Description

Technical Field

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

[0002] The pipeline rust removal device is a mechanical device specially used to remove rust, oxide layer, dirt and other attachments on 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 drive assembly and a limit assembly, the drive assembly is arranged above the limit assembly, the above scheme is provided with an angle adjustment mechanism, which can adjust the inclination angle of the pipeline placement seat, thereby facilitating rust removal of the pipeline in different environments, and at the same time, the activation of the hydraulic cylinder can drive the pipeline placement seat and the horizontal through groove to move horizontally, thereby achieving rust removal on the outer wall of the pipeline. However, the above scheme still has the following shortcomings when used in practice:

[0004] 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 rust removal wheel needs to be replaced manually. First, frequent manual operation will lead to interruption of the operation process 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 operator fatigue or technical differences, resulting in uneven grinding of the pipeline surface, which in turn affects 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. 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.

[0005] Therefore, it is necessary to design a pipeline rust removal device with auxiliary treatment to solve the above problems. Summary of the Invention

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

[0022] 2. Multiple rust removal wheels are compactly arranged along the circumference on the turning frame, and a rotary switching mechanism is used instead of a linear arrangement, which significantly reduces the overall size and lateral footprint of the device, making the equipment structure more compact, especially suitable for working environments with limited space;

[0023] 3. The elastic force of spring three is used to drive the inner rod to drive the rubber damping plate to continuously press the damping wheel made of the same material. The high friction generated between the matching arc surfaces of the two forms reliable damping, ensuring that the shaft only overcomes resistance and rotates when the rack drives the second gear, and remains absolutely stationary in the non-driven state. This design not only eliminates the risk of accidental deviation of the rust removal wheel during operation, allowing grinding wheels of different mesh sizes to be accurately positioned to the working position, but also reduces mechanical vibration and wear through the flexible contact of the rubber material.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figures 1-9 , a pipeline rust removal device for auxiliary treatment, including a base plate 1, a moving assembly is provided on the base plate 1, the moving assembly includes a linear actuator 21, a cross 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 base plate 1, and a slidable linear slide 22 is provided on the linear actuator 21. The specific structure and working principle of the linear actuator 21 and the linear slide 22 are prior art, which are not shown in the figure and will not be described in detail here. The cross plate 23 is connected to the linear slide 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 mounted on the two moving seats 24, and the two electric push cylinders 25 are arranged opposite each other, and the two clamping heads 26 are respectively fixed at the telescopic ends of the two electric push cylinders 25, the clamping heads 26 are truncated cone-shaped structures, and the outer surface of the clamping heads 26 is provided with anti-slip grooves, the first motor 27 is installed on one of the moving seats 24, and the output shaft of the first motor 27 is connected to the corresponding electric push cylinder 25 through transmission. The transmission structure between the two is the existing technology and will not be described in detail here.

[0036] Before rust removal, the staff will place the pipe to be rusted between the two clamping heads 26, and then start 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 clamp the pipe together to achieve the fixation of the pipe. Figure 1 As shown, the clamping head 26 has a truncated cone-shaped structure, which enables the two clamping heads 26 to fix pipes of different diameters, thereby expanding the scope of application of the device. After fixing the pipe, 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 is running, 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, so that the two clamping heads 26 jointly drive the pipe to rotate along its axis, so as to facilitate the subsequent grinding and rust removal of the pipe.

