Description

Technical Field

[0001] The present application relates to the technical field of welding training, and in particular to an integrated welding platform for training welders in cargo holds of LNG ships. Background Art

[0002] In recent years, with the acceleration of the transformation of energy structures around the world, the demand for natural gas consumption in various countries has also increased year by year. Therefore, how to efficiently, stably and safely transport liquefied natural gas to all parts of the world has become an urgent problem to be solved. In this process, LNG ships stand out among various major transportation tools with their advantages such as low evaporation rate and high stability. It can be said that the emergence of LNG ships has solved the problem of safe and efficient transportation of natural gas in cross-border trade. It is also the most efficient transportation tool on the market so far. LNG ships are favored by more and more regions and countries due to their excellent performance.

[0003] The entire shielding system of the cargo tank uses a large amount of invar material, all of which are connected by welding to form two complete shielding films. The thinnest part of the entire shielding film is only 0.7mm. The welding on it is also likened to "embroidery" on the steel plate in the industry. It can be seen that the difficulty of welding is great. At the same time, the main shield of the cargo tank is the first barrier that directly contacts the liquid natural gas, and its requirements for air tightness are very high. In summary, it can be seen that the safe and efficient storage of ultra-low temperature liquid natural gas in the cargo tank of the LNG ship is based on the excellent and reliable welding technology quality. The welding quality determines the overall stability and reliability of the film of the liquid cargo containment system, so how to efficiently and stably train the welders of the liquid cargo containment system is particularly important.

[0004] The emergence of welding training platform, coupled with a reasonable examination and re-certification process, has effectively solved the difficulties faced by shipyards in welder training, ensuring the rationality and efficiency of welder training, as well as the technical reliability of welders, and providing a strong guarantee for the welding quality of the membrane of the liquid cargo containment system.

[0005] However, when the existing welding platforms for cargo hold welder training are used for training, the welding angle of a single welding platform cannot be adjusted, and multiple platforms are required to cooperate to meet the simulation of actual ship welding conditions. In addition, the height of the welding platform cannot be adjusted, and the welding convenience cannot be guaranteed for welders of different heights, which is not conducive to welder training. Therefore, the original welding platform has the problems of poor flexibility and compatibility. Summary of the invention

[0006] The embodiment of the present application provides an integrated welding platform for LNG ship cargo hold welder training, which has a simple structure and strong flexibility, and can simulate a variety of actual ship welding conditions, greatly reducing the types of training platforms and saving space.

[0007] An embodiment of the present application provides an integrated welding platform for training welders in LNG ship cargo holds, the integrated welding platform comprising a base, a first column and a first operating platform; the first column is extended and arranged on the base in a vertical direction; the first operating platform is slidably arranged on the first column in a vertical direction so that the height of the first operating platform is adjustable; wherein a rotating unit is arranged between the first operating platform and the first column, the rotating unit being used to enable the first operating platform to flip relative to the first column so that the angle of the first operating platform is adjustable.

[0008] In this solution, the first operating platform can be used to place the workpiece to be welded, and the welder can perform welding training exercises on the first operating platform. The first operating platform is slidably arranged on the first column in the vertical direction, so that the position of the first operating platform on the first column is adjustable. When used by welders of different heights, the welder can adjust the height of the first operating platform according to his own situation or the training welding needs of different heights, so that the welder can better perform welding training exercises and simulate welding conditions of different heights, with a wider range of applications and strong compatibility. In addition, by providing a rotating unit between the first operating platform and the first column, the rotating unit can enable the first operating platform to flip relative to the first column, so that the angle of the first operating platform is adjustable to meet the needs of simulating welding conditions at different angles of the actual ship. In this way, during actual training, the welder can adjust the first operating platform to the corresponding angle to simulate actual welding scenes at different angles, with strong flexibility. That is, by making the height and angle of the first operating platform in the integrated welding platform adjustable, one integrated welding platform can simulate a variety of different actual ship welding conditions, greatly reducing the types of training platforms, occupying less space, having strong flexibility, low maintenance costs, and low management pressure, which is conducive to the welding training operations of welders.

