7. in the time that piston 11 is operated in the backhaul period, when compressed air promotion piston 11 moves to the right, also round about (in left side, boring) is to cylinder block 10 and the whole device application of force except piston 11, now due to the without hindrance effect of contraction that pushes away of ratchet 2, make whole device to boring 38 interior movements, drill bit 22 is always kept in touch with the bottom of boring 38.
By some impact rotating working cycles, whole device constantly advances to direction reach at the bottom of hole, realizes the self-propelled rock drilling drilling function without outside other thrust.
8. when after boring end-of-job, make the pawl end of ratchet 2 depart from the hole wall of boring 38 by point stay cord 7 and the main stay cord 6 that are connected on each ratchet 2, and whole device is drawn and draws off boring 38.
In addition, it is adjustable that electromagnetic coil 18 energization excitation frequencies and hollow shaft stepper motor 13 rotate step pitch, thereby the anglec of rotation can change the frequency of impact of drill bit 22 to rock and a working cycles according to different on-the-spot ROCK CONDITIONS time, this function can adopt prior art to complete.
The critical piece material of device can be selected: distribution inner tube 24 adopts high permeability materials (or its nearly electromagnetic coil 18 end suitable length sections adopt high permeability materials, remainder adopts general stainless steel); Distribution outer tube 25 adopts general stainless steel; The thrust moving to direction at the bottom of hole for increasing impact dynamics and drilling tool, piston 11 is filled out the material (as lead etc.) with larger specific gravity except adopting the material of larger strength and stiffness impacting end, can inlaying therein, to increase its quality; The material of ratchet 2 can adopt carbide alloy; Divide stay cord 7 and main stay cord 6 to adopt stainless steel twisted wire; Impact the material that power transmission part 20 adopts larger strength and stiffness; Drill bit 22 can be conventional drill material.In addition, electromagnetic coil 18 and hollow shaft stepper motor 13 all need waterproof sealing.
Except introducing the pipeline of required drive, whole rock drill aperture apparatus is all placed in big gun hole, and when blasthole drilling cutter, required impact force, revolute function and end thrust provides by the mechanism being placed in boring.
As shown in Figure 1, 2, 3, multiple ratchets 2 are installed in the detent recess 3 in constrainer 1 periphery with revolute pair connected mode; Goring push spring 4 is installed in goring push spring installing hole 5, ratchet 2 is axially no less than two groups along constrainer 1, every group is upwards arranged symmetrically with more than 3 in constrainer footpath, in its group number and group, number is determined according to the fragmentation of rock or cranny development degree, more broken or the crack of rock is compared with under developmental condition, in group number and group, number can be many, otherwise can lack.For being easy to, whole device draws off the big gun hole that Drilling is good, each ratchet 2 is connected with point stay cord 7, divide the other end of stay cord 7 to be connected with the main stay cord 6 that is arranged in main stay cord duct 8 through point stay cord duct 9 in constrainer 1, for making ratchet 2 depart from the hole wall of boring 38;
As shown in Fig. 2,4,5,6,7, valve actuating mechanism adopts center gas distribution channels mode, coaxial distribution inner tube 24 and distribution outer tube 25 are set on the central axis of cylinder block 10, piston 11 is socketed on distribution outer tube 25 by mesopore, on distribution inner tube 24 and distribution outer tube 25, be positioned at the axial both sides of piston 11 and have stroke air inlet (distribution duct II 27 and distribution duct III 28), backhaul air inlet (distribution duct V 30 and distribution duct VI 31), and also have stroke vent (distribution duct VII 32) in the leading section entity part of distribution inner tube 24; Between distribution inner tube 24 and distribution outer tube 25, between distribution outer tube 25 and piston 11, be tightness contact, and can be free to slide in the axial direction, to reach hole distribution to promote the object of piston 11 drill hammers; For ensureing backward stroke of the piston air inlet and stroke exhaust, on impact power transmission part 20, also have gas distribution channels (distribution duct IV 29); Also be provided with piston 11 backhaul gas exhausting valves 15 on the right side of piston 11, on it, have vent (valve body exhaust duct 16), and be equipped with backhaul vent (distribution duct XI 42) and (the cylinder shell exhaust duct 17) in cylinder block 10, jointly provide piston 11 backhaul exhaust passages; Electromagnetic coil arranges in chamber 39 electromagnetic coil 18 of installing distribution inner tube 24 pulling force that slides axially to the right in distribution outer tube 25 is provided, the returning spring 19 at electromagnetic coil 18 centers provides distribution inner tube 24 thrust that slides axially left in distribution outer tube 25, backward stroke of the piston gas exhausting valve 15 is fixed in distribution inner tube 24, is synchronized with the movement with distribution inner tube 24.The slew gear of drill bit is made up of distribution outer tube 25, impact power transmission part 20, connecting pin 23 and hollow shaft stepper motor 13.
When operation, for the many big guns hole shallow bore hole rock drilling of meeting head on when tunnelling in underground mining operation, first designing position Drilling prebored hole with traditional hammer drill, its degree of depth should be equal to or greater than the length of self-propelled rock drill aperture apparatus, again self-propelled rock drill aperture apparatus is placed in prebored hole, connects that power is calmed the anger, dust suppression temperature lowering water and power supply.After whole prebored holes in whole meet head on one driving circulation can disposable Drilling complete, more multiple self-propelled rock drill aperture apparatus are inserted in each prebored hole and worked simultaneously.Be advanced to after set depth until self-propelled rock drill aperture apparatus; from boring, draw off before self-propelled rock drill aperture apparatus again; should first shut down; draw off, its unloading method is again: with a rigid bar of being longer than boring, one end is inserted and in boring, withstood self-propelled rock drill aperture apparatus afterbody; strain main stay cord 6 and point stay cord 7 of ratchet 2 simultaneously; the pawl end of ratchet 2 is separated with the hole wall of boring 38, keep the tensioning state of stay cord, until self-propelled rock drill aperture apparatus is drawn off.
The invention has the beneficial effects as follows: this device only needs with after the prebored hole suitable with this device length of the prior depth drilled of traditional hammer drill, just can in hole, automatically advance and carry out rock drilling boring without mechanism arrangement outside traditional hole, simple in structure, cost is lower, can on narrower and small work plane, work by multiple devices simultaneously, greatly reduce the bore operation time, reduce operating personnel's labour intensity, also can greatly reduce working-noise simultaneously.
