Description
Technical field
The present invention relates to field of petroleum machinery, and in particular to the new paraffin scraper for embracing power is squeezed in a kind of regulation.
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 new paraffin scraper for adjusting and squeezing and embracing power, paraffin scraper is more in oil pumping pipe surface
Secondary paraffin cutting back and forth, and the sucker rod that power adaptation diameter is continually changing is embraced by adjusting squeezing for paraffin scraper, reduce the loss of blade
Degree, while avoiding damage to sucker rod.
The present invention is achieved through the following technical solutions：
It is a kind of to adjust the new paraffin scraper for squeezing and embracing power, including squeeze embrace a ring, it is blade, bolt, upper fixed support, packing ring, lower solid
Fixed rack, the crowded armful of ring embraces ring and a lower crowded armful of ring including upper squeeze, and the upper crowded ring and the lower armful ring that squeezes embraced is semi-loop, upper crowded armful
Ring and the lower armful ring that squeezes are spliced to form a domain, and upper crowded armful of ring and lower crowded embrace are evenly arranged with multiple blades on the inside of ring；It is upper to squeeze
The two ends for embracing ring are provided with fixed support, and the lower two ends for squeezing armful ring are provided with lower fixed support, corresponding upper fixation
Support and lower fixed support are bolted；Packing ring is provided between corresponding upper fixed support and lower fixed 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, the angular range between the plane of blade and crowded armful of ring axis is 0 °~90 °.Blade is sideling to set
Embraced squeezing on the inside of ring, so, blade can not just be cut to spot or wax, moreover it is possible to make blade in itself to spot or
Wax is struck off, and further improves the paraffin removal efficiency of paraffin scraper.
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, 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；
2nd, 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.
