Description

Technical Field

[0001] The utility model relates to the technical field of power transmission equipment, in particular to a rest platform for a power transmission iron tower and a power transmission iron tower. Background Art

[0002] Transmission towers are tower structures used to support high-voltage transmission lines. They are an important part of the power system and are used to transmit electricity from power stations to various power consumption areas. The structural characteristics of transmission towers are that various tower types are space truss structures, and transmission towers are installed outdoors, so they need to withstand wind and rain. In order to ensure the stability of transmission towers, when transmission towers are used, reinforced structures are required to fix and support them. For higher transmission towers, operators need to climb to the top of the tower or a specific position on the tower body when performing maintenance, inspection or installation work. The existence of a rest platform allows workers to rest and reduce fatigue during the climbing process. It can reduce the risk of operational errors and falls caused by fatigue, can serve as a temporary shelter in an emergency, can be used as a place to store tools and equipment for easy access, and can provide a kind of psychological comfort for workers working at heights; however, the rest platforms in the prior art still have some shortcomings, such as a rest platform for an electric tower disclosed in patent No. CN202320363175.3, which fixes the rest platform to the outside of the tower, greatly increases the wind resistance of the tower itself, affects the force and structural stability of the tower, and when the rest platform is installed on the outside of the tower, the installation and maintenance difficulties are relatively high, and the safety and practicality are insufficient.
