Servicing and emptying apparatus for coke-oven battery

A coking installation comprising:

• a longitudinal succession of coking chambers having respective coke sides opening transversely above a bench level above ground level;
• an outer rail extending longitudinally along and adjacent the coke sides of the chambers;
• a quenching-car track extending longitudinally adjacent the coke sides between the outer rail and the chambers;
• a main gangway extending longitudinally at the bench level along the coke sides of the chambers between same and the quenching-car track;
• an inner rail extending longitudinally between the car track and the gangway and immediately adjacent the gangway, the main gangway lying substantially wholly between the inner rail and the coke sides of the chambers;
• a portal support riding on and displaceable along the inner and outer rails above the quenching-car track without substantially overlaying said gangway and carrying
• a door-removing equipment,
• a door-cleaning equipment,
• a doorframe-cleaning equipment, and
• a coke guide;
• means on the portal support for displacing the door-removing equipment and the doorframe-cleaning equipment and guide transversely thereon between an extended position extending horizontally and transversely from the support across the main gangway and engaging one of the coking chambers and a retracted position substantially clear of the main gangway;
• a quenching car displaceable along the car track underneath the portal support to receive coke pushed from the chambers through the guide;
• a gas-collecting hood supported on the support over the quenching car;
• and
• means for aspirating gases released from the coke sides of the chambers between same and the portal support through the hood, the hood being transversely displaceable between the extended and retracted positions also,
• wherein the hood comprises
• a part fixed on the portal support and
• a movable part displaceable relative to the fixed part transversely between the positions,
• wherein the movable hood part and the coke guide are fixed together for a joint transverse displacement, and
• wherein the door-removing equipment and the doorframe-cleaning equipment each include a slide transversely displaceable on the support and a head pivotal on the respective slide about a vertical axis.
