Description

Technical Field

[0001] The present application relates to the field of shipbuilding technology, and in particular to a method for assembling a large-line hyperbolic segment of a shuttle tanker. Background Art

[0002] Shuttle tankers are a type of ship specially used to transport oil from offshore oil fields to land. They are mainly known for their high maneuverability and are mainly used for transportation between floating storage and offloading vessels at offshore oil fields and ports. They can transport crude oil in seas with complex sea conditions.

[0003] In the field of shuttle tanker repair, the segments of the bow and stern are usually hyperbolic and have large linear shapes. During the assembly process, there is no measurement benchmark in the three directions of XYZ. During the assembly, the segments are usually adjusted to the theoretical height using steel supports based on the outer plate value.

[0004] In the prior art, due to the large segmented linear shape of the shuttle and the hyperbolic surface, the height difference of the steel support usually reaches more than 10 meters, which makes on-site construction inconvenient and dangerous. Due to the hyperbolic surface, there is no accurate measurement of the axis construction benchmark when the multiple segments are grouped together. Usually, it is necessary to use the precision control personnel to use the total station to measure the overall data, and take the data back to the office computer for analysis. The on-site workers need to wait for the precision control analysis results. After the data analysis is completed, the segment accuracy is adjusted according to the deviation on site, and the operation is repeated until the accuracy data is qualified.

[0005] In summary, the existing large-line hyperbolic segmented assembly method for shuttle tankers is inefficient, and due to the large number of equipment on the loading site and complex working conditions, it is dangerous and unsafe for on-site operators to frequently travel back and forth between the loading site and the office. Summary of the invention

[0006] In order to improve the efficiency and safety of assembling a large linear hyperboloid segment assembly of a shuttle tanker, the present application provides a method for assembling a large linear hyperboloid segment assembly of a shuttle tanker.

[0007] The present application provides a method for assembling a large-line hyperbolic section of a shuttle tanker using the following technical solution:

[0008] A method for assembling a large-line hyperbolic surface of a shuttle tanker by segmentation mainly comprises the following steps:

[0009] Step S1: Establish a cloud platform to store segment information, wherein the segment information includes segment name, segment position in the overall assembly, segment three-dimensional data, segment outer plate value point data, and segment assembly order;

[0010] Step S2: Select the first segment, select a plurality of outer plate key points from the outer plate type value point data of the first segment, implant reflectors at the outer plate key points of the first segment, set a general assembly steel pier based on the first segment in the loading site, and install the first segment on the general assembly steel pier;

[0011] Step S3: import the actual coordinate data of multiple key points of the outer plate on the first segment in the loading site into the analysis software, import the three-dimensional data model and the outer plate type value point data of the second segment into the analysis software, select two precision control points from the outer plate type value point data of the second segment, implant reflectors on the two precision control points respectively, and obtain the on-site positioning theoretical data of the two precision control points on the second segment through the three-point moving function of the total station;

[0012] Step S4: Based on the on-site positioning theoretical data, obtain the coordinate data of multiple appearance key points on the first segment and the coordinate data of two precision control points on the second segment, compare the deviation between the actual coordinate data of the second segment on site and the on-site positioning theoretical data, adjust the position of the second segment along the width direction, height direction and length direction, and effectively seal the first segment and the second segment.

