Description

Technical Field

[0001] This invention relates to the field of RTP pipe production, and particularly to an apparatus and process for strip preparation and winding for continuous production of large-diameter RTP pipes. Background Technology

[0002] RTP pipes typically consist of a multi-layer structure. The winding device is responsible for spirally winding high-strength reinforcing material at a specific angle onto the core or inner lining during continuous production, forming a reinforcing layer that can withstand internal pressure or external loads.

[0003] RTP pipes, with their lightweight, high strength, and corrosion resistance, are widely used in oil and gas transportation, chemical fluid transportation, and other fields. The winding quality of the copper strip in its reinforcing layer directly determines the pipe's mechanical properties, electrical conductivity, and service life. Therefore, ensuring precise winding position and uniform spiral spacing of the copper strip is crucial. However, in actual production, inconsistencies in the thickness and width of the copper strip have become a key factor leading to winding position deviations and reduced product quality.

[0004] From a materials perspective, copper strip is prone to thickness tolerance issues during rolling, annealing, and other processing stages due to factors such as equipment precision, process stability, and raw material characteristics. Differences in thickness and width cause changes in lateral or frictional forces as the copper strip passes through guiding devices (such as guide rollers and tension wheels), leading to deviations from the intended winding trajectory. Under high-speed winding conditions, even minute dimensional deviations are rapidly amplified, resulting in accumulated winding position offsets, uneven helix spacing, and impacting the overall strength distribution of the pipeline.

[0005] Misalignment in the copper strip winding position directly affects the overall performance of the RTP pipe. Uneven winding can lead to stress concentration when the pipe is under load, reducing circumferential tensile strength and burst resistance. When the winding position deviates, the pressure resistance of the RTP pipe decreases, and its service life is shortened.

[0006] To address the aforementioned issues, an apparatus and process for strip preparation and winding in the continuous production of large-diameter RTP pipes are proposed. Summary of the Invention

The width of the first push plate 614 is less than the thickness of the strip material, so that the first push plate 614 will not contact the outer ring surface of the copper strip. A first groove 615 is provided on the side of the pressure plate 613 near the clamp 4. A first slider 616 is provided on the inner side of the first groove 615 and is fixedly connected to the first push plate 614. Elastic rubber pads 617 are fixedly connected to both sides of the first slider 616. The width of the first slider 616 near the clamp 4 is less than the width of the first slider 616 away from the clamp 4, and the width of the first groove 615 near the clamp 4 is less than the width of the first slider 616 away from the clamp 4, so that the first slider 616 will not move out of the inner side of the first groove 615 when it moves inside the first groove 615. The external structure of the pressure plate 613 is arc-shaped, so that the pressure plate 613 can fit against the outer side of the copper strip.

[0027] The reciprocating assembly 71 includes a second push plate 7101 fixedly connected to one end of the air rod 611 and the other side. A first guide groove 7102 is provided on one side of the inner surface of the second push plate 7101. The appearance structure of the first guide groove 7102 is "V". A second guide groove 7103 is provided on the other side of the first guide groove 7102. A third connecting rod 7104 is laterally slidably connected to the outer side of the air rod 611.

The appearance structure of the second guide groove 7103 is a horizontal straight line. The first guide groove 7102 and the second guide groove 7103 are a group. There are multiple groups of the first guide groove 7102 and the second guide groove 7103 equidistantly distributed, so that the first guide rod 7106 can move to both sides when it moves inside the first guide groove 7102. The appearance structure of the third push plate 7105 is a cuboid. The outer side of the third push plate 7105 fits against the inner side of the sleeve 7107, so that the third push plate 7105 will not rotate when the sleeve 7107 moves.

[0028] The centering component 72 includes a second connecting rod 7201 disposed below the third push plate 7105. A third guide groove 7202 is provided on the lower surface of the third push plate 7105. A second sliding groove 7203 is provided on the side of the pressure plate 613 away from the clamp 4. A striking plate 7204 fixedly connected to the second connecting rod 7201 is provided inside the second sliding groove 7203. A second guide rod 7205 fixedly connected to the second connecting rod 7201 is provided inside the third guide groove 7202.

[0029] The process of using the strip preparation and winding device for continuous production of large-diameter RTP tubes involves feeding the strip through the feeding roller 5 and providing epoxy resin adhesive through the adhesive tank 604. The first motor 3 controls the rotation of the RTP tube and the second motor 601 controls the lateral movement of the feeding roller 5. A pre-reserved spiral spacing facilitates the first push plate 614 to push the copper strip. The third motor 606 drives the pressure plate 613 to adjust the spiral spacing of the first push plate 614. The pressure plate 613 vibrates to remove air bubbles.

