Detailed Description
The invention is further illustrated by the following figures and examples in conjunction with the description:
the oil drill pipe slip comprises a rack, a fixing clip tile 1, a movable clip tile 2 and a driving mechanism 3, wherein the fixing clip tile is connected with the rack, the fixing clip tile and the movable clip tile are respectively in a semi-cylindrical shape, and one side edges of the fixing clip tile and the movable clip tile are hinged with each other; the driving mechanism 3 comprises a slide rail 31, a slide block 32, a first connecting rod 33, a triangular piece 34 and a second connecting rod 35, the slide rail is fixedly arranged on one side of the fixed clamping tile, the slide block is arranged on the slide rail in a sliding manner, one end of the first connecting rod is hinged with the slide block, and the other end of the first connecting rod is hinged with one corner of the triangular piece; one end of the second connecting rod is hinged with the rack, the other end of the second connecting rod is hinged with the other corner of the triangular piece, and the remaining corner of the triangular piece is hinged with the movable clamping tile; when the sliding block slides on the sliding rail, the movable clamping tile rotates relative to the hinged point of the movable clamping tile and the fixed clamping tile so as to enable the movable clamping tile and the fixed clamping tile to be mutually closed or separated, and when the movable clamping tile and the fixed clamping tile are mutually closed, the hinged point of the triangular piece and the movable clamping tile is positioned on the extension line of the second connecting rod.
The embodiment utilizes link mechanism to drive the activity card tile, and when the closed tight drilling rod that presss from both sides of activity card tile and fixing clip tile, link mechanism second connecting rod and triangle piece produced locking effect to the activity card tile by oneself, only need carry on spacingly to the slider with less effort this moment and can ensure that the slips can not loosen, has improved slips operating efficiency by a wide margin.