[0013] By adopting the above technical solution, in the process of assembling the segments into the total group, the operator can retrieve the segment information of each segment from the cloud platform, and select the first segment based on the site conditions of the loading site, the position of each segment in the total group, and the assembly order of each segment, and set the total group steel piers for carrying and supporting the total group at the loading site based on the outer plate type value data of the first segment. After the first section is mounted and installed on the steel pier for the general assembly by a crane, the actual coordinate data of multiple key points of the outer plate on the first section can be detected by a total station; after the measured model and the design model of the first section are integrated in the analysis software, the on-site positioning theoretical data of the two precision control points on the second section after the second section is installed at the mounting site can be obtained; when the crane transports the second section to the mounting site, the operator can use the total station to detect the effects of multiple key points of the outer plate and the two precision control points, and by adjusting the models of the first section and the second section in the total station, the deviation between the measured coordinate values ​​of the two precision control points on the second section and the on-site positioning theoretical data can be grasped, so that relevant personnel can adjust the second section along the length direction, width direction and height direction according to the deviation between the measured coordinate values ​​of the two precision control points and the on-site positioning theoretical data, until the coordinate positions of the two precision control points on the second section match the on-site positioning theoretical data; after the placement and installation of the second section are completed, the first section and the second section are effectively sealed, so that the mounting and installation of the first section and the second section can be realized. Through the above-mentioned technical means, it is possible to avoid on-site operators from frequently traveling back and forth between the loading site and the office during the loading of the second segment, thereby reducing the occurrence of on-site operators being injured due to frequent traveling back and forth between the loading site and the office. It can effectively save the time and effort required to adjust the position of the second segment, improve the efficiency of assembly between the second segment and the first segment, and shorten the construction period for assembling the segments into a general group.

[0014] Preferably, step S2 comprises the following steps:

[0015] Step S21: obtaining segmentation information of each segment from the cloud platform, and determining the first segment based on the segmentation information;

[0016] Step S22: acquiring the three-dimensional data and the external plate type value point data of the first segment from the cloud platform, and importing the three-dimensional data and the external plate type value point data of the first segment into the total station;

[0017] Step S23: selecting a plurality of outer plate key points from the outer plate type value point data of the first segment, the number of the outer plate key points is at least three, and the plurality of outer plate key points include a first reference point and a second reference point, the first reference point is a point with a negative value and the largest absolute value of the Y-axis coordinate in the outer plate type value point data of the first segment, and the Y-axis coordinate value and the Z-axis coordinate value of the second reference point are the same as the Y-axis coordinate value and the Z-axis coordinate value of the first reference point;

[0018] Step S24: transporting the first segment to a preset position for installing the first segment at the loading site by a crane, and adjusting the position of the first segment along the length direction, height direction, and width direction so that the outer plates of the first segment at multiple outer plate key points are substantially horizontal when visually observed;

[0019] Step S25: setting a steel pier for the assembly at the loading site, and the steel pier for the assembly is set close to the outer plate near the first reference point;

[0020] Step S26: setting up piers for supporting the first segment on the main assembly steel piers and loosening the hooks to release the first segment.

[0021] By adopting the above technical solution, by implanting reflective sheets at key points of the outer panels on the first segment, it is convenient for operators to adjust the first segment to a roughly horizontal position during the installation of the first segment; by setting the steel pier for the general assembly based on the position of the first key point, since the Y-axis coordinate of the first key point is a negative number and the absolute value of the Y-axis coordinate value of the first key point is the largest, when the first segment is adjusted to be roughly horizontal, the first key point is located at the lowest point of the first segment, which can make the height of the steel pier for the general assembly lowered; after completing the installation of the first segment, by implanting reflective sheets at key points of the outer panels on the first segment, it is convenient for operators to measure the coordinate data of key points of the outer panels on the first segment through a total station.

[0022] Preferably, step S3 comprises the following steps:

[0023] Step S31: using a total station to detect the first segment after installation at the installation site, and obtaining coordinate data of multiple key points of the outer panel on the first segment;

[0024] Step S32: importing the three-dimensional models of the first segment and the second segment into the analysis software in the office, and hiding the second segment;

[0025] Step S33: import the coordinate data of multiple key points of the outer plate on the first segment after installation into the analysis software, move the positions of the first segment and the second segment in the analysis software, so that the coordinates of the key points of the outer plate on the design model of the first segment coincide with the coordinates of the key points of the outer plate in the first segment installation site, cancel the hidden state of the second segment, select two precision control points from the outer plate type value point data of the second segment, and the two precision control points are located at the bow end of the outer plate of the second segment, export the coordinates of the two precision control points from the analysis software and calibrate them as on-site positioning theoretical data;

[0026] Step S34: Print the on-site positioning theoretical data into a report and bring it to the installation site.

