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
The present invention relates to a kind of for the fixture case in slush pump tool joint.
Background technology
Slush pump tool joint, before welding, must be done the shackle experiment on joint, and screw thread and loading end are loaded accordingly, the every cooperation of joint is checked, thereby reduced the possibility that screw thread is pierced through by mud.
In prior art, when shackle, above unload while promptly unclamping, because moment of torsion inertia is large, on unload pressure deviation, be very easy to damage joint, also having some problems is in addition not reach torque demand, joint surface is not attractive in appearance, and length consuming time, the problems such as inefficiency are tested in shackle.
Summary of the invention
Technical problem to be solved by this invention is that shackle moment of torsion is unstable, inefficiency, therefore, the invention provides a kind of quick, convenient, fixture case that moment of torsion is stable.
In order to solve the problems of the technologies described above, the invention provides the fixture case in a kind of tool joint, described fixture case is mainly to consist of housing, the locking case that is positioned at the location case of housing one end and is positioned at the housing other end, in the case of described location, there is a fixed piston, in described locking case, there is a latching ram, described fixed piston and latching ram end are all provided with pliers, in the both sides of housing, buffer are all installed.
Further, described pliers is to consist of die block, pliers die insert and pliers apron strip, described die block is fixed on described fixed piston and latching ram end, described pliers die insert is fixed on die block, described pliers apron strip is fixed on described fixed piston and latching ram end, in order to fixedly die block and pliers die insert.
Further again, described fixed piston and latching ram are by hydraulic-driven, and described buffer partial installation is in location tank shell portion, clamping housing section and locking tank shell portion.
Beneficial effect of the present invention is:
1, technical solution of the present invention adopts in fixture tank shell positioning piston and latching ram is installed, positioning piston and latching ram movement locus are stable, and in relatively airtight grasping part, therefore, the torsional moment of clamping is stable, also there will not be external injury phenomenon.
2, technical solution of the present invention adopts hydraulic power to drive clamping, and pressure stability and adjustability are strong, and a positioning piston, a latching ram coordinate, and action is simple, and operating efficiency is high, and has buffer to make buffer protection.
3, technical solution of the present invention adopts closure design, and rational in infrastructure, function admirable is practical.
