Technical solution of the present invention is second is that realized by following measures：A kind of well head packing using packing box sleeve
Dismantling device, including packing box sleeve, auger stem and screw thread compression bar；Auger stem includes external screw thread drillstock and augers；
Be distributed at least two internal thread holes in the sleeve body top circumference of polished rod mounting hole surrounding, screw thread compression bar and auger it is outer
Screw thread drillstock is threadably secured respectively to be mounted in internal thread hole；Augers is located in the lower part of sleeve body.
Here is the further optimization and/or improvements to invention technology described above scheme two：
The sleeve body top of above-mentioned packing box sleeve can circumference uniform distribution there are three internal thread hole, it is left to be located at polished rod mounting hole
Threaded drillpipe is fixedly installed with by screw thread respectively on the internal thread hole of right two sides；On the internal thread hole at polished rod mounting hole rear
It is threadably secured and screw thread compression bar is installed.
The cubic rotating shaft head that the top of above-mentioned screw thread compression bar and external screw thread drillstock can be fixed with convenient for spanner clamping.
Structure of the invention is reasonable and compact, easy to use；When packing is installed, packing can steadily be pressed by screw thread compression bar
Tightly between packing box and polished rod, the sealing installation of packing is realized, abrasion is small, shortens the set-up time；When packing is dismantled, spiral
Drilling rod can fix packing and sleeve body, then rotate packing by way of exiting sleeve body rotation and pull out, behaviour
Make simple and fast；Entire assembling and dissembling process does not damage polished rod, reduces labor intensity, high-efficient.
Detailed description of the invention
Attached drawing 1 is the schematic view of the front view of the embodiment of the present invention 2.
Attached drawing 2 is the A-A of attached drawing 1 to schematic cross-sectional view.
Coding in attached drawing is respectively：1 is sleeve body, and 2 be rotating handle, and 3 are open for loop bar, and 4 be external screw thread drillstock, and 5 are
Augers, 6 be screw thread compression bar, and 7 be cubic rotating shaft head, and 8 be polished rod mounting hole.
Specific embodiment
The present invention is not limited by the following examples, can determine according to the technique and scheme of the present invention with actual conditions specific
Embodiment.
In the present invention, for ease of description, the description of the relative positional relationship of each component is according to Figure of description 1
Butut mode be described, such as：The positional relationship of upper and lower, left and right etc. is the Butut direction according to Figure of description 1
Come what is determined.
Below with reference to examples and drawings, the invention will be further described：
Embodiment 1：As shown in attached drawing 1,2, which includes sleeve body 1；Sleeve body 1 is lower ending opening
Cylinder is equipped with polished rod mounting hole 8 in the top middle portion of sleeve body 1, is equipped in the middle part of the front side of sleeve body 1 and installs with polished rod
The loop bar opening 3 that hole 8 corresponds to and axially penetrates through；At least one is distributed in the 1 top circumference of sleeve body of 8 surrounding of polished rod mounting hole
A internal thread hole.
Through the invention when dismounting packing, need to be used cooperatively with conventionally known external screw rod or auger；
It when packing is installed, first has to for packing being placed in packing box, then sleeve body 1 is sleeved on by loop bar opening 3
On polished rod above packing box, sleeve body 1 is moved down to packing box along polished rod, and be fixed on outside the top of packing box；?
External screw rod is installed in internal thread hole, is steadily compressed packing by rotating external screw rod while external screw rod rotation moves down
Between packing box and polished rod, sealing is realized；Sleeve body 1 is not contacted with polished rod, does not damage polished rod；External screw rod is by packing pressure
When close envelope, since forced area is small, the abrasion to packing is reduced；Rotational resistance is small, and more convenient operation is laborsaving；
When dismantling packing, first sleeve body 1 is mounted on outside the top of packing box according to the method described above, takes auger, spiral shell
The drillstock on rotary drill top is equipped with external screw thread, and auger is by being threadably mounted in internal thread hole；Rotate auger, auger to
Lower rotation is inserted into packing, and packing and sleeve body 1 is fixed；It, can be by packing from packing while above mentioning sleeve body 1
It is extracted in box；Disassembly and assembly time is shortened, packing replacing efficiency is substantially increased.
Above-mentioned well head packing handling instrument can be made further optimization and/or improvements according to actual needs：

Screw thread, sleeve body 1 can be threadably secured outside the top for being mounted on packing box；The sleeve body 1 and packing box of threaded connection
It is convenient for disassembly and assembly；During dismantling packing, since the resistance of packing_seal is larger, by above mention sleeve body 1 by packing from
The mode extracted in packing box, more difficultly, there are some potential safety problemss；And the sleeve body 1 being connected through a screw thread is by disk
The mode that root rotation is taken out, more labor-saving, more reasonable structure；Labor intensity is reduced, safety is higher.
As shown in attached drawing 1,2, rotating handle 2 is horizontally fixed on the outer ring surface of sleeve body 1.Rotating handle 2 can be convenient for artificial hand
It is dynamic that sleeve body 1 is operated.
Embodiment 2：As shown in attached drawing 1,2, a kind of well head packing dismantling device using packing box sleeve, including packing box
Sleeve, auger stem and screw thread compression bar 6；Auger stem includes external screw thread drillstock 4 and augers 5；In 8 surrounding of polished rod mounting hole
1 top circumference of sleeve body be distributed at least two internal thread holes, the external screw thread drillstock 4 of screw thread compression bar 6 and auger is distinguished
It is threadably secured and is mounted in internal thread hole；Augers 5 is located in the lower part of sleeve body 1.Screw thread compression bar 6 can be by disk
Root is pressed between packing box and polished rod, realizes sealing；When dismantling packing, by rotating external screw thread drillstock 4,5 energy of augers
It is enough rotated down and is inserted into packing, packing and sleeve body 1 is fixed；Packing is taken out by above proposing sleeve body 1.
As shown in attached drawing 1,2, three internal thread holes are evenly distributed on 1 top of sleeve body of packing box sleeve, are located at
Threaded drillpipe is fixedly installed with by screw thread respectively on the internal thread hole of 8 left and right sides of polished rod mounting hole；After polished rod mounting hole 8
It is threadably secured on the internal thread hole of side and screw thread compression bar 6 is installed.
