Embodiment
As shown in Figures 1 to 4, the emergent protection dress of a kind of Telescopic shaft type elevator hoistways fall arrest provided by the utility model
Put, including optical inductor, electric switch 1, expansion link 2, protection network 3 and fixing device；The optical inductor is arranged on 8 liang of layer door
On the well enclosure 9 of side, for the improper open mode of detection layers door；Preferably, the optical inductor is picking sensor 6, quilt
On the well enclosure of layer door both sides.Multiple infrared transmitting tubes, another side phase are equidistantly installed on one side in picking sensor 6
The infrared receiving tube for having identical quantity equally to arrange answered, each infrared transmitting tube are corresponding with a corresponding infrared receiver
Pipe, and on same straight line.When there is no barrier between the infrared transmitting tube on same straight line, infrared receiving tube
When, the modulated signal (optical signal) that infrared transmitting tube is sent can smoothly reach infrared receiving tube.Infrared receiving tube receives modulation
After signal, corresponding internal circuit exports low level, and in the case where there is barrier, the modulated signal that infrared transmitting tube is sent
(optical signal) can not smoothly reach infrared receiving tube, and at this moment the infrared receiving tube does not receive modulated signal, corresponding internal electricity
Road output is high level.So, the information of object presence or absence is detected by carrying out analysis can to internal circuit status.
When car is in non-level position, if layer door is accidentally opened, when people passes through layer door, picking sensor can detect signal,
It is transferred to electric switch 1.
The electric switch 1 is arranged on the well enclosure of layer door both sides, for receiving the signal that the optical inductor transmits
And feed back to elevator control cabinet.
The fixing device is arranged on well enclosure, is connected with elevator control cabinet, elevator control cabinet can control described solid
Determine device and be fixed and release fixation to expansion link lower removable end 202；Preferably, the fixing device is electromagnet 7,
Elevator control cabinet manipulates whether electromagnet has magnetic by controlling electromagnet whether to be powered, always to expansion link lower removable
End 202 is fixed and released fixation；As another scheme, the fixing device is fixture, described flexible for clamping
The lower removable end 202 of bar, switch board can control opening and the clamping of fixture by electrification.
The expansion link 2 includes top fixing end 201 and lower removable end 202, and the top fixing end 201 is fixed on
On well enclosure, during elevator normal operation, the lower removable end 202 of the expansion link 2 is fixed by fixing device holds, and layer door is anon-normal
When often opening, lower removable end 202 extends downwardly under self gravitation effect；One end of the protection network 3 is fixed on well enclosure
On, the other end is fixed on the expansion link lower removable end, and when when bottom, movable end extends downwardly from, the protection network is opened up
Open.
Advantageously, in addition to spring 5, the spring are located in the guide pipe 4, the top fixing end position of the expansion link
In the inside of the spring, i.e. top fixing end 201 passes through the inside of spring 5, and during elevator normal operation, spring 5 is in compression
State, during the improper opening of layer door, lower removable end 202 extends downwardly under spring 5 and self gravitation effect.By increasing bullet
Spring, make the speed that protection network falls faster.
Advantageously, on the both sides well enclosure of layer door lower end, lower end magnet is installed, during the improper opening of layer door,
Lower removable end extends downwardly under self gravitation effect, extends to and lower end magnet is attracting contacts, so that protection network
It is fixed after expansion, is unlikely to rock.
