Protection device during rapid drop of elevator

Abstract

The invention discloses a protection device during rapid drop of an elevator. The protection device during rapid drop of the elevator comprises the elevator, wherein an elevator car is arranged in theelevator; a ventilation and illumination device is arranged above the elevator car; top protection devices are arranged at the upper sides of the left wall and the right wall of the elevator car; each top protection device comprises first storage cavities which are symmetrically arranged in the upper sides of the left wall and the right wall of the elevator car in a communication manner; a light-transmitting top support plate is rotationally arranged between the front wall and the rear wall of each first storage cavity; and a buffer device is arranged at the lower side of the elevator car, and provides buffer when squatting trapped persons drop and fall to the ground to reduce the damage of impact. The protection device during rapid drop of the elevator can be used as the last protectiondevice in the case of a fault of the elevator; the trapped persons are prevented from being excessively panic due to illumination, ventilation and warning communication, and wait for rescue; if otherprotection devices are failed, the great injury caused to human bodies by an impact force during drop can be reduced, and meanwhile, the elevator is prevented from being deformed to cause extrusion injury to internal personnel, and injury due to the crashing of upper dropping objects is avoided.

Description

technical field [0001] The invention relates to the technical field of elevator protection equipment, in particular to a protection device when an elevator suddenly falls. Background technique [0002] There are many high-rise buildings in the city, and a large number of elevators are widely used. Although the current elevator safety system is quite perfect, there are still elevator falling accidents from time to time, and other safety devices have not failed. And the limited air and communication blockage bring huge panic. When other safety devices of the elevator fail, especially the elevators on high floors, the trapped people have a chance of surviving the damage caused by the huge impact force when they land. It is very small, and the deformation and extrusion damage of the elevator caused by the impact force and the falling objects in the elevator shaft further reduce the possibility of survival, making the elevator falling accident a tragic accident once it occurs. ...
