Wave compensation gangway ladder independently controlled by variable-amplitude oil cylinder

Abstract

The invention discloses a wave compensation gangway ladder independently controlled by a variable-amplitude oil cylinder, and belongs to the technical field of gangway ladders, the gangway ladder comprises a base, a revolving platform, a support frame and a gangway ladder, the revolving platform is mounted on the base, the support frame is fixed on the revolving platform, and the support frame is connected with the tail end of the gangway ladder through a first knuckle bearing. The rotary platform and the accommodation ladder are connected through a variable-amplitude oil cylinder, the pitching angle of the accommodation ladder is changed through the variable-amplitude oil cylinder, and the left-right inclination angle of a bottom ladder of the accommodation ladder can be adjusted. The left-right inclination angle and the pitching angle of the gangway ladder can be controlled through the two independently-controlled variable-amplitude oil cylinders and the multiple knuckle bearings, equipment and cost are not additionally increased, the wave compensation function of the left-right inclination angle of the gangway ladder is achieved, and the wave compensation function of the left-right inclination angle of the gangway ladder is achieved in cooperation with the adjustability of the up-down pitching angle of the gangway ladder and the adjustability of the pitching angle of a landing ladder. And the whole gangway ladder can rotate under the driving of the rotary platform, so that the gangway ladder is suitable for being used in a complex marine environment, and the comfort and safety of people using the gangway ladder are improved.

Description

technical field [0001] The invention belongs to the technical field of gangway, in particular to a wave compensation gangway independently controlled by luffing oil cylinders. Background technique [0002] The gangway is widely used in environments such as offshore platforms, ships or ports. Under the existing technical conditions, the gangway usually touches the platform or deck to be landed by changing the pitch angle. However, due to the complexity of the offshore environment, the platform or ship will Follow the waves to generate shaking, and the up and down shaking can be compensated by changing the pitch angle or the height of the landing ladder, but it is difficult to compensate the inclination angle in the left and right directions. The board will swing and tilt following the waves. Although the amplitude of the swing or the angle of inclination is not very large, it still has a certain impact on the comfort and safety of the gangway, and also has an impact on the li...
