The invention discloses a safety device for immediate reaction of a stacking machine. The safety device comprises a movable pulley block and a connecting rod mechanism, wherein the movable pulley block comprises a movable pulley, the movable pulley is installed on a pulley installation frame, the pulley installation frame is fixedly installed on a pulley fixing plate, the pulley fixing plate is installed on a bottom plate of a cargo carrying table through two lead screws, and limiting nuts are arranged at the ends, located above the pulley fixing plate, of the lead screws; and the connecting rod mechanism comprises a short rod, one end of the short rod is connected with the cargo carrying table wall through a fixing hinge pin, the short rod can rotate around the fixing hinge pin, the otherend of the short rod is installed on the lead screws below the pulley fixing plate, the middle of the short rod is hinged to an adjustable connecting rod through a hinge pin, the other end of the adjustable connecting rod is hinged to a safety tongs starting swing arm, and the safety tongs starting arm is used for starting a safety tongs. According to the safety device, the connecting rod mechanism is promoted to start the safety tongs through the self-weight sinking force of the movable pulley, the safety tongs can be started at the moment of breakage of a steel wire rope of the stacking machine to stop the cargo carrying table from falling, and potential safety hazards are reduced.
本发明公开了一种堆垛机即时反应的安全装置,包括动滑轮组和连杆机构,动滑轮组包括动滑轮,动滑轮安装在滑轮安装架上,滑轮安装架固定安装在滑轮固定板上,滑轮固定板通过两根丝杆安装在载货台底板上,丝杆位于滑轮固定板上方部分的端头处设置有限位螺母;连杆机构包括短杆,短杆的一端通过固定销轴与载货台壁连接,短杆能够绕着固定销轴转动,短杆的另一端安装在滑轮固定板下方的丝杆上,短杆的中间位置通过销轴与可调连杆铰接,可调连杆的另一端与安全钳启动摆臂铰接,安全钳启动臂用于启动安全钳。本发明利用动滑轮自重下沉的力促使连杆机构启动安全钳,可以实现堆垛机钢丝绳断裂瞬间就启动安全钳使载物台停止下坠,减少安全隐患。
