Description

Die vorliegende Erfindung betrifft ein Fahrzeug zur Anlieferung und Aufbereitung von Trockenbaustoffen an die/der Baustelle und ein Transportfahrzeug zur Anlieferung eines Bindemittel/Zuschlagsgemischs.The present invention relates to a vehicle for the delivery and processing of dry building materials to / the construction site and a transport vehicle for the delivery of a binder / aggregate mixture.

Trockenbaustoffe, z.B. Betonmischungen werden bislang einbaufertig mittels Transportfahrzeugen an die Baustelle geliefert. Diese Transportfahrzeuge haben einen, oft als Mischtrommel ausgebildeten, Behälter, in dem ein Bindemittel, insbesondere Zement, und Gesteinskörnungen, wie z. B. Sand und dergleichen zusammen mit Wasser angemischt und einbaufertig an die Baustelle geliefert wird.Dry building materials, e.g. Concrete mixtures are delivered to the construction site so far ready for installation by means of transport vehicles. These transport vehicles have a, often designed as a mixing drum, container in which a binder, in particular cement, and aggregates, such. As sand and the like mixed with water and ready for installation is delivered to the site.

Dies ist in den Fällen problematisch, in welchen der Fahrweg des Transportfahrzeugs zum Einbauort aufgrund der örtlichen Bedingungen z. B. in einem Tunnel besonders lang ist und in Fällen, in denen nur kleine Chargen zur Verarbeitung benötigt werden. Im ersten Fall muss das einbaufertige Gemisch so eingestellt werden, dass es über den gesamten benötigten Zeitraum verarbeitbar ist und daher nicht bereits während der Fahrt abbindet. Doch muss dann bei der Verarbeitung durch die Zugabe von Beschleunigern sicher gestellt werden, dass die Betonmischung nach dem Aufbringen schnell abbindet. Da eine lange Verarbeitungszeit notwendig ist, muss relativ viel Beschleuniger zugesetzt werden, um diesen Anforderungen zu genügen.This is problematic in cases in which the path of the transport vehicle to the installation due to the local conditions such. B. is particularly long in a tunnel and in cases where only small batches are needed for processing. In the first case, the ready-to-install mixture must be adjusted so that it can be processed over the entire required period of time and therefore does not set during the journey. However, during processing, it must be ensured by the addition of accelerators that the concrete mix sets quickly after application. Since a long processing time is necessary, a relatively large amount of accelerator must be added to meet these requirements.

Im zweiten Fall, indem nur geringe Chargen benötigt werden, wie z. B. beim Erstellen von Türmen, z. B. für Windräder, wo der Beton chargenweise an die Turmspitze transportiert und verarbeitet wird, besteht der Nachteil darin, dass das Transportfahrzeug mit einem nur teilweise gefüllten Mischbehälter losfährt, was die Anlieferpreise für den Beton drastisch verteuert.In the second case, by only small batches are needed, such. B. when creating towers, z. As for wind turbines, where the concrete is transported in batches to the spire and processed, the disadvantage is that the transport vehicle losfährt with a partially filled mixing container, which drastically increases the delivery prices for the concrete.

Es ist Aufgabe der Erfindung, ein Transportfahrzeug zur Anlieferung und Aufbereitung von Trockenbaustoffen zu schaffen, das eine individuelle Verarbeitung mit geringen Beschleunigereinsatz unabhängig von der Dauer des Anfahrweges erlaubt. Diese Aufgabe wird durch ein Transportfahrzeug gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildung der Erfindung sind Gegenstand der zugehörigen Unteransprüche.It is an object of the invention to provide a transport vehicle for the delivery and processing of dry building materials, which allows individual processing with low accelerator use, regardless of the duration of the Anfahrweges. This task is through Transport vehicle solved according to claim 1. Advantageous development of the invention are the subject of the associated dependent claims.

