The invention discloses a mooring rope device for ship parking. The mooring rope device comprises a hollow column, a rotating shaft, a rope winding wheel, a mooring rope, two reset springs, a limitingmechanism and an outlet sleeve, wherein the top end and the bottom end of the rotating shaft are inserted into bearings embedded in the top and the bottom of the inner wall of the hollow column, therope winding wheel sleeves the rotating shaft, the mooring rope winds the rope winding wheel, the two reset springs sleeve the upper end and the lower end of the rotating shaft, the two opposite endsof the two reset springs are fixedly connected with the top and the bottom of the rope winding wheel, one ends of the two reset springs are fixedly connected with the top and the bottom of the inner wall of the hollow column, and the limiting mechanism is arranged on the hollow column. According to the mooring rope device, the mooring rope can be pulled out from an outlet sleeve, the reset springsare compressed and coiled, and when the circular projection is separated from an arc-shaped plate, the reset springs can rotate back under the condition that the resistance is lost, and the outer mooring rope can wind the rope winding wheel again.
