二、背景技术2. Background technology

为保证输电线路供电连续性和可靠性,运检人员需及时带电更换不合格绝缘子。然而,带电更换直线绝缘子串的传统方法是使用滑轮组,但该方法只适用于小档距直线杆塔。如遇到大跨越、大档距情况时,使用滑轮组需要大量的人力物力,难以完成更换工作,甚至有绳索断裂、导线掉落地面的风险。因此,探索一种可以代替更换大跨越、大档距直线绝缘子串的提升器,对减少导线掉落地面的风险和降低人力物力投入势在必行。 In order to ensure the continuity and reliability of the power supply of the transmission line, inspection personnel need to replace unqualified insulators in a timely manner. However, the traditional method of live replacement of linear insulator strings is to use a pulley block, but this method is only suitable for small-gage linear towers. In the case of large spans and large spans, using a pulley block requires a lot of manpower and material resources, making it difficult to complete the replacement work, and there is even a risk of the rope breaking and the wire falling to the ground. Therefore, it is imperative to explore a lifter that can replace the replacement of long-span and large-gap linear insulator strings to reduce the risk of wires falling to the ground and reduce the input of manpower and material resources.