[0027] By adopting the above technical solution, by adjusting the design model of the first segment in the analysis software to coincide with the design model of the first segment, a preset model of the second segment after installation at the mounting site can be obtained, and by setting and implanting two precision control points on the second segment, the position of the second segment can be easily verified at the mounting site.

[0028] Preferably, the step S33 comprises the following steps:

[0029] Step S331: Select a first reference point and a second reference point to rotate the design model of the first segment 90 degrees around the X-axis;

[0030] Step S332: using a point moving function of the analysis software, the X-axis coordinate, Y-axis coordinate, and Z-axis coordinate of the first reference point of the design model of the first segment and the actual first reference point in the loading site of the first segment are all moved to 0;

[0031] Step S333: Select a third reference point from a plurality of key points of the outer plate of the first segment, the first reference point, the second reference point, and the third reference point on the first segment in the loading site form a measured reference plane, the first reference point, the second reference point, and the third reference point in the design model on the first segment form a design reference plane, and use the three-point moving function of the analysis software to move the Z-axis coordinate values ​​of the first reference point, the second reference point, and the third reference point to 0, so that the design reference plane of the first segment coincides with the measured reference plane;

[0032] Step S334: displaying the hidden display state of the second segment, and selecting two precision control points from the outer plate value point data of the second segment;

[0033] Step S335: implanting reflective sheets at two precision-controlled points on the outer plate of the second segment.

[0034] By adopting the above technical solution, the design model of the first segment is rotated 90 degrees around the X-axis, and then the X-axis coordinate value, Y-axis coordinate value, and Z-axis coordinate value of the first reference point on the design model of the first segment and the first reference point on the first segment at the measured site are all moved to 0; when the design reference plane is overlapped with the measured reference plane, the design model of the first segment can be overlapped with the measured model of the first segment. At this time, the display status of the second segment is modified to display, and the coordinates of the two precision control points on the second segment in the analysis software are the theoretical data for on-site positioning.

[0035] Preferably, step S4 comprises the following steps:

[0036] Step S41: transporting the second segment to the loading site by a crane, adjusting the position of the second segment along the length direction, width direction, and height direction, and roughly positioning the position of the second segment;

[0037] Step S42: Detecting actual coordinate data of multiple key points of the outer plate on the first segment and two precision control points on the second segment by using a total station;

[0038] Step S43: comparing the positions of the two precision control points on the second segment in the total station to determine the deviation between the actual position of the second segment in the mounting site and the preset installation position;

[0039] Step S44: Based on the deviation between the actual position of the second segment in the loading site and the preset position, the position of the second segment is adjusted along the length direction, the width direction and the height direction by a crane until the coordinate data of the two precision control points on the second segment in the total station are the same as the coordinate data of the precision control points on the second segment in the design model;

[0040] Step S45: Arrange piers for supporting the second segment on the steel piers for the general assembly, loosen the hook to release the second segment, and effectively seal the first segment and the second segment.

[0041] By adopting the above technical scheme, during the installation of the second segment, since reflectors are arranged on the two precision control points on the second segment, the measured coordinate values ​​of the two precision control points on the second segment can be measured by the total station. After the measured coordinate values ​​of the two precision control points are imported into the total station, the three-point movement of the measured first segment and the second segment can be performed, and the coordinate values ​​of the two precision control points after the three-point movement can be compared with the theoretical data of on-site positioning. By comparing the coordinate values ​​of the two precision control points after the three-point movement with the theoretical data of on-site positioning, the deviation between the second segment and the preset installation position can be obtained, so that the on-site operator can adjust the position of the second segment along the length, width and height directions according to the deviation.

[0042] Preferably, the step S42 comprises the following steps:

[0043] Step S421: Detecting the coordinate data of the first key point, the second key point, the third key point and two precision control points at the site by using a total station;

[0044] Step S422: Select the first key point, the second key point and the third key point in the total station to move the three points, move the Z-axis coordinate values ​​of the first key point, the second key point and the third key point to 0, and obtain the actual coordinate data of the two precision control points on the second segment.

