Description

Technical Field

[0001] The invention relates to the technical field of glass fiber winding, in particular to a glass fiber winding device and a patching method for oil and gas pipelines. Background Art

[0002] During oil and gas pipeline construction, physical damage to the anti-corrosion coating is a common occurrence during handling, long-distance transportation, pipe laying, trenching, and backfilling. Poor mechanical properties of the outer anti-corrosion coating not only increase the amount of on-site repair work, increasing construction costs and impacting pipeline construction progress, but also pose a risk to the long-term safe operation of the pipeline. Therefore, ensuring the mechanical properties of the outer anti-corrosion coating is particularly important. Currently, oil and gas pipelines in China are more commonly coated with a three-layer polyethylene anti-corrosion coating. During long-term use, the three-layer polyethylene anti-corrosion layer pipe may be damaged due to changes in the pH value of the soil in the environment, fluctuations in the groundwater level, and the activity of microorganisms. Once the anti-corrosion layer is damaged, the metal layer of the pipe will be directly exposed to the outside world, causing electrochemical corrosion of the metal layer of the pipe, posing a serious threat to the strength and sealing of the pipe, thereby causing oil and gas leakage. Therefore, when the anti-corrosion layer is damaged, it needs to be patched in time. Our company has designed and adopted a double patching solution of solvent-free epoxy coating + glass fiber composite material layer. In this solution, the glass fiber composite material used for patching needs to be wrapped around the location where the anti-corrosion layer is damaged on the oil and gas pipeline.

[0003] Chinese patent CN116373273B discloses an automated filament winding device for repairing defective pipes.

[0004] The above-mentioned equipment can be used to repair oil and gas pipelines. However, since the diameter of domestic oil and gas pipelines is usually between 200 mm and 720 mm, and the laying of oil and gas pipelines will inevitably pass through rural areas and forests, there will be traffic difficulties in some rural and forest areas. When the diameter of the oil and gas pipeline is large, the volume of the winding equipment for repairing the oil and gas pipeline will also increase accordingly. When using the above-mentioned equipment to repair large-diameter oil and gas pipelines, there is a problem of difficulty in handling and carrying due to the large volume of the equipment. Therefore, when it is necessary to patch the oil and gas pipeline in an area with inconvenient transportation, it is difficult to move the equipment to the patching position.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] Example 1

[0053] See also Figure 1 and Figure 11 The present invention provides a glass fiber winding device, comprising an annular support 1, a support wheel assembly 2, a translation assembly 3, and a winding component. The annular support 1 is sleeved on the oil and gas pipeline to be patched, the support wheel assembly 2 is rotatably mounted on the annular support 1, and the support wheel assembly 2 is in rolling contact with the wall of the oil and gas pipeline. The translation assembly 3 is used to move the annular support 1 along the length direction of the pipeline.

[0054] The annular bracket 1 includes a fixed plate 11 and a movable plate 12, and the movable plate 12 is rotatably mounted on both ends of the fixed plate 11;

[0055] The translation assembly 3 includes a hoop 31, a belt 33, and a moving mechanism 32. The hoop 31 is provided on both sides of the annular support 1 and is strapped to the oil and gas pipeline to be patched. Both ends of the belt 33 are connected to the hoop 31. The moving mechanism 32 is installed on the annular support 1 and is used to drive the annular support 1 to move along the length direction of the belt 33.

[0056] The winding component includes a winding component 4 and a winding component 5. The winding component 4 is detachably mounted on the annular bracket 1 and rotates around the annular bracket 1. The winding component 5 is mounted on the winding component 4 and rotates and unwinds while moving with the winding component 4.

