The invention discloses high-strength rail trolley
wheel train sets. A bearing plate and the N
wheel train sets installed on the bearing plate through a translation mechanism are included, and N is larger than or equal to 3. In the using process, the N
wheel train sets are hung on a rail, when rail replacing needs to be carried out, parts of the wheel
train sets are derailed at the same time and then moved to an adjacent rail through rail replacing, then the remaining wheel
train sets are subjected to rail replacing, then a
carriage below the bearing plate is moved to the adjacent rail throughthe translation mechanism, and therefore left-right translation of a rail trolley is achieved. According to the high-strength rail trolley wheel
train sets, through the arrangement of a walking wheelsystem and a climbing mechanism, the rail trolley can vertically walk up and down along the rail, press the rail to walk and
walk in a hanging manner under the rail. The high-strength rail trolley wheel train set and the rail replacing method have the beneficial effects that high-precision walking of the rail trolley can be achieved; by arranging ABC
gear train sets, the
stress point can reach 80%-100%, the coverage area is wide, the
carriage can be lengthened along with the rail, adaption to large-scale transportation is achieved, the efficiency is high, and the economic value is wide.
