Description

Die Erfindung betrifft ein Lasthubsystem mit mindestens einer auf einem Hubrahmen gelagerten Seiltrommel für mehrere Hubseile, die je um Seilrollen einer Traverse und des Hubrahmens zu einem Festpunkt geführt sind.The invention relates to a load lifting system with at least one cable drum mounted on a lifting frame for a plurality of lifting cables, each of which is guided to a fixed point around pulleys of a traverse and the lifting frame.

Bei einem Lasthubsystem dieser Art nach der DE-PS 29 17 588 sind zum Heben und Senken der mit der Last verbundenen Traverse zwei Seiltrommeln für je ein Hubseil vorhanden. Diese Seilrollen sind koaxial zueinander angeordnet und können zum Wahren des Gleichlaufes miteinander verbunden sein. Zum Verhindern von Pendelbewegungen der Traverse ist eine Stabilisierungsseiltrommel vorhanden und über ein Getriebe antriebsmäßig mit der Hubseiltrommel verbunden. Von der Stabilisierungsseiltrommel führen Stabilisierungsseile über Seilrollen des Hubrahmens diagonal zu Seilrollen der Traverse, wo sie über Spann­und Dämpfungseinrichtungen zu Festpunkten geführt sind. Diese Spann- und Dämpfungseinrichtungen sind aufwendig und können nachgeben, so daß Pendelbewegungen der Traverse mit der Last nicht in gewollter Weise verhindert werden.In a load lifting system of this type according to DE-PS 29 17 588, two cable drums for each lifting cable are available for lifting and lowering the cross member connected to the load. These pulleys are arranged coaxially with each other and can be connected to each other to maintain synchronism. A stabilizing cable drum is available to prevent pendulum movements of the traverse and is connected to the lifting cable drum by means of a drive. From the stabilizing cable drum, stabilizing cables lead diagonally via pulleys of the lifting frame to pulleys of the traverse, where they are guided to fixed points via tensioning and damping devices. These tensioning and damping devices are complex and can yield, so that pendulum movements of the traverse with the load are not prevented in an intended manner.

Aufgabe der Erfindung ist es daher, ein Lasthubsystem der beschriebenen Art preiswerter und sicherer zu gestalten. Diese Aufgabe wird durch die Merkmale des Hauptanspruches gelöst. Die Hubseile sind zunächst senkrecht von der Seiltrommel zu den Seilrollen an inneren Längsträgern der Traverse geführt und übernehmen damit die Hub-Funktion. Die Seile sind sowohl bei angehobener als auch bei gesenkter Traverse senkrecht oder annähernd senkrecht zwischen Seiltrommel und Traverse geführt, so daß es keine großen Seilablenkungen an der Seiltrommel und den Seilrollen gibt. Die Hubseile werden dann nach Umlenkung um die waagerecht an der Traverse angeordneten Seilrollen zu senkrechten Seilrollen geführt, die etwa in der Mitte der Längs- und Querträger angeordnet sind. Von da aus werden die Hubseile schräg zu Seilrollen des Hubrahmens und wieder schräg zurück zu Festpunkten an der Traverse geführt. Der schräggeführte Bereich dieser Hubseile verhindert ein Pendeln und Drehen der Last und bildet gleichzeitig einen Flaschenzug. Da alle acht Seile in gleichem Maße geführt sind, gibt es keine unterschiedlichen Seillängungen, die durch nachgebende Vorrichtungen ausgeglichen werden müssen.The object of the invention is therefore to make a load lifting system of the type described cheaper and safer. This object is solved by the features of the main claim. The hoisting ropes are initially guided vertically from the rope drum to the rope pulleys on the inner longitudinal members of the traverse and thus take over the lifting function. The cables are guided vertically or approximately vertically between the cable drum and the crossbar, both when the crossbar is raised and when it is lowered, so that there are no large cable deflections on the cable drum and the pulleys. The lifting ropes are then after deflection to vertical to the rope pulleys arranged horizontally on the crossbar Rope pulleys guided, which are arranged approximately in the middle of the longitudinal and cross members. From there, the hoisting ropes are led diagonally to the pulleys of the lifting frame and diagonally back to fixed points on the crossbar. The inclined area of these hoisting ropes prevents the load from swinging and rotating and at the same time forms a pulley block. Since all eight ropes are routed to the same extent, there are no different rope lengths that have to be compensated for by flexible devices.

In weiterer Ausgestaltung der Erfindung sind die acht Hubseile in gegenläufigen Seilrillen nur einer Seiltrommel geführt, deren Seilablaufseite in der Längsmittenachse der Traverse angeordnet ist. Zum Ausgleichen von unterschiedlicher Seilstraffung bei der Montage können die Hubseile über Längennachstellvorrichtungen an den Festpunkten der Traverse befestigt sein. Da alle Hubseile stets gleich belastet werden, ist keine unterschiedliche Seillängung zu erwarten und ein späteres Nachstellen nicht erforderlich.In a further embodiment of the invention, the eight hoisting ropes are guided in opposite rope grooves in only one rope drum, the rope outlet side of which is arranged in the longitudinal center axis of the crossmember. To compensate for different rope tensioning during assembly, the lifting ropes can be attached to the fixed points of the crossbar via length adjustment devices. Since all hoisting ropes are always loaded equally, no different rope lengthening is to be expected and subsequent adjustment is not necessary.

