Definitions
- the invention relates to a concrete distribution mast for stationary and mobile concrete pumps with a plurality of articulated joints connected to articulated joints and a plurality of, preferably via pipe bends and rotary joints articulated interconnected, guided along the individual mast arms and attached to these pipe segments existing concrete delivery line.
- Known concrete distributor masts have mast arms that are designed with a closed box or tube profile ( DE 196 44 410 A1 ). With such a box or tube profile can be for the mast arms ensure good stability and torsional stiffness at relatively low weight.
- a box or tube profile has the disadvantage that a concrete delivery line, which is arranged in the interior of such a profile, can be made accessible only with considerable design effort to allow maintenance of the concrete delivery line. But if the concrete delivery line out of the mast arms, so elaborate pipe holder are required to hold the concrete delivery line to the mast arms. These tube holders cause additional weight, which must be taken into account when designing concrete distributor masts.
- DE 22 05 922 A1 discloses a concrete placing boom according to the preamble of claim 1.
- the object of the invention is to provide a concrete placing boom which has a good stability and torsional rigidity with a simultaneously low dead weight.
- a concrete placing boom according to claim 1 wherein at least one of the mast arms has a hollow chamber profile which has at least two mutually separated by a partition elongated hollow chambers, of which at least one closed and one is circumferentially open, and wherein the pipe segment associated with the respective mast arm is disposed on the opening side outside, partly inside or inside the open hollow chamber.

- An idea of the invention is also that a closed profile offers the advantage that the mast arm can be painted with little effort and rust problems are avoided due to penetrating water.
- a designed as a box mast arm can be made especially cranked with low production effort, d. H. to its sides simply or even angled several times. In a concrete placing boom, this offset is required on certain boom arms so that they can be moved past each other during operation.
- the concrete conveyor line accommodated on a mast arm and the angled design of the mast arms mean that the mast arms in a concrete placing mast are subjected to considerable torsional moments. These torsional moments are high in conventional concrete boom also because the boom construction of the tube holder increases these moments.
- An idea of the invention is therefore to adapt the cross section of the mast arms in a concrete placing boom to the local load of a mast arm. According to the invention it is therefore proposed to engage at least one of the side walls in a box-shaped mast arm for a concrete placing boom. Thus, a circumferentially open cavity is created as an additional space for the concrete delivery line, so that the concrete delivery line can be performed closer to the mast arm. With these measures In particular, it is possible to reduce the lever forces with which the load of the concrete delivery line acts via the tube holders on a mast arm.
- the mast arm having the hollow section profile is designed as a box with a top chord and a bottom chord having a first side wall which is engaged relative to the top chord and the bottom chord and which has a second side wall spaced from the first side wall, wherein the upper belt and the lower belt with the first side wall and the second side wall define the at least one closed hollow chamber, and the first side wall with the upper belt and the lower belt form the circumferentially open hollow chamber.

Description
Die Erfindung betrifft einen Betonverteilermast für stationäre und mobile Betonpumpen mit mehreren an Knickgelenken miteinander verbundenen Mastarmen und einer aus mehreren, vorzugsweise über Rohrbögen und Drehkupplungen gelenkig miteinander verbundenen, entlang den einzelnen Mastarmen geführten und an diesen befestigten Rohrsegmenten bestehenden Betonförderleitung.The invention relates to a concrete distribution mast for stationary and mobile concrete pumps with a plurality of articulated joints connected to articulated joints and a plurality of, preferably via pipe bends and rotary joints articulated interconnected, guided along the individual mast arms and attached to these pipe segments existing concrete delivery line.
