Specific work process：
Hydraulic giant 17 is stretched out and is fixed：Complete hydraulic mining needed for drilling after, by the mechanical retractable hydraulic giant transfer to
Bottom hole, then drilling machine continue to be fed, so that high-pressure water pipe 2 is moved downward, since high-pressure water pipe 2 and bias take over 10 are taken over by bias
Clamping screw 9 connects, therefore under the drive of high-pressure water pipe 2, eccentric water pipe 10 moves downward, and drives the sliding being welded thereon
Plate 19 moves downward, at this point, the gear 20 on sliding panel 19 is rotated down along rack 8；Under the drive of link mechanism, hydraulic giant 17
Protruding certain angle, the height transferred by controlling high-pressure water pipe 2, so that it may to realize the control for stretching out angle to hydraulic giant 17
System.When the stretching angle of hydraulic giant 17 reaches design angle, brake system control valve is opened, accumulator control valve is opened simultaneously,
Hydraulic oil enters hydraulic cylinder 23 through top hydraulic tube 3, hydraulic tube chicksan 4, lower hydraulic pipe 22, and piston rod is pushed to make
24 locking gear 20 of brake block, prevents its rotation, to the stretching angle of fixed hydraulic giant 17.For the guarantor for making hydraulic system stablize
A constant pressure is held, overflow valve and accumulator are set in earth's surface hydraulic system, hydraulic system can be realized by overflow valve
Constant pressure, system pressure pulsation can be reduced by adding accumulator, increase the stability of system pressure.
17 rotating-spray detritus of hydraulic giant：After stretching angle in hydraulic giant 17 reaches requirement and fixes, adjusted by drilling machine
Hydraulic giant 17 is along the rotary speed of drilling axis, while high pressure water connects by high-pressure water pipe 2, bias take over 10, pistol high-pressure rotary
First 18 flow into hydraulic giant 17, are sprayed from the nozzle at high speeds of hydraulic giant 17, fractured rock, during hydraulic giant 17 turns round broken rock, in height
Under the action of pressure pipe rotary joint 5, first high-pressure water pipe on 5 top of rotary joint for high pressure water pipe does not turn, high-pressure water pipe rotation
Second high-pressure water pipe of 5 lower part of connector is rotated together with hydraulic giant 17, equally, under the action of hydraulic tube chicksan 4, on
Portion's hydraulic tube 3 does not turn, and lower hydraulic pipe 22 is rotated with hydraulic giant 17, realizes high-pressure water pipe 2 and the single action of hydraulic tube.When waterpower is broken
When detritus mining area domain meets design requirement, the stretching angle of hydraulic giant 17 need to be adjusted, at this point, again transferring drilling tool to bottom hole, is adjusted
Brake system control valve makes brake block 24 unclamp gear 20, transfers high-pressure water pipe 2, increases water after the stretching angle of hydraulic giant 17
Rifle 17 is fixed, and fractured rock is continued.
Hydraulic giant 17 is withdrawn：After the completion of exploitation or because when abnormal conditions need to carry brill in hole, needing the hydraulic giant 17 that will be stretched out
It withdraws, at this point, being first shut off accumulator control valve, is then shut off hydraulic pump, makes hydraulic system off-load, to which brake block 24 unclamps
Gear 20, upper raising pressure pipe 2, gear 20 is moved upwards along rack 8, passes through sliding panel 19, monitor rotary joint 18, top
Bars 16 etc. drive hydraulic giant 17 to withdraw.
In conclusion the utility model proposes a kind of mechanical retractable hydraulic giant advantage based on rack pinion such as
Under：
1, the stretching angle of the mechanical retractable hydraulic giant is cooperated control by gear 8 and rack 20, can with step-less adjustment,
On the one hand the problem of high pressure water energy caused by avoiding submerged jets drastically weakens；On the other hand, one borehole water is increased
The region of power exploitation, to improve the production efficiency of hydraulic borehole mining.
2, mechanical retractable hydraulic giant stretching is retracted through gear 20, rack 8 and the control of hydraulic giant brake system, because
This hydraulic giant 17 can be withdrawn when arbitrary need, and be avoided when there is emergency case in hole, hydraulic giant 17, which cannot be withdrawn, to be caused to bore
The problem of tool can not be promoted.
