Abstract

The invention relates to the technical field of petroleum drilling, and discloses an anti-falling PDC drill bit shackle device which comprises a shackle device body, a curled spring, a supporting frame connected to the shackle device body, a containing frame connected to the shackle device body, a force transmission shaft connected to the supporting frame, a control module, a force application piece and a net bag. The tail end of the force transmission shaft is connected with the control module, one end of the rope is fixed to the force transmission shaft, the other end of the rope is fixed to the force application piece, the force application piece is connected with the net bag, the two ends of the curled spring are connected with the containing frame and the force transmission shaft respectively, and the force transmission shaft can rotate. The problem that in the prior art, under the action of high torque, deformation possibly occurs, so that a drill bit slides out of a shackle device and falls into a well is solved.

Description

technical field [0001] The invention relates to the technical field of oil drilling, in particular to an anti-drop type PDC drill bit shackle. Background technique [0002] In the field of oil drilling, the shackle is an auxiliary tool used to connect or separate the drill bit from the drill pipe when the drill bit is going down the well. The shackle can replace the manual shackle to improve the efficiency and safety of making and breaking the shackle. Its external structure is square, with a notch corresponding to the shackle surface of the drill bit inside, and a handle for hoisting is welded on the top. When working, push the drill bit into the notch of the shackle and close the baffle, then put it into the square bushing on the turntable, and make up and break out by the torque of the drill pipe. But in the actual operation process, the shackle surface of the drill bit and the shackle surface of the shackle may be deformed under the action of higher torque, so that the ...
