Abstract
The utility model relates to a polished rod eye which automatically adjusts twisting and deflection of hair braids of an oil pumping unit and prevents back-off of a polish rod, in particular to a deviation adjustable polished rod eye. The technical scheme of the utility model is that the deviation adjustablepolished rod eye comprises hair braids, a polish rod, a square clip and apolished rod eye. The polish rod is connected with the polished rod eye through the square clip, the polished rod eye is provided with two hair braids symmetrically, and a deviation adjusting device is arranged between the polished rod eye and the square clip. An upper pressure plate and a lower pressure plate are arranged vertically on the shell. Grooves are arranged inside the upper and lower pressure plates and provided with single groove rotary discs. A double groove rotary disc is arranged between the two single groove rotary discs. A bearing frame and a steel ball are arranged between the single groove rotary discs and the double groove rotary disc. The bearing frame, the single groove rotary discs and the double groove rotary disc rotate along a sleeve. The deviation adjustable polished rod eye provided by the utility model has the beneficial effects that the deviation adjustable polished rod eye effectively overcomes the deficiency that the polished rod eye and the polish rod rotate caused by rigid strand-breaking internal force generated by wire twisting of the hair braids so as to compensate the shortage of a conventional polished rod eye.
Description
Technical field
The utility model relate to a kind of automatic adjusting oil pumper hair plait beat turn round, crooked and prevent the rope suspension apparatus of polished rod back-off, but particularly a kind of tuningout polished rod eye.
Background technology
At present, petroleum industry oil pumper and sucker rod junction are made up of hair plait, polished rod eye and square clamp.Oil pumper is when normal operation, because hundreds of meters sucker rods and ground decentraction, generation torsional forces in the pit shaft; Two hair plaits are that steel wire is turned round to compile and formed in addition; Behind bearing load, can produce brokenly a burst power, these two kinds of power can make polished rod eye and polished rod produce rotation; The hair plait is beaten and is turned round and can cause damage to the hair plait, receives pumping unit horsehead extruding, friction simultaneously; Hair pigtail and roofbolt break-off accident happen occasionally, and the hair plait is disconnected, and the well head oil spout causes the pollution of environment, and roofbolt breaks to take off and causes the oil pumper well of lying; When bringing economic loss, also have a strong impact on operative employee's safety.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, but a kind of tuningout polished rod eye is provided, and a solution hair plait invar silk is turned round the problem that the broken strand internal force of the rigidity that forms generation makes polished rod eye and polished rod generation rotation of compiling effectively.
Its technical scheme is: comprise a mao plait, polished rod, square clamp and polished rod eye, polished rod connects polished rod eye through square clamp, is symmetrical set two hair plaits on the polished rod eye; Be provided with deviation correcting device between described polished rod eye and the square clamp, described deviation correcting device is made up of housing, top board, single groove rotating disk, bearing bracket stand, double flute rotating disk, lower platen, steel ball, sleeve pipe, is provided with sleeve pipe in the middle of the housing; Polished rod passes sleeve pipe and connects polished rod eye; Housing top board and lower platen be set up and down, the inboard of described top board, lower platen is provided with groove, top board, lower platen pass sleeve pipe; The single groove rotating disk of difference in the groove of top board, lower platen; Be provided with the double flute rotating disk between two single groove rotating disks, be provided with bearing bracket stand and steel ball between single groove rotating disk and the double flute rotating disk, described bearing bracket stand, single groove rotating disk and double flute rotating disk rotate along sleeve pipe.
The beneficial effect of the utility model is: it has overcome a hair plait invar silk effectively turns round and compiles the broken strand internal force of the rigidity that forms generation and make polished rod eye and polished rod produce the shortcoming of rotation, has remedied the deficiency of traditional rope suspension apparatus.Along with the stroke up and down of oil pumper carries out tuningout automatically, sets upright.The outstanding rope of design is regulated distortion, the rotation energy imbalance that erection device can overcome polished rod eye; Reached to avoid beating and turned round the polished rod eccentric wear that causes, prolonged its application life and stop accident rate and the purpose that reduces worker's labour intensity when oil pumper taking place to improve driving a well because of the hair plait.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: hair plait 1, polished rod 2, square clamp 3, housing 4, top board 4.1, single groove rotating disk 4.2, bearing bracket stand 4.3, double flute rotating disk 4.4, lower platen 4.5, steel ball 4.6, sleeve pipe 4.7, polished rod eye 5.
The specific embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model comprises mao plait 1, polished rod 2, square clamp 3 and polished rod eye 5; Polished rod 2 connects polished rod eye 5 through square clamp 3, is symmetrical set two hair plaits 1 on the polished rod eye 5, it is characterized in that: be provided with deviation correcting device between described polished rod eye 5 and the square clamp 3; Described deviation correcting device is made up of housing 4, top board 4.1, single groove rotating disk 4.2, bearing bracket stand 4.3, double flute rotating disk 4.4, lower platen 4.5, steel ball 4.6, sleeve pipe 4.7; Be provided with sleeve pipes 4.7 in the middle of the housing 4, polished rod 2 passes sleeve pipe 4.7 and connects polished rod eyes 5, housing 4 top board 4.1 and lower platen 4.5 be set up and down; The inboard of described top board 4.1, lower platen 4.5 is provided with groove; Top board 4.1, lower platen 4.5 pass sleeve pipe 4.7, are provided with double flute rotating disk 4.4 between single groove rotating disk 4.2, two single groove rotating disks 4.2 respectively in the groove of top board 4.1, lower platen 4.5; Be provided with bearing bracket stand 4.3 and steel ball 4.6 between single groove rotating disk 4.2 and the double flute rotating disk 4.4, described bearing bracket stand 4.3, single groove rotating disk 4.2 and double flute rotating disk 4.4 rotate along sleeve pipe 4.7.
The utility model compared with prior art has following advantage: because the structure that has adopted steel ball and single, double groove rotating disk to combine; Effectively avoided the hair plait to beat to turn round and moved back button, eccentric wear phenomenon with rod string; Can overcome simultaneously distortion, the rotation energy imbalance of polished rod eye; Reached to avoid beating and turned round the polished rod eccentric wear that causes, prolonged its application life and stop accident rate and the purpose that reduces worker's labour intensity when oil pumper taking place to improve driving a well because of the hair plait.
