Abstract
The utility model relates to an oil extraction tool, especially a pumping rod rotary coupling, which comprises a pumping rod (1) and a pumping rod coupling (2), a rotating mechanism (3) is arranged outside the pumping rod coupling (2), and a sand and dirty scraping device (4) is arranged outside the rotating mechanism (3). The rotating mechanism (3) is a cylinder connected with a bearing of the pumping rod coupling (2), the sand and dirty scraping device (4) is a cylinder provided with a boss and a groove which are not in parallel with the pumping rod. According to the structure, a pumping rod rotary joint can enable an automatic rotating apparatus outside thereof to automatically rotate by the fluid flow impacting force when moving vertically following with the pumping rod. The utility model has advantages that 1. the pumping rod rotary coupling has the strengthening function and can prevent the unidirectional bias-wearing to an oil conduit by the coupling; 2. the pumping rod rotary coupling has the sand and dirty scraping function; 3. the oil flowing channel design can improve the flowing speed, and the forming of the eddy flow state can prevent the aggregating of the sand and dirty; 4. the oil pumping machine load can be reduced, and the energy can be saved.
Description
One, technical field: the utility model relates to the oil tool technical field, is specifically related to a kind of sucker rod rotation box cupling.
Two, background technology: rod collar non-directional eccentrically worn tubing inevitably takes place in the oil recovery manufacturing process, extensively adopt oil pumping rod centering device and weighted lever to alleviate the non-directional eccentric wear at present, but effect is undesirable.
Partially anti-in order to realize setting upright, the dozens or even hundreds of centralizer in a bite down-hole, there is following problem in too much use centralizer, and 1, centralizer is shorter application life, causes frequent operation; 2, reduce the aisle spare of oil circuit, reduced pump efficiency; 3, weighted lever increases the oil pumper load, causes that roofbolt is disconnected to take off.The sucker rod swivel joint can overcome the above problems preferably.
Three, summary of the invention: the purpose of this utility model is exactly to prevent partially in order to realize setting upright, solve the problem that rod collar and oil pipe non-directional eccentric wear cause frequent operation, provide a kind of simple in structure, with low cost, can have the function of setting upright, prevent that box cupling is to the sucker rod of the non-directional eccentric wear of oil pipe rotation box cupling.Its technical scheme is: sucker rod rotation box cupling comprises sucker rod, rod collar, is provided with rotating mechanism outside rod collar, and rotating mechanism is provided with the scraper of strike-ofing outward.Described rotating mechanism is the cylindrical shell that is connected with the rod collar bearing, and the scraper of strike-ofing is that cylindrical shell is provided with outward and uneven boss of sucker rod and groove.The utility model compared with prior art, have simple in structure, easy to use, with low cost and the sucker rod swivel joint with the sucker rod up-downgoing time, utilize liquid stream impulse force that its outside automatic rotating device is rotated automatically.First: have the function of setting upright, prevent the non-directional eccentric wear of box cupling to oil pipe; The second, have and strike-off, scrape dirty function; Three, flow oily channels designs, improve flow velocity, form the eddy flow state, prevent the sand scale cohesion.Four, reduce oil pumper load, energy conservation.
Four, description of drawings
Fig. 1 is the utility model structural representation;
Five, the specific embodiment
With reference to Fig. 1, sucker rod rotation box cupling comprises sucker rod 1, rod collar 2, is provided with rotating mechanism 3 outside rod collar 2, the rotating mechanism 3 outer scrapers 4 of strike-ofing that are provided with.Described rotating mechanism 3 is the cylindrical shell that is connected with rod collar 2 bearings, the stream oil passage that the scraper 4 of strike-ofing forms with uneven boss of sucker rod and groove for cylindrical shell is provided with outward.The sucker rod swivel joint utilizes liquid stream impulse force that its outside automatic rotating device is rotated automatically with the sucker rod up-downgoing time, plays and sets upright, and strike-offs, scrapes dirt, and sand control coagulates, and reduces the oil pumper load.
Claims (2)
1. a sucker rod rotation box cupling comprises sucker rod (1), rod collar (2), it is characterized in that: be provided with rotating mechanism (3) outside rod collar (2), the outer scraper of strike-ofing (4) that is provided with of rotating mechanism (3).
2. sucker rod rotation box cupling according to claim 1, it is characterized in that: the cylindrical shell of described rotating mechanism (3) for being connected with rod collar (2) bearing, the scraper of strike-ofing (4) is provided with outward and uneven boss of sucker rod and groove for cylindrical shell.
