Abstract

The installation assembly for the installation of electrodes, used for the production of electric steel, has a threaded sleeve (4) with a sufficient length through the cover plate (2) for screw bonding an electrode section with a nipple. The movement length is limited by a lock (10) which prevents detachment.

Description

Die Erfindung betrifft einen Montagehilfsmittel, bestehend aus einer Gewindehülse mit einem Haken, die beweglich in dem Montagehilfsmittel angeordnet sind, wobei das Montagehilfsmittel mindestens aus einer Deckplatte und einer bügelartig daran befestigten Hebeöse besteht und die Gewindehülse eine Wegstrecke ausführen kann, insbesondere für die Verwendung bei der Elektrodenstrang-Montage aus miteinander verschraubten Elektrodenabschnitten.The The invention relates to an assembly aid consisting of a threaded sleeve with a hook that is movably arranged in the mounting tool are, wherein the assembly aid at least from a cover plate and a bow-shaped attached lifting eye exists and the threaded sleeve one Run route can, especially for the Use in the electrode assembly from screwed together Electrode sections.

Elektrodenstränge für die Elektrostahlerzeugung bestehen gewöhnlich aus Elektrodenabschnitten, die durch sogenannte Elektrodennippel miteinander verschraubt werden. Dazu wird in die Elektrodenschachtel eines Elektrodenabschnitts der doppelkonusförmige Elektrodennippel zur Hälfte eingeschraubt und der nächste Elektrodenabschnitt mit einer Krananlage über die obere Hälfte des Elektrodennippels gebracht. Zum Verschrauben des Elektrodenabschnitts muss dieser in dem Maße abgesenkt werden, wie es der Steigung des Elektrodennippel- respektive des Elektrodenschachtel-Gewindes entspricht. Entsprechende Montagehilfsmittel sind aus dem Stande der Technik bereits bekannt. Die bekannten Montagehilfsmittel weisen den Nachteil auf, dass die Gewindehülse sich über eine längere Wegstrecke, wie für die Verschraubung eines Elektrodenabschnitts mit einem Elektrodennippel notwendig ist, bewegen lässt und dass sie vor dem vollständigen Herausdrehen nur durch einen Splint gesichert ist. Es besteht deshalb die Gefahr, dass beim Verschrauben eines Elektrodenabschnitts dieser aus dem Montagehilfsmittel der Hebevorrichtung herausgeschraubt wird und durch Herabstürzen Schäden am Bedienpersonal oder an den Anlagen verursacht.Electrode strands for electrical steel production usually exist from electrode sections, through so-called electrode nipples be bolted together. This is done in the electrode box an electrode portion of the double cone electrode nipples for half screwed in and the next Electrode section with a crane over the upper half of the Electrode nipples brought. For screwing the electrode section must this in the measure be lowered, as it is the slope of the Elektrodennippel- respectively corresponds to the electrode-box thread. Appropriate assembly aids are already known from the prior art. The known assembly aids have the disadvantage that the threaded sleeve over a longer distance, as for the screw an electrode section with an electrode nipple necessary is, lets move and that they are about to completely unscrew only secured by a split pin. There is therefore the danger that when screwing an electrode section of this from the Mounting equipment of the lifting device is unscrewed and by falling down damage caused at the operating personnel or at the plants.

Die Erfindung hat sich die Aufgabe gestellt, ein Montagehilfsmittel anzugeben, welches die Nachteile des Standes der Technik vermeidet.The Invention has set itself the task of an assembly aid which avoids the disadvantages of the prior art.

Erfindungsgemäß wird die Aufgabe durch ein gattungsgemäß beschriebenes Montagehilfsmittel 1 gelöst, bei dem die Gewindehülse 4 mindestens eine solche Wegstrecke durch die Deckplatte 2 des Montagehilfsmittels 1 bewegt werden kann, wie für die Schraubverbindung eines Elektrodenabschnitts mit einem Nippel notwendig ist, wobei die Wegstrecke durch ein am oberen Ende der Gewindehülse 4 angeordnetes Sicherungselement 10 begrenzt ist, welches das Herausschrauben zuverlässig verhindert.According to the invention, the object is achieved by a generically described assembly aid 1 solved, in which the threaded sleeve 4 at least one such distance through the cover plate 2 of assembly tool 1 can be moved, as is necessary for the screw connection of an electrode portion with a nipple, wherein the distance traveled by a at the upper end of the threaded sleeve 4 arranged fuse element 10 is limited, which reliably prevents unscrewing.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 9 dargelegt.Further advantageous embodiments of the invention are in the claims 2 to 9 set forth.

