Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shipbuilding, and particularly relates to a method for installing a ship double-bevel cut section outboard support structure. BACKGROUND

[0002] Ship section construction is a shipbuilding technology that divides a ship body into multiple independent sections and assembles the multiple independent sections together. In the construction process of the ship section, the installation precision of each structure is crucial, and the installation quality of the outboard support structure, as a key support component in the section assembly and loading stage, has a profound impact on the entire ship section construction process and the final ship quality. The outboard support structure includes a support seat and a docking column connected in sequence, the support seat is fixed to the annular end face of the ship section, and the docking column is used for docking and fixing with a gantry.

[0003] In the related art, the ship section is divided along the bow and stern direction, and combined with the streamline characteristics of the ship, the ship section appears as a double-bevel cut section. The annular face of the double-bevel cut section has an inclination angle in the bow and stern direction and the up and down direction. The outboard support structure abuts against the annular face of the double-bevel cut section to support the double-bevel cut section. In the actual installation process, due to insufficient understanding of the characteristics of the double-bevel cut section, the installer often ignores the angle requirements of the outboard support structure in the bow and stern direction and the up and down direction, and simply installs the outboard support structure perpendicular to the ground. This incorrect installation method causes the actual installation angle of the outboard support structure to deviate from the design angle, which not only affects the support effect of the support seat on the double-bevel cut section, but also affects the docking and fixing of the docking column and the gantry, and further affects the production quality of the ship.

[0004] Therefore, it is urgent to invent a method for installing a ship double-bevel cut section outboard support structure to solve the above problems. SUMMARY

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0047] In the process of ship section construction, the installation accuracy of each structure is crucial, and the installation quality of the outboard support structure as a key support component in the section assembly and loading stage has a profound impact on the entire ship section construction process and the final ship quality. The outboard support structure includes a support seat and a docking column connected in turn. The support seat is fixed to the annular end surface of the ship section, and the docking column is used to dock and fix with the gantry. The ship section may be a double-bevel cut section. The annular surface of the double-bevel cut section has an inclination angle in the bow-stern direction and the up-down direction. The outboard support structure abuts against the annular surface of the double-bevel cut section to support the double-bevel cut section. In the actual installation process, due to insufficient understanding of the characteristics of the double-bevel cut section, the installation personnel often ignore the angle requirements of the outboard support structure in the bow-stern direction and the up-down direction, and simply install the outboard support structure perpendicular to the ground. This incorrect installation method causes the actual installation angle of the outboard support structure to deviate from the design angle, which not only affects the support effect of the support seat on the double-bevel cut section, but also affects the docking and fixing of the docking column with the gantry, and further affects the production quality of the ship.

[0048] To solve the above problems, as shown in Figs. 1-3 The embodiment provides an installation method of a ship double-bevel cut section outboard support structure.

[0049] S1, determining first theoretical position information of the support seat 110 and second theoretical position information of the docking column 120 according to design drawings and arrangement positions of the jig frame respectively;

[0050] S2, setting the support seat 110 at the annular surface of the ship double-bevel cut section 200 according to the first theoretical position information;

[0051] S3, measuring first actual position information of the support seat 110 and adjusting the position of the support seat 110, so that the first actual position information is the same as the first theoretical position information;

[0052] S4, setting the docking column 120 at the support seat 110 according to the second theoretical position information;

[0053] S5, measuring second actual position information of the docking column 120 and adjusting the position of the docking column 120, so that the second actual position information is the same as the second theoretical position information;

[0054] S6, three-dimensional simulation of the ship double-bevel cut section 200 and the outboard support structure 100, to obtain first simulation position information of the support seat 110 and second simulation position information of the docking column 120;

[0055] S7, adjust the position of the support seat 110 and the butt joint column 120 so that the deviation between the first actual position information and the first simulated position information is within the first preset range and the deviation between the second actual position information and the second simulated position information is within the second preset range.