Bekannte Betonverteilermasten haben Mastarme, die mit einem geschlossenen Kasten- oder Rohrprofil gestaltet sind (
Diese Aufgabe wird durch einen Betonverteilermast nach Anspruch 1 gelöst, bei dem mindestens einer der Mastarme ein Hohlkammerprofil aufweist, das mindestens zwei durch eine Trennwand voneinander getrennte langgestreckte Hohlkammern hat, von denen mindestens eine geschlossen und eine umfänglich offen ist, und wobei das dem betreffenden Mastarm zugeordnete Rohrsegment auf der Öffnungsseite außerhalb, teilweise innerhalb oder ganz innerhalb der offenen Hohlkammer angeordnet ist.This object is achieved by a concrete placing boom according to
Der Erfindung liegt der Gedanke zugrunde, dass ein Mastarm, der ein Kastenprofil hat, d. h. der einen Rechteckquerschnitt aufweist, unter fertigungstechnischen Gesichtspunkten durch Zusammenfügen von Gurtblechen und Seitenwand- bzw. Stegblechen mit einer sehr hohen Stabilität kostengünstig hergestellt werden kann, indem die betreffenden Bleche verschweißt werden. Ein Gedanke der Erfindung ist auch, dass ein geschlossenes Profil den Vorteil bietet, dass der Mastarm mit lediglich geringem Aufwand lackiert werden kann und Rostprobleme aufgrund von eindringendem Wasser vermieden werden. Ein als Kasten gestalteter Mastarm kann mit geringem fertigungstechnischem Aufwand auch insbesondere gekröpft gestaltet, d. h. zu seinen Seiten hin einfach oder auch mehrfach abgewinkelt werden. Bei einem Betonverteilermast ist diese Kröpfung bei bestimmten Mastarmen erforderlich, damit sie im Betrieb aneinander vorbei bewegt werden können.The invention is based on the idea that a mast arm, which has a box profile, d. H. having a rectangular cross-section, can be produced inexpensively from a technical point of view by joining belt plates and side wall or web plates with a very high stability by the respective sheets are welded. An idea of the invention is also that a closed profile offers the advantage that the mast arm can be painted with little effort and rust problems are avoided due to penetrating water. A designed as a box mast arm can be made especially cranked with low production effort, d. H. to its sides simply or even angled several times. In a concrete placing boom, this offset is required on certain boom arms so that they can be moved past each other during operation.
Die an einem Mastarm aufgenommene Betonförderleitung und die abgewinkelte Bauform von Mastarmen hat zur Folge, dass die Mastarme in einem Betonverteilermast erheblichen Torsionsmomenten ausgesetzt sind. Diese Torsionsmomente sind in herkömmlichen Betonverteilermasten auch deshalb hoch, weil die Auslegerkonstruktion der Rohrhalter diese Momente vergrößert.The concrete conveyor line accommodated on a mast arm and the angled design of the mast arms mean that the mast arms in a concrete placing mast are subjected to considerable torsional moments. These torsional moments are high in conventional concrete boom also because the boom construction of the tube holder increases these moments.
Eine Idee der Erfindung ist es deshalb, den Querschnitt der Mastarme in einem Betonverteilermast an die lokale Belastung eines Mastarms anzupassen. Erfindungsgemäß wird deshalb vorgeschlagen, bei einem kastenförmig gestalteten Mastarm für einen Betonverteilermast zumindest eine der Seitenwände einzurücken. Damit wird für die Betonförderleitung ein umfänglich offener Hohlraum als zusätzlicher Bauraum geschaffen, so dass die Betonförderleitung enger an dem Mastarm geführt werden kann. Mit diesen Maßnahmen lassen sich insbesondere die Hebelkräfte verringern, mit denen die Last der Betonförderleitung über die Rohrhalter an einem Mastarm angreift.An idea of the invention is therefore to adapt the cross section of the mast arms in a concrete placing boom to the local load of a mast arm. According to the invention it is therefore proposed to engage at least one of the side walls in a box-shaped mast arm for a concrete placing boom. Thus, a circumferentially open cavity is created as an additional space for the concrete delivery line, so that the concrete delivery line can be performed closer to the mast arm. With these measures In particular, it is possible to reduce the lever forces with which the load of the concrete delivery line acts via the tube holders on a mast arm.
Im Rahmen der Erfindung wird vorgeschlagen, dass der das Hohlkammerprofil aufweisende Mastarm als ein Kasten mit einem Obergurt und einem Untergurt gestaltet ist, der eine erste, gegenüber dem Obergurt und dem Untergurt eingerückte Seitenwand hat und der eine von der ersten Seitenwand beabstandete zweite Seitenwand aufweist, wobei der Obergurt und der Untergurt mit der ersten Seitenwand und der zweiten Seitenwand die mindestens eine geschlossene Hohlkammer definieren und die erste Seitenwand mit dem Obergurt und dem Untergurt die umfänglich offene Hohlkammer bilden. Diese umfänglich offene Hohlkammer kann z. B. einen trapezförmigen, insbesondere rechteckförmigen aber auch einen dreiecksförmigen Querschnitt haben.In the context of the invention, it is proposed that the mast arm having the hollow section profile is designed as a box with a top chord and a bottom chord having a first side wall which is engaged relative to the top chord and the bottom chord and which has a second side wall spaced from the first side wall, wherein the upper belt and the lower belt with the first side wall and the second side wall define the at least one closed hollow chamber, and the first side wall with the upper belt and the lower belt form the circumferentially open hollow chamber. This circumferentially open hollow chamber can, for. B. have a trapezoidal, in particular rectangular but also a triangular cross-section.
