Description

Technical Field

[0001] This invention relates to the field of composite pipe manufacturing technology, specifically to a high-strength composite pipe and its manufacturing method. Background Technology

[0002] Steel-reinforced plastic composite pipe is a new type of double-sided anti-corrosion pressure pipe made of metal and plastic. It usually uses a high-strength plastic-coated steel wire mesh skeleton as the core reinforcement, with steel wires spirally wound in both directions to form a mesh skeleton. Some also use a mesh structure with holes punched from steel plates as the skeleton. High-density polyethylene (HDPE) is used as the matrix, wrapped inside and outside the steel skeleton, and a high-performance adhesive resin layer is used to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene to form a whole. In addition, the production process of high-strength composite pipe requires the use of corresponding steel skeleton welding equipment. However, the metal skeleton inside composite pipes is often reinforced by welding steel wires arranged axially and spirally wound in both directions. This makes it impossible for the composite pipe to undergo effective elastic deformation to buffer the extrusion force when subjected to lateral extrusion during use. As a result, the composite pipe will undergo irreversible deformation after being subjected to continuous periodic micro-extrusion, which reduces the overall structural strength and service life of the composite pipe. Meanwhile, when the steel frame is wound using the steel frame welding equipment, it is not possible to quickly wrap the steel mesh belt to the outside of the steel frame as needed, nor is it possible to quickly adjust the arrangement of the steel mesh belt, thus reducing the convenience of steel frame production. Summary of the Invention

[0003] This invention provides a high-strength composite pipe and its manufacturing method, which effectively solves the problems mentioned in the background art. The internal metal skeleton of composite pipes is often reinforced by welding steel wires arranged axially and spirally wound in both directions. This prevents the composite pipe from undergoing effective elastic deformation to buffer the lateral compressive force during use, leading to irreversible deformation after continuous periodic micro-compression. Consequently, the overall structural strength and service life of the composite pipe are reduced. Furthermore, when winding the steel skeleton using steel skeleton welding equipment, it is impossible to quickly wind the steel mesh belt onto the outside of the steel skeleton as needed, and the arrangement of the steel mesh belt cannot be quickly adjusted, thus reducing the convenience of steel skeleton production.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for manufacturing a high-strength composite pipe, comprising the following steps: S1. Inner ring welding: The inner ring reinforcing warp is arranged and guided by the front winding welding seat, and the inner ring spiral weft is welded to the outside of the inner ring reinforcing warp by electric spark to complete the initial forming of the inner ring structure of the composite tube. The structure after the initial forming is guided by the central guide horizontal axis. S2. Mesh belt winding: The middle layer steel wire mesh belt is wrapped around the outer side of the inner spiral weft line through the middle layer mesh belt winding welding seat, and the middle layer steel wire mesh belt is welded to the outer side of the inner spiral weft line through electric spark welding to complete the welding and forming of the middle layer of the steel skeleton. S3. Outer ring welding: The outer ring reinforcing warp and outer ring spiral weft are sequentially arranged and welded to the outside of the middle layer steel wire mesh through the subsequent cladding welding structure to complete the combined processing and forming of the composite pipe steel skeleton; S4. Extrusion Cooling: The formed steel skeleton is pulled by an external traction device and passed through the inside of the extrusion head of the extrusion equipment, so that the molten composite material is wrapped around the outside of the steel skeleton through the extrusion equipment, and the newly formed composite pipe is passed through the inside of the spray cooling equipment to achieve cooling and forming of the composite pipe. S5. Cutting and Marking: The relevant information of the composite pipe is printed on the outside of the composite pipe using a laser marking device. Then, the composite pipe is cut into appropriate lengths using a cutting device, and the processed pipes are transported and stored using a lifting device.

[0005] Preferably, in a high-strength composite pipe, an inner spiral weft is spirally wound and welded around the outer side of the inner reinforcing warp, and a middle layer of steel wire mesh is wrapped and welded around the outer side of the inner spiral weft.

