Abstract

AN EMERGENCY BRAKING DEVICE IS USED FOR A PASSENGER CONVEYOR INCLUDING A GEAR UNIT IN WHICH A SPROCKET (5) AROUND WHICH A FOOTSTEP CHAIN (6) HAVING A PLURALITY OF FOOTSTEPS (7) ATTACHED THEREONTO IS WOUND AND A SPROCKET (3) AROUND WHICH A DRIVE CHAIN (4) THAT TRANSMITS POWER FROM A MOTOR (1) IS WOUND ARE FIXED TO THE SAME ROTATION SHAFT (8). THIS EMERGENCY BRAKING DEVICE INCLUDES: A RATCHET (14) FIXED TO THE ROTATION SHAFT (8); A BRAKING HOOK (17) THAT BRAKES ROTATION OF THE RATCHET (14); AN OPERATION LEVER (16) THAT SUPPORTS THE BRAKING HOOK (17) AT A POSITION APART FROM THE RATCHET (1 4); A DETECTION UNIT (11) ROTATABLY SUPPORTED IN A CASE WHERE SLACK OR CUT OCCURS IN THE DRIVE CHAIN (4); AND A WIRE CORD (15) THAT COUPLES THE DETECTION UNIT (11) AND THE OPERATION LEVER (16) TO EACH OTHER. IN A CASE WHERE THE DETECTION UNIT (11) MAKES ROTATION, THE ROTATION OF THE DETECTION UNIT (11) IS TRANSMITTED TO THE OPERATION LEVER (16) THROUGH THE WIRE CORD (15). THEN, THE BRAKING HOOK (17) IS RELEASED FROM THE SUPPORT MADE BY THE OPERATION LEVER (16), AND BRAKES THE ROTATION OF THE RATCHET (14).
