Elevator accompanying cable protection device

Abstract

The invention discloses a protective device for an elevator accompanying cable, which comprises an anti-rope sheave assembly, which can move up and down along a vertical guide; Synchronous movement; the roller guide mechanism for accompanying cable protection is fixedly connected with the anti-rope pulley assembly, and the elevator accompanying cable passes through the roller guide mechanism for accompanying cable protection to prevent the elevator accompanying cable from swinging during the elevator movement. The present invention can fundamentally and effectively solve the problem of vibration and swing of the accompanying cable during elevator operation by adding a fixing device at the lower part of the accompanying cable and simultaneously provide tension for the accompanying cable, and avoid collisions between the accompanying cable and hoistway components during movement. Thereby avoiding the risk of the accompanying cable being broken during the operation of the elevator, while improving the service life of the accompanying cable and ensuring the smooth operation of the elevator.

Description

Technical field [0001] The invention relates to an elevator accessory, in particular to an elevator cable protection device. Background technique [0002] The elevator accompanying cable is a channel for transmitting information and instructions between the elevator car and the machine room control cabinet. One end of the elevator traveling cable is connected with the machine room control cabinet, and the other end is fixed on the elevator car and moves with the elevator car. As the height of modern buildings continues to increase, the length of the elevator cables also increases. [0003] As the elevator accompanying cable has no guiding and tensioning device, the elevator accompanying cable will sway when the elevator is running and stopped. What is more dangerous is that when the building encounters strong wind or earthquake, the elevator accompanying cable will vibrate with the building There is a large swing, and the higher the building height, the greater its amplitude.

AI Technical Summary

Problems solved by technology

However, this protective measure cannot fundamentally eliminate or reduce the swing of the accompanying cable; in addition, after the elevator has been used for a long time, the protective device may be damaged and cause damage to the elevator accompanying cable; the noise generated after the elevator accompanying cable collides with the protective device will also Affect the mood of passengers; and if the above-mentioned protective device is used for the sightseeing elevator, it will have an impact on the aesthetics of the elevator
