Abstract Aiming at the problem of fast wear and frequent replacement of the reversing pulley in the practical application of the overhead passenger device, this paper takes the RJY35 type overhead passenger device of 102 roadway in Maozequ Coal Mine as the research object, and analyzes the wear problem of the reversing pulley through the simulation analysis method. The problem of stress distribution is clarified, and the multi-objective genetic algorithm is used to optimize and improve the reversing pulley. The practice shows that the optimized reversing pulley effectively reduces the problems of high stress value and stress concentration, and the wear condition is alleviated, which improves the production efficiency of coal mine, ensures the safety of underground transportation, and provides experience for the optimization of coal mine equipment under similar conditions.
