Embodiment 1

[0051] Such as Figure 1-3 As shown in the figure, a liner inner matching mechanism is used for butt jointing of the inner interface of the pipeline, and accepts molten iron welded at the gap between the liner and the inner wall of the pipeline inner interface. The inner matching mechanism of the liner includes:

[0052] Rotary mechanism 1 that provides rotational driving force for the mating mechanism in the liner;

[0053] Specifically, the rotating mechanism 1 can be directly driven by a motor, or can be driven by an internal gear driven by a motor. At the same time, the rotating mechanism 1 can have a reverse rotating drive mechanism, such as a motor with a reverse function, so as to realize rotation. Pause and / or forward and reverse rotation of mechanism 1.

[0054] In this embodiment, the rotary mechanism 1 is driven by an internal gear driven by a motor as an example, as figure 2 As shown, specifically, the rotating mechanism 1 includes a rotating ring 101 and a driv...

Embodiment 2

[0082] A pipe liner inner mouthpiece system, comprising a traveling mechanism, a positioning mechanism, a tensioning mechanism and a liner inner mouthpiece mechanism described in Embodiment 1 above.

Embodiment 3

[0084] A pipeline welding method that can be followed synchronously, the method comprising:

[0085] S1, a kind of pipe liner inner counterpart system in embodiment 2 is placed in the pipe;

[0086] S2. Move and position the system to the position to be welded through the traveling mechanism and the positioning mechanism;

[0087] S3. Complete the assembly of the pipelines through the tensioning mechanism;

[0088] S4, the ceramic liner 2022 on the outer peripheral surface of the rotating ring 101 is completely attached to the groove of the inner wall of the pipeline through the movement of the steering gear 201;

[0089] Wherein, the movement of the steering gear 201 is that the rotating rocker mechanism 2011 on the steering gear realizes the rotation, drives the other end of the flexible shrapnel 204 to move upwards, and then makes the liner mechanism 202 close to the inner wall of the pipeline until the ceramic liner 2022 is closely attached to the inner wall of the pipeli...

Abstract

The invention relates to a liner inner aligning mechanism, an aligning device system and a pipeline welding method thereof, and the liner inner aligning mechanism and pipeline outer welding equipment synchronously rotate by driving a rotating ring to rotate, so that a synchronous following effect is achieved. When the backing mechanism can be finely adjusted under the action of the flexible elastic piece, the backing mechanism is tightly attached to the welding seam so as to control the forming quality of the welding seam on the back face during backing welding, and the welding efficiency and the welding quality of backing welding are improved; through the arrangement of the ceramic layer, the problem that the mechanical property of a welding seam is affected due to the fact that copper permeates into the welding seam easily in the welding process of a traditional copper liner inner aligning device is solved, the ceramic layer does not make direct contact with steel pipes on the two sides of the welding seam, and the service life of the ceramic layer is guaranteed.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a liner inner counterpart mechanism, a counterpart system and a pipeline welding method thereof. Background technique [0002] Pipeline systems include long-distance large-diameter transmission pipelines and transmission pipelines for small-diameter processing systems such as plant sites. Compared with large-scale transmission pipelines, pipeline systems such as factory sites are different in that small-diameter pipelines have a high density, and there are many pipeline turning points and intersections, while large-scale pipelines are generally single pipelines with large diameters and long distances, which belong to large-scale Engineering work construction. [0003] At present, the material of pipelines mainly involves ordinary carbon steel, stainless steel or other types of metals, and the construction of pipeline systems usually includes connecting pipelines wi...
