Abstract
A kind of eccentric abrasion prevention box cupling adjustable wrench, it is made up of fixed plate body, movable plate body, handle, boosting-rod, jump ring, leading screw, nut, attachment cap, briquetting, screw etc.Movable plate body is arranged in fixed plate body by briquetting, screw, and the movable plate body first line of a couplet has leading screw, leading screw is equipped with nut and is installed in fixed head body opening, handle is connected on fixed plate body, boosting-rod is arranged on handle by attachment cap, between handle and attachment cap, jump ring is housed, jump ring is stuck on boosting-rod.It is characterized in that: the holding workpiece place of fixed plate body, movable plate body is that four directions is annular, and do not damage eccentric abrasion prevention box cupling during work, moment of torsion is large.Feature is also: nut is arranged in fixed head body opening, rotates boosting-rod and adjustable eccentric abrasion prevention box cupling adjustable wrench clamping dimension, flexibly and easily.
Description
One. technical field
The present invention relates to---dismounting of Anti-eccentric wear coupling of sucker rod, Special tool for assembling---eccentric abrasion prevention box cupling adjustable wrench in oilfield production, maintenance.It is applicable to dismounting and the assembling of Anti-eccentric wear coupling of sucker rod in oil well production, maintenance.
two. background technology
In field produces, workover is groundwork, in the production maintenance of oil well, the eccentric wear of sucker rod and oil pipe is the Important Problems of oil well failure, the eccentric abrasion prevention box cupling of current exploitation, better address this problem, the instrument that dismounting, assembling eccentric abrasion prevention box cupling use has two kinds: (1) uses GB8406-87 type pipe tongs, be widely used because of easy to use, but the scuff-resistant coating of bad eccentric abrasion prevention box cupling easily agree by pipe tongs, produces a large amount of iron pin and burr, exacerbate the partially petty of sucker rod and oil pipe, and iron pin is fallen into oil well and is very easily damaged oil well pump; (2) be spanner.Because wrenching torque is little, and fragile, do not use now.
three. summary of the invention
Object of the present invention be exactly institute want technical solution problem be overcome above-mentioned prior art deficiency, the special tool that a kind of structure is simple, volume is little, cost is low, moment of torsion is large, easy to use, safe is provided--eccentric abrasion prevention box cupling adjustable wrench.
The technical scheme that the present invention will solve the employing of above-mentioned prior art deficiency is: a kind of eccentric abrasion prevention box cupling adjustable wrench, it is made up of fixed plate body, movable plate body, handle, boosting-rod, jump ring, leading screw, nut, attachment cap, briquetting, screw etc.It is characterized in that: movable plate body is arranged in fixed plate body by briquetting, screw, and the movable plate body first line of a couplet has leading screw, loading nut on leading screw is also installed in fixed head body opening, handle is connected on fixed plate body, boosting-rod is arranged on handle by attachment cap, and close boosting-rod, and boosting-rod front end contacts with nut, rotating boosting-rod drives nut to rotate, and between adjustment fixing plate body and movable plate body, distance clamps the eccentric abrasion prevention box cupling of different model.
Against existing technologies, during clamping work pieces work of the present invention, 1. can not gnaw bad eccentric abrasion prevention box cupling, make eccentric abrasion prevention box cupling reach designing requirement; 2. do not produce burr and iron pin, in well-repairing work, just do not have burr and iron pin can fall in oil well yet, damage oil well pump, extend oil well service time, reduce cost of production.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described
Fig. 1 is structural representation of the present invention.
1. fixed plate bodies, 2. movable plate body, 3. handle, 4. boosting-rod, 5. jump ring, 6. leading screw, 7. nut, 8. attachment cap, 9. briquetting, 10. screw in figure
Detailed description of the invention;
As can be seen from Figure 1, a kind of eccentric abrasion prevention box cupling adjustable wrench, movable plate body 2 is arranged in fixed plate body 1 by briquetting 9 screw 10, and the movable plate body first line of a couplet has leading screw 6, loading nut 7 on leading screw is also installed in fixed head body opening, handle 3 is connected on fixed plate body 1, boosting-rod 4 is arranged in handle 3 by attachment cap 8, close boosting-rod, boosting-rod front end contacts with nut, rotating boosting-rod drives nut to rotate, and between adjustment fixing plate body and movable plate body, distance clamps the eccentric abrasion prevention box cupling of different model.
Feature of the present invention is: holding workpiece place is four directions annular, and moment of torsion is large, does not damage eccentric abrasion prevention box cupling.
Another feature of the present invention is: nut is contained in fixed head body opening, rotates boosting-rod and adjustable eccentric abrasion prevention box cupling adjustable wrench clamp distance.
In workover dismounting with assembling wear-resistant collar of sucker rod, rotate boosting-rod and make eccentric abrasion prevention box cupling adjustable wrench block Anti-eccentric wear coupling of sucker rod flat mouth place, pull-out boosting-rod firmly rotates, and has come wear-resistant collar of sucker rod dismounting and assembling.
Claims (2)
1. an eccentric abrasion prevention box cupling adjustable wrench, it is by fixed plate body, movable plate body, handle, boosting-rod, jump ring, leading screw, nut, attachment cap, briquetting, screw forms, movable plate body passes through briquetting, screw is arranged in fixed plate body, and the movable plate body first line of a couplet has leading screw, leading screw is equipped with nut and is installed in fixed head body opening, handle is connected on fixed plate body, boosting-rod is arranged on handle by attachment cap, between handle and attachment cap, jump ring is housed, jump ring is stuck on boosting-rod, it is characterized in that: fixed plate body is four directions annular, movable plate body is in fixed plate body, the position of adjustment activity plate body in fixed plate body gets final product holding workpiece.
2. eccentric abrasion prevention box cupling adjustable wrench according to claim 1, is characterized in that: nut is arranged in fixed head body opening, rotates boosting-rod and adjustable eccentric abrasion prevention box cupling adjustable wrench clamping dimension.
