[0040] As Figures 1-4As shown, the utility model provides a welding system for the outer stringer of the short cylinder of stainless steel storage tank, include: inner support part 1 and outer pressure part 2. Inner support part 1 includes inner support round part, and the inner support round part includes disc base 1-1. Disc base 1-1 is provided with multiple inner support mechanisms along its circumferential direction. The inner support mechanism is movably arranged along the radial direction of disc base 1-1 to approach or move away from the short cylinder, and the short cylinder is supported from the inside of the short cylinder. Outer pressure part 2 is used to press the stringer to the outside of the short cylinder from the outside of the short cylinder to weld the short cylinder and the stringer.

[0041] In the embodiment, for example, the end surface of the inner support mechanism for contacting the short cylinder is a profile matched with the inner side surface of the short cylinder. The welding system supports and fixes the short cylinder from the inside of the short cylinder through the inner support mechanism of the support part, and presses the stringer to the outside of the short cylinder from the outside of the short cylinder through outer pressure part 2 to weld the short cylinder and the stringer. The welding system can ensure that the welding position of the short cylinder of the storage tank does not deviate during the entire welding process, thereby improving the welding precision and welding quality.

[0042] As Figure 2 shown, according to an embodiment of the utility model, the inner support mechanism includes an inner support guide rod 1-2 and an inner support plate 1-3 arranged along the radial direction of the short cylinder. The inner support guide rod 1-2 is movably arranged along the radial direction of disc base 1-1. The inner support plate 1-3 is connected with the inner support guide rod 1-2. The inner support plate 1-3 is driven to approach or move away from the short cylinder by moving the inner support guide rod 1-2 along the radial direction of disc base 1-1.

[0043] The welding system of the embodiment is convenient for loading and unloading the short cylinder by arranging the telescopic inner support mechanism. For example, disc base 1-1 is provided with multiple linear guides along its circumferential direction, and the inner support guide rod 1-2 is fixedly connected with the slider of the linear guide. The inner support plate 1-3 is supported from the inside of the short cylinder by moving the inner support guide rod 1-2 along the radial direction of disc base 1-1 through the slider.

[0044] Further, when the inner support mechanism supports the inner side surface of the short cylinder, the inner support plates 1-3 of multiple inner support mechanisms are spliced to form a complete circle matched with the inner side surface of the short cylinder, further ensuring the shape precision of the short cylinder.

[0045] As Figure 5 and 6As shown, according to an embodiment of the utility model, in addition to the disc base 1-1, the inner supporting circular component further comprises a guiding driving component. The guiding driving component comprises a guiding disc 1-7. The guiding disc 1-7 is arranged on the disc base 1-1 and rotatably arranged relative to the disc base 1-1. The guiding disc 1-7 is provided with a plurality of guiding grooves 1-8 corresponding to the inner supporting mechanism along the circumferential direction thereof. Along the circumferential direction of the guiding disc 1-7, the distance between the guiding grooves 1-8 and the center of the guiding disc 1-7 increases. The inner supporting guiding rod 1-2 is provided with a guiding column 1-9 on the side close to the guiding disc 1-7, one end of the guiding column 1-9 is arranged in the guiding groove 1-8, and the guiding column 1-9 is slidably arranged relative to the guiding groove 1-8. By rotating the guiding disc 1-7 relative to the disc base 1-1, the guiding grooves 1-8 drive the guiding column 1-9 to move along the radial direction of the disc base 1-1.

[0046] In the embodiment, for example, the guiding grooves 1-8 extend along the circumferential direction of the guiding disc 1-7 and extend in the arc shape towards the circumferential side of the guiding disc 1-7. By rotating the guiding disc 1-7 relative to the disc base 1-1, the guiding grooves 1-8 move, the guiding column 1-9 is clamped, the guiding column drives the inner supporting guiding rod 1-2 to move along the radial direction of the disc base 1-1, thereby realizing the extension and contraction of the inner supporting guiding rod 1-2 relative to the disc base 1-1.

