Wall climbing device for overhauling wind power tower

The utility model provides a wall climbing device for overhauling a wind power tower. The wall climbing device comprises a power sliding block, a bearing bin, a first track semi-ring and a second track semi-ring. The first track semi-ring and the second track semi-ring are used for surrounding the wind power tower to form a fixed form, so that the influence of vortex generated by high-altitude wind and wind power blades on a wall climbing device is avoided, and the safety of maintenance work is ensured; and meanwhile, the winch pulls the stair climbing device to achieve height lifting, the power sliding block drives the bearing bin to move at any position on the outer surface of the wind power tower along the sliding rail, and the overhaul work efficiency is effectively guaranteed. 本实用新型提供的一种风电塔检修用爬墙器，包括有动力滑块、承重仓、第一轨道半环及第二轨道半环；本实用新型利用第一轨道半环、第二轨道半环围绕风电塔形成固定形态，避免了高空风及风电叶片产生涡流对爬墙器的影响，保证了检修工作的安全性；同时卷扬机拉动爬楼器实现高度的升降，动力滑块带动承重仓沿滑轨可实现在风电塔外表面任意位置的移动，有效的保证了检修工作的效率。