[0045] Preferably, the height of the first reference point from the ground of the loading site is not less than 900 mm, and the height of the total assembly steel pier is not less than 900 mm.

[0046] In summary, the present invention provides a method for assembling a large-line hyperbolic segmented shuttle tanker, which includes at least one of the following beneficial technical effects:

[0047] 1. It can avoid the on-site operators from frequently traveling back and forth between the loading site and the office during the loading of the second segment, reduce the chances of on-site operators being injured due to frequent traveling back and forth between the loading site and the office, effectively save the time and effort required to adjust the position of the second segment, improve the efficiency of assembling the second segment with the first segment, and shorten the construction period of assembling the segments into a total group;

[0048] 2. By implanting reflective sheets on the key points of each outer panel on the first segment and on the two precision control points on the second segment, it is convenient to detect the actual coordinates of the key points of each outer panel on the first segment and the precision control points on the second segment by a total station at the loading site.

[0053] The following is combined with Figure 1-3 This application is described in further detail.

[0054] Example 1

[0055] The present application embodiment discloses a method for assembling a large-line hyperbolic segment of a shuttle tanker. Figure 1 , which mainly includes the following steps:

[0056] Step S1: Establish a cloud platform to store segment information, including segment name, segment position in the overall assembly, segment three-dimensional data, segment outer plate value point data, and segment assembly sequence;

[0057] Step S2: Select the first segment 1, select a plurality of outer plate key points from the outer plate type value point data of the first segment 1, implant reflective sheets at the outer plate key points of the first segment 1, set a general assembly steel pier based on the first segment 1 in the loading site, and install the first segment 1 on the general assembly steel pier;

[0058] Step S3: import the actual coordinate data of multiple key points of the outer plate on the first segment 1 in the loading site into the analysis software, import the three-dimensional data model and the outer plate type value point data of the second segment 2 into the analysis software, select two precision control points from the outer plate type value point data of the second segment 2, implant reflectors at the two precision control points respectively, and obtain the on-site positioning theoretical data of the two precision control points on the second segment 2 through the three-point moving function of the total station;

[0059] Step S4: Based on the on-site positioning theoretical data, obtain the coordinate data of multiple appearance key points on the first segment 1 and the coordinate data of two precision control points on the second segment 2, compare the deviation between the actual coordinate data of the second segment 2 on site and the on-site positioning theoretical data, adjust the position of the second segment 2 along the width direction, height direction and length direction, and effectively seal the first segment 1 and the second segment 2.

[0060] In the process of assembling the segments into the total group, the operator can retrieve the segment information of each segment from the cloud platform, and select the first segment 1 based on the site conditions of the loading site, the position of each segment in the total group, and the assembly order of each segment, and set the total group steel piers for carrying and supporting the total group at the loading site based on the outer plate type value data of the first segment 1; after the first segment 1 is loaded and installed on the total group steel pier by a crane, the actual coordinate data of multiple outer plate key points on the first segment 1 can be detected by a total station.

[0061] After integrating the measured model and the design model of the first segment 1 in the analysis software, the on-site positioning theoretical data of two precision control points on the second segment 2 after the second segment 2 is installed on site can be obtained.

[0062] After the crane transports the second section 2 to the loading site, the operator can use the total station to detect the effects of multiple key points of the outer plate and the two precision control points. By adjusting the models of the first section 1 and the second section 2 in the total station, the deviation between the measured coordinate values ​​of the two precision control points on the second section 2 and the theoretical data of on-site positioning can be grasped, which is convenient for relevant personnel to adjust the second section 2 along the length, width and height directions according to the deviation between the measured coordinate values ​​of the two precision control points and the theoretical data of on-site positioning until the coordinate positions of the two precision control points on the second section 2 match the theoretical data of on-site positioning.

[0063] After the second section 2 is placed and installed, the first section 1 and the second section 2 are effectively sealed, so that the first section 1 and the second section 2 can be loaded and installed.

