- 皮帶輸送機-畢業設計參考Belt conveyor is the main component which is used to carry goods continued nowadays. With the development of the industry and technology, adopting to lager-amount long-length high –speed, the design method of large belt conveyor which is used to carry goods continued has been mostly studied. According to the belt conveyor drive principle, the paper uses point by point method to have a design, and with the given facts, magnize the model chose drive installment、roller roll belt pulling hydraulic. The drive installment adopts the advanced hydraulic soft drive system and hydraulic pull automatic system.Belt conveyor is the most ideal efficient coal for transport equipment, and other transport equipment, not only has compared long-distance large-capacity, continuous conveying wait for an advantage, and reliable operation, easy to realize automation, centralized control, especially for high yield and high efficiency mine, belt conveyor has become coal high-efficient exploitation mechatronics technology and equipment the key equipment.

前言
礦井開采是整個國家乃至世界的工業基礎,而其產品運輸又是最重要的工序之一,它的成本直接關系到工業各部門。所以,世界各國都在不斷的改革礦井運輸問題。大型礦井采用的運輸方式有自卸汽車運輸、鐵路運輸和膠帶運送及運輸等。其中,膠帶運送機運輸可謂是目前最先進的礦井開采新工藝。本次設計的主要內容即膠帶輸送機。
膠帶輸送機是現代散狀物料連續運輸的主要設備。越來越多的工程技術人員對膠帶機的設計方法進行了大量的研究。我們將以經濟、可靠、維護方便為出發點,對膠帶機進行設計計算,并根據計算數據對驅動裝置、托輥、滾筒、輸送帶、拉進裝置以及其他輔助裝置進行嚴格選型。
由于帶式輸送機的結構特點決定了其具有優良性能,主要表現在:運輸能力大,且工作阻力小,耗電量低,約為刮板輸送機的1/3到1/5;由于物料同輸送機一起移動,同刮板輸送機比較,物料破碎率小;帶式輸送機的單機運距可以很長,與刮板輸送機比較,在同樣運輸能力及運距條件下,其所需設備臺數少,轉載環節少,節省設備和人員,并且維護比較簡單。由于輸送帶成本高且易損壞,故與其它設備比較,初期投資高。
輸送機年工作時間一般取4500-5500小時。當二班工作和輸送剝離物,且輸送環節較多,宜取下限;當三班工作和輸送環節少的礦石輸送,并有儲倉時,取上限為宜。
電動機通過聯軸器、減速器帶動傳動滾筒轉動或其他驅動機構,借助于滾筒或其他驅動機構與輸送帶之間的摩擦力使輸送帶運