[0047] As shown in the figure, Figure 7 According to an embodiment of the utility model, the disc base 1-1 can be provided with a driving gear 1-13. The driving gear 1-13 is arranged in mesh with the guiding disc 1-7, and by rotating the driving gear 1-13, the guiding disc 1-7 is driven to rotate relative to the disc base 1-1.

[0048] In the embodiment, for example, the driving gear 1-13 is connected with a motor. The motor is started to drive the driving gear 1-13 to rotate the guiding disc 1-7.

[0049] As shown in the figure, Figure 1 According to an embodiment of the utility model, a plurality of inner supporting circular components are arranged along the axial direction (i.e. the direction perpendicular to the disc base 1-1). A plurality of inner supporting circular columns 1-4 are arranged between the adjacent two inner supporting circular components to support the inner supporting circular components.

[0050] In the embodiment, the plurality of inner supporting circular components (for example, three inner supporting circular components) simultaneously support the inner side of the short cylinder from the inside of the short cylinder along the axial direction of the short cylinder, which can improve the shape precision of the short cylinder.

[0051] As shown in the figure, Figure 8As shown, according to one embodiment of the present invention, in addition to the inner supporting circular component, the inner supporting component 1 also includes a rotating mechanism. The rotating mechanism includes a rotating mechanism base 1-5 and a driven gear 1-6, the driven gear 1-6 being used to support the disc base 1-1 and the bottom of the short cylinder. The driven gear 1-6 is rotatably disposed relative to the rotating mechanism base 1-5 to drive the disc base 1-1 and the short cylinder to rotate.

[0052] The welding system of this embodiment, by driving the disc base 1-1 and the short cylinder to rotate via the driven gear 1-6, can control the welding position of the stringer on the outer side of the short cylinder. For example, the rotating mechanism may also include a driving gear 1-14, which meshes with the driven gear 1-14. The driving gear 1-14 can be connected to a motor. When the motor starts, it drives the driving gear 1-14 to rotate the driven gear 1-6.

[0053] like Figure 1 As shown, according to one embodiment of the present invention, in addition to the inner supporting circular component, the inner supporting component 1 also includes an inner supporting column 1-10 and a column inner supporting mechanism. The inner supporting column 1-10 is used to be placed inside the short cylinder, and the column inner supporting mechanism is disposed on the circumferential side of the inner supporting column 1-10. The column inner supporting mechanism includes an inner supporting column drive cylinder 1-11 and a column inner supporting plate 1-12 disposed along the radial direction of the disc base 1-1 (i.e., perpendicular to the axial direction of the inner supporting column 1-10). The column inner supporting plate 1-12 is connected to the telescopic rod of the inner supporting column drive cylinder 1-11. By extending and retracting the telescopic rod of the inner supporting column drive cylinder 1-11, the column inner supporting plate 1-12 is driven toward or away from the inner side of the short cylinder, so that the column inner supporting plate 1-12 supports or releases the inner side of the short cylinder.

[0054] In this embodiment, the inner support plate 1-12 of the column is used to support the welding position between the stringer and the short cylinder. For example, the inner support column 1-10 can be set in the middle of the disc base 1-1 and perpendicular to the disc base 1-1. The disc base 1-1, guide disc 1-7, rotating mechanism base 1-5, and driven gear 1-6 are rotatably connected to or spaced apart from the inner support column 1-10. That is, when the rotating mechanism drives the disc base 1-1 and the short cylinder to rotate, the inner support column 1-10 and the column inner support mechanism do not rotate accordingly. For example, a set of column inner support mechanisms is set between two adjacent inner support circular components.

[0055] According to one embodiment of the present invention, for example, the lower end of the inner support column 1-10 can be connected to the ground or to equipment fixed on the ground (e.g., such as...). Figure 8 The inner support base 1-15 shown is fixedly connected.

[0056] like Figure 3 and 4As shown, according to one embodiment of the present application, the outer pressing component 2 comprises an outer pressing column 2-1 and a clamping component. The clamping component is arranged on the side of the outer pressing column 2-1. The clamping component is used to clamp the stringer and press the stringer to the outer side of the short cylinder.

