Definitions

  • the invention relates to a device on a support and guide frame for a continuous casting installation, in particular for a steel slab continuous casting installation, with the strand supporting roller tracks on two opposite sides, one of the two roller tracks on a first supporting structure and the other roller conveyor on a second supporting structure are arranged, which can be tensioned against the first structure by means of tie rods and connected to the first structure or detachable from the first structure.
  • the invention aims to avoid these difficulties and has as its object a device rt a support and guide structure of the input A described in the introduction which enables an easy connection and disconnection of the tie rods to and from the support structure, said to-handle parts have to be manipulated only slightly for the production and for releasing the connection.
  • a bayonet connection is provided as the connection between the supporting structure and the tie rod, in which a disc having at least one recess is arranged on the supporting structure, into which a tie rod head having a lateral extension corresponding to this recess can be inserted and the tie rod head or the disc can be rotated into a fastening position axially fixing the tie rod.
  • the disks can be rotated and are each inserted into a cavity of the supporting structure that can be closed to the outside with a cover plate.
  • holes are advantageously provided on the circumference of the disks, into which an actuating lever or a locking pin arranged on the cover plate can be inserted.
  • the washers of the bayonet connections are expediently provided on the first supporting structure of a supporting and guiding frame, in which actuators for adjusting the second supporting structure are connected on the one hand to the second supporting structure and on the other hand to the tie rods in such a way that the tie rods on the first Support structure are releasably attached and after releasing the connecting means from the position connecting the supporting structures can be removed from the first supporting structure by means of the actuators and retracted into a retracted position in the second supporting structure.
  • a separation of the first structure from the second one is special simple and quick way possible.
  • FIG. 1 shows a view of a support and guide frame in the direction of the longitudinal axis, partly in section
  • Fig. '2 shows a section on a smaller scale according to line II-II of Fig. 1 .
  • 3 and 4 show a detail of FIG. 1 on an enlarged scale in section, the section being taken along the line III-III of FIG. 1.
  • a strand 3 is supported and guided between the roller conveyors 1 and 2.
  • the rollers 4 of each of the roller tracks are inserted with brackets 5 in bearing blocks 6, which are fastened to side members 7, 8.
  • four brackets 5 are provided in the embodiment shown, which are distributed over the longitudinal extent of the rollers.
  • the longitudinal members 7 of the lower roller conveyor are fastened to cross members 9 and, together with the cross members, form a first support structure 10.
  • the longitudinal members 8 of the upper roller conveyor are also mounted on cross members 11 and together with these form a second support assembly 12.
  • the supporting structure 10 is rigidly fastened to the sides of the ends of the rollers 4, hollow struts 13 which have a flange 14 at their upper end.
  • One end 15 of a cross member 11 of the second supporting structure 12 rests on this flange, u. between either directly (with a minimum distance between the roller conveyors) or with washers (with the distance between the roller conveyors exceeding the minimum distance, Fig. 1).
  • the cross members 11 of the second supporting structure 12 are penetrated at both ends 15 by tie rods 16 which are aligned with the cavity 17 of the hollow struts 13 and can be inserted into the cavity.
  • the ends of the tie rods 16 projecting beyond the cross members of the second supporting structure are each provided with a collar 18.
  • This collar is supported by a relief device 19 either directly or with washers 20 interposed against one end 15 of the cross member 11 of the second supporting structure 12.
  • a girder 22 is articulated to an extension 21 of the tie rod, one girder connecting two tie rods 16, each of which is provided at the ends 15 of a cross member 11.
  • an approximately parallel to it pressure medium cylinder 24 is provided, which is articulated on the one hand on the carrier 22 and on the other hand on the cross member 11 of the second structure.
  • the pressure medium cylinders 24 (another actuating device, for example a rotatable spindle etc. could be provided in their place) are each located between the tie rods 16.
  • the relief device 19 has two bushes 25, 26 which form a thread with corresponding helical sliding surfaces.
