Embodiment
It should be appreciated that specific embodiment described herein is not used to limit this only to explain the utility model
Utility model.
As shown in Figure 1 to Figure 3, the utility model provides a kind of sleeve rotating clutch, including top connection 1, rotating body
5th, torque sleeve 4 and lower contact 7.
Wherein, top connection 1, for being connected with upper tube string；Rotating body 5, is connected with top connection 1；Outside rotating body 5
Surface is provided with the first moment of torsion tooth 8；Torque sleeve 4, is set in the outside of rotating body 5, and with top connection 1 with can disconnecting members 2 enter
Row connection；The first end of torque sleeve 4 is provided with second be engaged with the first torsion sawtooth 8 and turns round sawtooth 9；Limiting part 3, is arranged on torsion
Between square set 4 and rotating body 5；Torque sleeve 4 is provided with the effect table top 10 matched with limiting part, and effect table top 10 is located at
The lower section of limiting part 3, makes the first torsion sawtooth 8 and second turn round sawtooth for being in contact when torque sleeve 4 is moved up with limiting part 3
9 completely disengage from；Lower contact 7, is connected with torque sleeve 4；Lower contact 7 is used to connect lower tube string.In the specific implementation, this can disconnect
Part 2 is shear pin；The limiting part 3 can be thrust bearing, and thrust bearing can be set close to the end face of top connection 1.
When the first moment of torsion tooth 8 on rotating body 5 is at a fully engaged with the second moment of torsion tooth 9 on torque sleeve 4 such as Fig. 1 institutes
Show, rotation torque can be transmitted.Because the sleeve rotating clutch that the utility model is provided is the middle part that is connected to whole tubing string
, when tubing string is in straight well section or smaller tripping in frictional resistance, sleeve rotating clutch is in extended state, now the first moment of torsion tooth
8 are intermeshed with the second moment of torsion tooth 9, and whole pipe string can be driven to rotate by well head, so as to further reduce tripping in frictional resistance.
When tubing string enters lower curved section, if tripping in frictional resistance not less than can disconnecting members 2 preset value；If this can disconnecting members 2
For shear pin, then the preset value is the shear force of the shear pin, and rotation torque is when within safe torque, the first moment of torsion tooth 8 and the
Two moment of torsion teeth 9 are still within engagement, can continue through rotation and reduce frictional resistance.When rotation torque exceedes safe torque value,
Then stop the rotation, push drilling tool, but frictional resistance is when exceeding shear pin shear force, can disconnecting members 2 disconnect, lower contact 7 with torque sleeve 4
Move, until the effect table top of torque sleeve 4 is contacted with limiting part 3, now the first moment of torsion tooth 8 and the second moment of torsion tooth 9 depart from such as Fig. 3
It is shown, be no longer able to transmit rotation torque, and bottom string friction produce upward active force, act on limiting part 3.
So the top connection of upper tube string and rotary clutch, rotating body can be driven to rotate by well head, and bottom tubing string is with
Joint, torque sleeve do not rotate.The sleeve pipe of clutch bottom can be thus protected, while rotary clutch upper tube can be passed through
Post reduces frictional resistance, so that bigger the pressure of the drill is applied on lower tube string, it is ensured that lower tube string can be lowered into projected depth.
In the present embodiment, rotating body 5 is cylindrical shape, and the first moment of torsion tooth 8 is evenly distributed on the outer surface of rotating body 5,
E.g. on the outer surface at the middle part of rotating body 5；The outer surface that first moment of torsion tooth 8 protrudes from rotating body 5 is set, and first
The root of moment of torsion tooth 8 has limiting stand terrace 12.In the specific implementation, the first moment of torsion tooth 8 can be rectangle moment of torsion tooth, now,
It is also rectangle moment of torsion tooth that meshed second, which turns round sawtooth 9,.
In another embodiment of the present utility model, the one end of rotating body 5 away from top connection 1 can be with the phase of lower contact 7
Contact, in order to effectively reduce rotation frictional resistance, can be provided with needle bearing 6 between lower contact 7 and rotating body 5.In order to protect
The sealing in pipe and postrotational sealing reliability are demonstrate,proved, sealing ring 11 can also be set between lower contact 7 and rotating body 5.
In the present embodiment, the outer surface of torque sleeve 4 is provided with screw thread, and the screw thread is located at the second top for turning round sawtooth 9, for even
Connect lower contact 7.
The sleeve rotating clutch that the utility model is provided, the outer surface of its rotating body 5 is machined with the first moment of torsion tooth 8,
Torque sleeve 4 is enclosed on outside rotating body 5 from upper end, and the outer surface of torque sleeve 4 is threaded, and flighting front end is machined with and first
The second moment of torsion tooth 9 that moment of torsion tooth 8 is engaged.Top connection 1 can be connected through a screw thread with rotating body 5, and torque sleeve 4 can pass through
Shear pin is fixed with top connection 1, and thrust bearing 3 is provided between torque sleeve 4 and rotating body.Lower contact 7 is from the lower end of rotating body 5
Be inserted in, and with the threaded connection on torque sleeve 4, the bottom of lower contact 7 connection lower tube string, and by torque sleeve 4 by underlying load
It is delivered on rotating body 5.Needle bearing 6 is installed between lower contact 7 and rotating body 5, rotation so can be effectively reduced
Frictional resistance.And sealing ring 11 is installed between lower contact and rotating body, it is ensured that sealing and postrotational sealing in pipe can
By property.
The sleeve rotating clutch that the utility model is provided, when it is in extended state, the on torque sleeve and body
One moment of torsion tooth and the intermeshing of the second moment of torsion tooth, can drive whole tubing string to rotate by well head, and at pipe rotary clutch
When compressive state, the first moment of torsion tooth and the second moment of torsion tooth are mutually disengaged, so as to realize that pipe rotary clutch top tubing string can revolve
Turn, and the purpose that bottom tubing string can not rotate.The utility model is applied to during pipe string tripping in, can when rotational resistance is little
By rotating whole pipe string, reduce the tripping in frictional resistance of pipe string, and whole pipe string rotations can not be realized when bottom rotation torque is larger
When turning, the pressure of the drill of lower tube string can be delivered to by the rotation increase of upper tube string, pipe string is improved in high angle hole, big displacement
Tripping in success rate in well and horizontal well.
