The emergency unlocking assembly 8 is fixed to the corresponding hole at the bottom of the door headboard base plate assembly 1. The roller assembly on the driven hanging plate assembly 3 slides into the inner groove of the guide rail 2. The steel wire rope of the linkage steel wire rope assembly 7 is wound around the driven hanging plate assembly 3. At both ends of the rope wheel, the wire rope fixing bracket 11 is set at the bottom of the middle top plate. The wire rope fixing bracket 11 is fixed to the rope ends of the linkage wire rope assembly 7 by fasteners. The fixing shaft 12 on the linkage wire rope assembly 7 is fixed together with the active hanging plate assembly 4 by nuts. The upper part of the door lock assembly 5 is rotatably set on the active hanging plate assembly 4. The roller assembly on the active hanging plate assembly 4 slides into the inner groove of the guide rail 2. The two ends of the counterweight spring 9 are respectively hooked onto the hook and hook assembly 10 of the driven hanging plate assembly 3. The hook assembly 10 is set at the top bottom of the left side, and the hook is set at the upper right side of the driven hanging plate assembly 3. The switch assembly 6 has a bayonet on the right side, and the active hanging plate assembly 4 has a contact element on the left side. The guide rail 2 is fixed by bolts. At both ends of the door head base plate assembly 1, the middle part of the mounting bracket has a trapezoidal cross-section. The switch assembly 6 is fixed to the door head base plate assembly 1 by bolts and nuts. The wire rope fixing bracket 11 is riveted to the door head base plate assembly 1 by rivets. The driven hanging plate assembly 3 has an inclined plate at the top, and a hook is provided on the inclined plate. The emergency unlocking assembly 8 includes a lock sleeve 20, a triangular lock 21, a lock plate 22, a snap ring 23, and a fixing spring 24. The lower outer wall of the lock sleeve 20 has a recess. The fixing spring 24 is stuck in the recess and fixed to the bottom of the door head base plate assembly 1. The lock sleeve 20 has a triangular lock 21. The upper part of the triangular lock 21 has a mounting block. The mounting block has a mounting hole. The mounting hole of the lock plate 22 is fixed through the mounting hole. The two lock plates 22 are in the shape of... The elevator is vertically mounted. The upper part of the locking plate 22 has a locking hole, the triangular lock 21 has an insertion hole a, and the lock sleeve 20 has an insertion hole b. One end of the retaining spring 23 is locked in insertion hole a, and the other end is locked in insertion hole b. The wire rope fixing bracket 11 is fixed in the middle to the top plate, and both sides of the wire rope fixing bracket 11 are vertically downwards. The wire rope fixing bracket 11 has fixing components. The switch assembly 6 protrudes downwards in the middle, and both sides of the switch assembly 6 are fixed to the top plate. The switch assembly 6 has a locking slot in the middle, and a limiting outer wall is formed on the right side of the middle of the switch assembly 6. The limiting outer wall contacts the wear-resistant block. The hall door sill device is fixed in the elevator shaft by connecting brackets, expansion bolts, etc. When someone in the elevator car presses the button for the corresponding floor, the elevator car will reach the corresponding floor.After the elevator car stops, the door knife arm opens, clamping the two ball bearings on the door lock assembly 5. The moving ball bearings on the door lock assembly 5 then rotate the lock hook downwards, disconnecting the plug assembly on the lock hook from the switch assembly 6 mounted on the door head base plate assembly 1. The motor on the elevator door operator rotates, driving the door knife via a belt, which in turn causes the active mounting plate assembly 4 to slide on the guide rail 2. The linkage steel wire rope assembly 7, fixed to the active mounting plate assembly 4, moves along with it, and finally the driven mounting plate assembly 3 moves with the active mounting plate assembly 4 to the same end. When it reaches the limit position on the rightmost door head base plate assembly 1 and stops, the elevator door is fully open, and the counterweight spring is firmly pulled open, allowing people inside and outside the elevator car to enter and exit freely. When someone inside the car presses the close button or no one outside presses the call button within a certain time, the motor drives the elevator door knife to close, the force acting on the ball bearings of the door lock assembly 5 disappears, and the lock hook on the door lock assembly 5 returns to a horizontal position under its own weight. Simultaneously, the counterweight springs 9, fixed to the hooks of the driven mounting plate assembly 3 and the hook assembly 10 respectively, automatically tighten, thereby driving the driven mounting plate assembly 3 to move to the left. The active mounting plate assembly 4 moves along with it under the action of the linkage wire rope assembly 7. When the contact assembly on the door lock assembly 5 inserts into the switch assembly, the limiting device on the base plate assembly stops. The driven mounting plate assembly 3 and the active mounting plate assembly 4 stop moving. At the same time, the plug assembly on the door lock assembly 5 is also fully in contact with the auxiliary contact assembly, and the circuit is fully connected. After receiving the command, the elevator car moves up and down. When the elevator malfunctions and the door cannot be opened normally or needs maintenance, the emergency unlocking assembly 7 can be turned by using a triangular key. The unlocking rod on the emergency unlocking assembly 7, that is, the lock plate 22, moves the limiting rod through the locking hole, pushing the bolt of the door lock assembly 5, thereby lifting the lock hook downward. The outer wall of the lock hook is arc-shaped, so it smoothly engages with the locking slot. When the lock hook is lifted downward, the elevator doors on both sides can be opened by gently pulling them with your hands from the outside of the car.
