Description
Die Erfindung betrifft eine Autobetonpumpe mit wenigstens einem Teleskopschwenkbein und wenigstens einem Rahmenabschnitt, wobei das Teleskopschwenkbein wenigstens einen Schwenkabschnitt und wenigstens einen Teleskopabschnitt umfasst, wobei der Schwenkabschnitt schwenkbar an dem Rahmenabschnitt angelenkt ist und wobei wenigstens eine Energieführungseinrichtung vorgesehen ist, die dazu eingerichtet ist, wenigstens eine Abstützvorrichtung des Teleskopschwenkbeins mit Energie zu versorgen.The invention relates to a truck-mounted concrete pump with at least one telescopic pivot leg and at least one frame section, wherein the telescopic pivot leg comprises at least one pivoting section and at least one telescopic section, wherein the pivoting section is pivotally hinged to the frame section and wherein at least one energy guiding device is provided which is adapted to at least one Support device of the telescopic pivot leg to provide energy.
Teleskopschwenkbeine sind Teile der Tragstruktur von Autobetonpumpen und leiten die Lasten des Verteilermasts sowie gegebenenfalls weitere auf die Autobetonpumpe wirkende Lasten in den Untergrund der Autobetonpumpe ab. Die abgeleiteten Lasten können sich aus dem Eigengewicht des Verteilermasts, der Betonlast und aus dem Lastmoment der Gesamtmaschine ergeben.Telescopic swivel legs are part of the support structure of truck-mounted concrete pumps and discharge the loads of the distributor boom and, if necessary, other loads acting on the truck-mounted concrete pump into the subsoil of the truck-mounted concrete pump. The derived loads can result from the weight of the distributor boom, the concrete load and the load torque of the entire machine.
Zu diesem Zweck sind die Teleskopschwenkbeine an einen ihrer Enden mit einem sogenannten Mastbock verbunden, der als Rahmenabschnitt bezeichnet werden kann, welcher als Trägerelement des Verteilermasts funktioniert. Am anderen, äußeren Ende des Teleskopschwenkbeins befindet sich eine Abstützvorrichtung, zu deren Betrieb eine Energieführungseinrichtung vorgesehen sein kann. Die Energieführungseinrichtung kann wenigstens eine Elektroleitung bzw. ein Kabel, wenigstens eine Druckfluidleitung und/oder wenigstens eine Datenleitung zu einem Sensor und/oder zu einem Beleuchtungselement umfassen. Die Abstützvorrichtung kann einen Hydraulikzylinder, einen Spindelantrieb und/oder sonstige Antriebskomponenten umfassen.For this purpose, the telescopic pivot legs are connected at one of their ends with a so-called mast block, which can be referred to as a frame section, which functions as a support element of the distribution boom. At the other, outer end of the telescopic pivot leg is a support device, the operation of a power management device may be provided. The energy management device can comprise at least one electric line or a cable, at least one pressure fluid line and / or at least one data line to a sensor and / or to a lighting element. The support device may comprise a hydraulic cylinder, a spindle drive and / or other drive components.
Die Energieführungseinrichtung kann wenigstens eine Elektroleitung und/oder wenigstens eine Hydraulikleitung umfassen, die von einem Hydrauliktank bzw. einer Energieversorgungseinrichtung im Bereich des Mastbocks kommend durch das Teleskopschwenkbein beziehungsweise entlang des Teleskopschwenkbeins geführt sind. Die Energieführungseinrichtung dient dabei der Energiezuführung zur Abstützvorrichtung.The energy guiding device may comprise at least one electric line and / or at least one hydraulic line, which are guided by a hydraulic tank or a power supply device in the region of the mast block through the telescopic pivot leg or along the telescopic pivot leg. The energy guiding device serves to supply energy to the supporting device.
