Patent ID: 8333238

Claim:
A snubbing apparatus for moving well tubing through a blowout preventer, comprising: a support frame having an upper end and a lower end, the lower end being connectable to the blowout preventer; at least one standing tubular engaging assembly connected to the support frame, the standing tubular engaging assembly being operable between a tubular engaging condition and a tubular release condition; at least two linear actuators, each actuator having a cylinder and a rod, the cylinder having an upper end and a lower end, and the rod having a proximal end and a distal end, the rod extending from the upper end of the cylinder and being operable between a retracted condition and an extended condition, the cylinders connected to the support frame in a diametrically opposing relationship to one another and with the lower ends of the cylinders extending downwardly beyond the lower end of the support frame and spaced apart from one another a distance sufficient so that the lower ends of the cylinders are positioned on opposing sides of the blowout preventer when the support frame is connected to the blowout preventer; and a traveling tubular engaging assembly connected to the distal end of the rods, the traveling tubular engaging assembly being operable between a tubular engaging condition and a tubular release condition, wherein the support frame further comprises a slip frame including a bottom plate, a top plate, and at least two side plates, the bottom plate and the top plate each having an opening axially aligned with the other opening to receive the well tubing therethrough, the bottom plate defining the lower end of the support frame, the standing tubular engaging assembly being connected to at least one of the bottom plate and the top plate and about the opening of the respective top and bottom plate.
