Description

Die Erfindung betrifft einen Kransilo für den Transport schüttfähiger Baustoffe wie Beton, Kies, Sand oder dgl., mit einem zur Aufnahme der Baustoffe ausgebildeten Behälter, der an einem oberen Ende eine Einfüllöffnung zur Beschickung und an einem unteren Ende eine Entleerungsöffnung zur Entnahme der Baustoffe über einen hängend befestigten Förderschlauch aufweist, und mit einem auf den Boden abstellbaren Traggestell verbunden ist.
Solche Kransilos sind u.a. durch die EP 1'830'017 A1 bekannt und werden insbesondere bei der Verarbeitung von Beton, vornehmlich Selbstverdichtendem Beton SCC (Self Compacting Concrete) oder neuerdings auch bei zähfliessendem Beton eingesetzt. Der selbstverdichtende Beton weist einen hohen Flüssigkeitsanteil resp. eine günstige Fliessfähigkeit auf. Die sich durch das hohe Eigengewicht und das flüssige Vorkommen selbst verdichtende Masse wird aus dem Kransilo über einen Förderschlauch einem eingeschalten Hohlraum zugeführt. Durch die durch den Förderschlauch entstehende zusätzliche Fallhöhe wird die Verdichtung der Betonmasse in der Schalung intensiviert, sodass auf den Einsatz von Verdichtungsgeräten weitgehend verzichtet werden kann.
Vermehrt werden diese Kransilos, ob mit mehreckigem, kreisrundem und/oder ovalem lem Behälterquerschnitt, mit Schlauchauslauf auch für die Verarbeitung von zähflüssigem Beton verwendet, da der Querschnitt des Förderschlauches und der leichtere Umgang mit dem Schlauch für eine bessere Zugänglichkeit zu den Schalungshohlräumen genutzt werden kann.
The invention relates to a crane silo for the transport of pourable building materials such as concrete, gravel, sand or the like., Formed with a receptacle for building materials container at an upper end of a filling opening for charging and at a lower end a discharge opening for removal of the building materials has a hanging attached conveyor hose, and is connected to a storeable on the floor support frame.
Such Kransilos are among others by the EP 1'830'017 A1 are known and used in particular in the processing of concrete, mainly self-compacting concrete SCC (Self Compacting Concrete) or recently also in slow-flowing concrete. The self-compacting concrete has a high liquid content resp. a favorable flowability. The self-compacting mass, which is self-compacting due to its high weight and liquid deposits, is fed from the crane silo via a delivery hose to a cavity that is turned on. Due to the additional drop height created by the delivery hose, the compression of the concrete mass in the formwork is intensified so that the use of compacting equipment can be largely dispensed with.
These kransilos, whether polygonal, circular and / or oval, are becoming more common The cross-section of the delivery hose and the easier handling of the hose can be used for better accessibility to the formwork cavities.

Dennoch tritt bei einer Schlauchentleerung des Behälters u.a. der Umstand ein, dass vor der Entnahme der flüssigen Masse aus dem Behälter und zum Unterbruch der Zuführung der Betonmasse über den Förderschlauch, letzterer um 180° umgeknickt wird, wobei bei unvollständiger Behälterentleerung ein Rest der Betonmasse im umgeknickten oberen Abschnitt des Förderschlauches verbleibt. Der unbequemere Umgang mit dem Förderschlauch wirkt sich nachteilig auf die Arbeitssicherheit des Bedienungspersonals aus und beeinträchtigt die ArbeitsleistungNevertheless occurs in a hose emptying of the container u.a. the fact that prior to the removal of the liquid mass from the container and the interruption of the supply of concrete mass on the delivery hose, the latter is bent over by 180 °, with incomplete container emptying a remainder of the concrete mass remains in the folded upper portion of the delivery hose. The more uncomfortable handling of the delivery hose has a detrimental effect on the occupational safety of the operating personnel and impairs the work performance

Die vorveröffentlichte DE 102 60 661 A1 vermittelt eine Transportvorrichtung zum Transportieren eines Schüttguts, auch Betonsilo genannt, das aus einem trichterförmigen, auf dem Boden abstellbaren Behälter zur Aufnahme von Schüttgut besteht, der im unteren Behälterbereich eine mit einer Verschlusseinheit in Verbindung stehende Auslassöffnung aufweist.The pre-published DE 102 60 661 A1 provides a transport device for transporting a bulk material, also called concrete silo, which consists of a funnel-shaped, settable on the ground container for receiving bulk material, which has in the lower container area an outlet opening in communication with a closure unit.

Die bekannte CH 494695 A beschreibt einen Beton-Transportkübel, der einen etwa kegelförmigen Behälter aus Kunststoff aufweist, dessen Unterteil durch ein aus Kunststoff bestehendes, durch einen Klemmverschluss zusammendrückbares Rohr verlängert ist.The well-known CH 494695 A describes a concrete transport bucket having an approximately conical plastic container, the lower part is extended by a plastic existing, squeezable by a clamp closure tube.

Deshalb stellt sich an die Erfindung die Aufgabe, einen Kransilo der eingangs beschriebenen Art zu schaffen, mit dem die genannten Mängel behoben und die Effizienz der Verarbeitung der zugeführten, wenigstens teilweise flüssigen Masse gesteigert werden kann.Therefore, the object of the invention to provide a crane silo of the type described above, with which the aforementioned deficiencies resolved and increased the efficiency of processing the supplied, at least partially liquid mass can be.

Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass an dem unteren Ende des Behälters, in Entleerungsrichtung an die Entleerungsöffnung anschliessend, eine auf den Förderschlauch zur Aenderung des Förderquerschnitts einwirkende, verstellbare Dosiervorrichtung angeordnet ist, die an einem Gestell befestigte, von wenigs-tens einer Seite auf den nach unten gerichteten Förderschlauch zustell- und zurückversetzbare Dosierbalken aufweist, die zur Einstellung und Verstellung mit einer Betätigungsvorrichtung verbunden sind und bei zusammengepresstem Förderschlauch in dessen Längsrichtung versetzt angeordnet sind, sodass eine genaue Dosierung der zu verarbeitenden Menge erreicht werden kann.According to the invention, the object is achieved in that at the lower end of the container, in the emptying direction to the discharge opening, an acting on the delivery hose for changing the delivery cross-section, adjustable metering device is arranged, attached to a frame, from at least one side has the downwardly directed delivery hose and zurückversetzbare Dosierbalken, which are connected for adjustment and adjustment with an actuator and are arranged offset in the longitudinal direction of compressed conveyor hose, so that a precise dosage of the amount to be processed can be achieved.

Die Erfindung schafft die Möglichkeit, bestehende Kransilos, wie beispielsweise in der CH 685 831 A beschrieben, für die Beschickung von Hohlräumen mit flüssigen Baustoffen mit einer Vorrichtung nach der vorgeschlagenen Lösung auszustatten oder einen Kransilo mit der vorgeschlagenen Lösung herzustellen.The invention provides the possibility of existing crane silos, such as in the CH 685 831 A described to equip for the loading of cavities with liquid building materials with a device according to the proposed solution or to produce a kransilo with the proposed solution.

Für bestehende Kransilos ist es vorteilhaft, wenn die Dosiervorrichtung an dem Behälter oder an Teilen des Kransilos lösbar resp. abnehmbar befestigt ist. Damit lässt sich ein mit einer betätigbaren Verschlussvorrichtung ausgebildeten Entleerungsöffnung versehenes Kransilo auf einfache Art zur Schlauchentleerung umbauen resp. umrüsten.For existing crane silos, it is advantageous if the metering device on the container or on parts of the crane silo releasably resp. is detachably attached. In this way, a crane silo provided with an emptying opening provided with an operable closure device can be converted in a simple manner for evacuating the tube, resp. convert.

Als zweckdienlich erweist es sich dann, wenn die Dosiervorrichtung an einer Verschlussvorrichtung des Behälters oder an Teilen davon lösbar resp. abnehmbar befestigt ist.
In diesem Fall kann die Dosiervorrichtung an der Entleerungsöffnung zwischen zwei zum Oeffnen und Schliessen des Behälters betätigbaren Verschlussklappen einer Verschlussvorrichtung des Kransilos, beispielsweise an Schieberelementen (siehe EP 1 830 017 A1 oder CH 685 831 A5 ) bei geöffneter Verschlussvorrichtung eingehängt resp. eingespannt werden. Der Förderschlauch wäre sodann oberhalb der Dosierbalken, an einer mit dem Gestell der Dosiervorrichtung verbundenen Halterung befestigt. Diese Halterung, an der der Förderschlauch mit einer Bride oder dgl. befestigt sein kann, ist vorteilhaft angepasst an die Verschlussöffnung resp. als Uebergang zum Förderschlauch rechteckig resp. oval ausgebildet, sodass ein störungsfreier Fluss der Betonmasse aus der Verschlussvorrichtung entstehen kann.
It proves to be expedient if the metering device on a closure device of the container or on parts thereof releasably resp. is detachably attached.
In this case, the metering device at the discharge opening between two operable to open and close the container closure flaps of a closure device of the crane silo, for example on slide elements (see EP 1 830 017 A1 or CH 685 831 A5 ) hung with open closure device resp. be clamped. The delivery hose would then be fastened above the metering bars to a holder connected to the frame of the metering device. This holder to which the delivery hose with a Bride or the like. May be attached, is advantageously adapted to the closure opening, respectively. as a transition to the delivery hose rectangular resp. formed oval, so that a trouble-free flow of the concrete mass can arise from the closure device.

Alternativ kann die Dosiervorrichtung mit dem Kransilo oder Teilen davon fest verbunden sein.Alternatively, the metering device may be firmly connected to the crane silo or parts thereof.

Gemäß der Erfindung weist die Dosiervorrichtung an einem Gestell befestigte, von wenigstens einer Seite auf den nach unten gerichteten Förderschlauch zustell- und zurückversetzbare Dosierbalken auf, die mit einer Betätigungsvorrichtung verbunden ist und gegen den anderen zustell- und zurückversetzbar ist.According to the invention, the metering device attached to a frame, from at least one side of the downwardly directed delivery hose deliverable and rücksetzsetzbaren Dosierbalken, which is connected to an actuator and is against the other zuell- and zurückversetzbar.

Gemäss einer weiteren Möglichkeit sind beide Dosierbalken mit einer Betätigungsvorrichtung verbunden, sodass sie von beiden Seiten auf den Förderschlauch zustell- und zurückversetzbar sind.According to another possibility, both metering bars are connected to an actuating device, so that they can be brought back and forth on both sides of the delivery hose.

