Definitions

  • a lifting device and a treatment device of the type mentioned are from the WO 2015/003 925 A1 known.
  • the known lifting device is already working quite well. Due to the construction of the lifting device, however, accessibility to a treatment device arranged in the upper region of the lifting device or above the lifting device is restricted.
  • the object of the present invention is to provide means by which the problems of the prior art can be avoided.
  • a lifting device of the type mentioned is configured in that the crossbars are arranged above the crossbars, that the hydraulic cylinder units act such that the crossbars are moved when extending the piston up and retracting the piston down and that the hydraulic cylinder units as a servo cylinder are formed.
  • the hydraulic cylinder units continue to have an integrated path measuring system.
  • a positionally accurate method of the cross beams is possible in a simple manner.
  • the crossbars are guided on both sides by vertically extending guide elements.
  • the crossbars are guided on both sides by vertically extending guide elements.
  • the hooks are connected to their respective crossbar via a vertically extending connecting element, wherein a length of the connecting elements is dimensioned such that the hooks are arranged with retracted piston below the cross struts.
  • a vertically extending connecting element wherein a length of the connecting elements is dimensioned such that the hooks are arranged with retracted piston below the cross struts.
  • the object is further achieved by a treatment device having the features of claim 5.
  • An advantageous embodiment of the treatment device is the subject of the dependent claim. 6
  • the lifting device of the treatment device is designed as a lifting device according to the invention, and furthermore the treatment device is arranged above the transverse struts of the lifting device.
  • the treatment device has a treatment vessel and a manifold arranged above the treatment vessel.
  • the accessibility to the treatment device can be optimized by arranging the transverse bars below the treatment vessel when the piston of the hydraulic cylinder units is retracted.
  • FIG. 1 should be raised by means of a lifting device 1, a metallurgical pan 2 as needed and lowered again.
  • liquid metal for example molten steel
  • the lifting device 1 has two pairs 4 of vertically aligned posts 5.
  • the total of four posts 5 usually define a rectangle.
  • each one of the two pairs 4 is according to FIG. 2 each mounted a horizontally oriented cross member 6.
  • FIG. 2 shows either the in FIG. 1 left pair 4 from the direction of arrows A or the in FIG. 1 right pair 4 from the direction of the arrows B.
  • the Per crossbar 6 is ever a crossbar 7 available.
  • the crossbars 7 are arranged above the transverse struts 6.
  • the respective Transverse bar 7 can be positioned by means of a respective single hydraulic cylinder unit 8 relative to the respective transverse strut 6 in the vertical direction.
  • the hydraulic cylinder units 8 are arranged between the transverse struts 6 and the transverse beams 7 as viewed in the vertical direction.
  • the respective piston 10 can be moved in and out relative to the respective hydraulic cylinder 9.
  • the hydraulic cylinder units 8 act in such a way that the transverse bars 7 are moved upward when the pistons 10 are extended and when the pistons 10 retract.
  • Each a hook 11 is arranged.
  • the hooks 11 serve to receive a respective pin 12, which in turn is arranged on the metallurgical pan 2.
  • the hooks are arranged hanging on the crossbar 7.
  • the hydraulic cylinder units 8 are designed as servo cylinders.
  • Servo cylinders are as shown in FIG. 7 integral structural units which internally in addition to the respective hydraulic cylinder 9 and the respective piston 10 and a hydraulic pump 13 and a small hydraulic reservoir 14 and - for example in a valve unit 15 - have the required hydraulic valves 16.
  • the hydraulic cylinder units 8 may further comprise an integrated displacement measuring system 20.
  • the crossbars 7 can each be guided on both sides by vertically extending guide elements 21 become.
  • the guide elements 21 may be part of the post 5 or be connected to the post 5. Alternatively, they can be self-contained elements.
  • the hooks 11 are preferably connected to their respective transverse bar 7 via a respective connecting element 22.
  • the respective connecting element 22 extends in the vertical direction.
  • a length l of the connecting elements 22 is preferably dimensioned such that the hooks 11 are arranged below the transverse struts 6 when the piston 10 is retracted, ie in the lowest position of the transverse bars 7 and thus also the hook 11.
  • the lifting device 1 is as shown in FIG. 8 often part of a treatment device for the liquid metal 3, which is located in the metallurgical pan 2.
  • the treatment device furthermore has a treatment device 23 for treating the liquid metal 3.
  • the treatment device 23 generally has a treatment vessel 24 and a manifold 25 arranged above the treatment vessel 24.
  • the treatment device 23 is preferably arranged above the transverse struts 6 of the lifting device 1. Furthermore, - at least in the rule - with retracted piston 10 of the hydraulic cylinder units 8, ie in the lowest position of the crossbar 7 and thus also the hook 11, the crossbars 7 are arranged below the treatment vessel 24.
  • the present invention has many advantages:
  • the lifting device 1 can be installed to save space.
  • the accessibility to the treatment device 23 and also to the hydraulic cylinder units 8 is improved.
  • the number of hydraulic cylinder units 8 is minimized.
  • a hydraulic piping and a hydraulic power pack can be saved.
