Definitions
- the 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 Oberbeg ⁇ ff of claim 1
- Pans especially ladles in a steel mill, must either be tiltable for emptying or when the lining is renewed.
- a so-called ladle loop is arranged as a connecting link between the pivot of the pan and the hanger of a crane.
- 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.
- the 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.
- the sleeve of the pin and the tabs are made of one
- the proposed ladle loop 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
- pan loop designed according to the invention is explained in more detail using two exemplary embodiments. It shows
- Figure 1 is a front view of a designed according to the invention
- Figure 2 shows a section in the direction A-A in Figure 1
- FIG. 4 shows a section in the direction A-A in FIG. 3
- FIG. 5 shows a schematic diagram of the supporting system according to the invention of cross sections of equal voltage
- the socket loop 1 consists of two parallel, spaced-apart 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.
- 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.
- the pin 11 is arranged, which also according to the invention load-bearing welds 12, 13 is connected to the two tabs 2, 3.
- FIGS. 3 and 4 show a second exemplary embodiment, the same reference numerals being used for the same parts.
- the elements of the pan loop 20 are designed in a different way.
- the tabs 21, 22 comprise the
- Pin 1 1 only to a certain extent, namely approximately 180 degrees.
- the sleeve 23 has no elongated hole and the diameter 7 corresponds approximately to the width 8 of the tabs 21, 22 or is even smaller.
- This pan loop 20 is also weight-optimized, since it is also one Support system of tension-equal cross-sections corresponds
- Figure 5 shows a P ⁇ zipdargna the support system according to the invention equal cross-sections with the same material, the cross sections F, 1 + F 1 2 of the sleeve 23 correspond to the cross section F 2 l + F 22 of the tabs 21, 22 and the cross section F with the same material of the crane hanger 19 3 of the pin 11 and this in turn the cross-section F of the crane hanger 19
- the cross-sectional view of the load-bearing weld seam, not shown here, is not taken into account
