Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a method and device for assembling half a ship remotely. Background Art

[0002] At present, the block construction method is one of the most effective ways to achieve efficient construction of general assembly. With the continuous improvement of hoisting and transportation capabilities, the trend of giant blocks is becoming more and more obvious. As a result, multiple blocks are built in parallel at different locations, and then moved to the same slipway for assembly, which can shorten the construction period, improve site utilization, make the assembly production line schedule more flexible, and effectively improve the production capacity of the general assembly plant, but at the same time put forward higher requirements on the accuracy of the construction of half ships at different locations.

[0003] The current method of closing half of the ship has no unified standard, which causes the closing mouth of the half ship to be misaligned and unable to be accurately positioned, resulting in poor closing effect and the need for a second start of transportation, which increases the transportation cost. Summary of the invention

[0004] The present invention provides a method and device for remote half-ship closure, which realizes full-process precision monitoring and improves the precision of half-ship closure while ensuring the closure efficiency.

[0032] Furthermore, based on the closure end face data, closure simulations are performed on each half ship to be closured in pairs in turn to obtain closure simulation results, specifically:

[0033] Determine a plurality of measuring points in the closing end surface data of each half ship to be closed; wherein the plurality of measuring points are respectively distributed on the ship length reference line, the ship width reference line and the molded depth reference line;

[0037] Furthermore, the method of determining a plurality of measurement points in the closing end surface data of each half-ship to be closed is specifically as follows:

[0049] When the simulated corrected secondary structures have no impact on the primary structure, each secondary structure is corrected according to the margin to be corrected.

[0050] Furthermore, a guide stop base is arranged on each half-ship to be closed according to the closing gap, and the reference half-ship is used as a positioning reference, and a traction device is used to close each half-ship to be closed toward the reference half-ship, specifically:

[0051] Select a guide stop base of corresponding size according to the closing gap, and install the guide stop base on the closing end surface of each half ship to be closed;

[0052] Taking the reference half-ship as the positioning reference, the half-ships to be closed are closed toward the reference half-ship by using the traction device.

[0053] Furthermore, the reference half-ship is used as a positioning reference, and each half-ship to be closed is closed toward the reference half-ship by using a traction device, specifically:

[0078] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0079] Example 1

[0080] See also Figure 1 , is a flow chart of an embodiment of a remote half-ship assembling method provided by the present invention, the method comprises steps 101 to 107, each step is specifically as follows:

[0081] Step 101: Determine a reference half-ship among a plurality of half-ships to be assembled.

[0082] In the first embodiment of the present invention, during the ship construction process, due to the characteristics of large weight and large size of the ship, the ship is generally built in sections. After each half ship is built on its own slipway, the half ship is assembled using the block construction method. One of the multiple half ships is a reference half ship, and the reference half ship is used as a positioning reference. The remaining half ships can be assembled and docked with the reference half ship by transfer. The present invention determines a reference half ship, thereby determining the assembling reference, which can greatly improve the accuracy of the assembling of the half ships.

[0083] Step 102: Acquire the closing end surface data of each half ship to be closed.

[0084] Further, in the first embodiment of the present invention, the closing end face data of each half ship to be closed is obtained, specifically:

[0085] Measure the 3D data of several half-ships to be assembled;

[0086] Constructing a three-dimensional coordinate system of each half-ship to be assembled based on the three-dimensional data of each half-ship to be assembled;

[0087] Acquire the closing end surface data of each half ship to be closed in the three-dimensional coordinate system of each half ship to be closed;

[0088] Among them, the three-dimensional coordinate systems of all the half-ships to be assembled are established in the same precision measurement and control network.

[0089] In the first embodiment of the present invention, before the half-ship is closed, the closing of each half-ship to be closed is simulated, and the parameters of each half-ship are adjusted according to the simulation effect to achieve a closing effect with higher precision. When performing the closing simulation, it is necessary to first obtain the closing end surface data of each half-ship to be closed, and use a computer algorithm to perform the closing simulation. Among them, in order to achieve a better simulation effect, the closing end surface data used for simulation is three-dimensional data, which is obtained by actually measuring the half-ship to be closed. Specifically, the relevant three-dimensional data of the half-ship to be closed and its corresponding ship moving carrier are actually measured by measuring equipment. The hull coordinate system is obtained from the drawings of each half-ship to be closed, and the three-dimensional coordinate system of each half-ship to be closed is respectively constructed based on the measured three-dimensional data and the hull coordinate system. The three-dimensional coordinate system contains all the three-dimensional data of the half-ship to be closed and its corresponding ship moving carrier. The present invention establishes the three-dimensional data of different half-ships to be closed in the same precision measurement and control network, so that the positioning reference lines of different half-ships to be closed built in different places are consistent, thereby ensuring the accurate positioning of the closing of the half-ship.

