The invention provides an anti-falling elevator and a control method thereof. The anti-falling elevator comprises sliding rails vertically arranged and an elevator cab body slidably connected with thesliding rails. Sliding blocks adaptive to the sliding rails are arranged on the elevator cab body, extension and retraction devices are arranged on the sliding rails, and the extension and retractiondevices are used for extending into the sliding rails and stopping the sliding blocks when the rate of descent of the elevator cab body is larger than predefined threshold value to prevent the elevator cab body from descending. A speed sensor is arranged on the outer side of the sliding rails, and the speed sensor is connected with the extension and retraction devices and used for detecting the rate of descent of the elevator cab body. Air bags are arranged in the elevator cab body, and the air bags are connected with the speed sensor and open when the rate of descent of the elevator cab bodyis larger than the predefined threshold value. The anti-falling elevator can prevent the elevator falling when the elevator falls accidentally, protect the safety of elevator passengers, and safe airbags are further arranged to prevent someone from being injured.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to an anti-fall elevator and a control method thereof. Background technique [0002] With the increase of high-rise buildings, the use of elevators is also increasing. At present, the safety problem of elevators has not been significantly improved, especially for high-rise elevators. When the car runs to a higher floor, if the wire rope pulling the car breaks , then the elevator will plummet, causing serious safety accidents. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an anti-fall elevator and its control method, which aims to solve the problem that the elevator in the prior art has no anti-fall protection device and has potential safety hazards. The present invention has a simple structure and is easy to install. ...
