摘   要

     帶式輸送機(jī)是現(xiàn)代物料連續(xù)運(yùn)輸?shù)闹匾�設(shè)備，是連續(xù)運(yùn)動(dòng)的無端輸送帶運(yùn)送貨物的機(jī)械，用膠帶作為輸送帶的帶式輸送機(jī)稱為膠帶輸送機(jī)，簡稱膠帶機(jī)。它是提升和運(yùn)輸機(jī)械的重要組成部分，它具有結(jié)構(gòu)簡單、成本低、運(yùn)輸距離長、效率高的優(yōu)點(diǎn)。其主要用于冶金、采礦、煤炭、電站、港口以及工業(yè)企業(yè)。它將為我國各礦業(yè)裝卸工作的機(jī)械化、現(xiàn)代化作出越來越大的貢獻(xiàn)。
現(xiàn)有技術(shù)中煤礦井下普掘矸煤運(yùn)輸設(shè)備以刮板輸送機(jī)為主，其缺陷是容易出現(xiàn)卡鏈條、斷鏈條、機(jī)頭鏈輪斷齒，卡刮板、斷刮板、底鏈易出槽等故障。另外，由于機(jī)器笨重，安裝撤除環(huán)節(jié)復(fù)雜，設(shè)備故障率高，造成工人勞動(dòng)強(qiáng)度大，工作效率低，配件投資多等問題。再者是刮板運(yùn)行過程中矸石與刮板對(duì)溜槽的擠壓或刮卡，容易產(chǎn)生火花，形成安全隱患，不利于安全生產(chǎn)。
本文針對(duì)這種情況主要介紹了一種煤礦井下掘進(jìn)矸煤運(yùn)輸簡易皮帶機(jī)。首先，介紹了帶式輸送機(jī)的工作特點(diǎn)、發(fā)展概況、工作原理及分類；其次，介紹了膠帶的摩擦傳動(dòng)原理；最后，根據(jù)帶式輸送機(jī)的工作條件對(duì)其進(jìn)行了詳細(xì)的設(shè)計(jì)計(jì)算，如驅(qū)動(dòng)裝置、機(jī)架等。此帶式輸送機(jī)結(jié)構(gòu)簡單、操作裝拆卸方便、成本低、設(shè)備安全可靠，在煤礦井下廣泛應(yīng)用。

ABSTRACT

Belt conveyer is one of most equipment used in bulk transport. Belt conveyer is continual motion machine of sideless conveying articles, using rubber belt to be conveyer belt is called rubber belt conveyer, and brief name is sealing-tape machine. Belt conveyer is an important component part of lifting and transport machinery. Its structure is very simple, and has low cost, long distance transport and very high productivity. It is mainly used in metallurgy、mining coal、power plant、port and industrial enterprises. It will make the bigger and bigger contribution for our country various mining industry loading and unloading mechanization and modernization.
In the existing technology, in coal mine common digs the gangue coal transport vehicle is mainly the scraper conveyer, its flaw is easy to appear the card chain link, to break the chain link, and the nose chain wheel breaks the tooth, the card scraper, breaks the scraper, the bottom chain is easy to overflow the breakdown and so on. Moreover, because machine is unwieldy, installment and removal link is complex, equipment failure rate is high, it creates the worker’s labor intensity in a big way, the working efficiency is low, the fitting invests is big and so on. Furthermore, in the scraper movement process the extrusion or blows the card of the gangue and the scraper to trough is easy to produce the spark, to form the hidden danger, is disadvantageous to the safety in production.
This article mainly introduced one kind of simple coal mine shaft tunneling gangue coal transportation belt conveyer in view of this kind of situation. First, it introduced the work characteristic of belt conveyer, the development survey, the principle of work and the classification; Next, it introduced the adhesive tape friction drive principle; Finally, it has carried on in detail design and calculation according to the working condition of belt conveyer, like drive, rack and so on. Its structure is simple, the installs and disassemble is convenient, the cost is low, the equipment safe is reliable, in coal mine shaft it is applied widely.