Zweckmässig sind die Dosierbalken in einer Ausserbetriebsstellung etwa annähernd gleichmässsig verteilt zum Durchlass- oder Förderquerschnitt des Förderschlauches angeordnet, wobei bei einer Dosiervorrichtung mit einem betätigbaren Dosierbalken dieser wenigstens den Weg des Durchmessers des Förderschlauches zu dessen Verschluss zurückzulegen hat, wogegen bei zwei Dosierbalken diese zum Verschluss jeweils den Weg des halben Förderschlauchdurchmessers zurückzulegen haben.Appropriately, the Dosierbalken in an inoperative position are approximately evenly distributed to Durchlass- or conveyor cross section of the delivery hose arranged at a metering device with an actuatable Dosierbalken this at least the path of the diameter of the delivery hose has to cover to its closure, whereas in two Dosierbalken these for closure respectively have to cover the path of half the delivery hose diameter.

Gemäß der Erfindung sind die Dosierbalken zumindest in der Betriebsstellung resp. bei zusammengepresstem Förderschlauch in dessen Längserstreckungsrichtung versetzt zueinander angeordnet, sodass die in den zu verarbeitenden Baustoffen vorkommenden Steine zwischen den Dosierbalken nicht eingeklemmt werden, so dass ein absoluter Verschluss des Förderschlauches entstehen kann. Dabei wird der Förderschlauch an der Dosiervorrichtung umgelenkt und der Förderweg unterbrochen. Der Abstand der sich in der Betriebsstellung etwa übereinander befindenden Dosierbalken entspricht etwa der zweifachen Wandstärke des Förderschlauches.According to the invention, the Dosierbalken at least in the operating position, respectively. arranged in the longitudinal direction of extension of compressed conveyor hose in the longitudinal direction, so that the occurring in the building materials to be processed stones are not trapped between the Dosierbalken, so that an absolute closure of the delivery hose can arise. In this case, the delivery hose is deflected at the metering device and the delivery path is interrupted. The distance between the metering bars located approximately one above the other in the operating position corresponds approximately to twice the wall thickness of the delivery hose.

Vorzugsweise ist wenigstens einer der Dosierbalken der Dosiervorrichtung mit einem Hebelgetriebe der Betätigungsvorrichtung verbunden.Preferably, at least one of the metering bars of the metering device is connected to a lever gear of the actuating device.

Zweckmässig wird das Hebelgetriebe durch einen Handhebel bewegt.

The hand lever can be connected in a movable metering with a one-armed lever of the lever mechanism or two movable Dosierbalken with a double arm, the free ends of the levers are respectively connected by means of handlebar (s) with a Dosierbalken.

Vorteilhaft sind die Dosierbalken resp. wenigstens der bewegliche Dosierbalken an einem mit dem Lenker verbundenen Schwenkarm befestigt, um gegen den Förderschlauch und von diesem weg bewegt werden zu können.Advantageously, the Dosierbalken resp. at least the movable Dosierbalken attached to a connected to the handlebar arm to pivot against the delivery hose and can be moved away from this.

Bei zwei beweglichen Dosierbalken der Dosiervorrichtung weisen diese der einfachheithalber eine gemeinsame Schwenkachse auf.In the case of two movable metering bars of the metering device, these have, for the sake of simplicity, a common pivot axis.

Das Gestell der Dosiervorrichtung ist vorzugsweise aus beidseits des Förderschlauches angeordneten Gestellschildern gebildet, an denen Hebelgetriebe innerhalb des Gestells befestigt sind, wobei im Interesse einer hohen Stabilität und Festigkeit an jedem Gestellschild jeweils ein mit dem anderen verbundenes Hebelgetriebe spiegelbildlich gegenüberliegend angeordnet ist.The frame of the metering device is preferably formed on both sides of the delivery hose arranged frame signs, where lever gear are mounted within the frame, wherein in the interest of high stability and strength on each frame plate each one connected to the other lever mechanism is arranged mirror-inverted opposite.

Der/die Dosierbalken können mit dem Handhebel gegen eine Rückstellkraft voneinander entfernt oder arretiert werden, sodass eine Entleerung des Behälters über den Förderschlauch stattfindet und beim Zurücklegen oder Lösen des Handhebels aus der Arretierung ein Verschluss des Förderschlauches eintritt. Selbstverständlich könnte eine Arretierung des Handhebels für verschiedene Durchsatzstufen vorgesehen werden.The / the Dosierbalken can be removed or locked with the hand lever against a restoring force, so that emptying of the container takes place on the delivery hose and entering or releasing the hand lever from the lock enters a closure of the delivery hose. Of course, a locking of the hand lever could be provided for different throughput levels.

Im Sinne einer Verbesserung der Betriebssicherheit und erleichterten Bedienbarkeit durch das Personal kann der Antrieb der Dosiervorrichtung anstelle von manuell motorisch erfolgen, indem beispielsweise ein mit der Dosiervorrichtung zum Beispiel über das Hebelgetriebe oder direkt verbundener, drehwinkelgesteuerter Elektromotor resp. ein Schrittmotor über eine manuell bedienbare Fernsteuerung gesteuert wird.In terms of improving the reliability and ease of use by the staff, the drive of the metering instead of manually by motor, for example, by a with the metering device, for example, via the lever gear or directly connected, angle-controlled electric motor resp. a stepper motor is controlled by a manually operable remote control.

