Vibration isolation and reduction bracket for cable structures

Abstract

The invention discloses a vibration isolation and reduction bracket for cable structures, comprising a support member (1), a vibration isolator (3), a hydraulic vibration reducer (6), a spring (7), a regulating nut (5), and a connecting pedestal (4). An adjustable combined vibration reducer (B) is composed of the spring (7), the hydraulic vibration reducer (6) inside the spring and the regulating nut (5), wherein the spring (7) provides support force, stiffness and reset ability, the regulating nut (5) regulates the length of the spring (7) to ensure that there is no tensile stress at a support member the root (A) in the balanced position, and the hydraulic vibration reducer (6) plays a role in in-plane buffer, displacement control, energy consumption and vibration reduction. The vibration isolator (3) produces shear deformation and consumes energy, and can reduce out-of-plane longitudinal vibration caused by action of the support member (1). By adopting the vibration isolation and reduction bracket for cable structures, fracture or fatigue damage of the support member root (A) caused by in-plane and out-of-plane three-direction vibration is solved, the redundancy of cable structures is enhanced, and the safety and using performance of a supported structure (2) are improved.

Description

Technical field [0001] The present invention is the field of power engineering equipment, which involves a cable structure with a cable structure. Background technique [0002] When the bracket is loading in the vibration environment, especially the flexible structure with a large length such as high -voltage power cables, it will suffer the three -way vibration effect of the vertical surface between the inside and between the bracket, which will not only affect the stability of the support structure, but alsoPerformance and safety, and will increase the stress and deformation of the bracket, causing broken or fatigue damage to the root of the bracket.However, due to the needs of actual engineering and the requirements of the use conditions, the form of brackets is generally simple and practical, and low redundancy; so under the influence of the sources, the node (root) of the bracket will inevitably break or fatigue damage.Therefore, the brackets in this environment must take ...

Problems solved by technology

[0002] When the support is loaded in a vibrating environment, especially supporting a long-length flexible structure such as a high-voltage power cable, it will suffer from three-dimensional vibration in the plane and between the supports and the vertical plane, which will not only affect the stability of the supported structure, Performance and safety, and will increase the stress and deformation of the bracket, resulting in fracture or fatigue damage at the root of the bracket

However, due to the needs of actual engineering and the requirements of use conditions, the form of the support is generally simple and practical, and the redundancy is low; therefore, under the influence of the vibration source, the node (root) of the support will inevitably break or be damaged by fatigue
