Problems solved by technology

Although the steps of the boarding ladder fixed on the platform can be adjusted according to the angle of the boarding ladder, during offshore construction, the relative movement of the offshore construction platform and the traffic boat is relatively frequent and the instantaneous relative motion is relatively large. Ships, such dock boarding ladders are unreliable and unsafe

Abstract

The invention discloses a self-elevating boarding ladder, comprising a main ladder, a tail ladder and a tower. The tail ladder is connected with the main ladder. One end of the main ladder is fixed onthe tower through a pin shaft assembly, and the other end of the main ladder is connected with an electric motor fixed on a platform through a pulley assembly. A spring push rod is arranged on the tower. The joint portion of the spring push rod is connected with the main ladder in a contact way. A locking device is arranged below the spring push rod. The locking device is fixed on the tower. Theboarding ladder can be retracted, does not occupy the crane of an offshore wind power self-elevating operating platform, and can reach own balance with the instantaneous movement of a traffic boat. Asa passageway between the platform and the traffic boat, the boarding ladder can rotate with the instantaneous movement of the traffic boat caused by the ebb and flow of the sea level and waves. The self-elevating boarding ladder occupies a small platform space, has high reliability and high safety and is convenient to install. The self-elevating boarding ladder can effectively improve the efficiency of offshore wind power construction.

Description

technical field [0001] The invention relates to a self-elevating boarding ladder, which belongs to the technical field of ships. Background technique [0002] At present, in the process of offshore wind power construction, people go up and down the platform through the hanging cage, and when using the hanging cage, they need to rely on the precious resource of the crane, which affects the efficiency of offshore construction. Therefore, it is necessary to study a method that can realize personnel without using the crane Equipment for getting on and off the offshore wind power jack-up platform. [0003] At present, the boarding ladder is mainly used for personnel to get on and off the ship in the shipyard, and when the ship is docked, people get on and off the ship. The structure of the boarding ladder for the wharf is that one end is fixed on the wharf, and the other end is lapped on the ship. Since the sea level in the wharf area is relatively calm, the ship will not move i...