Erfindungsgemäß weist das Transportfahrzeug neben dem Behälter, der ein geschlossener oder offener Behälter in Art einer Mischtrommel sein kann, eine Misch/Fördereinrichtung auf, in welcher das vorzugsweise trockene bzw. noch weit gehend trockene bzw. erdfeuchte Gemisch aus Bindemittel und Gesteinsmischungen bzw. Zuschlagsstoffen und Additiven mit Wasser vermischt und somit verarbeitungsfertig angemacht wird. Die Mischeinrichtung ist hierfür mit einem Wasseranschluss versehen bzw. mit einem Wassertank verbunden, der die einbaufertige Zubereitung des Trockenbaustoffs erlaubt. Der Rohrmischer kann selbstverständlich für die Zugabe von Additiven ausgebildet sein. Hierfür weist der Rohrmischer die erforderlichen Zugabeeinrichtungen bzw. Verbindungen mit Tank für Additiven auf. Der Rohrmischer nimmt das noch nicht angemachte Trockenbaustoffgemisch auf, vermengt es mit Wasser und gibt es z.B. an eine Betonpumpe oder eine Spritzanlage ab. Es ist selbstverständlich nach dem fertigen Anmischen in dem Rohrmischer auch jede andere, z.B. manuelle, Verarbeitung des einbaufertigen Gemischs, nachfolgend beispielsweise Betongemischs, denkbar. Da die Betonmischung erst am Einbauort in dem Rohrmischer angemacht wird, kann die Verarbeitungszeit des Betons drastisch reduziert werden, was verschiedene Vorteile mit sich bringt.According to the invention, the transport vehicle in addition to the container, which may be a closed or open container in the manner of a mixing drum, a mixing / conveyor, in which the preferably dry or dry or largely dry mixture of binder and rock mixtures or aggregates and additives Additives mixed with water and thus turned on ready for use. For this purpose, the mixing device is provided with a water connection or connected to a water tank, which allows the ready-to-dry preparation of the dry building material. The tube mixer can of course be designed for the addition of additives. For this purpose, the tube mixer on the required addition devices or compounds with tank for additives. The tube mixer picks up the unburned dry mortar mixture, mixes it with water and gives it e.g. to a concrete pump or sprayer. It is of course after the finished mixing in the tube mixer also any other, e.g. manual, processing the ready-mixed mixture, hereinafter, for example, concrete mix conceivable. Since the concrete mix is first turned on at the installation site in the tube mixer, the processing time of the concrete can be drastically reduced, which brings various benefits.

Ein Vorteil der Erfindung besteht darin, dass in dem Mischbehälter, d.h. der Mischtrommel des Transportfahrzeugs nur der Trockenbaustoff gemischt wird, wodurch die Bestandteile des Trockenbaustoffs wegen der Drehung der Mischtrommel optimal homogenisiert werden. Der fertig angemischte Baustoff nach dem Durchlaufen des Rohrmischers hat damit über die gesamte Ausgabezeit eine gleich bleibende homogene Qualität im Gegensatz zur Siloanlieferung von Trockenbaustoffen , wo aufgrund der Schwerkraft eine Entmischung auftritt und damit die Qualität des Baustoffes über den Abgabezeitraum schwankt.An advantage of the invention is that in the mixing vessel, i. the mixing drum of the transport vehicle only the dry building material is mixed, whereby the components of the dry building material are optimally homogenized because of the rotation of the mixing drum. The ready-mixed building material after passing through the pipe mixer has thus over the entire output time a consistent homogeneous quality in contrast to the silo delivery of dry building materials, where due to gravity segregation occurs and thus the quality of the building material fluctuates over the discharge period.

Selbstverständlich ist die Erfindung nicht nur auf Trockenbaustoffe, wie z.B. Trockenbeton bzw. auf die Anmischung von Fertigbeton beschränkt sondern erstreckt sich auf alle Arten von Baustoffen.Of course, the invention is not limited to dry building materials, e.g. Dry concrete or limited to the mixing of precast concrete but extends to all types of building materials.

Vorzugsweise sind mit dem Rohrmischer Dosiereinrichtungen für die Wasserzufuhr bzw. die Zufuhr der Additive verbunden.Preferably, metering devices for the supply of water or the supply of the additives are connected to the tube mixer.

