[0004] However, due to the relatively large volume of petroleum and chemical pipelines, the relatively long length of long pipelines, and the relatively large volume and high height of circularizing machines; therefore, the ground clearance of the circularizing channel is relatively large. In the prior art, it is time-consuming and laborious for the operator to place the long pipeline into the moving mechanism, and there are certain safety hazards. At the same time, when the operator places the pipeline on the moving mechanism, since the pipeline to be circularized may still be relatively smooth, it is easy to roll, resulting in frequent position adjustment after being fed into the moving mechanism to ensure alignment with the circularizing channel of the circularizing machine; impurities may adhere to the surface of the pipeline during transportation, and during the circularizing process, the impurities will have rigid contact with the circularizing blocks on the circularizing machine, thus affecting the circularizing effect.

[0042] As Figure 3 and Figure 4 shown, the lifting unit further includes an oil storage cylinder 24 and two rectangular cylinders 18 respectively fixedly connected to the upper surface of the bottom plate 2. Communicating pipes 22 are fixedly communicated with the surfaces of the two rectangular cylinders 18. The opposite surfaces of the two communicating pipes 22 are respectively fixedly communicated with the two sides of the oil storage cylinder 24. Electric control valves 23 are fixedly installed on the surfaces of the two communicating pipes 22. The electric control valves 23 are prior art. It is through the connection of an electric actuator and a valve. After installation and debugging, the valve is driven by a power supply to realize the opening and closing actions of the valve, so as to achieve the purpose of switching or regulating the pipeline medium.

[0043] The inner bottom walls of the two rectangular cylinders 18 are fixedly connected with tension springs 20. The arrangement of the tension springs 20 can realize the reset of the rectangular lifting blocks 19. The inner walls of the two rectangular cylinders 18 are slidably connected with rectangular lifting blocks 19. The lower surfaces of the two rectangular lifting blocks 19 are respectively fixedly connected with the tops of the corresponding two tension springs 20. The upper surfaces of the two rectangular lifting blocks 19 are both fixedly connected with lifting arc-shaped blocks 21. There are two lifting arc-shaped blocks 21, which can be used as bearing components when lifting the pipeline body 7.

[0044] On the upper surface of the bottom plate 2, there is a grooved plate 14. The inner wall of the grooved plate 14 is slidably connected with a rectangular sliding plate 15. Through the grooved plate 14 and the rectangular sliding plate 15, after the electric control valve 23 is closed, the cylinder 11 can drive the limit contact head 12 to reset, and when the sliding vertical plate 8 resets, there will be no movement interference with the lifting arc-shaped block 21. One side of the rectangular sliding plate 15 is fixedly connected with two connecting bent rods 13. One ends of the two connecting bent rods 13 are respectively fixedly connected with the output ends of the cylinder 11. One side of the grooved plate 14 is fixedly connected with two connecting rods 52. The two connecting rods 52 are respectively fixedly connected with one side of the corresponding two rectangular lifting blocks 19. On the upper surface of the bottom plate 2, there is a limit groove 16. The inner wall of the limit groove 16 is slidably connected with two limit blocks 17. By setting the limit groove 16 and the limit blocks 17, the sliding stability of the sliding vertical plate 8 can be improved. The upper surfaces of the two limit blocks 17 are respectively fixedly connected with the lower surface of the sliding vertical plate 8.

[0045] As Figure 6 and Figure 10 As shown in [figures], the centering and moving unit further includes two fixing plates 25 fixedly connected to the lower surface of the second cross plate 5. There are two rectangular holes penetrating through the upper surface of the rectangular plate 26. The inner walls of the two rectangular holes are respectively fixedly connected with the surfaces of the corresponding two fixing plates 25. The opposite surfaces of the two fixing plates 25 are respectively rotatably connected to the two ends of the rotating sleeve 37. There is a chute 38 on the lower surface of the rectangular plate 26. The inner wall of the chute 38 is slidably connected with a slider 39. The lower surface of the slider 39 is fixedly connected with the upper surface of the first rack 28. Through the arrangement of the chute 38 and the slider 39, the movement stability of the first rack 28 can be improved.

[0046] Both the surfaces of the first clamping jaw 31 and the second clamping jaw 32 are fixedly connected with linkage rods 50. One ends of the two linkage rods 50 far away from the first clamping jaw 31 and the second clamping jaw 32 are fixedly connected with the same moving mechanism 51. The moving mechanism 51 is fixedly arranged below the first cross plate 4. The moving mechanism 51 is also composed of the same components as the first clamping jaw 31 and the second clamping jaw 32, and there are also conveying rollers 33 inside, which can improve the movement of the pipeline body 7 after being circularized and improve the movement effect. The clamping jaws of the moving mechanism 51 are synchronously moved with the first clamping jaw 31 and the second clamping jaw 32 through the linkage rods 50.