Eine Schwierigkeit bei aus dem Stand der Technik bekannten Autobetonpumpen besteht darin, dass Teleskopschwenkbeine zum einem eine vertikale Schwenkachse im Bereich der Anbindung an den Mastbock aufweisen und zum anderen ein- oder mehrfach teleskopierbar sind. Die Energieführungseinrichtung zur Versorgung der Abstützvorrichtung muss diesen Bewegungsfreiheitsgraden des Teleskopschwenkbeins folgen können.A difficulty with known from the prior art truck-mounted concrete pumps is that telescopic pivot legs for a have a vertical pivot axis in the region of the connection to the mast block and on the other hand one or several times telescoping. The energy management device for supplying the support device must be able to follow this degree of freedom of movement of the telescopic pivot leg.
Üblicherweise strebt man im Betonpumpenbau danach, Strukturen bzw. Tragstrukturen mit möglichst kleinen Abmaßen und einer insgesamt leichten Bauweise zu erreichen, um Maschinengewicht zu sparen und zulassungsrelevante Vorgaben zu erfüllen. Der Raum, der für die Energieführung im Teleskopschwenkbein zu Verfügung steht ist unter anderem deswegen sehr begrenzt und üblicherweise eher hoch als breit.Usually, in concrete pump construction, it is desired to achieve structures or supporting structures with as small dimensions as possible and an overall lightweight construction, in order to save machine weight and meet approval-relevant requirements. The space that is available for the energy guide in the telescopic swivel leg is therefore very limited and usually rather high than wide.
Bei bekannten Autobetonpumpen wird im Zusammenhang mit der Energieführung zur Abstützvorrichtung ein zweiteiliger Ansatz verfolgt: Die Schwenkbewegung des Teleskopschwenkbeins wird üblicherweise über biegsame Schläuche oder Kabel ausgeglichen, während die Teleskopierbarkeit des Teleskopschwenkbeins durch Nutzung einer waagrecht und damit breit verbauten Energieführungskette im Raum zwischen dem Beinkasten und dem Teleskopbein ausgeglichen wird.In known truck-mounted concrete pumps, a two-part approach is pursued in connection with the power supply to the outrigger: The pivotal movement of the telescopic pivot leg is usually compensated by flexible hoses or cables, while the telescoping of Teleskopschwenkbeins by using a horizontally and thus widely installed energy chain in the space between the leg box and the Telescopic leg is compensated.
Waagrecht eingebaut bedeutet dabei, dass die Gelenkachse der Energieführungskette beziehungsweise der Energieführungseinrichtung relativ zur Maschine waagrecht eingebaut ist. Die Energieführungskette kann also einen Radius in der senkrechten Ebene ausbilden.Installed horizontally means that the joint axis of the energy supply chain or the energy management device is installed horizontally relative to the machine. The energy chain can thus form a radius in the vertical plane.
Für die Unterbringung der Energieführungskette wird dabei abhängig von den mitgeführten bzw. in der Energieführungskette enthaltenen Schläuchen oder Kabeln vergleichsweise viel Raum benötigt.For the accommodation of the energy chain is thereby dependent on the entrained or contained in the energy supply chain hoses or cables comparatively much space needed.
Bei den aus dem Stand der Technik bekannten Betonpumpen kann das ausgleichen der Schwenkbewegung des Teleskopschwenkbeins mit ungeführten Schläuchen unerwünschte Biegungen und/oder Knickungen und damit vorzeitige Alterungen beziehungsweise Beschädigungen der Schläuche bewirken. Zudem zeichnet sich eine solche mehrteilige Lösung durch vergleichsweise viele auch unterschiedliche Teile und damit recht hohe Anschaffungs- und/oder Montagekosten aus. Andere Lösungen sind bislang nicht bekannt.In the known from the prior art concrete pumps balancing the pivoting movement of the telescopic pivot leg with unguided hoses cause undesirable bends and / or buckling and thus premature aging or damage to the hoses. In addition, such a multi-part solution is characterized by comparatively many different parts and thus quite high acquisition and / or installation costs. Other solutions are not known yet.
