Description

Technical Field

[0001] This utility model relates to the field of pipeline corrosion protection technology, specifically a pretreatment device for pipeline corrosion protection. Background Technology

[0002] Most existing pipeline corrosion protection methods use coating corrosion protection, which involves uniformly and densely applying paint to the inner surface of the pipeline to isolate it from various corrosive media. However, in the process of corrosion protection treatment of the inner surface of the pipeline, it is necessary to treat the rust on the inner surface of the pipeline.

[0003] In the existing process of treating rust on the inner surface of pipes, grinding plates are usually used to grind the rust. However, when the inner surface of the pipe is severely damaged, a second grinding is required after the first grinding. Although two grindings can ensure the effect of treating the rust on the inner surface of the pipe, the two independent grindings will increase the complexity of the operation and the grinding time, thereby reducing the efficiency of the pretreatment of the inner surface of the pipe.

[0004] Therefore, there is an urgent need for a pretreatment device for pipeline corrosion prevention to solve the above problems. Utility Model Content

Each rotating plate has a spline hole, and each spline hole is matched with the spline plate. The processing tube is equipped with a telescopic assembly for extending and retracting the T-shaped rotating rod.

[0010] The telescopic assembly includes a spring, which is sleeved on the T-shaped rotating rod located on the outer side wall of the processing tube.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Please see Figures 1-3 The diagram shows a pretreatment device for pipeline corrosion protection, including a pipeline body 101 and a base plate 102. A support plate 105 is fixedly connected to the base plate 102, and a working plate 104 is slidably connected to the support plate 105. The base plate 102 is provided with a pushing cylinder 103 (the pushing cylinder 103 is model CGIBN20-120, which is prior art and will not be described in detail here) for pushing the working plate 104. It also includes a treatment component set on the working plate 104 for performing multi-stage grinding on the inner surface of the pipeline body 101 and a fixing component set on the base plate 102 for fixing the pipeline body 101.

[0021] The processing assembly includes a processing rod 201 rotatably connected to the side of the working plate 104 near the base plate 102. A processing tube 202 is fixedly connected to the end of the processing rod 201 away from the working plate 104. Multiple rotating plates 203 are rotatably connected to the processing tube 202. Multiple polishing plates 204 are slidably connected to the periphery of each rotating plate 203. Each polishing plate 204 is located outside the processing tube 202 and is arranged in a ring array. The processing tube 202 is provided with a driving assembly for driving each polishing plate 204. A rotating motor 205 (model Y80M1-2, which is prior art and will not be described in detail here) is provided on the side of the working plate 104 away from the base plate 102.

[0022] It should be noted that, through the configuration of the processing components, the spacing between each set of grinding plates 204 increases sequentially from the grinding direction under the combined action of the driving and rotating components. This achieves multi-stage grinding of the inner wall of the pipe body 101 without the need for multiple grinding operations. Thus, while ensuring the grinding effect on the inner wall of the pipe body 101, the complexity and grinding time of the grinding operation are reduced, thereby improving the efficiency of pre-treatment of the inner surface of the pipe.

[0023] Please see Figure 2 and Figure 3 The driving assembly shown in the figure includes a driving plate 301 slidably connected to the side wall of the processing tube 202. One end of the driving plate 301 is connected to the grinding plate 204. A connecting plate 302 is fixedly connected to the side wall of the driving plate 301 inside the processing tube 202. A spiral strip 303 is provided on the side of the rotating plate 203 near the driving plate 301. The end of the connecting plate 302 away from the driving plate 301 is slidably connected to the spiral strip 303.

[0024] It should be noted here that the spacing between each grinding plate 204 is adjusted through the settings of the drive component.

[0025] Please see Figure 2 and Figure 3 The drive board 301 in the diagram has a square cross-section;

[0026] It should be noted here that the drive board 301 is set to a square shape to provide guidance and limit its movement.

[0027] Working principle: When the pipe body 101 needs to be pre-treated for corrosion protection, the pipe body 101 is first fixed by the fixing component (the bottom of the pipe body 101 is a certain distance from the base plate 102). Then, the spacing between each set of grinding plates 204 is adjusted according to the corrosion of the inner wall of the pipe body 101. During the adjustment process, the rotating component drives the rotating plate 203 to rotate, which in turn drives the spiral strip 303 to rotate. During the rotation of the spiral strip 303, the spiral transmission between the spiral strip 303 and each connecting plate 302 and the guiding action of each driving plate 301 push each grinding plate 204 to move closer or further away from each other, thereby realizing the adjustment of the spacing between each grinding plate 204, so as to adapt to the need of grinding the inner surface of the pipe body 101.

