Abstract

The object is an as far as possible shockless conveyance of the concrete and a high mobility of the combination device. The shockless conveyance is achieved by using a hose pump (3) of slowly opening and closing cross-section for the pressure-side delivery and the suction-side admission of the material. The mobility is achieved by the coaxial or axially parallel arrangement of transporting mixer (2) and hose pump (3), permitting a short design, and by reducing the dynamic shock loads acting on the combination device. <IMAGE>

Description

Die Erfindung betrifft eine Transport-, Misch- und Förderkombination zur Herstellung und Auf­rechterhaltung der Mischqualität breiiger Massen, insbesondere von Zementbeton, ausgebildet für die Übergabe des Gutes in eine für die Förderung die­ser Masse geeigneten Pumpe über einen Aufgabebe­hälter, wobei mit dem Transportmischer die Pumpe, sowie in aller Regel auch ein Verteilermast ge­meinsam auf einem Fahrzeug angeordnet sind.The invention relates to a transport, mixing and conveying combination for the production and maintenance of the mixing quality of pulpy masses, in particular of cement concrete, designed for the transfer of the material into a pump suitable for conveying this mass via a feed container, the pump, and, as a rule, a distribution boom are arranged together on one vehicle.

Kombinationen von Transportmischern und normalen Kolbenpumpen sind anundfürsich bekannt.
Hierbei wird insbesondere auf Ausführungen deut­scher Wettbewerbsfirmen hingewiesen.
Combinations of transport mixers and normal piston pumps are known per se.
Attention is drawn in particular to statements by German competition companies.

Diese Kombinationen beruhen ausschließlich auf der Verbindung von Kolbenpumpen mit Fahrmischern. Sie sind in der Regel für den Einsatz auf kleineren bis mittleren Baustellen vorgesehen.
Da sich ihre Förderleistung praktisch nicht regeln läßt, ist ihr Einsatz auf Kleinbaustellen, z.B. für das Vergießen von Fundamenten oder Decken, wenig geeignet, da die Möglichkeit der exakten Volumen­dosierung für die Verfüllung von durch Ver­schalungen vorbestimmten kleineren Hohlräumen, wie sie beispielsweise auch durch Pfeiler, Stürze usw. gegeben sind, fehlt.
These combinations are based exclusively on the connection of piston pumps with truck mixers. They are generally intended for use on small to medium-sized construction sites.
Since their conveying capacity cannot be regulated practically, their use on small construction sites, e.g. for pouring foundations or ceilings, is not very suitable, since the possibility of exact volume metering for the filling of smaller cavities predetermined by formwork, such as those also used for pillars, Falls, etc. are missing.

Ein weiteres Handicap dieser Ausführungen ist durch die Tatsache bestimmt,
daß die beim üblichen Zweizylinder-Betrieb ent­stehenden Umschaltstöße, bedingt durch die Steue­rung, erheblich sind, da die dabei gegebene Unter­brechung des Gutstromes nahezu schlagartig erfolgt.
Another handicap of these statements is determined by the fact
that the switching surges that occur during normal two-cylinder operation are considerable, due to the control, since the interruption of the flow of material that is given takes place almost suddenly.

Diese Schaltstöße verhindern eine exakte zwiel­genaue Einbringung des Betons in die zu verfül­lenden Bereiche und stellen eine erhebliche Bean­spruchung für die den Abgabeschlauch führende Per­son dar.
Darüberhinaus ist die Eignung dieser Mischer ins­besondere für den Einsatz in Wohngebieten als einge­schränkt zu bezeichnen, da der Betrieb mit einer er­heblichen Geräuschbildung, hervorgerufen durch die Schaltstöße, verbunden ist.
These switching impacts prevent the concrete from being precisely inserted into the areas to be filled and represent a considerable strain on the person guiding the discharge hose.
In addition, the suitability of these mixers, particularly for use in residential areas, can be described as limited, since the operation is associated with considerable noise, caused by the switching surges.

