Definitions

the invention relates to a device for changing a segment of an arc formed from a plurality of segments of a strand guide for a continuous casting machine, on which liquid metals, in particular liquid steel, are poured, the segments being detachably fastened individually in segment carriers and a detached segment in a guide by means of a chain, a first traverse and a crane can be lifted up to the casting platform.
the segments are used in particular on continuous slab casting machines and must be removed at intervals for repairs or / or maintenance work and brought to a remote workshop.
a segment changing device is described in DE 29 08 476.
the segments carry extension rollers that run in stationary guides that extend up to an arc radius and are arranged radially to the course of the arc.
a movable, up to the arc radius, pivotable about a horizontal axis inner track section is formed, which can be selectively adjusted to a fixed guide.
Retractable locking devices are provided for the aligned positioning and support of the track section on the fixed guides.
the object of the invention is to improve the accessibility to the segments of such continuous casting machines, the weight of the segments, which can be up to 601 and more, to be taken into account.
the object is achieved in accordance with the invention; that a segment is held for removal or installation by means of support pins engaging in angle brackets and the angle brackets are connected by means of a second cross member.
improved inspection with free access to the segments can be achieved on both sides of the continuous casting machine.
Another advantage is the load-bearing capacity of such a system in the required order of magnitude with a free arch interior and consequently improved accessibility to the segments on the outer and inner arch.
Accessibility is further improved by arranging an inspection between the segments and the strand guide.
the device can also be designed in such a way that, on both ends of the strand guide, each in parallel, following the course of a guide, removal chains are guided in an upper rail and the removal chains are connected to one another at the end on the crane side by means of the first crossbeam which carries the crane loops are connected.
the high load can be transported more easily in the rails in that the removal chains can each be moved in the rails by means of guide wheels rotatably mounted in the chain links.
the removal chains are each connected on both sides to the second cross member for receiving a segment by means of fastening bolts.
the removal chains are connected to the segment at the end on the segment side by means of the second cross member, which forms angle brackets and has the fastening bolts.
one of the angle supports serves as a torque support on the side opposite the support roller drive side and that the segment can be suspended on this side by means of at least two spaced support pins and a bolt and on the other side by means of a bolt.
the advantage is that the segment can be guided in the direction of the rail during installation and removal.
the double-supported version takes into account the large vertical force components, particularly in the upper area of the continuous casting machine when changing segments, for segment weights up to 60 l.
Another improvement is that an articulated threading roller is provided on the bottom chain link of each expansion chain.
the chains are easier to thread into the guide rails from the casting platform by means of the crane.
Another embodiment is that free access areas with free access to the segments are provided on both sides of the strand guide. This favors maintenance and monitoring of the system components.
the inspection areas can have a minimum width of 500 mm, so that even smaller loads can be carried up to the segments.
Fig. 1 is a side view of the continuous caster with the course of the guide and its rails 2 is a front view of the changing device with a segment
FIG. 3 shows the side view belonging to FIG. 2 (drawn without a segment)
FIG. 4B shows a detail C from FIG. 4A
Fig. 6 the top view belonging to Fig. 5.
the continuous caster is seen from the side, so that the curved course of the strand guide 2 is visible, the segments 1 being installed in the operating position.
the guides 4 for the segment carriers 3 consist of rails 4a arranged in pairs and run from the casting platform 7 with a continuous casting mold 7a to the region of the end positions of the segments 1.
An upper rail 4a extends in an arc up to the end position and a lower rail 4b to behind the end position.
the rails 4a, 4b end together in the horizontal part of the strand guide 2.
the device for changing a segment 1, which forms the arc or partial arc of the strand guide 2 for a continuous casting machine in a plurality, on which liquid metals, in particular liquid steel, is poured, has segments 1 which are detachably fastened in segment carriers 3.
a detached segment 1 can be lifted up to the casting platform 7 in the guide 4 by means of a chain pair 5 and a crane 6.
FIG. 2 On the two end faces 8a and 8b of the strand guide 2, in each case parallel, are adapted to the course of the strand guide 2, Removal chains 5a and 5b each guided in a rail-like guide 4.
the individual chains 5a and 5b are connected to each other at the crane-side end 9 by means of a first 'traverse 10, which has at least one crane loop. 11
the removal chains 5a, 5b are kept stable and in parallel by means of spacers 12.
Each single chain 5a, 5b consists of chain links 13 (of the type 990 x 380), with a bolt 14 and guide wheels 15.
the guide wheels 15 run in the rails 4a.
the chain links 13 have side plates
the chain links 13 of the expansion chains 5a, 5b are each held together by the bolt 14.
the expansion chains 5a, 5b form at one end on the segment side
Screws 19 and further bolts 20 are provided in guide strips 21 within the angle supports 10b and 10c.
the segment 1 engages in these guide strips 21 by means of trunnions 22.
the left angle support 10b is also designed as a torque support 23 opposite the support roller drive side 24.
two support pins 22 engage in the torque support 23 and a single support pin 22 on the support roller drive side 24 of the right angle support 10c.
the double-supported version on page 25 takes into account the large vertical force components that occur in the upper area of the continuous casting machine when changing segments, which arise with segment weights of, for example, 601.
a threading roller 26 which is articulated on an axis is connected to the lowest chain link 13 of each removal chain 5a, 5b.
the crane 6 engages with the crane hook around a bolt 27, which is supported by means of an axle holder 28.
the lower, second crossbeam 10a is connected to the expansion chain 5a (5b) by means of the fastening bolt 18.
the threading roller 26 is pivotable about the axis.
the guide wheel 15 can be seen rotatably mounted within the chain link 13.
the removal chains 5a, 5b are each connected to the second crossbeam 10a by means of the fastening pin 18, a cover 29, a lubrication 30 and a cylinder head screw 31 forming the counter bearing.
the guide wheel 15 is mounted on a shaft journal 32 which is guided by means of bushes 33.
the bearing is closed by a cover 34.
a screw 35 for connecting the threading roller 26 is connected to the plate 36.
Fig. 5 shows the continuous caster in elevation with the casting platform 7. Due to the location of the support roller frame 2 in the segments 1 and the mutual arrangement of single chains 5a and 5b on the side 25 and the support roller drive side 24, a variety of free inspection -Faces 38 with free access to the segments 1 created.