[0006] Preferably, the outer ring of reinforcing warp wires is welded at equal intervals along the circumferential direction on the outer side of the middle layer steel wire mesh belt; The outer reinforcing warp and the inner spiral weft are welded together by electrical discharge welding.

[0007] Preferably, the outer ring reinforcing warp is spirally wound and welded with an outer ring spiral weft; The outer spiral weft is adjusted according to the spiral direction of the inner spiral weft and the middle layer of steel wire mesh.

[0008] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. The inner layer of the composite pipe is formed by reinforcing warp and spiral weft threads, creating a stable support structure. The spiral arrangement of the inner spiral weft threads enhances the pipe's bending resistance, preventing stress concentration and localized deformation, thus ensuring structural integrity and long-term reliability under complex working conditions. The outer layer of reinforcing warp and spiral weft threads forms a strengthening structure, improving the overall structural strength and resistance to external pressure. A middle layer of steel wire mesh reinforces the area between the inner spiral weft and outer reinforcing warp threads. The deformable mesh structure allows the composite pipe to undergo slight elastic deformation under continuous periodic external pressure, effectively improving its overall structural strength, compressive strength, and service life.

[0009] 2. A central dynamic splicing winding and laying mechanism is set up. Through the cooperation of the various components inside the central dynamic splicing winding and laying mechanism, the production adjustment process of composite pipe is optimized. Through the splicing structure design of the outer side of the mesh belt receiving roller at the top of the support guide slide, the outer side of the mesh belt receiving roller is protected. At the same time, the ring structure formed by the arc splicing protective rail provides auxiliary support for the splicing rotating disk as a whole. In addition, through the self-support balance of each splicing component, the stress condition of the splicing rotating disk as a whole is improved, the stability of the production equipment operation is improved, and the convenience of replacing and adjusting the mesh belt receiving roller is effectively improved, further improving the ease of use and safety of the production equipment. By dynamically adjusting the components on the top of the base plate from the side, and by transferring the kinetic energy of the support guide slide through the front transmission cable and the rear adjustment cable, the axial force of the support guide slide during contraction is transferred through the dynamic sliding and swinging of the dynamic swing plate and its bottom components. This prevents the support guide slide from accelerating the aging and damage of the limiting and driving components inside the equipment during periodic movement. At the same time, the double-movement sliding structure design of the counterweight front pressure block and the adjusting counterweight block, together with the dynamic swing plate, forms a dynamic lever structure, which further improves the stability of each component during the operation of the production equipment and effectively increases the service life of the production equipment. By using a limiting guide rod and a support guide rail in conjunction with a telescopic drive tube, the position of the support guide slide can be actively adjusted. This allows the splicing rotating disc to either spirally wind the middle layer steel wire mesh onto the composite pipe steel frame via the central drive splicing pipe during use, or to separate the splicing rotating disc from the central drive splicing pipe via the sliding of the support guide slide. The middle layer steel wire mesh can then be laid axially onto the outside of the composite pipe frame via a circumferentially fixed mesh belt receiving roller. This effectively expands the functionality of the production equipment, enabling it to spirally wind the middle layer steel wire mesh onto the outside of the composite pipe frame or lay it axially onto the outside of the steel frame, further improving the safety and convenience of using the middle layer steel wire mesh.