[0028] When adjusting the spacing of each set of grinding plates 204, the spacing between each set of grinding plates 204 from the base plate 102 to the working plate 104 increases sequentially. After the spacing of each set of grinding plates 204 is adjusted, the working plate 104 can be moved closer to the pipe body 101 by starting the push cylinder 103, which in turn moves the processing pipe 202 closer to the pipe body 101. During the process of the processing pipe 202 moving closer to the pipe body 101, the rotation motor 205 is started to drive the processing pipe 202 to rotate.

[0029] As the processing tube 202 moves closer to the pipe body 101, when the processing tube 202 is inserted into the pipe body 101, the rotation of the grinding plate 204 can be used to grind the inner wall of the pipe body 101. Moreover, the multiple sets of grinding plates 204 with different spacings on the side wall of the processing tube 202 will achieve multi-stage grinding of the inner wall of the pipe body 101. This ensures the grinding effect of the inner wall of the pipe body 101 while reducing the cumbersomeness and grinding time of the grinding operation, thereby improving the efficiency of the pretreatment of the inner surface of the pipe.

[0030] Example 2

[0031] Please see Figure 2 and Figure 3 This embodiment further illustrates Example 1. The processing tube 202 shown in the figure is provided with a rotating assembly for rotating each rotating plate 203. The rotating assembly includes a T-shaped rotating rod 401 rotatably connected to one end of the processing tube 202 away from the processing rod 201. A spline plate 402 is fixedly connected to one end of the T-shaped rotating rod 401 located inside the processing tube 202. Each rotating plate 203 has a spline hole 403, and each spline hole 403 is matched with the spline plate 402. The processing tube 202 is provided with a telescopic assembly for extending and retracting the T-shaped rotating rod 401.

[0032] It should be noted here that: by setting the rotating component, when adjusting the spacing of one of the groups of grinding plates 204, the spline plate 402 at one end of the T-shaped rotating rod 401 can be pushed to engage the spline hole 403 on the rotating plate 203 connected to the grinding plate 204 to be adjusted. Then, by rotating the T-shaped rotating rod 401, the rotating plate 203 is driven to rotate, which in turn drives the spiral strip 303 to rotate.

[0033] During the rotation of the spiral strip 303, the spiral transmission between the spiral strip 303 and each connecting plate 302, and the guiding action of each driving plate 301, drive each grinding plate 204 to move closer or further away from each other, thereby realizing the adjustment of the distance between each grinding plate 204, so as to adapt to the need of grinding the inner surface of the pipe body 101.

[0034] It is worth noting that this rotating component is similar to the transmission structure of a three-jaw chuck. In screw drives, the helix angle is a key factor affecting the self-locking performance. When the helix angle is less than the equivalent friction angle of the screw pair, the screw pair will produce a self-locking phenomenon according to mechanical principles.

[0035] Please see Figure 2 and Figure 3 The telescopic assembly shown in the figure includes a spring 501, which is sleeved on the T-shaped rotating rod 401 and located on the outer side wall of the processing tube 202. One end of the spring 501 is connected to the side wall of the T-shaped rotating rod 401, and the other end of the spring 501 is fixedly connected to a rotating ring 502. The rotating ring 502 is rotatably connected to the end of the processing tube 202 away from the processing rod 201.

[0036] It should be noted here that the telescopic component is designed to provide a reset function for the T-shaped rotating rod 401 after use, thereby ensuring that the spline plate 402 at one end of the T-shaped rotating rod 401 is inside the processing tube 202 and does not come into contact with any of the rotating plates 203.

[0037] Example 3

[0038] Please see Figure 1 This embodiment further illustrates other embodiments. The fixing component shown in the figure includes an L-shaped plate 601 that is slidably connected to the bottom plate 102 near the pipe body 101. The L-shaped plate 601 is slidably connected to the bottom plate 102 via a guide rail. A fixing plate 602 is fixedly connected to the side of the support plate 105 near the L-shaped plate 601. An arc-shaped clamping plate 603 is fixedly connected to the opposite ends of the L-shaped plate 601 and the fixing plate 602. A mounting plate 604 is fixedly connected to the side of the bottom plate 102 near the arc-shaped clamping plate 603. The mounting plate 604 is provided with a push rod motor 605 for pushing the L-shaped plate 601.

[0039] It should be noted that by setting up the fixing components, the arc-shaped clamping plate 603 can be used, and under the pushing action of the push rod motor 605, the pipe body 101 can be clamped and fixed, thereby ensuring the positional stability during the grinding process of the inner surface of the pipe body 101.

[0040] In a more optimized version, an arc-shaped baffle can be set on the side of the two arc-shaped clamping plates 603 near the bottom plate 102, and the edge of the arc-shaped baffle does not exceed the inner diameter of the pipe body 101. Thus, the positioning and suspended clamping of the pipe body 101 are achieved by using the blocking effect of the two arc-shaped baffles.

[0041] It is worth noting that the model of the 605 push rod motor is DT-1KN. As it is existing technology, its specific structure and working principle have been mastered by those in the field, and will not be elaborated on here.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
