High-floor escape elevator of pure mechanical structure

Abstract

The invention discloses a high-floor escape elevator of a pure mechanical structure. The high-floor escape elevator comprises an elevator shaft shell, an elevator car and a lifter; the elevator shaft shell is provided with an elevator shaft shell body, a counterweight shaft and a pulley cavity, wherein the counterweight shaft is located on the left side of the elevator shaft shell; the pulley cavity is located on the upper side of the counterweight shaft; the elevator car is slidably connected inside the elevator shaft shell; the left end of the elevator car is fixedly connected with the lifter; the lifter is provided with a rope winding cavity; a rope winding shaft is rotationally connected between the front cavity wall and the rear cavity wall of the rope winding cavity; the pure mechanical structure ensures that the elevator can be used even under a power failure condition and has the advantages of rapid response and less faults. The structure of the elevator is relatively closed, is not prone to causing a dense smoke effect, and has a large loading capacity; when the elevator is used by a plurality of people, the weight of the elevator car is balanced through a balance weight so as to reduce the load during descending; and moreover, the balance weight can be manually unloaded when the elevator is used by few people and the weight of people is not higher than the balance weight.

Description

technical field [0001] The invention relates to the related field of elevator equipment, in particular to a high-floor escape elevator with a purely mechanical structure. Background technique [0002] Nowadays, high-rise buildings can be seen everywhere, but escaping in high-rise buildings is not an easy task. It is well known that in the event of disasters such as fires and earthquakes, conventional elevators cannot be used, and the evacuation of people in high-rise buildings has become a major problem; [0003] In the event of a fire, the power outage that may cause the elevator to stop working is a major reason why the elevator cannot be used when escaping. Nowadays, there are fire-resistant, smoke-proof, high-temperature-resistant fire-fighting elevators, but there are still problems of jamming during power outages.