[0010] 3. A differential sliding synchronous adjustment guide mechanism is set up. Through the cooperation between the various components inside the differential sliding synchronous adjustment guide mechanism, the guiding and disassembly process of the production equipment is optimized. Through the cooperation between the tail end limit seat and the limit pin, the arc splicing protective rail and the circular rotating frame can be quickly locked and limited. Through the cooperation between the various components inside the circular rotating frame and the relative movement between the circular rotating frame and the splicing rotating plate, multiple sets of middle section rotating swing frames and tail end rotating swing frames can be quickly and synchronously adjusted, thereby effectively improving the convenience of production equipment adjustment. At the same time, by connecting the various components at the end of the adjustment seat, the middle layer steel wire mesh belt can be guided at multiple angles, further improving the stability of the middle layer steel wire mesh belt winding and laying, thereby indirectly improving the ease of use of the production equipment and the overall quality of the composite pipe steel skeleton. Meanwhile, through the cooperation of the components at the top of the sliding arc support, and by using the buffer telescopic spring to buffer the sides of the sliding arc support, the sliding stability of the components connected on the circular rotating frame is effectively improved, making the adjustment process of the production equipment more stable. In summary, through the cooperation between the various components of the central dynamic splicing winding and laying mechanism and the differential sliding synchronous adjustment and guiding mechanism, and through the splicing structure and dynamic buffer structure of the bottom sliding guide seat and the top of the side dynamic adjustment base plate, the production equipment can be quickly adjusted as needed during use. This ensures that the production equipment can be quickly adjusted according to actual production requirements. At the same time, the swing of the dynamic swing plate can transfer and buffer the transmission during the operation of the production equipment, thereby effectively improving the stability of the production equipment and extending its service life.

Detailed Implementation

[0013] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0014] Example 1: As Figure 1 As shown, the present invention provides a technical solution, a method for manufacturing a high-strength composite pipe, comprising the following steps: S1. Inner ring welding: The inner ring reinforcing warp 101 is arranged and guided by the front winding welding seat 2, and the inner ring spiral weft 102 is welded to the outside of the inner ring reinforcing warp 101 by electric spark to complete the initial forming of the inner ring structure of the composite tube, and the structure after the initial forming is guided by the central guide horizontal axis 3. S2. Mesh belt winding: The middle layer steel wire mesh belt 103 is wrapped around the outer side of the inner spiral weft 102 by the middle layer mesh belt winding welding seat 4, and the middle layer steel wire mesh belt 103 is welded to the outer side of the inner spiral weft 102 by electric spark to complete the welding and forming of the middle layer of the steel frame. S3, Outer ring welding: The outer ring reinforcing warp 104 and outer ring spiral weft 105 are sequentially arranged and welded to the outside of the middle layer steel wire mesh 103 through the subsequent cladding welding structure to complete the combined processing and forming of the composite pipe steel skeleton; S4. Extrusion Cooling: The formed steel skeleton is pulled by an external traction device and passed through the inside of the extrusion head of the extrusion equipment, so that the molten composite material is wrapped around the outside of the steel skeleton through the extrusion equipment, and the newly formed composite pipe is passed through the inside of the spray cooling equipment to achieve cooling and forming of the composite pipe. S5. Cutting and Marking: The relevant information of the composite pipe is printed on the outside of the composite pipe using a laser marking device. Then, the composite pipe is cut into appropriate lengths using a cutting device, and the processed pipes are transported and stored using a lifting device.

[0015] like Figure 2-4 As shown, a high-strength composite pipe has an inner spiral weft 102 spirally wound and welded on the outer side of the inner reinforcing warp 101, and a middle layer steel wire mesh 103 wrapped and welded on the outer side of the inner spiral weft 102. The outer ring reinforcing warp lines 104 are welded at equal intervals along the circumferential direction on the outer side of the middle layer steel wire mesh belt 103; The outer reinforcing warp 104 and the inner spiral weft 102 are welded together by electric spark welding at their contact points. The outer ring is reinforced with warp yarn 104, and the outer ring is spirally coiled and welded with outer spiral weft yarn 105. The outer spiral weft 105 is adjusted according to the spiral direction of the inner spiral weft 102 and the middle layer steel wire mesh 103. The inner reinforcing warp 101 and inner spiral weft 102 form the inner skeleton of the composite pipe, providing a stable support structure inside. Simultaneously, the spiral arrangement of the inner spiral weft 102 enhances the bending resistance of the composite pipe, preventing stress concentration and localized deformation, thus ensuring the structural integrity and long-term reliability of the composite pipe under complex working conditions. The outer reinforcing warp 105... 04 and the outer spiral weft 105 form a reinforcing structure in the outer layer of the composite pipe to improve the overall structural strength of the composite pipe and enhance its resistance to external pressure. The middle layer steel wire mesh 103 reinforces the inner spiral weft 102 and the outer reinforcing warp 104. Utilizing the deformable mesh characteristics of the middle layer steel wire mesh 103, the composite pipe can undergo slight elastic deformation after being subjected to continuous periodic external pressure, thereby effectively improving the overall structural strength and compressive strength of the composite pipe and extending its service life. Furthermore, one or more middle-layer steel wire mesh belts 103 can be set, and multiple middle-layer steel wire mesh belts 103 can be spirally wound in the same or opposite directions as required.

