摘  要
 
 改革開放以來，社會(huì)主義市場經(jīng)濟(jì)體制初步建立，開放型經(jīng)濟(jì)已經(jīng)形成，社會(huì)生產(chǎn)力和綜合國力不斷增強(qiáng)，各項(xiàng)社會(huì)事業(yè)全面發(fā)展，人民生活總體上實(shí)現(xiàn)了由溫飽到小康的歷史性跨越。建設(shè)事業(yè)更是取得了飛速發(fā)展。
 在礦產(chǎn)開采方面，礦井提升機(jī)占有極其重要的地位，它不僅承擔(dān)將礦物從幾百米的地下運(yùn)輸至地面的功能，而且還輸送人員和設(shè)備，是整個(gè)礦井中的咽喉設(shè)備，隨著科學(xué)技術(shù)的發(fā)展及生產(chǎn)的機(jī)械化和集中化，目前，世界上經(jīng)濟(jì)比較發(fā)達(dá)的一些國家，提升機(jī)的運(yùn)行速度已經(jīng)達(dá)到20-25m/s，一次提升量達(dá)到50t，電動(dòng)機(jī)容量已超過一萬千瓦，其安全的可靠性尤為突出，如果設(shè)備提升出了故障，必然會(huì)造成停產(chǎn)。輕者影響煤炭質(zhì)量，重者則會(huì)危及人身安全。因此，我們對提升機(jī)的機(jī)械設(shè)計(jì)提出了更高的要求。提高大型卷揚(yáng)機(jī)的生產(chǎn)效率改進(jìn)其計(jì)算指標(biāo)，增加其強(qiáng)度、可靠性和使用壽命，這些都是與采用新的設(shè)計(jì)計(jì)算方法分不開的。在本次設(shè)計(jì)過程中，各部分的選型主要從礦井安全的角度來考慮，同時(shí)也保證了生產(chǎn)產(chǎn)量和效率。
 本設(shè)計(jì)主要是側(cè)重于豎井單繩纏繞式箕斗提升系統(tǒng)，主要包括如下內(nèi)容：
 （1）提升容器選擇設(shè)計(jì)；
 （2）提升鋼絲繩選擇設(shè)計(jì)；
 （3）提升機(jī)選擇設(shè)計(jì)；
 （4）提升機(jī)相對位置計(jì)算；
 （5）提升機(jī)運(yùn)動(dòng)學(xué)及動(dòng)力學(xué)計(jì)算；
 （6）電動(dòng)機(jī)容量計(jì)算等。

 Abstract
 
 A socialist market economy has built since reform and openness, and an open economy has already taken form ,the social productive forces and the comprehensive national strength have strengthened unceasingly , various social effects are  all-round development , the people’s  life have realized a historic leap from only having adequate food and clothing to leading a well-off life as a whole. Build were developing at full speed.
 In aspect of mineral exploit , the shaft hoister occupies  important position, not only it bearing pharynx and laryns equipment in secondary several hundreds meters underground , moreover the shaft transporting the personnel and equipment . With the development of science and technology , some developed countries  in the world has developed more shaft hoister at present, The hoister operation speed already reaches 20-25 meters per second , one lifting amounts reaches 50 ton , and the electric motor capacities have already reaches 10,000 kilowatts, so the safe reliability is especially important ,It may be effects the production if the equipment has something unusual ,Therefore, we have brought forward a higher request to hoister machinery design. The efficacy raising, the large-scale hoist engine, increases its intensity , reliability and life time, These are all have contact with  new design. In the process of designing , we mainly thought from the mine safety in every part selections,and we also to ensure the output and efficiency at the same time.
The designing mainly put particular emphasis on silo hoisting system , includes:（1）to choose the lifting hold;
 （2）to choose the hoist  steel wire rope;
 （3）to choose the hoister;
 （4）to scheme the relatives of the hoister;
 （5）to scheme the dynamics of the hoister;
 （6）to scheme the electromotor.
