Strain-free stationary furnace door actuator for a coke furnace battery of the "heat-recovery" type

A coke oven plant having an expansion-free stationary oven door controller for a coke oven plant type “Heat-Recovery”, comprising

• a coke oven bench or a coke oven battery with a quantity of in-line coke oven chambers,
• coke oven chamber doors, which are vertically movable and close the coke oven chambers at the front,
• a horizontally displaceable tension member, which runs along the front of the coke oven chamber at least in parts, and which is equipped with a drive unit, and which is equipped with at least one draw hook,
• a fraction trolley, which runs on a guiding device along the front of the coke oven chamber at least in parts in a horizontally movable manner,
• a transmission device, which is firmly connected to the traction trolley, and which is firmly connected to the coke oven chamber doors via deflection pulleys, and which is to be at least temporarily connected to the rigid tension member via the traction trolley,
• wherein the tension member is rigid and expansion-free, and
• the transmission device is low in expansion, and
• a connecting mechanism connects the traction trolley to the rigid tension member upon request.

A method for the expansion-free, stationary oven door control of a coke oven plant type “Heat-Recovery”, in which

• the coke oven chamber doors of a coke oven bench or a coke oven battery with a quantity of in-line coke oven chambers are to be periodically opened and closed, and
• a traction trolley which is equipped with a connecting mechanism and is movable along the front of the coke oven chamber via a guiding device remains in the resting position without request,
• wherein a rigid and expansion-free tension member, which is equipped with a draw hook, moves upon request longitudinally along the front of the coke oven chamber, and
• the connecting mechanism connects the traction trolley and the tension member upon request via the draw hook, such that the traction trolley with the tension member is moved longitudinally along the front of the coke oven chamber, and
• the traction trolley opens the coke oven chamber door via a low-expansion transmission device and closes the coke oven chamber door upon the return of the traction trolley.