[0009] In some embodiments, the number of the first columns is two, and the two first columns are spaced apart and distributed on the base along a first direction, and the first direction is perpendicular to the vertical direction.

[0010] In the above technical solution, by setting the number of first columns to two, the two ends of the first direction of the first operating platform are respectively slidably matched with the first columns. Compared with a single first column that makes the first operating platform constitute a cantilever structure, the two first columns jointly provide the first operating platform with installation and guiding functions, so that the installation stability of the first operating platform is stronger. When welders are undergoing welding training, the stability is higher, which is conducive to the training of welders.

[0011] In some embodiments, the first operating platform is sleeved on the first column through a first sleeve, and a plurality of first locking holes are spaced apart along the vertical direction on the first column. The first sleeve can be selectively inserted into the first locking hole through a first positioning piece to prevent the first sleeve from sliding on the first column.

[0012] In the above technical solution, the first operating platform is sleeved on the first column through the first sleeve, and the first sleeve is sleeved on the first column and contacts and cooperates with the outer peripheral surface of the first column. Compared with the conventional slider slide groove structure, the contact area between the first sleeve and the first column is larger, the installation stability of the first operating platform on the first column is stronger, the bearing strength of the first operating platform is higher, and it is not easy for the first operating platform to fall off or collapse from the first column. By distributing a plurality of first locking holes at intervals along the vertical direction on the first column, the first positioning member is plugged and matched with the first locking holes, which plays a limiting function on the first sleeve to prevent the first operating platform from moving relative to the first column.

[0013] In some embodiments, the rotation unit includes an angle adjustment disk, a connecting shaft and a rotating rod, the angle adjustment disk is fixedly connected to the first sleeve; the connecting shaft is vertically arranged on the angle adjustment disk; the rotating rod is connected to the first operating platform, one end of the rotating rod is rotatably mounted on the connecting shaft, and the other end of the rotating rod has a second positioning member; wherein, the angle adjustment disk has a plurality of second locking holes distributed on the periphery of the connecting shaft; the second positioning member can be selectively penetrated and matched with any one of the plurality of second locking holes to make the angle of the first operating platform adjustable.

[0014] In the above technical solution, an angle adjustment disk is provided on the first sleeve, and a plurality of second locking holes are provided on the circumference of the angle adjustment disk. The first operating platform is rotatably arranged on the connecting shaft on the angle adjustment disk through a rotating rod. When the angle of the first operating platform needs to be adjusted, the second positioning member is separated from the second locking hole, and the first operating platform can be rotated to adjust the angle of the first operating platform. When the angle of the first operating platform is rotated to the right position, the second positioning member is inserted into the corresponding second locking hole on the angle adjustment disk.

[0015] In some embodiments, the integrated welding platform also includes a second operating platform component, which is disposed on the first operating platform and is detachably connected to the first operating platform; the second operating platform has a second operating platform for welding practice, and the area of ​​the second operating platform is smaller than that of the first operating platform.

[0016] In the above technical solution, through the setting of the second operating platform component, the second operating platform component is detachably connected to the first operating platform, and the second operating platform component can be detachably installed on the first operating platform according to the actual welding training needs. The welder can quickly switch between various training conditions to perform welding training exercises on the workpiece to be welded on the first operating platform or the second operating platform, and the integration is high. The two operating platforms can be combined or disassembled to achieve an integrated welding platform compatible with multiple training contents and save space. The area of ​​the second operating platform is smaller than that of the first operating platform. The welder can choose to perform welding training on the first operating platform according to the needs, for example, when the size of the workpiece to be welded is large, and when the size of the workpiece to be welded is reduced, the welder can choose to perform welding on the second operating platform, such as flat welding, vertical welding or overhead welding, to simulate the welding conditions of the actual ship.

[0017] In some embodiments, the second operating platform assembly also includes a base plate, a second column and an adjustment rod. The base plate is detachably connected to the first operating platform. The second column is vertically arranged on the base plate. The adjustment rod is slidably arranged on the second column through a second sleeve. The second operating platform is slidably arranged on the adjustment rod.