Auch läßt die Mobilität einer solchen Kombination zu wünschen übrig, da die Kolbenpumpen in den Be­reichen gleicher Leistung schwerer bauen und durch ihre dynamische Beanspruchung besonders schwer kon­zipierte Abstützmittel erfordern, die entsprechende Aufstützflächen auf jeder Baustelle, bei oft sehr eingeengten Aufstellmöglichkeiten, notwendig machen.The mobility of such a combination also leaves something to be desired, since the piston pumps are more difficult to build in the areas of the same output and, due to their dynamic load, require support means that are particularly heavy in design, which make the corresponding support surfaces necessary on every construction site, often with very limited installation options.

Dies berücksichtigend ist es Aufgabe dieser Er­findung, eine Transport-, Misch- und Förderkombi­nation nach der eingangs beschriebenen Art zu nennen, deren Leistung über einen breiten Bereich, bei praktisch stoßfreiem Betrieb, hochvariabel ist, die eine exakte manuelle Führung des Gutes über den Abgabeschlauch in das zu verfüllende Objekt ermöglicht, deren abstützung durch ge­ringe dynamische Stoßbelastung wenig Vor­bereitung des Abstützgrundes und in Verbindung mit dem Ziel, mehrere kleinere Baustellen hinter­einander versorgen zu können, hochmobil ist.Taking this into account, it is the object of this invention to name a transport, mixing and conveying combination according to the type described in the introduction, the performance of which is highly variable over a wide range, with practically bumpless operation, which enables exact manual guiding of the goods via the discharge hose into the object to be filled, the support of which is highly mobile due to the low dynamic impact load, little preparation of the support base and in connection with the goal of being able to supply several smaller construction sites in succession.

Die erfindungsgemäße Lösung dieser Aufgabe sieht vor,
daß die Pumpe eine im einem geschlossenen, par­tiell evakuierten zylindrischen Gehäuse ausge­bildete, mit einem stufenlosen, leistungssteuern­den Antriebsaggregat ausgerüstete Schlauchpumpe ist, wobei die Ausrichtung des Antriebes der Schlauchpumpe koaxial oder achsparallel zur hori­zontal projizierten Achse der Transportmischers angeordnet ist.
The solution to this problem according to the invention provides
that the pump is in a closed, partially evacuated cylindrical housing, equipped with a stepless, power-controlling drive unit hose pump, the orientation of the drive of the hose pump being arranged coaxially or axially parallel to the horizontally projected axis of the transport mixer.

Der stufenlose, leistungssteuernde Antrieb der Schlauchpumpe ermöglicht die exakte führbare, praktisch stoßfreie Abgabe des Gutes, da sich der Ab­schluß des Schlauches durch die saugseitige Quetsch­rolle bei relativ sich langsam schließendem und die Abgabe in den in die Förderleitung überführenden Druckanschluß bei langsam sich öffnendem Schlauch­querschnitt vollzieht.The infinitely variable, power-controlling drive of the peristaltic pump enables the exact, practically bumpless delivery of the material, since the hose is closed by the suction-side squeeze roller with a relatively slow closing and the delivery into the pressure connection into the delivery line with a slowly opening hose cross-section.

Die Reduzierung der dynamischen Belastung der Kombination in Verbindung mit dem einstellbaren großen Leistungsbereich, der letztlich Einstel­lungen von einer quasi gegen Null gehenden Mini­malleistung bis zu der dimensionsbedingten Maxi­malleistung zuläßt, ist bereits ein bestimmender Beitrag zur Lösung der durch die Aufgabenstellung angesprochenen Probleme.The reduction in the dynamic load of the combination in connection with the adjustable large power range, which ultimately allows settings from a quasi-zero minimum power to the dimension-related maximum power, is already a decisive contribution to solving the problems addressed by the task.

