The invention discloses an anti-tipping device and a control method of an overhead working truck, and the anti-tipping device comprises a plurality of pressure monitoring sensors which are all arranged at the joint of a supporting leg and a supporting leg box and are used for monitoring the magnitude of vertical force borne by the supporting leg; the unloading valve is connected to a loop of the control oil way in parallel and is used for discharging hydraulic oil in the control oil way when being electrified, so that the overhead working truck stops loading action; the coding unit is mounted on the frame and is used for converting the force signal value of the pressure monitoring sensor into data information; the control unit is mounted on the frame and is used for controlling whether the unloading valve is electrified or not according to the data information transmitted by the encoding unit; the sensors are arranged at the supporting legs, the back supporting force brought by the supporting legs is monitored, whether the back supporting force exceeds the lower limit early warning value or not is judged, then the action of reducing the amplitude is correspondingly performed, and the safety control effect of the vehicle can be early warned and controlled in advance.
本发明公开了一种高空作业车的防倾翻装置及控制方法,包括:压力监测传感器,设置有多个,均设置于所述支腿和支腿箱的连接处,所述压力监测传感器用来监测所述支腿所承受竖向力的大小;卸荷阀,并联在所述控制油路的回路上,用于得电时使所述控制油路内的液压油泄出,实现所述高空作业车停止上装动作;编码单元,安装于所述车架上,其用于将所述压力监测传感器的力信号值转化为数据信息;控制单元,安装于所述车架上,其用于根据所述编码单元传递的数据信息来控制所述卸荷阀是否得电;本发明通过在支腿处设置传感器,监测支腿所带来的反支撑力,判断反支撑力是否超过下限预警值,进而对应减少幅度的动作,能提前预警控制车辆的安全控制的作用。
