The invention relates to a tank-type semitrailer air brake system interlocking control tank top operation protection device and method. The tank-type semitrailer air brake system interlocking control tank top operation protection device comprises an air storage cylinder, an ABS/EBS valve, a trailer release valve, a spring energy storage double-cavity brake chamber, a brake chamber parking brake cavity connecting pipeline, a five-port two-position pneumatic control valve, a three-port two-position pneumatic control valve, a one-way valve, a three-port two-position mechanical valve, a five-port two-position hand pull valve and a double-cavity air cylinder. When a vehicle is not parked and braked, the operation guardrail cannot ascend and descend by controlling a mechanical valve and a hand-pulling valve, so that the vehicle sliding during operation is avoided, and the operation safety is ensured; in addition, when the operation guardrail does not fall down and parking braking of the vehicle is relieved, the operation guardrail can automatically fall down through interlocking control, and the automation degree is high; in addition, by means of interlocking control of a vehicle parking brake pipeline and a double-switch operation mode of an operation gas path mechanical valve and a hand-pull valve, it is guaranteed that the guardrail cannot be lifted in the vehicle running process or when the vehicle is stopped again, the mistake proofing effect is good, and the driving safety is high.
本发明涉及罐式半挂车气制动系统连锁控制罐顶作业防护装置及方法,包括储气筒、ABS/EBS阀、挂车释放阀、弹簧储能双腔制动气室、制动气室驻车制动腔连接管路、五口二位气控阀、三口二位气控阀、单向阀、三口二位机械阀、五口二位手拉阀、双腔气缸;本发明实现了车辆未驻车制动时,无法通过控制机械阀和手拉阀实现作业护栏升起、降落,避免作业溜车,确保作业安全性;且可实现在作业护栏未落下,车辆解除驻车制动行车时,通过连锁控制,作业护栏自动落下,自动化程度高;另外利用与车辆驻车制动管路连锁控制和作业气路机械阀+手拉阀的双开关操作方式,保证车辆运行过程中或再次停车时护栏不能升起,防错效果好、行车安全性高。
