Working principle and necessity of tamping

As the train moves and exerts great impact on the track and sleepers, the impact force is transmitted to the road bed ballast. The friction between the ballasts gradually produces irregular ballast gaps, which makes the locomotive transit gradually more bumpy and the safety is greatly reduced. Therefore, the ballast must be tamped regularly to improve the safety of train transportation. The basic requirement is for the ballast to have the following functions:

Has enough strength to bear the pressure of sleepers

Dense enough to provide sufficient force to hold the sleepers in place

Resistant to temperature changes and water erosion

The hydraulic tamping machine uses an electric motor or an internal combustion engine (gasoline engine or diesel engine) as the prime mover, and drives the oil pump through a belt drive to generate hydraulic oil. The pressure oil enters the working cylinder through the reversing valve, thereby lifting or opening and closing the tamping pick. At the same time, the prime mover drives the vibration shaft to rotate at high speed through another belt drive, causing the tamping pick to vibrate. After the vibrating tamping pick is inserted, the ballast is vibrated, causing the mutual friction resistance to be reduced or overcome, causing the ballast to assume a "flow state". Therefore, the ballast is rearranged in the relative motion, and coupled with the clamping effect of the tamping pick during the clamping action, the ballast under the pillow is dense.
