The invention discloses a safety elevator capable of preventing sudden accidents and facilitating rapid escape of passengers. The safety elevator comprises an elevator shaft; an elevator base is glidingly arranged in the elevator shaft; an elevator lifting sliding groove with an upward opening is formed in the end surface of the top of the elevator base; six sets of threaded block sliding grooves with upward openings are formed in the inner top wall of the elevator base and located on the left side and the right side of the elevator lifting sliding groove in a bilateral symmetry mode; emergency lifting mechanisms used for lifting the elevator under the emergency condition are arranged in the threaded block sliding grooves. In the technical scheme, according to the safety elevator capable of preventing the sudden accidents and facilitating rapid escape of the passengers, a centrifugal structure is used for detecting whether the elevator is abnormal to cause falling or not, emergency braking of the elevator is automatically completed when the elevator is abnormal, the safety of personnel in the elevator is protected, the safety of the elevator is greatly improved, and meanwhile, after emergency braking, the elevator is automatically connected with a normal elevator door, so that people can escape conveniently, and the escape difficulty and the escape danger caused by abnormally opening the elevator door are avoided.
本发明公开了一种预防突发意外便于乘客快速逃生的安全电梯,包括电梯井;所述电梯井内滑动设有电梯基座,所述电梯基座顶部端面上设有开口向上的电梯抬升滑槽,所述电梯基座内顶壁上设有位于所述电梯抬升滑槽左右两侧左右对称的六组开口向上的螺纹块滑槽,所述螺纹块滑槽内设有用于紧急情况下抬升电梯的紧急抬升机构;本技术方案中的一种预防突发意外便于乘客快速逃生的安全电梯,利用离心的结构检测电梯是否出现异常导致坠落,并在异常时自动完成对电梯的紧急制动,保护电梯内人员的安全,极大的提高了电梯的安全性,同时在紧急制动后,自动使得电梯与正常的电梯门接轨,便于人员的逃生,避免了非正常打开电梯门造成逃生困难以及逃生时的危险。
