Technical Field

[0001] This utility model relates to the field of oil tank floating plate technology, and in particular to an automatic welding device for oil tank floating plates. Background Technology

[0002] In offshore oil extraction and transportation, large floating tank vessels are primarily used. These large tanks are mostly floating roof tanks. Because the internal floating roof floats on the liquid surface, there is no gas phase, which can reduce crude oil evaporation loss by 85%-95%. It also reduces crude oil vibration during transportation, extends the tank's lifespan, and ensures transportation safety. Floating roof tanks are safer and more environmentally friendly than conventional tanks. As a crucial component of the floating roof tank, the welding of the floating roof plates is a key aspect of the tank construction process.

[0003] The welding of floating hull plates usually requires manual welding. Since stainless steel or iron floating hull plates are much heavier than aluminum ones, they are difficult to control during the welding process and are prone to deviation, which affects the welding effect.

[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes in detail, with reference to the accompanying drawings, an automatic welding device for floating plates of oil storage tanks according to an embodiment of the present invention.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of an automatic welding device for floating plates of oil storage tanks provided by this utility model includes a mounting frame 1, a guide rail 8 fixedly installed inside the mounting frame 1, a slider 9 slidably connected to the side wall of the guide rail 8, a welding gun 14 fixedly installed at the bottom of the slider 9, and adjustment mechanisms provided on both sides of the mounting frame 1.

[0027] The adjustment mechanism includes a connecting rod 2, a movable frame 3, a threaded adjusting component 4, a fixing component 5, and an electromagnet 13. The connecting rod 2 is fixedly installed on one side of the mounting frame 1. The movable frame 3 is slidably connected to the side wall of the connecting rod 2. The threaded adjusting component 4 is rotatably connected inside the movable frame 3. One end of the connecting rod 2 has a threaded groove 12. The threaded adjusting component 4 is movably connected inside the threaded groove 12. The fixing component 5 is fixedly installed at the bottom of the movable frame 3. The electromagnet 13 is fixedly installed at the bottom of the fixing component 5.

[0028] It should be noted that by setting the electromagnet 13, the fixing part 5 can be fixedly attached to the surface of stainless steel, iron or other magnetic floating plates, thereby fixing the movable frame 3 to the top of the floating plate. Then, by rotating the threaded adjustment part 4, the movable frame 3 can slide on the side wall of the connecting rod 2, thereby adjusting the distance between the two floating plates to be welded. This ensures that the welding gun 14 is always located at the welding line during the welding process, avoiding deviation, resulting in better welding effect and more convenient use.

[0029] In some embodiments, such as Figure 3 As shown, a limiting plate 11 is fixedly installed at one end of the connecting rod 2. The limiting plate 11 is slidably connected inside the movable frame 3. Both the movable frame 3 and the connecting rod 2 are rectangular.

[0030] It should be noted that by setting the limiting plate 11, the movable frame 3 can be prevented from detaching from the side wall of the connecting rod 2. Setting the movable frame 3 and the connecting rod 2 as rectangles can achieve the limiting effect and prevent rotation.

[0031] In some embodiments, such as Figure 4 As shown, a connecting pipe 10 is fixedly installed on the top of the slider 9, and the connecting pipe 10 is connected to the connecting end of the welding gun 14.

[0032] It should be noted that the welding gas required for welding can be injected into the welding gun 14 by setting the connecting pipe 10.

[0033] Example 2

[0034] In some embodiments, such as Figure 2 As shown, a threaded rod 7 is rotatably connected inside the mounting bracket 1. A servo motor 6 is fixedly installed on one side of the mounting bracket 1. The threaded rod 7 is fixedly installed at the output end of the servo motor 6. A threaded hole 15 is opened inside the slider 9. The threaded hole 15 fits with the threaded rod 7. The slider 9 is movably connected to the side wall of the threaded rod 7 through the threaded hole 15.

[0035] It should be noted that by setting the servo motor 6, the rotation of the threaded rod 7 can be controlled. The rotation of the threaded rod 7 can drive the slider 9 to slide on the side wall of the guide rail 8, thereby controlling the position of the slider 9 and the welding gun 14, thus achieving the effect of automatic welding, which is more convenient and saves time and effort.

[0036] In this utility model, the servo motor 6, electromagnet 13, and welding gun 14 are known components and will not be described in detail here.

[0037] Working principle: During use, the electromagnet 13 fixes the fixing part 5 to the surface of stainless steel, iron or other magnetic floating plates, thereby fixing the movable frame 3 to the top of the floating plate. Then, by rotating the threaded adjustment part 4, the movable frame 3 can slide on the side wall of the connecting rod 2, thereby adjusting the distance between the two floating plates to be welded, so that the welding gun 14 can always be located at the welding line during the welding process. The servo motor 6 is used to control the rotation of the threaded rod 7. The rotation of the threaded rod 7 drives the slider 9 to slide on the side wall of the guide rail 8, thereby controlling the position of the slider 9 and the welding gun 14, so that the welding gun 14 moves automatically along the welding line, thereby achieving the effect of automatic welding.

[0038] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
