Description

Technical Field

[0001] This utility model relates to a take-up reel for rigid fireproof cables, belonging to the technical field of metal and product processing tooling equipment. Background Technology

[0002] Fire-resistant cables play a crucial role in fire protection, especially rigid fire-resistant cables, which are widely used in various locations due to their robust structure and excellent fire resistance. Because of their high rigidity and large size, the installation, transportation, and maintenance of rigid fire-resistant cables require careful handling, arrangement, and maintenance of the cables.

[0003] Currently, existing cable reels on the market are mainly designed for flexible or low-rigidity cables, often employing simple roller structures or manual winding methods. These devices primarily focus on cable winding and storage, with insufficient consideration given to the special requirements of fire-resistant and rigid cables. Cables are prone to jamming, deformation, and even damage during winding, resulting in unstable and unsmooth winding. During unloading, coils are easily dispersed and creased; the simple structural design also makes them susceptible to mechanical wear during winding and unwinding. Therefore, there is a need to design a cable reel specifically for rigid fire-resistant cables. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a take-up reel for rigid fireproof cables, which solves the problem of difficulty in taking up and unwinding rigid fireproof cables and the problem of easy creases.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: a take-up reel for rigid fireproof cables, comprising...

[0006] Base, tray,

[0007] The tray is mounted on top of the base.

[0008] A rotating device is provided at the top of the base, and the bottom of the tray is connected to the rotating device. The rotating device includes a rotating shaft and a rotating platform. The rotating shaft is fixed to the top of the base, and the rotating platform is disposed on top of the rotating shaft.

[0009] The bottom of the tray is connected to the rotating platform, and the top of the tray is provided with a take-up device that can accommodate a rigid fireproof cable. The tray can rotate around the rotating axis.

[0010] Preferably, the take-up device includes an inner ring and an outer ring, the inner ring being disposed at the center of the reel and the outer ring being disposed at the outer edge of the reel.

[0025] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1

[0027] like Figures 1-5 As shown, a reel for rigid fireproof cables includes a base 1 and a reel 2, with the reel 2 positioned on top of the base 1. A rotating device is provided on top of the base 1, and the bottom of the reel 2 is fixed to the top of the rotating device, which can drive the reel 2 to rotate.

[0028] In this embodiment, the base 1 is made of metal with a rectangular frame structure at the bottom. Support parts are provided at the bottom of the frame, and the support parts are distributed at the four corners of the bottom of the base 1. The base 1 can provide support and ensure sufficient stability, facilitating installation and subsequent handling.

[0029] A rotating device is provided at the center of the base 1. The rotating device includes a rotating shaft 11 and a rotating platform 12. The bottom of the rotating shaft 11 is fixed to the base 1, and the rotating platform 12 is fixed to the rotating shaft 11. The rotating platform 12 can rotate around the rotating shaft 11. In this embodiment, the bottom of the rotating shaft 11 is rigidly connected to the base 1, and the other end is connected to the rotating platform 12. The rotating platform 12 can rotate around the rotating shaft 11, ensuring that the disc 2 can rotate without moving the overall position of the base 1.

[0030] In this embodiment, the rotating shaft 11 is existing technology, which has been improved by the present invention. Therefore, it is not necessary to disclose its specific mechanical and circuit structures, and this does not affect the integrity of the present invention. This embodiment does not impose specific limitations here.

[0031] Reference Figure 1 , Figure 4 The reel 2 is used to carry and store rigid fireproof cables. The reel 2 is fixedly connected to the rotating platform through its bottom, so as to rotate around the rotating axis 11. The reel 2 includes a cable take-up device, a support plate 25, and an extension frame 26.

[0032] In this embodiment, the take-up device includes an inner ring 22 and an outer ring 21, forming a roll-like structure on the reel 2, which can provide space for winding and storing rigid fire-resistant cables, and the rigid fire-resistant cables can be wound between the inner ring 22 and the outer ring 21.

[0033] Specifically, the inner ring 22 is located at the center of the reel 2 and serves as an inner reference for cable winding; the outer ring 212 is located at the outer edge of the reel 2 and maintains a certain distance from the inner ring 22 to accommodate the cable. Since the rigid fire-resistant cable itself has high rigidity, the inner ring 22 and outer ring 21 provide multiple constraints during winding, preventing the reel 2 from excessively compressing the cable.

