一种特高压输电线的辅助安装装置

Abstract

本实用新型提供一种特高压输电线的辅助安装装置，包括滚轴宽度调节机构、缆绳限位盘、中心固定辊轴以及驱动电机，中心固定辊轴的两端分别安装有滚轴宽度调节机构，滚轴宽度调节机构以及中心固定辊轴的圆周表面上分别安装有缆绳限位盘，该设计解决了原有装置在安装时需要依次用更粗的线拉动电缆，同时使用卷扬机将拉绳和电缆不断拉紧，而滚轮的间隙无法根据拉绳的粗细调节，在用粗细不同的拉绳拉动电缆时会导致一定角度偏移，导致安装电缆效率较低的问题，本实用新型设计一种滚轴宽度调节机构，实现能够在更换不同拉绳拉动电缆时，调节缆绳限位盘之间的宽度，从而更加贴合拉绳，保证了拉绳拉动过程中的稳定，提高电缆安装效率。
