Anti-falling elevator

Abstract

The invention relates to an anti-falling elevator. The anti-falling elevator comprises an elevator shaft and an elevator lift car. The elevator lift car is arranged in the elevator shaft in a manner that the elevator lift car can move vertically. The anti-falling elevator is characterized in that the anti-falling elevator comprises multiple friction locating mechanisms, multiple flexible limitingmechanisms, two friction guide rails, a standby power module, a speed monitoring module, a master control circuit module and an automatic power switch; the two friction guide rails are arranged on theleft inner wall and the right inner wall of the elevator shaft correspondingly. The friction locating mechanisms and the flexible limiting mechanisms are arranged on the left side wall and the rightside wall of the elevator lift car correspondingly and act on the corresponding friction guide rails. The standby power module, the speed monitoring module, the master control circuit module and the automatic power switch are arranged at the top of the elevator lift car. The anti-falling elevator has the advantages of being simple in structure, high in automation degree, steady in operation, goodin reliability, high in safety performance, long in service life, easy to popularize and promote and the like.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an anti-fall elevator. Background technique [0002] With the popularization and application of elevators, safety accidents related to elevators have occurred more and more frequently, seriously threatening the safety of the passengers. At present, most elevator cars are pulled by steel ropes to drive the car to move up and down. The weight of the entire car and the weight of the passengers will be applied to the steel ropes. Therefore, the quality of the steel ropes is seriously related to safety of passengers. Especially for some older elevators, due to the perennial operation, the steel rope is prone to aging and deformation, and even over-age operation. Moreover, the running and wear conditions of the steel ropes are not easy to be directly checked. During the inspection process, the corresponding damaged steel ropes are prone to missed inspections and wrong inspections. ...

Especially for some old elevators, due to the perennial operation, the steel rope is prone to aging and deformation, and even over-age operation

Moreover, the operation and wear of the steel ropes are not easy to be directly checked. During the inspection process, the corresponding damaged steel ropes are prone to missed inspections and wrong inspections.

These problematic steel ropes are prone to breakage during operation. Once the steel rope breaks, it will cause serious safety accidents and even cause serious casualties.
