1.1帶式輸送機的的特點與應(yīng)用
帶式輸送機自1795年被發(fā)明以來，經(jīng)過兩個多世紀的發(fā)展，已被電力、冶金、煤炭、化工、礦山、港口等各行各業(yè)廣泛采用，特別是第三次工業(yè)革命帶來了新材料、新技術(shù)的采用使帶式輸送機的發(fā)展步入了一個新紀元。
當(dāng)今，無論從輸送量、運距、經(jīng)濟效益等方面來衡量，它已經(jīng)可以同火車、汽車運輸相抗衡，成為三足鼎立局面，并成為各國爭先發(fā)展的行業(yè)。
1.1.1帶式輸送機的特點
（1）結(jié)構(gòu)簡單。帶式輸送機的接由傳動滾筒、改向滾筒、托輥或無托輥部件、驅(qū)動裝置、輸送帶等幾大件組成，僅有十多種部件，能進行標準化生產(chǎn)，并可按需要進行組合裝配，結(jié)構(gòu)十分簡單；
（2）輸送物料范圍廣泛。帶式輸送機的輸送帶具有耐磨、耐酸堿、耐油、阻燃等各種性能，并耐高、低溫，可按需要進行能夠制造，因而能輸送各種散料、塊料、化學(xué)品生熟料和混凝土；
（3）輸送量大。運量可從每小時幾公斤到幾千噸，而且是連續(xù)不間距輸送，這是火車、汽車運輸望塵莫及的；
（4）運距長。單機長度可達到十幾公里一條，在國外已經(jīng)十分普及，中間無需任何轉(zhuǎn)載點。越野的帶式輸送機常使用中間摩擦驅(qū)動方式，使輸送機長度不受輸送帶強度的限制。
（5）對線路適應(yīng)性強?，F(xiàn)代的帶式輸送機在越野鋪設(shè)時，已從槽形發(fā)展到圓形，它可在水平及垂直面上轉(zhuǎn)彎，打破了槽形輸送機不能打彎的限制，因而能依山靠水，沿地形而走，可節(jié)省大量修隧道，橋梁的基建投資。
（6）裝卸十分方便。帶式輸送機可根據(jù)工藝流程需要，可在任何點上進行裝、卸料。圓管式輸送機也是如此。也可以在回程段上裝、卸料，進行反向運輸；
（7）可靠性高。由于結(jié)構(gòu)簡單，運動部件自重輕，只要輸送帶不被撕破，壽命可達十年之久，而金屬結(jié)構(gòu)部件，只要防銹好，幾十年不壞；
（8）營運費低廉。帶式輸送機的磨損件僅為托輥和滾筒，輸送帶壽命長，自動化程度高，使用人員少，平均每公里不到一人，消耗的機油和電力也很少。
（9）能耗低，效率高。由于運動部件自重輕，無效運量少，在所有連續(xù)式和非連續(xù)式運輸中，帶式輸送機耗能最低，效率最高；
（10）維修費少。帶式輸送機運動部件僅是滾筒和托輥，輸送帶又十分耐磨。相比之下，火車、汽車磨損部件要多的多，且更換磨損件也較為頻繁；
綜上所述，帶式輸送機的優(yōu)越性已十分明顯，它是國民經(jīng)濟中不可或缺的關(guān)鍵設(shè)備。加之國際互聯(lián)網(wǎng)絡(luò)化的實現(xiàn)，又大大縮短了帶式輸送機的設(shè)計、開發(fā)、制造、銷售的周期，使它更加具有競爭力。
1.2帶式輸送機的現(xiàn)狀及發(fā)展
帶式輸送機是煤礦最理想的高效連續(xù)運輸設(shè)備，與其他運輸設(shè)備相比，具有輸送距離長、運量大、連續(xù)運輸?shù)葍?yōu)點，而且運行可靠、易于實現(xiàn)自動化和集中化控制，尤其對高產(chǎn)高效礦井，帶式輸送已成為煤炭開采機電一體化技術(shù)與裝備的關(guān)鍵設(shè)備，隨著我國高產(chǎn)高效礦井的出現(xiàn)，原有的帶式輸送機無論是主參數(shù)還是運行性能都已不能滿足要求，必須向長距離、高帶速、大運量、大功率的大型化方向發(fā)展，并要改善和提高運行性能，確保安全可靠。
