Abstract
The utility model provides a quick-assembling lift sub of a well shutting device, which is composed of clamping plates and a leaflet. The clamping plates are two matched clamping plates, and the middle portion of the clamping plates is circular. When the two clamping plates are matched, the two circular arc forms a standard whole circle. The leaflet is fixed at one end of the two clamping plates, and a bolt type leaflet is arranged at the other end of the two clamping plates. The quick-assembling lift sub of the well shutting device has the advantages of being simple in structure, stable in operation, safe, reliable and suitable for all well drilling systems. The whole process lasts less than 20 minutes, and the efficiency is 3 times higher than the existing efficiency.
Description
Technical field
The utility model relates to a kind of mechanical device, especially a kind of machine tool that is used for oil field blowout preventer installation.
Background technology
The lifting mode of original blowout preventer: marine drilling platform blowout preventer dismounting construction environment is abominable, and labour intensity is big, and degree of danger is high, and the activity duration is long, has caused difficulty to the marine drilling construction.Originally use the wire rope lifting during dismounting blowout preventer; Need 2 length of steel wire rope of each adjustment; And can not keep vertical lifting between blowout preventer and the well head purlin suspension hook, strengthen the damage that the well head purlin is hung, cause the well head purlin to hang use and overhaul or change with regard to needing that gear is hung in the purlin several times.The lifting rule is also violated in the out of plumb lifting, very easily causes security incident.
The utility model content
The purpose of the utility model is to avoid the deficiency of prior art and a kind of fast-assembling blowout preventer elevator of providing.
The technical scheme that the utility model is adopted is: fast-assembling blowout preventer elevator, to form by clamping plate, loose-leaf, and clamping plate are two that cooperatively interact, the centre is a circular arc, two when matching, two circular arc synthetic standards full circle; One end of two clamping plate is that fixedly loose-leaf is fixed, and the other end is equipped with the bolt-type loose-leaf.
Compared with prior art, the utility model has the advantages that: this fast-assembling Elevator structure is simple, smooth operation, safe and reliable, and whole process was less than 20 minutes, and efficient improves 3 times than original, is applicable to all well systems.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Specify the embodiment of the utility model below in conjunction with accompanying drawing.
Fast-assembling blowout preventer elevator is made up of clamping plate 2, loose-leaf 1 and 3, and clamping plate 2 are two of cooperatively interacting, and the centre is a circular arc, and two when matching, two circular arc synthetic standards full circle; One end of two clamping plate 2 is for fixedly loose-leaf 1 is fixing, and the other end is equipped with bolt-type loose-leaf 3.
Hang with the well head purlin during construction elevator is sling, open bolt-type loose-leaf 3, open fast-assembling elevator clamping plate 2, blowout preventer is blocked, after bolt-type loose-leaf 3 places insert latch, can lift blowout preventer.For stability, the reliability that increases lifting, use rigidity clamping plate 2 to replace original wire rope to flexibly connect; Prolonged elevator length in order the well head purlin to be hung vertically lifting by crane; Adopted loose-leaf 1 to be connected in order to accelerate the elevator installation rate with 3; Adopt the D32 steel to make in order to adapt to marine harsh weather elevator critical piece.