Vor diesem Hintergrund ist es Aufgabe der Erfindung, eine verbesserte Autobetonpumpe bereitzustellen, bei der insbesondere die Energieführungseinrichtung einfacher ausgeführt ist.Against this background, it is the object of the invention to provide an improved truck-mounted concrete pump in which, in particular, the energy-conducting device is made simpler.
Diese Aufgabe wird erfindungsgemäß von einer Autobetonpumpe mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved by a truck-mounted concrete pump with the features of
Demnach ist eine Autobetonpumpe mit wenigstens einem Teleskopschwenkbein und wenigstens einem Rahmenabschnitt vorgesehen, wobei das Teleskopschwenkbein wenigstens einen Schwenkabschnitt und wenigstens einen Teleskopabschnitt umfasst. Denkbar ist hierbei selbstverständlich auch, dass zwei oder mehr Teleskopabschnitte Teil eines entsprechenden Teleskopschwenkbeins sind.Accordingly, a truck-mounted concrete pump with at least one telescopic pivot leg and at least one frame section is provided, wherein the telescopic pivot leg comprises at least one pivoting section and at least one telescopic section. Of course, it is also conceivable that two or more telescopic sections are part of a corresponding telescopic pivot leg.
Erfindungsgemäß ist ferner vorgesehen, dass der Schwenkabschnitt schwenkbar an dem Rahmenabschnitt angelenkt ist und dass wenigstens eine Energieführungseinrichtung vorgesehen ist, die dazu eingerichtet ist, wenigstens eine Abstützvorrichtung des Teleskopschwenkbeins mit Energie zu versorgen. Die Energieführungseinrichtung kann hierbei beispielsweise Hydraulikleitungen umfassen, mittels derer Druckfluid zur Abstützvorrichtung und entlang des Teleskopschwenkbeins zugeführt werden kann.According to the invention it is further provided that the pivot portion is pivotally hinged to the frame portion and that at least one energy guiding device is provided which is adapted to provide at least one supporting device of the telescopic pivot leg with energy. In this case, the energy guiding device may include, for example, hydraulic lines, by means of which pressurized fluid can be supplied to the supporting device and along the telescopic pivot leg.
Erfindungsgemäß ist des Weiteren vorgesehen, dass die Energieführungseinrichtung wenigstens eine parallel zur Schwenkachse des Schwenkabschnitts angeordnete Schwenkachse aufweist, um die die Energieführungseinrichtung schwenkbar ist.According to the invention, it is further provided that the energy guiding device has at least one pivot axis arranged parallel to the pivot axis of the pivoting section about which the energy guiding device is pivotable.
Die erfindungsgemäße Idee besteht somit darin, die Beweglichkeit von Energieführungsketten beziehungsweise Energieführungseinrichtungen in einer Ebene durch Drehung um 90° dahingehend zu nutzen, dass eine einzige Energieführungskette sowohl die Schwenkbewegung als auch das Teleskopieren eines Teleskopschwenkbeins ausgleicht.The idea according to the invention therefore consists in utilizing the mobility of energy guiding chains or energy guiding devices in a plane by rotation through 90 ° in such a way that a single energy guiding chain compensates for both the pivoting movement and the telescoping of a telescopic pivoting leg.
Durch Drehen der Gelenksachse der Energieführungseinrichtung in die Senkrechte relativ zur Maschine beziehungsweise parallel zur Schwenkachse des Teleskopschwenkbeins folgt die Energieführungseinrichtung bzw. die Energieführungskette beiden Bewegungen. Bei geschickter Ausführung der Energieführungseinrichtung mit breiten Kettengliedern kann diese im Idealfall auch ohne weitere Führung und ohne weitere Trägerelemente ausgeführt sein.By rotating the joint axis of the energy guiding device in the vertical direction relative to the machine or parallel to the pivot axis of the telescopic pivot leg, the energy guiding device or the energy guiding chain follows both movements. With skillful execution of energy management device with wide chain links this can be carried out in the ideal case without further guidance and without further support elements.