[0030] When winding is required, the copper strip is placed on the feeding roller 5, and the copper strip is fixed to the RTP tube from the discharge port 605. The second motor 601 is started to drive the first threaded rod 602 to rotate, so that the glue tank 604 and the feeding roller 5 move. At the same time, the first motor 3 is started to drive the clamp 4 to rotate, so that the RTP tube fixed to the outside of the clamp 4 rotates. The feeding device inside the glue tank 604 is started to discharge the epoxy resin from the discharge port of the glue tank 604, so that the copper strip can be wound on the RTP tube.

[0031] Because the spiral spacing of the copper strip is difficult to control effectively, when the copper strip is wound around the outside of the RTP tube, the external controller controls the rotation speed of the first motor 3 and the rotation speed of the second motor 601 to make the spiral spacing slightly larger than normal, thus preventing the copper strip from overlapping. Once the spiral spacing has been created, the third motor 606 is started to drive the second threaded rod 607 to rotate, which in turn drives the third support plate 608, the first cylinder 609, and the second cylinder 610 to move laterally, causing the first push plate 614 to move to the spiral spacing position. The first cylinder 609 is then started to drive the air rod 6... 11, the first connecting rod 612, the first push plate 614, and the pressure plate 613 move toward the copper strip, causing the first push plate 614 to be locked between the spiral gaps, and the pressure plate 613 to be in contact with the outer side of the copper strip. When the first motor 3 drives the clamp 4, the RTP tube, and the copper strip to rotate, the copper strip touches the first push plate 614. Because the inner side of the copper strip is covered with epoxy resin, and because the epoxy resin has low initial viscosity and good fluidity, it can play a lubricating role between the copper strips. The copper strip will move to one side along the trajectory of the first push plate 614, thereby reducing the spiral gap of the copper strip and improving the winding effect of the copper strip.

[0032] When the two sides of the copper strip are in contact and the copper strip does not move, the first push plate 614 will be displaced by the copper strip because the elastic rubber pads 617 are fixedly connected to both sides of the first slider 616. The elastic rubber pads 617 will be compressed, reducing damage to the copper strip and making the copper strip winding effect better.

[0033] Because the pressure plate 613 squeezes the outer side of the copper strip, when the copper strip moves, even if the two sides of the copper strip have already come into contact, the first push plate 614 still has the force to push the copper strip to move, so that the copper strip will not lift up, resulting in a better copper strip winding effect.

[0034] When the pneumatic rod 611 pushes, it causes the second push plate 7101, the first guide groove 7102, and the second guide groove 7103 to move. When the first cylinder 609 and the pneumatic rod 611 move laterally driven by the third support plate 608, the third connecting rod 7104, the third push plate 7105, and the first guide rod 7106 move. Because the first guide rod 7106 is inside the first guide groove 7102, and because the first guide groove 7102 has a "V"-shaped external structure, the first guide rod 7106 and the third push plate 7105 will... The reciprocating motion drives the third guide groove 7202 to reciprocate, which in turn causes the second guide rod 7205, the second guide rod 7205 and the striking plate 7204 to reciprocate. This causes the striking plate 7204 to strike the pressure plate 613, transmitting the force through the pressure plate 613 to the epoxy resin adhesive on the inner side of the copper strip. At this time, the first guide rod 7106 has moved to the inner side of the second guide groove 7103. The first guide rod 7106 remains stationary, and the striking plate 7204 also remains stationary, reducing the vibration of the pressure plate 613 rebounding. Because the initial spiral pitch is slightly larger than normal, and the width of the first push plate 614 is less than the thickness of the strip material, the first push plate 614 will not block the two sides of the copper strip. This allows the epoxy resin on the inner side of the copper strip to move to both sides as much as possible, so that air bubbles can be better discharged and the epoxy resin can be distributed more evenly, thereby making the copper strip fixation effect better.

[0035] When the striking plate 7204 strikes the pressure plate 613, the already laid copper strip will rotate, thereby impacting and vibrating all the laid copper strips, increasing the air bubble discharge rate, allowing the epoxy resin to be distributed more evenly, and resulting in better copper strip fixing effect.

[0036] After the first layer of copper strip is laid, the first cylinder 609 is started to drive the corresponding first push plate 614 and pressure plate 613 to move back. The second cylinder 610 is started to drive the corresponding first push plate 614 and pressure plate 613 to repeat the above movement, so as to complete continuous production and improve work efficiency.

[0037] Because the first push plate 614 pushes the copper strip while the striking plate 7204 strikes the pressure plate 613, a compound motion is generated, which allows the air bubbles to be discharged better and the epoxy resin liquid to be distributed more evenly.

Start the second motor (601) to drive the first threaded rod (602) to rotate, so that the glue tank (604) and the feeding roller (5) move. At the same time, start the first motor (3) to drive the clamp (4) to rotate, so that the RTP pipe fixed on the outside of the clamp (4) rotates. Start the feeding device inside the glue tank (604) to discharge the epoxy resin from the discharge port of the glue tank (604), so that the copper strip can be wound onto the RTP pipe.
