Embodiment Construction

[0038] Such as Figure 1 to Figure 8 As shown, for existing defects, the subject of protection of the present invention is as follows:

[0039] The anti-overturning high-voltage transmission line tower is developed. In the anti-seismic unit of the tower, the middle part is often bent first, causing accidents.

[0040] Through analysis, the applicant found that the cause of the accident was mostly caused by the following: the cable was fixed on the top of the iron tower, and the bottom was fixed on the foundation, so that external forces were formed at both ends. Under the action of external loads such as wind, snow, and earthquake, Iron towers will overturn, and the first bending point of more than 90% of the overturning is in the middle and lower part of the iron tower, and the bending at the foundation is relatively rare. This is because, from the perspective of force analysis, the swing of the iron tower and The static dividing line is at this position, which is prone to f...

Abstract

The invention discloses an anti-overturning high-tension transmission line iron tower used for solving the problem that an iron tower is prone to overturning. The iron tower comprises an iron tower body and a transition part, and the middle portions of the iron tower body are disconnected and movably connected through the transition part, with buffering and damping functions, on the corner. The transition part comprises a first plate, a second plate and a third plate which are arranged in parallel from top to bottom, wherein the portion between the first plate and the second plate and the portion between the second plate and the third plate are each designed to be a buffering structure with a brake structure. As the lower middle portions of the iron tower are disconnected and provided with the transition part, the portion prone to bending in the iron tower shifts in the horizontal direction in the presence of the transition part, in the shifting process, vibrating energy is consumed through effective friction, vibrating frequency and amplitude are changed, bending is avoided, the method of increasing the use amount of profile steel to improve strength traditionally is changed, and the seismic resistance is improved by 40% without changing the steel amount.

Description

technical field [0001] The invention relates to the technical field of iron towers, in particular to an iron tower installation structure for an anti-overturning high-voltage transmission line with excellent anti-seismic performance. Background technique [0002] Earthquakes have caused serious damage to various transmission lines, especially ultra-high voltage transmission lines. Due to the high voltage level, tower height and self-weight, they are prone to collapse under the action of strong earthquakes, and this collapse is often accompanied by large-scale The chain reaction caused a large area to collapse. Seismic isolation technology is a technology that has developed rapidly and has been continuously improved in the field of earthquake resistance in the past 30 years. [0003] When the magnitude of the earthquake is large or the "hard resistance" of the structure is difficult to meet the expected seismic requirements due to some reasons, the use of seismic isolation t...
