Can be suitable for drilling process, the rough situation of well bore wall, avoids gauge teeth from damaging non-uniform situation, extends gauge
The service life of device.
When the drill body 1 with gauge device provided by the invention is started to work, during being contacted with the borehole wall,
The stressing conditions of the gauge device are：The gauge unit is under the action of horizontal force, the first gauge teeth 2 and the second gauge teeth
3 are parallel to each other, and both of which is hingedly pushed away perpendicular to the axial direction of drill body 1, the first gauge teeth 2 by head rod 5
Bar 4, since push rod 4 is parallel to the axial direction of drill body 1, the extruding that is subject to when the first gauge teeth 2 in horizontal direction
During power, in order to realize the extent of damage for reducing the first gauge teeth 2, the first gauge teeth 2 shrinks under external force, while promotes the
One connecting rod 5 rotates so that and the outside of the head rod 5 at the first hinge joint 8 is contradicted onto the cavity wall of the 4th cavity 704,
Slip is realized at the same time and promotes the second hinge joint 9 to rotate so that push rod 4 drives the 4th hinge joint 11 to move, while passes through second
Connecting rod 6, the 3rd hinge joint 10 release second gauge teeth 2 along the side wall of the 5th cavity 705, make the second gauge teeth 2 with
Well bore wall contact, it is achieved thereby that by the stress of the first gauge teeth 2 share to the second gauge teeth 3, the 4th cavity 704 side wall and
Head rod 5, is shared the stress of a gauge teeth to its excess-three by the gauge device in the present invention, reaches protection institute
The gauge function of gauge unit is stated, so as to extend the service life of gauge unit, is reduced due to the gauge on drill body 1
The number of drill body 1 is replaced caused by tooth excessive wear, drilling efficiency is improved, reduces drilling cost.
First gauge teeth, 2 and second gauge teeth 3 is using tungsten-carbide powder as matrix, makees binding agent through adding with cobalt powder
The hard alloy that pressure, sintering form；Deposition has one on the flank of tooth of first gauge teeth 2 and on the flank of tooth of the second gauge teeth 3
The ultrahard titanium carbide or titanium nitride of 5~7um of layer.After first gauge teeth 2, the second gauge teeth 3 have all been worn, it can pass through
First, second gauge teeth is inside contracted a part by push rod 4, so as to using Shooting Technique, pour again in the first cavity 701
One gauge teeth 2, pours the second gauge teeth 3 again in the second cavity 702, so as to extend the service life of drill body 1, reduces
The number of drill body 1 is replaced, improves drilling efficiency, saves cost.