Zur Erleichterung der Bedienung und Manipulation des vorgeschlagenen Kransilos kann der Förderschlauch zur Ausserbetriebnahme mittels reversierbarer Hebevorrichtung von einer Betriebs- in eine Ausserbetriebsstellung versetzt werden.To facilitate the operation and manipulation of the proposed crane silo, the delivery hose for decommissioning by means of reversible lifting device can be moved from an operating to an inoperative position.

Es erweist sich als eine einfache Ausführung, wenn die Hebevorrichtung einen den Förderschlauch hinter den Dosierbalken erfassenden und um eine horizontale Achse nach oben umlenkbaren Schwenkbock aufweist, mit dem der Förderschlauch manuell in eine Ausserbetriebslage versetzbar ist, wodurch das Kransilo zwischen Bauobjekt und Beschickungsstelle manövrierfähiger wird, ohne die Gefahr, zur Beschickung auf den Förderschlauch abgestellt werden zu können.It proves to be a simple embodiment, when the lifting device has a the delivery hose behind the metering and deflecting about a horizontal axis upwardly deflectable pivot bracket with which the delivery hose is manually displaceable in a shutdown position, whereby the crane silo between the building object and charging point is maneuverable without the risk of being able to be parked for feeding on the delivery hose.

Die Fig. 1 und 4 zeigen ein Kransilo 1 für den Transport von schüttfähigen Baustoffen wie Beton, Kies, Sand oder dgl., mit einem Behälter 2, der im oberen Bereich zylindrisch ausgebildet ist, jedoch auch einen mehreckigen Querschnitt aufweisen könnte, wie beispielsweise die Ausführung in der CH 685 831 A5 , und zu einer unteren Entleerungsöffnung 3 hin sich etwa kegelig oder pyramidenförmig resp. trichterartig verengend verläuft. Das obere Ende des Behälters 2 ist als Einfüllöffnung zur Beschickung des Behälters 2 und das untere Ende mit der Entleerungsöffnung 3 zur Entnahme eines Baustoffes ausgebildet. Die Entleerungsöffnung 3 ist mit einem Stutzen 4 versehen, an dem ein Förderschlauch 5 mittels einer den Stutzen 4 umgebenden Bride 6 befestigt ist (Fig. 1). Der Förderschlauch 5 ist in einem zusammengepressten Zustand dargestellt, d.h. das Kransilo 1 ist zur Entnahme der Baustoffe über einen Förderschlauch 5 ausgebildet. Ueberdies weist das Kransilo 1 zur Beschickung ein auf den Boden abstellbares Traggestell 7 auf, an dem der Behälter 2 befestigt ist. An dem unteren Ende des Behälters 2, in Entleerungsrichtung an die Entleerungsöffnung 3 anschliessend, ist eine auf den nach unten hängenden Förderschlauch 5 zur Aenderung des Förderquerschnitts einwirkende, verstellbare Dosiervorrichtung 8 angeordnet. Gemäss Ausführungsbeispiel ist die Dosiervorrichtung 8 an der Aussenseite des unteren sich in Förderrichtung verengenden Behälterbereichs durch Verbindungselemente 9, beispielsweise lösbar befestigt, wozu eine Schraubenverbindung 10 vorgesehen ist. Es wäre auch möglich, die Dosiervorrichtung 8 an anderen Teilen des Kransilos 1, beispielsweise an dem Traggestell 7 zu befestigen.
Es ist denkbar, die vorgeschlagene Dosiervorrichtung 8 an bestehenden Kransilos nachträglich anzubauen, um eine Förderung der Baustoffe über einen Förderschlauch vornehmen zu können. Zu diesem Zweck könnte die den Förderschlauch (wenigstens teilweise) umgebende Dosiervorrichtung 8 an einer Verschlussvorrichtung des Behälters, beispielsweise einem Klappenverschluss eines Kransilos nach der CH 685 831 A5 lösbar befestigt werden, sodass ein wahlweiser Einsatz des Kransilos möglich ist.
Die Dosiervorrichtung 8 weist an einem Gestell 11 befestigte, von beiden Seiten auf den nach unten gerichteten (hängenden) Förderschlauch 5 zustell- und zurückversetzbare Dosierbalken 12, 13 auf, die mit einer Betätigungsvorrichtung 14 verbunden sind. Die Fig. 2 und 3 verdeutlichen die Dosiervorrichtung 8 in einem vergrösserten Massstab. Das Gestell 11 besteht aus zwei beabstandeten Seitenschildern 15, 16, die durch quer verlaufende Stangen 17, 18, 19, 20 verbunden sind und das Gestell 11 stabilisieren. Die auf den Förderschlauch 5 (in den Fig. 2 und 3 nicht ersichtlich) zustell- und zurückversetzbaren Dosierbalken 12, 13 befinden sich in den Fig. 2 und 3 in der Betriebsstellung gemäss Fig. 1. In der Ausserbetriebsstellung sind die Dosierbalken 12, 13 gemäss Fig. 1 etwa gleichmässig auf den Förderquerschnitt des Förderschlauches 5 verteilt, seitlich von diesem entfernt voneinander gehalten und stellen den Förderschlauch 5 zum Durchfluss frei. Wird der Förderfluss im Förderschlauch 5 unterbrochen, nehmen die Dosierbalken 12, 13 ihre dargestellte Stellung ein und drücken den dazwischen verlaufenden Förderschlauch 5 flach zusammen. Es besteht die Möglichkeit, die Dosiervorrichtung 8 so auszubilden, dass nur einer der beiden Dosierbalken 12, 13 gegen den anderen Dosierbaken 13, 12, der stationär angeordnet ist, zu pressen.
Beim vorliegenden Ausführungsbeispiel werden beide Dosierbalken 12, 13 gegeneinander bewegt und sind zu diesem Zweck an Schwenkarmen 21, 22 im Gestell 11 schwenkbar aufgehängt. Die Schwenkarme 21, 22 weisen jeweils eine gemeinsame Schwenkachse 23, 24 auf, die in Schwenklagern 25, 26 an den Gestellschildern 15, sich gegenüberliegend angeordnet sind, wobei die Aufhängung der Dosierbalken 12, 13 an einer gemeinsamen Achse nicht zwingend ist.
Vorliegend dargestellt sind die Dosierbalken 12, 13 bei zusammengepresstem Förderschlauch 5 in dessen Längserstreckung versetzt, also höhenunterschiedlich angeordnet, damit der Förderschlauch 5 schonend zusammengepresst wird und nicht einem durch ein Aufeinanderpressen der Dosierbalken 12, 13 entstehenden Druck ausgesetzt ist. Dadurch lassen sich im Wirkbereich der Dosierbalken 12, 13 vorkommende grössere Steine im Förderschlauch 5 in Förderrichtung verschieben, sodass auch Flüssigkeits- und Feinanteile des Baustoffs zurückbleiben. Die Dosierbalken 12 und/oder 13 sind mit einem Hebelgetriebe 27, 28 der Betätigungsvorrichtung 14 verbunden, wobei die Verbindungsstellen durch jeweils einen Lenkhebel 29, 30 des Hebelgetriebes 27, 28 und dem schwenkbaren Ende der Schwenkarme 21, 22 gebildet werden. Die Lenkhebel 29, 30 sind mit ihren gegenüberliegenden Enden jeweils an den freien Enden der Hebelarme 31, 32 eines Doppelarmhebels 33 gekuppelt. Letzterer ist in einem Seitenschild 15, 16 des Gestells 11 gelagert und mit dem im gegenüberliegenden Seitenschild 16, 15 gelagerten Doppelarmhebel 33 fest verbunden. Die Betätigung des Hebelgetriebes 27, 28 erfolgt mittels Handhebel 34, der mit einem Ende an der als Welle ausgebildeten Stange 19 befestigt ist.
Ist nur ein Dosierbalken 12, 13 beweglich angeordnet, kann auf einen Lenkhebel 29, 30 verzichtet werden und der Doppelarmhebel 33 kann gegen einen Einarmhebel (nicht ersichtlich) ersetzt werden.
Die sich im Abstand gegenüberliegenden gleichartigen Hebelgetriebe 27, 28 sind jeweils an den Seitenschildern 15, 16 innerhalb des Gestells 11 angeordnet, so dass sie gegen Einwirkungen von aussen und die nähere Umgebung geschützt sind. Der oder die Dosierbalken 12, 13 werden gegen eine Rückstellkraft die auf den Handhebel 34 wirkt, voneinander entfernt resp. der Förderquerschnitt des Förderschlauchs 5 frei gegeben, wozu gemäss den Fig. 2 und 5 eine Druckfeder resp. Gasdruckfeder 36 oder eine Zugfeder 37 vorgesehen sein kann, die einenends an einem Seitenschild 15, 16 befestigt und anderenends mit einem an der Welle 19 befestigten einarmigen Hebel 38 verbunden sind.
