Abstract
A deviation adjusting beam hanger of a pumping unit consists of a beam hanger, a polish rod and an adjusting disc. The adjusting disc is mounted on the beam hanger and provided with an advancing and retreating groove, and a circle center on an arc-shaped side surface at the end of the advancing and retreating groove is deviated from a circle center of a circular hole in the beam hanger. The adjusting disc can rotate on the beam hanger, the advancing and retreating groove on the adjusting disc rotates along with the rotation of the adjusting disc, on the condition that the polish rod is fixed, the beam hanger and the polish rod can not generate bouncing by means of rotating the adjusting disc, the polish rod can always keep vertical, a sealer of the polish rod at a wellhead is uniform in abrasion and long in use period, the wellhead of a pumping well can not leak oil, and loss of yield of the pumping well can be reduced, thereby avoiding polluting the well site of the pumping well, reducing workload, shortening oil well shutdown time and having obvious economical benefit.
Description
Technical field
The utility model is the device on the oil-field oil pumper, particularly a kind of oil pumper tuningout polished rod eye.
Background technology
Because installation quality is not high, add and work long hours, there is deflection in various degree in oil pumper, the oil pumper deflection is exactly that the oil pumper polished rod and the oil well that are connected on the oil pumper when installing misalign, or relative displacement has taken place between oil pumping unit base and the concrete pedestal polished rod and the oil well that are connected on the oil pumper are misaligned.Make the wellhead polish rod sealer wearing and tearing inhomogeneous after the oil pumper deflection; produce eccentric wear, life cycle shortens, and causes the leakage of oil of pumpingh well well head; oil well output reduces; pollute in the pumpingh well well site, environmental protection difficulty, the sealing of having to often change; workman's workload increases greatly on the one hand; Master Cost increases, and oil well stops production when changing sealing on the other hand, reduces crude output.
Summary of the invention
The purpose of this utility model provides a kind of oil pumper tuningout polished rod eye, and the position of its oil pumper polished rod eye and polished rod is transferred automatically, eliminates the wellhead polish rod sealer short problem in application life that the oil pumper deflection causes.
The purpose of this utility model has been achieved in that polished rod eye, polished rod, the adjustment dish is installed on the polished rod eye, the contact surface of adjustment dish and polished rod eye is a circular arc, has the advance and retreat groove on the adjustment dish, the center of circle that circular hole in the polished rod eye is departed from the center of circle of advance and retreat circular arc side, groove end.
The beneficial effects of the utility model are: polished rod remains vertical state during the oil pumper deflection, the wellhead polish rod sealer wearing and tearing evenly, life cycle is long, the pumpingh well well head can leakage of oil, can reduce the oil well output loss, does not pollute in the pumpingh well well site, reduces workload, reduce the oil well off-time, have remarkable economic efficiency.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the vertical view of the utility model embodiment.
The specific embodiment
Describe below in conjunction with Fig. 1,2 couples of the utility model embodiment.
As seen from the figure, embodiment of the present utility model is made up of polished rod eye 1, polished rod 2, adjustment dish 3, adjustment dish 3 is installed on the polished rod eye 1, adjustment dish 3 is a circular arc with the contact surface of polished rod eye 1, be convenient to rotation and adjustment, have advance and retreat groove 4 on the adjustment dish 3, the center of circle that circular hole in the polished rod eye 1 is departed from the center of circle of advance and retreat circular arc side, groove 4 end.Adjustment dish 3 can rotate on polished rod eye, and advance and retreat groove on the adjustment dish 34 is in company with rotating, can be by rotating adjustment dish 3 under the motionless situation of polished rod 2, make polished rod eye 1 and polished rod 2 not produce the strength of spraining, polished rod 2 remains vertical state, and the wellhead polish rod sealer wearing and tearing are even, and life cycle is long.
