The invention discloses a high-safety protection device for preventing overspeed and accidental movement of an elevator. The high-safety protection device comprises an elevator shaft, a limiting device and a buffer device, a mounting plate is fixedly connected to the outer wall of the top of the elevator shaft, an elevator car is arranged between the inner walls of the two sides of the elevator shaft, and first sliding grooves are formed in the inner walls of the two sides of the elevator shaft; and the elevator car is slidably connected with the inner wall of the elevator shaft through the arranged first sliding grooves, a traction frame is fixedly connected to the outer wall of the top of the elevator car, first sliding blocks are fixedly connected to the outer walls of the two sides of the traction frame correspondingly, the limiting device comprises a limiting frame, second sliding grooves are formed in the inner walls of the upper side and the lower side of the limiting frame correspondingly, and the outer walls of the first sliding blocks are slidably connected with the inner walls of the second sliding grooves. The high-safety protection device has the beneficial effects that through the arrangement of an electromagnetic device, a clamping block and other devices, a device for controlling a rope to operate is limited, so that the device stops working, the locking effect is improved, the braking distance is reduced, the device has a dual-braking effect, and the braking efficiency is effectively improved.
