Description
Technical field
It has invented a kind of drilled suitable for cranny development rock mass, routine and easily stratum, the coal mine gob overlying of collapse hole has occurred
Destroy the drill bit of the drilling operation of rock stratum.
Background technology
From drilling engineering angle, definition of the Luoping Asia academician to broken formation:Originally broken by tectonic stress effect
Stratum (completely broken, a large amount of cracks ...) and broken stratum is generated under burden pressure effect after wellbore is formed.It should
The distinguishing feature on class stratum is:Broken imperfect, cementing properties is poor, and fracture development is often accompanied by strata pressure；These features determine
Broken formation wall stability is poor, the complicated drilling accident such as hole wall collapse, chip off-falling, bit freezing often occurs.
The approach that such stratum hole wall is stablized at present：1. increasing the bond that broken formation is crushed between sillar；2. can
Quick wall building avoids a large amount of flushing liquors from entering among broken formation；It is the core that broken formation hole wall is stablized 3. blocking crack
The heart.4. " the serious broken formation for phenomenon of caving in need to moderately improve the density or viscosity of flushing liquor for chip off-falling.5. with caution
Construction, careful operation avoid causing the unstable of hole wall due to operation error.
The type of drill bit shapes drilling, and penetration rate drilling quality plays the role of key.For broken formation, crack
Rock mass, coal mine gob overlying destruction rock stratum, the drilling smooth construction of drilling project are developed, drilling forming quality is proposed more
High request.Such stratigraphical drilling is easier to cause collapse hole, bit freezing, is smoothed out so that influencing probing, or even the work that can not drill
Industry.In order to solve such stratigraphical drilling, engineers and technicians propose various drill bits and drilling tool, such as patent (application number：
201410028994.8) disclose a kind of drill bit for coal mine underground soft coal seam gas extraction drill hole protection, patent (application number：
201210186208.8) disclose a kind of coal mine gas drainage holes drill bit；Patent (application number：201310370838.5) disclose
A kind of three axis blender drill bits being suitable for penetrate through garden gravel bed soil property；Patent (application number：201410202356.3) disclose one
Kind intelligence is double to expand wing reaming hole drill bit of pile machine.
The effect that these patents and technology have achieved in the probing of all kinds of broken formations, but rock stratum is moved caused by exploitation
Dynamic and Overburden Rock Failure has its own rule, and the present invention is a kind of to be suitable for cranny development rock mass, conventional probing easily collapse hole occurs
The drill bit of the drilling operation of rock stratum is destroyed on stratum, coal mine gob overlying.
Invention content
The purpose of the present invention is to provide a kind of drill bits suitable for broken formation probing, to achieve the above object, this hair
Bright technical solution is：
It is connected to form an entirety by fixed disk between drill bit outer barrel and spring, between the top connection and drilling rod of spring
Using threaded connection, using being threadedly coupled between the lower contact and upright bar of spring, connected using bolt between upright bar and drill bit cutterhead
It connects, is connected using bolt between upright bar and drill bit cutterhead connection ring.
Drilling rod and drill bit drop in drilling, apply pressure from drilling rod to drill bit, and pressure passes to upright bar by spring, stands
Bar applies pressure to drill bit cutterhead top again, and bit wing armor is rotated around fixing axle, and drill bit cutterhead lower part reaches outside casing.
The groove of drill bit outer barrel and the convex cone of drill bit cutterhead and drilling rod sleeve concave-convex joint are engaged, and drilling rod rotation, which is transmitted, to be turned round
Square gives drill bit outer barrel, drill bit outer barrel that rotation torque is transferred to drill bit cutterhead broken rock, and with drill bit cutterhead broken rock, borehole casing is downward
Extend；By flowing into mud in drilling rod, mud is discharged between drilling rod and borehole casing and outside borehole casing, it will be with rock by mud cycle
It considers to be worth doing to ground.
Probing terminates drilling rod and lifts, and drill bit spring contraction pulls upright bar, bit wing disc spins to be contracted in borehole casing, bores
Hole sleeve prevents drilling from collapse hole occur.
The beneficial technical effect of the present invention lies in：Ensure that broken formation can be drilled normally and smooth pore-forming.
The drill bit of the present invention is suitable for following types of formations：1. cranny development rock mass；2. easily there is collapse hole in conventional probing
Stratum；3. coal mine gob overlying destroys rock stratum.
