The technical solution of the utility model realizes in the following manner:
This practical phenotype is mainly by top connection, joint ring, rubber ring, the pressure testing shear pin, seal receptacle, ball seat, upper pressing cap, brake pad, spring, centralizer body, adapter sleeve, the feather key pressure cap, feather key, cone, lock tube, slips, lock pin, central tube, disanchor shear pin and lower contact formed, it is characterized in that central tube is made as tubular, be provided with the top connection that is threaded in the upper end of central tube, be provided with seal receptacle in inside, central tube upper end, seal receptacle is provided with the ball seat that connects with the examination shear pin, be provided with six slot type centralizer bodies of symmetry in the upper periphery of central tube, 60 ° of angles, in centralizer body, be provided with helical spring, be pressed with arc brake pad at the spring top, the brake pad upper end is fixed by the upper pressing cap that is threaded with centralizer body, the brake pad lower end is fixed by the adapter sleeve that is threaded with centralizer body, be provided with 2 featherways of symmetry in the middle and lower part of central tube periphery, be provided with lock tube in the featherway periphery, be provided with the feather key that cooperates with featherway on the central tube on lock tube top, periphery at feather key is pressed with the feather key pressure cap that is threaded with lock tube, be with a downward cone of awl point in feather key pressure cap lower, outer perimeter, the cone upper periphery is connected with the adapter sleeve lower thread, be provided with the slips of 60 ° of the angles of six symmetries in the cone bottom, slips is sitting in the slip spider, slip spider is connected with lock tube by lock pin, is provided with disanchor a shear pin and a lower contact in the bottom of central tube.
The groove of centralizer body is made as trough with straight angle, is slidingly matched between trough with straight angle and the brake pad, is slidingly matched between centralizer body and the central tube.
Compared with the prior art the utility model has the following advantages:
1, owing to designed the ball-and-seat of pressure testing, can realize that completion tubular column suppresses experiment, reduce removing of a tubing string, time saving and energy saving, saved cost;
If 2 tubing string pressure testings are defective to be tripped out the anchor inspection and transfer once more, can reuse;
3, owing to designed the clutch rotation-preventing mechanism of forming by brake pad, spring and centralizer body, prevent to rotate midway and sit anchor;
4, sit anchor quick, as long as ground rotation tubing string, anchor is dangling grappling naturally, tubing string is pressure-bearing not, can not be out of shape;
5, the upper lifting pipe post is disanchored, is disanchored conveniently.