  • One of the sleeves 25, 26 is rotatable relative to the other sleeve, u. between by means of a pressure medium cylinder 27 articulated on one of the two bushes, which are arranged on mutually opposite tie rods 16, whereby the distance of the outer bearing surfaces 28, 29 of the sleeves 25, 26 between cross member 11 and collar 18 of the respective tie rod 16 changes can be.
  • these bushes 25, 26 it is thus possible to tension a cross member 11 of the second supporting structure 12 against the struts 13 and thus against the first supporting structure 10, u. between.
  • tie rods fixed in the first supporting structure, or to separate the two supporting structures 10, 12 from one another.
  • the tie rods 16 are fixed to the struts 13 by means of a bayonet connection 30, which is designed as follows:
  • a disk 31 is rotatably inserted into the cavity 17 of the struts 13.
  • the cavity is delimited at the top and bottom by a plate 32, 33 in each case.
  • the disc 31 has an oval, centrally arranged recess 34 through which the tie rod head 35, which is designed as a hammer head-like extension 37 arranged at the tapered end 36 of the tie rod 16, can be passed.
  • the disk 31 can be rotated by means of an actuating lever 38 shown in FIG. 4, which can be inserted in bores 39 which are arranged on the circumference 40 of the disk 31.
  • a pin 42 which projects into a peripheral groove 41 of the disk 31 and is mounted on the strut 13, is provided as the twist stop.
  • the cavity 17, in which the disc 31 is inserted, is closed to the outside by means of a removable cover plate 43.
  • a locking pin 44 projecting into the cavity 17 is fastened, which protrudes into one of the bores 39 of the disk 31 when the cover plate 43 is mounted on the strut 13.
  • the cavity 17 in which the disc 31 is located is advantageously filled with grease.
  • the function of the device is as follows: If the second supporting structure 12 is to be lifted off the first supporting structure 10, the relief devices 19 are first actuated, that is to say the tensioning of the supporting structures is released, after which the actuating lever 38 is removed into one of the bores 39 of the disks 31 after the cover plates 43 have been removed is used and the disks from the fastening position A, which is shown in Fig. 3, are rotated into the release position B shown in Fig. 4. Since a pivoting of the actuating lever 38 by 90 ° is not possible, the actuating lever 38 must be inserted one after the other into the bores 39 of the disks 31 in order to be able to turn the disks 31 by a full 90 °.
  • the procedure is as follows: First, the tensioning of the supporting structures 10, 12 is released by actuating the relief devices 19. The cover plates 43 are then removed and the disks 31 are rotated into the release position B with the aid of the actuating lever 38. With the help of the pressure medium cylinders 24, the tie rods 16 are retracted until the hammer head-like projections 37 are located above the disk 31. After turning the disks 31 back into the fastening position A, the tie rods 16 can be lowered again until they sit on the disks 31.
  • the cross members 11 can be raised further with the aid of the pressure medium cylinders 24.
  • An extension 45 below the hammer head-like extension 37 serves to center the tie rods 16 in this raised position; it is also advantageous when inserting the tie rods into the struts 13.
  • cover plates 43 To release the tie rod fastening from the first supporting structure, it is only necessary to disassemble the cover plates 43 and manipulate an actuating lever 38. Both parts, cover plate and actuating lever, can be designed very easily, so that the work associated with loosening or fastening the tie rods on the first structure can be carried out in a simple manner.
  • the invention is not limited to the embodiment shown in the drawing, but can be modified in various ways. It is thus possible to rigidly arrange the disks 31 in the struts 13 and to mount the tie rod head 35 rotatably. Furthermore, a largely arbitrary design of the hammer head-like approach of the tie rod and the corresponding recess in the disk is conceivable, it only has to be ensured that the tie rod head engages behind part of the disk and is large enough to accommodate the tensile forces that occur.
  • the device according to the invention can not only be used advantageously in a support and guide frame with a large number of tie rods, as shown in FIG. 2, but can also be provided in a support and guide frame with only four tie rods arranged at the corners thereof, for example on a straightening unit.
