The invention provides a barrier-free rope-falling prevention device. The barrier-free rope-falling prevention device comprises a fixed support and a supporting plate, wherein the upper end of the fixed support is fixed to a cross beam; the cross section of the supporting plate is in a V shape, and the included angle between the two inclined sides of the supporting plate is an acute angle; one inclined side of the supporting plate is fixed to the fixed support, an opening of the supporting plate faces the position above the opening, and the inner side faces of the two inclined sides of the supporting plate are provided with a circular arc surface I and a circular arc surface II in the length direction respectively. The supporting plate is located below a pulling rope after being mounted; when the pulling rope falls off, the pulling rope falls into the supporting plate through the opening of the supporting plate since the supporting plate is in the V shape. Because the inner side faces of the two inclined sides of the supporting plate are provided with the circular arc surface I and the circular arc surface II in the length direction respectively, on the condition that the pulling rope does not stop moving, a rope gripper and a hanging chair can move across the circular arc surface I and the circular arc surface II. The situation that when the pulling rope falls off, an aerial passenger device does not stop for some reasons, the pulling rope still runs to drive the rope gripper and the hanging chair to collide with the rope-falling prevention device, and then people are injured is effectively prevented.
