Description

Technical Field

[0001] This application generally relates to the technical field of pipe processing, and more specifically to a winding device and a winding system. Background Art

[0002] Reinforced Thermoplastic Pipe (RTP) is currently mainly applied in industrial fields, especially in oil extraction, natural gas pipelines, hydrogen transmission pipelines, etc. The most prominent advantage of this pipe is its good flexibility and coiled supply, which can eliminate a large amount of connection work, flexibly adapt to the terrain, achieve very rapid and economical laying, and is very easy to relocate and reuse.

[0003] Most of the Reinforced Thermoplastic Pipes are of a three-layer structure. The inner layer is a polyethylene pipe that is corrosion-resistant and wear-resistant. The middle layer is a reinforced winding layer (the winding materials include various high-strength synthetic fibers, glass fibers, carbon fibers, and fine metal wires). The outer layer is a protective polyethylene layer. The strength of the reinforcement layer plays a decisive role in the overall pressure-bearing capacity of the RTP; therefore, how to improve the shear strength between the reinforcement layers has become a difficulty in the production of RTP. For example, in-situ consolidation techniques (such as laser, infrared, and hot air-assisted fiber winding) are adopted, and at the same time, the winding process parameters are precisely controlled (temperature gradient ±2°C, pressure ≥5 MPa, dwell time optimized). However, the existing RTP winding equipment directly lays the pre-impregnated tape on the surface of the pipe after heating, and there are problems such as the inability to accurately control parameters such as laying pressure and dwell time, and the inability to accurately control the interlayer melting bonding process.

[0080] The present application provides a winding device.

[0081] Please refer to Figures 1 to 4, The winding device 200 is used for the pipe 300. The winding device 200 includes a base frame 210, an unwinding assembly 220, a guiding assembly 230, and a rolling assembly 240. Specifically, the base frame 210 is pivotable about the axis of the pipe 300, and the base frame 210 is configured to be disposed on the outer peripheral side of the pipe 300. The unwinding assembly 220 is disposed on the base frame 210 and can pivot with the base frame 210. The unwinding assembly 220 stores a winding layer 234, and one end of the winding layer 234 away from the unwinding assembly 220 is used to connect to the outer peripheral surface of the pipe 300. The guiding assembly 230 is disposed on the base frame 210 and can pivot with the base frame 210. The guiding assembly 230 is used to be disposed between the unwinding assembly 210 and the pipe 300. The guiding assembly 230 is used to clamp a part of the winding layer 234 to enable the winding layer 234 to have a winding tension. The rolling assembly 240 is disposed on the base frame 210 and can pivot with the base frame 210. The rolling assembly 240 is used to be disposed on the outer peripheral side of the pipe 300 and cooperate with the pipe 300 to roll the winding layer 234 wound on the outer peripheral surface of the pipe 300.

[0082] For the winding device 200 according to this solution, it provides the winding tension only through the cooperation between the winding layer 234 and the guiding assembly 230, and the structure is simple. The winding device 200 is also provided with a rolling assembly 240 to ensure the bonding strength between the winding layer 234 and the outer peripheral surface of the pipe 300, reduce the delamination phenomenon that may occur during the use of the pipe 300, and improve the product quality of the pipe 300. In addition, the rolling assembly 240 can pivot with the base frame 210, and no additional driving structure needs to be provided, further simplifying the overall structure of the winding device 200. The overall structure of the winding device 200 is simplified, and on the premise of maintaining the original functions of the winding device 200, the number of devices can be simplified, thereby simplifying the transmission composition of the device, reducing the overall weight and cost investment of the device.

[0083] Now please refer to Figure 3 and Figure 4 , The rolling assembly 240 includes a first bracket 241, a pressing roller 242, and a rolling layer 243. Specifically, the first bracket 241 is connected to the base frame 210, and the first bracket 210 is configured to be adjustable in position relative to the base frame 210. The pressing roller 242 is pivotally connected to the first bracket 241 about the axis of the pressing roller 242. The rolling layer 243 is disposed on the outer peripheral surface of the pressing roller 242, and the rolling layer 243 is used to act on the aforementioned winding layer 234. Further, the pressing rollers 242 are arranged in pairs, and the two pressing rollers 242 in a pair are spaced apart in the radial direction of the pressing roller 242. The rolling layer 243 is configured in a closed shape and wound around the outer peripheral surfaces of the two pressing rollers 242 in a pair. Preferably, the rolling layer 243 is configured as a belt. The belt cooperates with the outer peripheral surface of the pipe 300 to clamp the winding layer 234 between the belt and the pipe 300 to ensure the bonding strength between the winding layer 234 and the outer peripheral surface of the pipe 300.

