Description

Technical Field

[0001] The present application relates to the technical field of container ship manufacturing, and in particular to a method for installing a space-limiting outfitting part of a ship container and an installation data calculation system. Background Art

[0002] The common sizes of ship containers are 20 feet and 40 feet. In order to fix the containers at the bottom of the inner cabin of the container ship, multiple container loading positions are set on the bottom deck of the ship. One container loading position can be installed with a 40-foot container or two 20-foot containers side by side. In order to fix the bottom layer of containers on the bottom deck of the ship, vertical guide rails are set at the four corners of the container loading position to limit the vertical side of the container. At the same time, the four corners of the container loading position and the middle of the two long sides are provided with box foot belly plates to adapt to 20-foot and 40-foot containers. In addition, in order to better fix the containers, some limit outfitting parts are also used to limit and level the loaded 20-foot and 40-foot containers.

[0003] The position-limiting outfitting includes a bottom cone, a guide block and an adjustment plate. The adjustment plates for leveling are installed on the belly plates of the box feet at the four corners of the container loading position, and the bottom cone is installed on the adjustment plates at the four corners. In addition, if two 20-foot containers are installed side by side, a guide block along the long side direction is installed on the belly plates of the box feet in the middle of the container loading position to limit the slippage of the 20-foot container. And an adjustment plate for leveling is also installed on the belly plates of the box feet in the middle corresponding to the corners of the adjacent sides of the two 20-foot containers. Through the combined action of the guide rails, adjustment plates, bottom cones and guide blocks, each container loading position can stably load 20-foot or 40-foot containers.

[0004] The bottom cone of a container ship is a conical component installed at the bottom of the cargo hold of a container ship. Its main function is to limit the movement of containers in the hold and prevent the containers from being displaced or tipped over during transportation. One of the key factors that has always restricted the undocking status and terminal cycle of container ships, especially ultra-large container ships, is the cargo hold test container, which occupies a large amount of crane resources and restricts the construction of hatch covers, cargo holds and coating. The installation accuracy of the bottom cone is the main factor affecting the smooth inspection of the test container. In the past, the company's container ship bottom cone installation has always adopted the traditional installation process, resulting in the inspection of the bottom cone, guide rails, and adjustment plates needing to be verified through the test box, which greatly affects the overall construction speed of the container ship and becomes an important factor restricting the dock and terminal cycle. Summary of the invention

[0137] It should be noted that, for the guide block, it can be used together with the bottom cone and the adjustment plate to perform the primary simulation test box and the calibration simulation test box, or the guide block can be adjusted separately. In order to further explain the technical solution of the present application, the present application, in conjunction with the accompanying drawings, provides a more detailed description of the technical solution of simultaneously performing the test box including the bottom cone, the adjustment plate and the guide block.

[0138] like Figures 3 to 15 As shown, in the container ship of the embodiment of the present application, the limiting outfitting includes a bottom cone 20, an adjustment plate 30 for leveling the container, and a guide block 40; a loading position is set on the bottom deck of the inner cabin, and vertical guide rails 50 are respectively set at its four corners, and a box foot web 10 is set at the four corners of the loading position and in the middle of its two long sides. Adjustment plates 30 corresponding to the container feet are installed on the box foot web 10, so as to be suitable for leveling 40-foot and 20-foot containers. The bottom cone 20 is installed on the adjustment plate 30 at the four corners of the loading position to cooperate and fix with the container feet. The guide block 40 is set on the box foot web 10 in the middle of the two long sides of the loading position along the bow and stern direction of the ship, and is used to limit the slippage of one end of the 20-inch container.

[0139] The corresponding installation method of the ship container limit outfitting parts is as follows:

[0140] Step 1: Figure 5 and Figure 6 As shown in the figure, after the guide rails 50 at the four corners of the loading position are installed, the bottom cone position lines 21 are drawn on the box foot webs 10 at the four corners to mark the bottom cone simulation position. The bottom cone position line 21 can be drawn with a cross line by chalking and punching. The punch is generally required to have 5 points, which are respectively at the near end of the cross line and the intersection of the cross line. Figure 7 As shown, the approximate center position of the adjustment plate 40 can be indicated by drawing a contour line or marking, so as to identify the simulated position of the adjustment plate. Figure 7 As shown, the guide block 40 is spot welded on the middle box foot web 10 according to the design dimensions.

