Abstract
The utility model discloses a kind of polished rod eye, comprise the upper mounted plate and bottom plate that be arranged in parallel, upper mounted plate and bottom plate two ends are respectively arranged with symmetrical U-type groove, centre is provided with through hole, sucker rod is fixed with in through hole, also comprise polished rod slips and lower polished rod slips, upper polished rod slips blocks sucker rod and is placed on upper mounted plate, lower polished rod slips blocks sucker rod and is placed between upper mounted plate and bottom plate, also comprise two horsehead ropes, each root in two horsehead ropes passes the U-type groove of upper mounted plate and bottom plate homonymy successively.A kind of polished rod eye, between upper mounted plate and bottom plate, be provided with one group of polished rod slips in addition, when solid failure to sucker rod of the polished rod slips of higher level, the polished rod slips of subordinate just can play a role, and prevents sucker rod to fall well, in addition, this device simple installation, dismounting easily, are easy to promote.
Description
Technical field
The utility model belongs to extracting device of oil field, relates to a kind of polished rod eye.
Background technology
In the petroleum industry oil pumper course of work, R a T is the vitals recovered the oil, and wherein, pumping unit horsehead polished rod eye is the flexible connecting member connecting polished rod and horse head, bears the stress alternation of pumpingh well.
The connected mode of horsehead rope hanger and sucker rod mainly comprises the formula of wearing, side-mounted, positive-installed etc., polished rod slips block sucker rod and fixing with it after, rely on sucker rod and downhole gravity to be positioned on horsehead rope hanger.This to be connected and fixed mode easy to be quick detachable, locates solid and reliable.But polished rod slips, on the contact surface of itself and sucker rod, has the card tooth of high rigidity, when polished rod slips blocks sucker rod, be rely on sucker rod and downhole gravity to make polished rod slips be positioned horsehead rope hanger, make sucker rod adeciduate.Therefore, the contact surface of polished rod slips and sucker rod will produce stress and concentrate, easily cause fracture, sucker rod occur and to fall the accident of well.
Utility model content
The purpose of this utility model is to provide a kind of polished rod eye, and the contact surface upper stress solving polished rod slips and sucker rod is concentrated, and then causes the problem of rod broken.
The technical scheme that the utility model adopts is: a kind of polished rod eye, comprise the upper mounted plate and bottom plate that be arranged in parallel, upper mounted plate and bottom plate two ends are respectively arranged with symmetrical U-type groove, centre is provided with through hole, sucker rod is fixed with in through hole, also comprise polished rod slips and lower polished rod slips, upper polished rod slips blocks sucker rod and is placed on upper mounted plate, lower polished rod slips blocks sucker rod and is placed between upper mounted plate and bottom plate, also comprise two horsehead ropes, each root in two horsehead ropes passes the U-type groove of upper mounted plate and bottom plate homonymy successively.
Feature of the present utility model is also:
Upper mounted plate and bottom plate are respectively rectangle.
Ejector pin is provided with between upper mounted plate and bottom plate.
The place that horsehead rope contacts with upper and lower fixing plate is provided with bolt.
Horsehead rope lower end is provided with steel wire loop.
The beneficial effects of the utility model are: a kind of polished rod eye of the utility model; in normal operation; upper polished rod slips, upper mounted plate are in running order; lower polished rod slips, bottom plate are in empty configuration state; when there is stress concentration phenomenon in upper polished rod slips and sucker rod contact surface and rupture; lower polished rod slips and bottom plate then play a role, and effectively prevent sucker rod and to fall the accident of well, form the protection in second defence line to coming off of sucker rod.In addition, this device simple installation, dismounting easily, are easy to promote.
Accompanying drawing explanation
Fig. 1 is the longitudinal sectional drawing of a kind of polished rod eye of the utility model;
Fig. 2 is the upward view of upper mounted plate in a kind of polished rod eye of the utility model;
Fig. 3 is the top view of bottom plate in a kind of polished rod eye of the utility model.
In figure, 1. horsehead rope, 2. upper mounted plate, 3. ejector pin, 4. bottom plate, 5. bolt, 6. steel wire loop, 7. sucker rod, 8. go up polished rod slips, 9. plays polished rod slips.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of polished rod eye, as Figure 1-3.Comprise the upper mounted plate 2 and bottom plate 4 that be arranged in parallel, upper mounted plate 2 and bottom plate 4 two ends are respectively arranged with symmetrical U-type groove, centre is provided with through hole, sucker rod 7 is fixed with in through hole, also comprise polished rod slips 8 and lower polished rod slips 9, upper polished rod slips 8 blocks sucker rod 7 and is placed on upper mounted plate 2, lower polished rod slips 9 blocks sucker rod 7 and is placed between upper mounted plate 2 and bottom plate 4, also comprise two horsehead ropes 1, each root in two horsehead ropes 1 passes the U-type groove of upper mounted plate 2 and bottom plate 4 homonymy successively, upper mounted plate 2 and bottom plate 4 are rectangle, ejector pin 3 is provided with between upper mounted plate 2 and bottom plate 4, horsehead rope 1 is with upper, bottom plate 2, the place of 4 contacts is provided with bolt 5, horsehead rope 1 lower end is provided with steel wire loop 6.
During use, steel wire loop 6 on horsehead rope 1 is stuck in matrix counterbore, horsehead rope 1 is positioned, polished rod slips 9 blocks sucker rod and is positioned over above bottom plate 4, does not contact, in empty configuration state with bottom plate 4, in the course of work, if sucker rod 7 is disconnected de-from upper polished rod slips 8 lower end, this at present polish rod clamp watts 9 can fall within bottom plate 4, sucker rod 7 just can work on.
A kind of polished rod eye of the utility model; in normal operation; upper polished rod slips, upper mounted plate are in running order; lower polished rod slips, bottom plate are in empty configuration state; when there is stress concentration phenomenon in upper polished rod slips and sucker rod contact surface and rupture; lower polished rod slips and bottom plate then play a role, and effectively prevent sucker rod and to fall the accident of well, form the protection in second defence line to coming off of sucker rod.
