Description
Technical field
The utility model belongs to drilling technology field, is specifically related to a kind of bit adapter.
Background technology
Along with going deep into of oil field deep reservoir exploration and development, deep drilling quantity increases year by year, deep formation hardness is high, abrasiveness strong, drillability extreme value is high, adopt conventional drilling mode rate of penetration lower, and the rock bit life-span is shorter, frequently makes a trip, drilling rate of a trip is low, have a strong impact on deep layer drilling period, can not meet and propose effect requirement.The mud motors such as current employing helicoid hydraulic motor, turbodrill, hydraulic rotary-percussion instrument are used as speed-raising means.Weighing apparatus torque tool is exactly a kind of mud motor, is the impact energy of drill bit circumference the hydraulic energy transfer of drilling fluid, and while normal rotary drilling, circumference percussive assist drill bit breaks rock, improves drilling speed.Due to underground working more complicated, easily there is part and drop in the instrument (as striker) be thus connected with drill bit, and then affects production safety.
Summary of the invention
The purpose of this utility model is, in order to solve the instrument be connected with drill bit in drilling process, the problem that part drops easily occurs, and provides a kind of weighing apparatus torque tool pressure transmission torsion pass anti-lost joint.
The anti-lost joint of this weighing apparatus torque tool pressure transmission torsion pass comprises body, and the lower end of body is inserted with striker, and on the inwall of body lower end, level has interior annular groove, and the outer wall of striker upper end has the external annular groove relative with interior annular groove; Body has the screw communicated with interior annular groove, in screw, be connected with plug; Ball is filled with in annular space between interior annular groove and external annular groove; The lower end of body is provided with lower tooth bank, and the upper end of striker is provided with the upper tooth bank matched with lower tooth bank, is filled with ball in the horizontal blanking between lower tooth bank and upper tooth bank; The outside of the position that lower tooth bank matches with upper tooth bank is overlapped and is had sealing shroud.
The utility model has following beneficial effect:
The anti-lost joint of this weighing apparatus torque tool pressure transmission torsion pass operationally, striker can by by body moment of torsion, the pressure of the drill of passing to be delivered to by tooth down structure be connected to striker bottom drill bit on, be the powered rotation of drill bit.Tooth down structure can realize circumferential impact stroke, the circumferential impact energy provided by weighing apparatus torque tool is delivered on striker, drive drill bit while rotating, carry out the impact of circumference, balancing drill place moment of torsion, reduce the torque ripple at drill bit place, at this moment owing to having laid ball between tooth down, fitting face up and down between tooth down is contacted by original face and becomes point cantact, the uniform and stable high-frequency percussion energy that beater mechanism is produced efficiently transmits, decrease the energy loss produced because of face contact, effectively balance drill bit place moment of torsion, reduce the torque ripple at drill bit place.Mating groove between body and striker lays ball, and ball half is contained in the interior annular groove on body, and half is contained in the external annular groove on striker, and this structure can effectively prevent the parts such as striker from departing from weighing apparatus torque tool, shaft bottom of dropping.Structure of the present invention is simple, safe and reliable, achieve weighing apparatus torque tool rotates in the process of creeping into impact combine creep into form, provide powerful support for the object that weighing apparatus torque tool raises speed at hard formation, puies forward effect and reduce costs, to oil field development, there is profound significance.

Detailed description of the invention
Below in conjunction with Fig. 1 and Fig. 2, the utility model is described further:
The anti-lost joint of this weighing apparatus torque tool pressure transmission torsion pass comprises body 1, and the lower end of body 1 is inserted with striker 2, and on the inwall of body 1 lower end, level has interior annular groove 3, and the outer wall of striker 2 upper end has the external annular groove 4 relative with interior annular groove 3; Body 1 has the screw 5 communicated with interior annular groove 3, plug 6 is connected with in screw 5, be filled with ball 7 in annular space between interior annular groove 3 and external annular groove 4, adopt said structure, ball 7 to be pressed in annular space by screw 5 and to seal screw 5 with plug 6 by workman; Mating groove between body 1 and striker 2 lays ball 7, ball 7 half is contained in the interior annular groove 3 on body 1, half is contained in the external annular groove 4 on striker 2, and this structure can effectively prevent the parts such as striker from departing from weighing apparatus torque tool, shaft bottom of dropping.The lower end of body 1 is provided with lower tooth bank 8, and the upper end of striker 2 is provided with the upper tooth bank 9 matched with lower tooth bank 8, and tooth down groove circumference is 50 °, and it is 40 degree that tooth cuts protruding circumference, is filled with ball 7 in the horizontal blanking between lower tooth bank 8 and upper tooth bank 9; The outside of the position that lower tooth bank 8 matches with upper tooth bank 9 is overlapped and is had sealing shroud 10, adopt said structure, striker 2 can by by body 1 moment of torsion, the pressure of the drill of passing to be delivered to by tooth down structure be connected to striker 2 bottom drill bit on, be the powered rotation of drill bit.Tooth down structure can realize circumferential impact stroke, the circumferential impact energy provided by weighing apparatus torque tool is delivered on striker 2, drive drill bit while rotating, carry out the impact of circumference, balancing drill place moment of torsion, reduce the torque ripple at drill bit place, at this moment owing to having laid ball 7 between tooth down, fitting face up and down between tooth down is contacted by original face and becomes point cantact, the uniform and stable high-frequency percussion energy that beater mechanism is produced efficiently transmits, decrease the energy loss produced because of face contact, effectively balance drill bit place moment of torsion, reduce the torque ripple at drill bit place.Structure of the present invention is simple, safe and reliable, achieve weighing apparatus torque tool rotates in the process of creeping into impact combine creep into form, provide powerful support for the object that weighing apparatus torque tool raises speed at hard formation, puies forward effect and reduce costs, to oil field development, there is profound significance.
