Description
Technical field
The utility model relates to a kind of density skeleton crossover sub extracting tool.
Background technology
Density skeleton and crossover sub be field of oil drilling conventional with drill tools.There is the joint pin of a protrusion one end of density skeleton, is provided with an annular opening piston ring on joint pin surface.Crossover sub is a columniform workpiece, and centre is through hole, has a circle cable-through hole on the circumference between through hole and external diameter, on the inner hole wall of one end of crossover sub, has an annular groove.In the time that density skeleton is connected with crossover sub, the annular opening piston ring of density skeleton is just in time installed to the annular groove the inside of crossover sub.After the annular opening piston ring of density skeleton coordinates with the annular groove of crossover sub, cannot take apart with hand or non-specific purpose tool.The effect of this annular opening piston ring is for protection is outside dismounting skeleton when drill collar; prevent that skeleton from departing from together with drill collar; because there are a lot of cables to be communicated with between crossover sub and skeleton, as skeleton, disengaging together with drill collar can cause cable to break, and can cause serious consequence to instrument.
In prior art, generally take the annular opening piston ring of density skeleton and the annular groove of crossover sub apart with screwdriver, the position, gap that a word position of screwdriver is stuck between crossover sub and density skeleton is pried open.Taking by the mode that this screwdriver is pried open that crossover sub is connected with skeleton apart is the poor efficiency of requiring great effort very much, but also dangerous.
Therefore, need a kind ofly to save time, density skeleton crossover sub extracting tool laborsaving, easy to operate and safe.
Utility model content
An object of the present utility model is to provide a kind of density skeleton crossover sub extracting tool.
Density skeleton crossover sub extracting tool of the present utility model is characterised in that and comprises:
Handle (1);
Pull-out leading screw (2), its one end is provided with opening, and described handle (1) is connected with described pull-out leading screw (2) through described opening;
Threaded block (3), it is arranged on the other end of described pull-out leading screw (2);
Thrust bearing (6), it is arranged on described pull-out leading screw (2);
Connecting cylinder (4), it holds described pull-out leading screw (2), described threaded block (3) and described thrust bearing (6), and described pull-out leading screw (2) is arranged on one end of described connecting cylinder (4);
Snap ring (5), it is arranged on the other end of described connecting cylinder (4).
Preferably, described threaded block (3) comprises that two half-unit divides, and is provided with two annular boss on the lateral surface of described threaded block (3).
Preferably, described half part is semicircular.
Preferably, described snap ring (5) comprises that two half-unit divides, and on the medial surface of described snap ring (5) and lateral surface, is equipped with annular boss.
Preferably, described half part is semicircular.
Density skeleton crossover sub extracting tool of the present utility model can disassemble crossover sub safe and reliable, convenient and swift, time saving and energy savingly, has greatly improved operating efficiency.
Brief description of the drawings
Fig. 1 is according to the perspective view of the density skeleton crossover sub extracting tool of embodiment of the present utility model;
Fig. 2 is according to the profile of the density skeleton crossover sub extracting tool of embodiment of the present utility model.
Detailed description of the invention
Below with reference to Fig. 2, density skeleton crossover sub extracting tool of the present utility model is described.
Handle (1) is connected with pull-out leading screw (2) through the opening on pull-out leading screw (2) one end.On pull-out leading screw (2), be provided with thrust bearing (6) and be connected with thrust bearing (6) by screw thread.The other end of pull-out leading screw (2) is provided with threaded block (3) and is connected with threaded block (3) by screw thread.Threaded block (3) comprises two semicircular half parts, is provided with two annular boss on the lateral surface of threaded block (3).Snap ring (5) comprises two semicircular half parts, on the medial surface of snap ring (5) and lateral surface, is equipped with annular boss.
Before dismounting, first two annular boss of threaded block (3) are stuck in the seal groove of outstanding joint face of the lateral surface of crossover sub (not shown), then with bolt, two semicircular half parts are connected and tighten formation one, extracting tool is stuck on crossover sub.Then, the annular boss on the medial surface of snap ring (5) is stuck in the outside O type ring recess of density skeleton (not shown).The medial surface of connecting cylinder (4) is enclosed within on the annular boss on the lateral surface of snap ring (5), extracting tool can be stuck on density skeleton.When connecting cylinder (4) is stressed, the annular boss of snap ring (5) lateral surface can withstand connecting cylinder (4).The pull-out leading screw (2) of connecting cylinder (4) one end screws with threaded block (3) screw thread, can connect.
When dismounting, turn clockwise handle (1) (, to left movement), pulling out leading screw (2) drives threaded block (3) and crossover sub to move to the direction of handle (1), now the other end of connecting cylinder (4) withstands on snap ring place, and the thrust that connecting cylinder (4) is subject to pulling out leading screw (2) can be blocked density skeleton by snap ring (5) and move right.Now crossover sub will be coordinated the annular opening piston ring disengaging of locking to split with density skeleton, thereby realize disassembling function.
In sum; these are only preferred embodiment of the present utility model; be not intended to limit protection domain of the present utility model; therefore; all any amendments of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model within spirit of the present utility model and principle.
