A mechanism for purifying coke furnaces doors contains vertical guide, at least one carriage movably disposed on said guide, disposed on carriage holders actuators for purifying vertical section of sealing frame and actuators for purifying gas flues and lateral surfaces of the door, movably disposed in horizontal guides of carriage with actuators for purifying horizontal sections of doors, and drive for the back and forth movement of carriage and bogie, which comprises mounted above and below vertical guide respectively drive and driven shafts,on which star gears pull chain is disposed connected to the carriage. The mechanism is provided in addition with catchers interacting with horizontal sections of doors body, which are hingedly fixed above and below vertical guide and connected between them by rod, at that the upper catcher is made spring-loaded in vertical, and horizontal guides of bogies are mounted on respective catchers, at that bogies by means of cranks are kinematically connected respectively to drive and driven shafts of the drive, and holders of actuators for purifying vertical sections of sealing frame are made of U-like shape and flexibly and movably horizontally fixed on the carriage. At that on every flange of holders disposed against lateral surfaces of doors there are disposed actuator for purifying vertical sections of sealing frame, which is fixed on flange edge, and actuators for purifying gas flues and lateral surfaces of doors, which are mounted on lever spring-loaded horizontally hingedly fixed on the holder flange.
