Definitions

  • the invention relates to a drive device for a stopper closure on a metallurgical vessel according to the preamble of claim 1.
  • the motor is detachably arranged on the underside of the drive shaft and on the upper side this drive shaft protrudes from a cylindrical housing of the guide arrangement, and a support arm for holding the plug can be fastened to this.
  • the invention is based on the object of further developing a drive device for a stopper closure in such a way that it achieves increased stability or rigidity and thus more precise metering during casting.
  • the user-friendliness of the drive device is to be improved with regard to its assembly and when manipulating the plug.
  • this object is achieved in that this adjusting means for the plug is mounted so as to be vertically displaceable on at least one bearing shaft fixed in the housing.
  • the adjustment means comprises at least one upper and one spaced-apart lower bearing, each guided on the bearing shaft, as well as a sleeve element connecting the latter.
  • Fig. 1 shows a drive device 10 for a stopper closure on a metallurgical vessel, which is explained in more detail below.
  • This drive device 10 comprises a housing 12 that can be mounted on the vessel, an adjusting means 15 mounted in this so as to be vertically displaceable, with a drive 14 that can be coupled to this, and an upper connection element 13 for a support arm holding the refractory or metallic stopper. Both the axis A of the adjustment direction of the drive device 10 and the plug are normally oriented vertically.
  • the adjustment means 15 is mounted on at least one bearing shaft 11 fastened in the housing 12 so as to be vertically displaceable. This makes it possible for this vertically displaceable adjusting means 15 to be located inside the housing 12 in every operating position and thus for the stopper held via the support arm to be held extremely rigidly.
  • the upper bearing 16 is surrounded by the sleeve element 18 and the latter by a head piece 19 of the adjusting means 15, which moves inside the tubular housing 12.
  • the housing 12 is provided in the upper area with a sealable lateral opening 12 'through which the connecting element 13 connected to the head piece 19 protrudes, which is located outside the housing.
  • the opening 12 ' is also closed by a foldable seal 21 so that the interior of the housing 12 with the Storage 16, 17 is protected from dirt particles such as dust.
  • These bearings 16, 17 are additionally protected with dirt wipers, not shown in detail.
  • the bearing shaft 11 is fastened at its ends in the tubular housing 12 by a cover 22, 23 and it extends in a coaxial alignment with this housing 12 to its upper or lower end. It and with it the upper bearing 16 and the support arm attached to the connection element 13 are mounted pivotably about the shaft axis A. This means that the stopper can be precisely centered on the outlet sleeve that corresponds to it before it is put into operation.
  • the connection element 13 for the support arm is arranged at least approximately at the upper bearing 16 to increase stability.
  • a disk 27 rotatable in the cover 22 is rotatably connected to the bearing shaft 11 and is shaped on the outer circumference as an orbital path 27 ′ that interacts with a rotatable lever 26. With this lever 26 on the top of the housing 12 there is optimal access for the operating personnel.
  • the sleeve element 18 is radially spaced from the bearing shaft 11 between the upper and lower bearings 16, 17 and forms therein an annular chamber 31 in which a spring element 24 and a spacer ring 29 are contained one above the other.
  • a compression spring is preferably used for this spring element 24, which is compressed by the upper bearing 16 when the adjusting means 15 is moved downwards and thus enables weight compensation through which the stopper can be moved upwards with less effort in the operating state.
  • a drive 14 is provided at the lower end of the housing 12 for raising and lowering the adjusting means 15, in particular for an automated but also for a manual operation of the stopper closure during pouring.
  • This drive 14 can be coupled to a coupling element 32 with an actuatable locking lever 32 'on an associated mounting plate 30 and is therefore easily accessible to the operating personnel during casting.
  • This drive 14 advantageously functions electromechanically as a linear drive, but could also be designed as a hydraulic piston / cylinder unit.
  • connecting elements 18 ′ which protrude through the lower cover 23 of the housing 12 and have a coupling element 33 located below the housing 12 for a detachable connection to a lifting rod of the drive 14.
  • an indicated lever linkage 20 for manual operation is on this coupling element 33 Raising and lowering the adjusting means 15 and thus the plug is articulated.
  • a base plate 35 which can be fixed on the vessel.
  • two mutually spaced upwardly projecting sliding blocks 37 are arranged on the base plate 35, between these the mounting plate 30 is positioned with its lateral centering surfaces 34 and it can be supported at the bearing surfaces 36, so that the drive device 10 with the housing 12 on the Vessel can be mounted or removed from it.
  • lateral recesses 38 are arranged in the mounting plate 30 and bolts 38 'protruding through them on the base plate 35 on the vessel, by means of which additional positioning of the mounting on the base plate takes place.
  • Fig. 3 shows the drive device 10 on a partially shown vessel 40, which is used as a so-called distributor in a continuous casting plant and in which the poured melt is passed in a known manner through a refractory or partially metallic immersion tube 41 of a changing device 42 into a mold, not shown in detail.
  • the vessel can also be a pan or any container or furnace containing molten metal.
  • This distributor is not discussed in more detail below, since, as mentioned, it is known per se.
  • FIG. 2 There are opposite Fig. 2 In addition, the support arm 43 fastened to the connection element 13 of the drive device 10 and the refractory plug 44 held at the front by fastening means 46 are shown.
  • this lever linkage 20 for the manual raising and lowering of the adjusting means 15 and thus the plug 44 is illustrated. It consists of reversing levers 47 which are articulated to the coupling element 33 of the adjusting means 15 and which are rotatably connected to a longer hand lever 45 which can be removed when the drive 14 is automatically controlled for pouring. These deflection levers 47 are also operatively connected to a parking brake 48 in order to hold the adjusting means (15) in any position. With this hand lever 45 on the underside of the vessel 40 there is the advantage that the operator has eye contact with the mold. Furthermore, a removable cover 52 is arranged below the housing 12.
  • a fixed or removable adjusting device 50 with a holder 51 and at least one hand lever 49 is provided on the top of the housing 12, which can be connected to the connection element 13 or the support arm 43 of the adjusting means 15 and by means of the one on the top or on the side of the vessel 40 standing operator can raise and lower the support arm 43 and thus the plug 44 along the vertical axis A.
  • a fixed or removable holding element for example a tab, can also be used, preferably on the top side of the housing 12, for transporting the drive device 10. This does not result in any Forces or bending moments on the bearings or on the adjustment means when transporting the same.
  • bearing shaft could be arranged next to one another and correspondingly designed bearings could be provided.
  • the bearing shaft could also be provided with a cross section other than round, for example square, rectangular, polygonal, polygonal or the like.
  • the sleeve element could be designed as a cage, struts and / or the like or the connection element in two or more parts or differently than shown.
