The rail bottom welding track milling machine is a special small machine to remove the rail bottom welding track after the rail welding tumor, which can remove the residual amount of the rail bottom welding track with high quality and high efficiency, and achieve
the purpose of repairing the welding track.
Railway rail weld after welding according to the requirements for grinding, the rail head, rail waist, rail bottom slope parts have special grinding machine, and because of the small space at the bottom of the rail bottom, personnel cannot observe the limitations, the field grinding are artificial groping grinding, grinding quality is low efficiency, this product to fill the part of the blank without special equipment.
This product proposes the dressing method of milling instead of grinding, using the working mode of one positioning and disposable cutting, which can quickly remove the pushing margin of the rail bottom, achieve the purpose of leveling the rail bottom welding path, greatly improve the work efficiency, and reduce the labor intensity of personnel.
Working principle: extend the front part of the holder into the bottom of the rail, and move the lock and moving rod to fix the equipment at the bottom of the rail. After starting the engine, adjust the maximum throttle, the clutch is combined with the power transmission to the speed reduction box, and then transmitted to the milling cutter spindle through the sprocket chain. The milling cutter runs quickly and shakes counterclockwise into the hand wheel for milling. After milling, turn the handwheel clockwise and return. Turn off the engine and remove the equipment to a safe area.