Die erfindungsgemäße Kombination ist als ein nahezu ideales Instrumentarium für eine schnell hintereinander zu erfolgende Versorgung mehrerer Baustellen zu betrachten.
Die koaxiale oder achsparallele Anordnung der Schlauchpumpe zur projizierten Achse des Trans­portmischers erlaubt eine kurze Bauweise, die auch in Verbindung mit der durch die Wahl der Pumpe be­dingten Gewichtsreduzierung - auch der Stützelemente - und der Vorbereitungen für die Aufstellung, insge­samt betrachtet, eine wesentliche Steigerung der Mobilität der Kombination beeinhaltet.
Selbstverständlich kann die Transport-, Misch- und Förderkombination nicht nur für die Abwicklung von Kurzeinsätzen herangezogen werden, sondern auch für einen praktischen Dauerbetrieb.
The combination according to the invention is to be regarded as an almost ideal instrument for supplying several construction sites in quick succession.
The coaxial or axially parallel arrangement of the peristaltic pump to the projected axis of the transport mixer allows a short construction, which, in combination with the weight reduction due to the choice of the pump - including the support elements - and the preparations for the installation, taken as a whole, a substantial increase in mobility the combination.
Of course, the transport, mixing and conveying combination can not only be used for handling short assignments, but also for practical continuous operation.

So ist auch vorgesehen, daß der der Schlauchpumpe verbundene Aufgabebehälter so dimensioniert ist, daß bei Vollzug der Restentleerung des in der Kombination gebundenen Transportmischers jeweils über die Schurre weitere Transportmischer eben­falls über den Aufgabebehälter zur Anschlußent­leerung verbracht werden können.It is also provided that the feed container connected to the peristaltic pump is dimensioned in such a way that that when the residual emptying of the transport mixer bound in the combination has been carried out, further transport mixers can also be moved via the chute to the connection container for emptying the connection.

Zur Ausbildung und Anordnung des Verteilermastes ist festzuhalten, daß dieser durch einen mit einem Tragkörper verbundenen Mastbock, der mit einem oder mehreren angelenkten Mastarmen ausgerüstet ist, ausgebildet ist, und daß der Druckanschluß der Schlauchpumpe über eine Förderleitung dem Verteiler­mast angeschlossen ist.For the formation and arrangement of the distribution boom it should be noted that this is formed by a mast bracket connected to a supporting body, which is equipped with one or more articulated boom arms, and that the pressure connection of the hose pump is connected to the distribution boom via a delivery line.

Bei der notwendigen Verwendung von mehr als zwei Mastarmen können diese in Z- oder Rollfaltung mit­einander verbunden sein.
Die Wahl der Faltung richtet sich nach den Erforder­nissen der Baustelle.
If more than two mast arms are required, they can be connected to each other in a Z or roll fold.
The choice of folding depends on the requirements of the construction site.

Die in der Regel zum Verteilermast führende, vom Druckanschluß der Schlauchpumpe abgehende Förder­leitung kann auch direkt mit weiteren zur Einbau­stelle führenden Förderleitungen verbunden sein.The delivery line, which generally leads to the distribution boom and goes out from the pressure connection of the peristaltic pump, can also be connected directly to other delivery lines leading to the installation site.

Abschließend ist darauf hinzuweisen, daß der An­trieb für die Schlauchpumpe, die Steuerung des Mastes und für den Transportmischer einzelne Hy­draulikmotore vorsieht, die durch eine oder ge­trennt durch mehrere Hydraulikpumpe (n) antreibbar ist bzw. sind, und
daß die Hydraulikpumpen durch den Fahrzeug­motor oder einen oder mehrere separaten Ver­brennungsmotor(e) antreibbar sind.
In conclusion, it should be pointed out that the drive for the hose pump, the control of the mast and for the transport mixer provides individual hydraulic motors which can be driven by one or separately by a plurality of hydraulic pumps, and
that the hydraulic pumps can be driven by the vehicle engine or one or more separate internal combustion engines.

