Mechanism for the autonomous latching of coke oven chamber doors for horizontal coke oven chambers

A device for latching of a coke oven chamber door of horizontal coke oven chambers with external coke oven chamber walls, wherein

• the coke oven chamber door is movably suspended in a vertical direction;
• the coke oven chamber door is mechanically connected by a mechanical traction connection to a device for vertically-directed pulling and relieving;
• and
• the coke oven chamber door is equipped with at least one latch a locking the coke oven chamber in horizontal and vertical direction alongside the external coke oven chamber walls encompassing the coke oven chamber door;
• wherein
• the coke oven chamber door is comprised of an auxiliary frame on the side averted from the coke oven chamber, said auxiliary frame being guided by clamps riding on the coke oven chamber door and being suspended in restricted vertical mobility versus the coke oven chamber door;
• the auxiliary frame is comprised of at least one actuating cam per side on the vertical exterior side;
• a lever is rotationally movable by an axis directed orthogonally to the oven in the direction of running of the actuating cam;
• the latch being translatorily movable alongside the external coke oven chamber wall in outward direction from the coke oven chamber door is connected to the rotationally movable lever and locks the coke oven chamber door against the external coke oven chamber wall by snapping it into a take-up device in the external coke oven chamber wall;
• and
• limit stop cams are mounted on the coke oven chamber door side averted from the oven above the auxiliary frame in the coke oven chamber door, and that the auxiliary frame arrests on said limit stop cams in outward movement after having covered a distinct vertical path.
