Air slider in air suspension type vibration control device

Abstract

The purpose of the present invention is to provide a new improvement in an air slider in an air-suspended vibration control device. This air slider (11) is provided with: an attachment surface (12) to be attached to a vibration control stand (3); a slider body (14) which is disposed at the lower part of the mounting surface (12), and which has a cylindrical protrusion (14A) on the lower surface peripheral wall section, the cylindrical protrusion (14A) defining an air chamber (13) between the cylindrical protrusion (14A) and the upper surface of the vibrating base (2), and the end surface of the cylindrical protrusion (14A) seating on the upper surface of the vibrating base (2) when air supply is blocked; an air flow path (22) for supplying air from an air source to the air chamber (13); and a sealing material (15) for preventing air leakage, the sealing material (15) being disposed so as to surround the air chamber (13) across the space between the slider body (14) and the vibration base (2).

Description

technical field [0001] The present invention relates to an air slider in an air-suspension type vibration control device, and specifically relates to a brand-new air slider in an air-suspension type vibration control device that improves the sliding function during vibration control operation. Background technique [0002] The use of seismic isolation devices to protect buildings or important machines (equipment) from damage caused by earthquakes has become popular. The components of the isolator are mainly laminated rubber, sliding bearings, and rolling bearings. However, if the isolator is applied with air suspension, a high-performance isolator with reduced friction can be realized. However, the applicable range is actually limited. [0003] Patent Document 1 discloses a shock isolation device, wherein the air ejection mechanism is arranged on the lower surface of the shock isolation table, and the receiving surface for air ejection is set as the upper surface of the air...

AI Technical Summary

Problems solved by technology

[0004] However, the seismic isolation device of Patent Document 1 has problems in that there is no sealing material for preventing air leakage, and there are problems such as insufficient air leakage prevention measures for the air ejection to the upper surface of the air supply device housing box.

[0005] As mentioned above, in the field of vibration control devices that control the vibration of the object by air suspension (vibration isolation, etc.), the current situation is that no high-performance air slider has been seen until now.
