[0001]

The present invention relates to a highway, a national highway,
The present invention relates to a pole with a vibration damping device used for a lighting pole, a lamp section, a transmission tower, an advertising tower, etc. used in a long bridge. That is, the present invention relates to a pole having a high-viscosity liquid such as silicone oil and a vibration damping device which is immersed in the high-viscosity liquid and is supported by interposing a metal spring. The present invention relates to a pole with a vibration damping device, which is advantageous in achieving vibration damping.

2. Description of the Related Art Conventionally, there is known a vibration damping device to be installed on a lighting pole and a power transmission tower installed on a highway, a national highway or a long bridge, and also on an advertising tower where vibration is a problem. The following have been proposed as conventionally known damping devices. The conventional techniques are roughly classified into "chain type" and "steel ball type". When the steel pipe pole vibrates due to wind, etc., the chains and steel balls installed on the steel pipe pole vibrate, these collide with the steel pipe pole, and the vibration energy of the pole is reduced. The buffer inner wall or steel pipe pole may be damaged. For example, as disclosed in Japanese Unexamined Patent Publication No. 61-29003, a vibration damping device that suspends a chain in a vertical pole for an illumination lamp and expects a vibration damping effect due to a collision between the chain and an inner cylinder of the illumination lamp is also available. Are known. Also,
Japanese Patent Application Laid-Open No. 61-229004 discloses a vibration control device for horizontal members.
In the publication, a damping device is also known in which a chain extending laterally through the inside of a horizontal cylinder of an illuminating lamp is stretched, and a vibration damping effect is expected due to a collision between the chain and the inner cylinder of the illuminating lamp. There is. In these vibration damping devices, the vibration damping devices are distributed and installed on the upper part or the central part of the illumination column in accordance with the portion of the vibration mode where the displacement is large. Moreover, in order to secure 1% of the damping constant that is estimated not to generate the Karman vortex, the chain weight is about 1/2 of the lighting pole weight.
The inner wall of the steel pipe pole is provided with urethane lining in order to reduce the noise at the time of collision with the chain of 5 (about 30 kg). Further, as disclosed in Japanese Patent Application Laid-Open No. 3-86227, a spherical vibration damper is placed in a room that vertically divides the interior of the illuminating lamp, and vibration is suppressed by collision between the wall and the vibration damper. Further, as a vibration damping device for an illumination column, the one disclosed in JP-A-63-63804 is also known. In the case of this illumination column, it is expected that a viscous body is enclosed in the upper half space to reduce vibration by sloshing of the viscous body. Similar to the chain-type vibration control device, these vibration control devices are distributed in the upper part of the lighting pole or in the central part according to the large displacement of the vibration mode in order to obtain high vibration control effect. In order to reduce the noise at the time of steel ball collision, the weight of the steel ball should be 4-5% of the weight of the lighting pole as well as the chain type vibration damping device. , Urethane lining is installed on the inner wall of the steel pipe pole.

[0003]

In the case of the above conventional vibration damping device, the chain or the steel ball in the vibration damping device installed on the steel pipe pole vibrates almost simultaneously with the vibration of the steel pipe pole.
Repeated collisions with the inner wall of steel pipe poles. Therefore, the urethane lining provided on the inner wall of the steel pipe pole or the like is worn, and the inner wall of the steel pipe pole or the like directly collides with the chain or the steel ball, which causes a problem that noise at the time of collision becomes large. Further, due to the abrasion of the urethane lining, the inner wall of the steel pipe pole or the like directly collides with the chain or the steel ball, and the coefficient of restitution at the time of collision becomes small. Furthermore, in the case of the conventional vibration damping device, since the vibration damping effect of only one of horizontal vibration and vertical vibration is obtained,
When horizontal vibration and vertical vibration simultaneously act, there is a drawback that both a horizontal vibration damping device and a vertical vibration damping device must be installed. Furthermore,
In the conventional case, there is a drawback in that the vibration damping effect against relatively low frequency vibration is low.

[0004]

In order to advantageously solve the above problems, in the pole with the vibration damping device of the present invention,
The metal vibration damping frame 1 is fixed to the pole body 2, the spring supporting portion 3 is provided on the upper portion of the vibration damping frame 1, and the metal spring 4 is placed on the upper surface of the spring supporting portion 3, and The upper part of the support rod 6 mounted with the weight 5 arranged in the vibration frame 1 is supported by the supporting metal fitting 7 placed on the metal spring 4, and the weight 5 is filled in the damping frame 1. It is immersed in the highly viscous liquid 8 thus prepared. Further, in order to advantageously solve the above-mentioned problems, the vibration damping frame 1 made of metal is fixed to the outside of the pole body 2, and the spring bearing portion 3 is provided on the upper portion of the vibration damping frame 1. The metal spring 4 is placed on the upper surface of the support rod 3, and the upper part of the support rod 6 having the weight 5 arranged in the damping frame 1 is supported by the support metal fitting 7 placed on the metal spring 4. However, it can be advantageously solved by immersing the weight 5 in the high-viscosity liquid 8 filled in the damping frame 1. Furthermore, the weight 5
The above-mentioned problem can be advantageously solved by adding a structure in which the upper portion of the support rod 6 to which is attached is supported by the support metal fitting 7 so that the position can be adjusted.

[0005]

When the vibration is input to the vibration damping frame 1, the weight 5 suspended and supported via the metal spring 4 vibrates, and the vibration energy of the weight 5 is immersed in the weight 5. It is absorbed by the high-viscosity liquid 8 in the part where it is operating. As a result, the pole is controlled. Further, since the weight 5 is supported with the metal spring 4 interposed, the weight 5 can vibrate not only in the vertical direction but also in the horizontal direction. Therefore, the vibration energy in both directions can be absorbed by the highly viscous liquid 8. It also suppresses the pole against simultaneous vibrations in both vertical and horizontal directions. Further, since the weight 5 is supported with the metal spring 4 and the support rod 6 interposed, the weight 5 does not have a specific directionality with respect to the horizontal direction, so that vibration in an arbitrary horizontal direction or Since vibration occurs even if an arbitrary vibration of relatively low frequency in the horizontal direction is input, the vibration energy is absorbed by the highly viscous liquid 8 and the pole is damped.