[0064] Through the above-mentioned technical means, it is possible to avoid on-site operators from frequently traveling back and forth between the loading site and the office during the process of loading the second section 2, reduce the occurrence of on-site operators being injured due to frequent traveling back and forth between the loading site and the office, effectively save the time and effort required to adjust the position of the second section 2, improve the efficiency of assembly between the second section 2 and the first section 1, and shorten the construction period for assembling the sections into a general group.

[0065] Wherein, step S2 comprises the following steps:

[0066] Step S21: Obtain segment information of each segment from the cloud platform, and determine the first segment 1 based on the segment information;

[0067] Step S22: acquiring the three-dimensional data and the external plate type value point data of the first segment 1 from the cloud platform, and importing the three-dimensional data and the external plate type value point data of the first segment 1 into the total station;

[0068] Step S23: selecting a plurality of outer plate key points from the outer plate type value point data of the first segment 1, the number of the outer plate key points is at least three, and the plurality of outer plate key points include a first reference point and a second reference point, the first reference point is a point with a negative value and the largest absolute value of the Y-axis coordinate in the outer plate type value point data of the first segment 1, and the Y-axis coordinate value and the Z-axis coordinate value of the second reference point are the same as the Y-axis coordinate value and the Z-axis coordinate value of the first reference point;

[0069] Step S24: transporting the first segment 1 to a preset installation position of the first segment 1 at the loading site by a crane, and adjusting the position of the first segment 1 along the length direction, height direction, and width direction so that the outer panels of the first segment 1 at multiple outer panel key points are substantially horizontal when visually observed;

[0070] Step S25: setting a steel pier for the assembly at the loading site, and the steel pier for the assembly is set close to the outer plate near the first reference point;

[0071] Step S26: setting the piers for supporting the first section 1 on the steel piers of the general assembly and loosening the hooks to release the first section 1.

[0072] By implanting reflective sheets at key points of the outer panels on the first segment 1, it is convenient for operators to adjust the first segment 1 to a roughly horizontal position during the installation of the first segment 1; by setting the steel pier for the general assembly based on the position of the first key point, since the Y-axis coordinate of the first key point is a negative number and the absolute value of the Y-axis coordinate value of the first key point is the largest, when the first segment 1 is adjusted to be roughly horizontal, the first key point is located at the lowest point of the first segment 1, which can make the height of the steel pier for the general assembly lowered; after completing the installation of the first segment 1, by implanting reflective sheets at key points of the outer panels on the first segment 1, it is convenient for operators to measure the coordinate data of the key points of the outer panels on the first segment 1 through a total station.

[0073] For example, Figure 2 The first section 1 of the bottom of the shuttle tanker is shown. The first section 1 is assembled first in the overall assembly process. Four key outer plate points are set on the first section 1, and the four key outer plate points are P1, P2, P3 and P4. Among them, P1 and P3 are located at the structural intersection of the stern end of the outer plate of the first section 1, and P2 and P4 are located at the structural intersection of the bow end of the outer plate of the second section 2.

[0074] It should be noted that, in this embodiment, the height of the first reference point from the ground of the loading site is not less than 900 mm, and the height of the steel pier for the general assembly is not less than 900 mm, which can facilitate on-site operators to carry out construction.

[0075] Wherein, step S3 comprises the following steps:

[0076] Step S31: using a total station to detect the first segment 1 after installation at the installation site, and obtaining coordinate data of multiple key points of the outer panel on the first segment 1;

[0077] Step S32: importing the three-dimensional models of the first segment 1 and the second segment 2 into the analysis software in the office, and hiding the second segment 2;

[0078] Step S33: import the coordinate data of multiple key points of the outer plate on the first segment 1 after installation into the analysis software, move the positions of the first segment 1 and the second segment 2 in the analysis software, so that the coordinates of the key points of the outer plate on the design model of the first segment 1 coincide with the coordinates of the key points of the outer plate in the first segment 1 installation site, cancel the hidden state of the second segment 2, select two precision control points from the outer plate type value point data of the second segment 2, and the two precision control points are located at the bow end of the outer plate of the second segment 2, export the coordinates of the two precision control points from the analysis software and calibrate them as the on-site positioning theoretical data;

[0079] Step S34: Print the on-site positioning theoretical data into a report and bring it to the installation site.