[0057] As can be seen from the above, the glass fiber winding device, by setting up an annular bracket 1, can conveniently install the annular bracket 1 on the oil and gas pipeline because the fixed plate 11 and the movable plate 12 constituting the annular bracket 1 can rotate. At the same time, due to the setting of the hoop 31, the belt 33 and the moving mechanism 32, the translation component 3 that controls the radial movement of the annular bracket 1 along the oil and gas pipeline is convenient for disassembly and storage. In addition, since the surrounding component 4 can also be easily removed from the annular bracket 1, the glass fiber winding device as a whole can be divided into three parts for storage and storage respectively, and can be quickly assembled when in use, making the glass fiber winding device easy to carry and use.

[0058] When using the device, the two hoops 31 are fixed to the two sides of the position to be patched on the oil and gas pipeline, and the movable plate 12 is rotated so that the fixed plate 11 is directly inserted into the oil and gas pipeline between the two hoops 31. Then the movable plate 12 is reversed so that the annular bracket 1 is re-formed into a complete ring.

[0059] Connect the belt 33 to the moving mechanism 32 mounted on the ring bracket 1, and connect the two ends of the belt 33 to the hoop 31, while ensuring that the belt 33 is straight;

[0060] Install the wrapping assembly 4 onto the annular support 1, and install the glass fiber composite material to be wound onto the oil and gas pipeline onto the winding assembly 5, so that a portion of the glass fiber composite material is wound onto the oil and gas pipeline;

[0061] The moving mechanism 32 and the winding assembly 4 are controlled to work so that the winding assembly 5 rotates and unwinds while the winding assembly 4 moves.

[0062] Example 2

[0063] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 9As shown, the difference between this embodiment and the above embodiment is that the annular bracket 1 also includes a transverse axis 13 and a vertical axis 14, the transverse axis 13 and the vertical axis 14 are fixedly connected, the transverse axis 13 is rotatably connected to the fixed plate 11, and the vertical axis 14 is rotatably connected to the movable plate 12, a limiting spring 15 is fixedly installed on one of the movable plates 12, a limiting rod 16 is fixedly installed on the limiting spring 15, and a limiting hole 17 is provided on each of the movable plates 12, and the limiting rod 16 is adapted to be plugged into the limiting hole 17.

[0064] As can be seen from the above, by setting the transverse axis 13 and the vertical axis 14, the annular bracket 1 can be folded up when stored, which fully reduces the space required for storing the annular bracket 1; by setting the limit spring 15, the limit rod 16 and the limit hole 17, when the movable plates 12 are close to each other so that the annular bracket 1 forms a complete ring, the limit rod 16 is inserted into the two limit holes 17, which can limit the rotation direction of the movable plate 12, so that when the annular bracket 1 is sleeved on the oil and gas pipeline, the support wheel assembly 2 installed on the movable plate 12 will not be separated from the oil and gas pipeline due to the rotation of the movable plate 12, and, in this embodiment, when the movable plates 12 are fixed to each other, due to the rolling contact between the support wheel assembly 2 and the pipe wall of the oil and gas pipeline, under the support of the support wheel assembly 2 on the fixed plate 11 and the movable plate 12 respectively, the movable plate 12 cannot and cannot rotate in the direction of the transverse axis 13.

[0065] The support wheel assembly 2 includes a swivel seat 21, a sleeve 22, a slide rod 23, a connecting plate 24 and a roller 25. The swivel seat 21 is fixedly installed on the outer wall of the annular bracket 1, the sleeve 22 is rotatably connected to the swivel seat 21, the slide rod 23 is slidably connected to the sleeve 22, and a support spring 26 is provided inside the sleeve 22. The two ends of the support spring 26 are respectively fixedly connected to the sleeve 22 and the slide rod 23, the connecting plate 24 is fixedly connected to the slide rod 23, and the roller 25 is rotatably installed on the connecting plate 24.

