On；During hydraulic mining, broken landwaste is returned through scum pipe 3 by drilling fluid carrying and is discharged to earth's surface.
Specific work process of the invention:
Hydraulic giant 12 is stretched out and is fixed:, will be under the self-action hydraulic mining drilling tool after the drilling needed for completing hydraulic mining
It puts to bottom hole, under the drive of drill string, protection pipe 22 rotates clockwise therewith, thus rotated clockwise with active toothed disk 18, when
When fluted disc 18 goes to the region of engagement with gear 19, gear 19 is rotated clockwise, and the poke rod of gear 19 is stirred pull rod 17 and transported upwards
Dynamic certain distance, under the drive of pull rod 17, drawing plate 8 moves up same distance, thus drive sliding panel 14 to move up by connecting rod 9,
At this point, the mandril 13 being mounted on sliding panel 14 supports the protruding certain angle of hydraulic giant 12, when fluted disc 18 turns over region of engagement,
The holding of gear 19 does not turn, and the stopping of pull rod 17 moves upwards, and under the action of rubber sleeve 15, sliding panel 14 axially retains motionless, from
And the stretching angle of hydraulic giant 12 is fixed, when fluted disc 18 goes to region of engagement, repeat above-mentioned movement；Due to protection pipe 22 and top cover
Single action bearing 21 is connected between 1, so in 22 rotation process of protection pipe, top cover 1 and be connected on top cover 1 it is first high
Pressure pipe 5, scum pipe 3 do not rotate with it, and due to being provided with annular groove on drawing plate 8, rotate in drawing plate 8 with protection pipe 22
When, the ball 16 being connected on pull rod 17 slides in annular groove, to ensure that pull rod 17 is not rotated with drawing plate 8；It is logical
The size of region of engagement or the size of drill string rotational speed on adjustment gear 19 and fluted disc 18 are crossed, the stretching of hydraulic giant 12 can be realized
The upper of sliding panel 14 can be calculated by gear 19 and the meshing relation of fluted disc 18 and the revolution of drill string in speed from earth's surface
Distance is moved, to obtain the real-time stretching state of hydraulic giant 12.
12 rotating-spray detritus of hydraulic giant: earth's surface high-pressure water is through the first high-pressure water pipe 5, chicksan 6, the second high pressure
Water pipe 7, angle coupling 10, monitor rotary joint 11 flow into hydraulic giant 12, spray from the nozzle at high speeds of hydraulic giant 12, meanwhile,
Under the drive of protection pipe 22, the second high-pressure water pipe 7, drawing plate 8, connecting rod 9, angle coupling 10, monitor rotary joint 11, water
Rifle 12, mandril 13, sliding panel 14 and rubber sleeve 15 rotate with it, to realize 12 rotating-spray detritus of hydraulic giant；Due to protection pipe
It is connected with single action bearing 21 between 22 and top cover 1, so in 22 rotation process of protection pipe, top cover 1 and is connected to 1 on top
The first high-pressure water pipe 5, scum pipe 3 do not rotate with it, due to the effect of chicksan 6 and ball 16, ensure that first
The components such as high-pressure water pipe 5, pull rod 17 are not rotated with protection pipe 22, realize single action purpose.
Hydraulic giant 12 is withdrawn: after the completion of exploitation or because needing the hydraulic giant 12 that will be stretched out when abnormal conditions need to mention brill in hole
It withdraws, at this point, stopping drilling tool rotation, closes well head, turn down the discharge capacity of slush pump, decentralization scum pipe 3 is allowed to connect with drawing plate 8
Touching, at this point, fluid flow paths are obstructed, since the radius of drawing plate 8 and sliding panel 14 is respectively less than protection pipe 22, so, it is pressing
Under the action of difference, drawing plate 8 and sliding panel 14 are moved downward, and are observed and are pumped in earth's surface, when pump pressure increases suddenly, illustrate to stretch
Plate 8 is contacted with the limit film for being welded on the second high-pressure water pipe 7, i.e., hydraulic giant 12 reaches retracted state.
In conclusion self-action hydraulic mining drilling tool advantage proposed by the present invention is as follows:
1, the stretching angle of self-action hydraulic mining drilling tool of the invention is controlled with gear 19, fluted disc 18 and drilling tool revolving speed
On the one hand system avoids the problem of high pressure water energy caused by submerged jets sharply weakens convenient for adjusting；On the other hand, increase
The region of one borehole hydraulic mining, to improve the production efficiency of hydraulic borehole mining.
2, self-action hydraulic mining drilling tool of the invention controls the stretching of hydraulic giant 12 by gear 19, fluted disc 18 etc., is not necessarily to
On ground, the stretching of hydraulic giant 12 is can be realized in table handling, and the process that can simplify hydraulic mining reduces the labor intensity of operator.
3, self-action hydraulic mining drilling tool of the invention can be withdrawn at any time, when engineering occurs abnormal, can and
When withdraw hydraulic giant, drilling tool is promoted, so as to increase the reliability and applicability of the self-action hydraulic mining drilling tool.
