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, which includes an anti-falling component and a control device. The control device includes an actuator assembly installed on the elevator car, a centrifugal jaw clutch installed on the actuator assembly, and a centrifugal jaw clutch. The passive teeth of the embedded clutch are connected with the executive connecting rod assembly, and the executive connecting rod assembly is connected with the anti-drop component; the executive mechanism assembly is provided with a wire rope, and the two ends of the wire rope are respectively connected to the top and the bottom of the elevator shaft. The anti-falling device of the elevator with the above structure adopts the method of mechanical detection and control device, and uses the speed of the centrifugal jaw clutch installed on the car to test the descending speed of the elevator, and realizes the braking of the anti-falling device. The detection speed of the anti-falling device is accurate, Few detection faults can significantly improve the working performance of the anti-falling device and improve the safety of elevator operation.

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....
