[0033] Embodiment 1

[0034] Figure 1 is a flowchart of a method for controlling the installation accuracy of a pedestal according to Embodiment 1 of the present invention. This embodiment is applicable to the situation of controlling the accuracy of the segmented main body and the pedestal during shipbuilding. This method can be executed by a pedestal installation accuracy control device, which can be implemented in the form of hardware and / or software, and the pedestal installation accuracy control device can be configured in a device. For example, the device can be a device with communication and computing capabilities such as a background server. As Figure 1 shown, the method includes:

[0035] S110. Obtain the reference data of the ship segmented main body in the target state; wherein, the target state is a stress-free inclined state; the reference data refers to the theoretical reference data for positioning.

[0036] In this solution, the ship segmented main body refers to the hull structure that is pre-divided into several independent and prefabricable structural units according to the design drawings during shipbuilding. These units are usually welded from materials such as steel plates and profiles and are components of the overall hull structure. Through segmented construction, the complex hull construction process can be decomposed into multiple simple parts, facilitating assembly line operations in the shipyard and improving construction efficiency and quality.

[0037] Among them, the target state is the stress-free inclined state, that is, after the completion of the main body of the ship section, it is in a stress-free free-inclined state. The installation level detection of the pedestal is directly carried out in the inclined state of the section main body. This avoids the extra work caused by the horizontal adjustment of the section, makes the detection not restricted by the section level, and greatly improves the construction convenience and efficiency.

[0038] In this embodiment, the reference data is used to determine the reference lines. The reference lines are a set of lines with clear geometric meanings pre-drawn on the plates or skeletons of the section during the section construction process to ensure the position accuracy and relative relationships of various structural components (such as ribs, longitudinal girders, decks, bulkheads, etc.), and usually include horizontal lines, vertical lines, center lines, rib inspection lines, etc.

[0039] Among them, Figure 2 is a schematic diagram of the reference lines provided in Embodiment 1 of the present application. As Figure 2 shown, the reference lines include transverse reference lines and longitudinal reference lines.

[0040] Furthermore, a method combining optical projection and mechanical scribing is adopted to mark the reference data of the ship section main body in the target state.

[0041] S120. Modify the reference data to obtain the target reference data.

[0042] In this solution, the target reference data after modification can be obtained by correcting the deviation of the reference data. Among them, the deviation may be caused by various factors such as measurement and environmental factors.

[0043] S130. Based on the target reference data, determine the pedestal installation position data of the ship section pedestal.

[0044] In this embodiment, the pedestal installation position data is used to determine the pedestal installation position line. The pedestal installation position line is a local positioning line defined for the ship section pedestal based on the reference lines. It is the refinement and extension of the reference lines in the specific installation link and directly guides the layout, pouring or installation of the pedestal.

[0045] Furthermore, during the ship construction process, when determining the pedestal installation position data of the ship section pedestal based on the target reference data, it is necessary to comprehensively consider the ship design drawings, the reference line system and the construction process requirements. Specifically, on the ship section main body, according to the values of each reference line, mark the positions of the pedestal installation position lines and connect them with straight lines to form the pedestal installation position lines.

[0046] In this solution, Figure 3 is a schematic diagram of the pedestal installation position line provided in Embodiment 1 of the present application. As Figure 3As shown in the figure, use a high-precision scribing device to scribe the base installation position line to ensure the accuracy of the reference line and the accuracy of the installation position line.

[0047] S140. Determine the base reference data of the ship section base; wherein, the base reference data refers to the data used to locate the base position.

[0048] In this solution, the base reference data refers to the data used to locate the base position, which is used to provide a unified and accurate detection reference for the base installation, and to standardize and normalize the installation detection reference.

[0049] Specifically, based on the principle of spatial vector transformation, make full use of the three-point coordinate transformation function built in the total station. By accurately inputting key data such as the coordinates of the fitting points and the transformation parameters, the accurate conversion of measurement data between different coordinate systems can be efficiently realized. After the data conversion is completed, a virtual measurement plane is constructed based on the conversion results, and this plane strictly follows the geometric constraint conditions of the ship section base design. Subsequently, using the projection function of the total station, the virtual measurement plane is accurately projected onto the surface of the adjustable horizontal reference benchmark. With the help of the scale markings on the benchmark and the real-time measurement feedback of the total station, the base reference data of the ship section base can be accurately obtained, providing a reliable basis for the high-precision installation and docking operations of the ship section.