[0090] Furthermore, in the first embodiment of the present invention, the three-dimensional data of several half-ships to be folded are measured, specifically:

[0091] Measuring the hull parameters of several half-ships to be assembled; the hull parameters include the hull centerline, the overall section carrying rib inspection line, the half-ship port side longitudinal section line and the half-ship starboard side longitudinal section line;

[0092] Measure the ship moving carrier parameters corresponding to several half ships to be folded; the ship moving carrier parameters include the slipway center line, the track center line and the track inspection line.

[0093] In the first embodiment of the present invention, the three-dimensional coordinate system of the half-ship to be assembled is constructed to mainly measure the hull centerline, the overall section loading rib inspection line, the half-ship port side longitudinal section line and the half-ship starboard side longitudinal section line of the half-ship to be assembled; when the construction of the half-ship is completed, the half-ship to be assembled is generally moved by track; therefore, the ship moving carrier parameters corresponding to the half-ship to be assembled generally include the slipway centerline, the track centerline and the track inspection line.

[0094] Furthermore, in the first embodiment of the present invention, before analyzing the flatness of the folding end surface of each half-ship to be folded based on the folding end surface data, the method further includes:

[0095] Obtaining position parameters of the reference half-ship and position parameters of the reference carrier in the three-dimensional coordinate system of the reference half-ship, and generating a relative size relationship;

[0096] The half-ship position and the carrier position of each half-ship to be closed are adjusted according to the relative size relationship, and the adjusted half-ship position parameters and the carrier position parameters are obtained to update the corresponding three-dimensional coordinate system of the half-ship to be closed.

[0097] In the first embodiment of the present invention, before the half-ship to be closed is closed and moved, the relative position of each half-ship to be closed and its corresponding ship moving carrier is controlled to be consistent, which can ensure that the accuracy requirements of each half-ship to be closed are consistent, thereby improving the accuracy of the half-ship closing. Specifically, the measured position parameters of the reference half-ship and the position parameters of the reference carrier are first obtained from the three-dimensional coordinate system of the reference half-ship, and the three-dimensional position relationship between the reference half-ship and the reference carrier is analyzed, and based on this, the carrier positions of the remaining half-ships to be closed are adjusted.

[0098] Further, in the first embodiment of the present invention, the position parameters of the reference half-ship and the position parameters of the reference carrier are obtained in the three-dimensional coordinate system of the reference half-ship to generate a relative size relationship, specifically:

[0099] Obtaining the hull centerline and the slipway centerline of the reference half ship in the three-dimensional coordinate system of the reference half ship;

[0100] The three-dimensional relative positions of the hull centerline and the slipway centerline of the reference half ship are analyzed to generate relative size relationships.

[0101] In the first embodiment of the present invention, by analyzing the three-dimensional positional relationship between the hull centerline of the reference half-ship and the centerline of the slipway, a relative size relationship as a reference can be obtained. The hull centerline and the slipway centerline can clearly illustrate the positional relationship between the reference half-ship and the center of the reference carrier, so a more accurate reference relative relationship can be obtained by analyzing these two parameters.

[0102] Further, in the first embodiment of the present invention, the half-ship position and the carrier position of each half-ship to be folded are adjusted according to the relative size relationship, and the adjusted half-ship position parameters and the carrier position parameters are obtained, and the corresponding three-dimensional coordinate system of the half-ship to be folded is updated, specifically:

[0103] For each half ship to be assembled except the reference half ship, obtain the hull centerline and the slipway centerline in the three-dimensional coordinate system respectively;

[0104] Analyze the three-dimensional relative positions of the hull centerline and the slipway centerline respectively;

[0105] comparing the three-dimensional relative position with the relative size relationship;

[0106] When the three-dimensional relative position is inconsistent with the relative size relationship, the position of the ship moving carrier is adjusted based on the center line of the hull;

[0107] When the position of the ship moving carrier is adjusted, the ship moving carrier parameters are reacquired, and the corresponding three-dimensional coordinate system of the half ship to be folded is updated according to the ship moving carrier parameters.

