Referring to fig. 1 to 4, the preferred embodiment provides an electromechanical interlocking landing door for an elevator, which includes a landing door frame 1, a sliding door body 2, a turning plate 3, a contact swing arm 4 and a limit switch 5.
The landing door frame 1 is installed on a building and is located on a traveling route of the elevator car 12. A floor pedal 13 is arranged on the floor door frame 1 and faces towards the inner side of the building, and a vertical baffle plate 14 is arranged on one side of the elevator.
The push-pull door body 2 is rotatably arranged on the landing door frame 1 and can only be opened towards the inner side of the building.
Two ends of the turning plate 3 are rotatably arranged on the layer door frame 1 and are transversely arranged on the upper edge of the opening side of the push-pull door body 2, and when the turning plate 3 is in a normal laying-down state, the push-pull door body 2 is blocked to be opened; when the turning plate 3 is turned upwards to a horizontal position, the push-pull door body 2 can be freely opened, and the turning plate 3 is provided with a connecting seat 6.
One end of the contact swing arm 4 is rotatably connected to the connecting seat 6, the other end of the contact swing arm is provided with a roller 7 which is in contact with a door lock latch on the elevator car 12, and when the roller 7 is not touched, the turning plate 3 is locked; when the roller 7 is touched, the turnover plate 3 can be freely turned over. Specifically, a stop block 8 is arranged on the layer door frame 1, the contact swing arm 4 is erected on the stop block 8, a spigot 9 is arranged on the contact swing arm 4, when the stop block 8 limits the spigot 9, the turning plate 3 cannot be turned upwards, and the push-pull door body 2 cannot be opened; when the roller 7 is touched, the contact swing arm 4 is jacked up, and the limit of the stop block 8 on the spigot 9 is invalid.
The limit switch 5 is fixed on the layer door frame 1 and located on one side of the connecting seat 6 and linked with the turning plate 3, specifically, a limit groove 10 is arranged on the connecting seat 6, and a swing arm wheel 11 which extends into the limit groove 10 and is linked with the turning plate 3 is arranged on the limit switch 5. The limit switch 5 is in signal connection with the elevator system, and when the turning plate 3 is in a normal laying-down state, the elevator system is electrified; when the flap 3 is in the horizontal position, the elevator system is de-energized.
Every floor all is equipped with electromechanical chain layer door as required, when elevator car 12 moved the floor that needs the floor to stop and stops, and the door lock latch on elevator car 12 and contact swing arm 4's gyro wheel 7 take place the contact, and the concrete expression is that contact swing arm 4 is lifted, and its tang 9 is not restricted by dog 8 and makes the board 3 that turns over can the free rotation, and operating personnel exerts a definite force at this moment and can open for the sliding door body 2.
When the turning plate 3 is turned upwards along with the opening of the sliding door body 2 to the inner side of the building, the limit switch 5 is linked, and the elevator system is powered off, so that the elevator car 12 cannot move up and down, and the safety of personnel entering and exiting is ensured. Only when the sliding door body 2 is closed, the turning plate 3 is reset, and the elevator system can be automatically electrified.
In addition, after elevator car 12 left the floor, contact swing arm 4 was released, and dog 8 is spacing to tang 9 to the restriction turns over 3 upset actions, makes constructor can't open the push-and-pull door body 2 in the building floor, thereby plays safety protection's effect, has also avoided elevator operating personnel to close the incident that the door causes because of forgetting simultaneously.
In conclusion, the electromechanical interlocking landing door for the elevator is simple in structure, convenient to install, safe and reliable, and greatly improves the safety of using the elevator on the site by construction personnel.
The foregoing embodiments are merely illustrative of the principles and features of this invention, which is not limited to the above-described embodiments, but is capable of various modifications and changes without departing from the spirit and scope of the utility model, which are intended to be within the scope of the appended claims. The scope of the utility model is defined by the appended claims and equivalents thereof.
