Definitions

  • the invention relates to a device for exchanging support or drive rollers of a continuous casting installation with a strand guide having two roller conveyors lying opposite one another, the device comprising a carriage which can be moved between the roller conveyors for transporting a roller to and from or for storage in one of the roller conveyors , which is equipped with the roller-receiving roller seats and has a device for moving a roller from its storage location to the carriage or from the carriage to the storage location.
  • the support and drive rollers in machine parts represent particularly highly stressed machine parts. Their service life is relatively short compared to other machine parts in machine lines. For this reason, the support and drive rollers often have to be replaced with new or reconditioned rollers in the course of maintenance work. If support or drive rollers fail, the defective rollers should be replaced within a very short period of time to avoid long downtimes.
  • a device of the type described is known, for example, a roll installation in the continuous caster is carried out in such a way that the roll to be installed is placed in a roller seat of the slide, transported with the slide between the roller tracks and by means of a is guided on the carriage or to the roller tracks fastened laterally guide on which a olle end to the respective R of the roll to be incorporated in engagable driver, is inserted into the bearing of the roller conveyor.
  • the attachment of the lateral shifting devices requires an additional expenditure of time and an operator has to climb into the side of the strand guide up to the role to be exchanged in order to attach the shifting device. This is a difficult operation because of the small space to the side of the strand guide.
  • the invention aims at avoiding these difficulties and has as its object to provide a device of the type described in the introduction with which the time required for a roll change can be substantially reduced, with which the change process is simplified overall and with which in particular the space to the side of the strand guide for changing rolls is not required.
  • roller seats are movably arranged on the carriage transversely to the longitudinal direction of the rollers and can be moved by means of an actuating device from a transport position retracted in the carriage into an engagement position protruding from the carriage.
  • the roller seats are expediently fastened to swivel arms articulated on the slide.
  • roller seats are expediently pivotably attached to pivot arms which are articulated on the slide and provided with an extension which, in the retracted transport position of the roller seat, touches a stop of the pivot lever and in the engagement position of the roller seat projecting from the slide on the roller adjacent to the roller to be removed Role.
  • a preferred embodiment is characterized in that the roller seats are pivotally attached to swivel arms articulated on the sled and are each provided with an extension which bears against a stop of the sled in the transport position of the roller seat and that a pawl is pivotally attached to the swivel arm, which on the one hand, one end of it rests with a shoulder on the extension of the roller seat and, at the other end, it rests on a stop arranged in the slide, the pawl always holding the roller seat with its opening that receives the roller directed towards the roller, so that the device can also be used entirely roller conveyors lying particularly closely opposite one another, in which the rollers are also arranged closely adjacent, can be used.
  • roller seats are designed as elastically deformable resilient clamps encompassing the rollers.
  • the roller seats have between the rollers of the roller conveyor feasible, behind the rollers, swiveling latches, which can be swiveled about an axis arranged perpendicular to the roller conveyor from a position parallel to the roller axes into a position transverse to the roller axes, whereby it is possible to securely lock the roller-Jen to the lower roller conveyor capture and hold in the role seat.
  • the swivel arm is expediently designed as an angle lever, on one lever arm of which the roller seat is mounted and on the other lever arm a pressure medium cylinder articulated on the slide is articulated. is consolidated.
  • FIG. 1 shows a longitudinal section through part of a schematically illustrated strand guide, in which a carriage according to a first embodiment for replacing the one seated on the inside or top of the strand guide Roles is shown.
  • Fig. 2 shows a view of the carriage partially in section according to the arrow II of Fig. 1 (omitting the roller tracks).
  • 3 shows, in a representation analogous to FIG. 1, a further embodiment of the device according to the invention for exchanging the rollers arranged on the outside or underside of the strand guide, partly in section
  • FIG. 4 is a view of the carriage in the direction of arrow IV of FIG 3 partly in section.
  • 5 shows a further embodiment in a representation analogous to FIG. 1.
  • a carriage 6 the height h of which is somewhat less than the roller conveyor Stand d, is articulated with a dotted line 7 and can be moved together with this between the roller tracks in the longitudinal direction.
  • the carriage 6 has two roller seats 8, 9 lying one behind the other, which are designed as elastically deformable, resilient clamps 10 encompassing the rollers.
  • Each of the roller seats is immovably attached to a pivot arm 11 articulated on the slide 6, but, as is shown in detail on the lower roller seat 8, can be pulled off the pivot arm 11 by loosening a bolt 12.
  • the swivel arm is designed as an angle lever which is articulated on the slide at the intersection of its lever arms 13 ', 13 ".
