Control method of pneumatic locomotive door
The invention provides a control method for a pneumatic locomotive door. Opening and closing actions of the locomotive door are controlled by a pneumatic system. According to the control method of the locomotive door, automation of door opening, door closing and secondary pressing is achieved through control of the pneumatic system, the driving force of door opening and door closing can be adjusted by adjusting the air inflow of an air cylinder, and large driving force of secondary pressing can be achieved; in the door closing process, the door can be stopped for preventing pinching, and large door closing driving force can still be guaranteed under the condition of restarting; compared with motor control, economy and practicability are achieved, and cost is reduced; and a motor is complex in structure, and when a fault occurs, maintenance is difficult, time consumption is long, and the motor replacement cost is high. The pneumatic system is safe, reliable and low in noise, has an anti-explosion function and is suitable for actual working conditions of locomotives.
本发明提供了一种气动机车门的控制方法，所述机车门的开门、关门的动作均由气动系统控制。本发明所述的机车门的控制方法，采用气动系统控制实现开门、关门、二次压紧的自动化，可通过调节气缸的进气量调节开门关门的驱动力和实现二次压紧较大的驱动力；在关门过程中，可停顿防夹，再启动的情况下仍能保证较大的关门驱动力；相比电机控制，经济实惠，降低了成本；电机的结构复杂，当出现故障时，维修困难，耗时长，更换电机造价高。气动系统安全、可靠，噪音小，并具有防爆功能，适用于机车的实际工况。
