The invention discloses a brake failure protection elevator. The brake failure protection elevator comprises an elevator shaft, wherein a working cavity is formed in the elevator shaft, an elevator is arranged in the working cavity in an up-down sliding mode, an elevator fixed pulley is installed at the upper end of the elevator, a driving motor is fixedly arranged at the upper end of the elevator shaft, a motor rotating shaft is rotatably arranged at the front end of the driving motor, and an installation frame is fixedly arranged at the upper end of the elevator shaft. When an elevator brake fails or a steel cable on a balancing weight is broken, the elevator starts to fall, meanwhile, the sliding speed of the steel cable is increased, a traction disc is driven to rotate rapidly, a protection device is automatically started, a brake jamming tooth is automatically lifted to jam the traction disc, continuous rotation of the traction disc is limited, meanwhile, a second brake pad automatically stretches out, and the steel cable is jammed on the traction disc which is jammed and static, so that the elevator is prevented from continuously falling, and the life safety of passengers in the elevator is guaranteed.
本发明公开了一种刹车失效保护电梯,包括电梯井,所述电梯井中设有工作腔,所述工作腔中上下滑动设有电梯,所述电梯上端安装设有电梯定滑轮,所述电梯井上端固定设有驱动电机,所述驱动电机前端旋转设有电机转轴,所述电梯井上端固定设有安装架,在遇到电梯刹车失效或者配重块上钢索断裂的情况时,电梯开始下坠,同时钢索的滑动速度加快,带动牵引盘快速旋转,保护装置自动启动,自动升起刹车卡齿卡死牵引盘,限制牵引盘继续旋转,同时自动伸出第二刹车片,将钢索卡死在已经卡死静止的牵引盘上,防止电梯继续下坠,保障了电梯内乘客的生命安全。
