【正文】 I 摘 要 刮板輸送機(jī)是一種 具 有撓性牽引機(jī)構(gòu)的連續(xù)運(yùn)輸機(jī)械， 主要供采煤工作面使用。 在煤礦井下綜采工作面中主要承擔(dān)的任務(wù)是將采煤機(jī)采下的原煤連續(xù)不斷地運(yùn)往轉(zhuǎn)載機(jī)，確保綜采工作面的原煤連續(xù)運(yùn)出。 它要求機(jī)身高度小，便于裝載；運(yùn)輸能力滿足使用地點(diǎn)的生產(chǎn)需要；結(jié)構(gòu)堅(jiān)固 ， 能抵抗壓、砸和碰撞；變更運(yùn)輸距離時(shí)，加長(zhǎng)和縮短方便；能夠不拆卸用機(jī)械移置。 根據(jù)所給設(shè)計(jì)參數(shù)和工作環(huán)境的要求， 通過對(duì) 刮板輸送機(jī) 的 發(fā)展情況、發(fā)展趨勢(shì)、 結(jié)構(gòu)組成、工作原理、種類 及 作用 進(jìn)行分析 ， 對(duì) SGD730/180 型刮板輸送機(jī) 輸送能力的計(jì)算、水平彎曲段幾何 參數(shù)的計(jì)算、運(yùn)行阻力的計(jì)算、鏈條張力和牽引力的計(jì)算、電機(jī)功率的計(jì)算、溜槽推移阻力的計(jì)算、鏈條預(yù)張力和緊鏈力的計(jì)算及鏈條強(qiáng)度的計(jì)算等 ，完成刮板輸送機(jī)結(jié)構(gòu)改進(jìn) ，繪制了 SGD730/180 型刮板輸送機(jī)總圖、機(jī)頭傳動(dòng)裝置等結(jié)構(gòu)設(shè)計(jì) 。 完成 了 The use of Scraper conveyor 的 翻譯工作。 關(guān)鍵詞 刮板輸送機(jī) 結(jié)構(gòu)設(shè)計(jì) 理論計(jì)算 II Abstract Scraper conveyor is a kind of flexible traction for the transport machinery, Primarily for the use of coal face. Fully mechanized coal mine in the coal face of the main tasks is to undertake the mining of coal Shearer continuously reproduced to the machine, Ensure that the fully mechanized coal face of the coal for export. It requires a high degree of the fuselage of small, easy loading。 The use of transport capacity to meet the needs of production sites。 Solid structure, can resist pressure, smashing and collision。 Change the distance, the lengthening and shortening the convenience。 can not demolished by mechanical removal. According to the design parameters and environmental requirements, the scraper conveyor through the development of the situation, the trend of development, structure, working principle, types and roles of the SGD730/180scraper conveyor transport capability of calculation , The level of the bending of the geometric parameters, the operation of the resistance, the chain tension and the traction, electrical power, the resistance to passage of the chute, the chain of pretension and tight links of the chain of calculation and the calculation of strength, to plete scratch Board conveyor structure improvement, drawnscraper conveyor SGD730/180 the map, the nose gear, such as structural design. Completed The use of Scraper conveyor of the translation work. Key words Scraper conveyor Structural Design Theoretical calculations III 目 錄 摘 要 .......................................................................................................................