Zur Arretierung des Handhebels 34 in der Betriebsstellung der voneinander entfernten Dosierbalken 12, 13 ist eine Klinke 39 vorgesehen, die an einen an der Aussenseite eines Seitenschildes 16 befestigten Anschlag 40 schwenkbar angelegt werden kann.
Anstelle einer manuellen Betätigung könnte die Dosiervorrichtung 8 motorisch verstellt werden. Hierzu eignet sich beispielsweise ein mit der Dosiervorrichtung 8 über das Hebelgetriebe 27, 28 oder direkt verbundener, drehwinkelgesteuerter Elektromotor resp. ein Schrittmotor, der mit einer manuell bedienbaren Fernsteuerung gesteuert werden kann.
The Fig. 1 and 4 show a crane silo 1 for the transport of free-flowing building materials such as concrete, gravel, sand or the like., With a container 2, which is cylindrical in the upper region, but could also have a polygonal cross-section, such as the execution in the CH 685 831 A5 , and to a lower discharge opening 3 out approximately conical or pyramidal respectively. funnel narrowing. The upper end of the container 2 is formed as a filling opening for charging the container 2 and the lower end with the discharge opening 3 for removing a building material. The discharge opening 3 is provided with a nozzle 4, to which a delivery hose 5 is attached by means of a clip 4 surrounding the bridge 6 ( Fig. 1 ). The delivery hose 5 is shown in a compressed state, ie the crane silo 1 is designed to remove the building materials via a delivery hose 5. In addition, the crane silo 1 for loading a can be placed on the floor support frame 7, on which the container 2 is attached. At the lower end of the container 2, in the emptying direction to the discharge opening 3 subsequently, an adjustable metering device 8 acting on the downwardly hanging delivery hose 5 for changing the delivery cross section is arranged. According to the exemplary embodiment, the metering device 8 is detachably fastened on the outside of the lower container area narrowing in the conveying direction by connecting elements 9, for which purpose a screw connection 10 is provided. It would also be possible to attach the metering device 8 to other parts of the crane silo 1, for example to the support frame 7.
It is conceivable to subsequently grow the proposed metering device 8 on existing crane silos in order to be able to convey the building materials via a delivery hose. For this purpose, the dosing device 8 surrounding the delivery hose (at least partially) could be attached to a closure device of the container, for example a flap closure of a crane silo after CH 685 831 A5 be releasably attached, so that an optional use of the crane silo is possible.
The metering device 8 has attached to a frame 11, from both sides on the downwardly directed (hanging) delivery hose 5 deliverable and zurückversetzbare Dosierbalken 12, 13, which is connected to an actuating device 14 are. The Fig. 2 and 3 illustrate the metering device 8 in an enlarged scale. The frame 11 consists of two spaced side plates 15, 16, which are connected by transverse bars 17, 18, 19, 20 and stabilize the frame 11. The on the delivery hose 5 (in the Fig. 2 and 3 not apparent) deliverable and rücksetzsetzbaren Dosierbalken 12, 13 are located in the Fig. 2 and 3 in the operating position according to Fig. 1 , In the inoperative position, the metering bars 12, 13 are according to Fig. 1 approximately evenly distributed on the conveyor cross section of the delivery hose 5, laterally held away from each other and this release the delivery hose 5 to the flow. If the delivery flow in the delivery hose 5 is interrupted, the metering bars 12, 13 assume their position shown and press the delivery hose 5 extending therebetween flat. It is possible to form the metering device 8 in such a way that only one of the two metering bars 12, 13 is pressed against the other metering bar 13, 12, which is arranged stationary.
In the present embodiment, both Dosierbalken 12, 13 are moved against each other and are pivotally suspended for this purpose on pivot arms 21, 22 in the frame 11. The pivot arms 21, 22 each have a common pivot axis 23, 24, which are arranged in pivot bearings 25, 26 on the frame plates 15, opposite one another, wherein the suspension of the metering bars 12, 13 on a common axis is not mandatory.
In the present case, the metering bars 12, 13 are offset in the longitudinal direction when the delivery hose 5 is pressed together, ie arranged at different heights, so that the delivery hose 5 is gently pressed together and is not exposed to pressure resulting from pressing the metering bars 12, 13 together. As a result, in the effective range of the metering bars 12, 13 occurring larger stones in the conveying tube 5 can be displaced in the conveying direction, so that also liquid and fines of the building material remain. The dosing bars 12 and / or 13 are connected to a lever mechanism 27, 28 of the actuator 14, wherein the connection points are each formed by a steering lever 29, 30 of the lever mechanism 27, 28 and the pivotable end of the pivot arms 21, 22. The steering levers 29, 30 are coupled with their opposite ends respectively at the free ends of the lever arms 31, 32 of a Doppelarmhebels 33. The latter is mounted in a side plate 15, 16 of the frame 11 and fixedly connected to the mounted in the opposite side plate 16, 15 Doppelarmhebel 33. The actuation of the lever mechanism 27, 28 by means of lever 34 which is fixed at one end to the shaft 19 designed as a shaft.
If only one metering bar 12, 13 arranged movably, can be dispensed with a steering lever 29, 30 and the double arm 33 can be replaced with a Einarmhebel (not shown).
The opposite at a distance similar lever mechanism 27, 28 are respectively disposed on the side plates 15, 16 within the frame 11, so that they are protected against external influences and the surrounding area. The one or more Dosierbalken 12, 13 are against a restoring force acting on the lever 34, away from each other, respectively. the conveyor cross-section of the delivery hose 5 is given freely, for which according to the Fig. 2 and 5 a compression spring resp. Gas spring 36 or a tension spring 37 may be provided, which are fixed at one end to a side plate 15, 16 and the other end connected to a shaft 19 attached to the one-armed lever 38.
To lock the hand lever 34 in the operating position of the metering bars 12, 13 remote from each other, a pawl 39 is provided which can be pivotally attached to a stop 40 mounted on the outside of a side plate 16.
Instead of a manual operation, the metering device 8 could be adjusted by motor. For example, one with the metering device 8 is suitable for this purpose the lever mechanism 27, 28 or directly connected, angle-controlled electric motor resp. a stepper motor that can be controlled with a manually operated remote control.

