Abstract
The utility model discloses a deflection preventing device for a polished rod of an oil pumping machine. The utility model uses a casing body as a main body, the upper end and the lower end of the casing body are respectively provided with source nipples which are corresponding to each other and are communicated with each other, a shaft in the horizontal direction is arranged in the casing body, the shaft is perpendicular to the line of centers of the upper and the lower source nipples and the shaft does not intersect with the line of centers, a bearing is assembled on the shaft and a pulley wheel is assembled on the bearing. The structure is simple, the use is convenient, the utility model reduces the eccentric wear of a polished rod, a well head and a packing box and the wear of a packing and the polished rod, the replacing period of the packing is extended; the utility model reduces the phenomenon of oil loss which is caused by not finding the wear of the packing or the polished rod in time and avoids environment pollution; the utility model reduces the frequency of packing replacement and packing tightening, workers' labour intensity is reduced, and the production cost is saved.
Description
Technical field
The utility model relates to a kind of sucker rod protector.
Background technology
What China's oil-field oil pumper well head was inclined to one side has about 50%, and present used oil pumping polish rod packing box, itself do not have the oil-extractor polish-rod of preventing eccentric wear function, will have following problem like this: 1, packing is short application life, because polished rod off-centre makes packing stressed irregular, quick abrasion is so need often change or tighten; Otherwise, because eccentric wear is serious, be easy to cause the packing box leakage, run oil, contaminated environment.Need firmly set upright polished rod when 2, changing packing and just can finish, operation inconvenience, difficulty is big, has not only increased cost of materials, and has strengthened labor strength; 3, packing box is oil-proof will to tighten packing in order to make, and will strengthen the friction of packing and polished rod like this, thereby increases electric current, wastes energy; 4, polished rod and packing box can cause polished rod and damage every orchid every the orchid friction, after damaging, more can accelerate by polished rod the packing wearing and tearing, damage packing that the back adds every orchid and can be pressed against in the rubber valve or be squeezed into and cause ball-and-seat to block in the oil drive back thread or measuring instrument blocks, can't operate as normal.
Summary of the invention
The utility model provides a kind of and has withstood oil-extractor polish-rod with pulley and make it to remain in the middle of the well head, reduces the eccentric wear of it and well head, packing, thereby improves the oil-extractor polish-rod deflection preventer in oil-extractor polish-rod and packing application life.
The technical solution adopted in the utility model is: the oil-extractor polish-rod deflection preventer, it is based on a housing that communicates up and down, the housing upper and lower end is respectively equipped with corresponding hickey, the axle of one horizontal direction is housed in enclosure interior, this line of centres with upper and lower hickey is vertical and non-intersect, is equipped with pulley on the axle.
During use, this oil-extractor polish-rod deflection preventer is connected between packing box and the rubber valve, polished rod passes from upper and lower hickey.When the oil-extractor polish-rod deflection preventer is installed, make pulley be in the position that one side of deflection takes place polished rod, withstand polished rod with pulley, make polished rod remain on the well head center.
The periphery radian of the radian of the chute of pulley outer rim and oil-extractor polish-rod matches.
For the ease of regulating the distance between pulley and the polished rod, make pulley can withstand polished rod all the time, thereby make polished rod remain on the well head center position, the chute of two correspondences is set on inner walls, the axle two ends are located in the chute, be provided with two in the position at respective shaft two ends on the housing wall and pass housing wall can promote the jackscrew that this slides in chute, be provided with O-ring seals between jackscrew and the housing wall.
The utility model is simple in structure, easy to use, and have the following advantages: 1) reduced the eccentric wear of polished rod and well head and packing box, reduced the wearing and tearing of packing and polished rod, made the packing replacement cycle extend, changed once in former 1-2 days, changed once in present about 2 months, and reduced the number of times of tight packing simultaneously, reduce labor strength, save production cost, but every mouthful of well economical with materials in every year is taken about 5000 yuan;
2) reduce packing or polished rod wearing and tearing back owing to finding the untimely race oil phenomenon that causes, avoided environment pollution;
3) packing box is oil-proof, and packing does not just need tension, will reduce friction like this, reduces electric current and expenditure on power;
4) polished rod non-migration adds and changes packing conveniently, and the rubber valve also is easy to close dead.
Description of drawings
Fig. 1 is a structural profile schematic diagram of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the structural representation of the another kind of embodiment of the utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, housing of the present utility model 2 upper ends are welded with hickey 1, the lower end is welded with down hickey 4, mutual correspondence of two hickeys and inside communicate, in enclosure interior the axle 5 of one horizontal direction is housed, this is 5 vertical and non-intersect with the line of centres of upper and lower hickey, is equipped with bearing 6 on spool, be equipped with pulley 7 by jump ring 8 on the bearing 6, the radian of the chute 9 of pulley outer rim and the periphery radian of oil-extractor polish-rod match.For easy to process, can establish a cover plate 3 in the housing lower end, be installed in axle 5 and pulley 7 in the housing after, cover plate 3 and housing 2 is integrally welded.
During use, this device is connected between packing box and the rubber valve, last hickey is connected with packing box, and following hickey is connected with the rubber valve, and polished rod passes from upper and lower hickey, when this oil-extractor polish-rod deflection preventer is installed, make pulley be in polished rod amesiality position takes place, and the chute of pulley withstands polished rod, by the radial thrust of pulley, make polished rod remain on the well head centre position, basic vertical up-or-down movement.Friction between polished rod and the pulley is rolling friction, and frictional force is less, can not cause damage to polished rod substantially.
Regulate the distance between pulley and the polished rod for convenience, make pulley can withstand polished rod all the time, make polished rod just in time be in the well head centre position, in embodiment two, can adopt following structure, as shown in Figure 3, on inner walls, be provided with corresponding chute 10,10 ', the axle two ends are divided in the chute, be provided with two passes housing wall can promote this jackscrew that slides 11,12 in chute in the position at respective shaft two ends on the housing wall, be provided with O-ring seals 13 between jackscrew and the housing wall, outside the O shape circle clamp nut 14 arranged.But by regulating the distance between jackscrew regulating shaft 5 and the oil-extractor polish-rod, make pulley 7 withstand the direction of polished rod skew all the time, thereby allow oil-extractor polish-rod remain on the centre position of well head packing box and rubber valve, play anti-inclined to one side effect.