[0037] A fixing frame 31 is fixed to the side of the base plate 1, and a lifting cylinder 32 is installed on the fixing frame 31. A lifting frame 33 is fixed to the telescopic end of the lifting cylinder 32, and a rust removal component is provided on the lifting frame 33. The rust removal component includes a flip frame 41, and a rotating shaft 42 is fixed to one end of the flip frame 41. The end of the rotating shaft 42 away from the flip frame 41 is rotatably mounted on the lifting frame 33. The lifting frame 33 and the flip frame 41 are both U-shaped structures. The rust removal component also includes a second motor 43, a first rotating frame 44, a ring gear 45, a plurality of first gears 46, a plurality of rust removal wheels 47 and a second rotating frame 48. The second motor 43 is mounted on the flip frame 41 through a bracket. The first rotating frame 44 is fixed to the output end of the second motor 43. The ring gear 45 and The first rotating frame 44 is connected, and a plurality of first gears 46 are arranged inside the ring gear 45. Each first gear 46 is meshed with the ring gear 45. The second rotating frame 48 is rotatably mounted on the flip frame 41. A plurality of rust removal wheels 47 are arranged between the first rotating frame 44 and the second rotating frame 48. The plurality of rust removal wheels 47 are distributed in a circumferential array. The mesh number of each rust removal wheel 47 is different. The plurality of first gears 46 are respectively connected to the plurality of rust removal wheels 47. A rotating rod 34 is rotatably provided on the side of the lifting frame 33. A rotating plate 35 is fixed at the end position 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 ring gear 45 are coaxially arranged.

[0038] After completing the fixation of the pipeline, the staff controls the lifting cylinder 32 so that the lifting cylinder 32 drives the lifting frame 33 to move up and down, thereby moving the several rust removal wheels 47 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 pipeline. For the rust removal component, the staff starts the second motor 43. When the second motor 43 is running, it drives the first rotating frame 44 to rotate, and the ring gear 45 connected to the first rotating frame 44 rotates accordingly. During the rotation, the ring gear 45 can drive the several first gears 46 to rotate, so that the several rust removal wheels 47 rotate synchronously. In the initial state, the pipeline is located on one side of the several rust removal wheels 47. When the pipeline is rusted, the staff starts the linear actuator 21. When the linear actuator 21 is running, it drives the linear slide 22 to move. Figure 1 As shown, the linear slide 22 will drive the horizontal 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 along its axis, it can also move with the two moving seats 24. During the movement of the pipe, the rust removal wheel 47 with the smallest mesh number will connect with the outer surface of the pipe and grind and remove rust from the pipe.

[0039] The lifting frame 33 is provided with a rotating unit, which is used to drive the flip 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, and the rack 58 is arranged opposite the second gear 51. The rack 58 is connected to the lifting frame 33 through a connecting component. The connecting component includes a sealing cylinder 52, a sliding plug 53, a connecting rod 55, a frame 56 and a magnetic slide 57. The sealing cylinder 52 is fixed to the side of the lifting frame 33, and the sliding plug 53 is sealingly slidably connected to the inside of the sealing cylinder 52, and the sliding plug 53 and the sealing cylinder are connected. 1 and 1 are connected by a spring 1 54. One end of a connecting rod 1 55 is fixedly connected to a sliding plug 1 53. The other end of the connecting rod 1 55 extends to the outside of the sealing cylinder 1 52 and is fixedly connected to a frame 56. A magnetic slide 57 is slidably arranged on the frame 56, and the bottom end of the magnetic slide 57 is fixedly connected to a rack 58. A limit block 59 is fixed to the top of the magnetic slide 57. The inner ring of the frame 56 and the side surface of the magnetic slide 57 fit together. The cross-sections of the frame 56 and the magnetic slide 57 are both rectangular structures. The magnetic slide 57 is made of magnetic material.

[0040] A control assembly is provided on the flip frame 41. The control assembly includes a fixed plate 61, a guide rail 62, and a magnet 63. The fixed plate 61 is fixed to the side of the lifting frame 33, and the guide rail 62 is fixed to the bottom surface of the fixed plate 61. The magnet 63 is slidably provided on the guide rail 62. The magnet 63 and the guide rail 62 are connected by a tension spring 64, which is used to reset the magnet 63.

[0041] A damping assembly is provided on the fixed plate 61, comprising an outer cylinder 71, an inner rod 72, a damping plate 74, and a damping wheel 75. The outer cylinder 71 is fixed to the bottom surface of the fixed plate 61, and the inner rod 72 is slidably disposed 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 the damping wheel 75 is arranged directly opposite the damping plate 74. The outer cylinder 71 and the inner rod 72 are connected by a spring 73.

