Accommodation ladder for wind power platform and accommodation ship

Abstract

The invention relates to an accommodation ladder for a wind power platform and an accommodation ship. The accommodation ladder comprises a rotary base welded on the boardside of a ship body and connected with a rotary bearing, wherein the rotary bearing is connected with a tower and driven by a hydraulic motor, the root part of the tower is connected with a main ladder through hinge pins, a main ladder pulley set is arranged in the middle of the main ladder and on the tower and is controlled by a main winch, a spring push rod mechanism is arranged at the top of the tower, a telescopic auxiliary ladder is inserted into the main ladder, a main-auxiliary ladder winch is mounted at the top of the main ladder, the top of the auxiliary ladder is connected with a tail ladder through two hinge pins, a tail ladder pulley is arranged at the tail of the tail ladder, and a reset locking device is arranged between the tower and the main ladder. Compared with a crane, the accommodation ladder is low in cost and has high safety, the technical requirements for operators are low, the time is short, the accommodation ladder is high in automation with the adoption of mechanical and electrical integrated automation, the inclination angle of the main ladder can be flexibly adjusted, collection and release of the ladder can be started or stopped through one key, the accommodation ladder is not affected by waves of the accommodation ship, and accordingly, people can stably go up and down the platform.

Description

technical field [0001] The invention relates to the field of electromechanical integrated hoisting equipment, in particular to a gangway used for wind power platforms and transportation ships. Background technique [0002] At present, the leg-type wind power platform lifts the platform through the legs to make the platform out of the water and achieve a stable and static effect. The traffic ship cannot directly lean against the side of the platform, so the connecting bridge between the wind power platform and the traffic ship is generally a crane. [0003] The shortcomings of platform cranes for transporting personnel and light-loaded materials on and off the ship are: when large-scale cranes hoist personnel and light-loaded materials on and off the ship, they are severely affected by wave currents and wind loads, and the cage and personnel are relatively light and will rotate in strong winds Indefinitely, when falling into the traffic boat, due to the wave flow, the traffic...

Problems solved by technology

[0003] The shortcomings of platform cranes for transporting personnel and light-loaded materials on and off the ship are: when large-scale cranes hoist personnel and light-loaded materials on and off the ship, they are severely affected by wave currents and wind loads, and the cage and personnel are relatively light and will rotate in strong winds Uncertain, when falling into the traffic boat, due to the wave flow, the traffic boat swings up and down relatively large, making it very dangerous for people to go up and down

[0004] The crane transports people up and down, not only the cost is high, but also the hoisting requirements are very high
