Definitions

  • the invention relates to a device for bricking up metallurgical vessels, in particular steelwork converters, which have a closed floor, with a working platform attached to a lifting device, which can be raised and lowered into the working position and with a transport device for introducing the masonry stones onto the working platform, furthermore with a distribution device for distributing the masonry stones over the circumference of the working platform and with transfer devices for transferring individual masonry stones from the working platform into their functional position, of which a transfer device serves for the delivery of the vessel bottom with masonry stones and is also removable and removable.
  • Such devices for lining metallurgical vessels serve the economy of the metal production process and the process engineering for the production of metals, in particular steel, itself, in order to ensure the profile profile of the lining required for the production processes.
  • the device mentioned at the outset is known from DE-OS-2846544.
  • the known device offers advantages in transporting the masonry stones and although the known device is advantageous in its handling, such a solution requires a considerable amount of manual work during the start of the brickwork, that is to say when the soil is delivered. It has been shown that in particular the bottom area of the metallurgical vessel can only be advanced with difficulty, such difficulties occurring in particular when the weight of the masonry stones increases as their length increases.
  • the invention is therefore based on the object to liberate the brickwork technology even more than before from manual work, in particular in such cases when the weight of the masonry stones exceeds 32 kg and more, it being assumed that in such cases manual work anyway is considered inadmissible.
  • the transfer devices each have a horizontal swivel arm with a gripping member for a masonry stone.
  • the invention not only reduces manual labor, in particular in the bottom region of the vessel, but also enables the handling of stones over 720 mm in length, such as, for. B. of 1350 mm.
  • the invention therefore enables the infeed in the floor area for thicker bricks than before, without having to accept the disadvantages of the previous handling.
  • a particular advantage is then the simple transition in the delivery of the floor area into the wall area, in which the working platform has only a minimal overall height after removal of the lower transfer device and can therefore be lowered down to the floor lining layer in order to achieve an extremely low delivery height between the Achieve work platform and the wall areas of the vessel.
  • the device can be simplified according to a further feature in that both transfer devices can be removed and removed. If the distance between the work platform and the deepest infeed layer has become very small in higher areas of the vessel wall, it is possible to move the masonry stones in a horizontal plane with a layer-by-layer adjustment of the work platform, so that further aids are no longer required.
  • the device is further improved in that the swivel arm is rotatable and mounted on a column and that the column is attached to a holding frame supported on the edge of the work platform.
  • This solution ensures a favorable distribution of the supporting forces which result from the weight of the equipment parts themselves or from the weight of the masonry stones.
  • the column for the lower transfer device is provided with a rotatable storage platform at its lower column end.
  • the rotatable storage platform has a buffering effect, so that at least one or more masonry stones can always be saved before they are moved.
  • a rotating work platform and thus smaller masses to be moved are also saved in that the holding frame is provided so that it can be moved on the periphery of the work platform.
  • the movability with favorable supportability is characterized in that the holding frame is supported on or on rails.
  • the range of the gripping members is increased with regard to the areas to be covered by the fact that the swivel arms of the transfer device consist of articulated arms.
  • the laying of the masonry stones in the floor or wall area of the metallurgical vessel is also made easier by the fact that the gripping members on the horizontal swivel arms consist of either horizontal or vertical gripping members.
  • the device according to the invention for lining the metallurgical vessel 1 is used after the vessel bottom 1a has been closed, if a removable vessel bottom 1a should be present.
  • the device is on the hoist 2, z. B. on a crane, of which the lifting ropes 3 are visible, introduced through the mouth 4.
  • the lifting device 2 also brings the working platform 5 into the required working positions, the lifting cables 3 engaging on a crossmember 6 which is rigidly connected to the working platform 5.
  • the masonry stones 7 are fed by means of chains 8 via a transport device 9, which is not shown in detail, but only indicated, the masonry stones 7 in trough containers 10 reaching the work platform 5.
