1、曳引式电梯的结构设计摘要随着建筑业发展,电梯工业也飞速发展起来,电梯是机与电紧密结合的复杂产品,为高层建筑物提供上下交通运输。本文设计的电梯为曳引式电梯,主要从机械装置部分和控制装置部分进行分析、设计及选型。机械装置部分可分为曳引系统部分和导向系统部分,提出了曳引传动机构的优越性,采用蜗轮蜗杆曳引机,曳引结构简单,降低噪声。主要任务是对主要设备选型,部分零件设计。导向系统的主要功能是限制轿厢的活动自由度,使轿厢只能沿着导轨作升降运动。在电梯系统中,终端保护装置非常重要, 是不可或缺的,它的作用在于为了防止电梯的电气系统失灵,轿厢越过上下端站后仍继续运行,继而发生冲顶或撞底事故。在电梯的电气系统
2、中,逻辑判断起着主要的作用,其控制系统必须起动各种控制信号和执行元件达到目的。目前电梯控制普遍采用 PLC 进行控制,其优点是可靠性高,程序设计方便灵活,抗干扰能力强。变频器不但可以提供良好的调速性能和准确平层性能,还可节约大量能量。关键词:电梯,曳引电梯,电梯结构,PLCIIAbstractWith the development of the construction industry, the elevator industry has developed rapidly, the elevator is the machine and electronic products in cl
