Description

Die Erfindung betrifft eine Betoniereinrichtung mit einer an einem Fahrgestell um eine Vertikalachse drehbaren Drehsäule, einem um eine Horizontalachse an der Drehsäule verschwenkbar angeordneten, mindestens zwei relativ zueinander bewegbare langgestreckte Mastausleger aufweisenden Verteilermast, einem am freien Ende des Verteilermasts angelenkten Verteilerarm und einer sich von der Drehsäule zum Verteilerarm entlang dem Verteilermast erstreckenden Förderleitung für den Beton, wobei der Verteilermast aus mindestens zwei Mastauslegern besteht, der Verteilerarm um eine zur Mastachse senkrechte Querachse und eine dazu senkrechte Längsachse schwenkbar am Verteilermast angeordnet ist, und die Förderleitung am verteilerarmseitigen Ende des Verteilermasts befestigt und mit dem Verteilermast mitnehmbar ist.The invention relates to a concreting device with a rotating column that can be rotated about a vertical axis on a chassis, a pivoting boom that is arranged to pivot about a horizontal axis on the rotating column, has at least two elongated mast booms that can be moved relative to one another, a distributor arm articulated at the free end of the distributor mast, and a distributor arm that is pivoted from the rotating column Conveyor line for the concrete extending to the distributor arm along the distributor mast, the distributor mast consisting of at least two mast brackets, the distributor arm being arranged on the distributor mast so as to be pivotable about a transverse axis perpendicular to the mast axis and a longitudinal axis perpendicular thereto, and the conveyor line being fastened to and at the end of the distributor mast on the side of the distributor arm the placing boom is portable.

Betoniereinrichtungen dieser Art sind vor allem zum Einbringen von Beton in Tunnelschalungen bestimmt, die in mehrere in Streckenlängs- und -umfangsrichtung verteilt angeordnete verschließbare Einfüllöffnungen aufweisen, die durch die Betoniereinrichtung mittels eines am Ende des Verteilerarms angeordneten Mundstücks mit Beton beaufschlagt werden. Um diesen Vorgang zu erleichtern und zu beschleunigen ist es aus der GB-A-2 008 656 bekannt, den Verteilermast als zwei- oder dreiarmigen Knickmast auszubilden, dessen Mastabschnitte im Betriebszustand in Strecklage gegeneinander ausfluchtbar und im Transportzustand gegeneinander anklappbar sind. Um das Mundstück der Förderleitung auch an unterschiedlich ausgerichtete Einfüllstutzen der Schalung anschließen zu können, ist der Verteilerarm sowohl um die Querachse als auch um die Längsachse des endseitigen Mastabschnitts verschwenkbar. Durch eine geeignete Anordnung der Betriebsgelenke und Bemessung der Abmessungen der Mastabschnitte ist es zwar möglich, die Betoniereinrichtung auch in relativ niedrigen Tunnelbauten einzusetzen. Je kleiner die Ausfalthöhe der Mastabschnitte ist, um so kleiner ist jedoch die Reichweite des Verteilermasts in Streckenlängsrichtung. Der Bearbeitungshöhe sind daher Grenzen gesetzt, die bei dieser Betoniereinrichtung mit Knickmast bei ca. 4 bis 5 m liegen.Concreting devices of this type are primarily intended for the introduction of concrete into tunnel formwork, which have a plurality of closable filling openings distributed in the longitudinal and circumferential directions, which are supplied with concrete by the concreting device by means of a mouthpiece arranged at the end of the distributor arm. In order to facilitate and accelerate this process, it is known from GB-A-2 008 656 to design the distribution boom as a two- or three-arm articulated mast, the mast sections of which can be aligned with one another in the operating state in the extended position and can be folded against one another in the transport state are. In order to be able to connect the mouthpiece of the delivery line to differently aligned filler neck of the formwork, the distributor arm can be pivoted both about the transverse axis and about the longitudinal axis of the mast section at the end. A suitable arrangement of the operating joints and dimensioning of the dimensions of the mast sections make it possible to use the concreting device even in relatively low tunnel structures. However, the smaller the unfolding height of the mast sections, the smaller the range of the placing mast in the longitudinal direction. The processing height is therefore limited, which are about 4 to 5 m in this concreting facility with an articulated mast.

