Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a method for installing a ship's side door and a ship. Background Technology

[0002] Ro-Ro car carriers are equipped with side doors on their hull sides, which serve as one of the loading and unloading channels for cars. The side door consists of the door body and outfitting components (hinges and power units, etc.). The door body is retracted and lowered via the outfitting components. The installation of these side doors requires high precision, primarily in two aspects: first, the matching degree of squareness between the side door body and the hull side; and second, the matching degree of the side door body's alignment with the hull side lines when retracted.

[0003] Currently, the common method for installing side doors is as follows: Firstly, the hull side is divided into main sections and multiple sub-sections. As assembly and installation work progresses, the installation area for the side door on the hull side takes shape. Secondly, during construction, the side door body needs to be manufactured according to design requirements, and its dimensions and flatness must be inspected and approved before being transported to the assembly site. When the side door is ready for hoisting, a crane is used to lift it, aligning the hinges and other outfitting components on the side door with the hinge eye plates on the hull side. Then, through multiple adjustments, the side door is adjusted to meet the requirements for use.

[0004] The aforementioned side door installation method has the following problems: First, during the construction of various hull structures, varying degrees of deformation may occur, resulting in a low degree of fit between the hull side and the side door. This necessitates extensive rework and adjustments to ensure the fit meets requirements, making the process cumbersome and inefficient. Second, if problems are discovered during the installation and adjustment of the side door, significant work at height is often required, posing safety hazards and reducing efficiency. Finally, the side door adjustment process occupies cranes for extended periods, leading to excessively low utilization rates of cranes and other lifting equipment.

[0005] Therefore, there is an urgent need for a method for installing ship side doors and a ship in order to solve the above problems. Summary of the Invention

The ship includes a side 10 and a side door. The side 10 is provided with a side opening 12, which connects to the ship's cabin. The side door includes a side door body 20 and a hinge seat 30. The hinge seat 30 is fixed to the bottom side edge of the side door body 20 and is rotatably connected to the side 10. The side door body 20 can close or open the side opening 12.

[0057] Figure 4A flowchart illustrating a ship side door installation method according to an embodiment of the present invention is shown. (Refer to...) Figures 2-4 This embodiment also provides a method for installing a ship's side door. The ship described above uses this method to assemble the side 10 and the ship's side door.

[0058] The method for installing ship side doors includes the following steps:

[0059] Step S10: The ship's side 10 is assembled and formed to create the side door installation area 11; the side door body 20 of the ship's side door is manufactured.

[0060] Step S20: Perform three-dimensional measurement on the side door installation area 11 to obtain the first measurement data; perform three-dimensional measurement on the side door body 20 to obtain the second measurement data.

[0061] Through the above steps, the structural features of the side door body 20 and the side door installation area 11 can be obtained before the side door of the ship is installed.

[0062] Figure 5 This diagram illustrates the first measurement data processing method for forming a simulated mounting position according to an embodiment of the present invention. (Refer to...) Figure 5 The first measurement data in step S20 includes the position of the installation area center line 1, the position of the installation area reference line 2, and the position of the feature points 3 on the periphery of the installation area. The installation area reference line 2 is set at an angle to the installation area center line 1.

[0063] Specifically, the center line 1 of the installation area is parallel to the vertical direction, and the reference line 2 of the installation area is set perpendicular to the center line 1 of the installation area, such as... Figure 2 As shown.

[0064] More specifically, multiple installation area reference lines 2 are set, and these reference lines 2 are set parallel to each other and spaced apart. This arrangement increases the amount of first measurement data, thereby increasing the accuracy of the three-dimensional measurement of the side door installation area 11 and facilitating the accuracy of subsequent sub-analysis of the first measurement data.

[0065] More specifically, multiple peripheral feature points 3 are set along the periphery of the side door installation area 11, such as... Figure 5 As shown. In this embodiment, eleven peripheral feature points 3 are specifically provided for the installation area. The aforementioned peripheral feature points 3 are specifically distributed at both ends of the installation area centerline 1, both ends of the installation area reference line 2, and both sides of the four apex corners of the side door installation area 11.

[0066] Figure 6 This diagram illustrates the second measurement data processing method for forming a simulated side door according to an embodiment of the present invention. (Refer to...) Figure 6The second measurement data in step S20 includes the position of the side door center line 4, the position of the side door reference line 5, and the position of the side door peripheral feature point 6. The side door reference line 5 is set at an angle to the side door center line 4.

[0067] Specifically, the side door centerline 4 is parallel to the vertical direction, and the side door reference line 5 is set perpendicular to the side door centerline 4, such as... Figure 3 As shown.

[0068] More specifically, multiple side door reference lines 5 are set, and these reference lines 5 are set parallel to each other and spaced apart. This arrangement increases the amount of second measurement data, thereby increasing the accuracy of the three-dimensional measurement of the side door body 20 and facilitating the accuracy of subsequent sub-analysis of the second measurement data.

[0069] More specifically, multiple side door peripheral feature points 6 are provided along the periphery of the side door body 20. For example... Figure 6 As shown, in this embodiment, eleven peripheral feature points 6 are specifically provided on the side door. These peripheral feature points 6 are specifically distributed at both ends of the side door centerline 4, both ends of the side door reference line 5, and both sides of the four apex corners of the side door body 20.

[0070] Step S30: Compare the first measurement data and the second measurement data, and adjust the structure of the side door mounting area 11 based on the second measurement data to correct the side door mounting area 11.

[0071] Specifically, between step S20 and step S30, the following also needs to be performed:

[0072] Step S21: Compare the second measurement data with the preset structural data, and adjust the structure of the side door body 20 based on the preset structural data to correct the side door body 20. In this embodiment, the structure of the side door body 20 can be corrected by cutting, opening, or replacing the sheet metal of the side door body 20.

[0073] Step S40: Hoist the side door body 20 and install it into the side door installation area 11.

[0074] Figure 7 This diagram illustrates the relative position adjustment of the simulated side door and the simulated mounting position according to an embodiment of the present invention. (Refer to...) Figure 7 Between step S30 and step S40, the following also needs to be performed:

[0075] Step S31: Based on the corrected side door mounting area 11, obtain the corrected first measurement data, process the corrected first measurement data, and process the second measurement data to form the simulated mounting position 7 and the simulated side door 8. The above steps are specifically performed in the simulated component, enabling the formation of... Figure 7 The simulated installation position 7 and simulated side door 8 are shown in the figure.

[0076] Step S32: Simulate the assembly of the simulated side door 8 and the simulated mounting position 7.

[0077] Step S33: Adjust the relative positions of the simulated side door 8 and the simulated installation position 7 to obtain the preset installation position result of the simulated side door 8.

[0078] Specifically, in this embodiment, such as Figure 7 As shown, ten adjustment points 9 are specifically set around the simulated side door 8 and the simulated mounting position 7. Taking the simulated side door 8 as a reference, two adjustment points 9 are set at each of the four sides of the simulated side door 8, and the two adjustment points 9 on the same side are spaced apart from each other. Taking the simulated mounting position 7 as a reference, the preset installation position of the simulated side door 8 can be obtained by adjusting the relative positions of the simulated side door 8 and the simulated mounting position 7 at the ten adjustment points 9.

[0079] After step S33, in step S40, "lifting and installing the side door body 20 to the side door installation area 11" includes:

[0080] Step S41: Based on the preset installation position result, form the preset installation position in the side door installation area 11;

[0081] Step S42: Hoist the side door body 20 and install it to the preset installation position.

[0082] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
