[0061] By arranging a plurality of vibration isolation springs 400 in an array and vulcanizing the vibration isolation rubber to form an integral elastic deformation assembly, the elastic deformation performance is superior, has higher load capacity and large deformation beam, and has better vibration and noise reduction effect; preferably, one or more of disc springs, coil springs, plate springs and coil springs are used.

[0062] Assembly method and working principle

[0063] The multi-dimensional vibration isolation support described in the embodiment is used to fix the bottom of the constraint box on the equipment lower structure 800 through the second anchor, so that the constraint box is rigidly fixed with the equipment lower structure;

[0064] Then, the elastic deformation assembly filled in the cavity of the constraint box is filled;

[0065] Then, the conversion base is arranged in the constraint box, that is, the lower cover plate 220 of the conversion base 200 is arranged in the cavity of the constraint box and abuts against the elastic deformation assembly in the cavity of the constraint box; the periphery of the lower cover plate 220 of the conversion base is tightly matched with the inner wall of the vertical plate of the constraint box, and the horizontal limiting of the lower cover plate is formed by the inner wall of the vertical plate of the constraint box;

[0066] Then, the reinforcing cover plate 900 is symmetrically arranged on the top of the constraint box, and the conversion base 200 and the constraint box are reinforced and connected through the reinforcing cover plate 900; at this time, the reinforcing cover plate 900 longitudinally compresses and limits the lower cover plate 220 of the conversion base 200, so that the lower cover plate 220 of the conversion base 200 always abuts against the elastic deformation assembly of the constraint box, further limiting the elastic deformation assembly between the lower cover plate 220 of the conversion base and the constraint box, and the stability of the multi-dimensional vibration isolation support in application can be greatly improved.

[0067] At the same time, the elastic deformation assembly is located in the constraint box, the lower cover plate 220 of the conversion base 200 is compressively arranged on the elastic deformation assembly, the lower cover plate 220 of the conversion base 200 is tightly matched with the inner wall of the cavity of the constraint box to form limiting in the horizontal direction, and the lower cover plate 220 of the conversion base 200 is compressed and limited by the reinforcing cover plate 900 in the longitudinal direction, so that the elastic deformation assembly and the conversion base 200 are reliably and tightly connected in series in the constraint box.

[0068] Then, the bottom end of the horizontal vibration isolation support 100 is rigidly connected with the upper cover plate 210 of the conversion base 200 through the connecting bolt, and the upper end of the horizontal vibration isolation support 100 is symmetrically provided with a plurality of first anchors, which are connected with the equipment upper structure 700.

[0069] In this way, the horizontal vibration isolation support 100, the conversion base 200 and the elastic deformation assembly in the constraint box form a series structure, and the three are connected in series as a whole; the upper horizontal vibration isolation support has small lateral stiffness and can produce large deformation under the action of horizontal earthquake or vibration, so that the transmission of horizontal force upward can be greatly reduced; and the lower elastic deformation assembly can reduce the upward transmission of high-frequency vibration under the action of vertical vibration, so that the multi-dimensional vibration / isolation effect is realized, and the problem of simultaneously controlling horizontal earthquake and vertical vibration is solved.

[0070] The multi-dimensional vibration isolation support can realize the function of isolating horizontal earthquake action through the horizontal vibration isolation support, can isolate the propagation of vertical vibration through the vertical vibration isolation spring and the vibration isolation rubber, and finally can realize the function of three-dimensional vibration isolation, effectively controls the vibration of mechanical equipment or buildings caused by vertical vibration, and avoids the influence of vibration on the mechanical equipment or buildings or the discomfort of people in the buildings.

[0071] The above embodiment is only one of the implementation manners capable of realizing the technical scheme of the present application, and the protection scope of the present application is not limited to the embodiment, but also includes any changes, substitutions and other implementation manners easily thought of by those skilled in the art within the technical scope disclosed by the present application.
