FIELD: mining.
SUBSTANCE: invention is related to mining industry, in particular to devices, systems and methods for connection of blowout preventer stuffing box to rigging of drilling head or disconnection from it. One or several pin holes arranged with the possibility of reception of one or several cam pins, are located along circumference of adapter parallel to the main hole. One or several pressing holes arranged with the possibility of installation of one or several partially slipping cam clips in them, are displaced relative to pin holes, so that each pin hole partially covers according pressing hole, thus creating a clear space, through which cam clip interacts with cam pin. One or several cam pins are connected to stuffing box of blowout preventer, and one or several partially slipping cam clips, installed in pressing holes of adapter, when required, interact with cam pins for connection of blowout preventer stuffing box to rigging or interaction is stopped for their disconnection, accordingly.
EFFECT: invention provides for liquid medium impermeable insulation of stuffing box from adapter, ensures reliable fixation of blowout preventer stuffing box to pipe without latches, bolts or thread, by means of mutual blocking of necessary number of clips and pins; simplifies operations of stuffing box repair or replacement.
