Technical Field

The utility model relates to the technical field of ship accessories, in particular to a ship gangway.

Background Art

A ship is a man-made means of transportation that mainly operates in geographical waters. In addition, civilian ships are generally called ships, military ships are called warships, and small ships are called boats or boats, which are collectively called ships or boats. The interior mainly includes accommodating space, supporting structure and drainage structure, and has a propulsion system that utilizes external or self-contained energy. The gangway is the most unique equipment on the ship. It is a bridge built between the ship and the dock. It plays the role of transporting goods or providing relevant personnel to board and disembark. Most of the gangways are set at the stern, and some are set at the bow and the side of the ship. Existing gangways usually cannot control the length, which makes the driver's docking technology requirements very high. At the same time, the side protection of the gangway is very limited and the protection is low.

By adopting the above technical solution, when the ship docks, the flipping mechanism drives the gangway body to rotate relative to the main board of the hull and lowers the gangway body. When it is found that there is a gap between the end of the gangway body and the shore end, the adjusting motor is started to drive the gear to rotate. The rotation of the gear drives the rack to move forward, thereby driving the extended gangway to slide out from the sliding cavity in the gangway body. During this period, the slide plate slides relative to the slide groove to limit the sliding of the extended gangway, and the overall length of the gangway is adjusted, so that the end of the gangway is easier to dock and the docking efficiency is improved; the first protective rod, the second protective rod and the first cross bar and the second cross bar jointly protect both sides of the gangway.