[0050] S150. Install the ship section base based on the base installation position data, and use the base reference data to control the accuracy of the installed ship section base.

[0051] In this solution, the ship section base can be accurately hoisted and positioned according to the base installation position line. Then, in the form of pulling a steel wire according to the base reference data, measure the distance between the base surface and the steel wire, and accurately adjust the levelness of the base by adjusting the adjustable support device at the bottom of the base, so as to realize the accuracy control of the installed ship section base.

[0052] By constructing a unified base installation detection reference system, combining advanced data processing algorithms and high-precision measurement equipment, the differences in various detection equipment, different accuracy levels, and uneven skills of operators that lead to differences in measurement data are effectively reduced. The synchronization of self-inspection and special inspection data is effectively improved, and zero error of measurement data can be achieved. The number of rechecks and rework caused by data errors is effectively reduced, the construction efficiency is improved, and at the same time, the quality stability and reliability are ensured, and the high-quality acceptance of the hull section base installation operation is guaranteed.

[0053] Optionally, installing the ship section base based on the base installation position data and using the base reference data to control the accuracy of the installed ship section base includes:

[0054] Install the ship section base based on the base installation position data, and fix the ship section base using positioning clamps; wherein, the installation accuracy of the ship section base is controlled within 1 mm.

[0055] Measure the installed ship section base using the base reference data to determine the distance between the base surface and the adjustable horizontal reference benchmark corresponding to the base reference data.

[0056] In the case where the distance does not meet the preset accuracy control conditions, adjust the adjustable support device of the ship section base.

[0057] Specifically, accurately hoist and position the ship section base according to the base installation position line, and fix the ship section base using positioning clamps to ensure that the installation accuracy of the ship section base is controlled within ±1 mm.

[0058] Among them, the accuracy control conditions are used to constrain the distance between the base surface and the adjustable horizontal reference benchmark corresponding to the base reference data.

[0059] In this embodiment, Figure 4 is a schematic diagram of the base accuracy control provided in Embodiment 1 of the present application. As Figure 4 shown, in the form of pulling a steel wire according to the base reference data, measure the distance between the base surface and the steel wire. In the case where the distance does not meet the preset accuracy control conditions, precisely adjust the levelness of the base by adjusting the adjustable support device at the bottom of the base, thereby achieving the accuracy control of the installed ship section base.

[0060] In this solution, after the adjustment is completed, a professional accuracy technician uses equipment such as an electronic measuring ruler and a laser rangefinder for special detection, and compares the data according to the shipbuilding accuracy specification (SPS) to ensure that the base installation accuracy meets the accuracy tolerance requirements, and the flatness error is controlled within ±1 mm.

[0061] Furthermore, during the welding process, weld according to the sequence specified in the process and the fixed positions of the personnel to control the welding deformation. After welding is completed, comprehensively detect the forming state of the section main body and the base to ensure that the overall accuracy meets the tolerance standard. Among them, during the installation process, the accuracy control detection mainly uses tools such as a steel straightedge (accuracy ±0.5 mm), a square (perpendicularity accuracy ±0.1°), a tape measure (accuracy ±1 mm), and a powder line (used for precise scribing and positioning), and cooperates with customized auxiliary tooling (such as positioning jigs, measuring brackets, etc.) to meet the high-precision and diversified detection needs on site, and ensure the accuracy and reliability of the installation accuracy control.

[0062] The detection tools used mainly include steel straightedges, angle gauges, tape measures, chalk lines, steel wires, level rods, etc. Compared with expensive detection equipment such as total stations and laser theodolites, these tools are more portable, facilitating the carrying and operation of construction workers, effectively reducing the construction difficulty and labor intensity, and enabling construction workers to conduct on-site detection operations more conveniently. Through innovative measurement technologies and process optimization, the over-reliance on expensive detection equipment such as total stations and laser theodolites is reduced, and the equipment usage cost and maintenance costs and shutdown risks caused by equipment damage are lowered. At the same time, the requirement of full-process instrument assistance and cooperation, such as the need for a dedicated person to watch over the instrument and multiple people to cooperate in the operation, is avoided, effectively reducing the construction cost and the difficulty of precision control management.

[0063] Optionally, before obtaining the reference data of the ship section main body in the target state, the method further includes:

[0064] Determine the ship section main body and the ship section base, and perform precision control on the ship section main body and the ship section base.

