Description

Technical Field

[0001] The present invention relates to the field of shipbuilding, and in particular to a transport device, a construction method of the transport device, and a construction component. Background Art

[0002] At present, the demand for the construction of car carriers is increasing. Such ships have large hulls, usually with up to 10-14 decks. There are many deck sections, and about three-quarters of the entire ship (three out of four sections) are deck sections. In order to improve construction efficiency and shorten the construction period, the number of deck sections that need to be built off-site accounts for about 30% of the entire ship. The off-site construction process of deck sections means that the sections are built at Factory A, then transported to the dock of Factory B, and then hoisted to the predetermined location.

[0003] The current transportation method is: the deck sections are transported from the workshop of Factory A to the dock, and the gantry crane is used to lift the deck sections one by one onto the barge, and the necessary fastening is performed on the deck sections. The barge transports them from Factory A to Factory B, and the gantry crane is used to lift the deck sections one by one onto the platform at the dock of Factory B. Therefore, in the existing transportation and lifting process, each time the deck sections are lifted from the barge to the dock platform, the gantry crane will be occupied once. Considering the large-scale transportation demand for car carrier deck sections, the original transportation method will occupy a large amount of dock gantry crane resources, which is very inefficient.

[0004] Improving transportation efficiency requires specialized transportation equipment to be manufactured for transportation. Existing traditional manufacturing methods have low construction efficiency and are not convenient for welding or assembly. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of low construction efficiency and inconvenience in welding or assembly of transport devices with transport deck sections in the prior art, and to provide a transport device, a construction method of the transport device and a construction component.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] A method for constructing a transport device, the method comprising:

[0008] Step 100: The transport device includes beams, a protective net and a guardrail, and the beams, the protective net and the guardrail of the transport device are constructed and / or prepared separately or simultaneously;

[0009] Step 200: numbering the beams and the guardrails, and setting numbers on the outer surfaces of the beams and the guardrails to facilitate identification and distinction of different beams;

[0010] Step 300: making and arranging the fetal position;

[0011] Step 400: assembling and connecting the beam, the protection net and the guardrail along the assembly direction on the fetal position;

[0012] Step 500: After assembly is completed, the transport device is obtained;

[0013] The staggered vertically arranged beams form a grid-like bearing portion of the transport device, the guardrails are circumferentially distributed around the transport device and are perpendicular to the beams, extending directly above the beams, and the guardrails are fixedly connected to the beams;

[0014] A protective net is arranged along the circumferential direction on the inner side of the bearing portion close to the edge, and the protective net is embedded in the gap between the adjacent beam members.

[0015] In this solution, by numbering and dividing the beams and guardrails on the surface, different beams can be easily identified and distinguished, so as to avoid confusion between beams arranged longitudinally and transversely during assembly or welding, thereby reducing the situation of wrong welding and increasing the construction efficiency. By making and arranging the tire positions, it is easy for operators to weld and assemble the transport device. By assembling the guardrails, the deck sections are prevented from being separated from the transport device during transportation. By setting the protective net in the inner gap of the load-bearing part, it is convenient for operators to walk. By assembling and connecting the beams, protective nets and guardrails on the tire positions along the assembly direction, the efficiency of building the transport device can be improved and welding is convenient.

[0016] Preferably, the step 200 specifically further includes:

[0017] Step 201: pre-treating the beam to improve welding operability and welding quality of the beam;

[0018] Wherein, the beam member includes a main beam and an auxiliary beam.

[0019] Preferably, in step 201, the preprocessing includes:

[0020] When the web and the face plate of the beam are welded, a root is left at one end of the web near the connection between the web and the face plate.

[0021] In this solution, a gap is reserved by leaving a root at one end of the connection between the web and the panel to ensure that the weld can be fully filled during welding, avoid welding defects caused by excessive weld thickness, reduce stress concentration generated during welding, and improve the overall stability of the structure.

[0022] Preferably, the step 300 specifically includes:

[0023] Marking a line on the ground according to the distribution of the center line of the beam;

[0024] Set up posts at the intersections of the marked lines;

[0025] The plurality of upright posts are distributed in a grid shape to form the fetal position.

[0026] In this solution, by making the distribution of the columns correspond to the intersection of the center lines of the beams, a tire position structure corresponding to the main load-bearing part of the transport device is formed, which is conducive to making the tire position evenly distributed when assembling the transport device, and fully playing the role of bearing and supporting the transport device during the assembly process.

[0027] Preferably, the assembly direction is from one end of the transport device to the other end thereof, with the start of the assembly direction being the first end and the end of the assembly direction being the last end;

[0028] In the steps for setting posts at the intersection of the scribed lines:

[0029] The arrangement position of the uprights in a row close to the end of the fetal position is translated toward the head end by a preset distance along the assembly direction.

