Based on the practical project，the reasons for the looseness and fall of the rail pressure plate of the unloading trolley in the steel gallery at the port of the coal silo，the local wear of the rail，the gap between the expansion joints of the rail，the left and right displacement，and the vertical elevation difference exceeding the standard are analyzed. The flexible track fixing system and high-speed rail track fixing system are compared and studied with the traditional unloading trolley track fixing system. The results show that no matter which track fixing system is used，the track fasteners need to be regularly inspected and maintained. Under heavy loads or when the use frequency is high，flexible track fixing systems should be given priority to extend the maintenance-free time of the track.
