The invention relates to the technical field of construction hoists, and particularly discloses a construction hoist counterweight rope breaking anti-falling safety device which comprises a counterweight frame, a counterweight rope breaking safety device and a counterweight rope breaking safety device. Push bolt supports are symmetrically arranged on the two sides of the upper end of the counterweight frame and detachably connected with the counterweight frame, anti-falling hanging plates are rotationally arranged in the push bolt supports, U-shaped anti-falling hanging bolts are arranged at the ends of the anti-falling hanging plates, tension springs are arranged at one ends of the anti-falling hanging plates, and the lower ends of the tension springs are connected with the counterweight frame. When the steel wire rope is broken, the tension spring instantly connected with the anti-falling hanging plate shrinks and resets, then the U-shaped anti-falling hanging bolt is driven to rotate to the horizontal position from the horizontal included angle of 45 degrees to the lower plane with the rotating pin shaft as the fulcrum and then abut against the upper supporting pin shaft, the U-shaped anti-falling hanging bolt can be hung on the standard knot square frame, and the upper supporting pin shaft can limit the anti-falling hanging plate. And the U-shaped anti-falling hanging bolt is stably hung on the standard knot square frame, so that the anti-falling protection of the heavy broken rope is completed.

    本发明涉及施工升降机技术领域,具体公开了一种施工升降机对重断绳防坠落安全器装置,包括:对重架;对重架上端两侧均对称设有推栓支座,推栓支座通过可拆卸方式和对重架连接,推栓支座内转动设有防坠挂板,防坠挂板端部设有U型防坠挂栓,防坠挂板一端部设有拉簧,拉簧下端和对重架连接;当钢丝绳断绳时,瞬间连接防坠挂板的拉簧会收缩复位,进而带动U型防坠挂栓以转销轴为支点由水平夹角45°向下平面旋转到水平位置,然后抵靠在上支撑销轴上,U型防坠挂栓会挂在标准节方框上,上支撑销轴会对防坠挂板形成限位,保证U型防坠挂栓稳稳的挂在标准节方框上,这样即对重断绳防坠落保护完成。
