Description

Technical Field

[0001] This invention relates to the field of pipeline manufacturing technology, and specifically to an RTP pipeline winding device. Background Technology

[0002] Pipes play a crucial role in the mining industry for transporting various media. However, both simple steel and plastic pipes have significant limitations. Steel pipes are susceptible to corrosion, posing potential risks, while plastic pipes lack sufficient strength and pressure resistance to withstand the harsh mining environment. Therefore, composite material pipes have become a major trend in the industry, with RTP (Reinforced Thermoplastic Pipes) spirally wound pipes being a prime example. RTP spirally wound pipes typically employ a three-layer structure: the inner layer is usually a corrosion-resistant and wear-resistant thermoplastic pipe; the middle layer is the reinforcing layer; and the outer layer is the protective outer coating. The reinforcing layer is often made of reinforcing fibers through winding and braiding.

[0003] In the prior art, utility model patent application number CN202022039753.7 discloses an RTP tube non-metallic reinforcing tape winding device, including a worktable, a positioning disk fixed to the worktable, and a rotating disk rotatably positioned on the positioning disk. A winding part is rotatably arranged on the rotating disk. Driven by a power device, the rotating disk rotates along its own axis so that the winding part has a revolution around the RTP tube pre-passed through the central clearance hole of the rotating disk, thereby realizing the winding of the RTP tube.

[0004] However, the above-mentioned device still has shortcomings in actual use. Relying solely on the winding action makes it difficult to make the reinforcing layer tape adhere evenly and tightly to the outer wall of the pipe, which can easily lead to problems such as poor adhesion and loose tape, affecting product quality. Summary of the Invention

[0005] The purpose of this invention is to provide an RTP pipe winding device that further compacts the material strip by means of a brush rotating around the pipe, thereby solving the defects mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An RTP pipe winding device includes a winding mechanism, a pressing mechanism, and a heating mechanism arranged sequentially along the pipe conveying direction. The pressing mechanism includes a frame on which a rotating support driven by a first motor and rotating around the axis of the pipe is mounted. A brush is fixedly mounted on the rotating support. The brush has bristles that fit against the outer wall of the pipe. When the rotating support rotates, the material strip wound on the outer wall of the pipe is compacted by the brush.

[0007] As a further improvement, the rotating support includes a first turntable and a second turntable arranged along the axial direction of the pipe. Both the first and second turntables are provided with a central hole for the pipe to pass through. Multiple adjusting seats are evenly spaced around the axis of the first turntable, and a brush is fixedly installed on each adjusting seat. One end of the adjusting seat is slidably mounted on the first turntable along the radial direction. An inclined guide rail is fixedly mounted on the adjusting seat. A sliding block matching the guide rail is fixedly mounted on the second turntable. When the sliding block slides along the guide rail, it drives the adjusting seat to move radially along the first turntable.

[0008] As a further improvement, multiple guide rails are arranged in a frustum shape around the pipe.

[0009] As a further improvement, a sliding plate is fixedly installed on the adjustment seat, and a groove matching the sliding plate is provided on the first turntable, the groove extending radially along the first turntable.

[0010] As a further improvement, a telescopic rod extending along the length of the pipe is connected between the first turntable and the second turntable.

[0011] As a further improvement, the frame includes a base frame on which fixed supports and movable supports are mounted along the axial direction of the pipe. The movable supports are driven by an adjustment mechanism to move closer to or away from the fixed supports. Coaxial mounting sleeves are fixedly mounted on the first turntable and the second turntable respectively. The first turntable is rotatably mounted on the fixed support through the corresponding mounting sleeve, and the second turntable is rotatably mounted on the movable support through the corresponding mounting sleeve.

[0012] As a further improvement, a drive pulley is fixedly mounted on the motor shaft of the first motor, and a driven pulley is fixedly mounted on one of the mounting sleeves. A transmission belt connects the drive pulley and the driven pulley.

[0013] As a further improvement, the adjustment mechanism includes a guide column fixedly installed on the bottom frame, the guide column extending along the length of the pipe, and a movable bracket slidably installed on the guide column; a second motor is also installed on the bottom frame, the output end of the second motor is connected to a lead screw arranged parallel to the guide column, and the movable bracket is screwed onto the lead screw.

[0014] As a further improvement, the winding mechanism includes a support base, on which a rotating sleeve driven by a motor and rotating about its own axis is mounted. The rotating sleeve is coaxially arranged with the pipe. An installation plate is fixedly mounted coaxially at one end of the rotating sleeve. Multiple installation brackets are fixedly mounted on the installation plate at even intervals around its axis. A material tray is rotatably mounted on the installation bracket.

