The anti-falling speed reduction device for the building construction elevator comprises a guide rail, a guide groove is formed in one side of the guide rail, a guide block is slidably connected into the guide groove, a plurality of mounting grooves are formed in the side wall of the guide groove, a first sliding groove is formed in the side wall of each mounting groove, and two first sliding blocks are slidably connected into each first sliding groove; first springs are fixed between the two first sliding blocks, connecting rods are rotatably connected to the inner sides of the first sliding blocks, a speed reduction block is rotatably connected between the two connecting rods, limiting grooves are formed in the inner walls of the two ends of the mounting groove, limiting blocks are slidably connected in the limiting grooves, permanent magnets are fixed in the speed reduction block, and electromagnets are fixed to the bottoms of the guide blocks; an energy storage mechanism is arranged in the guide block; when an elevator falls, generated airflow drives the first fan blades to rotate, then induction current is generated through the coil sleeve and the annular magnet to supply power to the electromagnet, then the speed reduction block is gradually pulled out, speed reduction is formed on the guide block till the guide block is stopped, and therefore the anti-falling speed reduction effect is achieved.

    本发明涉及一种建筑施工电梯用防坠减速装置,包括导轨,所述导轨一侧开设有导槽,导槽内滑动连接有导块,导槽侧壁开设有多个安装槽,安装槽侧壁开设有第一滑槽,第一滑槽内滑动连接有两个第一滑块,两个第一滑块之间固定有第一弹簧,第一滑块内侧转动连接有连接杆,两个连接杆之间转动连接有减速块,安装槽两端内壁均开设有限位槽,限位槽内滑动连接有限位块,减速块内部固定有永磁铁,导块底部固定有电磁铁,导块内设置有蓄能机构;本发明利用电梯坠落时,产生的气流带动第一扇叶发生转动,继而通过线圈套筒和环形磁铁产生感应电流,给电磁铁供电,继而将减速块逐渐拉出,对导块形成减速直至卡停,从而达到防坠减速效果。
