Description

Technical Field

[0001] The utility model relates to an anti-collision device for an elevator hall door and belongs to the technical field of elevator equipment. Background Art

[0002] At present, there are more and more high-rise buildings, and the frequency of elevator use is also increasing. However, due to various reasons, the elevator hall door may collide with other objects during operation, causing personal injury or damage to the elevator equipment. Therefore, an effective anti-collision device is of great significance. After searching, it was found that the Chinese patent with publication number CN212475734U disclosed an anti-collision safety elevator door. In this patent, the first anti-collision strip and the second anti-collision strip can block the rubber strip in advance before closing the elevator door, reducing the visual effect of the elevator door gap being too large, and preventing someone from forcibly colliding with the elevator door. When the electric push rod pushes the first anti-collision strip and the second anti-collision strip to move inward, the infrared photoelectric sensor will be recovered into the groove respectively when sensing the contact between the first anti-collision strip and the second anti-collision strip, and then close the elevator door. In addition, when the first anti-collision strip and the second anti-collision strip are hit by a person, the elevator door will not be closed further, thereby reducing the damage caused to the elevator door by the person who hits. The rubber stick can be automatically restored, reducing maintenance costs. However, this patent only prevents the crowd from colliding with the elevator, and does not provide effective protection against the impact of large cargo on the elevator hall door.
