Definitions

the invention relates to a device for mechanically cleaning the side surfaces of the stone plugs of coke oven doors, which taper towards the metallic door body to form vertical gas channels.
a stone plug is understood to mean both the part made of refractory ceramic material and, if present, the stone holder which partially surrounds this ceramic part and is connected to the door body.
the known cleaning devices are designed in such a way that they already reach their working position when approaching the stone plugs, which usually widen towards the door body. the cleaning tools are then already on the surfaces to be cleaned. Recessing areas cannot, of course, be reached by the cleaning tools.
the invention is therefore based on the object of providing a cleaning device which makes it possible to reliably clean all parts of the side surfaces of undercut stone plugs.
the vertical tool columns carrying the cleaning tools move from the driving position, in which the cleaning tools are withdrawn from the side surfaces of the stone plug to be cleaned, to the cleaning position, in which the cleaning tools rest on the side surfaces, are movable.
the shifting can take place by means of one or more drives (hydraulic cylinders or the like).
the invention further proposes that one or more locking devices are provided for the positive locking of tool columns and tool holder frames in the cleaning position.
the stone plug 4 is also fastened to the metallic door body 1, in the present case by means of the stone holder 5.
the invention is equally applicable to stone plugs whose ceramic parts are attached to the door body by means of screws, that is to say without using stone holders.
the stone plug 4 is tapered towards the door body 1, as a result of which a gas channel 6 is formed on both sides.
the cleaning of the side surfaces of the stone plug 4 or the stone holder 5 takes place by means of cleaning tools 7 which are reciprocated in the vertical cleaning direction and which are connected in an articulated manner via pressure bolts 8 and prestressed pressure springs 9 as individual units 10 with tool columns 11. In the working position, these tool columns are arranged to the side of the stone plug.
the number and spacing of the tool units 10 are determined by the length of the surface to be cleaned, i.e. the height of the coke oven door, the cleaning stroke and the required stroke coverage of the tool units.
Both tool columns 11 are connected to the tool holder frame 12, namely horizontally with a plurality of handlebar pairs 13, vertically with linear motors, for example hydraulic cylinders 14. With this arrangement it is achieved that the tool columns 11 relative to the horizontally rigid tool holder frame 12 in the cleaning position (Fig. 1, left Side) and deflected into the driving position (Fig. 1, right side).
tool holder frame 12 and tool columns 11 are mechanically locked to one another by means of a plurality of locking devices 15.
the cleaning forces transmitted from the spring-loaded tool units 1o to the tool columns 11 that can be deflected and deflected are transferred into the horizontally rigid tool holder frame 12.
the tool holder frame is connected to a drive (not shown here) for the cleaning stroke.
the tool columns 11 are in their articulated position (FIG. 1, right side) in the the cleaning tools 7 can move over the wider part of the stone plug 4 of the coke oven door 1.
the limit switch 16 is locked so that the travel movement can only take place in this position.
the tool columns 11 are deflected into the cleaning position (FIG. 1, left side), in which the cleaning tools 7 also rest on the surfaces to be cleaned in the undercut area of the stone plug.
