本科机械专业毕业设计——固定式带式输送机含CAD图纸.doc

本科生毕业设计 题目： 姓名： 学号： 班级： 二〇一一年六月 摘 要 本次毕业设计是关于DTⅡ型固定式带式输送机的设计。首先对胶带输送机作了简单的概述；接着分析了胶带输送机的选型原则及计算方法；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。普通型带式输送机由六个主要部件组成：传动装置、机头和机尾装置、中部机架、拉紧装置及胶带。最后简单的说明了输送机的安装与维护。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,国内在设计制造带式输送机过程中仍存在着很多不足。 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，具有输送距离长、运量大、连续运输等优点，而且运行可靠、易于实现自动化和集中化控制，尤其对高产高效矿井，带式输送已成为煤炭开采机电一体化技术与装备的关键设备，随着我国高产高效矿井的出现，原有的带式输送机无论是主参数还是运行性能都已不能满足要求，必须向长距离、高带速、大运量、大功率的大型化方向发展，并要改善和提高运行性能，确保安全可靠。 关键词：带式输送机； 选型设计； 主要部件 ABSTRACT The design is a graduation project about the belt conveyor used in coal mine. At first, it is introduction about the belt conveyor. Next, it is the principles about choose component parts of belt conveyor. 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. Take type’s transporting machine is the coal mine is the most ideal to transport an equipments efficiently and continuously,compared with other conveyance equipmentses have distance of transport long,the carrying capacity is big and continue to transport etc.advantage,and circulate credibility,be easy to the realization automation and concentrate to turn a control,particularly to high produce efficiently the m
