Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing support tools, in particular to a processing support tool capable of leveling and moving pipelines. Background Art

[0002] The rotary stainless steel pipeline processing support tool is mainly applied to the welding process of large stainless steel pipelines. Traditional pipeline support tools such as bench vises are not applicable to the clamping of large pipelines due to their structural limitations.

[0003] Based on the above problems, the applicant proposed a rotary stainless steel pipeline processing support tool (the authorized announcement number is CN220260174U). As Figure 1 shown, this tool solves the problem of difficult support for large pipelines and adapts to pipelines with different diameters through an adjustable design.

[0004] However, the following problems were found during use:

[0005] ① During the process of supporting the pipeline for welding, the pipeline will have an axial offset, especially when the welding time is long. After long-term research, the reasons are as follows:

[0006] The pipeline is usually hoisted by a gantry crane and a sling and then placed on the turntable structure of the longitudinal rail structure. The hoisting position of the sling is generally where the worker binds it in the middle of the pipeline. However, after the pipeline is hoisted, the pipeline generally has a certain inclination angle, that is, it is difficult to be in a horizontal state. Therefore, when placing it on the longitudinal rail structure, usually the lower end of the pipeline first contacts the longitudinal rail structure, and then the whole pipeline is placed on the longitudinal rail structure. And because springs are installed on the cross rail structures on both sides of the longitudinal rail structure, the extrusion force of the end of the pipeline that first contacts the longitudinal rail structure on the spring is greater than that of the other end, that is, the two longitudinal rail structures are in a slightly inverted V shape, resulting in a slight deviation angle of the pipeline in the horizontal direction. When the longitudinal rail structure drives the pipeline to rotate, the pipeline will have an axial offset. Especially when welding a pipeline with a relatively thick wall thickness, due to the long welding time, the offset amount will affect the normal welding process.

[0007] ② During the welding process, the position of the whole tool is fixed, and the pipeline cannot move axially on the tool. Therefore, when welding a batch of pipelines, when the previous one is welded and the next pipeline is installed after the previous one is completed, since the gantry crane can only control the general position of the pipeline, the welding position of the welding machine and the pipeline cannot be well aligned. Each time, the position of the welding machine needs to be moved, and after moving the welding machine, the posture of the welding torch also needs to be adjusted, which is troublesome to operate.

[0034] It should be noted that the following detailed description is exemplary and is intended to provide further illustration of the present utility model. Unless otherwise specified, all technical and scientific terms used in the present utility model have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. In addition, it should also be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0035] In order to solve the problems of axial offset of the pipeline during the welding process and the trouble in adjusting the position of the welding machine during the batch welding process, this embodiment proposes a processing support tooling that can level and move the pipeline.

[0036] As Figure 2 shown, the processing support tooling that can level and move the pipeline in this embodiment includes a chassis 1, and a pair of longitudinal rail structures 2 are installed on the chassis 1. A plurality of support structures 3 are also installed on the chassis 1. Each support structure 3 is at the same height, the connection line of all support structures 3 is parallel to the axis of the longitudinal rail structure 2, and the distance from this connection line to the axes of the two longitudinal rail structures 2 is equal. As Figure 4 shown, the support structure 3 includes a support frame 32 and a first driving mechanism 31. The first driving mechanism 31 is used to drive the support frame 32 to lift and make the lifting distances of all support frames 32 equal to maintain the same height state. As Figure 5 shown, the support frame 32 is provided with rollers 34 arranged in a V shape. The axis of the roller 34 is perpendicular to the axis of the longitudinal rail structure 2, and the roller 34 is driven to rotate by a second driving mechanism 33.

