The invention relates to the technical field of hoisting machinery, and particularly discloses an anti-falling limiting safety device for hoisting machinery, which comprises a mounting plate fixedly mounted on the side surface of the top end of a mechanical arm of the hoisting machinery; the two ends of the mounting shaft are fixedly mounted on the side surfaces of the mounting plates through connecting plates; the upper end of the rotating plate is rotationally connected with the mounting shaft; by arranging the first damping plate, the first damping mechanism, the second damping plate and the second damping mechanism, the purpose of prolonging the service life of a steel wire rope and a lifting hook of the hoisting machine can be achieved, and by arranging the mounting shaft, the rotating plate and the limiting damping structure, when the lifting hook moves upwards to make contact with the second damping plate, the lifting hook can continue to move upwards to make the rotating plate rotate; therefore, the whole anti-falling limiting safety device rotates to the height of the top end of a mechanical arm of the hoisting machine, and the situation that the hoisting space of a hoisted object is occupied is avoided.

    本发明涉及起重机械技术领域,具体公开了一种起重机械用防坠限位安全装置,包括:安装板,所述安装板固定安装在起重机械的机械臂顶端的侧面;安装轴,所述安装轴的两端通过连接板与安装板的侧面固定安装;旋转板,所述旋转板的上端与安装轴转动连接;本发明通过设置第一减震板、第一减震机构、第二减震板和第二减震机构,能够达到提高起重机械的钢丝绳和吊钩的使用寿命的目的,通过设置安装轴、旋转板和限位减震结构,当吊钩上移接触到第二减震板后,还能继续上移使旋转板旋转,从而使防坠限位安全装置的整体旋转到起重机械的机械臂顶端的高度,避免占用起重物品的起升空间。
