The invention provides a system for high-pressure pneumatic large-speed-ratio switching adjustment. The adjustment system comprises an air source, a manual air pressure reversing valve, an air pressure electromagnetic valve, a reversing valve, a buffer valve and a retracting and releasing actuating cylinder, wherein one path of the air source is connected to the extending port of the retracting and releasing actuating cylinder through the air pressure electromagnetic valve, the reversing valve and the buffer valve, the third connector of the reversing valve is communicated with the retractingport of the retracting and releasing actuating cylinder, and the other path of the air source is connected to the retracting and extending lock port of the retracting and releasing actuating cylinderthrough the manual air pressure reversing valve. The system for high-pressure pneumatic large-speed-ratio switching adjustment can achieve the function of switching between a high-speed speed and a low-speed speed, the high-speed/low-speed speed switching ratio reaches 5, and the adjustment system is simple in principle, low in cost, light in weight and capable of being applied to similar large-speed-conversion-ratio pneumatic systems.

    本申请提供了一种高压气动大速度比切换调节系统,所述调节系统包括气源、手动气压换向阀、气压电磁阀、换向阀、缓冲活门、收放作动筒,其中,所述气源一路通过气压电磁阀、换向阀及缓冲活门连接到收放作动筒的伸出端口,且所述换向阀的第三接口连通收放作动筒的收回端口,所述气源另一路通过手动气压换向阀连接至收放作动筒的收回和伸出锁端口。本申请提供的高压气动大速度比切换调节系统可以实现快速、慢速两种速度切换功能,快速/慢速速度切换比达到5,且本申请的调节系统原理简单,成本低,重量轻,可以应用于类似大速度变换比气动系统。