[0037] The support structure 3 is added to this tooling on the original basis. The support structure 3 is located in the middle of the two longitudinal rail structures 2. All support structures 3 are at the same height and the connection line is parallel to the axis of the longitudinal rail structure 2. Before installing the pipeline, as Figure 6As shown, at this time, the support structure 3 is higher than the longitudinal rail structure 2. When installing the pipeline, first place the pipeline on the support structure 3. Under the action of the first driving mechanism 31, the support structure 3 descends (as Figure 7 shown), and the pipeline is placed horizontally on the longitudinal rail structure 2 in a state parallel to the axis of the longitudinal rail structure 2. In this way, the extrusion forces at both ends of the pipeline and the longitudinal rail structure 2 can be made the same, avoiding the problem that the axial deviation of the pipeline during long-term welding affects the welding, and improving the welding accuracy.

[0038] Before the support structure 3 descends, the second driving mechanism 33 drives the roller 34 to rotate, thereby axially moving the pipeline to align the weld displacement with the position of the welding torch. In this way, it is not necessary to move the welding machine for each welded pipeline, simplifying the adjustment process and improving the welding efficiency.

[0039] As Figure 3 、 Figure 4 shown, a hollow groove 11 is provided in the middle of the chassis 1. Installation frames 12 are provided at both ends of the hollow groove 11. The installation frames 12 extend towards the inside of the hollow groove 11, and the support structure 3 is installed on the installation frames 12. The installation frame 12 includes a vertical plate and a horizontal plate, and the vertical plate and the horizontal plate are perpendicular to form an L-shaped structure. The top of the vertical plate is connected to the bottom side of the chassis 1, and the outer end of the horizontal plate is connected to the bottom end of the vertical plate. The support structure 3 is installed on the horizontal plate. This L-shaped design provides good structural support, making the support structure 3 more stable and capable of bearing a large pipeline weight.

[0040] Reinforcing plates 13 are provided on the installation frame 12. The reinforcing plates 13 are triangular, with one right-angled side fitting against the vertical plate and the other right-angled side fitting against the horizontal plate. The setting of the reinforcing plates 13 increases the rigidity of the installation frame 12, avoids the deformation of the support structure 3 during use, and ensures the stable support of the pipeline.

[0041] The length of the horizontal right-angled side of the reinforcing plate 13 is less than the length of the horizontal plate, and the support structure 3 is installed at the inner end of the top surface of the horizontal plate. Through this design, on the premise of providing sufficient support and stability, the reinforcing plate 13 does not affect the installation of the support structure 3.

[0042] The first driving mechanism 31 is a hydraulic cylinder. The hydraulic cylinder includes a cylinder body and a piston rod. The cylinder body is fixed on the horizontal plate, and the support frame 32 is installed on the piston rod. The application of the hydraulic cylinder can achieve precise lifting adjustment of the support frame 32.

[0043] As Figure 5 shown, the support frame 32 includes a bottom plate and a support platform. The piston rod is connected to the middle of the bottom plate, and the support platform is located at both ends of the bottom plate. The support platform is a triangular platform, and the top surfaces of the two support platforms are V-shaped. This design enables the pipeline to be stably placed on the V-shaped support platform, increasing the stability and reliability of the support.

[0044] The top surface of the support platform is provided with support plates 35. The support plates 35 are located at both ends of the top surface of the support platform and are perpendicular to the top surface. The roller shaft 34 is rotatably installed between the two support plates 35. The arrangement of the support plates 35 provides a fixed installation position for the roller shaft 34, ensuring the smooth rotation of the roller shaft 34 and enabling effective support and movement of the pipeline.

[0045] The second driving mechanism 33 is a driving motor. The driving motor is installed on the outer side surface of the support plate 35 and is used to drive the roller shaft 34 to rotate. The application of the driving motor can realize the automatic rotation of the roller shaft 34, facilitating the movement and adjustment of the pipeline, with simple operation and improved work efficiency.

[0046] The roller shaft 34 is made of polyurethane material. The polyurethane material has good wear resistance and elasticity, can provide good shock absorption effect during the process of supporting and moving the pipeline, protect the surface of the pipeline from damage, and extend the service life of the roller shaft 34.

[0047] Although the specific implementation manners of the present invention are described above in conjunction with the accompanying drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the present invention.