Aus der GB-A-2 182 697 ist es zwar bei einer Bolzensetzmaschine mit Bohrer und Betonierschlauch an sich bekannt, einen Betonierschlauch zum Einbringen von Beton in ein zuvor gebohrtes Gesteinsloch auf einer Schlauchtrommel auf- und abzuwickeln. Der Betonierschlauch wird dort jedoch beim Auf- und Abwickeln durch ein biegsames Führungsrohr unmittelbar bis zu der auszubetonierenden Bohrung hindurchgeführt, ohne mit einem Verteilermast verbunden zu sein. Auf diese Weise läßt sich mit dem Betonierschlauch nur eine relativ kleine Reichweite überwinden, so daß ein Einsatz zum Betonieren in Tunnelbauten nicht möglich erscheint.From GB-A-2 182 697 it is known per se in a bolt-setting machine with a drill and concreting hose to wind and unwind a concreting hose for introducing concrete into a previously drilled rock hole on a hose reel. The concreting hose, however, is passed through a flexible guide tube directly up to the hole to be concreted during winding and unwinding, without being connected to a placing boom. In this way, only a relatively small range can be covered with the concreting hose, so that use for concreting in tunnel structures does not appear possible.

Aus der EP-A-0 066 755 ist eine Schlauchführungseinrichtung für eine Betonspritzanlage bekannt, bei der ein Schlauch im Inneren einer in einem um eine horizontale Achse schwenkbaren Ausleger axial verschiebbar angeordneten Lanze angeordnet ist. Der Schlauch weist dabei eine feste Länge auf und die Lanze ist an sich nicht teleskopierbar, so daß die Überwindung größerer Strecken mit dieser Anordnung nicht möglich ist.From EP-A-0 066 755 a hose guide device for a concrete spraying system is known, in which a hose is arranged in the interior of a lance arranged axially displaceably in a boom that can be pivoted about a horizontal axis. The hose shows a fixed length and the lance is not telescopic per se, so that long distances cannot be overcome with this arrangement.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, eine Betoniereinrichtung der eingangs angegebenen Art zu entwickeln, die trotz relativ großer Reichweite in sehr niedrigen Tunnelbauten einsetzbar ist.Proceeding from this, the object of the invention is to develop a concreting device of the type specified at the outset which, despite its relatively long range, can be used in very low tunnels.

Zu Lösung dieser Aufgabe wird die im Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To achieve this object, the combination of features specified in claim 1 is proposed. Further advantageous refinements and developments of the invention result from the dependent claims.

Die erfindungsgemäße Lösung geht von dem Gedanken aus, daß mit einem Verteilermast, der ausschließlich aus gegeneinander teleskopierbaren Mastabschnitten zusammengesetzt ist, keine Ausfaltung und dadurch auch keine zusätzliche Ausfalthöhe erforderlich ist, die die bearbeitbare Tunnelhöhe nach unten hin begrenzt. Dementsprechend wird gemäß der Erfindung vorgeschlagen, daß der Verteilermast aus mindestens zwei in ihrer Längserstreckung teleskopierbaren Mastauslegern besteht, und daß die zumindest teilweise als biegsamer Schlauch ausgebildete Förderleitung auf einer an der Drehsäule angeordneten Schlauchtrommel selbsttätig aufwickelbar und von dieser nach Maßgabe der Teleskopausladung des Verteilermasts abwickelbar ist.The solution according to the invention is based on the idea that with a placing boom, which is composed exclusively of telescopic mast sections, no unfolding and therefore no additional unfolding height is required, which limits the machinable tunnel height downwards. Accordingly, it is proposed according to the invention that the distribution boom consists of at least two telescopic boom extensions, and that the delivery line, which is at least partially designed as a flexible hose, can be automatically wound up on a hose drum arranged on the rotating column and can be unwound from it in accordance with the telescopic projection of the distribution boom .

