Coke oven operating machines and method for operating a coking oven by means of such Koksofenbedienungsmaschinen each of the aforementioned Species have been known in practice for decades. In the known method are following the coking process, the oven doors of the respective Coking chamber opened by means of a door lever device. The door lever device has a door lift, on the corresponding means (hook) for Intervene in corresponding pocket-like openings on the doors serve. The Openings have a certain predetermined game, so that even at a non-centric attachment of the door lifter engage the hooks in the openings can and the oven door can be removed. After opening the doors At the discharge side of the furnace, a coke cake guide of a coke cake guide device is formed scheduled to be located in front of the chambers usually Master gear to bridge, so that the expressed coke, for example, in a Coke fire truck falls. The expression of the coke from the respective coking chamber takes place via a Koksausdrückeinrichtung with a stamp-like design Printhead.

After expressing the coke from the respective coking chamber, it is necessary the sealing surfaces on the oven doors and on the frame of the respective coking chamber to clean, since during the coking process deposits and others Impurities arise that settle on the aforementioned sealing surfaces. These deposits can affect the gas-tight seal of the coking and therefore have to be removed. To clean the frame of the Coking chamber serves a frame cleaning device with a frame cleaner, which is used for cleaning the frame to this or. simultaneously The removed oven door is for cleaning purposes of a door cleaning device supplied on the Koksofenbedienungsmaschine. After completion of the Cleaning operations, the door is again in the frame to close the coking used.

Coke ovens of the aforementioned type consist of a variety of disc-like trained coking chambers arranged side by side in a long row are, with the battery axis transverse to the direction of the individual coking horizontal chamber longitudinal or furnace axes runs. Ideally the individual coking chambers are each arranged vertically to the battery axis, d. H. passing through the horizontal longitudinal axis of the coking chamber vertical plane is from the battery axis under a substantially rectangular Angle cut.

However, it can happen that coking chambers deviate from the through the horizontal longitudinal axis of the coking chamber extending vertical plane are aligned. This misalignment or inclination of the coking chambers compared to the vertical, which has been known for decades, is when the door is lifted and in the frame cleaning compensated by the fact that the vertically aligned Door lifter and also the vertically aligned frame cleaner on a corresponding drive in the pocket-like openings or the frame pressed to lift the door or clean the frame.
