Definitions

  • the invention relates to a converter with a removable bottom, which is fastened by means of a number of rocker-shaped tension levers arranged around its circumference to the converter jacket or to a supporting structure connected to it, the tension levers coming from or into the engagement. position can be moved with the floor.
  • the invention relates to an improvement or further training of the above-mentioned construction.
  • the object is to carry out a longitudinal displacement of the tensioning lever with little effort by using the tensioning means both for tensioning and for releasing the tensioning lever from the holding position.
  • clamping means articulated with the tensioning lever can be tensioned against an abutment, the abutment having a guide element engaging in an arcuate guideway, and after loosening the tensioning means the same can be pivoted along the guideway from the vertical tensioning position into a release position is.
  • a tensioning means designed as a tensioning screw
  • a nut that can be screwed along the tensioning screw can be tensioned against the abutment, the guideway being designed as a backdrop into which the guide element, which is designed as a guide bolt and which is fastened to the abutment, engages.
  • the guideway expediently has a stop to limit the pivoting movements of the clamping screw.
  • the longitudinal movement of the clamping screw is also advantageously limited by a stop.
  • FIG. 1 shows the fastening device for the converter base in the clamping position
  • Fig. 2 shows a section along the line 11-11 in Fig. 1
  • Figs. 3 and 4 show successive positions of the clamping screw and the clamping lever in the release position.
  • the converter base denoted by 1 is fastened with clamping levers 2 and clamping screws 3 to a support structure 5 fastened to the converter casing 4.
  • the clamping screw 3 is pivotally connected to the clamping lever 2 by a hinge pin 6 and guided with its threaded shaft by an abutment 7 with play.
  • the clamping screw can be tightened with the nut 8 relative to the abutment 7.
  • guide pins 9, 9 ' are provided on both sides, which are slidable in the slot or link guides 10, 10' attached to the support structure 5.
  • the clamping nut 8 is tightened against the abutment 7, the clamping screw 3 being in the vertical position and the front end of the clamping lever 2 resting against the converter base 1.
  • the nut 8 is loosened, the tensioning lever 2 loosening.
  • the clamping screw 3 can be pivoted into the position shown in FIG. 3, the bolts 9; 9 'are guided in the slot guides 10, 10'.
  • the converter base 1 is inserted and fastened in the reverse order.
  • the slot guide is expediently provided with stops 13, 13 'to limit the pivoting movement.
  • the clamping screw can also have stops 14, 14 'to limit their longitudinal movement.
  • the converter base fastening device shown can be modified in various ways; it would be e.g. It is possible to design the hinge pin 6 as a guide pin instead of the guide pins 9, 9 'and to guide it in a guide track provided on the support structure 5.
