Vibration-stopping device of elevator cable

Abstract

The present invention provides a vibration-stopping device of an elevator cable, which can beforehand prevent the clamping of device, etc. used for maintenance checking operation between the handrail, etc. installed on a cage and the vibration-stopping device of cable. Furthermore the clamping of dragging cable, etc. by the vibration-stopping component does not generate. The vibration-stopping device is formed to comprise the following components: a first vibration-stopping component and a second vibration-stopping component which are provided with a vibration-stopping arm which is configuredbetween the cage and a lifting path of a counterweight, a vibration-stopping shaft part connected with one end of the vibration-stopping arm, and a rotating range restricting part which restricts therotation of the vibration-stopping arm from a horizontally inwards position to the vertical lower part; and a first shaft base and a second shaft base which are configured at positions with approximate same heights and support the vibration-stopping shaft part at the part adjacently to the back surface of the counterweight rail with a mode that the vibration-stopping shaft part can rotate freely.When the upward load is exerted to the vibration-stopping arm from the lower part, the vibration-stopping arm and the vibration-stopping shaft part rotate upwards integrally.

Description

technical field [0001] The invention relates to an elevator rope anti-vibration device. Background technique [0002] With regard to the existing elevator rope anti-vibration devices, there is known such a technology: due to the vibration of the building during an earthquake or strong wind, etc., the traction ropes and control cables connected to the car or counterweight arranged in the hoistway , or the ropes of the speed limiter, etc. swing greatly, thereby interfering with the equipment installed in the hoistway, in order to prevent the above situation, the car and the counterweight are suspended from the traction rope In the elevator device in which the lower surface is hung on the lower surface of the above-mentioned car through a compensating sheave, at least one rope anti-vibration device is arranged in the direction of the upward and downward movement path of the above-mentioned counterweight. The rope anti-vibration device includes: a mounting part, They are mounte...

AI Technical Summary

Problems solved by technology

[0006] However, in the conventional elevator rope anti-vibration device shown in Patent Document 1, since the rope anti-vibration device is fixedly installed between the car and the counterweight at a predetermined interval, it is difficult for maintenance workers to climb on the ceiling of the car. When performing maintenance and inspection work, when the car is moved, there is a problem that equipment for the maintenance and inspection work may be caught between the handrails and the like installed on the car and the rope vibration isolating device, thereby Impedes the movement of the car; or the maintenance worker may come into contact with the rope damping device

[0007] In addition, in the conventional elevator rope anti-vibration device shown in Patent Document 2, there is a problem that the hoisting ropes connected to the car or the counterweight arranged in the hoistway are damaged by earthquakes or strong winds. When the building swings and vibrates greatly, the traction rope, etc. may be caught by the receiving part that locks the other end of the vibration damping member, or caught between the receiving part and the vibration damping member.

[0008] In addition, due to the heavy weight of the anti-vibration member, the load required to rotate it upward becomes large, so there is also a problem that the handrails and the like installed on the car are caught between the handrails, etc. In the case of vibration dampers, the shock becomes larger

In this case, Patent Document 2 describes a technique of using weights or springs to balance the weight so that the vibration damping member can rotate easily. However, there is a problem that the structure of the vibration damping device becomes complicated in this way.
