Abstract
A polished rod centering device of an oil pumping unit. The problem of current rod-pumped well polished rod centering be difficult to adjust is solved. The method is characterized in that: an upper flange and a lower flange (5 and 7) are welded on the clamp head (10) and the blowout preventer (1) respectively, four long round holes (4) are uniformly distributed on the upper flange (5), the long round holes (4) are parallel to each other, four round holes (6) corresponding to the upper flange (5) are formed in the lower flange (7), a sealing gasket (2) is arranged between the upper flange and the lower flange (5 and 7), and the upper flange and the lower flange (5 and 7) are connected through the long round holes (4) and the round holes (6) by bolts (3) and nuts (8). The device can adjust the centering problem of beam-pumping unit polished rod fast, and convenient operation, swift, simple, very effect has improved work efficiency greatly moreover, and workman's intensity of labour is also low.
Description
Technical field:
The utility model relates to the device that oil recovery field, oil field pumpingh well well head is adjusted polished rod, belongs to the oil-extractor polish-rod centralising device.
Background technology:
At present, the rod-pumped well in the oil recovery field, polished rod and blowout preventer at the well head place misalign, and cause the eccentric wear of polished rod.Adjust now the method for polished rod, when about when misaligning, generally be the both sides jackscrew of adjusting horse head, and displacement is only adjusted to jackscrew when misaligning in front and back on axis, when displacement, move slightly and excessively will form price scissors, exceed standard.Bring very big maintenance operation workload for production crew's service worker, but also do not reach expected effect.
The utility model content:
In order to overcome the deficiency of the bad adjustment of existing rod-pumped well polished rod centering, the utility model provides a kind of oil-extractor polish-rod centralising device, and this device can solve the problem that the rod-pumped well polished rod misaligns effectively, and is simple in structure, easy to operate, alleviated maintenance mans' labour intensity greatly.
Technical solution adopted in the utility model is: this oil-extractor polish-rod centralising device comprises blowout preventer, polished rod and clip head, be welded with upper and lower flange on clip head and the blowout preventer respectively, uniformly on the upper flange have four slotted holes, and slotted hole is parallel to each other, have on the lower flange and corresponding four circular holes of upper flange, between upper and lower flange sealing mat is arranged, upper and lower flange is connected with circular hole by slotted hole with bolt, nut.
Above-mentioned said slotted hole, the edge of one of them relative upper flange in hole is the hole of slitting.
The beneficial effects of the utility model are: because this oil-extractor polish-rod centralising device, be to adopt flange to be connected between blowout preventer and clip head, and the hole on the upper flange is a slotted hole; Like this, if the polished rod of oil pumper produces the eccentric wear phenomenon, as long as the connecting bolt of two flanges is unclamped, the upper flange on the mobile blowout preventer can then, be tightened polished rod centering again with bolt.Adjust oil-extractor polish-rod with this device, simple, effectively, and also easy to operate, quick, working strength of workers is low.
Description of drawings:
Fig. 1 is a structure sectional view of the present utility model.
Fig. 2 is a upper flange plan view among Fig. 1.
Fig. 3 is a lower flange plan view among Fig. 1.
1-blowout preventer among the figure, 2-sealing mat, 3-bolt, 4-slotted hole, 5-upper flange, 6-circular hole, 7-lower flange, 8-nut, 9-polished rod, 10-clip head.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
In conjunction with a kind of oil-extractor polish-rod centralising device of Fig. 1, comprise blowout preventer 1, polished rod 9 and clip head 10, be welded with upper and lower flange (5,7) on clip head 10 and the blowout preventer 1 respectively, uniformly on the upper flange 5 have four slotted holes 4, and slotted hole 4 is parallel to each other, have on the lower flange 7 and upper flange 5 corresponding four circular holes 6, upper and lower flange has sealing mat 2 between (5,7), upper and lower flange (5,7) is connected with circular hole 6 by slotted hole 4 with bolt 3, nut 8.
In actual use, lower flange 7 is soldered on the clip head 10 of production tree, upper flange 5 is soldered on the blowout preventer 1, place sealing mat 2 in the middle of two flanges, then, adjust the position of polished rod 9 in blowout preventer 1, make polished rod 9, with bolt 3 and nut 8 two flanges are connected again just in time at the center of blowout preventer 1.When rod-pumped well when the eccentric wear phenomenon appears in polished rod 9 in the course of the work, as long as bolt 3 and nut 8 are unclamped, because the hole on the upper flange 5 is a slotted hole 4, so, can on a large scale, adjust the position of blowout preventer 1, make the center of polished rod 9 at last at blowout preventer 1.Easy to operate, quick, simple, and produce effect very much, having improved operating efficiency greatly, working strength of workers is also low.
Claims (2)
1, a kind of oil-extractor polish-rod centralising device, comprise blowout preventer (1), polished rod (9) and clip head (10), it is characterized in that: be welded with upper and lower flange (5 respectively on clip head (10) and the blowout preventer (1), 7), upper flange (5) is gone up uniform four slotted holes (4) that have, and slotted hole (4) is parallel to each other, have on the lower flange (7) and corresponding four circular holes of upper flange (5) (6), upper and lower flange (5, sealing mat (2) is arranged 7), upper and lower flange (5,7) is connected with circular hole (6) by slotted hole (4) with bolt (3), nut (8).
2, a kind of oil-extractor polish-rod centralising device according to claim 1 is characterized in that: the edge of one of them relative upper flange (5) of slotted hole (4) is the hole of slitting.
