Definitions

  • the invention relates to a device for handling slabs, in particular produced by continuous casting, the surfaces of which are ground before rolling in a rolling mill, wherein the slab on a reversing grinding table is moved back and forth under an arranged in a grinding booth grinding unit of a grinding unit, the Grinding table after grinding a surface linearly moved out of the grinding booth, the slab lifted from the grinding table and a turning device is supplied, the slab is removed after turning from the turning device and spent with the unprocessed, other surface overhead on the grinding table, the then re-enters the grinding booth to machine this surface.
  • the invention is therefore an object of the invention to provide a device for handling when grinding continuously cast slabs with a simultaneously greatly reduced structural complexity.
  • the slab can be picked up by a slab manipulator having a rotatable slab clamping and lifting means with which the clamped slab can be transversely transported as well as turned over. It can thus unify all the relevant functions for transporting, lifting, lowering, clamping and turning of slabs in an aggregate, namely the multifunctional slab manipulator, which is programmed from a central point or controlled.
  • a preferred embodiment of the method provides that the slab positioned on the grinding table, temporarily stored on a stationary tray or fed by a roller table, can be run over by the slab manipulator, which is moved up from a starting position engaging the laterally spaced parallel position to the slab and the slab with an open slab clamping and lifting means, whereupon the slab clamping and -hebesch closed and the slab manipulator is moved with the clamped slab in a turning position in which the slab turned by turning the slab clamping and lifting means and then driven the slab manipulator on the grinding table, there the slab clamping and lifting means to the circulation of Slab is lowered on the grinding table and then opened and the slab manipulator is moved to the laying of the slab in its starting position with lateral parallel position to another slab.
  • the slab manipulator which is moved up from a starting position engaging the laterally spaced parallel position to the slab and the slab with an open slab clamping and lifting means, whereupon the slab clamping and -hebesch closed and the slab manipulator is moved with the clamped slab in a turning
  • the slab manipulator can be moved transversely between at least one existing grinding table, one or more stationary slab trays and the turning position and optionally a roller table for receiving a slab to be ground or for transporting the finished ground slabs.
  • the multifunctional slab manipulator whose substructure for the carriageway or rails of the transverse transport can be made of concrete, thus fulfills all logistical tasks.
  • two spaced adjacent grinders can be under caching on stationary shelves a steady grinding operation and ensure the continuous occupancy of the just not grinding grinding unit with a slab to be processed.
  • the slab In the initial position of the transport and turning cycle, the slab is thus either on a grinding table or on a stationary slab rest.
  • the slab manipulator finds enough clearance to turn the slab by 180 ° for grinding the broadside surfaces.
  • a device provides that in the outlet region of at least one grinding machine unit, in which the grinding table is moved linearly with the slab lying on it, a slab manipulator which can be moved transversely is arranged which synchronously transmits a running gear frame overhanging the length of the grinding table with its inside on each end face having driven slewing frame, wherein the slewing frame is connected to each other via a lower and an upper, raised and lowered in the slewing frame lifting beam and wherein the one lifting beam with a slab surface under cross and the other lifting beam is provided with the opposite slab surface cross-supporting elements.
  • these are preferably articulated via hydraulic cylinders to the slewing frame and advantageously arranged in guides the slewing frame.
  • a preferred proposal of the invention provides that the lifting traverses are independently raised and lowered. In the receiving position thus needs only one of the lifting beams lowered and then driven from the side under the slab until it rests with its narrow side to an advantageously formed on the lifting traverse stop. The lower lifting beam is then raised while the upper lifting beam is lowered later to clamp or clamp the slab. After the turning process, the lower lifting beam takes over the function of the upper lifting beam, and then vice versa.
  • the turning of the slab can be advantageously achieved in that the slewing frame are formed with a rotary bearing actuated by a rotary bearing to the chassis frame.
  • a rotary drive is preferably a geared motor used.
  • the lifting traverses are provided with offset in traverse longitudinal direction to each other, zinc-like support rods are provided as support elements.
  • the recording and clamping or clamping of the slab takes place here with linear contact surfaces and over the length of the slab up and down offset support elements.
  • the invention further provides that the support rods are overlapping each other to over half of the maximum width of the slab and beyond the minimum slab width outgoing.
  • the width of such a slab to be handled may be, for example, 800 mm to 1,700 mm with a length of 5,000 mm to 12,000 mm and thicknesses of 150 mm to 240 mm.
