Wave-adaptive full-automatic accommodation ladder device for ocean platform and application method thereof

Abstract

The invention discloses a wave self-adaptive ocean platform full-automatic gangway ladder device and an application method thereof.The wave self-adaptive ocean platform full-automatic gangway ladder device comprises a fixed ladder, an extension ladder, a driving system, a laser ranging system and a safety device, the extension ladder is arranged in the space between the fixed ladder and a ship board outer plate, the driving system is located on an ocean platform deck, and a noose wound on a winch is connected with the extension ladder; the laser ranging system is located at the bottom of the extension ladder, one end of the safety and protection device is connected with a deck of the ocean platform, the other end of the safety and protection device is connected with the extension ladder, and after a ship travels to one side of the ocean platform and is detected by the laser ranging system, the PLC control system controls the extension ladder to ascend and descend along with fluctuation of the ship according to the preset height. The height of the operator stepping on the folding pedal is always kept unchanged, and the operator is connected with the safety and protection device when climbing. The device has the advantages of being simple in structure, safe, reliable, low in cost and easy and convenient to operate, avoiding collision between the gangway ladder and a ship and collision between an operator and the ship, and avoiding falling of the operator in a quick state.

Description

technical field [0001] The invention belongs to the technical field of ocean platforms, and relates to a fully automatic gangway device for ocean platforms adaptive to waves and an application method thereof. Background technique [0002] During the offshore construction of the marine jack-up platform, the main deck of the platform hull is usually more than 10 meters away from the water surface, and the platform takes a long time to lift piles each time. During the operation, operators often need to go up and down the platform. Due to the large distance between the main deck of the platform and the water surface, and the strong wind and waves at sea, it is very inconvenient for people to get on and off the platform. Especially in the weather of strong wind and waves, there is a need for a simple, fast and less affected platform device for going up and down by wind and waves. There are two traditional methods. One is to use a crane on the platform to lift personnel. In this ...