[0141] It should be noted that Figure 6 The bottom cone simulation positions on both sides are marked on the box foot web 10, and Figure 7 The installation area of ​​the adjustment plate 30 is reserved on both sides of the guide block 40 on the middle container foot web 10 because adjacent container loading positions share the container foot web 10. In this embodiment, only the installation of the restricted outfitting parts on the same loading position needs to be considered.

[0142] Step 2: Establish coordinate points of the simulated test box at least at the bottom cone simulation position, the adjustment plate simulation position, the guide block, and the guide rail, obtain coordinate data of each coordinate, and establish an initial coordinate data set.

[0143] Specifically, Figure 6As shown, at the bottom cone simulation position, the center of the bottom cone position line 21 is used as the simulation test box coordinate point of the bottom cone, and the reflection sheet 101 is prevented here to facilitate data acquisition. Four bottom cones are set with a total of 4 measurement points, namely Figure 4 and Figure 5 Since the bottom cone simulation coordinate points have been set on the box foot web 10 at the four corners, it is equivalent to setting the adjustment plate simulation coordinate points here.

[0144] like Figure 7 As shown, a guide block simulation coordinate point is set on a side wall of the guide block 40 facing the loading position, and two guide blocks 40 correspond to two measurement points, namely Figure 4 and Figure 5 P17 and P18 in the figure. The foot web 10 inside the guide block 40 is provided with a simulated position of an adjustment plate corresponding to the foot of a 20-foot container. The center thereof can be used as a measuring point, and a reflector can be placed there. Four adjustment plates 40 in the middle need to be provided, namely Figure 4 and Figure 5 P13, P14, P15 and P16 in.

[0145] like Figure 8 As shown, the guide rail 50 generally has a longitudinal and a transverse surface, so a measuring point is set on each of the longitudinal and transverse surfaces, and a reflector 101 may be placed at one of the measuring points to assist in the measurement. Figure 4 and Figure 5 P3, P4, P5, P6, P9, P10, P11 and P12.

[0146] Furthermore, if Figure 3 and Figure 4 As shown, a total station 100 is set up at a suitable position of the loading position, a custom benchmark is set, and then the coordinate data of the aforementioned 18 position points are measured in sequence, and the data of the 18 coordinate points are respectively:

[0147] P1(x1,y1,z1), P2(x2,y2,z2), P3(x3,y3,z3), P4(x4,y4,z4), P5(x5,y5, z5), P6(x6,y6,z6), P7(x7,y7,z7), P8(x8,y8,z8), P9(x9,y9,z9), P10(x 10 ,y 10 ,z 10 ), P11(x 11 ,y 11 ,z 11 ), P12(x 12 ,y 12 ,z 12 ), P13(x13 ,y 13 ,z 13 ), P14(x 14 ,y 14 ,z 14 ), P15(x 15 ,y 15 ,z 15 ), P16(x 16 ,y 16 ,z 16 ), P17(x 17 ,y 17 ,z 17 ), P18(x 18 ,y 18 ,z 18 ).

[0148] The aforementioned 18 coordinate point data are aggregated into an initial coordinate data set.

[0149] Step 3: Based on the initial coordinate data set, a primary assembly solution including bottom cone position data, adjustment plate thickness data, and guide block position data is obtained.

[0150] Specifically, Fig.16 As shown, the longitudinal spacings of the four guide rails are calculated from the initial coordinate data set to be d1 and d2, the transverse spacings of the four guide rails are e1 and e2, the longitudinal spacings of the four bottom cone simulation position centers are a1 and a2, the transverse spacings of the four bottom cone simulation position centers are b1 and b2, the diagonal distances of the four bottom cone simulation position centers are c1 and c2, the longitudinal spacings from the four bottom cone simulation position centers to the nearest guide rail are m1, m2, m3 and m4, and the transverse spacings from the four bottom cone simulation position centers to the nearest guide rail are n1, n2, n3 and n4; the transverse deviations k1 and k2 based on the inner side of the guide block and the inner side of the bow and stern guide rails are taken as references. Among them, the bottom cone simulation position centers corresponding to m1 and n1 are diagonally opposite to the bottom cone simulation position centers corresponding to m4 and n4, and the bottom cone simulation position centers corresponding to m1 and n1 are in the same longitudinal direction as the bottom cone simulation position centers corresponding to m2 and n2.

[0151] Where d0 = x4 - x 11 , d2=x5-x 10 , e1=y6-y3, e2=y9-y 12 , a1=x2-x1, a2=x7-x8, b1=y7-y2, b2=y8-y1.

