带式输送机系统设计北京科技本科远程与成人教育学院作业 大学论文.doc

摘 要 该课题是结合实际工程问题而制订出的一个题目，其目的是设计一套能够在给定场合下安全可靠运行的带式输送机系统。 本文是对通用设备（DTⅡ系列通用固定带式输送机）的选型计算，需要通过计算选择各组成部件。最后组合成使用于具体条件下的带式输送机。 本文设计的带式输送机为下坡运输，因此要分满载运行状态和空载运行状态两种不同工况进行分析。然后比较不同工况下所需的牵引力和电机功率，并按照最困难的工况选取出带式输送机的各部件来组成符合实际工程要求的输送机系统。 本文通过对输送机各部件的选型计算和某些重要部件的设计以使整个系统能够在给定场合下安全可靠的完成预期的任务。 关键词 带式输送机；盘式制动器；PLC Abstract This topic is a subject with practical engineering problems and work out, the purpose is to design a set of safe and reliable operation of belt conveyor system in a given situation. This paper is of universal equipment (DT series universal fixed conveyor) selection calculation, through the calculation of each component selection. Finally combined into the belt conveyor used in specific conditions. In this paper, the design of belt conveyor to transport the downhill, to full load running state and no-load running state of two different conditions were analyzed. Then compare the different conditions required tractive force and motor power, and in accordance with the most difficult conditions selected parts of belt conveyor belt conveyor system to meet the practical engineering requirements. The design of the selection calculation of conveyor components and some important parts to make the whole system can be in a given situation is safe and reliable to complete the task. 目 录 1.绪论………………………………………………………………………4 1.1 带式输送机的发展及现状………………………………………4 1.2 带式输送机的发展趋势…………………………………………6 1.3带式输送机常见问题及解决方 …………………………………7 2. 下运带式输送机的静力学设计 …………………………………8 2.1 输送带选择计算…………………………………………………8 2.2 托辊的选择计算…………………………………………………9 2.3 基本参数计算……………………………………………………11 2.4 计算牵引力及电机功率…………………………………………16 2.5 滚筒的选择………………………………………………………17 2.6 减速器的选型……………………………………………………19 2.7 制动力矩的计算及制动器的选择………………………………21 2.8 联轴器的选择……………………………………………………21 2.9 拉紧力及拉紧行程的计算及拉紧装置的选择 ………………22 2.10 软起动的选择 …………………………………………………23 3. 带式输送机的动力学特性研究 ………………………………24 3.1起动性能的分析 ……………………………………………24 4. 带式输送机电控装置 ………………………………………26 4.1电气控制操作系统开发设计技术要求 ………………………26 5. 结论 ………………………………………………………………27 参考文献………………………………………