Der Kransilo besteht weiterhin aus einer reversierbaren Hebevorrichtung 35 für den Förderschlauch 5, mit der letzterer im hängenden Zustand aus der Betriebslage in eine Ausserbetriebslage angehoben wird, um beim Abstellen des Kransilos auf den Boden nicht eingeklemmt werden zu können.
Die Hebevorrichtung 35 besteht aus einem um eine horizontale Achse schwenkbaren Schwenkbock 41, der an dem von der Welle 19 der Betätigungsvorrichtung 14 gegenüberliegenden Ende des Gestells 11 an der als drehbare Welle ausgebildeten Stange 17 befestigt ist. Der Schwenkbock 41 ist durch jeweils zwei sich gegenüberliegende abgewinkelte Schenkel 42, 43 ausgebildet, wobei an den freien Enden der Schenkel 43 eine diese verbindende frei drehbare Walze 44 gelagert ist, die den hängenden Förderschlauch 5 beim Anheben des Schwenkbocks 41 aus der Betriebslage aushebt, so dass er auf der Walze 44 aufliegt. Die Fig. 1, 2 und 3 zeigen die Position der Hebevorrichtung 35 in der der Förderschlauch 5 nach oben ausgehoben ist. Die Betätigung der Hebevorrichtung 35 erfolgt durch eine mit der Welle 17 des Schwenkbocks 41 verbundene Kurbel 45. Hierbei wird der sich zwischen den Dosierbalken 12, 13 befindende Förderschlauch 5 durch die Walze 44 erfasst und um den in Fig. 1 gezeigten unteren Dosierbalken 13 an resp. auf der Walze 44 aufliegend nach oben in eine Ausserbetriebslage umgelenkt. In dieser Lage des Förderschlauches 5 lässt sich das Kransilo für eine weitere Beschickung und zum Abstellen auf den Boden einfacher manipulieren.
The crane silo further consists of a reversible lifting device 35 for the delivery hose 5, with the latter is raised in the hanging state from the operating position to a non-operating position so as not to be trapped when parking the crane silo on the ground can.
The lifting device 35 consists of a pivotable about a horizontal axis pivot bracket 41 which is secured to the shaft 19 of the actuator 14 opposite end of the frame 11 on the rotatable shaft formed as a rod 17. The pivot bracket 41 is formed by two opposing angled legs 42, 43, wherein at the free ends of the legs 43 a connecting them freely rotatable roller 44 is mounted, which lifts the hanging conveyor hose 5 when lifting the pivot bracket 41 from the operating position, so that it rests on the roller 44. The Fig. 1 . 2 and 3 show the position of the lifting device 35 in which the delivery hose 5 is lifted upwards. The operation of the lifting device 35 is effected by a connected to the shaft 17 of the pivot bracket 41 crank 45. Here, the located between the metering bar 12, 13 conveying hose 5 is detected by the roller 44 and the in Fig. 1 shown lower Dosierbalken 13 to resp. lying on the roller 44 upwardly deflected into a shutdown position. In this position of the delivery hose 5, the crane silo can be more easily manipulated for further loading and parking on the ground.

