FIELD: oil and gas extracting industry. SUBSTANCE: device has carriage with transitional coil and two pressing hydraulic cylinders. On upper flange of transitional coil an assemblage of anti-blowout equipment is mounted. Carriage moves along two guides made in form of I-beams. Guides are rigidly fixed by one ends on well mouth by mounting corbels, and by other ends on screw jacks. Carriage is made with capability of holding on guides by means of corbels with rollers, comprising upper shelf of guides I-beams. Carriage is moved by means of driving hydraulic cylinder. Transitional coil is fixed on coupling rods of pressing hydraulic cylinders by suspension corbels. Transitional coil has lower rotating flange providing for capability of combining its double-arming bolts apertures with bolts apertures of well mouth flange after aligning anti-blowout equipment to well mouth flange. EFFECT: assured water-tightness of flange connection, increased reliability of device operation during performing of anti-blowout equipment alignment to mouth of blower well. 3 dwg |