[0108] In the first embodiment of the present invention, the relative size relationship between the reference half-ship and the reference carrier is used as a template, and the spacing between the remaining groups of half-ships to be closed and their corresponding moving ship carriers is measured respectively, and the measured spacing is compared with the relative size relationship used as the template. At this time, a suitable deviation threshold can be set. If the spacing data of the half-ship to be closed exceeds the deviation threshold, it is necessary to adjust the position of the moving ship carrier corresponding to the half-ship to be closed so that the spacing data is within the deviation threshold. The present invention keeps the spacing between all the half-ships to be closed and their corresponding moving ship carriers consistent by setting the relative size relationship as a template, reduces the precision error after closing before the half-ships are closed, and thus improves the closing accuracy.

[0109] Step 103: Based on the closing end face data, the closing simulation is performed on each half ship to be closed in pairs in turn to obtain a closing simulation result.

[0110] Further, in the first embodiment of the present invention, based on the closure end face data, closure simulation is performed on each half ship to be closured in pairs in turn to obtain closure simulation results, specifically:

[0111] Determine a plurality of measuring points in the closing end surface data of each half ship to be closed; wherein the plurality of measuring points are respectively distributed on the ship length reference line, the ship width reference line and the molded depth reference line;

[0112] The two halves of the ship to be closed are simulated for closing in pairs, and the structural misalignment deviation after the simulated closing is analyzed by comparing several measurement points on the two halves of the ship to be closed;

[0113] According to several measuring points on the ship length reference line, the end surface flatness analysis is carried out on the end surface of each half ship to be assembled, and the end surface pre-repair amount is obtained;

[0114] Based on the structural misalignment deviation and the end face pre-repair amount, the allowance to be corrected and the closing gap are determined to generate a closing simulation result; wherein the allowance to be corrected includes the allowance to be corrected in the ship length direction, the allowance to be corrected in the ship width direction and the allowance to be corrected in the depth direction.

[0115] In the first embodiment of the present invention, before the half-ship is folded and moved, based on the folding end surface accuracy data obtained in the three-dimensional coordinate system, a folding simulation can be performed on each half-ship to be folded, and the baseline correction values ​​in the three directions of ship length, ship width and draft can be obtained, thereby minimizing the structures that need to be adjusted before folding and improving the folding efficiency.

[0116] In the first embodiment of the present invention, the closure end face data obtained in the three-dimensional coordinate system include but are not limited to the closure end face outer plate profile and the main longitudinal continuous wall plate, and the measurement data on each layer of the platform plate (inner bottom plate, middle deck, main deck). By comparing the measurement points on the half-ship to be closed, the current closure end face situation can be analyzed. The measurement point data obtained in the three-dimensional coordinate system are all spatial three-dimensional coordinates. By comparing the model theoretical value with the actual measured point, the deviation between the actual measured three-dimensional coordinate and the theoretical coordinate can be obtained for each measurement point, so as to judge, analyze and adjust the end face accuracy data. Since the theoretical data of the two closure end face measurement points are the same when they are consistent, the theoretical data should also be the same. Therefore, by comparing the two closure end face data, the structural alignment and misalignment deviation after closure can be pre-judged and analyzed before the half-ship is closed. At the same time, according to the measurement point data in the length direction of the closure end face, the flatness of the closure end face can be analyzed to obtain the trimming amount of the closure section. Therefore, after analyzing the misalignment deviation of the structure and the amount of trimming of the closing section, the closing simulation results can be generated, providing a theoretical basis for the half-ship trimming.

[0117] Furthermore, in the first embodiment of the present invention, a number of measurement points are determined in the folding end surface data of each half-ship to be folded, specifically:

[0118] Acquire the data corresponding to a plurality of preset hull structures that must be measured from the closure end surface data of each half ship to be closured;

[0119] Selecting a number of required measurement points from the data corresponding to each required-measurement hull structure;

[0120] Interpolating among the plurality of required measurement points, and selecting a plurality of optional measurement points;

[0121] Several mandatory measuring points and several optional measuring points are determined as the measuring points of the half ship to be assembled.

[0122] Furthermore, in the first embodiment of the present invention, the hull structure that must be measured includes the hull centerline, the section carrying rib inspection line, the half-ship port side longitudinal section line, the half-ship starboard side longitudinal section line, the sub-section waterline reference line and the closed end face outer plate contour.

[0123] In the first embodiment of the present invention, when performing the closing simulation, the measurement points selected on the half ship to be closed are divided into mandatory measurement points and optional measurement points. The mandatory measurement points are points on the main structure of the half ship to be closed, such as the centerline of the hull, the waterline baseline of the sub-section, the longitudinal section baseline, the points where important and main structures are located, and the line type change (turning) points. The measurement points are selected according to the number and distribution of the measurement points, and the distance threshold between the measurement points is set. Multiple selected measurement points are selected on non-important structures, and the distance between each selected measurement point does not exceed the preset distance threshold.

