PATENTAMT.PATENT OFFICE.
Bei elektrisch betriebenen Laufkranen mit hoher Fahrgeschwindigkeit macht sich der Übelstand bemerkbar, daß bei schnellem Fahren von Lasten, sei es durch Verlangsamung der Fahrt oder durch plötzliches Halten, die Last in größere Schwankungen gerät. Zur Beseitigung dieses Übelstandes ist man bisher dazu übergegangen, bei derartigen Hebezeugen die Last starr zu führen, so daß die Schwanklingen durch ein besonderes, von der Laufkatze herunterhängendes Gerüst aufgenommen wurden. Diese Einrichtung hat jedoch wieder den Nachteil, daß die an der Laufkatze befindlichen starren Führungsgerüste in den Arbeitsraum hineinragen und sehr störend wirken, indem die Werkstätten für die Durchfahrt dieser Führungsgerüste freigehalten werden müssen. Es kommt vor, daß diese Führungen an irgendwelche in der Werkstätte lagernde Gegenstände anstoßen, wodurch alsdann unliebsame Störungen entstehen.In the case of electrically operated overhead traveling cranes with high travel speed, the Objection noticeable when driving loads at high speed, be it by slowing down the Or by suddenly stopping, the load fluctuates significantly. For elimination this inconvenience has so far been passed over to such hoists Load rigidly to guide, so that the wobbly blades by a special, from the trolley hanging scaffolding were added. However, this facility has again the disadvantage that the rigid guide frames located on the trolley in the Work space protrude and have a very annoying effect, leaving the workshops for the passage this guide framework must be kept free. It happens that these tours are given to someone in the workshop bump into stored objects, which then causes unpleasant disturbances.
Die starre Führung der Lasten ist besonders wertvoll beim Transport von flüssigem Eisen mittels der Laufkrane, wie solche in neuerer Zeit häufig vorkommen in Form von sogenannten Gießlaufkranen für Martin werke. Mit diesen Kranen werden Pfannen mit flüssigem Inhalt von einer Gießgrube zur anderen gefahren und muß die Pfanne auf einige Millimeter genau über dem Eingang eingestellt werden können.The rigid guidance of the loads is particularly valuable when transporting liquids Iron by means of the overhead traveling cranes, as these have frequently occurred in recent times in the form of so-called pouring cranes for Martin werke. With these cranes, pans are made with liquid contents from one casting pit to another and must open the pan can be adjusted just a few millimeters above the entrance.
Gemäß der vorliegenden Erfindung werden nun unter Vermeidung des vorstehend erwähnten starren Führungsgerüstes Verspannungsseile angeordnet, welche vom Angriffspunkte des Tragseiles an der Last ausgehend nach dem Hebezeuge hin divergieren und dort auf besondere Trommeln aufgewickelt werden, so daß sie sich mit den Tragseilen gleichzeitig auf- und abwickeln. Die Spannseile wirken als Pendelschutzseile und verhindern ein Schwanken der Last.In accordance with the present invention, avoiding the aforementioned rigid guide frame tensioning cables arranged, which from the points of attack of the carrying rope on the load diverge towards the hoist and there wound onto special drums so that they wind up and unwind with the suspension cables at the same time. The tension ropes act as pendulum protection ropes and prevent the load from swaying.
In der beiliegenden Zeichnung ist als Ausführungsbeispiel die neue Anordnung für einen Laufkran in Fig. 1 und 2 in Seiten- und Stirnansicht dargestellt. Die Last wird in bekannter Weise an dem Lastseil α unter Benutzung bekannter Mittel aufgehängt. Die untere Ketten- oder Seilrolle b ist durch Pendelschutzseile c mit dem Gestell der Laufkatze verbunden, derart, daß an letzterer Ausleger dd angeordnet sind, welche an ihren äußersten Enden Rollen- tragen, über welche die Pendelschutzseile nach einer Aufwickelvorrichtung g. geführt werden.In the accompanying drawing, the new arrangement for an overhead traveling crane in FIGS. 1 and 2 is shown in side and front view as an exemplary embodiment. The load is suspended from the load rope α in a known manner using known means. The lower chain or rope pulley b is connected to the frame of the trolley by means of pendulum protection ropes c , in such a way that arms dd are arranged on the latter, which carry rollers at their outermost ends, over which the pendulum protection ropes after a winding device g. be guided.
