[0031] The specific embodiments of the application are described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the application, but are not used to limit the scope of the application.

[0032] A preferred embodiment of the hatch cover digital simulation installation method of the application is shown in Figures 1 to 9 The hatch cover digital simulation installation method comprises the following steps:

[0033] S1, after the completion of hatch cover manufacturing, the measurement control points of each outfitting part are determined based on the hatch cover, and the installation data of each outfitting part is collected by using a total station.

[0034] After the completion of hatch cover manufacturing, the outfitting parts on the hatch cover need to be assembled with the hatch cover as accessories. According to the number of outfitting parts and the precision control point of installation, the measurement technical requirements of each outfitting part can be formulated. The installation data of each outfitting part is collected by using a total station, which is the position of each outfitting part on the hatch cover, i.e. the assembly data relative to the hatch cover. After being collected by the total station, the data can be easily archived in electronic form.

[0035] After the completion of hatch cover manufacturing, each line on the hatch cover already exists, and the coordinate size between the measurement control points of each outfitting part on the hatch cover and the lines on the hatch cover can be measured to obtain the relevant installation data.

[0036] S2, after the formation of the ship cargo hold, the installation position points of each outfitting part are determined on the hatch coaming according to the theoretical installation position of the outfitting part, the installation position points correspond to the measurement control points, and the position data of each outfitting part is collected by using a total station.

[0037] Part of the outfitting on the hatch cover is to be assembled on the hatch coaming, the installation position points of the outfitting on the hatch coaming are determined, the position data of the outfitting is collected by the total station, the assembly position of each outfitting on the hatch coaming can be determined, and the position data is specifically the coordinate size of the installation position points relative to the hatch coaming. The installation position points correspond to the measurement control points, which can ensure the position assembly accuracy of the same outfitting on the hatch cover. In the embodiment, when the position data on the hatch coaming is measured, the flatness of the hatch coaming is measured, and the measurement points of the data of the hatch coaming need to be increased due to the small number of longitudinal hatch coaming outfitting.

[0038] S3, determining the closing measurement points of the hatch cover, and measuring the closing data of the closing measurement points.

[0039] As shown in Figure 9 , the hatch cover is usually two, and the two hatch covers form the entire hatch cover after closing. The closing measurement points are selected on the hatch cover to obtain the closing data, which can be used for modification in the digital simulation process to ensure the accuracy of the hatch cover after installation. In the embodiment, the closing data can be measured synchronously when the installation data on the hatch cover is measured in step S1 to improve the efficiency. In the embodiment, ten closing points on the hatch cover are selected, and the actual closing data of the hatch cover is recorded after measurement.

[0041] The precision analysis control software is used to splice the installation data and the ship coordinate system, and the precision between the installation data and the theoretical data of the closing points of the hatch cover in the ship coordinate system can be obtained by the precision analysis control software, so as to judge the closing precision and preliminarily ensure the installation accuracy of the outfitting on the hatch cover. In the embodiment, the precision analysis control software is specifically DACS software.

[0042] S5, applying the precision analysis control software to splice the position data of the installation position points in step S2 and the splicing data in step S4, and matching and adjusting the compression amount of the hatch cover.

[0043] The installation data of the hatch cover and the closing data of the hatch cover form the splicing data, and the position data on the hatch coaming obtained in step S2 is spliced and analyzed by the precision analysis control software on the basis of the data, so as to match and adjust the compression amount of the hatch cover, that is, the matching relationship between the hatch cover and the installation position on the hatch coaming after closing, and the precision of the hatch cover and the hatch coaming after adjustment meets the drawing and process requirements.

[0044] S6, adjust the coordinate system of each fitting on the hatch cover, from the hull coordinate system to the cargo hold coordinate system, and derive the fitting installation measurement table and the accessory adjustment pad measurement table.

[0045] In the application of the precision analysis control software in step S4, the fittings are data-fitted based on the hull coordinate system, while in the field construction, the coordinate system of the fittings and other accessories is based on the cargo hold, so the fitting installation measurement table and the accessory adjustment pad measurement table are derived from the hull coordinate system to the cargo hold coordinate system, which is convenient for subsequent field construction.

[0046] S7, according to the fitting installation measurement table and the accessory adjustment pad measurement table in step S6, carry out field installation work on the construction site.

[0047] Under the guidance of the fitting installation measurement table and the accessory adjustment pad measurement table, the field construction can quickly install each accessory and subsequent precision inspection and processing, etc., which improves the efficiency of field work.

[0048] The digital simulation installation method of the hatch cover, after the completion of the hatch cover, obtains the installation data and position data of the fittings according to the measurement control points of each fitting on the hatch cover and the installation position points of the fittings on the hatch coaming, carries out fitting analysis on the installation data, position data and fitting data of the hatch cover through the precision analysis control software, simulates the installation of the hatch cover, so that the fitting data precision, compression amount and other data of the hatch cover meet the requirements of the drawings, and then the related drawings are derived for field construction, which reduces the precision error caused by manual measurement, improves the installation precision and construction efficiency of the hatch cover, improves the construction environment of the hatch cover, reduces the risk coefficient and cross operation.

