Description
Technical field
The present invention relates to a kind of Nitinol peritonaeum technology, is improvements over the prior art, is specifically related to a kind of Nitinol peritonaeum technology of mine individual hydraulic prop.
Background technology
The pillar of down-hole mining work plane is one of requisite equipment on the ore deposit, the support apparatus of China's upper use in ore deposit has the various structures forms such as wooden prop, elemental metals friction prop, hydraulic prop and two telescopic suspension supporting columns, in recent years, along with the continuous developmental research of engineers and technicians and practice, support technology has a great development, and progressively be tending towards perfect, wooden prop seldom uses, the elemental metals friction prop is little and inhomogeneous because of its setting load, and perseverance increases that resistance is fallen apart from also guaranteeing and need not; Hydraulic prop is the new generation product of development after the elemental metals friction prop, applied at present more than 30 years, hydraulic prop is provided with triple-use valve, pressure liquid injection pillar oil cylinder by the triple-use valve emulsion station supply that work plane is default carries out just support, when top board is pressed and unload, by triple-use valve emulsion is gushed, pillar descends, during repeated work, the pressure liquid with the emulsion station carries out just support, successively circulation again.
Hydraulic prop is used for the place of the face roof supporting such as colliery down-hole coal excavation, constructing tunnel and heading end supporting, its main material is that the alloys such as iron, steel form by mode manufacturings such as forgings, cause 1) the colliery subsurface environment is abominable, coal-face and tunnel relative humidity are large, generally about 75%, the equipment of use is in humidity, the perishable environment for a long time; 2) because of the colliery forced ventilation, the down-hole oxygen supply is sufficient, often contains the toxic and harmfuls such as SO2, H2S, CO2, dust and gas in the air; 3) water-quality constituents is complicated, contains a large amount of K+, Na+, Fe2+, Fe3+ cation and Cl-, SO4-anion in the water quality, and its corrosivity is destroyed relevant with the water quality under the coal mine.The dissolving salt that contains higher concentration in the mine water, it is a kind of strong electrolyte, equipment is long-term to be used in the environment such as dark, moist, easily make the stanchions face produce electrochemical corrosion, cause oxidation, thereby make part-structure or overall structure corrosion, therefore need regularly pillar to be carried out preservative treatment, not only increase manpower, also wasted a large amount of time and moneys.
To sum up, existing hydraulic prop uses to the ore deposit work of adopting and brings great convenience, but still exist following problem: 1) be provided with the circular arc weld seam at the cylinder of living, caused the reduction of height of column alive, when roof weighting, the phenomenons such as brittle failure, crackle appear in weld seam easily, thereby have potential safety hazard.2) because oil cylinder inner surface is high pressure sealing face, so after the wearing and tearing, pillar is produced leak, bring hidden danger to the miner, pillar is scrapped, the learies of annual pillar reaches 300,000, causes great waste.The China's coal-mine most generally uses hydraulic prop, and according to incompletely statistics, the demand of hydraulic prop is annual to surpass 3,000,000, therefore, the further Improvement and perfection of individual prop equipment is had important practical significance.
At present, along with country constantly strengthens medium and small coal mine safety management, the coal face support overwhelming majority has been eliminated the support pattern that wooden support and traditional metal friction pillar add articulated roof beam, the long beam of metal.Therefore, since last year, the hydraulic prop market demand increases.But, because hydraulic prop market standardization is poor, drawing source channel is many, it is different that product standard is held degree, so that the individual prop product quality is uneven, individual prop vital part oil cylinder wherein only from the material to processing, plating and surfacing, very big-difference just occurred, caused very large impact for type selecting, buying, use, the maintenance in colliery, some in addition jeopardize the safety in production in colliery.In the recent period, the phenomenons such as oil cylinder bursts apart, distortion have successively appearred in ooze in Shanxi new group, large native river coking group, Handan, Hebei Mining Group, peak-to-peak group, Guizhou Pan Jiang mineral bureau.
At present, the hydraulic prop that domestic mine industry uses, it is a large amount of that all (MDT oil emulsion and water are formulated with 5:95, as transmission pillar medium with emulsion.In actual production, when moving during the circulation pillar of at every turn mining unloading, emulsion all will be discharged in a large number, can cause dying of mine down-hole working environment and mine water, has affected simultaneously the quality of mining area living water use, has caused the heavy damage of ecological environment.Along with the continuous reinforcement of Environmental Protection in China consciousness and the enforcement of the strategy of sustainable development, anticorrosion type, environment-friendly type, energy-saving hydraulic prop use popularization to become a kind of inexorable trend.
