[0057] Refer to the following Figures 1 to 18 To describe a method for installing a ship cockpit window frame of the present invention. In the description of this embodiment, the reference terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0058] like Figure 1-Figure 18 As shown, an embodiment of the present invention provides a method for installing a ship cockpit window frame 3, comprising:

[0059] Step S1, lofting the cockpit bow cladding plate 2 and the corresponding window frame 3.

[0060] Optionally, the cockpit bow cladding plate 2 and the corresponding window frame 3 are lofted by CAD proportional lofting, and the dimensions of each component of the bow cladding plate 2 and the window frame 3 can be directly obtained through CAD measurement. Preferably, 1:1 lofting is selected.

[0061] In order to facilitate the description of the bow cladding plate 2 and the window frame 3, the bow cladding plate 2 and the corresponding window frame 3 are now divided into multiple sections. Optionally, the sections can be divided according to the corresponding rib position number and part number of the bow cladding plate 2. Specifically, refer to Figure 1 The bow wall plate 2 can be divided into FR68C (including FR68A-A1 and FR68B-A1), FR65C (including FR65A-A1 and FR65B-A1), FR65T (including FR65Q-A1 and FR65R-A1), LB4B (including LB4B-A1), LB4C (including LB4C-A1), LB4Q (including LB4Q-A1) and LB4R (including LB4R-A1).

[0062] Step S2, according to the lofting result, obtain the shape and size drawings of the plate materials of each section of the bow cladding plate 2 and the profile 31 of the window frame 3.

[0063] Furthermore, the shape and size drawings of the plates of each section of the bow cladding plate 2 are obtained, including:

[0064] Draw the center line of the bow cladding plate 2.

[0065] Move the bow cladding plate 2 to the center line and determine the position of the intersection point on the outer frame of the bow cladding plate 2.

[0066] Furthermore, the bow cladding plate 2 is brought to the center line, and the position of the intersection point on the outer frame of the bow cladding plate 2 is determined, including:

[0067] Move the center line in the vertical direction to determine the four intersection points of the center line and the frame of the bow cladding plate 2.

[0068] Obtain the distances from the four intersection points to the intersection points of each edge line of the bow cladding plate 2 frame.

[0069] Connect the four intersection points in pairs and extend the connecting line of the intersection points to the center line to determine the positions of the four intersection points on the center line.

[0070] From the four intersection points, draw lines in a horizontal direction perpendicular to the center line to both sides, and the length of the lines is equal to the distance from the four intersection points to the intersection points of the edges of the frame of the bow cladding plate 2. The two end points of the lines are the intersection points of the edges of the frame of the bow cladding plate 2.

[0071] At the intersection of the center line and the frame of the bow cladding plate 2 close to the compass deck 1, lines are drawn to both sides in the horizontal direction perpendicular to the center line. The obtained intersection point of the edge lines of the frame of the bow cladding plate 2 is the projection point of the actual intersection point of the edge lines of the frame of the bow cladding plate 2 on the beam arch 11 of the compass deck 1.

[0072] Specifically, take the bow cladding plate FR68C as an example. Figure 1-Figure 3 ,from Figure 2 The distances between aj, ab and bg on the bow cladding plate 2 are obtained from the following. The center line of the bow cladding plate FR68C is first drawn below, and the distances between aj, ab and bg are respectively transferred to the center line, so that the positions of the four intersection points a, j, b and g on the center line can be obtained, that is, Figure 1 The actual positions of the four intersections a, j, b, and g in the center line. Then draw lines from the four intersections a, j, b, and g to both sides in the horizontal direction perpendicular to the center line. The length of the line is Figure 1 The distances of ad=af, jk=jl, bc=be, hg=gi obtained in the above equation can be used to obtain the positions of the intersection points of d, f, k, l, c, e, h, and i. Figure 3 Wherein, d and f are the projection points of the intersection points of the borders of the actual bow cladding plate 2 on the beam arch 11 of the compass deck 1.

