摘要
高铁1000 t/40 m梁“昆仑号”架桥机集简支箱梁的运输和架设于一体,可直接提吊运输箱梁到达架梁工位架梁。架桥机的前车行走机构和后车行走机构由主梁连接成一体,后车行走机构与主梁通过球铰连接;为了实现架桥机前后车同步驱动控制,研究建立了横行、直行驱动控制模型,开发了针对运架一体机的同步驱动控制系统;采用了横行、直行分类建模、定性分析、公式推导等研究方法,确定了两种行走模式采用的同步算法,完成了同步驱动控制系统硬件及软件设计;系统可适应主梁长度大、前后车行走驱动系统独立、驱动数量多且分散等因素对通驱动行走造成的影响;软硬件系统经过现场调试和试用,以及运行参数测试记录验证比较,证明驱动控制系统满足横行、直行同步指标需求,有效保证了设备行走运行的同步性,减小了行走系统不同步传递给主梁的作用力,提高了架桥机的行车运行效率并保障设备的安全稳定工作。
The high-speed rail 1000 t/40 m beam“Kunlun”bridge erection machine integrates the transportation and erection of simply supported box girder,and can directly lift and transport the box girder to the girder erection station.The traveling mechanism of the front vehicle and the traveling mechanism of the rear vehicle of the bridge erecting machine are connected into one by the main beam,and the traveling mechanism of the rear vehicle and the main beam are connected by a ball joint.In order to realize the synchronous driving control of the front and rear vehicles of the bridge erecting machine,the horizontal and straight driving control models are established,and the synchronous driving control system for the integrated machine is developed.The horizontal and straight classification modeling,qualitative analysis,formula derivation and other research methods are used to determine the synchronization algorithm in the two walking modes,and the hardware and software design of the synchronous drive control system is completed.The system can adapt to the influences of the large length of the main beam,the independent driving system of the front and rear vehicles,the large number of drives and the dispersion on the traveling of the drive.After on-site debugging and trial of the software and hardware system,as well as the verification and comparison of operating parameter test records,it is proved that the drive control system meets the requirements of horizontal and straight synchronization indicators,which effectively ensures the synchronization of the running operation of the equipment,and reduces the asynchronous transitive external force of the walking system to the main beam.The acting force improves the running efficiency of the bridge erecting machine and ensures the safe and stable operation of the equipment.
