Abstract
The utility model relates to the quick rountrip device of a kind of oil well.Its technical scheme is: support assembly is tubular construction, oil pipe is through the inner chamber supporting assembly, and the bottom supporting assembly is flexibly connected with preventer, and slips body is installed on the top supporting assembly, the center of slips body is provided with a circle slip insert, is coordinated with oil pipe by slip insert; The top fixed support axle of described support assembly, lower sides is fixed the base of cylinder, described cylinder is flexibly connected with one end of connecting rod by pull bar, and the other end of connecting rod is flexibly connected with the second rotating shaft being fixed on slips body top, and middle part and the back shaft of connecting rod are connected.Beneficial effect is: by installing cylinder at the lateral wall supporting assembly, cylinder is connected with connecting rod by pull bar, and then drive slips body movable, and the center of slips body is provided with a circle slip insert, so the screw thread achieving oil pipe fast tightens, improve operating efficiency and workmanship, reduce labour intensity, decrease potential safety hazard.
Description
Technical field
The utility model relates to a kind of oil well instrument, particularly the quick rountrip device of a kind of oil well.
Background technology
In field produces operation process, during oil pipe is gone into the well by screwed connection, can screw thread tighten and directly have influence on construction quality, but in well workover process, can only tighten upper screw thread by hydraulic tongs, can not tighten lower screw thread.
Chinese patent literature publication number 203308435U, patent name is " a kind of well workover pipe string fast ", comprises wire rope, sleeve pipe, sand bucket piston, tapping valve, sand bucket pump barrel, sand screen, drag for sandpipe, drag for sand valve, drift size gauge tool, pipeline scraper, nib, sand post, tapping valve is arranged on sand bucket piston, and sand bucket piston is arranged in sand bucket pump barrel, and the top of sand bucket piston is connected with wire rope bottom, sand bucket pump barrel, drag for sandpipe, drag for sand valve, drift size gauge tool, pipeline scraper, nib connects successively, and sand screen is in and drags in the top of sandpipe, and sand screen top is connected with sand bucket pump barrel, wire rope, sand bucket piston, tapping valve, sand bucket pump barrel, sand screen, drag for sandpipe, drag for sand valve, drift size gauge tool, pipeline scraper, enter on the sand post in sleeve pipe under after nib links into an integrated entity, with entering whole instrument under wire rope, equipment removes soon, and can carry out dragging for sand simultaneously, pipe cleaning, drifting, energy workover treatment fast, can reduce flow chart, saves operating cost, alleviates labor strength, have significant economic benefit.
Its Problems existing is: in oil well repairing operation, operation or pretty troublesome, and do not have special power tool, its working strength is large, and there is potential safety hazard.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of oil well quick rountrip device, can tighten oil pipe two ends screw thread easily, improve operating efficiency, reduce labour intensity.
Its technical scheme is: comprise and support assembly, slips body, cylinder, pull bar, connecting rod, the first rotating shaft, back shaft, the second rotating shaft, slip insert, described support assembly is tubular construction, oil pipe is through the inner chamber supporting assembly, the bottom supporting assembly is flexibly connected with preventer, slips body is installed on the top supporting assembly, the center of slips body is provided with a circle slip insert, is coordinated with oil pipe by slip insert; The top fixed support axle of described support assembly, lower sides is fixed the base of cylinder, described cylinder is flexibly connected with one end of connecting rod by pull bar, and the other end of connecting rod is flexibly connected with the second rotating shaft being fixed on slips body top, and middle part and the back shaft of connecting rod are connected.
The lateral wall of above-mentioned support assembly is provided with groove, groove internal fixtion cylinder.
The beneficial effects of the utility model are: by installing cylinder at the lateral wall supporting assembly, cylinder is connected with connecting rod by pull bar, and then drive slips body movable, and the center of slips body is provided with a circle slip insert, so the screw thread achieving oil pipe fast tightens, improve operating efficiency and workmanship, reduce labour intensity, decrease potential safety hazard.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is a portion of the present utility model enlarged drawings;
In upper figure: preventer 1, support assembly 2, slips body 3, cylinder 4, pull bar 5, connecting rod 6, oil pipe 7, first rotating shaft 8, back shaft 9, second rotating shaft 10, slip insert 11.
Detailed description of the invention
By reference to the accompanying drawings 1 and 2, the utility model will be further described:
The utility model comprises support assembly 2, slips body 3, cylinder 4, pull bar 5, connecting rod 6, first rotating shaft 8, back shaft 9, second rotating shaft 10, slip insert 11, described support assembly 2 is tubular construction, oil pipe 7 is through the inner chamber supporting assembly, the bottom supporting assembly 2 is flexibly connected with preventer 1, slips body 3 is installed on the top supporting assembly 2, the center of slips body 3 is provided with a circle slip insert 11, is coordinated with oil pipe 7 by slip insert 11; The top fixed support axle 9 of described support assembly 2, lower sides is fixed the base of cylinder 4, described cylinder 4 is flexibly connected with one end of connecting rod 6 by pull bar 5, the other end of connecting rod 6 is flexibly connected with the second rotating shaft 10 being fixed on slips body 3 top, and middle part and the back shaft 9 of connecting rod 6 are connected.
Wherein, particularly, the lateral wall supporting assembly 2 is provided with groove, and groove internal fixtion cylinder 4, its structure is more reasonable.
The utility model is by installing cylinder at the lateral wall supporting assembly, cylinder is connected with connecting rod by pull bar, and then drive slips body movable, and the center of slips body is provided with a circle slip insert, so the screw thread achieving oil pipe fast tightens, improve operating efficiency and workmanship, reduce labour intensity, decrease potential safety hazard.
