Description

technical field [0001] The invention belongs to the technical field of automatic welding equipment for long-distance pipelines, and in particular relates to a sectional clamping type all-position pipeline welding trolley traveling mechanism. Background technique [0002] With the development of pipeline construction in the direction of large diameter, large wall thickness and high steel grade, higher requirements are also placed on automatic pipeline welding equipment. Problems such as low welding efficiency, welding forming defects, and high labor intensity of workers have become the key factors restricting the cycle and quality of oil and gas engineering pipeline projects. Therefore, how to improve the quality and efficiency of pipeline welding construction, reduce the number of equipment components per unit operating surface, and improve single Device capability is the top priority. [0003] In the process of all-position pipeline welding, the welding trolley carries the...

Therefore, how to improve the quality and efficiency of pipeline welding construction, reduce the number of Equipment capability is the top priority

[0003] During the all-position pipeline welding process, the head of the welding trolley carries out circular motion on the guide rail laid on the pipeline to ensure a smooth transition of welding speed and cooperate with the head to complete welding processes such as heat welding, filling, and capping. In the existing technology, There are problems such as the large mass of the pipe welding trolley, inconvenient disassembly, uncontrollable clamping force of the driving wheel, damage to the guide rail, and wear of the driving wheel, which lead to welding torch deviation and trolley slipping during the welding process, which in turn leads to welding defects and affects In terms of welding quality and efficiency, there is an urgent need for a segmented clamping all-position pipe welding trolley traveling mechanism to solve the above problems