  • a distribution device 11 comprising a conveyor belt 12 and a turntable 13 is formed on the work platform 5.
  • the distribution device 11 conveys the masonry stones 7 into the area of the circumference 5a on the work platform 5.
  • the masonry stone 7 (FIG. 1) thus reaches the area of the circumference 5a via the conveyor belt 12. From there, each masonry stone 7 is moved into its respective functional position 16a in the vessel bottom 1a (FIG. 1) or 16b in the region between the vessel bottom 1a and the vessel wall 1b (FIG. 2) or 16c by means of an upper transfer device 14 and / or a lower transfer device 15 Vessel wall 1 b (Fig. 3) transported.
  • the masonry stone 7 migrates in the arrow direction 17 through the upper transfer device 14 onto the storage platform 18 and from there by means of the lower transfer device 15 into the functional position 16a, in which the masonry stones 7 are approximately vertical, as shown.
  • Such a method of operation is particularly advantageous for masonry stones 7 which have lengths of 720 mm, preferably of 1350 mm.
  • the lower transfer device 15 is disassembled and removed, so that the work platform 5 can now make full use of the space up to the finished part of the infeed in the vessel bottom 1a.
  • the masonry stones 7 fed by the transport device 9 are conveyed by the conveyor belt 12 onto the turntable 13 and from there are brought into the functional position 16b by the upper transfer device 14.
  • the transfer device 14 can also be dispensed with, if this should be desired.
  • the transfer device 14 is therefore disassembled and removed.
  • the masonry stones 7 are now brought into the functional position 16c, as will be described below.
  • the transfer devices 14 and 15 are equipped with a swivel arm 19, each of which has a gripping member 20a or 20b.
  • a gripping member can, for. B. from a known electric train (e.g. transfer device 14 in Fig. 1) or from a suction cup device (transfer device 15 in Fig. 1 or transfer device 14 in Fig. 2).
  • the swivel arm 19 is rotatable and supported on a column 21 and 22, respectively.
  • the column 21 is assigned to the upper transfer device 14 and the column 22 is assigned to the lower transfer device 15.
  • the columns 21 and 22 are fastened to a holding frame 23 which is supported on the edge 5b of the working platform.
  • the lower column 22 is fastened to the holding frame 23 and has the rotatable storage platform 18 for an advantageous temporary storage of the masonry stones 7.
  • the fasteners 22a and 22b are provided for the storage of the lower column 22.
  • the bearing platform 18 can be rotated about its longitudinal axis in the direction of the arrow 24.
  • the columns 21 and 22 pass through the movable holding frame 23 to any point on the circumference 5a. It is also possible to make the work platform 5 itself rotatable with respect to the cross member 6 by providing a rotary bearing and a drive motor, which of course means that measures for movements of the holding frame 23 become superfluous.
  • rails 25 are provided on the periphery 5b of the working platform 5 or rails 26 for guiding and supporting the holding frame, which rails are fastened to the turntable frame 13a.
  • the turntable 13 itself has its own rotary bearing on the turntable frame 13a. The necessary radii for receiving and depositing the masonry stones 7 are achieved by articulated arms 19a and 19b on the swivel arms 19.
  • the gripping members are designed for vertical masonry stones as vertical gripping members 20b (FIG. 1), such vertical gripping members 20b being fastened to traction means 27 and pivot axes 20c in order to obtain the necessary freedom of movement in the direction of arrow 17 (FIG. 1).
  • vertical gripping members 20b being fastened to traction means 27 and pivot axes 20c in order to obtain the necessary freedom of movement in the direction of arrow 17 (FIG. 1).
  • horizontal gripping members 20a are required, which are also attached to traction means 27.
  • a bridging roller table 28 is attached to the holding frame 23, so that the masonry stones 7 are pushed from the conveyor belt 12 over the turntable 13 and the bridging roller table 28 into their functional position 16c ' can.
