Repulsion type magnetic suspension shock insulation supporting base and manufacturing construction method thereof

Abstract

The invention provides a repulsion type magnetic suspension shock insulation supporting base and a manufacturing construction method thereof. The repulsion type magnetic suspension shock insulation bracket supporting base comprises a structure loading-bearing means. A repulsion type magnetic device is arranged below the structure loading-bearing means. The repulsion type magnetic device comprises an upper electromagnet and a lower electromagnet, wherein the upper electromagnet and the lower electromagnet are arranged in the longitudinal direction and wound with electric wires. The arrangement of the electric wires guarantees that repulsion force is produced when the upper electromagnet and the lower electromagnet are charged with electricity. The upper end of the upper electromagnet is fixedly connected with the lower end of the structure loading-bearing means. The lower end of the upper electromagnet and the upper end of the lower electromagnet are provided with a concave face and a convex face which are matched with each other. The lower end of the lower electromagnet is fixed to a sliding and transferring supporting seat capable of insulating horizontal earthquakes; and the sliding and transferring supporting seat is fixed to a construction foundation. The repulsion type magnetic device insulates vertical vibration, so that the suspension force is large, both alternating current and direct current can be adopted, the size of the device is small, the cost is low, a special controlling regulating system is not needed, and the vibration insulating effect is good.

Description

technical field

[0001] The invention relates to an engineering structure damping device and a manufacturing and construction method thereof, in particular to a repulsion-type magnetic suspension shock-isolation support and a manufacturing and construction method thereof. Background technique

[0002] Magnetic suspension vibration isolation is a new type of active vibration isolation method. It is supported by an actively controlled magnetic field between the vibration source and the structure, so that the vibration source and the structure are completely separated from mechanical contact to achieve the purpose of isolating vibration. Magnetic suspension vibration isolation technology has been successfully used in aerospace, navigation, railway transportation, wind power generation and other fields, but it has not been used in civil engineering. This application is a specific implementation device of the patent "Technical Application of Magnetic Suspension in the Field of Ant...
