Drilling tool includes drilling rod 24, pipe joint 25, basket 26, straight coupling 27, jump ring 28 and the drill bit 29 being coaxially disposed. Using the drilling direction of drill bit 29 before, the rear end of drilling rod 24 and mandrel 19 are threadedly coupled, and the front end of drilling rod 24 passes through pipe joint 25 and rock core The rear end of pipe 26 is threadedly coupled, and the front end of core barrel 26 is threadedly coupled by straight coupling 27 and drill bit 29.Drill bit 29 is by rear end Drilling bit steel body 32 and the diamond matrix of front end 33 are through hot-forming integral structure, the rear end inwall of drilling bit steel body 32 and straight-through The nose threads of joint 27 connect, and front inner wall is provided with the rounding conical surface 31, and the minimum diameter of the rounding conical surface 31 is more than Buddha's warrior attendant lithopedion The internal diameter of body 33, maximum inner diameter are the inwall aperture of drilling bit steel body 32.Jump ring 28 is the inverted cone bullet consistent with the taper of the rounding conical surface 31 Property tubular structure, side wall is provided with axially open, and it is arranged in drilling bit steel body 32, minimum outer diameter of the jump ring 28 under squeezed state More than the minimum diameter of the first rounding conical surface 31, and the maximum outside diameter under distending state is less than the inwall aperture of drilling bit steel body 32, The inwall of jump ring 28 is band tooth circular conical surface, and the minimum diameter under squeezed state is slightly less than the internal diameter of diamond matrix 33.It is straight-through to connect First 27 front end is provided with inside annular boss 30, and the internal diameter of annular boss 30 is more than the internal diameter of diamond matrix 33 and existed less than jump ring 28 Maximum outside diameter under squeezed state.
In the application, the squeezed state of jump ring 28 refers to the free state of 28 non-stress of jump ring, the distending state of jump ring 28 Refer to the state that core passes through jump ring 28 outward to strut.From figure 5 it can be seen that the scope of activities of jump ring 28 is limited in Between annular boss 30 and the rounding conical surface 31, before not creeping into, jump ring 28 can be up and down therebetween and rotated.Work as brill First 29 when starting to pierce, and because the internal diameter of diamond matrix 33 is more than the internal diameter of jump ring 28, core touches the front end of jump ring 28 first Interior starting taper, jump ring 28 is pushed up, when jump ring 28 contradict arrive annular boss 30 when, core will be squeezed into jump ring 28 In, now jump ring 28 is in distending state, because maximum outside diameter of the jump ring 28 under distending state is less than the inwall of drilling bit steel body 32 Aperture, gap is still kept between jump ring 28 and drilling bit steel body 27, so as to which in whole drilling process, jump ring 28 will not rotate, The pivoting friction with drilling bit steel body 27 can be reduced, while only exists and slides up and down between jump ring 28 and core, is also reduced to rock The abrasion of wicking surface.After drilling terminates, when being lifted up drilling tool, jump ring 28 will move because of the frictional force with core toward the rounding conical surface 31 Dynamic, under the extruding of the rounding conical surface 31, diminish internal-and external diameter, reaches the state of clamping core, now somewhat rotation drilling tool again, rock core It will be blocked by jump ring 28 disconnected, because core is blocked by jump ring 28, and jump ring 28 can not be deviate from from drilling bit steel body 27, so that Bore, coring once-through operation can be completed.
Auxiliary, which carries drill rod mechanism, includes winch 34, steel wire rope 35,36, two pulleys 37 of pulley bracket and elevator 41, twists Car 34 is arranged on the left side of the upper surface of base 1, and pulley bracket 36 is arranged on the top of mast 2, is symmetrical set, pulley 37 passes through Bearing pin 38 is separately mounted to the left and right ends of pulley bracket 36, and one end of steel wire rope 35 and winch 34 connect, and the other end bypasses respectively Two pulleys 37 tangle elevator, when needing to be lifted drilling rod 24, make hydraulic motor 12 and unit head 13 whole by bearing support 4 Device is got out of the way, and drilling rod 24 is directly connected to elevator 41, rotates winch 34, and steel wire rope 35 drives elevator 40 and drilling rod 24, from And reach and put forward brill purpose, use prior art as the concrete structure of elevator 41, and with the connected mode of drilling rod 24.Separately Outside, the top of mast 2 is additionally provided with hole for hoist 39, convenient that whole device is transferred into seabed from cargo ship.
Above-described embodiment is in the art the purpose is to be to allow simply to illustrate that the technical concepts and features of the present invention Those of ordinary skill can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all It is the equivalent change or modification made according to the essence of present invention, should all covers within the scope of the present invention.