[0073] Determine the position of the intersection of the actual side lines of the bow cladding plate 2 frame. Figure 3 and Figure 4 , determine the position of the intersection point of the actual bow cladding plate 2 frame, including:

[0074] The half width and height of the beam arch 11 can be determined by lofting measurement. Optionally, the half width of the beam arch 11 is 15405 mm, and the height of the beam arch 11 is 225 mm.

[0075] According to the intersection of the frame of the bow cladding plate 2 close to the compass deck 1, the length of the line drawn to both sides along the horizontal direction perpendicular to the center line can be calculated to obtain the distance from the intersection of the edge line of the frame of the bow cladding plate 2 to the projection point on the beam arch 11 of the compass deck 1. Specifically, the spacing dd1 can be calculated according to the right triangle law. Among them, d1 is the projection point.

[0076] After determining the intersection of the border lines of the bow cladding plate 2 frame, draw a line perpendicular to the beam arch 11 of the compass deck 1, and the distance of the line is the distance from the actual intersection of the border lines of the bow cladding plate 2 frame to the projection point on the beam arch 11 of the compass deck 1, that is, the distance dd1. Thus, the position of the actual intersection of the border lines d1 of the bow cladding plate 2 frame can be obtained. Similarly, the position of another actual intersection of the border lines f1 of the bow cladding plate 2 frame can be obtained.

[0077] After determining the positions of the actual intersections of the side lines of the frame of the bow wainscot plate 2, the positions of the intersections on the outer frame of the bow wainscot plate 2 can be determined in combination with the intersections of the side lines of the frame of the bow wainscot plate 2. Connect the intersections and then connect the intersections to obtain the shape and size drawings of the outer frame of the bow wainscot plate 2. Draw the internal profile 4, the side line of the compass deck 1, and the lower mouth compensation amount 5 on the outer frame shape and size drawings, and mark the corresponding information to obtain the shape and size drawings of the plate material of the bow wainscot plate 2. Specifically, connect the intersections d1, f1, k, l, c, e, h and i, draw the internal profile 4, the side line of the compass deck 1, and the lower mouth compensation amount 5, and mark the corresponding information to obtain the following. Figure 3 The shape and size drawing of the plate material of the bow cladding plate 2 is shown. Optionally, the lower opening compensation amount 5 is 9 mm.

[0078] The method of obtaining the shape and size drawings of the other segmented bow cladding panels 2 is similar to the principle of the bow cladding panel FR68C. Figure 5-Figure 6 .

[0079] Furthermore, the shape and size drawings of the profile 31 of each section of the window frame 3 are obtained, including:

[0080] The initial specifications of the profiles 31 constituting the window frame 3 are determined.

[0081] According to the angle between two adjacent sections of bow cladding plates 2, the connection angle between adjacent window frames 3 is determined;

[0082] According to the connection angle, the joint surface of each profile 31 is cut to obtain the shape and size drawings of the profile 31 of each section of the window frame 3.

[0083] Specifically, take the window frame 3 corresponding to the bow wall plate FR68C as an example. Figure 3 The k, j, l, e, b, and c in the figure can be used to obtain the approximate shape and size of the window frame 3, such as Figure 7 Reference Figure 1 , it is known from the measurement that the connection angle between the two adjacent sections of the bow cladding 2 and the window frame 3 is 133°. Then the two ends of the parts FR68C-E1 and E2 are cut into shapes with the upper top surface angles of 66.5° and 113° respectively. And the parts FR68C-E5 and E6 are cut according to Figure 8 The right and left halves of the window frame 3 splicing diagram at o and p are cut at an inclined angle. The outer angle of the two splicing diagrams after splicing is also 133°.

[0084] Optionally, one can make Fig. 9 The wooden template shown has angles of 66.5° and 113°. Use the wooden template 6 to mark the allowance lines on the parts FR68C-E1 and E2 to cut the allowance.

