Definitions

  • the invention relates to a support tower for metallurgical vessels of different dimensions, in particular for casting ladles of different sizes in a continuous casting installation, with at least one support arm projecting from a support column which has two support arms which laterally encompass the metallurgical vessel and on which movable supports are provided for support devices provided on the metallurgical vessels are.
  • metallurgical vessels in particular ladles, of different dimensions or different structural designs are generally used for the same purpose.
  • the metallurgical vessels (ladles) serving as storage containers are carried by a support tower with a cantilevered support arm.
  • the support arm has two support arms which laterally encompass the metallurgical vessel, on each of which a support is provided for a support device provided on the metallurgical vessel, such as a support tab of a ladle.
  • a support tower one is bound to the use of metallurgical vessels of a very specific size and design, which is determined by the distance between the two supports provided on the support arms, their cross-sectional shape and their height.
  • This is disadvantageous for a continuously running casting operation, in particular a continuous casting operation.
  • Another disadvantage is that it does not make it possible to optimally use and utilize the mobile cranes of various sizes and load capacities that are generally used for vessel transport in hut operations.
  • the invention therefore has as its object to provide a support tower of the type described in the introduction, which enables the use of any number of different metallurgical vessels on one and the same arm of the support tower.
  • each support arm is provided with at least two different, mutually interchangeable supports, which are each arranged on a common support body that is movable relative to the support arm.
  • the support bodies are rotatably mounted about a vertical axis provided on the respective support arm.
  • the supports of each support arm are expedient at different heights on the supporting body arranged.
  • the supports of each support arm have different cross-sectional shapes from one another, which can be brought into engagement with correspondingly differently shaped support devices of the metallurgical vessels.
  • each support arm on the support body are expediently arranged at different distances from the axis of rotation of the support body.
  • the drive for the rotatable support body can be designed in various ways, but it has proven to be particularly advantageous if a motor is mounted on the support arm and is connected to the support body for synchronous rotation thereof via drive shafts.
  • FIGS. 1, 3 and 5 being a partially sectioned side view of a support tower in accordance with one embodiment
  • FIGS. 2, 4 and 6 each an associated plan view of the one in FIGS. 1, 3 and 5 show the support towers shown.
  • the support tower has two cranked support arms 2, 3 which can be pivoted independently of one another about a column 1.
  • Each of the support arms 2, 3 has two support arms 4, 5 which laterally encompass the metallurgical vessel (not shown here) and on the front ends 6 of which a support body 8 which is rotatable about a vertical axis 7 is mounted.
  • Each of these support bodies 8 has a pin 11 which is mounted in the support arm 4, 5 by means of an axial radial bearing 9 and a radial bearing 10 and which is provided at its lower end with a gear wheel 12 rigidly attached to it.
  • each support body 8 is approximately triangular.
  • a pan receptacle 13, 14, 15 is provided on each of the three sides of the support body, the pan receptacle of each support body differing from one another in three ways:
  • the pan receptacles 13, 14, 15 have different cross-sectional shapes, they are arranged at different distances 16, 17, 18 from the axis 7 of the supporting body 8 (FIG. 2) and they are furthermore at different heights 19, 20, 21, as shown in FIG. 1 can be seen, arranged on the support body 8.
  • a shock-absorbing element 25 is installed between the socket receptacles 13, 14, 15 and the brackets 22, 23, 24 provided on the support body 8 and integrally formed with it.
  • a motor 26 is mounted on each support arm 2, 3, which is connected to both support bodies 8 of the support arm 2, 3 by means of schematically illustrated drive shafts 27 and corner gears 28, the last drive shaft being connected to a Gear engages in the gear 12 mounted at the lower end of the pin 11.
  • the support body 8 are mutually identical, so that they, in each case two corresponding socket receptacles 13, 14, 15 inwards, i. H. to pivot between the support arms 4, 5, can be rotated synchronously.
  • the two support arms 29, 30 and 31, 32 are not pivotable independently of one another, but can only be pivoted together due to their integral design.
  • the embodiment according to FIGS. 3 and 4 also has its own motor 26 for each support arm.
  • a single motor 33 is provided for rotating all the supporting bodies 8 of the two supporting arms 31, 32, wherein only one pair of supporting bodies of one supporting arm 31 or 32 can be rotated by means of clutch couplings 34, 34 '. By switching on one of the clutches 34 or 34 ', the other is automatically switched off.
  • the support tower according to FIGS. 5 and 6 is inserted with its column 35 into a guide column 36 surrounding it and can be raised and lowered by means of a lifting cylinder 37.
  • the drive for pivoting the support arms is designated 38.
  • Fig. are shown with dashed lines different sized pans 39, 40, 41, as they can be used in this support tower.
  • the distances 42, 43, 44 from the center lines 45, 46, 47 of the support devices 48, 49, 50 of these different pans 39, 40, 41 to their center line 51 are different in each case. 5 that the bottoms 52, 53, 54 of these different pans 39, 40, 41 are at the same height 55, so that the distance 56 between that below the respective ladle 39 or 40 or 41 located intermediate vessel 57 and the bottom 52 or 53 or 54 of the ladle (with support arms 31, 32 located at the same height) is always the same size.
  • the invention is not restricted to the exemplary embodiments shown, but can be modified in various ways. So it is possible to provide only two or more than three socket receptacles on each support body.
  • the rotary drive for the support body can also be done by hand. However, it can also be carried out electrically-mechanically, hydraulically-mechanically or pneumatically-mechanically.