  • One of the lever arms 13' carries the roller seat 8 or 9; the other lever arm 13" is on a piston of a pressure medium cylinder 14, which on Carriage 6 is articulated, articulated.
  • the roller seats can be pivoted from a transport position A retracted in the carriage (cf. upper roller seat in FIG. 1) into an engagement position B protruding from the carriage (cf. lower roller seat in FIG. 1) or vice versa.
  • the carriage itself is formed from side walls 15, which are connected to one another via a cross member 16 and tubes 17.
  • two swivel arms 11 are arranged parallel to each other and connected to each other by means of a tube 18 for the purpose of synchronism.
  • the side cheeks 15 of the carriage are connected to the latter via the lower tube 17, which on the one hand passes through the side cheeks 15 and on the other hand, brackets 20 welded to a crossmember 19 Traverse 19 articulated.
  • stops 20 are provided on the side cheeks 15.
  • the resilient brackets 10 enable a safe and particularly simple change of the roles of the inner or upper strand guide track 1. If the roles of the outer or lower role track 2 are to be changed, a precaution must be taken that the roles used in the role seats are not accordingly of their own weight falling out of the reel seats. An embodiment in which this is realized is shown in FIGS. 3 and 4.
  • a fork-shaped roller seat 23 is articulated to a swivel arm 24 which is pivotally mounted about the axis 26 in a carriage 25.
  • the swivel arm 24 is in turn designed as an angle lever and can be actuated by means of a pressure medium cylinder 27 which is articulated on the one hand on a lever arm 28 of the swivel arm and on the other hand on the slide 25.
  • the fork-shaped roller seat 23 has an extension 29 which, in the engaged position B of the roller seat 23, bears against the roller 3 which is adjacent to the roller 22 to be replaced and in the transport position A of the roller seat 23 bears against a stop 30 of the swivel arm 24. This extension 29 thereby causes a precise alignment of the fork-shaped roller seat 23 with the fork opening to the roller 22 to be exchanged, as a result of which the fork-shaped roller seat 23 can also be easily pivoted into engagement position B between closely adjacent rollers 3.
  • the forks of the fork-shaped roller seat are formed by swiveling bars 31, 32 engaging behind the rollers.
  • the bolts 31, 32 are moved from a position parallel to the roller axes 3 'into a position transverse to the roller axes, as shown in FIG. 3 with dash-dotted lines a linkage which can be driven by a preferably hydraulically actuated pressure medium cylinder.
  • two hydraulic pressure medium cylinders 33 are provided, which are articulated with their piston rods on the pivot lever 34.
  • These pivot levers 34 are articulated on the one hand to the slide 25 (at 35) and on the other hand articulated on the lever linkage, which consists of a first push rod 36, an angle lever 37, another push rod 38 and a lever 39.
  • One of the bolts 31, 32 is fastened to the angle lever 37 and the lever 39.
  • a connecting rod 40 is provided between the opposite pivot levers 34, as is indicated in FIG. 4 by dash-dotted lines.
  • this embodiment is similar to that of the embodiment shown in FIGS. 1 and 2. It is only necessary to fix the roller in the roller seat 23 after it has been inserted into the roller seat 23 or has been laterally embraced by the roller seat 23 by pivoting the bolts 31, 32 - by actuating the pressure medium cylinders 33.
  • roller seat 41 which is likewise designed here as a resilient bracket 10, is arranged in an articulated manner on a swivel arm 43 (at 44) articulated in the carriage 42.
  • the roller seat 41 has an extension 45 which is in the transport position A of the roller seat 41 abuts a stop 46 of the carriage, as shown in Fig. 5 with full lines.
  • roller seat 41 The exact alignment of the roller seat 41 during this pivoting movement is effected by an angular pawl 47 which is pivotally attached to the pivot lever 43 on the axis 48.
  • An arm 49 of the pawl 47 always presses against the extension 45 of the roller seat 41 with an extension 50, ie also during the pivoting movement, and the other arm 51 of this pawl 47 bears against a roller 52 which is rotatably mounted in the slide housing.
  • the extension is always held parallel to the roller tracks 1, 2 or parallel to the top or bottom of the carriage 42.
  • a pressure medium cylinder 53 serves to move the swivel arm 43.
  • any drive device can also be provided as an actuator for the swivel arms of the roller seats.
  • the roller seats also do not necessarily have to be attached to swivel arms, they can also be moved from the slide into the engagement position and back by other adjusting means, for example by means of jack-like structures, by means of adjusting spindles, etc.
  • carriages according to different embodiments can be combined with each other. This is necessary if, for example, you want to remove damaged rollers from the upper and lower roller conveyor in one operation and replace these defective rollers in the upper and lower roller conveyor in another operation.
