Sand belt type rail welded rib polishing device and sand belt type rail welded rib polisher

Abstract

The sand belt type rail welding rib polishing device and sand belt type rail welding rib polishing machine disclosed by the specification relate to the technical field of welding rib polishing. The device comprises a fixed support, a driving wheel, a polishing sand belt and a polishing structure. The polishing structure comprises a polishing wheel, a rotating shaft, a connecting frame and two protective pieces. The driving wheel is connected with the fixed support. The polishing sand belt is sleeved outside the driving wheel and the polishing wheel. The connecting frame is fixedly connected with the fixed support. The two ends of the rotating shaft are both connected with the connecting frame. The polishing wheel is sleeved outside the rotating shaft, and the polishing wheel can rotate around the rotating shaft. The two protective pieces are arranged at the two ends of the polishing wheel, and the protective pieces are arranged separately from the polishing wheel. The strength of the protective piece is greater than the strength of the polishing sand belt and less than or equal to the strength of the rail. It can be seen that, by arranging the protective piece separately from the polishing wheel, the protective piece can rotate without the polishing wheel under the premise of avoiding excessive polishing, reducing the damage to the rail during the polishing of the welding rib, and improving the safety.
