Abstract
The utility model provides a roller side's bushing device of restricting admittedly, including base and cylindrical sleeve, its characterized in that: cylindrical sleeve is fixed on the base, and the bottom of base is provided with the hole, is provided with the screw thread on the interior pore wall, and the top of base sets up solid rope ware, is provided with fixed otic placode on the ware admittedly restrict, is provided with the earhole on the fixed otic placode, the top of ware sets up and to prevent jumping the clamp plate admittedly restrict, admittedly restrict the ware with prevent jumping the clamp plate and all overlap and establish on cylindrical sleeve, telescopic upper end sets up the through -hole, prevents jumping the safety catch and alternates in the through -hole, the utility model discloses fixed operation is simple, convenient, swift, low in labor strength, and safe and reliable has not only shortened the activity duration greatly, and the altitude range of kelly requires more in a flexible way moreover, have the wire rope function of not haring and prevent to pop out etc. Can the wide application in the high pressure, highly contain sulphur, the operation of high -yield oil gas well.
Description
Technical field
The utility model relates to solid rope device, is specifically related to the solid rope device of roller square filling core.
Background technology
In kelly bar drillng operation, particularly " three Gao Jing ", strata pressure is high, high sulfur-bearing, high-yield well, the feature that natural gas slippage with pressure is risen, after preventing closing well, uplifting pressure is greater than crown drill tool or hydrogen sulfide hydrogen embrittlement drilling tool in drilling tool weight, cause drilling tool weightless, the stuck card operation of kelly bar need be adopted, because kelly bar lower end is connected to protection joint, lower cock, load elevator on roller bushing and rotating disk, the first-class position that stacks up of drilling rod connecting is relatively high, dead card self is heavier, install, fastening bolt, the work that fixing wire rope etc. are loaded down with trivial details, operating time is longer, larger risk is brought to well control work.When adding screw rod drill rat hole with kelly bar in addition, kelly bar is fixing more difficult, and intricate operation, security performance is poor, as in drill rat hole process, adopts white palm rope to fix the mode of the reaction torque of kelly bar, when mobile white palm rope is solid, danger is comparatively large, and the personnel that very easily cause injure.
Utility model content
Technical problem to be solved in the utility model is to provide roller square filling core solid rope device, replaces original four hold-down nuts of roller square filling core.
In order to solve the problem, according to the technical solution of the utility model, the solid rope device of roller square filling core, comprise base and cylindrical sleeve, it is characterized in that: cylindrical sleeve is fixed on base, the bottom of base is provided with endoporus, inner hole wall is provided with screw thread, the top of base arranges rope fixture, rope fixture is provided with fixing otic placode, and fixing otic placode is provided with earhole; The top of rope fixture arranges anti-jump pressing plate, and rope fixture and anti-jump pressing plate are all set on cylindrical sleeve, and the upper end of sleeve arranges through hole, and anti-jump safety plug interts in through hole.
The utility model easily can install rope fixture.Because sleeve is cylindrical, rope fixture rotation direction can meet fixed angle arbitrarily, and the shackle of fixing wire rope front end is connected with becket bridle, can meet fixing wire rope angle up and down; Install anti-jump pressing plate again above rope fixture, anti-jump pressing plate mainly prevents rope fixture from ejecting, and anti-jump safety plug prevents anti-jump pressing plate from exiting.Further, after having linked closely, do not drill through and can protect screw mandrel screw thread due to endoporus not by slurry erosion.
The beneficial effect of the solid rope device of roller square filling core described in the utility model is: the utility model fixed operation is simple, convenient, fast, labour intensity is low, safe and reliable, not only substantially reduce the activity duration, and the altitude range of kelly bar requires more flexible; There is wire rope do not damage and prevent the functions such as ejection, the Oil/gas Well operation of high pressure, high sulfur-bearing, high yield can be widely used in.
Accompanying drawing explanation
Fig. 1 is the structural representation of the solid rope device of roller square filling core described in the utility model.
Detailed description of the invention
See Fig. 1, the solid rope device of roller square filling core, comprise base 4, cylindrical sleeve 5, rope fixture 3, anti-jump pressing plate 2 and anti-jump safety plug 1, cylindrical sleeve 5 is fixed on base 4, the bottom of base 4 is provided with endoporus 7, inner hole wall is provided with screw thread 6, and the top of fixing screw mandrel 11 base 4 arranges rope fixture 3, rope fixture 3 is provided with fixing otic placode 8, fixing otic placode 8 is provided with earhole; The top of rope fixture 3 arranges anti-jump pressing plate 2, and rope fixture 3 and anti-jump pressing plate 2 are all set on cylindrical sleeve 5, and the upper end of cylindrical sleeve 5 arranges through hole, and anti-jump safety plug 1 interts in through hole.Base 4 can be six water caltrops, is convenient to spanner fastening roller bushing gland.
During embody rule, original for roller square filling core four hold-down nuts are changed into and uses this fastening devices, when being fixed kelly bar, fastening devices is fixed on the screw mandrel 11 of roller square filling core by screw thread 6, rope fixture 3 is enclosed within cylindrical sleeve 5, more anti-jump pressing plate 2 is enclosed within cylindrical sleeve 5, insert anti-drop safety pin 1, dismantle becket bridle 9 and penetrate fixing wire rope 10, then becket bridle 9 is worn pin with the earhole on fixing otic placode 8 be connected, complete kelly bar well head and fix.Adopt the utility model, make to be that dead cassette roller square filling core changes multi-functional roller square filling core into originally, add the function of roller square filling core on original basis.
