Description

Technical Field

[0001] The invention relates to the technical field of pipeline rust removal, and in particular to a pipeline rust removal device for auxiliary treatment. Background Art

[0002] The pipeline rust removal device is a mechanical equipment specially used to remove rust, oxide layer, dirt and other attachments from the inner and outer surfaces of pipelines. The device removes rust from the pipeline by grinding away the rust layer.

[0003] After searching, the Chinese patent with publication number CN112157556A discloses a rust removal device for water conservancy pipelines, including a support plate and a base, the support plate is fixedly installed on the upper part of the base, an angle adjustment mechanism is provided on one side of the support plate, the angle adjustment mechanism is connected to the rust removal mechanism, the rust removal mechanism is installed on the rust removal mechanism mounting seat, the rust removal mechanism includes a driving component and a limiting component, the driving component is arranged above the limiting component, the above scheme is provided with an angle adjustment mechanism, the inclination angle of the pipeline placement seat can be adjusted, and the rust removal of the pipeline is convenient in different environments, and at the same time, the hydraulic cylinder is started to drive the pipeline placement seat and the horizontal through groove to move horizontally, thereby realizing the rust removal of the outer wall of the pipeline, but the above scheme still has the following shortcomings when it is actually used: In the process of removing rust from the outer surface of the pipeline, it is necessary to use rust removal wheels of different mesh sizes to grind and remove rust from the pipeline in turn. The above solution does not have the function of automatically adjusting the rust removal wheel, and the replacement of the rust removal wheel needs to be performed manually. First, frequent manual operation will cause the operation process to be interrupted and reduce the overall rust removal efficiency, especially when processing long distances or large quantities of pipelines. The impact is more significant. Secondly, manual replacement relies on skilled workers, which not only increases labor costs, but may also affect process consistency due to operational fatigue or technical differences, resulting in uneven grinding of the pipeline surface, thereby affecting subsequent anti-corrosion or coating effects. In addition, during the manual replacement process, workers need to come into close contact with rotating equipment, which poses a risk of mechanical injury. If the operation is not standardized, it may also cause equipment damage or safety accidents. When faced with different degrees of rust or pipeline materials, manual adjustment is difficult to respond quickly, which can easily cause excessive grinding to damage the pipe body or incomplete rust removal, increasing the probability of rework.

This structure not only effectively prevents reverse rotation through the misaligned design of the gear and rack, ensuring the stability and directionality of the rust-removing wheel switching, but also realizes the coherent execution of the multi-stage rust-removing process through mechanical automation, significantly improving the efficiency and precision of pipeline rust removal, while reducing the manual operation intensity and error risk.

