[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] As Figure 1 and Figure 2 shown, it includes a support mechanism 1 and a spreading mechanism 2. The support mechanism 1 is used to place the first furnace rib tube 19 and the second furnace rib tube 20.

[0032] The support mechanism 1 includes a first base 11 and a second base 12 for fixing. A welding area 3 is formed between the first base 11 and the second base 12. Welding sliders are provided on the first furnace rib tube 19 and the second furnace rib tube 20 located within the welding area 3.

[0033] The first base 11 is provided with a first through hole 111 and a second through hole 112 for fixing. The first through hole 111 and the second through hole 112 are respectively used to pass through the first furnace rib tube 19 and the second furnace rib tube 20. The second base 12 is provided with a third through hole 121 and a fourth through hole 122 for fixing. The third through hole 121 and the fourth through hole 122 are respectively used to pass through the first furnace rib tube 19 and the second furnace rib tube 20.

[0034] The first through hole 111 and the third through hole 121 are oppositely arranged, and the second through hole 112 and the fourth through hole 122 are oppositely arranged. The first furnace rib tube 19 is used to pass through the first through hole 111 and the third through hole 121, and the second furnace rib tube 20 is used to pass through the second through hole 112 and the fourth through hole 122.

[0035] A spreading area 4 is formed between the first through hole 111 and the second through hole 112 and between the third through hole 121 and the fourth through hole 122, that is, a spreading area 4 is formed between the first furnace rib tube 19 and the second furnace rib tube 20.

[0036] The spreading mechanism 2 includes a jack 21 and a support rod 22. The jack 21 is used to spread the first furnace rib tube 19 and the second furnace rib tube 20. Both ends of the support rod 22 are used to abut against the first furnace rib tube 19 and the second furnace rib tube 20, and the length of the support rod 22 is longer than the minimum distance between the first furnace rib tube 19 and the second furnace rib tube 20. In this way, the distance between the first furnace rib tube 19 and the second furnace rib tube 20 is enlarged by the support rod 22.

[0037] Both the first base 11 and the second base 12 are cubes, which is convenient for the first base 11 and the second base 12 to be flipped, and is also convenient for the welding of the first furnace rib tube 19 and the second furnace rib tube 20.

[0038] The first base 11 has an adjacent first side 13 and a second side 14, and the second base 12 has an adjacent third side 15 and a fourth side 16. The first side 13 and the third side 15 are on the same side, and the second side 14 and the fourth side 16 are on the same side. In the case of non-standard shapes, both the first base 11 and the second base 12 can be flipped in two directions, which is convenient for welding.

[0039] The first through hole 111 and the second through hole 112 are distributed along the extending direction of the first side surface 13. The first through hole 111 and the second through hole 112 are located above the first side surface 13. At this time, the first side surface 13 is the bottom surface of the first base 11. The third through hole 121 and the fourth through hole 122 are distributed along the extending direction of the third side surface 15. The third through hole 121 and the fourth through hole 122 are located above the third side surface 15. The third side surface 15 is the bottom surface of the second base 12.

[0040] The distances from the first through hole 111 and the second through hole 112 to the first side surface 13 are equal. Then, the distances from the third through hole 121 and the fourth through hole 122 to the third side surface 15 are equal. The distances from the first through hole 111 and the second through hole 112 to the first side surface 13 are equal to the distances from the third through hole 121 and the fourth through hole 122 to the third side surface 15. That is, the heights of the first through hole 111 and the second through hole 112 on the first base 11, and the third through hole 121 and the fourth through hole 122 on the second base 12 are of the same height.

[0041] The distance from the first through hole 111 to the second side surface 14 is equal to the distance from the third through hole 121 to the fourth side surface 16. The distance from the second through hole 112 to the second side surface 14 is equal to the distance from the fourth through hole 122 to the fourth side surface 16. The distance from the first through hole 111 to the second side surface 14 is greater than the distance from the second through hole 112 to the second side surface 14. The distance from the third through hole 121 to the fourth side surface 16 is greater than the distance from the fourth through hole 122 to the fourth side surface 16.

[0042] The distance between the first base 11 and the second base 12 is adjustable. According to the first furnace rib pipe 19 and the second furnace rib pipe 20 of different lengths, the distance between the first base 11 and the second base 12 is adjusted.

[0043] Both ends of the support rod 22 are respectively provided with a first groove 221 and a second groove 222 with arcs. The first groove 221 is used for clamping on the first furnace rib pipe 19, and the second groove 222 is used for clamping on the second furnace rib pipe 20 to prevent the support rod 22 from falling off the first furnace rib pipe 19 and the second furnace rib pipe 20.