[0049] Preferably, in step S1, the outfitting parts include hatch cover positioning pins, guide devices or binding bridges, hatch cover transverse limiting devices, hatch cover stop devices, support block adjusting pads, pressing flat irons, separation joint pressing plates, the measurement control points of the hatch cover positioning pins include at least four points on the edges of the pin holes, and the center of the pin hole is determined by the four points; the installation data of the guide devices or the binding bridges include the coordinates of the installation surface of the adjusting pads of the guide devices or the binding bridges; the installation data of the hatch cover transverse limiting devices include the installation position of the adjusting pads of the bevels, four points are selected on each surface of the adjusting pads of the bevels, and the height and position of each point are measured; the measurement control points of the hatch cover stop devices include the measurement points on the upper surface of the stop ear plates and the intersection points of the center lines of the stop ear plates and the horizontal lines of the rubber grooves, and the installation data of the hatch cover stop devices include the height value of the upper surface of the stop ear plates, the height value of the rubber groove of the hatch cover stop device, and the installation center point of the stop ear plates; the installation data of the support block adjusting pads include the flatness of the four corners of the support block installation seat plates, the rubber groove values, and the center values of the support block installation seat plates; the installation data of the pressing flat irons include the corresponding positions, the flatness of the hatch cover rubber groove, and the flatness of the corresponding positions of the hatch coaming; and the installation data of the separation joint pressing plates include three-dimensional coordinates, center line positions, and angle values.

[0050] The installation data of different outfitting parts on the hatch cover are different when the outfitting parts are installed, and different measurement control points can be selected to collect relevant installation data according to the corresponding installation data requirements.

[0051] Specifically, when the hatch cover positioning pins are installed, the installation data requirements are Fx and Fy, at least four points on the edges of the pin holes on the hatch cover are measured, the center of the pin hole can be found by the principle of the perpendicular line of the four points, and the installation data of the hatch cover positioning pins can be obtained according to the coordinates of the center. When measuring, the four points on the pin hole are as close to the diameter as possible to form two points, and the four points are evenly distributed on the circumference of the pin hole to reduce the measurement error.

[0052] As shown in FIG. 1, Figure 2 When the guide devices or the binding bridges are installed, the installation data requirements are Fx and Fy, the coordinates of the installation surface of the adjusting pads of the binding bridges or the guide devices are measured, the installation position of the adjusting pads can be obtained, and the installation position of the guide devices or the binding bridges can be determined. Since the hatch cover has been made, the reference points on the hatch cover already exist, the values of the same positions above the adjusting pads of the binding bridges or the guide devices are simulated after being subtracted by a tolerance of 13 mm, and the thickness of the adjusting pads that need to be installed is obtained, and the height measurement of the installation position of the adjusting pads is required.

[0053] As shown in FIG. 1, Figure 3 and Figure 4As shown, the installation data of the hatch cover transverse limiting device requires Fx and Fy, and the installation position data of the accessory bevel adjusting pad needs to be measured. Four points are selected on each surface of the bevel adjusting pad, and the height and position of each point are measured to ensure that the height and position are basically consistent. Since the hatch cover accessory and the hatch cover body are both in the form of a bevel groove, the height direction is based on the edge of the bevel groove of the accessory, which can improve the accuracy. In this embodiment, attention should be paid to the reverse structure of the accessory and the cargo hold forming size during installation of the hatch cover transverse limiting device. When there is a large deviation in the cargo hold forming, the installation size error of the positioning pin needs to be adjusted, which is achieved by adjusting the thickness of the upper plate.

[0054] As shown, Figure 5 With Figure 6 As shown, the installation of the hatch cover stop device requires Fx, Fy and Fz data. The height value of the upper surface of the stop ear plate, the height value of the rubber groove of the hatch cover stop device, and the installation center point of the stop ear plate can be obtained by collecting the position of the intersection point of the upper surface measurement point of the stop ear plate and the center line of the rubber groove. In this embodiment, the upper surface measurement point of the center line of the stop ear plate and the center line point need to be used multiple times, and attention should be paid to the integrity of the measurement to prevent omission. The reflector needs to be placed in the appropriate position during measurement.

[0055] As shown, Figure 8 The installation of the support block adjusting pad requires Fx, Fy and Fz, and the installation data of the support block adjusting pad can be obtained by collecting the Fx, Fy and Fz values of the four corner flatness, rubber groove value and center value of the support block mounting seat plate. In this embodiment, the measurement points need to be complete, and the positions measured correspond one by one to the point positions measured by the hatch coaming.