Die Schlauchtrommel weist zweckmäßig einen in Aufwickelrichtung wirkenden motorischen, vorzugsweise hydraulischen Drehantrieb auf.The hose drum expediently has a motorized, preferably hydraulic, rotary drive acting in the winding direction.

Die Förderleitung weist zweckmäßig an ihrem verteilerarmseitigen Ende eine Rohrkupplung für den Anschluß an einen Betonierstutzen oder ein Betonierfenster einer Tunnelschalung auf. Um möglichst alle Anschlußstellen in einem Schalungswagen von einem festen Standort des Fahrgestells außerhalb des Schalungswagens erreichen zu können, ist der Verteilermast mit seiner Teleskopachse zweckmäßig zwischen einer um etwa 10° bis 20° schräg nach unten und einer etwa vertikal nach oben weisenden Lage um die Horizontalachse der Drehsäule verschwenkbar.The conveyor line expediently has a pipe coupling on its distributor arm end for connection to a concrete nozzle or a concrete window of a tunnel formwork. In order to be able to reach all connection points in a formwork carriage from a fixed location of the chassis outside the formwork carriage, the placing boom with its telescopic axis is expediently between an angle of about 10 ° to 20 ° downwards and an approximately vertically upward position around the horizontal axis the rotating column can be swiveled.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist der Verteilerarm an einer am verteilerarmseitigen Ende des letzten Mastabschnitts angelenkten, um eine vertikale Achse drehbaren Arbeitsbühne oder -kabine angeordnet. Die Förderleitung kann dort an ihrem verteilerarmseitigen Ende mit einer vorzugsweise mit Druckluft beaufschlagten Betonspritzdüse bestückt werden, mit der beispielsweise beim Tunnelvortrieb Spritzbeton zur vorläufigen Sicherung des Gebirges aufgetragen werden kann.According to an advantageous development of the invention, the distributor arm is arranged on a working platform or cabin which is articulated on the end of the last mast section on the distributor arm side and can be rotated about a vertical axis. At its end on the distributor arm side, the delivery line can be equipped with a concrete spray nozzle, preferably pressurized with compressed air, with which sprayed concrete can be applied, for example, during tunneling to temporarily secure the rock.

Die Betonversorgung erfolgt vorteilhafterweise über eine Betonpumpe und einen Materialaufgabebehälter, die beide unmittelbar am Fahrgestell angeordnet werden können.The concrete supply is advantageously carried out via a concrete pump and a material feed container, both of which can be arranged directly on the chassis.

Zur Vergrößerung der Reichweite des Verteilermasts und des Verteilerarms kann auch der Verteilerarm seinerseits aus mindestens zwei in ihrer Längserstreckung teleskopierbaren Armabschnitten zusammengesetzt werden.In order to increase the range of the placing boom and the placing arm, the placing arm can also have at least two in its longitudinal extent telescopic arm sections are assembled.

Die in der Zeichnung dargestellten fahrbaren Betoniereinrichtungen weisen beispielhaft ein als Einachshänger ausgebildetes Fahrgestell 10 auf. Grundsätzlich ist es möglich, statt des Einachshängers auch andere Fahrgestelle, beispielsweise einen Zweiachshänger, ein selbstfahrendes Fahrgestell mit Rad- oder Raupenfahrwerk oder ein LKW-Chassis zu verwenden.The mobile concreting devices shown in the drawing have, for example, a chassis 10 designed as a single-axle trailer. In principle, it is possible to replace the single-axle trailer with other chassis, such as a two-axle trailer, a self-propelled one Chassis with wheel or crawler chassis or a truck chassis to use.