Multiple rust-removing wheels are tightly arranged on the flipping frame along the circumferential direction, and the rotary switching mechanism is used to replace the linear arrangement method, significantly reducing the overall size and lateral occupied area of the device, making the equipment structure more compact, especially suitable for working environments with limited space. 3. The elastic force of spring three enables the inner rod to drive the rubber damping plate to continuously press the damping wheel of the same material tightly, and a reliable damping is formed through the high friction force generated between the matching arc surfaces of the two, ensuring that the rotating shaft only rotates against the resistance when the rack drives the second gear, and remains absolutely stationary in the non-driving state. This design not only eliminates the risk of accidental offset of the rust-removing wheel during the operation, enabling grinding wheels of different meshes to be accurately positioned to the working position, but also reduces mechanical vibration and wear through the flexible contact of the rubber material.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Refer to Figures 1 - 9 , a pipeline rust removal device for auxiliary treatment, including a bottom plate 1, a moving component is arranged on the bottom plate 1, the moving component includes a linear actuator 21, a horizontal plate 23, two moving seats 24, two electric push cylinders 25, two clamping heads 26 and a first motor 27. The linear actuator 21 is installed on the side of the bottom plate 1, and a slidable linear sliding seat 22 is arranged on the linear actuator 21. The specific structure and working principle of the linear actuator 21 and the linear sliding seat 22 are prior arts and are not shown in the figure and will not be elaborated here. The horizontal plate 23 is connected to the linear sliding seat 22. The two moving seats 24 are respectively fixed at both ends of the horizontal plate 23. The two electric push cylinders 25 are respectively rotatably installed on the two moving seats 24, and the two electric push cylinders 25 are arranged opposite to each other. The two clamping heads 26 are respectively fixed at the telescopic ends of the two electric push cylinders 25. The clamping head 26 has a frustum-shaped structure, and the outer surface of the clamping head 26 is provided with anti-slip lines. The first motor 27 is installed on one of the moving seats 24, and the output shaft of the first motor 27 is in transmission connection with the corresponding electric push cylinder 25. The transmission structure between the two is a prior art and will not be elaborated here; Before rust removal, the staff places the pipeline to be rust-removed between the two clamping heads 26, and then starts the two electric push cylinders 25, so that the two electric push cylinders 25 drive the two clamping heads 26 to move synchronously and approach each other until the two clamping heads 26 jointly clamp the pipeline to achieve the fixation of the pipeline, as Figure 1As shown, the clamping head 26 has a frustum-like structure, which enables the two clamping heads 26 to fix pipes with different pipe diameters, so as to expand the application range of the device. After the pipe is fixed, the staff starts the first motor 27. The output shaft of the first motor 27 is connected to the corresponding electric push cylinder 25 through a transmission belt. Therefore, when the first motor 27 operates, it can drive the corresponding electric push cylinder 25 to rotate, and the clamping head 26 connected to the electric push cylinder 25 will also rotate accordingly. This enables the two clamping heads 26 to jointly drive the pipe to rotate along its axis, so as to facilitate subsequent grinding and rust removal of the pipe. A fixing frame 31 is fixed to the side of the bottom plate 1. A lifting cylinder 32 is installed on the fixing frame 31. The telescopic end of the lifting cylinder 32 is fixed with a lifting frame 33. A rust removal component is arranged on the lifting frame 33. The rust removal component includes a flipping frame 41. One end of the flipping frame 41 is fixed with a rotating shaft 42. The end of the rotating shaft 42 away from the flipping frame 41 is rotatably installed on the lifting frame 33. Both the lifting frame 33 and the flipping frame 41 have a U-shaped structure. The rust removal component further includes a second motor 43, a first rotating frame 44, a gear ring 45, a number of first gears 46, a number of rust removal wheels 47 and a second rotating frame 48. The second motor 43 is installed on the flipping frame 41 through a bracket. The first rotating frame 44 is fixed to the output end of the second motor 43. The gear ring 45 is connected to the first rotating frame 44. A number of first gears 46 are arranged inside the gear ring 45. Each first gear 46 meshes with the gear ring 45. The second rotating frame 48 is rotatably installed on the flipping frame 41. A number of rust removal wheels 47 are arranged between the first rotating frame 44 and the second rotating frame 48. The number of rust removal wheels 47 is circumferentially arrayed. The mesh number of each rust removal wheel 47 is different. A number of first gears 46 are respectively connected to a number of rust removal wheels 47. A rotating rod 34 is rotatably arranged on the side of the lifting frame 33. A rotating plate 35 is fixed at the end of the rotating rod 34. The second motor 43 is fixedly connected to the rotating plate 35. The rotating rod 34, the output shaft of the second motor 43, the rotating shaft 42 and the gear ring 45 are coaxially arranged. After the pipe is fixed, the staff controls the lifting cylinder 32 to drive the lifting frame 33 to move up and down, so that a number of rust removal wheels 47 move