A pipeline welding machine

Abstract

The invention discloses a pipeline internal welding machine, relates to the technical field of pipeline internal welding machine structure, and is mainly used to solve the problem that the existing internal welding machine cannot meet the requirement of smooth running of large-slope pipelines and has poor bending ability. Its main structure is: including a braking module, an internal welding machine energy module, a driving module and a welding machine module connected sequentially through a flexible connection mechanism; the braking module is connected with a camera module, and the welding machine module is connected with a control delivery module. module; the braking module and the driving module are provided with a self-centering mechanism, and the welding module is provided with an attitude adjustment mechanism. The invention provides a pipeline internal welding machine, which can adapt to the size of the internal diameter of the pipeline, so that the internal welding machine can run smoothly in the pipeline, and at the same time, it also has good bending ability.

Description

technical field [0001] The invention relates to the technical field of pipeline internal welding machine structure, in particular to an internal pipeline welding machine. Background technique [0002] In recent years, oil and gas pipelines at home and abroad have rapidly developed in the direction of high steel grade, high pressure, and large diameter. It is inevitable to promote pipeline automatic welding technology to improve pipeline welding quality and construction efficiency. At present, the automatic internal root welding of pipelines is mainly completed by pipeline internal welding machines. The pipeline internal welding machine is also called the pipeline internal circular seam automatic welding machine. During the pipeline welding process, it mainly completes the matching and inner root welding tasks of the two steel pipes to be welded. It is the key equipment in the pipeline welding construction. [0003] However, future pipeline construction cannot avoid laying i...

Problems solved by technology

However, the inner welding machine and the pipeline selected in this way will be in a relatively loose state

Especially when crawling and walking on a large slope, due to the gravity and slope, the existing internal welding machine is difficult to meet the requirements of the internal welding machine to walk smoothly on a large slope, and welding errors are prone to occur

[0005] 2. The bending capacity of the mainstream internal welding machines used in the construction of existing long-distance pipelines is mainly realized by reducing the mechanical structure size of the main engine. The bending capacity is low (> 40D), which is not suitable for pipeline laying. Root welding construction requires small curvature radius of the equipment's pipe bend
