Description

Technical Field

[0001] The utility model relates to the technical field of intelligent safety elevator alarms, and in particular to an anti-falling intelligent safety elevator alarm device. Background Art

[0002] The anti-fall intelligent safety elevator alarm device is a device used to improve the safety of elevators.

[0003] When the elevator is braked to prevent falling, the anti-fall mechanism is not triggered passively, but requires the personnel inside the elevator to manually turn the handle to start the anti-fall mechanism. However, in reality, when the elevator falls, it is difficult for people to actively turn the handle due to panic, so its design is difficult to meet the actual use needs;

[0004] A Chinese patent (publication number: CN219362904U) discloses an elevator anti-fall mechanism. When the elevator falls due to power failure or other reasons, the electromagnet is passively powered off or the power of the electromagnet is actively cut off by a control button, the electromagnet loses its magnetism, and the electromagnet is separated from the iron block. Under the elastic force of the supporting spring, the brake rod is quickly inserted into the anti-fall brake groove to achieve the purpose of anti-fall braking of the car. The overall process reacts quickly, and can passively achieve anti-fall, which is highly practical.

[0005] In view of the above problems, the existing patent provides a solution. However, the above solution has certain defects during use. When the elevator falls, the brake rod is quickly inserted into the anti-fall brake groove to achieve the purpose of anti-fall braking of the car. However, at this time, the people inside the elevator body are still in a panic and cannot send out alarm information to the outside in time, so that the outside staff cannot receive the distress message in the first time, which may delay the effective rescue time.

[0006] Therefore, an anti-falling intelligent safety elevator alarm device is proposed. Utility Model Content
