Abstract
Forced wire line coring drilling tool, it relates to a geology rock core probing utensil, comprises outer tube assembly and the two major subassemblies of inner tube assembly, outer tube assembly top -down is connected gradually by bullet card pressure head, bullet card room, enlarger, sealing chamber, spline housing, integral key shaft, outer coupling, outer tube and diamond bit and forms, and inner tube assembly top -down transfers long device, seals up guiding device, the impacter that surges, holds and hit joint, nozzle stub and rock core container and form by dragging for lance device, location linkage, buffering. The utility model discloses when being arranged in probing construction to creep into the fault crushed zone, can realize pressing coring and rotary drilling hocket, wearing and tearing and the flush fluid of rock core is to the erodeing of rock core when avoiding the drilling tool gyration, and core recovery higher and reached and drills requirements for quality.
Description
Technical field
The utility model relates to a kind of geological core drilling utensil, particularly relates to a kind of cord coring drill.
Background technology
In complete or chunky shape rock, use conventional cord coring drill to carry out drilling operation, core recovery percentage can reach probing quality requirement, but in loose earthy, be easily worn, use conventional cord coring drill to carry out drilling operation in the fault belt that easily washed away by liquid stream, core recovery percentage is lower or do not take rock core and do not reach probing quality requirement, if fault belt is ore bed, then do not reach the object verifying ore reserve.
Utility model content
The utility model provides a kind of cord coring drill, to solve the problem in above-mentioned background technology.
The technical solution adopted in the utility model is: the utility model is made up of outer pipe assembly and the large assembly of inner tube assembly two; Outer pipe assembly is connected in sequence by bullet card pressure head, bullet card room, reamer, closed chamber, spline housing, splined shaft, outer tube joint, outer tube and diamond bit from top to bottom, inner tube assembly from top to bottom by dragging for lance device, location suspension arrangement, buffering adjust growth device, sealing guide device, hydraulic impacter, hold and hit joint, short tube and rock core container and form.
Described fishing device forms by dragging for spearhead, spearhead seat and elastic cylindrical pin.
Described location suspension arrangement forms by playing card holder, bullet card, elastic cylindrical pin, cone bar, spring, spring base and collar.
Described buffering adjusts growth device to be made up of pull bar, reversal of the natural order of things joint and spring.
Described sealing guide device is made up of rise sealing ring and lower drain joint of upper drain joint, elastic cylindrical pin, pressure.
Described rock core container by inner pipe joint, steel ball, interior pipe, the pipe that narrows, block spring abutment and block spring and form.
When the utility model is used to creep into fault belt in drilling operation, can realize pressure coring and rotary drilling hockets, the wearing and tearing of rock core and flushing liquor washing away rock core when avoiding drilling tool to turn round, core recovery percentage is higher and reach probing quality requirement.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
In accompanying drawing: 1-bullet card pressure head; 2-drags for spearhead; 3-recovery tube; 4-elastic cylindrical pin; 5-spearhead seat; 6-elastic cylindrical pin; 7-spring base; 8-collar; 9-spring; 10-bullet card holder; 11-bores bar; 12-bullet card; 13-bullet card room; 14-elastic cylindrical pin; 15-pull bar; 16-reamer; 17-hangs upside down joint; 18-spring; 19-closed chamber; The upper drain joint of 20-; 21-elastic cylindrical pin; 22-presses the sealing ring that rises; Drain joint under 23-; 24-impactor; 25-spline housing; 26-holds and hits joint; 27-splined shaft; 28-short tube; 29-outer tube joint; 30-outer tube; 31-steel ball; 32-inner pipe joint; 33-narrows pipe; Pipe in 34-; 35-blocks spring abutment; 36-diamond bit; 37-blocks spring
Detailed description of the invention
When carrying out geological core drilling construction, when creeping into the core recovery percentage to fault belt with conventional cord coring drill and not reaching probing quality requirement, stopping creeping into, the drilling tool in boring is all mentioned on ground.Afterwards by under outer pipe assembly of the present utility model and the rope coring drill pipe that links together with it to the position at the bottom of access hole in boring, require diamond bit not at the bottom of contact hole, subsequently a certain amount of flushing liquor is pumped in the rope coring drill pipe in boring, liquid level in drilling rod is close to termination of pumping during ground, use winch again, inner tube assembly is mentioned and is put into the rope coring drill pipe of boring by wire rope and fisher, allow its free releasing, inner tube assembly drops to after in outer pipe assembly, the kelly be positioned on rig is docked with the drilling rod in hole, clamping device clamping kelly subsequently on rig, weigh, the value of pressurization or decompression is set, to ensure that the pressure being added in inner tube assembly is not more than 5kN, after aforesaid operations completes, the feed mechanism of rig is used to impel a whole set of drilling tool descending, inner tube assembly is allowed slowly to be pressed in fault belt, after inner tube assembly enters and reaches 600mm in zone of fracture, the base of spline housing contacts with the outer step of splined shaft and stops and is pressed into, so in time, stops being pressed into, kelly is dismantled and moves apart aperture, with winch, fisher hooks and drags for spearhead by wire rope bottom drilling rod is transferred to, inner tube assembly is mentioned ground, the pipe that narrows in taking out in pipe, rock core is placed in core box, again kelly is docked with the drilling rod in hole, start slush pump, flushing liquor is sent in hole, rotary drilling is carried out after at the bottom of liquid to be rinsed to hole, stop after drilling depth reaches 600mm creeping into and closing down slush pump, again kelly dismantled and move apart aperture, delivering in the drilling rod of inner tube assembly in boring, carry out the pressure coring of next round trip and creep into.When inner tube assembly be pressed into do not reach 600mm in zone of fracture and be hampered can not continue descending time, start slush pump, flushing liquor is sent in hole, impel impactor work, while impactor produces percussion, less pressure is imposed to inner tube assembly descending by its continuation, if still can not be descending, then stop pumping flushing liquor, on carry inner tube assembly, terminate forced coring operation, above to carry in hole a whole set of drilling tool to ground.