[0124] Step 104: Determine the margin to be corrected and the closing gap based on the closing simulation result.

[0125] Step 105: Correct the structure of each half-ship to be assembled according to the margin to be corrected.

[0126] Furthermore, in the first embodiment of the present invention, the structure of each half-ship to be assembled is corrected according to the margin to be corrected, specifically:

[0127] Determining a number of structures to be corrected in the remaining amount to be corrected;

[0128] Determine the importance of each structure to be revised;

[0129] Through importance analysis, several structures to be revised are classified into several main structures and several secondary structures;

[0130] Modify each main structure according to the margin to be modified;

[0131] Perform simulation correction on each secondary structure according to the margin to be corrected, and analyze whether the secondary structure after simulation correction has any impact on the primary structure;

[0132] When the simulated corrected secondary structures have no impact on the primary structure, each secondary structure is corrected according to the margin to be corrected.

[0133] In the first embodiment of the present invention, after the allowances to be corrected in the three directions of ship length, ship width and draft are obtained through simulation analysis, the alignment of the main structure is prioritized according to the importance and secondary nature of the structure to be corrected, and a reasonable correction plan is obtained. For example, the main structure includes the outer plate contour, longitudinal wall, and platform plates of each layer. If the allowance to be corrected involves the main structure, the main structure is trimmed first to ensure the correct alignment of the main structure. If the allowance to be corrected involves the secondary structure, it is necessary to determine whether the trimming of the secondary structure will affect the alignment of the main structure. If it does not affect, the secondary structure can be directly corrected. If it does affect, the secondary structure needs to be adjusted while ensuring the alignment of the main structure.

[0134] In the first embodiment of the present invention, each secondary structure is simulated and corrected according to the margin to be corrected, and it can be analyzed whether the secondary structure after the simulation correction has an impact on the main structure. For example, if after the simulation correction of the secondary structure, it is found that it will have an adverse effect on the main dimensions of the hull structure, such as affecting the width, depth, layer height, etc., then it is considered that the repair of the secondary structure has affected the main structure; or, if after the simulation correction of the secondary structure, it is found that it will cause a dislocation effect on the base alignment reinforcement structure, then it is considered that the repair of the secondary structure has affected the main structure; or, if after the simulation correction of the secondary structure, it is found that it affects the closing and docking of the outfitting parts, such as the closing and docking flange pipe, etc., then it is also considered that the repair of the secondary structure has affected the main structure. Therefore, after the simulation correction of each secondary structure, it can be concluded whether the repair of the secondary structure affects the main structure, so as to decide whether to repair the secondary structure.

[0135] Step 106: a guide stop base is arranged on each half-ship to be closed according to the closing gap, and the reference half-ship is used as a positioning reference, and each half-ship to be closed is closed toward the reference half-ship by a traction device.

[0136] Further, in the first embodiment of the present invention, a guide stop base is arranged on each half-ship to be closed according to the closing gap, and the reference half-ship is used as a positioning reference, and a traction device is used to close each half-ship to be closed toward the reference half-ship, specifically:

[0137] Select a guide stop base of corresponding size according to the closing gap, and install the guide stop base on the closing end surface of each half ship to be closed;

[0138] Taking the reference half-ship as the positioning reference, the half-ships to be closed are closed toward the reference half-ship by using the traction device.

[0139] In the first embodiment of the present invention, the gap between the butt joints of the closing end surface can be obtained according to the closing simulation results, so a guide stop base of a suitable size is selected according to the gap, and the guide stop base is installed at a suitable position of the closing end surface according to the simulation results. After the installation of the guide stop base is completed, the traction device is used to close each half ship to be closed toward the reference half ship.

[0140] Further, in the first embodiment of the present invention, the reference half-ship is used as the positioning reference, and the traction device is used to close each half-ship to be closed toward the reference half-ship, specifically:

[0141] In the process of closing each half-ship to be closed toward the reference half-ship by using the traction device, the offset position relationship between the reference half-ship and the reference carrier is monitored, as well as the offset position relationship between each half-ship to be closed and the corresponding ship moving carrier is monitored, and the offset position relationship between each half-ship to be closed and the corresponding ship moving carrier is controlled to be consistent with the offset position relationship between the reference half-ship and the reference carrier.

