkbare Halterung 18 auf. In der
Halterung 18 ist das Zusatzrohrsegment 16 in Richtung seiner
Längsachse axial begrenzt verschieblich gelagert. Eine
angedeutet dargestellte verdickte Feder 19 in der Halterung
18 spannt dabei das Zusatzrohrsegment 16 in Richtung des
Teleskopiervorganges beim Überführen des teleskopierbaren
Tragarmsegmentes 12 von seiner zusammengeschobenen
Ausgangsstellung in seine teleskopierte Stellung vor. Die
Halterung 18 ist von einer ersten Stellung, in welcher das
Zusatzrohrsegment 16 außerhalb des von den Rohrsegmenten 4
eingenommenen Volumens angeordnet ist, in eine zweite
Stellung überführbar, in welcher zumindest ein Endabschnitt
20 des Zusatzrohrsegmentes 16 mit zumindest einem
Endabschnitt 21 eines der Rohrsegmente 4 fluchtet. Aus Fig.
3 ist die Halterung 18 in ihrer zweiten Stellung entnehmbar.
Zudem ist in den Fig. 2 und 3 entnehmbar, daß in Richtung
der Längserstreckung des teleskopierbaren Tragarmsegmentes
12 immer ein Endabschnitt 20 des Zusatzrohrsegmentes 16 im
wesentlichen auf gleicher Höhe mit einem der Endabschnitt 21
der Rohrsegmente 4 angeordnet ist. Den Fig. 2 und 3 kann
ebenfalls entnommen werden, daß sich zwischen dem nahe dem
Zusatzrohrsegment 16 angeordneten Rohrsegmenten 4 eine
Trennstelle 22 befindet. An dieser Trennstelle 22 sind die
Endabschnitte 21 der zugehörigen Rohrsegmente 4 durch eine
Klauenkupplung 23 trennbar verbunden. In Fig. 6 ist die
Klauenkupplung 23 in einer geschnittenen Seitenansicht
dargestellt. Wie aus Fig. 6 entnehmbar ist, weist einer der
Endabschnitte 21 der Rohrsegmente 4 schwenkbar gelagerte
Klauen 24 auf, die von einer geschlossenen Stellung in eine
geöffnete Stellung überführbar sind, wobei die Klauen 24
durch Federn 25 in ihrer geschlossenen Stellung vorgespannt
sind. In der geschlossenen Stellung hintergreifen die Klauen
24 einen Absatz 26 des jeweils anderen Endabschnittes 21 des
zugeordneten Rohrsegmentes 4. Zudem ist ersichtlich, daß
einer der Endabschnitte 21 der Rohrsegmente 4 stirnseitig
mit einer ringförmigen Ausnehmung 27 versehen ist, in der im
zusammengesteckten Zustand der Rohrsegmente 4 ein
zylinderringförmiger Vorsprung 28 aufgenommen ist. As can be seen from Fig. 2, is located parallel to
the
Zusätzlich ist in der ringförmigen Ausnehmung ein
zylinderringförmiges Dichtelement 29 angeordnet, in dem sich
der zylinderringförmige Vorsprung stirnseitig abstützt.
Dadurch sind im zusammengesteckten Zustand die Rohrsegmente
4 flüssigkeitsdicht miteinander verbunden. Die Klauen 24
können durch eine angedeutet dargestellte
Hydraulikvorrichtung hydraulisch betätigt werden.In addition, there is a in the annular recess
arranged
Die Endabschnitte 20 des Zusatzrohrsegmentes 16 sind
entsprechend der Klauenkupplung 23 gestaltet derart, daß das
Zusatzrohrsegment 16 zwischen zwei einander zugeordneten
Endabschnitten 20 der Rohrsegmente 4 eingesetzt und
verkuppelt werden kann.The
Wie aus Fig. 3 ersichtlich ist, läßt sich das
teleskopierbare Tragarmsegment 12 in eine teleskopierte
Stellung überführen, in welcher das Zusatzrohrsegment 16
zwischen dem an dem ausziehbaren Teilsegment 13 angebrachten
Rohrsegment 4 und dem am festen Teilsegment 14 angebrachten
Rohrsegment 4 positionieren. Das teleskopierbare
Tragarmsegment 12 kann dabei in mehreren teleskopierten
Stellungen arretiert werden.As can be seen from Fig. 3, it can
telescopic
In einer zweiten Ausführungsform der erfindungsgemäßen
Vorrichtung 1 ist das Zusatzrohrsegment 16 um eine Achse
senkrecht zur Längserstreckung des teleskopierbaren
Tragsegmentes 12 schwenkbar in der Zuführeinrichtung 17
gehalten. Die Zuführeinrichtung 17 erlaubt es darüber
hinaus, das Zusatzrohrsegment 16 senkrecht zur
Längserstreckung des teleskopierbaren Tragarmsegmentes 12 zu
verschieben.In a second embodiment of the
