500 kV输电线路导线检修作业平台固定架设计

Design of Fixed Frame for Conductor Maintenance Platform of 500 kV Transmission Line

摘要:

通过对历年来输电线路导线检修作业的分析，发现人工走线等检修存在作业风险，如作业人员在导线上无法保持平衡发生侧翻的风险、导线压接管加强预绞丝缠绕难度大等问题。为控制上述风险，文中设计了一种输电线路导线检修作业平台固定架，主要包括主骨架设计、子导线线间距调节功能设计、上下物件传递功能设计、导线上移动功能设计，并且完成了应用效果确认。通过所设计固定架能防止子导线距离过大，有效辅助作业人员完成导线上的工作，降低人员的安全风险，提高了人员在导线上的工作效率。

Abstract:

Through the analysis of maintenance operation of transmission line conductor over the years, it is found that there are operation risks in manual wiring and other maintenance, such as the risk of rollover caused by the operators′ inability to maintain balance on conductor, and the difficulty of strengthening the pretwisted wire winding of conductor crimping pipe. In order to control the above risks, a fixed frame for conductor maintenance operation platform of transmission line is proposed, and the design schemes, mainly including main skeleton, sub conductor spacing adjustment function, up and down object transmission function and conductor up movement function are given, which has completed the confirmation of application effect. The designed fixed frame can prevent the distance between sub conductors from being too large, effectively assist the operators to complete the work on conductors, reduce the safety risk and improve the work efficiency on conductor.
