Telescopic pilot gangway ladder

Abstract

The invention discloses a telescopic pilot gangway ladder. The telescopic pilot gangway ladder comprises an upper platform arranged on a side deck, a transmission shaft, a hanging bracket, an upper ladder and a lower ladder. The top end of the upper ladder is hinged to the upper platform, and the lower ladder axially sleeves the upper ladder to form the telescopic gangway ladder. The hanging bracket forms a fixed-axis swinging mechanism through using a sling to pull pulleys arranged at two sides of the bottom end of the upper ladder, wherein the lower ladder swings along with the upper ladder. A hauling mechanism is arranged at the outer wall of the upper end of the upper ladder, chain wheels are arranged at two ends of each of the outer walls of two sides of the upper ladder, and a chain connected between the hauling mechanism and the lower ladder is driven through the chain wheels to haul the lower ladder to axially and telescopically regulate relative to the upper ladder. Through using power to haul the lower ladder to axially and telescopically move relative to the upper ladder and swinging the fixed-axis swinging mechanism, the gangway ladder is easy and convenient to operate, capable of stretching freely and capable of quickly and precisely arriving at a preset position to facilitate a pilot to redirect to go on board at the nearest position.

Description

technical field [0001] The invention relates to a marine auxiliary machine, in particular to a gangway, especially a retractable pilot gangway. Background technique [0002] When large and medium-sized ships enter the port, they need to obey the guidance of the pilot at the port in order to achieve safe docking at the target wharf. The hull of large and medium-sized ships is very large, and the deck is relatively high from the water surface. Pilots boarding the ship need to rely on the soft ladder or the gangway provided by the ship. The soft ladder is a simple structure and convenient way for the pilot to board the ship. Because it is laborious and difficult for the pilot to climb the soft ladder, and the safety is poor, the soft ladder is not the best way for the pilot to board the ship. Launching the gangway is the most labor-saving way for the pilot to board the ship. However, the position of the gangway equipped with the ship is fixed, and the deployment position does ...

AI Technical Summary

Problems solved by technology

Due to the different equipment on the deck of ships for different purposes, there are not many matching points between the soft ladder and the gangway installed at the fixed point on the ship's side. In addition, the adjustability of the hanging chain type telescopic gangway and the cable pull type telescopic gangway in the prior art is not strong. It can only cooperate with the soft ladder in a limited position at a fixed position and a fixed angle

The gangway with this defect cannot meet the needs of the ship to allow the pilot to board the ship smoothly under different draft conditions
