摘要:
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).

The invention relates to a method of positioning service equipment of a coal-charging larry cart at charging ports of a coke oven, wherein a rail-guided larry cart is moved on the roof of a coke oven and is positioned at locations known by a machine control system and corresponding to charging ports in the oven roof in order to charge the oven chambers, and wherein then at least one piece of service equipment of the coal-charging larry cart is guided to the charging ports by horizontal biaxial positioning movements. According to the invention, an optical measurement method is used after each positioning of the larry cart to detect the coordinates of at least one marking that is applied to the oven roof and that has a fixed relationship with the center axis of a charging port within a measurement field that is predefined by the measurement method and to compare them with reference values that are stored in the machine control system for the marking. The deviations between the measured coordinates and the coordinates stored in the machine control system are determined for both axial directions. Differential values are then taken into account as correction values during the positioning movement of the piece of service equipment. The subject matter of the invention is furthermore formed by an apparatus for carrying out the described method.

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 has a lid lifter with a lift magnet and a jamb cleaner with a cleaning head. Respective travel frames are horizontally movable on rails on the cart in a first horizontal direction, and respective support frames inside the respective travel frames are each movable relative to the respective travel frame in a second horizontal direction transverse to the first direction. Respective carriages horizontally displaceable in the first direction on the support frames carry the support arms for horizontal movement of each of the support arms relative to the respective support frame between an operating position in which the lift magnet or the cleaning head is aligned with a charging hole in the roof of the coke oven and a rest position spaced from the charging hole.

摘要:
An apparatus for charging chambers of a coke oven has a horizontal screw conveyor with a downwardly open outlet and a telescopic charging chute below the outlet having an upper intake funnel and a telescopic lower part alignable with the charging ports by horizontal and longitudinal displacement. A support frame carries the intake funnel and a lifter for vertically displacing the telescopic lower part. A traveling frame in which the support frame moves transversely can also move longitudinally on rails. A seal on a top side of the support frame surrounds the intake funnel of the telescopic charging chute, works together with a horizontal lower flange surface on the outlet of the horizontal screw conveyor, and permits horizontal movement of the intake funnel relative to the outlet of the horizontal screw conveyor.

The invention relates to an apparatus for charging chambers of a coke oven. The basic structure of the apparatus includes a horizontal screw conveyor (1) mounted underneath a coal-charging larry cart, a telescopic charging chute (2) provided below an outlet (3) of the horizontal screw conveyor and having an intake funnel (4) and a telescopic lower part (6) that can be lowered vertically onto charging ports (5) in the top wall of the coke oven, and a lifter (7) for vertically displacing the telescopic lower part (6). The telescopic charging chute (2) is adjustable horizontally in two directions (X, Y) orthogonal to one another relative to the coal-charging larry cart for alignment with the particular position of the charging ports (5). According to the invention, the intake funnel (4) of the telescopic charging chute (2) and the lifter (7) connected to the telescopic lower part are mounted on a support frame (8) that is movable in a straight line inside a traveling frame (9) in a first direction (X). The traveling frame (9) is provided so it is horizontally movable in a second direction (Y) on rails (10) mounted on the lower side of the coal-charging larry cart. A seal (11) is provided on the top side of the support frame (8) that surrounds the intake funnel (4) of the telescopic charging chute (2), that works together with a horizontal flange surface (12) on the surface of the outlet (3) of the horizontal screw conveyor (1), and that permits horizontal adjustment movement of the intake funnel (4) relative to the outlet (3) of the horizontal screw conveyor.

According to the invention, the sealing elements (6) are secured to the reverse side of the tool carrier, which side faces away from the coke oven retort (3). The sealing elements (6) are orientated vertically and completely cover the height of the reverse side. The sealing elements (6) consist of at least one central piece (7) which is immovably fixed to the tool carrier (1) as well as of side wings (8), the side wings (8) being connected with the central piece (7) in such a manner as to be rotationally moveable on vertical axes (9). The side wings (8) are moveable in an adjusting movement in the direction of the coke oven retort (3) against the front surfaces (10) of the anchor stands (2).
摘要:
A strain-free stationary furnace door actuator for a coke furnace battery of the “non-recovery” or “heat-recovery” type, by way of which vertical opening of the coke furnace chamber doors is possible without the use of a coke furnace operating machine, wherein the deviations of the tension elements of the furnace door actuator from the intended arrangements, which result from strain of the transmitting devices, and undesired increases in tension force, which result from differences in the adhesion forces of the coke furnace chamber doors during closure, are avoided by the use of low-strain transmitting devices and tension elements. A method for the strain-free, stationary actuation of the door of a coke furnace battery of the “heat-recovery” type is also disclosed. The method uses rigid tension elements and low-strain transmitting devices for automatically opening and closing coke furnace chamber doors.
