Description

Technical Field

[0001] The present invention relates to the technical field of box elevators, and in particular to an intelligent locking and mis-opening prevention device for a box elevator door. Background Art

[0002] Elevators play an indispensable role in people's lives. As a special equipment, the safety of elevators has received great attention, but elevator failures still occur from time to time. Among elevator accidents, elevator hall door failures account for a large proportion. The car has not reached the current floor and the hall door is open, or the elevator is under maintenance and no warning measures are taken at the hall door. In addition, the hall door may be opened abnormally due to external forces, which may eventually lead to disasters.

[0003] The door locks of the currently used cabin elevators are not stable enough when opening and closing the doors, and the elevator doors are easily opened by mistake, causing casualties and economic losses. It is necessary to strengthen the anti-misopening capability of the elevator doors to avoid possible situations and bring adverse effects.

[0004] For example, a device for preventing elevator hall door from opening by mistake disclosed in the Chinese invention patent publication number CN206051243U includes a controller, a car and a hall door; the device is characterized in that it also includes a locking mechanism, the locking mechanism is located between the hall door and the car, and locks the hall door under the control of the controller; a sensing device for determining the position of the car is provided on the side of the car facing the hall door and the relative position on the hall door, and the sensing device is electrically connected to the controller; the locking mechanism includes a driving device, a clamping member and a limiting body, and the clamping member cooperates with the limiting body under the drive of the driving device to lock the hall door. The device can effectively prevent the elevator hall door from opening by mistake and ensure the safety of elevator passengers and maintenance personnel.

[0005] However, the locking method of the elevator door of the above device is relatively simple, and it is not possible to strengthen the locking of the elevator door well. The locking mechanism is not strong enough and may be opened by mistake.

[0006] To this end, we propose an intelligent locking and anti-misopening device for cabin elevator doors to solve the above problems. Summary of the invention
