The invention belongs to the technical field of tank car automatic control, and particularly relates to a dangerous goods gas/liquid tank car loading and unloading emergency cut-off interlocking device. A nut tee joint is fixedly installed on a gas pipe, led out of a gas storage cylinder, of a tank car, an outlet in one end of the nut tee joint is connected with a parking valve, and an outlet in the other end of the nut tee joint is connected with an electromagnetic valve; the actuator is connected with a control rod of the emergency cut-off valve, and the electromagnetic valve is electrically connected with the seven-interlocking loading and unloading vehicle system to achieve data interaction. The electromagnetic valve is electrically connected with a first electrostatic socket, a first explosion-proof connector electrically connected with the first electrostatic socket is fixedly installed on the first electrostatic socket, and the first explosion-proof connector is electrically connected with a second explosion-proof connector on a second electrostatic socket in the seven-interlocking loading and unloading vehicle system through a two-core wire. By additionally arranging the emergency cut-off valve electric control system, various safety risks occurring in the loading and unloading process of the tank car are converted into unmanned electric control automatic operation from personnel field operation, and the purpose of active safety is achieved.

    本发明属于罐车自动控制技术领域,具体涉及危险品气/液罐车装卸紧急切断联锁装置,在罐车从储气筒引出的气管上固定安装锁母三通,螺母三通一端出口连接驻车阀,螺母三通另一端出口连接电磁阀,电磁阀的控制气路与执行器连接,执行器与紧急切断阀门的控制杆连接,所述的电磁阀与七联锁装卸车系统电性连接实现数据交互。电磁阀与静电插座一电性连接,静电插座一上固定安装电性连接的防爆接头一,所述的防爆接头一通过二芯线与七联锁装卸车系统中的静电插座二上的防爆接头二电性连接。本发明通过加装紧急切断阀门电控系统,实现罐车在装卸过程中出现的各种安全风险由人员现场操作转化为无人电控自动操作,达到主动安全的目的。
