Description

Die Erfindung betrifft eine Hängekupplung an Hubvorrichtungen, insb. für das Aufnehmen und Absetzen von Wärme-Isolierhauben von und über Walzdrahtbunde.The invention relates to a hanging coupling on lifting devices, esp. for picking up and setting down heat insulation hoods from and above Wire bundles.

Wärmeisolierhauben, wie sie hinter kontinuierlichen Hochleistungs-Walzdrahtstraße verwendet werden, um die, aus aufeinanderliegenden Drahtschlingen in schneller Folge gebildeten, noch heißen Drahtbunde vor deren Weitertransport isolierend abzudecken, wurden bisher von Kranlaufkatzen oder ähnlichen Hubeinrichtungen mit Hilfe der, bei diesen üblichen Hängegeschirre erfaßt und gekuppelt und dann über die Drahtbunde abgesenkt, und anschließend, nach Entkupplung von dem Geschirr, weitertransportiert. Der Kuppel- bzw. Entkupplungsvorgang der Wärmeisolierhauben mit dem Hängegeschirr erforderte dabei Erfahrung des Bedienungspersonals und auch verhältnismäßig viel Zeit, da die Oberseite der Wärmeisolierhauben, je nach Konstruktion und Arbeitsweise der Einrichtungen für die Bundbildung mehr oder weniger gut zugänglich ist und auch die Strahlungshitze der heißen Bunde das Arbeiten erschwert.Thermal insulation hoods, such as those behind continuous high-performance wire rod mills used to make that out of one another Wire loops in quick succession, still hot wire bundles to isolate before transporting them, have been used by Crane trolleys or similar lifting devices with the help of these usual harnesses gripped and coupled and then over the bundles of wire lowered, and then, after uncoupling the dishes, transported on. The coupling or uncoupling process the thermal insulation hood with the hanging gear required Experience of the operating personnel and also relatively much Time since the top of the heat insulation hood, depending on the construction and functioning of the institutions for federal formation more or less accessible and also the radiant heat of the hot Bunde makes working difficult.

Der Erfindung liegt die Aufgabe zugrunde, diese Schwierigkeiten zu beseitigen und auch den Zeit- und Personalaufwand bei der Kupplung und Entkupplung des Hängegeschirrs mit den Wärmeisolierhauben zu verringern. The object of the invention is to overcome these difficulties eliminate and also the time and manpower in the clutch and uncoupling of the hanging gear with the heat insulation hoods reduce.

Diese Aufgabe wird dadurch gelöst, daß, an jeweils ein Ende einer Traverse doppelarmige Hebelpaare spiegelbildlich zueinander verschwenkbar angelenkt sind, deren eines Hebelarmpaar oberhalb der Traverse über Lenkerstangen mit der Hubeinrichtung verbunden ist, und deren anderes Hebelarmpaar, unterhalb der Traverse hakenförmige Enden aufweist, die durch eine, vom Hub der Lenkerstangen auf das Hebelpaar übertragenen Zugbewegung aufeinander zugeschwenkt, mit an der Oberseite der Wärmeisolierhaube angeordneten Tragansätzen kuppelbar sind, und daß auf der Traverse und dem oberen Hebelarmpaar jeweils, einander gegenüberliegend elektrische Zugmagnete und, diesen zugeordneten Anker angeordnet sind, die in Einschalt-Zugposition das obere Hebelarmpaar mit der Traverse schwenkverriegeln und dabei die hakenförmigen Enden des unteren Hebelarmpaares gegenüber den Tragansätzen der Wärmeisolierhaube außer Kuppelposition halten.This object is achieved in that at one end each Traverse double-armed lever pairs can be pivoted to each other in mirror image are articulated, one of a pair of lever arms above the Traverse is connected to the lifting device via handlebars, and their other pair of lever arms, hook-shaped below the crossbar Has ends by one, from the stroke of the handlebars to the Lever pair transmitted train movement swiveled towards each other, with support lugs arranged on the top of the heat insulation hood are detachable, and that on the crossbar and the upper pair of lever arms opposite each other electric traction magnets and, these associated anchors are arranged in the switch-on pull position lock the upper pair of lever arms with the crossbar and opposite the hook-shaped ends of the lower pair of lever arms the carrying lugs of the thermal insulation hood out of the coupling position hold.

Wie die Erfindung weiter vorsieht können an der Unterseite der Traverse und der Oberseite der Wärmeisolierhaube Ausrichtelemente angeordnet sein, die bei Aufsetzen der Traverse auf die Wärmeisolierhaube lösbar ineinandergreifen. Diese Ausrichtelemente können aus, an der Unterseite der Traverse angeordneten, nach unten gerichteten keilförmigen Ansätzen und entsprechenden, nach oben offenen Keilvertiefungen sowie ggfs. seitlichen trichterförmig geneigten Führungsblechen auf der Oberseite der Wärmeisolierhaube bestehen.As the invention further provides at the bottom of the Traverse and the top of the thermal insulation hood alignment elements be arranged when the crossbar is placed on the heat insulation hood releasably interlock. These alignment elements can from, arranged on the underside of the traverse, directed downwards wedge-shaped approaches and corresponding, open to the top Wedge depressions and, if necessary, inclined funnel-shaped sides There are guide plates on the top of the heat insulation hood.

