覆帶式擋邊帶式輸送機(jī)設(shè)計(jì)


摘要
長距離、大運(yùn)量、高速是帶式輸送機(jī)的最新發(fā)展方向。與其它輸送設(shè)備相比，帶式輸送機(jī)運(yùn)行更可靠，易于實(shí)現(xiàn)自動化和集中控制，經(jīng)濟(jì)效益十分明顯。大傾角擋邊帶式輸送機(jī)就是其中的一個。而覆帶式擋邊帶式輸送機(jī)更是彌補(bǔ)了普通擋邊機(jī)所存在的不足之處。
本文首先對普通帶式輸送機(jī)的運(yùn)用、分類、特點(diǎn)、原理作了簡單地概述，接著闡述了大傾角擋邊機(jī)的技術(shù)優(yōu)勢，引出本次設(shè)計(jì)-覆帶式擋邊帶式輸送機(jī)的設(shè)計(jì)意義；然后對整機(jī)的設(shè)計(jì)方案進(jìn)行比較選擇，在傳動方案方面，本文選取了3種傳動方式進(jìn)行比較，選出最經(jīng)濟(jì)、實(shí)用的一種方式，對驅(qū)動裝置的每個部件進(jìn)行了較為詳細(xì)的描述，然后做出選擇；接著對設(shè)計(jì)中所需要的數(shù)據(jù)進(jìn)行設(shè)計(jì)計(jì)算，再根據(jù)設(shè)計(jì)準(zhǔn)則與計(jì)算選型方法按照給定參數(shù)要求，對輸送機(jī)的傳動裝置、改向裝置、拉緊裝置、中部機(jī)架、托輥、清掃裝置等進(jìn)行選型設(shè)計(jì)；接著對輸送機(jī)的傳動滾筒軸等主要零部件進(jìn)行了強(qiáng)度校核；最后簡單地說明了輸送機(jī)的電氣及安全保護(hù)裝置。

Abstract
Long distance,large capacity,high speed is the latest development in the direction of the belt conveyor.Compared with other transportation equipments,belt conveyor is more reliable,easier to implement automation and centralized control,more obvious economic efficiency.Steep sidewall belt conveyor is one of them.Furthermore,the cover sidewall belt conveyor makes up for shortcomings that ordinary sidewall unit exists.
Firstly,the design outlines briefly the use,classification,characteristics,principles of common belt conveyor and then it describes technological advantages of the steep wall machine and it leads to this design-cover sidewall belt conveyor and what it means.Then it compares and chooses the whole machine’s design.In transmission mode,the paper compares 5 kinds of transmission mode to select the most economical and practical way,then each component is given a more detailed description and then the paper chooses the best one.After that it designs and caculates the data needed,tensioning device,the central rack,roller,cleaning devices according to the design criteria and selection method in accordance with the requirments of the given parameters.Next,it is the strength check of drive roller shaft,and other major components.At last,it is brief description of the electrical safety devices.

Key words:belt conveyor;program design;parts selection;design caculations
