Description

Technical Field

[0001] This utility model relates to the field of pipeline end beveling technology, and in particular to an internally centered self-propelled pipeline beveling processing device. Background Technology

[0002] Pipelines are used to transport oil, gas, or water extracted from the ground to oil and gas industrial enterprises. Pipelines include both seamless and welded pipes, with ends that can be flat, threaded, or socketed. Connection methods include end welding, coupling, and socket connection, with welding being the most common. Welded pipelines undergo end beveling at the factory before leaving the factory.

[0003] When pipelines are damaged due to improper transportation or need to be temporarily adjusted in length, the beveling is reprocessed. Workers will temporarily prepare various welding and cutting auxiliary tools according to different pipe diameters and use the auxiliary tools to position the pipeline.

[0004] The existing technology has the following drawbacks: In the traditional pipeline welding construction stage, when there is beveling damage or the pipeline length needs to be adjusted for process reasons, temporary beveling is required. This can be done manually or with temporary tooling, but both methods suffer from unstable beveling quality and poor tooling compatibility. In addition, the existing auxiliary tooling cannot be adapted to pipes of different diameters. Therefore, an internally centered self-propelled pipeline beveling device is proposed to solve the above problems. Utility Model Content

A long rod 5 is fixedly connected to the left side wall of the support plate 2, and a movable block 7 is slidably connected through and slidably connected to the outer wall of the long rod 5. The movable block 7 has a slot corresponding to the long rod 5, allowing the movable block 7 to... The long rod 5 is fixedly connected to a fixed block 6 on its outer wall. The left end of the long rod 5 is fixedly connected to a connecting plate 12. The left side wall of the connecting plate 12 is fixedly connected to a rectangular block 13. The connecting plate 12 provides a connection and support for the rectangular block 13. An adjustment component is provided on the right side wall of the support plate 2. The top of the movable block 7 is provided with a movable mechanism, which includes a hinge rod 8. The hinge rod 8 is hinged to the top of the movable block 7. The outer wall of the hinge rod 8 is hinged to a rotating rod 9 through a hinge column 10. Since the length of the hinge rod 8 is fixed, when one end of the movable block 7 moves to the right with one end of the hinge rod 8, the other end of the hinge rod 8 will deflect upward with one end of the rotating rod 9. When one end of the movable block 7 moves to the left with one end of the hinge rod 8, the other end of the hinge rod 8 will deflect downward with one end of the rotating rod 9. A top block 16 is rotatably connected to the outside of the hinge column 10. The top block 16 contacts the inner wall of the pipe and provides a positioning function for the pipe.

[0034] Reference Figure 1 , Figure 4 and Figure 5The adjustment assembly includes a speed-regulating motor 3, which is fixedly connected to the right side wall of the support plate 2 via a bracket. A gear 14 is fixedly connected to the output end of the speed-regulating motor 3, and a transmission gear 15 meshes with the outer wall of the gear 14. Power is transmitted from the gear 14 to the transmission gear 15. A control frame 17 is fixedly connected to the right end of the transmission gear 15. The control frame 17 is existing technology; its height and position can be adjusted via external electrical control. An adjusting block 18 is provided on the outer wall of the control frame 17, and a bolt 19 is threadedly connected to the inner wall of the adjusting block 18. A matching bolt 19 is provided inside the adjusting block 18. The inner wall of the adjusting block 18 is rotatably connected to a clamp 20. The adjusting block 18 has a slot corresponding to the clamp 20 to facilitate the rotation of the clamp 20. The clamp 20 has multiple sets of circular holes. The clamp 20 can hold the corresponding processing tools according to the processing requirements. The front end of the bolt 19 is set as a smooth surface. The bolt 19 is inserted into the inner wall of the clamp 20. The smooth surface of the bolt 19 is initially inserted into the hole of the clamp 20. The transmission gear 15 is rotatably connected to the inner wall of the support plate 2. The transmission gear 15 is provided with a cylinder. The support plate 2 has a slot corresponding to the cylinder to facilitate the rotation of the transmission gear 15.

[0035] Reference Figures 1-3 The rotating rod 9 is hinged to the top of the fixed block 6, and the movable block 7 is fixedly connected to the outer wall of the slider 11. The slider 11 can move the movable block 7 back and forth. The threaded rod 4 is rotatably connected to the inner wall of the rectangular block 13. The rectangular block 13 has a slot corresponding to the threaded rod 4 to facilitate the rotation of the threaded rod 4. The outer side of the top block 16 is set as arc so that the top block 16 can better fit the inner wall of the pipe.

[0036] Working principle: When the opening degree of the device needs to be adjusted, turn on motor 21. Motor 21 will rotate the threaded rod 4 clockwise. At this time, the slider 11 on the threaded rod 4 will move the movable block 7 and the hinge rod 8 to the right. The other end of the hinge rod 8 will deflect one end of the rotating rod 9 upward. The upward deflection of the hinge rod 8 and the rotating rod 9 allows the device to adapt to pipes with larger diameters. At the same time, the hinge column 10 will move the top block 16 upward, fitting against the inner wall of the pipe to position the pipe. When the adjustment is complete, turn off motor 21. To reduce the opening degree of the device... When the opening degree is adjusted, turn on motor 21, causing motor 21 to rotate counterclockwise with threaded rod 4. At this time, slider 11 will move to the left, and slider 11 will move movable block 7 and hinge rod 8 to the left. The other end of hinge rod 8 will deflect one end of rotating rod 9 downwards. The downward deflection of hinge rod 8 and rotating rod 9 allows the device to be used with small-diameter pipes. Top block 16 will also fit against the inner wall of the pipe to position the pipe. When the adjustment is complete, turn off motor 21. If you need to adjust the opening degree of the device again, just repeat the above operation steps.

[0037] When the angle of clamp 20 needs to be adjusted, turn bolt 19 clockwise to separate the smooth surface of bolt 19 from the slot on clamp 20. Then, rotate clamp 20 by hand to adjust its angle. When the adjustment is complete, bolt 19 will coincide with the slot on clamp 20. Turn bolt 19 counterclockwise by hand to insert bolt 19 into the slot of clamp 20, thus limiting the clamp 20. If the angle of clamp 20 needs to be adjusted again, simply repeat the above steps.
