Definitions

  • the invention relates to a turret for ladles with two mutually opposed, substantially symmetrical to the axis of rotation, at their free ends each provided with a receiving device for a ladle, fork-shaped in plan view, which is pivotally mounted on a part of the tower rotatable about the axis of the turret and can be pivoted to a limited extent in the vertical plane with the aid of at least one lifting means articulated at one end on the turret and at the other end on the lever, in particular a pressure medium-actuated cylinder-piston arrangement, each lever being provided with two arms firmly connected by means of a cross member and a deformable with corresponding links Articulated crank gear forms.
  • a revolving tower of this type in which a cantilever which is rotatable approximately in the horizontal direction and essentially symmetrical to the pivot point and which receives the ladles at both ends, is e.g. known from DE-AS-2044979.
  • the boom is pivotally supported in a vertical plane limited from its horizontal position on a pedestal. Alternating loadable lifting elements are provided on both sides of the swivel joint.
  • the height of the two ladles depends on the movement.
  • this dependency has proven to be a disadvantage.
  • the second pan must be adjustable in height independently of the position of the first pan.
  • the invention has for its object to provide a turret of the type mentioned, which does not have the disadvantages recorded, but rather is designed so that maintenance is particularly easy with the simple structure - or assembly work can be simplified.
  • levers are not - as before - pivoted about an axis included in the lever, but in bearings that are open in plan view, the lever, e.g. with the help of a crane, simply lifted off during dismantling or placed in the bearings during assembly. This considerably simplifies assembly, which is particularly advantageous for maintenance, inspection and repairs.
  • the free space in the middle of the turret can be used to build work platforms from which the pans are more accessible. This is important for observation, temperature measurements, adding supplements, etc.
  • a telescopic plunger cylinder can optionally be used to further simplify the hydraulic lines.
  • a fixed foundation frame 2 is attached to a base 1.
  • a rotationally driven support ring 3 is rotatably supported.
  • the axis of rotation of the support ring is also the axis of rotation of the entire turret.
  • a ring 4 is provided, which is in engagement with the gears 5 of a fixedly arranged rotary drive 6 (FIG. 2).
  • the support ring 3 is designed to be relatively low.
  • the sides of the ring and its upper base are stiffened because they have to withstand high loads.
  • the turret is equipped with two levers 7 arranged opposite to each other and essentially symmetrical to the axis of rotation, which operate independently of one another.
  • the levers are fork-shaped.
  • Each lever consists of two load arms 8 which extend substantially perpendicular to the axis of rotation of the turret and which are firmly connected to one another by a torsionally rigid cross member 9.
  • the load arms form a U-shape (fork shape) with the cross member in plan view.
  • a power arm 10 is welded to the cross member 9.
  • the force arms 10 are offset from one another in the horizontal plane for construction reasons.
  • the force arms 10 are angled substantially vertically downward in a Z-shape, so that the lower end part of the force arm 10 - viewed in the view - runs approximately parallel to the load arms.
  • transducers 11 - essentially of conventional construction - are arranged for ladles 12.
  • the hook 13 of a crane, not shown, is drawn, with the help of which the ladle etc. is inserted into or removed from the transducer.
  • the two levers 7 are pivotally mounted on the top of the upper base of the support ring 3.
  • the swiveling movement, which takes place in the vertical plane, is naturally limited accordingly.
  • open bearings 14, 14 ' are provided on the base 3a in plan view.
  • the bearing 14 is a spherical axial spherical plain bearing, while the bearing 14 'is a spherical rolling bearing.
  • the different versions of the bearings are only shown as an example, naturally bearings of one type are always used in a rotating tower. To protect against unwanted shock loads, this storage is provided with the usual lifting safeguards (not shown).
  • each lever 7 The pivoting movements of each lever 7 are provided by a lifting means, in the example shown a pressure-actuated cylinder-piston arrangement 15, which is arranged in the region of the axis of rotation of the turret, as within the support ring 3, essentially in the vertical direction.
  • the pressure cylinders 16 are articulated on the underside 3a of a crossbar 25, which is fastened to the support ring 3 with the aid of screws, at (18), while the piston (or plunger) 17 is articulated to the power arm 10 at (19).
  • the load arm is relatively long. This gives a large stroke with a small side shift.
  • the force arm 10 is advantageously articulated to the piston 17 of the cylinder-piston arrangement 15. This eliminates the need for a special end position safety device because the cylinder is positively connected to the lever in the end position. It is also possible for several cylinders to engage the power arm. However, the same torsional strength of the crossbar must be maintained so that the load can be held in the event of a cylinder failure.
  • Electro-mechanical drives can also be used as lifting devices, e.g. one or more lifting spindle elements that are subjected to tensile or compressive loads during the load stroke.
  • weighing devices can naturally also be provided, which can advantageously be arranged under the lever bearing.
