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.