Der Rohrmischer weist vorteilhafterweise eine Misch- und Förderschnecke auf, welche es erlaubt, das Trockenbaustoffgemisch bis zum Ort der Verwendung an die Verwendungsstelle abzugeben.The tube mixer advantageously has a mixing and conveying screw, which allows to deliver the dry mortar mixture to the place of use to the point of use.

Vorzugsweise ist zumindest ein Teil der Welle des Rohrmischers axial verschiebbar in dem Rohrmischer angeordnet. So ist es möglich, vor dem insbesondere seitlichen Verschwenken eines Teils des Rohrmischers, insbesondere des Förder- und Mischrohres die Welle im Förder- und Mischrohr von der Antriebswelle auf einfache Weise zu trennen. Die ist besonders dann vorteilhaft, wenn in einer vorteilhaften Ausgestaltung der Erfindung des Förder- und Mischrohr - insbesondere um eine vertikale Achse - verschwenkbar auf dem Transportfahrzeug gehalten ist. In diesem Fall kann nämlich das Förder- und Mischrohr in Transportstellung seitlich oder nach oben/unten weg geschwenkt werden, so dass es nicht nach hinten über das Fahrzeug hinaus steht.Preferably, at least a part of the shaft of the tube mixer is arranged axially displaceable in the tube mixer. Thus, it is possible to separate the shaft in the conveying and mixing tube of the drive shaft in a simple manner before the particular lateral pivoting of a portion of the pipe mixer, in particular the conveying and mixing tube. This is particularly advantageous if in an advantageous embodiment of the invention of the conveyor and mixing tube - in particular on a vertical axis - is pivotally supported on the transport vehicle. In this case, namely, the conveyor and mixing tube can be pivoted away in the transport position laterally or up / down, so that it does not stand backwards beyond the vehicle.

Nach der Abgabe der gewünschten Betoncharge bzw. nach Abschluss des kontinuierlichen Anlieferungsverfahrens wird der Rohrmischer gereinigt und ist somit für den nächsten Einsatz bzw. die Zubereitung der nächsten Charge bereit.After delivery of the desired concrete batch or after completion of the continuous delivery process, the tube mixer is cleaned and is thus ready for the next use or the preparation of the next batch.

Durch die Erfindung ist es auch möglich, kleinere Chargen an verschiedenen Baustellen abzuliefern, was wiederum die Anlieferungskosten für den Beton beträchtlich verringert.By the invention it is also possible to deliver smaller batches at different construction sites, which in turn considerably reduces the delivery costs for the concrete.

Verfahrensmäßig ist die Erfindung dadurch gekennzeichnet, dass die einbaufertige Zubereitung des Trockenbaustoffgemisches vor Ort, d. h. am Einsatzort erfolgt, wodurch das Vorhalten einer Verarbeitungszeit für den Anfahrweg entfällt und darüber hinaus eine Zubereitung nur eines Teiles des Behälterinhaltes des Transportfahrzeugs möglich ist. Eine derartige Mischeinrichtung muss dann nicht zwangsweise am Transportfahrzeug angeordnet sein, obwohl dies sehr vorteilhaft ist, sondern kann auch an der Baustelle selbst stehen.In terms of method, the invention is characterized in that the ready-to-install preparation of the dry building material mixture takes place on site, ie at the site, thereby eliminating the need for a processing time for the Anfahrweg and beyond a preparation of only a portion of the container contents of the transport vehicle is possible. Such a mixing device then need not necessarily be arranged on the transport vehicle, although this is very advantageous, but can also stand on the site itself.

In einer vorteilhaften Ausbildung kann auch vorgesehen sein, dass der Rohrmischer lösbar an dem Transportfahrzeug gehalten und für den Einsatz auf der Baustelle abstellbar ist. In diesem Fall muss der Rohrmischer gegebenenfalls über die notwendigen Dosiereinrichtungen und Wasseranschlüsse bzw. Anschlüsse für Additive verfügen, um eine Zubereitung des Trockenbaustoffs in Verbindung mit dem Transportfahrzeug oder auch autark davon zu ermöglichen.In an advantageous embodiment can also be provided that the pipe mixer is releasably held on the transport vehicle and can be turned off for use on the site. In this case, the pipe mixer may need to have the necessary metering devices and water connections or connections for additives to prepare the dry building material in connection with the transport vehicle or to make it self-sufficient.

