Coke drum automated drill stem guide and cover system

A drill stem guide assembly for insertion of a drill stem into a coke drum for coke cutting operation, comprising:

• a first cover, moveable between an open position and a folded closed position, comprising:
• a first guide section
• a second cover comprising:
• a second guide section;
• a mounting frame configured to pivotally attach each of the first cover and the second cover to the coke drum;
• and
• an actuator mounted with the mounting frame to move the first cover between the open position and the folded closed position,
• wherein the first guide section and the second guide section form a passageway for guiding the drill stem as the drill stem is moved within the coke drum.

A drill stem guide assembly for insertion of a drill stem into a coke drum for coke cutting operations, comprising:

• a plurality of covers moveable by folding the covers between an open position and a folded closed position, each of the plurality of covers comprising:
• a guide section;
• and
• a plurality of actuators configured to communicate with the plurality of covers so as to move the plurality of covers between the open position and the folded closed position,
• wherein, when the plurality of covers is in the folded closed position, the guide sections of the plurality of covers form a passageway for guiding the drill stem as the drill stem is moved within the coke drum.

• a control system configured to communicate with the plurality of actuators,
• a limit switch disposed on at least one of the plurality of covers, the control system being configured to communicate with the limit switch,
• wherein the limit switch is configured to signal the control system to shutdown a high pressure water supply of a cutting tool when the limit switch is triggered,
• wherein the limit switch is triggered when the plurality of covers is not in the closed position.

A coke cutting system comprising:

• a plurality of covers moveable by folding the covers between an open position and a folded closed position, each of the plurality of covers comprising:
• a guide section;
• a mounting frame mounted above the top head of a coke drum configured to pivotally attach the plurality of covers;
• a plurality of actuators disposed on the mounting frame to move the plurality of covers between an open position and a folded closed position,
• wherein, when the plurality of covers is in the folded closed position, the guide sections of the plurality of covers form a passageway for guiding the drill stem as the drill stem is moved within the coke drum to cut the coke and allow free flow of loose coke out of the bottom of the coke drum;
• a drill stem adapted for raising and lowering into and out of the coke drum, comprising:
• a rotatable nozzle disposed on a end of the drill stem;
• a rotation motor attached to the drill stem for rotating the rotatable nozzle;
• a winch motor for raising and lowering the drill stem;
• and
• a high pressure water supply in fluid communication with the drill stem.
