The invention discloses a rope alignment device and a tower crane. The rope alignment device comprises a support and a horizontal shaft which is arranged on the support and is parallel to the axis of a winding drum; the rope alignment device also comprises a rolling device and a pulley; the rolling device comprises a rolling installation frame and a rolling wheel group which is arranged on the rolling installation frame; the rolling device is arranged on the horizontal shaft through the rolling wheel group in a rolling mode; the pulley is arranged on the rolling device through a center shaft; the center shaft is parallel to the axis of the winding drum. The tower crane comprises the rope alignment device. The pulley is driven by the rolling device to move along the axial direction of the horizontal shaft in a reciprocating mode, the pulley only needs to rotate, and accordingly the friction resistance of the pulley is small and the guide effect is good. The rolling device is arranged on the horizontal shaft in a rolling mode, a lubrication medium does not need to be added to the horizontal shaft for lubrication, and accordingly the influence of the sand wind, the cold weather and the like on the rope alignment device is small and the good guide effect can be always ensured.
