Description

Technical Field

[0001] This utility model relates to the field of rotating support devices, specifically a fiberglass-reinforced plastic (FRP) wound external support rotating ring device. Background Technology

[0002] In the field of mandrel manufacturing, fiberglass is typically wrapped around the mandrel to improve its strength, corrosion resistance, and other properties. During implementation, an external support rotating ring device is needed to ensure stable rotation of the mandrel, thereby guaranteeing the uniformity and quality of the fiberglass winding.

This connection structure is simple but has poor stability and cannot provide sufficient support and stability for the core mold. During the rotation of the core mold, it is difficult to withstand the huge torque and shear force generated during the fiberglass winding process, which leads to loosening of the connection and affects the normal progress of the winding process.

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] refer to Figure 1-3 A rotating ring device for external support of fiberglass winding is disclosed, used for rotating support of fiberglass winding outside a mandrel. It includes a support shaft 1, a connecting component 2, and an auxiliary component 3. The connecting component 2 is coaxially disposed at one end of the support shaft 1 and is detachably connected to the mandrel, thereby realizing the connection between the support shaft 1 and the mandrel. The auxiliary component 3 is disposed outside the connecting component 2 and is detachably connected to the mandrel, thereby strengthening the connection between the rotating ring device and the mandrel, providing sufficient support force and stability for the mandrel, and thus ensuring the normal progress of the winding process.

[0030] In some embodiments, the support shaft 1 includes a shaft body 11, a mounting plate 12, and a limiting ring 13. The shaft body 11 may be a cylindrical structure and can be placed on a rotating bracket to provide rotational support for the core mold. The shaft body 11 may be made of high-strength alloy steel, such as 40Cr steel, which has high strength and wear resistance and can withstand the weight of the core mold and various forces generated during rotation. The diameter and length of the shaft body 11 may be designed according to the size and weight of the core mold to ensure that it can provide sufficient support force. The shaft body 11 may be connected to an external drive device to provide rotational power for the core mold. This is prior art and will not be described in detail here. The mounting plate 12 is located at one end of the shaft body 11 and has mounting holes corresponding to the fixed plate 21. It can be detachably connected to the fixed plate 21 by bolts. The size and shape of the mounting plate 12 are designed according to the size of the fixed plate 21 to ensure that the connection between the two is tight and reliable. The limiting ring 13 is coaxially located on the shaft body 11 and can be fixed by welding. It can limit the axial movement of the connecting assembly 2 on the shaft body 11 and ensure the stability of the core mold position during rotation.

[0031] In some embodiments, the connecting assembly 2 includes a fixed plate 21, multiple connecting rods 22, and a connecting ring 23. The fixed plate 21 is connected to the mounting plate 12 via bolts and is coaxially arranged with the support shaft 1. The fixed plate 21 can be made of high-strength steel plate, such as Q345 steel, which has high strength and stability. The multiple connecting rods 22 are arranged in a ring at the end of the fixed plate 21 away from the support shaft 1. One end of the connecting rod 22 is connected to the fixed plate 21, and the other end is connected to the connecting ring 23. The connection can be made by welding. The connecting rods 22 can be made of high-strength alloy steel, which has high strength and bending resistance, and can transfer the supporting force of the support shaft 1 to the connecting ring 23. The connecting ring 23 is detachably connected to the core mold. The inner and outer diameters of the connecting ring 23 can be designed according to the size of the core mold so that it can fit tightly against the outer wall of the core mold. The connecting ring 23 is made of high-strength alloy steel, such as 34CrMo steel, which has high strength and corrosion resistance. The connecting component 2 is connected to the support shaft 1 via the fixed plate 21 and to the core mold via the connecting ring 23, thereby achieving a stable connection between the support shaft 1 and the core mold.

[0032] In some embodiments, the connecting component 2 further includes a plurality of first connecting holes 24, which are equally spaced on the connecting ring 23. The diameter and number of the first connecting holes 24 can be set according to the size and weight of the core mold. The connecting ring 23 and the core mold can be detachably connected by the bolt assembly cooperating with the connector on the core mold.

[0033] In some embodiments, the auxiliary component 3 includes multiple auxiliary rods 31 and multiple reinforcing rods 32. The multiple auxiliary rods 31 are arranged in a ring on the connecting ring 23 and are detachably connected to the mandrel. The auxiliary rods 31 can be made of high-strength square steel to give them high strength and stability. The two ends of the reinforcing rods 32 are welded or bolted to two adjacent auxiliary rods 31, which can enhance the overall strength and stability of the auxiliary component 3. The multiple reinforcing rods 32 form a regular polygon, which can improve the uniformity of force between the auxiliary component 3 and the mandrel, thereby improving the stability of the mandrel during rotation.

[0034] In some embodiments, the auxiliary component 3 further includes a plurality of second connection holes 33. The second connection holes 33 are located at one end of the auxiliary rod 31 near the reinforcing rod 32. The diameter and number of the second connection holes 33 can be designed according to the size and weight of the core mold. The auxiliary rod 31 and the core mold can be detachably connected by bolt assembly and other connecting parts on the core mold.

[0035] In some embodiments, two auxiliary rods 31 are symmetrically arranged on both sides of the first connecting hole 24.

[0036] In some embodiments, the connecting component 2 further includes a plurality of positioning grooves 25. The cross-section of the positioning grooves 25 may be convex. The positioning grooves 25 are located at the bottom of the connecting ring 23. The auxiliary component 3 further includes a positioning block 34. The positioning block 34 is located at one end of the auxiliary rod 31 near the connecting ring 23. The shape and size of the positioning block 34 match the positioning grooves 25. The positioning block 34 and the positioning grooves 25 are inserted into each other, which can realize the rapid positioning and pre-connection of the auxiliary rod 31 and the connecting ring 23, thereby improving the connection efficiency between the auxiliary component 3 and the connecting component 2. At the same time, it can increase the contact area between the auxiliary rod 31 and the connecting ring 23, thereby increasing the welding area between the auxiliary rod 31 and the connecting ring 23, and thus improving the connection strength between the auxiliary component 3 and the connecting component 2.

[0037] The specific working principle is as follows:

[0038] During installation, align the first connecting hole 24 with the connector on the core mold, and use bolts to fix the connecting ring 23 to the core mold. Align the second connecting hole 33 with the other connectors on the core mold, and use bolts to fix the auxiliary rod 31 to the core mold, thus completing the fixed connection between the supporting rotating ring device and the core mold. Then, place the support shaft 1 on the rotating bracket and connect it to the external rotating drive device.

[0039] Start the outer wall rotation drive device to make the support shaft 1 rotate on the rotating bracket, thereby realizing the rotation of the core mold. Then, wind fiberglass around the outside of the core mold. Winding fiberglass is an existing technology and will not be described in detail here.
