Abstract

The invention discloses a lattice type power transmission tower horizontal vibration self-reset shock absorber which comprises shape memory alloy rings, a steel ball, an anchor bolt, a steel suspension rod and a steel suspension ring, wherein the lower end of the steel suspension rod is fixedly connected with the steel ball; the upper end of the steel suspension rod is fixedly connected with the steel suspension ring; the steel suspension ring is hung at the top center of a power transmission tower; four shape memory alloy rings are provided and anchored at the four corners of the tower body of the power transmission tower; the four shape memory alloy rings are all horizontally arranged and uniformly distributed around the periphery of the steel ball; the centers of the four shape memory alloy rings are located on the circumference of the same circle centered on the steel ball; the steel ball absorbs shock and consumes energy by use of the shake thereof in the case of small amplitude; and in the case of large amplitude, the steel ball can collide with the shape memory alloy rings to consume energy so as to realize shock absorption.

Description

technical field [0001] The invention relates to vibration damping equipment belonging to civil engineering, in particular to a self-resetting damper for horizontal vibration of a lattice type transmission tower. Background technique [0002] The transmission tower line system is the carrier of high-load electric energy transmission and an important lifeline engineering structure. With economic development, scientific and technological progress and increasing awareness of environmental protection, the demand for electric energy in industrial production and residents' life has grown strongly. The project scale of the transmission tower line system is gradually becoming larger, the structure is complex and changeable, and the project cost index is greatly increased. Therefore, new requirements are put forward for the structural design theory and disaster prevention and mitigation of power lifeline engineering to ensure the safety of its use. Stability and stability have become...
