Detailed Description
The invention is further described below with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, the elevator door vane device shown in the figure comprises a bottom plate 13, a connecting rod 4 and a connecting rod 7 are axially arranged on the bottom plate 13, and two ends of the connecting rod 4 and two ends of the connecting rod 7 are respectively hinged with a pair of vane arms 5 and 6. The link 4 moves to drive the pair of knife arms 5, 6 to open and close.
The slide block 1 is arranged on a bottom plate 13 in a sliding way through a guide rod 2, the slide block 1 is driven to move by a belt mechanism (not shown in the figure) in the gantry crane and drives a pair of knife arms 5 and 6 to move through a connecting rod 4; the guide rod 2 is provided with a spring 15 for driving the slider 1 to move.
A limiting component 8 used for limiting the position of the sliding block 1 is arranged on the sliding block 1, and a trigger plate 9 matched with the limiting component 8 is installed on a bottom plate of the gantry crane.
The utility model is characterized in that: the door vane lock further comprises a swing rod 3, a door vane lock hook 10, a fixed lock hook 11 and a rescue rope assembly 12. The swing rod 3 is hinged on the sliding block 1, and the swing rod 3 is driven by the connecting rod 4 to move. The door knife lock hook 10 is in driving connection with the swing rod 3, and a fixed lock hook 11 which is matched with the door knife lock hook 10 and used for locking the door is arranged on a bottom plate of the door machine. A rotating lever 12a in the rescue rope assembly 12 is axially provided on the bottom plate 13.
The working principle of the utility model is as follows:
referring to fig. 2, when the door is opened, the motor applies force to drive the sliding block 1 through a belt mechanism in the door machine, and the sliding block 1 moves horizontally due to the guide of the guide rod 2 to drive the connecting rod 4 to rotate. The rotating connecting rod 4 drives the knife arms 5 and 6 to open. Hall balls 14 are encountered during deployment of the knife arms 5, 6, and the hall balls 14 provide a door opening restricting force to the knife arms 5, 6 and the links 4, 7. After the knife arms 5 and 6 are blocked from opening the door, the swing rod 3 is shifted through the connecting rod 4 to enable the swing rod 3 to swing, the swing rod 3 swings to open the door knife lock hook 10, and the door knife lock hook 10 is separated from the fixed lock hook 11. At this moment, the position of the sliding block 1 is limited by the limiting component 8, and the door machine opens the door smoothly.
When the leveling is powered off, the spring 15 on the guide rod 2 provides elastic force to drive the sliding block 1 to horizontally open, and the sliding block 1 drives the connecting rod 4 to rotate. The rotating connecting rod 4 drives the knife arms 5 and 6 to be opened, and at the moment, the car door and the landing door are in the door opening state, so that people can safely evacuate.
Referring to fig. 3, when the door is closed, the motor applies force, the limiting assembly limits the slider 1 to move in the reverse direction, and the belt mechanism drives the whole door knife to move in the door closing direction. When the door is closed, the trigger plate 9 triggers the limiting component 8, the limiting component 8 is separated from the clamping groove 1a of the sliding block 1, the sliding block 1 moves horizontally under the driving of the belt mechanism, at the moment, the sliding block 1 drives the swing rod 3 to move, and the swing rod 3 drives the connecting rod 4 to rotate. The connecting rod 4 rotates to drive the knife arms 5 and 6 to be folded, the knife arms 5 and 6 are separated from the hall ball 14, and the door knife lock hook 10 falls into the fixed lock hook 11 to close the door in place. If the elevator runs to the non-flat floor and is abnormally stopped, a person takes the door in the car at the moment, the door knife locking hook 10 and the fixed locking hook 11 can be mutually occluded to limit the door to be opened, and the safety of passengers is protected.
Referring to fig. 4, when the elevator stops in a non-flat-bed state due to an abnormal state, due to the anti-theft reason, a person in the car cannot open the car door, at this time, a professional needs to rescue the person, after the person opens the landing door triangular lock and opens the landing door, the rescue rope 12b in the rescue rope assembly 12 is pulled, the rotating rod 12a in the rescue rope assembly 12 rotates, the door knife locking hook 10 is pulled to be opened upwards, the fixed locking hook 11 is separated, and the person in the car can be rescued by opening the car door by the rescue person on the side of the landing door.
