Embodiment approach 1

[0030] figure 1 It is a front view of an elevator equipped with the main rope vibration damping device for an elevator according to Embodiment 1 of the present invention.

[0031] like figure 1 As shown, one end of the three main ropes 4 is fixed to the car 2 which is installed in the hoistway 1 in a freely ascending and descending manner. The other end of the main rope 4 is fixed to the counterweight 3 . The car 2 constitutes a lifting body.

[0032] Around the main rope 4, a vibration damping rope 10 as a main rope vibration damping rope is provided. One end of the anti-vibration rope 10 is fixed to a rope fixing tool 11 provided on the ceiling 1 a of the hoistway 1 .

[0033] figure 2 Yes figure 1 A top view of the elevator shown. like figure 2 As shown, a disc-shaped rotating body 21 is provided on the upper portion 2 a of the car 2 so as to surround the main rope 4 . A motor (not shown) as a rotating body drive unit is attached to the rotating body 21 . The ro...

Embodiment approach 2

[0046] Next, use Figure 5 and Image 6 , the main rope vibration damping device for an elevator according to Embodiment 2 will be described. In Embodiment 2, the vibration-damping rope winds the auxiliary rope together with the main rope.

[0047] Figure 5 It is a front view of an elevator equipped with a main rope vibration damping device for an elevator according to Embodiment 2. like Figure 5 As shown, a rotating body 23 is provided on the upper part 2a of the car 2 . The rotating body 23 is rotated by an unillustrated motor as a rotating body drive unit. The drum 22 is provided on the rotating body 23 . The other end of the anti-vibration rope 10 is fixed to the drum 22 .

[0048] In the hoistway 1 , an auxiliary rope 30 is provided separately from the main rope 4 . One end of the auxiliary rope 30 is fixed to a rope fixing member 31 provided on the ceiling 1 a of the hoistway 1 . In addition, the other end of the auxiliary rope 30 is fixed to a rope fixing mem...

Embodiment approach 3

[0055] Next, use Figure 7 to Figure 9 , a main rope vibration damping device for an elevator according to Embodiment 3 will be described. In Embodiment 3, instead of the reel used in Embodiments 1 and 2, pulleys are used.

[0056] Figure 7 It is a front view of an elevator equipped with a main rope vibration damping device for an elevator according to Embodiment 3. One end of the anti-vibration rope 10 is fixed to a rope fixing member 11 on the ceiling 1 a of the hoistway 1 . The anti-vibration rope 10 descends obliquely downward in the hoistway 1 while making one turn around the main rope 4 . A rotating body 24 is provided on the upper portion 2 a of the car 2 . A motor (not shown) as a rotating body drive unit is attached to the rotating body 24 . The rotating body 24 is controlled to rotate clockwise and counterclockwise by the rotation of the motor. On the outer peripheral side of the rotating body 24, a direction changing portion 24a that is a pulley provided in t...

Abstract

A device for preventing shaking of a main rope for an elevator is used in an elevator having a main rope of which one end is secured to a raising / lowering body that is provided in a raising / lowering passage so as to be capable of being raised and lowered and of which the other end is secured to a balance weight, the device comprising a main rope shaking prevention rope and a twining tool for twining the main rope shaking prevention rope around the main rope. One end of the main rope shaking prevention rope is secured to the top part of the raising / lowering body. The twining tool twines the main rope shaking prevention rope around the main rope from one end to the other end of the main rope shaking prevention rope.

Description

technical field [0001] The present invention relates to a main rope anti-vibration device for an elevator that suppresses oscillation of the main rope of an elevator. Background technique [0002] The car of the elevator is guided by the guide rails fixed in the hoistway, and uses the main rope to go up and down in the hoistway. In an elevator having such a structure, if the hoistway shakes due to an earthquake or wind pressure, the main ropes resonate and vibrate greatly, and the car may come into contact with various equipment in the hoistway. In this case, the operation of the elevator is hindered. [0003] Patent Document 1 describes a main rope vibration damping device in which a plurality of vibration dampers through which a main rope passes through the center are sequentially placed on a support in a hoistway as the car descends. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2007-284222 Contents...
