Abstract

The invention relates to a package-type rubber vibration isolation cushion with limit function, comprising a limit rod, miniature rubber vibration isolation units, laminated steel plates and end plates; wherein a plurality of miniature rubber vibration isolation units are fixed between each two laminated steel plates, the limit rod is a soft steel rod with the section gradually changed, the end with larger section is fixed on a lower end plate, and the limit rod penetrates the limit holes on the intermediate laminated steel plates from bottom to top. The invention has the advantages of variable structure size, adjustable energy consumption capability, wide application range, simple manufacturing process, convenient transportation and flexible application, is applicable to standardization mass production of factory and field selecting and mounting by requirement and can be applicable to vibration resistance of structure and equipment, especially vibration resistance, vibration reduction and vibration isolation of special industrial equipment with small load and frequent field debugging.

Description

technical field [0001] The invention relates to a position-limiting assembled rubber shock-absorbing pad. Background technique [0002] Earthquakes cause serious damage to various building structures and equipment, and will lead to paralysis of the entire social life. Base isolation technology is the most widely used vibration control technology in engineering, and it is a new technology that appeared in the 1960s. Base isolation can be divided into interlayer rubber pad isolation devices, lead rubber bearings, ball (or roller) isolation, suspension base isolation, swing bearing isolation, sliding bearing isolation, etc., among which rubber Bearing isolation technology is the most widely used and most mature type of isolation technology. It has the characteristics of clear shock absorption mechanism, remarkable shock absorption effect, convenient construction and installation, and many projects have been used in actual earthquakes. Standing the test, it is being valued by ...
