Elevator accident protection device

Abstract

The invention discloses an elevator accident protection device. The elevator accident protection device comprises an elevator, a detection mechanism, a speed reducing mechanism and a buffering and vibration reducing mechanism, wherein a safety lock and a clamping column are arranged on the elevator, the safety lock achieves the effect that when the elevator falls rapidly, a movable bolt in the safety lock can clamp an elevator door, so that the elevator door cannot be opened, the clamping column and a clamping block are used in cooperation, the detection mechanism is installed on the side face of the elevator and achieves the effect of automatically starting the protection device when the elevator falls abnormally and rapidly, the speed reducing mechanism is installed on the side face of the elevator and achieves the effect of reducing the falling speed of the elevator when the elevator falls abnormally and rapidly, the buffering and vibration reducing mechanism is installed below the elevator, the impact force generated when the elevator falls is relieved through the buffering and vibration reducing mechanism, and the elevator cannot bounce repeatedly.

Description

technical field [0001] The invention relates to the technical field of elevator safety, in particular to an elevator accident protection device. Background technique [0002] With the continuous increase of floors, the use of elevators has become more and more common, and safety accidents occur frequently during the use of elevators. At present, the safety protection devices of elevators mainly include traction machine brakes, speed limiters, and safety gears. , rope clamp and other safety protection devices. However, despite the installation of numerous safety protection devices, for any single component failure and traction condition damage of the drive host or drive control system that the car relies on, the wire rope slips on the traction sheave, causing the car to leave the landing accidentally Moving, still can cause the generation of vicious accident that elevator shears and cause death, seriously threatens the personal safety of the masses. Therefore, it is necessa...
