The invention provides a pump control working platform leveling system and an aerial ladder fire truck, and the leveling system comprises a tilt angle sensor which is installed on a working platform and is used for detecting the tilt angle between the working platform and the horizontal plane and generating a tilt angle signal; the signal processing and controller module is connected with the tilt angle sensor and is used for processing the tilt angle signal and generating a control signal of the rotating speed of the servo motor; the hydraulic servo power unit is connected with the signal processing and controller module and used for outputting hydraulic power to the leveling oil cylinder according to the control signal; and the leveling oil cylinder is used for driving the working platform to rotate and level according to the hydraulic power. The hydraulic servo power unit is directly used for controlling the speed and precision of the leveling oil cylinder, a pump control system is directly adopted, and a proportional valve is not needed. The defects of an existing system are overcome, the component composition of the leveling system is simplified, and the leveling performance of the aerial ladder fire truck working platform is improved.

    本发明提供一种泵控工作平台调平系统及云梯消防车,调平系统包括:倾角传感器:安装在工作平台上,用于检测工作平台与水平面的倾角,生成倾角信号;信号处理及控制器模块:与所述倾角传感器连接,用于将倾角信号进行信号处理,生成伺服电机转速的控制信号;液压伺服动力单元:与所述信号处理及控制器模块连接,用于根据所述控制信号输出液压动力至所述调平油缸;调平油缸:用于根据所述液压动力驱动工作平台旋转调平。本发明直接通过液压伺服动力单元控制调平油缸的速度和精度本方面直接采用泵控系统,无需比例阀。解决了现有系统的缺点,简化了调平系统元件组成,提高了云梯消防车工作平台调平性能。