Mit dieser erfindungsgemäßen Anordnung und Ausbildung der Hängekupplung für Wärmeisolierhauben wird die Möglichkeit geschaffen, die Hängekupplung, nachdem diese über die Wärmeisolierhaube auf deren Oberseite abgesenkt wurde, ohne zusätzliche Bedienungshandgriffe außer dem Ein- bzw. Ausschalten der Zugmagnete, auf die Oberseite der Wärmeisolierhaube auszurichten, mit dieser zu kuppeln und wieder anzuheben. With this arrangement and design of the suspension coupling according to the invention the possibility is created for thermal insulation hoods Suspension coupling after this over the thermal insulation hood on the Top was lowered without additional operating handles except for switching the pull magnets on and off on the top align the thermal insulation hood, couple with it and again to raise.

Die Erfindung wird anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigen

Fig. 1
die Hängekupplung von der Seite gesehen in geöffneter Position und

die Hängekupplung nach Fig. 1 in der Kupplungsposition.
The invention is explained in more detail with reference to the embodiment shown in the drawing. Show in the drawing
Fig. 1
the suspension coupling seen from the side in the open position and
Fig. 2
1 in the coupling position.

Wie aus Fig. 1 zu ersehen, sind an beiden Enden einer Traverse 1 die zweiarmigen Hebel 2 eines Hebelpaares mit Lenklagern 3 angelenkt. Die Enden des oberen Hebelarmpaares 2a, oberhalb der Traverse 1 sind gelenkig über Lenkerstangen 4 mit der Hubeinrichtung 5 verbunden. Die Enden des unteren Hebelarmpaares 2b sind hakenförmig ausgebildet. Ihnen liegen Tragansätze 6a gegenüber, die an der Wärmeisolierhaube 6 angeordnet sind.As can be seen from FIG. 1, a crossbar 1 is located at both ends the two-armed levers 2 of a pair of levers articulated with steering bearings 3. The ends of the upper pair of lever arms 2a, above the crossbar 1 are articulated via handlebars 4 with the lifting device 5 connected. The ends of the lower pair of lever arms 2b are hook-shaped educated. You are opposite approaches 6a, which on the Thermal insulation hood 6 are arranged.

Auf der Oberseite der Traverse 1 (vgl. Fig 2) sind Zugmagnete 7 angeordnet, denen unterhalb des oberen Hebelarmpaares 2a angeordnete Anker 8 zugeordnet sind. Ferner sind im Bereich der Tragansätze 6a auf der Oberseite der Wärmeisolierhaube 6 Auflagerasten 6b für das Auflegen der Traverse 1 und seitliche, trichterförmig geneigte Führungsbleche 10 sowie oben offene Keilvertiefungen 9 vorgesehen.Pull magnets 7 are on the top of the cross member 1 (see FIG. 2) arranged, which are arranged below the upper pair of lever arms 2a Anchor 8 are assigned. Furthermore, in the area of the support lugs 6a on the top of the heat insulation hood 6 support latches 6b for the Place the crossbar 1 and lateral, funnel-shaped incline Guide plates 10 and wedge depressions 9 open at the top are provided.

Die Hängekupplung arbeitet in der Weise, daß sie mit Hilfe der Hubeinrichtung 5 in der in Fig. 1 wiedergegebenen Position der Doppelarmhebel 2 bei eingeschalteten Zugmagneten 7 auf die Oberseite der Wärmeisolierhaube 6 abgesenkt wird, wobei sich die Traverse auf die Auflagerasten 6b an der Oberseite der Wärmeisolierhaube 6 auflegt. Die hakenförmigen Enden des unteren Hebelarmpaares 2b liegen dabei den Tragansätzen 6a gegenüber. Die Ausrichtung der Traverse 1 in diese Position erfolgt über die erwähnten Führungsbleche 9 bzw. Keilvertiefungen 10, in entsprechende (hier nicht dargestellte) Elemente an Traverse 1 eingreifen. Nach Ausschalten der Zugmagnete 7 und Anziehen der Hebelvorrichtung 5 im Hubsinne schwenken die Doppelarmhebel 2 in die in Fig. 2 wiedergegebene Position, wobei die Enden der unteren Hebelarmpaare 2b die Tragansätze 6a erfassen und damit die Kupplung zwischen Traverse 1 und Wärmeisolierhaube 6 vornehmen. Nach dem späteren Absetzen der Wärmeisolierhaube 6 bzw. auf einen, hier nicht dargestellten Rollgang, bewegen sich die Doppelarmhebel durch den sog. Schlaffseileffekt wieder in die Fig. 1 dargestellte Position zueinander und können dann durch Einschalten der Magnete 7 in dieser Position festgehalten werden, um einen weiteren Kuppelvorgang einzuleiten. The hitch works in such a way that it works with the help of Lifting device 5 in the position shown in FIG Double arm lever 2 with the pull magnet 7 switched on on the top the heat insulation hood 6 is lowered, the crossbar opening the bearing catches 6b on the top of the heat insulation hood 6 hangs up. The hook-shaped ends of the lower pair of lever arms 2b lie opposite the support lugs 6a. The orientation of the Traverse 1 in this position takes place via the guide plates mentioned 9 or wedge depressions 10, in corresponding (not here shown) engage elements on crossbar 1. After switching off the pull magnet 7 and tightening the lever device 5 in the lifting direction pivot the double-arm levers 2 into the position shown in FIG. 2, the ends of the lower pairs of lever arms 2b being the support lugs 6a and thus the coupling between the crossbar 1 and the heat insulation hood 6. After the thermal insulation hood has been removed later 6 or on a roller table, not shown here, the double arm levers move through the so-called slack rope effect back to each other in the position shown in FIG. 1 and can then held in this position by switching on the magnets 7 to initiate another coupling process.
