Some welding points require the posture of the inlet and outlet pipe assembly to be adjusted to an inclined position before welding, and the fixed parts of the inlet and outlet pipe assembly need to be replaced to achieve the purpose of adjusting the posture of the inlet and outlet pipe assembly, so that other welding points of the inlet and outlet pipe assembly become easy-to-weld points. The process requires constant adjustment, which is time-consuming and labor-intensive, and reduces work efficiency. After the welding of the inlet and outlet pipe support is completed, due to the use of multiple fixed parts, the inlet and outlet pipe assembly is easily blocked by the fixed parts during unloading.
