Abstract
An extractor for rod-pumped well opening packing comprises a packing box pressing cap, a straightening cylinder, a connection screw and packing hooks. The extractor is characterized in that the straightening cylinder is of an opposite fastening type cylinder shape, the diameter of the upper portion is larger than the diameter of the lower portion, a male thread connected with the packing box pressing cap is arranged on the upper portion, the four packing hooks are vertically and symmetrically arranged at the lower end downwards, and a pressing side is arranged on the opposite fastening portion of the straightening cylinder and provided with a screw hole and the connection screw. The extractor has the advantages that by means of the gravity and the downward-smashing force, the packing hooks are inserted into the packing, then the packing can be taken out one piece by one piece, and therefore the time and the labor can be saved, and operation is fast.
Description
Technical field
The utility model relates to the oil pumping well head packing extractor of using when a kind of rod-pumped well is changed well head sealing packing.
Background technology
At present, oil recovery workman is in the time changing well head sealing packing, that a personal pipe wrench is stuck in packing box pressing cap and gland on the polished rod that does not affect the height point of changing packing, another person changes packing, because tripping out old packing, to change new building Gent not hard, especially plays last packing more difficult, and replacing packing must need more than one hour, waste time and energy, rate while affecting oil well production.
Summary of the invention
The purpose of this utility model is to provide a kind of oil pumping well head packing extractor, overcomes the defect that above-mentioned prior art exists.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises packing box pressing cap, righting cylinder, connecting screw and packing hook, it is characterized in that righting cylinder is made as button type cylindrical shape, the large lower diameter of upper diameter is little, top is provided with the male thread being connected with packing box pressing cap, lower end is provided with four symmetrical packing hooks vertically downward, righting cylinder buckle is provided with to flanging, in flanging, be provided with screw hole and connecting screw.
Righting cylinder top external diameter equates with wellhead packing box external diameter, and lower outer diameter is less than warp in wellhead packing box, is highly greater than the degree of depth of packing box.
The utility model has the advantages that: by gravity of the present utility model and under pound power, packing hook is penetrated packing, just packing can be taken out one by one, time saving and energy saving fast.
Accompanying drawing explanation
Accompanying drawing-structural representation of the present utility model;
In figure: 1-packing box pressing cap 2-righting cylinder 3-connecting screw 4-packing hook
The specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model comprises packing box pressing cap 1, righting cylinder 2, connecting screw 3 and packing hook 4, it is characterized in that righting cylinder is made as button type cylindrical shape, the large lower diameter of upper diameter is little, top is provided with the male thread being connected with packing box pressing cap, lower end is provided with four symmetrical packing hooks vertically downward, righting cylinder buckle is provided with to flanging, in flanging, be provided with screw hole and connecting screw.
In the time of application the utility model, first by the packing box pressing cap unloading and packing gland, by two lobe counterparts of righting cylinder on polished rod, withstand packing box pressing cap and packing gland, be integrally connected by connecting screw, packing box pressing cap is threaded with righting cylinder, then righting cylinder is put into packing box, on put and pound, packing hook penetrates in packing, packing can be taken out one by one.Time saving and energy saving quick.
