摘要：【中文】本发明公开了一种实用化的道闸液压机芯。包括液压站，油路及油缸，主轴、摇杆及弹簧，角度传感器，控制系统。所述液压站通过由管接头和油管组成的油路和油缸相连，油缸推动摇杆使主轴旋转，弹簧和摇杆相连平衡道闸杆的大部分重量，角度传感器和主轴相连。本机芯结构紧凑，成本低，可靠性高，寿命长，闭环控制运行平稳。 【EN】The invention discloses a practical barrier gate hydraulic machine core. The hydraulic control system comprises a hydraulic station, an oil way, an oil cylinder, a main shaft, a rocker, a spring, an angle sensor and a control system. The hydraulic station is connected with an oil cylinder through an oil path consisting of a pipe joint and an oil pipe, the oil cylinder pushes a rocker to enable a main shaft to rotate, a spring is connected with the rocker to balance most of the weight of a barrier gate rod, and an angle sensor is connected with the main shaft. The machine core has compact structure, low cost, high reliability, long service life and stable closed-loop control operation.
