Embodiment approach

[0039] The spliced ​​air bearing vibration isolation platform consists of a T-shaped platform body 1, a granite flat plate splicing unit 2, and an air spring 3. The cross-sectional dimensions of the T-shaped table body 1 are as follows: image 3 As shown, the length is 7m, the width is 3.6m, the height is 2.3m, and the height of the flange is 0.6m; the material of the T-shaped table body 1 is C40 concrete and HRB400 steel bar, and the specific reinforcement is detailed in image 3 . The vibration isolation platform table is composed of 10 granite slab splicing units 2. The vibration isolation platform table has a length of 1800mm, a width of 1400mm, and a thickness of 150mm. Figure 4 As shown: the distance between the glue injection holes is ≤300mm, there are 5 φ25 leveling holes on the board, 4 of which are also used as hoisting holes 7, and the glue injection holes are also used as mounting holes for inserts. The hole sealing area is inside the dotted line. The injection ...

Abstract

The invention provides a spliced ​​air bearing vibration isolation platform and an installation method, belonging to the technical field of air spring vibration isolation. It solves the problems of limited processing size, high center of mass, heavy weight, high cost and limited transportation of traditional granite air flotation platforms. It includes a T-shaped table body, a vibration-isolation platform table and an air spring. The vibration-isolation platform table includes a plurality of granite slab splicing units, and the multiple granite slab splicing units are fixedly spliced ​​and installed on the T-shaped table body. The granite The slab splicing unit and the T-shaped platform are connected by structural glue, and the structural glue forms a structural pier array between the granite slab splicing unit and the T-shaped platform. The number of the air springs is multiple. The length direction of the T-shaped platform body is supported under the flanges on both sides of the T-shaped platform body. It is mainly used for air bearing vibration isolation platform.

Description

technical field [0001] The invention belongs to the technical field of air spring vibration isolation, and in particular relates to a spliced ​​air bearing vibration isolation platform and an installation method. Background technique [0002] In the production of the previous air-floating vibration isolation platform platform, the platform material is mainly made of concrete, steel optical flat plate, and integral granite flat plate material. Among the above three materials, the surface flatness of granite slabs achieves the highest processing accuracy. The flatness of concrete materials is generally 1-3mm, and the flatness of granite materials with a length of less than 4m is generally below 23μm, and granite slabs also have a linear expansion coefficient. The advantages of small size, no additional processing stress, wear resistance, and corrosion resistance make it the best choice for air bearing platform structures required for high-precision machining, high-precision op...
