Underground transfer device

An underground transfer device comprises a crawler-type walking mechanism, an anti-collision induction mechanism and a multi-directional damping mechanism, and the multi-directional damping mechanism comprises a rectangular lower fixing plate, an upper fixing plate and a damping assembly; the damping assembly comprises a plurality of first damping springs, second damping springs and third damping springs; the first damping springs are fixed to the four corners of the lower fixing plate and the four corners of the upper fixing plate in the vertical direction correspondingly. Two second damping springs distributed in the connecting line direction of the two first damping springs are arranged between any two adjacent first damping springs, and the two corresponding second damping springs are in a V shape. The third damping springs are distributed in the advancing direction, one ends of the third damping springs are fixed to the upper fixing plate, and bolts are arranged at the other ends of the third damping spr
