The invention relates to a full-automatic crane rollover prevention device which comprises a frame and a shell. The shell is fixed onto the frame through an installation plate fixed to the shell; an arc-shaped bearing piece is installed on the inner side of the shell through a fixing rod; a cam is installed on the arc-shaped bearing piece in a sliding mode; the cam is connected with a counterweight assembly; a movable block is further installed on the inner side of the shell in a sliding mode through a guide assembly; a conical groove is formed in the side, facing the cam, of the movable block; the protruding part of the cam is located in the conical groove; a trigger assembly is further arranged on the guide assembly; the trigger assembly is matched with a contact piece arranged on the fixing rod; embedded grooves are formed in the frame; and supporting legs are hinged to the inner sides of the embedded grooves, and abut against torsional springs installed on the inner walls of the embedded grooves. When electromagnetic limiting assemblies work, the electromagnetic limiting assemblies are separated from the supporting legs, and the supporting legs rotate under the action of the torsional springs so as to be supported on the ground.

    本发明涉及一种全自动防吊车倾翻装置,所述全自动防吊车倾翻装置包括车架及外壳,所述外壳通过与之固定的安装板固定在所述车架上,所述外壳的内侧通过固定杆安装有弧形承接件,所述弧形承接件上滑动安装有凸轮,所述凸轮与配重组件连接,所述外壳的内侧还通过导向组件滑动安装有活动块,所述活动块朝向所述凸轮的一侧设置有锥形槽,且所述凸轮的凸起部位位于所述锥形槽内,所述导向组件上还设置有触发组件,所述触发组件与设置在所述固定杆上的接触片适配;所述车架上设置有内嵌槽,所述内嵌槽的内侧铰接有支腿,所述支腿与安装在所述内嵌槽内壁上的扭簧抵接。当电磁限位组件工作时,与支腿脱离,支腿在扭簧的作用下转动,从而支撑在地面上。
