New Technology for Repairing Wear on Curved Rails of Bottom-Dump Mine Car Unloading Stations
This paper introduces an innovative method for maintaining the curved rails used in bottom-side discharge stations for mine cars.The method involves attaching multiple smaller-diameter rods in parallel to the worn surface of the curved rail and utilizing CO gas-shielded welding technology for cladding.This process ensures a smooth surface between the cladded rods and their surroundings,achieving a gradual transition along the length where it interfaces with the uncladded portion of the curved rail,thereby enabling smooth operation during the discharge of bottom-side mine cars.Practical application results demonstrate that this method can effectively extend the service life of the curved rails,reduce maintenance frequency and costs,and yield significant economic and social benefits.