Die Energieführungseinrichtung übernimmt im Abwicklungsbereich dabei selbst die Schlauch-/Kabelführung. Bisher mussten hierfür separate Befestigungen vorgesehen werden, welche eine entsprechende Verformung zulassen. Erfindungsgemäß ist eine bessere Führung möglich und die geführten Kabel/Schläuche sind zudem besser geschützt. Damit wird auch eine kompaktere Ausführung der Energieführungseinrichtung ermöglicht. Diese kann demnach eine geringere Breiten- und/oder Höhenerstreckung aufweisen. Hierdurch wird es wiederum ermöglicht, den Teleskopquerschnitt des Teleskopschwenkbeins breiter auszuführen, was eine bessere statische Auslegung ermöglicht.The energy management device itself takes over the hose / cable management in the processing area. So far, separate fasteners had to be provided for this purpose, which allow a corresponding deformation. According to the invention, a better guidance is possible and the guided cables / hoses are also better protected. This also enables a more compact design of the energy-conducting device. This can therefore have a smaller width and / or height extension. This makes it possible, in turn, the telescopic cross-section the telescopic pivot leg wider, which allows a better static design.
Die erfindungsgemäße Ausführung der Autobetonpumpe zeichnet sich damit durch ein besonders hohes Maß an Einfachheit ohne Abstriche bei deren Funktionalität aus. Ferner decken sich die Abmaße von Energieführungseinrichtungen bei dieser Art von Neuorientierung ideal mit den zur Verfügung stehenden Bauräumen im Teleskopschwenkbein.The inventive design of the truck-mounted concrete pump is characterized by a particularly high degree of simplicity without sacrificing their functionality. Furthermore, the dimensions of energy management devices in this type of reorientation ideally coincide with the available installation space in the telescopic pivot leg.
In einer bevorzugten Ausführung der Erfindung ist denkbar, dass die Energieführungseinrichtung eine Energieführungskette ist. Diese kann in bekannter Weise Hohlräume und/oder Aussparungen aufweisen, innerhalb derer energieführende Elemente als Energieführungseinrichtungen wie beispielsweise Elektroleitungen, Druckluftleitungen und/oder Hydraulikleitungen der Energieführungskette angeordnet, geführt und/oder geschützt sind.In a preferred embodiment of the invention, it is conceivable that the energy guiding device is an energy guiding chain. This may have cavities and / or recesses in a known manner, within which energy-conducting elements are arranged, guided and / or protected as energy-conducting devices such as, for example, electric lines, compressed-air lines and / or hydraulic lines of the energy-carrying chain.
In einer weiteren bevorzugten Ausführung ist denkbar, dass sich die Energieführungseinrichtung in einem eingeschwenkten und/oder einteleskopierten Zustand des Teleskopschwenkbeins nach weiter hinten oder nach weiter vorne bezogen auf die Autobetonpumpe erstreckt als das Teleskopschwenkbein. Je nachdem ob es sich um ein vorderes oder um ein hinteres Teleskopschwenkbein handelt kann somit die Erstreckung bzw. Positionierung der Energieführungseinrichtung so gewählt werden, dass die Bewegungsfreiheit des Teleskopschwenkbeins möglichst einfach groß gehalten wird. Im Falle eines einzelnen oder vorderen Teleskopschwenkbeins kann sich die Energieführungseinrichtung nach weiter hinten und im Falle eines hinteren Teleskopschwenkbeins nach weiter vorne erstrecken.In a further preferred embodiment, it is conceivable that the energy guiding device extends in a pivoted-in and / or telescoping state of the telescopic pivot leg towards farther back or farther forward with respect to the truck-mounted concrete pump than the telescopic pivot leg. Depending on whether it is a front or a rear telescopic pivot leg, the extension or positioning of the energy guiding device can thus be selected such that the freedom of movement of the telescopic pivot leg is kept as large as possible. In the case of a single or front telescopic pivot leg, the energy guiding device may extend farther back and, in the case of a rear telescopic pivot leg, further forward.