[0085] The method of obtaining the shape and size drawings of the profiles 31 of the other segmented window frames 3 is similar to the principle of the window frames 3 corresponding to the bow cladding FR68C. Figure 10-13 shown.

[0086] Step S3 , manufacturing the plate materials of each section of the bow cladding plate 2 and the profile materials 31 of the window frame 3 according to the shape and size drawings of the plate materials of each section of the bow cladding plate 2 and the profile materials 31 of the window frame 3 .

[0087] By laying out the shape and size drawings of the plate material of the bow cladding plate 2 and the profile material 31 of the window frame 3, and making the relevant plate material and profile material 31 according to the drawings, it is more accurate than measuring with a tape measure.

[0088] Further, refer to Fig.14 , assembling the finished profiles 31 of the window frame 3 to form a complete window frame 3, including:

[0089] According to the shape and size of the window frame 3 , a positioning reference line of the window frame 3 is marked on the welding platform 7 .

[0090] According to the positioning reference line, the profile 31 of the window frame 3 is fixed on the welding platform 7 for butt welding. Among them, a plurality of insertion holes 71 are evenly opened on the welding platform 7, and the profile 31 of the window frame 3 is fixed by the elbow fixture 8 inserted in the insertion holes 71. In addition, before the profile 31 of the window frame 3 is fixed on the welding platform 7 for butt welding, the operator uses a steel tape measure to check the diagonal angle, spacing and flatness of the window frame 3, and welds after meeting the requirements.

[0091] By marking the positioning reference line in advance and splicing according to the positioning reference line, the splicing accuracy of the window frame 3 is higher. At the same time, the elbow tool 8 is matched with the socket 71 to fix the profile 31, which can effectively avoid bending deformation caused by welding.

[0092] Step S4, reference Figure 15-17 According to the inclination angle of each section of the bow cladding plate 2, a tire frame 9 is made, and the bow cladding plate 2 and the complete window frame 3 are placed on the corresponding tire frame 9 for welding to form the installation of a small group of independent cockpit window frames 3. By setting the tire frame 9, it is convenient to control the inclination of the bow cladding plate 2 and the window frame 3, which helps to improve the assembly accuracy of the bow cladding plate 2 and the window frame 3.

[0093] Furthermore, the bow cladding plate 2 includes a vertical plate and an inclined plate. When the bow cladding plate 2 and the complete window frame 3 are placed on the corresponding tire frame 9 for welding, the inclined plate is placed horizontally on the tire frame 9, and the vertical plate is placed obliquely on the tire frame 9. By arranging the inclined plate horizontally, the welding of the window frame 3 and the bow cladding plate 2 is facilitated.

[0094] Step S5, butt-weld multiple sections of the bow bulkhead plate 2 and the window frame 3 to complete the installation of the large-assembled cockpit window frame 3. Refer to Fig.18 .

[0095] In summary, by precisely lofting the bow bulkhead plate 2 of the cockpit and the corresponding window frame 3, the shape and size drawings of the sheet material of the bow bulkhead plate 2 and the profile 31 of the window frame 3 are obtained. And the sheet material of the bow bulkhead plate 2 and the profile 31 of the window frame 3 are fabricated according to the drawings, making the fabricated parts have higher precision. The jig 9 is fabricated according to the inclination angle of the bow bulkhead plate 2, and the butt joint installation of the bow bulkhead plate 2 and the window frame 3 is carried out on the jig 9, which is convenient for controlling the inclination of the bow bulkhead plate 2 and the window frame 3, thereby improving the assembly precision of the bow bulkhead plate 2 and the window frame 3. In addition, the positioning reference line is surveyed and marked in advance on the welding platform 7, and the profile 31 of the window frame 3 is hoisted and spliced according to the positioning reference line, which can ensure the accuracy of the splicing of the window frame 3. Furthermore, the glass installation size and flatness after the butt joint of the large-assembled cockpit bow bulkhead plate 2 and the window frame 3 will be more accurate.

[0096] The above embodiments are only illustrative of the principles and effects of the present invention, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention.