Das Fahrgestell 10 weist eine an einem feststehenden Fuß 12 um eine vertikale Achse 14 drehbare Drehsäule 16 auf, an der ein Verteilermast 18 um eine Horizontalachse 20 mittels eines Hydrozylinders 22 schwenkbar gelagert ist. Der Verteilermast 18 ist bei den gezeigten Ausführungsbeispielen als vierarmiger Teleskopmast ausgebildet, der aus einem an der Drehsäule 16 angelenkten Grundausleger 24 und drei teleskopierbaren Telesopauslegern 24',24'',24''' besteht. Am freien Ende des letzten Teleskopauslegers 24''' befindet sich ein Verteilerarm 26, der um eine zur Teleskopachse senkrechte Querachse 30 beispielsweise um ± 30° sowie um eine zu dieser senkrechten Längsachse 30 um 360° schwenkbar ist. Entlang dem Verteilermast 18 und dem Verteilerarm 26 erstreckt sich eine Betonförderleitung 32,32', die über einen Materialaufgabebehälter 34 und eine Betonpumpe 36 mit Beton beaufschlagbar ist. Im Falle der Fig. 1 bis 4 ist die Förderleitung 32 als flexibler Schlauch ausgebildet, der auf einer an der Drehsäule 16 angeordneten Schlauchtrommel 38 teilweise aufgewickelt ist. Die Förderleitung 32 wird beim Teleskopieren der Teleskopausleger 24',24'',24''' von der Schlauchtrommel 38 abgezogen oder aufgewickelt. Letzteres erfolgt selbsttätig über einen in der Zeichnung nicht dargestellten, an der Schlauchtrommel 38 angreifenden hydraulischen Drehantrieb, der dafür sorgt, daß der Förderschlauch ständig unter Spannung gehalten wird, so daß er beim Zurückziehen der Teleskopausleger 24',24",24"' nicht zwischen den einzelnen Auflagen durchhängt, durchknickt oder faltet. Die Förderleitung 32 erstreckt sich mit ihrem gebogenen Endstück 32' über den Verteilerarm 26.The chassis 10 has a rotating column 16, which can be rotated about a vertical axis 14 on a fixed foot 12 and on which a placing boom 18 is pivotably mounted about a horizontal axis 20 by means of a hydraulic cylinder 22. In the exemplary embodiments shown, the placing boom 18 is designed as a four-arm telescopic mast, which consists of a basic boom 24 articulated on the rotating column 16 and three telescopic telescopic booms 24 ', 24'',24'''. At the free end of the last telescopic boom 24 '''there is a distributor arm 26 which can be pivoted about a transverse axis 30 perpendicular to the telescopic axis, for example by ± 30 ° and about a longitudinal axis 30 perpendicular to this, by 360 °. A concrete delivery line 32, 32 'extends along the placing boom 18 and the placing arm 26 and can be supplied with concrete via a material feed container 34 and a concrete pump 36. In the case of FIGS. 1 to 4, the delivery line 32 is designed as a flexible hose which is partially wound on a hose drum 38 arranged on the rotating column 16. The conveying line 32 is withdrawn or wound up from the hose drum 38 when the telescopic booms 24 ', 24'',24''' are telescoped. The latter takes place automatically via a hydraulic rotary drive, not shown in the drawing, which acts on the hose reel 38 and ensures that the delivery hose is kept under tension, so that it is pulled back the telescopic boom 24 ', 24 ", 24"' does not sag, buckle or fold between the individual supports. The delivery line 32 extends with its curved end piece 32 ′ over the distributor arm 26.

Bei den in Fig. 1 bis 3 und 5 gezeigten Ausführungsbeispielen mündet die Förderleitung 32' in ein Mundstück 40, das an die Einfüllstutzen 42 eines im Tunnel 44 angeordneten Schalungswagens 46 anschließbar ist. Wie aus den Fig. 2 und 3 zu ersehen ist, können von dem hinter dem Schalungswagen 46 im Tunnel positionierten Fahrgestell 10 aus sämtliche in Streckenlängs- und -umfangsrichtung des Schalungswagens 46 angeordneten Einfüllstutzen 42 durch Schwenken des Grundauslegers 24 um die Horizontalachse 20, durch Betätigen der Teleskopausleger 24',24'',24''' und durch Schwenken des Verteilerarms 26 um die Achsen 28 und 30 erreicht werden. Wie aus Fig. 2 zu ersehen ist, kann zur Vergrößerung der Reichweite zusätzlich auch noch der Verteilerarm 26 teleskopartig ausgezogen werden.