[0084] Please continue to refer toFigure 3 and Figure 4 ,the winding device 200 further includes a connecting shaft 235 disposed on the base frame 210 and capable of pivoting with the base frame 210. Specifically, the connecting shaft 235 is configured to be pivotally adjustable relative to the base frame 210 about the axis of the connecting shaft 235. The roller pressing assembly 240 is connected to one end of the connecting shaft 235 and can pivot with the connecting shaft 235 to adjust the angle or spacing of the roller pressing assembly 240 relative to the pipe 300. Now please refer to Figures 1 to 4 ,one end of the winding layer 234 at the unwinding assembly 220 is connected to the outer peripheral surface of the pipe 300 after being tensioned by the guiding assembly 230. For example Figure 3 and Figure 4 ,the axis of the pressing roller 242 in the roller pressing assembly 240 is arranged parallel to the axis of the pipe 300. When the base frame 210 pivots one week around the axis of the pipe 300, the winding layer 234 winds one week on the outer peripheral surface of the pipe 300. During the winding process, the roller pressing assembly 240 always presses a part of the winding layer 234, and the roller pressing layer 243 rotates with the winding layer 234, thereby driving the pressing roller 242 to pivot around the axis of the pressing roller 242. In this case, the roller pressing layer 243 is adapted to the outer peripheral surface of the pipe 300, that is, the winding layer 234 covered by the roller pressing layer 243 is generally an arc surface.

[0085] Please continue to refer to Figures 1 to 4 ,alternatively, when continuously winding the pipe 300, the winding layer 234 has a certain angular offset relative to the outer peripheral surface of the pipe 300; during the winding process, the pipe 300 moves along the axial direction of the pipe 300 (see the following description). That is, the axis of the aforementioned pressing roller 242 intersects (but is not perpendicular to) the axis of the pipe 300. For example, the position of the roller pressing assembly 240 is adjusted by rotating the connecting shaft 235. It can be understood that in order to ensure the flatness of the winding layer 234, the unwinding assembly 220 is preferably configured to be position-adjustable relative to the base frame 210, so as to realize the corresponding setting of the positions of the unwinding assembly 220, the guiding assembly 230 and the roller pressing assembly 240, so that the winding layer 234 is flatly wound on the outer peripheral surface of the pipe 300. In this case, the winding layer 234 covered by the roller pressing layer 243 is at least a line, in other words, the roller pressing assembly 240 is at least in line contact with the winding layer 234 to ensure the roller pressing effect. For example, there are multiple line contacts, or multiple discontinuous surface contacts.

[0086] Now please refer to Figure 3 and Figure 4, the winding device 200 further includes a second bracket 232. The second bracket 232 is connected to the connecting shaft 235 and can pivot with the connecting shaft 235. The guiding assembly 230 is arranged on the second bracket 232. Specifically, the guiding assembly 230 includes guiding rollers 231. The guiding rollers 231 are pivotally connected to the second bracket 232 about the axis of the guiding rollers 231. The guiding rollers 231 are arranged in pairs, and the two guiding rollers 231 in a pair are spaced apart in the radial direction of the guiding rollers 231. In the radial direction of the guiding rollers 231, the distance between the two guiding rollers 231 in a pair is adjustable, so as to adjust the clamping degree of the winding layer 234, or be able to clamp winding layers 234 with different thicknesses, ensuring that the winding layer 234 has the tension required for winding. Further, the winding device 200 further includes a heating member 233. The heating member 233 is used to heat the winding layer 234 that is about to be wound onto the outer peripheral surface of the pipe 300, so that the winding layer 234 can be better welded to the outer peripheral surface of the pipe 300. Preferably, the heating member 233 is configured as a laser heating device.

