Abstract

The invention relates to a clamping device for fixing. The clamping device comprises a clamping ring, and the clamping ring comprises two symmetrically-arranged clamping ring bodies; a hinge is arranged at the closed ends of the clamping ring bodies; fixed plates matched with a screw rod and screw caps are arranged at the opened end of the clamping ring bodies; a plurality of grooves are formed in the clamping ring bodies, and reset mechanisms are arranged in the grooves; clamping blocks are arranged at the upper ends of the reset mechanisms; clamping surfaces are arranged on the clamping blocks, and are inwards sunk to form arc surfaces; and the radian of the arc surfaces is matched with a drill rod. According to the clamping device, the clamping ring is arranged to be provided with the two symmetric clamping ring bodies, and the opened end of the clamping ring bodies can be freely opened and closed, and therefore the drill rod can be conveniently inserted in the open end, and the problem that when the drill rod is inserted into an existing fixing device, operation is not easy is solved. The clamping blocks controlled by the reset mechanisms are arranged in the clamping ring bodies, and the clamping surfaces of the clamping blocks are arranged to the arc surfaces matched with the radian of the outer wall of the drill rod, so that the problem that when the existing fixing device clamps the drill rod, slipping easily happens is solved.

Description

technical field [0001] The invention relates to the field of fixing devices, in particular to a clamping device for fixing. Background technique [0002] In the process of oil extraction, drill pipe is an indispensable tool. Since oil wells are generally deep, the drill pipe used for oil exploitation generally uses multi-section drill pipe. When a certain section of drill pipe is damaged, replace the damaged one. One section of drill pipe is enough. When dismantling the damaged drill pipe, it is necessary to fix the two ends of the damaged drill pipe first, and then use the fixing device to disassemble the damaged drill pipe. Existing fixtures usually use a hollow cylinder to clamp the drill pipe, and the hydraulic drive device drives the fixture for fixing the drill pipe to rotate, and the fixture then drives the drill pipe to rotate in the axial direction, so that the drill pipe is disassembled. The existing fixing device is a ring structure, and the inner wall of the ri...
