Abstract
The utility model relates to a kind of plait of pumping unit adjusters, the adjuster includes adjustment barrel, adjustable column, pin rod and baffle ring, wherein, upper and lower two groups are equipped with for installing the pin rod hole of pin rod at the middle part of adjustment barrel and lower part, outside corresponding with pin rod hole has been connected through a screw thread baffle ring, and adjustable column is located at the top of adjustment barrel, is connected through a screw thread therebetween, it is axially provided with through slot in a lateral edge of adjustable column, top is equipped with square fixed block.The adjuster realize quickly adjust the consistent purpose of hair plait length, solve mao plait because length it is inconsistent caused by discontinuity equalization, the defect to shorten the working life.Meanwhile by the setting of pin rod, a hair plait plummet is not fallen out when ensure that polished rod of pumping well lag, reduce because abjection hit cause the reductions yield occurred due to not going under polished rod and drive a well when rate situation.
Description
Technical field
The utility model belongs to oil-pumping equipment in oil field ancillary technique field, especially a kind of plait of pumping unit adjuster.
Background technique
Rod-pumped well is the main oil production equipment of current oilfield exploitation petroleum, is made of pumping unit and oil well, and connection is passed through
The cooperation of hair plait and pumping unit horsehead cambered surface between pumping unit and well rod, by the low-speed rotation of pumping unit
It is transformed into the up and down reciprocatingly property linear motion of well rod, achievees the purpose that promote downhole petroleum.Hair plait is usually one group
It two, connect with pumping unit horsehead, is connect below with the polished rod eye of well rod above, due to the work of pumping unit alternating load
With longtime running can make a mao plait discontinuity equalization, cause to deform inconsistent, the feelings of two hair plait samples different in size occur
Condition greatly increases a shorter stress, shortens service life；In addition some oil wells are due to oily sticky, under pumping unit
Well rod lags when row, keeps mao plait abjection polished rod eye too long, can hit hanging rope with hair plait when pumping unit uplink
Device causes load to increase suddenly, exacerbates a mao plait discontinuity equalization, not only shortens service life, and can break a mao pigtail
Son, single hair plait makes polished rod eye unbalance stress, and can cause not going under polished rod by polished rod stretch bending, reduces yield and drives a well
When rate.
Utility model content
The purpose of this utility model is adjusting hair plait can be facilitated long in view of the deficienciess of the prior art, providing one kind
It is short, and can prevent well rod lag from causing a mao plait of pumping unit adjuster for plait abjection.
Realize that the purpose of this utility model is adopted the technical scheme that：The adjuster includes adjustment barrel, adjustable column, pin rod
And baffle ring, wherein be equipped with upper and lower two groups for installing the pin rod hole of pin rod, with pin rod hole pair at the middle part of adjustment barrel and lower part
The outside answered has been connected through a screw thread baffle ring, and adjustable column is located at the top of adjustment barrel, is connected through a screw thread therebetween, adjusting
One lateral edge of column is axially provided with through slot, and top is equipped with square fixed block.
Every group of the pin rod is two, and the horizontal space between two pin rods is the diameter greater than hair plait, and is less than plummet
Diameter, the vertical interval between pin rod is upper and lower is 2mm~5mm greater than plummet height.
Fast velocity modulation is realized according to plait of pumping unit adjuster made of above scheme by adjusting the lifting of adjustable column
Save hair plait length purpose, solve mao plait because length it is inconsistent caused by discontinuity equalization, shorten the working life lack
It falls into.Meanwhile by the setting of pin rod, hair plait plummet is not fallen out when ensure that polished rod of pumping well lag, is reduced because de-
Hit out cause not go under polished rod and the reductions yield that occurs and when driving a well rate situation.There is the adjuster structure design to close
It manages, adjust the advantages of simple and efficient, low manufacture cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the scheme of installation of the utility model.
Specific embodiment
Referring to Fig. 1, the plait of pumping unit adjuster of the utility model, which includes adjustment barrel 6, adjustable column 4, pin
Bar 7 and baffle ring 8, wherein be equipped with upper and lower two groups for installing the pin rod hole 9 of pin rod 7, with pin at the middle part of adjustment barrel 6 and lower part
The corresponding outside of rod aperture 9 has been connected through a screw thread baffle ring 8, and adjustable column 4 is located at the top of adjustment barrel 6, passes through screw thread therebetween
Connection is axially provided with through slot 3 in a lateral edge of adjustable column 4, and top is equipped with square fixed block 2.7 every groups of the pin rod are two,
The distance between two pin rods are greater than the diameter of hair plait 1, and are less than the diameter of plummet 5, the vertical interval between pin rod 7 is upper and lower
For 2mm~5mm greater than 5 height of plummet.
Referring to Fig. 2, which is to use in pairs, in use, unloading adjustable column 4, the plummet 5 of hair plait 1 is put into tune
Between the upper and lower two groups of pin rod holes 9 for saving cylinder 6, pin rod 7 to be put on, loads onto baffle ring 8, hair plait 1 is placed in the through slot 3 of adjustable column 4,
Adjustable column 4 by being threaded into adjustment barrel 6, assembled one group of plait of pumping unit adjuster is mounted on pumping unit hanging
It restricts below device 10, the side slot 11 for making square fixed block 2 be caught in beam hanger for pumping machine 10 is fixed, adjusts side according to oil well conditions
4 high and low position of adjustable column keeps two 1 length of hair plait consistent, can come into operation, after use after a period of time, due to by
When power unevenness causes 1 length of mao plait to occur inconsistent, pumping unit load is laid down, adjusts the height of wherein side adjustable column 4 again
Lower position makes two hair plaits 1 reach length again consistent.The utility model is adjusted easily and fast by scene, makes a mao pigtail
Sub 1 length reaches requirement, and rate when improving work efficiency and driving a well reduces labor intensity.And the pin rod by being arranged,
Stop hair plait plummet not fall out when ensure that polished rod of pumping well lag, reduces and do not gone under polished rod caused by being hit because of abjection
And the situation of the reduction yield occurred and rate when driving a well.
