The release of steel wire end rotary torsion when freely being rotated in decentralization, lifting and rotary course.Due to carrying in actual mechanical process
The upper and lower joint of lead device bears larger lifting force, and the lifting force causes revolution force of rolling friction greatly, and the power is delivered to steel wire rope and makes
Into steel wire rope excessive distortion and broken lot；The service life of steel wire rope is had a strong impact on.
The content of the invention
The present invention solves prior art problem and provides a kind of spacing by carrying out to elevator, prevents steel wire rope from rotating,
Reach the purpose of extension rotary drilling rig steel wire rope service life.
In order to solve the above-mentioned technical problem, it is a kind of extend the rotary drilling rig steel wire rope life-span elevator, including follow frame, on
Joint, body and lower contact, the top connection are connected realization linkage with lower contact by body, and the top connection connects with steel wire rope
Connect, lower contact is flexibly connected with drilling rod so that drilling rod can rotate in lower contact around axle center, it is described to follow frame to be provided with to upper
The spacing stopping means for preventing top connection from rotating of joint radial direction, when the stopping means is at the top of drilling rod is mentioned (i.e.：In interior drilling rod
When being fully retracted into) spacing to top connection come into force.
The stopping means is postive stop baffle, and the postive stop baffle is fixed on and follows on frame and postive stop baffle sets with vertical plane
There is an angle to form an inclined-plane, the top connection is provided with the inclined-plane with postive stop baffle slopes which match, when drilling rod mentions top,
The inclined-plane of top connection is spacing with the contact of incline plane of postive stop baffle.
The stopping means is spring pusher arrangement, and the spring pusher arrangement includes spring and push rod, the top connection
The stopper slot matched with push rod size is provided with, the push rod is arranged on by support and followed on frame, and by support pair
Push rod is radially spacing, and the spring housing on push rod, with push rod fix, another to be fixed on support, and drilling rod mentions top by one end
During portion, push rod joint motion and is installed on spacing in stopper slot upwardly by the effect of spring.
A kind of method for extending the rotary drilling rig steel wire rope life-span, installs stopping means, by stopping means on frame is followed
Limitation elevator top connection is axially rotated.
Stopping means uses baffle limiting mode or spring pusher arrangement limit method.
Due to using above-mentioned technical proposal, the present invention to break traditional thinking, by when drilling rod mentions top, passing through
Postive stop baffle or spring pusher arrangement carry out spacing, the top connection rotation of limitation elevator, so that steel wire rope to top connection
Do not rotate, and lower contact and drilling rod also can be flexible rotating, which eliminate the revolution force of rolling friction that lifting force is caused, and prevent
Only steel wire rope excessive distortion and broken lot, substantially increase the service life of steel wire rope.
