Abstract

A lining machine that includes a base frame, a rail group, a feed apparatus, a lift apparatus and a working platform, the rail group being mechanically fastened to the base frame and the rail group having at least one rail arrangement. The lift apparatus has a roller carriage and a lift unit located on the roller carriage, the roller carriage being provided on the rail arrangement so as to be movable between an installation position and an operating position. The lift unit is connected to the working platform and is designed to lower the working platform into the converter via the converter opening, and the feed apparatus has a roller conveyor, one end of which ends at the lift apparatus.

First claim

1 . A transport apparatus for a lining machine,
wherein the transport apparatus has a first transport space and a first roller table arranged below the first transport space for transporting a first item to be transported, wherein the first roller table comprises a first roller frame, and a first roller arrangement with at least two first rollers, wherein the first roller table has a second roller frame and a second roller arrangement with at least one second roller, wherein the second roller frame is arranged in the first roller frame so as to be movable along an axis between a first position and a second position different from the first position, wherein each of the first rollers is attached to the first roller frame so as to be rotatable about a first axis of rotation which is inclined with respect to the axis, wherein the second roller is arranged between the two first rollers, wherein the second roller is mounted on the second roller frame so as to be rotatable about a second axis of rotation, which is inclined with respect to the axis and aligned with the first axis of rotation, wherein the first roller has a first rolling surface on the circumferential side and the second roller has a second rolling surface on the circumferential side, wherein, in the first position of the second roller frame, the second roller is arranged recessed between two first rollers and the first rolling surface projects beyond the second rolling surface in the direction of the axis, wherein in the second position the second roller frame is raised relative to the first position and the second rolling surface projects beyond the first rolling surface in the direction of the axis.

2 . The transport apparatus as claimed in claim 1 ,
having a first removal table and a second removal table offset in the circumferential direction relative to the axis, wherein the first removal table has a third roller arrangement with at least one third roller and a third roller frame, wherein the third roller is attached to the third roller frame so as to be rotatable about a third axis of rotation, wherein the second removal table has a fourth roller arrangement with at least one fourth roller and a fourth roller frame, wherein the fourth roller is attached to the fourth roller frame so as to be rotatable about a fourth axis of rotation, wherein the third axis of rotation is aligned parallel to the first axis of rotation and the fourth axis of rotation is aligned parallel to the second axis of rotation.

3 . The transport apparatus as claimed in claim 2 ,
having a housing with a closable first housing opening and a closable second housing opening which is arranged offset to the first housing opening in the circumferential direction relative to the axis-, wherein the housing encloses the first transport space at least in portions, wherein the first housing opening is arranged between the first removal table and the first transport chamber and the second housing opening is arranged between the second removal table and the first transport chamber.

4 . The transport apparatus as claimed in claim 1 ,
having a second transport space and a second roller table, wherein the second roller table is arranged offset along the axis relative to the first roller table and closes off the first transport space at the top and delimits the second transport space at the bottom, wherein the second roller table has a fifth roller frame and a fifth roller arrangement with at least one fifth roller, wherein the fifth roller is attached to the fifth roller frame so as to be rotatable about a fifth axis of rotation, wherein the fifth axis of rotation is arranged parallel to the first axis of rotation.

5 . The transport apparatus as claimed in claim 4 ,
wherein the first removal table has a lifting unit, wherein the lifting unit is connected to the third roller frame and is designed to move the third roller frame between a first removal position and a second removal position different from the first removal position, wherein, in the first removal position, the first roller arrangement and the third roller arrangement are arranged substantially at the same height, wherein, in the second removal position, the fifth roller arrangement and the third roller arrangement are arranged substantially at the same height.

6 . The transport apparatus as claimed in claim 1 ,
wherein the first roller table has an unloading opening, wherein the first transport space is accessible from below through the removal opening and the first item to be transported can be unloaded through the removal opening, wherein at least the first roller arrangement and the second roller arrangement are arranged laterally of the removal opening.

7 . A lining machine for renewing a lining of a converter through a converter opening,
wherein the lining machine comprises a base frame, a rail group, a feed apparatus, an elevator apparatus and a working platform, wherein the rail group is mechanically attached to the base frame, wherein the rail group has at least one rail arrangement, wherein the elevator apparatus comprises a roller carriage and an elevator unit arranged on the roller carriage, wherein the roller carriage is arranged on the rail arrangement so as to be movable between an installation position and an operating position, wherein the elevator unit is connected to the working platform and is designed to lower the working platform into the converter via the converter opening, wherein the feed apparatus has a roller conveyor which ends on one side at the elevator apparatus.

8 . The lining machine as claimed in claim 7 ,
comprising a transport apparatus, wherein the transport apparatus has a first transport space and a first roller table arranged below the first transport space for transporting a first item to be transported, wherein the first roller table comprises a first roller frame, and a first roller arrangement with at least two first rollers, wherein the first roller table has a second roller frame and a second roller arrangement with at least one second roller, wherein the second roller frame is arranged in the first roller frame so as to be movable along an axis between a first position and a second position different from the first position, wherein each of the first rollers is attached to the first roller frame so as to be rotatable about a first axis of rotation which is inclined with respect to the axis, wherein the second roller is arranged between the two first rollers, wherein the second roller is mounted on the second roller frame so as to be rotatable about a second axis of rotation, which is inclined with respect to the axis and aligned with the first axis or rotation, wherein the first roller has a first rolling surface on the circumferential side and the second roller has a second rolling surface on the circumferential side, wherein, in the first position of the second roller frame, the second roller is arranged recessed between two first rollers and the first rolling surface projects beyond the second rolling surface in the direction of the axis, wherein the second position the second roller frame is raised relative to the first position and the second rolling surface projects beyond the first rolling surface in the direction of the axis, wherein the transport apparatus has a further elevator unit, wherein the further elevator unit 59 is connected to the first roller table and is configured to move the first roller table between the first position and the second position.

9 . The lining machine as claimed in claim 8 ,
wherein the further elevator unit has a second winch, wherein the second winch is mechanically connected to the firs
