Description

Technical Field

[0001] This utility model relates to the field of fiberglass reinforced plastic (FRP) sand-filled pipe processing technology, specifically to a fiberglass reinforced plastic (FRP) sand-filled pipe winding device. Background Technology

[0002] Fiberglass reinforced plastic (FRP) pipes, due to their lightweight, high strength, corrosion resistance, and long service life, are widely used in fluid transportation projects in municipal, chemical, and environmental protection fields. Their manufacturing process typically employs a winding molding technique, where reinforcing materials (such as fiberglass) are wound layer by layer onto the surface of a rotating mandrel and coated with resin, ultimately curing to form the pipe structure.

[0003] However, in the production of fiberglass pipes and fiberglass tanks, the installation and fixing of the core mold is quite cumbersome, and manual handling is required at the installation position during the assembly and disassembly process. Assembly and disassembly are time-consuming and labor-intensive, significantly increasing the idle time of the equipment and resulting in low work efficiency of the entire fiberglass product processing. Therefore, a fiberglass sand-filled pipe winding device is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a fiberglass reinforced plastic (FRP) sand-filled pipe winding device to solve the problem that the installation and fixing of the core mold is cumbersome, and that manual handling is required at the installation position during the assembly and disassembly process, which is time-consuming and labor-intensive.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fiberglass reinforced plastic (FRP) sand-filled pipe winding device, comprising a base, on which two support seats are slidably mounted relative to each other, and on which a driving assembly is provided to drive the two support seats to move relative to each other;

[0006] A lifting and placing seat is provided between the two support seats, and a winding core mold is placed on the lifting and placing seat;

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a fiberglass reinforced plastic (FRP) sand-filled pipe winding device, including a base 1 with an installation groove. A drive assembly 3 is installed on the base 1 and includes a bidirectional threaded rod 31, a forward and reverse motor 32, and two sliders 33. The bidirectional threaded rod 31 is rotatably mounted between the two inner walls of the installation groove via bearings. The bidirectional threaded rod 31 has two symmetrically arranged reverse threaded sections. The forward and reverse motor 32 is located at one end of the base 1 and is connected to the bidirectional threaded rod 31 via a coupling. The output shaft speed of the motor is 10-20 r / m. In the mounting groove, two sliders 33 respectively engage with two reverse threads of the bidirectional threaded rod 31. The guide rod 34 is fixedly installed on the inner side of the mounting groove parallel to the bidirectional threaded rod 31. At least two guide rods 34 are provided, located on both sides of the bidirectional threaded rod 31, and pass through the guide holes of the two sliders 33 to ensure that the sliders 33 slide only in a straight line and avoid deflection. The two support seats 2 are welded and fixed to the top of the sliders 33 respectively. In the actual use, the forward and reverse motor 32 is started to drive the bidirectional threaded rod 31 to rotate, so that the two sliders 33 drive the support seats 2 to move synchronously towards each other.

[0020] Specifically, a lifting and placing seat 4 is provided between the two support seats 2. The lifting and placing seat 4 includes four sets of X-shaped telescopic frames 41 and lifting seats 42. The bottom ends of the X-shaped telescopic frames 41 are connected to two sliders 33 through hinge shafts. Four horizontal sliding rods 43 are welded to the bottom of the lifting seat 42. The two upper ends of each X-shaped telescopic frame 41 are hinged to sliding sleeves 44. The two sliding sleeves 44 of each X-shaped telescopic frame 41 are slidably sleeved on the same sliding rod 43. When the support seats 2 move relative to each other, the X-shaped telescopic frames 41 unfold or fold, driving the lifting seat 42 to rise and fall vertically. During installation, when the lifting seat 42 drives the winding core mold 5 to rise to the height of the set installation position, the two support seats 2 stop moving, realizing the automatic lifting of the core mold to the precise centering position.

[0021] Specifically, the top of the lifting seat 42 has two symmetrical U-shaped placement openings 45, and six support rollers 46 are installed in each placement opening 45. The support rollers 46 are rotatably connected to the side wall of the U-shaped opening through bearings, and are used to support the rotating shaft ends on both sides of the winding core mold 5, so as to facilitate the placement and removal of the winding core mold 5.

[0022] Specifically, the top of the support base 2 is provided with a rotating base 6, which has several evenly distributed through holes 7. The end of the winding core mold 5 is provided with an insertion hole 8 that matches the through holes 7. The side of the rotating base 6 away from the lifting and placing base 4 is provided with an annular connecting base 9, which has several insertion rods 10 that pass through the through holes 7 and are inserted into the insertion holes 8. The middle of the rotating base 6 is provided with a threaded connecting rod 11, and the annular connecting base 9 is provided with a locking nut 12 that is threadedly connected to the threaded connecting rod 11. One side of the support base 2 is provided with a drive motor 13 that drives the threaded connecting rod 11 on the same side to rotate. The outer periphery of the mother 12 is provided with a radially extending handle 14. The operator rotates the locking nut 12 through the handle 14 to drive the insertion rod 10 on the annular connecting seat 9 to move along the threaded connecting rod 11. Combined with the locking mechanism of the through hole 7 of the rotating seat 6 and the insertion hole 8 of the core mold, the installation and fixing method of the core mold is simplified. The lifting and placing seat 4 automatically lifts the core mold to the precise centering position, avoiding the problem of manual handling at the installation position during the assembly and disassembly process. This achieves time-saving and labor-saving assembly and disassembly, reduces the time of equipment assembly and disassembly, and improves the overall work of fiberglass product processing.

[0023] Working principle: When changing the winding core mold 5, the hand-held part 14 is rotated to drive the locking nut 12 to rotate, causing the insertion rod 10 on the annular connecting seat 9 to move away from the insertion hole 8. Then, the drive assembly 3 is activated to drive the two support seats 2 to move away from each other. During the process of the two support seats 2 moving away from each other, the lifting placement seat 4 and the winding core mold 5 descend. After changing the winding core mold 5, the drive assembly 3 is activated to drive the two support seats 2 to move closer to each other. During the process of the two support seats 2 moving closer to each other, the lifting placement seat 4 and the winding core mold 5 rise to the installation position. Then, the hand-held part 14 is rotated in the opposite direction to drive the locking nut 12 to rotate in the opposite direction, causing the insertion rod 10 on the annular connecting seat 9 to move and insert into the insertion hole 8, thus realizing the installation.