Der eingeschwenkte Zustand des Teleskopschwenkbeins meint vorliegend einen Zustand, in welchem das Teleskopschwenkbein im Wesentlichen parallel zur Längsachse der Autobetonpumpe und üblicherweise zum Verfahren und nicht zum Abstützen der Autobetonpumpe positioniert ist.The pivoted state of the telescopic pivot leg means in the present case a state in which the telescopic pivot leg is positioned substantially parallel to the longitudinal axis of the truck-mounted concrete pump and usually for the method and not for supporting the truck-mounted concrete pump.
Der einteleskopierte Zustand des Teleskopschwenkbeins meint der Wortbedeutung folgend einen Zustand, in welchem der Teleskopabschnitt des Teleskopschwenkbeins in einem einteleskopierten Zustand, das heißt in einem Zustand ist, in welchem das Teleskopschwenkbein eine geringe beziehungsweise seine geringste Längserstreckung aufweist.The einteleskopierte state of the telescopic pivot leg of the word meaning following a state in which the telescopic portion of the telescopic pivot leg in a einteleskopierten state, that is in a state in which the telescopic pivot leg has a small or its smallest longitudinal extent.
In einer weiteren bevorzugten Ausführung ist denkbar, dass sich die Energieführungseinrichtung in einem ausgeschwenkten und/oder austeleskopierten Zustand des Teleskopschwenkbeins nach weiter innen bezogen auf die Autobetonpumpe erstreckt als das Teleskopschwenkbein. Hierbei kann insbesondere vorgesehen sein, dass eine als Energieführungskette ausgebildete Energieführungseinrichtung wenigstens teilweise weiter innen und/oder weiter hinten als das Teleskopschwenkbein angeordnet ist.In a further preferred embodiment, it is conceivable that the energy guiding device extends in a swiveled and / or telescoped state of the telescopic pivot leg to further inside relative to the truck-mounted concrete pump as the telescopic pivot leg. In this case, provision can be made, in particular, for an energy guiding device designed as an energy guiding chain to be arranged at least partially further inwards and / or farther back than the telescopic pivoting leg.
Durch die Nutzung des bezogen auf das Teleskopschwenkbein weiter innen und/oder weiter hinten liegenden Bauraums der Autobetonpumpe, kann die Energieführungseinrichtung besonders einfach dazu angeordnet werden, die Bewegungsfreiheit des Teleskopschwenkbeins nicht zu begrenzen.By using the relative to the telescopic pivot leg further inside and / or further back space of the truck-mounted concrete pump, the energy management device can be particularly easily arranged to not limit the freedom of movement of the telescopic pivot leg.
Der ausgeschwenkte Zustand des Teleskopschwenkbeins ist ein Zustand, bei dem das Teleskopschwenkbein nicht parallel zur Betonpumpe angeordnet ist, beziehungsweise zum Abstützen in einem Arbeitszustand der Autobetonpumpe angewinkelt zu dieser ist. Der austeleskopierte Zustand des Teleskopschwenkbeins entspricht einem Zustand, in dem der Teleskopabschnitt und der Rahmenabschnitt des Teleskopschwenkbeins so zueinander verstellt sind, dass das Teleskopschwenkbein ausgefahren beziehungsweise in einem Zustand größter beziehungsweise nicht geringster Länge ist.The pivoted state of the telescopic pivot leg is a state in which the telescopic pivot leg is not arranged parallel to the concrete pump, or is angled for supporting in a working state of the truck concrete pump to this. The telescoped state of the telescoping rocker leg corresponds to a state in which the telescoping section and the frame section of the telescoping rocker leg are adjusted relative to each other so that the telescoping rocker leg is extended or in a state of greatest or not least length.