up and down until the rust removal wheel 47 with the smallest mesh number moves to a position where it can contact the outer surface of the pipe. For the rust removal component, the staff starts the second motor 43. When the second motor 43 operates, it drives the first rotating frame 44 to rotate, and the gear ring 45 connected to the first rotating frame 44 rotates accordingly. During the rotation of the gear ring 45, it can drive a number of first gears 46 to rotate, so that a number of rust removal wheels 47 rotate synchronously. In the initial state, the pipe is located on one side of a number of rust removal wheels 47. When rust removal treatment is carried out on the pipe, the staff starts the linear actuator 21. When the linear actuator 21 operates, it drives the linear slide 22 to move, as Figure 1As shown, the linear slide 22 will drive the cross plate 23 and the two moving seats 24 to move, and finally the two electric push cylinders 25 will drive the pipe to move. Therefore, during the process of the pipe rotating around its axis, it can also move along with the two moving seats 24. During the movement of the pipe, the derusting wheel 47 with the smallest mesh number will be connected to the outer surface of the pipe and polish and derust the pipe; A rotating unit is arranged on the lifting frame 33. The rotating unit is used to drive the turning frame 41 to rotate. The rotating unit includes a second gear 51 and a rack 58. The second gear 51 is fixedly sleeved on the rotating shaft 42. The rack 58 is arranged opposite to the second gear 51. The rack 58 is connected to the lifting frame 33 through a connecting component. The connecting component includes a first sealing cylinder 52, a first sliding plug 53, a first connecting rod 55, a frame body 56 and a magnetic sliding plate 57. The first sealing cylinder 52 is fixed on the side surface of the lifting frame 33. The first sliding plug 53 is hermetically and slidably connected inside the first sealing cylinder 52, and the first sliding plug 53 is connected to the first sealing cylinder 52 through a first spring 54. One end of the first connecting rod 55 is fixedly connected to the first sliding plug 53. The other end of the first connecting rod 55 extends to the outside of the first sealing cylinder 52 and is fixedly connected to the frame body 56. The magnetic sliding plate 57 is slidably arranged on the frame body 56, and the bottom end of the magnetic sliding plate 57 is fixedly connected to the rack 58. A limiting block 59 is fixed at the top end of the magnetic sliding plate 57. The inner ring of the frame body 56 and the side surface of the magnetic sliding plate 57 are mutually attached. The cross sections of the frame body 56 and the magnetic sliding plate 57 are both rectangular structures. The magnetic sliding plate 57 is made of magnetic material; A control component is arranged on the turning frame 41. The control component includes a fixing plate 61, a guide rail 62 and a magnetic block 63. The fixing plate 61 is fixed on the side surface of the lifting frame 33. The guide rail 62 is fixed on the bottom surface of the fixing plate 61. The magnetic block 63 is slidably arranged on the guide rail 62. The magnetic block 63 is connected to the guide rail 62 through a tension spring 64. The tension spring 64 is used for the reset of the magnetic block 63; A damping component is arranged on the fixing plate 61. The damping component includes an outer cylinder 71, an inner rod 72, a damping plate 74 and a damping wheel 75. The outer cylinder 71 is fixed on the bottom surface of the fixing plate 61. The inner rod 72 is slidably arranged in the outer cylinder 71. The bottom end of the inner rod 72 extends to the outside of the outer cylinder 71 and is fixedly connected to the damping plate 74. The damping wheel 75 is fixedly sleeved on the rotating shaft 42 and is arranged opposite to the damping plate 74. The outer cylinder 71 and the inner rod 72 are connected through a third spring 73; It is worth mentioning that a damping component for the rotating shaft 42 is provided on the fixing plate 61. By setting the damping component, a damping effect can be provided for the rotating shaft 42 and the flipping frame 41. Only when the rack 58 drives the second gear 51 to rotate, the rotating shaft 42 and the flipping frame 41 will rotate. In other cases, the flipping frame 41 will remain stationary under the damping action of the damping component. This design can ensure the stability of the rust removal wheel 47 during the rust removal process, avoid the situation of position deviation of the rust removal wheel 47 during the rust removal process, and ensure the rust removal effect. Specifically, under the elastic force of the third spring 73, the inner rod 72 and the damping plate 74 always have a tendency to move downward, which makes the damping plate 74 always able to press tightly against the damping wheel 75, as Figure 7 shown. Both the damping plate 74 and the damping wheel 75 are made of rubber material, and an arc surface adapted to the damping wheel 75 is provided on the damping plate 74, which makes the friction force between the damping plate 74 and the damping wheel 75 large enough, and this friction force provides a damping effect for the rotating shaft 42 and the flipping frame 41; Trigger components are provided at both ends of the bottom plate 1. The trigger components include side plates 81, second sealing cylinders 82, second sliding plugs 83, second connecting rods 85 and connecting pipes 86. The side plates 81 are fixed at the end positions of the bottom plate 1, the second sealing cylinders 82 are fixed on the sides of the side plates 81, the second sliding plugs 83 are hermetically slidably connected inside the second sealing cylinders 82, and the second sliding plugs 83 and the second sealing cylinders 