Definitions

  • the invention relates to a device for handling and / or transporting work rolls and / or back-up rolls of a roll stand, with which the work rolls and / or the back-up rolls can be moved from the rolling stand to a roll workshop by means of a locomotive movable on a road surface.
  • Devices of this type are used to allow a change of the rolls of a rolling mill, when the rollers have reached their service life and must be spent for reworking in a roller workshop. The removed rolls are then replaced with a new set of rolls so that production can continue.
  • the EP 1 954 416 B1 shows such a device, in which it is provided that a support structure for receiving the rollers has a change carriage, wherein the support structure on its upper side rails, on which the change carriage rests and is movable transversely to a roll change pit, wherein the change carriage is formed with devices for receiving the roller sets.
  • Similar solutions are described in EP 1 951 452 B1, in WO 2005/089972 A1, in WO 2007/080091 A1, in EP 1 951 453 B1, in WO 03/015949 A1 and in DE 31 23 933 C2 described.
  • DE 15 27 628 A1 discloses a roll changing device, which is characterized in that a roll tentering stand has two superimposed one another
  • the present invention is based on the invention to further improve a generic device to the effect that a simpler design is present and components of only low complexity are needed.
  • the solution to this problem by the invention is characterized in that at least two lanes arranged at different height levels are arranged, on which a roller can be moved by means of the locomotive, and that a lifting table is provided, which is intended and suitable, the locomotive to raise or lower on one of the at least two different height levels to spend on the respective roadway.
  • a height level of the roadway is preferably arranged so that at least one work roll can be moved out of the rolling mill stand.
  • Another one Height level of the roadway is preferably arranged so that at least one support roller can be moved out of the rolling stand.
  • the lift table can be arranged at the end of the lanes. Alternatively, however, it may also be arranged in the area of the roadways.
  • At least one of the lanes may adjoin or intersect a transverse shift table.
  • the transverse sliding table can be arranged between the lifting table and the rolling stand. But it is also possible that the lifting table is arranged between the rolling stand and the transverse displacement table.
  • Each of the lanes may be provided with rails on which the locomotive is movable.
  • the rolls or sets of rolls to be transported slide directly onto the travel rails.
  • a roll changing chair can be arranged.
  • the length of the lifting table is - seen in the direction of travel of the locomotive - preferably the same length or only slightly longer than the length of the locomotive. This allows a short construction.
  • the lift table can be raised and lowered to a desired height with lifting and lowering means so that the locomotive can easily travel from the lift table to the roadway and back.
  • the lift table can be raised and lowered with at least one hydraulic piston-cylinder system.
  • the proposed invention is preferably used in quarto frameworks, but is not limited thereto.

  • a lower work roll 2 and an upper work roll 3 are arranged and a lower support roller 4 and an upper support roller 5.
  • the end of life of a roller 2, 3, 4, 5 reached this is removed from the rolling stand 6 and for reworking , z. B. for regrinding, spent in the roller workshop 10.
  • the device serves 1.
  • a locomotive 9 For transporting the rollers 2, 3, 4, 5 of the rolling hall 14 in the roller workshop 10 and vice versa a locomotive 9 is used. This can on a roadway 7, 8 pull the roller or sets of rollers directly on the travel rails or push.
  • the direction of movement of the locomotive 9 is marked in Figures 1 and 2 with the double arrow 15. More specifically, in the present case there are two lanes 7 and 8, which are arranged at different height levels hi and h 2 in the direction of the vertical V.
  • the first height level hi of the roadway 7 is chosen such that it is suitable for pulling a work roll 2 or both work rolls 2, 3 out of the weighing stand 6 or for pushing these rolls into the rolling stand 6.
  • the second height level h 2 of the lane 8 is lower and is aligned to pull a support roller 4 out of the rolling stand 6 or to push it into the rolling stand 6.
  • the invention provides that a lifting table 11 is present. This is designed so that it can lift or lower the locomotive 9 to one of the two height levels hi and h 2 , so as to spend the locomotive 9 on the respective lane 7 and 8 respectively.
  • the lifting movement of the lifting table 11 is marked in Fig. 1 with the double arrow 16.
  • To secure the lifting table locks 18 are provided in the lower shaft area.
  • a transverse displacement table 12 is also provided. With this, a transverse displacement can take place, in the direction of the double arrow 17 in Fig. 2.
  • a transverse displacement can take place, in the direction of the double arrow 17 in Fig. 2.
  • EP 1 951 453 B1 of the applicant detailed information so that reference is made to this document.
  • a single locomotive 9 can be used to handle all rolls 2, 3, 4, 5 of the roll stand 6 or to transport. Nevertheless, the locomotive 9 can always be used optimally and without special coupling devices, so that their use is structurally simple.
  • the locomotive 9 is relatively powerful. As can be seen in Fig. 5b, a pair of work rolls 2, 3 are moved directly on the travel rails. As can be seen in Fig. 5c, the locomotive 9 is able to move the two support rollers 4, 5 on a roll changing chair 13 (in Fig. 5c, the upper lane 7 is not shown).
  • the second concrete embodiment according to FIGS. 6a to 6d is designed similarly to the first exemplary embodiment (FIGS. 4 and 5).
  • the transverse sliding table 12 is arranged in the region of the roadways 7, 8; the plan view of the second embodiment corresponds to that of the first embodiment (see Fig. 4).
  • the locomotive 9 is here only schisse- rather executed.
  • FIGS. 7 and 8 are based on the second exemplary embodiment, that is to say a relatively weak locomotive 9 is used. Accordingly, the support rollers 4, 5 are also moved separately here (see Fig. 8c and 8d).
  • the difference from the previous exemplary embodiments lies in the fact that the lifting table 11 is no longer arranged at the end of the travel, but in the area of the carriageways 7, 8. the lanes 7, 8 continue beyond the lifting table 11 in the area remote from the rolling mill 6 area.
  • transverse displacement table 12 could also be arranged here between the lifting table 11 and the rolling stand 6, in the exemplary embodiment according to FIGS. 7 and 8 it is provided that the transverse displacement table 12 beyond the lifting table 11 is located in the region of the driving distance from the rolling stand 6. tracks 7, 8 is provided. Incidentally, the transverse displacement table 12 is made smaller here than in the cases of FIGS. 4 to 6.
  • Typical travel speeds of the change cars pulled by the locomotive 9 are approximately 200 to 400 mm / s when loaded with the work rolls and of the same order of magnitude when loaded with a single back-up roll. When loading with two back-up rolls, a value between 50 and 100 mm / s is typical.