[0066] As can be seen from the above, by setting the swivel seat 21 and the sleeve 22, the support wheel assembly 2 can rotate between the inner and outer sides of the annular bracket 1. When the annular bracket 1 is folded, the support wheel assembly 2 is rotated to the outside of the annular bracket 1, which can avoid the support wheel assemblies 2 from colliding with each other and hindering the rotational contact between the fixed plate 11 and the movable plate 12. By setting the sleeve 22, the slide rod 23 and the support spring 26, when the roller 25 rolls on the surface of the oil and gas pipeline, large particles sticking to the surface of the oil and gas pipeline will not prevent the roller 25 from passing.

[0067] The swivel seat 21 includes a mounting plate 211 and a rotating rod 212. The mounting plate 211 is fixedly mounted on the outer wall of the annular bracket 1. The rotating rod 212 is fixedly connected to the sleeve 22, and the rotating rod 212 is rotatably connected to the mounting plate 211. A connecting plate 213 is fixedly mounted on one end of the rotating rod 212, and an insertion rod 214 is inserted into the connecting plate 213. A socket 215 adapted to the insertion rod 214 is provided on the swivel seat 21, and a return spring 216 is fixedly mounted between the swivel seat 21 and the insertion rod 214.

[0068] As can be seen from the above, when the rotating rod 212 rotates, the connecting piece 213 rotates with the insertion rod 214. Through the arrangement of the insertion rod 214, the socket 215 and the return spring 216, when the insertion rod 214 is inserted into the socket 215, the rotating rod 212 cannot rotate. In this embodiment, there are two sockets 215 opened on the rotating seat 21. When the insertion rod 214 is inserted into different sockets 215, the sleeve 22 can be fixed at different inclination angles.

[0069] Example 3

[0070] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 11 and Figure 12 As shown, the difference between this embodiment and the above embodiment is that the hoop 31 includes a hard plate 311 and a tie 312, the hard plate 311 is a semi-annular plate, and the inner diameter of the hard plate 311 is the same as the outer diameter of the oil and gas pipeline to be repaired, one end of the tie 312 is fixedly connected to one end of the hard plate 311, and the other end of the tie 312 is detachably connected to the other end of the hard plate 311, the inner side wall of the hard plate 311 is also provided with an anti-slip strip 313, the translation assembly 3 also includes an extension rod 34, a collar 314 is fixedly mounted on the hard plate 311, the extension rod 34 is slidably connected to the collar 314, the side of the collar 314 is slidably plugged with an insert 35, the insert 35 is adapted to be plugged into the extension rod 34, and an anti-slip spring 36 is fixedly mounted between the insert 35 and the collar 314.

[0071] As can be seen from the above, in this embodiment, the detachable connection between the strap 312 and the hard plate 311 can use bolts or various other fixing structures. Since the fixing method of the strap 312 is widely available in the prior art, it is not described in detail in this embodiment; by providing an extension rod 34, the height of the belt 33 can be increased so that the belt 33 does not interfere with the movement of the surrounding component 4. By providing a ring 314, the main part of the extension rod 34 can be moved to the inner side of the hard plate 311 when it is stored.

[0072] The moving mechanism 32 includes a translation drive gear 321, a mounting frame 322 and a translation drive motor 323. The mounting frame 322 is fixedly mounted on the fixed plate 11. The translation drive gear 321 is rotatably mounted inside the mounting frame 322. The two side surfaces of the belt 33 are respectively engaged with the translation drive gear 321. The translation drive motor 323 is fixedly mounted on the mounting frame 322, and the driving end of the translation drive motor 323 is fixedly connected to one of the translation drive gears 321.

[0073] As can be seen from the above, when the translation drive motor 323 is started, the translation drive gear 321 is engaged with the belt 33 , so that the translation drive gear 321 can pull the annular bracket 1 to move along the length direction of the belt 33 .