[0015] As a further improvement, the heating mechanism includes a duct, which has a heating channel through which a pipe passes, a cavity surrounding the heating channel inside the duct, an air inlet pipe communicating with the cavity on the outer wall of the duct, and multiple air outlet holes communicating with the cavity evenly distributed on the inner wall of the heating channel.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. A rotating bracket driven by a first motor and rotating around the axis of the pipe is installed on the frame. A brush is fixedly installed on the rotating bracket. The brush has bristles that fit against the outer wall of the pipe. When the rotating bracket rotates, it drives the brush to rotate synchronously. The bristles on the brush make close contact with the material strip on the outer wall of the pipe and evenly compact the material strip, avoiding looseness and air bubbles in the material strip, thereby improving product quality. 2. When the movable bracket moves the second turntable closer to or further away from the first turntable, it causes the slide to slide forward along the guide rail, thereby causing multiple adjustment seats to move synchronously towards or away from the center of the first turntable, thus changing the distance between the brush and the outer wall of the pipe to match pipes of different diameters, making it more widely applicable.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 6 As shown, an RTP pipe winding device includes a winding mechanism 2, a pressing mechanism 3, and a heating mechanism 4 arranged sequentially along the conveying direction of the pipe 1. In this embodiment, the pipe 1 is driven forward by a traction device, and the winding mechanism 2, the pressing mechanism 3, and the heating mechanism 4 are arranged sequentially from back to front along the conveying direction of the pipe.

[0022] like Figure 1 and Figure 2 As shown, the winding mechanism 2 includes a support base 5. A rotating sleeve 6, coaxially arranged with the pipe 1, is rotatably mounted on the support base 5 via bearings. The rotating sleeve 6 passes through the support base 5 from front to back. A drive motor for driving the rotating sleeve 6 to rotate is installed inside the support base 5. The drive motor and the rotating sleeve 6 are connected by gear or belt transmission. A coaxial mounting plate 7 is fixedly mounted to the front end of the rotating sleeve 6 with screws. A mounting frame 8 is fixedly mounted to the front side of the mounting plate 7 with screws. The pipe 1 passes through the rotating sleeve 6, the mounting plate 7, and the mounting frame 8 in sequence.

[0023] The mounting frame 8 is equipped with multiple mounting brackets 9 evenly spaced around the circumference of the pipe 1. A material tray 10 is rotatably mounted on each mounting bracket 9, and a reinforcing strip is wound onto the material tray 10. Guide wheels 11, matching the material strip, are also mounted on the mounting brackets 9 to guide the material strip, ensuring it is neatly wound onto the outer wall of the pipe 1. As the pipe 1 moves forward, the drive motor causes the rotating sleeve 6, mounting tray 7, and mounting frame 8 to rotate as a whole around the axis of the pipe 1. Simultaneously, the material strip is released from the material tray 10, guided by the guide wheels 11, and evenly wound onto the outer wall of the pipe 1.

[0024] like Figure 3 and Figure 4 As shown, the clamping mechanism 3 includes a frame, which includes a rectangular base frame 12. Fixed supports 13 and movable supports 14 are mounted on the base frame 12, which are distributed back and forth along the axial direction of the pipe 1. The lower end of the fixed support 13 is fixedly mounted on the base frame 12 by screws. The movable support 14 is driven by an adjustment mechanism and moves back and forth along the length of the pipe 1, thereby moving closer to or away from the fixed support 13.

[0025] Specifically, the adjustment mechanism includes guide posts 15 fixedly installed in the base frame 12 by screws. The guide posts 15 extend back and forth along the length of the pipe 1. A sliding sleeve 16 matching the guide posts 15 is fixedly installed on the movable bracket 14. The movable bracket 14 is slidably installed on the guide posts 15 via the sliding sleeve 16. In this embodiment, two guide posts 15 are arranged opposite each other on the left and right sides in the base frame 12, and the sliding sleeves 16 correspond one-to-one with the guide posts 15, thereby improving the stability of the movable bracket 14 sliding back and forth. A second motor 17 is also installed at the rear end of the base frame 12 by screws. The output end of the second motor 17 is coaxially connected to a lead screw 18 arranged parallel to the guide posts 15. The end of the lead screw 18 away from the second motor 17 is rotatably connected to the inner wall of the front end of the base frame 12 via a bearing. A nut 19 matching the lead screw 18 is fixedly installed on the movable bracket 14. The movable bracket 14 is screwed onto the lead screw 18 via the nut 19. The second motor 17 drives the lead screw 18 to rotate. The lead screw 18 acts on the lead screw nut 19 and drives the movable bracket 14 to slide back and forth along the guide post 15, thereby moving the movable bracket 14 closer to or away from the fixed bracket 13.

[0026] A rotating bracket 21 driven by a first motor 20 and rotating around the axis of the pipe 1 is installed on the frame. A brush 22 is fixedly installed on the rotating bracket 21. The brush 22 has bristles that fit against the outer wall of the pipe 1. When the rotating bracket 21 rotates, it drives the brush 22 to rotate synchronously. The bristles on the brush 22 make close contact with the material strip on the outer wall of the pipe 1 and evenly compact the material strip to prevent the material strip from loosening and becoming hollow.

