Description of drawings
Accompanying drawing is a structural scheme of mechanism of the present utility model;
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail: impact rotating single tube casing drilling tool is that the bullet fastening position joint 2 by upper end threaded 1 is connected with bullet card chamber 8 by screw thread 7, bullet card chamber 8 is connected with slip female joint 18 by screw thread 16, slip female joint 18 lower ends are connected with slip male joint 20 upper ends by male and female spline 19, slip male joint 20 lower ends are connected with power transmission short tube 23 by screw thread 22, spear-head 3 is fixing with recovery tube 5 by spearhead connecting pin 4, the bullet positioning clamp 9 that contracts is fixed on bullet and contracts in the positioning supporting frame 13 upper end central channels by playing bayonet lock 10 and tension spring 6, recovery tube 5 covers on bullet the contract outside of positioning supporting frame 13 of positioning clamp 9 and bullet of contracting, there is cutting 31 at recovery tube 5 two ends, recovery tube 5 is connected by sliding pin 11 and the bullet positioning supporting frame 13 that contracts, it is characterized in that bullet locating rack 13 lower ends of contracting are connected with beater mechanism at the bottom of the hole 21 by screw thread 15, power transmission short tube 23 is connected with outer drill bit 26 by screw thread 24, beater mechanism 21 lower ends are connected with interior drill bit 27 by screw thread 34 at the bottom of the hole, interior drill bit 27 is connected with outer drill bit 26 by torsion pass mechanism 25 at the bottom of the hole, and the flow channels 29 that plays in the fastening position joint 2 is passed through circulation channel 30,32,12, water conservancy diversion sealing 17, flowing hole 14, beater mechanism air inlet port 33 connects to form with beater mechanism 21 at the bottom of the hole.
Before drilling construction begins, inner tube assembly can be earlier the face of land or in the hole by play fastening position joint 2 and bullet contract positioning clamp 9 be positioned at outside in the pipe assembly.In inner tube assembly arrives outer pipe assembly during the precalculated position, the bullet positioning clamp 9 that contracts opens automatically by tension spring 6, and limits on the inner tube assemblies and move by playing fastening position joint 2.And slide this moment female joint 18 and slip male joint 20 be also with crossing 19 engagements of male and female spline, the interior outside keyway of torsion pass mechanism 25 engagement that also puts in place at the bottom of the hole.When beginning to creep into, connect the internal flush drill pipe that adapts by the screw thread 1 that plays joint 2 upper ends, fastening position.Playing fastening position joint 2 is connected with bullet card chamber 8 by screw thread 7, bullet card chamber 8 is connected with slip female joint 18 by screw thread 16, slip female joint 18 lower ends are connected with slip male joint 20 upper ends by male and female spline 19, slip male joint 20 lower ends are connected with power transmission short tube 23 by screw thread 22, and power transmission short tube 23 is connected with outer drill bit 26 by screw thread 24.Bullet positioning supporting frame 13 lower ends of contracting are connected by screw thread 15 with beater mechanism at the bottom of the hole 21.Beater mechanism 21 is the external members that can buy on the market at the bottom of the hole, and its specifications and models can adopt gas impact machines such as DHD340A.Beater mechanism 21 lower ends are connected with interior drill bit 27 by screw thread 34 at the bottom of the hole, and interior drill bit 27 is by the interior outside keyway and outer drill bit 26 engagements of torsion pass mechanism 25 at the bottom of the hole.Torsion pass mechanism 25 is a pair of interior outside keyways at the bottom of the hole, drill bit 27 and outer drill bit 26 in it will be passed to from the moment of torsion of face of land rig with from the impact force of beater mechanism at the bottom of the hole 21.Spear-head 3 is fixing with recovery tube 5 by spearhead connecting pin 4, plays the effect that lifts recovery tube and inner tube assembly.The bullet positioning clamp 9 that contracts is fixed on bullet and contracts in the upper end central channel of positioning supporting frame 13 by playing bayonet lock 10, and the bullet positioning clamp 9 that contracts can shrink and open around playing bayonet lock 10.Recovery tube 5 covers on bullet the contract outside of positioning supporting frame 13 of positioning clamp 9 and bullet of contracting, there is cutting 31 at recovery tube 5 two ends, the bullet positioning clamp 9 that contracts can outwards open in 31 li of cuttings and bullet card frame central channel by means of tension spring 6, and it is indoor and play the lower end of fastening position joint to be positioned at the bullet card.Recovery tube 5 and the bullet positioning supporting frame 13 that contracts is connected by sliding pin 11 and fixes, recovery tube can slide on bullet contracts positioning supporting frame 13, the effect of beater mechanism 21 and interior drill bit 27 sliding pin 11 plays restriction recovery tube 5 distance of sliding and mentions the hole on bullet contracts positioning supporting frame 13 at the bottom of.When beginning to creep into, rig by drilling rod, play torsion pass mechanism 25 at the bottom of fastening position joint 2, bullet card chamber 8, slip female joint 18, slip male joint 20, power transmission short tube 23, the hole with the drawing of rig, turn round, pressure passes to outer drill bit 26 and interior drill bit 27.Meanwhile, in the hole, carry air from the face of land by air compressor machine, drilling rod internal diameter by institute's adapted, flow channels 29, circulation channel 30,32,12, water conservancy diversion sealing 8 and flowing hole 14, beater mechanism air inlet port 33 are transported to the inside of beater mechanism 21 at the bottom of the hole, and beater mechanism 21 begins impact work at the bottom of making the hole, because beater mechanism 21 is connected with interior drill bit 27 by screw thread at the bottom of the hole, so on the drill bit 27, interior drill bit 27 was passed to outer drill bit 26 by torsion pass mechanism 25 at the bottom of the hole with the part impact force again in impact force just was applied directly to.This just makes inside and outside drill bit apply impact grinding power in the rotating while to the stratum, further improves the crushing efficiency and the rate of penetration of rock.Creeping into certain depth need add stacks the time, only needing directly to add the drilling rod that makes up a joint and to continue to creep in the aperture.When creeping into desired depth, the aperture utilize the rope winch by drilling rod inner earlier with hand-hole under the salvaging mechanism in, salvaging mechanism can be caught spear-head 2 automatically in time at the bottom of the arrival hole, along with carrying on the salvaging mechanism, the cutting 31 of recovery tube 4 forces the bullet positioning clamp 9 that contracts to shrink, when it is retracted to when playing fastening position joint 2 internal diameters, continuation lifting along with salvaging mechanism, inner tube assembly partly will all be suggested outside the hole, and outer pipe assembly is left in the hole, promptly finish the drilling and forming hole purpose.This moment can be by drilling rod inside, play in the fastening position joint 2,8 inside, bullet card chamber and power transmission short tube 23 internal diameters inner and outer drill bit 26 are lowered to required ground tackle, explosive or other article.At last drilling rod in the hole and outer pipe assembly are proposed, promptly finish whole construction course.
Because this utility model adopts the effect that can play drilling rod and sleeve pipe simultaneously to single cover drilling pipe structure, moment of torsion that rig applies and pressure are directly delivered on the inside and outside drill bit, have improved impact rotating greatly and have crept into efficient.Inner tube assembly and outer pipe assembly adopt and play the fastening position, reclaim reliable.The operation that adds stacks and propose drilling rod is respectively than existing technology minimizing 50%, so operational sequence and non-cutting time reduce, labour intensity obviously reduces, and efficient improves greatly.
