Description
Technical field
The present invention relates to field of petroleum machinery, and in particular to a kind of online paraffin scraper of well head.
Background technology
Rod scraper, is when being used for well head raising sucker rod, the wax scraping apparatus of paraffin cutting to be carried out to sucker rod, can be scraped
Go cementing more dense wax, asphalitine and colloid on sucker rod.When carrying out paraffin cutting, well head connection body is arranged on well head
On, according to the different model of sucker rod and wax deposition situation, paraffin cutting glue core, the paraffin cutting blade of dimension are selected, is adjusted by pressure
Save leading screw timely adjustment paraffin cutting blade and a power is embraced to squeezing for sucker rod, by the hoisting mechanism of workover treatment, automatically and thoroughly
Remove the crude oil and cementing fine and close wax, asphalitine and colloid of sucker rod outer wall.Paraffin scraper present in prior art is used
Driven by power blade carries out paraffin cutting, blade is lost larger, and cost is higher, simultaneously as driven by power, blade running speed compared with
It hurry up, easily to sucker rod appearance scratch, cause the reduction of sucker rod service life.
The content of the invention
The technical problems to be solved by the invention are paraffin scrapers carries out paraffin cutting using driven by power blade, to blade loss compared with
Greatly, cost is higher, simultaneously as driven by power, blade running speed is very fast, easily to sucker rod appearance scratch, causes oil pumping
The reduction of bar service life, it is therefore intended that provide a kind of online paraffin scraper of well head, paraffin scraper is repeatedly scraped back and forth in oil pumping pipe surface
Wax, and the sucker rod that power adaptation diameter is continually changing is embraced by adjusting squeezing for paraffin scraper, the loss of blade is reduced, is kept away simultaneously
Exempt to damage sucker rod.
The present invention is achieved through the following technical solutions：
A kind of online paraffin scraper of well head, including armful ring, a blade are squeezed, the crowded armful of ring squeezes armful ring and a lower crowded armful of ring including upper,
It is upper squeeze embrace ring and it is lower squeeze that to embrace a ring be semi-loop, upper squeeze embraces ring and lower squeeze embraces a ring and be spliced to form a domain, it is upper squeeze embrace ring and
Lower squeeze on the inside of armful ring is evenly arranged with multiple blades；The blade uniformly lines up four rows, the plane of first row blade parallel to
The axis for embracing ring is squeezed, the angular range between the plane of second row blade and the axis for squeezing armful ring is in 1 °~20 °, the 3rd row's blade
Plane and the angular range squeezed between the axis for embracing ring at 21 °~40 °, the plane of the 4th row's blade embraced with squeezing ring axis it
Between angular range at 41 °~90 °.
Blade is sideling to be arranged on to squeeze to embrace on the inside of ring, and so, blade can not just be cut to spot or wax, also
Blade can be made to be struck off in itself to spot or wax, the paraffin removal efficiency of paraffin scraper is further improved.The present invention sets four row's knives
Piece, the plane of first row blade is parallel to the axis for squeezing armful ring, and first row blade can just enter to the spot or wax on sucker rod surface
Row opening, is divided into multiple parallel blocks by spot or wax；The plane of second row blade and the angle model squeezed between the axis for embracing ring
1 °~20 ° are trapped among, the spot or wax of multiple parallel blocks can just be pushed away and rolled by second row blade to a direction, multiple parallel blocks
Can somewhat it roll；Angular range between the plane of 3rd row's blade and the axis for squeezing armful ring is in 21 °~40 °, the 3rd row's blade
Angle be more than second row blade angle, the 3rd row's blade, which is further pushed away the block rolled slightly, to be rolled, and block can be rolled
It is more；The plane of 4th row's blade and the angular range squeezed between the axis for embracing ring are at 41 °~90 °, and the 4th row's blade can be by
Block is pushed away roll completely, and spot or wax are removed from sucker rod surface.
Further, the upper two ends for squeezing armful ring are provided with fixed support, and the lower two ends for squeezing armful ring are provided with lower solid
Fixed rack, corresponding upper fixed support and lower fixed support are bolted；Corresponding upper fixed support and lower fixation
Packing ring is provided between support.
The upper armful ring and the lower armful ring that squeezes of squeezing is separate, due to the spot without the oil pumping pipe surface Jing Guo any processing
It is thicker with wax, cause the diameter of oil pick-up tube to increase, therefore, when using paraffin scraper, upper crowded armful of ring and the lower armful latch closure that squeezes are being taken out
Oil pipe surface, the upper fixed support at two ends and lower fixed support can not close contact completely, so will result in squeeze and embrace
Ring and lower squeeze embrace the unstable of latch closure conjunction, therefore, packing ring are set between the upper retainer ring and lower retainer ring at two ends, make to squeeze and embrace
Ring and it is lower squeeze to embrace fit closely between ring, now, paraffin scraper is slided on sucker rod, blade can be to the spot on sucker rod surface
Or wax cutting, cause spot or wax to come off；With the progress of the cutting work of paraffin scraper, the diameter of sucker rod can diminish, this
When, upper crowded armful of ring and lower squeeze embrace being relatively large in diameter for ring, cause blade to contact spot or wax well, at this time, it may be necessary to subtract
Packing ring on less between fixed support and lower fixed support, to reduce the diameter of upper retainer ring and lower retainer ring, when upper retainer ring
It is adapted to oil pumping shank diameter instantly with the diameter of lower retainer ring, then paraffin scraper is slided on sucker rod surface, continues to cut oil pumping
The spot or wax on bar surface, repeat said process, until packing ring is removed completely.The knife edge of all blades is in same circle
On the circular arc of the heart, and when removing all packing rings, the knife edge of blade is just contacted with the surface of sucker rod.
Further, there are fixed support, packing ring, lower fixed support in hole, the screw bolt passes in the middle part of the packing ring.
Further, the packing ring is made of iron plate or steel disc.
Further, corresponding upper crowded armful of ring and the lower surface for squeezing armful ring set fluted.Groove is easy to move paraffin cutting
Device.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention is by setting multiple rows of blade, and the angle of blade is adjusted, progressively by spot and wax from sucker rod
Remove, improve paraffin removal efficiency；
2nd, in the present invention, paraffin scraper embraces a power in the multiple paraffin cutting back and forth of oil pumping pipe surface, and by adjusting squeezing for paraffin scraper
The sucker rod that diameter is continually changing is adapted to, the loss of blade is reduced, while avoiding damage to sucker rod；
3rd, the present invention sets packing ring between upper fixed support and lower fixed support, adjusts the diameter of paraffin scraper, and it is operated
Simply, it is with low cost.
