Vibration-proof device

Abstract

The invention provides a vibration-proof device which guarantees that vibrating equipment supported by the vibration-proof device cannot be damaged and have faults even if being applied with strong horizontal force during earthquake, and the vibrating equipment can also have the same vibration-proof effect after the earthquake as that before the earthquake. The vibration-proof device used for reducing the transmission of vibration direction supporting bodies of the vibrating equipment comprises a base plate (2), a cover plate (3), a vibration absorption component (5) and a connecting and guiding component (6), wherein the base plate (2) is arranged on the supporting bodies such as a foundation; the cover plate (3) is configured above the base plate (2) and used for mounting the vibrating equipment; the vibration absorption component (5) is inserted among the plates and can be elastically deformed up and down; the connecting and guiding component (6) is used for connecting the base plate (2) and the cover plate (3) in a mode of not separating the base plate (2) and the cover plate (3) by more than a preset distance and guiding the cover plate (3) supported by the vibration absorption component (5) to have a displacement along the vertical direction; and a vibration resistant mechanism (7) is arranged in the connecting and guiding component (6) and used for limiting the relative horizontal displacement of the base plate (2) and the cover plate (3) within a certain distance.

Description

technical field [0001] The present invention relates to an anti-vibration device interposed between vibration equipment such as cooling towers, refrigerators, generators, outdoor units of air conditioners, piping / pipes, etc. that generate vibration, and supports such as ground, foundation, and base Space and absorb vibration, reduce the vibration transmitted from the vibration equipment to the support body, and prevent the glass and other surface materials installed on the surrounding buildings from resonating due to vibration, resulting in noise like ringing. Background technique [0002] As such an anti-vibration device, for example, a kind of anti-vibration device 1 is disclosed in Patent Document 1, which has: a member 2 for fixing the ground made of a rectangular metal plate; Rectangular metal cup-shaped vibration source installation part 3; Interposed between the foundation fixing part 2 and the vibration source installation part 3 isolator 4 made of coil springs; and ...

AI Technical Summary

Problems solved by technology

Therefore, the steel material (bolt) of the guide bar 7 breaks, or even if it does not break, it yields and is permanently twisted and accumulated. After the earthquake, the vibration-proof device cannot exert the same vibration-proof effect as it did at the beginning.
