The invention discloses an anti-falling speed reducer for a building construction elevator, and relates to the technical field of construction elevators. The anti-falling speed reducer comprises an elevator car body and a wall body, wherein a speed reduction mechanism is arranged at the bottom of the elevator car body, an anti-falling mechanism is arranged at the top of the elevator car body, the speed reduction mechanism comprises an acceleration sensor; the acceleration sensor is fixedly installed in an inner cavity of the elevator car body, and a wall body speed reduction mechanism is arranged on the inner side of the wall body. By adopting the combination of the acceleration sensor, a reverse magnetic block and a magnetic block, if the elevator car falls, the acceleration sensor can detect that the acceleration of the elevator car is abnormal, then a hydraulic push rod is controlled to be started, a fixing column is pushed to slide at the bottom of a sliding groove plate, and then the reverse magnetic block and the magnetic block are prompted to be stopped after being located on a same vertical line; through the principle that like poles of the magnetic block and the reverse magnetic block repel each other, the function of reducing the falling speed of the elevator car can be achieved, and the problem that a safety device is difficult to start normally when an elevator falls rapidly is solved.

    本发明公开了一种建筑施工电梯用防坠减速装置,涉及施工电梯技术领域,包括电梯箱体和墙体,所述电梯箱体的底部设置有减速机构,所述电梯箱体的顶部设置有防坠机构,所述减速机构包括加速度传感器,所述加速度传感器固定安装在电梯箱体的内腔中,所述墙体的内侧设置有墙体减速机构。本发明通过采用加速度传感器、反向磁块和磁力块的结合,若电梯箱体发生坠落,加速度传感器会检测到电梯箱体的加速度异常,随之控制液压推杆启动,推动固定柱在滑槽板的底部滑动,促使反向磁块和磁力块在同一垂直线后停止,通过磁力块和反向磁块同极相斥的原理,可实现减缓电梯箱体下坠速度的功能,解决电梯快速掉落很难使得安全装置能够正常启动的问题。