The subject matter of the invention is explained in more detail with reference to the drawings, some of which are schematic representations of an exemplary embodiment.
  • Figure 1 shows the carrier vehicle with its superstructures, ie the truck mixer, the peristaltic pump and the placing boom.
  • FIG. 2 shows the rear view from FIG. 1.
  • Figure 3 shows a schematic representation of the hose pump connected to a feed container in combination with the truck mixer and the boom, as well as the possibility of good feed by further truck mixers (one after the other).

Das Trägerfahrzeug 1 für die Aufnahme der Kombi­nation aus Transportmischer 2, Schlauchpumpe 3, Verteilermast 4,
einschließlich den ergänzenden Antriebs- und Baugruppen, die im einzelnen noch gesondert erwähnt werden, ist in diesem Fall ein normaler LKW.
Der Fahrzeugrahmen 1.1 ist zusätzlich mit Hilfs­rahmen bzw. ergänzenden Traversen versehen, wobei der Transportmischer 2 und die Antriebseinheit 2.1 durch Quertraversen 2.3 getragen werden, während die Lasten der Schlauchpumpe 3 durch mit dem Fahr­zeugrahmen 1.1 verbundene Stützteile 3.7 und der Verteilermast 4 durch einen Tragkörper aufge­nommen werden.
Die einzelnen Tragteile können fallweise, d.h. fahr­zeugabhängig, miteinander verbunden sein.
The carrier vehicle 1 for receiving the combination of transport mixer 2, hose pump 3, placing boom 4,
in this case, including the additional drive and assemblies, which are mentioned separately in detail, is a normal truck.
The vehicle frame 1.1 is additionally provided with subframes or additional traverses, the transport mixer 2 and the drive unit 2.1 being carried by cross members 2.3, while the loads of the peristaltic pump 3 are borne by support parts 3.7 connected to the vehicle frame 1.1 and the placing boom 4 by a supporting body .
The individual supporting parts can be connected to one another on a case-by-case basis, ie depending on the vehicle.

Der Transportmischer 2 wird durch die Antriebsein­heit 2.1 angetrieben und besitzt eine in der Regel zum Aufgabebehälter 3.1 der Schlauchpumpe 3 ge­richtete schwenkbare Austragsschurre 2.2, die auch so geschwenkt werden kann, daß das Mischgut direkt, ohne über die Pumpe gefördert zu werden, in eine bauseitige Aufgabestelle abgegeben bzw. Restmisch­gut auf einen auf der Baustelle vorgesehenen Platz entleert werden kann.The transport mixer 2 is driven by the drive unit 2.1 and has a pivotable discharge chute 2.2 which is generally directed towards the feed container 3.1 of the peristaltic pump 3 and which can also be pivoted in such a way that the mix is conveyed directly to an on-site feed point without being conveyed by the pump dispensed or residual mix can be emptied into a space provided on the construction site.

Das in den Aufgabebehälter 3.1 aufgegebene Gut wird über den Sauganschluß 3.2 unmittelbar dem Pumpschlauch 3.0 der Schlauchpumpe 3 zugeführt.The material fed into the feed container 3.1 is fed directly to the pump hose 3.0 of the hose pump 3 via the suction connection 3.2.

Der Pumpschlauch 3.0 ist über∼170° entlang der zylindrischen Wandung des Pumpgehäuses 3.5 ge­lenkt, wobei der durch die beiden Quetschrollen 3.4 gefüllte Abschnitt bei Weiterdrehung des Quetsch­rollenrotors über den Druckanschluß 3.3 in die zum Verteilermast 4 führende Förderleitung 3.8 entleert; hierbei wird die in Erscheinung tretende Schlauch­längung durch eine stützende Gleitlafette 3.6 kom­pensiert.
Die partielle Evakuierung des Gehäuses 3.5 be­schleunigt die Rückbildung des Pumpschlauches 3.0 in seinen zylindrischen Querschnitt, so daß praktisch immer der volle Ansaug- und Förderquerschnitt ge­geben ist.
The pump hose 3.0 is steered over ∼170 ° along the cylindrical wall of the pump housing 3.5, the section filled by the two pinch rollers 3.4 being emptied as the pinch roller rotor continues to rotate via the pressure connection 3.3 into the delivery line 3.8 leading to the placing mast 4; Here the emerging tube elongation is compensated for by a supporting slide mount 3.6.
The partial evacuation of the housing 3.5 accelerates the regression of the pump tubing 3.0 into its cylindrical cross section, so that practically the full suction and delivery cross section is always given.

