[0028] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0029] A welding fixture for a gas storage tank, as shown in the reference. Figure 1 As shown, it includes a base 1 and a support column 2 set on the base 1. The support column 2 is set perpendicular to the base 1, and an inner support positioning component 3 for fixing the gas storage tank is provided on the support column 2.

[0030] Reference Figure 3 and Figure 4 As shown, the inner support positioning component 3 includes an upper arc-shaped positioning block 31 and a lower arc-shaped positioning block 32. The upper arc-shaped positioning block 31 and the lower arc-shaped positioning block 32 are separately arranged in the vertical direction. The upper arc-shaped positioning block 31 and the lower arc-shaped positioning block 32 can be adjusted according to the axial length of the gas storage tank. By splicing and fixing the ends of multiple upper arc-shaped positioning blocks 31 or lower arc-shaped positioning blocks 32 together, the length direction of the upper arc-shaped positioning block 31 or the lower arc-shaped positioning block 32 can be changed to adapt to gas storage tanks of different length specifications.

[0031] The end of the upper arc-shaped positioning block 31 is fixed to the supporting column 2. An mounting plate 33 is provided within the upper arc-shaped positioning block 31, and a main inner support cylinder 34 is mounted on the mounting plate 33. The output rod of the main inner support cylinder extends and retracts vertically. The output rod of the main inner support cylinder 34 is fixed to the lower arc-shaped positioning block 32. The main inner support cylinder 34 serves two purposes: firstly, it connects the upper arc-shaped positioning block 31 and the lower arc-shaped positioning block 32; secondly, it drives the lower arc-shaped positioning block 32 to move vertically, thus expanding it from the inside out.

[0032] The upper arc-shaped positioning block 31 is equipped with a secondary inner support cylinder 35. The output rod of the secondary inner support cylinder 35 is fixed on the lower arc-shaped positioning block 32. The extension and retraction direction of the output rod of the secondary inner support cylinder 35 is the same as that of the output rod of the main inner support cylinder 34. Multiple secondary inner support cylinders 35 are provided, and the number of secondary inner support cylinders 35 is adjusted based on the axial length of the upper arc-shaped positioning block 31 and the lower arc-shaped positioning block 32.

[0033] Reference Figure 2 As shown, when the gas storage tank is fitted outside the upper arc-shaped positioning block 31 and the lower arc-shaped positioning block 32, the lower arc-shaped positioning block 32 is moved vertically by the main inner support cylinder 34, thereby realizing that the upper arc-shaped positioning block 31 and the lower arc-shaped positioning block 32 are stretched from the inside to the outside to fix the gas storage tank, and also playing the role of making the gas storage tank round.

[0034] The inner support positioning component 3 is provided with multiple joint positioning components 4, wherein the multiple joint positioning components 4 are located in the upper arc-shaped positioning block 31, that is, the joint positioning components 4 are located between the upper arc-shaped positioning block 31 and the lower arc-shaped positioning block 32.

[0035] The outer wall of the gas tank needs to be welded with a top bracket, bottom support legs and multiple joints to adapt to subsequent use. The joint positioning component 4 is used to position the joints. The gas tank has pre-drilled openings for each joint. When the gas tank is assembled into the inner support positioning component 3, each opening on the gas tank will be aligned with each joint positioning component 4. The joint positioning component 4 extends out from the opening of the gas tank to facilitate the positioning of the joints and the outer wall of the gas tank.

[0036] Specifically, refer to Figure 5As shown, the connector positioning assembly 4 includes a support plate 41 and a connector positioning cylinder 42 fixed on the support plate 41. A positioning rod 43 is connected to the output rod of the connector positioning cylinder 42. The positioning rod 43 passes through the upper arc-shaped positioning block 31. When the gas tank is assembled into the inner support positioning assembly 3, the positioning rod 43 will pass through the opening of the gas tank. The positioning rod 43 is used for connector fitting. The end of the positioning rod 43 is provided with a connector fixing part 44. The connector fixing part 44 is used to limit the sliding of the connector and play a role in fixing the connector. The connector positioning cylinder 42 can drive the positioning rod 43 to move, thereby tightening the connector on the outer wall of the gas tank.

