Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and specifically, to a manufacturing method of an anchor platform sample box. Background Art

[0002] Anchoring, also known as dropping the anchor and mooring, is a mooring method for ships. Usually, a bow navigation anchoring device is set on the ship, which is used for the ship to temporarily moor when waiting for a berth or tide in an anchorage, in the port or in a sheltered water area. Usually, the anchor chain diameter and the weight of the anchor are determined according to the calculation result of the outfitting number specified by the classification society. The bow anchor devices set on a transport ship are generally symmetrically arranged on the port and starboard sides. The anchor and the anchor chain are thrown into the water through the hawsepipe. The hawsepipe passes through the bow structure. The included angle between the axis of the hawsepipe and the vertical line is generally 30° - 60°. The upper opening of the pipe intersects with the main deck, and the lower opening intersects with the outer plate of the bow and extends to the anchor platform panel. Both the upper and lower openings form an elliptical pipe opening at the intersection. The anchor platform, the hawsepipe, and the anchor lip form a lifting and storing device for the anchor. The anchor is lifted in the direction of the hawsepipe. The depth of the hawsepipe and the anchor platform is used to store the anchor rod. The combination of the anchor platform panel and the anchor lip provides the final position and direction for storing the anchor. At the same time, the size of the anchor platform panel and the angle of the anchor platform coaming are determined by comprehensively considering factors such as the type and size of the anchor and the turning motion of the anchor during storage. Therefore, accurate lofting of the anchor platform determines whether the anchor platform can fit smoothly with the anchor lip, whether the anchor platform can fit tightly with the outer hull of the ship, and whether the anchor platform can be manufactured according to the design data of the anchoring principle. In the prior art, the manufacturing part drawing of the anchor platform will provide an anchor platform jig drawing for controlling the manufacturing accuracy of the anchor platform. Specifically, various curve projections are formed by projecting the anchor platform panel downward. During the manufacturing process of the anchor platform, the manufacturing accuracy is controlled by vertical alignment lines. The operation difficulty is relatively high, the accuracy is poor, and the material utilization rate is also relatively low. Summary of the Invention

[0003] In view of the above-mentioned disadvantages of the prior art, the present invention provides a manufacturing method of an anchor platform sample box. First, a sample box cross-section is selected on the anchor platform, and the anchor platform is divided into four pairwise opposite parts through the sample box cross-section, so as to obtain the profile sample box data of each part of the anchor platform. Then, profile splines are manufactured according to the profile sample box data. Finally, the profile splines are assembled into an anchor platform sample box. Compared with the prior art, the present invention can more effectively assist in the manufacturing of the anchor platform coaming and improve the manufacturing accuracy of the anchor platform.

[0055] Embodiment

[0056] This embodiment provides a method for manufacturing an anchor pedestal mock-up box, including the following steps:

[0057] S1: From one side of the anchor pedestal panel, project the anchor pedestal along the axis direction of the hawse pipe to obtain a first projection plane, obtain multiple cross-sections of the anchor pedestal passing through the axis of the hawse pipe, and number the projection lines of each cross-section on the first projection plane;

[0058] As Figure 1 shown, the anchor pedestal 10 is installed on the bow outer plate 20. The anchor pedestal 10 includes an anchor pedestal panel 11 and an anchor pedestal coaming 12, and the hawse pipe 30 is arranged in the anchor pedestal 10 and the bow outer plate 20.

[0059] First, from one side of the anchor pedestal panel 11, project the anchor pedestal 10 along the axis direction of the hawse pipe 30 to obtain the first projection plane 100 as Figure 2a shown. The first projection plane 100 includes the projection 101 of the lower edge of the anchor pedestal coaming, the projection 102 of the anchor pedestal panel, and the projection 103 of the hawse pipe.

[0060] Next, obtain multiple cross-sections of the anchor pedestal 10 passing through the axis of the hawse pipe 30, and number the projection lines of each cross-section on the first projection plane 100, as Figure 2a shown.

[0061] Next, according to the positions of the cross-sections, loft and develop each cross-section to obtain the contour line of each cross-section, as Figure 3 shown.

[0062] S2: From one side of the anchor pedestal panel, project the anchor pedestal along the direction perpendicular to the anchor pedestal panel to obtain a second projection plane, and correspondingly mark the cross-section projection lines obtained in step S1 on the second projection plane;

[0063] First, from one side of the anchor pedestal panel 11, project the anchor pedestal 10 along the direction perpendicular to the anchor pedestal panel 11 to obtain the second projection plane 200 as Figure 2b shown. The second projection plane 200 also includes the projection 201 of the lower edge of the anchor pedestal coaming, the projection 202 of the anchor pedestal panel, and the projection 203 of the hawse pipe.

[0064] Next, according to the contour lines of each section in step S1 and the lofting and unfolding relationship, the corresponding projection lines of the sections obtained in step S1 are marked on the second projection plane 200, as shown in reference to Figure 2b shown.

