Abstract
The utility model discloses a hanger for protecting a polish rod of a pumping well, which comprises a righting plate 1, a main body 2, an isolated body 3, stop pins 4 and a locating pin 5, wherein the righting plate 1 has a rectangular platy structure and is positioned at the upper part, the left end of the righting plate 1 is provided with a short U-shaped groove e, and the right end thereof is provided with a long U-shaped groove d; both the main body 2 and the isolated body 3 have a T-shaped structure; the left end of the main body 2 is provided with a contraction-end groove b; a semicircular through hole is arranged at the bottom of the groove b; the right end of the main body 2 is provided with a semicircular hanging rope through hole c with round steps; the left end of the isolated body 3 is provided with the semicircular hanging rope through hole c with round steps, a semicircular through hole is arranged on the T-shaped top end thereof; and the T-shaped top end of the isolated body 3 is inserted in the groove b of the main body 2, a polish rod through hole a is formed at the center thereof, a locating pin 5 is used for positioning the T-shaped top, and the stop pins 4 are arranged at the outer ends of the isolated body 3 and the main body 2. As for the hanger, when one hanging rope is broken, the hanger is automatically released from the middle, thus preventing the polish rod from bending by pulling and the machine from overturning, saving costs of the machine and the rod, and having remarkable economic benefit.
Description
One, technical field:
The utility model relates to the outstanding anti-curved technology of polished rod of having no progeny of restricting of oilfield pumping well, particularly is a kind of rod-pumped well polished rod protection hanger.
Two, background technology:
At present, in the oil field pumping well manufacturing process, use the outstanding rope of double joint, when fracture took place an outstanding rope, polished rod eye one side was subjected to outstanding rope pulling force upwards, be subjected to the downward pulling force of fluid column load in roofbolt and the well in the middle of the polished rod eye, moment changes level and with the polished rod stretch bending, makes the oil well can't ordinary production, need change polished rod during recovery, especially turn over the machine accident for the heavier rod-pumped well of load owing to discontinuity can cause, had a strong impact on crude oil production.Thereby prior art can not address the above problem.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, behind the outstanding fracture of rope of designing, can throw off a kind of rod-pumped well polished rod protection hanger of protection polished rod immediately.
Rod-pumped well polished rod protection hanger technical scheme is as follows: comprise righting board, main body, chorista backing pin, alignment pin; Its righting board is the cuboid platy structure, and left end is provided with the short groove of " U " shape, and right-hand member is provided with " U " shape elongated slot, is positioned at top, makes hanger stressed evenly; Main body and chorista (3) profile is "T"-shaped structure, and the main body left end is provided with the reducing groove, is provided with half-round cross hole in the bottom of groove, and right-hand member is provided with the outstanding rope of the semicircle through hole of band step cutting pattern; The chorista left end is provided with the outstanding rope of the semicircle through hole of band step cutting pattern, "T"-shaped top is provided with half-round cross hole, insert in the groove of main body on the "T"-shaped top of chorista, locate by alignment pin, in be formed centrally the polished rod through hole, so that polished rod is passed through, be respectively equipped with backing pin in the outer end of chorista and main body, so that outstanding rope is played protective action.
The beneficial effects of the utility model are: in the pumpingh well manufacturing process, when fracture takes place in an outstanding rope, polished rod eye one side is subjected to outstanding rope pulling force upwards, polished rod eye was thrown off automatically from middle moment, prevented the polished rod stretch bending, avoided outstanding fracture of rope of rod-pumped well of heavy load to turn over the machine accident and took place, reduce and stop the well time, improve the pumpingh well crude output, save and change polished rod, the expense of changing planes, remarkable in economical benefits.
Four, description of drawings:
Fig. 1-the utility model The field schematic diagram.
The assembling plan view of main body 2 and chorista 3 among Fig. 2-Fig. 1.
The vertical view of righting board 1 among Fig. 3-Fig. 1.
Fig. 4-outstanding fracture of rope schematic diagram of the utility model The field.
In the accompanying drawing, 1-righting board, 2-main body, 3-chorista, 4-backing pin, 5-alignment pin, the outstanding rope of 6-, 7-polished rod; A-polished rod through hole, b-groove, c-through hole, d-" U " shape elongated slot, the short groove of e-" U " shape.
Five, the specific embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model is further described:
This rod-pumped well polished rod protection hanger comprises: righting board 1, main body 2, chorista 3, backing pin 4, alignment pin 5; The righting board 1 of its cuboid platy structure is positioned at top, make hanger stressed evenly, the short groove e of left end " U " shape blocks the outstanding rope in the left side, right-hand member " U " shape elongated slot d blocks the outstanding rope in the right by polished rod, backing pin 4 is put at two ends respectively, and insert among the groove b of main body 2 on the "T"-shaped top of chorista 3, and polished rod passes from center polished rod through hole a, load onto testing arrangement, the side's of tightening clamp gets final product.When work, when causing wherein outstanding rope 6 fractures owing to reasons such as oil pumper overload, lifting rope long fatigue damages service time, when only having the outstanding rope 6 of another root to bear load, the main body 2 and the chorista 3 of rod-pumped well polished rod protection hanger separate immediately, outstanding rope 6 disconnected sides partly come off, polished rod and hanger break away from and drop to well head voluntarily, thereby realize preventing the production accident that polished rod is caused by stretch bending.
