The invention discloses an emergency protection lifting device for a construction site. The emergency protection lifting device comprises an outer shell, a transmission cavity is formed in the outer shell, a right lead screw penetrating through the outer shell left and right is arranged below the transmission cavity, the right lead screw is arranged in the transmission cavity, and an upper end ofthe right lead screw is rotationally installed in a lower end wall of the transmission cavity through a spline sleeve, and a right support block in threaded connection with the right lead screw is arranged in the lower end wall of the transmission cavity, a left support block is arranged on a left side of the right support block, the left support block is in threaded connection with a left lead screw. When the elevator is used for loading materials to a designated height in the construction site, due to the fact that the steel cable is broken, emergency protection is carried out on the device,so that the device descends slowly, the personal safety of workers is greatly guaranteed, the accident potential of the construction site is reduced, and accidents and property loss caused by breakage of the steel rope of the elevator are effectively prevented.

    本发明公开了一种用于建筑工地的紧急保护提升装置,包括外壳体,所述外壳体内设有传动腔,所述传动腔下方设有左右贯穿外壳体内的,所述内设有右丝杠,所述右丝杠上端通过所述花键套转动安装在所述传动腔下端壁内,位于所述内设有螺纹连接在所述右丝杠上的右支撑块,所述右支撑块左侧设有左支撑块,所述左支撑块螺纹连接在左丝杠上,本发明在建筑工地使用提升机装载物料至指定高度时,因为钢索断裂对装置进行紧急保护,使其缓慢下降,从而极大的保证了工人的人生安全,并降低了工地的事故隐患,有效的防止了因提升机钢索断裂而造成的事故和财产损失。
