Description

Technical Field

[0001] The invention relates to the technical field of pipeline welding equipment, and in particular to a pipeline welding support tool. Background Art

[0002] The research shows that the effective support height of the medium diameter support tooling is between 250mm and 350mm. The support opening adopts a ￠42mm*4mm pipe, with a bending angle of 145 degrees and an oblique length of 150mm, which can meet the requirements of supporting pipes from ￠89mm to ￠168mm. The welding posture is relatively easy, the welding angle can be controlled between 60 degrees and 45 degrees, the weld is well formed, and the welding speed is fast.

[0003] The research aims at the effective support height of large diameter support tooling, which is between 150mm and 1100mm. The support opening adopts a pipe of ￠48mm*5mm, a length of 500mm, an oblique length of 100mm, and a bending angle of 60 degrees, which can meet the support of pipes of ￠219mm to ￠530mm. It meets the need for good support and prevention of rolling when welding large diameter workpieces, and meets the ability of rapid adjustment. The tooling is relatively light and convenient to move and adjust at any time.

[0004] In the pipe processing area of ​​the processing workshop, the workload of pipe welding is very large. Among them, medium and large diameter pipes are relatively large in volume and mass.

During the welding process, people are in a stiff and awkward posture, which leads to a decrease in welding quality and efficiency.

[0005] When turning over an irregular large diameter pipe, there is no suitable fixed support tooling. The usual practice is to weld round steel or steel pipes on the pipe for support, which are then cut off after completion, damaging the pipe surface. Summary of the invention
