Description
Technical field
The utility model is related to field of drill, more particularly to a kind of reaming inserted tooth hob drill bit with righting function.
Background technology
Anti- well rig technological principle is the motor belt motor hydrodynamic pressure motor by rig, fluid motor-driven tap, and profit
Drilling system is delivered torque to hydraulic power, the hobboing cutter on drilling rod and bit, guide hole drill bit or reaming bit is driven
In the presence of the pressure of the drill, pure rolling or micro sliding are done along bottom rock working face.The axial direction that main frame oil cylinder is produced simultaneously is drawn, pressure
Power, is acted on guide hole drill bit or reaming bit also by unit head, drilling rod, the hobboing cutter of guide hole drill bit is rolled under the pressure of the drill effect
It is dynamic, impact load is produced, hob teeth is produced impact, extruding and shear action, fractured rock to rock.The cutter head of anti-well rig
It is fixed on by bearing on drill main body.
Number of patent application discloses a kind of anti-well rig forward direction for CN200820211633.7 utility model patent and bored
Well reaming bit, the anti-well rig includes upper and lower central tube, bit body, broken rock cutter, bit body with positive reamer bit of bored well
The end of lower center tube is fixedly mounted on, bit body is pan type, and its circumference top edge, bottom and inclined-plane are respectively fixed with wear-resisting
Guide plate, drag twist and some broken rock cutters；The excessive ring flange on bit body top is fixed on lower center tube, and excessively flange
Mutually consolidated by the bottom plate under upper guiding assemblage after some balancing weights of support plate washer support mutual cooperation superposition above disk, afterwards
Mutually fixed by positioning baffle ring circle；And balancing weight outer circle wall has between convex platform and scrobicular ring, and scrobicular ring and balancing weight wall up and down
There is the hanger groove that section is " hanger " type.Because the drill bit uses said structure, positioning retainer ring, upper guiding are provided with its structure
Assembly, balancing weight, lower guiding wearing plate, drag twist, so as to serve the effect of monolithic stability, it is to avoid fall the weight such as brill, bit freezing
Big economic security accident；Also it can play borehole wall supporting in drilling simultaneously；There is the work of unloading of the positive drilling well of anti-well rig again
Make working face on the ground, also ensure that the personal safety of workmen.This structure of " funnel " type bit body, also causes broken
Rock slag along scalene cone from slipping slipping in cash hole to Drilling in advance, it is to avoid repeat broken, drilling efficiency can be improved；Bit body front end
Drag twist can prevent in drilling process the blocking for causing to slip cash hole due to bulk rock slag, ensure to slip cash hole it is smooth while
It may also function as the effect of guiding；Drill bit overall structure is simple, dismounting and convenient transportation, and can be larger in smaller working space Drilling
Diameter vertical shaft.The positive reamer bit of bored well of anti-well rig is improved in terms of Drilling pit shaft efficiency and economic benefit.
In reaming procedure, because well is larger, there is larger gap between drilling rod and bore hole inside wall, cause drilling rod inclined
The heart, so that there is deviation in the path of the drilling route of re-drill bit and former well.The centralizer connected on oil drill rocker only compares drilling rod
Larger with regard to that can play righting effect, and the well in raising boring field is very big, and conventional centralizer can not play righting effect,
Cause borehole path error larger.The problem of bit freezing being easily caused after centralizer is connected on some drilling rods.