[0065] Specifically, first, the plates are cut numerically. After cutting, the parts will flow to the corresponding areas according to the production code and be assembled into the section main body and base components in the corresponding areas. During the assembly process, precision control measurement and adjustment should be carried out synchronously to ensure that the precision of each component meets the requirements.

[0066] Furthermore, use a high-precision optical total station to measure the precision of each component of the base component. Once a substandard point is found, corrective measures are taken to ensure that the precision of the base component meets the standard.

[0067] In this solution, when manufacturing the section main body in the section production workshop, strictly control the section level and the installation precision of the reverse structure during the assembly stage. Only after all precision data meet the ship standard tolerances can welding operations be carried out to ensure the quality of the section main body.

[0068] By unifying the detection reference and reducing the measurement difference rate, the section manufacturing cycle can be effectively improved, rework can be reduced, and the operation efficiency can be increased.

[0069] The technical solution of the embodiment of the present invention is to obtain the reference data of the ship section main body in the target state, correct the reference data to obtain the target reference data, then determine the base installation position data of the ship section base based on the target reference data, and determine the base reference data of the ship section base. Install the ship section base based on the base installation position data, and use the base reference data to control the accuracy of the installed ship section base. By implementing this technical solution, the horizontal detection of the base installation can be directly carried out in the inclined state of the section. This avoids the extra work caused by the horizontal adjustment of the section, makes the detection not restricted by the section level, and greatly improves the convenience and efficiency of construction. Advanced measurement technology and precise data analysis are used to achieve precise control of welding deformation. The detection process is easy to operate and the process is clear, which is convenient for construction personnel to independently detect and adjust the flatness of the base in real time, realizing efficient self-inspection and self-control. By improving the synchronization of self-inspection and special inspection data. By optimizing the construction process, the section manufacturing cycle is shortened. Since the detection process has relatively low requirements for the skills of operators, construction personnel can quickly master and proficiently apply it, significantly improving the efficiency of detection and installation work, accelerating the overall construction progress of the section, and providing strong support for the production efficiency and economic benefits of the enterprise. Construction personnel can quickly collect horizontal data alone, predict the welding deformation state based on the horizontal data analysis, and can optimize the welding sequence in time to effectively reduce welding stress and deformation. This efficient welding quality control method not only improves the stability of welding quality, but also improves the efficiency and accuracy of welding quality control.

[0080] Specifically, use professional three-dimensional data analysis software to compare the three-dimensional coordinate data with the pre-set three-dimensional model data of the hull section. In this process, carry out data fitting work with the help of the least squares method to obtain a fitting result. Subsequently, according to the obtained fitting result, correct the three-dimensional coordinate data, and finally obtain the target three-dimensional coordinate data.

[0089] Specifically, the corrected coordinate data can be subjected to coordinate transformation according to pre-set coordinate transformation parameters to obtain target corrected coordinate data, and the deviation of the reference data can be corrected according to the size of the target corrected coordinate data to obtain the corrected target reference data.

[0090] By correcting the reference data, the accuracy of the data is improved.

[0092] S570. Determine the base reference data of the ship section base; wherein, the base reference data refers to the data for positioning the base position.

[0093] Specifically, based on the principle of spatial vector transformation, by making full use of the three-point coordinate transformation function built in the total station and accurately inputting key data such as fitting point coordinates and transformation parameters, the accurate conversion of measurement data between different coordinate systems can be efficiently achieved. After the data conversion is completed, a virtual measurement plane is constructed based on the conversion results, and this plane strictly follows the geometric constraint conditions of the ship section base design.

[0094] Optionally, determining the base reference data of the ship section base includes:

[0095] Select fitting data from the target three-dimensional coordinate data;

Figure 6 This is a schematic diagram of the fitting points provided in the second embodiment of the present application. As Figure 6 shown, the fitting points include fitting point 1, fitting point 2, and fitting point 3.

[0098] In this embodiment, Figure 7 This is a schematic diagram of the setting of the adjustable horizontal reference benchmark provided in the second embodiment of the present application. As Figure 7As shown in the figure, based on the principle of spatial vector transformation, by making full use of the three-point coordinate transformation function built into the total station, through accurately inputting key data such as the coordinates of the fitting points and transformation parameters, the precise conversion of measurement data between different coordinate systems can be efficiently achieved.
