Description
Technical field
The utility model is related to the technical field of drilling tool stabilizer structure, particularly a kind of detachable with brill expansion
Eye stabilizer.
Background technology
Stabilizer is connected with drill bit, and the axial direction of stabilizer is evenly distributed with fin, and stabilizer is with flap apex arc
Face contacts with the borehole wall, reaches righting drilling tool and gauge effect.Utilizing drill bit in drilling process, the gauge ability of stabilizer is remote
More than bit gauge protection ability, if drill bit causes institute's bored borehole outside dimension less than stabilizer outside dimension because external diameter weares and teares, hold
Backing pressure is also easy to produce, or even situation about cannot creep into occurs, need to pull out of hole more bit change, increase drilling cost.And if boring and meeting easy undergauge
Stratum or mud property be not up to standard, causes borehole wall reduced diameter, situations such as easily cause bit freezing, bit bouncing, torque ripple, or even causes
Serious drilling failure, huge economic losses are brought to construction party.
It is evenly distributed with each fin of existing stabilizer in the gauge teeth of array, gauge teeth can effectively cut rock
Stone, reaches the purpose for expanding borehole size, however, after gauge teeth is chronically at working condition, gauge teeth wear damage is reduced
Its service life.Need to re-replace stabilizer after being damaged due to a gauge teeth, increase equipment investment cost.In addition gauge
Larger high temperature is produced during tooth rock cutting, gauge teeth rust is ultimately resulted in, causes rock cutting efficiency to decline.Therefore it is existing
Stabilizer is not promoted the use of.
Utility model content
The purpose of this utility model is the shortcoming for overcoming prior art, there is provided a kind of compact conformation, reduction gauge teeth table
Face temperature, quick-replaceable damaged gauge teeth, improve drilling efficiency, connection more firmly, reduce drilling cost it is detachable with
Bore reaming hole stabilizer.
The purpose of this utility model is achieved through the following technical solutions：A kind of detachable reaming while drilling stabilizer, it
Including stabilizer body and strip fin, uniformly there is multiple respectively on the cylinder of described stabilizer body and along its circumferencial direction
Strip fin, multiple skewed slots are provided with the outward flange of described strip fin, and inclined-plane and the stabilizer body axis of skewed slot are in
Angle is set, and is provided with wedge in skewed slot, and wedge side is vertical plane, is disposed with vertical plane and from top to bottom many
Individual gauge teeth, the inclined-plane of wedge is engaged with the inclined-plane of skewed slot, and the basal surface of strip fin is additionally provided with limiting stand, wedge
Lower surface contacted with limiting stand, driving lever is provided with the top of described wedge, runner, adjacent two are further opened with wedge
The delivery port of connection runner is provided between individual gauge teeth.
Four strip fins are distributed with the cylinder of described stabilizer body.
Described gauge teeth is higher by 0.3 ~ 0.4mm of vertical plane.
The spacing of described every two neighboring gauge teeth is equal.
The vertical setting of described runner.
Angle between the inclined-plane and stabilizer body axis of described skewed slot is 30 ~ 45.
The utility model has advantages below：（1）Runner, two neighboring guarantor are further opened with wedge of the present utility model
The delivery port of connection runner is provided between the tooth of footpath, to being passed through coolant in runner, coolant from after delivery port outflow with guarantor
Footpath tooth is in contact, so as to reduce gauge teeth surface temperature.（2）The inclined-plane of wedge of the present utility model matches with the inclined-plane of skewed slot
Close, the basal surface of strip fin is additionally provided with limiting stand, after one or more gauge teeth fatigue damages, radially pulls
Driving lever, wedge is extracted from skewed slot, the quick-replaceable of gauge teeth is completed by reinstalling new wedge, without inciting somebody to action
Whole stabilizer is changed, and reduces drilling cost.（3）Because inclined-plane coordinates, gauge teeth is interior more by skewed slot is embedded into after cutting force
Tightly, it is to avoid come off, with being connected firmly the characteristics of.

Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings, protection domain of the present utility model be not limited to
It is lower described：
As shown in Fig. 1 ~ 3, a kind of detachable reaming while drilling stabilizer, it includes stabilizer body 1 and strip fin 2,
Uniformly there are multiple strip fins 2 on the cylinder of described stabilizer body 1 and along its circumferencial direction respectively, stabilization in the present embodiment
It is distributed with four strip fins 2 on the cylinder of device body 1, multiple skewed slots 3 is provided with the outward flange of described strip fin 2,
The inclined-plane of skewed slot 3 is set with the axis of stabilizer body 1 in angle, inclined-plane and the stabilizer sheet of the skewed slot 3 described in the present embodiment
Angle between the axis of body 1 is that wedge 4 is provided with 42 °, skewed slot 3, and the side of wedge 4 is vertical plane, on vertical plane and by
On be down disposed with multiple gauge teeths 5, gauge teeth 5 is higher by 0.3 ~ 0.4mm of vertical plane, per between two neighboring gauge teeth 5
Away from equal, the inclined-plane of wedge 4 is engaged with the inclined-plane of skewed slot 3, i.e., wedge 4 is embedded in skewed slot 3, the bottom of strip fin 2
Surface is additionally provided with limiting stand 6, and the lower surface of wedge 4 is contacted with limiting stand 6, and limiting stand 6 serves the work of supports wedge block 4
With.Therefore when one or more 5 fatigue damages of gauge teeth after, driving lever 7 need to be radially pulled, by wedge 4 from oblique
Extracted in groove 3, the quick-replaceable of gauge teeth 5 is completed by reinstalling new wedge, without whole stabilizer is changed, drop
Low drilling cost.
The top of described wedge 4 is provided with and runner 8 is further opened with driving lever 7, wedge 4, the vertical setting of runner 8,
