Diese eine Verbesserungsmassnahme gestattet eine vorzügliche und sichere Bedienbarkeit, ein geringeres Konstruktionsgewicht als bei den bekannten Kransilos gleicher Aufnahmekapazität, einfachere Fertigungsmethoden, eine verbesserte Zugänglichkeit zu den Einzelteilen zum Zweck der Reinigung und des Unterhalts.This one improvement measure allows excellent and safe operation, a lower design weight than in the known crane silos same capacity, simpler manufacturing methods, improved accessibility to the items for the purpose of cleaning and maintenance.
Vorteilhaft sind die schildförmigen Tragelemente an dem Behälter sich gegenüberliegend angeordnet und mit Letzterem und dem Rahmenteil verbunden, wodurch eine stabile Standfestigkeit, geringere Raumverbauung und eine hohe Steifigkeit der verbundenen Teile erreicht wird. Behälter und Rahmenteil des Traggestells bilden mit den schildförmigen Tragelementen relativ lange Verbindungsstrecken resp. Schweissnähte , die zur kompakten Einheit eines Kransilos führen.Advantageously, the shield-shaped support members are arranged on the container opposite and connected to the latter and the frame part, whereby a stable stability, reduced space and a high rigidity of the connected parts is achieved. Container and frame part of the support frame form with the shield-shaped support elements relatively long connecting sections resp. Welding seams that lead to the compact unit of a crane silo.
Die hochstehenden Tragelemente können rechteckig oder trapezförmig ausgebildet sein, um die Verbindung mit dem oberen Behälterabschnitt oder dem Rahmenteil weiter optimieren zu können.The upstanding support elements may be rectangular or trapezoidal in order to further optimize the connection with the upper container portion or the frame part can.
Im Sinne einer Gewichtsoptimierung des Kransilos ist das stehende Tragelement mit einer Aussparung resp. Öffnung ausgebildet, die auch die Zugänglichkeit zu den beweglichen Teilen erleichtert.In the sense of weight optimization of the crane silo is the standing support element with a recess resp. Opening formed, which also facilitates accessibility to the moving parts.
Der Rahmenteil ist vorzugsweise ringförmig ausgebildet resp. an die Querschnittsform des oberen Behälterabschnitts angepasst, sodass eine Neigungslage in hängendem Zustand des Kransilos verhindert wird. Der Rahmenteil kann aus einem rohrförmigen Profil gebildet sein.The frame part is preferably annular, respectively. adapted to the cross-sectional shape of the upper container portion, so that a tilted position in the suspended state of the crane silo is prevented. The frame part may be formed from a tubular profile.
Der Anteil der Tragelemente an dem Umfang des oberen Behälterabschnitts bzw. am Umfang des kreisförmigen Rahmenteils kann etwa 60° betragen.The proportion of the support elements on the circumference of the upper container portion or at the periphery of the circular frame part may be about 60 °.
Bei einem Kransilo mit einer der Verschlussvorrichtung aus einer Ausserbetriebsstellung in eine Betriebsstellung zustellbaren Auslaufschurre, in der sie der Verschlussvorrichtung förderwirksam zugeordnet und in einer schräg nach unten gerichteten Austragslage angeordnet ist, ist es vorteilhaft, wenn die schildförmigen resp. rechteckigen oder trapezförmigen Tragelemente zur schwenkbaren Lagerung der an Hebeln befestigten Auslaufschurre ausgebildet sind und dass der Rahmenteil zur Verschwenk- bzw. Zustellbarkeit der Auslaufschurre an die Verschlussvorrichtung eine Ausnehmung aufweist. Die Ausnehmung an dem Rahmenteil vermag wenigstens teilweise das Gewicht der seitlich aufgehängten oder in der Betriebsstellung angeordneten Auslaufschurre zu kompensieren.In a crane silo with one of the closure device from an inoperative position deliverable to an operating position outlet chute in which it is assigned to the closure device effective and arranged in an obliquely downward discharge position, it is advantageous if the shield-shaped resp. rectangular or trapezoidal support elements for pivotally mounting the levers attached to the outlet chute are formed and that the frame part has a recess for pivoting or deliverability of the outlet chute to the closure device. The recess on the frame part can at least partially compensate for the weight of the laterally suspended or arranged in the operating position discharge chute.
