帶式輸送機-論文

摘   要

本次是關于TD系列型皮帶輸送機的設計。首先對輸送機作了簡單的概述，帶式輸送機是煤礦最理想的高效連續(xù)運輸設備，與其他運輸設備相比，不僅具有長距離、大運量、連續(xù)輸送等優(yōu)點，而且運行可靠,易于實現(xiàn)自動化、集中化控制,特別是對高產(chǎn)高效礦井，帶式輸送機已成為煤炭高效開采機電一體化技術與裝備的關鍵設備。接著分析了帶式輸送機的選型原則及計算方法，例如驅(qū)動滾筒，改向滾筒的設計及減速器電機的選型。然后根據(jù)這些設計準則與計算選型方法按照給定參數(shù)要求進行選型設計；接著對所選擇的輸送機各主要零部件進行了校核。TD-75型皮帶輸送機由六個主要部件組成：傳動裝置，機尾和導回裝置，中部機架，拉緊裝置以及膠帶。最后簡單的說明了輸送機的安裝與維護。目前，膠帶輸送機正朝著長距離，高速度，低摩擦的方向發(fā)展，近年來出現(xiàn)的氣墊式膠帶輸送機就是其中的一個。在膠帶輸送機的設計、制造以及應用方面,目前我國與國外先進水平相比仍有較大差距。本次帶式輸送機設計代表了設計的一般過程, 對今后的選型設計工作有一定的參考價值。

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
