Problems solved by technology

While this arrangement works very well for many supporting structures, structures such as transmission towers with high centers of gravity and eccentricity face multi-directional load inputs that cannot be easily compensated using only traditional pedestal isolators

Abstract

The invention discloses a transmission tower base shock isolation device and an installation method thereof, and belongs to the field of transmission tower support components. The device comprises a first supporting plate, a second supporting plate, steel wire rope isolators and linear dampers. The first supporting plate is connected with a foundation, the second supporting plate is fixed to a structure to be isolated and is parallel to the first supporting plate, a gap is reserved between the supporting plates, a plurality of sets of steel wire rope isolators and at least one linear damper are arranged between the first supporting plate and the second supporting plate, and the dampers are arranged at an angle. Compared with a traditional single shock isolator, the transmission tower base shock isolation device has better applicability and stability, and the maintenance cost of the whole life cycle is low.

Description

technical field [0001] The invention belongs to the technical field of shock-isolation devices for electric transmission towers, and in particular relates to a shock-isolation device for a base of electric transmission towers and an installation method thereof, and is especially suitable for eccentric structures. Background technique [0002] Ground supporting structures or installations are susceptible to various forms of loading during their use, including seismic and environmental load inputs such as wind loads. The transmission tower is a typical structure with a high center of gravity, and in actual engineering, due to conditional constraints and functional requirements, it often presents an asymmetrical eccentric structure. Under the action of earthquake load or even wind load, the steel components that make up the transmission tower will undergo large deformation and even enter the plastic stage, which will adversely affect the performance. The time it takes to inspe...
