High-load-bearing full-sealed disk-type structure vibration isolation device

Abstract

The invention provides a high-load-bearing full-sealed disk-type structure vibration isolation device. The vibration isolation device mainly comprises a cover plate, a disk-type structure vibration isolator and a bottom basin. The disk-type structure vibration isolator is arranged between the cover plate and the bottom basin in a surrounded mode. The disk-type structure vibration isolator is of acentral symmetry structure. The center of the disk-type structure vibration isolator protrudes upwards to form an elastic deformation part. The outer edge of the elastic deformation part extends outwards to form a supporting part. The center of the elastic deformation part serves as a supporting platform. The upper surface of the supporting platform makes contact with and is matched with the lowersurface of the cover plate. The lower surface of the supporting platform does not make contact with the upper surface of the bottom basin. The periphery of the supporting platform is connected with ataper tube section inclined downwards. The supporting platform is connected with the supporting part through the taper tube section. The taper tube section is provided with a plurality of holes. Thethickness of the taper tube section gradually decreases from the supporting platform to the supporting part. The high-load-bearing full-sealed disk-type structure vibration isolation device achieves the vibration isolation effect in a pure structure form and is placed on a supporting part of a vibration isolated body to reduce the vertical stiffness appropriately, and the vertical fundamental frequency keeps away from the main frequency of vibration of the upper structure. Accordingly, the vertical vibration isolation function is achieved.

Description

technical field [0001] The invention relates to the technical field of vibration isolation used in equipment, bridges or buildings, and specifically relates to a vibration isolation device with a high-load full-sealed disc structure. Background technique [0002] The vibration isolation device is an elastic element connecting the superstructure such as equipment, bridge or building and the foundation, to reduce and eliminate the vibration transmitted from the superstructure to the foundation and the vibration transmitted from the foundation to the superstructure. Currently commonly used vibration isolation devices include steel spring vibration isolators, metal rubber vibration isolators, rubber vibration isolators, air cushion vibration isolators, and vibration isolation pads. The above-mentioned vibration isolation devices have their own applicable working conditions, but all have the disadvantage of small bearing capacity.

Problems solved by technology

The above-mentioned vibration isolation devices have their own applicable working conditions, but they all have the disadvantage of small bearing capacity

When the self-weight of the upper structure is small, it can meet the bearing capacity requirements, but when the weight of the upper structure of the vibration isolation device reaches 100 tons or more, unless the number of vibration isolators is greatly increased, it is difficult to meet the bearing capacity requirements

However, if there are too many vibration isolators, the basic structure will inevitably become larger, which will not only increase the construction cost, but also increase the difficulty of designing the entire basic structure.