Auch wenn es vorteilhaft ist, dass der Rohrmischer auf ein- und demselben Fahrzeug wie der Behälter selbst angeordnet ist, so können diese Komponenten auch getrennt auf einem Gespann angeordnet sein, wobei dann beispielsweise sowohl auf dem Zugfahrzeug als auch auf dem Anhänger jeweils ein Behälter und auf dem Zugfahrzeug oder dem Anhänger einen Rohrmischer angeordnet sein können. Es ist selbstverständlich möglich, mehrere Behälter als auch mehrere Mischeinrichtungen auf dem Transportfahrzeug anzuordnen.Although it is advantageous that the tube mixer is arranged on one and the same vehicle as the container itself, so these components can also be arranged separately on a trailer, in which case, for example, both on the towing vehicle and on the trailer one container and on the towing vehicle or trailer a pipe mixer can be arranged. It is of course possible to arrange a plurality of containers as well as a plurality of mixing devices on the transport vehicle.

Darüber hinaus bedarf es keiner Erläuterung, dass neben dem Rohrmischer alle notwendigen Pumpen und Dosiereinrichtungen vorzugsweise ebenfalls auf dem Transportfahrzeug angeordnet sind.In addition, there is no need to explain that in addition to the pipe mixer all the necessary pumps and metering devices are preferably also arranged on the transport vehicle.

Die Erfindung wird nachfolgend beispielsweise anhand der schematischen Zeichnung beschrieben. In dieser zeigen:

Der Fahrmischer 10 hat ein Chassis 12, auf dem ein Behälter für einen Trockenbaustoff in Form einer Mischtrommel 14 drehbar angetrieben gehalten ist. Der Antrieb 16 der Mischtrommel 14 befindet sich an ihrer Vorderseite. An der Rückseite der Mischtrommel 14 ist das Zugabe- bzw. Auslassende 18 angeordnet. Unter diesem Auslassende 18 ist ein Rohrmischer 20 - vorzugsweise lösbar - gehalten. Der Rohrmischer 20 ist ausgebildet für die Aufbereitung eines in der Mischtrommel 14 an die Baustelle angelieferten Trockenbetongemischs mit Wasser und Additiven. Hierfür ist der Rohrmischer 20 mit an sich bekannten Mischorganen versehen. Das Aufbereiten des in der Mischtrommel 14 befindlichen Trockengemisches erfolgt an der Baustelle entweder kontinuierlich oder chargenweise. Hierfür weist das Transportfahrzeug vorzugsweise einen Wassertank 22 auf, welcher mit dem Rohrmischer 20 verbunden ist. Das Wasser kann jedoch auch an der Baustelle vorgehalten werden. Für die Betätigung des Rohrmischers 20 ist eine Steuerung vorgesehen, über den sich der Rohrmischer 20 selbst betätigen lässt als auch die notwendigen Dosier bzw. Zufuhreinrichtungen für Wasser und Additive. Die hierfür vorzusehenden Leitungen und Pumpen sind in der Zeichnung nicht dargestellt, ebenso wie gegebenenfalls vorzusehende Tanks für Additive, die beim gebrauchsfertigen Aufbereiten der Betonmischung mit zugegeben werden.The truck mixer 10 has a chassis 12 on which a container for a dry building material in the form of a mixing drum 14 is rotatably driven. The drive 16 of the mixing drum 14 is located at its front. At the rear of the mixing drum 14, the addition or outlet end 18 is arranged. Under this outlet end 18, a pipe mixer 20 - preferably releasably - held. The pipe mixer 20 is designed for the treatment of a delivered in the mixing drum 14 to the site dry concrete mixture with water and additives. For this purpose, the tube mixer 20 is provided with known mixing elements. The processing of the present in the mixing drum 14 dry mixture takes place at the site either continuously or batchwise. For this purpose, the transport vehicle preferably has a water tank 22, which is connected to the pipe mixer 20. However, the water can also be kept at the construction site. For the operation of the pipe mixer 20, a control is provided, over which the pipe mixer 20 operate itself as well as the necessary dosing or supply facilities for water and additives. The purpose to be provided lines and pumps are not shown in the drawing, as well as possibly to be provided tanks for additives that are added in the ready-to-use treatment of the concrete mix with.

