Electric transmission line iron tower angle steel tower material replacement protection device

CHEN GUIZHOU / CAI XIANGHUI

The invention relates to the technical field of power operation tools, in particular to a power transmission line iron tower angle steel tower material replacement protection device which comprises a fixed support standing on the ground, a lifting assembly adjusted according to the position of a tower material is arranged on the fixed support, and the lifting assembly comprises a guide frame fixed to the fixed support and perpendicular to the ground. A lifting table moving along the guide frame is arranged on one side of the guide frame in a sliding mode, and a vertical frame located on one side of the guide frame is fixed to the lifting table; according to the electric transmission line iron tower angle steel tower material replacement protection device, the first protection mechanism and the second protection mechanism are used for protecting the tower body when the angle steel tower material is replaced, and the situation that the angle steel tower material is in a missing stage before the angle steel tower material is newly supplemented after the angle steel tower material is dismantled is avoided; when an iron tower is in a stress change non-protection state, the overall stress of the tower is changed, so that the stress of part of tower materials exceeds a design range, and the accident risks of tower material deformation and tower collapse exist.

本发明涉及电力作业工器技术领域，具体为一种输电线路铁塔角钢塔材更换保护装置，包括立于地面的固定支架，所述固定支架上设置有根据塔材位置而调整的升降组件，所述升降组件包括与固定支架固定且与地面垂直的导向架，所述导向架的一侧滑动有沿着导向架移动的升降台，所述升降台上固定有位于导向架一侧的竖直架；本发明的目的在于提供一种输电线路铁塔角钢塔材更换保护装置，利用第一保护机构以及第二保护机构在更换角钢塔材时对塔身起到保护作，避免拆除角钢塔材后新补装角钢塔材前角钢塔材处于缺失阶段，铁塔处于受力变化无保护状态，杆塔整体应力发生改变，导致部分塔材受力超出设计范围，存在塔材变形及发生倒塔的事故风险。