[0065] S3: Obtain a reference plane based on the first projection plane and the second projection plane, and select a rectangular sample box cross-section on the reference plane. Taking the four sides of the sample box cross-section as the reference, divide the anchor table into four pairwise-opposite parts: the first part, the second part, the third part, and the fourth part;

[0066] As Figure 4 shown, make the center point O of the hawsepipe in the first projection plane 100 coincide with the center point O of the hawsepipe in the second projection plane 200. Take the projection 101 of the lower edge of the anchor table coaming in the first projection plane 100 and the projection 202 of the anchor table panel in the second projection plane 200 to obtain the reference plane 300.

[0067] Next, select a rectangular sample box cross-section 301 on the reference plane 300. Considering saving sample box materials, on the reference plane 300, with the center point O of the hawsepipe as the center, taking the four sides of the sample box cross-section 301 as the reference, divide the anchor table 10 into four pairwise-opposite parts according to the curve shape of the projection 101 of the anchor table coaming. The first part is the part between number "3" and number "14" on the projection 101 of the anchor table coaming, the second part is the part between number "14" and number "f" on the projection 101 of the anchor table coaming, the third part is the part between number "f" and number "d" on the projection 101 of the anchor table coaming, and the fourth part is the part between number "d" and number "3" on the projection 101 of the anchor table coaming. Each part is made into a local sample box separately, rather than making the entire anchor table sample box. Because only the outer contour of the anchor table is needed for coaming production, the anchor table is appropriately intercepted. This can save materials as much as possible on the premise of meeting the function of the sample box. Finally, the local sample boxes of each part are overlapped according to their relative positions.

[0068] S4: According to the data of the reference plane in step S3, respectively obtain the cross-sectional sample box data of the first part, the second part, the third part, and the fourth part, and make cross-sectional splines for each part according to the cross-sectional sample box data;

[0069] As Figure 5As shown, according to the data of each part in the reference plane 300, the sectional sample box data of the first part 110, the sectional sample box data of the second part 120, the sectional sample box data of the third part 130, and the sectional sample box data of the fourth part 140 are obtained respectively. As an example, the auxiliary line L1 is a line passing through point O and parallel to the outer plate 20 of the bow; the distance between the auxiliary line L2 and the lowest point M of the intersection of the anchor platform coaming 12 and the outer plate 20 of the bow in each part is 100 mm; the auxiliary line L3 is the axis of the hawsepipe 30.

[0070] Next, sectional splines of each part are made according to the sectional sample box data of the first part 110, the sectional sample box data of the second part 120, the sectional sample box data of the third part 130, and the sectional sample box data of the fourth part 140 respectively.

[0071] As Figure 6 shown, the sectional spline 40 includes a top spline 41, a middle spline 42, and a bottom spline 43 connected in sequence, and the top spline 41 is hinged to the middle spline 42, and the middle spline 42 is hinged to the bottom spline 43, so as to facilitate adjusting the angle between the top spline 41 and the middle spline 42, and the angle between the middle spline 42 and the bottom spline 43.

[0072] As an example, the middle spline 42 includes a connected first spline 421 and a second spline 422. The first spline 421 and the second spline 422 are fixed by cooperating with fastening bolts to press the steel sheet, and the specific adjustable length range of the middle spline 42 is based on the value range of the length of the anchor platform coaming of the existing ship type. The length of the middle spline 42 can be adjusted by adjusting the relative position between the first spline 421 and the second spline 422. In this embodiment, first, the angle between the top spline 41 and the middle spline 42 is adjusted according to the angle between the anchor platform coaming alignment and the anchor platform panel, and then, according to the angle between the anchor platform coaming and the bottom spline 43 and the overall height of the anchor platform sample box, a bottom spline 43 with a suitable length is selected for bolt fixation, so as to obtain the sectional spline 40 of each part.

[0073] S5: Assemble the sectional splines of the first part, the second part, the third part, and the fourth part respectively to obtain a first local sample box, a second local sample box, a third local sample box, and a fourth local sample box respectively;

[0074] First, according to Figure 5 the sectional sample box data of each part shown, and the relative positions of each section, the first local sample box data, the second local sample box data, the third local sample box data, and the fourth local sample box data are integrated, as Figures 7a to 7d shown.

[0075] Next, according to Figures 7a to 7dThe first partial sample box data, the second partial sample box data, the third partial sample box data, and the fourth partial sample box data shown are assembled for the profile spline 40 produced in step S4 to obtain the first partial sample box, the second partial sample box, the third partial sample box, and the fourth partial sample box respectively.

[0076] S6: Assemble the first partial sample box, the second partial sample box, the third partial sample box, and the fourth partial sample box to obtain the anchor platform sample box.

[0077] As an example, assemble the first partial sample box, the second partial sample box, the third partial sample box, and the fourth partial sample box obtained in step S5 to finally obtain the anchor platform sample box. Since the lower end face heights of each partial sample box are inconsistent, when assembling, each partial sample box needs to be adjusted according to the relative position of the lower end face height to ensure the accuracy of the anchor platform sample box.

[0078] The above embodiments merely illustrate the principles and effects of the present invention and are not intended 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. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
