Grinding device for inner welding seam of U-shaped rib

The utility model discloses a U-shaped rib inner welding seam coping device which solves the technical problem that potential safety hazards are brought to later use due to the fact that local poor portions of U-shaped rib inner welding seams of orthotropic steel bridge decks cannot be coped in the prior art. The device comprises a trolley capable of self-walking on a bridge panel, an adjusting mechanism arranged on the trolley, and a grinding wheel arranged on the adjusting mechanism and used for grinding a to-be-ground part of an inner welding seam between a U rib and the bridge panel. The device is simple in structure, scientific and reasonable in design and convenient to use, can effectively and accurately grind and inspect the weld joints in the U ribs of the orthotropic steel bridge deck, and can grind the weld joints in narrow spaces in the U ribs of different specifications and inspect the appearances of the weld joints. 本实用新型公开了一种U肋内焊缝修磨装置，解决现有技术无法对正交异性钢桥面板U肋内焊缝局部不良部位进行修磨从而为后期使用带来安全隐患的技术问题。本实用新型包括可在桥