[0056] The installation method of the ship double-bevel cut segment outboard support structure can provide an installation reference for the installation of the support seat 110 and the butt joint column 120 by determining the first theoretical position information of the support seat 110 and the second theoretical position information of the butt joint column 120 according to the data of the design drawing and the arrangement information of the jig. The installation accuracy of the support seat 110 can be ensured by measuring the first actual position information of the support seat 110 after the support seat 110 is arranged at the annular surface of the ship double-bevel cut segment 200 according to the first theoretical position information and adjusting the position of the support seat 110 so that the first actual position information is the same as the first theoretical position information. The installation accuracy of the butt joint column 120 can be ensured by measuring the second actual position information of the butt joint column 120 after the butt joint column 120 is arranged at the support seat 110 according to the second theoretical position information and adjusting the position of the butt joint column 120 so that the second actual position information is the same as the second theoretical position information. The installation accuracy of the outboard support structure 100 and the ship double-bevel cut segment 200 can be ensured by ensuring that the deviation between the first actual position information and the first simulated position information is within the first preset range and ensuring that the deviation between the second actual position information and the second simulated position information is within the second preset range, thereby ensuring the production quality of the ship. It should be noted that in the present embodiment, the first preset range is -5mm-5mm and the second preset range is -5mm-5mm. In other embodiments, the specific values of the first preset range and the second preset range can be adjusted according to actual needs, and the present embodiment is not limited in this regard.

[0057] In S3 in the present embodiment, if the first actual position information is the same as the first theoretical position information, the position of the support seat 110 does not need to be adjusted. If the first actual position information is different from the first theoretical position information, the position of the support seat 110 is adjusted until the first actual position information is the same as the first theoretical position information.

[0058] Specifically, the first theoretical position information comprises a first theoretical installation position of the support seat 110 on the annular surface of the ship double-bevel cut segment 200, and a first theoretical tilt angle in a first direction and a second theoretical tilt angle in a second direction at the first theoretical installation position. The first actual position information comprises a first actual installation position of the support seat 110 on the annular surface of the ship double-bevel cut segment 200, and a first actual tilt angle in the first direction and a second actual tilt angle in the second direction at the first actual installation position. The first simulated position information comprises a first simulated installation position of the support seat 110 on the annular surface of the ship double-bevel cut segment 200, and a first simulated tilt angle in the first direction and a second simulated tilt angle in the second direction at the first simulated installation position; any one of the first direction and the second direction is parallel to the bow-stern direction of the ship.

[0059] By making the first theoretical position information comprise a first theoretical installation position of the support seat 110 on the annular surface of the ship double-bevel cut segment 200, and a first theoretical tilt angle in a first direction and a second theoretical tilt angle in a second direction at the first theoretical installation position, and ensuring that the first direction and the second direction are perpendicular to each other and any one of them is parallel to the bow-stern direction of the ship, the tilt direction of the support seat 110 can be adapted to the tilt direction of the annular surface of the ship double-bevel cut segment 200. In combination with the first actual position information comprising a first actual installation position and a first actual tilt angle in the first direction and a second actual tilt angle in the second direction at the first actual installation position, and the first simulated position information comprising a first simulated installation position and a first simulated tilt angle in the first direction and a second simulated tilt angle in the second direction at the first simulated installation position, the installation precision between the support seat 110 and the ship double-bevel cut segment 200 can be ensured.

[0060] It should be noted that in the embodiment, the first direction is parallel to the bow-stern direction of the ship. In other embodiments, the second direction can also be parallel to the bow-stern direction of the ship, which is not limited in the embodiment.

[0061] In an optional solution, an angle ruler is used to check whether the first theoretical tilt angle is the same as the first actual tilt angle, and an angle ruler is used to check whether the second theoretical tilt angle is the same as the second actual tilt angle. By using an angle ruler to check whether the first theoretical tilt angle is the same as the first actual tilt angle and to check whether the second theoretical tilt angle is the same as the second actual tilt angle, respectively, the checking difficulty can be reduced and the checking efficiency can be improved.

[0062] In an actual operation scenario, the annular surface of the ship double-bevel cut segment 200 is an irregular surface. In order to ensure the profiling adaptation of the support seat 110 and the annular surface, the upper end surface of the support seat 110 which is in abutment with the annular surface also needs to be an irregular surface. In order to facilitate the angle detection of the angle ruler, in S3, the measuring surface of the support seat 110 is the lower end surface of the support seat 110, and the abutment column 120 is fixedly connected with the lower end surface of the support seat 110.