In Fig. 1 ist zu erkennen, daß Pendelbewegungen quer zur Seiltrommel 1 durch die Hubseile 30 ,60; 40 und 50 verhindert werden. Sie führen nach der Umlenkung an den in Fig. 3 an den Ecken erkennbaren Seilrollen 33 und 63 bzw. 43 und 53 um die Seilrollen 34, 64, 44 und 54 in Traversenmitte hoch zu den Seilrollen 35, 65 sowie 45 und 55 unter dem Hubrahmen wieder herunter zu den Festpunkten 36, 66 und 46, 56 am Querträger 8T. Pendelbewegungen in Längsrichtung der Seiltrommel werden durch die in Fig. 2 erkennbaren schrägen Seile 10, 20, 70 und 80 verhindert, die von den mittleren Seilrollen 14, 24, 74 und 84 des Traversen-Längsträgers 67 um die oberen Seilrollen 15, 25, 75 und 85 wieder herunter zu den unteren Festpunkten 16, 26, 76 und 86 am Längsträger 6T geleitet werden.In Fig. 1 it can be seen that pendulum movements transverse to the cable drum 1 by the hoisting ropes 30, 60; 40 and 50 can be prevented. After the deflection on the rope pulleys 33 and 63 or 43 and 53 recognizable at the corners in FIG. 3 around the rope pulleys 34, 64, 44 and 54 in the middle of the crossbar to the rope pulleys 35, 65 and 45 and 55 under the lifting frame down to the fixed points 36, 66 and 46, 56 on the cross member 8T. Pendulum movements in the longitudinal direction of the rope drum are prevented by the inclined ropes 10, 20, 70 and 80 which can be seen in FIG and 85 back down to the lower fixed points 16, 26, 76 and 86 on the side member 6T.

In Fig. 2 sind in der Seiltrommel 1 entgegengesetzt gerichtete Pfeile eingetragen, die die gegenläufigen Seilrillen-Richtungen angeben. Das Seil 10 läuft vom höhenabhängigen Ablaufpunkt 11 von der Seiltrommel 1 ab und führt um die Seilrolle 12 am inneren Längsträger 7T der Traverse 5 um die Seilrolle 13, die in Fig. 3 als waagerechte Scheibe zu erkennen ist. Von dort führt das Seil 10 weiter um die in Fig. 2 erkennbare mittlere Seilrolle 14, von dort um die obere Seilrolle 15 und wieder zurück zum Festpunkt 16 an dem Längsträger 6T der Traverse 5. In analoger Weise sind alle anderen Hubseile auch geführt und bilden dabei den ohnehin erforderlichen Flaschenzug.In Fig. 2 opposite arrows are entered in the cable drum 1, which indicate the opposite directions of the cable groove. The rope 10 runs from the height-dependent run-off point 11 from the rope drum 1 and leads around the rope pulley 12 on the inner longitudinal member 7T of the crossmember 5 around the rope pulley 13, which can be seen in FIG. 3 as a horizontal disc. From there, the cable 10 continues around the middle cable pulley 14 shown in FIG. 2, from there around the upper cable pulley 15 and back again to the fixed point 16 on the longitudinal beam 6T of the traverse 5. In an analogous manner, all other lifting cables are also guided and formed the pulley required anyway.

Bei der erfindungsgemäßen Seilführung verändert sich der Einlaufwinkel an der Seiltrommel und an den Seilrollen 12 bis 82 am inneren unteren Längsträger 7T der Traverse 5 nur geringfügig, hervorgerufen durch Seilwanderungen auf der Seiltrommel 1, wie in Fig. 2 erkennbar. Diese Seilwanderung ist aber gering, so daß die Traverse 5 weit abgesenkt werden kann, ohne daß unzulässig große Seilablenkungen auftreten. Diese Erfindung erlaubt somit pendelfreie Lasttransporte mittels Seilführung auch bei größeren Hubhöhen.In the rope guide according to the invention, the entry angle on the rope drum and on the rope pulleys 12 to 82 on the inner lower longitudinal member 7T of the crossmember 5 changes only slightly, caused by rope migration on the rope drum 1, as can be seen in FIG. 2. This rope migration is small, however, so that the traverse 5 can be lowered far without excessive rope deflections occurring inadmissible. This invention thus allows pendulum-free load transport by means of a rope guide even with larger lifting heights.

Alle anderen Seilrollen sind in der idealen Lage zur Seilführung gelagert, so daß es keine Ablenkungen der Hubseile an den Seilrollen gibt. Die in den Fig. 1 und 2 erkennbaren Seilablenkungen über der Traverse 5 sind in Wirklichkeit nicht vorhanden und entstanden nur durch eine zeichnerische Vereinfachung, um die Zeichnung nicht durch eine versetzte Höhenanordnung der Seilrollen unübersichtlicher werden zu lassen.All other rope pulleys are in the ideal position for rope guidance so that there are no deflections of the hoisting ropes on the rope pulleys. The visible in Fig. 1 and 2 rope deflections above the crossmember 5 are in reality not available and only a simplification of the drawing, so as not to make the drawing more confusing due to an offset height arrangement of the pulleys.
