【摘要】：近年来,随着科学技术发展,工业生产装置规模越来越大,演变为单台设备技术集约化及体量庞大化,使得传统的吊装技术已无法满足工程建设的需求,从而衍生出多台起重机的新型、复杂、协同的吊装方法,导致大型设备吊装过程的安全风险越来越大,因此本文将以双台起重机协同吊装施工作业安全风险管理为研究对象,基于危险源辨识理论、层次分析法以及协同学模型等理论工具,对双台起重机协同吊装作业的特殊危险源进行了辨识,深入剖析人员协同、吊装起重机协同、吊装方法协同、吊装环境协同下与普通单一起重机械作业中的危险因素存在的区别,从而建立双台起重机协同吊装作业4个子系统与12个细项系统的危险源体系,通过运用层次分析法重点归纳整理出双台吊装起重机同时作业协同性方面存在的关键危险因素,主要包括:动作规划不合理、相互干涉碰撞、运行速度不均、荷载静态失衡等。同时通过建立4种关键危险源的协同核算计算公式,并基于协同理论绝热消去模型,从中挖掘关键序参量,获得对于双台起重机协同吊装关键慢驰变量。最后,基于VisualC++6.0的层次函数功能,并辅助OpenGL的仿真软件模拟仿真双台起重机吊装施工过程,模拟测试起重机各项动作执行情况,包括:双击起升、双击翻转、双击其它操作等。根据模型测试结果,深入分析关键危险源导致安全风险不可控的原因,并提出相关改进措施,并以上海化工区32万吨/年丙烯酸及酯项目为例进行实践研究,最终提出改进双台起重机吊装安全风险的建议:针对动作规划不合理、相互干涉碰撞、运行速度不均及荷载静态失衡等4个核心主要危险源基本能够实践应用,并能够实现危险源控制,因此本仿真系统在双台机协同吊装作业危险源管控及安全风险管理是有效的。
[Abstract]:In recent years, with the development of science and technology, the scale of industrial production equipment is getting larger and larger, which has evolved into a single equipment technology intensive and large volume, making the traditional hoisting technology can no longer meet the needs of engineering construction. As a result, the new, complex and cooperative hoisting methods of many cranes are derived, which leads to the increasing safety risk of the large equipment hoisting process. Therefore, this paper will take the safety risk management of double crane cooperative hoisting operation as the research object, based on the hazard source identification theory, the analytic hierarchy process and Synergetics model and other theoretical tools. In this paper, the special hazard sources of the cooperative hoisting operation of two cranes are identified, and the coordination of personnel, hoisting cranes and hoisting methods are deeply analyzed. There are differences between the dangerous factors in the hoisting environment and in the common single lifting machinery operation, thus the hazard source system of 4 subsystems and 12 fine item systems for the cooperative hoisting operation of two cranes is established. Through the use of Analytic hierarchy process to summarize the key risk factors in the coordination of two hoisting cranes at the same time, including: unreasonable action planning, interference and collision, uneven operation speed. At the same time, by establishing the calculation formula of four kinds of key risk sources, and based on the adiabatic elimination model of cooperative theory, the key order parameters are excavated. The key slow gallop variables for double crane hoisting are obtained. Finally, the hierarchical function based on VisualC 6.0 is introduced. The simulation software of OpenGL is used to simulate the construction process of double crane hoisting, and to simulate and test the execution of crane actions, including: double click hoisting, double click flip. According to the test results of the model, the causes of the uncontrollable safety risk caused by the key hazard sources are analyzed in depth, and the relevant improvement measures are put forward. Taking the 320,000 t / a acrylic acid and ester project in Shanghai Chemical Industry District as an example, the paper finally puts forward some suggestions for improving the safety risk of lifting double cranes: aiming at unreasonable operation planning, interfering with each other. The four core hazard sources, such as uneven running speed and static unbalance of load, can be applied in practice and can be controlled. Therefore, the simulation system is effective in the management of hazard source and safety risk.
