Background
When the elevator arrives at a landing, the elevator landing door device is driven by the car door device, and the car door and the landing door are linked and then opened for passengers to come in and go out. After the car leaves the flat position, the landing door should be able to close and lock automatically, prevent that the passenger from opening the landing door easily and falling the well. However, sometimes, the landing door is accidentally resisted and cannot be closed in time, so that the elevator cannot run normally. Or in the maintenance period, the user forgets to confirm that the landing door is closed, so that the subsequent accident of falling down the well is caused.
The existing scheme for automatically closing and locking the landing door is to arrange a heavy hammer or a spring and other forced door closing devices on the landing door of the elevator, and when strong wind blows the landing door, the forced door closing devices cannot normally and automatically close the landing door under sudden resistance, so that the landing door is not locked, and the danger of falling down the well is caused.
Another existing scheme for automatically closing and locking the landing door is to use a spring type forced door closing device for the elevator, and because the spring is mechanically fatigued after being used for a long time, the rigidity risks reduction, and it is difficult to detect whether the forced door closing capability of the spring type forced door closing device is obviously reduced during maintenance, which is easy to cause danger in the follow-up process.