[0018] In the above technical solution, the adjusting rod is slidably mounted on the second column through the second sleeve, and the second operating platform is slidably arranged on the adjusting rod, so the second operating platform can be adjusted in the vertical direction and in the length direction of the adjusting rod, with strong flexibility, and the second operating platform is arranged on the first operating platform, so that the second operating platform can meet the adjustment of various angles when the position of the first operating platform and the position of the second operating platform are adjusted to simulate the welding conditions of a real ship.

[0019] In some embodiments, there are multiple adjustment rods, and the multiple adjustment rods are spaced apart along the length direction of the second column.

[0020] In the above technical solution, by setting the number of adjustment rods to multiple, the second operating platform can be selectively installed on the corresponding adjustment rods, so that the height adjustment of the second operating platform is faster and more flexible.

[0021] In some embodiments, a second locking member is disposed between the second sleeve and the second column. The second locking member is threadedly engaged with the second sleeve. One end of the second locking member is used to abut against the outer wall of the second column to prevent the second sleeve from sliding relative to the second column.

[0022] In the above technical solution, by providing the second locking member, the second locking member can be threadedly matched with the second sleeve, and by rotating the second locking member, the position of the second sleeve on the second column can be locked or unlocked.

[0023] In some embodiments, a third sleeve is arranged between the second operating platform and the adjusting rod, and the second operating platform is fixedly connected to the third sleeve; the third sleeve is sleeved on the adjusting rod, and a third locking member is arranged between the third sleeve and the adjusting rod, and the third locking member is threadedly engaged with the third sleeve, and one end of the third locking member is used to resist the outer wall of the adjusting rod to prevent the third sleeve from sliding relative to the adjusting rod.

[0024] In the above technical solution, by setting the third sleeve, the second operating platform can be slidably mounted on the adjusting rod through the third sleeve, so that the position of the second operating platform in the length direction of the adjusting rod can be adjusted. By setting the third locking member, the third locking member can be threadedly matched with the third sleeve, and by rotating the third locking member, the position of the third sleeve on the adjusting rod can be locked or unlocked, thereby ensuring the position stability of the second operating platform on the adjusting rod.

[0025] In some embodiments, the cross-sectional shape of the adjusting rod is circular; and / or the cross-sectional shape of the second column is circular.

[0026] In the above technical solution, by adopting a circular cross-sectional shape for the adjusting rod and / or the second column, when the second locking member or the third locking member is loosened, the second sleeve can rotate relative to the second column, or the third sleeve can rotate relative to the adjusting rod, so that the second operating platform can be flipped accordingly, thereby meeting the needs of overhead welding or oblique welding.

[0027] Beneficial effects of this program:

[0028] The integrated welding platform has diversified functions. A single welding platform can be used to simulate a variety of real ship welding conditions, which greatly reduces the types of training platforms, saves space, and reduces management and maintenance costs. The welding platform has strong structural flexibility and convenient mode switching. It can quickly switch between a variety of different welding conditions and can be operated by a single person, saving a lot of manpower and time, greatly improving training efficiency.

[0043] In this solution, the first operating platform 30 can be used to place the workpiece to be welded, and the welder performs welding training exercises on the first operating platform 30. The first operating platform 30 is slidably arranged on the first column 20 in the vertical direction, so that the position of the first operating platform 30 on the first column 20 is adjustable. When used by welders of different heights, the welder can adjust the height of the first operating platform 30 according to his own situation or the training welding needs of different heights, so that the welder can better perform welding training exercises and simulate welding conditions of different heights, with a wider range of applications and strong compatibility. In addition, by providing a rotating unit 40 between the first operating platform 30 and the first column 20, the rotating unit 40 can make the first operating platform 30 flip relative to the first column 20, so that the angle of the first operating platform 30 is adjustable to meet the welding conditions of different angles of the simulated real ship. In this way, during actual training, the welder can adjust the first operating platform 30 to the corresponding angle to simulate the actual welding scenes of different angles, with strong flexibility. That is, by making the height and angle of the first operating platform 30 in the integrated welding platform adjustable, an integrated welding platform 100 can simulate a variety of different actual ship welding conditions, greatly reducing the types of training platforms, occupying a small space, having strong flexibility, low maintenance costs, and low management pressure, which is conducive to the welding training operations of welders.

