Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
A kind of basement rock triple pipe core bit that the utility model relates to, comprise outer pipe assembly and inner tube assembly, described outer pipe assembly comprises the outer tube joint 1, outer tube 10, reamer 14 and the drill bit 17 that connect successively, described inner tube assembly comprises the interior tube core axle 2, inner pipe joint 18, interior pipe 11, interior pipe pipe nipple 13, interior pipe clamp spring 16 and the clip spring seat 15 that connect successively, and outer pipe assembly is connected with tube core axle 2 in inner tube assembly by outer tube joint 1.
Inner pipe joint 18 is coated at interior tube core axle 2, some bearings and bearing support 20 is provided therebetween, is provided with spacer sleeve 6 between bearing.Be provided with hold-down screw 8 between inner pipe joint 18 afterbody and interior tube core axle 2 afterbody, hold-down screw 8 stretches into the endoporus of interior tube core axle 2, and hold-down screw 8 head is provided with steel ball 19 and spring 21.Between interior tube core axle 2 and inner pipe joint 18 head, bearing arranged outside has sealing ring 22, and sealing ring 22 overcoat has gland 4.Between interior tube core axle 2 and inner pipe joint 18 head, sealing ring 22 arranged outside has inner pipe joint jump ring 3.Interior tube core axle 2 external edge of head is provided with dust cap 23.
Be provided with bushing pipe 12 in described inner tube assembly, between bushing pipe 12 end and inner pipe joint 18, be provided with bushing pipe piston 9.Bushing pipe 12 is made up of two parts half bushing pipe separated along centre position radial direction.
Bearing between inner pipe joint 18 and interior tube core axle 2 comprises the deep groove ball bearing 5 at two ends and middle axial ball bearing 7.Deep groove ball bearing 5 mainly rotary steering effect, constraint inner pipe joint 18 rotates along interior tube core axle 2, does not produce and radially wobbles.This cover drilling tool inner and outer pipes gap less (gap 2mm), adopts deep groove ball bearing structure can ensure that interior pipe can well lead, reliable operation.From interior pipe 11 thrust upwards when axial ball bearing 7 mainly bears work.When drilling tool creeps in hole, core enters interior pipe 11 from down, and internal pipe 11 has a thrust upwards, and particularly when there is core blocking in hole, drilling tool axially loaded can turn to inner tube assembly by outer tube 10, makes interior pipe produce larger lifting force.Reliability and application life that axial ball bearing 7 can increase rotating mechanism work are set.Above-mentioned to lifting force transfer route be dish → interior tube core axle 2 → outer tube joint 1 on interior pipe 11 → inner pipe joint 18 → bearing 5 outer ring lower wall → bearing support 20 → bearing 7 → spacer sleeve 6 → bearing 5 inner ring.
Operating principle:
Outer tube joint 1 drives the rotation gram of outer tube 10, reamer 14 and drill bit 17 to get rock; column core enters inner tube assembly in drill bit 17 ring-type labial surface; inner tube assembly can keep relative static conditions with core under static core resistance, and its effect is that protection core is not subject to washing away of flushing liquor and minimizing drilling tool of trying one's best rotates the destruction of causing core.In interior pipe 11, be placed with one be divided into upper and lower two-part special stainless steel bushing pipe 12 along centre position radial direction.Creep into after round trip terminates, gently carry and rotary tools, the interior pipe clamp spring 16 of interior pipe lower end can embrace the disconnected core of card, after carrying brill, dismantles drill bit 17, reamer 14, extracts bushing pipe 12 out, open the pipe that narrows, just can observe whole complete core.
Drilling fluid enters inner and outer pipes gap through outer tube joint 1 after drill pipe bore flows down, and at the bottom of drill bit water hole and tank access aperture, then return to ground through outer tube 10 and hole wall, complete the direct circulation of drilling fluid.Interior pipe flushing liquor enters pipe 11 top in Shi Kejing at rock core and directly gets back between outer tube 10 and hole wall and get rid of.Drilling fluid does not enter interior pipe 11 and washes away core, effectively can improve core recovery.Regulate cooperation and the drill bit tank form of clip spring seat 15 and drill bit 17, also can realize local reverse-circulation in hole, the flushing liquor namely between inner and outer pipes is under the effect of pump pressure, and a part of flushing liquor upwards returns through duct, interior pipe 11 top along in interior pipe 11 simultaneously.The advantage of this local reverse-circulation function to improve core recovery percentage, is beneficial to the hole bed rock heart and reclaims, reduce the generation of core jam problem.
The structure that the utility model relates to has following characteristics:
1) drill bit 17 drives lower gram to get rock at outer tube 10; it is main stressed member; interior pipe 11 and bushing pipe 12 are arranged on rotating ring (comprise bearing etc. and rotate auxiliary spare part); interior pipe 11 non rotating when creeping into operation; play the effect of protection rock core; creep into after round trip terminates, from interior pipe 11, extract bushing pipe 12 out, the core taked just can the together taking-up of safety.
2) adjusted by field trial and internal pipe 11 gap of debugging and interior pipe 11 appearance and size, the thinner and inner and outer pipes gap smaller of bushing pipe 12, effectively reduces the thickness of drill bit 17 ring-type labial surface.This drill bit 17 internal diameter is ∮ 80mm, can realize the function of single action triple pipe drilling tool, and drill bit 17 wall thickness to compare traditional single rotary double core barrel less, hard-rock boring efficiency significantly improves.
3) traditional ∮ 110mm two-tube drilling tool inner and outer pipes annular gap is 5mm, and the internal pipe appearance and size of basement rock triple pipe core bit of exploitation adjusts, and inner and outer pipes gap is adjusted to 2mm.
4) in tradition, pipe drilling tool generally adopts ∮ 89mm tubing, wall thickness 4mm.The internal pipe appearance and size of basement rock triple pipe core bit of exploitation adjusts, and adopts ∮ 95mm tubing, wall thickness 3mm.
Content of the present utility model is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading the utility model manual to any equivalence that technical solutions of the utility model are taked, is claim of the present utility model and contains.