[0016] like Figure 5-15 As shown, a central guide horizontal axis 3 is provided in the middle of one side of the front winding welding seat 2, and a middle layer mesh belt winding welding seat 4 is provided outside the central guide horizontal axis 3 at a position corresponding to one side of the front winding welding seat 2.

A splicing rotating disk 502 is slidably engaged on the outer side of the central drive splicing pipe 501 through a spline groove. Splicing mounting seats 503 are evenly and equidistantly arranged on the outer side of the splicing rotating disk 502 along the circumferential direction.

An arc-shaped splicing protective rail 507 is fixedly installed in the middle of the outer side of the mounting protective frame 505 by bolts. The splicing mounting base 503 and the mounting protective frame 505 are connected by bolts. The arc-shaped splicing protective rails 507 are spliced ​​together end to end, and the sides of multiple arc-shaped splicing protective rails 507 are flush with each other. A bottom sliding guide seat 523 is provided on one side of the middle layer mesh belt winding welding seat 4 at the bottom position of the arc-shaped splicing protective rail 507. Limiting guide round rods 524 are fixedly installed on both sides of the top of the bottom sliding guide seat 523. Supporting guide rails 525 are symmetrically installed in the middle of the top surface of the bottom sliding guide seat 523. A support guide slide 508 is slidably installed at the bottom position of the bottom sliding guide 523 corresponding to the bottom position of the arc splicing protective rail 507. A load-bearing arc guide slide 509 is fixedly connected at the middle of the top of the support guide slide 508 corresponding to the outer position of the arc splicing protective rail 507. Telescopic drive tubes 510 are fixedly connected at the two bottom corners on one side of the bottom sliding guide 523. A front transmission cable 511 is fixedly connected to the middle of the bottom end on one side of the support guide slide 508, and a tail adjustment cable 512 is fixedly connected to the middle of the bottom end on the other side of the support guide slide 508. A side dynamic adjustment base plate 513 is fixedly connected to one side of the bottom sliding guide seat 523. Arc-shaped support side rods 514 are fixedly connected to the middle of both sides of the top surface of the side dynamic adjustment base plate 513. A dynamic swing plate 515 is rotatably connected to the top of the inner side of the arc-shaped support side rods 514 through a rotating shaft. The dynamic swing plate 515 has guide bidirectional slide grooves 516 on both sides of the bottom center. A counterweight front pressure block 517 is slidably engaged at one end of the guide bidirectional slide groove 516. A transmission traction spring 518 is symmetrically fixedly connected to the middle of one end of the counterweight front pressure block 517. An adjusting counterweight block 519 is fixedly connected at the bottom of the other end of the transmission traction spring 518 corresponding to the bottom of the guide bidirectional slide groove 516. The weight of the counterweight front pressure block 517 is greater than the weight of the adjusting counterweight block 519. The bottom surface of the support guide slide 508 is tightly slidably fitted with the outer side of the support guide rail 525. The limiting guide round rod 524 slides through both sides of the bottom of the support guide slide 508. The telescopic drive tube 510 passes through the bottom of the middle layer mesh belt winding welding seat 4, and the telescopic drive tube 510 is fixedly connected to the middle layer mesh belt winding welding seat 4. The top of the adjusting counterweight 519 is tightly slidably fitted with the inner wall of the guide bidirectional slide groove 516, the end of the front transmission cable 511 is fixedly connected to the end of the dynamic swing plate 515, and the end of the tail adjusting cable 512 is fixedly connected to the middle of the end of the adjusting counterweight 519. A front guide wheel frame 520 is provided at one end of the side dynamic adjustment base plate 513 corresponding to the outer position of the front transmission cable 511, and a tail guide wheel frame 521 is provided at the other end of the side dynamic adjustment base plate 513 corresponding to the outer position of the tail adjustment cable 512. A horizontal sensor 522 is fixedly installed at the center of the top surface of the dynamic swing plate 515. Through