[0087] Please continue to refer to Figure 3 and Figure 4 , the winding device 200 further includes a mounting seat 260. The mounting seat 260 is arranged on the base frame 210 and can pivot with the base frame 210. Specifically, the connecting shaft 235 is connected to the mounting seat 260, and the connecting shaft 235 is configured to be pivotally adjustable relative to the mounting seat 260 about the axis of the connecting shaft 235. Further, the connecting shaft 235 is also configured to be adjustable relative to the mounting seat 260 along the extending direction of the connecting shaft 235. For example, the mounting seat 260 has a mounting hole 263 penetrating through in the thickness direction of the mounting seat 260, and the other end of the connecting shaft 235 away from the roller pressing assembly 240 penetrates into the mounting hole 263. Figure 3 and Figure 4 In, the other end of the connecting shaft 235 protrudes outward from the mounting hole 263. A threaded structure is arranged between the connecting shaft 235 and the mounting hole 263. Specifically, the mounting hole 263 is configured as a threaded hole, and the outer peripheral surface of the connecting shaft 235 is provided with an external thread adapted to the threaded hole. Rotating the connecting shaft 235 can drive the roller pressing assembly 240 to pivot, and at the same time, rotating the connecting shaft 235 multiple times can also adjust the position of the connecting shaft 235 relative to the mounting seat 260 along the extending direction of the connecting shaft 235, so as to adjust the position of the roller pressing assembly 240. According to the self-locking characteristic of the thread, it can also prevent the position of the roller pressing assembly 240 from changing relative to the base frame 210 along the extending direction of the connecting shaft 235.

[0088] Furthermore, the mounting base 260 includes a rigid portion 261 and an elastic portion 262. One end of the rigid portion 261 is connected to the base frame 210. The elastic portion 262 is connected to the other end of the rigid portion 261 away from the base frame 210. It can be understood that the elastic portion 262 can undergo elastic deformation under an external force. Specifically, the elastic portion 262 has a mounting hole 263 penetrating along the thickness direction of the mounting base 260; that is, the mounting hole 263 is provided in the elastic portion 262. Among them, the elastic portion 262 is further provided with an opening 264 communicating with the outside and the mounting hole 263. It can be understood that in order to further limit the position of the connecting shaft 235, the winding device 200 further includes a limiting component 267. The limiting component 267 is arranged between the connecting shaft 235 and the mounting base 260, and the limiting component 267 is used to limit the position of the connecting shaft 235 relative to the mounting base 260. For example, the mounting base 260 has a first limiting hole 266 penetrating therethrough. The first limiting hole 266 extends through the opening, and the first limiting hole 266 is connected to a limiting member 265. That is, the limiting component 267 includes the first limiting hole 266 and the limiting member 265. The first limiting hole 266 can be configured as a threaded hole, and the limiting member 265 is configured as a matching bolt; or, the first limiting hole 266 is configured as a common through hole, and the limiting member 265 is configured as a combination of a bolt and a nut. With such a setting, the mounting hole 263 can be tightened, so as to at least avoid the sliding of the connecting shaft 235 along the extending direction of the connecting shaft 235. Furthermore, the limiting component 267 can further include a second limiting hole, and the second limiting hole connects the outside and the mounting hole 263. The second limiting hole is configured as a threaded hole, for example, the second limiting hole is connected to a limiting member 265, and the limiting member 265 is configured as a bolt. It should be noted that the limiting member 265 connected to the second limiting hole abuts against the outer peripheral surface of the connecting shaft 235. Preferably, the second limiting holes are arranged in pairs, and the two paired second limiting holes are spaced apart along the radial direction of the connecting shaft 235, so as to limit the pivoting freedom of the connecting shaft 235 around the axis of the connecting shaft 235.