[0080] By adjusting the design model of the first segment 1 in the analysis software to coincide with the design model of the first segment 1, a preset model of the second segment 2 after installation at the mounting site can be obtained; by setting and implanting two precision control points on the second segment 2, the position of the second segment 2 can be easily verified at the mounting site.

[0081] Wherein, step S33 comprises the following steps:

[0082] Step S331: Select the first reference point and the second reference point to rotate the design model of the first segment 1 by 90 degrees around the X axis;

[0083] Step S332: using a point moving function of the analysis software, the X-axis coordinate, Y-axis coordinate, and Z-axis coordinate of the first reference point of the design model of the first segment 1 and the actual first reference point in the loading site of the first segment 1 are all moved to 0;

[0084] Step S333: Select a third reference point from a plurality of key points of the outer plate of the first segment 1, the first reference point, the second reference point, and the third reference point on the first segment 1 in the loading site form a measured reference plane, the first reference point, the second reference point, and the third reference point in the design model on the first segment 1 form a design reference plane, and use the three-point moving function of the analysis software to move the Z-axis coordinate values ​​of the first reference point, the second reference point, and the third reference point to 0, so that the design reference plane of the first segment 1 coincides with the measured reference plane;

[0085] Step S334: displaying the hidden display state of the second segment 2, and selecting two precision control points from the outer plate value point data of the second segment 2;

[0086] Step S335: implanting a reflector at two precision-controlled points on the outer plate of the second segment 2.

[0087] By rotating the design model of the first segment 1 90 degrees around the X-axis, and then moving the X-axis coordinate value, Y-axis coordinate value, and Z-axis coordinate value of the first reference point on the design model of the first segment 1 and the first reference point on the first segment 1 at the measured site to 0; when the design reference plane is overlapped with the measured reference plane, the design model of the first segment 1 can be overlapped with the measured model of the first segment 1. At this time, the display status of the second segment 2 is changed to display, and the coordinates of the two precision control points on the second segment 2 in the analysis software are the theoretical data for on-site positioning.

[0088] When the design model is rotated 90 degrees along the X-axis, the Y-axis coordinate value and the Z-axis coordinate value of the design model can be converted, so that the coordinate conversion of each precision control point in the design model corresponds one by one to the Y-axis coordinate and Z-axis coordinate of the measured coordinate axis of each precision control point on the first section 1 of the mounting site.

[0089] By moving one point and three points, the design reference plane on the design model of the first segment 1 can be made to coincide with the measured reference plane on the measured model, and the coordinate data of each precision control point on the design model coincide with the coordinate data of each precision control point on the measured model; at this time, by displaying the second segment 2 and selecting two precision control points on the outer plate value data of the second segment 2, the coordinate data of the two precision control points are the theoretical data for on-site positioning.

[0090] For example, see Figure 3In this embodiment, the coordinates of the precision control points on the design model of the first segment 1 after conversion are P1(0, 0, 0), P2(12561, 0, 0), P3(11964, 16038, 727), and P3(2632, 16581, 0); the two precision control points selected on the second segment 2 after conversion are Q1 and Q2, both of which are located at the bow end of the outer plate of the second segment 2, and the coordinate data of Q1 and Q2 are Q1(25073, -23, 1704) and Q2(21455, 15592, 2783), respectively. The theoretical data of on-site positioning of the two precision control points are: Q1(25073, -23, 1704), Q2(21455, 15592, 2783).

[0091] Wherein, step S4 comprises the following steps:

[0092] Step S41: transporting the second segment 2 to the loading site by a crane, adjusting the position of the second segment 2 along the length direction, width direction, and height direction, and roughly positioning the position of the second segment 2;

[0093] Step S42: Detecting actual coordinate data of multiple key points of the outer plate on the first segment 1 and two precision control points on the second segment 2 by using a total station;

[0094] Step S43: comparing the positions of the two precision control points on the second segment 2 in the total station to determine the deviation between the actual position of the second segment 2 in the mounting site and the preset installation position;

[0095] Step S44: Based on the deviation between the actual position of the second segment 2 in the loading site and the preset position, the position of the second segment 2 is adjusted along the length direction, the width direction and the height direction by a crane until the coordinate data of the two precision control points on the second segment 2 in the total station are the same as the coordinate data of the precision control points on the second segment 2 in the design model;

[0096] Step S45: piers for supporting the second section 2 are arranged on the steel piers for the general assembly, the hooks are loosened to release the second section 2, and the first section 1 and the second section 2 are effectively sealed.