Die Quetschrollen 3.4 sind dabei in ihrer Größe so gehalten, daß eine sehr weiche druckseitige Ab­gabe bzw. ein ebenso weicher saugseitiger Eingriff stattfindet.
Mit anderen Worten: der Abschluß des Schlauches 3.0 durch die saugseitige Quetschrolle 3.4 erfolgt bei relativ sich langsam schließendem und die Abgabe in den Druckanschluß bei langsam sich öffnendem Schlauch­querschnitt.
Dies ist, wie bereits erwähnt, eine der wesentlichsten Vorteile dieses Pumptypes, da die zielgenaue Aufgabe des Gutes, z.B. in ein Fundament, durch die das Schlauchende führende Person nicht unbillig durch starke Schalt- bzw. Rückstöße gestört wird.
The squeeze rollers 3.4 are kept in size so that a very soft pressure-side delivery or an equally soft suction-side intervention takes place.
In other words: the hose 3.0 is closed by the suction-side pinch roller 3.4 with a relatively slowly closing hose cross-section and the delivery into the pressure connection with a slowly opening hose cross-section.
As already mentioned, this is one of the most important advantages of this type of pump, since the precise feeding of the goods, eg into a foundation, by which the person guiding the hose end is not unduly disturbed by strong switching or recoil.

Der Antrieb der Schlauchpumpe 3 erfolgt stufen­los, so daß eine Einstellung der Leistung von "O" bis "max" möglich ist.The drive of the peristaltic pump 3 is infinitely variable, so that the output can be adjusted from "O" to "max".

Der Verteilermast 4 erlaubt die hochmobile exakte Einlenkung in die gewünschte Abgabestellung, wo­bei dieser im wesentlichen aus einem pyramiden­stumpfförmigen Tragkörper 4.1, einem Mastbock 4.2 und den hier angelenkten Mastarmen 4.3 besteht. Die Anzahl der Mastarme 4.3 bzw. deren Verbindung in Z- oder Rollanordnung wird durch die Forderung der Baustelle bestimmt. Im Bereich des Mastbockes sind verstellbare Abstützungen vorgesehen.
Unabhängig von der Abgabe des Gutes aus dem Trans­portmischer 2 ist es jederzeit möglich, bei Ver­brauch des Inhaltes, einen Transportmischer 2ʹ zu dem Aufgabebehälter 3.1 in eine solche Position zu verbringen, daß dieser über dessen Schwenkschurre 2.2ʹ in den Aufgabebehälter 3.1 entleert.
The placing boom 4 allows highly mobile, precise steering into the desired delivery position, which essentially consists of a truncated pyramid-shaped support body 4.1, a mast bracket 4.2 and the mast arms 4.3 articulated here. The number of mast arms 4.3 or their connection in a Z or roll arrangement is determined by the requirements of the construction site. Adjustable supports are provided in the area of the mast bracket.
Regardless of the delivery of the goods from the transport mixer 2, it is possible at any time, when the contents are consumed, to bring a transport mixer 2 'to the feed container 3.1 into such a position that it empties into the feed container 3.1 via its pivoting chute 2.2'.

Es kann also, bei entsprechender Disposition, prak­tisch pausenlos gefördert werden.With appropriate planning, it can therefore be funded practically non-stop.
