Frog vertical abrasion and crushing one. ⑴ wheel causes the heart from harmful space frog wing rail through the transition, or transition from the wing rail to the heart of the tracks, under the impact of the role in the larger wheels, wing rail and rail center will produce serious wear and injury is. ⑵ abrasion and injury is often occurs in the bend of the wing rail and rail center section at 30 ~ 40mm, because here by wheel vibration collision forces are relatively large. ⑶ frog heart often happens at the sleeper hanging plate, when the high-speed train through the frog will appear along with the ups and downs under the pillow fork vibrate, thus undermining the track bed in the lower part of the foundation of a solid resistance, causing poor drainage, mud pumping in aggravated a severe abrasion upper wing rail and rail and heart damage. Use regular maintenance experience accumulated in the bottom of turnout frog pillow top surface pad pads to cushion the force mine life with the turnout, the Director of frog and turnout sleepers. In order to maintain the overall stability of the mine with the turnout frog plant, manganese between the frog and the entire cast sleeper screw spike required fixed. ⑺ bottom rail combination of frog and around joints, should be laid large plate and bridge-plate joints with vertical bolts and plates fixed on the frog plate, such as AT Mine turnout turnouts as procurement, strengthen frog overall stability. In parts of the fork frog pillow Mine turnout specifications, install a special iron base, with shells of Ⅰ type fastener fixed frog position. Elastic fastening buckle pressure, can prevent sliding frog, but will also prevent vertical climb on solid frog can achieve better results.
