【摘要】 熔融金属起重机是冶金行业高温熔融金属转运环节的主要设备,熔融金属起重机长期工作在高温、高粉尘、重载等特殊工作环境下,运行过程中频繁的启动,制动等生产运行过程,使得其结构和机构性能不断退化,需要及时对这些故障进行预判和发现,避免在熔融金属转运作业过程中的倾翻、脱轨等重大事故。制动系统对于高温熔融金属转运的起重机运行安全保障具有重要作用,因此对制动系统的监控尤为重要。本文开展了对熔融金属起重机制动系统监控的技术研究,通过对制动系统的故障判断分析,确定了吊运过程中保证储运容器稳定运行的制动特征参数并设计了检测技术和故障判断方法,采用柔性阵列压力检测技术监测制动器运行状态,设计了柔性阵列压力传感器,研发了制动设备的制动过程与制动性能的监测设备,制动系统监控采用MCGS组态软件的网络版,对数据信号进行实时监控和监控画面的图像显示。传感器阵列信号采集采用分布式设备,通过MODBUS现场总线与工业计算机交互信息。本文最后对监控系统进行了功能测试,检测结果符合预期,最终实现了对数据信号进行实时监控和监控画面的图像显示,实现了制动系统实时监控、实时曲线与历史曲线、报警处理、系统运行参数设置、故障判断等功能。更多还原

【Abstract】 Casting cranes are the main equipment for the transfer of high-temperature molten metals in the metallurgical industry.Casting cranes have been working in special working environments such as high temperature,high dust and heavy loads for a long time.During the operation,they frequently start and brake and other production and operation processes,which make their structure and The performance of the mechanism is constantly degrading,and it is necessary to predict and discover these failures in time to avoid major accidents such as tipping and derailment during molten metal transfer operations.The braking system plays an important role in the safety and security of the casting crane for high-temperature molten metal transfer,so the monitoring of the braking system is particularly important.This paper has carried out the technical research on the monitoring of the brake system of the molten metal crane.Through the fault judgment and analysis of the brake system,the brake characteristic parameters that ensure the stable operation of the storage and transportation container during the lifting process are determined and the detection technology and fault judgment are designed.Methods: Use flexible array pressure detection technology to monitor the operating status of brakes,design flexible array pressure sensors,develop monitoring equipment for braking process and braking performance of brake equipment,and use the network version of MCGS configuration software for brake system monitoring,Real-time monitoring of data signals and image display of monitoring screens.The sensor array signal acquisition adopts distributed equipment,and exchanges information with industrial computers through MODBUS field bus.At the end of this paper,a functional test of the monitoring system is carried out to realize real-time monitoring of data signals and image display of monitoring screens,real-time monitoring of the brake system,real-time curve and historical curve,alarm processing,system operation parameter setting,fault judgment,etc.更多还原
