High-speed rail sound barrier convenient to overhaul and maintain

Abstract

The invention relates to the technical field of high-speed rail sound barrier maintenance, in particular to a high-speed rail sound barrier convenient to overhaul and maintain, which comprises a stand column bottom plate and a connecting assembly, the connecting assembly comprises a bolt hole formed in the stand column bottom plate, and a U-shaped bolt is inserted in the bolt hole; the sealing assembly is used for sealing gaps among the U-shaped bolt, the nut, the lock washer and the bolt hole; and the anti-loosening maintenance assembly comprises a mounting frame fixedly mounted on the sound barrier stand column, a plurality of maintenance boxes are rotationally mounted on the bottom wall of the mounting frame, a plurality of clamping plates are mounted in the maintenance boxes, a maintenance rod is arranged on a fixing ring, and a silencing part is arranged above the mounting frame. Corrosion prevention and sealing are achieved by arranging the sealing assembly and adding various coatings to the connecting positions of the bolts, the anti-loosening maintenance assembly is further arranged, external air vibration and air flow are used for assisting the maintenance box to rotate, clamping plates are driven to rotate to reinforce connection of the bolts, loosening of the bolts is prevented, manual maintenance is replaced, and the maintenance cost is reduced.
