The invention discloses a rope-aligning device for a tower crane. The rope-aligning device comprises two vertical U-shaped hole installation ear plates (5) arranged on the bottom surface of a balance arm transverse beam (2), a rope-aligning wheel (4) arranged between the two plates, and a rope-aligning shaft (1) connecting the vertical U-shaped hole installation ear plates (5) with the rope-aligning wheel (4) in a penetrating way, wherein an open U-shaped hole (51) is formed in the U-shaped hole installation ear plates (5) respectively; the U-shaped holes (51) can be used for accommodating the rope-aligning shaft (1); the openings of the holes are movably enclosed through connection installation clamping plates (3) connected with both sides of the openings. The installation way of the rope-aligning wheel of a lifting mechanism is changed, and the rope-aligning shaft is arranged from the U-shaped holes in the side faces of the U-shaped hole installation ear plates instead of inserting the rope-aligning wheel from a circular hole in a side ear plate, so that limitation on the installation space is eliminated, the length of the rope-aligning shaft is further increased, and the rope-aligning effect and installation convenience are enhanced.
