The invention provides an anti-shake system suitable for a folding-arm crane, which is arranged at the tail end of the folding-arm crane and comprises a static platform, dampers, a movable platform, a tail end clamp and a control unit, the static platform is connected to the tail end of a rotary joint of the folding-arm crane, and the static platform and the movable platform are connected through a plurality of dampers; the bottom end of the movable platform is connected with the tail end clamp used for clamping a workpiece, the damper and the static platform, a Hooke joint is arranged at the joint of the movable platform, a limiting rod is arranged at the center of the static platform and the center of the movable platform, a center Hooke joint is arranged at the joint of the limiting rod, the static platform and the movable platform, and the center Hooke joint is provided with an angle sensor. And the damper is used for obtaining angle information of hoisting weight swing and connected with the control unit, and the control unit adjusts the output state of each damper in real time based on the obtained angle information of hoisting weight swing so as to reduce the relative movement between the movable platform and the static platform. The swinging energy of the hoisting load is consumed through the arranged damper, and then the anti-swinging effect of the system is achieved.

    本发明提供一种适用于折臂起重机的防晃系统,设置于折臂起重机的末端,包括静平台、阻尼器、动平台、末端夹具和控制单元,静平台连接于折臂起重机的回转关节的末端,静平台和动平台之间通过若干阻尼器相连,动平台的底端连接用于夹持工件的所述末端夹具,阻尼器和静平台、动平台连接处设置有虎克铰,静平台和动平台的中心设置有限位杆,限位杆和静平台、动平台连接处设置有中心虎克铰,中心虎克铰设置有角度传感器,其用于获取吊重摆动的角度信息,其与控制单元相连,控制单元基于获取的吊重摆动的角度信息实时调整各阻尼器的输出状态,以减小动、静平台间的相对运动。本发明通过设置的阻尼器消耗吊重摆动的能量,进而实现该系统的防晃效果。
