Abstract

The invention discloses an auxiliary device for ship pipeline welding centering, and belongs to the technical field of pipeline welding equipment. The auxiliary device comprises a bent pipe part and astraight pipe part, wherein a first V-shaped support block and a second V-shaped support block are arranged at the bent pipe part in the pipeline direction; a third V-shaped support block and a fourth V-shaped support block are arranged at the straight pipe part in the pipeline direction, and are arranged oppositely at the equal height; the fourth V-shaped support block slides in the pipeline direction on a base. The invention also discloses a centering method for the straight pipe and the bent pipe by the auxiliary device for ship pipeline welding centering. The distance and angle between the four V-shaped support blocks are adjusted, so that straight pipes with certain length and bent pipes with different bending radii and bending angles can be centered and positioned. The auxiliary device has the advantages of low operation labor intensity, high centering efficiency and easy-to-control centering precision, and facilitates subsequent welding operation for operators.

Description

technical field [0001] The invention relates to the technical field of pipeline welding equipment, in particular to an auxiliary device and method for welding centering of ship pipelines. Background technique [0002] In the field of marine engineering and shipbuilding, pipelines are the main way of power transmission, transporting steam, water, oil, etc., so there is a large demand for pipelines, which requires high technical requirements for pipeline design, processing, and welding installation. Formed a system engineering. Among them, the two pipelines need to be centered during the butt welding process, and the efficiency and accuracy of the centering will affect the processing efficiency and service life of the pipeline. [0003] For example, the Chinese invention patent with the publication number CN108247280A discloses a pipe centering method. This centering method includes the splicing of the centering device, the setting of the initial value, the determination of ...
