Embodiment approach 1

[0028] figure 1 It is a plan view of the main rope vibration damping device for an elevator according to Embodiment 1 of the present invention. figure 2 It is a side view of the main rope anti-vibration device for elevators, image 3 It is a diagram explaining the hammer used in the main rope vibration damping device for elevators.

[0029] Such as figure 1 and figure 2 As shown, one end of the three main ropes 4 is fixed to the car 2 installed in the hoistway 1 so as to be able to move up and down. The other end of the main rope 4 is fixed to the counterweight 3 .

[0030] Four anti-vibration ropes 10 are arranged around the main rope 4 . One end of each anti-vibration rope 10 is fixed to the rope fixing member 11 provided on the top 7 of the hoistway 1 , and the other end is fixed to the anti-vibration hammer 13 provided on the bottom 9 of the hoistway 1 . The anti-vibration hammer 13 applies downward tension to the anti-vibration rope 10 . The anti-vibration rope 1...

Embodiment approach 2

[0046] Next, use Figure 6 , the main rope vibration damping device for an elevator according to Embodiment 2 will be described. In Embodiment 2, the number of vibration-damping cables is reduced.

[0047] Figure 6 It is a plan view of the main rope vibration damping device for an elevator according to Embodiment 2.

[0048] Such as Figure 6As shown, in the main rope vibration damping device for an elevator, two vibration damping ropes 10 are provided, and are arranged in a diagonal direction when viewed from above the car 2 . In addition, the two anti-vibration ropes 10 intersect on the left side of the main rope 4 to form a V shape when viewed from above the car 2 . The anti-vibration part 21 is formed between the ceiling 7 of the hoistway 1 and the upper part 8 of the car 2 by two anti-vibration ropes 10 .

[0049] In this manner, in the main rope vibration damping device for an elevator according to Embodiment 2, the oscillation of the main rope 4 can be easily supp...

Embodiment approach 3

[0051] 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, a vibration damper is provided.

[0052] Figure 7 It is a plan view of the main rope vibration damping device for an elevator in Embodiment 3, Figure 8 It is a side view of the main rope anti-vibration device for elevators, Figure 9 It is a figure explaining the mathematical formula for calculating the position of the main rope vibration damper.

[0053] Such as Figure 7 and Figure 8 As shown, a vibration damper 16 is provided above the car 2 . Viewed from above the car 2 , the vibration damper 16 is shaped to surround the main rope 4 . The main rope 4 passes through the anti-vibration member 16 .

[0054] In addition, the vibration damper 16 is provided with vibration damper pulleys 17 on both left and right sides. At the vibration damper pulley 17 , the vibration damper rope 10 passes in the vertical directi...

Abstract

The main rope vibration damping device for an elevator of the present invention is used in an elevator having a main rope, one end of the main rope is fixed to a lifter installed in a hoistway freely and the other end is fixed to a counterweight. The main rope vibration isolating device for an elevator of the present invention has: a vibration isolating part, which is equipped with a vibration isolating member; The parts are arranged around the main rope, and one end is fixed on the top of the hoistway, and the other end is fixed on the tension imparting part. The anti-vibration part is in contact with the lifting body between one end and the other end. Between the top and the upper part of the lifting body.

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 with such a structure, if the hoistway sways 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, which hinders the operation of the elevator. [0003] Patent Documents 1 and 2 describe a vibration damping device that surrounds a main rope in an intermediate portion of a hoistway. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2014-227291 [0007] Patent Document 2: Japanese Patent Application Laid-Open No. 7-179279 Contents of the invention [0008] The probl...
