Abstract

Metoder og apparatur for etablering og bryting av rørforbindelser i en rørstreng vises. I visse aspekter inkluderer en tangsammenstilling lukeforsynt krafttang og sikringstang koplet til en dreiemomentstang. Kjevene på tengene kan være arrangert rundt omkretsen ved hjelp av støtteelementer anordnet mellom tilstøtende kjever for i vesentlig grad å fullstendiggjøre en 360( lukket sirkel. En hydraulisk krets kan likt fordele fluid og trykk for å aktivere kjevene. Krafttangen kan inkludere en lukeforsynt motor drevet av minst tre drivmotorer. Rotoren kan selektivt fysisk låses mot rotasjon eller bevegelse av én eller flere rotorlåser. Videre kan tangsammenstillingen inkludere en gjensidig blokkering som hindrer aktivering av drivmotorene inntil rotorlåsene aktiveres for å frigi rotoren. I tillegg kan lukelåser sikre tengene og rotoren når de er lukket og et frigivelsesbart koplingsarrangement kan fremme inngrep av en motor til en rotorpumpe.Methods and apparatus for establishing and breaking pipe connections in a pipe string are shown. In some aspects, a forceps assembly includes hatch-mounted power pliers and fuse bars coupled to a torque bar. The jaws of the joints may be arranged around the circumference by means of support members arranged between adjacent jaws to substantially complete a 360 (closed circle. A hydraulic circuit may equally distribute fluid and pressure to activate the jaws. The clamp may include a hatched motor driven by The rotor can be selectively physically locked against rotation or movement of one or more rotor locks, and the pliers assembly may include a reciprocal lock which prevents actuation of the drive motors until the rotor locks are activated to release the rotor. closed and a releasable coupling arrangement can promote engagement of a motor to a rotor pump.