[0063] Specifically, when it is necessary to verify whether the first theoretical inclination angle is the same as the first actual inclination angle, first, the reference of the angle ruler is adjusted according to the first theoretical inclination angle, and then the measuring surface of the angle ruler is fitted with the lower end surface of the support seat 110, and it is observed whether the display bubble in the angle ruler is centered. If the display bubble is centered, it indicates that the first theoretical inclination angle is the same as the first actual inclination angle. If the display bubble is not centered, the position of the support seat 110 needs to be adjusted until the display bubble is centered. By first installing the reference of the angle ruler adjusted according to the first theoretical inclination angle, and then fitting the measuring surface of the angle ruler with the lower end surface of the support seat 110, and observing whether the display bubble in the angle ruler is centered to determine whether the first actual inclination angle is parallel to the first theoretical inclination angle, the purpose of verifying whether the first theoretical inclination angle is the same as the first actual inclination angle is achieved, which is simple in operation and high in detection accuracy.

[0064] Similarly, the operation steps of verifying the second theoretical inclination angle and the second actual inclination angle are the same as the operation steps of verifying the first theoretical inclination angle and the first actual inclination angle described above. One round of verification operation is completed by completing the verification of the first theoretical inclination angle and the first actual inclination angle once and completing the verification of the second theoretical inclination angle and the second actual inclination angle once. In actual operation, multiple rounds of verification operations need to be performed to ensure that the first theoretical inclination angle is the same as the first actual inclination angle and the second theoretical inclination angle is the same as the second actual inclination angle.

[0065] In this embodiment, the support seat 110 and the ship double-bevel cut segment 200 are fixedly connected in a welding manner. The welding fixation between the support seat 110 and the ship double-bevel cut segment 200 can ensure the fixation effect between the support seat 110 and the ship double-bevel cut segment 200 while having a sufficiently high structural strength,

[0066] As an alternative, after the welding and fixing of the support base 110 and the ship double-bevel cut segment 200 is completed, the first actual position information is rechecked and the structural strength of the support base 110 and the ship double-bevel cut segment 200 is detected. By rechecking the first actual position information of the support base 110 and detecting the structural strength between the support base 110 and the ship double-bevel cut segment 200 after the welding and fixing of the support base 110 and the ship double-bevel cut segment 200 is completed, the installation precision and the structural strength between the support base 110 and the ship double-bevel cut segment 200 can be ensured, and the production quality and the production safety of the ship can be ensured. It should be noted that if the rechecking information of the first actual position information is different from the original first actual position information, the positions of the support base 110 and the ship double-bevel cut segment 200 need to be adjusted to ensure that the rechecking information of the first actual position information is the same as the original first actual position information. If the structural strength of the support base 110 and the ship double-bevel cut segment 200 is unqualified, the welding and fixing of the support base 110 and the ship double-bevel cut segment 200 needs to be reperformed, and after the welding and fixing is completed, the first actual position information rechecking and the detection of the structural strength of the support base 110 and the ship double-bevel cut segment 200 are performed again until the structural strength between the support base 110 and the ship double-bevel cut segment 200 meets the requirements and the first actual position information of the support base 110 remains unchanged.

[0067] In addition, in S5 of the present embodiment, if the second actual position information is the same as the second theoretical position information, the position of the docking column 120 does not need to be adjusted; if the second actual position information is different from the second theoretical position information, the position of the docking column 120 is adjusted until the second actual position information is the same as the second theoretical position information. Moreover, the specific type of the second theoretical position information of the docking column 120 is the same as that of the first theoretical position information, the specific type of the second actual position information is the same as that of the first actual position information, and the specific type of the second simulated position information is the same as that of the first simulated position information. To ensure brevity, they will not be described here.

[0068] Moreover, whether the theoretical inclination angle and the actual inclination angle in the docking column 120 are the same is verified by using an angle gauge. The measurement surface of the docking column 120 is the lower end surface of the docking column 120, and the upper end surface of the docking column 120 and the lower end surface of the support base 110 are welded and fixed. The operation steps of using the angle gauge to verify whether the theoretical inclination angle and the actual inclination angle in the docking column 120 are the same are the same as those of using the angle gauge to verify whether the theoretical inclination angle and the actual inclination angle of the support base 110 are the same. To ensure brevity, they will not be described here.

[0069] The support seat 110 and the butt joint column 120 are fixedly connected in a welding manner, and after the fixed connection of the support seat 110 and the butt joint column 120 is completed, the second actual position information is rechecked, and the structural strength of the support seat 110 and the butt joint column 120 is detected.

[0070] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present application. Here, it is not necessary and also impossible to exhaust all the implementation modes. Any modification, equivalent substitution and improvement within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
