帶式輸送機(jī)-論文

摘   要

本次是關(guān)于TD系列型皮帶輸送機(jī)的設(shè)計(jì)。首先對(duì)輸送機(jī)作了簡(jiǎn)單的概述，帶式輸送機(jī)是煤礦最理想的高效連續(xù)運(yùn)輸設(shè)備，與其他運(yùn)輸設(shè)備相比，不僅具有長(zhǎng)距離、大運(yùn)量、連續(xù)輸送等優(yōu)點(diǎn)，而且運(yùn)行可靠,易于實(shí)現(xiàn)自動(dòng)化、集中化控制,特別是對(duì)高產(chǎn)高效礦井，帶式輸送機(jī)已成為煤炭高效開(kāi)采機(jī)電一體化技術(shù)與裝備的關(guān)鍵設(shè)備。接著分析了帶式輸送機(jī)的選型原則及計(jì)算方法，例如驅(qū)動(dòng)滾筒，改向滾筒的設(shè)計(jì)及減速器電機(jī)的選型。然后根據(jù)這些設(shè)計(jì)準(zhǔn)則與計(jì)算選型方法按照給定參數(shù)要求進(jìn)行選型設(shè)計(jì)；接著對(duì)所選擇的輸送機(jī)各主要零部件進(jìn)行了校核。TD-75型皮帶輸送機(jī)由六個(gè)主要部件組成：傳動(dòng)裝置，機(jī)尾和導(dǎo)回裝置，中部機(jī)架，拉緊裝置以及膠帶。最后簡(jiǎn)單的說(shuō)明了輸送機(jī)的安裝與維護(hù)。目前，膠帶輸送機(jī)正朝著長(zhǎng)距離，高速度，低摩擦的方向發(fā)展，近年來(lái)出現(xiàn)的氣墊式膠帶輸送機(jī)就是其中的一個(gè)。在膠帶輸送機(jī)的設(shè)計(jì)、制造以及應(yīng)用方面,目前我國(guó)與國(guó)外先進(jìn)水平相比仍有較大差距。本次帶式輸送機(jī)設(shè)計(jì)代表了設(shè)計(jì)的一般過(guò)程, 對(duì)今后的選型設(shè)計(jì)工作有一定的參考價(jià)值。

Abstract
The design is a graduation project about the belt conveyor used in coal mine. At first, it is introduction about the belt conveyor. Coal belt conveyor is the ideal transport equipment in succession, as compared to other transport equipment not only has the long-distance, large volume, continuous transport, etc., but also reliable, easy to implement automated, centralized control, especially Productive and Efficient Mine, efficient coal mining belt has become mechanical and electrical integration technologies and equipment, key equipment.•
 Next, it is the principles about choose component parts of belt conveyor. For example, drive roller, bend pulley design and selection of gear motors.
After that the belt conveyor abase on the principle is designed. Then, it is checking computations about main component parts. The ordinary belt conveyor consists of six main parts: Drive Unit, Jib or Delivery End, Tail Ender Return End, Intermediate Structure, Loop Take-Up and Belt. At last, it is explanation about fix and safeguard of the belt conveyor. Today, long distance, high speed, low friction is the direction of belt conveyor’s development. Air cushion belt conveyor is one of them. At present, we still fall far short of abroad advanced technology in design, manufacture and using. There are a lot of wastes in the design of belt conveyor.
Keyword: belt conveyor; Electrotype Design; main parts
