Problems solved by technology

In the past, the side push bell mouth coamings and deflectors were assembled in bulk at the berth stage, which made it difficult to guarantee the overall line shape, and the installation accuracy was low, requiring repeated adjustments. The berth took too long and affected the ship production cycle

Abstract

The invention relates to a manufacturing method of a side push bell mouth panel and a deflector, comprising the following steps: selecting a base surface of a tire frame; Projecting the contour linesof the side pushing bell mouth enclosure plate and the air guide plate on the hull outer plate onto the base surface of the jig frame; setting a first upright column group and a second upright columngroup; welding a jig template on the upper ends of the first column group and the second column group respectively to complete the jig manufacturing; Lifting a plurality of processed and molded shroudboards to the tire frame respectively and fixing the plurality of shroud boards and the tire frame template respectively; splicing and fixing the side push bell mouth shroud and the air guide plate;the side push bell mouth shroud plate and the air guide plate are separated from the tire frame template respectively and the integral structure after the side push bell mouth shroud plate and the airguide plate are spliced and molded is obtained. The invention provides a manufacturing method of a side pushing bell mouth shroud and a deflector, which can save time for bulk loading of a ship slip,improve the working efficiency of the ship slip, and ensure the accuracy of the bell mouth shroud and the deflector.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a method for making a side-throwing bell mouth coaming and a deflector. Background technique [0002] The side thruster is actually a kind of propeller propeller, which is generally used as a lateral auxiliary propulsion device of the ship, which can make the ship move laterally or turn on the spot, and improve the maneuverability of the ship. According to the position of the side thruster, it can be divided into bow side thruster and stern side thruster. The axial direction of the side thruster is perpendicular to the midship section of the ship. deflector. [0003] Because the bell mouth coaming connects the side thruster cylinder and the outer plate of the hull, and at the same time transitions smoothly with the deflector, the curvature of the line changes greatly and requires high precision. In the past, the side thrust bell mouth coamings and deflectors were assembled in bulk a...
