带式输送机设计及选型

摘要

带式输送机是煤矿最理想的高效连续运输设备，与其他运输设备相比，不仅具有长距离、大运量、连续输送等优点，而且运行可靠,易于实现自动化、集中化控制,特别是对高产高效矿井，带式输送机已成为煤炭高效开采机电一体化技术与装备的关键设备。皮带输送机由六个主要部件组成：传动装置，机尾和导向装置，中部机架，拉紧装置以及胶带。最后简单的说明了输送机的安装与维护。论文分析了带式输送机的选型原则及计算方法、驱动滚筒，改向滚筒的设计及减速器电机的选型。然后根据这些设计准则与计算选型方法按照给定参数要求进行选型设计；接着对所选择的输送机各主要零部件进行了校核。目前，胶带输送机正朝着长距离，高速度，低摩擦的方向发展，近年来出现的气垫式胶带输送机就是其中的一个。在胶带输送机的设计、制造以及应用方面,目前我国与国外先进水平相比仍有较大差距。本次带式输送机设计体现了设计的一般过程, 对今后的选型设计工作有一定的指导作用。

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.·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.

Next, it is the principles about choose component parts of belt conveyor., 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. 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.
