Gravity switch 24 is bridge switch, is powered off state during starting.
Working process and principle of the invention are as follows：When elevator 1 falls, excessively flurried people can be anti-due to instinct
The audio-switch 3 of loud and sharp shout triggering governor circuit should be sent, so as to connect governor circuit, or elevator 1 is sent out
Make trouble thus after when freely falling slogan banner bar be in location of accident 35, the just urgent gravity switch 24 of perpendicular mark post, the quilt of gravity switch 24
Connect, so as to connect governor circuit；Governor circuit connect after, land relay 19 and energy storage lock relay 20 be powered, land after
After the energization of electrical equipment 19 action, landing circuit is connected immediately, and dry ice storage device magnetic valve 13 starts, dry ice storage device locking plate 23
By the adhesive of dry ice storage device magnetic valve 13, the afterbody aperture of dry ice storage device locking plate 23 is located at dry ice storage device shrouding 22
In gas outlet, dry ice is distilled rapidly carbon dioxide gas, and landing air bag 11 is softened, and four landing air bags 11 extrude elevators
Liftway simultaneously produces frictional resistance, slows down the decrease speed of elevator 1；When elevator 1 drops to ground, it is pre- that inserted link 14 inserts ground
The through hole first set, lasso 15 touch ground, and longitudinal spring 9 is compressed, and elevator 1 falls caused gravitional force by longitudinal bullet
Spring 9 is absorbed, and when inserted link 14 continues to glide, after lasso 15 is by energy storage lock position, energy storage locking plate 16 is first compressed, and then energy storage is locked
Piece 16, which resets, opens and pins the gliding direction of lasso 15, and the gravitional force that elevator 1 falls is absorbed by longitudinal spring 9 and switchs to elasticity
Potential energy；Finished when longitudinal spring 9 is pressurized, the gravitional force that elevator 1 falls largely is absorbed, and remaining gravitional force passes through electricity
The up and down motion of terraced bottom plate 7 and crossed strip 8 further buffers, and ensures the safety of the passenger of elevator 1；When elevator 1 takes people
After member's safe escape, manually actuated release-push 10, energy power on circuitry is released, energy storage latching solenoid valve 17 acts, the quilt of energy storage locking plate 16
Suck back, lasso 15 glides, and longitudinal spring 9 discharges the elastic potential energy stored before, and elevator 1 recovers normal condition；Gravity switch shell
Upper limit by row 32, stop position 33, lower limit by row 34 and the location of accident 35 that the right part of body 25 is set are convenient periodically to gravity switch
The detection of device；In addition, when the freely falling body of elevator 1 falls, audio-switch 3 or gravity switch device are due to other reasonses damage
Bad, in the case of not working, enough sobersides can press the subsidiary hand of the present apparatus and press switch 2, connect governor circuit, increase
Add safe probability.
