Abstract

The invention discloses a fixture box on a drill pipe joint. The fixture box mainly comprises a shell, a positioning box and a locking box, wherein the positioning box is positioned at one end of the shell, and the locking box is positioned at the other end of the shell. A positioning piston is arranged in the positioning box, a locking piston is arranged in the locking box, clamps are mounted at ends of the positioning piston and the locking piston, and buffers are mounted on two sides of the shell. According to the technical scheme, the positioning piston and the locking piston are mounted in the shell of the fixture box, stable in movement trace and placed in relatively sealed clamping spaces, so that clamping torsion moment is stable, and external damage is avoided.

Description

technical field [0001] The invention relates to a fixture box used on a mud pump drill pipe joint. Background technique [0002] Before welding the drill pipe joint of the mud pump, a shackle test must be done on the joint, so that the thread and bearing surface can be loaded accordingly, so that the cooperation of the joint can be tested, thereby reducing the possibility of the thread being pierced by the mud. [0003] In the prior art, when breaking and unloading, due to the large torque inertia and the deviation of loading and unloading pressure, it is very easy to damage the joint. In addition, there are some problems that the torque requirement cannot be met, and the surface of the joint is not beautiful. , The shackle experiment takes a long time and the work efficiency is low. Contents of the invention [0004] The technical problem to be solved by the invention is that the shackle torque is unstable and the work efficiency is low. Therefore, the invention provides...
