Definitions
- the invention relates to a method and an apparatus for handling slabs, in particular produced by continuous casting, the surfaces of which are ground in a rolling train before being rolled, the slab being reciprocated on a reversing grinding table under a grinding unit of a grinding machine unit arranged in a grinding booth is, 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 fed, the slab is removed after turning from the turning device and spent with the unprocessed, other surface overhead on the grinding table , which then re-enters the grinding booth for processing this surface.
- the invention is therefore an object of the invention to provide a significantly simplified method and apparatus for handling the grinding of continuously cast slabs with a simultaneously greatly reduced structural complexity.
- This object is achieved by a method according to the invention in that the slab is taken 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 invention 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 closed menklemm- and -hebesch 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 Edition of the 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 closed menklemm- and -hebesch and the slab manipulator is moved with the clamped slab in
- 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 in particular for carrying out the method, provides that in the outlet region of at least one grinding machine unit, in which the grinding table is moved linearly with the resting slab, a slab manipulator movable transversely thereto is arranged, which has a running gear frame overhanging the length of the grinding table having on each end inside, synchronously driven slewing frame, wherein the slewing frames are 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 with the opposite slab surface is provided overarching support elements.
- the slab After receiving the slab between the two lifting trusses that carries a support element, the slab, while it is positioned clamped by adjusting the other support member or clamped.
- 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. As 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 bars 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.
- Fig. 1 is a layout of a two spaced apart side by side
- Fig. 3 as a detail of Figures 1 and 2 in a side view of a slab manipulator as a cross-transport and slab turning device.
- Fig. 5 is a side view of a more detailed illustration of the slab manipulator of Fig. 4;
- FIG. 6 is a schematic side view as a detail of the slab manipulator whose upper and lower lifting crossbar when passing over a slab occupied with a slab grinding table or a stationary slab deposit and after lowering the dashed lower Hebetraverse when receiving the slab;
- FIG. 6a shows a representation corresponding to FIG. 6 after picking up and lifting as well as clamping a slab with maximum width dimension by means of the lowered upper lifting beam;
- Fig. 6b is a representation corresponding to Fig. 6a for a slab with a minimum width and thickness.
- a transverse conveyor system 3 at. 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 transversely to the grinding machine units I and Il movable slab manipulator 9 (see Fig .. 3).
- the transverse conveyor system 3 has a plurality of parallel spaced adjacent stationary shelves 10a, b, c and d, wherein between each of the two outer slab trays 10a, 10b and 10c, 10d bottom rail pair pairs 11a, 11 b in the material flow direction 1 extend.
- grinding tables 12a, 12b are moved, which convey a machined or sanded slab in the grinding machine unit I or Il or convey out to turn the slab for grinding the other surface.
- the slab manipulator consists of a subframe 6 with the two rails 7a, 7b spanning, circumferentially closed chassis frame 13 (see Figures 1 and 3).
- slab clamping and lifting means 14 designed as lower lifting cross member 14a and upper lifting cross member 14b, are provided which can be raised and lowered independently of one another by means of hydraulic cylinders 15 in guides 16 (compare FIG.