Ein wesentlicher Aspekt der Erfindung besteht darin, dass das vom Transportfahrzeug angelieferte Bindemittel/Zuschlaggemisch noch nicht abbindefertig ist, weshalb es beliebig lange transportiert werden kann, ohne dass die Verarbeitungsqualität des Gemischs durch zwischenzeitliches Abbinden während des Transports beeinträchtigt worden ist. Zudem ist an der Baustelle dder Trockenbaustoff ideal homogenisiert, so dass eine gleich bleibend hohe Qualität des verarbeitungsfertigen Baustoffes über den gesamten Abgabezeitraum gewährleistet ist. Weiterhin kann die Mischung besser auf die Verarbeitungsbedürfnisse an der Baustelle abgestellt werden. Vorzugsweise ist an dem Transportfahrzeug auch ein Behälter und eine Zudosiereinrichtung für den Beschleuniger vorgesehen. Zudem ist es durch die neue Technologie möglich, den Beton an mehreren Baustellen in kleinen Teil-Chargen anzuliefern, die dann vor Ort abbindefertig angemischt werden.An essential aspect of the invention is that the binder / aggregate mixture delivered by the transport vehicle is not yet ready for setting, which is why it can be transported as long as desired without the quality of processing of the mixture being adversely affected by intermediate setting during transport. In addition, the dry building material is ideally homogenized at the construction site so that a consistently high quality of the ready-to-use building material is guaranteed over the entire delivery period. Furthermore, the mixture can be better tailored to the processing needs at the construction site. Preferably, a container and a Zudosiereinrichtung for the accelerator is provided on the transport vehicle. In addition, the new technology makes it possible to deliver the concrete at several construction sites in small partial batches, which are then mixed ready-to-use on site.

Der Rohrmischer zum verarbeitungsfertigen Anmischen des Gemischs muss nicht an dem Transportfahrzeug angekoppelt sein, sondern kann auch an der Baustelle vorgesehen sein.The tube mixer for ready mixing of the mixture need not be coupled to the transport vehicle, but may also be provided at the site.

Der Rohrmischer ist in Fig. 1 in seiner Benutzungsstellung dargestellt, in welcher er parallel zur Längsachse des Fahrzeugs angeordnet werden kann. Der Rohrmischer 20 ist vorzugsweise auf einer Drehachse 24 schwenkbar auf dem Transportfahrzeug 10 gehalten, so dass das Misch- und Förderrohr 25 je nach Bedarf in eine günstige Position geschwenkt werden kann. Weiterhin ist vorzugsweise eine Höhenjustage 26 mit einer Kurbel vorgesehen, mit welcher das Auslassende 28 des Misch- und Förderrohrs 25 höher oder niedriger positioniert werden kann. In einer neutralen Stellung ist das Misch- und Förderrohr 25 im Wesentlichen horizontal ausgerichtet.The pipe mixer is in Fig. 1 shown in its position of use, in which it can be arranged parallel to the longitudinal axis of the vehicle. The tube mixer 20 is preferably held on a rotation axis 24 pivotally mounted on the transport vehicle 10, so that the mixing and conveying pipe 25 can be pivoted as needed in a favorable position. Furthermore, a height adjustment 26 is preferably provided with a crank, with which the outlet end 28 of the mixing and conveying pipe 25 can be positioned higher or lower. In a neutral position, the mixing and conveying pipe 25 is aligned substantially horizontally.

Der Rohrmischer kann jedoch auch starr, d.h. nicht drehbar, auf dem Transportfahrzeug festgelegt oder festlegbar sein.However, the tube mixer may also be rigid, i. not rotatable, be fixed or fixable on the transport vehicle.

