In a preferred embodiment, the welding tool 3 comprises a base body 31 and a first fixing mechanism and a second fixing mechanism arranged on the base body 31, wherein the first fixing mechanism comprises a first fixing part and a second fixing part, at least one of the first fixing part and the second fixing part is movably arranged on the base body 31 along the axial direction of the gas collecting main pipe 11, and the first fixing part and the second fixing part are respectively provided with a fixing structure at positions facing each other, so that in a state of welding preparation, the gas collecting main pipe 11 can be fixed between the first fixing part and the second fixing part through the fixing structure along the axial direction thereof.
The first fixing part and the second fixing part have various structural forms, and can be fixing blocks, fixing columns or other possible structures. As a possible example, as shown in fig. 4, the first fixing mechanism comprises two upright columns 32, and the upright columns 32 are provided with a fixing mechanism by which the main gas collecting pipe 11 can be fixed between the two upright columns 32. The base body 31 is provided with a slide rail 34, the upright column 32 is provided with a movable pulley 33, and the upright column 32 can slide on the slide rail 34 along the axial direction of the gas collecting main pipe through the movable pulley 33. Thus, the operator can adjust the distance between the two columns 32 adaptively according to the length of the main gas collecting pipe 11 fixed as required, thereby improving the universality of the welding tool 3. The moving pulley 33 is further provided with a positioning structure 331, and after the distance between the two upright columns 32 is adjusted, the operator switches the upright columns 32 from the movable state to the fixed state by limiting the movement of the upright columns 32 through the positioning structure 331.

Preferably, the fixing structure comprises a mounting part, the mounting part is provided with at least one mounting position, and in the case that the number of the mounting positions is multiple, the main gas collecting pipe can be matched and butted with one of the mounting positions. The structure of the mounting member can be various, for example, as shown in fig. 4, the mounting member 321 includes an elastic base body, the elastic base body is in a conical structure, and in a state that the gas collecting main pipe is mounted, the elastic base body is partially inserted into the pipe openings at two ends of the gas collecting main pipe 11 and tightly abuts against the outer edges of the pipe openings.

Furthermore, the elastic matrix is made of a rubber material with a flame retardant added inside, so that the elastic matrix has good flame retardant performance and friction performance, the friction force between the gas collection main pipe and the elastic matrix is increased, and the fixing stability of the gas collection main pipe is improved.
It should be noted that the shape of the elastic base is not limited to the above example, and may be other shapes with various radial dimensions, and those skilled in the art may flexibly set the shape of the elastic base according to actual situations. If the elastic base body can also be a step structure, the step structure is provided with steps with different radial sizes so as to be suitable for gas collecting main pipes with different pipe diameters.
Preferably, the fixed structure further comprises a support member disposed below the mount 321, the support member having a movement amount in the vertical direction so that gas header pipes of different radial dimensions can be abutted to the support member in the state of preparatory welding.

The spring pieces 322 can share most of the weight of the gas collecting main pipe 11, and reduce the acting force of the gas collecting main pipe 11 on the mounting piece 321, so that the fixing stability of the gas collecting main pipe 11 on the first fixing mechanism can be improved. In addition, because the spring plate has elasticity, the spring plate can adapt to the main gas collecting pipe with different radial sizes through self deformation, thereby meeting the fixing requirement of the main gas collecting pipe within a certain radial size range.
It should be noted that the fixing structure on the upright column 32 is not limited to the above-mentioned examples, and those skilled in the art can flexibly set the specific form of the fixing structure according to actual situations, as long as it can ensure reliable fixing of the gas collecting main pipe 11. As a possible example, the fixing structure includes mounting pieces disposed on the two columns 32, the mounting pieces include a docking portion and a barrel portion, the number of the mounting pieces is multiple, the plurality of mounting pieces have the same docking portion and barrel portions with different dimensions, the barrel portions with different dimensions correspond to the main gas collecting pipes with different radial dimensions, an operator can select the mounting piece with the corresponding dimension according to the radial dimension of the main gas collecting pipe to be currently installed, then the selected mounting piece is fixed to one side of the two columns 32 close to each other through the docking portion in a detachable manner (such as screwing or clamping), and then the barrel portion on the mounting piece is fixedly connected with the main gas collecting pipe in a manner of being sleeved outside the pipe orifice of the main gas collecting pipe.

It is understood that the first nitrogen introducing structure and the second nitrogen introducing structure are not limited to the nozzle, and those skilled in the art can flexibly set the specific structural form of the first nitrogen introducing structure and the second nitrogen introducing structure according to actual requirements so as to be capable of adapting to specific application scenarios.

The operator only needs to insert the two ends of the gas collecting branch pipe 12 into the through hole of the gas collecting main pipe 11 and the fixing hole 361 on the body 36 at the same time to fix the gas collecting branch pipe 12. After the welding operation is finished, the operator only needs to move the two vertical columns 32 away from each other to release the gas collecting main pipe 11, and then moves the gas collecting main pipe 11 upward to pull out the gas collecting branch pipes 12 from the fixing holes 361. It can be seen that through the above arrangement, the disassembly and assembly convenience of the gas collecting branch pipe 12 can be improved on the premise of ensuring the reliable fixation of the gas collecting branch pipe 12.
It will be appreciated that, in order to ensure that the gas collecting branch pipes 12 can be inserted into the through holes of the gas collecting main pipe 11 and the fixing holes 361 of the body 36 at the same time, the distance between the fixing holes 361 and the gas collecting main pipe 11 in the radial direction of the gas collecting main pipe is determined according to the size of the gas collecting branch pipes 12. As shown in fig. 2, the gas collecting branch pipes 12 of the existing gas collecting assembly have various sizes, and accordingly, corresponding fixing holes 361 can be provided on the body 36 according to the sizes of the gas collecting branch pipes 12, so that the gas collecting branch pipes 12 of different sizes can be reliably fixed on the same gas collecting branch pipe 12.
It should be noted that the specific structure of the second fixing mechanism is not limited to the above example, and as a possible example, the second fixing mechanism includes a body having a certain deformation capability, and when an operator inserts the second end of the gas collecting branch pipe into the body, the second end of the gas collecting branch pipe is fixed on the body in a manner of directly embedding into the body. As another possible example, the second fixing mechanism includes a body and a snap member movably provided on the body.

As a possible example, a first sliding rail and a second sliding rail are provided on the base body 31 in the axial and radial directions of the gas header main 11, on which at least one of the two uprights 32 can slide in order to adjust the distance between the two uprights 32 according to the length of the gas header main 11 to be fixed. The second fixing mechanism comprises a body 36, and the body 36 can slide on the second slide rail so as to adjust the distance between the body 36 and the upright column 32 along the radial direction of the main gas collecting pipe 11 according to the size of the main gas collecting pipe 12 to be fixed.
It will be understood that, in practical applications, for the purpose of enabling the distance between the first fixing means and the second fixing means in the radial direction of the gas header main 11 to be adjusted, the first fixing means or the second fixing means can be selectively made to be movable relative to the base body in the radial direction of the gas header main, or both the first fixing means and the second fixing means can be made to be movable relative to the base body in the radial direction of the gas header main. Moreover, a person skilled in the art can flexibly set the moving structure of the first fixing mechanism and/or the second fixing mechanism in practical situations, as long as the distance between the first fixing mechanism and the second fixing mechanism along the radial direction of the main gas collecting pipe can be adjusted.
