Abstract
The utility model discloses an inner cylinder rotary type water-pressure rock drill using medium and low-pressure as power drive. The inner cylinder rotary type water-pressure rock drill consist of a machine head, a rotary mechanism, an impact mechanism and a machine tail, wherein the shell ends of the machine head, the rotary mechanism, the impact mechanism and the machine tail are in cup joint mutually and fastened into a whole through two long threaded rods. The utility model only needs one set of medium and low-pressure water pipeline for pressure water. Compared with the pneumatic rock drill, the inner cylinder rotary type water-pressure rock drill saves compressed air equipment and pipelines, reduces energy consumption by about two thirds, reduces noise and eliminates oil mist and dust pollution. Compared with the oil-pressure rock drill, the inner cylinder rotary type water-pressure rock drill does not need to move a high-pressure oil pump and pipelines to the operation point so as to avoid oil leakage pollution of the working site.

Hydraulic drill is comprised of head 3, fuselage (slew gear, beater mechanism), tail 23 3 parts, is anchored on one by two long bolts 30.
1, head:
Formed by water supply connector 1, control water valve 2, part annular groove and long tube 4.
2, slew gear (Fig. 2)
Minute single annular chamber, Crossed Circle chamber, many annular chambers.
Double cavity structure: the blade 7 of four rotatable certain angles (70 °-80 °), be set in wheel hub 9 (rotor) hole, garden, wheel hub is sleeved on the long tube 4 of head, pipe has endoporus to lead to press water, and there are two part annular grooves (every part annular groove accounts for 100 ° of circumference) appropriate location of its outer wall, and the porose and centre bore on long tube of this groove communicates, after blade pass is crossed spacing block, hole on wheel hub communicates with the part annular groove, and water under high pressure enters in turned cavities, makes blade rotation.
3, beater mechanism (Fig. 1, Fig. 2, Fig. 4)
By impact piston 17, rotatable inner casing 16 (inner sleeve) and outer shell 15 (shell) form.
Inner casing top and bottom have four holes (every hole is separated by 90 °, sees figure five).Upper hole numbering 1 ", 2 ", 3 ", 4 ", lower hole numbering 1 ', 2 ', 3 ', 4 '.The hole, up and down is seen from top view and is staggered 45 °.There is lobe the lower end, with revolving sleeve 20 engagements.
Outer shell is fixed, and there are eight holes top and bottom corresponding to the inner casing position, and namely every 45 ° have an inlet opening and a drain hole.Drain hole communicates with the cylinder capsule that catchments outward, is concentrated by capsule to enter return pipe.Shell have four intake tunnels (uniform every 90 °) by head part annular groove through slew gear shell (or the hole in spacing block) to the beater mechanism bottom.
4, tail
Revolving sleeve 20 is arranged in tail 23, cushion annular supercharging air cushion (energy storage) 21, thrust bearing 22, bit shank sleeve 24, annular inlet opening and water seal 25 etc.
Revolution, impact principle
1, revolution (seeing Fig. 1, Fig. 2, Fig. 6)
Revolution is four moving vanes 7 (blade be separated by 90 ° uniform) to be housed on a wheel hub (rotor) utilize water pressure pushing to complete (seeing Fig. 2).To outer wall part annular groove (porose communicating), then the aperture on wheel hub enters in annular water chamber water under high pressure, promotes blade 72,74 and stretchs out revolution by the long tube centre bore.When blade 71,73 was turned back to the drain hole position, the inlet opening on wheel hub was closed voluntarily, rotated in blade 72,74 promotion lower hub, and blade 71,73 pushes (seeing figure two, figure six) jointly at spacing block with by press water, was close on wheel hub in groove.By after spacing block, the inlet opening of its underpart is communicated with part annular groove on long tube smoothly, and blade 71,73 can be beaten voluntarily (punching) and hold revolution.When blade 72,74 forwards drain hole and spacing block position to, can re-cover blade 71,73 depress action, pass through spacing block.
Slew gear is around the long tube slow rotation, and is irreversible.
