Method for replacing anchor mouth when ship berths at wharf

Abstract

The invention relates to a method for replacing an anchor mouth of a ship. According to the method, a construction platform is built on a wharf in advance according to the height position and the width position of the anchor mouth away from a ship deck; fixing the ship at the edge of the wharf by using a mooring rope after the ship berths at the wharf; the construction platform is hoisted to the side where the anchor mouth needs to be replaced through a crane; the upper end of the construction platform is welded and fixed to the deck face, and the lower end of the construction platform is arranged below the anchor mouth; removing the crane; anchor mouth dismantling and replacing construction is conducted; mounting an anchor; after construction is finished, the construction platform is hoisted by a crane, and a fixing point of the construction platform and the deck bulwark is cut off; the construction platform is removed by the crane; and the cut-off point at the bulwark of the deck is polished to be smooth and is coated with paint. The anchor mouth is replaced by berthing the ship at the wharf, the problem that the ship must enter the dock to replace the anchor mouth in the traditional construction process is solved, the construction period is shortened, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a method for replacing an anchor lip when a ship berths at a wharf. Background technique [0002] In the process of ship construction, the anchor lip is located at the outlet of the outer plate of the anchor chain tube, and is connected and fixed on the outer plate by the anchor boss. The collision and friction of the anchor make it stable and obedient in the oval ring structure of the anchor lip. The anchor lip is easily damaged after frequent improper use. If an accident occurs during the operation of the ship, the anchor lip needs to be replaced. [0003] Under normal circumstances, you can only dock at the dock first, wait for the right time to enter the dock or floating dock, and then set up scaffolding or use other equipment in an anhydrous state outside the ship. Patent No. CN110877682A discloses a kind of ship. Balanced anchor lip pre-installation process, which includes cons...
