攀枝花学院本科课程设计（论文）机械动力滑台PLC控制系统设计学生姓名：王文强学生学号：201110601153院（系）：机械工程学院年级专业：2011级机械设计制造及其自动化指导教师：助理指导教师：二0一四年十二月攀枝花学院本科课程设计（论文）摘要I摘要机械动力滑台在先进制造领域中扮演着极其重要的角色。因其有着进给量稳定，慢速无爬行，高速无振动，有良好的抗冲击能力，以及没有液压驱动的管路，泄露，噪声，更便于维修的优点，而应用于我们的制造生产中，为我们生产加工零件带来了方便。本文通过对机械动力滑台的电气控制、PLC的设计，采用整体化的设计思路，充分考虑了软、硬件各自的特点并进行互补优化。对系统的输入输出信号的选择、PLC机型选择及各主要电器的选择都进行了最优化的选择。最后提出了一种简单、易于实现、理论意义明确的控制策略。关键字：机械动力滑台，可编程控制器（PLC），控制电路，I/O端口攀枝花学院本科课程设计（论文）AbstractIIAbstractAlsoknownthehoistanothernameiswinch.Verticalliftingtransportmachineryisanimportantcomponentofthetieinwiththederrick,mast,pulleyblocks,andauxiliaryequipment,usedtoenhancethematerials,installationofequipmentoperations,fromhumanormechanicalpower-drivendrum,windingtractionropetocompletetheinstallationwork.Vertical,horizontalorinclinedsimpletractorLiftingheavyobjects.Twotypesofthehoistaremanualandelectrictwokinds.andNowtothemainelectricwinch.Thedesignofthe5-tonelectrichoistmotorcontionselectromotor、coupling、arrester、retarder、drum、boomsheave、asystemofpulleysset、hook,etc..Thedesignofthedrummachinebecauseofitssimplestructure,handlingtheinstallationofaflexible,convenientoperation,simplemaintenance,andoperatingenvironmentfeaturessuchasadaptability,canbeappliedtoliftingmetallurgical,construction,operationsandotherwaterconservancy,butthedesignmainlyappliedtothedrummachinefor5-tonoverheadcranehoistingmechanism.Heavywinchupgradeisoneofthemainfunctionsofthedesignofvarioustypesofwinchesarebasedonbasedonthisrequest.KEYWORDS:hoist，drum，drum，shaft攀枝花学院本科课程设计（论文）目录目录摘要..............................................................IAbstract..........................................................................................................................................II1系统控制方案的确立.............................................................................................................11.1机械动力滑台工作方式...................................................................................................11.2采用PLC控制机械动力滑台的优点...............................................................................11.3系统设计的基本步骤.......................................................................................................22机械动力滑台的控制电路.................................................................................................33PLC的输入输出点分配表...................................................................................................54PLC控制接线图.....................................................................................................................65PLC简介..................................................................................................................................75.1PLC定义...........................................................................................................................75.2PLC的特点.......................................................................................................................75.3PLC的使用情况...............................................................................................................85.3.1基本元件...............................................................................................................85.3.2工业过程控制.......................................................................................................95.3.3运动控制...............................................................................................................95.3.4数据处理...............................................................................................................95.3.5通信及联网...........................................................................................................96PLC的选择............................................................................................................................106.1三菱PLC.........................................................................................................................106.1.1三菱PLC的特点.................................................................................................106.1.2三菱FXPLC的特点..........................................................................................106.2西门子PLC.....................................................................................................................116.3欧姆龙PLC...................................................................................................................127PLC控制梯形图及语句表.................................................................................................147.1梯形图.............................................................................................................................147.2语句表............................................................................................................................158主要电器件的选择...............................................................................................................17结论.............................................................................................................................................