[0044] LNG ship, liquefied natural gas ship (abbreviated as "LNG ship", "LNG transport ship") refers to a "ship" specially used to transport liquefied natural gas.

[0045] The height of the first column 20 may be between 1.5m and 1.8m. The material of the first column 20 may be Q235 steel, which has high strength and extremely low failure rate, thereby greatly reducing maintenance costs.

[0046] In some embodiments, the number of the first columns 20 is two, and the two first columns 20 are spaced apart on the base 10 along the first direction, and the first direction is perpendicular to the vertical direction. By setting the number of the first columns 20 to two, the two ends of the first direction of the first operating platform 30 are respectively slidably matched with the first columns 20. Compared with a single first column 20 that makes the first operating platform 30 form a cantilever structure, the two first columns 20 jointly provide the first operating platform 30 with installation and guidance functions, so that the installation stability of the first operating platform 30 is stronger, and the stability is higher when the welder is undergoing welding training, which is conducive to the training of the welder.

[0047] The cross-sectional shape of the first pillar 20 may be circular, square, triangular, etc. Optionally, the cross-sectional shape of the first pillar 20 is circular. The first direction is the distribution direction of the two first pillars 20.

[0048] There are many ways for the first operating platform 30 to slide with the first column 20. The first column 20 may be provided with a corresponding slide groove or guide rail, and the first operating platform 30 slides with the slide groove or guide rail through a slider. Of course, the first operating platform 30 can also be sleeved on the first column 20 through a sleeve to achieve the sliding of the first operating platform 30 on the first column 20.

[0049] In some embodiments, the first operating platform 30 is sleeved on the first column 20 through the first sleeve 21. The first column 20 is provided with a plurality of first locking holes 22 spaced apart in the vertical direction. The first sleeve 21 can be selectively inserted into the first locking holes 22 through the first positioning member 23 to prevent the first sleeve 21 from sliding on the first column 20. The first operating platform 30 is sleeved on the first column 20 through the first sleeve 21. The first sleeve 21 is sleeved on the first column 20 and contacts and cooperates with the outer peripheral surface of the first column 20. Compared with the conventional slider and slide groove structure, the contact area between the first sleeve 21 and the first column 20 is larger, the installation stability of the first operating platform 30 on the first column 20 is stronger, the bearing strength of the first operating platform 30 is higher, and the phenomenon of the first operating platform 30 and the first column 20 falling off or collapsing is not likely to occur. By distributing a plurality of first locking holes 22 at intervals along the vertical direction on the first column 20 , the first positioning member 23 is plugged into and matched with the first locking holes 22 to limit the first sleeve 21 and prevent the first operating platform 30 from moving relative to the first column 20 .

[0050] Among them, the first positioning member 23 has a variety of insertion methods to achieve the limiting function of the first sleeve 21. The first positioning member 23 can be inserted into the first locking hole 22 below the bottom of the first sleeve 21. The first positioning member 23 provides the bottom of the first sleeve 21 with a bearing and limiting function, preventing the first operating platform 30 from moving downward, and limiting the first operating platform 30. The first positioning member 23 can be connected to the first sleeve 21 through a connecting line, so that the first positioning member 23 is not easy to lose, and the first positioning member 23 can move with the first sleeve 21, and the connecting line can be a line made of flexible material.

