Operation principle：When lift car 1 falls to pit, first touch on elastic layer 37, elastic layer 37 is first to electricity
Terraced car 1 play buffering be effect, when lift car 1 downwards fall move down elastic layer 37 and piston 23 when, piston
23 because by the upward effect of a spring 22, filled with gas, the He of 1 extrusion piston of lift car 23 in piston 23 and cylinder 21
During gas in cylinder 21, gas compressed can produce upward thrust to piston 23, so that piston 23 is to lift car 1
Play a part of buffering；When the impact that lift car 1 produces piston 23 is too big, make to be compressed in piston 23 and cylinder 21
Gas produce bigger active force, the elastic diaphragm 26 of the one end of tracheae 25 is burst, and then make the gas of compression through being connected to
Tracheae 25 on the bottom stomata 24 of cylinder 21 is transported at valve 27, makes the spill spin block 29 that is connected on valve 27 in the effect of gas
Under be left on around fix bar 30, enter in space of the gas between valve 27 and tracheae 25 in elastic bag 28, it is and elastic
The gas of original certain volume in air bag 28, when gas compressed enters in elastic bag 28 in piston 23 and cylinder 21,
Elastic bag 28 is big by further support, and until that can contact car, cushioning effect is played to car；And gas is strutted after valve 27
Into elastic bag 28, No. two springs 32 being fixed on valve 27 are retracted, and are produced to the pulling force of valve 27, and No. two springs
32 one end are fixed in fixed seat 33, so that valve 27 resets, valve 27 is closed, and the sealant 34 on valve 27 enters one
Step is prevented to be overflowed outside the gas into elastic bag 28, and elastic bag 28 produces the effect similar to air bag to car
Really, when the lift car 1 is fallen by after the buffering of cylinder 21 again by the buffering of elastic bag 28, and elevator pit
Four edges be mounted on a cylinder 21, each equal transtracheal 25 of cylinder 21 is connected with elastic bag 28, elastic bag
28 are arranged on the middle part of pit, enable the uniform cushioning effect by 4 cylinders 21 when falling of lift car 1, car by
Power is more uniform, further increases the buffering effect of the present invention.
And after 20 use of buffer unit, because the elastic diaphragm 26 in buffer unit 20 has been bursting at the collision, when need change bullet
During property barrier film 26, the collar 35 that spiral is connected to the one end of tracheae 25 can be backed out, good elastic diaphragm 26 is changed on tracheae 25,
The collar 35 is tightened again, good elastic diaphragm 26 is fixed on tracheae 25, and because the collar 35 is provided with perforate 36, thus the collar 35 is simultaneously
The use of elastic diaphragm 26 is not influenceed.
And lift car 1 is when falling to pit, the rubber pneumatic bag 2 on lift car 1 and the elastic layer on buffer unit 20
37 contacts, and compressed air is full of in the rubber ring 9 of rubber pneumatic bag 2, and the upper and lower ends of rubber ring 9 are respectively connected with steel plate 10, rubber
Reinforcement spring 11 is additionally provided with cushion rubber 9, upper and lower side of the two ends of reinforcement spring 11 respectively with rubber ring 9 is fixedly connected, and makes rubber
Air bag 2 has enough intensity, and rubber pneumatic bag 2 also has enough elasticity, when lift car 1 falls to pit, rubber
Air bag 2 can absorb most of impact when lift car 1 hits.
And when rubber pneumatic bag 2 hits pit, the steel plate 10 on rubber pneumatic bag 2 passes to impact microphone by signal is hit
3, and multiple rubber pneumatic bags 2 are provided with the bottom of lift car 1, each rubber pneumatic bag 2 can will hit signal and pass to correspondence
Impact microphone 3；Impact microphone 3 is detonated the igniting agent in igniter 4, so that the gas in gas generator 5
Propellant is mixed, and instantaneously produces a large amount of gases in gas generator 5, substantial amounts of gas is sent to the safety of compression through air inlet pipe 6
In air bag 7, expand the instantaneous time of air bag 7 of compression, and the air bag 7 compressed is arranged in the air bag groove 8 of strip,
Air bag groove 8 is evenly distributed on the inwall of lift car 1, and each air bag 7 is arranged in an air bag groove 8, multiple compressions
Air bag 7 be full of and expanded by a large amount of gas produced in gas generator 5.
And the junction of air inlet pipe 6 and air bag 7 is provided with check valve 12, it is big when what is produced in gas generator 5
Measure gas through air inlet pipe 6 to enter in check valve 12, the bonnet 15 on check valve 12 is opened, after gas enters in air bag 7,
Bonnet 15 is replied by the pulling force effect of back-moving spring 14, closes check valve 12, can not into the gas in air bag 7
Overflow outside；And multiple air bags 7 after expanding are gone out out of each air bag groove 8, multiple classes are formed in lift car 1
Like the device of safe automobile air bag, multiple air bags 7 after expansion support the catch net 16 being arranged on the inwall of lift car 1
Rise, and catch net 16 and elastic plate 17 are fixedly connected through elastic threads 18 with the corner in lift car 1, are opened in air bag 7
Afterwards, catch net 16 and elastic plate 17 are propped up, the personnel being on catch net 16 and elastic plate 17 is not stuck in multiple safety
In gap between air bag 7, make isolation of the personnel through catch net 16 and elastic plate 17 without being contacted with the inwall of lift car 1, lead to
Protective effect of the rubber pneumatic bag 2 to the cushioning effect and air bag 7 of lift car 1 to the personnel in lift car 1 is crossed, and also
By the cushioning effect of buffer unit 20, security of the elevator when falling accident is substantially increased.