Mit Rücksicht auf die Verschlussvorrichtung kann die Entleerungsöffnung des Behälters in Austragsrichtung betrachtet rechteckförmig ausgebildet sein und ion eine als Klappen-, Schieber- oder Schlauchverschluss ausgebildete Verschlussvorrichtrung münden, wodurch über der Entleerungsöffnung eine Brückenbildung der sich im Behälter befindenden Baustoffe verhindert wird und optimale Austragsverhältnisse geschaffen sind.With regard to the closure device, the emptying opening of the container in the discharge direction can be designed rectangular and ion open as a flap, slide or hose closure Verschlussvorrichtrung, whereby over the discharge opening bridging of the building materials located in the container is prevented and created optimal Austragsverhältnisse are.
Zweckmässigerweise entspricht die Förderbreite der Auslaufschurre wenigstens einer Auslaufbreite an der Verschlussvorrichtung.Conveniently, the conveying width of the outlet chute corresponds to at least one outlet width at the closure device.
Vorzugsweise ist bei einer einen Klappenverschluss aufweisenden Verschlussvorrichtung eine Schwenkachse einer Verschlussklappe parallel zur Längsseite der rechteckigen Entleerungsöffnung des Behälters angeordnet, sodass die Entleerungsöffnung optimal genutzt werden kann.Preferably, in the case of a closure device having a flap closure, a pivot axis of a closure flap is arranged parallel to the longitudinal side of the rectangular emptying opening of the container so that the emptying opening can be optimally utilized.
Vorteilhaft ist bei einem Kransilo mit einem zur Betätigung des Klappenverschlusses beidseits des Behälters angeordneten Hebelgetrieben eine Letztere verbindende gemeinsame Antriebswelle vorgesehen, die an den schildförmigen Tragelementen gelagert ist, wodurch die Hebelgetriebe und die Verschlussvorrichtung hinter den Tragelementen weitgehend geschützt sind.Advantageously, in a crane silo with a arranged for actuating the flap closure on both sides of the container lever drives a latter connecting common drive shaft is provided which is mounted on the shield-shaped support members, whereby the lever mechanism and the closure device are largely protected behind the support elements.
Es bietet sich daraus die zweckmässige Möglichkeit an, dass die Tragelemente jeweils in seitlichem Randabstand mit einem Lagerbock ausgebildet sind, in denen die Antriebswelle gelagert ist, sodass eine optimale Anordnung eines mit der Antriebswelle fest verbundenen Bedienungshebels vorgenommen werden kann.It therefore offers the appropriate possibility that the support elements are each formed in the lateral edge distance with a bearing block in which the drive shaft is mounted so that an optimal arrangement of a firmly connected to the drive shaft operating lever can be made.
Es ist hierzu und aus unfalltechnischer Sicht von Vorteil, wenn eine Seitenkante der schildförmigen Tragelemente mit einer nach innen gerichteten Biegekante ausgestattet ist, an der jeweils ein Lagerbock befestigt ist.It is for this purpose and from accident technical point of view advantageous if a side edge of the shield-shaped support elements is equipped with an inwardly directed bending edge, on each of which a bearing block is attached.
Hilfsweise kann der Behälter gegenüber von einer allfälligen Ausnehmung des Rahmenteils und/resp. zwischen den Tragelementen auf dem Rahmenteil abgestützt sein, wozu sich beispielsweise ein Stahlrohr eignet.In the alternative, the container can be compared with a possible recess of the frame part and / resp. supported between the support elements on the frame part be, for which, for example, a steel pipe is suitable.
