Description

Technical Field [0001] The present invention relates to an eccentric-

The present invention relates to an anti-vibration device, and more particularly, to a vertical vibration control device, a rotation-preventing device, and a vibration damping device installed to attenuate mechanical vibration or seismic force, The present invention relates to an anti-vibration device using a spring capable of controlling vibration of a mechanical device caused by eccentricity and having an anti-seismic performance.

Korea is a small earthquake area and does not classify earthquake-resistant classifications for building electrical equipment. In general, all earthquake-resistant classes of building electrical equipments are set to "B".

However, architects and designers judge and decide from the standpoint of designing the importance of buildings.

In addition, the building electrical installations installed in buildings over 70m must calculate the floor seismic force of the building by applying dynamic analysis and determine the design seismic force acting on the center of the equipment considering dynamic amplification of the facility.

However, according to the seismic design standards of firefighting facilities, firefighting facilities installed in buildings with a height of 13m or more should be installed in accordance with the seismic design standards specified by the Minister of National Defense to ensure that firefighting facilities operate normally in the event of earthquakes .

Among machinery and building electrical equipments, earthquake resistance measures are required for main equipment and piping, including power transformers, self-power generators, battery equipments, main and power equipments, , The target building is a building of 70m or less. However, as described above, in the case of a firefighting facility, the target building is 13 meters or more in height.

Rotating equipment often installs anti-vibration devices. On the other hand, the transformer and the breaker also have a vibration damping device in order to prevent acoustic vibration or vibration due to magnetization or mechanical noise or vibration when it is closed.

Although the anti-vibration damping device uses a lot of spring anti-vibration devices, rolling, pitching and yawing rotations due to the eccentric load of the anti-vibration damping device are generated when the anti- Many occur.

As shown in FIG. 2, when the earthquake occurs, the spring vibration preventing device may be damaged due to the lack of the earthquake resistance due to the activity or the conduction moment, so that the earthquake damage of the main device mounted on the spring vibration preventing device may be caused.

It is necessary to prevent the vertical vibration control device, the anti-rotation device, and the vibration damping device from being broken due to the excessive external force by preventing the mechanical device from being caused by the earthquake due to the lack of the seismic performance. .

The seismic force is judged to act on the center position of the device, and the type of fall prevention device is selected by examining the possibility that the device will conduct.

The member of the anti-fall device is selected to be able to withstand the seismic force acting according to the type of anti-fall device.

An anti-fall device is fixed to a foundation or a structure with a bolt or the like so as not to generate an action when the seismic force acts.

When selecting an anti-fall device, select the anti-fall type when using a vibration device with a large vibration amount, such as a spring.

Equipment that installs anti-vibration devices may cause excessive vibration due to seismic motion, so anti-fall devices should be installed to prevent activity and conduction.

 There are various kinds of dustproof materials and dustproof devices, and there are various associations with devices. In addition, the type of the anti-fall device is various, and examples of the fall prevention device that is mainly used are as follows.

1. Anti-motion type - It is made of steel plate or steel plate, mainly used to prevent horizontal movement. Fig. 1-1 shows an L-plate type anti-fall device which is an anti-motion type.

2. Activity and anti-fall type - It is made of steel or steel plate and used to prevent horizontal movement and conduction. Fig. 1-2 shows a crank plate type anti-fall device which is an active and anti-fall type.

3. Others - Examples of other anti-fall devices are shown in Figures 1-3.

In case of foreign earthquake damage, the equipment supported by anti-vibration device has suffered damage or ineffective operation when the anti-fall prevention device is not installed or the installation method is incomplete. The car conductor or anti-vibration bracket is damaged.

In order to protect the equipment mounted on the vibration isolating device from earthquake vibration, it is necessary to use a non-contact type external device such as a spring anti-vibration device or a vibration isolating pad installed in a transformer, Respectively.

Such an anti-fall device should be installed with a large-scale anti-fall device to prevent activity and conduction when the device is under high load or the center of gravity of the device and the height of the device are very high. It is difficult to install.

In addition, there is a great possibility that the apparatus is damaged by an impact caused by earthquake vibration depending on the installation interval in a non-contact manner.

For devices equipped with anti-vibration devices, anti-fall devices should be installed considering the weight and displacement of the device, and anti-fall devices should be installed with sufficient strength for heavy equipment with large displacement of transformers and switchboards.

At this time, it is preferable to set the gap of the conduction preventing device to about 2 mm, and to set the maximum dimension so that the vibration of the transformer is not transmitted to the bottom.

Generally, when a large vibration such as an earthquake occurs, the support pipe is fixed to the clearance between the two support pipes so that the spring can no longer exhibit the vibration-proof performance.
