Beschreibungdescription
Die Erfindung betrifft eine Pfannenschlaufe als Verbindungsglied zwischen einem an einer Pfanne angeordneten Zapfen und einem Gehänge eines Kranes gemäß dem Oberbegπff des Patentanspruches 1The invention relates to a ladle loop as a connecting link between a pin arranged on a ladle and a hanger of a crane according to the Oberbegπff of claim 1
Pfannen, insbesondere Gießpfannen in einem Stahlwerk, müssen entweder zum Entleeren oder bei Erneuerung der Ausmauerung kippbar sein. Dazu wird zwischen dem Zapfen der Pfanne und dem Gehänge eines Kranes eine sogenannte Pfannenschlaufe als Verbindungsglied angeordnet Dadurch wird der Anhangepunkt soweit nach oben verschoben, daß die Pfanne unter dem Gehänge hindurch gekippt werden kann. Die rechts und links der Pfanne angeordneten Pfanneπschlaufen müssen das Gewicht der Pfanne samt Inhalt tragen. Sie bestehen aus zwei parallel im Abstand voneinander angeordneten Laschen, wobei in einem Endbereich der Laschen eine den Zapfen der Pfanne umfassende Hülse und im anderen Endbereich ein durch die Laschen sich erstreckender, im Hakenmaul des Krangehanges einlegbarer Zapfen angeordnet ist, wobei die Endbereiche von Hülse und Zapfen sich in den Lascneπ angeordneten, einander gegenüberliegenden Bohrungen abstützen und mit den Laschen lösbar verbunden sind (Lexikon der Hüttentechnik, Band 5, 1963, Seite 240, 241) Nachteilig bei der bekannten Ausführung ist, daß der Kraftfluss nur über die Laschen erfolgt, so daß die Querschnitte entsprechend ausgelegt werden müssen. Das führt zu einem Gesamtgewicht der Pfanπenschlaufen, die bei" begrenzter Maximallast für die gefüllte Pfanne der Nutzlast, d h. der Einfüllmenge verlorengeht.Pans, especially ladles in a steel mill, must either be tiltable for emptying or when the lining is renewed. For this purpose, a so-called ladle loop is arranged as a connecting link between the pivot of the pan and the hanger of a crane. As a result, the attachment point is shifted upwards so far that the pan can be tilted under the hanger. The pan loops arranged to the right and left of the pan must bear the weight of the pan and its contents. They consist of two parallel spaced tabs, with a sleeve surrounding the pin of the pan in one end area of the tabs and a pin which extends through the tabs and can be inserted into the hook jaw of the crane hanger, the end areas of the sleeve and Pins in the Lascneπ arranged, opposing bores are supported and releasably connected to the tabs (Lexikon der Hüttentechnik, Volume 5, 1963, page 240, 241). A disadvantage of the known design is that the force flow occurs only via the tabs, so that the cross sections must be designed accordingly. This leads to a total weight of the pan loops, which is lost at " limited maximum load for the filled pan of the payload, ie the filling quantity.
