Abstract
The utility model relates to a kind of strong magnetic drilling tool Quick-installing thread of screw protecting device.Its technical scheme is: be mainly made up of thread protector body, magnet ring, steel loop, described thread protector body is the cylindrical structure of inner side for vertebral body structure, is enclosed within on the screw thread of drilling tool, sleeve pipe by the vertebral body structure of inner side; The right part of described thread protector body is provided with an inwardly radially-protruding circle boss, is embedded with the magnet ring of toroidal at boss, is embedded with the steel loop of drum at the middle part of thread protector body; The left end of described thread protector body is provided with guard circle.Beneficial effect is: link together by the magnet ring of right-hand member by thread protector body and drilling tool, sleeve pipe, do not need screwed connection, but by strong magnetic force, thread protector body and drilling tool, sleeve pipe etc. are pulled together, its dismounting is time saving and energy saving, has improved the efficiency that the thread protector of drilling tool, sleeve pipe operates; In addition, thread protector body inside studs with steel loop, can make thread protector body intensity increase, not yielding.
Description
One, technical field:
The utility model relates to a kind of oil drilling tools screw thread protection apparatus, particularly a kind of strong magnetic drilling tool Quick-installing thread of screw protecting device.
Two, background technology:
In oil drilling work progress, drilling tool, the sleeve pipe of upper and lower rig floor all need to be with thread protector, and the various thread protectors that use are at present all the thread protectors with screw thread, are not easy dismounting after distortion, and especially the screw thread of casing screw protector is many, and after distortion, dismounting is more difficult.Duo Jia OCTG factory designed, designed afterwards, also, from the external Quick-installing thread of screw protecting of introducing several structures, mainly contains cam-type and air filling type etc., but, these Quick-installing thread of screw protectings all, because complex structure, diameter are large, are not suitable with the needs of current domestic wellbore construction, so all there is no fine popularization always.
Through patent retrieval, do not find to adopt strong magnet ring to realize the thread protector such as drilling tool, sleeve pipe that wellbore construction is used.
Three, summary of the invention:
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of strong magnetic drilling tool Quick-installing thread of screw protecting device is provided, and studs with strong magnet ring structure on thread protector body, reaches the object of quickly dismantled thread protector.
Its technical scheme is: be mainly made up of thread protector body, magnet ring, steel loop, described thread protector body is the cylindrical structure of inner side for vertebral body structure, is enclosed within on the screw thread of drilling tool, sleeve pipe by the vertebral body structure of inner side; The right part of described thread protector body is provided with an inwardly radially-protruding circle boss, is embedded with the magnet ring of toroidal at boss, is embedded with the steel loop of drum at the middle part of thread protector body; The left end of described thread protector body is provided with guard circle.
Above-mentioned guard circle is made up of two semicircular ring.
The beneficial effects of the utility model are: link together by the magnet ring of right-hand member by thread protector body and drilling tool, sleeve pipe, do not need screwed connection, but by strong magnetic force, thread protector body and drilling tool, sleeve pipe etc. are pulled together, its dismounting is time saving and energy saving, improved the efficiency of the thread protector operation of drilling tool, sleeve pipe; In addition, thread protector body inside studs with steel loop, can make thread protector body intensity increase, not yielding.
Four, brief description of the drawings:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is left views of the present utility model;
Accompanying drawing 3 is that A of the present utility model is to sectional view;
Accompanying drawing 4 is that B of the present utility model is to sectional view;
In upper figure: thread protector body 1, magnet ring 2, steel loop 3, boss 4, guard circle 5.
Five, detailed description of the invention:
1-4 by reference to the accompanying drawings, the utility model will be further described:
The utility model is mainly made up of thread protector body 1, magnet ring 2, steel loop 3, and the cylindrical structure that described thread protector body 1 is vertebral body structure for inner side is enclosed within by the vertebral body structure of inner side on the screw thread of drilling tool, sleeve pipe; The right part of described thread protector body 1 is provided with an inwardly radially-protruding circle boss 4, be embedded with the magnet ring 2 of toroidal at boss, be embedded with the steel loop 3 of drum at the middle part of thread protector body 1, play powerful supporting role, can make thread protector body intensity increase, not yielding; The left end of described thread protector body 1 is provided with guard circle 5, and wherein, guard circle 5 is made up of two semicircular ring, thereby the utility model is played to better protective effect.
When use, link together by the magnet ring of right-hand member by thread protector body and drilling tool, sleeve pipe, do not need screwed connection, but by strong magnetic force, thread protector body and drilling tool, sleeve pipe etc. are pulled together, its dismounting is time saving and energy saving, improved the efficiency of the thread protector operation of drilling tool, sleeve pipe; In addition, thread protector body inside studs with steel loop, can make thread protector body intensity increase, not yielding.