[0058] According to one embodiment of the present application, in addition to the outer pressing column 2-1 and the clamping component, the outer pressing component 2 further comprises a linear guide rail. The linear guide rail can be fixedly arranged on the ground or arranged on a fixed device on the ground, and the linear guide rail is arranged along the radial direction of the short cylinder. The outer pressing column 2-1 is slidably arranged relative to the linear guide rail, so as to drive the clamping component to approach or move away from the cylinder. For example, the clamping component can be a device similar to a grabber.

[0059] As shown in Figure 1 and 2 According to one embodiment of the present application, the outer pressing column 2-1 is provided with a support 2-2 on the side facing the short cylinder, and one support plate 2-3 is arranged on each side of the support 2-2. The support plate 2-3 is provided with a clamping sliding block 2-4 which can slide relative to the support plate 2-3. The clamping component comprises a clamping driving cylinder 2-5, two pull rods 2-6 and two clamping arms 2-7. The clamping driving cylinder 2-5 is arranged along the height direction of the outer pressing column 2-1. The telescopic rod of the clamping driving cylinder 2-5 penetrates the support 2-2 and is slidably arranged relative to the support 2-2. One end of the pull rod 2-6 is rotatably connected with the circumferential side of the telescopic rod of the clamping driving cylinder 2-5. The other end of the pull rod 2-6 is rotatably connected with the clamping sliding block 2-4. The clamping sliding block 2-4 is connected with one end of the clamping arm 2-7. By extending and retracting the telescopic rod of the clamping driving cylinder 2-5, the one end of the pull rod 2-6 is driven to move up and down, so that the other end of the pull rod 2-6 drives the two clamping sliding blocks 2-4 to approach or move away from each other, so that the other end of the two clamping arms 2-7 approaches or moves away from each other to clamp or release the stringer.

[0060] In this embodiment, the one end of the pull rod 2-6 moves up and down, which drives the clamping sliding block 2-4 connected with the other end of the pull rod 2-6 to slide relative to the support plate 2-3. For example, the two clamping arms 2-7 are arranged in parallel on the horizontal plane.

[0061] As shown in Figure 9 According to one embodiment of the present application, for example, the vertical section of the clamping sliding block 2-4 can be an I-shaped section. The support plate 2-3 is provided with a clamping guide groove 2-11, and the clamping sliding block 2-4 is slidably arranged relative to the clamping guide groove 2-11.

[0062] In the embodiment, the clamping slider 2-4 is designed as an I-shaped, cooperates with the support plate 2-3, and can be limited in the height direction and slid in the horizontal direction.

[0063] As shown in Figure 10 , according to one embodiment of the utility model, for example, the circumferential side wall of the telescopic rod of the clamping driving cylinder 2-5 is provided with two corresponding support arms 2-12. The two support arms 2-12 are provided with a rotating shaft 2-13 away from one end of the telescopic rod of the clamping driving cylinder 2-5. One end of the pull rod 2-6 is rotatably connected with the rotating shaft 2-13.

The circumferential side of the telescopic rod of the clamping driving cylinder 2-5 is provided with a plurality of groups of pull rods 2-6 and clamping arms 2-7 corresponding to the supports 2-2.

[0065] In the embodiment, the telescopic rod of the clamping driving cylinder 2-5 penetrates the plurality of supports 2-2 in sequence and is slidable relative to the plurality of supports 2-2. By the extension and retraction of the telescopic rod of the clamping driving cylinder 2-5, one end of the plurality of groups of pull rods 2-6 is simultaneously moved up and down to drive the plurality of groups of clamping arms 2-7 to simultaneously clamp or release the truss along the length direction of the truss, thereby ensuring the stability of the truss and the welding quality during the welding process.

[0066] As shown in Figure 11 , according to one embodiment of the utility model, in addition to the inner support component 1 and the outer pressure component 2, the welding system further comprises a welding component 3.

[0067] In the embodiment, the welding component 3 moves up and down relative to the welding column 2-10, so that the welding head of the welding component 3 welds (for example, laser welds) the truss along the length direction of the truss. For example, the bottom plate 2-9 is slidably arranged with a linear guide rail arranged on the ground, so that the outer pressure component approaches or moves away from the welding position of the truss and the short cylinder.
