Ideally this coupling element should be a chain or a screw spindle. | 02-04-2010 |
20100276269 | LEVELING APPARATUS FOR AND METHOD OF FILLING AN OVEN CHAMBER OF A COKE-OVEN BATTERY - The invention relates to a method of filling an oven chamber ( | 11-04-2010 |
20100314234 | METHOD AND DEVICE FOR THE POSITIONING OF OPERATING UNITS OF A COAL FILLING CART AT THE FILLING OPENINGS OF A COKE OVEN - 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. | 12-16-2010 |
20110023860 | MECHANISM FOR THE AUTONOMOUS LATCHING OF COKE OVEN CHAMBER DOORS FOR HORZONTAL COKE OVEN CHAMBERS - A device for latching of horizontal coke oven chambers which is triggered by an auxiliary frame located on the coke oven chamber door is provided. The auxiliary frame is restrictively movable in vertical direction on the coke oven chamber door. During the outward movement, the auxiliary frame hits upwardly against limit stop cams firmly mounted on the oven door and transmitting the vertical traction force onto the coke oven chamber door. During the upward movement, the auxiliary frame actuates levers which are rotationally movable to an axis arranged orthogonally to the coke oven chamber and which are connected to a translatorily freely movable latch. On actuation of this lever, it pulls the latch from the latch take-up bearings mounted on the coke oven chamber door so that the coke oven chamber door is unlatched and opened. In an embodiment of the present invention, the coke oven chamber door can be arrested in the open or closed position with a device suitable for this purpose. | 02-03-2011 |
20110027050 | DEVICE FOR COKE OVEN CHAMBER PUSHING LOW IN HEAT EXCHANGE - A device for pushing the contents of a coke oven chamber includes a pusher ram head with pusher rams mounted there behind, wherein guiding plates or aprons are mounted to a pusher ram head which avoid a simultaneous pressing-in of air into the coke oven chamber, thus preventing a non-desired cooling-off of the coke oven chamber during pushing. The aprons also prevent the pusher ram and the rearward side of the pusher ram head from excessive heat burdens. The aprons can also serve for protecting measuring devices mounted in the enclosure. The aprons can be fabricated from a heat-resistant metallic or ceramic material. The aprons or the pusher ram head can also be provided with a heat-resistant or heat-reflecting coating or with heat-resistant or heat-reflecting tiles. Also shown is a method for pushing of coke oven chambers by applying the inventive device. | 02-03-2011 |

20120216454 | METHOD AND DEVICE FOR THE SUCCESSIVE PRODUCTION OF COAL BRIQUETTES COMPATIBLE WITH A COKE CHAMBER - A method for production of coke chamber-compatible coal briquettes. Horizontally feeding coal into a pressing mould formed from a plate having two parallel terminating walls, which are stationary with respect to the direction of movement of the plate, and a terminating stop wall disposed transversely to the direction of movement of the plate. The side of the pressing mould open to coal is closed by a stationary wall, and the plate is locked in the horizontal direction for the pressing operation. The coal is compacted by a tamping device, having a vertically acting force onto pressing mould to produce a coal briquette. After completion of the coal briquette, the plate is moved horizontally in the longitudinal direction so that the space in the pressing mould becoming free in the horizontal direction is used for producing the next coal briquette. A device for carrying out the method is also disclosed. | 08-30-2012 |