[0047] As Figure 8 andFigure 9 As shown in the figure, the cleaning unit includes a rotating seat 6 fixedly connected to the upper surface of the bottom plate 2. The upper surface of the rotating seat 6 is rotatably connected to a tooth ring cavity 41. The interior of the tooth ring cavity 41 is hollow and is set as an air cavity. A plurality of brush hairs 49 are fixedly connected to the inner wall of the tooth ring cavity 41. The brush hairs 49 are attached to the surface of the pipe body 7, and can brush the impurities on the surface of the pipe body 7. A plurality of through holes 47 are penetrated and opened on the inner wall of the tooth ring cavity 41. One side of the tooth ring cavity 41 is rotatably connected to a fixed ring 42. By means of the fixed ring 42 that rotates with the tooth ring cavity 41, it can be ensured that there will be no movement interference between the tooth ring cavity 41 and the air outlet pipe 43 when the tooth ring cavity 41 rotates.

[0048] The output end of the hydraulic cylinder 3 is fixedly connected with a second rack 40 and a piston rod 44 respectively through an extension rod. The second rack 40 meshes with the surface of the tooth ring cavity 41. The linkage between the second rack 40 and the hydraulic cylinder 3 can realize that when the hydraulic cylinder 3 drives the upper integral circular block to lift, the tooth ring cavity 41 rotates to clean the surface of the incoming pipe body 7. The surface of the piston rod 44 fits inside the cylinder 45, which can improve the airtightness. A cylinder 45 is fixedly connected to the inner wall of the first horizontal plate 4. The inner wall of the cylinder 45 is slidably connected to the surface of the piston rod 44 in a matching manner.

[0049] An air inlet pipe 46 and an air outlet pipe 43 are respectively fixedly communicated with the upper surface of the cylinder 45. One-way valves 48 are fixedly installed on the surfaces of the air inlet pipe 46 and the air outlet pipe 43. The one-way valve 48 is a prior art and will not be described in detail here. One end of the air outlet pipe 43 far from the cylinder 45 is fixedly communicated with one side of the fixed ring 42. The communication between the air outlet pipe 43 and the fixed ring 42 can realize that when the piston rod 44 rises, the gas inside the cylinder 45 is blown out through a plurality of through holes 47 opened inside the tooth ring cavity 41, improving the cleaning effect.

[0050] The specific working method is as follows: When in use, first place the pipe body 7 on the lifting arc-shaped block 21. Then, control the movement of the cylinder 11 through the controller on the integral circular machine body 1. The cylinder 11 rises, driving the limit contact head 12 to slide inside the long circular groove 9. During the sliding process, it can drive the sliding vertical plate 8 to slide inside the limit groove 16. When the cylinder 11 drives the sliding vertical plate 8 to slide, it will drive two rectangular lifting blocks 19 to rise through the connecting bent rod 13, thereby realizing the lifting of the pipe body 7. The sliding vertical plate 8 drives the first rack 28 to move, and further drives the rotation of the gear body 30. The rotation of the gear body 30 will drive the rotation of the first bevel gear 34. The rotation of the first bevel gear 34 can synchronously drive the second bevel gear 35 and the third bevel gear 36 to rotate in the opposite direction, so as to cooperate with the rotating sleeve 37 to drive the first jaw 31 and the second jaw 32 to open. After being fully opened, the pipe body 7 is lifted inside the first jaw 31 and the second jaw 32;

[0051] At this time, the limit contact head 12 presses one of the pressure sensors 10 at the highest point of the oval slot 9. The pressure sensor 10 can transmit the signal to the two electromagnetic control valves 23 through the controller, and close the electromagnetic control valves 23, so as to close the oil circuit inside the rectangular cylinder 18. Then, the air cylinder 11 descends, which can drive the limit contact head 12 to descend, thereby driving the sliding vertical plate 8 to reset. While the sliding vertical plate 8 resets, the first rack 28 resets and drives the gear body 30 to reverse, and then the centering clamping of the pipe body 7 between the first jaw 31 and the second jaw 32 can be realized. When the limit contact head 12 moves to the lowest point of the oval slot 9, it presses the other pressure sensor 10. The pressure sensor 10 can transmit the signal to the two electromagnetic control valves 23 through the controller, and open the electromagnetic control valves 23. At this time, the oil circuit is connected, and the two rectangular lifting blocks 19 can be reset under the reset of the tension spring 20, and the hydraulic oil inside the rectangular cylinder 18 is squeezed into the oil storage cylinder 24;

[0052] After the first jaw 31 and the second jaw 32 are reset and the pipe body 7 is centered and clamped, the pipe body 7 can be conveyed by the provided conveying rollers 33. While conveying, the hydraulic cylinder 3 ascends, which can drive the second rack 40 to move, and then drive the rotation of the tooth ring cavity 41, so that the bristles 49 inside the tooth ring cavity 41 can clean the impurities on the surface of the pipe body 7. While cleaning, the hydraulic cylinder 3 drives the piston rod 44 to ascend synchronously, and the air inside the cylinder 45 can be introduced into the tooth ring cavity 41 through the air outlet pipe 43 and blown out through the through holes 47, so as to realize blowing the surface impurities of the pipe body 7 and cleaning the bristles 49 at the same time. The pipe body 7 after cleaning the impurities can enter the roundness machine for rounding, and the rounded pipe body 7 can be assisted to move out through the moving mechanism 51, thus completing the rounding work.