[0042] It is worth mentioning that a damping component for the rotating shaft 42 is provided on the fixed plate 61. By providing the damping component, a damping effect can be provided to the rotating shaft 42 and the flip frame 41. The rotating shaft 42 and the flip frame 41 will rotate only when the rack 58 drives the second gear 51 to rotate. In other cases, the flip 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 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 spring three 73, the inner rod 72 and the damping plate 74 always have a tendency to move downward, which enables the damping plate 74 to always press the damping wheel 75. Figure 7 As shown, the damping plate 74 and the damping wheel 75 are both made of rubber material, and the damping plate 74 is provided with an arc surface adapted to the damping wheel 75, so that there is a sufficiently large friction between the damping plate 74 and the damping wheel 75, and the friction provides a damping effect for the rotating shaft 42 and the flip frame 41;

[0043] Both ends of the bottom plate 1 are provided with a trigger assembly, which includes a side plate 81, a sealing cylinder 82, a sliding plug 83, a connecting rod 85 and a connecting pipe 86. The side plate 81 is fixed to the end position of the bottom plate 1, the sealing cylinder 82 is fixed to the side of the side plate 81, the sliding plug 83 is sealingly and slidingly connected to the inside of the sealing cylinder 82, and the sliding plug 83 and the sealing cylinder 82 are connected by a spring 84. One end of the connecting rod 85 is fixedly connected to the sliding plug 83, and the other end of the connecting rod 85 extends to the outside of the sealing cylinder 82. One end of the connecting pipe 86 is connected to the sealing cylinder 82, and the other end of the connecting pipe 86 is connected to the sealing cylinder 52.

[0044] When the pipe moves to the end position of the bottom plate 1, one of the moving seats 24 will squeeze the connecting rod 2 85 located at the end position. When the connecting rod 2 85 is squeezed, the connecting rod 2 85 will drive the corresponding sliding plug 2 83 to move. During the movement of the sliding plug 2 83, the air between it and the sealing cylinder 2 82 can be pressed into the interior of the sealing cylinder 1 52 through the connecting pipe 86. When the air enters the interior of the sealing cylinder 1 52, the gas will push the sliding plug 1 53 to move, so that the sliding plug 1 53 drives the connecting rod 1 55 to move. Figures 4 to 7As shown, the connecting rod 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 does not generate magnetic attraction to the magnetic slide 57. The magnetic slide 57 is in the lower limit position under the action of its own weight. At this time, the limit block 59 is placed at the top of the frame 56 to provide a limit for the magnetic slide 57. In this state, the rack 58 is set opposite the second gear 51. In the process of the connecting rod 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 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 action of 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 up, the rack 58 moves up accordingly.

[0045] Furthermore, when the pipe moves to the end position of the base plate 1, the linear slide 22 drives the pipe to move in the opposite direction, so that the pipe moves toward the other end of the base 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, which makes the sliding plug 1 53 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 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 when resetting, and will not drive the second gear 51 to rotate. During the resetting process of the rack 58, the magnet 63 will first move to the limit position. When the magnet 63 cannot move, the magnetic slide 57 will separate from the magnet 63. When the two are separated, the magnet 63 no longer attracts the magnetic slide 57, causing the magnetic slide 57 and the rack 58 to 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 magnet 63 will also automatically reset under the action of the tension spring 64.

[0046] 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. When the rust removal wheel 47 with the smallest mesh number completes the grinding of the pipeline, the turning frame 41 and several rust removal wheels 47 automatically rotate, 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 turn, so that the rust removal wheels 47 of each mesh number complete the grinding and rust removal work of the pipeline. The entire adjustment process does not require manual intervention, and automatic adjustment is achieved by using a mechanical structure. In addition, by setting circumferentially distributed rust removal wheels 47, the traditional rust removal structure arranged in a line is replaced, which greatly reduces the overall size and occupied area of the device.

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
