External boundary bottom, is installed parallel to elevator car bottom, and one layer of plenum space, plenum space difference are also set up outside elevator car
There is connector in bottom and upper air bag group, lower gasbag group, gas tank bottom also sets up airway tube, control valve is set above airway tube
Door；
Rubber layer is additionally provided with outside the elevator car both sides, both sides set respectively in the plenum space parallel with rubber layer
One electromagnet and the second electromagnet, wherein the second electromagnet passes through wire and the standby electronic box for being arranged on elevator car inside top
Connection.Inductor（It is arranged to acceleration transducer, inductor is additionally provided with wire and the control valve of gas tank connects.Airway tube
T shape is arranged to, T-shaped bottom is connected to above gas tank, and two side branch are arranged on plenum space top.Elevator car inside top
Stand-by lamp is also equipped with, stand-by lamp is connected by wire with standby electronic box.Inductor is also connected with standby electronic box by wire.
The present invention has advantages below：：For elevator in daily operation, the acceleration of operation is general all smaller.But
When elevator tenesmus out of control, acceleration of gravity will increased dramatically, now gravity acceleration sensor its detect that gravity adds
Speed exceedes early warning threshold values, then sends a signal for exceeding early warning threshold values from gravity acceleration sensor to control module.Gas
Capsule module is made up of gas generator and air bag, and control module sends work order to gas generator, from gas generator to
Fast aeration in air bag, so that air bag quickly launches opening.Speed of the elevator car when falling has been buffered, has been reduced anti-
Shake the danger triggered.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
In figure：1- lower gasbag groups, the upper air bag groups of 2-, 3- side walls, 4- elevator cars, the electromagnet of 5- first, the electromagnet of 6- second, 7-
Rubber layer, 8- plenum spaces, 9- gas tanks, 10- control valves, 11- airway tubes, 12- inductors, the standby electronic boxs of 13-.
Embodiment
The present invention will be further described below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to following institute
State.
As shown in figure 1, a kind of electromagnetism gasbag-type elevator protection device, it includes elevator car 4, upper air bag group 2, lower gasbag
Group 1, gas tank 9, inductor 13, standby electronic box 13, the gas tank 9 are arranged at the outside upper right corner of elevator car 4, by riveting branch
Frame is fixed on above elevator car 4, and inductor 12 is riveted on the left upper of elevator car 4 by support, and upper air bag group 2 is arranged on
Below the bottom plate of elevator car 4, fine crack is being internally provided with elevator car 4, it is extraneous that lower gasbag group 1 is arranged on elevator car 4
Bottom, installed parallel to the bottom of elevator car 4, the both sides of elevator car 4 also set up side wall 3, and the outside of side wall 3 sets one layer of inflation empty
Between 8, plenum space 8 has connector in bottom and upper air bag group 2, lower gasbag group 1 respectively, and the bottom of gas tank 9 also sets up airway tube 11,
Airway tube 11 sets control valve 10 above；
The outside of the both sides of elevator car 4 is additionally provided with rubber layer 7, and both sides are distinguished in the plenum space 8 parallel with rubber layer 7