[0152] The design value of the longitudinal spacing between the centers of the input bottom cones is A (for example, 11985 mm), and the design value of the lateral spacing between the centers of the input bottom cones is B (for example, 2259 mm). 11985 mm is the design distance for the longitudinal direction of the bottom cone, and 2259 mm is the design distance for the lateral direction of the bottom cone.

[0153] The standard value of the longitudinal distance from the center of the four bottom cone simulation positions to the nearest guide rail is calculated as The standard value of the lateral distance from the center of the four bottom cone installation position lines to the nearest guide rail is calculated as

[0154] Automatically adjust the horizontal and vertical coordinate data of the four bottom cone simulation position centers so that m1, m2, m3, and m4 are adjusted to satisfy m'1, m'2, m'3, and m'4, and n1, n2, n3, and n4 are adjusted to satisfy n'1, n'2, n'3, and n'4. The corresponding coordinate data of the bottom cone simulation position changes inversely to P1'(x'1, y'1, z'1), P2'(x'2, y'2, z'2), P7'(x'7, y'7, z'7), and P8'(x'8, y'8, z'8).

[0155] Then recalculate

[0156] Calculate |c′1-c′2|, and determine the difference between |c′1-c′2| and a preset difference threshold M, assuming that M=4 mm.

[0157] If |c′1-c′2|<M, the final solution of the bottom cone position data is obtained.

[0158] If |c′1-c′2|≥M, and if c′1>c′2, the two diagonal bottom cone simulation position centers corresponding to c′1 move closer along the longitudinal direction according to the preset displacement; the two diagonal bottom cone simulation position centers corresponding to c′2 move away along the longitudinal direction according to the preset displacement. Specifically, for example, x2 moves 1mm to the stern, x1 moves 1mm to the stern, x7 moves 1mm to the bow, and x8 moves 1mm to the bow, and then recalculate c′1 and c′2 until |c′1-c2|<4mm, and the adjustment is completed.

[0159] If c′1<c′2, the two diagonal bottom cone simulation positions corresponding to c′1 move away from each other according to the preset displacement in the longitudinal direction; the two diagonal bottom cone simulation positions corresponding to c′2 move closer to each other according to the preset displacement in the longitudinal direction. Specifically, x2 moves 1mm toward the bow, x1 moves 1mm toward the bow, x7 moves 1mm toward the stern, and x8 moves 1mm toward the stern, and then c′1 and c′2 are recalculated until |c′1-c′2|<4mm, and the adjustment is completed.

[0160] After the adjustment of the centers of the four bottom cone simulation positions is completed, the initial coordinates of the bottom cone simulation positions obtained in step 2 are subtracted from the adjusted coordinates to obtain the adjustment direction and adjustment value of the bow, stern, left and right of each bottom cone.

[0161] Among them, for the calculation of the adjustment plate thickness data, such as Fig. 9 As shown, the vertical coordinate data at the simulated position of each adjustment plate, that is, the z-axis coordinate data of P1, P2, P7, P8, P13, P14, P15 and P16, are determined by the initial coordinate data set.

[0162] The simulated position of the adjustment plate with the lowest vertical coordinate data is used as the horizontal reference point, for example Fig. 9 In the figure, the adjustment plate at the lower right corner is the reference point, and its levelness is recorded as 0. The measured data of the levelness of other adjustment plates becomes the z-direction data of the corresponding point minus the reference point. Assuming that all levels are adjusted to 14, that is, the thickness data of the adjustment plate at the reference point is 14mm, and the levelness of other adjustment plates is adjusted to 14, the corresponding thickness of the adjustment plate can be obtained by calculating with their respective measured levelness data.

[0163] That is, the thickness data of each adjustment plate is determined by the height difference data of each adjustment plate simulation position, see Fig. 9 The modified plate thickness on the middle right is the adjusted plate thickness data in the primary assembly plan.

[0164] Furthermore, the lateral deviation between the inner side of the guide block and the inner side of the bow and stern guide rails is and

[0165] for Fig. 9 For example, the unit of the data in the figure is mm, and the data in the figure represents the data changes. For example, the diagonal lines are 12201 and -6, which means the modified value of the diagonal distance of the center of the bottom cone simulation position and the difference compared with the previous value; for another example, 116 and the downward arrow indicates 6, which means that the distance from the center of the bottom cone simulation position to the inner edge of the guide rail is 116mm, which needs to be moved 6mm to the stern compared with the previous value; for another example, the lead distance is 2, which means that the lateral distance between the two guide blocks has increased by 2mm compared with the previous value.

