Description
Technical field
The invention belongs to mining hydraulic field of motors, particularly relate to a kind of with backwash single-filtering system etc. angle of distribution hydraulic cylinder type motor, be mainly used in the power input on coal-winning machine, scratch board conveyor, traction locomotive and the crane etc. of colliery face.
Background technology
Coal industry is the pillar industry of China, and the safety in coal mining is again the most important thing. Owing to often can there is gas under coal mine, the main component of gas is alkane, and wherein methane accounts for the overwhelming majority; separately there are a small amount of ethane, propane and butane; in addition generally also contain hydrogen sulfide, carbon dioxide, nitrogen and aqueous vapor, and the inert gas of trace, as helium and argon etc. Under the status of criterion, methane to butane exists with gaseous state, and pentane is liquid above. As naked light, i.e., there is " gas " blast, the life security that is directly threatening miner in incendivity. In order to reduce and prevent the generation of hair explosion accident, must be high to the requirement of underground work safety coefficient.
Along with the development of new and high technology and modern production, the output in colliery is also in rising from year to year, coal mine equipment also just seems even more important for the development in colliery, has become 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 that develops efficient quick safety is a vital task of China's coal-mine industrial construction.
The common equipment in colliery comprises coal-winning machine, scratch board conveyor, traction locomotive and overhead trolley etc. Wherein coal-winning machine is with the broken coal of rotary work mechanism, and packed into the coal-cutting machinery of conveyer or other transporting equipments, the power source of coal-winning machine scratch board conveyor is cable and drives motor to move at working face, and coal-face exists unsafe factor like this, 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, because sprocket shaft group needs frequent speed governing frequent start-stop, motor frequent start-stop is large to the impact of electrical network, and high pulling torque when start and stop causes very large impact shock to the sprocket shaft group of drag conveyor, and sprocket shaft group is short service life.
And overhead trolley is owing to not being subject to the impact of base plate condition, its haulage drift arrangement convenience save space and conevying efficiency high. But overhead trolley technology is at home also in developing stage, and monorail crane locomotive is walked hanging on the track at top, tunnel, provides power by diesel engine, rely on running wheel and the walking of interorbital frictional force drives overhead trolley. Diesel engine needs to consume a large amount of diesel oil in the course of the work, and it is discharged a large amount of high temperature hot gas and has potential safety hazard.
Above-mentioned several coal mine machinery, adopt traditional motor or diesel engine mainly due to power input, this power input mode is not suitable for coal mine machinery equipment and uses, in the process using at coal mine equipment, can there is very large potential safety hazard, cause under ore deposit staff's safety coefficient higher, therefore the serious restriction of existing power input equipment the development of colliery downhole equipment.
In addition, under coal mine, high-pressure emulsion recycles after need filtering at present, the general screen pack that adopts filters, because environment under ore deposit is severe, screen pack used after a period of time, will on filter screen, adhere to very many impurity, and these impurity can affect the rate of filtration and the filter efficiency of filter core, therefore, need in time filter core to be cleared up. Filter core need be pulled down to rear cleaning at present, this will shut down replacing filter screen, and impact is normally produced, and cost is higher simultaneously, and the replacing time is longer.
