The invention relates to a falling protector for lifting equipment and a control method. A building climbing frame is mounted on a connecting hole of a guide rail, one end of a lifting guide seat is fixed on a building wall, the other end of the lifting guide seat is hooped on the guide rail, the building climbing frame can move up and down along with a hook of a hoist, and the guide rail moves up and down along with the building climbing frame. The falling protector is mounted on the lifting guide seat; when the building climbing frame moves along with the guide rail at the set constant speed, a plurality of star wheel outer feet on the star wheel of the falling protector can be inserted into a plurality of rectangular holes in the guide rail in sequence, the star wheel is made to rotate, and normal lifting work of the building climbing frame can be achieved; and when the building climbing frame moves downwards at an accelerated speed along with the guide rails, the star wheels are self-locked and cannot rotate, the outer feet of the star wheels are located in the rectangular holes in the guide rails, the guide rails stop moving, the building climbing frame connected with the guide rails stops moving, and self-locking anti-falling can be completed. According to the falling protector for the lifting equipment and the control method, the anti-falling reliability of the falling protector can be enhanced, the structure is simple, pollution can be prevented, and the service life is prolonged.
本发明涉及一种用于升降设备的防坠器及控制方法，建筑爬升架安装在导轨的连接孔上，升降导座一端固定在建筑墙体上，升降导座另一端箍在导轨上，建筑爬升架能随吊葫芦的挂钩上下移动，导轨随建筑爬升架一起上下移动，防坠器安装在升降导座上；建筑爬升架随导轨按设定的速度匀速移动时，防坠器的星轮上的若干个星轮外脚能按顺序插入导轨上若干个矩形孔内，使星轮旋转，建筑爬升架能实现正常升降工作；当建筑爬升架随导轨向下加速度移动时，星轮自锁而不能旋转，星轮外脚处于导轨上矩形孔内，使导轨停止移动，与导轨连接的建筑爬升架停止移动，能完成自锁防坠。本发明能增强防坠器的防坠可靠性，且结构简单，还能防止污染，提高使用寿命。