the cooperation of the internal components of the dynamic splicing winding and laying mechanism 5, the production adjustment process of the composite pipe is optimized. Through the splicing structure design of the outer side of the mesh belt receiving roller 506 at the top of the support guide slide 508, the outer side of the mesh belt receiving roller 506 is protected. At the same time, the ring structure formed by the arc splicing protective rail 507 provides auxiliary support for the splicing rotating disk 502. In addition, through the self-support balance of each splicing component, the overall stress of the splicing rotating disk 502 is improved, the stability of the production equipment operation is improved, and the convenience of replacing and adjusting the mesh belt receiving roller 506 is effectively improved, further improving the ease of use and safety of the production equipment. Then, by dynamically adjusting the dynamic coordination of the components at the top of the side dynamic adjustment base plate 513, and by changing the direction of the kinetic energy received by the support guide slide 508 through the front transmission cable 511 and the tail adjustment cable 512, the axial force of the support guide slide 508 is transferred through the dynamic sliding and swinging of the dynamic swing plate 515 and its bottom components. This prevents the support guide slide 508 from accelerating the aging and damage of the limiting components and drive components inside the equipment during periodic oscillation. At the same time, the double-movement sliding structure design of the counterweight front pressure block 517 and the adjusting counterweight block 519, together with the dynamic swing plate 515, forms a dynamic lever structure, which further improves the stability of each component during the operation of the production equipment and effectively improves the service life of the production equipment. The position of the support guide slide 508 can be actively adjusted by the limiting guide rod 524 and the support guide rail 525 in conjunction with the telescopic drive tube 510. This allows the splicing rotating disk 502 to either rotate circumferentially through the central drive splicing tube 501 to spirally wind the middle layer steel wire mesh belt 103 onto the composite pipe steel frame, or to separate the splicing rotating disk 502 from the central drive splicing tube 501 by sliding the support guide slide 508. The middle layer steel wire mesh belt 103 can then be laid axially onto the outside of the composite pipe frame by the circumferentially fixed mesh belt receiving roller 506. This effectively expands the function of the production equipment, allowing it to spirally wind the middle layer steel wire mesh belt 103 onto the outside of the composite pipe frame or lay it axially onto the outside of the steel frame, further improving the safety and convenience of using the middle layer steel wire mesh belt 103. The bottom sliding guide seat 523 is provided with a differential sliding synchronous adjustment guide mechanism 6 at the top.

A connecting adjustment seat 603 is bolted to one side of the splicing rotating disk 502, corresponding to the side of the splicing base plate 504. A front limiting guide roller 604 is installed at the end of the connecting adjustment seat 603 via a connecting plate. A swing adjustment roller 605 is installed on the side of the front limiting guide roller 604 via a swing plate. A middle section rotating swing frame 606 is installed on one side of the swing adjustment roller 605 via a connecting plate and a rotating shaft. A tail end rotating swing frame 607 is rotatably installed at the end of the middle section rotating swing frame 606 via a rotating shaft. Corresponding limiting through holes are opened on the sides of the arc-shaped spliced ​​protective rail 507 and the circular rotating frame 611 at the end positions of the limiting pins 602, and the limiting through holes and the limiting pins 602 are correspondingly engaged. The middle section rotating swing frame 606 and the tail end rotating swing frame 607 are limited by the damping between the rotating shafts. A connecting frame 608 is fixedly connected to the side of the middle section rotating swing frame 606 via a connecting rod. A rubber adjusting connecting tube 609 is fixedly connected to the middle of one side of the top of the connecting frame 608. An end connecting seat 610 is rotatably connected to the end of the rubber adjusting connecting tube 609 via a rotating shaft.

