脱水斗式提升机设计摘要.doc
摘 要 在我国选煤行业脱水斗式提升机得到了广泛应用,由于受客观条件的限制,一度发展较慢,为了提高我国脱水斗式提升机在国内外市场上的竟争力,主要针对国内现有的脱水斗式提升机普遍存在的载荷变化大、工作环境恶劣而引起的脱水斗式提升机寿命缩短等突出问题,从提高使用寿命和减少维修次数角度出发,对脱水斗式提升机进行了重新设计。 本文在常规下脱水斗式提升机设计方法的基础上,分析了常见驱动方式和链条的应用在脱水斗式提升机上的优缺点,提出该运输机可采用的驱动方式和链条型式;分析了常见增大脱水斗式提升机运量的方法,归纳总结出脱水斗式提升机设计中的关键问题和可靠驱动方案优化组合的可行方案;通过常规设计计算,提出了合理确定张紧位置、张紧方式的方法;总结了驱动装置及各主要部件的选型依据以及安装设计应注意的问题。为脱水斗式提升机的设计及应用奠定了良好的基础。 关键词脱水斗式提升机; 设计; 斗链 ABSTRACT Obtained the widespread application in the our country coal washingprofession dehydration bucket elevator,as a result of the detachment condition limit, a development is beenslower.In order to enhance our country to dehydrate the bucket elevator indomestic and foreign markets unexpectedly struggle strength,Mainly aims at the domestic existing dehydrated bucket elevatoruniversal existence the load to change dehydrated bucket elevator lossof life which big, the working conditions bad causes and so on theprominent question,Embarks from the enhancement service life and the reduced servicenumber of times angle,Has carried on the redesign to the dehydrated bucket elevator. This article in conventional dehydration bucket elevator design foundation,Has analyzed the common drive type and the chain link application onthe dehydrated bucket elevator good and bad points,Proposed this elevator may use drive type and chain link pattern;Analyzed has common increased the dehydrated bucket elevatortransportation amount the ,The induction summary sells off in the water bucket elevator designthe key question and the reliable actuation plan optimum compositionfeasible plan;Through convention design calculation,Proposed the reasonable determination tightens the position, tightensthe way the ;Summarized the drive and each major component shaping rests on as wellas installs the question which the design should pay attention。In order to dehydrate the bucket elevator design and the applicationhas laid the good foundation。 Key wordDesign Chain of pot; Transportation ; amount 目 录 1 绪论(1) 1.1脱水斗式提升机简介 (1) 1.2选题背景 (1) 1.3本课题的指导思想及主要工作 (2) 2 脱水斗式提升机关键技术分析(2) 2.1脱水斗式提升机基本组成 (2) 2.2驱动方案的确定 (3) 2.3链条的失效分析 (4) 2.4提高脱水斗式提升机输送量的技术分析(12) 3 脱水斗式提升机设计理论基础 (20) 3.1原始数据及工作条件 (20) 3.2脱水斗式提升机设计计算 (20) 4 脱水斗式提升机设计(27) 4.1斗链的选型(27) 4.2脱水斗式提升机布置形式及基本参数的确定(31) 4.3电动机的选型(32) 4.4减速器的选型(33) 4.5传动链选择与联轴器选型(34) 4.6拉紧装置选型(36) 4.7机尾的设计(38) 4.8安全装置(38) 4.9机壳和机架的设计(39) 4.10安装调试和维护(40) 结束语(42) 参考文献(43) IV
