Folding turnover type boarding ladder

Abstract

The invention discloses a folding turnover type boarding ladder which comprises a turnover platform and a folding ladder, supporting shafts are arranged on the two side faces of the turnover platform, the turnover platform is installed on a ship body through bearing seats, a first driving cylinder is arranged between the turnover platform and the ship body, so that the turnover platform can rotate relative to the horizontal plane, a mounting frame is arranged on the turnover platform, a turnover plate is arranged on the mounting frame, the folding ladder is rotationally arranged on the turnover plate, and a second driving cylinder is arranged between the folding ladder and the turnover plate, so that the folding ladder can rotate relative to the turnover plate. According to the folding turnover type boarding ladder, the accommodation ladder is designed to be of a structure capable of being folded and overturned to be stored, the occupied space is small, the damage risk is reduced, after the ladder is completely unfolded, the ladder can turn in the horizontal plane and swing up and down in the vertical plane, various use conditions are met, personnel can conveniently boarding, and the folding turnover type boarding ladder is suitable for being integrated on various ship bodies.

Description

technical field [0001] The invention relates to the technical field of boarding ladders, in particular to a foldable and reversible boarding ladder. Background technique [0002] No matter civilian ships or warships, they need to be equipped with gangway, so that when the ship is docked at the dock, it is convenient to get on and off the ship. At present, most ships are equipped with a fixed-length boarding ladder on the side of the ship. The ladder is lowered by the crew's movement and the cooperation of the hydraulic winch. The automation of retracting the ladder is low, and there are unsafe factors, and this kind of gangway Generally, it can only be retracted close to the side of the ship. After the personnel board the ship, the ladder is put away and placed in the passage not closed by the outer plate on the side of the ship, which takes up a large passage space. In addition, the fixed gangway is placed on the deck, which is easily corroded by seawater and rainwater, an...

Problems solved by technology

At present, most ships are equipped with a fixed-length boarding ladder on the side of the ship. The ladder is lowered by the crew's movement and the cooperation of the hydraulic winch. The automation of retracting the ladder is low, and there are unsafe factors, and this kind of gangway Generally, it can only be retracted close to the side of the ship. After the personnel board the ship, the ladder is put away and placed in the channel not closed by the outer plate on the side of the ship, which takes up a large channel space.

In addition, the fixed gangway is placed on the deck, which is easily corroded by seawater and rainwater, and has a low service life, and the fixed gangway cannot be used as a platform channel to connect with another ship or platform, which is inconvenient for personnel to come and go, and its functions are limited
