Butut direction determine.
The utility model is further described below with reference to examples and drawings:
As shown in attached drawing 1,2,3, which includes sleeve 1 and fin 2, in the outer lateral edge of sleeve 1
At least three pieces fin 2 is distributed in circumference tilt, and the inclined direction of all fins 2 is consistent, and the outer end face of all fins 2 is located at same
On one reference cylindrical surface 3, and it is described coaxial referring to cylindrical surface 3 and sleeve 1, fin 2 is fixed together with sleeve 1, all fins 2
Left and right two on the outside of be equipped with the chamfering 4 of smooth transition, the left and right ends of fin 2 are concordant with the left and right ends of sleeve 1 respectively.
When in use, the utility model and accident treatment tool can be provided commonly for underground work, in normal operation, wing
Piece 2 has certain rigidity, can be adjacent to drilling tool inner wall when being not affected by strength and squeezing, and eliminates drilling tool to effectively absorb
Various complicated vibrations, play the role of righting between two parties, protect instrument and improve measurement accuracy；When needing this reality during salvaging
When with the novel path hydrophthalmia for passing through accident treatment tool etc., one end of the utility model can be against path by external drive
The end of hydrophthalmia, is then gradually increased stress, since fin 2 is tablet, and forms slanted angle between sleeve 1, thus
With certain elasticity, therefore, fin 2 will generate deformation under the guiding function of chamfering 4 and the squeezing action of external force, and
It is drawn close to 1 outer wall of sleeve, the maximum outside diameter of the utility model will be gradually decrease to that the path of accident treatment tool can be against at this time
Hydrophthalmia inner wall passes through, and after the utility model enters big hydrophthalmia drilling tool by path hydrophthalmia, fin 2, which can be sprung back, is reset to reply original
Shape can be close to drilling tool inner wall at this time, the various complicated vibrations for eliminating drilling tool can effectively be absorbed in normal drilling, to rise
It is placed in the middle to righting, it protects instrument and improves measurement accuracy.The utility model is designed reasonably is skillfully constructed, by by 2 edge of fin
Circumference tilt is distributed in 1 outside of sleeve, can be allowed to have angle between sleeve 1, convenient for fin 2 close to sleeve 1, and reduce this reality
With novel maximum outside diameter, path hydrophthalmia can be passed through, meet the utility model and accident treatment tool in deep-well
Or/and the synchronization job in Holes of Complicated Wells, the safety and rate of penetration of its operation are improved, and the also absorbable elimination under conventional operating condition
The various complicated vibrations of drilling tool, play the role of righting between two parties, protect instrument and improve measurement accuracy；Outside the left and right of fin 2 two
Side is equipped with chamfering 4 and can import convenient for the utility model from any direction of path hydrophthalmia, and chamfering 4 can make wing in smooth transition
Piece 2 gradually generates deformation, more convenient laborsaving, and can reduce obstruction, makes the left and right ends of fin 2 left and right with sleeve 1 respectively
Both ends of the surface are concordant, can avoid generating step and bent angle between the two, it is ensured that without card resistance when the utility model passes through path hydrophthalmia, into
One step shortened through the time, improves through efficiency, has the characteristics that safe, laborsaving, easy, efficient.
Above-mentioned foldable type wireless centering device with drilling can be made further optimization and/or improvements according to actual needs:
As shown in attached drawing 1,2,3, it is uniformly distributed at least three pieces fin 2 along the circumference on the outside of sleeve 1.Keep fin 2 circumferentially equal
Cloth can be such that it is more uniformly stressed, consequently facilitating prolonging its service life.
As shown in attached drawing 1,2,3, the lateral surface and 1 lateral surface of sleeve of fin 2 are tangent.Thus can convenient for fin 2 positioning and
Processing, while may make and form slanted angle between 1 lateral surface of medial surface and sleeve of fin 2, and the slanted angle is sharp
Thus angle can be generated close to sleeve 1 convenient for fin 2 after by external force, to reduce the maximum outside diameter of the utility model.
As shown in attached drawing 1,2,3, the diameter referring to cylindrical surface 3 is between 1.5 times to 2.5 times of 1 outer diameter of sleeve.Thus may be used
Ensure fin 2 while intensity meets centralizing function, deformation is able to satisfy the duty requirements by path hydrophthalmia, and in deformation
Resilient afterwards.
It at the point of contact of its end lateral surface and sleeve 1 is original with the fin 2 of 4 place end of chamfering as shown in attached drawing 1,2,3
The direction that fin 2 flexes outward from sleeve 1 is set as x-axis by point, and 2 lateral surface of fin and the line at the point of contact of sleeve 1 are set as
Y-axis, the formula of the curvilinear coordinate of chamfering 4 are y=0.1 × (x-12)9/5.Thus it can make chamfering 4 that there is good guide effect,
Enable fin 2 it is whole without card resistance close to sleeve 1, to reduce the maximum outside diameter of the utility model.
