Abstract
The utility model relates to a tool used for oil field well repairing operation, in particular to a mine mouth oil pipe fixed slip device which has the technical proposal that the utility model comprises a slip seat, a slip body, a slip tooth and a slip drive mechanism. The lower part of the inner wall of the fixed slip seat is of a cylinder shape, the upper part is of a conical surface which is matched with the slip body, the slip body is partially of a conical ring structure, the middle part of the transect at the outer side is of a dovetail structure, which is matched with a dovetail groove at the inner wall of the slip seat, the slip tooth is embedded into a groove at the inner side of the slip body, and the slip tooth is partially of a stepped ring structure. The utility model has the advantages that the slip is fixed firmly, thereby no sloughing phenomena occurs; a hydraulically powered control mechanism can be convenient to realize the manual control or automatic control; when the operation for the oil pipe and a sucker rod is performed, only the slip tooth is needed to be changed, the work efficiency is high, and the work intensity and risk of workers can be reduced.
Description
One, technical field:
The utility model relates to a kind of oil well repairing operation instrument that is used for, and particularly relates to a kind of well head oil pipe stationary slip device.
Two, background technology:
At present the stationary slip that well head uses in the well workover of oil field is fixed on the bottom of tubing coupling after involutory by two groups of slips, need Manual Switch oil pipe or sucker rod slips during use, working strength is big, inefficiency, oil pipe be can't dock, even oil pipe or sucker rod obscission occurred.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of high efficiency is provided, and can reduce working strength of workers and dangerous well head oil pipe stationary slip device.
Its technical scheme is: comprise slip spider, slips body, slip insert and slips driving mechanism composition, stationary slip seat inwall bottom is cylindrical, top is the taper seat that cooperates with the slips body, the slips body is a part conical ring structure, middle part, cross section, the outside is the dovetail structure, cooperate with the dovetail groove of slip spider inwall, slip insert embeds in the groove of slips body inboard, is part cascade ring structure.
The slips driving mechanism comprises cylinder, slips drive rod, gas pressure regulator composition, the respective drive cylinder of each slips body is installed in the respective cylinder installing hole of slip spider, cylinder piston rod top links to each other with the slips drive rod, and the slips drive rod inserts in the chute of slips body.
The beneficial effects of the utility model are: obscission, can not take place in the slips fixation; The hydraulic-driven controlling organization can make things convenient for Artificial Control or realize control automatically; During to oil pipe and sucker rod operation, only need to change slip insert, high efficiency can reduce working strength of workers and danger.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a B-B sectional structure schematic diagram among Fig. 2.
Five, the specific embodiment:
Shown in accompanying drawing, comprise slip spider 1, slips body 2, slip insert 3 and slips driving mechanism.The lower end is and well head tubing hanging seat flange connecting that the upper end is and other parts flange connecting.Stationary slip seat 1 outer body is cylindrical, slip spider inwall bottom is cylindrical, top is the taper seat that cooperates with slips body 2, slips body 2 is a part conical ring structure, make by high strength steel, middle part, cross section, the outside is the dovetail structure, cooperate with the dovetail groove of slip spider 1 inwall, slips body 2 can slide up and down along slip spider 1 inwall, slip insert 3 embeds in the groove of slips body 2 inboards, for part cascade ring structure, is made by iron base friction plate, inwall chucking oil pipe or sucker rod 13, slip insert 3 can be changed according to different work object (oil pipe or sucker rod).The slips driving mechanism is made up of the parts such as pad 12 of nut 4, packing ring 5, bolt 8, packing ring 9 and the sealing usefulness of cylinder 7, slips drive rod 6, pneumatic cylinder controller 11, gas circuit 10 and connection usefulness, the respective drive cylinder 7 of each slips body 2 is installed in the respective cylinder installing hole of slip spider 1, cylinder 7 piston rod tops link to each other with slips drive rod 6, slips drive rod 6 inserts in the chute of slips body 2, motion with cylinder 7 piston rods, drive slips body 2 and slip insert 3 and move up and down, the round internal diameter that slip insert 3 inwalls form enlarges or dwindles.
