Abstract:

Safety analysis of large-scale construction machine is very important to safety design and safety monitor. A three dimensional safety analysis system  was presented based on construction technology section, in which a large-scale construction machine was divided into subsystems and the construction technology into sections. Through the analyses of subsystems in each section, this system provides a systemized method for safety analysis of large-scale construction machine. Based on the presented  method, the safety analysis of 900tons bridge erector which was used in high-speed railway construction was made to instruct the safety design of this machine.

Key words: large-scale construction machine, safety analysis, safety design, three-dimensional safety analysis system

摘要：

大型施工机械的安全分析对大型施工机械的安全设计、安全监测起着非常重要的作用。提出了施工工艺驱动的大型施工机械三维安全分析体系，该三维体系将大型施工机械分为多个机械功能子系统，按施工工艺流程分为多个施工工序，通过分析机械功能子系统在各个施工工序的工作状态，对大型施工机械进行系统的安全分析。采用所提出的安全分析方法对高铁用900t架桥机进行了安全分析，给该设备的安全设计提供了有效的指导。
