Problems solved by technology

[0005] First, after the completion of the section, the outer panel surface is below the section, it is inconvenient to mark the line, and the accuracy is not high
[0006] Second, after burning the kama on the outer plate, it needs to be cut off and polished to increase the workload. The efficiency of the chain hoist is not high, the positioning speed is slow, and the segmented fetal position takes a long time
[0007] Third, in the process of pulling the chain hoist hinge, the bilge keel sways back and forth, left and right, and there is an invisible safety hazard

Embodiment Construction

[0035] A construction method and device for sub-embedded installation of bilge keels of the present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments, in order to understand its structure type and usage more clearly. However, it cannot be used to limit the protection scope of the patent of the present invention.

[0036] Such as figure 1 , figure 2 and image 3 Shown, a kind of construction method for pre-embedded installation of bilge keel of ship section, this method comprises the following steps:

[0037] The first step is to draw the bilge keel pre-embedded tire frame process drawing according to the outer plate molding line, the original tire frame data and the bilge keel installation drawing, which includes the shape, height and position of the embedded tire frame, and the 5, the position and height of the flexible tire frame is a conventional tool in the prior art, and will not be repeated here. The ...

Abstract

The invention relates to a building method and device for ship block bilge keel embedding. The method includes the following steps that a bilge keel embedding jig frame flow chart is drawn; a form board is cut; a jig frame center line and an embedded jig frame installation positioning line are surveyed and marked; a movable jig frame is arranged; an embedded jig frame is arranged; and a bilge keel is installed. The invention further comprises a building device used for installing the bilge keel through ship block bilge keel embedding. The device comprises the embedded jig frame and the movable jig frame. By means of the building method for installing the bilge keel through ship block bilge keel embedding, the working efficiency can be effectively improved, and meanwhile the high safety performance is achieved.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a construction method and device for pre-embedded installation of bilge keels in sections of ships. Background technique [0002] At present, in ship construction, the segmented bilge keel is mainly installed by the following methods: [0003] After the large group of sections is completed, the outer panel surveys and draws the positioning line of the bilge keel, burns the keel at the edge of the section, passes the bilge keel through the chain hoist hinge, and hooks the chain hoist hook to the kama. After a long period of time, the construction personnel Pull the hinge, align it with the positioning line, and after several adjustments, pull the bilge keel to the position to be welded. [0004] This ship bilge keel construction method has the following deficiencies in the prior art: [0005] First, after the completion of the section, the outer panel surface is below the section, so...
