The invention discloses an underground type transfer device for a high-speed railway platform. The underground type transfer device is characterized by comprising a connecting transmission device, a vertical transport passage, an underground freight transport passage, and an underground freight sorting room; and the underground transfer device can transport freight to be unloaded of a high-speed rail train on the ground level of the platform to the underground, and the freight to be loaded from the underground to the high-speed rail train on the ground level of the platform; the separation ofpassengers and freight is realized; the passenger transport and the freight transport do not interfere each other; and the utilization rate of the high-speed railway platform is improved.
