Description
Technical field
The invention belongs to mining hydraulic field of motors, particularly relate to a kind of equal distribution angle hydraulic cylinder type motor with mining backwash filter, the power being mainly used on the coal-winning machine of colliery face, scratch board conveyor, traction locomotive and crane etc. inputs.
Background technology
Coal industry is the pillar industry of China, and the safety in coal mining is again the most important thing.Often there is gas due to underground coal mine, the main component of gas is alkane, and wherein methane accounts for the overwhelming majority; separately there is a small amount of ethane, propane and butane; in addition general possibly together with hydrogen sulfide, carbon dioxide, nitrogen and aqueous vapor, and the noble gas of trace, such as helium and argon etc..At standard conditions, methane to butane exists with gaseous state, more than pentane is liquid.Such as naked light, i.e. incendivity, there is " gas " blast, directly threaten the life security of miner.In order to reduce and prevent the generation of hair explosion accident, the requirement to underground work safety coefficient have to be high.
Along with new and high technology and the development of modern production, the yield in colliery is also in rising from year to year, coal mine equipment the most just seems even more important for the development in colliery, has become as the key factor of a restriction colliery development, and the efficiency of coal mine equipment directly affects the production efficiency of mine.Therefore the coal mine equipment of development efficient quick safety is a vital task of China's coal-mine industrial construction.
The common equipment in colliery includes coal-winning machine, scratch board conveyor, traction locomotive and overhead trolley etc..Wherein coal-winning machine is to break coal with rotary work mechanism, and it is loaded into the coal-cutting machinery of conveyer or other transporting equipments, the power source of coal-winning machine scratch board conveyor is banded cable galvanic electricity motivation and runs at work surface, and such coal-face exists unsafe factor, and danger coefficient is high.
Current mining underground scraper conveyor, its dynamical system is by driven by motor decelerator, decelerator drives the sprocket shaft group work of equipment, owing to sprocket shaft group needs frequent speed governing frequent start-stop, motor frequent start-stop is big to the impact of electrical network, and the sprocket shaft group of drag conveyor is caused the biggest impact shock by high pulling torque during start and stop, sprocket shaft group is short for service life.
And overhead trolley is not owing to being affected by base plate condition, its haulage drift arranges that convenient saving space and conevying efficiency are high.But overhead trolley technology is at home also in developmental stage, and monorail crane locomotive is walked on the track hanging on top, tunnel, by diesel engine powers, rely on running wheel to walk with interorbital frictional force drives overhead trolley.Diesel engine needs to consume substantial amounts of diesel oil in the course of the work, and it is discharged substantial amounts of high temperature hot gas and there is potential safety hazard.
Above-mentioned several coal mine machinery, traditional motor or diesel engine is used mainly due to power input, this power input mode is not suitable for coal mine machinery equipment and uses, the biggest potential safety hazard can be there is during coal mine equipment uses, cause the safety coefficient of staff under ore deposit higher, the development constraining colliery downhole equipment that the most existing power input equipment is the most serious.
Additionally, underground coal mine high-pressure emulsion need to filter Posterior circle use at present, typically use filter screen filtration, due to bad environments under ore deposit, after drainage screen uses a period of time, will pile up very many impurity on filter screen, these impurity can affect the rate of filtration and the filter efficiency of filter element, accordingly, it would be desirable in time filter element is cleared up.Need to clear up after being pulled down by filter element at present, this will shut down replacing filter screen, and impact is normal to be produced, and the most relatively costly, replacing construction is longer.