A sliding arc support seat 612 is fixedly connected to the bottom outer side of the circular rotating frame 611. Limiting sliding sleeves 613 are fixedly connected to the bottom sides of the sliding arc support seat 612 at positions corresponding to the outer sides of the limiting guide rods 524. A buffer telescopic spring 614 is fixedly connected to one side of the limiting sliding sleeve 613. The inner wall of the limiting sliding sleeve 613 and the outer side of the limiting guide rods 524 are in close sliding contact. The end of the buffer telescopic spring 614 is fixedly connected to the end face of the bottom sliding guide seat 523. By adjusting the coordination between the components inside the differential sliding synchronous adjustment guide mechanism 6, the guiding and disassembly process of the production equipment is optimized. The cooperation between 601 and the limiting pin 602 allows for quick locking and limiting of the arc-shaped splicing protective rail 507 and the circular rotating frame 611. Through the cooperation between the internal components of the circular rotating frame 611 and the relative movement between the circular rotating frame 611 and the splicing rotating disk 502, multiple sets of middle section rotating swing frames 606 and tail end rotating swing frames 607 can be quickly and synchronously adjusted, thereby effectively improving the convenience of production equipment adjustment. At the same time, by connecting the components at the end of the adjusting seat 603, the middle layer steel wire mesh belt 103 can be guided at multiple angles, further improving the stability of the winding and laying of the middle layer steel wire mesh belt 103, thereby indirectly improving the ease of use of the production equipment and the overall quality of the composite pipe steel skeleton. Meanwhile, through the cooperation of the components at the top of the sliding arc support 612, and by using the buffer extension spring 614 to buffer the sides of the sliding arc support 612, the sliding stability of the components connected to the circular rotating frame 611 is effectively improved, making the adjustment process of the production equipment more stable.

