Module 312 is received to communicate wirelessly with the wireless transmitter module 15；In the present embodiment, the weight that descending lifeline is born should accord with
The weight demands under elevator cars with full load are closed, because the structure of descending lifeline has been existing, just delay drop without illustrating here
Pull rope can use steel cable used by device.
Fig. 2 is referred to, the air bag component that the inventive method uses has been prior art, the principle of its ignition point inflation
And structure, it is merely just simple to introduce, in figure, the air bag component 4 include cover body 43, the air bag 42 being arranged in cover body 43,
Tertiary circuit plate（It is not shown）And inflation element 41；The inflation element 41 includes electric detonator（It is not shown）, igniting medicinal powder（Not
Diagram）And gas-forming agent（It is not shown）, an ignition media is provided with the electric detonator（It is not shown）, the tertiary circuit plate
The 3rd MCU44 is provided with, the 3rd MCU44 is connected with detonation circuit 45, the second wireless receiving module 46, the detonation circuit
45 are connected with the electric detonator；Second wireless receiving module communicates wirelessly with the wireless transmitter module.When described
When cage 1 is fallen, the protection cushion 11 can effectively prevent the cage from transferring the air bag 42.Described first
MCU and the 2nd MCU, the 3rd MCU are the series of single-chip microcomputer 51.In the present embodiment, above-mentioned lift cylinder 38 can be driven with motor
Mechanism replaces, as long as can realize that safety buckle when being overlapped with pedestal 32, is blocked safety buckle, just no longer illustrated here；
Preferably, wireless receiving module and wireless transmitter module that the present invention uses can use Zigbee wireless modules, due to each
Air bag component and safe buckle assembly are provided with the stair shaft inwall of floor, therefore, can be formed by Zigbee wireless modules
MANET, ensure the stability of wireless network.
The inventive method senses whether cage 1 falls by gyro sensor, is sent when sensing and falling
Signal gives the first MCU, the first MCU to send a signal to wireless transmitter module, wireless transmitter module transmission signal after receiving signal
To the first wireless receiving module and the second wireless receiving module, the first wireless receiving module sends a signal to after receiving signal
Triggering lift cylinder is operated after two MCU, the 2nd MCU receive signal, and lift cylinder carries out step-down operation, now safety buckle
In the presence of torque spring；Safety buckle carries out 180 rotations, and now safety buckle can extend out from opening, so as to safety buckle energy
Hook on the link of cage, now pedestal can glide, and can hold pedestal by descending lifeline, such descending lifeline can enter to cage
Row buffering acts on.
Second wireless receiving module sends a signal to the 3rd MCU after receiving signal, and the 3rd MCU is connected after receiving signal
Detonation circuit, electric detonator is made current flow through, make its heating that the ignition media in electric detonator to be ignited, flame is diffused into igniting immediately
Medicinal powder and gas-forming agent, a large amount of gases are produced, gas enters in air bag 32 after filter screen cools down, and air bag 32 drastically expands, punching
Broken cover body 33, forms barrier, because air bag component is integrally fixed on the inwall of stair shaft, the fixed form can pass through in stair shaft
It is fixed in the punching of stair shaft inwall electric drill；Air bag component can also be embedded in concrete wall, and with rigid metal material
Material rod member is connected with building structure part, ensures that air bag component is solid and reliable.During elevator drops, because air bag is to fill
Gas software, cage effectively can carry out anti-falling buffer work with after balloon contacts, forming extruding in stair shaft to cage 1
With protecting the personal safety of passenger.It is noted that the application air bag is rubber pneumatic bag using the air bag, air bag
Thickness is 1 ~ 2CM, inflates a length of 2M of rear gasbag, a width of 0.5M, a height of：0.5M.Or be made up of nylon cloth, inner surface is covered with
Resin；A length of 2M, a width of 0.5M of rear gasbag are inflated, it is a height of：0.5M.Its 0.5 cubic metre gas, realized and filled by inflation element
Gas, its inflationtime are less than one second, and the air bag can bear 2 ~ 3 tons of weight (rated weight that air bag is born can basis
The fully loaded weight in elevator running railway carriage or compartment is selected, and the material selection of the air bag is prior art, is not just illustrated here.),
The cage of barrier tenesmus enough.
In a word, when gyro sensor of the invention senses cage tenesmus, driving lift cylinder carries out step-down operation,
Now safety buckle is in the presence of torque spring；Safety buckle carries out 180 rotations, and now safety buckle can extend out from opening, from
And safety buckle can be hooked on the link of cage, now pedestal can be glided, and pedestal can be held by descending lifeline, so also can be to electricity
Elevator car carries out cushioning effect；In the present embodiment, the pull rope length of the descending lifeline can be 2.6 meters, can also in high-storey
It is 2.6 ~ 6 meters of length；It can be selected according to the height of floor, so after the pull rope of descending lifeline all pulls out, due to
Descending lifeline is integrally fixed on wall 5, and the fixed form can be locked on wall by drilling, and the pull rope can use steel
Rope, to ensure security.Air bag component is sensing that cage falls, and connects detonation circuit and makes current flow through electric detonator,
Make its heating that the ignition media in electric detonator to be ignited, flame is diffused into the igniting gentle body propellant of medicinal powder immediately, produces a large amount of
Gas.Gas enters in air bag after filter screen cools down, and air bag drastically expands, and breaks through cover body, and barrier, realization pair are formed in stair shaft
Cage carries out anti-falling buffer effect, by Pop-up hook and air bag component, can carry out dual guarantee, protect passenger
Personal safety.
The foregoing is only presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification, it should all belong to the covering scope of the present invention.
