An elevator top collision prevention structure comprises a rope clamping device with a rope clamping block, a traction machine power source toggle switch connected with a traction machine power source and provided with a switch deflector rod and a toggle mechanism, and the toggle mechanism comprises a toggle rod used for toggling the switch deflector rod and a toggle frame used for installing the toggle rod in a sliding mode. The poke rod comprises a sliding main body part and a poke part connected with the sliding main body part; the pull rope is connected with the rope clamping block and the poke rod, and the guide assemblies are matched with the pull rope. According to the device, the rope clamping mechanism is arranged to control a traction machine switch, after the rope clamping mechanism clamps a steel wire rope, a traction wheel does not output power to an elevator, then the top rushing prevention capacity of the device is further improved, and the safety of the elevator is further improved. The anti-roof-rushing capacity is good, and transformation of the elevator with the small machine room is facilitated.

    一种电梯防冲顶结构,包括具有夹绳块的夹绳器、和曳引机电源相连接的具有开关拨杆的曳引机电源拨动开关、拨动机构,拨动机构包含用于拨动所述开关拨杆的拨动杆、用于滑动安装所述拨动杆的拨动架,拨动杆包含滑动主体部、和所述滑动主体部相连接的拨动部;还包括连接所述夹绳块与拨动杆的拉绳以及和拉绳配合的若干导向组件。本发明,通过设置夹绳机构控制曳引机开关,在夹绳机构夹住钢丝绳后,能够使曳引轮不在给电梯输出动力,进而进一步的提高了本装置的防冲顶能力,进一步的提高了电梯的安全性。本发明,防冲顶能力好且利于小机房电梯的改造。
