Description
Technical field
It is specifically a kind of driven with whole down-hole hammer and transmission dress the present invention relates to a kind of down-hole hammer Special working device
The rotary drilling rig put, belongs to rotary drilling rig down-hole hammer driving structure technical field.
Background technology
Catalase, which is principally fallen into, in rotary drilling rig construction shears into rock, the condition crushed according to rock shearing, churning driven
Machine is to realize smoothly to enter rock and must possess high pulling torque, the high rigidity of the big plus-pressure that effectively transmits and drilling tool pick with it is wear-resisting
Three big factors of property.However, due to the limitation of rear two factor, rotary drilling rig efficiency of construction under hard rock operating mode is extremely low；Moreover,
Because stratum is fluctuated greatly to the reaction force of equipment, and peak value is high, and the structural member fatigability infringement to equipment is larger.
Drilling Technology of Airdriven DTH Hammer is a kind of more drilling technology of domestic and international application, is also air drilling technology broken
An important breakthrough in rock method, it utilizes the energy production of compressed air mainly using compressed air as dynamic medium
The bottom hole power equipment of repetitive shocks, while compressed air can double as hole flushing medium.Under usual condition, pneumatic down-hole hammer
Directly it is connected with hard alloy columnar teeth drill bit to impact mode detritus, low speed turns round total cost management of not coring.If by aeratic hidden hole
Hammer is supported the use with rotary drilling rig, can not only increase substantially drilling efficiency but also hole quality is preferable, construction cost is low,
It is suitable for Rock penetrating more than medium hardness, particularly in competent bed drilling.
Existing pneumatic down-hole hammer point direct circulation down-hole hammer and reverse circulation down-the-hole hammer, generally, direct circulation down-hole hammer
Using direct circulation construction technology, reacting cycle hammer uses reverse circulation construction technique.Direct circulation construction technology, which refers to be turned round by rig, to be filled
Drive drilling rod and the broken ground of drill bit revolution cutting are put, then mud is input into from slush pump toward drilling rod, mud rises along drilling rod hole wall,
Overflowed from aperture and flow into mud pit, circulatory pool is returned through precipitation.Reverse circulation construction technique, which refers to be driven by rig slewing equipment, to be bored
Bar and the broken ground of drill bit revolution cutting, are then bored using the measures such as pumping, gaslift, injection suction circulation slurry coat method, entrainment
Slag suctions out the forming hole method outside hole from drilling rod inner chamber.
When rotary drilling rig and down-hole hammer are used cooperatively, because triple channel structure hardly possible is designed, and in the market reacting cycle down-the-hole
Hammer aperture into shape smaller, most 0.3 meter or so of great talent, and direct circulation down-hole hammer diameter maximum can be to 2 meters, therefore reverse circulation down-the-hole hammer can not be fitted
Rotary digging construction requirement is answered, only direct circulation down-hole hammer can be used cooperatively with rotary drilling rig.But enter according to direct circulation construction technology
Row construction, is to prevent collapse hole during construction, it is necessary to sets full casing sleeve pipe follow-up construction, so not only increases cost, and arranged
Slag does not allow easily collecting, and environmental pollution is larger.Direct circulation construction technology institute can be solved by carrying out deslagging using reverse circulation construction technique
The problem of bringing, but how construct large aperture when realized with direct circulation down-hole hammer reacting cycle construction be pile foundation industry always
The difficult point not broken through.
In addition, traditional pneumatic down-hole hammer device, which is drilling rod and tap, is coupled with unit head upper and lower side, by unit head
Transfer port and investigation hole on drilling rod, tap is driven to be transformed into by unit head in drilling rod.Though this structure can also realize rotary digging
Rig is used cooperatively with pneumatic down-hole hammer, but unit head changes larger, it is impossible to very easily realize common rotary digging and aeratic hidden hole
Hammer the switching between rotary digging into shape.
