The invention relates to the technical field of elevators, discloses a safety protection device for an elevator, and solves the current problem that the safety protection measures for the elevator sliding down or rolling down are single and the elevator cannot be effectively prevented from sliding down or rolling down. The device comprises an elevator shaft, wherein both ends of the two side wallsof the elevator shaft are provided with first moving grooves, both sides of the middle of the two side walls of the elevator shaft are symmetrically provided with friction grooves, blocking grooves are provided in the middle of both side walls of the elevator shaft, blocking mechanisms are installed in the middle of the two blocking grooves, three second moving grooves are provided at equal distances on the rear side wall of the elevator shaft, an elevator car is installed inside the elevator shaft, and a moving control mechanism is installed on the top of the elevator car. The elevator has various safety protection measures to prevent sliding down and rolling down, so as to ensure the safety of passengers when the elevator is sliding down or rolling down. At the same time, the safety protection measures of the elevator can effectively prevent the elevator from sliding down or rolling down after starting, so as to increase the safety performance of the elevator.

    本发明涉及电梯技术领域,且公开了一种电梯的安全防护装置,解决了目前对于电梯下滑或溜车的安全防护措施单一,且不能有效的制止电梯下滑或溜车的问题,其包括电梯井,所述电梯井两侧壁的两端均开设有第一移动槽,电梯井两侧壁中部的两侧均对称开设有摩擦槽,电梯井两侧壁的中部均开设有阻挡槽,两个阻挡槽的中部均安装有阻挡机构,电梯井的后侧壁等距离开设有三个第二移动槽,电梯井的内部安装有电梯厢,电梯厢的顶部安装有移动控制机构;本电梯带有多种防止下滑和溜车的安全防护措施,从而在电梯出现下滑或溜车的状况时能够保证乘客的生命安全,同时本电梯的安全防护措施在启动后能够有效的制止电梯下滑或溜车,从而增加了电梯的安全性能。
