Apparatus on a coal-charging larry cart for lifting a lid out of a charging hole in the roof of a coke oven and for cleaning the charging-hold jamb

Abstract

The invention relates to an apparatus on a coal-charging larry cart for lifting lids out of charging holes in the roof of a coke oven and for cleaning the charging-hole jambs. The basic construction of this apparatus includes a lid lifter (3) having a support arm (4) carrying a lift magnet (5), a jamb cleaner (6) having a support arm (4′) carrying a cleaning head (7), drives (8, 8′) for vertically positioning the support arms (4, 4′). The lid lifter (3) and the jamb cleaner (6) are each mounted on a respective carriage (12, 12′) for horizontal movement between an operating position (A) in which the lift magnet (5) or the cleaning head (7) is aligned with a charging hole (13) in the roof of the coke oven, and a rest position (B) spaced from the charging hole. According to the invention the carriage (12, 12′) has a travel frame (15) horizontally movable on rails (14) on the underside of the coal-charging larry cart along a first axis and a support frame (16) inside the travel frame (15), the support frame (16) being guided for movement relative to the travel frame along a second axis transverse to the travel direction of the travel frame (15), the drive (8, 8′) for the cover lifter (13) and/or the jamb cleaner (6) being mounted on the support frame (16).
