Description
Technical field
The utility model belongs to the maintenance tool of oil field shaft mouth rotary self-closing well closing appts, particularly rotates self-sealing core and takes out instrument, can take out the self-sealing core in rotary self-closing well closing appts fast.
Background technology
Rushing to summit in oil well reconditioning service, mainly dependence kelly bar is self-styled as EGR of shunting in a well by rotating for salvaging, construction such as cover milling, milling etc., has carried out the periodic duty of workover fluid.To a certain degree just there will be poorly sealed, phenomenon such as thorn leakages etc. when self-sealing core may wear to, directly affect construction quality, so change the day-to-day work that rotation self-sealing core is overhaul team.
Adopt metallic framework owing to rotating self-styled self-sealing core, to be circular configuration rotated in self-styled upper circular groove with rotating self-styled shell interference fit and to be pressed in by self-sealing core by 8 screws with platen with twice O cushion rubber on its top.Owing to there is no specific purpose tool, generally take the method that hammer, crowbar are prized when taking self-sealing core.Or adopt and be fixed on well head by self-styled for rotation, will by major diameter instrument with workover rig
its self-sealing corethe method of taking out.Because self-sealing core elasticity is large, screen resilience is large, said method take self-sealing core waste time and energy, expend time in long, to get core process loaded down with trivial details, labour intensity is large, directly affects efficiency of construction.Job site needs a kind of specific purpose tool rotating self-sealing core that takes to solve this difficult problem, produces actual needs with satisfied.
Summary of the invention
The purpose of this utility model is to provide and rotates self-sealing core taking-up instrument, and solve the practical problem that rotary self-closing well closing appts self-sealing core takes out difficulty, improve maintenance efficiency, reduction labour intensity, ensures the repair quality of rotary self-closing well closing appts.
Technical solution of the present utility model is: rotate self-sealing core taking-up instrument and comprise pull bar, carrier, support and lifting assembly, the top body of rod of pull bar is provided with external screw thread and is connected with the swivel nut promoting assembly, and pull bar passes from the centre bore of support, its lower end is connected with carrier; Mounting handle on the swivel nut promoting assembly.
The beneficial effects of the utility model are: the structure of this instrument is simple, reasonable in design, easy to operate; Processing and manufacturing cost is low, the usage safety performance of instrument is high.Take self-sealing core speed fast, not only reduce the labour intensity of workman, improve operating efficiency, also protect other parts of self-sealing blowout preventer simultaneously, improve repair quality, and shortening accounts for the well cycle.The utility model result of use obviously, there is good using value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing in detail the utility model is described in detail, and unrestricted protection domain of the present utility model.See Fig. 1, rotate self-sealing core taking-up instrument and comprise pull bar 4, carrier 6, support 3 and promote assembly 2, the top body of rod of pull bar 4 is provided with external screw thread and is connected with the swivel nut promoting assembly 2, and pull bar 4 passes from the centre bore of support 3, its lower end is connected with carrier 6; Mounting handle 1 on the swivel nut promoting assembly 2.Promote assembly 2 and comprise swivel nut, pressure cap and supporting seat, the center screw of swivel nut is connected with pull bar 4, and swivel nut is arranged in supporting seat and is fixed by pressure cap, and pressure cap is threaded with supporting seat.Swivel nut is ladder cylindrical, the cylindrical step mounting handle 1 on top, installs bearing in the cylindrical step both sides of bottom, and swivel nut can be made rotatable when rotating, and reduces the wearing and tearing with supporting seat.Support 3 comprises fagging and screw rod, screw rod two ends are equipped with screw thread, two screw rods are arranged on the two ends of fagging, the spacing of two screw rods is equal with the spacing of the diagonal angle screw of self-sealing blowout preventer platen, this instrument can be fixed on the platen of rotary self-closing well closing appts by screw rod.Carrier 6 comprises righting sleeve 5 and chassis, and righting sleeve 5 welds with chassis.The lower end of pull bar 4 is threaded with carrier 6 or nut is installed again in the lower end of pull bar 4 after the centre bore of carrier 6 passes, and carrier 6 and pull bar 4 is linked together.
During use, rotary self-closing well closing appts is kept flat, the lower end of pull bar 4 being passed from rotating the self-sealing core of self-styled envelope device and carrier 6, playing centralizing function bottom the endoporus making righting sleeve 5 penetrate self-sealing core, also avoiding self-sealing core elastic deformation greatly to the loss of upper top power simultaneously.Rotary self-closing well closing appts is placed vertically, by pull bar 4 righting after being connected with pull bar 4 by carrier 6.In the diagonal angle screw of rotary self-closing well closing appts overhead platen, tighten two screw rods, pull bar 4 is introduced in the swivel nut of lifting assembly 2.The supporting seat of lifting assembly 2 is made to press close to the fagging of support 3.Rotary handle 1, rotarily drives by pull bar 4 that carrier 6 is up withstands self-sealing core.Continue rotary handle 1, under the lifting pulling force effect of pull bar 4, the rebound performance making self-sealing core overcome self outwards ejects, and completes the process of taking out and rotating self-sealing core.
