On wheel 8 or the extended line at 10 center of the second driven wheel, at this point, angle when the second connecting rod 13 is located at highest order and lowest order is
A2, according to sine,
Wherein, two unknown numbers of only A2 and X, can find out.
But since gate 1 is moved in glide direction, and the length of the length of first connecting rod 12 and the second connecting rod 13
It is constant, so sliding block 6 allows for moving in sliding slot 5 along glide direction.In conjunction with sliding block 6 in 1 length direction of gate
Movement, sliding slot 5 are arranged in sine curve, and sinusoidal amplitude is X/2.Assuming that the first driven wheel 8 and the second driven wheel 10
Radius be R, then in one cycle, the moving distance of gate 1 is 2*pi*R, is embodied on sine curve the i.e. week of the curve
Phase T=2*pi*R, if 1 length direction of gate is the longitudinal axis, then the sinusoidal formula using 1 moving direction of gate as horizontal axis

It is connect with 2 signal of controller.When connecting rod 16 is moved at enabling limit switch 19,1 stop motion of gate；When connecting rod 16 is moved
It moves to the shutdown limit switch 20,1 stop motion of gate.And in order to improve the safety of elevator, after elevator door is closed,
Speed is slower and slower, i.e., when connecting rod 16 is moved at First Speed switch 21, First Speed switch 21 issues signal to control
Device 2 slows down 1 movement speed of gate；When the connecting rod 16 is moved at second speed switch 22, second speed switch 22
Issuing signal to controller 2 slows down 1 movement speed of gate again.
The course of work is as follows:
When 1 open state of gate, if there is barrier to be placed on check frequency, transmitter 3 and receiver 4 can't detect barrier
Hinder object, variable-frequency motor 7 drives gate 1 mobile at this time, transmitter 3 and receiver 4 is moved along sliding slot 5, when first
Driven wheel 8 and the second driven wheel 10 turn over a cycle, transmitting tube and reception pipe can scanned check frequency, reach elimination
The purpose of blind area, in this process, if having detected barrier, then the reversion of variable-frequency motor 7 again opens door；
In addition, when transparent barriers object be placed on gate 1 it is intermediate when, with the closing of gate 1, detection sensor is respectively to two
Side is mobile, can be with there are one the distance of gate 1 as long as the mobile distance of both sides gate 1 is added the distance of an at most gates 1
Buffering, has the function that anti-pinch；When transparent detection sensor 14 has detected transparent barriers object, controller 2 is outputed signal to
Turn again to open door to control motor hair.