In einer weiteren bevorzugten Ausführung ist denkbar, dass sich die Energieführungseinrichtung wenigstens teilweise innerhalb des Teleskopabschnitts erstreckt. Der Teleskopabschnitt selbst kann wenigstens abschnittsweise als Hohlprofilelement ausgebildet sein beziehungsweise ein Hohlprofil aufweisen, innerhalb dessen die Energieführungseinrichtung wenigstens teilweise angeordnet sein kann. Hierdurch kann die Energieführungseinrichtung durch die Wandungen des Teleskopabschnitts beispielsweise vor Beschädigungen und/oder Verschmutzungen geschützt sein.In a further preferred embodiment, it is conceivable that the energy guiding device extends at least partially within the telescope section. The telescopic section itself can be formed at least in sections as a hollow profile element or have a hollow profile, within which the energy guiding device can be arranged at least partially. hereby For example, the energy-conducting device can be protected by the walls of the telescopic section from damage and / or dirt.
In einer weiteren bevorzugten Ausführung ist denkbar, dass an dem Teleskopabschnitt wenigstens eine Ausnehmung und/oder wenigstens eine Durchführung zum Aufnehmen der Energieführungseinrichtung vorgesehen sind. Demnach kann der Teleskopabschnitt unterschiedliche Profilquerschnitte entlang seiner Längsachse aufweisen umso wenigstens abschnittsweise zur Aufnahme der Energieführungseinrichtung ausgebildet zu sein.In a further preferred embodiment, it is conceivable that at least one recess and / or at least one passage for receiving the energy guiding device are provided on the telescopic section. Accordingly, the telescopic section may have different profile cross-sections along its longitudinal axis so as to be formed at least in sections for receiving the energy-conducting device.
In einer weiteren bevorzugten Ausführung ist denkbar, dass die Energieführungseinrichtung eine einzelne bzw. durchgängige Verbindung des Rahmenabschnitts mit dem Teleskopabschnitt ist. Als einzelne bzw. durchgängige Verbindung ist dabei eine gleichartige Verbindung zu verstehen, welche also über die gesamte Verbindungslänge zwischen Rahmenabschnitt und Teleskopabschnitt bzw. Abstützvorrichtung gleichartig aufgebaut ist und deren einzelne Abschnitte sich von den jeweils anderen Abschnitten entlang der Länge der Verbindung nicht unterscheiden. Als durchgängig wird eine Verbindung verstanden, die von dem Rahmenabschnitt bis zum Teleskopabschnitt bzw. bis zur Abstützvorrichtung verläuft und diese Komponenten allein, das heißt ohne weitere, gegebenenfalls davon unterschiedliche Verbindungsabschnitte zur Energieübertragung miteinander verbindet.In a further preferred embodiment, it is conceivable that the energy guiding device is a single or continuous connection of the frame section to the telescope section. As a single or continuous connection is to be understood a similar connection, which is thus constructed over the entire connection length between the frame section and telescopic section or support device similar and their individual sections do not differ from the other sections along the length of the connection. As a continuous connection is understood, which extends from the frame portion to the telescopic section or to the support device and these components alone, that is, without further, possibly different connection sections for energy transfer from each other.
In einer weiteren bevorzugten Ausführung ist denkbar, dass die Energieführungseinrichtung den Teleskopabschnitt wenigstens teilweise umgreift. Dies kann insbesondere an einem Längsende des Teleskopabschnitts der Fall sein. Das Umgreifen bedeutet vorliegend, dass der Teleskopabschnitt wenigstens teilweise zwischen der Energieführungseinrichtung angeordnet ist.In a further preferred embodiment, it is conceivable that the energy guiding device at least partially surrounds the telescope section. This may be the case in particular at a longitudinal end of the telescope section. In the present case, encompassing means that the telescope section is arranged at least partially between the energy-conducting device.
In einer weiteren bevorzugten Ausführung ist denkbar, dass die Energieführungseinrichtung im Bereich der unteren oder der oberen Hälfte des Teleskopabschnitts angeordnet ist. Denkbar ist auch, dass die Energieführungseinrichtung mittig oder allgemein außermittig bezogen auf die Vertikale des Teleskopabschnitts angeordnet ist.In a further preferred embodiment, it is conceivable that the energy guiding device is arranged in the region of the lower or the upper half of the telescopic section. It is also conceivable that the energy management device in the middle or is arranged generally eccentrically relative to the vertical of the telescopic section.
