新型架空线路防坠落装置用自锁器研制

Development of a New Type of Self-locking Device for Anti-falling Device Applied in Overhead Lines

针对架空线路防坠落装置T型导轨用自锁器现场使用需求,对自锁器机械结构及特性进行了研究。设计了自锁器的导向和拆卸结构方案,进行了仿真计算,生产了样机,通过了实验室力学试验验证,并在架空线路现场进行了应用试验。在保证自锁器安全性的基础上,使自锁器具备了拆卸功能,并提高了现场适用性能,解决了一线登塔人员的使用难题。

In allusion to the field application needs of self-locking devices for T-shaped guide rails applied in the anti-falling protection devices for overhead lines,the mechanical structure and characteristics of the selflocking devices are studied,a guiding and dismantling structure scheme for such a self-locking device is designed followed by simulation calculations and prototype production,which is verified by mechanical tests in labs and application tests carried out at the site of overhead lines.On the basis of ensuring the safety of the self-locking device,it also possesses the function of disassembly,which improves the on-site applicable performance,and solves the difficulties the first-line tower climbers are faced with.
