Description

{Seismic equipment for mechanical structures}

The present invention relates to a seismic apparatus for a mechanical structure, which can be fixedly supported on a lower portion of a mechanical structure, and has a buffer function by itself only by a bracket type by an earthquake or an external impact, And to an earthquake-proof apparatus for a mechanical structure which is easy to install.

In general, the types of mechanical structures in which the earthquake-proof facility is important include a power plant, telecommunication equipment, high-priced precision machinery, and large-sized pump devices. Particularly, when the parts with weak impact are gathered and their weight is heavier, the probability of occurrence of an earthquake is increased and the damage becomes larger.

In addition to this, various mechanical parts used in automobiles are complicated, and when an earthquake occurs, a failure of a battery of an engine or a hybrid vehicle corresponding to a weight occurs, and it is necessary to apply the earthquake- .

Below is a description of prior art techniques for supporting a structure made of a heavy body.

[1] In Japanese Laid-Open Patent Application No. 2012-0004314 (a seismic resistant device of a solar power generation facility), a body having a space portion therein and having coupling means for connection to a connection target structure at an upper portion or a lower portion thereof, A cushioning member that resiliently attaches to the side surface of the solar cell module and a fastening member that is coupled with the one end side connection target body and compresses the cushioning member while passing through the body, And the coupling means is coupled with a structure connected to the opposite side of the coupling means so that the vibration energy in the lateral direction due to the earthquake is transmitted to the buffer member So as to be absorbed through the surface.

Although the prior art has a slight vibration damping effect due to the cushioning member provided inside the main body, the body coupled with the structure is formed in an empty state, and thus the ability to support the photovoltaic power generation equipment itself is poor So that the body can be deformed by the vertical load. Therefore, when the body is deformed due to a strong earthquake, the function of the cushioning member provided therein is lost.

(2) Patent No. 1625389 (a seismic isolation device for a urethane shock absorber and a seismic spring-coupled type transmission / transmission system) includes an earthquake-resistant spring formed so as to surround a support portion inside upper and lower cases, and a plurality of earthquakes are formed in the longitudinal direction And a urethane shock absorber having a buffer function.

However, the above-mentioned prior art is merely a construction reinforced by inserting a urethane cushion into a spring, and a buffering function can be secured to some extent through a spring and a urethane cushion. However, a portion supporting the main body of the power & There is a structural problem that the body can not be smoothly supported because it is all of the part and the case and the supporting part can be easily deformed by the load.

(3) Patent No. 1539582 (seismic distribution board using an earthquake-proof damper) is composed of a pair of first and second bodies, wherein a first body is formed with a round groove at a central portion, and the second body is formed with round Wherein a round protrusion opposed to the groove is protruded on both sides of the first body and the second body, and joint portions of smooth surfaces are formed on both ends of the first body and the second body, And a high-damping rubber is disposed between the first body and the second body at both ends of the friction pad.

In the prior art, the buffer structure is composed of a friction pad and a high-damping rubber provided between the first body and the second body, and it is difficult to obtain a proper damping effect only by a high-damping rubber of a certain thickness, and the first body and the second body friction There is a problem that a large impact is transmitted as it is due to the structure in which the pad is brought into contact with the large surface with the space therebetween.

As described above, the conventional seismic resistant techniques include a buffer structure similar to that of a spring. Although these techniques have excellent buffering effect on the spring itself, the installation structure is complicated and a proper buffering effect can be obtained only in a specific direction. There is a structural problem that is vulnerable to the supporting ability and the load of the bearing. When the shock absorber is supported by a cushioning material such as a rubber pad without using a spring, it is effective for a small vibration, but has a problem that a buffering effect is remarkably deteriorated when a large shock is generated.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a cushioning device capable of obtaining a cushioning effect only by a bracket shape itself without including a cushioning structure such as a spring, It is an object of the present invention to provide a seismic isolation structure for a mechanical structure which has a rigid support structure to minimize deformation due to a load or an impact,
