One very huge industry.For many years, China's mining single prop has been used up emulsion as working media, live post outer surface
Using electric chromed hardened mode anti-corrosion, there is voidage due to electroplating hard chrome, thus, in underground coal mine high temperature, humidity, even
Under weak base, the adverse circumstances of weak acid, 1 year even half a year can produce corrosion phenomena.Easily sealing lip is cut on the live post surface of damage
Cut, easily extraneous dirty impurity is brought into when especially moving back and forth, so that seal failure, the damage that leaks of internal liquid is made
Fail into supporting, such as find not in time, will result in security incident.
In addition, adopting electric chromed hardened mode, electroplating effluent to there is presently no effective processing mode, dealing with improperly will
Great bodily injury is caused to local environment, is the anticorrosion process for limiting.

Handss body is connected with oil cylinder；Top cover is fixed on live post top, and closure is enclosed in inside live post；Between live post and handlebody, live post
It is provided with guide ring between oil cylinder, described handlebody, live post, closure, top cover, oil cylinder, the surface of base are equipped with
Infiltration pottery layer.
Also include O-ring one, Y shape circle, dust ring, sealed by O-ring one, Y shape circle between handlebody and live post, handlebody
The tip position being connected with live post is provided with dust ring.
O-ring two is provided between closure and live post.
Compared with prior art, the beneficial effects of the utility model are：
Overall structure is simple, it is easy to accomplish, realize sealing using various sealing rings, improve sealing effectiveness, meanwhile, metal knot
The parts surface of structure is provided with infiltration pottery layer, realizes the purpose of anti-corrosion and reinforcing, greatly improves the resistance to all kinds of corrosive powers of individual prop,
The case hardness and intensity of individual prop metal parts are improve simultaneously, improve individual prop shock resistance, anti-shell ability, while
Non-maintaining in achievable usage cycles, service life is much higher than conventional monomer pillar, and the regular service conditionss lower life-span is up to 10
Year.

Specific embodiment
This utility model is described in detail with reference to Figure of description, it should be noted that of the present utility model
Enforcement is not limited to following embodiment.
See Fig. 1, non-maintaining neutral aqueous media individual prop, including handlebody 1, live post 2, spring 3, closure 8, top cover 4,
Guide ring 7, oil cylinder 5, base 6,3 one end of spring are connected with base 6, and the other end is connected with closure 8, and live post 2 is coaxial with oil cylinder 5
It is arranged on base 6, handlebody 1 is connected with oil cylinder 5；Top cover 4 is fixed on 2 top of live post, and closure 8 is enclosed in inside live post 2；
Guide ring 7 is provided between live post 2 and handlebody 1, between live post 2 and oil cylinder 5.By O-ring between handlebody 1 and live post 2
One 9, Y shape circle 11 is sealed, and is provided with dust ring 12 at the top of the two connection；O-ring 2 10 is provided between closure 8 and live post 2,
To seal；Handlebody 1, live post 2, closure 8, top cover 4, oil cylinder 5, base 6 are processed using infiltration pottery technique.
Handlebody 1, live post 2, closure 8, top cover 4, oil cylinder 5, base 6 are workpiece, and described infiltration pottery technique processes bag
Include following steps：
1) cleaning workpiece：Workpiece is derusted with Cleaning of Parts liquid, defat, decontamination, it is and dry with the rinsing of 76～84 DEG C waters
Only (preferably 80 degrees Celsius)；
