Electric control automatic buffering and locking escalator control method and system for ultra-large excavator
The invention discloses an electric control automatic buffering and locking escalator control method and system for an ultra-large excavator. The state of an escalator is detected through a detection switch, and when the escalator is in an unlocked state, a controller forbids the excavator to rotate. The escalator is unfolded and folded by controlling an electromagnetic directional valve to change the direction of pressure oil of an oil cylinder through an input switch. When the action is executed to a certain position, a corresponding buffer detection switch is triggered and part of pressure oil loops are cut off, so that the action speed is reduced, the impact force of a mechanical structure is buffered, the effect of protecting the mechanical structure is achieved, and the service life of the escalator is prolonged. When the escalator is completely folded, the detection switch is triggered to open a locking electromagnetic valve, so that the escalator is automatically locked. The system is further provided with an audible and visual alarm and an emergency stop switch, an audible and visual alarm is given out during action, the action of the escalator can be stopped in emergency, and accidents are avoided.
本发明公开了一种超大型挖掘机的电控自动缓冲及锁止的扶梯控制方法、系统，通过检测开关检测扶梯状态，当扶梯处在未锁止状态时控制器禁止挖机进行回转动作。扶梯的展开与收起是通过输入开关控制电磁换向阀改变油缸压力油方向实现。动作执行到一定位置时，会触发相应的缓冲检测开关并切断部分压力油回路，降低动作速度从而缓冲机械结构的冲击力，起到保护机械结构的作用延长扶梯使用寿命。扶梯完全收起时会触发检测开关打开锁止电磁阀使扶梯自动锁止。该系统还配有声光报警器与紧急停止开关，在动作时发出声光警示并且可以在紧急情况下停止扶梯的动作，避免事故发生。
