Aiming at the problem that vibration of existing drilling system, bouncing of drilling tool and de- pressure, the present invention proposes that inertial confinement induces drilling side
Method.The present invention utilizes the impact vibration response theory of rotor dynamics inertial load, a kind of inertial confinement that repeat is realized
Induce drilling method.The principle of the invention is to discharge the freedom degree constraint of rotor inertia constraint induction, the design of replacement system statics
Method matches independent inertial confinement circumferential direction change impacts vibratory response, alleviates the drilling body that drill bit creeps into the card that is hampered
Be wave motion response, stablize drilling system basic machining condition, realize continuous-stable drilling method, for drill deeply, deep hole
Processing and high-efficient cutting provide a kind of method of completely new inertial confinement induction drilling.
Compared with prior art, the present invention has the characteristics that 5:
1) it impacts stable and continuous: alleviating drill bit and be hampered shock motion, inhibit to eliminate the vibration of drill string system from source；It is hampered
Resistance is timely responded to brokenly, drilling is avoided to be interrupted, ensures that cutting is continuous；
Drill bit, which is hampered, generates the side knock wave of torsional shear, and is communicated up torsional pulse cross by inertia planet carrier 9
Wave, and resolve into three tunnels and be communicated up.First via shock wave decomposes Partial Shear shock wave by torsionspring 12, but by turning round
Turning the flexible of spring reduces the peak value buffering of shearing impact wave；Second tunnel and third road shock wave pass through respectively planetary gear 8 and
Sun gear 1 decomposes impulsive torque by transmission ratio, and wherein most impulsive torque is transmitted in inertia duplex outer gear ring 4, only small
Part torsional impact wave is transmitted on drilling rod alleviates shock motion significantly, it is suppressed that drill string system vibratory impulse in response to belt is come
Oscillating movement, reduce drill vibration.
Simultaneously when drilling starts bit cutting, before drill bit does not reach the cutting moment of torque, the torque that sun gear 1 inputs is first
It is stored in the form of potential energy in torsionspring 12.When drill bit reaches the cutting moment of torque, apparatus of the present invention and drill bit synchronous rotary
Drilling, drilling have just begun with progress.Once drill bit is hampered in drilling process, the inertia duplex outer gear ring 4 of synchronous rotation is relied on
Inertia discharges section store potential energy, and moment is added on drill bit, accordingly provides additional broken rock torque, while its velocity of rotation
It is corresponding to reduce.Additional broken rock torque and the size of deceleration provided by the present apparatus depend on the size being hampered, and be hampered big release energy
Amount is more, slows down big, vice versa.Energy after drill bit broken rock discharges suddenly, and drill bit can show rotation and accelerate to advance by leaps and bounds；Slow down simultaneously
Inertia duplex outer gear ring 4 also synchronous require to accelerate the original drilling velocity of rotation that follows up；It as a result is exactly the energy discharged after broken rock
Amount is redistributed, and drill bit acceleration, which is advanced by leaps and bounds, to be slowed down, and inertia duplex outer gear ring 4 is synchronous with coming up.The alternate stress that such drill bit is subject to
Reduce, complete the cutting circulation of a wheel shock response, the cycle period that drill bit continuously buffers is formed, and the item of continuous cutting is formed
Part.
2) durability guarantee: structure slows down the alternate stress that drill bit is subject to, and ensures drill bit fatigue life.
It is horizontal that rock cutting needs drill bit to undertake certain loading stress, but if the fluctuation of this loading stress is excessive,
Damage drill bit will be easier by fluctuating shock loading；If drill bit bit pressure and kinetic stability are good in continuous drilling, drill bit is cut
The fluctuation for cutting mean stress is small, that is, the stress ratio of alternation fluctuating load is small.The present invention by above-mentioned buffer shock-absorbing system,
Can effectively control the stress fluctuation amplitude of alternating load, the impact of cushioned drill bit inertial oscillation, reduce the broken resistance of drill bit advance by leaps and bounds with
And the impact velocity that is hampered, realize the durability guarantee of drilling life of bit.
3) hole quality guarantees: continuous and stable Drilling bore bit is not swung, and eye diameter is secure, the smooth rule of eyelet；
Just because of above-mentioned buffering and reason, drilling rod wave motion response is small and bit cutting is continuous, and drilling rod is not easy
The kinetic stability problem of brill is now put, drill bit only has the cutting movement of rotation, and the rare revolution motion for swinging drilling then creeps into hole
The amplification degree of eye diameter is just guaranteed.The drill bit movement track stable and continuous of cutting simultaneously, so drilling eyelet relative smooth rule
Then.
4) economy: without extra power demand, no displacement requirements do not flog a dead horse, low energy consumption；
Relative to both at home and abroad using fluid displacement come the patent of invention of assisted machining, such as the Tork Buster of Atlas
The technologies such as drilling tool and screw pump combined drilling are rushed with domestic torsion, necessarily will increase well head under same mud displacement
The consumption of mud plunger pump load bring energy consumption.Apparatus of the present invention are without fluid dynamic demand, also unlike Atlas Tork
Buster active attack rock is only to be cut after being hampered by dynamic response.Apparatus of the present invention do not consume fluid dynamic, also not blindly
The power of drill string conduction is consumed, then energy consumption reduces naturally.
5) novelty: conventional static design concept, the realization technology of applied dynamics design principle are broken through.
The design principle of apparatus of the present invention is the design concept from dynamics, is related to rotation, speed, vibration, punching
It hits, frequency response, advance by leaps and bounds and the concept of time such as sluggishness.Not only theory structure is peculiar, dynamic design method and bump vibration
Concept is also novel.
