The purpose of this utility model is, there is provided a kind of elevator safety air bag buffer.It goes for pit depth
The situation of deficiency is spent, the scope of application is wider, and solves the security hidden trouble that elevator uses in the case of melt pit depth deficiency.
The technical solution of the utility model：A kind of elevator safety air bag buffer, including positioned at car portal frame/knapsack
The airbag buffer of the underbeam bottom of frame, airbag buffer lower section are provided with the feeler lever on elevator hoistways pit；The air bag
Buffer includes computing chip, is connected with gas generator and crash sensor on computing chip, is connected with gas generator
Air bag.
In a kind of foregoing elevator safety air bag buffer, the gas generator includes igniter and aerating agent；Gas
Breather pipe is connected between body generator and air bag.
In a kind of foregoing elevator safety air bag buffer, storage capacitors/battery is also associated with the computing chip.
In a kind of foregoing elevator safety air bag buffer, guard sensor is also associated with the computing chip.
In a kind of foregoing elevator safety air bag buffer, the air bag is externally provided with air bag mounting bracket.
In a kind of foregoing elevator safety air bag buffer, the airbag buffer bottom is provided with indicator lamp.
In a kind of foregoing elevator safety air bag buffer, the feeler lever is located at immediately below crash sensor.
Compared with prior art, the utility model employs similar safe automobile air bag because slow by automatic spring is hit
The method for rushing protective effect, air bag buffer unit is mounted with portal frame/Knapsack-rack underbeam bottom, when car is out of control with pacifying
When the collision of certain dynamics occurs for the feeler lever on elevator hoistways pit, air bag generator will trigger some like low dose
The chemical reaction of explosive charge, the air bag installed in portal frame/Knapsack-rack underbeam bottom will be inflated in moment to be ejected,
Car mitigates impulsive force suffered by car, so as to reach the effect of buffering with playing place mat effect before pit collision.Such peace
Full air bag buffer buffer intensity is bigger, can be suitably used for the situation of well pit depth deficiency, and applicability is more extensive.Its
Secondary, the utility model is additionally provided with guard sensor and storage capacitors/battery, and guard sensor is also referred to as safety collision sensing
Device, it connects with crash sensor, for preventing that it is quick-fried that air bag from missing；The setting of storage capacitors/battery makes power line break in an impact
Line or battery nor affect on air bag normal work in the case of being destroyed, ensure that the stabilization of air bag normal work
Property.In addition, being also associated with indicator lamp on computing chip, indicator lamp display green represents that airbag buffer is in normal work shape
State, show that red expression airbag buffer is in runaway condition.Therefore, the utility model, which has, is applicable to pit depth deficiency
Situation, the scope of application is wider, solves the advantage for the security hidden trouble that elevator uses in the case of pit depth deficiency；And
There are warning, power-off protection and an explosion-proof protection function, security and stability is higher.

Embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment.A kind of elevator safety air bag buffer, form as shown in Figure 1 to Figure 3, including positioned at car gantry
The airbag buffer 4 of the bottom of underbeam 3 of frame/Knapsack-rack, the lower section of airbag buffer 4 are provided with the feeler lever on elevator hoistways pit
5；The airbag buffer 4 includes computing chip 6, and gas generator 7 and crash sensor 15, gas are connected with computing chip 6
Air bag 8 is connected with body generator 7.
The gas generator 7 includes igniter 9 and aerating agent 10；Ventilation is connected between gas generator 7 and air bag 8
Pipe；Storage capacitors/battery 11 is also associated with the computing chip 6；Guard sensor is also associated with the computing chip 6
12；The air bag 8 is externally provided with air bag mounting bracket 14；The bottom of airbag buffer 4 is provided with indicator lamp 13；The feeler lever 5 is located at
Immediately below crash sensor 15.
Operation principle：
The utility model employs similar safe automobile air bag because by the side for hitting automatic spring buffer protection function
Method, air bag 8 is mounted with the bottom of underbeam 3 of portal frame/Knapsack-rack 2, when car 1 is out of control with being arranged on elevator hoistways pit
When feeler lever 5 collides, the collision alarm of the elevator detected will be transferred to computing chip 6, computing by crash sensor 15
Whether collision alarm is analyzed and needs air bag 8 to carry out buffer protection with the critical value multilevel iudge of setting by chip 6.When super
When crossing critical value, the igniter 9 in gas generator 7 ignites igniting agent and produces amount of heat, aerating agent 10 occurs chemical anti-
Should, release nitrogen is decomposed immediately as sodium azide is heated, and is filled with air bag 8 from air-filled pore.Now it is arranged on portal frame/Knapsack-rack
Compressing gasbag 8 in the air bag mounting bracket 14 of the bottom of 2 underbeam 3 inflates ejection at once, and paving is played before car 1 and pit collision
Pad acts on, and mitigates impulsive force suffered by car 1, so as to reach the effect of buffer protection.The air bag of the utility model design delays
The buffering dynamics of flushing device are big, can ensure elevator and the safety of personnel in the case where pit deep is inadequate.Secondly, this practicality is new
Type is additionally provided with guard sensor 12 and storage capacitor/battery 11, and guard sensor 12 is also referred to as safety collision sensor, it with
Crash sensor 15 is connected, for preventing that it is quick-fried that air bag from missing；The setting of storage capacitor/battery 11 make power line break in an impact or
It is that air bag normal work is nor affected in the case that battery is destroyed, ensure that the stability of air bag normal work.Separately
