According to which usually knew, four building elevator divides into at one, two, three, four these four floors when other floors call all sorts of situations. This has also included two simultaneous calls as well as three simultaneous calls. Another primary mission is to design the several major components’ detail drawings as well as assembly drawings on the elevator. And I mainly realized the four building elevator’s starting and stoping and those call situations through the programmable controller (PLC). But on the design of the elevator’s mechanical part, I put the emphasis on elevator’s door opener, tactor and cntrol cubicle. Of course, sdan theater box, weight these parts’ sizes also in it. I used knowledge which I have studied to complete the design on mchinery as well as electricity aspect of the four building elevator by my ownself. Keywords: elevator, programmable controller (PLC), door opener, tactor, control cubicle 一. 毕业设计课题介绍 电梯(如图1) 是随着建筑业和运输业的兴起而发展起来的一种运输工具.随着现代科学技术在电梯上的大量应用,电梯成为了一种机电一体化的大型复杂设备.电梯给人们生活,生产带来了诸多方便.但是有时候还是会出现一些小的事故,但近年来电梯已经趋于稳定. 现在的电梯已经被使用的越来越广泛了,有乘客电梯,载货电梯,客货电梯,病床电梯,住宅电梯,杂物电梯,船用电梯,观光电梯,汽车电梯,自动扶梯,自动人行道等.当然按驱动方式来说又可分为曳引式电梯,强制驱动式电梯,液压式电梯,感应式电梯.目前还有许多地
