- the object of the invention is to provide a device of the type mentioned, with which a smallest possible radius of curvature can be reduced in the course of the exchange guides, without thereby the practical applicability of the device is adversely affected.
- Another advantage of the invention is to reduce a maximum required pull-out force of a lifting device for lifting a segment in the course of curved alternating guides. This causes the lifting device to be dimensioned smaller with the same weight of the segment.
- segment manipulator has at least one laterally arranged and articulated rocker.
- the segment manipulator has at least one laterally arranged and articulated rocker, whereby a kinking of the segment manipulator in the alternating guides with consistently good mechanical properties (ie, high stability and / or high rigidity) is achieved.
- the maximum distance between two rigidly connected guide elements on one side of the segment manipulator is reduced to approximately one half, which in turn allows a reduction of the smallest possible radius of curvature in the course of the alternating guides.
- Investigations have further shown that such a executed segment manipulator also allows a reduction of the maximum pull-out force of a lifting device for lifting the segment in the course of curved alternating guides.
- the lifting device typically designed as a crane
- the hall height can be reduced due to the lower radii of curvature and reduced for threading vertical length of the exchange guides.
- an upper part of the segment manipulator is connected via a respective joint with a horizontal axis of rotation with a laterally arranged rocker.
- Joints with a horizontal axis of rotation are advantageous because they are simple, inexpensive and robust.
- a joint is formed by a pin, a bearing bush and a recess in the associated rocker.
- Particularly low extraction forces of the lifting device can be achieved if the joint is used as a lubricated joint with a lubricant supply, e.g. a fat grease, is formed.
- a lubricant supply e.g. a fat grease
- the segment manipulator is guided in each case via an alternating guide by three guide elements per side, a guide element being arranged in the upper region, one in the middle region and one in the lower region of the segment manipulator.
- the segment manipulator is divided by the joints in an upper part and two wings, wherein the upper part on both sides in each case two guide elements and the two wings are each assigned a guide element; or the upper part on both sides in each case a guide element and the two rockers are each assigned two guide elements.
- the guide elements as guide wheels.
- sliders or sliding jaws possible.
- the change guides associated with the segment are formed from two guide rails having a spacing.
- Guide rails are simple and robust mechanical elements and can be connected in place with high accuracy, e.g. welded, be.
- each side of the segment is over at least one, preferably two, lateral ones Trunnion releasably connected to a segment support, the latter being connected to the joint of the segment manipulator.
- a further advantageous embodiment is to execute the rocker of the segment manipulator with a locking device and an actuating device, preferably a hydraulic cylinder, wherein the locking device blocks a relative movement of the segment support relative to the rocker and the actuating device allows a relative movement of the segment support relative to the rocker.
- the locking device blocks a relative movement of the segment support relative to the rocker
- the actuating device allows a relative movement of the segment support relative to the rocker.
- Locking device locked When unthreading the segment, however, it may be advantageous to rotate the segment holder relative to the rocker so that the segment can be offset from an adjacent segment. By means of this embodiment, the expansion is greatly simplified.

- the strand guide includes the
- Segment manipulator 8 is supported, this being guided in the guide rails formed as a change guides 6.
- the transfer of the force for lifting the segment takes place from the lifting device to a cross-member, from the cross-member to a link chain, from the link chain to the segment manipulator and from there to the segment.
- FIGS. 2 and 3 show a segment 2 with an associated segment manipulator 8, a link chain 9, a traverse 10 which can be connected to a lifting device 19 and the alternating guides 6 designed as guide rails.
- the segment manipulator 8 is divided by the joints 11 in an upper part 8a and two wings 12.
- the upper part 8a of the segment manipulator 8 which is designed as a U-shaped frame consisting of a crosshead and two legs, is connected in each case via a joint 11 with a horizontal axis of rotation IIa, each with a laterally arranged rocker 12.
- the joints 11 are located approximately in the middle of the vertical longitudinal extent of the segment manipulator 8.
- the segment manipulator 8 is guided via three guide elements 14 designed as guide wheels in an alternating guide 6; Each guide element is located in the upper region, one in the middle region, ie in the region of the joint 11, and one in the lower region of the segment manipulator 8.
- Each side of the segment 2 is detachably connected via two laterally arranged support pins 13 with a segment holder 17, the latter being connected to the hinge 11.
- the segment holder 17 is thus also rotatably mounted about the hinge 11, wherein in the normal case the rotational movement of the segment holder relative to the rocker 12 by means of a
- Locking device 18 for example, a locking pin is locked.

- the link chain 9 is connected to the cross member 10, wherein by means of the traverse the force for raising or lowering the Segment 2 is transmitted from the lifting device 19 to the link chain 9 and subsequently to the segment manipulator 8 and the segment 2.
- the largest distance between two adjacent, rigidly connected guide elements 14 is reduced on one side to about half. This makes it possible to considerably reduce the smallest possible radius of curvature in the course of the alternating guides 6 and / or the maximum pull-out force of the lifting device 19 in the course of curved alternating guides.
- a reduction of the smallest possible radius of curvature of the exchangeable guides 6 allows a more compact, i. lower, continuous casting machine; a reduction in the maximum extension force of the lifting device 19 allows the use of a lifting device with a lower maximum load capacity with the same weight of the segment.
- FIG. 4 two swung-out positions of the rocker 12 of the segment manipulator 8 are shown about the hinge 11 with horizontal axis of rotation, wherein a guide member 14 in the central region, i. in the region of the joint 11, and one in the lower region of the rocker 12 is arranged.