我國生產(chǎn)制造的帶式輸送機的品種，類型較多，在“八五”期間，通過國家一條龍“日產(chǎn)萬噸綜采設(shè)備”項目的實施，帶式輸送機的技術(shù)水平有了很大的提高，煤礦井下用大功率、長距離帶式輸送機的關(guān)鍵技術(shù)研究和新產(chǎn)品開發(fā)都取得了很大的進步。如大傾角長距離帶式輸送機成套設(shè)備，高產(chǎn)高效工作面順槽可伸縮帶式輸送機等均填補了國內(nèi)空白，并對帶式輸送機的減低關(guān)鍵技術(shù)及其主要元部件進行了理論研究和產(chǎn)品開發(fā)，研制成功了多種軟起動和制動裝置以及以PLC為核心的可編程電控裝置，驅(qū)動系統(tǒng)采用調(diào)速型液力耦合器和行星齒輪減速器。
煤礦帶式輸送機技術(shù)的發(fā)展趨勢：
設(shè)備大型化，提高運輸能力；為了適應(yīng)高產(chǎn)高效集約化生產(chǎn)的需要，帶式輸送機的輸送能力需要加大，長距離、高帶速、大運量、大功率是今后發(fā)展的必然趨勢，也是高產(chǎn)高效礦井運輸技術(shù)的發(fā)展方向，在今后的10a內(nèi)輸送量要提高到3000～4000t/h，帶速提高到4～6m/s，輸送長度對于可伸縮帶式輸送機要達到3000m。對于鋼繩芯強力帶式輸送機需加長至5000m以上，單機驅(qū)動功率要求達到1000～1500KW，輸送帶抗拉強度要達到6000N/ mm(鋼繩芯)和2500N/mm（鋼繩芯）。尤其是煤礦井下順槽可伸縮輸送技術(shù)的發(fā)展，隨著高產(chǎn)高效工作面的出現(xiàn)及煤炭科技的不斷發(fā)展，原有的可伸縮帶式輸送機，無論是主參數(shù)，還是運行性能都難以適應(yīng)高產(chǎn)高效工作面的要求，煤礦現(xiàn)場急需主參數(shù)更大，技術(shù)更先進，性能更可靠的長距離、大運量、大功率順槽可伸縮帶式輸送機，以提高我國帶式輸送機技術(shù)的設(shè)計水平，填補國內(nèi)空白，接近并趕上國際先進工業(yè)國的技術(shù)水平。其包含7個方面的關(guān)鍵技術(shù)： （1）帶式輸送機動態(tài)分析與監(jiān)控技術(shù)；（2）軟起動與功率平衡技術(shù)；（3）中間驅(qū)動技術(shù)；（4）自動張緊技術(shù)；（5）新型高壽命高速托輥技術(shù)；（6）快速自移機尾技術(shù)；（7）高速儲帶技術(shù)。
提高元部件性能和可靠性：設(shè)備開機率的高與低主要取決于元部件的性能和可靠性。除了進一步完善和提高現(xiàn)有元部件的性能和可靠性，還要不斷地開發(fā)研究新的技術(shù)和元部件，如高性能可控軟起動技術(shù)，動態(tài)分析與監(jiān)控技術(shù)，高效貯帶裝置、快速自移機尾、高速托輥等，使帶式輸送機的性能得到進一步提高。
擴大功能，一機多用化：拓展運人、運料或雙向運輸?shù)裙δ?，做到一機多用，使其發(fā)揮最大的經(jīng)濟效益。開發(fā)特殊型帶式輸送機，如彎曲帶式輸送機、大傾角或垂直提升輸送機等。
大傾角帶式輸送機突破了丄運25°的極限，為煤礦開拓，開采及在斜井輸送設(shè)備的選型開辟了一條新途徑，也為當(dāng)前斜井輸送系統(tǒng)改擴建提供了經(jīng)濟高效的設(shè)備，對提高產(chǎn)量，降低成本具有重要意義。
水平帶式輸送機在我國礦山生產(chǎn)中有著廣闊的前景。我國傾斜煤層較多，16～25°傾斜煤層大量存在。帶式輸送機能成功地用于井下，既能減少巷道開拓量和設(shè)備投資又可加快工程進度具有較大的經(jīng)濟效益。