In den Fig. 6 und 7 ist ein Kransilo 1 mit einer im trichterförmigen unteren Behälterbereich wirkenden Räumvorrichtung 51 dargestellt. Diese soll zum Abbau von möglichen Brücken resp. zur vollständigen Entleerung des Behälters 2 dienen, um -im Sinne einer Verbesserung der Bausubstanz - über den Förderschlauch 5 vermehrt zähflüssige Baustoffe einer Schalung zuzuführen, unter Nutzung einer günstigeren Zugänglichkeit durch den flexiblen Förderschlauch 5.
Grundsätzlich macht der Einsatz einer Räumvorrichtung 51 auch Sinn bei einer Verarbeitung von Baustoffen mittels Kransilo ohne Förderschlauch 5, da derartige Kransilos an den zumindest unteren trichterförmigen Bereich des Behälters anschliessend einen Klappen- oder Schiebeverschluss aufweisen, über dem die zähfliessende Masse durch seitlichen Druck der Trichterform verdichtet wird. Betroffen sind Kransilos mit einem zylindrischen oberen Behälterbereich der sich zur Entleerungsöffnung hin trichterförmig verengt, oder Kransilos mit mehreckigem Behälterquerschnittsform gemäss CH 285 831 A5 , oder solche Kransilos die von oben bis unten kegelförmig sich verengend ausgebildet sind.
Um die Entleerung des Behälters 2 weiter optimieren zu können, ist es zweckmässig, eine weitere Räumvorrichtung 51 an der trichterförmigen Innenwand resp. den Innenwänden des Behälters vorzusehen, die gegenüber der ersten Räumvorrichtung 51 angeordnet ist, wobei die Schiebebewegung beider Räumvorrichtungen 51 vorteilhaft gekoppelt werden.
Die Räumvorrichtung 51 hat eine Wirkung entlang der zur Entleerungsöffnung 3 hin reichenden trichterförmigen Innenwand des Behälters 2 und wird ausserhalb des
Behälters 2 angetrieben. Die Räumvorrichtung 51 weist einen auf die Baustoffe räumend einwirkenden Schieber 52 auf, der an einem Ende eines parallel zu den Mantellinien des unteren Behälterbereichs hin und zurück antreibbaren Stössel 53 befestigt ist. Der in Fig. 7 dargestellte Schieber 52 weist eine gegen die Entleerungsöffnung 3 gerichtete offene V-Form auf; selbstverständlich eignen sich auch andere Schieberformen, die die Brücken der Baustoffe zerstören und eine Förderung bewirken. Der Stössel 53 ist an dem vom Schieber 52 abgewandten Ende an einem in den Behälter 2 ragenden Hebelende eines ausserhalb des Behälters 2 gelagerten Doppelhebels 54 angelenkt, dessen gegenüberliegendes Hebelende mit einem Ende eines Lenkers 55 gekuppelt ist. Der Doppelhebel 54 ist an einem mit dem Behälter 2 verbundenen Lagerbock 56 schwenkbar gelagert. Die aus dem Doppelhebel 54 und Lenker 55 gebildete Hebelanordnung weist einen an der Betätigungswelle 19 der Hebelgetriebe 27, 28 befestigten Hebelarm 57 auf, an dem das weitere Ende des Lenkers 55 angelenkt ist. Daraus entsteht, dass bei der Betätigung der Dosiervorrichtung 8 resp. der Dosierbalken 12, 13 zum Durchfluss des Baustoffes auch eine Stossbewegung des Schiebers 52 ausgeführt wird.
Selbstverständlich könnten die Schieberbewegungen mit einem von der Dosiervorrichtung 8 getrennten Betätigungsstock ausgeführt werden.
In the 6 and 7 a crane silo 1 is shown with a clearing device 51 acting in the funnel-shaped lower container area. This should reduce potential Bridges resp. serve for complete emptying of the container 2, in order to improve the building substance - via the delivery hose 5 increasingly supplied viscous building materials formwork, using a more favorable accessibility through the flexible delivery hose fifth
In principle, the use of a clearing device 51 also makes sense in the processing of building materials by means of crane silo without conveying hose 5, since such crane silos to the at least lower funnel-shaped portion of the container then a flap or sliding closure over which compresses the viscous mass by lateral pressure of the funnel shape becomes. Affected are crane silos with a cylindrical upper container area which narrows in a funnel shape toward the discharge opening, or kranilos with a polygonal container cross-sectional shape according to FIG CH 285 831 A5 , or such Kransilos are conically tapered from top to bottom.
In order to optimize the emptying of the container 2 further, it is expedient, respectively, a further clearing device 51 to the funnel-shaped inner wall. provide the inner walls of the container, which is arranged opposite the first clearing device 51, wherein the sliding movement of both clearing devices 51 are advantageously coupled.
The clearing device 51 has an effect along the funnel-shaped inner wall of the container 2 extending to the discharge opening 3 and is outside the container
Container 2 driven. The reaming device 51 has a slider 52 acting on the building materials, which is attached to one end of a ram 53, which can be driven back and forth in parallel with the generatrices of the lower container region. The in Fig. 7 illustrated slide 52 has a directed against the discharge opening 3 open V-shape; Of course, other forms of slide are suitable, which destroy the bridges of the building materials and cause a promotion. The plunger 53 is at the end remote from the slider 52 at an in hinged to the container 2 lever end of a mounted outside the container 2 double lever 54, whose opposite end of the lever is coupled to one end of a link 55. The double lever 54 is pivotally mounted on a bearing block 56 connected to the container 2. The lever assembly formed from the double lever 54 and link 55 has a lever arm 57 attached to the actuating shaft 19 of the lever mechanism 27, 28, to which the further end of the link 55 is articulated. It follows that when operating the metering device 8 resp. the metering bar 12, 13 for the flow of the building material and a shock movement of the slider 52 is executed.
Of course, the slide movements could be performed with a separate from the metering 8 operating stick.

