Description
Technical field
It the utility model is related to the polished rod fishing tool used in the production of oil field.
Background technology
In the production of oil field, light rod-broken occurs when running into oil well（Disconnected de- point is near wellhead flange disk）, will during failure
The measure for voluntarily dragging for bar operation is taken to be salvaged.
Concrete operations content is to be pulled out disconnected de- polished rod using oil pumper.It is urgent on disconnected de- polished rod that elevator will be salvaged
And it is sitting on packing box；By steel wire hang on polished rod eye, the lower section both ends rope sling of steel wire rope, which is hung over, salvages elevator both ends；One
People controls brake（Slowly get off the brakes）, another people station with the hands buttresses steel wire rope rope sling in well head, until rope sling is tightened, now well head
Operating personnel get out of the way；Machine is opened to pull disconnected de- polished rod out using oil pumper.
Personnel are with the purpose of hand steered firmly steel wire loop in operation：Prevent that steel wire rope is long because of elastic reaction either rope sling
And depart from elevator；Although there is anticreep tightening latch at the both ends of elevator；But the defects of rope sling disengaging factor is still present, at the same it is adjoint
Certain operational hazards.Tradition, which drags for the defects of bar operation is present and danger, to be had：
（1）Gone to help steel wire rope with hand to prevent steel wire rope from coming off, so operation is there is great danger, if steel wire
Rope, which breaks, can cause personal injury accidents or cause the damage of wellhead equipment to well head personnel；
（2）Because steel wire rope is hung directly from polished rod eye when dragging for bar, easily cause polished rod eye and drawn inclined, polished rod eye hair plait
Steel cable is damaged.
Tradition drags for the reason for bar operation is dangerous and is：
（1）, with wear pin bar limitation steel wire rope rope sling, because wearing the influence of pin and rope capacity, rope sling is easy to fall off.So
In order to prevent steel wire rope from coming off, someone is needed with hand steered positive steel wire rope；
（2）, when rope sling is longer, during rope belt load, rope sling is easily shifted over, and elevator stress can be uneven
It is even；
（3）, square clamp lower edge have corner angle, easy damaged knocks disconnected steel wire rope so that service life of steel wire rope shortens；
（4）Steel wire loop is suspended on polished rod eye, and steel wire loop can not be located at polished rod eye center during salvaging, cause center of gravity not
Surely；Steel wire loop easily causes polished rod eye hair plait flexural deformation, damages hair plait steel cable to one side swelling and hanging down of either of the testes during salvaging.
The content of the invention
In view of this, the utility model provides a kind of disconnected de- salvaging suspender of polished rod of pumping well so that employee is pumping
When motor-pumped well mouths salvage disconnected bar operation, it is not necessary to remove righting steel wire rope with hand again；Also polished rod eye hair plait will not be caused to damage.Carry
The high reliability and security of operation, protects equipment, avoids the unnecessary damage of parts, extend making for parts
Use the life-span.
For achieving the above object, the disconnected de- salvaging suspender of a kind of polished rod of pumping well provided by the utility model, including
Elevator, the elevator are made up of two square clamps, and two square clamp pairing rear bolts are connected on disconnected de- polished rod, and its feature exists
In：The lower surface of side's clamp free end is provided with groove.
Preferably, the recess edge rounding.
Preferably, square clamp groove is also equipped with curved baffle.
Preferably, horizontal retaining screw thread is machined with the contact surface of square clamp clamping polished rod.
Preferably, the salvaging suspender also includes hook mechanism.
Preferably, the hook mechanism, including roofbolt, the roofbolt top are threaded with Anti-releasing nut, roofbolt lower end
Connecting shackle.
Preferably, the suspension hook is movably connected in roofbolt lower end, and sets the anti-off-gear coordinated with suspension hook.
The beneficial effects of the utility model：
1st, the semi-circular recesses below elevator both ends, coordinate with curved baffle, there is righting steel wire rope rope sling, this
Sample with hand just without going righting, it is ensured that personal safety；Meanwhile be limited in steel wire rope in limited region, rope sling does not occur
Displacement, suspender uniform force；
2nd, the recess edge rounding below square clamp, not easy damaged knock disconnected steel wire rope；
3rd, horizontal retaining screw thread is machined with the contact surface of square clamp clamping polished rod, to clamp disconnected bar, prevents that elevator is loose
It is de-；
4th, suspension hook is suspended on the center of polished rod eye, and steel wire rope does not shift when salvaging disconnected bar, securely and reliably.
