Abstract

The invention provides a power transmission tower cross arm structure with vibration reduction and energy consumption functions. An energy consumption element is formed through a spring-damper combined component, the effect of consuming vibration energy transmitted by a main material of a power transmission tower body is achieved, and the overall dynamic response of the tower body is reduced; in addition, the spring-damper combined component, an upper chord, vertical rods, inclined rods and a lower chord jointly form a new energy consumption system of the cross arm structure, a plurality of sets of vertical rods and inclined rods are connected in an end-to-end abutting mode and arranged between the upper chord and the lower chord in a staggered mode, and thus the cross arm structure has the using function; and in addition, the upper chord, the lower chord and a gusset plate are movably connected, thus the whole system is easy to install, has high structural safety and high reliabilityand does not affect the using function of a cross arm.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a cross-arm structure of a transmission tower for vibration reduction and energy consumption. Background technique [0002] At present, in order to effectively ensure the safe operation of transmission lines, the method of reducing the structural vibration response of transmission towers is usually used, and the measures to reduce the structural vibration of transmission towers include hanging mass pendulums, using bonded elastic materials, and improving the stiffness of transmission tower components. , these measures can reduce vibration to a certain extent, thus ensuring the safe operation of transmission lines. [0003] However, measures to increase the stiffness of components are not an economical solution, and they are not self-adaptive; using the vibration reduction solution of bonded elastic materials, the materials are very prone to aging phenomena during use, ...