[0089] Please continue to refer to Figure 3 and Figure 4, the winding device 200 further includes a driving member 250 disposed between the connecting shaft 235 and the rolling assembly 240. One end of the driving member 250 is connected to the connecting shaft 235 and can pivot with the connecting shaft 235, and the other end of the driving member 250 away from the connecting shaft 235 is connected to the rolling assembly 240. The driving member 250 is configured to drive the rolling assembly 240 to move along the extending direction of the connecting shaft 235 to adjust the acting force between the rolling assembly 240 and the pipe 300. Specifically, a first mounting plate 251 is disposed between the driving member 250 and the rolling assembly 240. The first mounting plate 251 is connected to the first bracket 241 and the driving member 250. Preferably, the driving member 250 is configured as a four-axis cylinder. It can be understood that the cylinder includes a cylinder body and an actuator rod. A second mounting plate 252 is sleeved on the outer periphery of the cylinder body, and the cylinder further includes a plurality of guide rods, and the second mounting plate 252 is provided with a plurality of through holes adapted to the guide rods. A third mounting plate 235 is further disposed between the cylinder body and the connecting shaft 235, and the third mounting plate 235 is connected to the driving member 250 and the connecting shaft 235. The operation of the four-axis cylinder can adjust the distance between the rolling assembly 240 and the outer peripheral surface of the pipe 300, and the guide rods move along the through holes, so that the rolling assembly 240 moves more smoothly following the actuator rod of the four-axis cylinder.

[0090] Figure 3 and Figure 4 In, the unwinding assembly 220 includes an unwinding reel 221, a third bracket 222, and a pivot shaft 223. Specifically, the third bracket 222 is connected to the base frame 210 and can pivot with the base frame 210. Preferably, the position of the third bracket 222 relative to the base frame 210 is adjustable so that the positions of the unwinding assembly 220, the guiding assembly 230, and the rolling assembly 240 correspond to each other. The pivot shaft 223 is connected to the third bracket 222, and the unwinding reel 221 is sleeved on the outer periphery of the pivot shaft 223. It can be understood that the unwinding reel 221 is used to store the winding layer 234.

[0091] Now please refer back to Figure 1 and Figure 2 , the present application further provides a winding system 100, and the winding system 100 further includes a driving device, a traction assembly, and the foregoing winding device 200. Specifically, the driving device is connected to the base frame 210, and the driving device is configured to drive the base frame 210 to pivot around the axis of the pipe 300. The traction assembly is connected to the pipe 300, and the traction assembly is configured to drive the pipe 300 to move along the axial direction of the pipe 300. The winding device 200 is configured to wind the winding layer 234 around the outer peripheral surface of the pipe 300.

[0092] Now in combination with Figures 1 to 4 the working process of the winding system 100 will be described. The pipe 300 is, for example, a thermoplastic reinforced pipe, and the winding layer 234 is a continuous fiber reinforced thermoplastic resin prepreg tape.

[0093] Before winding, the positions of the unwinding assembly 220 and the connecting shaft 235 are adjusted to make the positions of the unwinding assembly 220, the guiding assembly 230, and the roll pressing assembly 240 correspond to each other. In order to perform continuous winding, in this embodiment, the axis of the pressing roller 242 intersects but is not perpendicular to the axis of the pipe 300. That is, the connecting shaft 235 can control the winding angle of the winding layer 234 relative to the pipe 300. One end of the winding layer 234 at the unwinding disk 221 is passed between the two guiding rollers 231 and led to the outer peripheral surface of the pipe 300. One end of this winding layer 234 is connected to the outer peripheral surface of the pipe 300. The winding layer 234 obtains the tension required for winding through the guiding assembly 230. The distance between the roll pressing assembly 240 and the outer peripheral surface of the pipe 300 is adjusted by the connecting shaft 235 and / or the driving member 250 so that a part of the winding layer 234 is clamped between the roll pressing layer 243 and the outer peripheral surface of the pipe 300. Start the heating element 233, the driving device, and the traction assembly to operate. The driving device drives the base frame 210 to pivot around the axis of the pipe 300, so that the winding layer 234 at the unwinding assembly 220 is continuously unwound and wound onto the outer peripheral surface of the pipe 300. Before the winding layer 234 is wound onto the pipe 300, it is heated by the heating element 233, which is beneficial to better welding of the winding layer 234 to the outer peripheral surface of the pipe 300. The traction assembly drives the pipe 300 to move along the axial direction of the pipe 300, so that the winding layer 234 is continuously wound onto the outer peripheral surface of the pipe 300. During this process, the winding layer 234 is always in contact with the roll pressing layer 243, and the winding layer 234 drives the pressing roller 242 to pivot through the roll pressing layer 243.
