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, 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 with devices for receiving the roller sets is formed.
- the DE 15 27 628 A1 discloses a roll changing apparatus which is characterized in that a roll tenter has two superposed platforms each of which can receive a pair of work rolls this framework is vertically displaceable, so that each of the two platforms for transferring the work rolls between the platform and the rolling mill and between the platform and a roller storage space can be arranged at a corresponding height.
- a replacement set of rollers can be kept near the rolling mill until he is switched.
- the disadvantage here is the relatively complex construction of the device.
- the present invention has for its object to further improve a generic device to the effect that a simpler design is present and components of low complexity are needed.
- the solution of this object by the invention is characterized in that at least two arranged at different height levels lanes 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 on a to raise or lower 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 displacement 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 rolling hall 14 is indicated in the right area, in which a rolling stand 6 is arranged.
- a roller workshop 10 In the left area of the figures is a roller workshop 10. The two areas are separated by a wall, not shown.
- 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. Is 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 1 serves for this purpose.
- a locomotive 9 is used to transport the rollers 2, 3, 4, 5 from the rolling hall 14 in the roller workshop 10 and vice versa.
- 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, there are present two lanes 7 and 8, which are arranged at different height levels h 1 and h 2 in the direction of the vertical V.
- the first height level h 1 of the roadway 7 is selected so that it is suitable to pull a work roll 2 or both work rolls 2, 3 out of the roll stand 6 or to push 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 such that it is, the engine 9 on one of the two height levels 1 and h 2 can raise or lower in order to spend the locomotive 9 on the respective roadway 7 and 8 respectively.
- the lifting movement of the lifting table 11 is in Fig. 1 marked 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 provided. With this, a transverse displacement can take place, in the direction of the double arrow 17 in Fig. 2 ,
- the technology of lateral displacement can be found in the EP 1 951 453 B1 the notifying party so that reference is made to this document.
- FIGS. 4 to 8 are shown a total of three different concrete embodiments of the invention. All three embodiments work in principle according to the concept of the invention, ie there are (at least) two at different height levels h 1 , h 2 arranged lanes 7, 8 available, on which a roller 2, 3, 4, 5 can be moved by means of the locomotive 9, further comprising a lifting table 11 which is intended and adapted to raise or lower the locomotive 9 to one of the at least two different height levels h 1 , h 2 in order to pass it onto the respective lane 7, 8.
- the transverse displacement table 12 in the region of the lanes 7, 8 arranged, ie the transverse displacement table crosses the lanes 7, 8.
- the lifting table 11 is located at the end of the lanes 7, 8.
- the locomotive 9 is relatively powerful. As in Fig. 5b can be seen, a pair of work rolls 2, 3 is moved directly on the Verfahrschienen. As in Fig. 5c can be seen, 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 the FIGS. 6a to 6d is similar to the first embodiment ( Fig. 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 (s. Fig. 4 ).
- the locomotive 9 is executed here only weaker. Accordingly, it is still possible to move the two work rolls 2, 3 as a pair (s. Fig. 6b ). However, the support rollers 4, 5 must be moved separately from the locomotive 9, as in the FIGS. 6c and 6d is shown.
- the third specific embodiment according to the FIGS. 7 and 8th leans on the second embodiment, ie it is a relatively weak locomotive 9 is used. Accordingly, the support rollers 4, 5 are also moved separately here (s. Fig. 8c and 8d ).
- the difference from the previous embodiments is that the lifting table 11 is no longer located at the end of the track, but in the area of the lanes 7, 8. D. h. the lanes 7, 8 continue beyond the lifting table 11 in the area remote from the rolling mill 6 area.
- the transverse displacement table 12 could also be arranged between the lifting table 11 and the roll stand 6, in the exemplary embodiment according to FIG Fig.
- the transverse shift table 12 is made smaller here than in the cases of FIGS 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.
