Limit protrusion is provided with the lower hammer;Impact boss is symmetrically arranged with end face on the inside of limit protrusion.
The impact boss is slope surface boss.
The turbine wheel shaft middle part radial equipartition has flowing hole.
The fixed disk is fixedly connected with shell, and fixed disk is slidably connected with upper hammer.
The beneficial effects of the invention are as follows:
The high frequency is reversed is symmetrically arranged with impact boss with the lower hammer end face of axial double direction impulse device;Every turn of upper hammer An axial impact force and torsional pulse power can be produced within dynamic one week, effectively improve the contact stress between drill bit and rock and broken hole Interior crack propagation, so as to improve the efficiency of breaking rock of drill bit, when solving traditional rotary drilling mode and encountering hard formation, drilling well The problem of efficiency reduces, and bit life shortens, and drilling period is long, of high cost;The high frequency reverses and axial double direction impulse device is carrying While high rate of penetration, torque-on-bit, angular speed and axial velocity fluctuation, and drilling tool stress fluctuation are effectively reduced, from And reduce the failure of drilling tool.There is positive dissemination to improving drilling efficiency and reducing drilling cost.

Embodiment
The high frequency reverses and axial double direction impulse device includes shell 1, connector 2, alignment bearing 3, turbine wheel shaft 4, upper hammer 5 With lower hammer 6.The threaded one end of shell 1 is provided with connector 2;The other end of shell 1 is slided by end cap 7 and buffer spring 8 Lower hammer 6 is installed.Limit protrusion 9 is provided with lower hammer 6;2 impacts are symmetrically arranged with the end face of the inner side of limit protrusion 9 Boss 10, impact boss 10 are slope surface boss.
Turbine wheel shaft 4 is provided with by nut 11 in the shell 1 of 6 side of lower hammer, turbine wheel shaft 4 is multidiameter shaft, turbine wheel shaft 4 Middle part radial equipartition has flowing hole 12.Whirlpool is provided with by symmetrically arranged alignment bearing 3 on the circumference of 4 one end of turbine wheel shaft Rotor 13 and stator 14 are taken turns,
Upper hammer 5 is slidably fitted with by connecting key on the circumference of 4 other end of turbine wheel shaft, upper hammer 5 can on turbine wheel shaft 4 Slide axially, and can be rotated with the rotation of turbine wheel shaft 4.Installation base, the upper hammer of installation base side are provided with upper hammer 5 Compression spring 16 is provided with by fixed disk 15 on body 5, tup 17, upper hammer 5 are provided with the end face of installation base opposite side It is connected by tup 17 with 6 Intermittent Contact of lower hammer.
The high frequency reverses and the fixed disk 15 of axial double direction impulse device is fixedly connected with shell 1, fixed disk 15 and upper hammer 5 Between be slidably connected.One end is connected by connector 2 with drill string when the high frequency reverses and axial double direction impulse device works, and is transmitted Drill string torque;The other end is connected by lower hammer 6 with drill bit, and transmits impact force.In the course of work, drilling fluid passes through Luo Liukong 12 enter simultaneously impulse turbine rotor 13 and stator 14 so as to drive turbine wheel shaft 4 to rotate, and then drive upper hammer 5 to rotate.This mistake Cheng Zhong, due to being provided with 2 impact boss 10 on lower hammer 6, and it is slope surface boss to impact boss 10.(Impact boss 10 most It is plane transition between high point and minimum point)For upper hammer 5 while being rotated with turbine wheel shaft 4, tup 17 on upper hammer 5 is along punching The slope surface track for hitting boss 10 is helically raised so as to be run to peak, when the track plane peak for moving to impact boss 10 During with minimum point drop position, upper hammer 5, which falls, hits lower hammer 6, is consequently formed axial impact force.
After the completion of axial impact, upper hammer 5 continues to rotate, and tup 1 is contacted with impacting the track plane of boss 10 at this time, drives Lower hammer 6 produces moment rotation, so as to form a torsional pulse power.The axial impact force and torsional pulse that the impactor produces Power cooperates, and the contact stress between drill bit and rock and the crack propagation in broken hole can be effectively improved, so as to improve brill The efficiency of breaking rock of head, when solving traditional rotary drilling mode and encountering hard formation, drilling efficiency reduces, and bit life shortens, and bores The problem of well cycle is long, of high cost;The impactor effectively reduces torque-on-bit, angular speed while rate of penetration is improved And axial velocity fluctuation, and drilling tool stress fluctuation, so as to reduce the failure of drilling tool.To improving drilling efficiency and reducing drilling well Cost has positive dissemination.
