电力线路维护中受力监测紧线器的设计

Design of Stress Monitoring Tighteners for Power Line Maintenance

摘要: 针对目前电网作业中传动紧线器在牵引过程中，因受力过载发生安全问题，研制一种适用于电力线路的维护、检修的具有受力监测功能的新型紧线器。本文首先阐述了紧线器的基本结构和原理，同时采用ANSYS Workbench仿真软件对螺栓连接承拉板件的强度进行验算，基于紧线器施工特性和吊钩及连接部件的受力特点，采用基于电阻应变式测量原理制作开孔为M24螺纹孔的S型拉压受力传感器进行数据的采集和处理。最后，根据拉力传感器的结构确定连接金具的外形结构，决定采用40 Cr工具钢材料进行连接金具外壳的制作，完成带有受力监测功能的紧线器。

Abstract: Aiming at the current power grid operation transmission tightener in the traction process, due to the force overload occurring safety problems, the development of a suitable one for the maintenance of power lines, and overhaul with the force monitoring function of the new tightener. This paper first explains the basic structure and principle of the tightener and, at the same time, adopts ANSYS Work-bench simulation software to calculate the strength of the bolt connection bearing plate parts, based on the construction characteristics of the tightener and the force characteristics of the hooks and connecting parts, adopts based on the principle of resistance-strain measurement to make the S-type pulling and compression force sensors with the opening of M24 threaded holes for the acquisition and processing of data. Finally, according to the structure of the tension sensor to determine the shape of the connecting fixture, it was decided to use 40Cr tool steel material for the production of the connecting fixture shell, to complete the tightener with the function of force monitoring.
