In the grappling inner sleeve 2.
Specifically, major axis 1 is substantially shaft-like in cylinder, and its upper end is connected with joint 11, and the joint 11 is carried for screwed connection
Rise the box cupling of pipe nipple；The lower end screwed connection of major axis 1 has grappling slip spider 4, and the grappling slip spider 4 is used for screwed connection sucker rod
Post.In the present embodiment, along the circumferential direction uniformly offer on grappling slip spider 4 it is multiple arrange at equal intervals radially slide groove
42, this radially slides in groove 42 and is movably disposed within grappling pawl 41, that is, grappling pawl 41 can be being radially slided in groove 42 relatively
The radial displacement of major axis 1, the outside of multiple grappling pawls 41 is arranged with multiple split circlips 411, and the split circlip 411 is used for
The multiple grappling pawls 41 of flexible fastening in circumference.
Grappling inner sleeve 2 is substantially in cylindrical tube shape, and it is set in the outside of major axis 1, and the lower end for anchoring inner sleeve 2 has been welded to connect
Insertion section 21, the insertion section 21 is set on major axis 1 and is threaded on the lower end outer wall of major axis 1, connects on grappling slip spider 4
The multiple grappling pawls 41 for connecing are located at the outside of insertion section 21.In the present embodiment, the upper end of grappling inner sleeve 2 is fixedly connected with grappling
Handle 23, the grappling handle 23 can drive the relative major axis 1 of grappling inner sleeve 2 to carry out axial rotation, in insertion section 21 and the spiral shell of major axis 1
Under line coordinates, insertion section 21 drives the relative axial displacement of major axis 1 of grappling inner sleeve 2, specifically, in the upper end of grappling handle 23 with
End is respectively equipped with the locking nut 231 and locking nut 232 being connected in grappling inner sleeve 2, and grappling handle 23 is in shaft-like, its middle part
With screwed hole, grappling handle 23 is threaded in grappling inner sleeve 2 by its screwed hole, and screw thread company is gone back on grappling handle 23
Fixing nut 233 is connected to, the fixing nut 233 is located between locking nut 231 and locking nut 232.Locking nut 231, lock
Being provided for of tight nut 232 and fixing nut 233 is positioned at grappling handle 23 in grappling inner sleeve 2, so that operating personnel turn
During dynamic grappling handle 23, grappling handle 23 is rotated together with grappling inner sleeve 2.
Anti- spray boom 3 is in substantially cylindrical tube shape, and it is axially displaceably set in the outside of grappling inner sleeve 2, in grappling inner sleeve 2
Lower end be connected with outer jump ring 22, sealing rubber cover 31 is folded between anti-spray boom 3 and outer jump ring 22；In the present embodiment,
The threaded upper ends of grappling inner sleeve 2 are connected with blowout prevention handle 24, specifically, press from both sides between the blowout prevention handle 24 and the upper end of anti-spray boom 3
The steel ball seat 33 being set in grappling inner sleeve 2 is provided with, steel ball seat 33 is provided with steel ball 331, and steel ball 331 connects with blowout prevention handle 24
Touch, by rotating spray-proof handle 24, so that the Relative anchor inner sleeve 2 of blowout prevention handle 24 is moved axially, so as in blowout prevention handle 24
3 Relative anchor inner sleeve of anti-spray boom 2 is set axially to move down under effect, in the presence of anti-spray boom 3 with outer jump ring 22, sealing rubber cover 31
It is extruded so as to radial outward expansion.Further, the lower end of grappling inner sleeve 2 is also arranged and is connected with sealing cup 32, the sealing
Leather cup 32 is located at the lower end of outer jump ring 22, and the external diameter of the sealing cup 32 is more than the internal diameter of oil pipe.
The principle that the blowout prevention of the hand well blowout preventing device and oil draining function are realized is：By rotating spray-proof handle 24, make
Blowout prevention handle 24 promotes anti-spray boom 3 to move down, and so as to promote sealing rubber cover 31 to produce elastic deformation, makes sealing rubber cover 31 radially
Outwards expansion reaches the purpose of sealing oil pipe inner space, namely the blowout prevention function of realizing the hand well blowout preventing device；Connection
The external diameter of the sealing cup 32 in grappling inner sleeve 2 due to more than oil pipe internal diameter, therefore, it matches somebody with somebody with tube inner wall for interference
Close, play the effect of auxiliary seal.In draining, opposite direction rotating spray-proof handle 24, anti-spray boom 3 is no longer by blowout prevention handle 24
Compress, anti-spray boom 3 is moved up, sealing rubber cover 31 is restored no longer to be formed with tube inner wall and sealed.
The principle of the grappling of the hand well blowout preventing device is：Drive grappling inner sleeve 2 synchronous by rotating grappling handle 23
Rotation, in the present embodiment, the inner side of grappling pawl 41 has insertion inclined-plane, and the outside of insertion section 21 has male cone (strobilus masculinus), the outer cone
Face is engaged with insertion inclined-plane.Because the outside of insertion section 21 is formed as turbination shape, it is inserted with multiple grappling pawls 41
In the state of entering inclined-plane cooperation, as insertion section 21 constantly moves down, the radial direction of insertion section 21 pushes against multiple grappling pawls 41, makes grappling
The Relative anchor inner sleeve 2 of pawl 41 is moved outwards, and tightly Figure enters in oil pipe the card tooth for being moved outwards and making on the outside of it when grappling pawl 41
During wall, the grappling function of the hand well blowout preventing device is realized.When opposite direction rotates grappling handle 23, the card tooth of grappling pawl 41
Bounce back in the case where split circlip 411 is acted on, release its anchoring states with tube inner wall.
The hand well blowout preventing device of the present invention, may be implemented in the inwall grappling of oil pipe；Meanwhile, the hand well blowout preventing dress
Putting can be to oily liquid in pipe carries out blowout prevention or draining is processed at well head, in effectively preventing viscous crude, thin oil, high-solidifiability oil well operation process
The liquid flooding and blowout phenomenon of generation.
Several embodiments of the present invention are the foregoing is only, those skilled in the art is according to application documents disclosure
The embodiment of the present invention can be carried out it is various change or modification without departing from the spirit and scope of the present invention.
