【正文】 ,好多廠家都是用霍爾傳感器,好一點(diǎn)的用增量編碼器,河南理工大學(xué)本科畢業(yè)設(shè)計(jì)(論文) 7 這種測(cè)速方式誤差大,受現(xiàn)場(chǎng)環(huán)境大,測(cè)速不準(zhǔn)確,因此保護(hù)就不完全,這個(gè)測(cè)速環(huán)節(jié)必須用測(cè)速發(fā)電機(jī),這樣在 PLC的程序才能更好的做到與速度有關(guān)的保護(hù)。對(duì)其在運(yùn)行過程中的加速度,減速度以及個(gè)運(yùn)行階段的行程和最后的停車位置都有精確的要求和嚴(yán)格的限制,因?yàn)樘嵘龣C(jī)始終是電力拖動(dòng)與控制的典型應(yīng)用裝置和研究對(duì)象,正確處理好礦井提升機(jī)的系統(tǒng)極其自動(dòng)化問題,對(duì)保證礦井的生產(chǎn),安全和效益具有重要意義。 經(jīng)濟(jì)性 礦井提升設(shè)備是礦山大型設(shè)備之一,功率大,耗電多,大型礦井提升機(jī)的功率超過1000KW。在我國(guó)這些規(guī)定包括在《煤礦安全規(guī)程》只中。不同類型礦井提升機(jī)的工作方式和工作環(huán)境各有所相同,但其根本的工作原理是相似的,礦井提升機(jī)提升原理示意圖如圖所示: 通過滾筒或齒輪的旋轉(zhuǎn)帶動(dòng)皮帶或鏈條升降,從而實(shí)現(xiàn)箕斗或罐籠的升降,在井下和地面之間往復(fù)運(yùn)動(dòng),進(jìn)行對(duì)煤和人員、貨物的運(yùn)輸。提升容器有罐籠和箕斗。目前在新建和改建礦井的設(shè)計(jì)中已普遍采用定量裝載設(shè)備。 (二 )箕斗裝載設(shè)備 我國(guó)過去廣泛采用鼓形箕斗裝載設(shè)備。 1.箕斗及其裝載設(shè)備 一、豎井箕斗 (一 )箕斗 我國(guó)煤礦立井廣泛采用固定斗箱底卸式箕斗,其形式有很多種,過去一些礦井普遍采用扇形閘門底卸式箕斗,現(xiàn)在新建礦井多采用平板閘門底卸式箕斗。( 5)按井筒的角度可分為;立井提升設(shè)備、斜井提升設(shè)備和露天礦斜坡提升設(shè)備。s hand in hand in frequency conversion of directly drivemore rope friction type elevator and the double rope hoist coil type, experienced more than 170 years history, At present, the mon use of the hoist a coil type inductionmotordriven hoist rope and more friction type two kinds of forms. Ascension is mainly consist of motor, gear reducer, spindle, roller ponents, between the parts by coupling could respectively. Motor is power source, reducer is transmission system, roller for implementation and control part Mine is lifting equipment along the wellbore coal gangue, ascension. Lift personnel and equipment, transfer of material mechanical equipment, It is mine production system and the ground industrial square connected hub, is the throat of the mining transport. Therefore, the mine production equipment s have an utmost important position in the ascension of the whole process. Mine is lifting equipment mine large equipment is one of the power, power consumption, large mine hoist power more than 1000 KW. Therefore mine lifting equipment cost and operation cost, also be to affect mine production technical and economic index in one of the most important factors. Reasonable option, the right to use and maintenance has important economic significance.
