Problems solved by technology

However, when the elevator is running, the phenomenon of the elevator falling occasionally occurs, which seriously threatens the safety of people's lives and property, resulting in irreparable losses.
[0003] Some elevator anti-falling devices are disclosed in the prior art, including anti-falling components and control devices, but most of the control devices use photoelectric control devices. Although this kind of device has a high degree of detection, it also has a state of detection failure, which leads to the elevator falling. danger

Abstract

The invention discloses an elevator anti-falling device. The elevator anti-falling device comprises an anti-falling part and a control device. The control device comprises an actuator assembly installed on an elevator car and a centrifugal jaw clutch installed on the actuator assembly, a driven gear of the centrifugal jaw clutch is connected with an execution connecting rod assembly, and the execution connecting rod assembly is connected with the anti-falling part. A steel wire rope is wound on the actuator assembly, and the two ends of the steel wire rope are connected with the top and the bottom of an elevator shaft. The mode of mechanical detection control devices is adopted in the elevator anti-falling device of the structure, the falling speed of an elevator is detected by using the rotation speed of the centrifugal jaw clutch installed on the car, braking of the anti-falling device is realized, the anti-falling device is accurate in detection speed and has a few detection faults, the working performance of the anti-falling device can be obviously improved and the safety of operation of the elevator is improved.

Description

technical field [0001] The invention relates to an anti-falling device, in particular to an elevator anti-falling device. Background technique [0002] With the continuous development of urban construction and the continuous increase of high-rise buildings, elevators are widely used in the national economy and life. As a means of transportation running vertically in high-rise buildings, elevators are inseparable from people's daily life. However, when the elevator is in operation, the phenomenon of elevator falling occurs occasionally, which seriously threatens the safety of people's lives and property, and causes irreparable losses. [0003] Some elevator anti-falling devices are disclosed in the prior art, including anti-falling components and control devices, but most of the control devices use photoelectric control devices. Although this kind of device has a high degree of detection, it also has a state of detection failure, which leads to the elevator falling. danger....