Ferner ist denkbar, dass die Energieführungseinrichtung wenigstens teilweise an einer Außenseite des Teleskopabschnitts angeordnet ist, die auf die Autobetonpumpe hin oder von der Autobetonpumpe weg gerichtet ist und/oder dass wenigstens ein vorderes Teleskopschwenkbein und wenigstens ein hinteres Teleskopschwenkbein vorgesehen sind, die insbesondere über eine gemeinsame Schwenkachse relativ zum weiteren Gefüge der Autobetonpumpe verschwenkbar sind. Somit kann ein gemeinsamer Anlenkpunkt für den vorderen und hinteren Schwenkholm bzw. für das entsprechende Teleskopschwenkbein vorgesehen sein.It is also conceivable that the energy guiding device is at least partially disposed on an outer side of the telescopic section, which is directed towards the truck-mounted concrete pump or away from the truck-mounted concrete pump and / or that at least one front telescopic pivot leg and at least one rear telescopic pivot leg are provided, in particular via a common Pivot axis are pivotable relative to the further structure of the truck-mounted concrete pump. Thus, a common pivot point for the front and rear pivot spar or for the corresponding telescopic pivot leg can be provided.

Das Teleskopschwenkbein 1 beziehungsweise die Teleskopschwenkbeine 1 können schwenkbar an einem Rahmenabschnitt 4 angelenkt sein, wobei es sich bei dem Rahmenabschnitt 4 um einen Mastbock mit einem Tank beziehungsweise mit einer Energieversorgungseinrichtung handeln kann. Der Rahmenabschnitt 4 kann auch unterschiedlich vom Mastbock sein und/oder einen Rahmen 6a oder Rahmenteil beschreiben, die weiter hinten bezogen auf den Mastbock verortet ist. Die Energieversorgung kann dazu eingerichtet sein, eine Abstützvorrichtung 6 des Teleskopschwenkbeins 1 mit Energie bzw. elektrischem Strom und/oder Druckfluid zu versorgen.The
Das Teleskopschwenkbein 1 umfasst wenigstens einen Teleskopabschnitt 3, welcher teleskopierbar beziehungsweise verschieblich in einem Schwenkabschnitt 2 gelagert ist.

Das Teleskopschwenkbein 1 ist über wenigstens eine Energieführungseinrichtung 5 mit dem Rahmenabschnitt 4, dem Rahmen 6a und/oder mit sonstigen Abschnitten des weiteren Gefüges der Autobetonpumpe zur Energieübertragung gekoppelt.

Bei dem Verschwenken der Energieführungseinrichtung 5 kann es sich um eine andere Art des Verschwenkens handeln als bei dem Verschwenken des Schwenkabschnitts 2 des Teleskopschwenkbeins 1. Während das Schwenken des Schwenkabschnitts 2 um eine feste, durch die Position des Rahmenabschnitts 4 und des Schwenkabschnitts 2 definierte Schwenkachse erfolgt, kann die Schwenkachse der Energieführungseinrichtung 5 aufgrund der flexiblen Ausbildung der Energieführungseinrichtung 5 je nach Schwenkzustand unterschiedlich positioniert sein.The pivoting of the

Das Teleskopieren des Teleskopabschnitts 3 relativ zum Schwenkabschnitt 2 wird durch den Schlauch 51 allerdings nicht ermöglicht. Hierzu ist eine Energieführungskette 52 vorgesehen, die lediglich den Schwenkabschnitt 2 mit dem Teleskopabschnitt 3 verschieblich verbindet bzw. koppelt. Die aus dem Stand der Technik bekannte Energieführungskette 52 kann kürzer und anders orientiert sein, als die erfindungsgemäß vorgesehene Energieführungseinrichtung 5.Here, a
