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 present invention relates to a method for drawing installation lines of inclined-plane groove-type compartments and an installation method for inclined-plane groove-type compartments. Type inspection line; S2. Knock out the sample punches of the two end points of the rib position line on the frame surface; S3. Install the grooved compartment on the frame surface of the inner longitudinal wall plate on the frame surface groove installation line, and then Turn the inner longitudinal wall plate over and place it on the tire frame, with the cargo tank facing up; S4, draw the rib line on the tank surface according to the end points of the rib line knocked out in S2; S5, draw the rib line on the cargo tank surface Draw the center line of the groove of the frame surface; S6, calculate the offset distance of the center line of the groove of the cargo tank surface relative to the center line of the groove of the frame surface according to the trigonometric function; S7, draw the installation line of the groove of the cargo tank surface, the Groove inspection line. The drawing method of the present invention solves the problem of difficult positioning on the slope, ensures that the installation positions of the grooved bulkheads on both 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...