[0017] The working principle and usage process of this invention: In practical applications, when using high-strength composite pipes, the inner reinforcing warp 101 and inner spiral weft 102 form the inner skeleton of the composite pipe. These inner reinforcing warp 101 and inner spiral weft 102 create a stable support structure within the composite pipe. Simultaneously, the spiral arrangement of the inner spiral weft 102 enhances the bending resistance of the composite pipe, preventing stress concentration and localized deformation. This ensures the structural integrity and long-term reliability of the composite pipe under complex working conditions. Furthermore, the outer reinforcing warp... 104 and the outer spiral weft 105 form a reinforcing structure in the outer layer of the composite pipe to improve the overall structural strength of the composite pipe and its resistance to external pressure. Then, the middle layer steel wire mesh belt 103 reinforces the inner spiral weft 102 and the outer reinforcing warp 104. Utilizing the deformable mesh characteristics of the middle layer steel wire mesh belt 103, the composite pipe can undergo slight elastic deformation after being subjected to continuous periodic external pressure, thereby effectively improving the overall structural strength and compressive strength of the composite pipe and effectively extending its service life. When it is necessary to weld the internal skeleton of the composite pipe using appropriate production equipment, the inner spiral weft 102 is electrically spark welded to the outside of the inner reinforcing warp 101 by the front winding welding seat 2 in conjunction with the central guide horizontal shaft 3. Then, when it is necessary to lay and weld the middle layer steel wire mesh 103 to the outside of the inner spiral weft 102, the middle layer steel wire mesh 103 is laid to the outside of the inner spiral weft 102 and welded by the middle layer mesh 103 winding welding seat 4. The drive gearbox 526 can drive the center drive splicing pipe 501 to rotate, and the rotation of the center drive splicing pipe 501 can drive the splicing rotating disk 502 to rotate, so that the rotation of the splicing rotating disk 502 can drive the various components installed on it to rotate synchronously. When it is necessary to install the mesh belt receiving roller 506 onto the outside of the splicing rotating disk 502, the splicing base plate 504 and the mounting protective frame 505 are snapped together through the slot to protect the outside of the mesh belt receiving roller 506. Then, the arc-shaped splicing protective rail 507 is installed onto the outside of the mounting protective frame 505 through bolts. The mounting protective frame 505 and the arc-shaped splicing protective rail 507 are then installed onto the outside of the splicing rotating disk 502 through bolts and splicing mounting base 503. The arc-shaped splicing protective rails 507 are spliced ​​end to end to form a ring through the splicing of the arc-shaped splicing protective rails 507. During the synchronous rotation of the splicing rotating disk 502 and the arc-shaped splicing protective rail 507, the arc-shaped guide slide 509 on the top of the support guide slide 508 supports and guides the arc-shaped splicing protective rail 507 to improve the overall stress of the splicing rotating disk 502 and ensure the stability of the rotation of the splicing rotating disk 502. When it is necessary to spiral the middle layer steel wire mesh belt 103 to the outside of the inner spiral weft 102, the front limiting guide roller 604 and the swing adjusting roller 605 and the components connected thereto are installed on one side of the mesh belt receiving roller 506 by connecting the adjusting seat 603. During the continuous operation of the middle layer mesh belt winding welding seat 4, the composite pipe is axially pulled by the external traction equipment during the production process to move outside the front limit guide roller 604 and swing adjustment roller 605. During the movement of the middle layer steel wire mesh belt 103, the middle section rotating swing frame 606 and the tail end rotating swing frame 607 are simultaneously driven to swing, ensuring that the middle layer steel wire mesh belt 103 is spirally wrapped around the outer side of the inner spiral weft 102 with a suitable wrap angle, so as to complete the welding and fixing of the middle layer steel wire mesh belt 103. When it is necessary to lay the middle layer steel wire mesh belt 103 axially to the outside of the inner spiral weft 102, the splicing rotating disk 502 is rotated to the appropriate position and stopped by the central drive splicing pipe 501 to ensure that the limiting pin 602 at the end of the tail limit seat 601 corresponds to the limiting through hole on the arc splicing protection rail 507 and the circular rotating frame 611. Then, the telescopic drive pipe 510 is started to actively extend, and during the extension of the telescopic drive pipe 510, the support guide slide 508 is driven to slide along the top of the limiting guide round rod 524. Furthermore, during the sliding process of the support guide slide 508, the front transmission cable 511 and the tail adjustment cable 512 will move synchronously. When the support guide slide 508 slides to the appropriate position, the limiting pin 602 at the end of the tail limiting seat 601 can be inserted into the corresponding limiting through hole to limit the arc splicing protective rail 507 and the circular rotating frame 611 in the circumferential direction. Then, the length of the front transmission cable 511 and the tail adjustment cable 512 is adjusted so that the dynamic swing plate 