[0037] The connector fixing part 44 includes a fixing end 441 and a fixing sleeve 442. The fixing end 441 is located at the end of the positioning rod 43. A fixing ring groove 443 is provided on the fixing end 441, and a fixing groove 444 is provided on the fixing sleeve 442. The fixing sleeve 442 is fitted onto the fixing end 441 through the fixing groove 444 and the fixing ring groove 443. The fixing sleeve 442 restricts the axial sliding of the connector on the positioning rod 43, thereby positioning the connector on the gas storage tank.

[0038] The number of connector positioning components 4 and the orientation of the positioning rods 43 in the connector positioning components 4 are set according to the actual gas storage tank processing conditions.

[0039] Reference Figure 1 and Figure 6 As shown, at least one support foot positioning block 5 is provided on the base 1. In one embodiment, there are four support foot positioning blocks 5, which are located at the four corners of the gas storage tank. Support foot positioning grooves 6 are provided on the support foot positioning blocks 5, and support foot positioning columns 7 are provided in the support foot positioning grooves 6. Support foot positioning cylinders 8 are provided on the base 1, and the output rod of the support foot positioning cylinder is connected to the support foot positioning blocks 5.

[0040] Reference Figure 1 As shown, a support beam 9 is slidably installed on the upper part of the inner support positioning component 3 in the vertical direction. The base 1 has support frames 10 on both sides of the inner support positioning component 3. A sliding guide rod 11 is slidably installed on the support frame 10. The sliding guide rod 11 is set in the vertical direction, and the end of the sliding guide rod 11 is fixed on the support beam 9, thereby realizing that the support beam 9 slides in the vertical direction above the inner support positioning component 3.

[0041] The base 1 is provided with a lifting assembly for driving the support beam 9 to move up and down. In one embodiment, the lifting assembly includes beam lifting cylinders 12 respectively disposed on both sides of the base 1, and the output rods of the two beam lifting cylinders 12 are respectively fixed at both ends of the support beam 9.

[0042] Reference Figure 1 and Figure 7As shown, a bracket positioning frame 13 is provided on the supporting beam 9. The bracket positioning frame 13 is used to position the top bracket assembled on the top of the gas storage tank. At least one bracket positioning column 14 is provided on the bracket positioning frame 13, and at least one magnet (not shown in the figure) is provided on the inner wall of the bracket positioning frame 13. (Refer to...) Figure 1 and Figure 8 As shown, a capacitor positioning frame 15 is also provided on the support beam 9. The capacitor positioning frame 15 is used to position the capacitor support assembled on the top of the gas storage tank. A magnet (not shown in the figure) is provided on the inner wall of the capacitor positioning frame 15.

[0043] The gas storage tank is assembled into the inner support positioning assembly 3, and the connector is sleeved onto the positioning rod 43 of the connector positioning assembly 4. The connector positioning assembly 4 pulls the connector tight and positions it on the outer wall of the gas storage tank.

[0044] Subsequently, the bottom support foot is assembled into the support foot positioning block 5, and the support foot positioning cylinder 8 drives the support foot positioning block 5 to move, pressing the bottom support foot firmly against the outer wall of the gas storage tank.

[0045] The top bracket is assembled into the bracket positioning frame 13, and the bracket positioning frame 13 magnetically holds the top bracket with the magnet in the top bracket. The capacitor bracket is assembled into the capacitor positioning frame 15, and the magnet in the capacitor positioning frame 15 magnetically holds the capacitor bracket. At this time, the lifting component drives the support beam 9 to move downward, thereby pressing the top bracket and the capacitor bracket tightly against the outer wall of the gas storage tank.

[0046] Therefore, by using welding equipment, the bottom support, top bracket and joint can be welded onto the gas storage tank in sequence without having to repeatedly clamp the gas storage tank, thus effectively improving the welding efficiency of various components on the gas storage tank.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
