特种设备安全课程设计自动扶梯安全评价.docVIP

　 摘 要 　　随着社会主义的日益发展，人们的生活水平逐渐提高，自动扶梯应用日益广泛，大型商场，宾馆都已离不开它，且在火车站，机场，居民楼等也愈大显身手。一个完整的扶梯系统包括梯路系统，主传动系统，梯路张紧装置，扶手系统，梳齿板，桁架，电器系统，安全保护系统。通常把电动机，主传动机构，链条机构以及制动，限速机构设计成一整体，叫做驱动机。驱动机是自动扶梯最为重要的机构，它的质量直接决定了自动扶梯的工作性能，工作状态，工作寿命等。 本设计通过对自动扶梯的基本结构的认识，考虑了各方面的因素，对自动扶梯的传动机构做了选择。辨识生产中存在的危险有害因素，查找安全隐患，运用安全系统科学的方法和安全管理的手段进行分析，评价危险有害因素的危害性或事故后果的严重性，找出事故发生的规律，提出整改方案或防范措施。 关键词：自动扶梯；电动机；驱动机装置；安全评价；分析 ABSTRACT With the development of socialism，Gradually improve the peoples standard of living，Escalator applications increasingly widespread，Shopping malls, hotels are inseparable from it，The railway station, airport, residential building,And so on.A complete escalator system including the ladder road system.A complete escalator system including the ladder road system.Main transmission system.Tensioner ladder road, rail system, comb plate, truss, electrical system, security protection system.Usually put the motor, main drive gear, chain institutions and braking, speed limit institutions design into a whole, called drive.Drive is the most important institutions of escalators, its quality directly determines the escalator work performance, work status, working life、、、、、、 This design through the understanding of the basic structure of escalator, considering various factors, driving mechanism of escalators made a choice. Identification of dangerous and harmful factors existing in production, find safe hidden trouble, using safety system science method and means of safety management were analyzed, and the evaluation of the dangers of dangerous and harmful factors or the severity of the consequences of the accident, find out the law of the accident, put forward the improvement scheme and preventive measures. Keywords:Escalator. Motor; Drive device; Safety evaluation; Analysis 目 录 1　前言 ………………………………………………………………………………1 2 衡阳市香江百货（东风店）简介及自动扶梯的类型 …………………………2 2.1 香江百货（东风店）简介 ………………………………………………2 2.2 自动扶梯的类型 …………………………………………………………2 3 自动扶梯的基本结构分析 ………………………………………………………3 3.1 驱动系统
