The invention aims to provide an anti-falling safety support of a construction hoist. An inclination angle travel switch is arranged at the top end of the safety support, and by means of a method of increasing the gravity force arm of a cage and the like, a control system detects a danger signal before the running cage rises to a dangerous junction of standard joints with potential safety hazards,and a controller is triggered to act to cut off a power supply, so that the cage suddenly stops below the dangerous junction. Meanwhile, through the reverse supporting effect of the safety support, standard joints above the dangerous junction are further prevented from overturning, and the malignant safety accident that the cage and the standard joints fall off from the high altitude, and machinedamage and death happen is avoided.
本发明的目的是提供一种施工升降机防坠保险支架,在保险支架顶端装设倾角行程开关,利用增大吊笼重力力臂等方法,使得运行的吊笼在没有上升到存在安全隐患的标准节的危险接合处前,控制系统就检测到危险信号,触发控制器动作切断电源,使吊笼急停于危险接合处下方。同时,通过保险支架的反支撑作用,进一步防止危险接合处以上的标准节发生倾覆,避免吊笼和标准节从高空坠落、发生机毁人亡的恶性安全事故。
