Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seismic isolation device, and more particularly, to a seismic isolation device that is installed at a lower portion of a protected object to reduce vibration and impact applied from the outside to safely protect the protected object.
Generally, when an earthquake occurs, even if the building itself is fine, it is often the case that the objects in the room fall down or the inner appliance or the equipment collides with each other due to vibration of the building (vibration) .
Therefore, apart from the seismic design of the building itself, there is a need for an isolation device that absorbs vibration generated by an earthquake or the like and protects equipments and objects installed on the supporting surface.
The conventional LM guiding device includes a lower panel, a first LM guide installed on the upper surface of the lower panel, a second LM guide installed on the upper portion of the first LM guide, An upper panel installed on an upper portion of the guide and a buffer spring installed on the first or second LMP guide to damp the transmission of vibration by equipment or objects stacked on the upper panel.
As shown in FIG. 1, the conventional first and second ELM guides include a rail member (not shown) provided at the lower portion of the upper panel and the upper panel of the lower panel, (15) which are stacked on the rail member (11) while reciprocally moving along the guide bar (13) while maintaining a predetermined gap with the rail member (11) And a

As described above, the conventional LM guide consumes a longer time to manufacture the
SUMMARY OF THE INVENTION The present invention has been conceived in order to solve the above-mentioned problems, and it is an object of the present invention to provide a rolling device, which is provided with an inclined roller between a rail member constituting a lower guide and an upper guide and a block member rolling in a longitudinal direction of the rail member, The present invention is to provide an isolation device in which the outer shape of the roller is not required to be deformed because it is possible to tightly contact the block member so as to be rotatable,
In order to achieve the above object, the present invention provides a base isolation device comprising a lower plate, a lower guide provided on the lower plate, an upper guide installed perpendicularly to the lower guide and rolling in a direction perpendicular to the lower guide, Wherein the lower guide and the upper guide include a rail member having roller guide members on both sides thereof, and a block having a plurality of inclined rollers that are tilted in contact with the roller guide member, .
The rail member includes a first inclined portion inclined to the inward lower portion, a second inclined portion inclined to the lower side in the outward direction from both ends of the first inclined portion, and a guide seat portion provided in the outward direction from both ends of the second inclined portion The block member may include a fourth extension portion extending inwardly and a third slope portion inclined upward inwardly from both ends of the fourth extension portion.
The inclined roller may be installed on the third inclined portion such that the rotation center axis thereof is perpendicular to the third inclined portion and the second inclined portion.
The inclined roller may contact the first inclined portion when the contact with the roller guide member drops.
An auxiliary roller may be installed on the block member between the inclined roller and the inclined roller.
The auxiliary roller may be installed such that the rotation center axis is horizontal.
The buffer member is provided on the lower plate in a direction orthogonal to the lower guide. The buffer member includes a spring supporter spaced apart from the lower guide in a direction perpendicular to the lower guide, and a buffer spring installed between the spring supporter and the block member. .
According to the seismic isolation device of the present invention as described above, the inclined roller is installed between the rail member constituting the lower guide and the upper guide and the block member rolling in the longitudinal direction of the rail member, So that it is not necessary to apply a preload to the rollers separately, and the flat outer circumferential surface of the rollers can be closely contacted and rotated, so that there is an effect that the outer shape of the roller is not required to be deformed.
