Angle is 360 degree, door cutter motor 10 rotating 360 degrees, and the second synchronous pulley 6 revolves turnback.
Door cutter motor 10 and the first contact switch 14 and the second contact switch 17 are electrically connected to the controller of elevator, control
Device is that elevator is existing, and generally PLC does not repeats them here.Controller is by receiving the berthing signal of car and gate and layer
The shutdown signal of door controls a duty for cutter motor 10, and by receiving the first contact switch 14 and the second contact switch
The signal of 17 controls opening and the operation of car of gate and layer door respectively.
Operation principle of the present invention is as follows:
After car rests in a certain stop, controller turns around to door cutter motor 10 signal, door cutter motor 10 action, rotation,
Eccentric shaft 31 rotates 0.5 circle.Swinging guide rails 22 is pushed away to gate direction rotary oscillation, door cutter 26 around the bearing pin center of its right
Go out.Meanwhile, driving arm 4 drive connection bar 15 to move, connecting rod 15 drives left and right pin block 3,21 to stretch out simultaneously.Stretch out rear left and right
Pin block 3,21 be respectively protruding into correspondence upper and lower block 30,29 between gap in, car be locked in upper and lower block 30,29 it
Between.Now, the first contact switch 14 closes, and gate motor receives opening signal, and gate is opened with layer door.
If now car surprisingly moves up, left and right pin block 3,21 is stoped by upper block 30, it is impossible to mobile；If sedan-chair
Railway carriage or compartment surprisingly moves down, and left and right pin block 3,21 is stoped by lower block 29, it is impossible to mobile.Guarantee will not slip ladder phenomenon, therefore
The personal safety of passenger is secure.
Passenger is upper and lower complete, and after gate is closed with layer door, door cutter motor 10 starts rotation and turns around, and eccentric shaft 31 revolves again
Turn 0.5 circle.Swinging guide rails 22 rotates in the opposite direction around the bearing pin center of right, and door cutter 26 is regained.Meanwhile, arm 4 is driven to drive even
Extension bar 15 moves, and connecting rod 15 drives left and right pin block 21 to return simultaneously.Left and right pin block 3,21 departs from upper and lower block 30,29.With
Time, the second contact switch 17 closes, and controller receives signal rear drive cage operation.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
