Detailed description of the invention
By reference to the accompanying drawings the present invention is described in further detail below by embodiment.
As shown in Figure 1, apparatus of the present invention comprise anti-falling railing unit 11 and acquisition of signal and alarm unit 12; Anti-falling railing unit 11 comprises lift car travel switch 1, controls electromagnet 2 and anti-falling railing 3, and acquisition of signal and alarm unit 12 comprise microprocessor 4, limit switch 5, coder 6, decoder 7, annunciator 8, DC regulated power supply 9 and ann reset switch 10; Lift car travel switch 1 detects lift car whether flat bed, and is controlled by the mode of operation controlling electromagnet 2 pairs of anti-falling railings 3; Anti-falling railing 3 is connected with limit switch 5, and limit switch 5 is connected with microprocessor 4 by coder 6, and microprocessor 4 is connected with annunciator 8 through decoder 7, and ann reset switch 10 is connected with microprocessor 4; DC regulated power supply 9 provides working power for giving acquisition of signal and alarm unit 12.
As shown in Figure 2, anti-falling railing 3 comprises body of rod 3-1, pulley 3-2, armature 3-3, release spring 3-4 and hinge 3-5, body of rod 3-1 transfers along the second fan elevator door side notch 14-1 under the effect of release spring 3-4 and self gravitation when lift car breaks down non-flat bed, thus block passenger and enter elevator, prevent passenger to fall hoistway.Pulley 3-2 is contained in body of rod 3-1 top, makes body of rod 3-1 can fan elevator door side notch 14-1 smoothly movement along second; Armature 3-3 is fixed on body of rod 3-1, holding body of rod 3-1, making anti-falling railing 3 be fixed in the first fan elevator door side notch 13-1 when controlling the coil electricity of electromagnet 2; One end of release spring 3-4 is fixed in the first fan elevator door side notch 13-1, and the other end is fixed on body of rod 3-1, when control electromagnet 2 is not energized, body of rod 3-1 is reliably transferred under its elastic force effect.Hinge 3-5 is used for fixed core 3-1, and body of rod 3-5 freely can be rotated around it.
As shown in Figure 3, be the lateral plan of the first fan elevator door 13, when the degree of depth of the first fan elevator door side notch 13-1 can ensure that anti-falling railing 3 is fixed on this notch inside, anti-falling railing 3 does not expose outside the first fan elevator door sidepiece end face 13-2.
As shown in Figure 4, it is the lateral plan of the second fan elevator door 14, second fans elevator door side notch 14-1 when anti-falling railing 3 is transferred for pulley 3-2 provides the track of slip, stopper 14-3 is for stopping the further downslide of anti-falling railing 3, stopper 14-3 is disposed across between two elevator doors with certain positive pitch making anti-falling railing 3, passenger is prevented to be strayed in elevator when elevator faults, recover normal at elevator simultaneously, when elevator door cuts out automatically, anti-falling railing 3 can be fanned elevator door side notch 14-1 upward sliding along second and be retracted in the first fan elevator door side notch 13-1 under the promotion of elevator door.
Control the part sectional view that electromagnet 2 is connected with anti-falling railing 3, as shown in Figure 5, controlling electromagnet 2 is loaded in the first fan elevator door side notch 13-1, comprise coil 2-1, iron core 2-2 and armature 3-3, wherein armature 3-3 is fixed on the body of rod 3-1 of anti-falling railing 3, whether the control signal control anti-falling railing 3 that controlling electromagnet 2 provides according to lift car travel switch 1 transfers, thus prevents passenger to be strayed in elevator when elevator faults.
Lift car travel switch 1 is for providing the signal of lift car whether flat bed, and when the normal flat bed of lift car, lift car travel switch 1 closes; Otherwise lift car travel switch 1 disconnects.
Limit switch 5 is loaded in the first fan elevator door side notch 13-1, and limit switch 5 is connected with coder 6, and the position signal for detecting anti-falling railing 3 sends coder 6 to and encodes.Consider that skyscraper floor is more, if directly send the output signal of each floor limit switch 5 to microprocessor 4, then the I/O quantity of microprocessor 4 not, may send microprocessor 4 to after adopting the output signal of coder 6 pairs of limit switches 5 to encode for this reason again.
Annunciator 8 is connected with decoder 7, and when lift car breaks down non-flat bed, microprocessor 4 sends the annunciator 8 that alerting signal controls Control Room and designated floor after decoder 7 decoding and reports to the police.
Principle of work of the present invention is as follows:
When the normal flat bed of lift car, lift car travel switch 1 closes, control electromagnet 2 to be energized, the electromagnetic attraction produced holds the armature 3-3 be fixed on anti-falling railing 3, anti-falling railing 3 is fixed in the first fan elevator door side notch 13-1, does not affect passenger when elevator door is opened and normally to come in and go out elevator; And when lift car is not when sending that one deck of flat bed instruction but elevator door is opened, lift car travel switch 1 does not close, control electromagnet 2 power-off, anti-falling railing 3 is smoothly transferred along the second fan elevator door side notch 14-1 under the elastic force of release spring 3-4 and the effect of self gravitation with opening of elevator door, thus block passenger and enter elevator, prevent passenger from causing the event of the hoistway that falls to occur because carelessness is strayed into elevator; When anti-falling railing 3 leaves the first fan elevator door side notch 13-1, limit switch 5 action, the encoded device 6 of its on-off signal produced sends microprocessor 4 to after encoding, microprocessor 4 receives this signal and send alerting signal after respective handling, and the annunciator 8 that this alerting signal controls Control Room and designated floor after decoder 7 decoding is reported to the police.
The present invention can prevent because break down non-flat bed and elevator door of lift car opens by mistake the accident that the personnel that may cause crash into elevator hoistways and occur by arranging anti-falling railing 3.The present invention has the advantages such as structure is simple, low cost of manufacture, real-time, safety is good.
