本文介绍了应用电气闭锁实现平车场阻车器的相互连锁及阻车器与操车设备的闭锁;采用液压常闭式挡车器,控制装置串入绞车深度指示器与绞车连锁,实现自动化控制;操车设备、阻车器、信号由一人操作,实现集中控制,避免人员配合失误造成的事故。系统先进灵敏可靠,保障提升安全。 In this paper, the application of electrical interlocking to realize the interlocking of the car stop and the blockage of the car stop and the car operation equipment by the electric lock is adopted. The control device is connected to the winch depth indicator and the winch by means of the hydraulic normally closed stop device to realize automatic control. Car equipment, car stop, the signal operated by one person, to achieve centralized control, to avoid accidents caused by staff with mistakes. The system is sensitive and reliable, guaranteeing safety.
