Abstract

A carrying device ( 1 ) for the frontal removal of a roll body from a roll frame, comprising a main frame ( 2 ) and a receiving section ( 3 ) for the roll body. The receiving section ( 3 ) can be transferred from an introduction position (E) into a supporting position (S). The receiving section ( 3 ) has a profile which at least partially encloses the roll body in the supporting position (S), and the carrying device ( 1 ) can be pushed in below the roll body with the receiving section ( 3 ) in the introduction position (E), and the roll body is carried with the receiving section ( 3 ) in the supporting position (S).

First claim

1 - 15 . (canceled)

16 . A carrying device for frontal removal of a roll body from a roll mill, the carrying device comprising:
a main frame, and a receiving section for the roll body, which can be transferred from an introduction position into a supporting position, wherein the receiving section has a profile which at least partly encloses the roll body in the supporting position, and the carrying device can be pushed in below the roll body with the receiving section in the introduction position and the roll body is carried with the receiving section in the supporting position.

17 . The carrying device according to claim 16 , wherein the main frame has a substantially L-shaped form with two legs standing at an angle to each other, and the receiving section is pivot-mounted in an end region of one leg.

18 . The carrying device according to claim 17 , wherein one leg has guiding means.

19 . The carrying device according to claim 16 , wherein the receiving section can move, by actuating means, between the introduction position and the supporting position.

20 . The carrying device according to claim 19 , wherein the actuating means comprises a threaded rod.

21 . The carrying device according to claim 20 , wherein the threaded rod is mounted in a threaded bushing, and the threaded bushing is mounted in a same leg of a substantially L-shaped main frame with two legs standing at an angle to each other as the receiving section.

22 . The carrying device according to claim 21 , wherein the threaded rod is connected at one end to an expanding joint in a way that is rotatable, yet firm against pushing and pulling, the expanding joint is expandable by rotating of the threaded rod, and the receiving section can be transferred from the introduction position into the supporting position.

23 . The carrying device according to claim 22 , wherein the receiving section can be transferred from the introduction position into the supporting position by increasing a distance between the threaded bushing and the end of the threaded rod which is connected to the expanding joint.

24 . The carrying device according to claim 20 , wherein the threaded rod is outfitted with means for accommodating a drive unit.

25 . The carrying device according to claim 16 , wherein means for limiting the movement of the receiving section are provided.

26 . A roll mill with a plurality of rolls,
wherein at least one roll comprises a roll body with two rolling stubs, the roll body is releasable by moving apart the two rolling stubs from each other, beneath the at least one roll guiding means for a roll carrying device are arranged or can be arranged beneath the roll such that the roll body can be removed frontally and the roll carrying device is movable in a direction perpendicular to the roll axis.

27 . The roll mill according to claim 26 , wherein the guiding means enables a guiding of the roll carrying device perpendicular to a plumb-line.

28 . The roll mill according to claim 26 , wherein the guiding means comprise at least one guide rail.

29 . The roll mill according to claim 26 , wherein the guiding means are arranged or can be arranged in a product space.

30 . A method for frontal removal of a roll body from a roll mill with a plurality of rolls, wherein at least one roll comprises a roll body with two rolling stubs and the roll body is releasable by moving apart the two rolling stubs from each other, the method comprising:
introducing at least one roll carrying device with a receiving section for the roll body underneath the roll, wherein the at least one roll carrying device is resting on a frame of the roll mill; lifting of the receiving section of the at least one roll carrying device such that the roll body is in an operative connection with the roll carrying device; releasing of the roll body by moving apart the two rolling stubs, so that the roll body is resting on the at least one roll carrying device; and moving the at least one roll carrying device perpendicularly to the roll axis.