[0034] The tray 2 includes a support plate 25 and extension racks 26. The support plate 25 is located at the bottom center of the tray 2, and its bottom is connected to the rotating platform 12. In this embodiment, the support plate 25 is a rectangular metal plate, and multiple extension racks 26 are provided on the top of the support plate 25.

[0035] In this embodiment, the four extension frames 26 are arranged parallel to the four sides of the support plate 25 and extend a certain distance outward from both ends of the support plate 25. The other four extension frames 26 are respectively located at the diagonal extensions of the extension frames 26. The extension frames 26 are fixed to the support plate 25 by welding. Overall, the extension frames 26 form a skeletal structure extending outward from the center, providing support and load-bearing capacity. The extension frames 26 do not pass through the center of the support plate 25.

[0036] In this embodiment, the inner ring 22 and the outer ring 21 are fixed to the support plate 25 and the extension frame 26 respectively by a long shaft 23 and a short shaft 24. The bottom of the inner ring 22 has a long shaft 23, and the bottom of the outer ring 21 has a short shaft 24. Multiple long shafts 23 are provided at the bottom of the inner ring 22. The bottom of each long shaft 23 is fixed to the edge of the support plate 25 by welding, and the top of each long shaft 23 is fixed to the inner ring 22 by welding. This embodiment uses six long shafts 23, meaning the top of the support plate 25 is connected to the long shafts 23.

[0037] A short shaft 24 is provided at the bottom of the outer ring 21. The bottom of the short shaft 24 is fixed to the edge of the extension frame 26 by welding, and the top of the short shaft 24 is fixed to the outer ring 21 by welding. The number of short shafts 24 is the same as the number of extension frames 26. The short shafts 24 are fixed on the side of the extension frame 26 away from the support plate 25.

[0038] The long shaft 23 ensures that the inner ring 22 does not loosen during winding and rotation. The short shaft 24 can connect with the outer ring 21, allowing the outer ring 21 to form a ring support.

[0039] In this embodiment, the support plate 25 has multiple screw holes at its center, and the top of the rotating platform 12 also has multiple screw holes. The support plate 25 and the rotating platform 12 can be connected by multiple bolts. Furthermore, the bolts ensure that the center of the support plate 25 and the center of the rotating platform are on the same straight line.

[0040] In this embodiment, after the rotating shaft 11 is fixed at the top center of the base 1, it is fixed by welding, ensuring the verticality of the rotating shaft 11. The rotating platform 12 is fixed on the top of the rotating shaft 11 and can rotate around the rotating shaft 11. The rotating platform 12 is connected to the reel 2 by bolts 27, which ensures the load-bearing capacity and stability of the reel 2 and allows the reel 2 to rotate freely without moving the base 1. When winding or unwinding rigid fireproof cables, only the reel 2 needs to be rotated to wind the cable, reducing the need for repeated adjustments to the operating position during traditional cable winding processes.

[0041] The inner ring 22 and outer ring 21 are respectively fitted with the long shaft 23 and short shaft 24. The inner ring 22 is fixedly welded to the edge of the support plate 25 via the long shaft 23, ensuring that the inner ring 22 provides support during cable winding. The outer ring 21 is welded to the extension frame 26 via the short shaft 21. Multiple extension frames 26 form a structure surrounding the support plate 25, providing constraints corresponding to the inner ring 22 during rigid cable winding, ensuring neat cable winding. By setting the inner ring 22 and outer ring 21 on the reel 2, it is ensured that the rigid fire-resistant cable will not undergo significant deformation or local collapse when the reel 2 stores the rigid fire-resistant cable. The weight and winding force generated when the cable is wound between the inner ring 22 and outer ring 21 mainly act on the support plate 25 and extension frame 26, avoiding localized stress concentration and improving the service life and safety of the rigid fire-resistant cable.

[0042] This embodiment uses a rotating device on top of the base 1 to allow the reel 2 to rotate smoothly, reducing the physical exertion of operators during the cable winding process and minimizing space occupation and repeated relocation. The inner ring 22 and outer ring 21 cooperate to provide sufficient winding space, preventing bending or damage to the rigid fire-resistant cable caused by excessively small diameter or uneven stress, thus maintaining the fire-resistant characteristics and electrical performance of the rigid fire-resistant cable. The support plate 26 is bolted to the rotating platform 12, allowing for quick disassembly when needed, facilitating the replacement or maintenance of various components. Furthermore, the rotating shaft 11 is easy to lubricate and tighten, ensuring long-term reliability.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