Aufgabe der Erfindung ist es, eine Pfannenschlaufe anzugeben, die bei gleicher maximaler Traglast signifikant weniger Gewicht hat als herkömmliche Pfannenschlaufen Die gestellte Aufgabe wird ausgehend vom Oberbegriff in Verbindung mit den kennzeichnenden Merkmalen des Patentanspruches 1 gelost Vorteilhafte Weiterbildungen sind Bestandteil von UnteraπspruchenThe object of the invention is to provide a ladle loop that has significantly less weight than conventional ladle loops with the same maximum load The task is solved starting from the preamble in conjunction with the characterizing features of claim 1. Advantageous further developments are part of sub-claims
Nach der Lehre des Patentes sind die Hülse der Zapfen und die Laschen aus einerAccording to the teaching of the patent, the sleeve of the pin and the tabs are made of one
Werkstoffgute hergestellt und form- und gewichtsoptimiert miteinander verbunden und bilden ein isotensisches geschlossenes Kettenglied Wesentlicher Ansatz der neugestalteten Pfannenschlaufe ist die Einbeziehung von Hülse und Zapfen zur Traglastubertragung, so daß überflüssiges Laschenmaterial eingespart werden kann Bei der bekannten Konstruktion war die Querschπittsauslegung im Bereich desGood materials are manufactured and connected to each other in an optimized form and weight and form an isotensic closed chain link. An essential approach of the redesigned ladle loop is the inclusion of sleeve and pin for load-bearing transmission, so that unnecessary tab material can be saved
Zapfens für die Traglastubertragung gerade ausreichend im Bereich der Hülse aber überdimensioniert Die vorgeschlagene Pfannenschlaufe ist dagegen so ausgelegt, daß alle Querschnittsbereiche gleichmaßig beansprucht werden Eine so gestaltete Pfanπenschlaufe kann emstuckig sein, sei es als Stahlgußstuck, sei es als ein aus dem Vollen hergestelltes Schmiedestuck Von den Herstellkosteπ her und im Hinblick auf eine Anpassung an verschiedene Krangehange und Pfannenzapfen wird der geschweißten Ausfuhrung der Vorzug gegeben Wesentlich dabei ist, daß die Schweißnahte mit tragen und nicht nur zur Fixierung von Hülse und Zapfen in den Laschen dienenPin for the load transfer just enough in the area of the sleeve but oversized The proposed ladle loop, on the other hand, is designed so that all cross-sectional areas are equally stressed Manufacture cost ago and with a view to adapting to various crane hangers and ladle pins, the welded version is given preference. It is essential that the weld seams are used and not only used to fix the sleeve and pin in the tabs
Um keine Kerbspannungen im Schweißnahtbereich zu erzeugen, sind in dem an der Schweißnaht unmittelbar angrenzenden Bereich abgerundete Ausnehmungen im Sinne von Entlastungsπuten angeordnet Mit dieser Art der Ausbildung der Pfannenschlaufe kann das Gewicht für beide Pfannenschlaufen um bis zu mehr als 2 t reduziert werden, was der Nutzlast zugute kommt Dabei bilden die Elemente der Pfanπenschlaufe zusammen mit dem Krangehange ein Tragsystem spanπuπgsgleicher Querschnitte Bei Werkstoffgleichheit von Pfannenschlaufe und Krangehange giltIn order not to generate notch stresses in the weld seam area, rounded recesses are arranged in the area immediately adjacent to the weld seam in the sense of relief grooves. With this type of pan loop, the weight for both pan loops can be reduced by up to more than 2 t, which increases the payload The elements of the ladle loop together with the crane hangers form a support system with the same cross-sections if the material of the ladle loop and crane hangers is the same
F n + F 1 2 = F 2 ι + F 22 = F 3 = F 4 (1)F n + F 1 2 = F 2 ι + F 2 2 = F 3 = F 4 (1)
wobei F T -, + F T 2 die Querschnittsflachen der Hülse und F 2 , + F 22 die Querschnittsfiachen der Laschen und F 3 die Querschnittsflache des Zapfens der Pfannenschlaufe und F _ die Querschnittsflache des Krangehanges ist Bei dieser Betrachtungsweise werden die Schweißnahte in die Berechnung nach der Finite- Elemente-Methode (FEM) mit einbezogen und als Gitterstruktur modelliertwhere FT -, + F T 2 is the cross-sectional area of the sleeve and F 2 , + F 22 is the cross-sectional area of the tabs and F 3 is the cross-sectional area of the pin of the socket loop and F _ is the cross-sectional area of the crane hanger The weld seams are considered in the calculation according to the finite element method (FEM) and modeled as a lattice structure

Dabei liegt die Achse 14 desThe socket loop 1 consists of two parallel, spaced-apart tabs 2, 3. In the lower end area of the tabs 2, 3, a sleeve 4 is arranged, which according to the invention is connected to the two tabs 2, 3 via load-bearing weld seams 5, 6. The sleeve 4 has in this exemplary embodiment a larger diameter 7 compared to the width 8 of the tabs 2, 3. This is advantageous for the outlet of the weld seam 5. In a known manner, the bore of the sleeve 4 is designed as an elongated hole, which is due to the offset of the two axes 9, 10 can be seen This execution of the sleeve 4 is chosen so that when the pan is in the pan the loop 1 can settle down and at the same time is locked in the upper area. In the upper end area of the two tabs 2, 3 the pin 11 is arranged, which also according to the invention load-bearing welds 12, 13 is connected to the two tabs 2, 3. The axis 14 of the
