Description

Technical Field

[0001] The invention belongs to the technical field of pipeline welding, and specifically refers to welding equipment for a pipeline support of a water conservancy project. Background Art

[0002] Various pipes are widely used in water conservancy projects to collect, transport, distribute and regulate water resources. There are many ways to connect pipes, among which welding is one of the most common connection methods, which can provide a strong connection effect.

[0003] When welding pipes, it is crucial to ensure that the two pipes are in a coaxial position, which requires the two pipes to be aligned. However, the prior art cannot synchronize the two pipes while fixing them in the center. This requires workers to drill under the pipes for welding, which is inconvenient. In addition, during the welding process, the pipes on both sides need to be chamfered, and it is necessary to switch between the chamfering equipment and the welding equipment, resulting in low welding efficiency.

[0004] Therefore, there is a need for a welding device for a water conservancy project pipeline support to solve the technical problems in the prior art that two pipelines cannot be fixed and rotated synchronously at the same time and that the equipment needs to be replaced, resulting in low welding efficiency. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a welding device for a water conservancy project pipeline support. During the welding process, the force of the welding machine in the moving direction close to the pipelines on both sides is cleverly used to realize the flipping of the chamfering knife and the welding machine, thereby ensuring the independence and non-interference of the welding and chamfering operations, so that the work flow of chamfering first and then welding can be smoothly realized, and there is no need to replace the equipment during the welding process, which solves the technical problem of low welding efficiency caused by the need to replace the equipment in the prior art. The chamfering knife is driven by high-pressure airflow to chamfer the pipelines on both sides. The high-pressure airflow not only cools the chamfering knife, but also effectively blows off the waste chips. After the welding is completed, the high-pressure airflow drives the chamfering knife to remove the burrs of the weld and cool the weld. The high-pressure airflow drives the fixed tooth columns on both sides to rotate. Through the tooth meshing method, the connecting tubes on both sides can rotate synchronously, thereby realizing the synchronous fixation and rotation of the pipelines on both sides. During the chamfering and welding process, the synchronization between the pipelines on both sides solves the technical problem that the two pipelines cannot be fixed and rotated synchronously at the same time in the prior art.
