Definitions

  • the invention relates to a ladle loop as a connecting link between one a pan arranged pegs and a hanger of a crane according to the Preamble of claim 1.
  • Pans especially ladles in a steel mill, have to either Empty or be tiltable when the lining is renewed. To do this, between a so-called the tenon of the pan and the hanger of a crane Pan loop arranged as a connecting link. This becomes the attachment point moved upwards so far that the pan tipped under the hanger can be.
  • the pan loops arranged to the right and left of the pan must support the weight of the pan and its contents.
  • the object of the invention is to provide a ladle loop that is the same maximum load has significantly less weight than conventional ones Pan loops.
  • the sleeve, the pin and the tabs are made of one Material quality manufactured and connected to each other in a form and weight optimized form an isotensic closed chain link.
  • Essential approach of redesigned pan loop is the inclusion of sleeve and spigot Load transfer, so that unnecessary tab material can be saved.
  • the cross-sectional design was in the range of Pin just sufficient for the load transfer, but in the area of the sleeve oversized.
  • the proposed ladle loop is designed that all cross-sectional areas are equally stressed.
  • One designed like this Pan loop can be in one piece, be it as a steel casting or be it as one forgings made in full. In terms of manufacturing costs and in terms of to adapt to different crane hangings and ladle pins welded version is preferred. It is essential that the Carry weld seams with and not only to fix the sleeve and pin in the Serve tabs.
  • pan loop design In order not to generate notch stresses in the weld seam area, rounded recesses in the sense of relief grooves are arranged in the area immediately adjacent to the weld seam. With this type of pan loop design, the weight for both pan loops can be reduced by up to more than 2 t, which benefits the payload.
  • the elements of the ladle loop together with the crane suspension form a load-bearing system of cross-sections of equal tension.
  • FEM finite element method
  • the pan loop 1 consists of two parallel ones at a distance from one another arranged tabs 2, 3.
  • a sleeve 4th arranged, according to the invention via load-bearing welds 5, 6 with the two Tabs 2, 3 is connected.
  • the sleeve 4 has in this embodiment larger diameter 7 compared to the width 8 of the tabs 2, 3. That is from Advantage for the outlet of the weld seam 5.
  • the bore is Sleeve 4 formed as an elongated hole, which is due to the offset of the two axes 9, 10th becomes recognizable. This version of the sleeve 4 is chosen so that when turned off Pan the pan loop 1 can settle down and at the same time in the upper area is locked.
  • the invention also via load-bearing welds 12, 13 is connected to the two tabs 2, 3, the axis 14 of the Pin 11 above the center 15 of the radius of curvature 16 of the upper End area of the two tabs 2, 3.
  • This offset material of the Tabs 2, 3 saved above the pin 11, which optimizes weight Benefit To relieve the weld area, both the pin 11 and also provide the sleeve 4 with grooves 17, 17 ', 18, 18'.
  • FIGS. 3 and 4 A second exemplary embodiment is shown in FIGS. 3 and 4, wherein for the same parts the same reference numerals have been used.
  • the tabs 21, 22 include the Pin 11 only over a certain extent and approximately 180 degrees.
  • the Sleeve 23 has no elongated hole and the diameter 7 corresponds approximately to the width 8 the tabs 21, 22 or is even smaller.
  • This pan loop 20 is also weight-optimized, since they are also tension-equal to a support system Cross sections.
  • FIG. 5 shows a basic illustration of the support system according to the invention of cross sections of equal voltage. If the material of the crane hangers 19 and the ladle loop 20 is the same, the cross sections F 1.1 + F 1.2 of the sleeve 23, the cross section F 2.1 + F 2.2 of the tabs 21, 22 and this correspond to the cross section F 3 of the pin 11 and this in turn corresponds to the cross section F 4 of the Crane hanger 19. The cross-sectional view of the load-bearing weld seams not shown here is not taken into account.
