Description
Technical field
The utility model relates to a kind of packing box for pumping well suspension arrangement, belongs to petroleum tool technical field.
Background technology
Changing pumpingh well sealed packing is that oil recovery work is to one of line service of pumpingh well.By
In on-the-spot employee, changing in sealed packing operating process, do not have special-purpose suspension arrangement to hang packing box, packing box is hung in the simple and easy hook that mostly adopts iron wire or manufacture, because the model of iron wire is different, have and slightly have carefully, also have part iron wire because service time, corrosion fracture easily occurred long afterwards, cause gland pressure cap slippage casualty accident, have more serious potential safety hazard.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of packing box for pumping well suspension arrangement.
A packing box for pumping well suspension arrangement, upper hook and fixed bar welding; Fixed bar is threaded with rotation swelling fastening devices; Rotating swelling fastening devices is connected with expansion link; Expansion link and stay fork welding.
Rotate swelling fastening devices and have tapering internal thread; Expansion link one end is connected with cross head or ring buckle; Two headbands of stay fork have 90 degree or 120 degree radians.
The utility model has the advantages that simple in structurely, make easy, easy to usely, practical, during operation, be not subject to the restriction of stop position, and can be according to the random adjustable telescopic rod length in operating space.While working during operation, rate is high, and safety is guaranteed, eliminates the potential safety hazard in operation, has good application prospect.