[0027] The rotating support 21 includes a first turntable 23 and a second turntable 24 arranged along the axial direction of the pipe 1. Both the first turntable 23 and the second turntable 24 are provided with a central hole for the pipe 1 to pass through. On the side of the first turntable 23 and the second turntable 24 that are far apart from each other, a coaxially arranged mounting sleeve 25 is fixedly installed by screws. The mounting sleeve 25 on the first turntable 23 is rotatably mounted on the fixed support 13 by bearings, and the mounting sleeve 25 on the second turntable 24 is rotatably mounted on the movable support 14 by bearings. The movable support 14 slides back and forth, driving the second turntable 24 to move synchronously.

[0028] In addition, a telescopic rod 26 extending along the length of the pipe 1 is connected between the first turntable 23 and the second turntable 24. The two ends of the telescopic rod 26 are respectively fixed to the first turntable 23 and the second turntable 24 by screws. Multiple telescopic rods 26 are evenly spaced around the axis of the pipe 1. While allowing the second turntable 24 to move back and forth relative to the first turntable 23, the telescopic rod 26 drives the second turntable 24 to rotate synchronously with the first turntable 23.

[0029] In this embodiment, the first motor 20 is mounted on the fixed bracket 13 with screws. A drive pulley 27 is fixedly mounted on the motor shaft of the first motor 20, and a driven pulley 28 is fixedly mounted on the mounting sleeve 25 corresponding to the first turntable 23. A transmission belt 29 connects the drive pulley 27 and the driven pulley 28. When the first motor 20 is working, it drives the driven pulley 28 to rotate through the drive pulley 27, and then the driven pulley 28 drives the mounting sleeve 25, the first turntable 23, and the second turntable 24 to rotate as a whole around the axis of the pipe 1.

[0030] Between the first turntable 23 and the second turntable 24, multiple adjusting seats 30 are evenly spaced around the circumference of the pipe 1. Each adjusting seat 30 is fixed with a brush 22 by screws. By using multiple brushes 22 to compact the material strip from different circumferential positions, the overall compaction effect of the material strip is improved. One end of the adjusting seat 30 has an integrally formed support arm 31 extending towards the first turntable 23. The end of the support arm 31 away from the adjusting seat 30 is fixed with a sliding plate 32 by screws. The rear side of the first turntable 23 has a sliding groove 33 that matches the sliding plate 32. The sliding groove 33 extends radially along the first turntable 23. The adjusting seat 30 is slidably installed in the sliding groove 33 via the sliding plate 32. By sliding the adjusting seat 30 radially along the first turntable 23 and along the sliding groove 33, the distance between the brush 22 and the outer wall of the pipe 1 can be changed to match the use of pipes 1 with different diameters.

[0031] To facilitate simultaneous adjustment of multiple brushes 22, the outer side of the adjusting seat 30 near the second turntable 24 is provided with a slope, such as... Figure 5As shown, guide rails 34, arranged along the inclined direction, are fixedly installed on the inclined surface by screws. Multiple guide rails 34 are distributed in a frustoconical shape around the pipe 1. Support rods 35, corresponding to the adjusting seats 30, are fixedly installed on the front side of the second turntable 24 by screws. The front end of the support rod 35 is fixedly installed with a slide block 36 that matches the guide rail 34 by screws. When the slide block 36 slides along the guide rail 34, it drives the adjusting seat 30 to move radially along the first turntable 23.

[0032] The vertical distance between the front end of the guide rail 34 and the pipe 1 is relatively large, while the vertical distance between the rear end and the pipe 1 is relatively small. When the movable bracket 14 moves the second turntable 24 forward toward the first turntable 23, it causes the slide 36 to slide forward along the guide rail 34, thereby causing multiple adjusting seats 30 to move synchronously toward the center of the first turntable 23, thus reducing the distance between the brush 22 and the outer wall of the pipe 1 for use with pipes of smaller diameter. When the movable bracket 14 moves the second turntable 24 backward away from the first turntable 23, it causes the slide 36 to slide backward along the guide rail 34, thereby causing multiple adjusting seats 30 to move synchronously away from the center of the first turntable 23, thus increasing the distance between the brush 22 and the outer wall of the pipe 1 for use with pipes of larger diameter.

[0033] like Figure 6 As shown, the heating mechanism 4 includes a duct 37, with a support column 38 at the bottom of the duct 37 for fixed support. The duct 37 has a heating channel 39 through which the pipe 1 passes. A cavity 40 surrounds the heating channel 39 inside the duct 37. An air inlet pipe 41 communicating with the cavity 40 is located on the outer wall of the duct 37. Multiple air outlets communicating with the cavity 40 are evenly distributed on the inner wall of the heating channel 39, with the air outlets facing the center of the heating channel 39.

[0034] In use, the air inlet pipe 41 is connected to an external hot air source. After the hot air enters the cavity 40 through the air inlet pipe 41, it is evenly blown into the heating channel 39 through multiple air outlets to evenly heat the pipe 1 and the outer wall material strip that pass through the heating channel 39, so that the material strip and the pipe 1 are more tightly bonded.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
