Abstract
The utility model provides a prevent disconnected rope hanger that takes off of polished rod, by polished rod, hair pigtail pin, baffle, plumb weight, baffle set screw, prevent disconnected side checkpost, rope hanger U-shaped recess, hair pigtail draw-in groove, polished rod draw-in groove, checkpost main part are constituteed, the utility model discloses owing to adopt there is the polished rod draw-in groove at the rope hanger U-shaped recess department of checkpost main part, have the disconnection side checkpost of preventing on the polished rod of polished rod draw-in groove department, have the baffle to be connected by baffle set screw below it, have hair pigtail draw-in groove at checkpost main part symmetry, have the hair pigtail to pass through the hair pigtail pin and be connected with it, plumb weight is down connected to the hair pigtail, makes the polished rod install the disconnection side checkpost of preventing in balancing iron below U-shaped recess immediately in the twinkling of a moment after the breakage of anticipated breakpoint, and the polished. The technology can reduce the occurrence of corresponding accidents to a greater extent, can greatly save the production cost, prolong the pump detection period of the oil well and improve the production efficiency of the oil well.
Description
Technical field:
The utility model relates to a kind of downhole tool that uses in Petroleum Production, the disconnected polished rod eye that takes off of particularly a kind of anti-polished rod.
Background technology:
At present, generally the anti-breaking desorption method of the polished rod of Cai Yonging is to adopt when pumping unit horsehead is parked in bottom dead centre, the 20 centimeters side of beating clamps above polished rod sealer, and preventing that polished rod is disconnected takes off.This anti-breaking desorption method security reliability is poor, polished rod is in case disconnected taking off, and oil well then promptly stops to produce, tend to cause after disconnected the taking off smash polished rod sealer, damage deep well pump, the race greasy dirt dyes and problems such as Ka Jing, disconnected taking off causes directly losing rate decline when being oil well production, and operating cost increases.
Summary of the invention:
The purpose of this utility model is to provide a kind of anti-polished rod the disconnected polished rod eye that takes off, it can solve polished rod effectively disconnected taking off taken place, and this technology can reduce the generation of corresponding accident largely, can save production cost greatly, prolong the oil well pump detection period, rate when improving oil well production.
The purpose of this utility model is to realize like this, it is made up of polished rod, hair plait, hair plait pin, baffle plate, plummet, baffle plate fixed screw, anti-breaking off-square clamp, polished rod eye U-shaped groove, hair plait draw-in groove, polished rod draw-in groove, clip main body, polished rod eye U-shaped groove in clip main body has the polished rod draw-in groove, anti-breaking off-square clamp is arranged on the polished rod at polished rod draw-in groove place, there is baffle plate to connect under it by the baffle plate fixed screw, at clip main body symmetry hairiness plait draw-in groove, the hairiness plait is attached thereto by hair plait pin, connects plummet under the hair plait.
During work, this polished rod eye shape is as " recessed " word, wherein the part of " recessed " font polished rod eye projection can play balance and supporting role, for vacateing one section polished rod space (U-shaped groove) between polished rod eye main body and the balance iron, on this section polished rod, stamp anti-breaking off-square clamp, polished rod after the disconnected drop point fracture of estimating, be installed in below the balance iron the anti-breaking off-square clamp in the U-shaped groove immediately moment block polished rod, thereby reach the purpose of the anticreep of having no progeny.
The utility model is owing to adopt the polished rod eye U-shaped groove in clip main body that the polished rod draw-in groove is arranged, anti-breaking off-square clamp is arranged on the polished rod at polished rod draw-in groove place, there is baffle plate to connect under it by the baffle plate fixed screw, at clip main body symmetry hairiness plait draw-in groove, the hairiness plait is attached thereto by hair plait pin, connect plummet under the hair plait, moment is blocked polished rod immediately to make polished rod be installed in below the balance iron the anti-breaking off-square clamp in the U-shaped groove after the disconnected drop point fracture of estimating, polished rod breaks and does not take off, and oil well can continue to produce.This technology can reduce the generation of corresponding accident largely, can save production cost greatly, prolongs the oil well pump detection period, rate when improving oil well production.It is simple in structure, and is easy to use, is well suited for The field.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is made up of polished rod 1, hair plait 2, hair plait pin 3, baffle plate 4, plummet 5, baffle plate fixed screw 6, anti-breaking off-square clamp 7, polished rod eye U-shaped groove 8, hair plait draw-in groove 9, polished rod draw-in groove 10, clip main body 11, there is polished rod draw-in groove 10 at polished rod eye U-shaped groove 8 places in clip main body 11, anti-breaking off-square clamp 7 is arranged on the polished rod 1 at polished rod draw-in groove 10 places, there is baffle plate 4 to connect under it by baffle plate fixed screw 6, at clip main body 11 symmetrical hairiness plait draw-in grooves 9, hairiness plait 2 is attached thereto by hair plait pin 3, and the hair plait connects plummet 52 times.This polished rod eye shape is as " recessed " word, wherein the part of " recessed " font polished rod eye projection can play balance and supporting role, for vacateing one section polished rod space (U-shaped groove) between polished rod eye main body and the balance iron, on this section polished rod, stamp anti-breaking off-square clamp, polished rod after the disconnected drop point fracture of estimating, be installed in below the balance iron the anti-breaking off-square clamp in the U-shaped groove immediately moment block polished rod, thereby reach the purpose of the anticreep of having no progeny.