[0030] In this solution, the setting position of the column in the row near the end is shifted by a preset distance along the assembly direction toward the head end, so as to avoid the formation of a cantilever beam structure at the end of the transversely arranged beam along the assembly direction. If the distribution is strictly in accordance with the intersection of the centerline of the beam, before the longitudinal beam in the end row is installed, the column in the end row cannot abut against the multiple beams distributed transversely. By adjusting the distance of the position in the end row, the column in the end row can support the end of the beam.

[0031] Preferably, the assembly direction is from one end of the transport device to the other end thereof, and step 400 specifically further comprises at least:

[0032] Assembling the beams in sequence according to the assembly direction;

[0033] Assembling the auxiliary beam according to the assembly direction;

[0034] Welding the main beam and the auxiliary beam;

[0035] A reinforcing rib is arranged at the intersection of the adjacent beams, and the two ends of the reinforcing rib are respectively fixedly connected to the two adjacent beams to enhance the structural stability of the beam;

[0036] Assembling the protective net, and fixing the outer periphery of the protective net to the main beam or the auxiliary beam around the protective net;

[0037] Assemble the guardrail.

[0038] Preferably, the construction method further comprises:

[0039] Step 500: Perform flaw detection on each weld of the beam, the protective net and the guardrail.

[0040] Step 501: Reinforce the weld according to the detection results.

[0041] In this solution, nondestructive testing is performed to ensure welding quality and protect the integrity and strength of the welds. Welds that do not meet quality requirements are reinforced based on the test results, thereby improving construction quality and reducing rework caused by weld quality issues.

[0042] Preferably, the construction method further comprises:

[0043] Step 601: Performing accuracy testing on the transport device to ensure that the accuracy of the transport device meets the requirements;

[0044] Step 602: Paint the transport device.

[0045] In this solution, the transport device is precision tested to ensure that the precision of the transport device after assembly meets the industry standard, thereby improving the construction quality of the transport device. After the transport device is painted, the corrosion resistance of the transport device can be increased.

[0046] The technical solution provided by the present invention also includes:

[0047] A transport device is constructed using the construction method described above.

[0048] A construction kit for a transport device, comprising a fetal position as described above.

[0049] The positive and progressive effects of the present invention are: by numbering and dividing the surface of beams and guardrails, it is easy to identify and distinguish different beams, avoid confusing the longitudinal and transverse beams during assembly or welding, thereby reducing the situation of wrong welding and increasing construction efficiency. By making and arranging the tire positions, it is easy for operators to weld and assemble the transportation device. By assembling guardrails, the deck sections are prevented from detaching from the transportation device during transportation. By setting a protective net in the inner gap of the load-bearing part, it is convenient for operators to walk. By assembling and connecting beams, protective nets and guardrails on the tire positions along the assembly direction, the efficiency of building the transportation device can be improved and welding is convenient.

[0074] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0075] like Figure 1-Figure 6 As shown, this embodiment provides a method for constructing a transport device 1, the method comprising:

[0076] S100: The transport device 1 includes a beam 20, a protective net 8 and a guardrail 3, and the beam 20, the protective net 8 and the guardrail 3 of the transport device 1 are constructed and / or prepared separately or simultaneously;

[0077] S200: Numbering the beams 20 and the guardrails 3, and setting numbers on the outer surfaces of the beams 20 and the guardrails 3 to facilitate identification and distinction of different beams 20;

[0078] S300: making and arranging fetal position 4;

[0079] S400: assembling and connecting the beam 20, the protection net 8 and the guardrail 3 along the assembly direction on the tire position 4;

[0080] S500: After assembly is completed, the transport device 1 is obtained;

[0081] like Figure 6 As shown, the staggered vertically arranged beams 20 form a grid-like load-bearing portion of the transport device 1, the guardrails 3 are circumferentially distributed around the transport device 1 and are perpendicular to the beams 20, extending directly above the beams 20, and the guardrails 3 are fixedly connected to the beams 20; a protective net 8 is circumferentially arranged on the inner side of the load-bearing portion near the edge, and the protective net 8 is embedded in the gap between adjacent beams 20.

[0082] In this embodiment, by numbering and dividing the surface of the beam 20 and the guardrail 3, it is easy to identify and distinguish different beams 20, avoid confusing the longitudinal and transverse beams 20 during assembly or welding, thereby reducing the situation of wrong welding and increasing the construction efficiency. By making and arranging the tire 4, it is easy for operators to weld and assemble the transport device 1. By assembling the guardrail 3, the deck section is prevented from detaching from the transport device 1 during transportation. By setting the protective net 8 in the inner gap of the load-bearing part, it is convenient for operators to walk. By assembling and connecting the beam 20, the protective net 8 and the guardrail 3 on the tire 4 along the assembly direction, the efficiency of building the transport device 1 can be improved and welding is convenient.

