Definitions

  • the invention relates to a device for the transport of roll stands or roll stand groups, in which the roll stands can be moved out of or into a position in the rolling line on a platform provided with castors on rails lying transversely to the rolling line of a roll train and can be brought into it and outside of it Rolling line transversely to these rails rails can be transported or removed.
  • Devices of this type are used to quickly change the roll stands or roll stand groups.
  • the rolling stands are replaced after they are brought out on the rails lying transversely to the rolling line and removed on the rails lying transversely to these rails by other rolling stands provided on the same rails, which are inserted in their place in the rolling line, and can be removed after they have been removed serviced at designated equipment locations and made available for reuse.
  • the platform receiving a roll stand group is applied to a second platform after it has been moved out of the rolling line on the rail lying transverse to the rolling line of the rolling train the corresponding rail sections lying in the same roller plane are arranged and fixed there.
  • This second platform in turn rolls across to the rails mentioned rails, the roller level is correspondingly lower.
  • This device has the disadvantage that two complete platforms are required for the transport of the rolling stands, of which the second has to take up the additional weight of the first platform, the further disadvantage that the lower rolling plane of the rails on which this second platform is moved, requires a corresponding channel-like pit below the rolling mill floor, which must be led along the operating side of the entire rolling mill and on to the equipment location of the roll stands.
  • the pit therefore often requires special covers, which do not hinder the operation of the roller mill and to avoid the risk of accidents, which must be removed when the platform passes through and then replaced again. Additional fixing devices are required for the transport of the first platform on the second platform.
  • the invention has for its object to improve the generic devices so that the disadvantages mentioned are avoided and the technical and operating costs are reduced.
  • rollers of the platform receiving the roll stands are supported in supports which can be inserted and fixed in accordance with the respective course of the rails in such a way that they can be rotated about vertical axes connected to the platform.
  • each of the rails can have a rail turntable known per se at its intersection points with the transverse rails, this turntable being individually or jointly drivable and fixable in certain rotational positions.
  • this turntable being individually or jointly drivable and fixable in certain rotational positions.
  • lifting motors are advantageously arranged on the platform and can be supported against the supporting floor of the roller train or the rails.
  • the platform can be raised once to make it easier or possible to rotate the carriers of the castors or the rail turntables, which would require a disproportionately large amount of drive, especially heavy roll stands or roll stand groups the position of the platform in the roller mill can be raised, for example, into the rolling line with the aid of the lifting motors and adjusted according to the respective position of the roll gap by roller sets of different diameters. If groups of hydraulically and mechanically working lifting motors are arranged together, the required stroke of the platform can first be retracted with the help of the hydraulically working lifting motors and then fixed and locked with the help of the mechanically working lifting motors. Finally, like the invention provides, can be arranged on the platform with the castors coupling drives, which allow the platform to move independently on the rails in the different directions.
  • pairs of such carriers 3 with castors 4 are arranged on the two outer sides of the platform 1; the driving rollers 4 of these carriers are not driven, while two further pairs of carriers 3 'arranged between the carriers 3 have drive motors 5 for their driving rollers 4.
  • On the carriers 3 and 3 'lateral guide rollers 6 (see. Fig. 4) are further vertically mounted on both sides unroll the rails 7 (see FIG. 2) in a leading manner.
  • the lifting members 8a and 9a are supported against the supporting floor 10 the rails 7 from.
  • the mechanical lifting motors 8 are driven together via joint spindles 11 (FIGS. 2 and 4).
  • the rails 7 assigned to the castors 4 lie transversely to the rolling line WL of the roller train, not shown, and transversely to these rails 7 there is a pair of rails 7 '.
  • the rails 7 with the transverse rails 7 'rail turntables 12 are arranged which, as shown in FIGS. 6 and 7, are stored in pans 13 and can be rotated here by means of tie rods 14 at an angle C of 45 °.
  • the rail turntables carry a rail section 15 which follows the respective rotation of the rail turntable 12.
  • the device is described as follows: The platform 1 is moved from a position in which the rolling stands, not shown, arranged on it in the rolling line WL (FIG. 5) are located, with the aid of the drive motors 5, with the rollers 4 on the rails 7 rolling out of the rolling line WL in the direction of the rails 7 'after it was previously lowered with the aid of the lifting motors 8 and 9 to such an extent that the castors 4 came to rest on the roller plane of the rails 7 and the guide rollers 6 laterally acted upon the rails and the lifting members 8a and 9a have been brought out of contact with the supporting floor 10. After the running rollers 4 have entered the rail sections 15 of the rail turntables 12 into the position shown in FIG.
  • the rail turntables 12 are rotated with the help of the tie rods 14 together through the angle W (Fig. 6) and with them rotate the carrier 3 or 3 'of the castors 4.
  • the platform 1 can then in one or the other indicated by the double arrow F in Fig. 5 directions of travel on the rails 7 'and a replacement set of roll stands receiving another platform with the aid of the lifting motors 8 and 9 to a lifting height that the roll gap of the respective roll sets on the platform arranged mill stands in the plane of the rolling line.
  • the driving rollers 4 get out of contact with the roller plane of the rails 7, but also the guide rollers 6 which laterally act on the rails 7.