Für den Fall einer schlauchlosen Entnahme von Baustoffen aus dem Behälter könnte die Räumvorrichtung 51 mit der Betätigungseinrichtung einer Verschlussvorrichtung oder mit einer separaten Betätigungseinrichtung verbunden sein.In the case of a tubeless removal of building materials from the container, the clearing device 51 could be connected to the actuator of a closure device or with a separate actuator.

Die Fig. 8 und 9 zeigen eine an ein herkömmliches Kransilo anbaubare Dosiervorrichtung 8. Diese wird bei geöffneter Verschlussvorrichtung an der Entleerungsöffnung des Kransilos zwischen die Verschlussklappen eingespannt. Hierzu sind an dem Gestell 11 zwei Befestigungsbleche 61 vorgesehen, an denen die Dosiervorrichtung 8 an der Verschlussvorrichtung aufgehängt ist. Der Förderschlauch 5 wird an einem mit den Befestigungsblechen 61 verbundenen Rohrstutzen 63 mit einer Bride 6 festgeklemmt. Die Dosierung der entnommenen Masse wird, wie schon oben beschrieben, durch die Bewegung der Dosierbalken 12, 13 gesteuert, die mit dem Hebelgetriebe 27, 28 verbunden sind. Damit ein störungsfreier Einlauf der Masse in den Förderschlauch 5 erfolgen kann, sind seitlich zum Rohrstutzen hin abfallende Leitbleche 60 vorgesehen, die ein unerwünschtes Austreten der schüttfähigen Baustoffe verhindern. Zur Montage der Dosiervorrichtung an dem Kransilo resp. der Verschlussvorrichtung sind seitliche Traggriffe 62 an den Befestigungsblechen 61 vorgesehen.The 8 and 9 show a can be attached to a conventional crane silo metering 8. This is clamped with the shutter open at the emptying opening of the crane silo between the flaps. For this purpose, two mounting plates 61 are provided on the frame 11, on which the metering device 8 is suspended from the closure device. The delivery hose 5 is clamped to a pipe socket 63 connected to the mounting plates 61 with a bridge 6. The dosage of the extracted mass is, as already described above, controlled by the movement of the Dosierbalken 12, 13, which are connected to the lever mechanism 27, 28. Thus, a trouble-free inlet of the mass can be made in the delivery hose 5, laterally sloping baffles 60 are provided to the pipe stub, which is an undesirable escape of pourable building materials prevent. For mounting the metering device on the crane silo resp. the closure device lateral carrying handles 62 are provided on the mounting plates 61.