Im folgenden wird die Wirkungs- und Funktionsweise der erfindungsgemäßen Vorrichtung näher erläutert:In the following the effectiveness and functioning of the Device according to the invention explained in more detail:
Beim Überführen der erfindungsgemäßen Vorrichtung 1 von
ihrer Transportstellung in die Arbeitsstellung, werden die
in Transportstellung aufeinandergefalteten Tragarmsegmente 6
und 12 derart entfaltet, daß sie einen auskragenden Tragarm
8 bilden. Anschließend wird das teleskopierbare
Tragarmsegment 12 von seiner zusammengeschobenen
Ausgangsstellung in eine teleskopierte Stellung überführt,
wobei zunächst die Rohrsegmente 4 an der Trennstelle 22
durch die Klauenkupplung 23 getrennt werden. Dadurch, daß
eines der Rohrsegmente 4 an dem ausziehbaren Teilsegment 13
angebracht ist, werden die zuvor an der Trennstelle 22
miteinander verbundenen Rohrsegmente 4 voneinander
beabstandet, wenn das teleskopierbare Tragsegment 12 in eine
teleskopierte Stellung überführt wird. Es handelt sich dabei
um eine erste teleskopierte Stellung, in welcher der Abstand
zwischen den beiden voneinander beabstandeten Rohrsegmenten
4 größer als die Länge des Zusatzrohrsegmentes 16 ist.When transferring the
Nun wird das Zusatzrohrsegment 16 mit Hilfe der
Zuführeinrichtung 17 zwischen den beiden Endabschnitten 21
der beiden voneinander beabstandeten Rohrsegmente 4
positioniert. Dazu wird die Halterung 18 von ihrer ersten
Stellung in die zweite Stellung überführt, in welcher die
Endabschnitte 20 des Zusatzrohrsegmentes 16 mit den
Endabschnitten 21 der voneinander beabstandeten Rohrsegmente
4 fluchten. Anschließend wird das teleskopierte
Tragarmsegment 12 in eine zweite teleskopierte Stellung
überführt, in der der Abstand der beiden Endabschnitte 21
der voneinander beabstandeten Rohrsegmente 4 geringer ist
als der Abstand der Endabschnitte 20 des Zusatzrohrsegmentes
16, wodurch die voneinander beabstandeten Rohrsegmente 4 und
das Zusatzrohrsegment 16 ineinandergesteckt werden. Dabei
wird das Zusatzrohrsegment 16 entgegen der Federkraft der
angedeutet dargestellten Feder 19 durch den Druck des am
ausziehbaren Teilsegment 13 angebrachten Rohrsegmentes 4 in
das am festen Teilsegment 14 angebrachte Rohrsegment 4
hineingedrückt. Da die Endabschnitte sowohl des
Zusatzrohrsegmentes, als auch der Rohrsegmente 4 in gleicher
Weise gestaltet sind, bilden auch die zusammengefügten
Endabschnitte 20 bzw. 21 des Zusatzrohrsegmentes 16 und der
Rohrsegmente 4 jeweils Klauenkupplungen.Now the
Bei der in den Fig. 7 und 8 dargestellten zweiten
Ausführungsform der erfindungsgemäßen Vorrichtung 1 erfolgt
das Anbringen des Zusatzrohrsegmentes 16 auf die gleiche
Weise, jedoch mit dem Unterschied, daß das Zusatzrohrsegment
16 nicht durch eine Schwenkbewegung zwischen den beiden
voneinander beabstandeten Rohrsegmenten 4 angeordnet wird,
sondern durch ein Verschieben quer zur Längserstreckung des
teleskopierbaren Tragarmsegmentes 12 und ein anschließendes
Kippen um eine Achse senkrecht zur Längserstreckung des
teleskopierbaren Tragarmsegmentes 12.In the second shown in FIGS. 7 and 8
Embodiment of the
Zur Demontage des Zusatzrohrsegmentes 16 werden bei beiden
Ausführungsformen zunächst die aus den Endabschnitten
gebildeten Klauenkupplungen 23 hydraulisch geöffnet.
Anschließend wird das teleskopierbare Tragarmsegment 12
wieder in seine erste teleskopierte Stellung überführt,
wodurch die Endabschnitte 20 und 21 jeweils voneinander
getrennt werden. Die Kraft der Feder 19 bewirkt dabei, daß
die Endabschnitte 20 und 21 des Zusatzrohrsegmentes 16 und
des am festen Teilsegment 14 angeordneten Rohrsegmentes 4
voneinander beabstandet werden. Nun kann die
Zuführeinrichtung 17 wieder in ihre erste Stellung
rücküberführt werden, in welcher das Zusatzrohrsegment 16
außerhalb des von den Rohrsegmenten 4 eingenommenen Volumens
angeordnet ist.To dismantle the
Die erfindungsgemäße Vorrichtung 1 erlaubt es, bei
vergleichsweise geringen Abmessungen eine große Förderhöhe
zu erzielen.The