Vorteilhafter Weise ist das Montagehilfsmittel 1 eines, bei dem die Gewindehülse 4 in einem Schockdämpfungselement 6 geführt ist, welches aus einer Spiralfeder 7, einem an der Deckplatte 2 befestigten Haltekäfig 8 und einer Übertragungshülse 9 besteht.Advantageously, the assembly aid 1 one in which the threaded sleeve 4 in a shock-absorbing element 6 is guided, which consists of a spiral spring 7 , one on the cover plate 2 attached holding cage 8th and a transmission sleeve 9 consists.

Weitere bevorzugte Ausführungsformen des erfindungsgemäßen Montagehilfsmittels 1 bestehen darin, dass das Sicherungselement 10, welches durch das obere Ende der Gewindehülse geführt ist, aus einem Gewindebolzen mit Kronmutter oder einer Schraube mit Splint besteht.Further preferred embodiments of the assembly aid according to the invention 1 consist in that the fuse element 10 , which is guided by the upper end of the threaded sleeve, consists of a threaded bolt with crown nut or a screw with split pin.

Weiterhin bevorzugte Ausführungsformen des erfindungsgemäßen Montagehilfsmittels 1 bestehen darin, dass das Sicherungselement 10, das auf das obere Ende der Gewindehülse 4 aufgeschraubt ist, aus einer mit einem Splint gesicherte Mutter oder einer mit einer Imbusschraube gesicherten Hutmutter oder aus zwei gegeneinander gekonterten Muttern besteht.Further preferred embodiments of the assembly aid according to the invention 1 consist in that the fuse element 10 which is on the upper end of the threaded sleeve 4 is screwed, consists of a secured with a split pin nut or a secured with a hex screw cap nut or two mutually countered nuts.

Die Erfindung wird nachfolgend an Hand einer Figur näher und beispielhaft erläutert.The The invention will be explained in more detail below with reference to a figure and by way of example.

1 zeigt einen Längsschnitt durch ein erfindungsgemäßes Montagehilfsmittel. Das Montagehilfsmittel 1 besteht aus einer Deckplatte 2 und einer bügelartig daran befestigten Hebeöse 3. Die Gewindehülse 4 mit dem Haken 5 ist in einem Schockdämpfungselement 6 geführt. Das Schockdämpfungselement 6 besteht aus einer Spiralfeder 7, die sich in einem an der Deckplatte 2 befestigten Haltekäfig 8 befin det und einer Übertragungshülse 9, in die die Gewindehülse 4 mit dem Haken 5 eingeschraubt ist. Die Gewindehülse 4 kann mindestens eine solche Wegstrecke durch die Deckplatte 2 des Montagehilfsmittels 1 bewegt werden, wie für die Schraubverbindung eines Elektrodenabschnitts mit einem Nippel notwendig ist. Am oberen Ende der Gewindehülse 4 ist ein Sicherungselement 10 angeordnet, welches das Herausschrauben der Gewindehülse 4 zuverlässig verhindert. Das Sicherungselement 10 ist eine Hutmutter, die durch eine in sie eingeschraubte Imbusschraube gegen ein Verdrehen gesichert ist. 1 shows a longitudinal section through an inventive mounting aid. The mounting tool 1 consists of a cover plate 2 and a bow-like attached lifting eye 3 , The threaded sleeve 4 with the hook 5 is in a shock-absorbing element 6 guided. The shock-absorbing element 6 consists of a spiral spring 7 , which are in one on the cover plate 2 attached holding cage 8th befin det and a transmission sleeve 9 into which the threaded sleeve 4 with the hook 5 is screwed. The threaded sleeve 4 can be at least one such distance through the cover plate 2 of assembly tool 1 be moved, as is necessary for the screw connection of an electrode section with a nipple. At the upper end of the threaded sleeve 4 is a security element 10 arranged, which is unscrewing the threaded sleeve 4 reliably prevented.
