| description | The utility model discloses a device for connecting tensile pressure -torsion changes, including the top connection, the lower extreme detachably of top connection is connected with the lower clutch,and the circumference equipartition has a plurality of half first grooves on the outer wall of lower clutch, and the circumference equipartition has half groove of a plurality of seconds, every on theouter wall of top connection the back is connected at top connection and lower clutch in half first groove, becomes a keyway, every rather than half flute profile of second that corresponds respectively install the connection key in the keyway respectively. The utility model discloses device for connecting tensile pressure -torsion changes can realize the connection between each module among thetop drive device fast to have that the height bears the weight of, gao cheng turns round and the characteristic of high pressure -bearing, thus greatly reduced top drive device's the manufacturing degree of difficulty.
