Specific embodiment
As shown in Figures 1 to 4, the emergent protector of a kind of collapsible elevator hoistways fall arrest that the present invention is provided, including
Optical inductor, electric switch 2, anti-fall device 3, fixed hinge 4, fixing device and spring 6；The optical inductor is arranged on layer door
On the well enclosure of 7 both sides, it is connected with the electric switch 2, for the detection layers improper open mode of door；Preferably, the light
Electric transducer is picking sensor 1, is installed on the well enclosure of layer door both sides.1 equidistantly installs on one side in picking sensor
There are multiple infrared transmitting tubes, there are the infrared receiving tube of equal number equally arrangement, each infrared transmitting tube in another side accordingly
All to that should have a corresponding infrared receiving tube, and on same straight line.When the infrared transmitting tube on same straight line,
When not having barrier between infrared receiving tube, the modulated signal (optical signal) that infrared transmitting tube sends can smoothly reach infrared receiver
Pipe.After infrared receiving tube receives modulated signal, corresponding internal circuit exports low level, and in the case where there is barrier,
The modulated signal (optical signal) that infrared transmitting tube sends can not smoothly reach infrared receiving tube, and at this moment the infrared receiving tube is received not
To modulated signal, corresponding internal circuit is output as high level.So, can just be examined by being analyzed to internal circuit status
Measure the information of object presence or absence.When car is in non-level position, if layer door is accidentally opened, when people is through layer door,
Picking sensor can detect signal, be transferred to electric switch.
The electric switch 2 is arranged on the well enclosure 8 of 7 both sides of layer door, for receiving the letter that the optical inductor is transmitted
Number and feed back to elevator control cabinet.
The anti-fall device 3 includes framework 301 and the flexible net 302 in the middle of framework, and surrounding framework can be by bending
Part is welded, and center section is fixed by flexible net by framework, and the upper end of the framework 301 is fixed by fixing device, described
It is bolted on framework and magnet is installed, can be attracting with the electromagnet 5.The lower end of the framework is by the fixation
Hinge is fixed；The fixed hinge is used for being fixed on the lower end of framework 301 described in the anti-fall device 3 on well enclosure, institute
Stating framework lower end can rotate around the fixed hinge 4 on perpendicular.
The fixing device is fixed on well enclosure, is connected with elevator control cabinet, and elevator control cabinet can control described
Fixing device is fixed and releases fixation to framework upper end, it is preferable that the fixing device is electromagnet 5, switch board energy
The energization of electromagnet 5 is enough controlled, magnet is installed with the framework 301, can be attracting with the electromagnet 5；It is another
Alternative is that the fixing device is fixture, and the upper end for clamping the framework, switch board can control the opening of fixture
With clamping.
The frame plane is 10 degree with the angle of perpendicular, because framework 301 is inclined, so works as fixing device
For example when electromagnet 5 unclamps 301 upper end of framework, framework can more be accelerated under the double action of self gravitation and the elastic force of spring 6
Speed is rotated down, and launches flexible net 302.
In addition, on relative to the opposite side well enclosure for installing anti-fall device side well enclosure, being provided with lower end magnet 9, institute
Fallen under the framework 301 for stating anti-fall device 3 it is attracting with the lower end magnet 9 during horizontal level, so as to secure the above anti-fall dress
3 are put, a supporting role is played.
Operation principle of the invention is：When car is in non-level position, if layer door 7 is accidentally opened, light curtain is passed
The signal of sensor 1 senses and feeds back to switch board by electric switch 2, and switch board makes car out of service, and makes electromagnet 5
Power-off, loses magnetism, while the spring 6 for being compressed ejects anti-fall device 3, prevents passenger from crashing into hoistway.
Preferred specific embodiment of the invention described in detail above.It should be appreciated that one of ordinary skill in the art
Just many modifications and variations can be made with design concept of the invention without creative work.Therefore, all the art
Middle technical staff's design concept under this invention passes through logical analysis, reasoning, or a limited experiment on the basis of existing technology
Available technical scheme, all should be within the scope of the present invention and/or in the protection domain that is defined in the patent claims.