[0166] Step 4: Fig.13 and Fig.14 As shown, according to the primary assembly plan obtained in step 3, the adjustment plate and the bottom cone are spot welded and installed, and the spot welding position of the guide block is adjusted.

[0167] Step 5: Establish coordinate points of the simulated test box at the bottom cone, the adjustment plate, the guide block, and the guide rail, obtain the coordinate data of each coordinate, and establish a verification coordinate data set.

[0168] Specifically, specifically, such as Fig.13 As shown, at the bottom cone 20, a bottom cone measuring fixture 22 is set up, and the top of the bottom cone measuring fixture 22 is used as the simulation test box coordinate point of the bottom cone. The height difference from the adjustment plate here is h. There are four bottom cones, and a total of 4 measuring points are set, namely Fig.11 and Fig.12 N1, N2, N7 and N8 in the figure. Since the coordinate points of the simulated test box of the adjustment plate at the four corners can be converted through N1, N2, N7 and N8.

[0169] like Fig.14 As shown, a guide block simulation coordinate point is set on a side wall of the guide block 40 facing the loading position, and two guide blocks 40 correspond to two measurement points, namely Fig.11 and Fig.12 The adjusting plate 30 corresponding to the 20-foot container foot is spot welded on the foot web 10 inside the guide block 40. The center of the adjusting plate 30 can be used as a measuring point, where a reflector can be placed. Four adjusting plates 40 in the middle need to be set, namely Fig.11 and Fig.12 N13, N14, N15 and N16.

[0170] In addition, two measuring points are set on each guide rail 50 (the same as in step S2), and there are four guide rails 50, totaling 8 measuring points, namely Fig.11 and Fig.12 N3, N4, N5, N6, N9, N10, N11 and N12.

[0171] Furthermore, if Fig.11 and Fig.12 As shown, a total station 100 is set up at a suitable position of the loading position, a custom benchmark is set, and then the coordinate data of the aforementioned 18 position points are measured in sequence, and the data of the 18 coordinate points are respectively:

[0172] N1(nx1,ny1,nz1), N2(nx2,ny2,nz2), N3(nx3,ny3,nz3), N4(nx4,ny4,nz4), N5(nx5,ny5, nz5), N6(nx6,ny6,nz6), N7(nx7,ny7,nz7), N8(nx8,ny8,nz8), N9(nx9,ny9,nz9), N10(nx 10 ,ny 10 ,nz 10 ), N11(nx 11 ,ny 11 ,nz 11 ), N12(nx 12 ,ny 12 ,nz 12 ), N13(nx13 ,ny 13 ,nz 13 ), N14(nx 14 ,ny 14 ,nz 14 ), N15(nx 15 ,ny 15 ,nz 15 ), N16(nx 16 ,ny 16 ,nz 16 ), N17(nx 17 ,ny 17 ,nz 17 ), N18(nx 18 ,ny 18 ,nz 18 ).

[0173] The aforementioned 18 coordinate point data are aggregated into a verification coordinate data set.

[0174] Step 6: Based on the verification coordinate data set, determine whether the installation position of each limit outfitting component meets the preset tolerance threshold; if it does, perform final welding; if it does not, obtain a corrected assembly plan based on the verification coordinate data set at least including the bottom cone position data, the adjustment plate thickness data, and the guide block position data, replace the adjustment plate, correct the bottom cone position, correct the guide block position, and repeat steps 5 to 6.

[0175] If the preset tolerance threshold is not met, the steps of obtaining a revised assembly solution including at least bottom cone position data, adjustment plate thickness data, and guide block position data based on the verification coordinate data set are described below.

[0176] Specifically, refer to Fig.16 , the longitudinal spacings of the four guide rails are calculated from the calibration coordinate data set to be d n1 and d n2 The lateral spacings of the four guide rails are e n1 and e n2 The longitudinal spacings between the centers of the four bottom cones are a n1 and a n2 The lateral spacings between the centers of the four bottom cones are b n1 and b n2 The diagonal distances between the centers of the four bottom cones are c n1 and c n2 The longitudinal distances from the center of the four bottom cones to the nearest guide rail are m n1 、m n2 、m n3 and m n4 The lateral distances from the center of the four bottom cones to the nearest guide rail are n n1 、nn2 、n n3 and n n4 ; Transverse deviation k based on the inner side of the guide block and the inner side of the bow and stern guide rails n1 and k n2 Among them, m n1 and n n1 The corresponding bottom cone center and m n4 and n n4 The corresponding bottom cone center is at the diagonal, m n1 and n n1 The corresponding bottom cone center and m n2 and n n2 The centers of the corresponding bottom cones are in the same longitudinal direction.

