Abstract

The invention relates to a clamping device for fixing, which comprises a snap ring body. The snap ring body includes two symmetrically arranged snap rings. The closed ends of the two snap rings are provided with loose leaves, and the opening ends of the two snap rings are provided with screws, The fixing plate matched with the nut has multiple grooves in the clasp, and a reset mechanism is arranged in the groove, and a clamping block is arranged on the upper end of the reset mechanism. surface, the radian of the arc surface matches the drill pipe. In the present invention, the snap ring body is set as two symmetrical snap rings, so that the opening of the snap ring can be opened and closed freely, which facilitates the insertion of the drill pipe, and overcomes the problem that the existing fixing device is not easy to operate when inserting the drill pipe; through A clamping block controlled by a reset mechanism is set in the clasp, and the clamping surface of the clamping block is set to match the arc surface of the outer wall of the drill pipe, which overcomes the problem that the existing fixing device is easy to slip when clamping the drill pipe .

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...
