Description

Technical Field

[0001] The utility model relates to a power iron tower base structure and belongs to the technical field of power iron towers. Background Art

[0002] Transmission line towers are tower-shaped buildings used for power transmission. Their structural characteristics are that all types of towers are space truss structures, and the rods are mainly composed of single equilateral angle steel or combined angle steel. In recent years, with the rapid growth of the national economy, the power industry has developed rapidly, which has promoted the rapid development of the transmission line tower industry.

[0003] For example, CN214740360U discloses an adjustable power tower base with good stabilization effect. When the vibration is transmitted to the inside of the base, the base transmits the impact force generated by the vibration to the buffer spring, and the buffer spring absorbs a large amount of the impact force generated by the vibration, so that when the buffer spring transmits the impact force to the power tower, only a small part of the remaining impact force remains, which cannot cause impact damage to the power tower itself, thereby reducing the maintenance cost of the power tower. However, the fixed rod and the fixed plate support the bottom of the tower, and when the tower is stressed, the support force on the top of the tower is insufficient. In addition, the power tower is inevitably tilted during long-term operation due to natural factors such as wind, rain, snow and surface runoff. Since the height of the base cannot be adjusted, it is easy to cause the center of gravity of the tower to shift, which has certain safety hazards. Utility Model Content