[0051] Alternatively, the first sleeve 21 may also be provided with a corresponding insertion hole, and the first positioning member 23 may be inserted into the insertion hole. The first positioning member 23 may be inserted into the first locking hole 22 after passing through the insertion hole on the first sleeve 21, so that the first positioning member 23 can prevent the first sleeve 21 from sliding on the first column 20. In addition, the first positioning member 23 may also be threadedly matched with the insertion hole on the first sleeve 21, and the first positioning member 23 may be rotated to adjust the first positioning member 23 to be inserted into the first locking hole 22, so that the first positioning member 23 is not easy to fall off from the first sleeve 21.

[0052] When the position of the first operating platform 30 needs to be adjusted, the first positioning member 23 can be removed, and the first operating platform 30 can slide on the first column 20 through the first sleeve 21. When the height of the first operating platform 30 is adjusted to the right position, the first positioning member 23 can be inserted into the corresponding locking hole again.

[0053] In some embodiments, please refer to Figure 2 The rotating unit 40 includes an angle adjustment disk 41, a connecting shaft 42 and a rotating rod 43.

An angle adjustment disk 41 is provided on the first sleeve 21, and a plurality of second locking holes 411 are provided on the circumference of the angle adjustment disk 41. The first operating platform 30 is rotated on the connecting shaft 42 on the angle adjustment disk 41 through a rotating rod 43. When the angle of the first operating platform 30 needs to be adjusted, the second positioning member 44 is separated from the second locking hole 411, and the first operating platform 30 can be rotated to adjust the angle of the first operating platform 30. When the angle of the first operating platform 30 is rotated to the right position, the second positioning member 44 is inserted into the corresponding second locking hole 411 on the angle adjustment disk 41.

[0054] The second positioning member 44 can be inserted into the rotating rod 43, and the second positioning member 44 can also be threadedly matched with the rotating rod 43, and one end of the second positioning member 44 can be inserted into the corresponding second locking hole 411. The angle adjustment disk 41 can be a circular disk or a semicircular disk. Exemplarily, the angle adjustment disk 41 is a semicircular disk.

The area of ​​the second operating platform 51 is smaller than that of the first operating platform 30. Welders can choose to conduct welding training on the first operating platform 30 according to their needs. For example, when the size of the workpiece to be welded is larger, they can choose to conduct welding on the second operating platform 51 when the size of the workpiece to be welded is smaller, such as practicing flat welding, vertical welding or overhead welding, to simulate the welding conditions of a real ship.

[0059] In some embodiments, there are multiple adjustment rods 54, and the multiple adjustment rods 54 are spaced apart along the length direction of the second column 53. By setting the number of adjustment rods 54 to be multiple, the second operating platform 51 can be selectively installed on the corresponding adjustment rods 54, and the height adjustment of the second operating platform 51 is faster and more flexible.

Through the provision of the third locking member 58, the third locking member 58 can be threadedly matched with the third sleeve 57, and by rotating the third locking member 58, the position of the third sleeve 57 on the adjusting rod 54 can be locked or unlocked, thereby ensuring the position stability of the second operating platform 51 on the adjusting rod 54.

[0063] Specifically, when the third locking member 58 is loosened, one end of the third locking member 58 is separated from the outer wall of the adjusting rod 54, and the third sleeve 57 can slide freely on the adjusting rod 54, so that the relative position of the second operating platform 51 on the adjusting rod 54 can be adjusted. When the position of the second operating platform 51 on the adjusting rod 54 is adjusted to the right position, the third locking member 58 is tightened, and one end of the third locking member 58 abuts against the outer wall of the adjusting rod 54, thereby preventing the third sleeve 57 from sliding relative to the adjusting rod 54. The third locking member 58 can be a locking screw.

[0064] In some embodiments, the cross-sectional shape of the adjusting rod 54 is circular; and / or the cross-sectional shape of the second column 53 is circular. By adopting the cross-sectional shape of the adjusting rod 54 and / or the second column 53 as a circle, when the second locking member 56 or the third locking member 58 is loosened, the second sleeve 55 can rotate relative to the second column 53, or the third sleeve 57 can rotate relative to the adjusting rod 54, so that the second operating platform 51 can be turned over accordingly, so as to meet the requirements of overhead welding or oblique welding.
