Moment of torsion, makes hydraulic tongs entirety not rotate with tubing string, and utilizes the internally installed coil tension spring of torsion cylinder, real
When now going up shackle, hydraulic tongs is caused down and pull on top power.Solve traditional hydraulic tongs and must rely on pincers tail rope
The problem of carrying reaction torque, the entirety simultaneously solving remotely operation hydraulic tongs is fixed and equilibrium problem.
Shackle anti-torque device on a kind of hydraulic tongs, fixed mount is to be bolted on hydraulic tongs body both sides
Two block plates, clamping hydraulic tongs be connected with inverted U torque stand bolt, play the work that can suspend hydraulic tongs in midair
With.In the middle part of inverted U torque stand crossbeam, perforate pin is connected with balancing stand crossbeam；
Two jag tops of inverted Y-shaped balancing stand are machined with pin-and-hole, with two in plane on hydraulic tongs body
Ear hole connects installs, and regulation spiral shell is installed in two jag top lateral projections of inverted Y-shaped balancing stand perforate
Nail, is used for adjusting the whole machine balancing of hydraulic tongs.The upper top of inverted Y-shaped balancing stand is machined with pin-and-hole balance
Frame crossbeam connects；Pin hole processing in the middle part of balancing stand crossbeam, connects with being connected mandrel under torsion cylinder with pin；
Flexible torsion cylinder body profile is cylinder, and endoporus is six rib holes, and cylindrical body processes outer spiral shell up and down
Stricture of vagina, is respectively mounted torsion cylinder upper press cover and torsion cylinder lower cover, opens circular hole in the middle of upper lower cover.Torsion cylinder
Under upper mandrel and torsion cylinder mandrel one end be the cylinder other end be six ribs, upper and lower mandrel six rib end is arranged on to be stretched
In contracting torsion cylinder body six rib hole, mandrel cylindrical end passes upper lower cover.Torsion cylinder spring is arranged on torsion
On cylinder under mandrel and torsion cylinder in the middle of mandrel, lower mandrel pin is connected with balancing stand crossbeam, and upper mandrel is used
Pin is connected with dovetail fixed block, dovetail fixed block and the telescoping crossbeam dovetail of the special pusher of hydraulic tongs
Slot wedge fills.
Advantages of the present invention and generation provide the benefit that: solve traditional hydraulic tongs and must rely on pincers tail rope
The problem of carrying reaction torque；Eliminate the security hidden trouble that traditional hydraulic tongs exists；Solve hydraulic tongs energy
Fixing and equilibrium problem during enough remotely operations, reduces labor intensity.Processing and fabricating is simple, maintaining
Convenient, reliable, failure rate is low.
