Abstract

The utility model relates to a buoyancy tank type raft boarding ladder, which is mainly used when a relatively large number of sailors need to board or leave a ship and comprises a gangway ladder. The buoyancy tank type raft boarding ladder is characterized in that the lower end of the gangway ladder is provided with a buoyancy tank (2) via a T shape stopper (19). The buoyancy tank is simultaneously dropped into water when the gangway ladder is placed into the water, and one end of the gangway ladder is supported by the buoyancy of the buoyancy tank to lead the gangway ladder to keep certain distance with the horizontal plane. When boarding or leaving the ship, sailors can board the buoyancy tank with a certain height with the horizontal plane, then board the ship via the gangway ladder; and the sailors can board the buoyancy tank via the gangway ladder, then take a ferry launch to leave the ship. The transition buoyancy tank is capable of reducing the risk that the sailors fall into water due to the level difference between the ferry launch and the gangway ladder caused by wave and ship shaking, thereby the buoyancy tank type raft boarding ladder increases safety of people boarding or leaving the ship.

Description

Floating box type is stepped on the raft ladder

(1) technical field

The utility model relates to a kind of floating box type and steps on the raft ladder.Be mainly used in and be used for more crewman and go on board or withdraw boats and ships.Belong to the Equipment of Vessel technical field.

(2) background technology

At present general boats and ships crewman goes on board or withdraws boats and ships and all adopt the gangway ladder that is installed on topside, gangway ladder transfer the back in traffic canoe interface because the influence that stormy waves and boats and ships rock, the comparison severity that pitches is brought great danger to crewman's safety.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of floating box type go on board or to withdraw safety of persons that can increase to step on the raft ladder.

The purpose of this utility model is achieved in that a kind of floating box type steps on the raft ladder, comprises gangway ladder, and the lower end of described gangway ladder is equipped with a buoyancy tank by T type hill holder.

The beneficial effects of the utility model are:

The utility model floating box type is stepped on the raft ladder, be that a buoyancy tank has been installed in the lower end of gangway ladder, gangway ladder puts down the back buoyancy tank and also puts into water simultaneously, the buoyant support of one head rest buoyancy tank of gangway ladder, gangway ladder and horizontal surface are maintained a certain distance, the people can climb up the buoyancy tank of keeping certain height with horizontal surface earlier when going on board or withdraw boats and ships, and then goes on board by gangway ladder.Can climb up buoyancy tank by gangway ladder when withdrawing boats and ships, go up crew boat then and withdraw.Because the middle transitional buoyancy tank has been arranged, reduce between crew boat and the gangway ladder because of wave and boats and ships rock the danger that the drop up and down that causes causes the crewman to fall into water, thereby, increased and gone on board or withdraw safety of persons.
