And the elevator out-of-control emergency brake protection device can be manually started in the lift car. The device mainly comprises a bidirectional anchor hook, a sliding trolley, a guide rail bracket, main and auxiliary cables, a main and auxiliary cable tensioning and buffering device, a compound friction speed reducer, a leveling device, a horizontal guide pulley, a vertical guide pulley, a starting hand ring, a stopping ladder, a fixed bracket and the like. When the elevator breaks down and is out of control, and high-speed top rushing or elevator falling danger occurs, elevator passengers in the elevator car immediately pull out the starting hand ring to drive the auxiliary cable to pull the sliding trolley to move towards the stopping elevator on the wall of the elevator shaft, and the two-way anchor hook is hooked to the stopping elevator and pulls the main cable to be in linkage with the compound friction speed reduction device to conduct speed reduction braking on the elevator car. According to the invention, possible fault factors of original components and control programs of an elevator system are completely eliminated, elevator passengers can manually start a braking device in a car to carry out emergency braking self-rescue on the elevator, a pure mechanical structure is not influenced by magnetoelectricity and the like, and the system is independent, simple in structure, safe and reliable.
可在轿厢内手动启动的电梯失控应急制动保护装置。主要由双向锚钩、滑动小车、导轨支架、主副缆绳、主副缆绳涨紧缓冲装置、复式摩擦减速装置、调平装置、水平导向滑轮、垂直导向滑轮、启动手环、阻拦梯、固定支架等组成。在电梯出现故障失控发生高速冲顶或坠梯危险时,轿厢内乘梯人员立即拉出启动手环,带动副缆绳拉动滑动小车向电梯井壁上的阻拦梯移动,双向锚钩钩挂在阻拦梯上并拉动主缆绳联动复式摩擦减速装置对电梯轿厢进行减速制动。本发明完全排除了电梯系统原有构件和控制程序可能出现的故障因素,乘梯人员可以在轿厢内手动启动制动装置来对电梯进行紧急制动自救,纯机械结构不受磁电等影响,系统独立,结构简单,安全可靠。