  • the tine-like support rods of the lower and upper lifting traverse thus have from the outset on such a length that in any case a occurring in the intended width spectrum slab can be safely picked up, clamped and turned.
  • Two grinding machine units which are in Fig. 1 not shown and only indicated by I and II, closes in the direction of material flow according to arrow 1 for handling during grinding of slabs 2a and 2b, of which the slab 2a a maximum width and thickness (see. Fig. 6a ) and the slab 2b a minimum Width and thickness (cf. Fig. 6b ), a cross conveyor 3 on.
  • This has one with wheels 4 on an anchored to the foundation 5 substructure 6 of concrete laid rails 7a, 7b in the direction of the double arrow 8 transverse to the grinding machine units I and II movable slab manipulator 9 (see. Fig. 3 ).
  • the transverse conveyor system 3 according to the embodiment of Fig. 2 and 3 has at a distance parallel to each other lying next to several stationary shelves 10a, b, c and d, extending between each of the two outer slab trays 10a, 10b and 10c, 10d bottom rail pairs 11a, 11b in the material flow direction 1.
  • the slab manipulator consists of a subframe 6 with the two rails 7a, 7b spanning, circumferentially closed chassis frame 13 (see Fig. 1 and 3 ).
  • this slab clamping and lifting means 14 designed as a lower lifting cross-member 14a and upper lifting cross-member 14b, provided by means of hydraulic cylinder 15 in guides 16 (see. Fig. 4 ) are independently raised and lowered.
  • the slab clamping and lifting means 14 are also rotatably formed for turning a picked and clamped slab 2a and 2b, including the lower and upper lifting traverse 14a and 14b at their two ends in each supported by the chassis frame 13 slewing frame 17a, 17b are stored (see. Fig. 3 ).
  • the slewing gear frames 17a, 17b are provided with a ball slewing connection 19, which can be actuated by a rotary drive 18, in particular a geared motor, as in FIG Fig. 5 indicated schematically formed to the chassis frame 13.
  • the rotation range of the slab manipulator 9 is in the Fig.2 and 5 as dash-dotted circle 20 indicated (see also Fig. 4 ).
  • the lower and upper lifting traverse 14a, 14b is provided with tine-like support rods 21 a and 21 b as support and takeover elements.
  • the support rods 21a of the lower lifting cross-member 14a are seen offset in traverse longitudinal direction relative to the support rods 21b of the upper lifting beam 14b offset (see. Fig. 1 ).
  • the slab 2a or 2b is either on a grinding table 12a, 12b or on a stationary tray 10a, b, c or d.
  • the slab manipulator 9 can run over the stationary slab shelves 10a to 10d and the grinding tables 12a, 12b as desired on the substructure 6 and thus perform a desired distribution of the slabs.
  • the slab manipulator 9 with opened lifting traverses 14a, 14b is moved in a parallel position to either a stationary tray 10a to 10d or to a grinding table 12a, 12b, as in FIG Fig. 1 shown in position to the grinding table 12b.
  • the slab manipulator 9 has run over a grinding table or a stationary slab plant and is in a lateral parallel position, is, as the example of the Fig. 6 and 6a 6b, the lower lifting beam 14a lowered from the dashed, raised position, the slab manipulator then under the on in the embodiment of the Fig. 6 on the stationary tray 10c raised slab 2a and 2b driven, as illustrated by solid lines.
  • the transverse travel of the slab manipulator 9 for reaching under the slab is stopped as soon as the slab 2a or 2b hits a stop 22 of the lifting traverse 14a.
  • the lower lifting beam 14a with the overlying slab is then raised, and then the upper lifting beam 14b is lowered for clamping the slab, as in FIG Fig. 6a for a slab 2a with maximum dimensions and in Fig. 6b for a slab 2b with minimal dimensions.
  • the slab manipulator 9 is moved to a turning position (W) offering sufficient clearance, as in FIG Fig. 2 between the two stationary slab deposits 10b and 10c (cf. Fig. 5 ) indicated.
  • the lower lifting beam 14a assumes the function of the upper lifting beam 14b and vice versa.
  • the thus turned slab 2a or 2b can be stored by the slab manipulator by transversely on the stationary slab trays 10a to 10d for temporary storage or immediately positioned on a grinding table 12a or 12b, the slab with the surface for grinding machining in the grinding machine unit I or II retracts.