[0056] As shown, Figure 7 The installation of the pressing flat iron requires Fx, Fy and Fz, i.e. its three-dimensional coordinates. The pressing flat iron is used to press various accessories, and the corresponding position is the installation position of each accessory. The installation coordinates of the pressing flat iron can be obtained by collecting the coordinates of the corresponding position. The installation height of the pressing flat iron is determined by digital simulation. In this embodiment, the number of measurement points of the pressing flat iron in the longitudinal direction of the ship should be sufficient to improve the accuracy and data integrity of the simulation installation.

[0057] The installation data of the separation wind pressing plate needs to be measured after the hatch cover is formed. The sample plate is made and installed according to the measured model.

[0058] Preferably, the installation data measurement of the guide position or the binding bridge is performed after the hatch cover is welded, and the installation data measurement of the hatch cover transverse limiting device is performed after the hatch cover transverse limiting device is installed.

[0059] The installation data measurement of the guide position or the binding bridge is measured after the welding of the hatch cover is completed, and the installation data measurement of the hatch cover transverse limiting device is measured after the installation of the hatch cover transverse limiting device, so that the measurement precision caused by welding deformation can be avoided.

[0060] Preferably, the installation data measurement of the separation joint pressing plate is measured after the hatch cover is closed.

[0061] The installation data of the separation joint pressing plate is measured after the hatch cover is closed, so that the error caused by the adjustment of the closed hatch cover can be reduced, and the precision of the data can be improved.

[0062] Preferably, in step S2, the installation positions of various fittings are drawn on the hatch coaming, the installation position points are selected on the installation positions, and the flatness of the installation positions of various fittings around the hatch coaming is measured.

[0063] The flatness of the installation positions of various fittings around the hatch coaming is measured, so that the angle during the installation of the fittings can be simulated, and the digital simulation installation precision of the fittings can be improved. Since there are fewer longitudinal hatch coaming fittings, the number of installation position points of the hatch coaming is increased, and the installation position points and the measurement control points of various fittings of the hatch cover are corresponded as much as possible in the transverse and longitudinal directions.

[0064] Preferably, in step S4, when the precision analysis control software checks the precision of the spliced data, the closing precision is ensured to be within 2 mm, and when the closing data of the closing measurement points of the hatch cover exceeds the range, the closing data of the closing measurement points is manually adjusted.

[0065] When the closing precision exceeds 2 mm, the closing data of the hatch cover during the closing is manually adjusted in the precision analysis control software, so that the closing data matches the theoretical data, and the closing data precision is within 2 mm, so that the installation data of various fittings on the hatch cover in step S1 can be accurately determined.

[0066] Preferably, in step S5, when the closing data of the hatch cover is matched and adjusted, three points of the hatch cover rubber groove plane data and the hatch coaming plane data are determined to determine a plane, and the adjusted plane meets the assembly precision requirement.

[0067] After the hatch cover is spliced and closed, the closing data of the hatch cover is simulated and installed with the hatch coaming, the rubber groove plane of the hatch cover is in contact with the hatch coaming plane, and the precision can be ensured to meet the drawing and process requirements by adjusting the two planes to match.

[0068] Preferably, in step S5, when the matched and adjusted closing data of the hatch cover does not meet the requirement, the data of the hatch cover is separately adjusted, the hatch cover is made into an inclined surface, the inclination of the hatch cover is controlled to be less than 3 degrees, and the adjustment ensures that the hatch cover meets the required tolerance range.

[0069] When the hatch coaming plane deviation of the whole cargo hold is large, the data of the whole hatch cover is split into single block hatch cover data for angle adjustment, and after the adjustment, all the numbers of the hatch cover can be ensured to meet the tolerance range required by the drawing, and in general, the tolerance range is ±6mm.

[0070] Preferably, in step S7, the field installation operation includes: installing the hatch cover accessories according to the accessory installation measurement table, installing and welding the hatch cover and the hatch coaming accessories according to the accessory installation measurement table, and performing post-welding inspection work, hatch coaming and hatch cover finishing painting operation, hatch cover on board, hatch cover accessory installation precision inspection and processing, and hatch cover utility and hatch cover tightness finishing inspection.

[0071] In summary, the embodiment of the present application provides a kind of digital simulation installation method of hatch cover, after the hatch cover is finished, according to the measurement control point of each accessory on the hatch cover and the installation position point of the accessory on the hatch coaming, the installation data and position data of the accessory are obtained using total station, the closing data of the hatch cover is analyzed by precision analysis control software to the installation data, position data and closing data, the installation of hatch cover is simulated, so that the closing data precision, compression amount and other data of hatch cover meet the drawing requirements, then export related drawings for field construction, reduce the precision error caused by manual measurement, improve the installation precision and construction efficiency of hatch cover, improve the construction environment of hatch cover, reduce the risk coefficient and cross operation.

[0072] The above only describes the preferred embodiments of the present application, and it should be noted that for ordinary skilled in the art, without departing from the technical principles of the present application, several improvements and replacements can be made, and these improvements and replacements should be considered as the protection scope of the present application.
