DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to solve the problem that the winding machine for existing FRP pipe production needs to replace the corresponding core mold for pipes of different diameters during the winding process, and the frequent replacement causes the efficiency of the equipment to decrease during use, this embodiment provides the following technical solutions:

[0022] A reinforced composite pipe winding device includes a base 1, a core mold 2 is arranged at the upper end of the base 1, a transmission rod 17 is arranged inside the core mold 2, and the outer part of the transmission rod 17 is rotatably connected to the inner part of the core mold 2. The rotatable connection can prevent the lateral movement of the transmission rod 17 from affecting the rotation of the core mold 2. Figure 1 and Figure 3 As shown, during winding, the pipe is placed outside the core mold 2 in advance. Placing the pipe outside the core mold 2 can realize the transmission and rotation of the pipe. Six inner limiting blocks 18 are arranged in sequence at the upper and lower ends of the outer side of the transmission rod 17. The outer sides of the inner limiting blocks 18 are provided with movable cavities 19 for transmission, and the movable cavities 19 penetrate and extend to the inner and outer sides of the core mold 2. The inner limiting blocks 18 can be pushed by the lateral movement of the transmission rod 17, so that the inner limiting blocks 18 extend out of the movable cavities 19. The extension of the movable cavities 19 can fit the inner wall of the pipe to realize the fixation of the pipe.

[0023] In this embodiment, if Figure 3 and Figure 4 As shown, one side of the inner limiting block 18 is rotatably connected to the transmission rod 17 via a connecting frame 20, and the middle position of the inner limiting block 18 is rotatably connected to the core mold 2 via a connecting shaft 21. Through the rotatable connection between the connecting shaft 21 and the connecting frame 20, the transmission rod 17 can drive the inner limiting block 18 to extend during the lateral movement.

[0024] In this embodiment, a telescopic rod 6 is fixedly provided at one end of the transmission rod 17, and the telescopic rod 6 is rotatably connected to one end of the transmission rod 17 via a connecting block 23. The lateral movement position of the transmission rod 17 can be adjusted by extending and retracting the telescopic rod 6. Figure 3 and Figure 4 As shown, during the rotational connection, the rotation of the connection block 23 can make the transmission rod 17 not limit the rotation of the core mold 2 during the lateral movement, so that the transmission rod 17 can rotate with the core mold 2 and adjust the lateral position with the extension and retraction of the telescopic rod 6;

[0025] In this embodiment, a transmission ring 10 is arranged around one end of the core mold 2 facing the connecting block 23, and a transmission block 22 is arranged around one end of the transmission ring 10 facing the connecting block 23. The transmission block 22 and the transmission ring 10 are not in contact with the telescopic position of the transmission rod 17 and the telescopic rod 6. Figure 3 and Figure 5As shown, the transmission block 22, the transmission ring 10 and the core mold 2 are welded and fixed in sequence, a transmission gear 9 for transmission is arranged at the lower end of the outside of the transmission ring 10, and the outside of the transmission gear 9 is meshed and connected with the outside of the transmission ring 10, and an output motor 7 is arranged at one end of the transmission gear 9, and the output shaft of the motor 7 can drive the transmission gear 9 to rotate, and the rotation of the transmission gear 9 can drive the transmission ring 10 to rotate, and the rotation of the transmission ring 10 can directly drive the core mold 2 and the external fixed pipeline to rotate;

[0026] In this embodiment, a threaded rod 11 is provided in the middle of the base 1, and one end of the threaded rod 11 is connected to the transmission block 22 through a transmission belt 12. When the transmission ring 10 rotates to drive the core mold 2, it can also drive the transmission block 22 to rotate. The rotation of the transmission block 22 can drive the threaded rod 11 to rotate through the transmission belt 12. Figure 3 , Figure 4 and Figure 5 As shown, the threaded rod 11 can be driven to rotate while the fixed pipe is rotated through transmission, so that the winding device can be evenly wound around the outside of the pipe;

[0027] In this embodiment, both ends of the threaded rod 11 are rotatably connected to the inside of the base 1, and a sliding block 13 is provided at the upper end of the outside of the threaded rod 11, and the inside of the sliding block 13 is meshed with the outside of the threaded rod 11. The rotation of the threaded rod 11 and the restriction of the base 1 can drive the sliding block 13 to move horizontally, such as Figure 1 and Figure 3 As shown, three receiving rollers 14 are evenly distributed laterally inside the sliding block 13, and the material to be wound is placed outside the receiving rollers 14 in advance. Subsequently, as the threaded rod 11 rotates, the receiving rollers 14 move laterally to achieve uniform winding;

[0028] In this embodiment, brackets 15 for mounting are provided on both sides of the upper end of the sliding block 13, and the brackets 15 are welded and fixed to the sliding block 13. Figure 1 and Figure 2 As shown, clamping rollers 16 for clamping are provided at both ends between the two brackets 15. Through the clamping of the two clamping rollers 16, the multi-layer materials can be simultaneously wound around the outside of the pipe after being clamped, so as to realize the winding of the multi-layer composite pipe;

[0029] In this embodiment, one end of the telescopic rod 6 is fixedly connected to the lower end of the motor 7 via a connecting plate 8. Figure 1 As shown, the lower end of the connecting plate 8 is welded and fixed to the upper end of the base 1, and the rotation of the core mold 2 and the lateral movement of the transmission rod 17 can be achieved by installing the connecting plate 8;

[0030] In this embodiment, a support ring 3 is provided at the other end of the core mold 2, and the support ring 3 is rotatably connected to the core mold 2. Figure 1 and Figure 3 As shown, a roller 4 for supporting and limiting the pipe is provided at the lower end of the support ring 3, and a shock absorber 5 for clamping and supporting is provided at the lower end of the roller 4. The roller 4 can be actively pushed by the spring inside the shock absorber 5, so that the roller 4 continuously fits the support ring 3, and when the pipe is inserted into the core mold 2, the thickness of the pipe can force the spring inside the shock absorber 5 to contract, and the contraction completes the insertion of the pipe, and after the pipe is inserted, the resilience of the spring can make the roller 4 repeatedly fit the support ring 3 to prevent the pipe from falling off.

[0031] Working principle: When the device is used and the pipe is wound, the pipe is squeezed from between the support ring 3 and the roller 4 and inserted into the outside of the core mold 2, and the telescopic rod 6 is started. The extension of the telescopic rod 6 can drive the inner limit block 18 to move laterally through the transmission block 22. While the inner limit block 18 moves laterally, it can be restricted by the connecting shaft 21 to rotate, so that the inner limit block 18 rotates with the connecting shaft 21 as the center and extends from the position of the movable cavity 19, extends and squeezes the inner wall of the pipe, and the motor 7 is started. The output shaft of the motor 7 can drive the transmission gear 9 to rotate, and the rotation of the transmission gear 9 The transmission ring 10 can be driven to rotate, and the transmission ring 10 can be driven to rotate the core mold 2. The rotation of the core mold 2 can drive the external fixed pipe to rotate through the internal limiting block 18, and the transmission block 22 can be driven to rotate at the same time. The rotation of the transmission block 22 can drive the threaded rod 11 to rotate through the transmission belt 12. The rotation of the threaded rod 11 can generate relative movement with the inner wall of the sliding block 13. After the sliding block 13 is restricted by the base 1, the sliding block 13 can move laterally in a straight line, driving the winding material built into the sliding block 13 to continue to move laterally while being wound around the outside of the pipe, and evenly wound around the outside of the pipe.