[0097] During the installation of the second segment 2, since reflective sheets are provided on the two precision control points on the second segment 2, the measured coordinate values ​​of the two precision control points on the second segment 2 can be measured by the total station. After the measured coordinate values ​​of the two precision control points are imported into the total station, the three-point movement of the measured first segment 1 and the second segment 2 can be performed, and the coordinate values ​​of the two precision control points after the three-point movement can be compared with the theoretical data of on-site positioning. By comparing the coordinate values ​​of the two precision control points after the three-point movement with the theoretical data of on-site positioning, the deviation of the second segment 2 from the preset installation position can be obtained, which is convenient for the on-site operator to adjust the position of the second segment 2 along the length, width and height directions according to the deviation.

[0098] Wherein, step S42 includes the following steps:

[0099] Step S421: Detecting the coordinate data of the first key point, the second key point, the third key point and two precision control points at the site by using a total station;

[0100] Step S422: Select the first key point, the second key point and the third key point in the total station to move the three points, move the Z-axis coordinate values ​​of the first key point, the second key point and the third key point to 0, and obtain the actual coordinate data of the two precision control points on the second segment 2.

[0101] For example, in this embodiment, the theoretical data for on-site positioning are Q1 (25073, -23, 1704) and Q2 (21455, 15592, 2783). After the models of the first segment 1 and the second segment 2 are converted by the total station, the measured coordinate data of Q1 and Q2 can be compared with the theoretical data for on-site positioning respectively to determine the deviation between the second segment 2 and the preset installation position.

[0102] The implementation principle of a method for assembling large-line hyperbolic segments of a shuttle tanker in an embodiment of the present application is as follows: in the process of assembling segments into an overall assembly, an operator can retrieve the segment information of each segment from a cloud platform, and select the first segment 1 based on the site conditions of the loading site, the positions of each segment in the overall assembly, and the assembly order of each segment, and set a steel pier for the overall assembly at the loading site for carrying and supporting the overall assembly based on the outer plate type value data of the first segment 1; after the first segment 1 is loaded and installed on the steel pier for the overall assembly by a crane, the actual coordinate data of multiple outer plate key points on the first segment 1 can be detected by a total station; after the measured model and the design model of the first segment 1 are integrated in the analysis software, the on-site positioning theoretical data of two precision control points on the second segment 2 after the second segment 2 is installed at the loading site can be obtained. According to; when the crane transports the second section 2 to the loading site, the operator can use the total station to detect the effects of multiple key points of the outer plate and the two precision control points. By adjusting the models of the first section 1 and the second section 2 in the total station, the deviation between the measured coordinate values ​​of the two precision control points on the second section 2 and the theoretical data of on-site positioning can be grasped, which is convenient for relevant personnel to adjust the second section 2 along the length, width and height directions according to the deviation between the measured coordinate values ​​of the two precision control points and the theoretical data of on-site positioning, until the coordinate positions of the two precision control points on the second section 2 match the theoretical data of on-site positioning; after completing the placement and installation of the second section 2, the first section 1 and the second section 2 are effectively sealed, so that the loading and installation of the first section 1 and the second section 2 can be realized. Through the above-mentioned technical means, it is possible to avoid on-site operators from frequently traveling back and forth between the loading site and the office during the process of loading the second section 2, reduce the occurrence of on-site operators being injured due to frequent traveling back and forth between the loading site and the office, effectively save the time and effort required to adjust the position of the second section 2, improve the efficiency of assembly between the second section 2 and the first section 1, and shorten the construction period for assembling the sections into a general group.

[0105] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
