Description
Technical field
A kind of special shaped surface coal leveling device of the present invention and using method thereof, belong to mechanical design field, be specifically related to a kind ofly can push the coal that is contained on the train to compartment medial surface space glibly, thereby make the technical scheme of smooth and uniform device of coal end face and using method thereof.
Background technology
Railway is the main channel of Coal Transport, along with the raising of train running speed and to the improving constantly of energy-conservation and environmental demands, the loading quality of coal transporting train is had very high requirement.When coal transporting train is coaling, reason owing to the mode of coalingging, cause coal in the middle of the compartment, to pile up and the few coal of rim space, so must carry out smooth and substantial, the coal that is about to pile up in the middle of the compartment is discharged to rim space and makes the coal end face smooth, to avoid transportation coal face to fly upward and to guarantee train delivery efficient.Because existing breaking down shovel effect is undesirable, artificial auxiliary flat coal is still adopted at most collieries and coal fortune station, not only speed is slow, expense is high, labour intensity is big, and human element causes the conformability of flat ature of coal amount poor, the still out of reach requirement of flat ature of coal amount in part compartment.So actv. machinery coal leveling device becomes the necessaries that coal transporting train is coaling.
The principle of work of mechanical type coal leveling device is simple, and when a joint after the compartment fills coal, along with the reach in compartment, the operating electrical machines actuating unit makes the breaking down shovel scraper plate fall the top of compartment front end, and controls the degree of depth that scraper plate falls well and begin flat coal; When scraper plate and rear end, compartment near the time, operate electrically-powered actuator again the breaking down shovel scraper plate lifted, and so forth, recycle.The effect of the flat coal of scraper plate depends on the shape of scraper plate fully, and the breaking down shovel scraper plate that uses in the production practice at present generally is the oblong scraper plate, and the scraper plate face is a simple plane, and this scraper plate can only carry out simple flat coal, and work efficiency is very low and flat coal is of poor quality.The most tangible problem of this class breaking down shovel is, when scraper plate carries out flat coal, because row's coal is not smooth, can't in time coal be pushed to the both sides in compartment, causes in the middle of the compartment coal still to pile up very high and is extended to the rear end, compartment, the last both sides that still need manually to go to fill and lead up the compartment; The breaking down shovel that also has is improving in shape a little, promptly in the middle of rectangular, weld pointed outstanding position, the row's of being beneficial to coal, though divide the coal effect that raising has been arranged, but the not smooth problem of the row's of solution coal fundamentally still, hence one can see that, if seek out desirable flat coal effect, the necessary shape to the breaking down shovel scraper plate is improved.
Summary of the invention
The purpose of a kind of special shaped surface coal leveling device of the present invention and using method thereof is, overcome the weak point in the above-mentioned existing structure, provide a kind of can arrange coal smoothly, the high efficiency special quality carries out flat coal, reduces artificial auxiliary flat coal link, saves manpower, raises the efficiency and reduce the special shaped surface coal leveling screeding device and the using method thereof of the cost of coalingging the compartment.
A kind of special shaped surface coal leveling device of the present invention, it is characterized in that it being a kind of based on fluid mechanics and principle of dynamics design-calculated special shaped surface coal leveling screeding device, by crossbeam weldment 1, special shaped surface coal leveling scraper plate 11, U type crossbeam 9, top spillplate 10, first floor 12, second floor 13, trislab 14, the 4th floor 15, left side top sheave group 2, left side downslide wheels 3, right side downslide wheels 4 and right side top sheave group 5 are formed, its special shaped surface coal leveling scraper plate 11 is for having the parabolic type Special-Shaped Surface scraper plate of the continuous mathematical feature of special-shaped curved second derivative, its special shaped surface coal leveling scraper plate 11 is welded on the left and right sides left side top sheave group 2 is housed respectively, left side downslide wheels 3, on the U type crossbeam 9 of right side downslide wheels 4 and 5 four groups of assembly pulleys of right side top sheave group, four groups of pulley mechanisms are by cylindrical pin 6, spring washer 7 and hexagonal socket nut 8 are fixed on the U type crossbeam 9, its top spillplate 10 is fixed by welding in the positive front end of U type crossbeam 9, its first floor 12, second floor 13, trislab 14 and the 4th floor 15 left and right symmetricallies are welded on special shaped surface coal leveling scraper plate 11 and the U type crossbeam 9.
