摘 要
刮板輸送機是一種撓性牽引的連續(xù)輸送機械,是為采煤工作面和采區(qū)巷道運煤布置的機械。它的牽引機構(gòu)是刮板鏈,承載裝置是中部槽,刮板鏈安裝在中部槽的槽面。中部槽沿運輸路線全線鋪設(shè),刮板鏈繞經(jīng)機頭、機尾的鏈輪接成封閉形置于中部槽中,與滾筒采煤機和輸送機推移裝置配套,實現(xiàn)落煤、裝煤、運煤及推移輸送機械化。沿輸送機全長都可向溜槽中裝煤,裝入中部槽中的煤被刮板鏈拖拉,在中部槽內(nèi)滑行到卸載端卸下。
一般的刮板輸送機能在25°以下的條件使用。刮板輸送機在使用中要受拉、壓、彎曲、沖擊摩擦和腐蝕等多種作用,因此,必須有足夠的強度、剛度、耐磨和耐腐蝕性。由于它的運輸方式是物料和刮板鏈都在槽內(nèi)滑行,因此運行阻力和磨損都很大。但是,在采煤工作面運煤,目前還沒有更好的機械可代替,只能從結(jié)構(gòu)上、強度上和制造工藝上不斷研究,使它更加完善、耐用。
文中所設(shè)計的SGZ1000/2×700型輸送機傳動部主要是由電動機、減速器和彈性聯(lián)軸器組成。該輸送機橫向布置,電動機輸出的動力經(jīng)由一級錐齒輪、一級斜齒輪和一級行星輪系的傳動,最后驅(qū)動鏈輪轉(zhuǎn)動。減速器采用四行星太陽輪浮動結(jié)構(gòu),減小了結(jié)構(gòu)尺寸,同時提高整個工作面的輸送量,提高了效率。在設(shè)計過程中,對傳動部的軸、傳動齒輪、軸承和聯(lián)接用的花鍵等部件進(jìn)行了設(shè)計計算、強度校核。

Scraper conveyor
Scraper conveyor is a reprint of fully coal face ancillary equipment in the transport system an important part of the roadway in the face of the accepted face scraper conveyor unloading of coal flow, not halt the transfer to the retractable belt Conveyor boost. Bridge reversed loader with the face-scraper conveyor machine synchronous over his head, face Shearer guarantee for coal mining, and fully mechanized coal face of high yield and high efficiency operations.
Scraper conveyor is a reprint of a special structure of the scraper conveyor, powertrain and drive and scraper conveyor similar to a ramp of its fuselage and a section of the arch bridge structure and belt conveyors in the tail Paragraph above lap. In the back-alley in the coal face when the machine goes to reprint its arch bridge and all of the aircraft ended the lap belt conveyor stack of position limits, a retractable belt conveyor shortened ride Next length of the belt conveyor for the development of the shift to home-unloading nose reproduced below, can be reproduced with the face of the advance goes forward.
SGZ1000/2×700designed conveyor drive type mainly by a motor, reducer box and hydraulic coupling of the conveyor with the horizontal layout, electrical power output by the one planetary gears and a transmission gear the final drive sprocket rotation.Sun gear reducer with four planets floating structure, reducing the structure size, while improving the delivery of the entire face amount, to improve efficiency. In the design process, the Department of the drive shaft, transmission gears, bearings and spline connection with the design calculations and other components, strength analysis.
Key words:scraper conveyor;Central trough;Scraper chain。
