[0002] Fluidized bed reactors are composed of pipes and headers. There are many holes on the headers. The pipes and holes are welded together. The joints of the headers and pipes are difficult to weld. They need to be welded thoroughly in all positions. In addition, the space is small. Nondestructive testing is also required immediately after welding. Only after passing the test can the next layer be assembled. When the pipes and headers are welded, the headers are bent outward due to welding stress. Therefore, a tooling that can prevent deformation of the pipes and headers during welding is very necessary.

[0006] When using, first connect the support seat to the I-beam through fasteners, then tilt the header from a vertical position to a horizontal position and support it on the support seat, then connect it to the I-beam with a stopper, tighten both ends of the header, and finally weld the pipes. The purpose of the support seat is to prevent the header from deforming downward when the pipes are welded to the header, and the purpose of the stopper is to prevent both ends of the header from moving upward when welding the pipes.
[0007] Further preferably, the limiting member comprises a U-shaped bolt and a nut with an opening facing downward, and the U-shaped bolt passes downward through the upper wing plate of the I-beam and is tightened and fixed by the nut.
[0008] Further preferably, the support seat includes a base and a support plate, the base is fixed to the upper wing plate of the I-beam by bolts, the support plate is two parallel plates with vertical plate surfaces and perpendicular to the direction of the I-beam web, and the support plate is fixed to the base.
[0009] Further preferably, a groove for placing the header is provided on the top of the support plate.
[0010] The utility model has the advantages of scientific tooling design, simple structure, time-saving and labor-saving, convenient operation and can effectively prevent deformation of the row pipes and the header during assembly welding. BRIEF DESCRIPTION OF THE DRAWINGS