[0142] Further, in the first embodiment of the present invention, the offset position relationship between the reference half-ship and the reference carrier is monitored, specifically:

[0143] Monitor the offset position relationship between the berth centerline of the reference half ship and the hull centerline of the reference carrier;

[0144] Monitoring the offset position relationship between the half-ship port longitudinal section line of the reference half-ship and the hull centerline of the reference carrier;

[0145] Monitor the offset position relationship between the half-ship starboard longitudinal section line of the reference half-ship and the hull centerline of the reference carrier.

[0146] In the first embodiment of the present invention, during the process of closing the half-ships, in order to ensure the closing accuracy, the relative position between the half-ship to be closed and its corresponding ship moving carrier is monitored in real time, and controlled to be consistent with the relative position between the reference half-ship and the reference carrier. Specifically, the left and right deviations between the center line of the slipway of the reference half-ship, the longitudinal section line of the port side of the half-ship and the longitudinal section line of the starboard side of the half-ship and the hull center line of the reference carrier are monitored respectively, and the monitoring data of the reference half-ship is used as a template. At the same time, the left and right deviations between the center line of the slipway of the remaining half-ships to be closed, the longitudinal section line of the port side of the half-ship and the longitudinal section line of the starboard side of the half-ship and the hull center line of the corresponding ship moving carrier are monitored. The left and right deviations between the center line of the slipway of the half-ship to be closed, the longitudinal section line of the port side of the half-ship and the longitudinal section line of the starboard side of the half-ship and the hull center line of the corresponding ship moving carrier are controlled to be consistent with the template data measured on the reference half-ship, so that all the half-ships to be closed can move to the left or right at the same time, or remain unchanged at the same time. The present invention monitors the offset position relationship between each half-ship to be closed and its corresponding ship moving carrier in real time during the closing process, which can avoid human errors, avoid measurement blind spots, and improve the closing accuracy during the closing process.

[0147] Step 107: During the closing process, the closing accuracy is determined by using the guide stop base. When the closing accuracy meets the preset accuracy requirement, it is determined that the closing of the half-ship is completed.

[0148] Further, in the first embodiment of the present invention, the guide stop base is used to judge the closing accuracy during the closing process, and when the closing accuracy meets the preset accuracy requirement, it is determined that the closing of the half-ship is completed, specifically:

[0149] During the closing process, the closing accuracy is determined based on the distance between the guide stop bases;

[0150] When the two guide stop bases are fitted together, it is determined that the current closing accuracy meets the preset accuracy requirement, and it is determined that the closing of the half-ship is completed.

[0151] In the first embodiment of the present invention, see Figure 2 , is a structural schematic diagram of an embodiment of the guide stop base provided by the present invention. According to the simulation analysis results, a group of guide stop bases can be set on the left and right exteriors of the closing end faces of each half-ship to be closed. When the guide stop bases of the two half-ships are in contact and fit with each other, it means that the gap between the two closing surfaces reaches the expected result of the simulation analysis. At this time, the gap between the closing end faces meets the welding requirements, and the closing movement is controlled to end. The present invention can prevent the half-ship from stopping too early or too late during the closing movement process by installing a guide stop base on the closing end face, avoiding a large gap caused by stopping too early, thereby starting the movement again and increasing the movement cost; it also avoids collision of the half-ship structure caused by stopping too late.

[0152] In summary, the first embodiment of the present invention provides a method for assembling half-ships in different locations, in which the three-dimensional data of different half-ships to be assembled are established in the same precision measurement and control network, so that the positioning reference lines of different half-ships to be assembled in different locations are kept consistent, reducing the precision error after assembling; before assembling the half-ship, the reference half-ship is determined, and the relative position relationship between each half-ship to be assembled and its corresponding ship-moving carrier is controlled to be consistent, avoiding the situation where the half-ship to be assembled is offset due to transportation and causes the overall misalignment of the half-ship assembling; before assembling the half-ship, a assembling simulation is performed, and each half-ship to be assembled is corrected according to the simulation results to ensure that the hull structure alignment and the weld gap meet the relevant precision requirements; when assembling the half-ship, the offset position relationship between the reference half-ship and other half-ships to be assembled is controlled in real time to be consistent, ensuring the alignment of the half-ship structure during the assembling process. The present invention realizes the whole process precision monitoring, improves the precision of half-ship assembling under the premise of ensuring the assembling efficiency, and ensures that the precision of the half-ship in the off-site construction process and the overall precision of the whole ship after the half-ship is assembled meet the relevant requirements of the shipbuilding quality standards.
