Description

Technical Field

[0001] The utility model relates to the technical field of welding debris cleaning, in particular to a pipeline outer wall debris treatment device for oil pipeline welding. Background Technique

[0002] An oil pipeline is a metal pipeline used for transporting oil. At the same time, oil pipelines are also connected together as a whole by welding multiple single pipelines. Oil pipeline welding is a process of connecting the two ends or pipe segments of a pipeline together, usually achieved through welding. Pipeline welding is a crucial link in the oil industry because it directly relates to the sealing, strength, and stability of the pipeline. After the oil pipeline is welded, debris will adhere to the surface of the pipeline. To avoid affecting subsequent anti-corrosion work, a debris treatment device is often used to clean the debris on the outer wall of the pipeline.

[0003] After retrieval, the Chinese patent document with the publication number CN213889384U discloses a pipeline outer wall debris treatment device for oil pipeline welding, including a housing. Two through holes are opened on the front surface of the housing, and the inner walls of the two through holes are rotatably connected with rotating shafts. Magnet wheels are fixedly connected to the outer surfaces of the two rotating shafts. A fixed square pipe is fixedly connected to the inner top wall of the housing, and a sliding square column is slidably connected to the inner wall of the fixed square pipe. The bottom end of the sliding square column is fixedly connected with a motor box, and a rotating motor is arranged inside the motor box. The output end of the rotating motor is fixedly connected with a wire wheel. For this pipeline outer wall debris treatment device for oil pipeline welding, by setting magnet wheels, a rotating motor, a rotating motor, a wire wheel, a compression spring, and a sliding square column, it is convenient to start the rotating motor and the rotating motor to move the device on the outer wall of the pipeline and clean the debris, which is convenient for grinding the pipeline and effectively improves the operation efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0030] Referring to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a device for processing debris on the outer wall of an oil pipeline for welding the oil pipeline, including a bottom plate 1. A support assembly is arranged on the upper surface of the bottom plate 1. A motor 3 is arranged on the top of the bottom plate 1. The output end of the motor 3 is fixedly connected with a crank 4. A connecting rod 5 is rotatably connected to the side wall of the crank 4. A connecting rod 6 is rotatably connected to the side wall of the connecting rod 5. One end of the connecting rod 6 is fixedly connected with a conical cover 7. A roller bead 8 is arranged inside the conical cover 7. A fixing bolt 9 is fixedly connected to the side wall of the roller bead 8. A sleeve one 10 is arranged on the side wall of the fixing bolt 9. A sleeve two 11 is arranged on the lower surface of the sleeve one 10. Grinding plates 13 are fixedly connected to the inner side walls of both the sleeve one 10 and the sleeve two 11. The support assembly includes a support rod 2. The lower surface of the support rod 2 is fixedly connected to the upper surface of the bottom plate 1. The upper surface of the support rod 2 is fixedly connected to the side wall of the motor 3.

[0031] When the sleeve one 10 and the sleeve two 11 are fixed on the pipeline, the motor 3 is started to drive the crank 4 to rotate. During this process, the connecting rod 5 will also rotate accordingly. During the rotation of the connecting rod 5, the conical cover 7 is pushed to move through the connecting rod 6. During the circular motion of the connecting rod 5, the fixing bolt 9 will deflect inside the conical cover 7 through the roller bead 8, so that the sleeve one 10 and the sleeve two 11 can reciprocate on the outer wall of the pipeline. And through the grinding plates 13, the debris on the outer wall of the oil pipeline is ground.

[0032] Referring to Figure 3 , a connecting pipe 14 is fixedly connected to the side wall of the sleeve one 10. A bolt sleeve 15 is rotatably connected to the side wall of the connecting pipe 14. The inner side wall of the bolt sleeve 15 is threadedly connected to the side wall of the fixing bolt 9. The sleeve one 10 is connected to the fixing bolt 9 through the bolt sleeve 15. A hinge 12 is fixedly connected to the side wall of the sleeve one 10. The sleeve one 10 and the sleeve two 11 are connected through the hinge 12. Inclined surfaces 21 are arranged inside both the sleeve one 10 and the sleeve two 11. Extension plates 16 are fixedly connected to the side walls of both the sleeve one 10 and the sleeve two 11. A fixing bolt 17 is arranged inside the extension plate 16. The fixing bolt 17 penetrates through the side wall of the extension plate 16 and extends to the bottom. A nut 18 is threadedly connected to the side wall of the fixing bolt 17. A counterweight 19 is fixedly connected to the upper surface of the bottom plate 1. Universal wheels 20 are arranged on the lower surface of the bottom plate 1.

[0033] When it is necessary to grind pipes of different diameters, the bolt sleeve 15 can be rotated to separate it from the fixing bolt 9. This step is to facilitate the replacement of the first sleeve 10 and the second sleeve 11, and select a suitable sleeve for installation. Next, install the first sleeve 10 and the second sleeve 11 that match the diameter of the pipe. During the installation process, rotate the bolt sleeve 15 connected to the side wall of the replaced first sleeve 10 to the outer wall of the fixing bolt 9 for fixation. This step is to ensure the stability and safety of the sleeve and avoid accidents during the grinding process. After completing the above steps, the grinding work can be carried out.

[0034] Working principle: When using this device to clean debris at the welding joint of an oil pipeline, push the bottom plate 1 to a suitable working position, then put the first sleeve 10 and the second sleeve 11 on the outer wall of the pipeline, make the extension plates 16 on both sides fit together, and fix them with the cooperation of the fixing bolt 17 and the nut 18. At this time, start the motor 3 to drive the crank 4 to rotate, thereby driving the connecting rod 5 to rotate. When the connecting rod 5 rotates, it pushes the conical cover 7 to move through the connecting rod 6. When the connecting rod 5 makes a circular motion, the fixing bolt 9 will deflect inside the conical cover 7 through the roller 8, and make the first sleeve 10 and the second sleeve 11 reciprocate on the outer wall of the pipeline, and grind the debris on the outer wall through the grinding plate 13. When it is necessary to grind pipes of different diameters, the bolt sleeve 15 can be rotated to separate it from the fixing bolt 9, replace the first sleeve 10 and the second sleeve 11, install the first sleeve 10 and the second sleeve 11 that match the diameter of the pipe, and rotate the bolt sleeve 15 connected to the side wall of the replaced first sleeve 10 to the outer wall of the fixing bolt 9 for fixation during installation, then the grinding work can continue. The debris generated by grinding will be discharged along the inclined plane 21.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
