Abstract
The utility model relates to a sucker rod reversing device used in oil field workover treatmen. The utility model is composed of slips, clamping bodies, a rotatory pipe, screws and baffle plates, wherein the clamping bodies are connected with the end part of the rotatory pipe; the slips are arranged in the clamping bodies; the screws fix the baffle plates on the clamping bodies; the baffle plates are positioned outside the slips. When the utility model is used, the clamping bodies are connected into a whole by screw assemblies above the clamping bodies to make the slips of the clamping bodies enclasped and clamped on the inverse sucker rod; the sucker rod and the utility model can not rotate correspondingly; a pair of hydraulic tongs for dismounting oil pipe buckles clamps the rotatory pipe, and the pair of hydraulic tongs is started to make the rotatory pipe rotate reversely so as to reversely dismount sucker rod buckles. The utility model has the advantages that reversing work does not need to be carried out by manpower with pipe tongs, the operators have no danger and the human casualty accidents can not occur.
Description
Affiliated technical field:
The utility model is the sucker rod reverse buckling equipment that oil well repairing operation is used, and belongs to engineering goods.
Background technology:
In oil field pumping well was produced, along with the deep exploitation of oil well, formation sand production was more and more serious, the problem of sand card oil well pump often occurs, and oil well is forced to stop production, and needed operation to trip out oil well pump in the well.But because pump has been blocked by sand, the piston of oil well pump is carried to be come out, and has only at the scene could put forward the oil well pump piston the sucker rod back-off.Be that operating worker is stuck in inverted sucker rod realization back-off on the sucker rod with pipe wrench to the sucker rod back-off method of being blocked at present, when torque reaction reaches one regularly, pipe wrench and sucker rod problem of slip appear sometimes, sucker rod discharged moment of torsion after pipe wrench and sucker rod skidded, produce rotation at a high speed, easily operating worker is damaged, at the scene, the sucker rod back-off is breakneck work, human casualty accident repeatedly occurs.
Summary of the invention:
The purpose of this utility model provides a kind of sucker rod reverse buckling equipment, makes it can be not dangerous in the sucker rod back-off, human casualty accident can not occur.
The purpose of this utility model is achieved in that it is made up of slips, card body, swinging head, screw, baffle plate.Card sports association is connected on the swinging head end, and slips is placed in the card body, and screw is fixed on baffle plate on the card body, and baffle plate is in the slips outside.During use, the card body is connected into one by the bolt group on it, its slips is embraced done the card jail on quilt falls sucker rod, sucker rod can not rotate relatively with the utility model, the hydraulic tongs that will be used to dismantle tubing thread again blocks swinging head, starts hydraulic tongs and makes the swinging head counter-rotating, thereby unload the sucker rod button.
The beneficial effects of the utility model: do not need manually to use the pipe wrench back-off, the operator is not dangerous, human casualty accident can not occur.
Description of drawings:
Fig. 1 is a complete section assembled view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
The specific embodiment:
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Among the figure: the 1st, slips, the 2nd, card body, the 3rd, swinging head, the 4th, screw, the 5th, baffle plate.As seen from the figure, the utility model is made up of slips 1, card body 2, swinging head 3, screw 4, baffle plate 5.Card body 2 is connected in swinging head 3 ends, and slips 1 is placed in the card body 2, and screw 4 is fixed on baffle plate 5 on the card body 2, and baffle plate 5 is in slips 1 outside.During use, card body 2 is connected into one by the bolt group on it, make 1 armful of its slips do the card jail on quilt falls sucker rod, sucker rod can not rotate relatively with the utility model, the hydraulic tongs that will be used to dismantle tubing thread again blocks swinging head 3, start hydraulic tongs and make swinging head 3 counter-rotatings, thereby unload the sucker rod button.
