(4) counter weight strip below curtain face is forward and backward, wirerope and fixed ring, turnbuckle are used in lower section three directions respectively
Tighten being straightened, corrective weight item entirety straightness, can prevent in this way because caused by counter weight strip is too long and self gravity from
Curtain face caused by so sagging and bending is uneven；
(5) protruding parts are equipped with above curtain face, when decline inductive switch senses this position, motor control main shaft stops
Rotation, curtain face stops decline at this time, to guarantee safety in utilization；
(6) main shaft left support seat is equipped with chain inductive switch, for detecting chain, when chain breakage, and inductive switch
Control system is sent a signal to, control system controls motor stalls, while electric pushrod pushes forward stop bit bolt, only
Position bolt is inserted into the space formed by four second bearings, prevents main shaft from continuing to rotate, to guarantee using safe.Stop bit
Bolt front end is equipped with bearing, avoids that dieback situation just occurs with second bearing linear state when travelling forward, it is ensured that only
Position bolt can be inserted into；
(7) first frames are switched equipped with upward stroke, when left fixing seat rises contact upward stroke switch, switch hair
Signal is to control system out, and control system controls motor stalls, and curtain face stops rising, to guarantee safety in utilization.
