The invention discloses a relieving structure for train parking braking and train parking braking equipment, and is applied to the technical field of rail transit. When the train runs normally, the parking brake isolation valve is opened, and the parking brake clamp unit is in a brake release state. And after the valve of the parking brake isolation valve is closed, gas in a brake cylinder body of the parking brake clamp unit is discharged into the atmosphere through the parking brake isolation valve, and at the moment, the parking brake clamp unit is in a brake applying state. And after the valve body of the parking brake isolation valve is closed, the power-on state of the electromagnetic valve is changed to conduct the pipeline of the electromagnetic valve, at the moment, the valve body of the electromagnetic valve is opened, the first two-way valve inflates the brake cylinder body of the parking brake clamp unit through the first air inlet, and the brake applying state of the parking brake clamp unit is relieved. By means of the relieving structure, after the parking brake clamp unit is isolated and automatically applies parking brake, a driver and passengers do not need to get off to conduct manual relieving any more, and operation convenience is improved.
本申请公开了一种列车停放制动的缓解结构、列车停放制动设备,应用于轨道交通技术领域。列车正常运行时,停放制动隔离阀的阀门打开,停放制动夹钳单元处于制动缓解状态。而停放制动隔离阀的阀门关闭后,停放制动夹钳单元的制动缸体内的气体经停放制动隔离阀排入大气,此时停放制动夹钳单元处于制动施加状态。而在停放制动隔离阀的阀门关闭后,电磁阀的通电状态变化以导通自身的管道,此时电磁阀的阀门打开,第一双向阀通过第一进气口向停放制动夹钳单元的制动缸体充气,停放制动夹钳单元的制动施加状态被缓解。通过本申请所提的缓解结构,在停放制动夹钳单元因被隔离自动施加停放制动后,不再需要司乘人员下车进行手动缓解,提高了操作的便利性。