Auch die zweite Seitenwand kann gegenüber dem Obergurt und dem Untergurt eingerückt angeordnet sein und damit eine weitere umfängliche Hohlkammer definieren. Auch der Querschnitt dieser weiteren umfänglich offenen Hohlkammer kann trapezförmig, insbesondere rechteckförmig aber auch dreiecksförmig sein. Der Obergurt und der Untergurt sind bevorzugt zueinander parallel. Die erste Seitenwand und/oder die zweite Seitenwand steht dabei zu dem Obergurt und/oder dem Untergurt senkrecht. Um den Torsionsbelastungsverlauf in einem Mastarm zu optimieren, ist es von Vorteil, wenn der Abstand der ersten Seitenwand von der zweiten Seitenwand über den Mastarm hinweg variiert wird.Also, the second side wall may be arranged indented relative to the upper flange and the lower flange and thus define a further circumferential hollow chamber. The cross section of this further circumferentially open hollow chamber may be trapezoidal, in particular rectangular but also triangular. The upper belt and the lower belt are preferably parallel to each other. The first side wall and / or the second side wall is perpendicular to the upper belt and / or the lower belt. In order to optimize the torsional load curve in a mast arm, it is advantageous if the distance of the first side wall from the second side wall is varied over the mast arm.
Der Obergurt und/oder der Untergurt bei einem erfindungsgemäßen Mastarm kann auch über die Seitenwand eines Mastarms in unterschiedlichen Bereichen verschieden weit überstehen, d. h. der Obergurt und/oder der Untergurt kann eine Gurtkante haben, die von der ersten Seitenwand und/oder der zweiten Seitenwand in der Längsrichtung des Mastarms unterschiedliche Abstände hat.The top flange and / or the bottom flange in a mast arm according to the invention can also protrude differently over the side wall of a mast arm in different areas, ie the top chord and / or the bottom chord can have a belt edge extending from the first side wall and / or the second side wall the longitudinal direction of the mast arm has different distances.
Die erste Seitenwand und/oder die zweite Seitenwand kann eine an den Obergurt und/oder den Untergurt vormontierbare Anschlusspartie aufweisen. Mit der vormontierbaren Anschlusspartie lässt sich erreichen, dass die Seitenwand mit einer Anschlusskonstruktion versehen werden kann, die sich mit dem weiteren Mastarmabschnitten verschrauben lässt.The first side wall and / or the second side wall may have a connection part which can be preassembled on the upper belt and / or the lower belt. With the pre-mountable connection section, it is possible to provide the side wall with a connection construction which can be screwed to the other mast arm sections.
Eine Reduzierung der Torsionsbelastung eines mit einer Kröpfung versehenen Mastarms lässt sich insbesondere erreichen, wenn die Betonförderleitung in dem gekröpften Abschnitt von einer Seite des Mastarms durch die erste Seitenwand und durch die zweite Seitenwand zu der gegenüberliegenden Seite des Mastarms hindurchgeführt ist.A reduction in torsional loading of a cranked boom can be achieved, in particular, when the concrete conveyor line in the cranked section is passed from one side of the boom through the first sidewall and through the second sidewall to the opposite side of the boom.
Die Betonförderleitung ist dabei mit einem oder mehreren Rohrhaltern an der ersten Seitenwand oder der zweiten Seitenwand festgelegt und kann teilweise innerhalb oder ganz innerhalb der offenen Hohlkammer angeordnet sein.The concrete delivery line is fixed with one or more tube holders on the first side wall or the second side wall and may be partially disposed within or within the open hollow chamber.
Ein Mastarm mit einem Hohlkammerprofil kann zumindest teilweise aus faserverstärktem Kunststoff (Faserverbundkunstoff) oder aus Metall bestehen.A mast arm with a hollow chamber profile may at least partially made of fiber-reinforced plastic (fiber composite plastic) or made of metal.
Im Folgenden wird die Erfindung anhand eines in der Zeichnung in schematischer Weise dargestellten Ausführungsbeispiels näher erläutert.In the following the invention will be explained in more detail with reference to an embodiment shown schematically in the drawing.
