Abstract

The load raising and lowering arrangement designed for safety in the case of cable breakage, has two parallel winding drums (A, B) from which two cables (7, 8) are unwound to lower the load. The load is supported by a hook attached to a cage with two pulleys (9, 10) mounted inside, the upper one (10) for one cable (8) and the lower one (9) for the other cable (7). Each drum consists of two drum units (1, 2 and 3, 4) and the end of one cable (eg. 7) is unwound from a drum (3) one end and wound onto a drum (2) at the other end of the other double drum, while passing around its pulley (9). Thus the two cable loops cross each other diagonally.

Sicherheitshubwerk für mehrsträngige SeilaufhängungenSafety hoist for multi-strand rope suspensions

Die Erfindung betrifft ein Sicherheitshubwerk für mehrsträngige Seilaufhängungen mit zwei achsparallel angeordneten und einzeln angetriebenen Hubwerken zum Aufwickeln der Seile und den die Last tragenden axial übereinanderliegenden Umlenkrollen.The invention relates to a safety hoist for multi-strand rope suspensions with two axially parallel and individually arranged driven hoists for winding up the ropes and the axially superimposed deflection pulleys carrying the load.

Es sind Sicherheitshubwerke bekannt, bei denen zur Minderung der Bauhöhe die Seile von den Hubwerken über Umlenkrollen mit unterseil edlichem Durchmesser geführt sind, wobei einer Umlenkrolle mit großem Durchmesser der Oberflasche eine Umlenkrolle mit kleinem Durchmesser der Unterflasche und umgekehrt gegenüber liegen und die Seile gegenläufig sich kreuzend geführt sind, indem das Seil eines Hubwerks über die Seilrollen mit großem Durchmesser und das Seil des anderen Hubwerks über Umlenkrollen mit kleinem Durchmesser geführt sind. Eine derartige Anordnung gewährleistet zwar bei Ausfall eines Hubwerkes oder eines Seils, daß die Last von dem anderen Hubwerk oder Seil gehalten wird, ein Anheben oder Absenken der Last jedoch nicht mehr gewährleistet ist. Im übrigen ist diese Anordnung sehr aufwendig.There are safety hoists known in which the ropes from the hoists via pulleys to reduce the overall height untereil edischem diameter are guided, with a pulley with a large diameter of the upper block a pulley with a small diameter of the lower block and vice versa are opposite and the ropes are crossed in opposite directions by the rope of a hoist over the pulleys with a large diameter and the rope of the other hoist are guided over pulleys with a small diameter. Such a one Arrangement ensures that in the event of failure of a hoist or a rope that the load from the other hoist or rope is held, but lifting or lowering of the load is no longer guaranteed. Otherwise, this arrangement is very expensive.

Die Erfindung hat sich zur Aufgabe gestellt, diese Nachteile zu beseitigen und ein Sicherheitshubwerk der eingangs genann-The invention has set itself the task of eliminating these disadvantages and a safety lifting mechanism of the aforementioned

ten Art zu schaffen, das einerseits die Last an zwei oder mehreren Rollen trägt, andererseits bei Ausfall eines Hubwerks oder eines Seils die Last sowohl anheben als auch absenken kann.th type of creating the one hand the load on two or more On the other hand, if a hoist or a rope fails, it can both raise and lower the load.

Nach der Erfindung wird diese Aufgabe dadurch gelöst, daß die Hubwerke aus zwei gleichachsig angeordneten Hubtrommeln bestehen und die von außen nach innen auf den Trommeln auf- und ablaufenden Seile diagonal von der einen Trommel des einen Hubwerks auf die andere Trommel des anderen Hubwerks sich kreuzend über Umlenkrollen geführt sind, deren Achsen in einem Winkel
von ca. 90° zueinander liegen.
According to the invention, this object is achieved in that the hoists consist of two coaxially arranged hoist drums and the ropes running up and down on the drums from the outside to the inside, crossing diagonally from one drum of one hoist to the other drum of the other hoist Deflection rollers are guided, the axes of which are at an angle
90 ° to each other.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing shown.

Die Hubwerke A und B bestehen aus den beiden miteinander verbundenen Hubtrommeln 1, 2 und 3, 4-, wobei die beiden, je mit
einem eigenen Antrieb 5 und 6 ausgestatteten Hubwerke A und B achsparallel und die Hubtrommeln 1, 2 und 3, 4- axial zueinander angeordnet sind. Auf den Hubtrommeln 1 bis 4- sind die Seile 7 und 8 von außen nach innen laufend und auf den Hubwerken A, B gegenläufig auf- und abwickelnd angeordnet, die Seile 7> 8 auf den Hubtrommeln 1, 2 bzw. 3, 4- sich gleichzeitig und
gleichmäßig zu- und voneinander bewegen. Dabei ist das Seil 7 von der Trommel 2 diagonal über eine Umlenkrolle 9 zur Hubtrommel 3, und das Seil 8 diagonal von der Hubtrommel 1 über
eine Umlenkrolle 10 zur Hubtrommel 4- geführt. Um ein zwangsfreies Führen der Seile 7» 8 zu ermöglichen,sind in der senkrechten Schwerachse die Achsen der Umlenkrollen 9, 10 zuein-
The hoists A and B consist of the two interconnected hoist drums 1, 2 and 3, 4-, the two, each with
their own drive 5 and 6 equipped hoists A and B axially parallel and the hoist drums 1, 2 and 3, 4- are arranged axially to one another. On the hoist drums 1 to 4-, the ropes 7 and 8 run from the outside to the inside and wind and unwind in opposite directions on the hoists A, B, the ropes 7> 8 on the hoist drums 1, 2 or 3, 4- themselves at the same time and
move evenly towards and away from each other. The rope 7 is diagonally from the drum 2 over a pulley 9 to the lifting drum 3, and the rope 8 is diagonally from the lifting drum 1 over
a pulley 10 to the lifting drum 4- out. In order to enable the ropes 7 »8 to be guided freely, the axes of the deflection pulleys 9, 10 are to be aligned in the vertical center of gravity.

ander versetzt, vorteilhaft in einem Winkel von ca. 90°. Der Seilausgleich kann in die Hubtrommel oder in die untere Umlenkrolle gelegt sein. Dabei sind die Hubtrommeln 1 bis 4 so ausgebildet, daß bei einem Ausfall eines Hubwerks bei abgesenkter Last das andere Hubwerk die Seile aufwickeln kann, da die Länge der einzelnen Hubtrommeln so bemessen ist, daß die gesamte Seillänge aufgewickelt werden kann. Andererseits ist bei Ausfall eines Hubwerks und angehobener Last auf dem anderen Hubwerk noch so viel Seil auf den Hubtrommeln vorhanden, daß eine volle Senkbewegung ausgeführt werden kann. In beiden Fällen wird die Last von beiden Seilen gehalten und immer im Schwerpunkt geführt.offset to the other, advantageously at an angle of approx. 90 °. Of the Cable compensation can be placed in the lifting drum or in the lower pulley. The lifting drums 1 to 4 are designed so that that in the event of failure of a hoist when the load is lowered, the other hoist can wind up the ropes, since the length of the individual lifting drums is dimensioned so that the entire length of the rope can be wound up. On the other hand is in the event of failure a hoist and a raised load on the other hoist still so much rope on the hoist drums that one full lowering movement can be performed. In both cases the load is held by both ropes and always in the center of gravity guided.