515 can remain horizontal in the static state. Then, the telescopic drive tube 510 is closed to cancel the limitation on the support guide slide 508 and complete the adjustment of the position of the support guide slide 508. When the support guide slide 508 and its splicing rotating disk 502 are axially pulled by the composite tube skeleton, and when the support guide slide 508 slides slightly along the axis under the action of the traction force, as the support guide slide 508 moves closer to the end of the bottom sliding guide 523, the front transmission cable 511 changes from a taut state to a slack state, one end of the dynamic swing plate 515 swings downward under the action of gravity, and during the sliding of the support guide slide 508, it will pull the tail adjustment cable 512 at the other end, and during the tightening of the tail adjustment cable 512, the tail guide wheel frame 521 pulls the movement path of the tail adjustment cable 512, so as to pull the adjustment counterweight 519 to slide along the guide bidirectional slide groove 516 through the tail adjustment cable 512. While the adjusting counterweight 519 is being pulled away from the arc-shaped support side rod 514, the dynamic swing plate 515 remains tilted under the action of the heavier counterweight front pressure block 517. Therefore, the counterweight front pressure block 517 continues to move away from the arc-shaped support side rod 514 under the action of gravity. At this time, the adjusting counterweight 519 and the counterweight front pressure block 517 move away from each other and the transmission traction spring 518 is gradually stretched. As the transmission traction spring 518 stretches, the upward traction force exerted by the transmission traction spring 518 on the end of the counterweight front pressure block 517 gradually increases, and the sliding speed of the counterweight front pressure block 517 under the action of gravity gradually decreases. At the same time, the adjusting counterweight block 519 is directly pulled by the tail adjusting cable 512, so the speed at which the adjusting counterweight block 519 moves away from the arc-shaped support side rod 514 remains unchanged. At this time, the difference between the upward traction force exerted by the transmission traction spring 518 on the counterweight front pressure block 517 and the downward force exerted by gravity on the counterweight front pressure block 517 gradually decreases. Meanwhile, the speed at which the adjusting counterweight block 519 moves away from the arc-shaped support side rod 514 remains unchanged, while the speed at which the counterweight front pressure block 517 moves away from the arc-shaped support side rod 514 decreases. As the adjusting counterweight 519 continues to move away from the arc-shaped support rod 514 and pulls the transmission traction spring 518, when the traction force of the transmission traction spring 518 gradually exceeds the weight of the front counterweight block 517, the rate at which the front counterweight block 517 moves away from the arc-shaped support rod 514 decreases, and it moves back towards the arc-shaped support rod 514. When the distance between the front counterweight block 517 and the arc-shaped support rod 514 is less than the distance between the adjusting counterweight 519 and the arc-shaped support rod 514, according to the lever principle, the dynamic swing plate 515 moves towards the adjusting counterweight 519. The direction is deflected, and while the dynamic swing plate 515 deflects in the opposite direction, the tail adjustment cable 512 is pulled in the opposite direction, thereby causing the support guide slide 508 to slide and reset away from the end of the bottom sliding guide 523. The swing of the dynamic swing plate 515 buffers and consumes the traction force on the support guide slide 508, thereby effectively improving the stability of the production equipment. The swing amplitude of the dynamic swing plate 515 is remotely and continuously monitored by the horizontal sensor 522 to ensure that the swing range of the dynamic swing plate 515 is kept within a reasonable range. When it is necessary to adjust the overall tilt angle of multiple intermediate rotating swing frames 606 and tail rotating swing frames 607, the sliding of the support guide slide 508 drives the connecting adjustment seat 603 to move closer to the circular rotating frame 611. Then, during the process of the connecting adjustment seat 603 and the circular rotating frame 611 moving closer to each other, the swing of the rubber adjusting connecting pipe 609 pulls the connecting frame 608, and then the connecting frame 608 pulls and adjusts the intermediate rotating swing frame 606, so as to realize the adjustment of the swing angle of the intermediate rotating swing frame 606 and the tail rotating swing frame 607, thereby effectively improving the convenience of adjustment during the use of production equipment. After the middle layer steel wire mesh belt 103 is laid, the steel frame is pulled forward by the traction equipment, and the outer ring reinforcing warp 104 and outer ring spiral weft 105 are welded to the outside of the middle layer steel wire mesh belt 103 by other external equipment to complete the welding and forming of the composite pipe frame.

[0018] Example 2: As Figure 16 As shown, an inner spiral weft 102 is spirally wound and welded to the outer side of the inner reinforcing warp 101. A middle layer steel wire mesh 103 is laid flat and welded to the outer side of the inner spiral weft 102. An outer spiral weft 105 is welded at equal intervals along the circumferential direction to the outer side of the middle layer steel wire mesh 103.
