Side port

Abstract

The invention discloses a side port. The side port comprises a door frame and a cabin door, wherein the top end of the cabin door is rotationally connected to the top of the door frame through an end hinge device; the end hinge device comprises a fixed seat, a first connection arm extending upwards from the fixed seat, a second connection arm horizontally bent from the tail end of the first connection arm, and a third connection arm vertically bent downwards from the tail end of the second connection arm; the fixed seat is detachably installed on the surface of the inner wall of the cabin door through screws; the tail end of the third connection arm is rotationally connected to the door frame; the inner side of the second connection arm is sunken upwards to form a clamping groove; the door frame is provided with a locking device in a manner of being corresponding to the end hinge device; and the clamping groove comprises a drive device, and locking blocks connected to the two sides of the drive device. In the side port disclosed by the invention, after the cabin door is closed, the drive device drives the two locking blocks to move to the two sides and be inserted in the corresponding clamping grooves simultaneously, and then abnormal opening for the cabin door is limited; and before the cabin door is opened, the drive device drives the two locking blocks to retract, and the limit on the end hinge device is cancelled.

Description

technical field [0001] The application belongs to the technical field of ships, and in particular relates to a side door. Background technique [0002] The side door of a large ro-ro ship is an important channel for cargo to go on and off the ship. The side door not only plays the role of opening and closing, but also serves as a passage for driving when opened. The upper end of the side door is generally hoisted by steel cables, and the lower end is hinged. When opening, the upper end of the side door is lowered. Side-lapped on the pier for loading and unloading cargo. Large ships face complex weather conditions during sea voyages. When the side doors are closed, they need to have certain sealing performance to prevent water ingress. The traditional side door is sealed by setting a ring of sealing strips on the door frame, and sealing by pressing the sealing strips when the door panel is lifted and closed. This structure adopts front compression sealing, and the sealing pe...

AI Technical Summary

Problems solved by technology

The traditional side door is sealed by setting a ring of sealing strips on the door frame, and sealing by pressing the sealing strips when the door panel is lifted and closed. This structure adopts front compression sealing, and the sealing performance is closely related to the compression force. It is difficult to ensure sufficient pressing force for sealing during hoisting, and the sealing performance cannot be guaranteed
