The invention relates to a crane anti-overturning system, and belongs to the technical field of anti-overturning, the crane anti-overturning system comprises a crane main body, a supporting device, a counterweight device and a reverse thrust device, the supporting device is used for supporting a crane and enabling the crane to be in a horizontal stable position; the counterweight device is used for increasing the self counterweight of the crane; the thrust reverser is arranged on the side, away from a suspension arm, of the crane and comprises an ignition part, the ignition part comprises a fuel bin and an igniter, the igniter is arranged on one side of the fuel bin and used for igniting fuel in the fuel bin, and an overturning inductive sensor is arranged at the bottom of the crane body and electrically connected with the igniter. The overturning induction sensor collects overturning signals of the crane body and transmits the signals to the igniter, and the igniter ignites after receiving the signals. The device has the effects that the reverse thrust generated by combustion is matched with the counterweight device to provide additional torque for the crane main body, so that the crane is stabilized, the overturning accident of the crane is prevented, and the hoisting safety of the crane is improved.
本申请涉及一种吊车防倾覆系统,属于防倾覆技术领域,包括包括吊车主体、支撑装置、配重装置以及反推装置,支撑装置用于支撑吊车且用于使吊车处于水平稳定的位置;配重装置用于增加吊车自身配重;反推装置设于吊车远离吊臂的一侧,反推装置包括点火部,点火部包括燃料仓和点火器,点火器设于燃料仓的一侧,点火器用于点燃燃料仓内的燃料,吊车主体底部设有倾覆感应传感器,倾覆感应传感器与点火器电性连接,倾覆感应传感器收集吊车主体的倾覆信号,并将信号传输给点火器,点火器接收信号后点火。本申请具有利用燃烧产生的反推力,与配重装置配合为吊车主体提供额外的力矩,进而用于稳定吊车,防止其发生倾覆事故,提高吊车起吊安全性的效果。
