The method comprises the following steps that a, a hinge type linkage movable platform is manufactured; b, a hinge lifting lug is installed at the outboard position of a deck on the dock wall top of the floating dock; c, the ship to be repaired is berthed outside the dock wall outboard of the floating dock and is moored with a cable; d, using a crane on the dock to hoist the hinge type linkage movable platform to be installed on the outboard hinge lifting lug of the deck on the top of the dock wall; e, the dock crane is used for hoisting and installing the boarding ladder to a lifting lug at the front end of the hinge type linkage movable platform, and after sealing, the other end of the boarding ladder falls on a living quarter deck of the outboard ship; and f, after repairing construction of the ship to be repaired is completed, the ship boarding ladder and the hinge type linkage movable platform are hoisted and detached through a crane on the dock, and the ship is placed on a deck on the dock wall top. The problem that the dock crane interferes with the boarding ladder during operation and walking is solved, the boarding ladder only needs to be disassembled and assembled once, the use requirement during ship repair is met, the use efficiency of the dock crane is improved, and the smoothness of a channel is improved.

Description

Technical Field

[0001] The invention relates to the field of repairing ships moored outside a floating dock, and in particular to a method for setting up a boarding ladder after a ship is moored outside a floating dock. Background Art

[0002] After a period of operation, ships need to be repaired in order to meet the requirements of maintaining ship class seaworthiness. In recent years, the ship repair market has exploded. In order to increase efficiency, some ships choose to dock at the floating dock for overboard mooring for repair. During the repair period, it is necessary to set up a boarding ladder between the top deck of the floating dock wall and the ship to be repaired to meet the needs of construction personnel for boarding and disembarking and emergency. The crane of the floating dock also walks on the top deck of the dock wall for construction work. The dock crane interferes with the boarding ladder during operation. The boarding ladder needs to be frequently dismantled and reinstalled, and the boarding ladder also needs to be hoisted and dismantled and installed by the dock crane, which seriously restricts the use efficiency of the dock crane and the smoothness of boarding and disembarking of construction personnel, greatly reduces the efficiency of ship repair, and thus increases the repair cycle of the ship. In order to reduce costs and increase efficiency, shorten construction period, and improve competitiveness, a method of setting up a hinged overboard boarding ladder after the ship is docked overboard of the floating dock is needed to solve this construction problem. Summary of the invention

[0003] The purpose of the present invention is to provide a method for setting up a boarding ladder after a ship is docked on the outside of a floating dock, which does not affect the movement of a crane on the dock, meets the effective unobstructedness of the boarding ladder, and avoids the risk of a hinged platform and the ship scraping against each other during the process of the outboard ship docking on the outside of the floating dock.

[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a method for setting up a boarding ladder after a ship is moored outside a floating dock, comprising the following steps: a. Make a hinged link activity platform; b. Install hinged lifting lugs on the outboard side of the top deck of the floating dock wall; c. Dock the vessel to be repaired at the floating dock wall and moor it with cables outside the side; d. Use the dock crane to hoist the hinged link movable platform and install it on the outboard hinge lug of the top deck of the floating dock wall; e. Use the dock crane to lift and install the boarding ladder to the lifting lug at the front end of the hinged movable platform. After sealing, the other end of the boarding ladder falls onto the living area deck of the outboard ship; f. When the repair of the ship to be repaired is completed, the boarding ladder and the hinged movable platform are hoisted and removed by the dock crane and placed on the top deck of the dock wall to complete the erection and removal of the outboard boarding ladder of the ship to be repaired.

[0005] In the step d, the hinged link movable platform is fixed on the hinge lifting ear by means of a sealing pin.

[0006] In the step d, two sealing pins are installed at the outboard hinge ears of the top deck of the floating dock wall.

[0007] In the step e, the boarding ladder is fixed to the lifting lug at the front end of the hinged movable platform through a sealing pin.

[0008] The present invention discloses a method for setting up a boarding ladder after a ship is moored outside a floating dock, which solves the problem of interference between the dock crane and the boarding ladder during operation. The boarding ladder only needs to be disassembled and assembled once, and can fully meet the use requirements during ship repair, thereby greatly improving the use efficiency of the dock crane, and also improving the smoothness of the passage and the competitiveness.

[0013] like Figures 1 to 3As shown, the method for setting up a boarding ladder after a ship is docked outside the floating dock comprises the following steps: a. making a hinged link movable platform 5; b. installing a hinged lifting lug 4 outside the top deck 2 of the floating dock wall; c. after the ship to be repaired 9 is docked outside the floating dock wall 1 and moored with a cable; d. using a dock crane 3 to hoist the hinged link movable platform 5 to the hinged lifting lug 4 outside the top deck 2 of the floating dock wall, and fixing the hinged link movable platform 5 with a sealing pin 6; e. then using the dock crane 3 to hoist the boarding ladder 7 to the lifting lug at the front end of the hinged link movable platform 5, fixing it with a sealing pin 6, and sealing the other end of the boarding ladder 7 f. After the repair of the ship to be repaired 9 is completed, the dock crane 3 is used to lift and remove the boarding ladder 7 and the hinged movable platform 5, and place them on the top deck 2 of the dock wall, so as to complete the erection and dismantling of the boarding ladder of the outboard ship to be repaired. The method for erecting a boarding ladder after the outboard ship is docked at the floating dock of the present invention successfully solves the problem of interference between the walking of the dock crane and the boarding ladder during the repair of the outboard ship docked at the floating dock, avoids the frequent use of the dock crane to solve the interference problem of dismantling and reinstalling the boarding ladder, greatly improves the use efficiency of the dock crane and ensures the smoothness of the safety passage, thereby greatly improving the competitiveness.