The minor axis with spline is stretched out in the wheel hub bottom, be connected with the splined hole on inner casing top, drive the inner casing synchronous revolving, the inner casing bottom has double wedge to be meshed with recessed tooth on revolving sleeve, revolving sleeve has hexagonal internal bore, the bit shank sleeve upper end is placed in this hole, and therefore, inner casing rotates and drives revolving sleeve, bit shank sleeve, drill steel rotation.
2, impact (seeing Fig. 1, Fig. 3, Fig. 4)
When inner casing rotates, four holes 1 on its top ", 2 ", 3 ", 4 " communicate with four inlet openings of outer shell (casing), press water enters inner casing top pushing piston and travels forward, meanwhile, four holes of inner casing bottom communicate with the outer shell drain hole (slightly shifting to an earlier date than top water inlet), the water discharge of inner casing bottom, piston finally hits bit shank sleeve.When inner casing is rotated further 45 °, four holes 1 ', 2 ', 3 ' of bottom, 4 ' communicate with the outer shell inlet opening, and pushing piston is (return) motion up, meanwhile, four holes on inner casing top forward the position that communicates with drain hole to, and the water in epicoele is discharged.Inner casing is rotated further, and begins next circulation.Can find out from sectional view 3, Fig. 4, inner casing often circles, piston impact four times.If the drainage hole encryption of inside and outside cylinder, the inner casing piston that often circles can impact six times or eight times, increase or reduce that outer shell is enterprising, the shared Plane Angle of drain hole (namely advancing the width of drain hole), can increase or reduce entering inner casing and intake or water discharge time.Same inner casing rotating speed increases, and also can increase frequency of impact.
Be impact force and the axial compression of damper piston idle running, buffering supercharging air cushion 13,21 and thrust bearing 12,22 are equipped with in inner casing top and revolving sleeve bottom.
The machine can empty be beaten:
The bit shank sleeve rear end gos deep into that a small distance L (Fig. 1) is arranged in ante-chamber (return chamber), not enough or do not have in the situation of thrust when end thrust, when piston hit the bit shank sleeve rear end, bit shank sleeve moved forward, to making piston directly hit revolving sleeve, and the anterior cushion pad energy storage of compression.in the time of can finding out that piston nose moves on to the revolving sleeve position on scheme, four holes 1 ' of inner casing front end, 2 ', 3 ', 4 ' sealing, water can't enter in ante-chamber, only have when air cushion expansion and hole 1, four, top ", 2 ", 3 ", 4 " when communicating with drain hole, move a segment distance on piston ability, make 1 ', 2 ', 3 ', 4 ' hole communicates with the inlet opening and enters in ante-chamber, because of time lag of opening the inlet opening, the water yield that enters ante-chamber is than normally lacking, piston return distance is also little, until during next circulation back cavity water inlet, piston can only move in one section short stroke, keep a kind of tip-tap situation.
After rig was applied certain end thrust, distance L in ante-chamber was goed deep into again in the bit shank sleeve rear end.Piston recovers proper motion.
Lubricated
The moving components such as piston, inner casing, thrust bearing all adopt the butter press injecting type lubricated.
Boring row powder
The inlet channel bottom has aperture and the part annular groove in Small Holes and tail to communicate, and enters bit shank sleeve center → drill steel through the aperture on bit shank sleeve and rinses borehole row powder, cooling drill bit at the bottom of centre bore → hole.
Anti-corrosion
The hydraulic drill inner chamber is full of the ponding easy-to-rust.Another parts preferably adopt stainless steel processing.If more for a long time need not place, after operation is complete, should connects oil pressure pipe and beat the several seconds, get rid of (displacement) chamber internal water accumulation.Connect penstocks before using next time and beat the several seconds, discharge side inner engine oil splendid attire, next time is standby.
Embodiment and method:
One, water supply and draining
1, the hydraulic pressure that uses of the utility model is 2MPa～6MPa.If adopt high-power hammer drill, can increase hydraulic pressure.