[0177] Among them, d n1 =nx4-nx 11 , d n2 =nx5-nx 10 , e n1 =ny6-ny3,e n2 =ny9-ny 12 , a n1 =nx2-nx1,a n2 =nx7-nx8, b n1 =ny7-ny2,b n2 =ny8-ny1.

[0178] The design value of the longitudinal spacing between the centers of the input bottom cones is A (for example, 11985 mm), and the design value of the lateral spacing between the centers of the input bottom cones is B (for example, 2259 mm). 11985 mm is the design distance for the longitudinal direction of the bottom cone, and 2259 mm is the design distance for the lateral direction of the bottom cone.

[0179] The standard value of the longitudinal distance from the center of the four bottom cones to the nearest guide rail is calculated as The standard value of the lateral distance from the center of the four bottom cones to the nearest guide rail is calculated as

[0180] Automatically adjust the horizontal and vertical coordinate data of the four bottom cone centers so that m n1 、m n2 、m n3 、m n4 Adjust to satisfy m″1, m″2, m″3, m″4, and make n n1 、n n2 、n n3 、n n4Adjust to satisfy n″1, n″2, n″3, n″4. The data of the corresponding coordinate points of the bottom cone change inversely and become N1′(nx′1,ny′1,nz′1), N2′(nx′2,ny′2,nz′2), N7′(nx′7,ny′7,nz′7), N8′(nx′8,ny′8,nz′8).

[0181] Then recalculate

[0182] Calculate |c″1-c″2| and determine the difference between |c″1-c″2| and a preset difference threshold M, assuming that M=4 mm.

[0183] If |c″1-c″2|<M, the final solution of the bottom cone position data is obtained.

[0184] If |c″1-c″2|≥M, and if c″1>c″2, the centers of the two diagonal bottom cones corresponding to c″1 move closer along the longitudinal direction according to the preset displacement amount; the centers of the two diagonal bottom cones corresponding to c″2 move away along the longitudinal direction according to the preset displacement amount. Specifically, for example, nx2 moves 1mm toward the stern, nx1 moves 1mm toward the stern, nx7 moves 1mm toward the bow, and nx8 moves 1mm toward the bow, and then c″1 and c″2 are recalculated until |c″1-c″2|<4mm, and the adjustment is completed.

[0185] If c″1<c″2, the centers of the two diagonal bottom cones corresponding to c″1 move away longitudinally according to the preset displacement; the centers of the two diagonal bottom cones corresponding to c″2 move closer longitudinally according to the preset displacement. Specifically, nx2 moves 1mm toward the bow, nx1 moves 1mm toward the bow, nx7 moves 1mm toward the stern, and nx8 moves 1mm toward the stern, and then c″1, c″2 are recalculated until |c″1-c″2|<4mm, and the adjustment is completed.

[0186] After the adjustment of the centers of the four bottom cones is completed, the coordinates of the bottom cone obtained in step 5 are subtracted from the adjusted coordinates to obtain the adjustment direction and adjustment value of the bow and stern, left and right of each bottom cone.

[0187] Among them, for the calculation of the adjustment plate thickness data, such as Fig.15 As shown, the vertical coordinate data at each adjustment plate is determined by the verification coordinate data set, that is, the z-direction coordinate data of N1, N2, N7, and N8 minus h, and the z-direction coordinate data of N13, N14, N15, and N16.

[0188] The adjustment plate with the lowest vertical coordinate data is used as the horizontal reference point, for example Fig.15In the figure, the adjustment plate at the lower right corner is the reference point, and its levelness is recorded as 0. The measured data of the levelness of other adjustment plates becomes the z-direction data of the corresponding point minus the reference point. Assuming that all the levelness is adjusted to 1, that is, the thickness data of the adjustment plate at the reference point needs to be increased by 1mm, and the levelness of other adjustment plates is adjusted to 1. By calculating with their respective measured levelness data, the thickness of the corresponding adjustment plate can be obtained, and then the thickness data of each adjustment plate can be determined, and then the thickness data of each adjustment plate can be used. Fig.15 Replacement of the adjustment plate corresponding to the plate thickness after the mid-term modification Fig. 9 Adjustment plate corresponding to the changed plate thickness.

[0189] Furthermore, the lateral deviation between the inner side of the guide block and the inner side of the bow and stern guide rails is and This can determine the adjustment plan for the guide block.
