【摘要】：随着国民经济的快速发展,起重机械的应用越来越广泛,起重作业在现代化建设进程当中占据及其重要的地位。为准确识别和有效控制起重机械使用过程中危险因素,保障人身安全,减少事故损失,人们在不断总结事故灾难防治成功经验和失败教训的基础上,提出了安全评价的概念。安全评价既是生产经营单位实现科学化、系统化安全管理的需要,也是政府安全生产监督管理的基础。我国安全评价工作开展较晚,无论是安全评价理论和方法,还是安全评价基础数据,均与发达工业化国家存在很大差距。20世纪80年代初期,安全系统工程引入我国,受到许多大中型生产企业和行业管理部门的高度重视。本文对目前起重机监管现状进行了分析,深入研究了当前桥式起重机的各种检验规程和检验标准,提出了加强源头控制的观点,即从起重机的设计层面上进行检查,利用计算机辅助检验工作。验证与评审相结合,人与计算机结合,在最大程度上利用计算机的快速运算能力帮助检验员完成检验工作,从第三方的角度,独立地进行全方位的研究论证,对被检起重机的安全性作出合理评估。在对各种安全评价方法研究的基础上,针对桥式起重机的特点,采用了事故树分析法寻找桥式起重机的安全底事件,结合专家评议法和常规检验手段,在影响桥式起重机结构安全的诸多因素当中确定出安全评价的重点。以VC++6.0为平台开发了计算机辅助设计验证评审软件,从设计的角度出发,基于许用应力法和极限状态法对被检起重机的主要受力构件和危险截面、危险点的强度、刚度和稳定性进行验证,结合COM技术以Word输出验证评审报告。为通用桥式起重机的检验及安全评审工作提供了一个切实可行的方法。
[Abstract]:With the rapid development of the national economy, plays a more and more extensive application of heavy machinery, lifting and occupy an important position in the modern construction process. The dangerous factors in the process of heavy machinery used for accurate identification and effective control, to ensure personal safety, reduce accident loss, people in disaster prevention based continuous summary experience and lessons, put forward the concept of safety evaluation. The safety evaluation is not only the production and business units to achieve scientific, systematic safety management, is the basis of government supervision and administration of production safety.
Work safety assessment in China started late, both the theory and method of safety assessment, safety assessment and basic data, are there is a big gap between the.20 century in early 80s with industrialized countries, safety system engineering was introduced in our country, has attracted attention of many large and medium sized enterprises and industry management departments.
This paper analyzes the current regulatory status of the crane, in-depth study of the current bridge crane inspection procedures and inspection standard, put forward to strengthen the source of control points, which are examined from the crane design level, using computer aided inspection. Verification and assessment of the combination, combination of human and computer, using the fast operation ability the computer to the maximum extent to help inspectors complete inspection work, from the angle of the third party, independent research and demonstration in all aspects, to make a reasonable assessment of the safety inspection of the crane.
Based on the method of evaluation of various security, according to the characteristics of the bridge crane, the safety of bottom events of the fault tree analysis method for bridge crane, combined with expert evaluation method and conventional test methods, determine the focus of safety evaluation in many factors that affect the structure of bridge crane safety.
VC++6.0 as a platform to develop computer aided design software verification review, from the design point of view, the allowable stress method and the limit state method to be the main force component and dangerous section inspection of crane based on the dangerous points of strength, stiffness and stability are verified, combined with COM technology to verify the assessment report of the Word output. It provides a practical and feasible method for inspection and safety assessment of bridge crane.