82 are connected by a second spring 84. One end of the second connecting rod 85 is fixedly connected to the second sliding plug 83, and the other end of the second connecting rod 85 extends outside the second sealing cylinder 82. One end of the connecting pipe 86 is communicated with the second sealing cylinder 82, and the other end of the connecting pipe 86 is communicated with the first sealing cylinder 52; When the pipeline moves to the end position of the bottom plate 1, one of the moving seats 24 will squeeze the second connecting rod 85 located at this end position. When the second connecting rod 85 is squeezed, the second connecting rod 85 will drive the corresponding second sliding plug 83 to move. During the movement of the second sliding plug 83, the air between it and the second sealing cylinder 82 can be pressed into the inside of the first sealing cylinder 52 through the connecting pipe 86. When the air enters the inside of the first sealing cylinder 52, the gas will push the first sliding plug 53 to move, so that the first sliding plug 53 drives the first connecting rod 55 to move, as Figures 4 - 7As shown, the connecting rod 1 55 will drive the frame 56 to move when it moves. In the initial state, the magnetic slide 57 is located at a position away from the magnetic block 63. At this time, the magnetic block 63 will not generate magnetic attraction to the magnetic slide 57. The magnetic slide 57 is located at the lower limit position under its own weight. At this time, the limit block 59 is placed on the top of the frame 56 to provide a limit for the magnetic slide 57. In this state, the rack 58 is set opposite to the second gear 51. In the process of the connecting rod 1 55 driving the frame 56 to move, the magnetic slide 57 and the rack 58 will also move accordingly. In this process, the rack 58 will mesh with the second gear 51 and drive the second gear 51 to rotate. When the connecting rod 1 55 moves to the limit position, the magnetic slide 57 just moves to the bottom of the positive magnetic block 63. At this time, under the magnetic attraction of the magnetic block 63, the magnetic slide 57 will move upward and be adsorbed on the magnetic block 63. When the magnetic slide 57 moves upward, the rack 58 moves upward accordingly. Furthermore, when the pipeline moves to the end position of the bottom plate 1, the linear slide 22 drives the pipeline to move in the opposite direction, so that the pipeline moves toward the other end of the bottom plate 1. This action will separate the moving seat 24 and the connecting rod 2 85 in the extruded state from each other. When the two are separated, the sliding plug 2 83 will be reset under the action of the corresponding spring 2 84. When the sliding plug 2 83 is reset, it can extract the gas in the sealing cylinder 1 52 through the connecting pipe 86, so that the sliding plug 1 53 is also reset under the action of the spring 1 54. When the sliding plug 1 53 is reset, the connecting rod 1 55, the frame 56, the magnetic slide 57 and the rack 58 are also reset. Since the magnetic slide 57 has been adsorbed on the magnetic block 63, the gear rack 58 is reset. The rack 58 will remain staggered with the second gear 51 during the resetting process. With this design, the rack 58 will not mesh with the second gear 51 during the resetting process, and will not drive the second gear 51 to rotate. During the resetting process of the rack 58, the magnetic block 63 will first move to the limit position. When the magnetic block 63 cannot move, the magnetic slide 57 will separate from the magnetic block 63. When the two are separated, the magnetic block 63 no longer attracts the magnetic slide 57, so that the magnetic slide 57 and the rack 58 move down again. At this time, the rack 58 is already on one side of the second gear 51, so that the rack 58 can drive the second gear 51 to rotate. In addition, the magnetic block 63 will also automatically reset under the action of the tension spring 64. Based on the above process, whenever the pipe moves to the end position of the bottom plate 1, the connecting seat can drive the trigger assembly to operate, so that the rack 58 drives the second gear 51 to rotate. Whenever the trigger assembly and the connecting assembly are reset, the rack 58 will be staggered with the second gear 51. Therefore, under the driving action of the rack 58, the second gear 51 will periodically rotate in one direction and will not rotate in the opposite direction. When the second gear 51 rotates, it will drive the rotating shaft 42 to rotate, so that the flip frame 41 rotates accordingly. Figure 2 and Figure 3As shown, whenever the second gear 51 rotates, the turning frame 41 can rotate a certain rust removal wheel 47 to a position facing the pipeline. Through this design, the function of automatically replacing the rust removal wheel 47 is realized. After the rust removal wheel 47 with the smallest mesh number finishes grinding the pipeline, the turning frame 41 and several rust removal wheels 47 rotate automatically, so that the rust removal wheel 47 with a slightly larger mesh number moves to the working position and completes the subsequent grinding and rust removal of the pipeline. Similarly, during the entire rust removal process, several rust removal wheels 47 rotate in sequence, so that the rust removal wheels 47 of each mesh number all complete the grinding and rust removal work of the pipeline. The entire adjustment process does not require manual intervention and realizes automatic adjustment by using a mechanical structure. In addition, by setting the circumferentially distributed rust removal wheels 47, the traditional rust removal structure arranged in a straight line is replaced, greatly reducing the overall size and occupied area of the device.

[0021] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