[0074] Example 4

[0075] like Figure 7 、 Figure 10 、 Figure 11 and Figure 13 As shown, the difference between this embodiment and the above embodiment is that the surrounding component 4 includes a main plate 41, a sub-plate 42, a rotating shaft 43, an inner support wheel 44 and an outer clamping wheel 45, the inner support wheel 44 and the outer clamping wheel 45 are in contact with the inner wall and outer wall of the annular bracket 1 respectively, the main plate 41, the sub-plate 42 and the inner support wheel 44 are all rotatably connected to the rotating shaft 43, and the outer clamping wheel 45 is rotatably installed on the main plate 41 and the sub-plate 42 at one end away from the rotating shaft 43.

[0076] As can be seen from the above, by setting up the surrounding component 4 including the main plate 41, the sub-plate 42, the rotating shaft 43, the inner support wheel 44 and the outer clamping wheel 45, when the angle between the main plate 41 and the sub-plate 42 is changed, the inner support wheel 44 and the outer clamping wheel 45 can respectively clamp the inner and outer side walls of the annular bracket 1, so that the surrounding component 4 can run stably on the annular bracket 1.

[0077] The surround assembly 4 also includes a clamping assembly 46, which includes a rotating mounting sleeve 461, a threaded mounting sleeve 462 and a threaded rod 463. The rotating mounting sleeve 461 and the threaded mounting sleeve 462 are respectively rotatably mounted on the main board 41 and the sub-board 42, the threaded rod 463 is rotatably connected to the rotating mounting sleeve 461, and the threaded rod 463 is threadedly connected to the threaded mounting sleeve 462.

[0078] As can be seen from the above, by setting the rotating mounting sleeve 461, the threaded mounting sleeve 462 and the threaded rod 463, when the threaded rod 463 is rotated, the distance between the rotating mounting sleeve 461 and the threaded mounting sleeve 462 can be changed, thereby changing the angle between the main board 41 and the sub-board 42.

[0079] The surround assembly 4 further includes a drive assembly 47, which includes a surround drive gear 471 and a surround drive motor 472. The surround drive gear 471 is fixedly mounted on the rotating shaft 43, and the surround drive motor 472 is fixedly mounted on the main board 41, and the drive end of the surround drive motor 472 is fixedly connected to the rotating shaft 43.

[0080] The inner wall of the annular bracket 1 is provided with a tooth pattern 18 , which is adapted to mesh with the surrounding driving gear 471 . The outer wall of the annular bracket 1 is provided with an annular groove 19 , which is slidably adapted to the outer clamping wheel 45 .

[0081] As can be seen from the above, when the surround drive motor 472 drives the surround drive gear 471 to rotate through the rotating shaft 43, the surround drive gear 471 is engaged with the tooth pattern 18, so that the surround component 4 can rotate around the annular bracket 1. At the same time, since the annular groove 19 provided on the outer wall of the annular bracket 1 is slidably adapted to the outer clamping wheel 45, the surround component 4 can be prevented from falling off the annular bracket 1 when it surrounds the annular bracket 1.

[0082] The winding assembly 5 includes a reel 51, a driven shaft 52 and a driven gear 53. The driven shaft 52 is rotationally connected to the main board 41 and fixedly connected to the reel 51. The driven gear 53 is fixedly mounted on the driven shaft 52 and meshed with the surrounding drive gear 471.

[0083] As can be seen from the above, by providing the driven shaft 52 and the driven gear 53 , the unwinding roller 51 can rotate along with the rotation of the rotating shaft 43 .

[0084] Example 5

[0085] See also Figure 1 - Figure 13 The present invention also discloses a method for patching an oil and gas pipeline, the specific steps of which are:

[0086] Fix the two hoop rings 31 to the two sides of the oil and gas pipeline where the joint is to be patched, and rotate the movable plate 12 so that the fixed plate 11 is directly inserted into the oil and gas pipeline between the two hoop rings 31. Then reverse the movable plate 12 so that the annular bracket 1 is re-formed into a complete ring.

[0087] Connect the belt 33 to the moving mechanism 32 mounted on the ring bracket 1, and connect the two ends of the belt 33 to the hoop 31, while ensuring that the belt 33 is straight;
