Problems solved by technology
[0003] The installation position of the trough-shaped compartment generally includes plane installation and inclined-plane installation. The operation and accuracy determination of the plane installation are relatively simple, but it is difficult to control the installation accuracy of the trough-shaped compartment on the inclined plane, which can easily cause large installation errors and require rework. Affect the quality and progress of ship construction

Embodiment Construction
[0029] The technical solution of the present invention is further described below in conjunction with specific embodiments:
[0030] The method of drawing the installation line of the inclined groove type compartment, such as figure 1 shown, including the following steps:
[0031] Step 1. Lay the inner longitudinal wall panels on the tire frame, with the frame surface 6 of the inner longitudinal wall panels facing upwards, draw the frame surface groove installation line 1, rib position line 2, and frame surface groove type inspection on the frame surface 6 Line 3, such as figure 2 and image 3 shown, including:
[0032] S8, first draw the rib position line 2 on the frame surface 6 according to the drawings;
[0033] S9. Determine the position of the groove centerline 5 of the frame surface: measure the distance from the edge of the inner longitudinal wall plate to the intersection point 4 of the groove centerline 5 of each frame surface and the intersection point 4 along ...

The invention relates to an inclined plane groove type bulkhead mounting line marking method and an inclined plane groove type bulkhead mounting method. The marking method comprises the following steps of S1, marking a framework surface groove type mounting line, a rib position line and a framework surface groove type inspection line on a framework surface; S2, respectively knocking out two end point sample punches of a rib position line on the framework surface; S3, a groove-shaped compartment being installed on a groove-shaped installation line of the framework surface on the framework surface of the inner longitudinal wall plate, then the inner longitudinal wall plate being turned over and then placed on a jig frame, and the surface of a liquid cargo tank facing upwards; S4, marking a rib position line on the liquid cargo tank surface according to the end point sample punch of the rib position line knocked out in the step S2; S5, marking a framework surface groove-shaped center lineon the liquid cargo tank surface; S6, according to the trigonometric function, the offset distance of the liquid cargo tank face groove profile center line relative to the framework face groove profile center line being calculated; and S7, marking out a liquid cargo tank surface groove-shaped mounting line and a liquid cargo tank surface groove-shaped inspection line. The scribing method solves aproblem that the positioning difficulty on the inclined plane is large, ensures that the mounting positions of the groove-shaped bulkheads on the two sides are consistent, and improves the construction quality.
Description
technical field [0001] The invention relates to the field of shipbuilding, in particular to a method for drawing lines for installing inclined-plane groove-shaped compartments and a method for installing inclined-plane groove-shaped compartments. Background technique [0002] In the process of modern ship construction, the trough compartment structure is more and more applied to the hull structure due to its advantages of light weight and good structural stability. In the process of segmented construction, the installation accuracy of the trough structure is extremely important, which directly affects whether the trough compartment is aligned with the trough structure in the segment during the subsequent hull structure loading process. In the process of segmented construction, accurately drawing out the installation line and inspection line of the trough structure can not only quickly and efficiently improve the efficiency and accuracy of structure installation, but also pro...
