Description

Technical Field

[0001] The utility model relates to the technical field of iron accessories for iron towers, in particular to an iron accessory for an iron tower of a power transmission line. Background Art

[0002] Power towers are important facilities that support high-voltage transmission lines and are an indispensable part of modern power systems. They are usually built in the wild or in cities and are responsible for the important task of transmitting electricity from power stations to various users. The design and construction of power towers need to take into account many factors, such as terrain, meteorological conditions, the length and height of transmission lines, etc. In short, power towers are important facilities that are indispensable to modern power systems.

[0003] Patent publication number "CN218216607U" discloses "a kind of iron tower iron accessory", including a lower closing plate, the top of which contacts an upper closing plate, the inner cavities of the lower closing plate and the upper closing plate are provided with a supporting mechanism, both sides of the lower closing plate and the upper closing plate are provided with semicircular grooves, the inner cavities of the lower closing plate and the upper closing plate are penetrated with cables, the top of the semicircular groove and the upper closing plate is sleeved with a U-shaped plate, and a positioning mechanism is provided between the U-shaped plate and the lower closing plate. The problem that cracks will appear in the existing iron accessories after a period of time during use is solved, mainly because the dead weight of the cable generates a large shear force on the iron accessories, and the force is concentrated at the screw hole, so that the iron accessories are unevenly stressed and cracks are generated, resulting in damage to the iron accessories and increased costs, and the iron accessories do not have an auxiliary limiting structure during installation, which makes the iron accessories poor in stability and inconvenient to install, affecting the applicability of the iron accessories.

[0004] The device in the above patent achieves a stable fixation of the cable by tightly connecting the lower closing plate, the upper closing plate and the U-shaped plate. If strong winds occur during the fixation of the high-voltage transmission line, the line may sway to a certain extent, causing the U-shaped plate with poor fixing effect to fall off. In order to improve the practicality of the device, it should be optimized and improved. Utility Model Content
