A novel pneumatic winch stepless speed regulation safety operation control gas circuit comprises a gas supply gas circuit, an emergency stop module, an operation and power device, a main control box, a limiting control gas circuit, an emergency release gas circuit and an external control stop gas circuit. And main gas is taken from a gas path node with higher pressure and more stable gas pressure in a gas path, so that the third gas control valve with backpressure in a working state can be smoothly pushed to reverse during limiting triggering, and a limiting protection function is realized.

    新型气动绞车无极调速安全操作控制气路,包括供气气路、急停模块、操作及动力装置、主控箱、限位控制气路、应急释放气路和外控停车气路,本发明气控阀二的设置,在简化连接气路的同时,利用气动马达两气道的压差控制气控阀二换向,控制更加到位,动作更加灵敏,其主气取自于气路中压力较高且气压较稳定的气路节点,能够确保限位触发时顺利推动处于工作状态存在背压的气控阀三换向,实现限位保护功能。
