Dock boarding ladder

Abstract

The invention discloses a dock boarding ladder. The boarding ladder comprises a guiding plate, a long ladder and a derrick ladder, the lower end of the long ladder is slidably connected with the guiding plate, the upper end of the long ladder is hinged to the bottom of the derrick ladder, and fixing parts connected with grooves and tongues in the ship side in a hung mode are further arranged on the outer walls of the derrick ladder. The dock boarding ladder is simple in structure and convenient to use and can adapt to different ship heights, the derrick ladder of the boarding ladder is hung onthe ship side, the derrick ladder is hinged to the long ladder, the lower end of the long ladder is connected with the guiding plate through a sliding structure, when the height of a ship is changed,the lower end of the long ladder slides on the guiding plate, thus an included angle between the long ladder and the derrick ladder is automatically adjusted to the optimal position and does not needto be adjusted all the time by a worker, the flexibility of the boarding ladder is improved, and the adaptability of the boarding ladder is expanded.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to a wharf boarding ladder. Background technique [0002] When the ship is docked at the wharf for repair or maintenance, construction personnel need to provide a special wharf boarding ladder passage for getting on and off the ship. The current wharf boarding ladder generally stands directly on the wharf with the ladder ladder, and the boarding ladder of the wharf The platform is at the top, and the ladder is fixed by welding fixtures on the deck of the ship, which makes it necessary to cut the welded part every time the ship leaves the dock, which brings a lot of grinding, painting workload, docking It is time-consuming, laborious and wasteful to re-weld again. In addition, due to the different depths of various ships, the height of the boarding platform of the ladder is fixed, and the deck of the ship will be higher or lower than the boarding platform. At this time, it is...

[0002] When the ship is docked at the wharf for repair or maintenance, construction personnel need to provide a special wharf boarding ladder passage for getting on and off the ship. The current wharf boarding ladder generally stands directly on the wharf with the ladder ladder, and the boarding ladder of the wharf The platform is at the top, and the ladder is fixed by welding fixtures on the deck of the ship, which makes it necessary to cut the welded part every time the ship leaves the dock, which brings a lot of grinding, painting workload, docking It is time-consuming, labor-intensive, and expensive to re-weld

In addition, due to the different depths of various ships, the height of the boarding platform of the ladder is fixed, and the deck of the ship will be higher or lower than the boarding platform. At this time, it is necessary to cut or modify one side of the ship's side on site. railings to match the height of the boarding platform; or replace the boarding ladders of other platforms with different heights, that is to say, multiple boarding ladders must be equipped to adapt to different ships, which increases the cost and occupies space

At the same time, due to the long docking time of the ship, with the influence of the ebb and flow, the height difference between the deck and the boarding ladder of the same ship will also produce different height differences in different time periods. If different heights are configured for the same ship The boarding ladder will take up more dock space