Der Rohrmischer 20 enthält weiterhin einen Antrieb 30, der an einem Mischereinlaufrohr 32 angeflanscht ist. Das Mischereinlaufrohr 32 weist an seiner Oberseite einen Trichter 34 auf, über welchen das Trockenbetongemisch aus der Mischtrommel 14 in den Rohmischer 20 überführt werden kann. Optional lässt sich noch eine Schütte 36 mit dem Auslass 18 der Mischtrommel 14 verbinden. Der Motor kann auch durch einen Hydraulik- oder Pneumatikantrieb gebildet sein.The pipe mixer 20 further includes a drive 30 which is connected to a mixer inlet pipe 32nd is flanged. The mixer inlet pipe 32 has on its upper side a funnel 34, via which the dry concrete mixture from the mixing drum 14 can be transferred into the raw mixer 20. Optionally, a chute 36 can still be connected to the outlet 18 of the mixing drum 14. The engine may also be formed by a hydraulic or pneumatic drive.

Das Misch- und Förderrohr ist über ein Gelenk 38 mit dem Mischereinlaufrohr 32 verbunden (Fig. 3) , so dass das längliche Misch- und Förderrohr 25 aus einer Betriebsposition A parallel zur Längsachse des Fahrzeugs (Fig. 1 und 2) in eine Transportstellung B schwenkbar ist, in welcher das Misch- und Förderrohr derart relativ zur Längsachse des Fahrzeugs 10 geneigt ist, dass der Rohrmischer 20 nicht hinten über das Fahrzeugende hinaus steht.The mixing and conveying pipe is connected via a joint 38 with the mixer inlet pipe 32 ( Fig. 3 ), so that the elongated mixing and conveying pipe 25 from an operating position A parallel to the longitudinal axis of the vehicle ( Fig. 1 and 2 ) is pivotable in a transport position B, in which the mixing and conveying pipe is inclined relative to the longitudinal axis of the vehicle 10 so that the pipe mixer 20 does not stand behind the vehicle end out.

Die Verschwenkung erfolgt vorzugsweise über eine vertikale Achse, kann jedoch auch über eine horizontale oder geneigte Achse erfolgen.The pivoting is preferably via a vertical axis, but can also take place via a horizontal or inclined axis.

Hierfür ist in dem Rohrmischer vorzugsweise eine lösbare Kupplung für die in der länglichen Misch- und Förderrohr 25 angeordnete Misch- und Förderschnecke vorgesehen, über welche sich diese an die Antriebswelle am Auslassende des Mischereinlaufrohrs 32 anflanschen lässt.For this purpose, a releasable coupling is preferably provided in the pipe mixer for the mixing and conveying screw arranged in the elongate mixing and conveying pipe 25, via which it can be flanged to the drive shaft at the outlet end of the mixer inlet pipe 32.

Der Rohrmischer 20 ist vorzugsweise, aber nicht unbedingt lösbar an dem Fahrzeug 10 gehalten.The tube mixer 20 is preferably but not necessarily releasably held to the vehicle 10.

Statt oder zusätzlich zu einer Verschwenkbarkeit zwischen Mischereinlaufrohr 32 und Misch-und Förderrohr 25 kann es auch vorgesehen sein, dass nicht nur das Förder- und Mischrohr 25 sondern zusammen damit der gesamte Rohrmischer 20 derart schwenkbar 24 auf dem Transportfahrzeug 10 gehalten ist, dass er nicht hinten über das Fahrzeugende hinaus steht.Instead of or in addition to a pivotability between mixer inlet pipe 32 and mixing and conveying pipe 25, it may also be provided that not only the conveying and mixing pipe 25 but together with the entire pipe mixer 20 is pivotally mounted on the transport vehicle 10 that he is not at the rear beyond the end of the vehicle.

Das Mischereinlaufrohr dient dazu, das Gemisch aus dem Mischbehälter 14 mit Wasser und gegebenenfalls Zuschlagsstoffen in Verbindung zu bringen, wobei die intensiver Durchmischung dann in dem Misch- und Förderrohr 25 erfolgt.The mixer inlet pipe serves to bring the mixture from the mixing tank 14 into contact with water and optionally additives, the intensive mixing then taking place in the mixing and conveying pipe 25.
