Positioning and mounting method of ship side door

Abstract

The invention discloses a positioning and mounting method of a ship side door. The method comprises: installing a first angle square seat on an upper platform, installing a second angle square seat ona first gangplank, installing a first reflector plate on the first angle square seat, locating the original point of the first reflector plate and a connecting rod oil cylinder eye plate installationpoint on the same vertical line, and the original point of the second reflector plate coinciding with the circle center of a connecting rod installation eye plate; adjusting the position of the firstreflector plate up and down, and measuring the distance between the original point of the first reflector plate and the original point of the second reflector plate by using a total station, so thatthe measured distance is the sum of the lengths of the connecting rod oil cylinder, the first connecting rod and the second connecting rod when the connecting rod oil cylinder has the maximum stroke;and measuring the distance between the original point of the first reflector plate and the connecting rod oil cylinder eye plate mounting point, and calculating and machining the cutting allowance ofthe connecting rod oil cylinder. On the premise of ensuring the positioning precision of the connecting rod oil cylinder eye plate, the operation intensity is reduced, and the related tool cost is saved, so that the installation period of a channel system is shortened, and the construction quality is ensured.

Description

technical field [0001] The invention belongs to the technical field of ship building, and in particular relates to a method for positioning and installing a side door of a ship. Background technique [0002] The ship's side door is used for the entry and exit of vehicles, and is the key to the entire channel system. When the side door is opened, it can facilitate the entry and exit of vehicles. When the side door is closed, it effectively separates the outside of the hull and the vehicle garage, and plays the role of a watertight bulkhead. The traditional side door structure adopts an integrated structure. When the side door is closed, it adopts front sealing and pressing, that is, when the door panel is lifted and closed, the sealing strip is pressed when the door panel is lifted and closed. The sealing pressure is closely related to the pressing force, and the weight of the side door Large, it is difficult to ensure sufficient pressing force, and the sealing performance o...

The traditional side door structure adopts an integrated structure. When the side door is closed, it adopts front sealing and pressing, that is, when the door panel is lifted and closed, the sealing strip is pressed when the door panel is lifted and closed. The sealing pressure is closely related to the pressing force, and the weight of the side door Large, it is difficult to ensure sufficient pressing force, and the sealing performance of the side door cannot be guaranteed
