According to the hydraulic leveling supporting leg retracting system of the large-tonnage vehicle carrying platform, a central processing unit is connected with a hydraulic pump station and a horizontal sensor and used for collecting horizontal angle information of the horizontal sensor, generating a leveling signal according to the horizontal angle information and sending the leveling signal to an oil pump motor of the hydraulic pump station; a hydraulic valve group is used for controlling retraction of the leveling supporting legs after receiving the retraction leveling signal; a horizontalsensor is used for detecting levelness of a vehicle-mounted platform. The method of the retracting system comprises the following steps of starting the pump motor, electrifying the retracting electromagnetic valve, quickly retracting, descending the vehicle-mounted platform, retracting the supporting legs in place, powering off the pump motor and the electromagnetic valve, and ending. The hydraulic leveling supporting leg retracting system for the large-tonnage vehicle carrying platform is advantaged in that potential safety hazards caused by inconsistent leveling leg retracting speed due to uneven platform load distribution when the leveling legs of the large-tonnage vehicle carrying platform are retracted can be solved with low cost, and safety of the system is improved.

    本发明的大吨位载车平台的液压调平支撑腿撤收系统,其中央处理单元与所述液压泵站和水平传感器相连接,用于采集水平传感器的水平角度信息,并根据水平角度信息产生调平信号发给液压泵站的油泵电机;液压阀组用于在接收到撤收调平信号后控制调平支撑腿的收回;水平传感器用于检测车载平台的水平度。撤收系统的方法如下:泵电机启动→撤收电磁阀得电→快速撤收→车载平台下降→撑腿撤收到位→泵电机、电磁阀失电→结束。本发明的大吨位载车平台的液压调平支撑腿撤收系统及撤收方法,具有能够以较低的成本解决大吨位载车平台在撤收调平腿时因平台载荷分布不均匀导致的调平腿撤收速度不一致带来的安全隐患、提高了系统的安全性等优点。