[0083] Among them, S200 specifically also includes:

[0084] S201: pre-treating the beam 20 to improve welding operability and welding quality of the beam 20;

[0085] The beam member 20 includes a main beam 201 and an auxiliary beam 202 .

[0086] As a specific implementation, in S201 , the pretreatment includes: when the web 21 and the face plate 22 of the beam 201 are welded, a root leaving treatment is performed on one end of the web 21 close to the connection between the web 21 and the face plate 22 .

[0087] In the specific implementation process, Figure 2As shown, by leaving a root at one end of the connection between the web 21 and the panel 22, a gap is reserved to ensure that the weld can be fully filled during welding, avoid welding defects caused by excessive weld thickness, reduce stress concentration generated during welding, and improve the overall stability of the structure.

[0088] As another embodiment of the welding process, Figure 2 and Figure 3 As shown, when welding between beams 201 and beams 201, and between beams 201 and auxiliary beams 202, the upper surfaces of the beams 201 and auxiliary beams 202 in transverse and longitudinal directions are kept flush, a groove 23 with a certain angle is reserved at the welding connection of the beam 201, and a gap 24 is reserved at the connection interface between the web 21 and the panel 22 for full filling of the weld, which facilitates the welding operation and increases the penetration of the weld, so that the weld is better combined with the parent material, thereby improving the strength of the weld.

[0089] In other embodiments, those skilled in the art may select specific pretreatment means and processes for combined welding as needed.

[0090] like Figure 4 and Figure 5 As shown, S300 specifically includes:

[0091] According to the distribution of the center line 40 of the beam 201, a line is drawn on the ground;

[0092] A column 400 is provided at the intersection 41 of the scribed lines;

[0093] The plurality of upright posts 400 are distributed in a grid pattern and form a fetal position 4 .

[0094] As a specific implementation of the arrangement of the fetal position 4, by making the distribution of the columns 400 correspond to the intersection of the center lines 40 of the beam 201, a fetal position 4 structure corresponding to the main load-bearing part of the transport device 1 is formed, which is beneficial for making the fetal position 4 evenly distributed when assembling the transport device 1, and fully playing the role of bearing and supporting the transport device 1 during the assembly process.

[0095] Among them Figure 4 As shown, the assembly direction is along one end of the transport device 1 to the other end thereof, with the beginning of the assembly direction being the head end and the end of the assembly direction being the tail end; in this embodiment, as a specific assembly direction, that is, assembly from left to right, the left end is the head end and the right end is the tail end.

[0096] Among them, in the step of setting the pillars 400 at the intersections 41 of the scribed lines:

[0097] The setting position of the column 400 in the row near the end of the tire position 4 is translated by a preset distance 42 toward the head end along the assembly direction. The setting position of the column 400 in the row near the end of the tire position 4 is translated by a preset distance 42 toward the head end along the assembly direction, so as to avoid the formation of a cantilever beam structure at the end of the transversely arranged beam 201 along the assembly direction. If the distribution is strictly in accordance with the intersection 41 of the center line 40 of the beam 201, before the longitudinal beam 201 in the end row is installed, the column 400 in the end row cannot abut against the multiple transversely distributed beams 201. By adjusting the distance of the tire position 4 in the end row, the column 400 in the end row can support the end of the beam 201.

[0098] like Figure 4 As shown, the assembly direction is from one end of the transport device 1 to the other end thereof, and S400 specifically further includes at least:

[0103] Assemble the protection net 8, and fix the outer periphery of the protection net 8 to the beam 201 or the auxiliary beam 202 around the protection net 8;

[0104] Assemble the guardrail 3.

[0105] During the above-mentioned assembly operation, operators in this field can selectively replace or simultaneously perform two or more of the above-mentioned assembly steps according to the actual assembly progress, including but not limited to assembling the auxiliary beam 202 in part after partially completing the assembly of the main beam 201; welding the main beam 201 and the auxiliary beam 202, and setting the reinforcing rib 5 at the same time.

[0107] S500: Perform flaw detection on each weld of the beam 20 , the protection net 8 and the guardrail 3 .

[0108] S501: Reinforce the weld according to the test results.

[0109] In this embodiment, nondestructive testing is performed to ensure welding quality, protect the integrity and strength of the weld, and reinforce welds that do not meet quality requirements based on the test results, thereby improving construction quality and reducing rework caused by weld quality issues.

[0110] As a specific implementation method of flaw detection, UT (Ultrasonic Testing) and MT (Magnetic Particle Testing) are performed on the weld surface of the beam 20 to detect whether there are area defects inside the weld by non-destructive non-destructive testing, and to observe whether there are cracks, pores and other places with low welding quality by magnetic particle testing. The quality of the weld is evaluated and reinforced as appropriate to increase the yield, thereby improving construction efficiency and ensuring construction quality.
