Skid-proof platform gangway ladder

Abstract

The invention discloses a skid-proof platform gangway ladder, comprising two parallel front step stanchions and two parallel rear step stanchions; a plurality of pedals arranged in parallel are movably mounted on the front step stanchions and the rear step stanchions; as for the gangway ladder, the upper ends of the front step stanchions and the rear step stanchions are movably connected on the edge of a platform deck; the pedals on the front step stanchions and the rear step stanchions, the front step stanchions and the rear step stanchions are configured into a parallelogram with exchangeable included angles; a base plate is connected behind the two rear step stanchions; the upper end of the two front step stanchions and the edge of the platform deck are provided with guardrails; and one side of the front step stanchions is connected with a lifting bracket. According to the invention, when the ships are close to unmanned oil platform on the sea, no matter any angle the step stanchions are located, when the gangway ladder is lifted, the adjacent pedals, and the front and the rear step stanchions are configured into the parallelogram with exchangeable included angles, so as to ensure that the pedestals are always level and avoid the gangway ladder workers from the feel of uneven road, the walk is more comfortable and steady, the safety in transporting goods is enhanced, and the potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to a gangway, in particular to an anti-slip platform gangway used on an offshore unmanned oil and gas platform. It belongs to the field of offshore oil engineering. Background technique [0002] At present, in offshore oil operations, offshore unmanned oil and gas production platforms usually use gangway. [0003] The gangway includes: two parallel ladder columns, on which several pedals arranged in parallel are installed by welding or bolts, and the ladder columns and the pedals form a whole, and the angle of the pedals is fixed. One end of the ladder column is connected to the side of the platform with a fixed pivot pin, and the other end of the ladder column is lifted or lowered by the wire rope of the electric winch to facilitate the shuttle between the platform and the ship. Due to the large tidal range at sea, taking the Bohai Sea as an example, its average wave height is 1 meter, with a difference of 5 meters up and down....

AI Technical Summary

Problems solved by technology

Due to the large tidal range at sea, taking the Bohai Sea as an example, its average wave height is 1 meter, with a difference of 5 meters up and down. With the horizontal position of the ladder columns at different angles, the pedals are also at different angles. Therefore, the pedals It cannot be used at a horizontal angle most of the time; and due to the humidity at sea, the pedals of the gangway are often slippery, which makes it easy for people to slip and fall, especially when people are carrying items and cannot hold the railing with both hands It is very dangerous and brings potential safety hazards to production safety.
